Since the upper pull-in roller is elastically biased to rotate downward from the discharge side toward the supply side, the insertion resistance of the upper pull-in roller becomes large, and the insertion work cannot be performed easily, resulting in heavy labor. It was

Further, since the upper pull-out roller is elastically biased to rotate downward from the supply side toward the discharge side, the cane stalk can be sufficiently pressed against the lower pull-out roller side according to the change in diameter. As a result, there is a problem that it is impossible to reliably pull out the rollers due to the narrow pressure.

(D) Means for Solving the Problem Therefore, in the present invention, a sugar cane stalk that forms a part of a box-shaped case and is supplied from the outside between the front and rear walls facing each other with a certain distance in the front and back. A pair of upper and lower pull-in rollers that pinch inward from above and below, and a pair of upper and lower remover rollers that remove leaf sheaths attached to the cane stalks pulled in by the pull-in rollers from above and below. In a leaf-stripping device that axially supports a pair of upper and lower pull-out rollers that sandwich the cane stalks and the like that have been defoliated by the leaf rollers from above and below and pull out outward, In order to freely change the vertical distance from each roller according to the diameter of the cane stalk, each base end is attached to the tip of the roller support arm pivotally supported on the front wall or the rear wall, and is supported for vertical rotation. And support the pull-in roller Roller support arms,
The roller is configured to rotate downward from the supply side of sugar cane, etc. toward the discharge side, and the support arm that supports the pull-out roller is configured to rotate downward from the discharge side to the supply side. In addition, the leaf removing device is characterized in that the wall opposite to the wall that pivotally supports the roller support arm is detachable.

(E) Action / Effect In the present invention, since the roller support arm for supporting the upper pulling roller is configured to rotate downwardly from the supply side of sugar cane and the like to the discharge side, the work is performed. When a person manually inserts sugar cane, etc. between the upper and lower pulling rollers and supplies it, the upper pulling roller does not act as an insertion resistance and the sugar cane can be easily inserted, greatly reducing labor. can do.

Further, since the roller support arm that supports the upper pull-out roller is configured to rotate downwardly from the discharge side of sugar cane stalks and the like toward the supply side, sugar cane stalks having various diameters are also provided. It is possible to surely perform the withdrawal by the narrow pressure of both rollers by pressing the lower withdrawal roller side.

Therefore, according to the defoliation device of the present invention, the efficiency of defoliation of sugar cane stems and the like can be further enhanced.

Further, since the wall on the side opposite to the wall on which both arms are attached is detachable, maintenance and cleaning of each roller and replacement of the leaf removing brush of the leaf removing roller are easy by removing the wall. You can do it.
