Abstract
The utility model provides a structure of a threshing mechanism of a rice-wheat threshing machine, and the main structure is formed by a threshing cylinder abutting upon a thrusting and rubbing device. The threshing cylinder comprises an inner lining cylinder, a filler interlayer and an excircle surface layer, wherein, the excircle surface layer is made of flexible wear resistant material, the surface is rough; the inner lining cylinder is made of rigid material, and the filler in the interlayer is made of elastic and flexible materials. Compared with the prior art, the utility model has the advantages that the structure can cause grain and wheat spikes to be threshed under the thrusting and rubbing of the threshing cylinder and the thrusting and rubbing device, so that the kernels are separated from straws, and the kernels cannot be crushed.
Description
Affiliated technical field
The utility model relates to a kind of rice-wheat thresher, is specially the structure of rice-wheat thresher sheller unit.
Background technology
The threshing of existing rice-wheat thresher mainly is the mode of hitting grain or wheat by threshing cylinder down, and shortcoming is in threshing, and with more straw, standing grain leaf etc., the paddy wheat is difficult to separate, and causes labour's waste.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of structure of the rice-wheat thresher sheller unit that the paddy wheat can be separated with straw etc. in threshing is provided.
The measure that realizes above-mentioned purpose is: the utility model squeezes twist device by threshing cylinder near one and constitutes; Described threshing cylinder comprises liner cylinder, filler interlayer and cylindrical top layer, and the cylindrical top layer is made by shaggy flexible wear-resistant material, and the liner cylinder is made by rigid material, and the filler in the interlayer is that elasticity and flexible material are made.
The utility model has two kinds of specific embodiments at least:
As one of specific embodiments, described crowded twist device is a cylinder, this cylinder comprises liner cylinder, filler interlayer and cylindrical top layer, the cylindrical top layer is made by shaggy flexible wear-resistant material, the liner cylinder is made by rigid material, and the filler in the interlayer is that elasticity and flexible material are made, and does not stay the slit between threshing cylinder and this cylinder, during threshing, two cylinders are done rotation in opposite directions.
As two of specific embodiments; described crowded twist device is the crowded washboard of one section arc; should squeeze washboard and comprise inner arc surface; filler interlayer and external arc; inner arc surface is made by shaggy flexible wear-resistant material; external arc is made by rigid material; filler in the interlayer is that elasticity and flexible material are made; crowded washboard is fixed on the thresher frame; its inner arc surface is near the cylindrical top layer of threshing cylinder; and cylindrical leaves the slit between the top layer; and one inclined-plane is set at an end that squeezes washboard, form the charging aperture of one " V " font between this inclined-plane and the threshing cylinder.
Advantage of the present utility model is: the threshing under the crowded stranding of threshing cylinder and crowded twist device of standing grain (wheat) fringe separates with straw etc., the paddy wheat passes through from threshing cylinder and crowded twist device, and straw etc. are detained, thereby paddy rice wheat is separated from straw, because of the flexible interlayer of sheller unit, so the paddy wheat can be by crowded broken.
