Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to an endless rotation band for receiving and sending a binding discharge straw that is fed laterally from a binding device, and a conveyance start end side of this endless rotation band. And a holding rail that opposes the bundle discharge straw toward the endless rotation belt side facing the conveyance surface to the side, and the bundle discharge straw sent in this endless rotation belt is vertically lowered by its stock source. TECHNICAL FIELD The present invention relates to a three-dimensional discharging device for discharging a bundle of straws that drops and discharges.

[Conventional technology]

Conventionally, as an exhaust straw bundle three-dimensional discharge device configured as described above, there is one disclosed in, for example, Japanese Patent Laid-Open No. 57-74018, and in this reference, the endless rotation band is composed of an endless chain and the combine In the rear view of the vehicle body, the endless rotation band is provided by setting the rotation axis of the sprocket around which the endless chain is wound to an angle of about 45 degrees with respect to the horizontal, and the end of the sandwiching rail is provided with an endless rotation band. A member is attached to receive the bundle discharge straw sent out from the rotation band and to correct the posture of the bundle discharge straw when it is dropped.

[Problems to be solved by the invention]

In other words, by setting the posture of the endless chain as described above, the endless chain receives the binding waste straw in the lateral posture from the binding device at its front part and changes the posture of the binding discharge straw during conveyance. In the rear part, the bundle discharging straw is discharged while being guided so as to be in a vertical posture.

However, when the posture of the endless chain is set in this manner, the endless chain is bundled in a posture inclined by about 45 degrees with respect to the conveying surface (the surface formed substantially parallel to the axis of the sprocket). Receives the bundle discharge straw from the device, and
Similarly, since the bundle discharge straw is discharged in a posture inclined by about 45 degrees with respect to the conveying surface of the endless chain, the posture change of the bundle discharge straw when sending the endless rotation band may be insufficient. If the posture change is insufficient in this way, the posture of the bundle discharge straw cannot be corrected sufficiently even if the bundle discharge straw is discharged while being guided, and therefore, the bundle discharge straw dropped on the ground. It was difficult to make the stand.

The object of the present invention is to smoothly change the posture of the bundle discharging straw in a vertical direction in a transport system composed of an endless rotation band by rational modification, and at the same time, to release the bundle discharging straw in the posture. The point is to construct the guide structure that corrects as easily as possible.

[Means for solving problems]

The characteristic configuration of the present invention is that an endless rotation band that receives and sends the binding discharge straw sent from the binding device in a horizontal position and an endless rotation band that faces the conveyance surface from the conveyance start side to the conveyance end side of the endless rotation band. A three-dimensional discharging device for discharging bundled bundles of straw bundles, which is provided with a holding rail that presses the bundled bundles of straw toward the moving belt side, and drops and discharges the bundled bundle of straws sent by this endless rotation belt in a vertical position in which the stock source is directed downward In the above, the rotation axis of the wheel body on the transport side on which the endless rotation band is wound is set substantially horizontally, and the rotation axis of the wheel body on the transport side is set substantially vertically, and,
The endless rotation band is wound around the two wheels in a state of being twisted by about 90 degrees, and the end portion of the sandwiching rail is curved so as to wrap around the wheel on the lower transfer side. The action and effect are as follows.

[Action]

If the above features are configured as shown in FIGS. 1 and 2, for example, the transport surface of the endless rotation band (13) is directed vertically in the front part of the transport system and in the left-right direction in the rear part of the transport system. Since the endless rotation band (13) feeds the bundling and discharging straw (5) along the conveyance surface of the endless rotation band (13) from the initial horizontal posture to the vertical posture. That is, since the orientation change direction of the transport surface during the transport of the endless rotation zone (13) matches the orientation change direction of the binding discharge straw (5), the posture is changed by the weight of the binding discharge straw (5) as in the conventional case. The holding rail (14) is placed in a fixed positional relationship with respect to the endless rotation band (13) without any trouble such as adjusting the position of the holding rail with respect to the endless rotation band (13) in order to make a change. The posture of the bundle discharge straw (5) can be changed simply by installing it, and the bundle discharge straw (5) can be changed. Since it contacts the end portion (14) a) of the holding rail (14) that is curved after being changed to the vertical orientation, the orientation of the bundle discharge straw (5) is not corrected during this contact, and By simply removing the feeding force, the bundle discharging straw (5) falls substantially vertically below.

[Effect of device]

Therefore, by rationally modifying the endless rotation band, the bundling / discharging straw can be smoothly changed in posture, and the guide structure at the time of discharging the bundling / discharging straw is relatively simple.

As shown in FIG. 1, a projecting piece (22) is attached to the rear end of the holding rail (14) toward the endless rotation band (13), and the bundle discharging straw (5) is conveyed. When the projecting piece (22) is crossed over, the binding discharge straw (5) is twisted around the axis of the culm as a result of which the stocker side expands and the holding rail (14).
The end portion (14a) of the is curved so as to embrace the rear wheel body (17), and the inertial force toward the rear immediately after the endless rotation belt (13) finishes the transportation is thus curved. The bundle discharge straw (5) is made to fall vertically downward by being restrained by contact with the end portion (14a).

Furthermore, at the time when the transportation by the endless rotation belt (13) is completed,
In order to promote the separation between the projections (15) of the endless rotation zone (13) and the binding discharge straw (5), the rear wheel body (17) has a disk shape with a larger diameter than this wheel body (17). Rotating member (23), (2
3) is installed.

The front wheel body (16) around which the endless rotation band (13) is wound is supported by the frame (24) and at the same time, the binding device (A).
The power from the transmission case (8) that constitutes the is transmitted via the bevel case (25) and the chain transmission mechanism (26),
Further, the rear wheel body (17) is arranged in a state of being biased in the tension direction by the tension spring (27) with respect to the frame (24).
