Double-flexible grinding and rubbing type millet threshing device

Abstract

A double-flexible grinding and rubbing type millet threshing device comprises a machine frame, a rotary threshing assembly, a micro-motion threshing assembly and a driving assembly, the rotary threshing assembly, the micro-motion threshing assembly and the driving assembly are arranged on the machine frame, the rotary threshing assembly comprises a center shaft, a feeding section, a threshing section and a straw discharging section, and the feeding section, the threshing section and the straw discharging section are sequentially arranged in a butt joint manner in the length direction of the center shaft in a left-and-right manner; a threshing element of the threshing section is a rotatable flexible rubber roller, and the rotatable flexible rubber roller can also rotate around a rigid shaftof the rotatable flexible rubber roller; and the micro-motion threshing assembly is composed of a concave plate screen erected on the machine frame and a swing supporting device arranged below the concave plate screen, and the rotatable flexible rubber roller is matched with the concave plate screen in the micro-motion threshing assembly to form a double-flexible-coupling threshing gap. Accordingto the grinding and rubbing type millet threshing device under the double-flexible coupling effect, the crushing rate of millet in the threshing process can be greatly reduced, and the threshing rateand the threshing quality of the millet are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to a millet grinding and threshing device based on the coupling action of a double flexible rotating threshing unit of a roller and a concave plate. Background technique [0002] In the process of agricultural production, the traditional way of harvesting millet is mainly to harvest millet manually, and then grind the millet with stones, which not only has high labor intensity but also very low production efficiency, making ends meet. Today, as the level of agricultural mechanized production continues to improve, such traditional harvesting methods cannot meet the requirements of the society, so the production of millet in our country is far from enough, and it also greatly limits the development of millet and its related industries in China . [0003] The mechanical millet threshing device in the prior art mainly adopts the full-feeding form at present, an...
