Description

[Detailed Description of the Invention] Industrial Field of Application [0001] The present invention relates to a combine of a removable reaping unit in which the reaping unit can be attached to and detached from the main body traveling unit. More specifically, in this type of combine, the present invention relates to a stock-source transport guide device including a feed chain of a main body traveling unit and a vertical transport device of a cutting unit.

○ Prior art As a conveyance guide structure of this type, a spring holder is attached to the end of a vertical conveying device on the cutting side, and a stock holding spring and a feed chain guide supported by the spring holder are elastically pressed against the leading end of the feed chain. Are applied in a biased state.

○ Problems to be solved by the present invention In the above-mentioned conventional technique, when the worker mounts the mowing part on the main body traveling part, the stock foot pressing spring and the feed chain guide are pressed against the elastic force so as not to collide with the feed chain. It is necessary to rotate it and maintain it at a position apart from the feed chain. Therefore, there is a problem that it is difficult to mount the mowing unit and the traveling unit by one person.

○ Means for solving the problems The present invention provides a stock holder and a spring holder for urging the feed chain guide toward the feed chain, and a first holder fixed to a connecting pipe of a cutting section, and a stock holder. The holder is divided into a second holder that supports the original presser spring and the feed chain guide, and the first holder and the second holder are provided at the connecting end portions of the side surfaces of both holders in the vertical direction. It is configured to be connectable with a locking member that can be fixed to each other in a state where the end faces are adjacent to each other.

○ Example FIG. 6 shows a general combine, and in front of the traveling part A including the threshing device a and the traveling device 22, the grass body 4, the raising device 5, the cutting device 6, the stock carrier device 7, the tip transfer The cutting unit (pretreatment unit) B including the device 8 and the vertical conveyance device 9 is attached to the chassis of the traveling unit A.
A support base 24, which is integral with 23, is vertically rotatable about a rotary pivot shaft 21 above the support base 24, and the detaching mechanism C allows the cutting section B to be detachable from the traveling section A. Is the same as. Further, referring to FIG. 7, the vertical conveying device 9 of the mowing section B and the feed chain 1 of the threshing device a of the main body traveling section A are referred to.
A spring holder 10 fixedly supported by the stock foot pressing spring 2, the feed chain guide 3 and the connecting pipe 25 of the reaping section B in order to guide the transfer of the stock of the cut grain culm between and (see FIG. 6). Then, it is the same as the conventional device that the conveyance guide device D including the tip end conveying device 8 is fixedly supported. Note that, in FIG. 7, reference numeral 26 is a vertical conveyance guide rod.

Hereinafter, with reference to FIGS. 1 to 5, a conveyance guide device D, which is a main part of the present invention, will be described.

The spring holder 10 for supporting the stock foot presser spring 2 and the feed chain guide 3 is fixed to the first position on the machine body.
It is divided into a holder 11 and a second holder 12 that supports the stock holding spring 2 and the feed chain guide 3, and the first holder 11 and the second holder 12 are provided on both outer sides of the machine to connect the two holders vertically. Direction supporting member P and a locking member Q for fixing the two holders to each other in a state where the end surfaces are adjacent to each other (the facing surfaces of the first holder 11 and the second holder 12 are adjacent to each other). The second holder 12 is configured to be pivotable outward with P as an axis and both holders 11 and 12 can be fixed.

In the first embodiment shown in FIGS. 1 and 2, the first
The pivot member P of the holder 11 and the second holder 12 is a hinge 13 which is positioned on the outer side and is attached in the vertical direction, and the locking member Q is pivotally supported by the base of the second holder 12 in the vertical direction. Lock bar 14, a first lock hole 15 for inserting the tip of the lock bar 14 into the first holder 11 at the transport position shown by the solid line in FIG. 1, and a non-transport position shown by the phantom line in FIG. The second lock hole 16 is provided for inserting the tip of the lock rod 14 at the (cutting-off position).

The cylinder 2a at the base end of the stock holding spring 2 is inserted into the support shaft 17 provided in the second holder 12 in the lateral direction, and the elastic force of the stock holding spring itself or an appropriate spring body (for example, the spring shown in FIG. 5) is used. 20 ') urges the working end 2b of the stock holding spring 2 toward the feed chain 1. Further, the base portion 3a of the feed chain guide 3 is laterally mounted on the second holder 12, and the spring body 18 is inserted, and both ends of the spring body 18 and the feed chain guide 3 are inserted at appropriate positions.
Then, the feed chain guide 3 is biased toward the feed chain 1.

In the second embodiment shown in FIGS. 3 and 4, the pivot member P is used as a pivot support 13 'to rotate the second holder 12 relative to the first holder 11 toward the side of the machine body. Freely moveable,
As shown in FIG. 4, the locking member Q has a pin 19B fixed to the second holder 12 and a pin 19B fixed to the first holder 11.
And a pin holder 19A that can be engaged with the first holder 11 and the second holder 12 at the carrying position (the connecting position of both holders) so that the first holder 11 and the second holder 12 can be fixed adjacent to each other at the end faces.

FIG. 5 shows an example of a mounting structure for the stock foot pressing spring 2, in which the base end 3a 'of the feed chain guide 3 is pivotally supported by the second holder 12 and the spring 20 is inserted in the base end 3a'. , The stock foot presser spring 2 is pivotally supported through the pin 17 ′ and the pin 17 ′.
The spring 20 'is inserted into the spring 20', and the springs 20 and 20 'urge the feed guide 3 and the stock holding spring 2 downward, so that the spring 20
20 ', feed guide base end 3a' and pin 17 '
Is installed in the second holder 12.

The conveyance guide device D of the present invention is normally fixed to the position shown by the solid line in FIG. 1 by the lock bar 14 and the first lock hole 15 so that the stock base pressing spring 2 and the feed chain guide 3 are brought into contact with the feed chain 1. ing.

When installing the mowing part B on the main body traveling part A, a lock rod
After raising 14 to release the engagement with the first lock hole 15, the second holder 12 is rotated outward to the non-acting position shown by the phantom line in FIG. 1, and the lock rod 14 is moved to the second lock hole. Lock with 16. In this state, the stock foot presser spring 2 and the feed chain guide 3 are directed to the side of the machine body and do not face the feed chain 1 of the main body traveling portion, so the feed chain 1
Away from the tip of. Therefore, the worker is
Also, it is not necessary to push up the feed chain 3 and the feed chain 1 in the fear of a collision between the feed chain 3 and the feed chain 1, and a single worker can perform the work of mounting the reaping section B on the main body traveling section.

○ Effect of the Invention In the present invention, the spring holder is divided into the second holder and the first holder, and the second holder can be rotated in the lateral direction. Therefore, the feed chain guide and the stock holding spring are contacted with the feed chain. Without having to do so, one operator can mount the reaping section on the main body traveling section.
