[0002]

2. Description of the Related Art As this kind of working machine, for example, Japanese Utility Model Publication No.
No. 21888.

[0003]

However, in such a conventional working machine, when an attempt is made to perform an entire mulching in which the entire field is covered with a multi-film, it is not possible to carry out one simultaneous operation. Do multi-work every time,
There was a problem in work efficiency such as performing a multi-work to fill the gap at a later date.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a medicine injecting blade for injecting a medicine into a field, a multi-apparatus for coating a field surface after the injection with a multi-film, and a film after multi-film covering. A soil-covering conveyor device that covers the soil on both upper surfaces and a rubber wheel that stably holds the working machine are provided, and a soil-removing portion of the soil-covering conveyor device is located behind the chemical injection blade, and on a rear extension line of the rubber wheel. The soil discharging portion of the soil covering conveyor device is facing the same, and the wheel is used to form a groove for multi-film covering, and the soil in the groove for multi-film to be covered in the previous operation is compacted. In this way, the multi-film can be laid in a large number of rows while the edges of the multi-film are wrapped, so that the entire multi can be performed in one simultaneous operation. Further, by providing a soil leveling plate at a position rearward of the chemical injection blade so as to be capable of adjusting the inclination angle with respect to the traveling direction, the work trace on the soil surface by the injection blade can be made even.
