Description
Technical field
The present invention relates to agricultural mechanical field, in particular to a kind of dual-sided board combination clamps the adjustable threshing dress of cylinder-concave clearance
It sets and combined harvester.
Background technique
Threshing is the important link in agricultural production, and material is needed to separate seed from glume after harvesting, be obtained
To the mixture of seed and glume, prepare further to clean.When field harvests, cereal is cut combined harvester by the ceding of Taiwan
Under, it is fed into installed threshing separator through intermediate conveying device, is generated in the case where threshing cylinder high speed is hit with concave grate and is squeezed, rubs
It rubs with the hands, curry, colliding and realize threshing, the grain taken off is separated from notch board sieve pore, cleaned into subsequent, a large amount of complete stalks
It is discharged outside machine.When work harvest, feed quantity can be fluctuated with the distribution density difference of field crops, this directly results in de-
The load of grain roller can change, and not only result in separation efficiency for threshing reduction, blocking is resulted even in when serious.Therefore,
Combined harvester cylinder-concave clearance regulating device is studied to prevent threshing cylinder from blocking, can be improved the work effect of combined harvester
Rate, Performance And Reliability have important theory significance and practical value.Current scientific research personnel both domestic and external is also between notch board
The regulating mechanism and device of gap have carried out some researchs and invention.
The patent of invention of China discloses a kind of multiple-roll combined harvester concave clearance automatic adjustment installed threshing separator
And adjusting method, including rack, flow-cut threshing cylinder, monoblock type concave grate, concave clearance adjusting system, transverse-axis-flow stream threshing roll
Cylinder can be carried out by detecting to the pressure on monoblock type concave grate by data of the data Collection & Processing System to acquisition
Processing and analysis adjust concave clearance for combining by hydraulic push rod according to generating feedback signal and being transferred to solenoid directional control valve
The monoblock type concave grate pressure detecting of installed threshing separator and the adaptive adjustment of concave clearance when cropper field harvests, inspection
Measurement equipment is at low cost, easy for assemble or unload.But it is integrally-regulated to notch board progress by hydraulic push rod, on the one hand since monoblock type is recessed
Plate own wt is larger, needs to consume biggish energy；On the other hand due to adjusting to notch board monoblock type, notch board difference is changed
Position distance in the circumferential direction, keeps concave clearance inconsistent along roll circumference direction size variation, may result in threshing not
Uniformly.
The patent of invention of China discloses a kind of grain threshing roller concave clearance self-checking device and adjusting method, wraps
Include that top cover, threshing cylinder, concave grate, driving motor, rack, stress acquisition module and signal receive and processing system, using pair
Stress on threshing toothed bar carries out detection and Data Management Analysis, by feedback signal transmission to driving motor and realizes threshing cylinder
Concave clearance automatic adjustment.The invention can be used for the threshing toothed bar stress inspection of installed threshing separator when the harvest of combined harvester field
Survey and the adaptive adjustment of concave clearance, but the regulative mode is the sheller unit of spike-tooth for threshing toothed bar, has one
It settles finally sex-limited；And regulative mode is the increase that cylinder-concave clearance is realized by the rotation to notch board side, will lead to notch board after adjustment
Gap is inconsistent along roll circumference direction size variation, if rotation angle is spent greatly, may result in because cylinder-concave clearance is excessive
Caused threshing is not clean；If rotating angle too small, it may result in roller side and result in blockage, and then new ask can be caused
Topic.
Different concave clearance regulating devices is proposed in the above-mentioned published patent, it, can root during actual cut
The different factors such as the pressure change according to notch board when the type of cereal, harvest are adjusted cylinder-concave clearance, guarantee grain harvest
Quality also realizes the automation control adjusted for cylinder-concave clearance to a certain extent.But it is existing to cylinder-concave clearance adjust
Research main thought is integrally-regulated to notch board progress, at present mainly includes that the synchronous up and down adjustment in notch board two sides is adjusted with unilateral rotation
Section.The synchronous up and down adjustment in two sides is usually to rely on multiple hydraulic cylinders to realize the adjusting of notch board, realizes that difficulty is relatively high,
It is not easy to realize finer adjusting；Unilateral side rotation adjusts usually that a lateral edge cylinder shaft line direction of notch board is hingedly solid
Fixed, the notch board other side is connected in link mechanism, gear/rack mechanism or hydraulic mechanism, by between the rotation realization notch board of notch board
The adjustment of gap, since transmission mechanism is relatively complicated, it is not convenient enough to adjust, and after rotating adjustment concave clearance along roll circumference
Direction size variation is inconsistent, not strong to various operating condition adaptability, influences threshing performance.
