[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 2-3In the embodiment of the present invention, the plastic crusher with quick knife change includes a crusher body 1 and end outer protective shells 2 arranged at both ends of the crusher body 1, and side protective shell doors 5 are provided on one side of the two end outer protective shells 2. One end of the side protective shell door 5 is rotatably connected to one of the end outer protective shells 2 through a hinge joint 6, and a rotating support 7 is connected to the side wall of the other side protective shell door 5 by screws. A locking stud 3 is movably provided on the rotating support 7, and a clamping handle 4 is connected to the outer periphery of the locking stud 3 by a thread. Two locking pressure plates 8 that cooperate with the locking stud 3 are welded on one side wall of the side protective shell door 5, and the side protective shell door 5 and the other end outer protective shell 2 are fixed to the locking pressure plate 8 through the clamping handle 4.

[0021] By adopting the above technical solution, when the blade of the plastic crusher needs to be changed, the side shell door 5 can be loosened by turning the pressing handle 4, and then the side shell door 5 is turned to expose the blade part of the crusher. The blade can be changed from the side. Compared with the existing method of changing the blade from the upper inlet, it is safer and more efficient when working while standing.

[0022] Among them, the locking stud 3 is located on one side of the rotating support 7 and is welded with a rotating shaft rotatably connected to the rotating support 7. The rotating shaft and the locking stud 3 form a T-shaped structure, which can ensure that the locking stud 3 can rotate flexibly.

[0023] Among them, a U-shaped groove for accommodating the locking stud 3 is opened at one end of the locking pressure plate 8, so as to facilitate the insertion and locking of the locking stud 3.

[0024] Among them, the two hinges of the hinged hinge 6 are connected to the side shell door 5 and the end outer shell 2 by screws, ensuring that the side shell door 5 can be flexibly opened and closed.

[0025] Example 2

[0026] like Figure 4 and Figure 5 As shown, in order to further improve the convenience of tool changing, side shell doors 5 are set at symmetrical positions on both sides of the end outer shell 2, and the two side shell doors 5 are composed of shell door 1 501 and shell door 2 502, and the shell door 1 501 and shell door 2 502 in the two side shell doors 5 are rotatably connected to the two end outer shells 2 through hinge joints 6, and the shell door 1 501 and the shell door 2 502 can be fixed with a door bolt or a lock body.

[0027] The working principle of the present invention is as follows: when the knife needs to be changed, the locking stud 3 can be separated from the locking pressure plate 8 by rotating the clamping handle 4 and then rotating the locking stud 3, and then the side shell door 5 is rotated along the hinge joint 6 to expose the knife part of the crusher, so that the knife can be changed from the side. Compared with the existing knife changing operation from the upper inlet, it is safer and more efficient to stand while working.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
