Description

Fire Weeder {Torch for weeds removal}

The present invention relates to a weed removing igniter, and more particularly, to a weed removal igniter which is easy to carry and move and which can easily adjust the radiation width of the flame for removing the weeds.

It is advantageous to cultivate these weeds because unnecessary weeds grow on cropland or farmland where crops are grown, which hinders the growth of crops and may impede human movement.

Therefore, conventionally, to remove weeds, weeds were removed by diluting a highly toxic liquid herbicide, which is a chemical compound, with water and spraying it with soil using a sprayer.

However, conventional herbicides are all very fatal to humans and crops, and when they touch the human body, they cause severe damage to the skin and, in severe cases, even threaten life. In addition, crops rot or dry when they touch the crops, and herbicides sprayed on the soil penetrate into the soil and become the main culprit causing soil degradation and serious pollution of the natural environment.

Therefore, in the case of herbicidal work using liquid herbicides as described above, wear protective equipment to prevent the contact of the herbicide liquid to the human body, and in order to prevent the herbicide liquid from contacting the crop when sprayed on the crop There was an inconvenience in that we need to cover or cover with a separate protective equipment weeding work.

However, wearing protective equipment and installing protective equipment is very cumbersome and inconvenient, so we often perform weeding without additional protective equipment or protective equipment, which causes liquid herbicides to touch the skin and damage skin or produce crops. It has been damaged so much, and it is impossible to enter immediately after weeding, and the weeds dried by herbicide are dried for a long time, so they do not look very good, until the effectiveness of the herbicide disappears. There was a problem that the waste of time is severe because it can not do a special work or farming.

In order to solve this problem, Korean Utility Model Registration No. 20-0214117 discloses a heat weeding machine that can remove weeds using fire.

The thermal weeding machine can remove other weeds by using fire to perform other operations for crop cultivation immediately after weeding, and also have the advantage of exterminating pests inhabiting the weeds.

However, since the conventional thermal weeding machine cannot be separated, it is not easy to store and move, and there is a problem in that the area where the flame is radiated cannot be freely adjusted.

3 to 5, the flame radiator 30 is for burning weeds by radiating a flame through the gas supplied from the gas supply unit 20, and the vertical member 31, the horizontal member 38, and the igniter. 48 and a safety cover 52 are provided.

The vertical member 31 has a gripping tube 32, one end of which is in communication with the connecting hose 23, and two extension tubes 33 coupled to the lower end of the gripping tube 32.

The gripper 32 has a handle 34 on the outer circumferential surface that is easy for the user to grip by hand so that the user can adjust the radial direction of the flame through the gripper 32 without slipping. And one side of the gripping pipe 32 is provided with a control valve 35 for controlling the movement of the gas flowing through the connection hose 23, the control valve 35 to temporarily extinguish the flame during the weeding operation or It is used to control the injection amount of.

When the weeding operation is interrupted for a long time, it is preferable to cut off the gas supply using the main valve 22 of FIG. 1, but when the flame is temporarily removed, the wearing part 10 is removed to open and close the main valve 22. And since it is cumbersome to wear again, it is possible to temporarily block the supply of gas using the control valve (35). In addition, the intensity of the flame may be adjusted by adjusting the supply amount of gas through the control valve 35. In addition, the holding tube 32 is provided with a switch 36 for igniting the igniter 48 described later, and a battery 37 for applying power to the igniter 48 in accordance with the signal of the switch 36.

Extension tube 33 is coupled to the lower end of the holding tube 32 to extend the length of the vertical member 31. Since the extension tube 33 has a predetermined unit length, by adjusting the number of extension tubes 33 the vertical member The length of 31 can be varied. Since the extension tube 33 is screwed with the holding tube 32 to be coupled and detachable, it can be easily moved and stored by separating the extension tube 33 and the holding tube 32 from each other during movement or storage.

The horizontal member 38 is coupled to the lower end of the vertical member 31 and extends in a direction crossing the extending direction of the vertical member 31 to radiate a flame extending in the horizontal direction toward the weeds.

The horizontal member 38 includes a fixed tube 39 coupled to the vertical member 31 and a first sliding tube 43 and a first sliding tube 43 coupled to each other so as to be pulled in and pulled out from both sides of the fixed tube 39. A second sliding tube 47 is coupled to the pull-out and withdrawal.

The fixed tube 39 has an inner space through which gas can move, and a first injection hole 40 through which gas can be injected to the outside is formed. Guide protrusions 41 protruding inward in the longitudinal direction are formed on the inner circumferential surface of the fixed tube 39, and ball flanges 42 protruding inwardly are provided on both inner surfaces of the fixed tube 39.

The first sliding tube 43 is drawn and drawn into the inside of the fixed tube 39 along the longitudinal direction of the fixed tube 39 to adjust the radiation width of the flame, the guide projection 41 of the fixed tube 39 on the outer peripheral surface A corresponding guide groove 44 is formed, and a second injection hole 45 through which gas is injected is provided at a lower portion thereof. In addition, the outer circumferential surface of the first sliding tube 43 is formed to be spaced apart so that the inlet grooves 53 extend along the moving direction of the first sliding tube 43 at a point of contact with the ball flanger 42 of the fixed tube 39. Although not shown, a ball flanger (not shown) for fixing the second sliding tube 47 to the first sliding tube 43 is also provided on the inner side surface of the first sliding tube 43.

In addition, at one end of the first sliding tube 43 positioned inside the fixed tube 39, a sealing member 46 is provided on the outer circumferential surface and in contact with the inner circumferential surface of the fixed tube 39, and the sealing member 46 is fixed tube 39. Gas is prevented from leaking through the spaced space between the inner circumferential surface of the) and the outer circumferential surface of the first sliding tube 43.

Fixing of the first sliding tube 43 is made by the combination of the ball flanger 42 and the inlet groove 53, after sliding the first sliding tube 43 to the inlet or withdrawal with respect to the fixed tube (39) When the movement of the first sliding tube 43 is stopped, the ball plunger 42 of the fixed tube 39 is introduced into the corresponding inlet groove 53 of the first sliding tube 43 adjacent to the first sliding tube 43. It is fixed with respect to the fixing tube (39). Since the first sliding tube 43 is pressed by the ball flanger 42, the first sliding tube 43 is not drawn into or drawn out from the fixed tube 39 unless an external force is applied.

In addition, since the guide groove 44 of the first sliding tube 43 is guided by the guide protrusion 41 of the fixed tube 39, since the first sliding tube 43 does not rotate, the second injection hole 45 is disposed. The injection direction of the gas is always the same as the injection direction of the gas through the first injection hole (40) of the fixed tube (39).

In addition, since the spaced intervals of the inlet grooves 53 correspond to the spaced intervals of the first injection hole 40 and the second injection hole 45, even when the first sliding tube 43 is drawn into the fixed tube 39, the gas is separated. Is easily injected to the outside through the second injection hole 45 and the first injection hole (40).

The second sliding tube 47 has an outer diameter corresponding to the inner diameter of the second sliding hole so as to be introduced into the first sliding tube 43. Since the second sliding tube 47 has the same technical configuration as that of the first sliding tube 43, only the size of the outer diameter is different, a detailed description thereof will be omitted.

When the first and second sliding pipes 43 and 47 are introduced into the fixed pipe 39, the flame is emitted only from the lower part of the fixed pipe 39, but the first and second sliding pipes 43 and 47 are moved to the fixed pipe 39. Withdrawal from the fixed tube 39 can extend the radiation width of the flame, so that it is easy to burn a large area of weeds.

The igniter 48 is installed in the fixed tube 39 to ignite the gas injected through the first injection hole 40. When the switch 36 installed in the holding tube 32 is pressed, the power of the battery 37 is turned off. Sparks are generated in the igniter 48 through. The spark ignites the gas injected through the first injection hole 40, and the gases injected from the adjacent injection holes are also ignited in turn.

Since the igniter 48 should be installed to be adjacent to the first injection hole 40 of the fixed tube 39 in which the flame is radiated, it is preferable that the igniter 48 is made of a heat resistant material. In addition, the wire cable 49 connecting the igniter 48 and the switch 36 to the first and second connectors 50 and 51 to facilitate separation when the horizontal member 38 and the vertical member 31 are separated. Are combined by Accordingly, when the vertical member 31 and the horizontal member 38 are separated and moved, the first and second connectors 50 and 51 may be separated and moved separately.

The horizontal member 38 is also provided with a safety cover 52. The safety cover 52 is installed between the fixed tube 39 and the first and second sliding tubes 43 and 47 and the vertical member 31 so that when the flame is emitted, the flame is radiated toward the user or outside the ground. This is to prevent radiation.

If the wind blows against the user while radiating the flame to remove the weeds, the flame may be burned toward the user, and there is a risk of burns, and the surrounding crops or facilities may spread. Therefore, the safety cover 52 limits the radial direction of the flame to a predetermined angle toward the ground so that the radiation of the flame can be made safely. Safety cover 52 is preferably made of a heat-resistant agent such as ceramics, asbestos because it is in contact with the flame to limit the radial direction.

Since the horizontal member 38 expands the radiation width of the flame in the horizontal direction, it is possible to quickly burn a large area of weeds. However, if the flame is to be emitted locally, the horizontal member 38 is separated and vertically. The housework sprayed at the end of the member 31 may be ignited using a torch to locally radiate the flame.

Referring to Figures 1 and 3 to 5, it will be described how to use the weed removal ignition 100 according to the present invention.

First, in the state in which the main valve 22 is locked, the connection hose 23 is coupled to the main supply pipe 21 and the holding pipe 32 and the extension pipe 33 are coupled. The lower end of the extension tube 33 is coupled to the horizontal member 38 and the first and second connectors 50 and 51 are mutually coupled.

When the horizontal member 38 is coupled, the radiation width of the flame is adjusted according to the situation at which the weed is removed. The first and second sliding pipes 43 and 47 are drawn out of the fixed pipe 39 so that the gas is drawn out. Is injected to determine the radiation width to emit flames. At this time, since the first and second sliding holes are fixed by the combination of the ball flanger 42 and the inlet groove 53, the first and second sliding holes can be easily slid.

When the coupling of the horizontal member 38 and the vertical member 31 is completed, the main valve 22 is opened while the control valve 35 is closed to allow gas to be discharged from the gas supply part 20 to the connection hose 23. . Gas is not injected through the horizontal member 38 by the control valve 35, and after opening the main valve 22, the user hangs the suspenders 12 of the wearing portion 10 on the shoulder. Wear 10.

Thereafter, the control valve 35 is opened to allow gas to be injected through the first and second injection holes 40 and 45, and then the switch 36 is pressed to cause the spark to ignite in the igniter 48. Ignite. By controlling the injection amount of the gas through the control valve 35 to properly adjust the intensity of the flame, weeds are removed by burning.

When the removal of the weed is completed, the control valve 35 is closed to block the injection of gas to remove the flame, and the main valve 22 is blocked.

After removal of the weeds, the horizontal member 38, the vertical member 31, and the connection hose 23 are sequentially separated in order in order to facilitate movement or storage.
