Description

[Detailed Description of the Invention] [Industrial field of application] The present invention holds the tip end side of a bundle of discharged straws bundled in a sideways posture on the discharge side of the discharged straw binding device attached to the threshing section. A holding and conveying device for conveying upward is provided, and by the holding and conveying device, the bundle of discharged straws is positioned downward with the stock straw portion side until the bundle of discharged straws is conveyed to the upper end and the bundle of discharged straws is released. The present invention relates to a combine straw discharge device that three-dimensionally discharges the discharge straw bundle by forming a standing posture.

[Conventional technology]

As this type of discharging straw discharging device, a holding and conveying chain that turns obliquely with respect to a horizontal plane (oppositely turns) on the discharging port side of the discharging straw binding device attached to the threshing unit and faces the chain. In some cases, a holding and conveying device including a holding rail arranged in parallel above is provided (for example, see Japanese Utility Model Laid-Open No. 58-152847).

Further, at the end portion of the holding and conveying device, a standing posture control guide member for collecting and storing the standing straw discharge bundle in that posture and then dropping the bundle is discharged. Was attached to the rear side of the fuselage.

[Problems to be solved by the invention]

In such a conventional discharged straw discharging device, there has been a demand for more reliable reception of the discharged straw bundle in the sideways posture on the chain start end side.

Further, since the standing posture control guide member is attached to the rear side of the machine body, there is a problem that the attached height must be a certain height or more. That is, at least the height of the lowermost end of the guide member has to exceed the height of the bundle of discharged straws standing upright in the field in a three-dimensional discharge state. This is because, when the height of the lowermost end is set lower than the height of the bundle of discharged straws standing in the field, the guide member may overwhelm the bundle of discharged straws standing in the field.

Therefore, the attached height of the guide member is set to a certain height or more, but in this case, it takes a long time for the bundle of discharged straws to stand up in the field after being separated from the guide member, so that the discharged bundle is discharged between them. There has been a problem that the standing posture of the straw bundles collapses and the probability that the discharged straw bundles will definitely stand in the field becomes low.

An object of the present invention is to provide a combine stereoscopic emission device capable of solving the above problems.

[Means for solving problems]

A feature of the present invention is that a discharging / conveying device attached to the threshing section is provided with a sandwiching / conveying device for clamping and conveying the tip end side of the bundle of discharged straws, which is bundled in a sideways posture, to the upper side thereof. By the time the conveyor device finishes conveying the discharged straw bundle to the upper part and starts discharging the discharged straw bundle, the discharged straw bundle is placed in a standing posture in which the stock base side is located downward, so that the discharged straw bundle is In a combined straw discharge device for three-dimensional discharge, the sandwiching and conveying chain for constituting the sandwiching and conveying device is configured in a substantially vertical structure, and the guide member for controlling the standing posture of the exhausted straw bundle is provided below the end portion of the sandwiching and conveying device. In addition, the guide member is arranged with the guide surface surrounding the fall path of the bundle of discharged straws falling from the nipping and conveying device on the front side of the machine body at the end portion of the nipping and conveying chain in a posture along the vertical direction. The rear end of the guide member is provided apart from the rear end of the sandwiching and conveying chain so that the surface is opened to the rear side in the traveling direction of the machine body. The point is that a gap that is open in the left-right direction is formed.

[Action]

In the discharged straw discharging device having such a configuration, since the sandwiching and conveying chain that constitutes the sandwiching and conveying apparatus is rotated substantially vertically, on the chain start end side, the bundle of discharged straws in a sideways posture is composed of the sandwiching conveying chain and the sandwiching rail. It will be easier to enter in the same posture.

Further, since the guide member for controlling the standing posture of the bundle of discharged straws provided below the terminal end portion of the holding and conveying device is provided only on the front side of the machine body, even if the height of the guide member is lowered, As a result that the guide member does not fall over the stack of discharged straw that stands up in the field, the attached height of the guide member must be a certain level or more. It surrounds the drop path of the stack of discharged straws and is open on the rear side in the machine's traveling direction, so the guide effect of dropping the stack of discharged straws in the upright posture is effectively exerted. Therefore, the angle range for guiding can be widened as compared with a simple flat guide, and more stable posture guiding action can be performed.

In addition, since a gap portion is formed between the rear end of the guide member and the rear end of the nip transport chain that is open in the left-right direction to allow the bundle of discharged straws to move in the front-rear direction, a guide member is provided. This does not hinder the falling behavior of the discharged straw bundle and allows the bundle to be dropped and supplied to the ground as desired.

[Effect of device]

Therefore, it is possible to more reliably receive the discharged straw bundle on the chain start end side, and to lower the height of the guide member sufficiently to shorten the time until the discharged straw bundle separated from the guide member stands up in the field. It is possible to prevent posture collapse and improve the standing probability. And it is possible to change the attached height of the guide member in response to the change in the culm length of the discharge straw, and
Since the existence of the guide member does not adversely affect the discharge and standing of the discharged straw bundle, the above advantages can be exhibited.
