[0034] Compared with the prior art, the combine harvester provided by the utility model has the following advantages:

[0035] The combine harvester provided by the utility model can harvest crops through the cutting table, and the harvested crops can be transferred downward through the cross auger. Since the output end of the cross auger in this application is docked with the accelerating roller assembly, and the accelerating roller assembly includes a cylinder body and an accelerating roller shaft 14, and the power output of the power mechanism can be transmitted to the accelerating roller shaft 14, the cylinder body can be driven to rotate through the accelerating roller shaft 14.

[0036] By making the material enter the accelerating roller assembly before the axial flow roller assembly, a certain degree of pre-threshing and separation effect can be obtained for the material in the cylinder body. Moreover, the accelerating roller assembly in this application can accelerate the flow rate of the material towards the axial flow roller assembly. Therefore, on the one hand, the material can enter the axial flow roller assembly faster, and on the other hand, it can also be further threshed under the action of the axial flow roller assembly, so as to improve the threshing effect and threshing separation speed to a certain extent, and further improve the operation efficiency of the overall harvester.

[0037] Optionally, as Figure 1 Combined with Figure 2 shown, the separation assembly in this application includes a threshing drive member, and the threshing drive member includes a connecting shaft 3 and transmission wheels 6 arranged at both ends of the connecting shaft 3.

[0038] Through the transmission wheels 6 connected to both ends of the connecting shaft 3 in this application, the power input from the power mechanism can be received through the transmission wheel 6 at one end, so that the transmission wheel 6 at the other end can be rotated through the connecting shaft 3, and further the power can be transmitted downward through the transmission wheels 6 at both ends of the connecting shaft 3. That is, the above-mentioned transmission wheel 6 in this application is in transmission connection with the axial flow roller shaft 4, and through the transmission connection between the axial flow roller shaft 4 and the accelerating roller shaft 14, the power output by the power mechanism can be transmitted to the accelerating roller shaft 14, and finally the rotation of the cylinder body can be driven.

[0039] It can be understood that during actual operation, the material first enters the cylinder body for preliminary threshing and acceleration, then flows into the axial flow roller assembly for further threshing, and finally enters the straw walker set in the harvester for final threshing to complete the overall threshing operation.

[0040] Optionally, as Figure 1 Combined with Figure 2As shown in the figure, the power mechanism in the present application includes an engine, a total output wheel 1, and a transmission member 9; the output end of the engine is connected to the total output wheel 1, and the total output wheel 1 is in transmission connection with a transmission wheel 6 at one end of a connecting shaft 3 through the transmission member 9, and the transmission wheel 6 at the other end of the connecting shaft 3 is in transmission connection with an axial flow drum shaft 4 through the transmission member 9, and the axial flow drum shaft 4 is in transmission connection with an acceleration drum shaft 14 through the transmission member 9.

The cutter bar intermediate shaft 5 can smoothly transmit power stably to the cutter bar transmission shaft 15 to achieve the stability of the overall operation.

[0043] Optionally, as Figure 1 Combined with Figure 2 As shown in the figure, the combine harvester provided by the present utility model further includes a chopping mechanism.

[0050] By connecting the grain lifting shaft 10 with the speed change wheel 7, the power transmitted by the power mechanism can be obtained through the speed change wheel 7, so that the operation of the grain lifting mechanism can be realized, and the threshed grains can be transported to the grain box of the harvester.
