Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art inventive concept of the present utility model, technical scheme are had more complete, accurate and deep understanding.
As shown in Figure 1 to Figure 3, the utility model provides a kind of transmission device of threshing cylinder, comprises a break-in transmission case 1 and one group of variable-speed pulley.Variable-speed pulley comprises driving wheel 2 and follower 3, and the two is by belt 4 transmissions.
The rotating shaft of follower 3 is coaxial with the power shaft 5 of break-in transmission case 1, the output shaft 6 of break-in transmission case 1 and the power shaft 5 vertical effects that realize the break-in transmission.The output shaft 6 of break-in transmission case 1 is coaxial with threshing cylinder.
Described driving wheel 2 and follower 3 all comprise fixed wheel dish 7 and the axially movable runner disc 8 that is fixed in self rotating shaft.Runner disc is provided with internal tooth in the part that is connected with the rotating shaft of belt pulley, and the rotating shaft of belt pulley is provided with the internal tooth chute that matches with described internal tooth.Fixed wheel dish 7 all is truncated cone-shaped with runner disc 8, and the fixed wheel dish 7 on the same belt pulley is relative with the top of runner disc 8.Runner disc 8 can move axially, and the part between the side of the side of runner disc 8 and fixed wheel dish 7 has formed the belt grooves that adapts with belt 4.
The runner disc 8 of driving wheel 2 is provided with axial displacement adjusting device 10, with the position of runner disc 8 in rotating shaft of control driving wheel 2.And be provided with stage clip 9 at the runner disc 8 of follower 3, and an end of stage clip 9 is fixed on the runner disc 8 of follower 3, and the other end is fixed in the rotating shaft of follower 3.
During use, increase the rotating speed of threshing cylinder if desired, only need to adjust described axial displacement adjusting device 10, make the runner disc 8 of driving wheel 2 near the fixed wheel dish 7 of driving wheel 2, will make belt grooves away from rotating shaft, increase the diameter of driving wheel 2 belt grooves.Because belt 4 length fix, so the runner disc 8 of follower 3 is subjected to the effect of belt 4, and move towards the direction away from the fixed wheel dish 7 of follower 3, stop mobile until the runner disc 8 of driving wheel 2.The diameter of the belt grooves of driving wheel 2 increases at this moment, and the belt grooves diameter of follower 3 reduces, and makes the rotating speed of threshing cylinder improve.
Similar, reduce the rotating speed of threshing cylinder if desired as long as court adjusts axial displacement adjusting device 10 away from the direction of the fixed wheel dish 7 of driving wheel 2, just can reduce driving wheel 2 belt grooves.And under the effect of the stage clip 9 that installs by way of compensation, runner disc 8 meetings of follower 3 are near the fixed wheel dish 7 of follower 3, thus the belt grooves of increase follower 3.The also corresponding reduction of rotating speed of threshing cylinder at this moment.
This transmission device has been realized the infinitely variable speeds of threshing cylinder rotating speed easily and reliably thus, and can satisfy Different Crop or with the different conditions of a kind of crop to the quick-adjustsing requirement of drum rotation speed.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
