Multi-tangential-flow drum corn threshing and cleaning device

Abstract

The invention relates to a multi-tangential-flow drum corn threshing and cleaning device, and belongs to the field of agricultural machinery. The device comprises a cutting unit, a threshing unit, a cleaning unit and a collecting unit; the cutting unit comprises an auger (1); the threshing unit comprises a pressure feeding device (2), a thumb shifter type feeding device (12), a primary threshing device (9), a main threshing device (4) and a re-threshing device (5) which are successively arranged from front to back; the pressure feeding device (2) is arranged at the rear of the auger (1); and the cleaning unit comprises a shaking sieve (11), a vibrating sieve (6) and a cleaning fan (10). Corns can be peeled, threshed, cleaned, conveyed and collected mechanically in a whole process, the working efficiency is greatly improved, the labor intensity is reduced, meanwhile, the loss ratio, breakage ratio and impurity content are reduced, the corn harvesting quality is improved, and market space is wide.

Description

technical field

[0001] The invention relates to a multi-cut flow drum corn threshing and cleaning device, which belongs to the field of agricultural machinery. Background technique

[0002] Maize is one of the most widely planted grains in the world and one of the three major food crops in China. It occupies an important position in my country's grain industry. In recent years, my country's corn production has been increasing year by year. By 2015, the total national corn production reached 225 million tons, accounting for 36% of the total annual grain production.

[0003] The development speed of machine-harvested corn at this stage cannot match the growth rate of corn sown area at all. Compared with rice and wheat, the level of mechanized harvesting of corn is still very low, and ear picking is the main method, with many operations and high costs, which is the "bottleneck" that restricts the mechanization of the whole process of corn production. The traditional manual op...

Embodiment Construction

[0069] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0070] Such as figure 1 As shown, a multi-cut flow drum corn threshing and cleaning device includes a cutting unit, a threshing unit, a cleaning unit and a collecting unit.

[0071] The cutting unit includes an auger 1 .

[0072] The threshing unit includes a pressure feeding device 2 , a finger-type feeding device 12 , an initial removal device 9 , a main removal device 4 and a re-extraction device 5 arranged in sequence from front to back.

[0073] The pressure feeding device 2 is arranged at the rear of the auger 1 .

[0074] Such as figure 2 and image 3 As shown, the pressure-feeding device 2 includes a pressure-feeding roller 13 and a pressure-feeding concave plate 24 arranged under the pressure-feeding roller 13 .

[0075] The outer surface of the pinch roller 13 is uniformly distributed with a plurality of pinch strips 27 parallel to the r...
