DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a crusher with a material discharging anti-blocking structure, comprising a body 1, a bracket 3 is fixedly connected to the surface of the body 1, a motor 4 is fixedly connected to the inner side of the bracket 3, a crushing shaft 5 is fixedly connected to the output shaft of the motor 4, the crushing shaft 5 passes through the body 1 and is rotatably connected, the crushing shaft 5 passes through and is fixedly connected to a crushing roller 6, the crushing shaft 5 passes through and is fixedly connected to a gear 7, and a control part 2 is provided on the top of the body 1 to prevent blocking during material discharging, and the control part 2 comprises: a hopper 21, a chassis 22, a motor 23, a rotating shaft 24, a gear shaft 25, a linkage column 26, a stabilizing frame 27, a crushing knife 28, a conical block 29, a dial plate 210, a baffle 211, a connecting plate 212, a ramp block 213, a resisting rod 214, a rotating ring 215, and a spring 216.

[0022] The feed hopper 21 penetrates the top surface of the body 1 and is fixedly connected. The top surface of the feed hopper 21 is fixedly connected to a chassis 22. The inner wall of the chassis 22 is fixedly connected to a motor 23. The output shaft of the motor 23 is fixedly connected to a rotating shaft 24. The rotating shaft 24 penetrates the body 1 and is rotatably connected. The bottom surface of the rotating shaft 24 is fixedly connected to a gear shaft 25. The bottom end of the gear shaft 25 penetrates and is slidably connected to a linkage column 26. Start the motor 23 so that the motor 23 drives the rotating shaft 24 to rotate, and pour the wood blocks into the hopper 21. When the output shaft of the motor 23 drives the rotating shaft 24 to rotate, it will drive the gear shaft 25 to rotate together, and then the gear shaft 25 drives the penetrating linkage column 26 to rotate together. The inner wall of the body 1 is fixedly connected to a stabilizing frame 27, and the linkage column 26 penetrates the stabilizing frame 27. The control unit 2 also includes a crushing knife 28. When the linkage column 26 keeps rotating, the resistance rod 214 repeatedly resists the inclined block 213, so that the linkage column 26 can reciprocate up and down while rotating, so that the linkage column 26 drives the crushing knife 28 located at the bottom of the feed hopper 21 to rotate and crush the wood blocks up and down, so that the crushing knife 28 can perform preliminary crushing on the wood blocks to avoid clogging of the feed hopper 21.

[0023] The crushing knife 28 is fixedly connected to the surface of the linkage column 26, and the linkage column 26 is penetrated and fixedly connected with a cone block 29, and the top surface of the cone block 29 is fixedly connected with a dial plate 210. The inner wall of the hopper 21 is fixedly connected with a baffle 211, and the top of the linkage column 26 is penetrated and fixedly connected with a connecting plate 212, and the top surface of the connecting plate 212 is fixedly connected with an inclined surface block 213. When the output shaft of the motor 23 drives the rotating shaft 24 to rotate, it will drive the gear shaft 25 to rotate together, and then the gear shaft 25 drives the linkage column 26 that penetrates to rotate together. At this time, the linkage column 26 is located in the stable frame 27 and rotates, and the rotation of the linkage column 26 drives the connecting plate 212 to rotate together, so that when the connecting plate 212 rotates, it drives the inclined surface block 213 to rotate together. The inner wall of the hopper 21 is fixedly connected with a resistance rod 214, and the bottom end of the resistance rod 214 is semicircular. When the inclined plane block 213 rotates, the inclined plane of the inclined plane block 213 gradually resists the semicircular bottom end of the resistance rod 214, so that the inclined plane block 213 is forced to push the connecting plate 212 to move downward, so that the connecting plate 212 pushes the linkage column 26 to move downward together, and the rotating ring 215 will move downward together with the linkage column 26. The top surface of the linkage column 26 is penetrated by the rotating ring 215, and the rotating ring 215 is rotatably connected with the linkage column 26. The top surface of the rotating ring 215 is fixedly connected with a spring 216. The connecting plate 212 pushes the linkage column 26 to move downward together, and the rotating ring 215 will move downward together with the linkage column 26 and tighten the spring 216. After the inclined plane block 213 rotates a certain distance, the contact rod 214 exceeds the highest point of the inclined plane block 213, and the tightened spring 216 will pull the linkage column 26 back through the rotating ring 215. The end of the spring 216 away from the rotating ring 215 is fixedly connected to the inner wall of the feed hopper 21. There are two groups of crushing shafts 5, and the gears 7 penetrated by the two groups of crushing shafts 5 are meshed with each other. When crushing the wood blocks used for the production of density fiberboard, the motor 4 is started first, and the output shaft of the motor 4 will drive the crushing roller 6 and the gear 7 to rotate through the crushing shaft 5, and through the meshing gear 7, the crushing rollers 6 penetrated by the two groups of crushing shafts 5 rotate together.

[0024] Based on the above embodiment, when the wood blocks for density fiberboard production are crushed, the motor 1 4 is started first, and the output shaft of the motor 1 4 drives the crushing roller 6 and the gear 7 to rotate through the crushing shaft 5, and through the meshing gear 7, the crushing rollers 6 penetrated by the two sets of crushing shafts 5 rotate together, and then the motor 2 23 is started, so that the motor 23 drives the rotating shaft 24 to rotate, and the wood blocks are poured into the hopper 21. When the output shaft of the motor 23 drives the rotating shaft 24 to rotate, it drives the gear shaft 25 to rotate together, and then the gear shaft 25 drives the linkage column 26 penetrated by it to rotate together. At this time, the linkage column 26 is located in the stable frame 27 and rotates. The rotation of the linkage column 26 drives the connecting plate 212 to rotate together, so that the connecting plate 212 drives the inclined surface block 213 to rotate together when rotating, and when the inclined surface block 213 rotates, the inclined surface of the inclined surface block 213 gradually contacts the bottom semicircular end of the contact rod 214. The inclined plane block 213 is forced to push the connecting plate 212 to move downward, so that the connecting plate 212 pushes the linkage column 26 to move downward together, and the rotating ring 215 will move downward together with the linkage column 26 and tighten the spring 216. After the inclined plane block 213 rotates a certain distance, the abutment rod 214 exceeds the highest point of the inclined plane block 213, and the tightened spring 216 will pull the linkage column 26 back through the rotating ring 215. When the linkage column 26 keeps rotating, the abutment rod 214 repeatedly abuts the inclined plane block 213, so that the linkage column 26 will reciprocate up and down while rotating, so that the linkage column 26 drives the crushing knife 28 located at the bottom of the feed hopper 21 to rotate and crush, and also flip the wood block up and down, so that the crushing knife 28 performs preliminary crushing on the wood block to avoid clogging of the feed hopper 21, and the up and down flipping can prevent blockage during feeding, and multi-stage crushing can also prevent blockage when the crushed wood is discharged.

[0025] When the linkage column 26 rotates and reciprocates up and down, it also drives the conical block 29 to rotate and pound the feeding port of the feeding hopper 21 up and down to prevent the wood blocks from getting stuck in the feeding hopper 21, so that the wood blocks can pass more efficiently and be crushed in multiple stages.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
