Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a roll baler for collecting collected grass such as mowed grass and threshing left on the ground, and compressing and packing the collected bales into roll bales. The present invention relates to a twine supply device that winds twine around the entire width of a bale compression-molded into a roll in a bale molding chamber.

(Prior Art) For example, a roll baler's twain supply device is,
No. 2-53659 and Japanese Utility Model Laid-Open No. 61-193739.

The structure is such that a delivery roll that forcibly supplies the twine into the bale formation chamber and a twine guide that hooks the twine that comes out of this delivery roll are provided on the side of the bale formation chamber, and the twine guide reciprocates left and right. However, the position where the twain is wrapped around the bale is set to be the full width of the bale.

(Problems to be solved by the invention) In the above-mentioned twine supply device, the twine that has passed through the delivery roll is hung down through a guide formed of an annular ring, and the drowned twine is fed into the bale forming chamber and then moved laterally. I try to hook it with a guide.

For this reason, when the towine is put into use, it is first passed between the delivery rolls and into the annular ring of the guide, which is near the bale-forming chamber and therefore the straw. Fine debris, such as debris, can become lodged in the annular ring, which can make it difficult to pass the twine through the ring. Also, if the twain is flexible, it is difficult to insert it into the annular ring.

(Means for Solving the Problem) Therefore, in the present invention, the twine (T) fed out into the bale forming chamber 1 by the delivery rolls 2 and 3 is hooked by the twine guide 4 which reciprocates left and right to be guided left and right. , A twine feed device for a roll bale in which the twine (T) is wound around the entire width of the bale (B), and a vertical slit groove which is opened between the delivery rolls 2 and 3 and the twine guide 4 in the vertical direction. 5 is provided with a guide body 6 and a twine receiving member 7 is provided below the body 6 between the delivery rolls 2 and 3 and the twine guide 4.

(Operation and Effect of the Invention) The twine (T) passed between the delivery rolls 2 and 3 is put on the twine receiving member 7 through the slit-shaped guide groove 5 of the guide body 6 and the tip thereof is hung down, and the twine (T ) Will be pulled by the tow wine (T) wrapped around the bale (B) and guided by the guide groove 5.
Is a vertical slit-like shape with the lower part open,
Straws and the like are less likely to collect, and it is easy to insert the twine (T).
