[0029] Referring to Figure 1 、 Figure 3 With Figure 5 , the inside of the body 1 above the partition plate 2 is provided with a cleaning mechanism 4, the cleaning mechanism 4 includes an electric track 41, the electric track 41 is fixedly connected with the inner wall of the body 1, the mover of the electric track 41 can slide back and forth inside the electric track 41, and this technology is prior art, which can be realized by those skilled in the art, so in this case, it is not described in detail, the mover of the electric track 41 is fixedly connected with a sliding block 42, the outer wall of the sliding block 42 is slidingly connected with a scraper 43, the sliding direction of the scraper 43 relative to the sliding block 42 is upward and downward sliding, the material of the scraper 43 is set to be silica gel, the cleaning mechanism 4 further includes a control groove 44, the shape of the control groove 44 is a parallelogram, and the depth of the left side of the upper horizontal part of the control groove 44 is deeper than the right side, and the left side of the upper horizontal part of the control groove 44 is set as an inclined surface.
[0030] Referring to Figure 5 With Figure 6 , the inside of the scraper 43 and the inside of the control groove 44 are jointly provided with a control assembly 45, the control assembly 45 includes a sliding groove 451, the sliding groove 451 is opened in the inner wall of the scraper 43, the inner wall of the sliding groove 451 is slidingly connected with a limiting block 452, the width of the limiting block 452 is matched with the width of the control groove 44, the right end of the limiting block 452 is elastically connected with the inner wall of the sliding groove 451 through a spring 453, one end of the spring 453 is fixedly connected with the right end of the limiting block 452, and the other end of the spring 453 is fixedly connected with the inner wall of the sliding groove 451, through the setting of the spring 453, it is ensured that the limiting block 452 cannot directly escape from the deeper position without external force after moving to the deeper position of the control groove 44.
[0031] Working principle: in use, since the electric track 41 is in the starting state in the process of producing the tooth shaft, the electric track 41 drives the sliding block 42 to move back and forth in the front and rear directions, and when the sliding block 42 moves, the scraper 43 is driven to move back and forth.
[0032] When the scraper 43 moves from back to front, the limiting block 452 is in the lower area of the control groove 44, so at this time the scraper 43 can push the waste above the partition plate 2 from back to front, so that it enters the discharge chute 6.
[0033] When the scraper 43 moves and the limiting block 452 is in the inclined area in front of the control groove 44, at this time the scraper 43 is subjected to a force moving forward, and because the limiting block 452 is inside the control groove 44, at this time the scraper 43 is inclined and moves upward under the driving of the limiting block 452.
[0034] When the limiting block 452 moves to the front upper position of the control groove 44, the depth of the position is deep, so at this time the limiting block 452 moves to the direction of entering the deep part of the control groove 44 under the elastic force of the spring 453, so that the limiting block 452 cannot directly move downward because it enters the deep position of the control groove 44, so at this time when the scraper 43 is moved backward by the slider 42, the limiting block 452 is in the upper position of the control groove 44, so that the bottom end of the scraper 43 does not contact the partition plate 2 during the movement from front to back, so at this time it does not contact the debris on the upper surface of the partition plate 2.
[0035] When the scraper 43 moves from front to back to the inclined part behind the limiting block 452 entering the control groove 44, the limiting block 452 moves to the right lower side along the inclined position of the control groove 44, and when it moves to the right lower position, when the scraper 43 is moved forward by the slider 42, because of the gravity of the scraper 43, there is no upward moving force under the premise of no other force, so the limiting block 452 moves forward along the lower side of the control groove 44, so when moving from back to front, the scraper 43 can scrape the debris attached to the partition plate 2.
[0036] When the debris enters the discharge chute 6, it moves downward along the inclined surface of the discharge chute 6 and enters the inside of the receiving frame 36.
[0037] At this time, the motor 32 is started, so the motor 32 drives the rotating rod 33 to rotate, and the rotating rod 33 drives the gear three 384 to rotate, so the gear three 384 drives the gear one 382 to rotate.
[0038] When the gear one 382 rotates, the gear one 382 drives the rotating rod 381 to rotate, so the rotating rod 381 drives the gear two 383 to rotate, and then the gear two 383 drives the gear four 385 to rotate, so that the rotating pipe 34 rotates.
[0039] Because the gear one 382 and the gear two 383 are coaxially arranged, the angular velocities of the gear one 382 and the gear two 383 are the same, because the gear one 382 and the gear three 384 are engaged, the linear velocities of the gear one 382 and the gear three 384 are the same, because the gear two 383 and the gear four 385 are engaged, the linear velocities of the gear two 383 and the gear four 385 are also the same, because the gear number ratio of the gear one 382 and the gear three 384 and the gear number ratio of the gear two 383 and the gear four 385 are different, so when the gear one 382 and the gear two 383 rotate by the same angle, they drive the gear three 384 and the gear four 385 to rotate by different angles, so the gear three 384 and the gear four 385 rotate in the same direction, but the rotating speeds are different.
[0040] The gear four 385 drives the rotating pipe 34 to rotate, and drives the push plate 35 to rotate through the rotating pipe 34, and the material receiving frame 36 is driven to rotate by the rotating rod 33, so that the material receiving frame 36 and the push plate 35 rotate at different speeds, and the waste falling above the material receiving frame 36 can fall into the inside of the collecting frame 5 under the pushing of the push plate 35 when the discharging port 37 is at different positions, so that the falling waste is dispersed, the actual use rate of the collecting frame 5 is increased, the collecting frame 5 can be used for a longer time, and the working efficiency is improved.
[0041] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
