[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a lifting device for a single-shaft shredder, comprising a frame 1 and a lifting hopper 20, characterized in that: a pushing mechanism is arranged inside the lifting hopper 20, the pushing mechanism comprising a fixed shell 21, a threaded rod 22 is rotatably connected inside the fixed shell 21, a moving block 23 is threadedly connected to the threaded rod 22, a connecting block 24 is welded and fixed to the moving block 23, the connecting block 24 is slidably connected to a slide slot 28, the slide slot 28 is arranged on the fixed shell 21, a push plate 25 is welded and fixed to the front end of the connecting block 24, a through slot 27 is arranged on the inner wall of the lifting hopper 20, the through slot 27 is aligned with the slide slot 28, the fixed shell 21 is welded and fixed to the rear end of the lifting hopper 20, a motor 26 is fixed to the bottom end of the threaded rod 22, the bottom end of the threaded rod 22 is connected to the output shaft of the motor 26, and the motor 26 is welded and fixed to the fixed shell 21;

[0024] During operation, the structural design of the pushing mechanism realizes the function of pushing the materials inside the lifting hopper 20, so that some materials that are difficult to fall into the shredder by gravity can fall into the shredder smoothly under the push of the push plate 25. First, the motor 26 drives the threaded rod 22 inside the fixed shell 21 to rotate, and the moving block 23 threadedly connected to the threaded rod 22 will move on the threaded rod 22. The moving block 23 is connected to the connecting block 24, and the connecting block 24 is connected to the push plate 25. Therefore, the moving block 23 The movement of the push plate 25 can drive the push plate 25 to move inside the lifting hopper 20. At this time, when the lifting hopper 20 is lifted to the maximum height, the push plate 25 can push the material inside the lifting hopper 20 to move, ensuring that no material will remain inside the lifting hopper 20, making the lifting hopper 20 emptying more thoroughly, wherein the outer side of the push plate 25 keeps in contact with the inner wall of the lifting hopper 20 to avoid leaving a gap. When the lifting hopper 20 is emptied, the push plate 25 can move back to its original position by simply rotating the motor 26 in the opposite direction.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The bottom end of the push plate 25 abuts against the rubber strip 36, the rubber strip 36 is glued and fixed on the bottom plate 37, the bottom plate 37 is welded and fixed inside the lifting hopper 20, the push plate 25 and the bottom plate 37 are both hollowed out, the push plate 25 is trapezoidal in design, the bottom end of the push plate 25 is welded and fixed with a fixed plate 33, and the fixed plate 33 is rotatably connected with a roller 32;

[0026] During operation, the bottom plate 37 is fixed to the bottom end of the lifting hopper 20 to provide support for the bottom end of the push plate 25, and a rubber strip 36 is fixed to the bottom plate 37 to provide a buffer between the bottom end of the push plate 25 and the bottom plate 37 to prevent excessive pressure on the push plate 25 from causing greater wear between the bottom end of the push plate 25 and the bottom plate 37. The bottom ends of the push plate 25 and the bottom plate 37 are both hollowed out to reduce their own weight, and the push plate 25 is trapezoidal in design to better push the material inside the lifting hopper 20. Through the structural design of the roller 32 and the fixed plate 33, the roller 32 rotates on the push plate 25 and the fixed plate 33, so that the material on the push plate 25 can slide off the push plate 25 through the rotation of the roller 32, thereby preventing some material from staying on the push plate 25. Figure 3 The rollers 32 and rollers 32 shown in the figure are arranged in three groups, and the rollers 32 can be arranged in multiple groups according to actual conditions.

[0027] See also Figure 1 , Figure 2 , Figure 4 and Figure 5The left and right sides of the push plate 25 are both welded and fixed with a clamping block 34, and the clamping block 34 is slidably connected to the inside of the clamping slot 35. The clamping slot 35 is set on the inner wall of the lifting hopper 20. The moving block 23 is penetrated by two sets of guide rods 29. The top and bottom ends of the guide rods 29 are both welded and fixed to the inside of the fixed shell 21. The through groove 27 is provided with a groove 31. The inside of the groove 31 is slidably connected with a long strip 30. The long strip 30 is fixed to the connecting block 24 by welding, and the long strip 30 is fixed to the top of the connecting block 24.

[0028] During operation, blocks 34 are fixed on both sides of the push plate 25. When the push plate 25 moves in the lifting hopper 20, the contact between the blocks 34 and the inner wall of the slot 35 is used to ensure the stability of the push plate 25 during movement. The moving block 23 is penetrated by two sets of guide rods 29. The guide rods 29 are used to guide the movement of the moving block 23 on the threaded rod 22 to ensure the stable movement of the moving block 23. A groove 31 is also provided on the through groove 27. The long plate 30 slides in the groove 31 and the front end of the long plate 30 is kept level with the inner wall of the lifting hopper 20. The through groove 27 is sealed by the long plate 30 to prevent the material inside the lifting hopper 20 from entering the interior of the fixed shell 21 through the through groove 27 and affecting the normal operation of the threaded rod 22.

[0029] Working principle: A lifting device for a single-axis shredder in the prior art does not have a pushing structure inside the lifting hopper. When the lifting hopper moves to the top, due to the limited maximum tilt angle of the lifting hopper, it is inevitable that some materials will be difficult to fall into the shredder under the action of gravity, and stay inside the lifting hopper, resulting in incomplete material discharge. The lifting device for a single-axis shredder in this case realizes the function of pushing the material inside the lifting hopper 20 through the structural design of the pushing mechanism, so that some materials that were originally difficult to fall into the shredder by gravity can fall into the shredder smoothly under the push of the push plate 25. First, the threaded rod 22 inside the fixed shell 21 is driven to rotate by the motor 26. , the moving block 23 threadedly connected on the threaded rod 22 will move on the threaded rod 22, the moving block 23 is connected to the connecting block 24, and the connecting block 24 is connected to the push plate 25, so the movement of the moving block 23 can drive the push plate 25 to move inside the lifting hopper 20. At this time, when the lifting hopper 20 is lifted to the maximum height, the push plate 25 can push the material inside the lifting hopper 20 to move, ensuring that no material will stay inside the lifting hopper 20, so that the lifting hopper 20 can be dumped more thoroughly, wherein the outer side of the push plate 25 keeps in contact with the inner wall of the lifting hopper 20 to avoid leaving a gap. When the lifting hopper 20 is emptied, it only needs to rotate in the opposite direction by the motor 26, and the push plate 25 can move back to its original position.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
