Description
Technical field
The present invention relates to a kind of threshing performance adjustment portion part, more particularly, to a kind of concave clearance adjustment mechanism.
Background technology
Sheller unit mainly includes threshing cylinder, notch board and concave clearance adjustment mechanism, and sheller unit is in the course of work
In, the workplace between threshing cylinder and notch board to be adjusted according to by operating conditions such as de- crop species, feed quantity, moisture content
Gap, to obtain preferable threshing performance.Existing concave clearance adjustment mechanism is usually along threshing cylinder axis side notch board side
To fixation is hinged, notch board opposite side is connected by adjustable draw rod.Changed by adjustable draw rod length scale, realized between notch board
The adjustment of gap.Concave clearance after adjustment is inconsistent along roll circumference direction size variation, exists and various operating conditions are adapted to
Property not strong, cannot preferable threshing performance problem.
Content of the invention
The purpose of the present invention is for the problems referred to above for existing, there is provided a kind of strong adaptability, be conducive to obtaining preferable threshing
The concave clearance adjustment mechanism of performance.
For achieving the above object, the present invention adopts following technical proposals：The concave clearance adjustment mechanism of the present invention, including de-
Grain cylinder and parcel are arranged on notch board below the threshing cylinder, also include clearance adjustment mechanism, and the clearance adjustment mechanism is by adjusting
Whole oil cylinder, main swing arm, main tie, connecting rod, secondary swing arm, intermediate draw bar, subtie composition, the main swing arm are designed as triangle
Shape, the tailpiece of the piston rod for adjusting oil cylinder are point articulated with the left drift angle of the main swing arm, and the right corner point of the main swing arm is hinged on machine
On frame, the lower drift angle of the main swing arm is point articulated to arrange main tie and connecting rod, the main tie lower end and the notch board curved end
Front end is hinged, and secondary swing arm is hinged in frame, and the connecting rod outer end and intermediate draw bar upper end concurrent are hinged in the secondary swing arm
In portion, the intermediate draw bar lower end is hinged on the back segment of the notch board curved end, and the secondary swing arm outer end is hinged setting subtie,
The subtie lower end is hinged with the rear end of the notch board curved end.
After using above-mentioned technical proposal, the concave clearance adjustment mechanism that the present invention is provided has an advantageous effect in that：
The present invention adjust concave clearance when, if the piston rod of the adjustment oil cylinder is protruding, in main swing arm, the work of connecting rod
With under, main tie, intermediate draw bar, subtie synchronization action will be close to threshing cylinder for notch board pull-up, make concave clearance synchronously contract
Little, obtain synchronous consistent preferable concave clearance.If conversely, the inwardly retraction of the piston rod of the adjustment oil cylinder, concave clearance
Will synchronously become big.Thus adapt to various threshing operations conditions to require, and Threshing is good.Obtained strong adaptability,
Be conducive to the effect for obtaining preferable threshing performance.

Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in further detail：
As illustrated, the specific embodiment organigram of concave clearance adjustment mechanism of the present invention is given, including threshing roll
Cylinder 6 and parcel are arranged on notch board 7 below the threshing cylinder 6, also include clearance adjustment mechanism, and the clearance adjustment mechanism is by adjusting
Oil cylinder 1, main swing arm 2, main tie 3, connecting rod 4, secondary swing arm 5, intermediate draw bar 8, subtie 9 are constituted, and the main swing arm 2 is designed
For triangle, the tailpiece of the piston rod for adjusting oil cylinder 1 is point articulated with the left drift angle of the main swing arm 2, the right corner point of the main swing arm 2
It is hinged in frame, the lower drift angle of the main swing arm 2 is point articulated to arrange main tie 3 and connecting rod 4, and 3 lower end of main tie is recessed with this
The front end of 7 curved end of plate is hinged, and secondary swing arm 5 is hinged in frame, 8 upper end concurrent hinge of 4 outer end of connecting rod and intermediate draw bar
On being connected in the middle part of the secondary swing arm 5,8 lower end of intermediate draw bar is hinged on the back segment of 7 curved end of notch board, the secondary swing arm
5 outer ends are hinged setting subtie 9, and 9 lower end of subtie is hinged with the rear end of 7 curved end of notch board.
During use, concave clearance adjustment mechanism is left and right symmetrically arranged at the two ends of the threshing cylinder 6, recessed when needing to adjust
During sheet separation, 1 synchronization action of adjustment oil cylinder at two ends is controlled.If will be protruding for the piston rod of the adjustment oil cylinder 1, in main pendulum
Under lever 2, the linkage effect of connecting rod 4, main tie 3, intermediate draw bar 8,9 synchronization action of subtie, by 7 pull-up of notch board to threshing roll
Cylinder 6 is close, concave clearance is synchronously reduced, and obtains synchronous consistent preferable concave clearance., whereas if by the adjustment oil cylinder
1 piston rod is inwardly retracted, and concave clearance will synchronously become big.
Present configuration is simple, and manipulation is convenient, can implement the accurate adjustment of concave clearance.
