Abstract

The invention particularly relates to a centrifugal threshing device for coarse cereal crops, and solves problems that an existing threshing device is poor in separation effect, high in grain damage rate and easy to block and influences threshing efficiency. The centrifugal threshing device includes a box-type rack, a top cover is arranged at an upper end of the box-type rack, a feeding inlet is arranged at a lower part of a left side wall of the box-type rack, a spiral feeding device and a threshing cylinder are arranged in the box-type rack, a transmission shaft is arranged in the box-type rack, a hollow shaft sleeve is sleeved on the transmission shaft, and a spiral pushing device is arranged on the hollow shaft sleeve; the spiral feeding device comprises a conical feeding cylinder andspiral blades; the spiral pushing device comprises a connecting plate, a strip-shaped supporting plate is fixed on the connecting plate, a semi-arc pushing disc is arranged on the strip-shaped supporting plate, the semi-arc pushing disc is hinged with the strip-shaped supporting plate and an adjusting pull rod, and a scraping plate is arranged on the strip-shaped supporting plate. The centrifugalthreshing device avoids damage to seeds in previous processes of impact, kneading and combing, reduces damage rate, retains integrity of straw, and reduces impurity content.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural threshing device, in particular to a centrifugal threshing device for miscellaneous grains. Background technique [0002] Coarse grains are rich in nutrition and have high economic benefits. They are important ration varieties for improving dietary structure and promoting nutrition and health, and are also important economic crops for improving farmers' income in old, young, frontier and poor areas. Millet and buckwheat are the main components of my country's characteristic miscellaneous grains, mainly distributed in Hebei, Shanxi, Inner Mongolia, Yunnan and other regions of China. The level of mechanized harvesting of miscellaneous grains is low, and most of them stay in the stage of manual harvesting. The labor intensity is high, the efficiency is low, and the loss is high, which no longer meets the needs of the development of miscellaneous grains industry...
