[0039] Specifically, a servo motor 27 is fixedly connected to the left side of the L-shaped plate 26. The servo motor 27 is the power source of the structure. Its output end is closely connected to a gear 5 on the front side to ensure the smooth transmission of power. These rolling rollers 16 are important parts of the device. They can evenly roll the material to ensure the consistency of the output and the uniformity of the particle size. The left side of the rolling roller 16 is closely connected to the left side of the hollow box 1 and can rotate freely on the right side inside the hollow box 1.

[0044] Working principle: Usually, the material to be crushed is first opened with the baffle 8 and placed on the crushing roller 16, and then the servo motor 2 7 is started to cooperate with the gear 5 to drive it. When one of the gears 5 rotates, the multiple gears 5 meshing with the outer wall simultaneously drive the crushing roller 16, and then the crushed material will fall on the placement table 12, and the rest will fall on the conical leakage plate 202 through the chute 14, and then the servo motor 3 17 is started to drive the threaded rod 15, and at the same time, the scraper 11 is cooperated to move along the top of the placement table 12 and the slide The outer wall of the rod 13 slides, and then cooperates to scrape the material on the placement table 12 to fall onto the chute 14, thereby avoiding the accumulation of materials in the inner cavity during the crushing process, and at the same time improving the utilization rate of the equipment. Subsequently, when the material is stored on the conical leakage plate 202, through the rotation of the servo motor 206, the rotating rod 203 and the rotating roller 204 are rotated inside the discharge port 207, thereby avoiding the accumulation of materials inside the discharge port 207, affecting the material discharge efficiency, and at the same time improving the practicability of the crushing equipment.
