Description

[Detailed description of the invention] The present invention provides a straw removal chain at the rear of the threshing device that is inclined toward the rear side of the machine and toward the tip of the grain, and a pinning rail for the removal straw chain in order to dispose of different types of waste straw. The divided rail portion on the transport end side is provided so as to be freely displaceable in the longitudinal direction of the machine that intersects with the longitudinal direction of the straw removal chain, so that the waste straw can be separated into a first falling path in the middle of the straw removal chain and a second falling path at the end of the straw removal chain. A threshing machine configured to selectively supply grains, and having a lid that opens and closes the first and second falling paths in a manner that is slidable in a longitudinal direction of the machine that intersects with the longitudinal direction of the straw removal chain. This invention relates to the structure of the waste straw processing section.

In the above-mentioned method, when changing the straw disposal form, not only can the split rail portion be displaced, but also the cover body can be opened and closed contrary to the first and second falling paths to prevent unnecessary dropping. The route is open to prevent the waste straw from accidentally getting caught in the process of being conveyed, or from accidentally inserting your hand into the waste straw chain and causing injury.
The opening/closing of the lid body and the displacement of the split rail portion are both linked to each other so that they can be performed at the same time. The body and the split rail part can be linked together via wires, or
In addition to a link mechanism, a mechanism for pushing down the split rail portion near the chain is attached to avoid interference with the locking pawl of the chain, making the interlocking structure complicated.

In view of the above points, the present invention aims to simplify the interlocking structure between the lid body and the split rail part while suppressing interference with the chain through rational improvements. .

Next, embodiments of the present invention will be described in detail with reference to the drawings.

At the rear of the threshing device 1, a shredding device 2 and a dropper 3 are provided in a state in which they are lined up in that order, and
The structure is such that the waste straw from the feed chain 4 is selectively supplied to the shredding device 2 and the dropper 3 via the waste straw chain 5 by displacing the divided rail portion 6a on the conveyance end side of the nipping rail 6. However, the waste straw processing section of the combine is configured so that the threshed waste straw can be shredded and released into the field as necessary, or it can be intermittently released in predetermined amounts in the form of long straw.

First and second falling paths 7 and 8 are provided above the shredding device 2 and the dropper 3 for dropping and supplying waste straw from the waste straw chain 5, and a plate-shaped lid 9 is slidable in the longitudinal direction of the machine. The first and second falling paths 7 and 8 are configured to be freely movable and can be opened and closed in a contradictory manner, and when supplying waste straw to the shredding device 2,
The second fall path 8 is closed, and in cooperation with the cover part 1a extending from the threshing device 1, it is possible to avoid accidentally inserting your hand and getting injured by the chain 5.
On the other hand, when supplying to the dropper 3, the first falling path 7 is closed, and the transported waste straw may get caught in the first falling path 7, or the waste straw that has slipped through may be unexpectedly supplied to the shredding device 2. It is configured so that nothing happens.

The waste straw chain 5 is provided at an inclination so that the waste straw can be conveyed to the side away from the feed chain 4, and among the opposing chain plates 10a and 10b that constitute it, the waste straw is provided on the stock side. The actuating part 10a is not provided with a locking pawl, and only the actuating part 10b on the tip side is provided with a locking pawl 11, and the divided rail portion 6a
is attached to the lid 9 so as to be able to slide integrally therewith, and the split rail portion 6a can be displaced from the working position to the non-working position as the lid 9 slides without interfering with the chain plate 10a. It is structured as follows.

In the figure, reference numeral 12 denotes a magnet for maintaining the lid 9 in a state where the second fall path 8 is closed.

In the waste straw chain 5, the rear end of the rotation trajectory of the stock side chain plate 10a and the rear end of the tip rotation trajectory of the locking pawl 11 of the ear side chain plate 10b are substantially parallel to the culm direction of the transported waste straw. It is inclined at a predetermined angle (approximately 50 degrees, for example) with respect to the feed chain 4 so that the waste straw caught in the chain 5 is prevented from being caught upward. It is structured as follows.

Incidentally, in the present invention, the divided rail portion 6a
It is sufficient that the other side chain plate 10b can be freely displaced from the working position to the non-working position without being blocked by the chain plate 10a.
A locking claw with a smaller protrusion than the locking claw 11 may be provided.

In addition, in order to dispose of the waste straw from the first falling path 7, a binding device may be provided in place of the shredding device 2, or on the other hand, to dispose of the waste straw from the second falling path 8, it may be discharged. In short, any method that performs different types of straw removal treatment is sufficient, and various modifications are possible.

The present invention is applicable not only to combines but also to various threshing machines such as harvesters.

In summary, the present invention provides the above-mentioned structure of the waste straw processing section of the threshing machine, in which the split rail portion 6
a is integrally and slidably attached to the lid body 9, and in the chain 5, the locking claw that acts on the stock side of the conveying and discharging straw is eliminated, or the locking claw 11 that acts on the tip side of the straw is protruded by an amount It is characterized by being small in size and configured to allow the position of the divided rail portion 6a to be changed at will.

In other words, by rationally improving the locking pawl on the stock side of the chain 5, the split rail portion 6a can be attached to the lid 9 without making it come into contact with the locking pawl, or Even if they come into contact with each other, the chain 5 can be passed through with little resistance, and the chain 5 due to the displacement of the split rail portion 6a
Interference between the lid body 9 and the split rail portion 6a can be suppressed, and the interlocking structure of the lid body 9 and the divided rail portion 6a can be simplified as a whole.
