Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for laying a multi-film on a whole surface, which is capable of injecting a soil disinfectant into the soil prior to a film laying operation.

[0002]

2. Description of the Related Art The applicant of the present invention has proposed a full-face multi-apparatus that covers the entire field without opening the film. However, until now, a device for injecting a chemical solution onto the entire ridge has been proposed. It doesn't exist. Known documents for disinfecting soil include, for example, the one disclosed in Japanese Utility Model Laid-Open No. 57-203786.

[0003]

SUMMARY OF THE INVENTION According to the above-mentioned publication, a ridge shaping plate and a mulching device are sequentially connected to the rear of a rotary working machine, and the ridge shaping plate and the mulching device are sequentially connected to the lower rear of the rotary case. The disinfecting liquid is jetted from one nozzle provided to disinfect the soil under cultivation. This device has a drawback that the entire length of the entire device becomes long because only the shaping plate and the mulching device are connected in front and rear, and moreover, one nozzle is arranged on the back surface of the rotary case. Due to the structure provided, there is a problem that it is not suitable for soil disinfection of a wide ridge. Further, since the device described in this publication moves the soil inward by the soil gathering wheel to cover the edge of the film with soil, the soil is not sufficiently covered, and the film peels off or gas is removed from the peeled portion. May leak out.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a single conveyor for picking up soil and conveying it upwards, and a lower end of the conveyor which is branched from the upper part of the conveyor to the left and right. comprising a plurality of chute that is, the said conveyor and the chute is configured to Ryakuyama type shape when viewed from the side, multi film formed by providing a film laying device to the lower space of the structure portions in these mountain-shaped In the laying apparatus, a plurality of injection claws that advance into the soil are provided in the soil scooping side of the conveyor in the width direction, and nozzles for spraying a chemical solution are provided along the back of these injection claws for spraying the chemical solution. The film laying device arranged on the rear side of the nozzle is configured to lay the multi-film in a state in which the end of the multi-film laid in the current stage overlaps the end of the multi-film laid in the previous process, Was entirely multi-film laying device, characterized in that a said chute to drop the soil overlapped part of the multi-film laid the film laying device.

Embodiments of the present invention will be described below based on the embodiments shown in the drawings. First, the structure will be described. The tiller 5 is provided behind the pair of left and right wheels 16, 16 (FIG. 3). As shown in FIG. 2, the cultivating devices 1, 1, 1 ... Are provided laterally in the machine frame 7 behind the cultivating device 5, and are symmetric with respect to the center of the pair of wheels 16, 16. A pair of ridges 8 ₂ and 8 ₂ are made.

As shown in FIGS. 2 and 3, a pair of nozzles 2 and 2 are provided from a pair of left and right rotating shafts 18 in the front-rear direction. These nozzles 2 and 2 are shown in FIG.
When viewed from the side, as shown in FIG. 5, the middle part is gently curved downward and is fixed so as to be along the back part of the injection claws 11, 11 which can be earthed. The left nozzles 2 and 2 operate downward with respect to the forward direction a, and the right nozzles 2 and 2 are rotated 90 degrees counterclockwise so as to be stopped.

The outer nozzle 2 of the left-hand side nozzles 2 and 2 is pushed into the ridge 8 ₁ made in the previous step from the side along with the injection claw 11 and pumps 17 (the left-hand side pump is not shown). The chemical liquid discharged from ( ₁ ) is sprayed into the ridge 8 ₁ . Further, the nozzle 2 on the inner side is configured to inject the chemical liquid into the soil in front of the ridge 8 ₂ formed on the left side.

[0008] As shown in FIG. 2, Li was wound multi-film 3 ₂ at a position offset to the left relative to the wheel 16, 16 - Le 12 is provided, the multi-film 3 ₂ of said that from now fed It is hung on the ridges 8 ₁ and the ridges 8 ₂ and the lateral ends of the film 3 ₂ are ridges 8 _1
2 outer trough 9 _1, so that is pressed against the 9 _2.

A single conveyor 15 for transporting a part of the soil cultivated by the tiller 5 upward and obliquely is provided so that its lower end faces the front of the soil tiller 1 and its upper end. In order to distribute the conveyed soil into three, three shooters 14, 14, 14 are collectively provided at one place, and the lower ends of those shooters 14, 14, 14 are left and right.

[0011]

As described above, according to the present invention, there is provided a single conveyor for picking up soil and conveying it upward, and a plurality of shooters branched from the upper portion of the conveyor and having their lower ends distributed in the left-right direction. When viewed from the side, it is configured in a substantially mountain shape, and a film laying device is provided in the lower space part of the portion formed in these mountain shapes, and a pouring claw that advances in the soil on the scooping side of the conveyor in the width direction. Since a plurality of them are provided in each, the length of the entire device can be shortened.

Further, since the nozzle for spraying the chemical liquid is provided along the back part of the injection claw, the resistance of soil is not directly applied to the nozzle during the work, and when the nozzle advances in the soil. As a result, the resistance of the solution is reduced and the chemical solution is smoothly injected into the soil. Furthermore, after the chemical solution is directly sprayed into the soil, the entire surface of the soil is covered with the mulch film, and the soil discharged from the shooter is dropped onto the overlapping parts of both ends of the mulch film to securely hold the mulch film. It is hard to be peeled off, and therefore the entire surface of the soil filled with the chemical solution is completely and surely covered with a mulch film, so that the evaporation of the chemical solution injected into the soil can be suppressed, the gas leakage can be reduced, and the disinfection effect can be enhanced. It is economical because the amount of chemicals can be reduced.
