[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figure 1 , Figure 2 ,Figure 3 and Figure 4 , the present utility model provides a technical solution: a four-axis shredder with a dust reduction function, including a base 1 and a main body 11 of the four-axis shredder. A fixing seat 12 is fixedly connected to the top of the base 1. A dust reduction component is provided between the fixing seat 12 and the main body 11. A dredging component is provided on the top of the main body 11. The dust reduction component includes a dust reduction box 21 fixedly connected to the top of the fixing seat 12, a dust suction pipe 22 fixedly connected to one side of the top of the dust reduction box 21, an air extraction pipe 23 fixedly connected to one side of the dust reduction box 21, a fan 24 connected to the air extraction pipe 23, a filter screen 25 arranged in the dust reduction box 21, a motor 26 fixedly connected to the top of the dust reduction box 21, a rotating shaft 27 fixedly connected to the output end of the motor 26, a plurality of knocking rods 28 fixedly connected to the outer side of the rotating shaft 27, and a supporting component for resetting the filter screen 25. The rotating shaft 27 is rotatably connected to the dust reduction box 21. The dust suction pipe 22 is communicated with the machine body. The main body 11 can be used to shred materials. When the fan 24 works, dust can be sucked into the dust reduction box 21 through the dust suction pipe 22, which can prevent dust from scattering and polluting the environment. The filter screen 25 can filter dust. The motor 26 can drive the rotating shaft 27 and the knocking rods 28 to rotate. The rotation of the knocking rods 28 can repeatedly knock the filter screen 25, causing the filter screen 25 to vibrate repeatedly, so that the dust on it can be shaken off, ensuring the filtering performance of the filter screen 25. The supporting component includes moving grooves 41 respectively opened on both sides inside the dust reduction box 21, moving blocks 42 respectively fixedly connected to both sides of the filter screen 25, and springs 43 fixedly connected to one side of the moving blocks 42. The moving blocks 42 are slidably connected to the moving grooves 41. The filter screen 25 can drive the moving blocks 42 to move. The movement of the moving blocks 42 can squeeze the springs 43 to deform them. When the knocking rods 28 are away from the filter screen 25, the resetting of the springs 43 can drive the filter screen 25 to reset, and thus the filter screen 25 can vibrate repeatedly, effectively cleaning the filter screen 25. A conveyor belt 61 is fixedly connected to the top of the base 1. Baffles 62 are respectively arranged on both sides above the conveyor belt 61. One side of the baffle 62 is fixedly connected to a connecting rod 63, and the connecting rod 63 is fixedly connected to the base 1. The conveyor belt 61 can conveniently transport the shredded materials away. The baffle 62 can block the materials to prevent the materials from falling off the conveyor belt 61. A feeding hopper 71 is fixedly connected to the top of the main body 11. The feeding hopper 71 is communicated with the main body 11. The feeding hopper 71 can conveniently put the materials into the main body 11, facilitating the shredding operation of the materials. An outlet hopper 81 is fixedly connected to the bottom of the main body 11. The outlet hopper 81 is located above the conveyor belt 61. The outlet hopper 81 can conveniently discharge the shredded materials onto the conveyor belt 61 for easy transportation.
[0024] Please refer to Figure 1 , Figure 2 and Figure 3, The dredging component includes a bracket 31 fixedly connected to the top of the main body 11, a cylinder 32 fixedly connected to the bottom of the bracket 31, a dredging plate 33 fixedly connected to the output end of the cylinder 32, and a plurality of dredging rods 34 arranged evenly at the bottom of the dredging plate 33. The bottom of the dredging rod 34 is conical. When the cylinder 32 works, it can push the dredging plate 33 to move vertically, and then the blocked material can be pushed into the main body 11, so as to dredge the feeding hopper 71 and prevent blockage. Compared with manual dredging, the dredging efficiency can be improved. On both sides of the top of the dredging plate 33, there are fixedly connected support rods 51 respectively. The top of the support rod 51 is fixedly connected with a limiting plate 52. The support rod 51 passes through the bracket 31 and is slidably connected with the bracket 31. The support rod 51 can guide the synchronous vertical movement of the dredging plate 33, and can guide the movement of the dredging plate 33 to prevent the dredging plate 33 from tilting.
[0025] Working principle: During operation, start the fan 24 and the main body 11, and then put the material into the main body 11 through the feeding hopper 71. Use the main body 11 to shred the material. When the fan 24 works, it can generate suction. Through the suction pipe 23 and the dust suction pipe 22, the dust can be sucked from the main body 11 into the dust settling box 21. The dust and the like are filtered by the filter screen 25 in the dust settling box 21, and the filtered air is discharged, which can prevent the environment from being polluted by dust. Then, start the motor 26. When the motor 26 works, it can drive the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, it can drive the knocking rod 28 to rotate. When the knocking rod 28 rotates, it can knock the filter screen 25. When the filter screen 25 moves, it can drive the moving block 42 to move. When the moving block 42 moves, it can squeeze the spring 43 to deform. When the knocking rod 28 moves away from the filter screen 25, the spring 43 resets and can drive the filter screen 25 to reset. Thus, the filter screen 25 can be knocked repeatedly and vibrated repeatedly, and the residual dust and the like on it can be shaken off to prevent the filter screen 25 from being blocked and ensure the filtering performance of the filter screen 25. When a blockage occurs, start the cylinder 32. When the cylinder 32 works, it can drive the dredging plate 33 to move downward. The dredging plate 33 can drive the dredging rods 34 to move downward. The dredging rods 34 can dredge the blocked material. At the same time, the dredging plate 33 can push the material from the feeding hopper 71 into the main body 11, and can quickly dredge the blocked material. The above is the working process of the whole device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
