Abstract

PURPOSE:To simply remove weeds completely without using a herbicide by spraying and injecting a high-temperature liquid such as hot water to roots of weeds to necrotize cells of root part. CONSTITUTION:A high-temperature spray liquid such as hot water or vegetable heated water is injected to roots of weeds and cells of weed part are necrotized to wither the whole weeds. To be concrete, for example, a burner 2 of a weeder is ignited and as a waste edible oil in a spray liquid tank 3 is heated to 200 deg.C a hand truck 1 is moved near to weeds. Then a spray tube 8 is positioned right above the weeds, a handle 1a is pushed down and the spray tube 8 is thrust from roots of weeds into underground roots. Successively, a motor M is started and a cam push type piston 6 is operated to vigorously inject the heated waste edible oil, sent from a discharge outlet 4a of a spray liquid tank 4 to a vertical cylinder 7, from the spray tube 8 into roots or underground roots.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for effectively removing weeds growing on lawns of golf courses and the like, and a weeding machine for carrying out the method.

[0002]

The use of chemical herbicides to remove weeds damages the entire surface of the earth and causes pollution problems. Also, with the method of cutting or burning off only the surface portion, it is impossible to completely wither because it is not so-called rooting, and most of it regenerates, and weeding work must be frequently performed.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, the present invention injects a high-temperature jetting liquid such as boiling water into the roots or ground roots of weeds to cause necrosis of the cells of the roots and ground roots. I try to kill the whole. Further, in order to carry out the method, an attempt is made to provide a weeding machine that aims at only the weeds and does not lose the amount of heat and allows the worker to easily work in a standing posture.

[0004]

In order to achieve the above object, the present invention is to inject a hot jet liquid such as boiling water or vegetable heating oil into the root of a weed to cause necrosis of cells in the root, resulting in It is a weed removal method characterized by dying all weeds. Then, a burner-2 with a fuel tank 3 is provided on the hand-held cart 1 for carrying out this weed removal method.
The weeding machine is provided with a jetting liquid tank 4 facing the heating part 2a of the burner-2, and a jetting means 5 to a jetting pipe 8 associated with a discharge port 4a of the jetting liquid tank 4. In the above weeder, the spraying means 5 may be configured by a combination of a steam operation valve and a spray pipe 8 if the pressure (steam pressure) is used because steam is generated when the sprayed liquid uses hot water. However, when using vegetable heating oil, for example, waste oil for heating food, it is necessary to perform constant pressure injection from the injection pipe 8, and as an ideal mode thereof, the cam pressing piston 6 driven by the motor M is used. Prepare

[0005]

EXAMPLE An example of a weeding machine for carrying out the weed removing method of the present invention is shown in FIGS. 1 and 2. That is, 1 is a two-wheeled hand-held cart having a hand-held handle 1a, and a burner-2 with a fuel tank 3 and a burner-2 on the machine base 1b.
Each of the injection liquid tanks 4 is mounted while holding the ventilation passage 9 so as to face the heating portion 2a. A cam pressing type piston 6 driven by the motor M is attached to the discharge port 4a of the jet liquid tank 4.
The vertical cylinder 7 is communicated via the one-way valve 4b, and the injection pipe 8 is vertically connected to the tip of the vertical cylinder 7 via the one-way valve 7a.
In the figure, 10 is a drive pinion of the motor, 11 is a reduction gear that meshes with the motor, 12 is an eccentric cam fixed coaxially with the reduction gear 11, 13 is a piston shaft associated with the eccentric cam 12, and 14 is the It is a return spring of the piston shaft 13.

[0006]

Now, the operation of the present invention will be described based on the weeding machine of the embodiment. An operator ignites the burner-2 to heat the edible waste oil in the injection liquid tank 3 to around 200 ° C. When weeds are found while pushing the hand push handle 1a, the jet pipe 8 is positioned directly above the push handle 1a and the handle 1a is pushed down to pierce the root of the weed into the root of the weed. At the same time, the hand switch S is turned on and the motor M Is started and the cam pressing piston 6 is operated. Then, from the discharge port 4a of the injection liquid tank 4 through the one-way valve 4b to the vertical cylinder-
The heated edible waste oil sent to the inside 7 is compressed by the piston 6, pushes the one-way valve 7a of the vertical cylinder 7 open, and is vigorously injected from the injection pipe 8 to the root or the underground root. As a result of the experiment, the unit injection amount at this time is 5 to 1
0cc is desirable. Thus, the roots or ground roots of the weeds are exposed to the hot jetting liquid to completely kill the cells of the roots, and as a result, the entire weeds (ie stems and leaves) are also killed.

[0007]

The present invention is as described above. As a result, hot water, vegetable hot oil, or other high-temperature injection liquid is injected into the roots of weeds to cause necrosis of the cells in the roots, resulting in the loss of the regeneration power of the weeds. , Can eradicate all weeds. In the weeding machine for carrying out the method, there is no loss of heat because it shoots only weeds. When weeds are found while pushing the hand-push handle, stop the operation, slightly lower the hand-push handle, pierce the weed root into the weed root, and turn on the hot liquid jet switch. Especially when vegetable oil such as edible waste oil is used as the high temperature injection liquid, a small amount of injection is sufficient because the retained calories are high,
In addition to the soil sterilization effect, it has a secondary effect of promoting the growth of grass after treatment. It goes without saying that edible waste oil contributes to the economic efficiency of using waste and prevention of pollution.
