Sufficiently-threshed whole-feed combine harvester

Abstract

The invention discloses an ear falling prevention whole-feed combine harvester. An upward inclined grass conveying chain is arranged in the rear of a stem poking roller, an upward inclined threshing roller is mounted at the upper end of the grass conveying chain, a screen, a conveying belt, a fan, a vibrating screen and a bottom screw conveyer are arranged on the lower portion of the threshing roller, the screen is fixed with a baffle plate matched with the grass conveying chain, the baffle close to the end middle of the screen is recessed to form a groove, a baffle plate replacement screen isfixed in the groove, a wind retaining plate matched with the fan is fixed below the baffle plate and connected with the mounting plate, a flow comb is fixed on the mounting plate, and a fixing plateis mounted between the mounting plate and the baffle plate. The combine harvester has the advantages that the threshing roller is obliquely arranged, grains are threshed, kernels and shells can be rapidly separated, a double-box four-gear structure in the grass conveying chain cannot be locked, and the combine harvester is provided with the baffle plate, so that rapeseed stems, long ears and wheatears cannot fall when the combine harvester harvests crops.

Description

technical field [0001] The invention relates to harvester equipment, in particular to a fully threshing and full-feeding combine harvester. Background technique [0002] In the south of our country, planting rice is a traditional habit of people. Usually, people can only do it by hand when harvesting, which is labor-intensive and inefficient. With the development of science and technology, harvesters have appeared in the prior art, which can replace traditional manual work by harvesters. For example, Chinese invention patent, announcement number is 200962742Y, discloses a kind of rice harvester, and it is made up of power mechanism installed on the body, walking mechanism, harvesting mechanism and operating mechanism. The design of the harvester in the above-mentioned prior art is unreasonable, and has the following disadvantages: 1. It can only harvest rice crops, and it is very difficult to harvest rapeseed; 1. The threshing mechanism is usually placed horizontally, whic...

AI Technical Summary

Problems solved by technology

The design of the harvester in the above-mentioned prior art is unreasonable, and has the following disadvantages: 1. It can only harvest rice crops, and it is very difficult to harvest rapeseed; 1. The threshing mechanism is usually placed horizontally, which is not conducive to the output of grain; 4. Between the screen under the threshing roller and the vibrating screen, the fan blows straw, which causes serious waste of grain; There is a lot of grass mixed in, it is not clean; and the structure is complicated, the cost is high, and it is generally unacceptable by people

However, since the starting position of the threshing roller is the same as that of the sieve, some incompletely threshed rice or rapeseeds fall off the sieve, resulting in incomplete threshing
