Description

[Detailed explanation of the invention] Conventionally, when pulling burdock from the soil, short-rooted burdock can be easily pulled out by cutting corners;
Long roots require time to dig, require a considerable amount of effort to pull out, and often have to be cut in the middle of being pulled out.

This invention aims to eliminate the above-mentioned drawbacks in a simple way.

If this idea is explained with a diagram, it will be about 13 years long.
As shown in Figure 1, the inside upper parts of L-shaped mounting plates 2 and 2' are attached to the center of the outer periphery of semicircular arc bodies 1 and 1' of the same shape, which are cut from the vertical center of a short cylinder with an inner diameter of about 4 cm. The outer base parts 3 and 3' are approximately 120 cm long as shown in Figure 2.
By welding one side to the upper end of the operating handle rods 4 and 4' facing each other so that they are on the same plane, and joining the semicircular arc bodies 1 and 1' in an annular shape,
The abdomens of the L-shaped mounting plates 2 and 2' are mutually overlapped, and the bolt 5 is passed through the washer 6 as shown in FIG. At this position, screw the nut 7 to such an extent that the operating handle rods 4 and 4' can be easily opened and closed using the bolt 5 as a fulcrum, and then tighten the retaining nut 8 to form a sash-like shape. The other ends of the rods 4 and 4' are notched to an appropriate length to form anti-slip portions 9 and 9'.

This invention has the above structure.

To explain how this device works, when removing burdock in the field, the soil on one side of the burdock is usually dug and pulled out, so one side naturally forms a ridge. First, by opening the operating handle rods 4 and 4' to the left and right, the semicircular arc members 1 and 1' simultaneously open using the bolt 5 as a fulcrum, and the operating handle rod 4 is placed at an appropriate position on the bulrush root with the semicircular arc members 1 and 1'. and 4' to close and hold the burdock. At this time, to prevent damage to the burdock, the inner surfaces of semicircular arcs 1 and 1' are appropriately covered with cloth. Next, use the ridges as a base to operate the operation handle. The levers 4 and 4' are used as leverage to pull the burdock out. By using the leverage method, the trench does not have to be deep, and the burdock root held between the semicircular arcs 1 and 1' is not damaged, and the tip of the burdock is not damaged. The amount of skill required is about half that required on hand, which reduces labor and has great effects such as maintaining quality and speeding up harvesting.
