Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a combine straw discharging device, and more specifically, to a discharging straw including a conveyor chain and a sandwiching rail arranged below the conveyor at the rear of the threshing device. A combine straw discharge straw provided with a cutter for shredding the waste straw after threshing that is conveyed by a carrier device, and a long straw processing device for treating the waste straw in a long culm behind the cutter. Regarding a processing device.

[Conventional technology]

The waste straw processing after threshing by the combine described above is performed by selectively selecting the cutter and the long straw processing device, and while the cutter is used, the waste straw is shredded and returned to the field, When using a long straw processing device, for example, a binding machine, all the discharged straws are bound together.

If the shredded waste straw is returned to the field using a cutter, the soil will be fertilized, which is convenient. However, if all the waste straw is reduced as described above, the supply will be excessive and the soil quality will be deteriorated.

Therefore, as a countermeasure, for example, as shown in Japanese Utility Model Laid-Open No. 54-25475, by providing a supply path to the cutter in the middle of the discharge straw conveying device, both the cutter and the dropper behind the conveying device are provided. A technique is known in which discharge straws can be supplied at the same time so that the amount of shredded discharge straws per unit area can be reduced.

[Problems to be solved by the device]

However, in the above-mentioned conventional technology, since the discharge straw is extracted from the middle of the discharge straw conveying device for forcibly sandwiching and conveying the discharge straw, the discharge path is clogged, or the conveyance posture of the discharge straw toward the dropper is It may be disturbed and adversely affect the discharge of waste straw.

In view of the above situation, an object of the present invention is to enable the discharge straw to be simultaneously supplied to both the cutter and the long straw processing device without hindering the conveyance of the discharge straw.

[Means for solving the problem]

Therefore, the present invention is equipped with a cutter at the rear of the threshing device for shredding the discharged straw after threshing carried by the discharge straw conveying device consisting of a conveyor chain and a sandwiching rail arranged below the conveyor chain. In a combine straw discharge straw processing device that has a long straw processing device that treats the discharge straw as long culm behind, the rear end of the transport chain is positioned above the cutter and the rear end position of the sandwiching rail. Is configured to be adjustable in the front-back direction, front and rear guides that can be opened and closed are provided at the front and rear of the exhaust straw supply path to the cutter, and both guides are opened and closed to close both guides. By doing so, all the discharged straws go to the long straw processing device. When the long straws are collected, the front guide is opened and the rear guide is closed, so that the discharged straws are directed toward both the long straw processing device and the cutter. It is configured so that the shredded / recovered state and the shredded state in which the discharge straws are all directed toward the cutter by opening the rear guide can be exposed, and the rear end position of the sandwiching rail opens / closes the front guide or the rear guide It is characterized in that they are linked so as to be moved to a position suitable for each state according to the operation.

[Action]

According to the above configuration, by opening and closing the front and rear guides, a long straw recovery state in which the entire amount of waste straw is supplied to the long straw processing device, and the waste straw can be simultaneously supplied to both the long straw processing device and the cutter. It is possible to selectively set each state of the collection state and the shredding state in which all the discharged straw is shredded and returned to the paddy field.

Both the long straw processing device and the discharge straw supply to the cutter are achieved by switching the path of the discharge straw only from the rear end of the discharge straw conveying device, that is, the discharge straw conveying device itself as in the past. Since the mechanism for switching the supply path is not provided in the above, the discharge straw is not clogged and the conveying posture is not disturbed in this discharge straw conveying device.

In addition, since the front and rear guides are opened and closed by switching between the above-mentioned states, the location where the discharged straw is fed from the discharged straw conveying device changes back and forth, but after the sandwiching rail to put the discharged straw into the conveying state. Since the end position is linked to the position corresponding to each supply destination, the above-mentioned states can be smoothly performed.

[Effect of device]

Therefore, both the cutter and the long straw processing device can be used at the same time as in the conventional case due to the effect of (a), and there is no obstacle to the discharged straw conveying device due to the effect of (b). In addition, there is an advantage that the exhaust straw processing device can be operated smoothly and surely in any state by the action of c.
