[0031] Working principle: In the current prior art, crushing equipment is generally divided into two types. One is a rotary knife crusher, which relies on a high-efficiency rotating crushing knife to crush the polygonatum. Its crushing efficiency is high, but the precision of the crushed particles is low. The other is a grinding type, which is built with an upper and lower grinding seat, with grinding teeth on the inner wall of the grinding seat. The upper grinding seat 15 is provided with a conical chamber, and the lower grinding seat 16 can be inserted into it. This type of grinder has high grinding precision, but its grinding effect is low. When the present application is in use, the polygonatum is put in from the top of the silo 11, and then falls into the crushing chamber, and is initially crushed by the high-speed rotating crushing knife to crush it into larger polygonatum particles, and then falls to the bottom. The upper grinding seat 15 and the lower grinding seat 16 are used for grinding and crushing, so as to improve the overall grinding accuracy, improve the uniformity of the crushed particles, and improve the fineness of the particles. At the same time, the large pieces of polygonatum sibiricum are broken into smaller particles by the preliminary crushing in advance, so that the grinding and crushing can be carried out conveniently. The polygonatum sibiricum particles crushed by the crushing knife can be screened by the arranged screening mesh plate 21, and the larger ones are left in the upper layer and scraped by the stirring scraper 22, and then rolled in the crushing chamber for contact with the crushing knife again. The staff can rotate the screw 32 according to the particle size of the polygonatum sibiricum powder to be ground, and the rotation of the screw 32 will drive the screw sleeve 31 to move up and down, so as to drive the upper The grinding seat 15 moves to adjust the distance between the upper grinding seat 15 and the lower grinding seat 16, so as to control the coarseness of the grinding, which can be convenient for the staff to use. Relying on the set guide rod 42 and the sliding sleeve 41, the sliding sleeve 41 can slide on the guide rod 42. Relying on this setting, the fixing effect of the upper grinding seat 15 can be improved, thereby reducing its shaking, and further reducing the collision between the upper grinding seat 15 and the lower grinding seat 16 due to shaking when grinding finer Huangjing powder. According to the size of the equipment, the bracket can be installed inside the grinding cylinder 13 as needed to fix the rotating shaft to ensure the concentricity of the rotating shaft during rotation. The material discharge seat 51 is set in a conical shape, and the middle part is upward. The protrusion 54 can be used to collect the polygonatum powder, and then the polygonatum powder is discharged from the discharge port. The discharge motor 52 drives the scraper 53 to rotate, so as to reduce the polygonatum powder remaining in the discharge seat 51. Due to the rapid rotation of the transmission shaft 14, the grinding between the upper grinding seat 15 and the lower grinding seat 16 will heat up, and when the temperature is high, it will destroy some components in the polygonatum. The water inlet pipe is connected to the external cooling water pump, and the cooling water pump is used to pump coolant into the cooling water tank 6. The coolant then flows in the cooling tank and is discharged from the water outlet pipe at the other end, so as to cool the upper grinding seat 15, thereby reducing the temperature during long-term polygonatum grinding, and then reducing the damage to some components.
