[0002] A rice crushing device for agricultural product processing is a device used to process rice into rice or other by-products. It is usually used in rice processing plants or farmers to husk, grind and screen rice to produce products such as rice and rice bran of different qualities. Rice refers to the seeds without removing the rice husk. Botanically, it belongs to the common rice subspecies in the common cultivated rice subgenus of the genus Oryza in the family Gramineae. Humans have identified 22 types of rice, but the only one used for bulk trade is common rice. In the process of rice processing, a crushing device is needed to process the rice into a by-product of rice.

[0003] After searching, a Chinese patent document with announcement number CN216173128U provides a rice crushing device for agricultural product processing, including a crushing cylinder and a conical bucket fixed at the lower end of the crushing cylinder, a crushing piece for crushing rice is installed at the upper position inside the crushing cylinder, two connecting seats are symmetrically fixedly connected to the outer surface of the lower end of the crushing cylinder, a cloth cylinder for preventing rice dust from floating is installed at the lower end of the conical bucket, a support ring is fixedly connected to the lower end of the cloth cylinder, a connecting rod is fixedly connected to the outer surface of the support ring, and the end of the connecting rod away from the support ring is fixedly connected to the movable end of an electric push rod, the cylinder end of the electric push rod is fixed to the lower surface of the connecting seat, and a collecting piece for collecting rice dust floating in the crushing cylinder is connected to the outer surface of the conical bucket. Compared with the prior art, the utility model has the following beneficial effects: it can prevent the dust of agricultural products such as rice from floating around at will during the transfer process, which is conducive to maintaining the cleanliness of the working environment.

[0004] The beneficial effects of the above patent specification mentions that "before crushing rice and other agricultural products, the electric push rod is controlled to extend, and then the electric push rod drives the lower end of the cloth drum to move downward through the connecting rod, so that the cloth drum unfolds and extends to the collecting container on the lower side of the conical bucket, and then the crushed rice and other agricultural products fall into the collecting container through the cloth drum, thereby preventing the dust of rice and other agricultural products from floating around during the transfer process and reducing the waste of resources."

At this time, the connecting column 4 will drive the cam 5 to rotate. At this time, the cam 5 will hit the bottom of the connecting column 7 while rotating. At this time, the connecting column 7 will shake up and down. At this time, the spring 8 will be compressed. The connecting column 7 will push the sieve plate 6 to shake during the movement. After the rice falls to the top of the sieve plate 6, the rice and the rice husk are separated by shaking, and the rice husk falls to the top of the conveyor belt 13. As the conveyor belt 13 moves, it is sent to the discharge port and discharged from the inside of the processing box 1. After that, the rice enters the inside of the crushing box 17, and is crushed with the rotation of the crushing roller 19 and the crushing roller 21. Then, it falls to the top of the box door through the guide plate. After the processing is completed, the box door is opened by the handle to collect the rice.
