Embodiment Construction

[0028] as attached figure 1 As shown in the figure, the self-propelled longitudinal double axial flow millet combine harvester used in the wind screen cleaning device researched and designed by this patent includes a stepped shaking plate (I), a stepped punching type upper cleaning screen (IV), and a braided lower screen. Cleaning screen (Ⅴ), braided tail screen (Ⅵ), cross-flow fan (Ⅱ), crank swing arm drive mechanism (Ⅲ) and other main functional components, the overall air screen cleaning device is installed and arranged in the form of longitudinal correspondence. In the inner cavity of the machine body below the longitudinal double axial flow threshing separation device provided in the main machine, the front end is hinged to the shaking plate support seat provided on the inner side of the front part of the left and right side walls of the main machine respectively through the left and right shaking plate swing arms (17). The rear end is hinged to the upper screen hanger pr...

Abstract

The invention discloses an air-screen cleaning device for a self-propelled longitudinal dual-axial millet combine harvester. The air-screen cleaning device consists of main operation functional parts including a step type shaking plate, a step punching type upper cleaning screen, a woven lower cleaning screen, a woven tail screen, a cross-flow fan, and a crank rocking arm drive mechanism. The air-screen cleaning device has grain cleaning operation functions such as a constant shaking, loosening, dispersing and uniform material conveying function, a rough fine two stage large area relative reciprocating shaking cleaning function, a fine crushed leaf and stem airflow blowing discharging function, a bilateral supporting balanced synchronous drive operation function, and a spikelet grain-contained residue collection and threshing function, can solve the technical problems that in a grain cleaning operation technical link, the conventional millet harvesters are low in cleaning trafficability, and are small in effect cleaning operation area; crushed straw and leaves are kinked and gathered to block a screen surface, cleaning material feeding is uneven, the trash content of grains is high, and carrying loss is huge. The air-screen cleaning device can meet the grain cleaning technical condition demand of mechanical harvesting of millet crops in different conditions.

Description

technical field [0001] This patent relates to a special component for agricultural machinery, in particular to a self-propelled longitudinal dual-axial flow millet combine harvester that is closely coordinated with a longitudinal dual-axial flow threshing and separation device and is used for mechanically harvesting millet crops for grain cleaning operations. Air sieve cleaning device. Background technique [0002] Millet crop originated in my country and has been cultivated on a large scale for more than 8,000 years. It was called millet or millet in ancient times. It has been an important food variety in my country since ancient times. , strong adaptability and so on. my country's northern provinces such as Hebei, Shandong, Shanxi, Shaanxi, Jilin, Liaoning, and Inner Mongolia have always been the main producing areas of millet crops. At present, the total annual output of millet crops has reached more than 2.8 million tons, accounting for about 80% of the world's total out...
