Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding device used for the production of agricultural products. Background Art

[0002] Agricultural product grinding is a frequently used method in agricultural product production and processing. In the existing agricultural product grinding device, during the agricultural product grinding process, as the volume of the agricultural product is smaller, the grinding pressure of the upper grinding disc on the agricultural product is reduced, so that part of the agricultural product cannot be effectively ground, thereby reducing the grinding quality.

[0003] At present, a Chinese patent announcement with announcement number CN212549783U discloses an agricultural product grinding device, including a processing box, a motor is fixedly installed in the middle of the top surface of the inner cavity of the processing box, the bottom end of the output shaft of the motor is fixedly connected to the inner rotating shaft, and the outer part of the inner rotating shaft is movably connected to the outer rotating shaft. The agricultural product grinding device drives the inner rotating shaft to rotate through the output shaft of the motor, and the inner rotating shaft drives the outer rotating shaft to rotate. At the same time, under the action of the spring inside the outer rotating shaft, the outer rotating shaft rotates and moves downward, and at the same time, pressure is applied downward, so that the agricultural products are fully and effectively ground. When the agricultural products that have achieved the grinding effect enter the receiving box through the discharge hole, the upper grinding disc moves downward under the action of gravity and spring tension, so that the agricultural products still inside the baffle are fully and effectively ground. The agricultural product grinding device achieves the effect of uniformly grinding the agricultural products.

[0004] In actual production, it is found that when the spring is used to apply downward pressure to the grinding disc, the force applied by the grinding disc is unstable due to the elastic properties of the spring itself, which can easily lead to insufficient grinding and material jamming. Therefore, we propose a grinding device for agricultural product production to solve the above problems. Utility Model Content
