Description
Technical field
The invention belongs to agricultural equipment technology fields, are related to threshing and separating device of combine harvester, particularly a kind of water
Rice combine harvester bias cuts stream just de- separator.
Background technique
Cut flow roller is to connect the important feature of delivery chute feeding and longitudinally axial flow threshing separation barrel, mainly to maturation
Du Gaoyituo seed carries out just de- separation, while the rice after just de- separation being fed into longitudinal axial flow threshing device, work
Performance seriously affects complete machine working performance and harvest quality.
Chinese patent CN201020277026.8 (cutting vertical combined installed threshing separator) discloses one kind and cuts stream threshing dress
It sets, it is solid in the leading portion of longitudinal axial flow roller by the way that check drum is arranged between cut flow roller and longitudinal axial flow roller and by original text transition plates
Feeding auger is set surely, completes threshing work；(combine is double to cut stream and longitudinal direction to Chinese patent CN201120459118.2
Axis stream combines installed threshing separator) a kind of double cut flow roller installed threshing separators are disclosed, which passes through the two of parallel arrangement
A flow-cut threshing cylinder completes the first de- separation of rice；Chinese patent CN20150926643.3 (a kind of centering type thresing machine and its
Harvester) a kind of centering type thresing machine is disclosed, by constructing the gap of size variation between roller and sieve, paddy can be made
Grass obtains maximizing strike rubbing, promotes Threshing；Chinese patent CN201520004957.3 (flexible reversal means formula cell breeding
Wheat taper sheller unit) a kind of threshing cylinder being mounted on eccentric crankshaft is disclosed, which is arranged threshing member
Part, small end face are arranged air flow guide, flexible reversal means are arranged on the eccentric crankshaft on the inside of it, improves threshing efficiency.
It can be seen that being improved by structure is to improve a kind of important way of feeding smoothness, but cutting at vertical stream interface port still
So exist and feeds the problems such as unsmooth, meanwhile, the cornerite of cut flow roller concave grate is 80 °~100 °, in stalk threshing transmission process
Middle rice along cut flow roller circular motion only 1/3 or so so that cut flow roller born during just de-, separation, feeding it is larger
Eccentric load, generate biggish eccentric vibrating, will affect the integral working for cutting flow threshing device and combine harvester, drop
Low service life.
Summary of the invention
For flow threshing device is cut in the prior art, feeding often occur unsmooth cutting at vertical stream interface port, block and rewind compared with
Biggish eccentric load is born during just de-, separation, feeding for serious and cut flow roller, generates biggish eccentric vibrating etc.
Problem, the present invention provides a kind of rice combine bias to cut stream just de- separator, so that threshing element is in longitudinal axial flow
Feeding mouth is nearby withdrawn in threshing cylinder, reduces rewind effect of the threshing element to rice, meanwhile, it is de- to stream is cut using eccentric shaft
Grain roller rotation center generates the moment of resistance that equalising torque part rice generates, and efficiently solves and cuts vertical stream rice combine
Upper cut flow roller alleviates the vibration of flow-cut threshing cylinder to cut feeding that vertical stream intersection occurs unsmooth and the problem of rewind rice
It is dynamic, improve the working performance and service life for cutting flow threshing device and combine harvester.
