In Figure 1, Figure 2, Figure 3, top link 13 and lower link 11, 11 of the tractor, is mounted directly to the top portion of the link mast 10 of the front portion of multiple simultaneous soil disinfection machines, multiple simultaneous soil The case where the rotary tilling device is not interposed in the sterilizer is shown. Sub-soilers 7L and 7R are disposed at left and right positions of the top link mast 10, and the sub-soilers 7L and 7R are configured to pass through the passing positions of the tractor tires 19L and 19R. The subsoilers 7L and 7R use the tires 19L and 19R.
The trajectory of R is erased. A plurality of chemical liquid pumps 14 are arranged on a support rod that stands upright after the top link mast 10. Lateral rod 22 at the rear of the chemical pump 14
, A plurality of disinfectant injection claws 9 are supported. The disinfectant injection claw 9 is inclined forward. In this embodiment, gauge wheels 1L and 1R are arranged on the left and right sides of the disinfectant injecting claw 9 in which six are arranged. Therefore, the antiseptic injection claw 9 and the gauge rings 1L and 1R are in an overlapping state in a side view.

The soil leveling plate 2 is arranged at the rear of the row of the disinfectant injection claw 9 and the gauge wheels 1L and 1R. Since the disinfectant injection claw 9 is inclined forward as described above, the soil leveling plate 2 is arranged so as to extend forward to the extent that there is no possibility of interference, but it interferes with the gauge wheels 1L and 1R. It is.
Nevertheless, a portion where the rear portions of the gauge wheels 1L and 1R interfere with the soil leveling plate 2 is formed as a cutout portion 2a so that the overall arrangement is not as long as possible. A chemical solution tank 12 is arranged at a position above the soil leveling plate 2, and the chemical solution in the chemical solution tank 12 is sucked by a chemical solution pump 14, discharged with an applied pressure, from the tip of the disinfectant injection nail 9. Inject into the soil. Chemical tank 12 and chemical pump 14
A preliminary film table 8.8, on which the film cylinder 3 can be installed in the horizontal direction, is provided upright.

The front and rear rods 18 protrude rearward from the left and right ends of the horizontal rod 22 supporting the disinfectant injection claw 9 and the gauge wheels 1L and 1R, and have a groove extending downward from the rear of the front and rear rods 18. The cutting disk 6 is supported by projection. The film cylinder 3 is inserted into the groove opened in the soil by the grooved disks 6L and 6R.
Embed the left and right ends. Then, while being pressed by the film pressing wheel 4, the soil is covered with the covering disk 5, and the multi-film F is pressed so as not to fly by the wind. The portions of the film pressing wheel 4 and the covering disk 5 are supported by a release support rod 23 which can be released from rotating upward. The release support rod 23 is pivotally supported at the rear end of the front and rear rods 18. The film cylinder 3 with the multi-film F wound thereon is supported between the rear portions of the grooved disks 6.

Referring to FIG. 5, a description will be given of a case where the multi-simultaneous soil disinfecting machine is directly mounted on a work machine mounting mechanism of a tractor. In this case, the upper square pipe portion of the subsoiler 7 is inserted and fixed into the left and right square holes of the mounting frame 31 formed by the square pipe. A main frame 33 projects leftward and rightward from the mounting frame 31, and a bracket 36 of a reinforcing mast 34 is provided on the main frame 33. A reinforcing mast 34 is provided between the bracket 36 and the top of the top link mast 10.

The rear end of 1.11 is configured to be pivotally supported. When a multi-simultaneous soil disinfecting machine is directly mounted on the tractor work machine mounting mechanism, the trajectory of the tire 19 of the tractor needs to be erased. Therefore, the subsoiler 7 is disposed behind the trajectory of the tire 19. However, when the rotary tilling device is arranged between the tractor and the multi-simultaneous soil disinfecting machine, the rotary tilling device itself tillies the rear of the tire 19, so that there is no need to provide the subsoiler 7.

FIG. 4 shows an embodiment in which a rotary tilling device is mounted at the rear of the tractor, and a multi-simultaneous soil disinfecting machine can be mounted at the rear end of a depth beam 37 supporting a depth wheel of the rotary tilling device. It is shown. Since the rear end of the depth beam 37 forms a U-shaped mounting portion, a rotary hitch 38 formed by a square pipe that can be inserted into the U-shape is required. Since the rotary hitch 38 also needs to be mountable on the mounting frame 31, a portion of the insertion square pipe 39 which can be mounted on the portion where the subsoilers 7 are mounted on both ends of the mounting frame 31 is configured. The insertion angle pipe 39 and the rotary hitch 38 constitute a hitch. In the case where the top link mast 10 is attached to the rear part of the rotary tilling apparatus in this manner, the top link mast 10 is removed and the reinforcing mast 34 is also removed, so that neither the bracket 36 nor the lower link pin bracket 35 is used. The same point is attached to the main frame 33, to which the horizontal rod 22, which is a main part of the multiple simultaneous soil disinfection machine, is attached.

Next, FIG. 6 will be described. A test pin 30 projects forward from the front and rear rods 18 on which the disc 6 and the soil leveling plate 2 are mounted.
At 0, the upper mounting hole of the disinfectant injection claw 9 can be inserted.
