Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives a mowing grain culm conveyed by a vertical conveying device of a mowing section from the vertical conveying device, and inserts its tip side into a handling chamber from an input port of the threshing device. The present invention also relates to a self-removing combine equipped with a feed chain, which is held and conveyed so as to pass through the handling chamber, on the lateral side of the threshing device.

[0002]

2. Description of the Related Art Conventionally, in such a self-removing combine as described above, the feed chain is composed of a single one that is wound so as to extend from the terminal end of the vertical conveying device to the rear end of the threshing device. It was

[0003]

By the way, in the self-removing combine, if there is a planted culm that cannot be cut by the combine, the operator cuts the planted culm by hand and feeds it. Manually supply to the beginning of the chain,
A so-called pillow threshing operation is performed in which the feed chain puts the threshing device into the handling chamber through the throwing port and the threshing device threshes. However, in the above-mentioned conventional technique, the mowing part is arranged immediately before the feed chain, and the feed chain is wound so as to extend from the end part of the vertical conveying device to the rear end part of the threshing device. It is composed of a single unit, and even during pillow threshing work, it will be driven to rotate from the end part of the vertical transfer device to the rear end part of the threshing device, so the cut culms will be manually supplied during the pillow threshing work. Just before the starting end of the feed chain, it is impossible to provide a placing space for temporarily placing the harvested culms. That is, at the time of pillow threshing work in the above-mentioned conventional technique, the mowing culm must be temporarily placed at a location away from the starting end of the feed chain, and therefore the worker must mow at a location away from the starting end of the feed chain. Once the grain culms have been temporarily placed, the proper amount of harvested grain culms that can be put into the handling room is picked up once from each location, conveyed to the beginning of the feed chain and manually fed. Since it has to be repeated, there is room for improvement in improving the work efficiency during the pillow threshing work.

An object of the present invention is to enable temporary placement of the harvested grain culm just before the start end of the feed chain for feeding the harvested grain culm into the handling chamber from the input port of the threshing device during the pillow threshing work. It is to improve work efficiency during work.

[0005]

In order to achieve the above object, in the invention according to claim 1 of the present invention, the feed chain mounted on the lateral side of the threshing device is conveyed by the vertical conveying device of the mowing section. From the front feed chain portion, a front feed chain portion that receives the harvested culm culm that is received from the vertical transport device and conveys it by sandwiching to the input port of the threshing device, and the harvested culm transported by the front feed chain portion. Receiving, the tip side is formed into two parts into a rear feed chain part that is inserted into the handling chamber from the input port of the threshing device and is sandwiched and conveyed so as to pass through the handling chamber, and the front feed chain part The drive can be stopped independently of the rear feed chain portion.

According to the first aspect of the present invention, during a normal mowing operation, the front feed chain portion is driven by the front feed chain portion and the rear feed chain portion, so that the front feed chain portion is conveyed by the vertical conveying device of the cutting portion. The harvested culm culms are received from the vertical transport device and held and transported to the input port of the threshing device, and the rear feed chain part receives the slaughtered culm transported by the front feed chain part from the front feed chain part and the tip side The threshing device is thrown into the handling chamber through the feeding port and is conveyed while being held so as to pass through the handling chamber. On the other hand, at the time of pillow threshing work, the drive of the front feed chain part is stopped and only the rear feed chain part is driven, and then the hand cut corn culm is manually fed to the starting end part of the rear feed chain part. The feed chain part holds the manually supplied cut culm so that the tip side of the cut culm is inserted into the handling chamber from the input port of the threshing device and passes through the handling chamber. At this time, since the drive of the front feed chain portion arranged immediately before the starting end portion of the rear feed chain portion is stopped, the front feed chain portion is used as a placing table for temporarily placing the harvested culm. You will be able to.

That is, during the threshing work of the pillow, the harvested grain culm can be temporarily placed on the front feed chain portion arranged immediately before the starting end of the rear feed chain portion, and the worker can feed the harvested grain culm to the front feed portion. Once temporarily placed on the chain part, a proper amount of harvested culm that can be put into the handling room is grabbed from there, and it is arranged just after that, and it is manually fed to the starting end of the feed chain part. Since it is only necessary to repeat the above-mentioned operation, it is no longer necessary to temporarily place the harvested culm at a location away from the start end of the feed chain, and an appropriate amount of harvested grain that can be put into the handling room from that location is removed. There is no need to repeatedly perform a troublesome series of operations, such as grasping the culms one by one, conveying them to the starting end of the feed chain, and manually supplying them.

Therefore, it has become possible to improve the work efficiency during the pillow threshing work.

According to the second aspect of the present invention,
In addition to the invention described in claim 1, the front feed chain portion is driven by power transmitted through a mowing clutch that switches a transmission state to the mowing section, and the rear feed chain portion is It is configured to be driven by the power transmitted through the threshing clutch that switches the transmission state to the threshing device.

According to the second aspect of the present invention, when the cutting unit is driven by operating the cutting clutch, the front feed chain portion can be driven in conjunction with it.
When the driving of the mowing section is stopped by operating the mowing clutch, the driving of the front feed chain portion can be stopped in conjunction with this. Further, when the threshing device is driven by the operation of the threshing clutch, the rear feed chain portion can be driven in conjunction with it, and when the driving of the threshing device is stopped by the operation of the threshing clutch,
In conjunction with this, the drive of the rear feed chain portion can be stopped. In other words, during normal mowing work that drives both the mowing unit and the threshing device, the front feed chain part and the rear feed chain part are automatically driven, and the driving of the mowing unit is stopped and only the threshing device is driven. During the pillow threshing operation, the driving of the front feed chain portion is automatically stopped and only the rear feed chain portion is driven.

Therefore, it has become possible to improve the operability when switching the combine work posture from the mowing work posture to the pillow threshing work posture and from the pillow threshing work posture to the mowing work posture.
