DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management machine for performing management work in a house, and more particularly, to a slender U-shaped cultivation floor for producing crops such as melon which are susceptible to microorganisms and pests. The present invention relates to a management machine which forms a ridge by forming a cultivation medium and plowing the cultivation medium.

[0002]

2. Description of the Related Art Conventionally, to cultivate crops that are susceptible to microorganisms such as melons and pests, the fields in a house have been disinfected with pesticides, and then planted and grown. It is difficult to disinfect the soybean, and it may be harmed by insects, and may cause Tsurugare disease, Tsuruware disease, downy mildew, powdery mildew and the like. In recent years, in order to cultivate melon, ridges are cultivated on cultivation beds that are isolated above the ground surface so that the effects of disease and insect damage are reduced.

[0003]

However, in order to cultivate the soil in the cultivation floor which is higher than the above-mentioned surface, a light and small management machine is used, but no ridge can be formed. . In addition, it is difficult to run on a U-shaped floor arranged higher than the ground surface, and it is also difficult to plow all corners.

[0004]

SUMMARY OF THE INVENTION In order to solve such problems, the present invention drives a tilling rotor from a transmission case of a control device via a power transmission case, and mounts a support body behind the transmission case. Protrudingly laying the support frame horizontally, arranging guide rollers on both sides of the support frame,
The machine body is supported by the guide rollers, and the guide rollers are capable of adjusting the horizontal position and the vertical position with respect to the support frame.
