Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, in the field, various control work has been carried out in order to protect agricultural crops from pathogenic bacteria and pests. Among these control work, the work for controlling harmful microorganisms is For example, as in the technique described in Japanese Utility Model Laid-Open No. 4-3578, a chemical solution such as chlorpicrin in a chemical solution tank is drawn by a mobile agricultural machine, sucked and discharged by a pump unit, and the soil in the field is discharged through an injection claw. A soil disinfecting machine is used in which the soil is injected and dispersed, the surface of the soil is crushed by a crushing wheel, and the soil is covered with a mulch film.

[0003]

However, in the above-mentioned prior art, the injected chemical solution is turned into harmful gas in the soil, and in order to prevent the harmful gas from coming out from the surface, the chemical solution is injected. Compress the surface of the soil afterwards with a compression wheel,
The soil disinfecting machine is configured to cover the mulch film. Due to the structure of the soil disinfecting machine, it is possible to overlap the mulch film coated in the previous step with the mulch film covered in the current step. Since it can not be done, the harmful gasified chemical liquid leaks from between the mulch film and the mulch film, and especially in the case of a field near the residential area, a bad odor is generated in the vicinity, and the pesticide pollution such as feeling uncomfortable occurs. It becomes a cause. In addition, since the conventional soil disinfecting machine is provided with a compression wheel, a mulch film, etc. in sequence, the total length becomes long, and there is a lot of headland when turning in the field, resulting in a problem that work efficiency becomes very poor. It occurs. Therefore, an object of the present invention is to configure a soil disinfecting apparatus that can easily and surely cover a mulch film and can easily swivel.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, the present invention is towed by a mobile agricultural machine, drives the disinfection pump with the left and right drive wheels, suppresses the surface of the soil with a compression wheel while spraying the chemical solution into the soil in the field, and mulch film In the soil disinfecting machine to be covered, a compression wheel is installed inside the drive wheel.

[0005]

Next, the operation will be described. When the tractor 1 with the soil disinfecting machine 3 mounted on the rear side is run in the field, first, the drive wheels 13 and 13 rotate to make a groove in the field and at the same time to transmit the transmission. The disinfection pump 7 is driven via the device 12,
The chemicals in the tanks 25 and 25 are sucked into the tanks 25 and pressure is applied to the sub-soilers 6.6 to discharge them into the soil.
By the driving force from the tractor 1, the soil compacted by the rear wheels 40 of the tractor 1 is destroyed and expanded.
The conveyor 31 is driven to convey the soil upward, and the groove erasing guide 33 is used to fill the groove formed at the lower end of the conveyor 31, and the flat plate 15 is formed by the injection claws 8 ... The cut grooves are leveled, and the soil after the chemical solution is injected is compacted by the compression wheel 9. At this time, soil is spilled from both ends of the compression wheel 9, and the spilled soil is driven by the drive wheel 13.1.
By being regulated by 3, it is possible to suppress the drive wheels 13 and 13 without filling the groove formed in the field. Next, the mulch film 22 is pressed on the tread wheels 24, 24.
Is held at the groove formed by the drive wheels 13 and 13 to cover the field after injecting the chemical liquid, and then is conveyed upward by the conveyor 31 onto the mulch film 22 at the groove. The soil is guided by the chute 32 and dropped and dropped. By sequentially repeating the above steps, it is possible to perform the field control work.

9, a drive shaft is provided in the pipe 29, and the drive force from the tractor 1 is transmitted to the drive shaft via the universal joint 30. A conveyor 31 for conveying the soil upward is driven via a transmission shaft 45 projecting upward.

The soil conveyed by the conveyor 31 is
The treading wheels 24, 24 are supported via a support frame 47 in a state of being inclined in the two rear lower directions, and the lower end thereof is supported by the treading wheels 2.
It is guided by the chutes 32, 32 extended so as to be located at a position rearward from the 4.24, and is dropped to the place where the tread wheels 24, 24 are pressed on the covered mulch film 22. Further, on both sides of the lower part of the conveyor 31, there are arranged groove erasing guides 33, 33 for erasing grooves formed by the lower end of the conveyor 31 contacting the field, and the groove erasing guides 33, 33 are Transport conveyor 3

The transport conveyor 31 has a lower end located forward of the flat plate 15 in the front-rear direction at the center of the machine body, and is arranged in a state of being inclined rearward and upward, and the upper end of the transport conveyor 31 is provided behind the transmission shaft 45. The ends are connected.

In the above structure, when the tractor 1 is run in the field and the soil disinfecting device 3 is towed in order to perform the control work in the field, first, the drive wheels 13, 13 rotate to form a groove in the field. Simultaneously with the application, the disinfection pump 7 is driven via the transmission device 12, sucks the chemical solution in the tank 25, applies pressure, and discharges it from the injection claws 8 ... The soil that has been compacted by the rear wheels 40, 40 of the tractor 1 is destroyed by 6 to make it loose.

The driving force from the tractor 1 transmitted through the universal joint 30 drives the conveyor 31 to convey the soil upward, and
The groove removing guide 33 fills the groove formed at the lower end of the conveyor 31, and the leveling plate 15 fills the cutting groove formed by the injection claws 8 ... At, the soil after injecting the chemical solution is crushed and the soil is compacted. At this time, soil is spilled from both ends of the crushing wheel 9, but the spilled soil is regulated by the drive wheels 13 and 13, so that the drive wheels 13 and 13 do not bury the groove formed in the field. You can do it.

Then, next, the mulch film 22 is pressed by the treading wheels 24, 24 at the groove formed by the drive wheels 13, 13 to cover the field after injecting the chemical solution, and then the groove The soil conveyed upward by the conveyor 31 is dropped onto the multi-film 22 by being guided by the chutes 32. In this way the injection claws 8 ...
The chemical solution is injected into the soil through the sprayer, the soil is leveled by the leveling plate 15, the packing is pressed by the compression wheel 9, the mulch film 22 is covered, and the transfer conveyor 31 and the chute 32, 32 are used for soiling. By repeating the procedure sequentially, it is possible to perform the field control work.

[0017]

Since the present invention is constructed as described above, it has the following effects. That is, by installing the presser wheel inside the drive wheel, when the presser wheel presses down the upper surface of the field after the chemical solution injection, it is possible to perform the work without breaking the groove formed in the field by the drive wheel. Therefore, it is possible to press the mulch film in the groove that was attached with the drive wheel with the tread wheel to cover it, and lay it on it.
Further, since the mulch film can be surely covered by the soiling, it is possible to prevent the mulch film from peeling off due to external pressure such as wind and rain, and to prevent leakage of the harmful gasified chemical solution. It can be prevented. Further, since the soil disinfecting apparatus has a shorter total length than in the past, it is possible to easily make a turn in the field and improve work efficiency.
