Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice paddy and brown rice separator. Background Art

[0002] A paddy and brown rice separator is a key device used for separating paddy from brown rice during the rice processing process, and has an efficient and stable separation function.

[0003] The utility model patent with the authorized announcement number of CN220345914U discloses a rice processing paddy and brown rice separator, which includes a first box body. A first sieve plate is arranged inside the first box body. The first sieve plate and the second sieve plate are connected by a rocker arm and shake. Symmetrically arranged rubber rollers are arranged inside the second box body. One end of each rubber roller is connected with a fourth connecting shaft. A first gear is arranged on one of the fourth connecting shafts, and a second gear is arranged on the other fourth connecting shaft. The first gear and the second gear are both meshed with a third gear. A third sieve plate is arranged at the lower end of the rubber rollers. A third driving motor is arranged at the upper end of the second motor bracket. Eccentric blocks are symmetrically arranged on the output shaft of the third driving motor. The operation of the utility model is convenient and the structure is simple. The paddy and brown rice fall into the first box body from the feeding chute. When the first driving motor outputs, it drives the first sieve plate and the second sieve plate to vibrate and screen, removing impurities. After the impurities are removed, the paddy and brown rice fall into the rubber rollers. The paddy and brown rice are squeezed and rubbed to achieve the purpose of shelling. The third sieve plate vibrates and screens to separate and collect the rice husks and rice.

[0004] When separating rice, the above patent uses a vibration screening method to screen the paddy and brown rice of rice. Among them, an open-ended screening and discharging method is adopted on the side of the first box body. During the vibration process, the rice that has not been filtered by the sieve will directly splash out from the side of the open-ended opening, resulting in incomplete screening and separation. Furthermore, there will be a phenomenon of admixture in the screened paddy and brown rice of rice. For this reason, we propose a rice paddy and brown rice separator to solve the above problems.
