Description

Technical Field

[0001] This utility model relates to the field of rice screening technology, and in particular to a rice screening machine. Background Technology

[0002] Screening is a crucial pretreatment step in rice processing. Existing rice screening machines have several shortcomings. Common screening machines are inefficient, unable to quickly and effectively separate impurities, shriveled grains, and whole grains; some machines easily damage rice grains during screening, affecting the quality of subsequent processing; moreover, traditional screening machines are mostly manually or semi-automatically operated, with low levels of automation. Based on these issues, a new rice screening machine was designed. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a rice sieving machine. The sieve separates rice grains from impurities and shriveled grains, and the scraper and fan further enhance the separation effect.

[0004] The technical solution adopted by this utility model to solve its problem is: A rice screening machine includes: a conveying mechanism having a starting end and an ending end for conveying rice, the conveying mechanism having a hollow interior with a receiving space, and a first discharge port and a second discharge port communicating with the receiving space; wherein a screen is provided between the first discharge port and the conveying mechanism to allow impurities to be discharged through the first discharge port.

[0005] By adopting the above solution, impurity screening during the rice conveying process can be achieved. Through the design of the conveying mechanism, screening can be carried out simultaneously while conveying rice, which improves processing efficiency, reduces additional screening steps, and saves time and labor costs.

[0006] Furthermore, the conveying mechanism includes: a hollow housing; a drive shaft assembled inside the housing; and auger blades spirally wound around the outer surface of the drive shaft.

[0007] By adopting the above scheme, the conveying mechanism, with its housing, drive shaft, and auger blades, can stably and efficiently transport rice. The spiral winding design of the auger blades propels the rice within the housing, ensuring uniform transport and improving the stability and continuity of the conveying process.

[0008] Furthermore, it also includes a support structure for reserving space between the shell and the ground.

[0009] By adopting the above solution, the support structure reserves space between the shell and the ground, which facilitates the installation of the discharge pipe below, and also helps the equipment to ventilate and dissipate heat. At the same time, it avoids the equipment from being directly in contact with the ground and being affected by environmental factors such as moisture, thus extending the service life of the equipment.

[0010] Furthermore, the support structure includes: a fixed frame, wherein the housing is at least partially embedded in the fixed frame; a support frame, wherein the support frame surrounds the fixed frame in the center; and a caster wheel device, wherein the caster wheel device is disposed below the support frame.

[0011] By adopting the above solution, the fixed frame can stably support the shell, the support frame enhances the stability of the overall structure, and the caster wheel device facilitates the movement of the equipment, enabling the equipment to flexibly adjust its position to adapt to different work site requirements.

[0012] Furthermore, the conveying mechanism also includes a scraper arranged circumferentially along the drive shaft, the position of which is consistent with the position of the screen.

[0013] By adopting the above solution, the rice grains on the screen can be scraped during the conveying process to prevent screen blockage, ensure continuous and efficient screening, and improve screening quality; moreover, by lifting the rice grains, it is easier to separate impurities from the rice grains, and facilitates the passage of impurities through the screen.

[0014] Furthermore, a first discharge pipe communicating with the first discharge port is provided below the fixed frame.

[0015] By adopting the above scheme, it is convenient to collect the impurities separated by the sieve.

[0016] Furthermore, a second discharge pipe connected to the second discharge port is provided below the housing.

[0017] By adopting the above scheme, the rice grains after screening can be discharged smoothly, facilitating subsequent processing or storage.

[0018] Furthermore, a fan is also provided on the outer surface of the drive shaft to blow air onto the rice.

[0019] By adopting the above scheme, impurities and shriveled grains in rice can be further separated, improving the accuracy of screening and enhancing the quality of rice. Attached Figure Description
