Correct operating procedures for agricultural tractors

In our agricultural planting, we must reasonably grasp the production efficiency and use our tractors reasonably so as to make our vehicle braking more flexible, so how should we operate correctly during the operation woolen cloth?

Start

1. After the tractor starts normally, observe the surrounding environment, and after confirming that there is no obstacle, close the door and send a signal.

2. Disengage the tractor clutch, push the shift lever into the appropriate gear, and shift the gear smoothly and accurately.

3. Gradually increase the accelerator while slowly engaging the clutch to make the tractor start smoothly. The process of engaging the clutch should be fast and then slow. After the tractor has moved away, the clutch pedal can be fully released. Do not step on the clutch pedal while driving to avoid early wear of the clutch friction plates

Variable speed

When a tractor is driving, with the change of environmental conditions, it is necessary to continuously change the driving speed. Whether the tractor can shift gears in a timely, accurate and rapid manner has a great influence on prolonging the service life of the locomotive, ensuring smooth driving and saving fuel.

1. Selection of gears

Changing the gear is actually changing the ratio of the engine speed to the transmission shaft speed. The lower the gear, the greater the speed ratio, and the greater the torque and traction. Conversely, the higher the gear, the less torque and traction you get.

During driving, when the movement resistance increases and requires large traction (such as uphill, heavy load, etc.). The low-speed gear should be selected; but the low-speed gear has low vehicle speed, high engine speed, fast temperature rise, and large fuel consumption, so the low-speed driving time should be as short as possible.

The medium-speed gear is a transition gear from low to high or from high to low, and is usually selected when turning, crossing a bridge or when it is difficult to pass. When the road conditions are good and the engine has sufficient power, the high-speed gear should be selected.

High-speed gear travels fast and saves fuel, but traffic safety must be ensured.

2. The operation of shifting from low-speed to high-speed

1) Refuel to increase the speed (rushing), the rushing should be stable, the rushing time varies according to the load of the locomotive, the rushing time is longer when the load is heavy, and the rushing distance of the high-speed gear is longer than that of the low-speed gear;

2) Lift the accelerator, step on the clutch pedal, and place the gear lever in the neutral position;

3) Engage the clutch, then disengage the clutch and quickly shift the shift lever to a higher gear;

4) Refuel smoothly and shift is completed；

Detailed introduction and spectral range of LED grow lights

Light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation.

LED plant growth light is a kind of lamp that uses LED as the light source, and needs sunlight according to the law of plant growth.

LED grow light helps to shorten the growth cycle of plants, because the light source of this light is mainly composed of red and blue light sources, using the most sensitive light band for plants, red light wavelengths use 620-630nm and 640-660nm, blue light wavelengths 450-460nm and 460-470nm were used. It allows plants to promote the differentiation of multiple lateral branches and buds during the growth process, accelerate the growth of roots, stems and leaves, accelerate the synthesis of plant carbohydrates and vitamin synthesis, and shorten the growth cycle.

The large number of LEDs in vertical grow rack systems should indicate that LED grow lights are especially suitable for artificial light-controlled plant facility cultivation environments.

The color temperature and lumens of artificial light sources are seen by the eyes of living things, while the demand of plants for light is photosynthesis, which is determined by the radiation value regardless of color temperature and lumens.

The effect of spectral range on plant physiology

(1) 280~315nm––> This wavelength is already ultraviolet light, and it has the function of direct suppressive growth for the growth of various animals, plants and even fungi, and has minimal impact on the morphological and physiological processes.

(2) 315~400nm––> This kind of light wave is also far-ultraviolet light. Although there is no ultraviolet light to harm plants, it has no direct effect on plant growth, and the absorption of chlorophyll is small, which affects the photoperiod effect and prevents stem elongation.

(3) 400~520nm (blue) –> Such wavelengths can directly develop the roots and stems of plants, and have the largest absorption ratio of chlorophyll and carotenoids, and have the greatest impact on photosynthesis.

What are the precautions for daily maintenance of linear vibrating screen?

Linear vibrating screen is a kind of vibrating screen, which is widely used in many industries. The equipment is simple to use and has good effect, so it is favored by many users. Although the linear vibrating screen is easy to use, it still needs our careful maintenance during use.

Usually, the linear vibrating screens we see are driven by dual vibration motors. When the two vibration motors are synchronized and counter-rotated, the exciting force generated by the eccentric block cancels each other in the direction parallel to the motor axis, and when the vertical vibration The direction of the motor shaft is stacked as a resultant force, so the motion trajectory of the screen machine is a straight line.

The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the self-gravity of the material, the material is thrown up on the screen surface and moves forward in a straight line, so as to achieve the purpose of screening and grading the material. In the process of use, the equipment needs frequent maintenance. During the maintenance, the following points need our attention.

Linear Vibrating Screen

1. In the early stage of operation, check the bolts at least once a day to prevent loosening.

2. When it is used again after being left for a long time, the insulation resistance should be measured, which should be greater than 0.5 megohm for the measurement of a 500-volt megger.

3. The vibrating screen and the screen carrier are equipped with special damping rubber, so as to achieve the longest service life. The rubber strip should be properly located between the two, and the damaged damping rubber strip should be replaced.

4. When the rotation direction of the motor does not meet the requirements, adjust the phase sequence of the power supply.

How to properly adjust a tractor clutch

The clutch is an essential and important part on the tractor. The clutch gradually engages the engine with the driveline, ensuring a smooth start of the tractor. When the transmission needs to change gears according to the driving of the tractor, the clutch can temporarily cut off the power transmission of the engine to ensure the smooth shifting of the transmission. The clutch also has overload protection, preventing damage from overloading the driveline and PTO by slipping the friction linings.

However, during the use of the clutch, due to natural wear and improper use and operation, the wear of the clutch transmission mechanism and the wear of the friction plate cause the clutch to slip during the operation of the tractor, and the clutch is not completely separated, which affects the normal use of the tractor. Therefore, the clutch should be used correctly during use, and maintenance and adjustment should be carried out in time to reduce the incidence of damage to the tractor clutch and prolong the service life.

1. Correct use of clutch

When driving a tractor, when operating the clutch, the disengagement should be quick and complete, and the engagement should be smooth and soft.

When the tractor is working, do not put your foot on the clutch pedal, let alone control the speed of the vehicle with a half-clutch method. Immediately after the clutch is engaged, take your foot off the pedal to avoid the clutch being half-engaged. Use the clutch reasonably, and do not use the method of slamming the clutch to overcome the trapping, overloading and overcoming obstacles. The tractor should not start with a high gear with a load, it should be in a low gear first, and then change into a high gear after starting.

2. Correct adjustment method of clutch

During the use of the clutch, due to the wear and tear of the parts, the clutch will slip or the clutch will not be completely separated. Therefore, it should be adjusted in time. In order to make the clutch work normally, it is necessary to ensure that there is a clearance of 2-3 mm between the release bearing and the inner end faces of the three release levers. When the clutch pedal is depressed until the clearance is eliminated, the travel required by the lower end of the release rocker arm along the axis of the limit bolt is called “free travel”.

The compact shelves can be divided into intelligent compact racks and manual compact racks. The same feature of both is to save space, Intensive. You can also think that they are the same office equipment product, but in terms of details, there are still quite a few differences between manual shelves and smart shelves. What are the specific differences? Let’s take a look together~

The difference between manual shelves and smart shelves

1. Different advantages
​​
Smart Shelves: Smart Shelves are based on Shelves, with intelligent control as the core, and intelligent reticulated Shelves controlled by manual, electric, and computer controls. They can perform remote operations and perform automatic control in a wide range. The three different transmission modes are independent of each other without any interference. It has automatic positioning, voice control, face unlock, remote control and other functions.

WHAT IS THE RELATIONSHIP BETWEEN THE SOLUBILITY OF CALCIUM HYDROXIDE AND TEMPERATURE?

Calcium hydroxide is a substance that can be dissolved in water, but its solubility decreases as the temperature increases. Due to the particularity of the decrease in the solubility of calcium hydroxide with temperature changes, many people can’t help asking questions, causing calcium hydroxide The relationship between solubility and temperature What are the influencing factors of this state? With this question in mind, the calcium hydroxide production line manufacturer will introduce the relationship between the solubility of calcium hydroxide and temperature.

THE RELATIONSHIP BETWEEN CALCIUM HYDROXIDE SOLUBILITY AND TEMPERATURE:

1. After a series of tests, we found that during the reaction process, a lot of heat was released, which made the temperature of the solution rise. During the whole reaction process, the mass of water in the solution decreases due to the consumption of part of the water.

2. Due to the decrease of the solvent in the solution and the increase of the solution temperature, part of the solute Ca(OH)2 is precipitated, which makes the quality of the solute in the solution decrease. After a while, as the temperature of the solution decreases, when the temperature of the solution returns to the original temperature, it still cannot reach the original quality.

3. The subtle changes in the quality of the solvent and the solute in the solution cause similar fluctuations in the quality of the solution. The quality of the solution first decreases and then increases a little bit. Compared with the beginning, the quality of the obtained solution is less than that before adding quicklime. the quality of the solution.

4. The temperature of the solution increases first and then decreases, and slowly returns to the original temperature. The obtained solution is still a saturated solution at the original temperature, so during the whole process, the solute mass fraction first decreases and then increases to the original value.

COMPARED WITH THE TRADITIONAL CALCIUM HYDROXIDE PRODUCTION PROCESS, WHAT ARE THE ADVANTAGES OF THE CALCIUM HYDROXIDE PRODUCTION LINE?

The traditional production process of calcium hydroxide is mainly based on manual production, but there are many disadvantages. With the development of society, the scale of mechanized production has gradually expanded, replacing manual production, and it has been widely used. Today, the editor of Zhongcai is here. Let me introduce to you the advantages of calcium hydroxide production line compared with traditional calcium hydroxide production process!

DISADVANTAGES OF TRADITIONAL CALCIUM HYDROXIDE PRODUCTION PROCESS

15T installation site of Weinan Yaobai Cement Plant

1. Pollution of the environment

Because it is produced by hand, a large amount of high-temperature steam and dust generated during the digestion process will permeate everywhere, and the pollution radius can reach more than 1,000 meters, causing serious damage to the forests and crops within the polluted area.

2. Affect health

Manual production is labor-intensive, the production environment is poor, and the pollution of dust and steam will affect the physical and mental health of production workers.

3. Low production efficiency

The efficiency of manual production is very low. On average, each person does not exceed 1 ton of finished calcium hydroxide during the day. The production scale is small, the average annual output is only a few hundred tons, and the larger scale is only about 5,000 tons. The demand of pharmaceutical food, petroleum, papermaking and other industries.

4. Unstable quality

Manual production is all judged by the experience of the staff. Everyone’s experience is different, so the quality of the finished products is uneven, sometimes good and sometimes bad, which cannot meet the requirements of the petrochemical industry and the fine chemical industry.

How to prevent auditorium chairs from wearing out?

As a public chair with high frequency, auditorium chairs are widely used in auditoriums, conference rooms, theaters, cinemas and other places. Natural wear and tear is very common. How to reduce the wear and tear of auditorium chairs has become an auditorium chair. Manufacturers and customers worry about problems.

First of all, we must understand the wear resistance of auditorium chairs. This should be judged according to the information provided by auditorium chair manufacturers. Different wear resistance properties have different degrees of wear and tear, and the way of wear should also be understood. The wear mainly comes from the wear of the sponge, the wear of the footrest and the wear of the seat back plate.

The wear of sponge is often caused by insufficient load-bearing capacity or excessive load-bearing capacity, causing abnormal wear, failure to rebound, deformation, no bearing capacity, hardening, etc., all of which are sponge wear, and sponge wear is often irreversible. Therefore, to prevent the wear of the sponge, it is necessary to know the bearing capacity of the sponge. This can only be obtained after many tests by the manufacturer. Strictly complying with the data given by the manufacturer is the most effective way to prevent the sponge from wearing.

Multimedia classroom soft chair

The wear of the footrest is often caused by the oxidation of the writing board and the foot. To prevent the oxidation of the foot, it is necessary to maintain the indoor humidity, not too humid, because the metal and oxygen are more easily oxidized in a humid environment, and regularly check whether the foot is rusted. Once the signs of rusting are found, they should be treated with a solution that prevents rusting in time, and the writing board should also be regularly checked for wear and tear, and whether the joints are loose.

The wear of the seat back panel will come from changes in the environment, because the seat back panel is mostly wood and paint. If the environment is too dry and the temperature is high, the seat back panel will crack and lose the paint, and if the environment is too humid, it will become moldy and paint off. , so maintaining indoor temperature and humidity is an effective way to protect auditorium chairs and must not be underestimated.
