One of the pulverizing rollers 503 is fixedly connected with the output shaft of the second motor 502. The number of the gears 504 is two. The gears 504 are fixedly connected with the rotating shaft surfaces of the pulverizing rollers 503 respectively. The two gears 504 are meshed with each other. The discharge pipe 505 is located below the box 501. The top end of the discharge pipe 505 is in communication with the inside of the box 501. The bottom end of the discharge pipe 505 extends into the inside of the shell 1.

[0039] The inner wall of the box body 501 is fixedly connected with baffles on both sides of the crushing roller 503, and the rotating shaft of the crushing roller 503 penetrates the baffle and is rotatably connected with the inner wall of the box body 501, so that the material cannot leak from both sides of the crushing roller 503 during crushing and cannot be effectively crushed. The top of the box body 501 is provided with a feeding port, the feeding port is located above the meshing position of the two crushing rollers 503, and the size of the feeding port is smaller than the length and width of the two crushing rollers 503, so that the material can enter from the feeding port and fall between the two crushing rollers 503, facilitating crushing.

[0040] By putting the material from the feeding port into the inside of the box body 501, the second motor 502 drives the crushing roller 503 connected thereto to rotate, and through the meshing of the gear 504, the other crushing roller 503 can be driven to rotate, so that the input material is crushed, and the crushed material falls into the inside of the material control assembly 6 through the discharge pipe 505.

The other crushing roller 503 is driven to rotate through the engagement of the gear 504, thereby crushing the material put in. The crushed material falls into the inside of the discharge bin 601 through the discharge pipe 505. When the discharge opening of the material control tooth disc 603 is misaligned with the discharge opening, the discharge opening is closed to prevent the material from being discharged into the inside of the shell 1. When it is necessary to control the discharge, the third motor 605 drives the material control tooth disc 603 to rotate. Since the material control tooth disc 603 is limited by the limiting piece 603, the material control tooth disc 603 cannot be separated. Since the material control tooth disc 603 is engaged with the transmission disc 606, the material control tooth disc 603 is driven to rotate until the discharge opening of the material control tooth disc 603 corresponds to the discharge opening. Then the material is discharged into the inside of the shell 1 through the discharge opening. When the material is discharged, the third motor 605 is reversed to misalign the discharge opening of the material control tooth disc 603 with the discharge opening again to close the discharge opening, thereby realizing the quantitative discharge.
