Description

Technical Field

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

[0002] Rice, also known as rice, is a food made from rice grains after processes such as cleaning, husking, milling, and finished product sorting. When rice is processed, it needs to be screened to separate the broken rice and powder in the rice, leaving only qualified rice grains. A screening device is needed for screening.

[0003] At present, a Chinese utility model with the announcement number CN215744707U discloses a novel rice screening machine, including a base, a foot brake roller, a fixed block, a shock absorbing spring, a main body, a screen, a discharge port, a water tank, a waste outlet, a nozzle and a vibration motor.

In the utility model, a nozzle and a water tank are designed, and the water in the water tank is sprayed out in the form of water mist through the nozzle to avoid raising dust and affecting the health of the staff, a foot brake roller is designed to facilitate the movement of the device through the foot brake roller, and a waste outlet is designed to gather the waste through the waste outlet to avoid the waste splashing everywhere and increasing the difficulty of cleaning work.

[0004] To sum up, although the screening machine can achieve the purpose of screening, there are still certain problems when using it. For example, the screen structure and the frame on the screening machine are fixedly installed. When it needs to be replaced and repaired or the mesh size of the screen structure needs to be changed, it is necessary to disassemble the fixings or bolts, which is troublesome and inconvenient to replace and disassemble. At the same time, traditional screening machines are generally equipped with hoppers, and the hoppers of traditional screening machines cannot achieve the function of evenly spreading the materials. When unloading the materials, the materials will form a certain thickness of accumulation, which leads to the situation that the materials to be screened are not screened out during the screening process, and the screening effect is poor. Utility Model Content

[0005] The utility model aims to provide a rice processing screening machine, which has the advantages of convenient disassembly and replacement and good screening effect.

[0020] The utility model is further configured as follows: the bottom of the frame is connected with a waste discharge cavity, and the other end of the frame is bolted with a material guide plate.

[0021] The above technical solution is adopted to facilitate the unloading of screened waste and good products.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model is provided with a frame body inside the frame, and a guide block is installed on the frame body.
