[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The utility model provides a shredder, which comprises a shredder pushing mechanism, a feeding plate and a blade assembly. The feeding plate is arranged on one side of the blade assembly, and the shredder pushing mechanism is arranged on the feeding plate to push the material to be shredded on the feeding plate to the blade assembly for shredding.

[0025] Please refer to Figure 1 As shown, the shredder pushing mechanism includes a main body 10, a driving assembly 20 connected to the main body 10, a first supporting roller 30 and a second supporting roller 40 provided on the main body 10 for supporting the main body 10, and side blocking rollers 50 provided on the left and right sides of the main body 10. The main body 10 moves back and forth in the front and back directions driven by the driving assembly 20, that is, approaches or moves away from the blade assembly of the shredder, and the material to be shredded is crushed at the blade assembly under the push of the main body 10.

[0026] In this embodiment, the driving assembly 20 includes two linear reciprocating hydraulic cylinders, which are arranged on both sides of the main body 10. Specifically, the linear reciprocating hydraulic cylinder includes a cylinder body 21 and a piston rod 22, the cylinder body 21 is fixed to the shredder, and one end of the piston rod 22 is fixed to the main body 10. Such an arrangement simplifies the mechanical structure and improves the response speed and adjustment flexibility of the shredder's pushing mechanism. Preferably, the stroke of the linear reciprocating hydraulic cylinder is 400 to 1000 mm, which can be applied to larger materials to be processed, thereby increasing the applicability of the equipment.

[0027] Please also refer to Figure 2 As shown, the main body 10 specifically includes a top plate 11, a front plate 12, a rear plate 13, two side plates 14, a push plate group 15 arranged in front of the front plate 12, and a reinforcing plate 16 connecting the top plate 11, the front plate 12, and the rear plate 13. The width of the front plate 12 is greater than the width of the rear plate 13, that is, the front plate 12 protrudes in the left and right direction. The cylinder body 21 is fixed to the shredder, and the end of the piston rod 22 is fixed to the front plate 12. Compared with the method of fixing the piston rod 22 to the rear plate 13, the arrangement method of this embodiment enables the thrust of the linear reciprocating hydraulic cylinder to be directly applied to the front plate 12 and the push plate group 15 thereon, ensuring the smoothness and stability of the forward and backward movement of the main body 10.

[0028] The push plate group 15 includes a plurality of push plates arranged transversely, and the side of the push plate facing the forward direction of the main body 10 is concave arc-shaped, which matches the outer shape of the blade assembly (generally cylindrical), helping to improve the accuracy and efficiency of material pushing.

[0029] Please refer to Figure 2 and Figure 3 As shown, the first support roller 30 is disposed at the rear end of the main body 10. There are two first support rollers 30, which are respectively disposed on the rear side of the rear plate 13 and close to the left and right ends. The first support roller 30 includes a mounting frame 31, a roller shaft 32 and a roller 33. The mounting frame 31 is fixed to the rear side of the rear plate 13, and the roller shaft 32 is arranged along the left and right directions. In this embodiment, a round table 331 is provided on the side of the roller 33 close to the main body 10. When the shredder pushing mechanism is installed on the shredder, the roller 33 cooperates with the track on the shredder. Please refer to the schematic diagram of the track for details. Figure 2 When the roller 33 moves above the track, the round table 331 is located on one side of the track to limit the roller 33, thereby playing a certain guiding role for the main body 10. In addition, guide grooves 17 are provided on both side edges of the front plate 12, and the guide grooves 17 are used for the track to pass through. Through the cooperation of the guide grooves 17, the track and the roller 33, the main body 10 is further limited to prevent the main body 10 from being displaced in the left-right direction and the up-down direction.

[0030] Please refer to Figure 1 and Figure 4As shown, the second support roller 40 is disposed at the front end of the main body 10. The second support roller 40 includes a mounting frame 41, a roller shaft 42 and a roller 43. The roller shaft 42 is arranged along the left-right direction. In this embodiment, a plurality of reinforcing plates 16 are arranged along the left-right direction. Preferably, the number of reinforcing plates 16 is 4, which are divided into two groups and symmetrically distributed between the two side plates 14. Since the height of the rear plate 13 is less than the height of the front plate 12, the reinforcing plate 16 is roughly in the shape of a right-angled trapezoid, and the second support roller 40 is disposed at the acute angle of the trapezoidal reinforcing plate 16, that is, the second support roller 40 is located below the main body 10 and close to the front end.

[0031] Please refer to Figure 1 and Figure 5 As shown, the side roller 50 includes a mounting frame 51, a roller shaft 52 and a roller 53, and the roller shaft 52 is arranged in the up-down direction. There are two side rollers 50, which are arranged on both sides of the main body 10 near the front end. Specifically, the mounting frame 51 is arranged on the rear side of the front plate 12, and the side roller 50 is approximately located below the fixed end of the piston rod 22. The arrangement of the side roller 50 helps prevent the lateral deviation of the material during the pushing process.
