Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power transmission device for a combine harvester. In the case of a combine that is equipped with a transfer device between the front reaping device and the rear threshing device to transfer the harvested grain culm to the threshing device, the front side of the threshing device is covered with the upper side by the transfer device. It is narrow and has a complicated structure. Therefore, when a prime mover is mounted on the side of the tip of the grain culm to be transferred at the front of the threshing device and is linked to each of these threshing devices, reaping devices, traveling devices, etc.,
If the interlocking mechanisms for these various parts are located closer to the tip side, disassembling, assembling, correcting, and other operations for these interlocking mechanisms are troublesome and likely to be dangerous.

The present invention takes the following technical measures to eliminate such drawbacks. That is, a threshing device 2 that inherits the grain harvested by the front reaping device 1 and threshes the grain while transferring it to the rear is placed on one side, a prime mover 3 is placed on the other side, and a machine stand 5 on a traveling device 4 is installed. The output shaft 6 of the prime mover 3 and the input shaft 7 that interlocks the threshing device 2, the reaping device 1, or the traveling device 4 are disposed near the front outer side of the threshing device 2,
A belt 8 is interlocked between the output shaft 6 and the input shaft 7 to constitute a power transmission device for a combine harvester.

This invention has the following technical effects due to such a configuration. That is, for example, when the belt 8 that drives the input shaft 7 linked to the threshing device 2 and the reaping device 1 from the output shaft 6 of the prime mover 3 located at the side end of the machine stand 5 needs to be replaced, the reaping device 1 There is no need to remove the belt 8 from the aircraft, and since such a belt 8 is usually equipped with a tensioning device for the belt 8, it is only necessary to loosen the belt 8 using the screws of this device and then remove it. Also, when attaching the belt 8, the order may be reversed. Note that if there is another belt outside this belt 8 that is linked to the sorting section of the threshing device 2, this belt may be removed first as described above.

In the illustrated example, a running transmission device 9 interlocked with the traveling device 4 below the machine base 5 is located approximately at the center of the front end of the machine base 5, and a support shaft portion 10 provided at the top of the transmission device 9 A reaping device 1 supported by and movable in the vertical direction and for reaping and transporting grain culms to the rear is provided at the front of the machine 5. To one side of
The support shaft 10 is extended to the upper part, and at the rear of this transfer section, a threshing device 2 is installed on the machine base 5 along one side edge of the machine base 5 to thresh the grain while transporting the grain culm rearward. to be placed. A prime mover 3 is mounted on the other side machine stand 5 at the front of this thresher 2, with the cooling fan 12 facing outward and the output shaft 6 facing inward. is the pilot's cockpit 1
3 is provided, and a control platform 14 is provided extending downward from the front part thereof and protruding from the front end of the machine platform 5, on which each control rod and the like are disposed. Note that the output shaft 6 of the prime mover 3 is connected to the threshing device 2 by providing a shaft coupling 15 etc. in the intermediate part.
The bearing 16 extends to the side end of the machine stand 5 on the side, and together with the upper input shaft 7 along the output shaft 6.
The other inner end of the input shaft 7 is supported by a bearing 17 provided on the front surface of the threshing device 2. The running drive pulley 18 that is rotatably mounted inside the bearing 16 interlocks a belt 21 with a running input pulley 20 at the end of the running input shaft that is supported on a bearing portion 19 that protrudes from the upper part of the running transmission device 9 in the direction of the bearing 16. Also bearing 16
A drive pulley 22 is also mounted on the outside, and the bearing 16
The belt 8 is interlocked with the input pulley 23 for the input shaft 7 on the outside of the upper bearing part which is integrated with the input shaft 7. A pulley 24 is rotatably attached to the input shaft 7 end outside the inner bearing 17, and a belt 27 is interlocked with a handling barrel shaft input pulley 26 provided on a handling barrel bearing portion 25 on the front surface of the threshing device 2. In addition, a pulley 28 that is rotatably mounted on the input shaft 7 and inside the bearing 16 connects the belt 30 to the reaping input pulley 29 provided at the outer end of the support shaft 10 of the reaping device 1.
The input pulley 2 on the input shaft 7
3. A pulley 31 is also attached to the outer input shaft 7 end,
Belts 29 are interlocked with pulleys provided at the sorting section, grain transfer section, etc. of the rear threshing device 2, respectively.

The reaping device 1 has an arrangement in which the upper end of the interlocking frame 32 is supported on the upper end of the traveling transmission device 9 case by a support shaft 10 so as to be vertically movable, and can be raised and lowered with respect to the traveling device 4 by a hydraulic cylinder 34. 33 is the machine frame 32
The cutting blade at the lower end, 35 is a grain culm lifting device provided in the vertical direction in front of this cutting blade, and 36 is a grain culm collecting mechanism provided from the upper front part to the rear part of the cutting blade device 33, and 35 is a grain culm lifting device provided in the vertical direction in front of this cutting blade. It is configured to collect and transport them to the rear transport device 11. This transfer device 11 is made of an endless body or the like, and its front end is positioned behind the pulling device 35 and its rear end is connected to the grain culm transfer device 37 of the threshing device 2 so as to transfer the stock base and ear tip of the harvested grain culm respectively. It is located at the front end of the grain culm to be transferred to the transfer device 37 and supplied to the threshing device 2.

By driving the prime mover, the rotation is interlocked with the running input pulley 20 via the output shaft 6, the running drive pulley 16, the belt 21, etc., and the running device 4 is interlocked and driven via the running transmission device 9, and the output shaft 6 end The drive pulley 22 drives the input shaft 7 by an input pulley 23 via the belt 8. The pulley 24 at the inner shaft end of the input shaft 7 drives the handling cylinder shaft input pulley 26 via the belt 27, and the handling cylinder bearing part 25 changes the transmission direction backward to drive the handling cylinder shaft. Further, from the input pulley 23 of the input shaft 7 and the pulley 31 at the end of the outer shaft 7, a rearwardly directed belt 32 drives each pulley that is interlocked with the sorting section, grain transfer section, etc. in the threshing device 2. Further, the pulley 28 on the inside of the input shaft 7 bearing 16 drives the input pulley 29 of the reaping device 1 in front of it via the belt 30.
Each mechanism 33, 35, 36, such as the reaping part and the transfer part,
Power is linked to 11.

With this illustrated configuration, in addition to the above effects,
The effect of hot air from the prime mover 3 cooling fan 12 is as follows:
Because each belt 8, 21 is located on the outside of the machine base 5 away from the prime mover 3, it is less susceptible to
Further, a space near the output shaft 6 extending from the prime mover 3 to the outer belt 21 can be used for installing a fuel tank for the prime mover 3, for example.
