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 capable of disinfecting soil even in a field after ridge formation.

[0002]

2. Description of the Related Art Conventionally, when performing soil disinfection work using a management machine, a handle of the management machine is turned forward, and a battery or a pump is attached to a front portion of the management machine, and a hitch is provided at a rear portion of the management machine. Attach a mounting frame, attach a plurality of disinfecting claws for disinfection, a crushing wheel, a chemical solution tank, etc. to the frame, and proceed while inserting the lower part of the plurality of injecting claws into the soil to inject a chemical solution and disinfect the soil. Techniques for moving are known. For example, this is the technique disclosed in Japanese Utility Model Laid-Open No. 2-100473.

[0003]

However, in the prior art, since a plurality of devices are separately mounted in front and rear, it takes time to mount the devices. In addition, because the pump is mounted on the front part, the space for workers who handle with the handle is small, and the balance after mounting is poor, so it is difficult to arrange the aircraft at the time of turning etc. Was sometimes In addition, in the usual soil disinfection work using the management machine, the soil is disinfected after tilling without ridges and then performing the soil disinfection work on a flat ground, so that the disinfection work cannot be performed after the ridges. If soil disinfection work is forcibly performed after erecting in the conventional state, tire marks are left, and these tire marks have made it impossible to plant crops due to treading pressure or broken the ridges.

[0004]

The present invention uses the following means in order to solve the above problems. That is, the upper and lower two mounting frames are mounted on the hitch provided at the rear of the management machine, the chemical tank, the pump and the motor for driving the pump are disposed on the upper mounting frame, and the injection claws are disposed on the lower mounting frame. In addition, a traveling wheel is provided on the axle of the management machine so as to be adjustable in the left-right position, and the traveling wheel is a large-diameter wheel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems and means to be solved by the present invention are as described above. Next, embodiments of the present invention will be described. FIG. 1 is a side view of a management machine having a soil disinfecting machine mounted on a rear portion, FIG. 2 is a rear view of the soil disinfecting machine, and FIG. 3 is a rear view showing a tread adjustment configuration of the management machine having the soil disinfecting machine mounted thereon.

Referring to FIGS. 1 and 2, an overall configuration in which a soil disinfecting machine 2 is mounted at the rear of the management machine 1 will be described. In the management machine 1, an engine 29 is mounted on an engine base 26, a fuel tank 27 is mounted on the engine 29, and power is transmitted from the engine 29 to a transmission case 22 via a transmission case 25 on a side portion. The axle 23 suspended under the transmission case 22 is driven to drive the traveling wheels 2.
4 and 24 are driven. The running wheel 24 is configured to have a large diameter so that the axle 23 can pass above the ridge,
The ridges are prevented from breaking down, and the width of the running wheel 24 is reduced so that the running wheels 24 do not enter the grooves between the ridges and break the slopes of the ridges. A handle base 21 is provided on an upper portion of the transmission case 22, and a handle 20 is provided on the handle base 21 so as to be rotatable in front, rear, left and right directions. Further, a hitch 28 protrudes rearward from the transmission case 22, the soil disinfecting machine 2 is mounted on the hitch 28, and the handle 20 is moved forward (engine 29).
Side) to perform a disinfection operation.

As shown in FIG. 3, one ends of polygonal axles 55, 55 are externally fitted to both ends of the axle 23,
