Longitudinal axial flow double-drum wheat threshing and separation device for plot breeding

technical field

Background technique

The food problem is one of the most serious concerns of human beings. The development of the breeding industry plays a very important role in increasing food production and ensuring food security. In order to improve the efficiency and quality of crop breeding, it is necessary to develop breeding mechanization and improve the level of mechanized breeding operations.

At present, the harvesting of wheat seeds in community breeding in my country is still dominated by manual harvesting, threshing by ordinary threshers, and cleaning by cleaning machines. The harvesting period is long and the indirect losses are large. Most domestic breeding wheat threshing devices use a single axial-flow nail-toothed drum, which has high power consumption and strong striking ability. The axial-flow drum rotates and moves forward to complete threshing successively, resulting in a high rate of damage to the grains, broken stalks, and uneven threshing mixture, which increases the subsequent cleaning load, easily causes seed loss and mixing, and results in breeding test data. distortion,. The research and production of plot breeding and harvesting machinery in foreign countries is relatively early. At present, the plot breeding wheat harvesting machinery designed and produced by German Haig Company, Austrian Winter Steiger Company, and Danish Hall Company has reached the international advanced level, but foreign countries The area of the breeding test plot is large, the isolation bandwidth is large, the seed harvesting machinery used is bulky, the structure of the threshing and separation device is complicated, and the price is expensive, which is difficult to meet the requirements of the breeding and harvesting test in my country.
