TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tillage machine for an elevated cultivation floor for cultivating cultivation soil on an elevated cultivation floor that can be farmed at a position higher than the ground.
[0002]
[Prior art]
Traditionally, crops were cultivated on the ground. For this reason, the worker must perform the agricultural work in a low posture where the worker leans down or places a burden on the knees and waist, such as the middle waist, and the situation is particularly severe for elderly workers. . Therefore, in recent years, an elevated cultivation bed which is provided at a position higher than the ground and allows a worker to perform agricultural work while standing has been developed and is being established. This is generally done by using a synthetic resin such as polystyrene foam as a material, providing a deep groove inside the upper surface of which has a U-shaped vertical section, and connecting a floor frame, which is extremely long in one direction, continuously in the longitudinal direction and mounting the groove. For example, a plant, such as a strawberry, is planted and grown on the cultivation soil filled in the soil.
However, the above-described elevated cultivation floor is poor in workability because the management of the cultivation floor, for example, the plowing operation of the cultivation soil, was manually performed by a worker using an agricultural tool such as a scoop in an upright position. However, there is a problem that the burden of the labor is not reduced so much.
Therefore, in order to solve the above-described problems, an invention described in JP-A-2001-352801 has been proposed as a tillage device for an erecting cultivation floor, which performs tilling work of an erecting cultivation floor with a machine instead of manual work in order to solve the above problems. I have.

There has been a problem that the tillage device cannot be easily operated because it has to be moved along the floor frame longitudinal direction.
In addition, since the tilling blade is formed as a straight blade when viewed from the front, only the portion of the cultivating soil corresponding to the tilling blade can be tilled, and the portion corresponding to between the tilling blades cannot be tilled. There was a problem that it was not possible to till uniformly.
In view of the above, the present invention has been made in view of the problems of the related art, and includes a wheel for moving the movable cart by rotating on the left and right floor frames opposite to the cultivation floor, a motor and the prime mover and the prime mover. By providing a tilling device that performs tilling work by the drive of, and a guide plate to prevent falling wheels, it is possible to stably move on the cultivation floor without falling from the floor frame and move the position of the tilling blade.
