[0001]

BACKGROUND OF THE INVENTION The present invention relates to a full-scale multi-soil disinfecting machine for injecting a disinfecting solution into soil in a field while covering the entire soil surface with a multi-film, and mounting a chemical spraying device above the soil-covering conveyor device, The present invention relates to a drive structure of a chemical spraying device and a support structure of a chemical spraying device for disinfecting soil covering both sides of a mulch film.

[0002]

2. Description of the Related Art Japanese Patent Application No. 5-175627 is a conventional technology for soil disinfecting machines. These are not equipped with a device for disinfecting soil covered soil for pressing both sides of the mulch film covering the field scene, but installed a chemical spray hopper for disinfecting soil covered soil above the soil conveyor device. In this case, for example, JP-A-5-13082
The technique of No. 4 requires a drive device that independently drives the drive shaft of the drug spraying device, a transmission device, and a drug spraying device support portion.

[0003]

The soil conveyed by the soil-covering conveyor device and the soil-covering device in the above-mentioned conventional full-scale multi-soil disinfecting machine is not soil-disinfected, and the soil is a mulch film covering the entire soil surface. Since both ends are covered with soil, when the mulch film is peeled off after soil disinfection work and cultivated for degassing, soil covered and undisinfected soil are mixed into the whole and the soil disinfecting effect is reduced.

Further, in order to disinfect the soil from the soil covering conveyor device and the soil covering device, when the chemical spraying device is mounted above the soil covering conveyor device, the chemical spraying device must be driven independently. The power transmission device up to the drug spraying device and the support portion of the drug spraying device are separately required, and the structure is complicated to operate the drug spraying device.

[0005]

In order to solve the above-mentioned problems, the structure is as follows. In claim 1

A soil-covering container that takes in soil for covering the soil on both sides of the film.
On the bare device, disinfectant particles on the soil to be covered above the intake.
In addition to disposing a drug spraying device for spraying a drug , the pump shaft of the disinfectant solution pump and the feeding shaft of the drug spraying device are directly driven coaxially. According to a second aspect of the present invention , in the soil disinfecting machine according to the first aspect, the feeding shaft of the chemical spraying device is connected to the pump shaft of the disinfectant solution pump via a coupling to support the chemical spraying device and the soil disinfecting machine. The supporting arm is projected from the mounting frame, and the supporting arm stops the rotation of the medicine spraying device about the feeding shaft.

[0006]

The operation of the present invention will be described. When the full-scale multi-soil disinfecting machine is pulled and moved forward by the mobile agricultural machine, the pump drive wheel is rotated, and the pump shaft of the disinfectant solution pump and the feeding shaft of the chemical spraying device are simultaneously driven through the transmission device, thus driving the disinfectant solution pump. Injects the disinfectant solution into the soil by being inhaled from the drug tank and sent to the injection part. At the same time, the chemical spraying device is driven and the disinfectant granules are sprayed around the soil intake port of the soil cover device, and the soil cover conveyor device takes in the soil containing the soil disinfectant granules and conveys it upward and backward, The soil is dropped to both sides of the mulch film coated by the coating device and the both sides are pressed.
