Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvesting section of a combine harvester.

0002

[Prior Art] Conventionally, in combine harvesters, the lower end of a vertical transmission frame is connected and fixed to a horizontal transmission case, and a hoisting device, raking device, cutting blade device, etc. are attached to this. The reaping section is integrally attached to the vehicle body, and the reaping section is attached to the vehicle body by attaching the upper end of the vertical transmission frame to the vehicle body. The reaping section is driven by inputting driving force from the vehicle body to the transmission device in the transmission case via the transmission shaft in the transmission frame.

However, since the reaping section of a combine harvester has a complicated structure, when reaping work is carried out, the pulling device, raking device,
It is easy for mowing blade devices and the like to become entangled with straw and weeds, clogged with mud, etc., and it is necessary to perform maintenance on each of the above-mentioned parts in a timely manner. To make this maintenance easier,
Conventionally, structures designed to facilitate maintenance have been devised. For example, the longitudinal transmission frame mentioned above
By rotating the body-mounted part at the upper end of the arm outwardly with respect to the vehicle body, the entire reaping section is rotated outwardly of the vehicle body, and the back surface of the reaping section is exposed, allowing maintenance to be performed from the back surface. There are some things that can be done easily.

0004

[Problems to be Solved by the Invention] In the above-mentioned conventional reaping section of a combine harvester, the attachment part to the vehicle body at the upper end of the transmission frame is also the center of vertical movement when adjusting the cutting height of the reaping section. It is also a drive input section. Therefore, the configuration for laterally rotating the mounting portion inevitably becomes complicated.

[0005] Furthermore, in the conventional configuration, the transmission case in the lateral direction
Because the base and transmission frame are always connected and fixed,
Even if an attempt was made to perform maintenance from the rear side of the reaping section by rotating the reaping section outward, the transmission frame would get in the way, causing trouble in the work.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention takes the following technical means. That is, a pulling device 2, a raking device 3, a cutting blade device 4, etc. are integrally provided to a transverse transmission case 1 to constitute a reaping device 5, and the transmission case 1 is The reaping device 5 is configured to be detachable from the lower end of the transmission frame 7 attached to the vehicle body 6 of the combine. The reaping section of the combine is characterized by being provided with a reaping device opening means 8 that allows the reaping device to be moved laterally or vertically.

[0007]

The reaping section of the combine harvester according to the present invention has a configuration in which a transverse transmission case 1 is detachably attached to the lower end of a transmission frame 7 mounted on a vehicle body 6. Moreover, since the transmission frame 7 only needs to be mounted to the vehicle body 6 so as to be able to move vertically and vertically, this mounting structure can be simplified. When maintenance of the reaping section is required, the operator opens the transmission case 1 based on the reaping device release means 8.
is removed from the lower end of the transmission frame 7. Then, the transmission frame 7 is left on the vehicle body 6 side, and the transmission case 1 is moved, thereby moving the reaping device 5 laterally or vertically. As a result, the back surface and some side surfaces of the reaping device 5 are opened to the outside, and maintenance can be easily performed. Thereby, the efficiency of maintenance work for the reaping device 5 can be improved.

[0008]

[Embodiment] The structure of a reaping section of a combine harvester in an embodiment of the present invention will be explained. The combine harvester body 6 is
A threshing device 10, a grain storage device 11, a control section 12, etc. are provided above the endless track belt traveling device 9. The reaping device 5 includes a frame extending forward from the transverse transmission case 1.
A grass divider 14 is attached to the tip of the frame pipe 13, and a lug-type pulling device 2,
It is constructed by attaching a raking device 3 consisting of a lag belt and star foil, a clipper type cutting blade device 4, and the like. The pulling device 2 is supported and driven by a transmission pipe 15 extending upward from the transmission case 1.

On the other hand, in the vicinity of the lower end of the cylindrical transmission frame 7, which is attached to and supported by the vehicle body 6 so as to be movable up and down by a hydraulic cylinder 16, there is a horizontal pipe frame 17.
to fix. Incidentally, near the upper end of the transmission frame 7, a supply conveyance device 18 is attached. Then, the transmission case 1
The outer end of the pipe frame 17 is pivotally attached to the outer end of the pipe frame 17 with a longitudinal axis 19. As a result, the transmission case 1 is configured to be rotatable in the lateral direction. That is, the reaping device 5 is configured to be rotatable toward the outside of the machine body. Also,
A fixing device 20 is provided on the other end side of the transmission case 1, and the fixing device 20 fixes this state in which the pipe frame 17 and the transmission case 1 are parallel to each other. Configure to retain. The structure of the transmission case 1, pipe frame 17, shaft center 19, and fixing device 20 described above constitutes the reaping device opening means 8.

Further, an opening 21 is provided in the middle part of the transmission case 1, and the opening 21 is opened when the reaping device is closed (fixed).
The lower end of the transmission frame 7 is connected to the transmission frame 1. Furthermore, a drive shaft 23 having a bevel gear 22 is rotatably installed inside the transmission case 1. The central bevel gear 22 is connected to a transmission shaft 24 installed inside the transmission frame 7.
It meshes with a bevel gear 25 provided at the lower end.

With the above configuration, when the reaping device 5 requires maintenance, the operator first moves the fixing device 20 to the reaping device 5.
is released, and the transmission case 1 is rotated outward about the axis 19. At this time, the opening 21 of the transmission case 1 and the lower end of the transmission frame 7 are separated. The reaping device 5 that has been rotated outward has its back surface and side surface facing toward the inside of the machine body completely opened, allowing easy maintenance.
