Description

[Detailed Description of the Invention] [Industrial field] The present invention takes cut grass or straw into a bale forming chamber, forms a roll-shaped bale with the straw, and winds twain around the bale. Roll baler to be taken out of the machine.

"Prior Art" Conventionally, as disclosed in Japanese Utility Model Application Laid-Open No. 58-185044, there has been a technology for shaping straws by picking up straw grass from the pickup portion to the baler portion.

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, when the bale pressure in the bale forming chamber exceeds a preset value, the feeding of straw to the bale portion was stopped, so that there was an excess in the bale forming chamber. Although it was possible to prevent the straw from being fed into the bale forming chamber, the straw was collected in the front side of the bale forming chamber.Therefore, there was a problem that extra straw was taken into the baler, and the bale shaping operation could be restarted smoothly. There was a problem in handling such as not being.

"Means for Solving the Problems" However, the present invention is a roll baler for shaping a bale by incorporating straw from the pickup section into the baler section,
A sensor for detecting the bale pressure in the bale forming chamber, and a pickup clutch for controlling the operation of the pickup section,
The present invention is characterized in that the pickup clutch is configured to be disengaged via the sensor when the bail pressure exceeds a set value.

"Working" Therefore, by automatically stopping the pickup part when the bale pressure in the bale forming chamber exceeds a preset value, it is possible to prevent the pickup part from taking in excessive straw grass, and the shaped bale of the shaped bale can be prevented. It can be taken out easily, and
The bale shaping operation can be easily restarted, and the handling operation can be simplified and the safety can be improved more easily than ever before.
