Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a polishing machine for rice processing. Background Art

[0002] Rice is one of the main grains processed through cleaning, husking, milling and finishing. As the basis of daily diet for people around the world, it not only provides essential carbohydrates for the human body, but also contains a variety of nutrients such as protein, vitamins, minerals, etc. Rice is polished during processing. This process is mainly to improve the appearance quality, storage and taste of rice. The purpose of polishing rice is to improve its appearance and edible quality through physical methods, and it is also convenient for storage and transportation.

[0003] After searching, the Chinese patent document announcement number is: CN219631385U, a polishing machine for rice processing, which includes an externally arranged shell, a sewage outlet arranged in the middle of the bottom end of the shell, a vibrating screen obliquely installed at the bottom of the inner side of the shell, a polishing roller symmetrically installed at the top of the inner side of the shell, a driving motor installed outside one end of the polishing roller and a feed hopper arranged in the middle of the top end of the shell, and also includes an inclined plate, an auxiliary unloading mechanism and a dust removal port, the inclined plate is fixed to the bottom of the inner side of the feed hopper, the auxiliary unloading mechanism is installed on the shell on one side of the feed hopper, and the dust removal port is opened at the bottom of one side of the shell; the auxiliary unloading mechanism includes a box body, a spring and a rubber head, the box body is fixed on the top of the shell, and a disc is installed in the middle of the inner side of the box body. The utility model has a novel structure and an ingenious conception, so that the rice is unloaded in a straight line, and the rice can contact the polishing roller more evenly to ensure the polishing uniformity of the polishing roller. At the same time, the rubber head at one end of the square rod knocks the feed hopper to ensure the unloading efficiency of the feed hopper.

[0004] Although the above patent mentioned in the specification that "when the utility model is used, the driving motor drives the polishing roller to rotate, and the rice to be polished is added from the feed hopper, and then enters the polishing roller for polishing after passing through the inclined plate. The polished rice falls onto the vibrating screen. When the rice falls, the floating dust is adsorbed by the dust removal fan connected to the dust removal port, and the granular foreign matter is screened to the bottom by the vibrating screen. The rice flows to the right side of the vibrating screen and is collected. The screened granular foreign matter is discharged through the sewage outlet. The inclined plate is set to make the rice discharge in a straight line. In this way, the rice can contact the polishing roller more evenly, ensuring the polishing uniformity of the polishing roller. When in use, the motor works, and the motor drives the disc to rotate. When the disc rotates, the arc-shaped rack on the disc drives the rack to move to the right, and the rack drives the square rod to move to the right , the square rod moves and drives the limit block to compress the spring on the right side. When the arc-shaped rack separates from the rack, the spring pushes the limit block to reset, and the limit block resets and pushes the square rod. The rubber head at one end of the square rod knocks the feed hopper to ensure the feeding efficiency of the feed hopper. When the disc rotates, it drives the square rod to move reciprocatingly. The utility model has a novel structure and ingenious conception, so that the rice is discharged in a straight line. The rice can contact the polishing roller more evenly to ensure the polishing uniformity of the polishing roller. At the same time, the rubber head at one end of the square rod knocks the feed hopper to ensure the feeding efficiency of the feed hopper. However, when the rice is in contact with the polishing roller for polishing, the rice will be squeezed and damaged, and the contact area between the rice and the polishing roller is insufficient, resulting in low polishing efficiency. Therefore, in view of the above shortcomings, a polishing machine for rice processing is proposed. Utility Model Content
