装置を提供する点にある。As shown in FIG. 6 of the above publication, the foliar cutting device in the above-mentioned root vegetable harvesting machine is constructed by arranging a pair of rotary blades facing each other in a vertically overlapping manner. The left and right rotary blades are rotated in opposite directions to pull the foliage and cut it. However, if foreign matter such as wood chips or stones is transported for some reason, it will be pinched and the stem-and-leaf cutting device will be locked,
There was a risk of problems such as the lack of a rotary blade and the bending of its rotary shaft. An object of the present invention is to provide a foliage cutting device in which the above inconvenience is eliminated while maintaining a good foliage cutting function.

イルに形成してあることを特徴とする。Means for Solving the Problems [Structure] A first invention for achieving the above-mentioned object is to convey a root device that is pulled out from a field in a hanging posture by sandwiching the foliage portion of the root vegetable, and this carrier device. In a cutting device structure of a root crop harvester equipped with a foliage cutting device that cuts the foliage of the root vegetables sent in, the foliage cutting device is a state in which the pair of left and right rotary blades partially overlap in the rotation axis direction. And one of the rotary blades is formed as a gear-shaped star wheel made of an elastically deformable resin material.

る。A second aspect of the present invention is a conveyor for conveying root vegetables withdrawn from the field in a hanging posture by sandwiching them, and a leaf for cutting off the root and leaves of the root vegetable sent by the conveyor. In the cutting device structure of a root crop harvester equipped with a cutting device, the foliage cutting device is configured by arranging a pair of left and right rotary blades so as to face each other in a partially overlapping manner in the rotation axis direction. The rotary shaft of one of the rotary blades is configured to be elastically bendable.

込んでロックすることが回避されるのである。[Operation] According to the structure of claim 1, when root vegetables such as carrots are conveyed, the foliage is forcibly fed by being pinched by the gear portion on the outer circumference of the star wheel, so that the foliage drawn in by the foliage is removed. You will be able to reliably cut with the rotary blade. Therefore, it is possible to exhibit a good cutting function even if some deformation occurs because it is made of resin. And even if foreign matter is conveyed, it will be pinched by the gear part on the outer periphery of the star wheel, but because it is made of resin it can be pushed away by the foreign material and the star wheel escapes and deforms, allowing the foreign matter to pass through and lock it by biting. This is avoided.

作用を発揮できるのである。According to the second aspect of the invention, when root vegetables such as carrots are conveyed, the foliage is satisfactorily cut by the pair of rotary blades as in the conventional case. When a foreign substance is conveyed, the rotary shaft is bent and deformed to one side, the rotary blade escapes and displaces, and the foreign substance can be passed through, and it is possible to avoid being caught and locked. Since the rotating shaft is elastic and bends and deforms, it can automatically return to its original straight state after passing a foreign substance, and can exhibit a good foliar cutting action again.

It was possible to provide a root vegetable harvesting machine that can avoid foreign matter biting lock and can perform harvesting work more efficiently without the need to replace a broken rotary blade in the middle.

There is an advantage that it can be incorporated into the conventional model by changing only one rotating axis.

る。[Other Embodiments] As shown in FIGS. 9 (a) and 9 (b), the foliage cutting device 8 includes a pair of left and right metal rotary blades 8.
The d and 8e are arranged so as to face each other so as to partially overlap in the rotation axis direction, and the rotation shaft 25 of the rotation blade 8e on the left side of the rotation blades 8d and 8e in the machine traveling direction can be elastically bent and deformed. It may be configured in. That is, the rotary shaft 25 is configured by connecting the proximal shaft portion 25a to which power is input and the distal shaft portion 25b having the rotary blade 8e attached to the upper end through the winding spring 26. Each shaft 25
A screw portion for mounting the winding spring 26 is formed on each of a and 25b so that the winding spring 26 can be mounted by rotating the winding spring 26.
