Cheng Li compression (back loading and unloading) garbage truck working principle

The rear-mounted garbage truck, also known as a compact garbage truck (hereinafter referred to as garbage truck), is a special vehicle used for collecting, transporting, and unloading garbage, barrels, and bulk garbage in cities and towns. Garbage is pushed into the trunk by a vehicle garbage propeller, also called a vacuum mechanism, so that the garbage is denser and more evenly distributed in the trunk until it is full; the collection and transportation mode of the garbage truck is widely used in the world. With regard to garbage collection and transportation methods, the functions of its special devices are powered by automobile engines, and are achieved manually or electronically by hydraulic mechanisms. The box and loader of the vehicle, also known as the bucket body and the recovery tank, are all welded with high-quality carbon steel plates and have the advantages of high strength, light weight, and no secondary pollution.
When the filling hopper is full of trash, the scraper opens, and the sliding board drives the scraper to move downwards, inserts garbage into the garbage and breaks it for the first time. The scraper sways forward and further compacts the garbage. The scraper moves into position and moves upwards with the skid. Compact the trash and fill it in the bin, then return to the starting position. The whole work process is automatically controlled. When the garbage is continuously filled and pressed, the push shovel under the action of the extrusion force overcomes the back pressure and gradually retreats to realize bidirectional compression of the garbage and evenly fills the entire garbage can.
When the garbage compactor unloads the garbage while handling (or burying) the site, lift the filler and push the shovel backwards to push the garbage in the bin horizontally.
● The frame structure trash can adopts the reinforced frame and steel plate welded to form a solid frame structure. The bottom surface is a concave plane. The sides and the top surface are circular arc surfaces. The appearance is beautiful, the weight is light, the force is good, and the deformation is not; the shovel is made of steel pipe skeleton. The structure of the panel and the folding panel is not only light and exquisite, but also can make the garbage evenly distributed and the discharging is clean; the filling device is mainly composed of a filler shell, a slide plate, a scraper and Other components, and each component adopts a beam plate with good force or Box structure, firm structure, light weight;
● Sealing treatment eliminates secondary pollution. The waste is kept closed during shrinkage filling and transportation. The joint between the waste bin and the filler is sealed with a special rubber seal, and the front of the waste bin is composed of a waste container and the back of the shovel. The volume of the tank is 1.35 m, and the recovery tank has a recovery tank with a volume of 0.3 m in the lower part. The water inlet can receive the sewage that leaks out due to aging or damage of the sealing strip between the waste container and the filler during use. The sewage tank is equipped with a cylinder control or manually controlled drain valve, which facilitates the discharge of sewage at the designated place. The filler cap completely covers the filling inlet of the filler, eliminates the phenomenon of dust emission caused by the disturbance of the tail air during the transportation process, and is more beautiful;
● Electro-hydraulic joint control The car's control system makes full use of the advantages of electronic control, pneumatic control, and hydraulic control. The electronic control system controls the air control system, and then the pneumatic control system controls the hydraulic valve set, effectively solving the hydraulic system and Electrical system interface problems, make full use of the characteristics of the multi-way directional valve than the electromagnetic directional valve resistance to oil pollution, eliminate the valve stuck phenomenon, improve the use of reliability and efficiency ● Hydraulic lift safety circuit in the lift filling In the hydraulic system of the device, an explosion-proof valve is provided, which cuts off the direct connection between the lift cylinder and the hydraulic hose. Even if the fuel pipe bursts, the filler will not drop suddenly and cause a serious accident, thus improving the safety of use;
● Both automatic and manual operating systems have automatic and manual operations. For example, if the automatic operation fails, the manual operation can be used to complete the operation of the organization and unload the garbage, which ensures the high efficiency of the garbage truck and the debugging. , maintenance and troubleshooting provide great convenience;
●Automatic control of engine power output The engine power output control means that the throttle control can be fully controlled by the electrical system to meet the power requirements of the waste press fill cycle and pushing and unloading. Under other operating conditions, the engine is automatically at idle speed. Can reduce power loss and failure rate, reduce fuel consumption, improve the use of economy;
● The advanced electronic control system adopts imported PLC (programmable logic controller) integrated control. The control circuit is generated in the PLC. Logical loops are used to ensure that the operating instructions are executed in sequence. At the same time, interlock between the operating instructions is guaranteed, and only the external lines are The connection reduces the occurrence of failures, avoids accidents caused by misoperations, and improves reliability. A special emergency brake button can be used to stop the garbage compaction mechanism from stopping in any state or at any position to protect the safety of workers and equipment.
● Convenient operation and control The operation control box is installed in the cab and rear respectively. The operation control box in the cab can control the pushing and unloading and select the operation mode (such as automatic or manual). The rear operation control box controls the filling. The operation of the mechanism and the tipping mechanism is very convenient to use. Especially in landfills, operators can complete discharging and sewage discharge without getting off the train. According to the user's requirements, it can be equipped with a remote control device equipped with a line ● A variety of buckets (fighting) mechanism Different users can choose different flip bucket (bucket) mechanisms according to different garbage collection methods: turn standard waste iron bucket (300 liters), plastic Garbage can (240 liters), small rubbish bin (800 liters), sealed covered rubbish bin (1400 liters), large rubbish bin (3,350 liters); ● High quality components for the electrical and hydraulic systems of imported components Imported components, such as PLCs, proximity switches, buttons, cylinder seals, etc., improve the reliability of garbage trucks;
● Optional equipment According to user requirements, optional imported oil pump, imported multi-way reversing valve group, hydraulic oil cooler, garbage pressure filling wired remote control device.
Our factory will further improve the product. Product improvements, performance enhancements, and continuous improvement of the structure are not noticed, so there are certain instructions that do not apply to your particular vehicle. Please understand.
