[0032] The working principle and beneficial technical effects of the above technical solution are as follows: starting the motor 18 drives the first gear 19 to rotate, and the first gear 19 and the second gear 22 are meshed, so that the first gear 19 and the second gear 22 rotate in opposite directions, which correspondingly drives the two crushing teeth 10 to rotate in opposite directions to crush the waste.

[0033] In one embodiment, Figure 1-5 As shown, the material-dispensing rod driving assembly includes: a third gear 23 and a fourth gear 24. The inner wall of the box body 17 is rotatably connected with the third gear 23 and the fourth gear 24. The diameter of the third gear 23 is greater than the diameter of the fourth gear 24. The third gear 23 is meshed with the first gear 19 and the fourth gear 24 respectively. The third gear 23 is provided with a first eccentric column 25, and the fourth gear 24 is provided with a second eccentric column 26. A vertical slide 27 is provided on the side wall of the crushing box 1 above the fourth gear 24. The slide 27 A slider 28 is slidably connected inside, a third shaft 29 passes through the slider 28 and is rotatably connected to the slider 28, one end of the third shaft 29 extends into the crushing box 1 and is connected to the material-dispensing rod 11, the other end of the third shaft 29 extends into the box body 17 and is connected to the middle of a rocker 30, one end of the rocker 30 is hinged to one end of a first connecting rod 31, the other end of the first connecting rod 31 is rotatably connected to the first eccentric column 25, the other end of the rocker 30 is hinged to one end of a second connecting rod 32, the other end of the second connecting rod 32 is rotatably connected to the second eccentric column 26.

[0034] The working principle and beneficial technical effects of the above technical solution are as follows: the first gear 19 rotates, and the first gear 19 and the third gear 23 are meshed, driving the third gear 23 to rotate, and the third gear 23 is meshed with the fourth gear 24. Since the diameters of the third gear 23 and the fourth gear 24 are different, the third gear 23 and the fourth gear 24 rotate in opposite directions at different speeds, driving the first eccentric column 25 and the second eccentric column 26 to rotate in opposite directions at different speeds. The distance and position of the first eccentric column 25 and the second eccentric column 26 are constantly changed, driving the first connecting rod 31 and the second connecting rod 32 to move. , driving the rocker 30 to swing up and down around the axis of the third rotating shaft 29, and driving the slider 28 to swing back and forth along the slide 27 at the same time. The rocker 30 and the material-pickup rod 11 are vertical and fixedly connected through the third rotating shaft 29. The rocker 30 drives the material-pickup rod 11 to swing back and forth around the axis of the third rotating shaft 29, and moves back and forth up and down with the slider 28. On the one hand, the solid waste above the two crushing teeth 10 is sent into the two crushing teeth 10 for crushing. The left and right swinging of the material-pickup rod 11 can also play a role in guiding the material, preventing the waste from clogging above the crushing teeth 10 and affecting the crushing efficiency of the waste. There is a linkage relationship between the crushing teeth 10 and the material-pickup rod 11. When the amount of waste is large, increasing the speed of the motor 18 will increase the speed of the two crushing teeth 10 rotating in opposite directions. Correspondingly, the frequency of the left and right swinging of the material-pickup rod 11 and the frequency of the up and down reciprocating vibration will also increase, so that more waste can be guided, so as to quickly process more waste and prevent a large amount of waste from accumulating on the top of the crushing box 1.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
