DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction of a soil disinfecting machine for injecting and spraying a chemical solution into soil in a field and performing a control operation.

[0002]

2. Description of the Related Art Conventionally, in a field, various control operations have been performed in order to protect agricultural crops from pathogenic bacteria and pests. In these control operations, operations for controlling harmful microorganisms include: For example, as disclosed in Japanese Utility Model Application Laid-Open No. 4-3578, a mobile agricultural machine pulls a chemical solution such as chlorpicrine in a chemical solution tank by a pump unit, and discharges and discharges the soil in the field through an injection claw. A soil disinfecting machine is used in which the soil is dispensed into the soil, the surface of the soil is crushed by a crushing wheel, and the mulch film is applied.

[0003]

However, in the above-mentioned prior art, the injected chemical liquid is converted into a harmful gas in the soil. In order to prevent the harmful gas from coming out of the surface, the chemical liquid is injected. Squeeze the surface of the later soil firmly with a crushing wheel,
The soil disinfecting machine is configured to cover the multi-film. Due to the structure of the soil disinfecting machine, the multi-film covered in the previous process and the multi-film covered in the current working process are overlapped. Harmful gasification chemical solution leaks from between the multi-film and the multi-film, and in the case of a field near a residential area, particularly in the case of a field near a residential area, an odor is trapped in the vicinity, and the occurrence of agrochemical pollution such as a bad mood is generated. It is the cause of. Therefore, the present invention is simple,
It is another object of the present invention to provide a soil disinfection apparatus capable of surely stacking the multi-film covered in the previous step and the multi-film covered in the present step.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. That is, the present invention provides a method for driving a disinfecting pump, which is driven by a mobile agricultural machine to form a groove in a field with left and right driving wheels and sprays a chemical solution into the soil of the field, and pressurizes the surface of the soil with a pressure reduction wheel. In the configuration of the soil disinfection machine that suppresses the pressure and covers the multi-film, a grooving device is installed at the front of the drive wheel, and the grooving device is stored one-touch forward.

[0005]

Next, the operation will be described. When the tractor 1 equipped with the soil disinfecting machine 3 at the rear is driven in a field, first, in the first outbound path, the left and right groovers 35 are lowered. To make two grooves on the left and right in the field,
13 rotates and depresses the groove, and at the same time, the transmission 1
The disinfecting pump 7 is driven via the
The chemical solution in the inside is sucked, pressure is applied to it, and it is discharged into the soil from the injection claws 8, 8,..., And the soil compacted by the rear wheels 40, 40 of the tractor 1 by the subsoiler 6, 6, is crushed and softened. And
The transport conveyor 31 is driven by the driving force from the tractor 1, the soil is transported upward, and the groove erasing guide 3 is moved.
Fill the groove formed at the lower end of the conveyor 31 by 3
With the leveling plate 15, the cutting groove formed by the injection claws 8, 8,... Is leveled, and the soil after the injection of the chemical solution is solidified by the pressure-reducing wheel 9 without breaking the groove pressed by the driving wheels 13, 13. The multi-film 22 is pressed and covered at the groove by the loops 24 and 24, and then the conveyor 3 is placed on the multi-film 22 at the groove.
At 1, the soil conveyed upward is guided by the chutes 32, and is dropped and buried.

After the above steps are sequentially repeated to perform the pest control operation in the forward pass step, and to perform the pest control operation in the next return pass step, the grooving device 35 on the side overlapping with the multi-film 22 covered in the forward pass step is required. It is stored and fixed to the front upper side with one touch, and a groove is formed by one of the grooving devices 35, and the control work is performed while the multi-film coated in the previous process and the multi-film to be coated in the current process are overlapped. In the reciprocating path step, the groover 35 on the side overlapping with the multi-film 22 covered in the previous step is stored and fixed above the front side, and a groove is formed by one groover 35, and the multi-films 22 The control work is performed while overlapping.
