Description

Technical Field

[0001] The utility model relates to the technical field of cereal food processing, in particular to a combined device for ultrafine grinding of cereals. Background Art

[0002] After searching, it was found that the publication number is CN214863998U, and the name is a superfine grinding device for grain food processing. The application points out that at present, most grain food grinding devices have a grinding dead angle when grinding grains, resulting in incomplete grinding and poor grinding effect. By setting a connecting rod, the connecting rod can push the slider to slide back and forth inside the through groove under the cooperation of the motor, threaded rod, threaded cylinder and connecting rod. By setting a gear, under the action of the rack, the gear drives the connecting shaft and the rolling cylinder to rotate, so that the rolling cylinder can move left and right while grinding the grains. By setting a scraper, when the rolling cylinder is close to the scraper, the scraper is squeezed by the L-shaped plate, so that the scraper and the rolling cylinder are in contact with each other. The inner wall of the second support frame engages to enable the rolling cylinder to roll the grains at the original position of the scraper. By setting a spring, the scraper can push the grains in the corner to reset after the rolling cylinder moves away from the scraper, ensuring that the grains can be rolled and crushed, and the crushing effect is better. However, this application adopts a complex reciprocating movement structure and a scraper operation structure, which has a complex structure and high production cost, and the linear reciprocating rolling and crushing action is not efficient, which affects the ultrafine crushing speed and efficiency. Further improvements can be made. In addition, when discharging, this application needs to separate the protective cover on the magnet from the protective cover on the top plate, and then rotate the sealing plug, which is very troublesome and affects the use efficiency. Further improvements can be made.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
