How does the self-loading garbage truck work?

Self-loading garbage truck is a kind of garbage truck that has a very large demand in the sanitation vehicle market in recent years. This model is used in conjunction with plastic square drums or iron drums for the collection and transfer of urban domestic garbage trucks. The hanging bucket garbage truck is small in size, easy to operate, and has the function of self-loading and self-unloading, which greatly reduces the labor intensity of sanitation workers. It is very suitable for use in areas with narrow roads such as residential areas, streets, and rural areas.

Working status of self-loading garbage truck

One of the most notable features of the self-loading garbage truck is that the garbage bin full of garbage is lifted by the garbage bin lifting mechanism and automatically dumped into the box of the pull-through garbage truck. Today we will introduce the lifting mechanism of the self-loading garbage truck.

Self-loading Garbage Truck

The lifting mechanism of the self-loading garbage truck is mainly composed of hydraulic cylinders, lifting arms, pull rods, lifting frames, turning frames, rockers, rollers and guide rails.

When the self-loading garbage truck needs to load garbage, the control handle of the hydraulic cylinder is moved, the hydraulic system provides power through the hydraulic pump, and the piston rod of the hydraulic cylinder is pushed out, and the lifting arm rotates around the distance between it and the box under the thrust of the piston rod. The hinge point swings, and the lifting arm drives the pull rod to move upwards, and then drives the lifting frame with the trash can to move upwards along the secondary guide rail of the reversing frame until the trash can touches the pressing plate on the reversing frame, and drives the reversing frame to move upwards along the main rail.

When the rollers at the upper end of the turning frame move to the end of the curved track at the top of the main rail, the upper rollers are blocked and stop, and at the same time, the pull rod continues to pull up the lifting frame, so that the axis line of the upper rollers of the turning frame is the turning axis to turn over the trash can until the trash can is finished. Garbage is automatically dumped.

Self-loading Garbage Truck

After the garbage is emptied, oil is reversely fed through the double-acting hydraulic cylinder, and the piston rod starts to retract. The lifting arm swings in the opposite direction, so that the garbage can returns to the initial position, and the working process of automatically filling garbage is completed.

Self-loading garbage trucks not only have a wide range of functions, but also have strong scalability. Add a compression push plate to the box of the self-loading garbage truck to become a compressed self-loading garbage truck. Add filter plate in the box, it can be used as a kitchen garbage truck. In addition, we can also add a weighing function to the self-loading garbage truck to detect the amount of garbage collected and so on.

Process steps of forging shaft forgings

Shaft forgings are metals formed by forging and pressing after solid-state heating. It requires the metal to have good thermoplasticity. Generally, shaft forgings are steel parts. It has high strength and good plasticity, and is suitable for manufacturing important parts with high stress and high requirements. Such as bolts, shafts, gears, etc.

The specific steps of the forging process are as follows:

Material calculation and blanking are one of the important links to improve the utilization rate of materials and realize the refinement of blanks. Excessive material not only causes waste, but also increases cavity wear and energy consumption. If there is no allowance for blanking, it will increase the difficulty of process adjustment and increase the scrap rate. In addition, the quality of the blanking end face also has an impact on the process and the quality of the shaft forging.


The purpose of heating is to reduce the forging deformation force and improve metal plasticity. But heating also brings a series of problems, such as oxidation, decarburization, overheating and overburning. Accurate control of the initial forging and final forging temperature has a great influence on the structure and performance of the product.

Flame furnace heating has the advantages of low cost and strong applicability, but the heating time is long, oxidation and decarburization are easy to occur, and the working conditions need to be continuously improved. Electric induction heating has the advantages of rapid heating and less oxidation, but it has poor adaptability to changes in product shape, size and material.

Forging forming is produced under the action of external force. Therefore, correct calculation of deformation force is the basis for selecting equipment and performing mold check. Stress-strain analysis of the deformed body is also indispensable for optimizing the process and controlling the microstructure and properties of the shaft forging.

Therefore, the quality analysis of shaft forgings can generally be divided into the stage of on-site investigation, the stage of experimental research and analysis, the stage of proposing solutions and prevention countermeasures. Before implementing these stages of work, it is best to formulate an implementation plan, including the tasks, work procedures, and completion time of these three stages. Appropriate additions and modifications can be made to this embodiment during implementation. Making an implementation plan is an important part of analyzing the quality problems of large and complex shaft forgings and used parts.

Causes and treatment methods of oil leakage of harmonic reducer bearing end cover

Harmonic reducer bearings are produced for matching harmonic reducers. They are compact in shape and have mounting holes for easy installation. They are suitable for various types of harmonic reducers. Oil leakage from the end cover of harmonic reducer bearings is also common. In response to this problem, relevant personnel have summarized the causes and treatment methods of oil leakage, let’s take a look~

Causes of oil leakage from the bearing end cover of the harmonic reducer

1. For the oil leakage of the non-shaft extension cover, the main reason is that the gap between the end cover and the box body is relatively large.

2. The main reasons for the oil leakage of the end cover of the shaft extension are that the gap between the end cover and the box is large, the input or output shaft and the inner hole of the end cover are missing or the seal is damaged, the vent plug is blocked, and the oil level is too high.

The treatment method of oil leakage of the bearing end cover of the harmonic reducer

crossed roller bearings

1. For the non-shaft extension cover, it can be reprocessed to reduce the gap. Before installation, apply even sealant on each connection surface and press it tightly. leak.

2. For the bearing cover of the shaft extension, in addition to ensuring the gap between the end cover and the joint surface of the box body, sealing elements and oil drainage plates should be added to the end cover.

3. Add a drainage plate on the inner side of the bearing close to the tank wall, so that the oil thrown on the drainage plate can be drained into the oil pool.

4. The rotation range of the drainage plate in the bearing may be very large. In order to further prevent leakage, a felt sealing ring can be added in the end cover, and the same drainage hole as the fish felt groove can be set on the end cover, even if the oil leaks Into the felt ring, the centrifugal effect can also drain it into the box through the drainage hole, thus effectively cutting off the leakage channel.

5. There is a ventilator installed on the harmonic reducer. If the vent hole is blocked, the temperature of the box will rise, the gas will expand, and the pressure will increase, which will aggravate the oil leakage. Therefore, it is necessary to ensure that the vent hole is not blocked, so that The internal and external pressure of the reduction box is balanced, which can effectively prevent leakage.

6. The increase of oil resistance will reduce the efficiency of the machine, so the amount of oil added must be appropriate, and the depth of the gear in the oil cannot exceed the height of another tooth, because the oil is stirred violently, which will increase the oil temperature and accelerate leakage.

The above article describes in detail the solution to the oil leakage of the bearing end cover of the harmonic reducer. It is worth noting that when selecting the felt ring, the size must be based on the size of the felt groove and the diameter of the shaft. Pay attention to ensure that The tolerance of the shaft and the content of the felt ring is matched, so that the oil leakage of the bearing end cover can be effectively prevented.

Application of coal centrifuge in coal industry

With the development of clean coal technology, the coal slime water process in coal preparation plants shall be limited by 0.5mm to determine the classification of coal slime. In order to meet the needs of the market, especially the requirements for dehydration of coal slime with particle size of 2~0.5mm in the separation process segmentation , it is necessary to develop a new type of centrifuge.

In this way, the coal can be recovered to the maximum extent, thereby improving the recovery rate of clean coal, improving the economic benefits of coal preparation enterprises, protecting the environment, and saving energy. Such a centrifuge product has a large processing capacity and low product moisture, which greatly reduces the burden on the coal slime water treatment system, achieves good results, and can simplify the coal slime water treatment process.

The centrifuge machine developed this time is mainly used for the dehydration of 2~0.5mm fine coal. The coal centrifuge has the characteristics of small investment, small system transformation, and good process effect. It will become the first choice for the transformation of old plants and new coal preparation plants. , due to the small particle size of the separated solid particles, it can not only be used in the coal preparation industry, but also suitable for solid-liquid separation in the chemical, pharmaceutical, food and environmental protection industries, with good business and social prospects!

The separation and dehydration of coal centrifuge is to use gravity, mechanical force or heating and drying methods to separate solids and liquids to reduce the moisture content of wet materials. The use of wet dehydration operation is an important part of coal preparation in coal preparation plants. The main purpose of coal centrifuge dehydration separation is:

coal centrifuge

(1) Reduce the moisture in coal preparation products to ensure the transportation needs. In coal preparation plants, the comprehensive moisture content of various clean coals is generally required to reach 8% to 10%, and the requirement in alpine regions is below 8%. Wet coal preparation will contain a lot of moisture. If coking coal is used for coal preparation, the coal moisture will be high, not only the coking time will be longer, the production volume will be reduced, the amount of gas used for the coke oven will be larger, and the service life will be shortened.

(2) Wash and reuse to save water. Wet coal preparation consumes a lot of water. Under normal circumstances, the jig machine uses 3 tons of water for processing 1 ton of raw coal; 1 ton of raw coal uses 0.7 tons of water, and 1 ton of fine coal requires about 1.2 to 2.0 tons of water, so our water resources will cause a lot of waste.

In addition, before wind coal preparation, if the coal contains a lot of water, it needs to be dehydrated first. Coal separation and dehydration methods include: gravity dehydration, mechanical dehydration, thermal dehydration, physical chemistry, etc. Several commonly used methods are: gravity dehydration, mechanical centrifugal dehydration and thermal heating dehydration. In the coal preparation plant, the dehydration of coal is carried out in stages.
