Multi-stage rice impurity removing device

Abstract

The invention discloses a multistage rice impurity removing device comprising a feeding bin, a first impurity removing bin and a second impurity removing bin which are sequentially arranged from top to bottom, a first partition plate is arranged between the feeding bin and the first impurity removing bin, and a second partition plate is arranged between the first impurity removing bin and the second impurity removing bin. The feeding bin is provided with a feeding port, a propelling motor is further arranged at the upper end of the feeding bin, and a screw rod of the propelling motor extends into the feeding bin and is correspondingly provided with a screw feeding blade with the downward feeding direction. According to the device, an impurity removing device for removing rice hulls throughwind power and an impurity removing device for removing unqualified rice through a color sorting technology are arranged in a combined manner, and achieve multi-stage impurity removing through cooperation of the first impurity removing bin and the second impurity removing bin which are arranged up and down.

Description

technical field [0001] The invention relates to the field of rice processing technology and equipment, in particular to a multi-stage rice impurity removal device. Background technique [0002] There are many kinds of rice removal work in the prior art. When the rice is processed in the early stage, it is necessary to remove some larger sand and gravel debris in the rice. The equipment section of this part uses a centrifugal principle machine accordingly. , the efficiency is high; after this part of the sundries are removed, the husk of the rice is also separated, usually by rolling and separating the husk of the rice, and when the husk of the rice is separated, it is necessary to separate the husk from the rice. Separation, this part of the equipment usually uses wind equipment to blow away the rice shell to achieve the effect of separation and impurity removal; and after the rice shell is separated, some unqualified, deteriorated, and wrong color rice inside the rice is al...

Problems solved by technology

[0002] There are many kinds of rice removal work in the prior art. During the pre-processing of rice, it is necessary to remove some larger sand and gravel impurities in the rice. The equipment section of this part adopts the machine of centrifugal principle to remove impurities. , the efficiency is high; after this part of debris is removed, the husks of the rice have to be separated, usually by rolling and separating equipment to separate the husks of the rice, and when the rice husks are separated, these rice husks need to be separated from the rice Separate, this part of the equipment usually uses wind power equipment to blow away the rice shell to achieve the effect of separating and removing impurities; and after separating the rice shell, it is necessary to separate some unqualified, deteriorated, and wrongly colored rice inside the rice The color sorting device is usually selected to carry out this part of the impurity removal work; on the one hand, the existing equipment cannot combine rice hulling and color sorting and impurity removal, and the two are set separately, which will increase the process and waste accordingly In addition, the effect of the existing rice hulling and impurity removal is not ideal, and the impurities cannot be removed; and in the color sorting device, usually after the color is identified, the unqualified rice is sprayed out through the air jet device. The disadvantage is that if the air injection time and recognition rate are not well controlled, the qualified rice above will be sprayed out at the same time as the air injection, which is very troublesome
