[0043] Among them, the corn stalks to be crushed are sent into the interior of the crushing cylinder 1, and the guide wheel 33 is driven to rotate by the motor 32, so that the rotating column 2 can be driven to rotate through the pulley 31, and the stalks entering the crushing cylinder 1 can be quickly cut and crushed by the rotation of the crushing knife 3 and the hammer knife 4. The rapid rotation of the hammer knife 4 forces the cut and crushed materials to generate centrifugal force and be thrown out of the crushing cylinder 1 into the discharge channel 6 to complete the unloading work.

[0044] The separation mechanism 9 includes a dial 901 and a pick column 902. The dial 901 is rotatably connected to the inside of the discharge channel 6, and the dial 901 is rotatably connected to the top of the sieve plate 7. The pick column 902 is rotatably connected to the inside of the collection box 8. A plurality of ladle heads 14 are evenly arranged on the surface of the dial 901. A plurality of scraper arms 15 are evenly arranged on the surface of the pick column 902. Two adjacent scraper arms 15 are slidably connected to the two sides of one of the ladle heads 14. A top block 16 is slidably connected to the inside of the dial 901. Two top heads 17 are symmetrically hinged on the two sides of the surface of the top block 16. A cutter 18 is hinged on the other end of the top head 17. The two cutters 18 are symmetrically slidably connected to the inside of the dial 901. The cutter 18 and the dial 901 are arranged through. The other end of the top block 16 penetrates into the inside of the dial 901 and is fixedly connected to a push rod 19. A spring 20 is fixedly connected to one side of the push rod 19. The other end of the spring 20 is fixedly connected to the inside of the dial 901.

The guide tooth 132 is rotatably connected between the two disc teeth 131, and the two sides of the guide tooth 132 are respectively meshed with the two disc teeth 131, one of the disc teeth 131 is fixedly connected to one end of the dial wheel 901, and the other disc tooth 131 is fixedly connected to one end of the picking column 902.

[0045] The rotation of the guide wheel 33 drives the driven wheel 35 to rotate, which can drive the thumbwheel 901 to rotate. The thumbwheel 901 drives the ladle 14 to rotate, so that the material flowing through the discharge channel 6 can be stirred and the strip materials mixed therein can be removed. When the connecting column 34 and the thumbwheel 901 rotate, one of the disc teeth 131 will be driven to rotate. Since the two sides of the guide tooth 132 rotate with the two disc teeth 131 respectively, the other disc tooth 131 will produce a rotation effect in the same direction as the disc teeth 131 on the surface of the connecting column 34. At this time, the thumbwheel 901 and the picking column 902 rotate synchronously, and the removed strip materials can be pushed into the collection box 8 through the sliding effect between the two adjacent scraping arms 15 and the ladle 14. In the process of the picking column 902 rotating close to the scraping arm 15, one of the top rods 19 will slide with the top column 21 and be forced to move toward The push rod 19 slides in the direction of the picking column 902. At this time, the push head 17 can be pushed by the top block 16 through the hinge effect, so that parts of the two cutters 18 are pushed out of the two sides of the picking column 902. Through the sliding effect between the lapel head 14 and the scraper arm 15, the cutter 18 can cut the rejected strip materials, thereby achieving the working effect of pre-crushing the strip materials that do not meet the production particle size, and achieving the working effect of automatically rejecting the strip materials in the material; and with the contact and sliding between the push rod 19 and the top column 21, during the rotation of the dial wheel 901, the cutter 18 will always remain in an extended state. At this time, the cutter 18 can push the material above the screen plate 7 during the rotation of the lapel head 14, which can effectively prevent material accumulation, and ensure that the material that does not meet the particle size requirements inside the material is thoroughly rejected to prevent material residue.

[0046] The shaking screen mechanism 10 is arranged on one side of the discharge channel 6. The shaking screen mechanism 10 is used to drive the screen plate 7 to slide.

A connecting rod 37 is fixedly connected to the side of the screen plate 7 away from the L-shaped rocker arm 103, and the connecting rod 37 is slidably connected to the discharge channel 6 through the connecting groove 36.

[0047] Among them, the rotation of the thumbwheel 901 drives the rotating gear 101 to rotate, and the meshing effect drives the meshing gear 102 to rotate, thereby driving the L-shaped rocker arm 103 to slide inside the discharge channel 6, and the L-shaped rocker arm 103 drives the screen plate 7 to slide rapidly back and forth along the connecting groove 36. On the one hand, the blocking effect of the screen plate 7 can slow down the falling speed of the material, ensuring that the ladle 14 can thoroughly remove the accumulated material. On the other hand, the fast sliding screen plate 7 can ensure that the material passes through the screen plate 7 normally, ensuring the normal unloading work.

[0048] A feeding mechanism 11 is provided at one side of the crushing cylinder 1. The feeding mechanism 11 is used to transport the materials sorted by the separation mechanism 9. The feeding mechanism 11 includes a vertical cylinder 111, a guide roller 112 and a lifting roller 113. The vertical cylinder 111 is fixedly connected to one side of the crushing cylinder 1, and one end of the vertical cylinder 111 is communicated with one side of the collecting box 8. The guide roller 112 is rotatably connected to the inside of the collecting box 8. A chute 24 is provided inside the collecting box 8. One end of the chute 24 is communicated with the discharge channel 6, and the other end of the chute 24 extends to the bottom of the guide roller 112. The lifting roller 113 is rotatably connected to the inside of the vertical cylinder 111. A driver 25 is fixedly connected to the top of the vertical cylinder 111.

The inclined slot 26 is located at the bottom of the guide roller 112, and the other end of the inclined slot 26 is connected to the vertical cylinder 111. The pushing mechanism 12 is connected, and the pushing mechanism 12 is arranged on one side of the crushing cylinder 1, and the pushing mechanism 12 is arranged on the top of the feeding mechanism 11. The pushing mechanism 12 is used to push the material conveyed by the feeding mechanism 11 into the crushing cylinder 1 for re-crushing. The pushing mechanism 12 includes a connecting cylinder 121 and a pushing roller 122. The connecting cylinder 121 is connected to one side of the crushing cylinder 1, and the pushing roller 122 is rotatably connected to the inside of the crushing cylinder 1. One side of the surface of the vertical cylinder 111 is fixedly connected with a connecting box 27, and the other end of the connecting box 27 is fixedly connected to the top of the connecting cylinder 1. The vertical cylinder 111 and the connecting cylinder 121 are connected by the connecting box 27.

The other end of the guide column 29 passes through one end of the outside of the crushing cylinder 1 and is fixedly connected with a rotating wheel 30. The rotating wheel 30 and the connecting wheel 28 are connected by a belt drive.

[0049] Among them, the material entering the collection box 8 will slide to the guide roller 112 through the chute 24, and the guide roller 112 will be driven to rotate by the motor 32 to transport the rejected material into the vertical cylinder 111. In this process, the diversion effect of the inclined slot 26 can ensure that the material can be smoothly transported to the vertical cylinder 111 to prevent residue. The lifting roller 113 is driven to rotate by the driver 25, so that the material in the vertical cylinder 111 can be lifted upward and finally flow into the connecting cylinder 121 through the connecting box 27. The rotating column 2 will drive the rotating wheel 30 to rotate while rotating, thereby driving the connecting wheel 28 to rotate through the transmission effect of the belt. At this time, the pushing roller 122 rotates with the connecting wheel 28, so as to push the material flowing in through the connecting box 27 into the inside of the crushing cylinder 1 for re-cutting and crushing, which can further improve the material yield.

[0050] The specific working principle and use method of the present invention are explained in detail below: When in use, the first step is to feed the corn stalks to be crushed into the interior of the crushing cylinder 1, and the guide wheel 33 is driven to rotate by the motor 32, so that the rotating column 2 can be driven to rotate by the pulley 31, and the stalks entering the crushing cylinder 1 can be quickly cut and crushed by the rotation of the crushing knife 3 and the hammer knife 4, and the rapid rotation of the hammer knife 4 forces the cut and crushed materials to generate centrifugal force and be thrown out of the crushing cylinder 1 into the discharge channel 6 to complete the unloading work;

[0051] In the second step, the rotation of the guide wheel 33 drives the driven wheel 35 to rotate, which can drive the thumbwheel 901 to rotate. The thumbwheel 901 drives the lapel head 14 to rotate, so as to stir the material flowing through the discharge channel 6 and remove the strip materials mixed therein. When the connecting column 34 and the thumbwheel 901 rotate, one of the disc teeth 131 will be driven to rotate. Since the two sides of the guide tooth 132 rotate with the two disc teeth 131 respectively, the other disc tooth 131 will produce a rotation effect in the same direction as the disc teeth 131 on the surface of the connecting column 34. At this time, the thumbwheel 901 and the removal column 902 rotate synchronously. Through the sliding effect between the lapel head 14 and the scraper arm 15, the removed strip materials can be cut off in cooperation with the cutter 18, and the removed strip materials can be pushed into the collection box 8 through the sliding effect between the two adjacent scraper arms 15 and the lapel head 14.

[0052] In the third step, the material entering the collection box 8 will slide to the guide roller 112 through the chute 24, and the guide roller 112 will be driven to rotate by the motor 32 to transport the rejected material into the vertical cylinder 111. In this process, the diversion effect of the chute 26 can ensure that the material can be smoothly transported to the vertical cylinder 111 to prevent residue. The lifting roller 113 is driven to rotate by the driver 25 to lift the material in the vertical cylinder 111 upward and finally flow into the connecting cylinder 121 through the connecting box 27. The rotating column 2 will drive the rotating wheel 30 to rotate while rotating, thereby driving the connecting wheel 28 to rotate through the transmission effect of the belt. At this time, the pushing roller 122 rotates with the connecting wheel 28, so as to push the material flowing in through the connecting box 27 into the inside of the crushing cylinder 1 for re-cutting and crushing.

[0053] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
