As the main bevel gear 707 rotates, the slave bevel gear 708 meshing with the main bevel gear 707 is driven to rotate. When the bevel gear 708 drives the first screw rod 802 to rotate on the feed seat 2, the positioning seat 801 slides along the inner wall of the first spring 506, so that the positioning seat 801 contacts the sliding seat 504, so that the distance between the first crushing roller 501 and the second crushing roller 502 changes, thereby further improving the crushing degree of the raw material, facilitating the improvement of the crushing rate of the raw material in the crushing chamber 3, ensuring the feeding rate, and avoiding the accumulation of raw materials in the crushing chamber 3; The second screw rod 902 rotates to make the shielding seat 901 slide on the feeding seat 2 to shield the feeding seat 2, effectively slowing down the feeding rate and further avoiding excessive material in the crushing chamber 3, resulting in poor crushing effect.
