DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-in-one multi-soil disinfecting machine for coating an entire surface of a soil with a multi-film while injecting a disinfecting solution into soil in a field.

[0002]

2. Description of the Related Art Conventionally, a multi-surface soil disinfecting machine has been used to enhance the disinfecting effect without disinfecting liquid injected into the soil of a field, evaporating and gasifying, leaking to the ground surface, and having no adverse effect on the human body. After the injection, the surface of the ground is covered with a multi-film. And furthermore, so that gas does not leak from between the laid multi-film and multi-film,
In the process after the return route, the multi-film is laid so that one side thereof overlaps. In this way, one side is overlapped, and
In order to lay the multi-film so that the tires do not step on it, a multi-film wider than the vehicle width was laid.

[0003]

However, when the multi-film is wider than the vehicle width, there are restrictions on the transfer, such as passage at the entrance of the house field and traveling when the field is a narrow road. In addition, in the configuration where multiple multi-soil disinfecting machines are suctioned by multiple disinfectant pumps and multiple injections are made, the hose on the suction side is inserted into the mouth of one chemical tank, so it takes time to replace the chemical tank and disinfect. The liquid evaporates and easily diffuses into the outside air, which may adversely affect the operator. Conventionally, a full-scale multi-soil disinfecting machine is integrated with a subsoiler, a device for injecting a soil disinfecting solution into the soil of a field, and a device for covering the entire soil surface with the disinfecting solution with a multi-film, and separated. Since it was not possible to move the multi-film covered in the previous process, the moving agricultural machine in the next process did not step on the multi-film covered in the previous process, so that one hem of the multi-film laid on the laid multi-film overlapped sufficiently. It was difficult to provide a sufficient margin in the width direction.

Specifically, for example, if the rear wheel tread of a mobile agricultural machine is 1000 mm and the tire width is 300 mm, the outer width of the rear wheel tire is 1300 mm, and one skirt of the multi-film laid on the laid multi-film overlaps. Also, if a sufficient margin is provided in the width direction so that the moving agricultural machine in the next step does not step on the multi-film covering the entire soil surface in the previous step, the multi-film width is one side of the outer width of the rear wheel tire. A total thickness of about 600 mm at 300 mm results in a multi-film width of 1900 mm or more.
Generally, the interval between the injection nails is 300 mm due to the effect of the disinfectant.
It is an interval, the number of the injection claws is 4 and the working width is 1200 mm
In this case, the intervals between the injection claws in the previous step and the next step are not equal, and the number of the injection claws is insufficient.

In order to satisfy this, the working width is 1800 mm when the number of the injection claws is six, and the film width is 300 times larger than the working width in consideration of the overlapping portion of the multi-film.
mm, and the multi-film width needs to be 2100 mm. When a full-scale multi-soil disinfecting machine using a wide multi-film is attached to the rear of the mobile farming machine in this way, there are restrictions on transportation, such as when passing through a house field entrance or running on a narrow road to the field. is there.
