Description

Exchangeable TORCH EXTENSION HEAD FOR PUNCHING MULCHING VINYL AND MACHINE OF PUNCHING MULCHING VINYL USING TORCH EXTENSION HEAD

The present invention is for forming a hole in mulching vinyl, and more specifically, a replaceable torch extension head capable of forming a hole of a desired size without being affected by wind and forming a hole in the mulching vinyl, and the torch extension head It relates to a mulching vinyl perforation device used.

A ridge is formed for planting seeds or seedlings for growing crops, and the ridge can be vinyl mulched to facilitate temperature and humidity control.

And in order to plant seeds or seedlings in the ridges covered with vinyl mulch, a hole is formed in a part of the vinyl, usually with a knife or a seedling shovel, or with a gas torch.

When using a gas torch, if the heating time is too long or the distance is too close, there are many cases where the mulching vinyl has too large a hole and the effect of mulching is drastically reduced. In addition, if the surrounding wind blows too hard, the gas is often extinguished and there is also the inconvenience of having to ignite it again.

In order to solve this problem, Utility Model Registration No. 20-0470774 discloses a "heat cutting device for the distribution part of mulching vinyl". The thermal cutting device uses a gas flame, but continuously heats a U-shaped touch member, and cuts the vinyl in a U-shape. In this case, there is an advantage of cutting like painting, but if there is a lot of wind around, heat transfer efficiency may decrease, and there is a disadvantage that the vinyl needs to be secondarily wetted or removed.

In addition, Patent Publication No. 10-2019-0069701 discloses "a mulching vinyl perforator using a flame". In the mulching vinyl perforator, a flame is generated using gas, but a flame supply port and a flame outlet are installed on the upper side, a flame holding forest is installed inside to maintain the flame, and a bottom plate is installed on the bottom of the inner cylinder to direct the flame and the vinyl Limit contact.
