DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mulching film stripping and collecting apparatus, and more particularly to a novel apparatus for stripping a mulching film laid in a field and collecting it in a roll.

[0002]

2. Description of the Related Art Mulching refers to a treatment means for covering a soil surface in a field or the like with straw or a plastic film. By performing the mulching treatment, evaporation of water in crops such as vegetables can be suppressed and weeds can be prevented. Breeding can be suppressed, soil disinfection action can be enhanced, and soil jumping can be prevented. In particular, the plant may be destroyed due to drying or the propagation of weeds from planting to survival of the crops. Therefore, the mulching treatment is performed to prevent such death.

[0003] As an example of the conventional mulching treatment, there is known a method in which a mulching film unwound from a roll is spread all over the surface of soil around a crop and fixed. As another method, thinned wood or bark such as straw, cedar, and cypress are cut to an appropriate length, and then crushed to obtain chips. Means for covering the cells by laying them down are also known, but in the case of a field or the like, it is customary to use a mulching film such as polyethylene from the viewpoint of work efficiency.

By performing such mulching treatment, an effect of preventing runoff of topsoil, an effect of suppressing evaporation of water from soil, an effect of suppressing weeds, an effect of disinfecting soil, and an effect of preventing soil from jumping up are obtained. It is possible to prevent crop dying caused by breeding.

[0005]

In the mulching process using the mulching film unwound from the roll, there is a problem in treating the mulching film after use. In the past, manual winding or open burning was mainly performed at the site, but manual winding requires a lot of work, and dioxin is generated from plastics such as polyethylene in open burning. There is a problem that the surrounding environment may deteriorate.

Further, when covering the soil surface with a mulching film unwound from a roll, it is common practice to apply an appropriate amount of earth and sand to the upper surface of the mulching film in order to prevent the mulching film from being blown off by wind or the like. Therefore, earth and sand will be caught in the mulching film at the time of manual winding and collecting,
There is a problem that the weight of the collected material increases, and a large amount of water droplets adhere to the inside of the mulching film, so that the manual winding and collecting operation tends to be a heavy labor.

Therefore, the present invention provides a method for winding a mulching film.
Improved winding drum as a core
Easily remove only the take-up drum from the inside of the
Reuse it so that it can be wiped out and save money
It is intended to be able to reduce.

[0008]

According to the present invention, in order to achieve the above object, a mulching film for covering a soil surface is sequentially rolled on a winding drum wound around a rotating shaft. In the recovery device, a winding drum is used to wind a mulching film by winding a predetermined number of small pieces interconnected as a take-up drum onto a rotating shaft, leaving a gap, and forming a flat plate. A mulching film peeling and collecting device in which the take- up drum is folded inward from the gap when the take-up drum is detached from the rotating shaft after completion of the take-up.
And a structure in which, when the mulching film is removed from the rotating shaft after the winding, the winding drum is folded inward from the gap so as to be able to be removed from the roll-shaped mulching film.

[0017] Stripping and recovery of such a mulching film
According to the device, after the end of the winding of the mulching film
When detached from the rotating shaft, the winding drum itself has a reduced cross-sectional area due to a change in the degree of bending and the gap of the winding drum, so that the winding drum itself is folded inward from the gap and the roll-shaped mulching film is removed. Since the take-up drum can be removed from the inside of the mulching film, only the roll-shaped mulching film can be obtained.

The operation of the mulching film peeling and collecting apparatus having the above configuration will be described below. As described above, the soil surface of the field or the like is covered with a mulching film made of plastic unwound from a roll to suppress the evaporation of water and suppress the growth of weeds in crop cultivation, and enhance the disinfecting action and the rooting action during planting. Cultivate crops such as vegetables. Then, after harvesting the crop, the stripping and collecting apparatus according to the present invention is set on the terminal of the mulching film.

In advance, on the rotating shaft 14 of the stripping and collecting device,
A winding drum 17 bent into a substantially polygonal cylindrical shape by the hinges 21 and 21 is mounted, and the rotation shaft 14 and the rotation bearings 13 and 13 and the ring 16 and Lock 16 Thereby, the rotating shaft 14, the rotating bearings 13, 13, the ring 16,
The take-up drum 16, the take-up drum 17 and the like are assembled in the state shown in FIGS. 1 and 2, and the rotational driving force of the engine 11 is smoothly transmitted to the rotary shaft 14.

First, as a preparatory work, a worker manually grasps a terminal portion of the mulching film from the soil surface,
The mulching film 31 is passed between the guide bars 30 and 30 as shown by a broken line B in FIG.
Then, the mulching film 31 is guided to the take-up drum 17 and then partially wound around the take-up drum 17.

After the preparation work is completed, the engine 11 arranged on the upper part of the engine support member 10 is started.
Then, the rotational driving force of the engine 11 is transmitted from the speed reducer 11a to the rotary shaft 14, and the rotary shaft 14 and the rotary bearing 1
3, 13 and rings 16, 16 rotate simultaneously. As a result, first, the width of the mulching film 31 is regulated by the guide bars 30, 30 to be substantially the same as the length between the rings 16, 16, and at the same time, the rotational driving force of the engine 11 is transmitted from the gear 26 to the chain 26a, the gear 27, the sprocket. 27a, and transmitted to the sprocket 28 via the chain 29, the support rod 25a pivotally supported by the bearing 24 rotates. The rotation of the support rod 25a is transmitted to the support rods 25b, 25c via the connection rods 25d, 25d, and the vibrator 25 is driven to rotate.

After the deposits such as earth and sand which have adhered to the surface of the mulching film 31 fall down due to the vibration accompanying the rotation of the vibrator 25, the mulching film 31
Are sequentially wound in a roll shape on the winding drum 17. As described above, when covering the mulching film 31 unwound from the roll on the surface of the soil, it is usual to apply an appropriate amount of earth and sand to the upper surface so that the mulching film 31 is not blown off by wind or the like. When the film 31 is collected, the mulching film 31
It is conceivable that the
The earth and sand can be reliably dropped from the mulching film 31 by the vibration accompanying the rotation of 5.

The pair of right and left rear wheels 7, 7 rotatably supported by the wheel support members 5, 5 by the reaction force torque when the mulching film 31 is wound around the take-up drum 17 in the form of a roll. The front wheels 9, 9 start rotating, and as a result, the stripping and collecting apparatus itself runs along the mulching film 31. That is, even if no drive source is connected to the rear wheels 7, 7 and the front wheels 9, 9, the mulching film 3
The device itself can be self-propelled only by the reaction torque when the 1 is wound on the winding drum 17.

When the mulching film 31 reaches the end portion of the mulching film 31 laid on the soil surface by the self-propelled operation of the stripping and collecting device, the reaction force torque when the mulching film 31 is wound is eliminated. The running state also stops. Then, the operator grips the handles 1a, 1a attached to the rear R side end surface of the gantry 1 to perform the turning operation of the stripping and collecting device, and performs the same operation again to transfer the mulching film 31 to the winding drum 17. Repeat the winding operation.

The rods 3, 3 inserted into the cylinders 2, 2 and the rods inserted into the cylinders 4, 4 are expanded and contracted in the vehicle width direction according to the shape and size of the mulching film 31 during operation. By changing the positions of the wheel support members 5 and 5 fixed to the distal ends of the rods, the length of the rear wheels 7 and 7 and the front wheels 9 and 9 in the vehicle width direction can be freely adjusted.

After a certain amount of the mulching film 31 is wound around the winding drum 17 in this way, the roll-shaped mulching film 31 is collected. This recovery operation is performed by first operating the operating rod 1 of the bearing 15 supported on the side of the gantry 1.
By opening 5a outward, the fitting state of the other end of the rotating shaft 14 fitted to the bearing 15 is released, and the fitting state of the one end of the rotating shaft 14 is changed. By releasing, the mulching film 31 wound up in a roll shape is lowered from the gantry 1 to the ground integrally with the rings 16, 16 and the winding drum 17 and the rotating shaft 14.

Next, by operating the handles 19, 19 in the direction A, the lock pins 18, 18 are released, and the left and right rings 16, 16 are removed. Thereafter, the rotating shaft 14 is pulled out from the inside of the winding drum 17. By this operation, only the take-up drum 17 and the mulching film 31 wound around the take-up drum 17 from the stripping and collecting device remain.

Next, an operation of taking out the winding drum 17 remaining in the mulching film 31 is performed. The winding drum 17 can be developed in a flat plate shape, for example, a predetermined number of small pieces are connected to form a substantially polygonal cross section, and more specifically, a plurality of metal pieces 20 are hinged 21 and 21. The hinges 21 and 21 are connected by using the hinges 21 and 21 and have a substantially polygonal cross-section with a gap 22 provided in a part thereof. By changing the gap 22, the metal pieces 20, 20 are folded inward when the metal pieces 20, 20 are removed from the rotary shaft 14 after the winding is completed, so that the thickness of the winding drum 17 itself, that is, the cross-sectional area can be reduced. The winding drum 17 can be easily pulled out from the inside of the mulching film 31.
Therefore, at the end of the operation, only the roll-shaped mulching film 31 is obtained.

[0040]

As described in detail above, according to the mulching film stripping and collecting apparatus of the present invention,
At the time of work, a worker manually grasps the terminal portion of the mulching film from the soil surface and passes it between the guide bars, and if a vibrator is provided, passes over the vibrator and guides it to the winding drum to partially wind it. The mulching film can be sequentially wound in a roll shape on the winding drum while the stripping and collecting device is running by simply performing an operation of attaching and driving the drive source. In addition, by disposing the vibrator, it is possible to drop off deposits such as earth and sand adhering to the surface of the mulching film due to vibrations caused by the rotation of the vibrator and then wind the mulch film on the winding drum. There is no increase in the weight of the recovered material due to being caught in the film.

Since the stripping and collecting apparatus according to the present invention runs on its own, and when it reaches the terminal of the laid mulching film, the self-running state is automatically stopped. Therefore, the same operation can be repeated after turning the device, so that the burden on the operator is reduced, and even if a large amount of water droplets adhere to the inside of the mulching film, it is possible to perform manual winding and collecting work. There is no danger of heavy labor.

After a certain amount of the mulching film has been wound around the winding drum, the end of the rotating shaft is released and the lock between the ring and the rotating bearing and the rotating shaft is released by operating the handle. After removing the ring and rotating bearing from the rotating shaft, and further removing the rotating shaft from the inside of the winding drum, the winding drum itself can be reduced in thickness to take out the winding drum from inside the mulching film. At the end of the operation, only a roll-shaped mulching film can be obtained. In particular, since there is no need for open burning as in the prior art, there is no fear that dioxins will be generated from plastics such as polyethylene, and this is also effective in the area of environmental purification.

Therefore, according to the present invention, a large amount of labor is not required for the winding process of the mulching film, and there is no fear that the environment such as the generation of dioxins may be deteriorated. It is possible to provide a stripping and collecting device that does not have any problem.
