A millet half-feed threshing device

Abstract

The invention discloses a head-feed threshing device for foxtail millet. The device comprises a feeding plate, a millet pressing mechanism, a threshing mechanism, a screening mechanism and a discharging hopper, the millet pressing mechanism and the threshing mechanism are arranged side by side, and the threshing mechanism, the screening mechanism and the discharging hopper are arranged in sequencefrom top to bottom; the millet pressing mechanism comprises a millet pressing chain plate on the upper portion and a conveying belt on the lower portion, a feeding end of the conveying belt is connected with the feeding plate, and the rotation direction of the conveying belt is opposite to that of the millet pressing chain plate to convey the foxtail millet; multiple L-shaped millet pressing plates are arranged on a main chain plate body of the millet pressing chain plate at intervals, one plate surface of each millet pressing plate is vertically arranged on the main chain plate body, and theother plate surface of each millet pressing plate extends in the opposite direction of motion of the millet pressing chain plate; a millet pressing space is defined by the adjacent millet pressing plates, the conveying belt on the lower portion and the main chain plate body, foxtail millet stems are pressed, and meanwhile the adjacent millet pressing plates clamp the foxtail millet stems. The head-feed threshing device for the foxtail millet is simple in mechanism, small in size, low in mass, complete in threshing, low in smashing or shelling rate and higher in separation cleaning rate.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a millet half-feeding threshing device. [0002] technical background [0003] Rice is the largest grain crop in my country. Less than 30% of the rice planting area has produced about 40% of the world's total grain. In recent years, the rice planting area has been steadily increasing, and the heavy rice harvesting and threshing work Harvesters and threshers play an important role in it. At present, my country's millet harvest mainly adopts two methods. One is that most areas are still manually harvested, and threshers are used for on-field threshing; the other is that a small number of areas are harvested by windrowers, and then the ears are picked and threshed after drying or directly threshed by threshers. In recent years, there are also enterprises or farmers who use grain combine harvesters such as wheat or rice, and carry out millet harvesting after slight m...

Problems solved by technology

[0004] In view of the above problems, the object of the present invention is to propose a half-feed millet threshing device, which eliminates the defect of high energy consumption of the full-feed type, and at the same time makes the whole mechanism obviously simple, with reduced volume and quality, clean threshing, broken or Less shelling, higher separation and cleaning rate
