Description
Technical field
The present invention relates to a kind of threshing performance adjustment section parts, more particularly, to a kind of concave clearance adjustment mechanism.
Background technique
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 is adjusted according to by operating conditions such as de- crop species, feed quantity, moisture content
Gap, to obtain ideal threshing performance.Existing concave clearance adjustment mechanism is usually one lateral edge cylinder shaft line side of notch board
It is fixed to hinged, the notch board other side passes through adjustable draw rod and connects.Changed by adjustable draw rod length scale, between realization notch board
The adjustment of gap.Concave clearance adjusted is inconsistent along roll circumference direction size variation, exists and adapts to various operating conditions
The problem of property is not strong, cannot get ideal threshing performance.
Summary of the invention
The purpose of the present invention is providing for the existing above problem, one kind is adaptable, is conducive to obtain ideal threshing
The concave clearance adjustment mechanism of performance.
To achieve the above object, the present invention adopts the following technical solutions: concave clearance adjustment mechanism of the invention, including de-
The notch board below the threshing cylinder is arranged in grain roller and package, further includes clearance adjustment mechanism, the clearance adjustment mechanism is by adjusting
Whole oil cylinder, main oscillating rod, main tie, connecting rod, secondary oscillating rod, intermediate draw bar, subtie composition, the main oscillating rod are designed as triangle
The left apex angle of shape, the tailpiece of the piston rod for adjusting oil cylinder and the main oscillating rod is point articulated, and the right corner point of the main oscillating rod is hinged on machine
On frame, the point articulated setting main tie of the lower apex angle of the main oscillating rod and connecting rod, the main tie lower end and the notch board curved end
Front end is hinged, and hingedly on the rack, the connecting rod outer end and intermediate draw bar upper end concurrent are hinged in the pair oscillating rod secondary oscillating rod
In portion, which is hinged on the back segment of the notch board curved end, which is hingedly arranged subtie,
The subtie lower end and the rear end of the notch board curved end are hinged.
After adopting the above technical scheme, concave clearance adjustment mechanism provided by the invention has the beneficial effect that
The present invention is when adjusting concave clearance, if the piston rod of the adjustment oil cylinder is protruding, in main oscillating rod, connecting rod
Under the action of, main tie, intermediate draw bar, subtie synchronization action are close to threshing cylinder by notch board pull-up, keep concave clearance same
Step reduces, and obtains synchronizing consistent ideal concave clearance.If conversely, the inwardly retraction of the piston rod of the adjustment oil cylinder, notch board
Gap, which will synchronize, to become larger.Various threshing operations condition requirements are thus adapted to, and Threshing is good.Adaptability is obtained
By force, be conducive to obtain the effect of ideal threshing performance.

Specific embodiment
Present invention is further described in detail with reference to the accompanying drawings and detailed description:
As shown, giving the specific embodiment organigram of concave clearance adjustment mechanism of the present invention, including de-
Notch board 7 below the threshing cylinder 6 is arranged in grain roller 6 and package, further includes clearance adjustment mechanism, the clearance adjustment mechanism by
It adjusts oil cylinder 1, main oscillating rod 2, main tie 3, connecting rod 4, secondary oscillating rod 5, intermediate draw bar 8, subtie 9 to form, the main oscillating rod 2
It is designed as triangle, the left apex angle for adjusting the tailpiece of the piston rod and the main oscillating rod 2 of oil cylinder 1 is point articulated, the right top of the main oscillating rod 2
Angle point hingedly on the rack, the point articulated setting main tie 3 of the lower apex angle of the main oscillating rod 2 and connecting rod 4,3 lower end of main tie with
The front end of 7 curved end of notch board is hinged, and secondary oscillating rod 5 is hinged on the rack, and 4 outer end of connecting rod and 8 upper end of intermediate draw bar are total
It is point articulated on 5 middle part of the pair oscillating rod, which is hinged on the back segment of 7 curved end of notch board, which puts
Subtie 9 is hingedly arranged in 5 outer end of lever, and 9 lower end of subtie and the rear end of 7 curved end of notch board are hinged.
In use, concave clearance adjustment mechanism is left and right symmetrically arranged at the both ends of the threshing cylinder 6, it is recessed when needing to adjust
When sheet separation, 1 synchronization action of adjustment oil cylinder at both ends is controlled.If the piston rod of the adjustment oil cylinder 1 is protruding, in main pendulum
Lever 2, connecting rod 4 linkage effect under, 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, makes concave clearance is synchronous to reduce, obtains synchronizing consistent ideal concave clearance., whereas if by the adjustment oil cylinder
1 piston rod inwardly retracts, and concave clearance, which will synchronize, to become larger.
The configuration of the present invention is simple, manipulation is convenient, can implement the accurate adjustment of concave clearance.
