Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl for protecting vegetables and the like from outside air in agricultural work, and a net winding tool for protecting fruits and the like from the wind during a typhoon.

[0002]

2. Description of the Related Art Conventionally, agricultural vinyls and protection nets have been made of cylindrical bodies.
Although it is sold in a wound state, as shown in FIG. 2A, a cut is made in a paper cylinder 9 and the cut portion is fixed to a rotating portion of the electric motor. 8 to 9
, And the cylindrical body 9 is rotated by the electric motor 7 to be used for winding and unwinding vinyl and the like.

However, if the paper cylinder 9 is provided with a cut portion and is wound up and unwound, a gap (a) is formed between the cylinder and the rotary fitting, and as a result, the cylinder 9 itself is formed. However, there is a drawback that the film cannot be wound evenly due to the elliptical movement, and there is a problem that it is not possible to stretch the vinyl at a predetermined position when reused.

[0004]

In view of the above, there is provided a structure for holding a winding machine made of vinyl or the like in which the winding cylinder does not move in an elliptical manner, and in which the trouble of providing a cut portion in the paper cylinder is omitted. That is.

[0005]

Means for Solving the Problems The inventor has thought about how to solve the above-mentioned problems, repeated experiments and prototypes, and as a result, has finally completed the present invention. The structure for holding a winder such as vinyl according to the present invention has solved the problem and is as follows.

[0006] A support portion 2, a holding portion 1 rotatable about the support portion 2 and a fixing portion 3 for fixing both ends of the support portion.
And a fixing portion fixed to a driving portion of the electric motor 7. On the other hand, a holding portion 4 which is moved in the horizontal direction by a variable mechanism portion 5 is provided, and a cylindrical body 9 is provided between the holding portion 1 and the holding portion 4. This is a holding structure of a winding machine that can hold and unwind from the cylindrical body.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be illustratively described in detail below with reference to the drawings. However, the configuration method, configuration device, configuration contents, dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not limited to the scope of the present invention unless otherwise specified. It is not intended to be limited to only the above, but merely an explanation example.

[0008] Agricultural vinyl protects vegetables and the like from the cold in winter and is sold by being wound around a paper cylinder 9 and is more expensive (thicker and larger in size than ordinary vinyl). Is long), so reuse it several times (3-4 times). In addition, the protection net covers vegetables, fruits, and flowers from strong winds and protects them from above.When forecasting strong winds such as typhoons,
Use as many times as necessary. Therefore, there is a background that each farmer devised a machine capable of winding and winding the vinyl / protection net wound around the cylinder many times.

The holding portion 1 is elastic (rubber, plastic)
And a support member 2 is provided in the substantially hollow portion so that the holding portion 1 is rotatable around the support portion 2. Further, both ends of the support portion 2 are provided. Are fixed by the fixing portion 3. In addition, by fixing the rotating part of the electric motor 7 and the fixing part 3 with (bolts and nuts), the fixing part 3, the supporting part 2, and the holding part 1 rotate in the same direction.

A screw rod 51 is provided in a screw hole of the fixing bracket 52.
And a rotatable holding portion 4 is attached to the end of the screw bar.
And an arm 6 provided at the other end, and is constituted by a variable mechanism section 5 having a structure in which the holding section 4 moves in the horizontal direction by rotating the arm 6. Furthermore, the structure of the holding portion 4 is the same as the structure of the holding portion 1.
It is also an example of a preferred embodiment to use the support portion 2 and the rotating holding portion 1.

As a method of use, the interval between the holding portion 1 and the holding portion 4 is adjusted to a required interval by the arm 6, the paper cylinder 9 is brought into contact with the holding portion 4, and the other end is held at the holding portion. The arm 6 is used to mount it using one rotation power and to hold it more strongly.
Is manually rotated, the variable mechanism unit 5 operates, the holding unit 4 moves in the horizontal direction, and the paper cylinder 9 is held in the holding unit 1.
And can be fixed by the holding portion 4.

Next, the tip of the vinyl / protection net is fixed to a paper cylinder 9 and power is supplied to an electric motor 7 (with a built-in inverter whose rotation speed can be varied), thereby forming a paper cylinder. Rotates slowly, so the cylinder 9
Since the rotation is performed while the protection net is wound, the electric motor is stopped while being wound around the cylinder 9, and the arm 6 is manually rotated in the direction of removing the cylinder to remove the cylinder 9 from the holding portions 1, 4. Work can be completed.

When the vinyl / protection net is to be reused, the paper-made cylinder 9 is applied to the holding unit 4 with the holding body 1 and the holding unit 4 at a required distance from each other. And the other end is attached using the rotating power of the holding unit 1, the paper cylinder 9 is held between the holding unit 1 and the holding unit 4, and the arm 6 is held so that there is no gap between the holding. Rotate to fix the cylinder,
By supplying electric power that rotates in the reverse rotation direction to the electric motor 7, the vinyl / protection net is unwound to cover and protect vegetables, fruits, and flowers from above.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments at all, and may be implemented in various modes without departing from the gist of the present invention. Of course.

[0015]

According to the present invention, not only is the work step of inserting a cut portion into a paper cylinder and mounting it cut off, but also the eccentricity of the cylinder is automatically achieved by the pivoting of the holding portion about the support portion. So that the elliptical motion of the winding cylinder is corrected to a circular motion, and the cylinder is rotated to wrap vinyl and a protective net.
Even if the unwinding operation is repeated, vinyl wrapped around the cylinder
There is no bias in the protection net, and uniform winding can be performed.

In addition, since the winding work of the vinyl and the protective net can be evenly performed, it can be stretched at a predetermined position when reused, so that the workability can be improved and the appearance can be improved. (The state in which the tension is appropriately given) is also improved.
