Through this design, when using the V-shaped blade structure of this plastic crusher, after installing the first blade 214 and the second blade 215 on the mounting seat 212, rotate the rotating shaft 111 to drive the mounting seat 212 to rotate synchronously, and then drive the first blade 214 and the second blade 215 to rotate synchronously to stir and crush the material. During the stirring and crushing process, the two groups of second blades 215 are arranged in an inclined shape. While stirring the material, they will not disperse the material to both sides, but gather the material to the contact area of the two groups of second blades 215, avoiding the dispersion of the material during the stirring process and making it difficult to break, and improving the crushing effect.

[0023] Further, an installation hole 216 is opened inside the first blade 214, and the installation hole 216 is opened inside the mounting seat 212 and the second blade 215. An installation bolt 217 is installed inside the installation hole 216. Through this design, both the first blade 214 and the second blade 215 are installed on the mounting seat 212 by using the installation hole 216 and the installation bolt 217. The operation is simple and the installation is firm, which is convenient for disassembly, replacement and maintenance.

[0024] Further, an external thread is arranged on the outer wall of the rotating shaft 111, an internal thread is arranged on the inner wall of the baffle 211, and the baffle 211 is installed on the rotating shaft 111 by threads.

[0025] Further, the disassembly and assembly mechanism 3 includes a mounting block 311, the mounting block 311 is fixedly connected to the outer wall of the stirring plate 213, the mounting block 311 is inserted into an installation groove 312, the installation groove 312 is opened inside the mounting seat 212, a plug rod 313 is inserted into the mounting block 311, the plug rod 313 can slide inside the mounting seat 212, and one end of the plug rod 313 away from the mounting block 311 is inserted into a plug cavity 315, the plug cavity 315 is opened inside the mounting seat 212. Through this design, when using the V-shaped blade structure of this plastic crusher, when the rotating shaft 111 drives the mounting seat 212 to rotate, the stirring plate 213 is used to assist in stirring the material. When it needs to be disassembled and assembled, the pull rod 314 can be pulled to drive the plug rod 313 to move away from the mounting block 311, so that the plug rod 313 moves out of the mounting block 311, and then the stirring plate 213 is pulled to drive the mounting block 311 to move out of the installation groove 312, and then the stirring plate 213 can be conveniently disassembled and assembled.

[0026] Furthermore, one end of the rod 313 away from the mounting block 311 is fixedly connected to a spring 316, and the other end of the spring 316 away from the rod 313 is fixedly connected to the inner wall of the insertion cavity 315. Through this design, when installing the stirring plate 213, the pull rod 314 can be pulled to drive the rod 313 to move in a direction away from the mounting block 311, and then the stirring plate 213 is installed to the outside of the mounting seat 212, and the mounting block 311 enters the mounting groove 312. At this time, the spring 316 is in a compressed and force-accumulating state, and the pull rod 314 is released. The elastic force of the spring 316 can automatically drive the rod 313 to enter the mounting block 311, and the installation limit is performed, so that the assembly of the stirring plate 213 can be completed conveniently.

[0027] Furthermore, a slider 317 is fixedly connected to the side wall of the insertion rod 313, and the slider 317 is slidably set inside the slide groove 318. The slide groove 318 is opened inside the mounting seat 212. Through this design, when the insertion rod 313 moves, the slider 317 moves synchronously inside the slide groove 318, thereby realizing the limiting effect on the insertion rod 313, making its movement more stable.

[0028] Working principle:

[0029] When using the V-shaped blade structure of the plastic crusher, after installing the first blade 214 and the second blade 215 on the mounting seat 212, rotate the rotating shaft 111 to drive the mounting seat 212 to rotate synchronously, thereby driving the first blade 214 and the second blade 215 to rotate synchronously, so that they stir and crush the materials. During the stirring and crushing process, the two groups of second blades 215 are arranged in an inclined shape. While stirring the materials, they will not disperse the materials to both sides, but gather the materials to the contact area of the two groups of second blades 215, so as to avoid the dispersion of the materials during the stirring process and make them difficult to crush, thereby improving the crushing effect.

[0030] When the V-shaped blade structure of the plastic crusher is used, when the rotating shaft 111 drives the mounting seat 212 to rotate, the stirring plate 213 is used to assist in stirring the material. When it is necessary to disassemble it, the pull rod 314 can be pulled to drive the insertion rod 313 to move away from the mounting block 311, so that the insertion rod 313 is moved out of the mounting block 311, and then the stirring plate 213 is pulled to drive the mounting block 311 to move out of the mounting groove 312, so that the stirring plate 213 can be easily disassembled and assembled. During installation, the pull rod 314 can be pulled to drive the insertion rod 313 to move away from the mounting block 311, and then the stirring plate 213 is installed to the outside of the mounting seat 212, and the mounting block 311 enters the inside of the mounting groove 312. At this time, the spring 316 is in a compressed and force-storing state, and the pull rod 314 is released. The elastic force of the spring 316 can automatically drive the insertion rod 313 to enter the inside of the mounting block 311, and the installation is limited. The assembly of the stirring plate 213 can be completed conveniently, and the operation is completed.

[0031] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to the illustrations in the specification and the above description; however, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are equivalent embodiments of the present utility model; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
