Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a threshing device, in which a waste straw treating device is pivotally connected to a rear part of the threshing device so as to be swingable around a longitudinal axis, and the waste straw treating device is threshed. It is provided so that it can be switched between a working posture in a closed state and a non-working posture in an open state with respect to the device, and the transporting and discharging straw is extended upward from the discharging straw conveying device on the threshing device side to the discharging straw processing device. The present invention relates to a combine in which a stretchable guide rod for guiding is installed.

[Conventional technology]

Conventionally, the guide rod in the above-mentioned combine is a front guide rod pivotally supported on the fuselage side, and a rear guide rod pivotally supported on the waste straw processing device side and capable of being fitted to the front guide rod in the working posture. The front and rear guide rods are configured such that each pivot point is urged by a spring in the axial direction of the pivot axis.

[Problems to be solved by the device]

In the above-mentioned conventional technique, the discharge straw processing device can be oscillated while the guide rod is provided, and the front and rear guide rods are fitted to each other by the opening operation of the discharge straw processing device by the biasing force of the spring at each pivot. It is intended that the state at the time when the connection is released can be maintained so that the front and rear guide rods can be automatically re-fitted by subsequently closing the discharge straw processing device.

However, since the front and rear guide rods are merely spring-biased at their pivot points, they tend to be easily displaced when an external force acts on these guide rods. In most cases, it was not possible to automatically re-engage due to the impact caused by the movement, contact with other objects during maintenance in the open state, and the like.

Therefore, when closing the waste straw processing device, the operator must position the front guide rod and the rear guide rod so that the front guide rod and the rear guide rod can be fitted each time, which is bothersome and inadvertently fitted. There was a problem in that it would cause problems in forgetting straw treatment.

The present invention aims to eliminate the above-mentioned problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides the combine straw discharge treating structure described at the beginning, wherein the guide rod is pivotally supported on the front guide rod pivotally supported on the fuselage side and on the exhaust straw treating device side. And a rear guide rod that can be fitted to the front guide rod in the working posture, and one of the front and rear guide rods is provided with a guide member for shortening and urging the guide rod. It is characterized in that it is connected to the tip end of the other guide rod so that the front and rear guide rods are automatically brought into a fitted state in the working posture.

[Action]

According to the above configuration, the guide tool provided on one guide rod always urges the other guide rod to guide and pull the two guide rods so that the guide rods are in a fitted state. By closing the processing unit, the front and rear guide rods can automatically and surely reproduce the fitted state.

[Effect of device]

Therefore, it is possible to realize a waste straw processing unit having a high practical value because the troubles associated with the closing operation of the waste straw processing unit as in the past are eliminated and the guide rods are not forgotten to be fitted. .

Further, as a means for that purpose, it is sufficient to attach a guide member for shortening and urging, so that it is not necessary to significantly change the conventional form, and it is economically possible.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 3 show a combine harvester (1) provided with a waste straw processing device (2) at the rear part of the threshing device (1) pivotally connected so as to open and close about a vertical axis (P). It is shown.

The discharged straw processing device (2) is a cutter binding machine having a discharged straw binding device (4) at the rear of the discharged straw cutter (3), and this discharged straw processing device (2) is used as a threshing device (1). On the other hand, it is provided so as to be freely switchable between a working posture in a closed state and a non-working posture in an open state, and transporting waste straws from the discharging straw transporting device (5) on the threshing device side to the binding machine (4). A guide rod (6) for guiding from above is installed.

More specifically, the guide rod (6) is provided with the transfer device (5).
And a front guide rod (8) pivotally supported on the support frame (7) by the vertical axis, and a cord guide (9) of the binding machine (4) by the vertical axis, and in the working posture, It is composed of a front guide rod (8) and a rear guide rod (10) which can be fitted to the front guide rod (8), and is wound around the front guide rod (8) to form a wire (1
A guide tool (11) for urging and shortening 3) is provided, and the tip of the wire (13) is connected to the tip of the rear guide rod (10) through the inside of the front guide rod (8).

When the guide tool (11) is described in detail, as shown in FIG.
A wire (13) is wound around a drum (12) which is urged to rotate in one direction by a spiral spring, and the wire (13) is opened near the pivot of the front guide rod (8). It is inserted into the rod through the hole (14), and its tip is connected to the rear guide rod (10).

To explain the operation, when the waste straw processing device (2) is in the operating state, as shown in FIG. 1, the rear guide rod (10) has a certain fitting length in the front guide rod (8). The guide rod (6) is fitted and has sufficient rigidity to guide the discharge straw to the binding machine (4).

As shown in FIG. 3, the wire (13) urged for winding always moves the rear guide rod (10) to the front guide rod even when the exhaust straw processing device (2) is swung to the non-operating posture. Since it is pulled so as to fit into the inside of (8), the front guide rod (8) and the rear guide rod (10) are automatically moved by the wire (13) when the discharge straw processing device (2) is closed again. Are refitted to.

As shown in FIG. 4, a transportation hydraulic cylinder (16) which can be vertically swung by a lifting hydraulic cylinder (15) is provided at the rear of the threshing device (1). If the working device (2) is supported on the rod end of the carrying hydraulic cylinder (16) and each hydraulic cylinder (15), (16) is operated, the work for attaching and detaching the heavy working device (2) to the machine side can be performed. It will be easier to do.

[Another embodiment]
