Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stock feeding device in a straw binding machine of a mobile agricultural machine.

[Conventional technology]

Generally, a straw binding machine equipped in a mobile agricultural machine such as a combine binds the straw fed from the straw transport chain as it is with a root aligning plate to align the stocks. For this reason,
In order to bind at the desired bundling position, the position of the straw bundling machine has to be changed every time the culm length of the straw is different, and the root aligning plate also becomes an appropriate root aligning position accordingly. Had to adjust to.

Therefore, even if the culm length is different, so that the stock origin position is constant,
It is proposed that a rotation belt for pulling stock is provided from the rear part of the straw conveying chain toward the straw binding machine (for example, Japanese Patent Laid-Open No. 62-151112).

[Problems to be solved by the device]

However, even if it is possible to push the root of the straw stock toward the tip of the straw by simply providing the stock pulling rotation belt toward the straw binding machine, since the backward conveying force is weak, the stock is not conveyed. When the amount of straw is large or the posture of the straw is disturbed, the straw is often clogged in front of the straw bundling machine, which causes a problem in work. Moreover, even after striking the roots with the root aligning plate after being sent to the straw binding machine, the roots could not be effectively aligned and bound.

The present invention was devised in view of the above-mentioned circumstances, and reliably conveys straw from the straw-conveying chain toward the straw-binding machine, and while moving it toward the tip side of the stem direction in the conveying process. Since the roots can be aligned, the roots are effectively aligned with the rooting plate, and the roots feeding device in the straw bundling machine of a mobile agricultural machine that can always tidy up in an appropriate straw posture is provided. This is the purpose of the task.

[Means for solving the problem]

In order to solve the above-mentioned problems, the technical means taken by the present invention is a straw bundling machine in which straw fed from a straw transport chain is bound while being aligned by a root aligning plate. At the end of the stock, between the stock binding side and the straw bundling machine, the stock feeding chain is arranged in an inclined shape toward the tip side,
The stock source transport chain is provided with a plurality of transport claws protruding in the direction of the straw of the straw at predetermined intervals, and a fixed plate is provided on the base end side of the transport claws along the transport trajectory of the transport claws. It is characterized in that the straw is transported while the stocker is in sliding contact with the fixed plate.

[Function of device]

Therefore, according to the present invention, the straw fed by the straw transport chain is carried over from the terminal end of the straw transport chain to the stock carrier transport chain, and is transported to the straw binding machine by the transport claws of the stock transport chain. To be done. At this time, the root of the straw is transported along the transportation trajectory while being slidably supported by the inclined fixed plate provided on the transportation trajectory of the transportation claw and pressed toward the tip side, so that it is discharged during the transportation process. Straws can be brought closer to the tips of the shoots in the direction of culm, and the fixed plate can be used to align the stocks.
Therefore, it is possible to further bind the straw discharged to the straw binding machine in a state where the stocks are aligned in advance by aligning it with the root aligning plate, so that the straw can be bound in an appropriate posture.
