Rice washer

Abstract

Provided is a rice washer, comprising a rice washing case for washing rice, a meter which conducts counting on rice and feeds rice into the rice washing case, an upper hopper which can store rice and supply rice to the meter, a negative pressure unit which enables the internal part of the upper hopper to have negative pressure, a rice storing warehouse which is disposed below the rice washing case and stores rice, and a rice conveying unit which attracts and conveys rice in the rice storing warehouse by means of the negative pressure in the upper hopper. The rice conveying unit is provided with a suction port which is disposed at the lowest part of the side wall of the rice storing warehouse and is used for rice fetching. The suction port is connected to a rice channel for attracting rice and is connected to a rice attracting component communicated with the upper hopper, forming an air channel which is adjacent to the rice channel (17a) of the rice attracting component, and attracts air from outside of the rice storing warehouse to generate negative pressure of the rice channel. With the rice washer, rice at the bottom of the rice storing warehouse can be reliably attracted.

Description

technical field [0001] The invention relates to a rice washing machine which can transport and supply rice (including grains such as wheat) in a rice storehouse to an upper funnel by using the suction of air. Background technique [0002] In this prior art, for example, as disclosed in Patent Document 1, there are: a rice washing box for cleaning rice, a meter for measuring and supplying rice to the rice washing box, and a meter for storing and supplying rice. The upper hopper to the meter, the negative pressure unit that makes the inside of the upper hopper negative pressure, the rice storage bin that is located below the rice washing box and stores rice, and uses the negative pressure inside the upper funnel to release the rice in the storage bin. Suction feeds to the rice delivery unit of the upper funnel. [0003] In addition, the rice conveying unit has: a rice suction member disposed in the rice storage, a rice conveying member that connects the rice suction member to...

Problems solved by technology

[0005] In the above-mentioned prior art, since the lower end suction surface of the rice suction member is located above the bottom surface of the rice storehouse, is inclined relative to the horizontal plane, and opens obliquely downward, sometimes the rice cannot be drawn on the back side of the lower end suction surface of the rice suction member. attract and remain
