Abstract

PURPOSE:To constantly keep a soil amount supplied from a hopper to an upper surface of a mulch film by installing a scoop conveyer and return shooter on the hopper holding the soil applied to the upper surface of the covered mulch film. CONSTITUTION:A mulch film 1 is pulled out and laid on a soil surface to cover and a soil A kept in a hopper 3 is laid on the upper surface of the mulch film. A part of a cultivated soil is conveyed to a hopper 3 by a conveyer 4 and an excess soil is returned to the soil surface by a return shooter 5.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mulch film laying device for laying mulch film on a soil surface.

[0002]

2. Description of the Related Art In laying a mulch film, a part of the tilled soil is placed on the upper surface of the mulch film coated on the soil surface in order to reduce peeling due to wind pressure and the like. Although there is a form of stabilization, it is desirable that the amount of soil placed on the upper surface of this mulch film is constant, and in particular, in the form in which this soil is lapped with a film, this need is great.

[0003]

According to the present invention, a film coating device 2 for coating a soil surface while pulling out a mulch film 1 and a hopper 3 for accommodating soil A to be placed on the upper surface of the coated mulch film 1 are provided. A mulch film laying device is provided, which is provided with a conveyor 4 that conveys a part of the tilled soil to the hopper 3, and a return shooter 5 that returns the excessively supplied soil in the hopper 3 to the soil surface.

[0004]

[Advantages of the Invention and Effect of the Invention] The mulched film 1 is pulled out by the film coating device 2 on the surface of the cultivated soil by the traveling of the machine body, and at the same time, a part of the cultivated soil is scooped up by the conveyor 4. Bring it into hopper 3,
The mulch film 1 covered with a shooter or the like is placed on the upper side surface in a constant amount. If the soil supplied to the hopper 3 by the conveyor 4 becomes excessive, it overflows and returns to the soil surface where the mulch film 1 is not laid through the return shooter 5.

In this way, the amount of soil supplied from the hopper 3 to the upper surface of the mulch film 1 can be kept constant in order to keep the soil in an excessive state in the hopper 3 and overflow to the return shooter 5. , Accurate multi-film laying can be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tilling device 7 which is moved up and down by a vertical movement of a lift arm 6 behind a tractor body, and a potter 10 which is connected behind a tilling frame 8 with a tool bar 9 or the like to form a ridge C groove D. A film coating device 12 mounted by a multi-frame 11, a soil mounting device 13 and the like are provided behind the culture device 10.

The film coating device 12 rolls a multi-film 1 having a predetermined width and rotatably supports the multi-film 1 on a reel 14, and the multi-film 1 is pressed down by a pressure-reducing roll 15 while being drawn onto the soil surface. The earth-mounting device 13 is a conveyor 4 which looks into the rear side of the tilling device 7 and scoops up fine soil cultivated by the rotary nail tilling device 7 and conveys it to the upper rear portion. Return shooter 5 having a general structure, a hopper 3 for receiving and containing the soil A conveyed from the conveyor 4, a feeding device 16 for feeding a fixed amount of soil while drivingly rotating the feeding port of the hopper 3, and the feeding device 16. It is composed of a shooter 17 and the like that causes the soil to flow backward.

Soil B discharged from the shooter 17
While wrapping the wrapping film 19 with another wrapping film 19 laid on another reel 18,
A wrapping device 20 to be placed on the upper surface, a rear crushing roller 21 to crush the wrapping soil B from the upper surface, and the like are provided. In the hopper 3, the conveyor 4 is provided on the upper part.
, The return port 22 at the upper end of the return shooter 5 is positioned below the upper end of the conveyor 4 and opened, and the conveyor 4 carries the soil into the hopper 3 as high as possible and surplus soil accumulated. To the return shooter 5. When the return shooter 5 is clogged with soil, it is scraped off in the return stroke of the upper conveyor 4.

The rear shooter 17 for letting down the soil fed by the feeding device 16 is branched at each soil mounting position, but the soil A in the hopper 3 is always spread over the feeding port of each shooter 17. Because of being filled, even if the vehicle body is greatly inclined to one side with the ground or the like, the empty feeding by the feeding device 16 or a part of the shooter 17 is performed.
There is no empty discharge to the mouth.

Reference numeral 23 denotes an opening / closing cover on the upper part of the hopper 3, and 24
Is a grounding roller of the pottery 10. FIGS. 3 and 4 show a film laying device of a full-face multi type that is laid so as to cover the entire surface of the soil. The mulch film 1A laid in the previous process and the mulch film 1B laid in the current process are shown. The side edges of the
Is pressed from above and below by the rollers 25 and 26, and the upper roller 26 is heated by the burner 27, whereby the overlapped portion E is welded and the joint portion F is formed. Lower roller 2
The roller arm 28 is attached to the multi-frame 11 by picking up the side edges of the laid multi-film 1A in the previous step from below. Also, the upper roller 26
The roller arm 29 is pivotally supported 30 on a part of the multi-frame 11 so as to be vertically rotatable, and is springed downward by a spring 31.

In FIG. 5, the upper and lower rollers 26,
In place of 27, sheet metal sliders 32 and 33 are provided, the upper slider 33 is made of a metal having good heat transfer, and has a heating wire 34 on the upper side. The heating by the heating wire 34 causes the multi-films 1A and 1B to be separated from each other. Weld the overlap E. 6-
In FIG. 8, the film coating device 2 is provided with a soil cover disk 35 on the side edge of the coated mulch film 1 on the rear side of the compression roll 15 for placing the soil G thereon. This soil disc 35
Are rotatably supported by disc arms 36 on both left and right sides of the multi-frame 11, and the disc arms 36 can be folded upward against 37.
When using it, lower it to cover the soil.

Further, the multi-frame 11 is provided with a sub-soiler 38 for cutting a groove H in the soil, a pipe 39 for injecting a disinfectant solution along the back surface thereof, a tank 40 for sending the disinfectant solution to the pipe 39, and the like. The disinfecting solution is poured into the soil in the previous step of coating No. 1. 41
Is a wheel of a tractor, 42 is a lower link, 43 is a top link, and 44 is a connecting frame. Multi-film laying work is performed while traveling on the soil surface cultivated in advance by the tiller.

In the first film laying process at the start of the work, when the work is performed with the soil cover discs 35 on the left and right sides being lowered, the soil G is covered on the left and right side edges of the multi-film 1. In the second stroke of the adjacent strip, the soil-covering disc 35 on the adjacent side is raised so as not to be used, and only the soil-covering disc 35 on the opposite side is used. At this time, mulch film 1
The side edges of the film are polymerized, and the adhesive K is applied to one side edge of the mulch film 1 by an adhesive application device separately, and the pressure is applied to the polymerized portion by the pressure roller 15 to bond them. Then, while forming the joint portion 45, the entire surface of the soil is covered with a multi-layered mulch.

In this manner, the multi-film 1 may be joined with an adhesive tape instead of applying the adhesive.
