Description

[Detailed description of the invention] This invention relates to a combine harvester in which an engine is arranged on the side of a vertical transport device for harvested stalks from the harvesting section to the threshing section located behind it, with an output shaft for transmitting and distributing power to each section positioned on the side of the vertical transport device.

In this type of combine harvester, the engine and the transmission mechanism from there to each part are densely arranged in a narrow space surrounded on three sides by the vertical conveyance device of the reaping section and the threshing section, so maintenance of the engine and transmission mechanism is extremely difficult. It is difficult to Conventionally, therefore, it has been common practice to take the engine out of the machine to expose not only the engine itself but also the transmission mechanism to the outside, thereby facilitating maintenance.

However, in conventional combine harvesters, when configuring the engine so that it can be taken in and out of the machine, the engine output shaft and the driven part were linked and connected by a key or the like. In addition, if the interlocking part between the engine and the driven part such as a transmission mechanism is manually released, and even after the engine is installed, if the interlocking part between the engine and the driven part is manually connected, Furthermore, both of these operations had to be carried out in a narrow space, so although the engine could be removed, the overall maintenance work required an extremely large amount of effort and time.

The technical problem to be solved by the present invention is to solve the problem by simply moving the engine together with the output shaft in the direction of the axis of the output shaft for transmission distribution.
The purpose is to allow the engine to be taken in and out of the machine quickly and easily.

The technical measures taken to solve the above technical problem are such that the power distribution winding wheel body, which is attached to the power distribution output shaft in a rotationally interlocked state, can only be rotated by a stay connected to the machine side. An interlocking connection part is provided which holds the wheel body in a fixed position and allows the wheel body and the power transmission distribution output shaft to interlock and disengage freely in the axial direction of the power transmission distribution output shaft.

The above technical means works as follows.

A winding wheel for power distribution, which is rotationally interlocked with the output shaft for power distribution, is held in a fixed position so as to be able to rotate only, on a stay connected to the machine side, and this wheel and the output shaft are connected to each other. Since the interlocking can be interlocked and disengaged freely in the axial direction, by moving the engine integrally with the output shaft in the axial direction, the winding wheel can be fixedly held on the machine side and the wheel can be removed. The output shaft can be linked and released.

Therefore, the present invention has the following effects.

That is, by simply moving the engine in the axial direction of the output shaft, the engine can be quickly and easily taken in and out of the machine together with the output shaft. This makes it possible to remove the engine from the machine and perform maintenance work on the engine and driven parts efficiently in a sufficiently large work space.
The troublesome work associated with attaching and detaching the engine and driven parts is no longer necessary, and the entire maintenance work can be completed in a short period of time with extremely fewer man-hours.

Hereinafter, an embodiment of the present invention will be described based on the drawings. As shown in FIGS.
At the lower part of the operator's seat 8 located on the lateral side of the vertical conveyor 3 of the harvested grain culm and between the grain bagging device 2A of the reaping section 1 and the threshing section 2, there is an output consisting of its crankshaft. The engine 5 is disposed with the shaft 4 located on the vertical conveyance device 3 side, and the input shaft 11 attached to the mission case 10 and the threshing section 2 are connected to the crawler traveling device 9 from the output shaft 4.
belt transmission devices 16, 17, 1 to the input shaft 12 of the hydraulic pump 14 and the input shaft 15 of the hydraulic pump 14 for the hydraulic cylinder 13 for driving up and down the reaping section 1, respectively.
In the combine harvester, which is configured to distribute and transmit power via the engine 8, the plate-shaped frame 19 on which the engine 5 is mounted is attached to a pair of front and rear frame members 20, 20, as shown in FIGS. 4 and 5. The machine frame members 20, 20 pairs are slidably mounted as guides to configure the engine 5 to be freely inserted into and removed from the machine in the axial direction of the output shaft 4. The belt transmission device 1
An interlocking connection portion 6 is provided between the groups 6, 17, and 18, and is detachable in the engine removal direction and interlocked in the engine installation direction.

As clearly shown in FIG. 4, the interlocking connecting portion 6 is attached to the output shaft 4 in a rotationally interlocking manner, and is formed with belt wrapping portions 21, 22, 23 for each belt transmission device 16, 17, 18. Ta1
The two power transmission distribution winding wheels 7 are fixedly held in position by a stay 24 connected to the machine side so that they can only rotate.
Moreover, a spline is provided between the wheel body 7 and the output shaft 4 to interlock the two 7 and 4 when the engine 5 is installed, and to release the interlock when the engine 5 is removed. be.

Incidentally, a support leg 25 is attached to the distal end of the engine mounting plate frame 19 in the removal direction, which can be switched between a ground support posture and a storage posture along the plate frame 19 by swinging around the front and rear axis. It has been done.

Further, the belt transmission devices 16 and 17 to the traveling device 9 and the threshing device 2 are configured to serve as a belt tension clutch.

Further, the output shaft 4 may be a counter shaft protruding from a counter case attached to the engine 5.
