Description

[Detailed description of the invention] The present invention relates to a synthetic resin membrane hole puncher for multi-farming.

The present invention relates to an instrument that covers crops grown in fields with a synthetic resin film and makes holes in the synthetic resin film as the crops grow.

Since a thin synthetic resin film is easily melted by heat, a melting hole can be easily formed by applying a heated heating element to the thin synthetic resin film.

This device uses a commercially available portable gas cylinder, and has a hand-held mobile structure that heats a heating element with the flame emitted from the gas cylinder.

However, after conducting various experiments, they discovered that there was a problem with the firepower.

In other words, at the beginning of the work, even if you can do the work as expected,
After a short period of time has elapsed, the heating element is no longer sufficiently heated and no melting holes are formed.

The reason for this is that when the liquefied gas vaporizes, the peripheral wall of the cylinder is cooled to prevent vaporization, and when working in the field, the wind in the field hits the flame, significantly worsening the thermal effect.

Therefore, in the present invention, a gas guide pipe 9 is connected to a gas cylinder 1, a flame fitting 10 that ejects flame downward is attached to the tip of the pipe 9, and the tip of the flame fitting 10 is heated by the flame. In a device in which a heating body 13 is attached and the heating body 13 is brought into contact with a synthetic resin film to form a melting port, the gas cylinder 1 is placed in a container 2 that accommodates the gas cylinder 1 in a state where the gas cylinder 1 is exposed almost entirely. A shoulder strap 3 is attached to the housing body 2, and an inverted plate body 11 and a plate body 12 are provided facing each other between the flame fitting 10 and the heating body 13, and the inverted plate body 11 is A flame swirling chamber 14 is formed between the plate body 12 and the plate body 12, and the plate body 12 is a synthetic resin membrane hole puncher for multi-farming, which is integrally joined to the upper surface of the heating body 13. This prevents these defects.

To explain the embodiment, 1 is a gas cylinder, and the gas cylinder 1 is housed in a liquid container 2 that can be stored in a state where almost all of the gas cylinder is exposed, and a shoulder strap 3 is attached to the basket-like container 2 to carry it. enable.

A cap 4 is attached to the mouth of the gas cylinder 1, and one end of a rubber hose 6 is connected to an ejection tube 5 protruding from the side of the cap 4.
A gripping part 7 is attached to the other end of the rubber hose 6, and a pipe 9 is attached to the other end of the gripping part 7 via an elbow 8.

A flame fitting 10 that ejects flame downward is attached to the end of the pipe 9, a reverse catcher 11 is attached to the lower end of the flame fitting 10, and a dish 12 is installed with a gap at the bottom of the inverted dish 11. They are provided facing each other, and the heating body 13 is integrally joined and attached to the lower part of the dish body 12.

14 is a swirling chamber formed between the plate body 11 and the plate body 12.

Since the present invention has the above-mentioned configuration, the gas cylinder 1 is hung on the shoulder using the shoulder strap 3, the holding part 7 is held, the gas cylinder 1 is carried to the field, and the heated heating element 13 is applied to the upper surface of the synthetic resin film. , the flame ejected from the flame fitting 10 swirls in a swirling chamber 14 between the inverted dish body 11 and the dish body 12;
Since 2 is integrally joined to the heating body 13, it is well heated by the heating body 13, and a melting port can be formed instantly.

Therefore, the gas cylinder 1 of the present invention has a structure in which the container 2 that houses the gas cylinder 1 is used with almost all of the gas cylinder 1 exposed.
It is in contact with outside air at a temperature between 8°C and 8°C.

Therefore, even if the liquefied gas vaporizes and cools the peripheral wall, it is warmed by the warm outside air, so the flame ejected from the flame fitting 10 is maximized to sufficiently heat the heating element 13.

In addition, since the work is carried out in a field, there is always a slight breeze, but in this invention, the flame ejected from the flame fitting 10 is
Since the machine rotates in the rotating chamber 14 between the inverted plate body 11 and the plate body 12, the work can be carried out almost unaffected by wind.

After repeated experiments with the previous example, we found that there was a problem with the heating power, and even though the work could be done as desired at the beginning of the work, after a short period of time, the heating element was not heated enough. , the melting port was no longer formed.

However, in the present invention, a gas guide pipe 9 is connected to the gas cylinder 1, a flame fitting 10 that ejects flame downward is attached to the tip of the pipe 9, and a heating element heated by the flame is attached to the tip of the flame fitting 10. 13 is attached and the heating body 13 is brought into contact with a synthetic resin film to form a melting port, the gas cylinder 1 is housed in a housing body 2 that houses the gas cylinder 1 in a state where it is exposed almost entirely. , the storage body 2 has a shoulder strap 3
is installed between the flame fitting 10 and the heating body 13,
The inverted dish body 1 is provided with an inverted dish body 11 and a dish body 12 facing each other.
A flame swirling chamber 14 is formed between 1 and the plate body 12, and the plate body 12 is integrally joined to the upper surface of the heating body 13 to form a synthetic tree electrode membrane hole puncher for multi-farming. From the following, (a) the gas cylinder 1 of the present invention has a container 2 that houses it.
Since this is a structure in which the gas cylinder 1 is used with almost all exposed, the liquefied gas is constantly passed through the peripheral wall at a temperature of 5°C to 8°C.
C. Therefore, even if the liquefied gas vaporizes and cools the surrounding wall, it will be warmed by the warm outside air, so the flame fitting 1
The heating body 13 is sufficiently heated by increasing the flame ejected from zero to the maximum size.

(b) Since the work is carried out in a field, there is always a slight wind, but since the flame ejected from the flame ejecting fitting 10 swirls in the swirling chamber 14, the influence of the wind is almost unaffected. (c) The plate body 12 Since it is integrally joined to the upper surface of the heating body 13, good heat conduction is achieved.
