Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weed control machine for golf courses and the like.

The present applicant previously proposed a weeding machine that can mechanically weed the weeding that has conventionally been done manually. This weeding machine has a weeding rotary cylinder and a gripping roll that rotates following the rotation of the weeding rotational cylinder, rotates the weeding rotational cylinder to capture the upper part of the weeds, and pulls out the weeds in cooperation with the gripping roll. This is how it was done. Since the weeding machine mentioned above picks up weeds at the point of contact with the weeding rotary body and the gripping roll, the contact point is higher than the ground surface due to its structure. Since the upper part of the grass is pulled, there is a risk that the grass cannot be pulled from the root and may be cut in the middle, and there is also a drawback that the removed grass gets tangled with the gripping roll.

The first object of the present invention is to eliminate the above-mentioned drawbacks, and by moving the position for taking in and pulling out weeds closer to the ground surface, it is possible to handle even short grass, and by increasing the contact surface of the grass clamping body. To provide a weeding machine which allows the pulling force to be applied to the grass for a longer time and prevents the pulled out grass from getting entangled.

The second object of the present invention, in addition to the first object, is to provide a movable cutting blade for aligning and bundling the grass and cutting around the roots before pulling out the weeds. To provide a weeding machine capable of pulling out weeds with their roots.

Embodiments of the present invention will be described below with reference to the drawings.
