Abstract
The invention relates to a corn thresher with a low breakage rate for corn threshing. The corn thresher is particularly suitable for the threshing of corn seeds. The corn thresher is composed of a feeding area, a threshing area and a corncob discharging area. The feeding area is placed at the front end of the thresher. The feeding area comprises a feeding box fixed on a shell of the thresher and a feeding spiral blade fixed on a spindle. The feeding spiral blade is in a shape of unequal height. The threshing area is placed on the middle section of the thresher and comprises wide plate teeth fixed on the spindle, a grid concave plate fixed on the shell of the thresher and a fixing baffle. The corncob discharging area is arranged at the tail end of the thresher. The power of the thresher is transmitted by a drive belt pulley and drives the spindle and the feeding spiral blade and the wide plate teeth on the spindle to rotate along with the spindle to push corn clusters putting into the feeding box to enter the threshing area by the feeding spiral blade to thresh, and threshed corncobs are discharged by the corncob discharging area. According to the corn thresher, the problem of the breakage of corn grains can be effectively solved, and the corn clusters are pushed smoothly.
Description
Technical field
The present invention relates to a kind of low percentage of damage husker sheller for corn threshing, be particularly suitable for method of seed corn.
Background technology
Domestic existing husker sheller, mostly adopt the threshing of beating type principle, the percentage of damage of this thresher corn kernel and corncob is all higher.In recent years, squeeze stranding formula husker sheller from the external wide plate tooth introducing digestion, although to a certain extent, overcome the shortcoming of beating type thresher, still there is the fragmentation of seed, can not ignore for corn seed especially.
Summary of the invention
The object of this invention is to provide a kind of husker sheller of low percentage of damage, it squeezes stranding formula thresher to wide plate tooth to improve, namely the plate tooth contacted with corn ear in threshing course and grid type intaglio plate surface are adopted elastomeric material manufacture, make the contact of corn ear and thresher in threshing course, become the contact of elastomeric material and corn ear, thus reduce the fragmentation of corn kernel; Meanwhile, axial for the feed zone helical blade pushing corn ear is made not contour form, successfully to push corn ear in time.
Above-mentioned purpose of the present invention is achieved through the following technical solutions, and accompanying drawings is as follows:
A kind of low percentage of damage husker sheller, be made up of feed zone, threshing zone and Pai Xin district, described feed zone is arranged in the front end of thresher, comprise the material feeding box 2 be fixed on thresher shell 4 and the feeding screw blade 3 be fixed on main shaft 5, described feeding screw blade 3 is not contour form, and blade height gradually changes along main shaft 5 radial direction; Described threshing zone is arranged in the stage casing of thresher, comprises the wide plate tooth 6 be fixed on main shaft 5, is fixed on grid intaglio plate 7 on thresher shell 4 and stationary barrier 8; Described Pai Xin district is arranged in the tail end of thresher, is made up of row's core apparatus 9; The power of described thresher is imported into by drive pulley 1 and drives main shaft 5 and feeding screw blade 3 fixed thereon to rotate with main shaft 5 with wide plate tooth 6; the corn ear promoting to be dropped into by material feeding box 2 enters threshing zone threshing through feeding screw blade 3, and the corncob after threshing is discharged through row's core apparatus 9.
The helical blade height of described feeding screw blade 3 increases to row's core end along main shaft diameter gradually to from feeding end, the axis direction making the corn ear of input not with main shaft 5 axis being parallel, and change to parallel with main-shaft axis in motion process gradually smoothly.
The outer surface that described wide plate tooth 6 and grid intaglio plate 7 contact with corn ear is provided with has flexible flexible material.
Described flexible material is plastics or rubber.
Technique effect of the present invention:
1. because feeding screw blade 3 is not contour form, helical blade height increases to row's core end along main shaft diameter gradually to from feeding end, so just make in the corn ear of input, the axis direction existed not with the fruit ear of main shaft 5 axis being parallel, can change to parallel with main-shaft axis in motion process gradually smoothly, thus reach the effect of low percentage of damage threshing;
2. due to the outer surface that wide plate tooth contacts with corn ear with grid intaglio plate, its material is plastics or rubber, has flexibility when thus contacting with corn ear, therefore less to the damage of corn kernel, thus reaches the effect of low percentage of damage threshing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the husker sheller of the low percentage of damage of the present invention.
Fig. 2 is that feeding screw blade height is along main shaft diameter to the schematic diagram increased gradually to row's core end from feeding end.
Fig. 3 is the A-A profile of Fig. 1.
In figure: 1, drive pulley, 2, material feeding box, 3, feeding screw blade, 4, thresher shell, 5, main shaft, 6, wide plate tooth, 7, grid intaglio plate, 8, stationary barrier, 9, row's core apparatus
Embodiment
Low percentage of damage husker sheller is made up of drive pulley 1, material feeding box 2, feeding screw blade 3, thresher shell 4, main shaft 5, wide plate tooth 6, grid intaglio plate 7, stationary barrier 8 and row's core apparatus 9; material feeding box 2, grid intaglio plate 7, stationary barrier 8 and row's core apparatus 9 are fixed on thresher shell 4; power is imported into by drive pulley 1 and drives main shaft 5 to rotate, and the feeding screw blade 3 be fixed on main shaft 5 rotates with main shaft with wide plate tooth 6.During thresher work; corn ear is dropped into by material feeding box 2; then driven by the feeding screw blade 3 rotated; move perpendicular to main-shaft axis direction in forward direction row core apparatus direction and up and down direction; simultaneously because feeding screw blade 3 is not contour form; helical blade height increases to row's core end along main shaft diameter gradually to from feeding end; so just make in the corn ear of input; the axis direction existed not with the fruit ear of main shaft 5 axis being parallel, can change to parallel with main-shaft axis in motion process gradually smoothly.After corn ear enters threshing zone, due to wide plate tooth 6 and the acting in conjunction of grid intaglio plate 7, the squeezed stranding of the seed on corn ear is fallen, thus reaches the object of threshing.Due to the outer surface that wide plate tooth contacts with corn ear with grid intaglio plate, its material is plastics or rubber, has flexibility when thus contacting with corn ear, less to the damage of corn kernel.
