Abstract

(57) [Abstract] [PROBLEMS] There are a type in which the tines are forcibly rotated to weed between the plants, and a type in which the upper side of the ridge or the side of the ridge is pulled by the tine in the traveling direction of the tractor. In the former, the height of the ridges is not constant, and the depth of the tines is not stable, which can damage the crop and cause uneven weeding. The latter cannot scrape grass from between the stocks. SOLUTION: A main frame portion 2 and a tine portion 3 are constituted, and the main frame portion 2 is constituted by a frame 2A which is adjustable in expansion and contraction, a mounting bracket 2B for a cultivator 4, a moving weight 2C, and a tine portion supporting metal member 2D, The tine portion 3 is composed of a support leg 3A and a tine body 3B,
The tine body has a large number of tine units radially extending from a disk-shaped base that rotates as it progresses.

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. 1. When a part of the tines in the tyne group comes into contact with the ground, the disk-shaped substrate rotates, and as a result, other tines come into contact with the ground and scrape the grass from the stumps to the ridges. 2. With reference to FIGS. 5 and 6, the length of the tine simple substance 3B31 and the interval between the tine simple substances can be adjusted by rotationally moving the disc-shaped base 3B2. With this, the bending strength of the single tine 3B31 can be adjusted. 3. Since the tine body 3B can be tilted and moved freely, the adjustment can be made to suit each crop. 4. Since the movable weight is attached to the frame 2A which is adjustable in expansion and contraction, the supporting height of the tine body 3B can be adjusted to a state suitable for the soil. Further, since the frame 2A, which is adjustable in expansion and contraction, has its own height with the horizontal pin 2B1 as a fulcrum, the tine body 3B can be kept at a constant depth. 5. It can be easily installed and removed by using the mounting bracket suitable for various cultivators. 6. Since it is independent, it can be installed according to the number of ridges.
