Description

[Detailed Description of the Invention] The present invention relates to a power transmission device for a combine harvester in which a threshing device and a prime mover are arranged on the left and right sides.

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 upper side of the front side of the threshing device is covered with the transfer device. It is narrow and has a complicated structure. Therefore, each of these threshing devices is equipped with a prime mover in the front part of the threshing device on the side of the tip of the grain culm to be transferred.
When transmitting power to reaping equipment, traveling equipment, etc.
If the interlocking mechanisms for these various parts are concentrated on the tip side, that is, on the prime mover side, disassembling, assembling, repairing, etc. of each of these transmission mechanisms requires time and effort, and is likely to be dangerous.

In contrast, in the present invention, a threshing device 2 is provided with a feed chain 2a that inherits the grain culm harvested by the front reaping device 1 and threshes the grain while transferring it to the rear.
is mounted on a machine base 5 equipped with a traveling device 4, with a prime mover 3 located on one side and a prime mover 3 on the other side. At least an input shaft 7 interlocked with the threshing device 2 is disposed horizontally and vertically in parallel, and the output shaft 6 and the input shaft 7 are connected to the belt on one side opposite to the prime mover side. 8. By connecting the output shaft 6 of the prime mover continuously so as to transmit power, the input shaft 7 to at least the threshing device 2 etc.
The belt 8 transmission mechanism that drives the belt 8 can be repaired, inspected, maintained, etc. very easily in a large space on one side opposite to the prime mover, without removing the reaping device, etc., which improves maintenance. However, in addition to this, in the present invention, the input shaft 7 and the transmission shaft 10 to the handling cylinder 9 of the thresher 2 are connected to the belt 11 on the other side closer to the prime mover 3. By configuring it so as to obtain, the balance of power transmission distribution is maintained, and

2 is connected and held to the support member 14 of the input shaft 7 via the reinforcing member 13, so the support member of the input shaft 7 can be effectively used as a strength member, and no special support member is required. It has now become possible to increase the strength of the frame structure of the handling room.

In the illustrated example, the traveling transmission case 15 linked to the traveling device 4 below the machine base 5 is connected to the machine base 5.
This case 15 is located approximately at the center of the front end of the
A reaping device 1 is installed in the front part of the machine 5, and is supported by a support shaft provided on the upper part of the machine and is movable in the vertical direction.
The transfer device 16 extends upward at the rear to near the supply port of the threshing device, and at the rear of this transfer device, a device is provided along one side edge of the machine base 5 while transferring the grain culm to the rear. The threshing device 2 for threshing is mounted on the machine 5.
placed above. This threshing device 2 front other side machine stand 5
A prime mover 3 is mounted on the top, and the output shaft 6 of this prime mover 3 is provided with a shaft coupling 6a etc. in the middle and extends to the end on the side of the machine base 5 on the threshing device 2 side, and along the output shaft 6. The bearing 1 at the end of the machine base 5 along with the input shaft 7 at the top of the
The other inner end of the input shaft 7 is supported by a support member 14 which is supported via a bracket 14a provided on the front surface of the threshing device 2. The travel drive pulley 18 that is pivoted inside the bearing 17 is attached to the bearing portion 1 that protrudes from the upper part of the travel transmission case 15.
Travel input pulley 2 at the end of the travel input shaft supported by shaft 9
A belt 21 is interlocked with the belt 21, and a drive pulley 22 is also attached to the outside of the bearing 17, and the belt 8 is passed around the input pulley 23 for the input shaft 7 outside the upper bearing part integral with the bearing 17, and the tension pulley 8a It is configured so that it can be linked via . A pulley 24 is rotatably attached to the input shaft 7 at the end of the input shaft 7 outside the inner bearing 14.
The belt 11 is wrapped around a pulley 26 of a transmission shaft 10 provided in a transmission box 12 that houses a transmission mechanism to a handling cylinder 9 on the front side of the threshing device 2, and is configured to be interlocked via a tension pulley 25. A pulley 31 is also pivotally attached to the end of the input shaft 7 outside the input pulley 23 on the input shaft 7, and the belt 32 is interlocked with the pulleys provided in the sorting section, grain transfer section, etc. of the rear threshing device 2. Ru. Further, a pulley 28 which is attached to a shaft taken out from the transmission in the traveling transmission case 15 is interlocked with a reaping input pulley 29 to the reaping device 1 by a belt 30.

By driving the prime mover, the rotation is linked to the running input pulley 20 via the output shaft 6, the running drive pulley 18, the belt 21, etc., and the running device 4 is interlocked and driven via the running transmission, and the drive of the end of the output shaft 6 is Pulley 22 drives input shaft 7 via input pulley 23 via belt 8 . The pulley 24 at the inner shaft end of the input shaft 7 connects the pulley 26 via the belt 11.
And the transmission shaft 10 is driven, and the handling cylinder 9 is rotationally driven. 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. Furthermore, the pulley 28 pivotally supported by the transmission case 15 drives the input pulley 29 of the reaping device 1 in front of it via a belt 30, thereby transmitting power to each part of the reaping device 1.
