The power of the high-pressure gear pump 42 is driven by a dedicated motor 41 for the oil pump to realize the function of heavy-load operation.

[0022] like Figure 4 and Figure 5As shown, a cylinder fixing seat 12 is provided at the bottom center of the lifting slide frame 1, and the hydraulic drive device 4 also includes a vertical cylinder 43 connected to the cylinder fixing seat 12; the top of the piston rod of the cylinder 43 is fixedly connected to the lifting shaft 44, and sprockets 45 are symmetrically arranged at both ends of the lifting shaft 44 through bearings. The upper end of the chain 46 passes through the sprocket 45 and is connected to the lifting slide frame 1 through the chain tensioning mechanism 13, and the lower end of the chain 46 is connected to the lifting frame 2 through the chain tensioning mechanism 13. The lifting shaft 44 of the hydraulic drive device 4 is connected to the lifting frame 2 through the chain 46, and then the lifting and flipping frame 3 is driven to rise along the lifting part of the slide 11 through the lifting frame 2, and flipped at the flipping part of the slide 11. Among them, the chain tensioning mechanism 13 is a prior art and can be purchased from outside. It has a spring inside to ensure that the chain 46 is always in a tensioned state.

[0023] like Figure 5 As shown, damping devices 14 are symmetrically arranged on both sides of the top of the lifting slide frame 1; a pressure plate 23 is provided at the lower end of the rear surface of the lifting frame 2. When the lifting frame 2 is lifted to the top limit position, the pressure plate 23 contacts the damping device 14. The damping device 14 can achieve the functions of shock absorption and reset. On the one hand, it can make the hopper car 34 slowly turn over before reaching the limit position. On the other hand, it can turn over and reset the lifting and turning frame 3 whose center of gravity has been shifted after dumping the material, and then descend to the initial position together with the lifting frame 2.

[0025] like Figure 2 As shown, the lifting and turning frame 3 includes a split structure of a turning bracket 33 and a hopper car 34. The bottom pulley of the hopper car 34 can be directly pushed into the turning bracket 33, reducing the cumbersome process of dumping materials. A locking mechanism 35 is provided on the turning bracket 33. The hopper car 34 is supported on the turning bracket 33 and locked on the turning bracket 33 through the locking mechanism 35. In this embodiment, the locking mechanism 35 adopts a rotating card plate structure. When the card plate is raised and locked, the hopper car 34 can be prevented from sliding out. At the same time, the turning bracket 33 also adopts a limiting beam located at the top of the hopper car 34 to prevent the hopper car 34 from being separated from the turning bracket 33 during the turning process.

[0026] A material guide trough 36 is provided at the rear end of the tipping bracket 33. One end of the material guide trough 36 surrounds the upper opening of the hopper car 34, and the other end is tilted backward. During the tipping process of the hopper car 34, there is a certain distance between the opening and the material receiving port, and the material guide trough 36 is used to prevent material from overflowing.
