Main performance and characteristics
① Electric, pneumatic and hydraulic combined control the control system of the vehicle makes comprehensive use of the advantages of electric control, pneumatic control and hydraulic control. The pneumatic control system is controlled by the electric control system, and then the hydraulic valve group is controlled by the pneumatic control system, which improves the reliability and efficiency.
② Automatic control of engine power output engine power output control, i.e. throttle control, can realize full-automatic control through the electrical system to meet the power requirements during garbage filling cycle and pushing unloading. Under other working conditions, the engine is automatically in idle state, which can reduce power loss and failure rate, reduce fuel consumption and improve use economy.
③ The frame structure dustbin adopts a solid frame structure welded by reinforcing beam and steel plate. The side and top surfaces are arc curved surfaces, with beautiful appearance, light weight, good stress and no deformation; The bulldozer is composed of steel pipe skeleton and folding panel, which not only has light structure, but also can make the garbage evenly distributed and the unloading clean and complete; The filler is mainly composed of filler shell, sliding plate, scraper and other components. Each component adopts beam plate or box structure with good stress, with firm structure and light weight.
④ Sealed treatment eliminates secondary pollution, and the waste is in a closed state during compression, loading and transportation. A special rubber sealing strip is installed on the joint surface between the dustbin and the filler, which is compressed and sealed by the locking device; A unique blowdown valve is installed on the sewage tank, which has reliable sealing and is not easy to be blocked. The optional filler cover completely covers the feeding port of the filler to eliminate the phenomenon of waste dust flying caused by the disturbance of vehicle exhaust flow during transfer, and the appearance is more beautiful.
⑤ The hydraulic lifting safety circuit is equipped with a two-way balance valve in the hydraulic system of the lifting filler. The valve not only ensures the smooth descent of the filler, but also cuts off the direct connection between the lifting oil cylinder and the hydraulic hose. Even if the oil pipe bursts, the filler will not fall suddenly, which improves the use safety.
⑥ The creeping compression function push plate valve is equipped with a special compression shovel valve. While realizing compression, the push plate can move forward automatically, so as to adjust the accommodation volume and high loading efficiency.
⑦ The oil pump of the hydraulic system of the double pump confluence technology is composed of a double pump, which realizes the confluence of the two channels of high-pressure oil in the multi-channel valve. When the bucket turnover and the loader lifting do not act, all the two channels of high-pressure oil are supplied to the filling device for work; When the bucket Tipper and the filler lift, the two channels of high-pressure oil are supplied to the corresponding devices respectively to improve the work efficiency, improve the fuel economy and reduce the transportation cost.
⑧ The advanced electric control system is controlled by Changsha Shubo controller (Zhonglian supporting) can bus. The front control adopts silica gel panel, which is stable, waterproof and durable. The rear operation box adopts button operation, which is convenient, reasonable and low maintenance cost. The logic circuit is adopted to ensure that all operation instructions are executed in sequence, and at the same time, it ensures that all operation instructions are interlocked, and there is only line connection outside, The failure rate is reduced, the accidents caused by misoperation are avoided, and the reliability is improved; The specially set emergency brake button can stop the garbage filling mechanism in any state or at any position to ensure the safety of operators and equipment.
⑨ The combination of the filler and the box adopts hydraulic mechanical locking, the sliding plate adopts nylon sliding block guide, the structure of the joint between the filler and the box is reasonable, and the hydraulic locking full sealing technology is adopted. The slide track is made of high-strength manganese steel, which is integrally bent, and the slide movement is guided by nylon slider.
⑩ The work of each mechanism of the automatic and manual operation system has two operation modes: automatic and manual. If the automatic operation fails, the mechanism operation and garbage unloading can be completed by manual operation, which not only ensures the efficient work of the garbage truck, but also provides great convenience for debugging, maintenance and fault treatment.
⑪ The convenient operation control operation control box is installed in the cab and the rear of the vehicle 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 operation control box at the rear of the vehicle controls the operation of the filling mechanism and bucket turning mechanism, which is very convenient to use and operate. Especially in the landfill, operators can complete unloading and sewage discharge without getting off the vehicle.
⑫ High quality components, key components of electrical and hydraulic systems are imported well-known components, such as controller, sensor, button, oil cylinder seal, etc., which improves the service reliability of garbage truck.
