[0022] By providing the driven shaft 6 in the inner cavity of the crushing chamber 3 and the crushing knife 10 on the outer wall of the driven shaft 6, the crushing motor 2 can drive the driven shaft 6, so that the driven shaft 6 rotates at a high speed in the inner cavity of the crushing chamber 3. During the rotation of the driven shaft 6, the material will be frictionally crushed under the action of the outer wall of the crushing knife 10 and the inner wall of the crushing chamber 3.

[0023] In a preferred embodiment: both ends of the outer wall of the electric lifting rod 8 are in contact with the outer wall of the limit seat 7 and the outer wall of the pushing plate 9 respectively, and the outer wall of the end of the connecting plate 11 away from the crushing knife 10 is rotatably connected to the outer wall of the pushing plate 9.

[0024] By arranging the crushing knife 10 on the top of the driven shaft 6, the crushing knife 10 will rotate as the driven shaft 6 rotates, so that during the rotation process, the friction crushing of the material is realized. And when the outer wall of the crushing knife 10 is worn, at this time, by adjusting the position of the pushing plate 9, the driving effect on the crushing knife 10 can be achieved, avoiding that after the outer wall of the crushing knife 10 is worn and shortened, it cannot play a role in grinding the material.

[0025] In a preferred embodiment: a limiting rod is installed on the outer wall of the crushing knife 10, a sliding groove is formed on the outer wall of the limiting plate 12, and the outer wall of the limiting rod passes through the inner cavity of the sliding groove.

[0026] By arranging the crushing knife 10 on the top of the driven shaft 6, and when the outer wall of the crushing knife 10 is worn and shortened, at this time, only need to push the pushing plate 9 downward under the action of the electric lifting rod 8, so as to drive the movement of the crushing knife 10 under the action of the connecting plate 11, so that the outer wall of the crushing knife 10 extends outward to maintain the length required for friction crushing.

[0027] In a preferred embodiment: a friction crushing plate is provided on the inner wall of the crushing bin 3, and the position of the friction crushing plate corresponds to the installation position of the crushing knife 10.

[0028] By arranging the friction crushing plate on the inner wall of the crushing bin 3, under the action of the friction crushing plate and the crushing knife 10, the material can be better ground and crushed, ensuring that the material can be crushed, and under the action of the wind force, the crushed material passes through the grading wheel 13 and enters the inner cavity of the discharge pipe 14.

[0029] In a preferred embodiment: the outer wall of one end of the connecting pipe 16 far from the discharge pipe 14 communicates with the inner cavity of the feeding pipe 15, and the outer wall of the connecting pipe 16 is inclined downward.

[0030] By arranging the filter plate 17 in the inner cavity of the discharge pipe 14 and the connecting pipe 16 on the outer wall of the discharge pipe 14, when the material enters the inner cavity of the discharge pipe 14 under the action of the wind force, the uncompletely crushed material will be blocked by the filter plate 17 and move downward along the outer wall of the connecting pipe 16, and then enter the inner cavity of the feeding pipe 15 again, and then will fall into the inner cavity of the crushing bin 3 under the action of the feeding pipe 15 and be crushed again.

[0031] In a preferred embodiment: the power output shaft of the crushing motor 2 is connected to the outer wall of the driven shaft 6 through a transmission belt. There are six crushing knives 10, and the six crushing knives 10 are evenly installed on the outer wall of the driven shaft 6.

[0032] By arranging the crushing knife 10 on the outer wall of the driven shaft 6, the driven shaft 6 will rotate at a high speed under the action of the crushing motor 2. Thus, during the rotation of the driven shaft 6, the rotation of the crushing knife 10 is driven. At this time, the material can be crushed by the action of the outer wall of the crushing knife 10 and the inner wall of the crushing chamber 3, so as to obtain the required product.

[0033] Working principle: During the use of the above equipment, when it is necessary to use the equipment to crush the material, start the crushing motor 2. Under the action of the crushing motor 2, drive the rotation of the driven shaft 6, and add the material to be crushed into the inner cavity of the feeding pipe 15, so that the material moves downward along the inner wall of the feeding pipe 15 and enters the inner cavity of the crushing chamber 3. The crushing knife 10 rotates in the inner cavity of the crushing chamber 3 under the action of the driven shaft 6. At this time, the crushing of the material can be realized under the action of the crushing knife 10 and the crushing chamber 3. After being crushed, the material will first pass through the grading wheel 13 under the action of the wind force and enter the inner cavity of the discharge pipe 14 to realize the collection of the crushed material, and the crushed material is screened again under the action of the filter plate 17, so that the larger particles cannot pass through the inner cavity of the filter plate 17 and move downward along the inner wall of the connecting pipe 16, and then enter the inner cavity of the crushing chamber 3 again through the feeding pipe 15 for crushing again. When the outer wall of the crushing knife 10 is worn and becomes short, at this time, the distance between the outer wall of the crushing knife 10 and the inner wall of the crushing chamber 3 will increase, which will affect the crushing effect. At this time, start the electric lifting rod 8. Under the action of the electric lifting rod 8, push the moving plate 9 to move. At this time, the connecting plate 11 and the crushing knife 10 can be pushed under the action of the moving plate 9. At this time, the outer wall of the crushing knife 10 moves towards the direction close to the inner wall of the crushing chamber 3, so that the distance between the outer wall of the crushing knife 10 and the inner wall of the crushing chamber 3 is shortened, thus ensuring the crushing effect of the equipment.

[0034] 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.
