How does a garbage truck work?

A garbage truck is a truck specially designed to collect municipal solid waste and transport it to a solid waste treatment facility, such as a landfill, recycling center or transfer station. The technical names include garbage collection vehicles and garbage collection vehicles (RCV), which are common in most urban areas. So, how does the garbage truck work?

What is the working principle of garbage truck?

The garbage truck is loaded by sanitation engineers along the nearby streets, and the garbage is loaded into the hopper at the rear of the rear loader truck. The hydraulic cylinder operates the compaction mechanism, which takes the garbage out of the hopper and puts it into the body of the truck. As more and more rubbish is put into the body, the more rubbish is compressed. Since the compaction unit is located on the outside of the truck body, it can prevent garbage from falling off the truck when the truck is full or moving. After the truck is full, the driver dumps the garbage into the garbage bin. The rear of the truck tilts like a dump truck, and the hydraulic cylinder moves the compaction plate away. Then dump the garbage out of the truck, and then dump it out with a hose.

 

First of all, the garbage is pushed into the compartment by the on-board garbage propeller (negative pressure mechanism), so that the garbage has a higher density and is more evenly distributed in the compartment until it is full. The box, loader, and sewage tank of the compression garbage truck are all sealed and welded with high-quality carbon steel plates, which have the advantages of high strength, light weight, and no secondary pollution.

Then, when the garbage truck's filler hopper is filled with garbage, the scraper opens, and the skateboard starts the scraper to move all the way down, inserts it into the garbage for splitting and initial compression. The scraper rotates forward to further compact the garbage, and the scraper is in place. The skateboard moves upwards, compacts and fills the trash into the trash can, and then returns to the starting position.

Finally, the entire process is automatically controlled. When the garbage is continuously pressed and filled, the dozer under the squeezing force gradually overcomes the back pressure and gradually shrinks, realizing the two-way compression of the garbage and evenly spreading the entire garbage bin. When the compression garbage truck unloads the garbage at the disposal (or landfill) site, the loader is lifted, the push shovel moves backward, and the garbage in the garbage bin is pushed out along the horizontal target.

 

Introduction of the frame structure of Chengli compression garbage truck when it is working

The seal of the compression garbage truck effectively avoids secondary pollution. The garbage is in a sealed state during compression, filling and transportation. The junction surface of the garbage can and the filler is sealed with a special rubber sealing strip. The waste water tank formed at the rear of the shovel has a waste water tank at the bottom of the filler, and its water inlet can receive the waste water that leaks due to the aging or damage of the sealing strip between the waste container and the filler during the operation process. The waste water tank is placed on the waste water tank. There is an air cylinder to control a certain artificially controlled sewage valve to facilitate the discharge of sewage in designated places. The filler cover completely conceals the feeding port of the filler, which avoids the phenomenon of dust flying caused by the disturbance of the air flow in the tail of the garbage truck during the transfer process.

 

Electric hydraulic control system

The control system of the compression garbage truck comprehensively manipulates the benefits of electric control, air control and hydraulic control. The air control system is controlled by the electronic control system, and the hydraulic valve group is controlled by the air control system, which effectively solves the hydraulic system and the electrical system. The problem of the interface problem, fully manipulate the multi-way directional valve to resist oil pollution than the electromagnetic directional valve, and prevent the valve from sticking.

 

Electric control system

Imported PLC (programmable controller) integrated control, the control circuit is generated in the PLC, the logic loop ensures that the control instructions are implemented in order, and at the same time ensures that the control instructions are interlocked, and only the external wiring is connected, which reduces the occurrence of failures. Things caused by misoperation are prohibited; the additional brake button can prohibit the garbage filling mechanism in any situation or any position to ensure the safety of homework personnel and installation equipment.

 

Convenient control

The operation control box is installed in the cab and the rear of the car. The operation control box in the cab can control pushing and unloading and select the operation mode (such as automatic or manual). The work control box in the rear of the car can control the pressing and filling machine. The homework of the organization, manipulation and manipulation is very convenient. In addition, in the landfill, operators can complete unloading and sewage discharge without getting off the vehicle. Wire remote control assembly can be selected according to user requirements.

 

Various bucket turning (bucket) mechanisms

Different users can choose different bucket (bucket) mechanisms according to different garbage collection conditions: standard garbage iron bucket (300 liters), plastic garbage can (240 liters), small garbage hopper (800 liters), sealed Covered garbage hopper (1400 liters). High-quality imported components The key components of the electrical and hydraulic system are imported components, such as PLC, proximity switches, buttons, cylinder seals, etc., to ensure that the garbage truck's control system is reliable and assured.

 

Take compressed garbage truck as an example to summarize the working process and steps of garbage truck

When the garbage truck's filling hopper is filled with garbage, the scraper opens, and the skateboard drives the scraper to move downwards, inserts it into the garbage for crushing and first compression. The scraper rotates forward to further compact the garbage. After the scraper is in place, it moves upward with the skateboard. Move, compact and fill the trash into the trash bin, and then return to the starting position. The entire working process is automatically controlled. When the garbage is continuously pressed and filled, the dozer will gradually retreat over the back pressure under the action of the squeezing force to realize the two-way compression of the garbage and evenly fill the entire garbage bin.

 

①It is the starting position. When the filling hopper is filled with garbage, the scraper is opened and ready to insert loose garbage.

②The skateboard drives the scraper to move down together and inserts it into the garbage for crushing and first compression.

③The scraper rotates forward to further compact the garbage.

④After the scraper is in place, it moves upward with the skateboard to compactly fill the garbage into the garbage bin and return to the starting position. In the process of continuous pressing and filling of garbage, the dozer gradually retreats under the action of squeezing force to overcome the back pressure, so that the garbage can evenly fill the entire garbage bin.

⑤After the garbage truck is filled with garbage, the garbage bin is completely closed, and it will not pollute the environment during the transfer.

⑥When the garbage truck unloads the garbage at the disposal (or landfill) site, it first raises the filler, opens the rear end of the garbage bin, and moves backwards from the front end of the garbage bin, and removes the waste in the garbage bin in a horizontal direction. Rubbish roll out.

⑦The garbage unloading is done by directly ejecting the filled garbage through the push plate.
