Abstract
The utility model discloses a longitudinal axial-flow type grain threshing device which is installed between the rear portion of a gap bridge and a gearbox of a grain combine-harvester. The grain threshing device comprises two parallel threshing rollers which are longitudinally arranged with front side low and rear side high and used for threshing and separating, the external circumference surface of each threshing roller is provided with threshing teeth, and the two threshing rollers are driven to rotate by the gearbox of the harvester. Compared with the prior art, the two threshing rollers of the grain threshing device are longitudinally arranged, crops are directly fed between the threshing rollers to be threshed and separated after passing through a header gap bridge, the moving direction of the crops does not need to be changed, the forced threshing and separating to the crops by the threshing rollers are weakened, crushing can be reduced, and meanwhile due to the fact that the crops are repeatedly rotated and threshed inside the threshing rollers, broad spectrum harvesting of crops can be achieved by adjusting the rotating speed of the two threshing rollers according to different crops.
Description
Technical field
The utility model relates to farm machinery, and specifically, the utility model relates to a kind of longitudinal axis streaming grain threshing device.
Background technology
the threshing cylinder of the grain threshing device on present grain combine is lateral arrangement all generally, even threshing cylinder is vertically arranged, all increase in the front portion of threshing cylinder and force threshing cylinder, will cause like this cereal internal injury in by the threshing separation process larger, especially corn percentage of damage when directly carrying out the threshing results is higher, and the grain header that uses this sheller unit can't be realized the results of various crop simultaneously, the results kind is single, the grain header whole economic efficiency is relatively not high, therefore a kind ofly can reduce crop and damage with expecting per family, and realize the grain threshing device to the wide spectrum harvesting of Different Crop.
The utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can reduces crop damage and can realize the longitudinal axis streaming grain threshing device that the wide spectrum to Different Crop gathers in.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of longitudinal axis streaming grain threshing device, be arranged between the gap bridge rear portion and gearbox on grain combine, grain threshing device comprise two that parallel, for vertically arranging and low early and high after being used for the threshing cylinder that threshing separates, the outer circumference surface of threshing cylinder is provided with threshing tooth, and two threshing cylinders drive rotation by the gearbox on grain header.
Described threshing tooth is spike.
The utility model adopts technique scheme, compared with prior art, two threshing cylinders of grain threshing device are vertically arranged, directly carrying out threshing after crop passes a bridge by the ceding of Taiwan between threshing drum feed separates, the direction of motion of crop does not need to change, threshing cylinder weakens the pressure threshing separation of crop, can reduce fragmentation, simultaneously crop threshing repeatedly in threshing cylinder, can realize by the rotating speed of adjusting two threshing cylinders the wide spectrum results of crop for the inhomogeneity crop.
Description of drawings
Fig. 1 is that grain threshing device of the present utility model is arranged on the structure chart on grain header;
Mark in above-mentioned figure is: 1, threshing cylinder; 2, gearbox; 3, pass a bridge.
Embodiment
A kind of longitudinal axis streaming of the utility model grain threshing device, be arranged between gap bridge 3 rear portions and gearbox 2 on grain combine, as shown in Figure 1, this grain threshing device comprise two that parallel, for vertically arranging and low early and high after being used for the threshing cylinder 1 that threshing separates, the outer circumference surface of threshing cylinder 1 is provided with threshing tooth, threshing tooth is spike, and two threshing cylinders 1 drive rotation by the gearbox 2 on grain header, gearbox 2 and can complete adjustment to threshing cylinder 1 rotating speed.Grain header is when work, crop enters threshing cylinder 1 after through the ceding of Taiwan, 3 conveyings of passing a bridge, threshing cylinder 1 and feeding cone, drum cover, notch board form the threshing of the threshing separation chamber jointly completing crops such as corn, soybean and wheats and separate, rotating speed is adjusted by the gearbox 2 at rear portion, by changing corn, soybean and the wheat ceding of Taiwan, can realize the results to corn, soybean, wheat and paddy rice.
Compared with prior art, two threshing cylinders 1 of this grain threshing device are vertically arranged, crop carries out threshing and separates by the ceding of Taiwan 31 of the rear direct threshing drum feed of passing a bridge, the direction of motion of crop does not need to change, the pressure threshing separation of 1 pair of crop of threshing cylinder weakens, can reduce fragmentation, simultaneously crop threshing repeatedly in threshing cylinder 1, can realize by the rotating speed of adjusting two threshing cylinders 1 the wide spectrum results of crop for the inhomogeneity crop.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (2)
1. longitudinal axis streaming grain threshing device, be arranged between the gap bridge rear portion and gearbox on grain combine, it is characterized in that: described grain threshing device comprise two that parallel, for vertically arranging and low early and high after being used for the threshing cylinder that threshing separates, the outer circumference surface of threshing cylinder is provided with threshing tooth, and two threshing cylinders drive rotation by the gearbox on grain header.
2. longitudinal axis streaming grain threshing device according to claim 1, it is characterized in that: described threshing tooth is spike.
