Abstract

The utility model relates to a harvesting machine component, in particular to an overhead axial flow type threshing system for a harvesting machine, which comprises a rolling tube, a conveying component and a support frame, wherein the conveying component is positioned above the outer side of the rolling tube and consists of a stem press plate and a conveying chain, the stem press plate is arranged on a rolling tube cover, the conveying chain of the conveying component is arranged on the support frame, secondary threshing nails comprise nail bodies and screw nuts, each nail body is in a triangular shape, and a section of a screw rod matched with each screw nut extends out from the bottom edge of the triangle. Compared with the traditional underlying threshing system, the overhead axial flow type threshing system adopts a mode of raising the height by the conveying component, so grains can pass through a position above the rolling tube and are threshed. Under the condition, ears of the grains naturally fall down, angles formed between the ears of the grains and the moving directions of the threshing nails arranged on the rolling tube are very favorable for the grain threshing, excessive broken ears can also be avoided, and the threshing is more thorough.

Description

Put the axial-flow type threshing system on the grain header
Technical field
The utility model relates to a kind of grain header parts, is specifically related to put on a kind of grain header the axial-flow type threshing system.
Background technology
As shown in Figure 1, existing threshing system is mainly formed the structure more complicated by threshing cylinder a, threshing auxiliary cylinder b, concave grate c and cane transfer unit d.Because the cane transfer unit d of this underneath type system is from threshing cylinder a side on the lower side, cereal be with cane transfer unit d from the below of threshing cylinder a through and by threshing., inconsistent under this structure with the threshing tooth direction of motion on the threshing cylinder a because the fringe head of cereal is sagging, cause the fringe head to be easy to fracture.Most foreign material impouring concave grate and piling up, very easily result in blockage, cause a large amount of grain can not pass through concave grate, drop on foreign material on the contrary, and together discharge with the foreign material cane, 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 purpose of the utility model is a said problem above being directed against, and provides a kind of structure simpler, and is difficult for obstruction, threshing harvester threshing system more completely.
The utility model is achieved through following technical scheme.
Put the axial-flow type threshing system on a kind of, comprise cylinder, transfer unit, support, wherein: said transfer unit is in the side on the upper side in the cylinder outside; Said transfer unit is made up of cane pressing plate and carrier chain; The cane pressing plate is installed on the drum cover, and the carrier chain of transfer unit is rack-mount, and said secondary threshing nail comprises nail body and nut; Said nail is as triangle, and one section screw rod that matches with nut is stretched out on the triangle base.
The beneficial effect of the utility model is: compare with traditional underneath type threshing system, the utility model adopts the mode of transfer unit hoisting depth, makes cereal from the top process of cylinder and by threshing.In this case, the fringe head of cereal hangs down naturally, and the angle of following closely direction of motion formation with the threshing on the cylinder extremely helps grain threshing, also can avoid too much disconnected fringe, makes threshing more thorough.Owing to put on the cereal, make that on the concave grate below the cylinder, installing secondary threshing nail additional becomes possibility.
Description of drawings
Fig. 1 is existing grain header overhead axial threshing system architecture sketch map.
Fig. 2 is the structural representation of the utility model.
Among the figure, threshing cylinder a, threshing auxiliary cylinder b, concave grate c, cane transfer unit d, drum cover 2, cylinder 1, transfer unit 3, cane pressing plate 31, carrier chain 32, concave grate 4, support 5.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1, put the axial-flow type threshing system on existing and mainly form the structure more complicated by threshing cylinder a, threshing auxiliary cylinder b, concave grate c and cane transfer unit d.Because the cane transfer unit d of this overhead system is from threshing cylinder a side on the lower side, cereal be with cane transfer unit d from the below of threshing cylinder a through and by threshing.
As shown in Figure 2; Put the axial-flow type threshing system on the grain header; Comprise cylinder 1, transfer unit 3, support 5, wherein: said transfer unit 3 is in the side on the upper side in cylinder 1 outside, and said transfer unit 3 is made up of cane pressing plate 31 and carrier chain 32; Cane pressing plate 31 is installed on the drum cover 2, and the carrier chain 32 of transfer unit 3 is installed on the support 5.
