A lightweight harvester

Abstract

The invention provides a light and simple harvesting machine which comprises a crop pulling wheel, an inclined conveyor, a threshing cylinder, a screening and conveying auger, a grain tank, a grain conveying auger, a drum sieve, a control console and a header. The crop pullling wheel is arranged on the header and used for pulling up crops to be cut by cutting knives in the header. One end of the inclined conveyor is connected with a discharging opening of the header, and the other end of the inclined conveyor is connected with a feeding opening of the threshing cylinder. A discharging opening of the threshing cylinder is connected with one end of the screening and conveying auger, and the other end of the screening and conveying auger is connected with a feeding opening of the drum sieve. The grain conveying auger is located on the lower inclined portion of the drum sieve. The grain conveying auger is in an L shape, and the output end of the grain conveying auger is connected to the grain tank used for storing crops. According to the harvesting machine, screening is conducted through the drum sieve which is rotating movement equipment without a center axis, the mass of the whole machine is lowered, rotating is steady, noise is less, impact is less, and the service life is longer.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to an agricultural harvester, in particular to a light and simple harvester. Background technique [0002] At present, the penetration rate of grain harvesting machinery in the plain areas of my country is relatively high at this stage, and the grain planting area in hilly mountainous areas, which accounts for about 43% of the country's land area, is relatively extensive. Due to the small and irregular fields and the large height difference between adjacent fields, the seasonal Influenced by factors such as large differences in nature and operating environment, it is impossible to use mature large-scale combine harvesters in plain areas, which makes the harvest rate of agricultural mechanization in such areas low and restricts the transfer of rural surplus labor in this area. Compared with the traditional reciprocating vibrating screen, material cylindrical screen has obvious ad...

Problems solved by technology

Whether this mechanism can be applied to grain combine harvesters has aroused the interest of some scientific researchers and agricultural machinery workers in recent years, but the research results reported on this issue are mostly theoretical analysis, which is related to the application of this mechanism on grain combine harvesters There is a lack of in-depth and systematic research on the relationship between the quality of clear grain and the movement parameters and structural parameters of the mechanism
