Rice hulling device with screening function

Abstract

The invention discloses a rice hulling device with a screening function. The device comprises a hulling box; a feeding pipe is fixedly mounted at the top of the hulling box; a limiting plate is arranged on the side wall of the hulling box, and is in vertical threaded connection with a lead screw; a support plate is fixedly mounted on the right side wall of the hulling box; a driving motor is fixedly mounted on the support plate; a driven shaft parallel to a driving shaft is rotationally arranged in the hulling box; and a second driving belt wheel is fixedly mounted on the driving shaft. The device is convenient to hull and screen rice, low in workload and high in efficiency, rotationally hulls the rice through rotation of an adjusting pressure roller, a first hulling rotating roller and a second hulling rotating roller, greatly improves the rice hulling efficiency, and realizes quick hulling of the rice; and the up-down position of the adjusting pressure roller can be adjusted through a rotating lead screw, so that the position adjustment of the adjusting pressure roller and the first hulling rotating roller and the second hulling rotating roller is realized, the hulling extrusion acting force is increased, and the rice hulling is more thorough.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rice hulling device with a screening function. Background technique [0002] Rice is native to China, and rice was planted in the Yangtze River Basin of China 7,000 years ago. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Chinese scientist Yuan Longping has made great contributions to the research of hybrid rice and is known as the "father of hybrid rice". The fruit of rice is rice paddy, which is called brown rice after the chaff is removed, and rice can be obtained by grinding the rice bran layer off the brown rice. Nearly half of the world's population feeds on rice. There are various ways to eat rice, such as rice, rice porridge, rice cakes, rice cakes, rice wine and so on. In addition to being edible, rice can also be used as industrial r...

Problems solved by technology

[0003] In the further processing of rice, it is necessary to peel off the rice shell of rice to obtain rice that can be cooked and eaten. The existing rice shelling device has a fixed structure and poor adjustability, and the shelling effect on rice is not good. The rice cannot be shelled well, and the rice obtained after shelling needs to be sieved according to its particle size, and the workload is relatively large
