Abstract

The invention provides a small-scale threshing and separating device suitable for rice and oilseed rape in hilly and mountainous areas. The small-scale threshing and separating device suitable for therice and the oilseed rape in the hilly and mountainous areas comprises an open roller, a top cover located above the open roller, and a grid-type concave screen located below the open roller; and theopen roller comprises a roller shaft, a feeding head, a plurality of toothed bars and a plurality of wheels, the feeding head and the wheels are sequentially installed on the roller shaft in a crop feeding direction from front to rear, a plurality of rounds of adjusting holes are formed in the wheels, the toothed bars are installed on the wheels through the adjusting holes, the toothed bars are evenly distributed in a peripheral direction with an axis of the roller shaft as a center, and a plurality of rasp bar board tooth groups and spike tooth groups are sequentially arranged on the toothedbars in the crop feeding direction. The small-scale threshing and separating device suitable for the rice and the oilseed rape in the hilly and mountainous areas can be suitable for threshing and separating of the oilseed rape and the rice in the hilly and mountainous areas, and has the advantages of being low in threshing loss ratio and high in cleaning ratio.

Description

technical field

[0001] The invention relates to the technical field of combine harvesters, in particular to a small threshing and separating device suitable for rice oil in hilly and mountainous areas. Background technique

[0002] The production mode of rice oil and rice oil rotation is mostly used in hilly and mountainous areas. The existing problems of the combine harvester are as follows: 1. Since the rice is mostly early rice, the rice quality is loose, the grain connection force is small, the pressure resistance is poor, and the threshing damage is large during harvesting. Second, due to the large plant type and many branches of rapeseed, the maturity consistency is poor, the loss rate is high during harvest, and cleaning is difficult.

[0003] The harvest of rice and rapeseed has a strong seasonality, and the labor intensity of manual operation is high, the efficiency is low, the harvest loss is large, and it takes up a lot of farming time. The mechanized harvesting ...
