Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil disinfecting machine in which a soil disinfectant is sprayed and agitated in cultivated soil, and disinfectant spraying devices, cultivating devices and the like are arranged in front of and behind a tractor body.

[0002]

When a soil disinfectant consisting of half the granules is sprayed on the soil immediately before being cultivated by the rotary tiller, these powders / granules having a low specific gravity are floated up during the tilling action. Difficult to stir deeply and difficult to effectively disinfect.

[0003]

According to the present invention, a disinfectant spraying device 2 for spraying a soil disinfectant is provided on the front side of a tractor vehicle body 1, and a soil surface on which the soil disinfectant is sprayed is provided on the rear side. The soil disinfecting machine is configured by arranging a rotary tilling device 3 for stirring and a squeezing roll 4 for squeezing the soil surface after this tilling.

[0004]

When the soil disinfectant is sprayed while the tractor car body 1 is running, the disinfectant is sprayed by the spraying device 2 on the front side of the car body 1. The sprayed disinfectant is trampled onto the soil surface by the tractor wheels. While cultivating the soil surface in such a state by the rotary cultivator 3, the disinfectant is stirred into the cultivated soil, and the surface of the cultivated soil is crushed by the crushing roll 4.

As described above, since the soil disinfectant powder and granules are sprayed on the front side of the tractor vehicle body 1, some of them are stepped on by the wheels of the tractor and pressed against the soil surface. When cultivated in, the amount of the disinfectant separated from the soil is small, the effect of stirring the disinfectant and the soil is good, and the mixture is deeply stirred, and immediately after this stirring, the pressure roller 4 presses the soil surface. Since it is hardened, the disinfection effect can be improved.

The soil surface is cultivated to a certain width in conjunction with. Reference numeral 18 is a flat plate provided on the rear side of the tilling claw 15 to flatten the surface of the tilling soil.

Grooving disk 1 for forming grooves along the left and right ends of the surface of the tilled soil at the rear side of the rotary tiller.
9, the left and right groove cutting disks 19 are moved downward to alternately form grooves, and the groove forming disk 19 on the non-groove side can be rotated upward to switch to the non-operating position.
The crushing roll 4 crushes the cultivated soil surface leveled by the leveling plate 18 on the rear side thereof over the entire width.

The multi-film laying device 10 includes a film reel 21 which rotatably supports a multi-film 20 having a constant width in a rolled state, and a guide which guides the multi-film 20 to the rear lower part to cover and guide it to the soil surface. A roll 22, a pressing ring 23 made of sponge rubber that presses the left and right sides of the covered multi-film 20 into the groove formed by the groove cutting disk 19, and the multi-film 20 pressed by the pressing ring 23. It is composed of a soil-covering disc 24 and the like for covering and fixing the soil on the upper surface of the side end of A pressing roll 25 is provided on the rear side of the soil cover disk 24, and only the soil cover side is moved downward to press the soil cover to fix the side edge of the mulch film 20 to the soil surface. The pressing roll 25 on the side not covered with soil can be raised to the non-pressing position.

By propelling the vehicle body 1, the disinfectant A is sprayed by the disinfectant spraying device 2, and at the same time, tillage by the rotary tiller 3, crushing by the crushing roll 4, and mulching film 20 by the mulching film laying device 10 are carried out. Let's lay down at the same time. Since the disinfectant A is sprayed on the front side of the vehicle body 1, a part of the disinfectant A is stepped on by the front wheels 6 and the rear wheels 7 and the like, and is cultivated by the rotation of the cultivating claws 15 of the rotary cultivating device 3 and stirred in the soil. To be done. For this reason, the soil disinfectant A has a good stirring effect in the soil and is mixed in a deep layer.

Immediately after the stirring, the compression roll 4
Since the surface of the cultivated soil is suppressed by this, the disinfectant A can be stabilized, and the disinfecting effect is hard to escape to the outside air. or,
As shown in the figure, by covering the soil surface immediately after spraying the disinfectant with the mulch film 20, the soil disinfecting effect can be maintained for a longer period of time. In FIG. 3, the difference from the above example is that the front side of the tractor body 1 does not have a disinfectant spraying device for spraying soil disinfectant, and the rear side of the rotary tiller 3 has
