Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a transmission case extending from a traveling machine body so that the mounting position in the lateral direction of the machine body can be freely changed to connect the reaping unit and the traveling machine body. The present invention relates to a combine transmission structure in which a rotating shaft in a machine body front-rear direction that is transmitted from the to the reaping section to the harvesting section is installed in the transmission case.

[Conventional technology]

The above combine is used to keep the traveling machine away from the uncut side grain rods as much as possible in order to prevent the soil pushed out by the crawler traveling device during the mowing work from covering the uncut grain rods. In order to prevent the uncut mowing rods on both sides of the machine from being pushed down by the machine at times, the position of the raising and cutting section should be adjusted to minimize the lateral protrusion from the cutting and cutting section. It is configured to be changeable.

Conventionally, as shown in FIG. 8, a drive case (22) is installed in a drive case (22) of the raising and mowing section, and a drive case (1

(E) is slidably mounted, and a long hole (22A) is formed in the drive case (22) to allow the drive case (22) to move laterally of the machine with respect to the transmission case (14). The position of the raising and mowing section was changeable.

[Problems to be solved by the invention]

According to the above-mentioned conventional structure, the sliding space of the transmission section (E) accompanying the lateral movement of the drive case (22) is provided in the drive case.
It must be secured inside the (22), and also a long hole that allows the drive case (22) to move with respect to the transmission case (14).
(22A) It is necessary to increase the thickness of the drive case (22) so that the strength of the drive case (22) does not decrease, and there is a disadvantage that the drive case (20) becomes large. It was

An object of the present invention is to enable downsizing of a drive case.

[Means for solving problems]

According to a characteristic structure of the present invention, in the structure of the transmitting portion of the combine described above, the intermediate transmission shaft that is transmitted from the rotating shaft to the drive rotating shaft in the lateral direction of the machine, which is installed in the drive case of the raising and mowing unit, It is arranged in parallel with the drive rotating shaft and slidably attached to the outside of the drive case integrally slidably through the transmission case. Its action and effect are as follows. Is the street.

[Action]

Even if the intermediate transmission shaft is attached to the outside of the drive case, power can be transmitted from the transmission case to the drive case by the action of the intermediate transmission shaft, and the attachment of the intermediate transmission shaft to the drive case and the transmission case are performed. The drive case can be laterally movably connected to the transmission case by the penetration.

[Effect of device]

Therefore, the structure for transmitting the drive case to the drive case while allowing the lateral movement of the drive case by the action of the intermediate transmission shaft is arranged outside the drive case, and the drive case is provided in the space inside the transmission mechanism. From the aspect of the transmission structure, it is possible to make it smaller than the conventional one in terms of both surface and wall thickness, and to raise and change the position of the mowing part according to the work form such as splitting work and turning work. I got it.

Explaining the transmission structure of the pre-reaping processing unit (A),
As shown in FIG. 3, there is provided a first transmission case (8) in which a first transmission shaft (7) in the lateral direction of the vehicle body to which power from an engine (not shown) is input is provided, and the first transmission shaft (8) is provided. The power transmitted to (7) is transferred to the transfer device via a bevel gear mechanism (9).
A second transmission case (11) containing a second transmission shaft (10) for transmitting to (D) is attached to the first transmission case (8). A third transmission case (14) containing a rotation shaft (13) in the longitudinal direction of the machine which is interlocked with the first transmission shaft (7) via a bevel gear mechanism (12) is installed around the horizontal axis (X). It is swingably attached to the first transmission case (8). The power transmitted to the rotating shaft (13) is an intermediate transmission shaft (15) in the lateral direction of the machine body, a gear mechanism.
Drive shaft (17) of the mowing device (6), drive shafts (18) and (18) of the merging and conveying device (C), and the raising devices (5) and (5) via (16). Inside the drive case (22) with the drive rotary shaft (21) transmitting to each of the drive shafts (20) interlockingly connected to the drive shaft (19) of the drive shaft (19) arranged in parallel with the intermediate drive shaft (15). I am doing it.

As shown in FIG. 1, the extension of the drive case (22) with the intermediate transmission shaft (15) slidably passing through the transmission portion (E) of the third transmission case (14).
