The invention relates to the field of agricultural product processing equipment, in particular to a rice grinding device.

Background

The rice is a finished product prepared by the working procedures of rice cleaning, rice hulling, rice milling, finished product finishing and the like. The rice contains 64 percent of nutrient substances in the rice and more than 90 percent of nutrient elements required by human bodies, is a main food for people in most areas in China, and particularly is an indispensable staple food for three meals a day in southern areas in China. At present, rice can be eaten after simple cooking such as steaming and boiling, and can be subjected to fine processing to produce other products with different eating methods, and devices such as grinding and the like are needed when the rice is processed.

For example, the national invention patent with the patent number of CN110227591A discloses a self-circulation grinding device for rice processing, which comprises a shell, a grinding shaft, a grinding blade, a first transmission belt and a grinding disc, wherein a grinding mechanism is arranged in the shell, a material guide plate is arranged below the grinding mechanism, a rice milling mechanism is arranged below the material guide plate, a sieve plate is arranged below the rice milling mechanism, the grinding disc is arranged at the bottom of the shell, and a circulation mechanism is arranged on the outer side wall of the shell; however, the device adopts a manual feeding mode, which consumes manpower, cannot judge the degree of grinding the rice in the grinding device, cannot determine the feeding time and whether the grinding mechanism is damaged, and has a poor grinding effect of the grinding blade on the rice.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: overcome prior art's not enough, provide a safe effectual rice grinder, device simple structure, easy to operate can detect whether normal work of degree and the reducing mechanism that the rice ground in the grinder, can be reinforced according to the crushing degree automation of rice to improve the grinding effect of rice.

The technical scheme adopted by the invention for solving the technical problems is as follows: rice grinder, including grinding case, feed box and receipts workbin, be equipped with first motor in grinding case's the top cap, control panel is equipped with to the top cap surface, and the rotary rod is connected down to first motor, is equipped with on the rotary rod and smashes sword and speed sensor, and first motor and speed sensor link to each other with control panel, and the feed box passes through the filling tube and is connected to the top cap, is provided with electronic baffle on the filling tube, and electronic baffle passes through the baffle control line and is connected to control panel. The rice is crushed by the crushing knife controlled by the first motor, and the control panel is provided with the rotating speed of the rotating rod; the speed measuring device tests the rotating speed of the rotating rod and judges whether the rotating rod is damaged or not and the quantity of the rice in the grinding box; when the rice is too much, the rotating rod rotating speed is slowed down to a certain numerical value, and the control panel controls the electric baffle to fall down and stop feeding.

Further, 2 are no less than to the quantity of rotary rod, and the quantity of smashing the sword on every rotary rod is no less than 2, smashes the sword and wind rotary rod evenly distributed on the horizontal direction, crisscross distribution each other in the vertical direction.
