Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a nodule having a knotted building, a string holder, and a string guide plate, and a stalk for winding a stalk that has been fed in a standing position in a binding space. In addition to having a needle to be attached and a discharge arm that is arranged above the knot part in an overlapping manner, the operation locus of the tip end part of the discharge arm and the discharge track that projects the bundled stems into the binding space and the binding space. The present invention relates to a stem-culm bundling device that is set in a loop with a non-operating locus that overlaps the knot portion and moves toward the anti-feeding direction outside the knot.

[Conventional technology]

Conventionally, as a stem-culm bundling device configured as described above, there is one disclosed in Japanese Utility Model Publication No. Sho 61-98440, and as shown in this reference, a bundling operation is performed in this type of stem-culm bundling device. At the end of the above step, the bundled stem culms are sent out of the bundled space by the operation of the discharge arm.

[Problems to be solved by the device]

However, as shown in the above-mentioned reference, in the case of bundling the cutting culm in a vertical posture, when the cutting culm has a granulation part in the upper end member like paddy rice, the cutting culm is fed into the binding space. In this condition, the granulation part may hang down on the non-acting locus of the discharge arm, and part of the culm falls down on the non-acting locus of the discharge arm when binding soft culms. Sometimes.

As in the stem-culm bundling device of this reference, when the bundling operation is performed, the discharging arm moves along the non-acting locus and then moves along the discharging locus. If part of the granulation part or the cut stalk of the cutting stem enters the non-acting locus of the discharging arm, the discharging arm sends the granulation part, etc. in the anti-discharging direction at the time of binding operation, so that the smooth culm of the binding stem is smoothed. Not only does it hinder the release, but it also leaves room for improvement because it may cause shedding at the grained part.

The purpose of the present invention is to construct a stem-culm bundling device that avoids contact between the discharge arm and the graining part, etc., even when binding soft culm, which is likely to cause drooping of the graining part, etc., by rational modification. There is a point to do.

[Means for Solving the Problems]

The features of the present invention are, as described at the beginning, a stem having a nodule, a needle, and a discharge arm, and the operation locus of the tip of the discharge arm is set in a loop shape between the discharge locus and the non-action locus. In the culm bundling device, a cover member is provided at a position above the knot portion and above the non-working locus so as to prevent the cutting stems from entering the non-working locus side from the binding space. The end on the binding space side is formed in a shape along the end surface on the binding space side of the string guide plate in plan view, and the action and effect are as follows.

[Action]

According to the above feature, even if the cutting stem culm sent into the binding space in the standing posture or the posture is disturbed in a form in which the grain part of the cutting culm falls to the side of the non-acting locus of the discharge arm, The contact suppresses the disturbance of the posture, and the contact with the cover member prevents the collapsed portion from entering the non-acting locus of the discharge arm. Further, since the end portion of the cover member on the binding space side is formed in a shape along the end surface of the string guide plate on the binding space side in plan view, regardless of the provision of the cover member, the cutting stem culms can be discharged smoothly. In addition, since the cutting culm can be brought into contact with the end surfaces of the string guide plate and the cover member on the side of the binding space, the posture disturbance can be further suppressed even if the cutting culm is soft.

[Effect of device]

Therefore, even if the cutting culm is weak, the posture of the cutting culm can be properly maintained by a relatively simple modification by providing a cover member to avoid contact between the discharge arm and the graining part, and to smooth the cutting culm. In addition, a stem-culm bundling device that discharges the bundled stem-culm without causing shedding was constructed.
