Abstract
The invention relates to a harvester member, in particular to an overhead axial flow type threshing system of a harvester. The overhead axial flow type threshing system comprises a roller, a conveying member and a bracket, wherein the conveying member is arranged slightly above the external side of the roller and consists of a stem press plate and a conveying chain; the stem press plate is installed on a roller cover; the conveying chain of the conveying element is installed on the bracket; a secondary threshing nail comprises a nail body and a nut; the nail body is shaped as a triangle; and a section of a screw rod matched with the nut is stretched out of the bottom margin of the triangle. Compared with the traditional underlying threshing system, in the invention, the conveying member is adopted to raise the height so that grain crops pass through the upper side of the roller and are threshed. Under the circumstances, ear heads of the grain crops fall naturally and form angles beneficial to threshing grain crops with the movement direction of the threshing nail on the roller, so that excess broken ear heads are avoided and the threshing is more thorough.
Description
Technical field
The present invention relates to a kind of grain header parts, be 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 for threshing cylinder a side on the lower side, cereal be with cane transfer unit d from the below of threshing cylinder a by 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 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.
Put the axial-flow type threshing system on a kind of, comprise cylinder, transfer unit, support, wherein: described transfer unit is in the side on the upper side in the cylinder outside, described transfer unit is made of cane pressing plate and carrier chain, the cane pressing plate is installed on the drum cover, the rack-mount described secondary threshing nail of the carrier chain of transfer unit 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.
Beneficial effect of the present invention is: compare with traditional underneath type threshing system, the present invention 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 installing secondary threshing nail on the concave grate below the cylinder additional becomes possibility.
Description of drawings
Fig. 1 is existing grain header overhead axial threshing system architecture schematic diagram.
Fig. 2 is a structural representation of the present invention.
Among the figure, threshing cylinder a, threshing auxiliary cylinder b, concave grate c, cane transfer unit d, drum cover 1, cylinder 2, transfer unit 3, cane pressing plate 31, carrier chain 32, concave grate 4.
Embodiment
Further specify the present invention 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 for threshing cylinder a side on the lower side, cereal be with cane transfer unit d from the below of threshing cylinder a by and by threshing.
As shown in Figure 2, put the axial-flow type threshing system on a kind of grain header, comprise cylinder 1, transfer unit 2, support 3, wherein: described transfer unit 2 is in the side on the upper side in cylinder 1 outside, described transfer unit 3 is made of cane pressing plate 31 and carrier chain 32, cane pressing plate 31 is installed on the drum cover 4, and the carrier chain 32 of transfer unit 3 is installed on the support 5.
Claims (1)
1. put the axial-flow type threshing system on a grain header, comprise cylinder (1), transfer unit (2), support (3), it is characterized in that: described transfer unit (2) is in the side on the upper side in cylinder (1) outside, described transfer unit (3) is made of cane pressing plate (31) and carrier chain (32), cane pressing plate (31) is installed on the drum cover (4), and the carrier chain (32) of transfer unit (3) is installed on the support (5).
