Abstract

The invention relates to a component of a harvester, in particular to a secondary threshing system for the harvester. The system comprises a cylinder cover, a cylinder, a conveying part and a concave sieve, wherein the cylinder cover is hinged on a bracket; the cylinder is arranged on the bracket through a shaft and is connected to an engine through a belt wheel arranged on the shaft; the concave sieve is fixedly arranged on the bracket; a stem rod pressing plate of the conveying part is arranged on the cylinder cover; a stem rod conveying chain of the conveying part is arranged on the bracket; and a secondary threshing nail is fixed on the concave sieve. Compared with the traditional threshing system, the secondary threshing system for the harvester has the advantages that the structure is greatly simplified and the manufacturing cost is lowered. The secondary threshing system for harvester is characterized in that the secondary threshing nail is added while a complex secondary threshing assistant cylinder device is abandoned.

Description

A kind of grain header secondary threshing system
Technical field
The present invention relates to a kind of grain header parts, be specifically related to a kind of grain header secondary threshing system.
Background technology
As depicted in figs. 1 and 2, the secondary threshing system of existing half-feeding combine is mainly formed the structure more complicated by threshing cylinder a, secondary threshing auxiliary cylinder b and concave grate c.The threshing cylinder two ends are open, most foreign material impouring vibratory sieve, very easily result in blockage, cause a large amount of grain can not pass through vibratory sieve, drop on foreign material on the contrary, and together discharge with foreign material, caused the waste of grain.And the foreign material that fly upward fly into cleaning and sorting system easily, and cleaning plant is resulted in blockage, and work is cleaned in influence.
Summary of the invention
The objective of the invention is provides a kind of structure simpler at top described problem, and is difficult for obstruction, threshing harvester threshing system more completely.
The present invention is achieved by the following technical programs.
A kind of grain header secondary threshing system comprises drum cover, cylinder, transfer unit and concave grate, and described drum cover is hingedly mounted on the support, and cylinder is rack-mount by axle, and links to each other with engine by the belt pulley that is installed on the axle; Described concave grate is fixedly mounted on the support, and the cane pressing plate of transfer unit is installed on the drum cover, and the cane carrier chain of transfer unit is rack-mount, is installed with secondary threshing nail on the described concave grate.
Described secondary threshing nail comprises nail body and nut, and described nail is as triangle, and one section screw rod that matches with nut is stretched out on the triangle base.
Described secondary threshing nail is equidistant rectangular array on concave grate.
Line and the perpendicular rectangular arrayed of threshing tooth that is listed as on the described cylinder, and staggered with secondary threshing nail.
The tail end of described cylinder is equipped with cylinder spiral Lysimachia sikokiana fan blade.
Beneficial effect of the present invention is: compare with traditional threshing system, the present invention simplifies the structure greatly, reduces manufacturing cost.The present invention has increased secondary threshing nail, and has given up complicated secondary threshing auxiliary cylinder device.After cereal entered cylinder, through the preliminary threshing of cylinder, the disconnected fringe of part, assorted bits rotated with cylinder, strike the secondary threshing nail on the concave grate, carry out the secondary threshing.This threshing mode since secondary threshing nail stop continuous stirring with cylinder, it is outer and brought to the fuselage rear by the cane after the threshing and together discharge to make that the foreign material accumulated on the concave grate all are discharged from threshing bin with the rotation of Lysimachia sikokiana fan blade, alleviated the stopping state of concave grate, the grain that contains in the foreign material is also fallen into concave grate by stirring, improved the threshing performance of cereal, the threshing of cereal is more thorough.
Description of drawings
Fig. 1 is existing harvester threshing system architecture schematic diagram.
Fig. 2 is the right view structural representation of Fig. 1.
Fig. 3 is a structural representation of the present invention.
Fig. 4 is a left view structural representation among Fig. 3.
Fig. 5 is an A part enlarged diagram among Fig. 3.
Among the figure, threshing cylinder a, secondary threshing auxiliary cylinder b, concave grate c, drum cover 1, cylinder 2, transfer unit 3, cane pressing plate 31, carrier chain 32, concave grate 4, secondary threshing nail 5, nail body 51, nut 52, cylinder spiral Lysimachia sikokiana fan blade 6, support 7.
Embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
As depicted in figs. 1 and 2, the threshing system of existing half-feeding combine is mainly formed the structure more complicated by threshing cylinder a, secondary threshing auxiliary cylinder b and concave grate c.Threshing cylinder a two ends are open, most foreign material impouring concave grate c, very easily result in blockage.
As shown in Figure 3 and Figure 4, a kind of grain header secondary threshing system comprises drum cover 1, cylinder 2, transfer unit 3 and concave grate 4, and described drum cover 1 is hingedly mounted on the support 7, cylinder 2 is installed on the support 7 by axle, and links to each other with engine by the belt pulley that is installed on the axle; Described concave grate 4 is fixedly mounted on the support 7, and the cane pressing plate 31 of transfer unit 3 is installed on the drum cover 1, and the carrier chain 32 of transfer unit 3 is installed on the support 7, is installed with secondary threshing nail 5 on the described concave grate 4.
As described in Figure 5, described secondary threshing nail 5 comprises nail body 51 and nut 52, and described nail body 51 is a triangle, and one section screw rod that matches with nut 52 is stretched out on the triangle base.
Described secondary threshing nail 5 is equidistant rectangular array on concave grate 4.
The rectangular arrayed of threshing tooth of line and perpendicular row on the described cylinder 2, and follow closely 5 staggered with the secondary threshing.The tail end of described cylinder 2 is equipped with cylinder spiral Lysimachia sikokiana fan blade 6.
