Description

Detailed Description of the Invention "Field of Industrial Application" The present invention picks up straw grass such as grass and straw scattered in a field in a pick-up section and forms a roll-shaped bale in a bale-forming chamber. The present invention relates to a roll baler in which the materials are bound by twines supplied from a binding device.

"Prior Art" Conventionally, as shown in Japanese Patent Application Laid-Open No. 149613/1983, there has been a technique in which a veil is formed and a twine is wrapped around the outer periphery.

``Problems to be Solved by the Invention'' In the prior art, the bale was taken out by opening the rear or upper part of the bale forming chamber, but it was necessary to greatly displace the conveyor in the bale forming chamber to unfold it. It is not easy to simplify the bale forming chamber, and with the structure in which the rear of the bale forming chamber is opened, it is not possible to easily arrange a walking type operation unit at the rear of the bale forming chamber, and the upper part of the bale forming chamber cannot be opened. This structure had some problems, such as the need to lift the bale to take it out.

Therefore, by configuring the bale forming chamber to take out the bale from the side, each of the above-mentioned problems can be resolved. However, since the end of the twine winding is fixed after the twine is taken out, the winding direction of the end of the twine winding is the same as the direction in which the bale is taken out. If the bale is oriented in the same direction, there are problems such as the end of the twine winding loosening when the bale is taken out, and the bale becoming easily deformed.

"Means for Solving the Problems" However, the present invention comprises a bale forming chamber having a conveyor and a twine guide body that reciprocates from side to side, and a bale is moved in the left and right width direction on the outer periphery of the bale in the bale forming chamber via the twine guide body. In a roll baler for winding twine, a bale discharge part is provided on either the left or right side of the bale forming chamber, and the twine winding is completed by moving the twine guide in a direction away from the bale discharge part. Features.

``Function'' Therefore, by taking out the bale from the bale discharge part on one side of the bale forming chamber, it is possible to easily arrange the walking type operating unit at the rear of the bale forming chamber compared to the conventional method. In addition, the conveyor and bale forming chamber can be simplified more easily than before, and the winding direction at the end of the twine winding is opposite to the direction in which the bale is taken out from the bale discharge section. This makes it easy to prevent the end of the twine winding from loosening during bale removal, simplifying the bale removal work and preventing the bale from deforming.
