BACKGROUND OF THE INVENTION
The present invention relates to a soil sterilizer connected to the rear part of a tractor body, and more particularly to a full-surface multi-type soil sterilizer provided with a chemical injector and a multi-film laying machine.
[0002]
[Prior art]
As a machine for laying a multi-film while injecting a medicine into a field, the present applicant has previously filed Japanese Patent Application No. 7-185572. This is a multi-film in which a rotary working machine is connected to the rear part of the tractor body, a chemical injection machine is provided between the tillage claw and the rear cover of the rotary working machine, and a multi-film feeding part is disposed behind the rotary machine. In the laying machine, a pressure reducing roller is provided across the entire width of the tilling claw between the tilling claw and the feeding portion of the multi-film.
[0003]
This multi-film laying machine injects chemicals while plowing the field with a rotary working machine as the tractor advances, and lays the multi-film by reducing the soil surface after disinfection with a pressure reducing roller.
[0004]
[Problems to be solved by the invention]
The multi-film laying machine disclosed in Japanese Patent Application No. 7-185572 described above performs chemical injection and multi-film laying while plowing with a rotary working machine. However, since the rotary working machine is provided, the longitudinal dimension becomes longer. There is a problem that the turning performance falls. In addition, some users do not need a rotary work, which causes a problem in terms of cost.
[0005]
If the rotary work machine is excluded, the overall length is shortened, but the multi-film is laid with the tractor wheel marks remaining. For this reason, the wheel trace portion is recessed during the multi-film laying operation, and the multi-film is rolled by the influence of the wind acting on the recessed portion, so that the multi-film is easily loosened.
[0006]
In addition, even if the surface tension is acting strongly immediately after laying one side edge part of the multi-film on each other, air is accumulated in the recessed part, and fluttering occurs due to the wind. In any case, the durability of the multi-film laying is deteriorated, for example, the inner soil holding the end of the multi-film is peeled off and a plurality of multi-films are lifted simultaneously.
[0007]
Therefore, when laying a multi-film while injecting chemicals into the field, technical problems to be solved to lay the multi-film so that the multi-film does not peel off by erasing the tractor wheel marks and adhering the multi-film to the soil surface. The present invention aims to solve this problem.
