Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a root cutting machine.

(B) Conventional technology Conventionally, the left and right discs with root cutting teeth formed on the outer periphery were attached to the rear of a walk-behind agricultural working machine, while traveling with the cultivator.
There was a root cutting machine that rotated the left and right discs forward with power to cut roots such as millet that were interposed between the left and right discs.

(C) Problems to be solved by the device However, since the left and right discs are rotating in the forward direction due to power, a forward force is generated in the discs, which deteriorates the straightness of the aircraft and corrects the traveling direction. Therefore, even if the left and right side clutches are disengaged, there is a drawback that the direction correction cannot be effectively performed due to the forward force.

(D) Means for Solving the Problems In the present invention, in the root cutting machine equipped with the left and right disks having root cutting teeth formed on the outer periphery behind the walking type working machine, the left and right disks are formed in a bay shape. , The front end side is wider than the rear end side in a substantially octagonal shape in a plan view, and left and right resistance rods are vertically installed at the rear end of the machine body, and the lower portions of the left and right resistance rods are respectively located on the lower rear sides of the outer surfaces of the left and right disks. The purpose is to provide a rooting machine characterized by being close to each other.

(E) Action / Effect In this device, the left and right discs are formed in a bay shape, and the front end side is arranged in a substantially eight-character shape in plan view wider than the rear end side.
When root cutting is performed with the left and right disks straddling a crop, soil is mixed back, and the top soil and the soil inside are replaced, so that soil can be activated.

Moreover, since the soil is moved inward and upward by the left and right discs, soil can be collected at the same time.

Also, since the left and right resistance rods plunge into the soil of the field, resistance is generated at the rear of the machine, improving straightness, and when the side clutch is disengaged, the walking type tiller runs on the side where the clutch is disengaged. The driving force of the wheels is lost, and the forward driving force of the traveling wheel on the opposite side and the resistance force of the resistance rod generate a rotational moment of the vehicle body, and the side clutch can effectively correct the direction.

Therefore, since the machine body does not meander or sway, the above-mentioned root cutting effect and the effect of soil mixing and soil mitigation can be further increased.

Further, since the lower portions of the left and right resistance rods are respectively brought close to the lower rear portions of the outer side surfaces of the left and right discs, it is possible to prevent the cut roots and leaves from being caught in the resistance rods.
