The difference of species, the humidity of cereal difference, the not equal a variety of causes of pace of harvesting, we can be according to specific circumstances
To adjust the size of cylinder-concave clearance, so as to ensure the quality of grain harvest.
Regulation of the existing sheller unit to cylinder-concave clearance is confined to the replacing to notch board or the regulation using pull bar, and
The mode complicated mechanism of pull bar regulation, regulation cylinder-concave clearance mode is not enough facilitated.
The content of the invention
There is provided a kind of sheller unit of adjustable cylinder-concave clearance to overcome the deficiencies in the prior art by the present invention.Such a threshing
Device can adjust the size of cylinder-concave clearance according to actual production harvest situation, overcome original sheller unit cylinder-concave clearance
Regulation difficulty and the low problem of automaticity.
The technical solution adopted by the present invention is：A kind of sheller unit of adjustable cylinder-concave clearance, including fuselage, threshing cylinder,
Notch board, slack adjuster；Wherein notch board includes preceding notch board, intermediate recessed plate, rear notch board, rotating shaft；Wherein slack adjuster bag
Include sliding block, guide rail, hydraulic jack.The notch board is located at below threshing cylinder；The slack adjuster is located at four of notch board
On angle；The fuselage is located at outside threshing cylinder and notch board；The preceding notch board and rear notch board are all joined by rotating shaft and intermediate recessed plate
Connect；Notch board is all connected by rotating shaft with sliding block before and after described；The sliding block is through guide rail and is connected by bolts and hydraulic jack
It is connected；The hydraulic jack is connected by bolts to be connected with fuselage.
Further, it is connected before, during and after the notch board is divided between three part notch boards, two parts notch board by rotating shaft
Connect, the two ends of rotating shaft are provided with pin-and-hole, and notch board is fixed in rotating shaft by split pin, each section notch board can revolve around the shaft
Turn；Before, during and after three part notch boards cause notch board integrally have certain flexibility, can avoid to a certain extent in sheller unit
The blocking of maslin, reduces the probability of failure of machine.
Further, the slack adjuster has four groups of adjusting meanss and collectively constituted, and they are located at the four of notch board respectively
On individual angle, each section slack adjuster is all made up of sliding block, guide rail, hydraulic jack, when the oil pressure in hydraulic jack changes
When, hydraulic jack can band movable slider be slided on guide rail, so as to change the height of notch board, so change threshing cylinder and notch board it
Between gap length；When two groups of the front adjusting means and two groups of rear adjusting means of notch board can be different or different degrees of regulation
The height of front and rear both sides notch board, so that there is different size of cylinder-concave clearance on both sides before and after sheller unit；Combining
Hydraulic system is equipped with machine, the mode of hydraulic regulation can be very easily met.
The beneficial effects of the invention are as follows：It is simple in construction, it is easy to manufacture；The adjusting means is adjusted using hydraulic-driven
Section, effectively can easily adjust cylinder-concave clearance, simple to operate, and reliability is high, can effectively ensure that the threshing quality of sheller unit；
The notch board is made up of three parts, with certain flexibility, it is possible to prevente effectively from accumulation of the maslin in sheller unit,
Block, it is ensured that the normal work of sheller unit；Meanwhile, when notch board partial destruction, the notch board structure of three-stage makes it easy to
Change, and can partly change, it is cost-effective.
