Description

Detailed Description of the Invention "Industrial Application Field" The present invention picks up straw grass such as grass and straw scattered in a field with a pick-up section and forms it into a rolled 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 Utility Model Application Publication No. 59-188841, there has been a technique for sending twines around the outer periphery of the bale and wrapping them around the bale. "Problems to be Solved by the Invention" Since the pick-up section was operated even when the bale was being wrapped around the bale, there was a problem with the straw picked up by the pick-up section adhering to the bale in the middle of the bale, and also when the worker was picking it up. There were safety issues such as clothes getting caught when people approached the area.

[Means for Solving the Problems] However, in the present invention, the straw grass is picked up by a pick-up section at the lower front of the machine body, and the straw grass is formed into a bale by the upper and lower transport bodies disposed opposite to each other, and the bale is formed by the bundling device. The device for winding twines sent from the binding device around the outer periphery of the bale is characterized in that the movement of a runner for guiding the twines from the binding device and the drive of the pickup section are interlocked, and the pickup section is stopped during winding of the twines. That is.

"Function" Therefore, during twine winding, it is possible to prevent excess straw from being picked up by the pick-up section, and twine winding can eliminate conventional problems such as attaching straw to the subsequent bale, and Workers can work safely near the pick-up section, and since the pick-up section is stopped, driving noise during twine winding can be reduced compared to the conventional method, resulting in improvements in safety and handling functions compared to the conventional method. can be easily achieved.
