Description

Technical Field

[0001] The invention relates to the technical field of rice polishers, in particular to a rice polisher with uniform feeding. Background Art

[0002] In the modern rice processing industry, rice polishing is one of the key processes to improve the quality and glossiness of rice. Traditional rice polishing machines usually adopt a direct feeding method, that is, a large amount of rice is put into the polishing machine for processing at one time. However, this feeding method has obvious problems: on the one hand, too much one-time feeding can easily lead to uneven distribution of rice inside the polishing machine, making some rice incompletely polished, affecting the processing effect of the final product; on the other hand, the broken eyebrows and powder generated during the polishing process are easy to adhere to the surface of the rice, increasing the complexity and cost of subsequent chip removal processing.

[0003] In order to solve the above problems, some improved rice polishers are currently on the market, which try to improve the polishing effect and processing efficiency by optimizing the feeding method and adding a chip removal device. However, these improved polishers still have certain limitations in practical applications. For example, although some polishers adopt a batch feeding method, the control of the feed amount is not precise enough, and the problem of uneven polishing is still prone to occur. Although other polishers are equipped with a chip removal device, the chip removal effect is limited, and additional chip removal processing is often required after polishing, which increases production costs and processing time. Therefore, in response to the above technical problems, a rice polisher with uniform feeding is proposed herein. Summary of the invention

[0004] The purpose of the present invention is to provide a rice polishing machine with uniform feeding, which accurately controls the rice feeding amount through a rotating plate driven by a first motor and a spring mechanism to ensure uniformity during the polishing process. At the same time, an electric push rod vibrating plate is used to further promote uniform distribution of rice and improve the polishing effect. In addition, a fan chip removal system is integrated to effectively clean the debris on the surface of the rice before discharging, thereby simplifying the subsequent processing flow.

[0015] 2. The rice polishing machine with uniform feeding can transport the polished rice to the inside of the storage box through the discharge pipe through the valve after the rice is polished by the polishing machine body. At this time, the second motor can be operated to rotate the spiral push rod, so that the rice in the discharge box is gradually pushed into the dust removal box through the connecting groove by the spiral push rod, and then falls into the collecting box at the bottom, so as to achieve the purpose of rapid discharge; and before discharging, the fan inside the fixed cylinder can be operated to blow air to the dust removal box and the opening outside the dust removal box through the air inlet of the fixed cylinder. Therefore, when the rice falls from the connecting groove, the fan can be cooperated to blow air to the surface of the rice, and the debris or powder contaminated on the outer surface of the rice can be cleaned, thereby ensuring the cleanliness of the rice surface, avoiding subsequent complicated dust removal processing, and being more convenient.
