[0001] The present invention relates to a traveling steam weed killer that can kill weeds by using high-temperature steam while traveling.

Background Art

[0002] Generally, the mainstream methods of weed control are manually pulling out weeds one by one and using a sickle or a lawn mower to cut and remove them. However, such weed control requires a great deal of cost and time, and since weeds regrow in a short time, there is a limitation in that the lasting effect of weed control is short.

[0003] In addition, as a weed control method with a large lasting effect, there is a method of spraying herbicides. However, herbicides have the fatal drawback of being dangerous, as they not only have a long-lasting toxicity that adversely affects the ecosystem but also harm the health of workers and other passers-by.

[0004] In contrast, recently, weed control methods and devices using steam have been developed, and Patent Document 1 can be cited as a typical example.

[0005] However, the weed killer disclosed in the aforementioned Patent Document 1 not only could not collect the weeds to be removed but also could not confine the steam, resulting in a problem of reduced weed control efficiency. <00othat the weed killer disclosed in the aforementioned Patent Document 1 not only could not collect the weeds to be removed but also could not confine the steam, resulting in a problem of reduced weed control efficiency.

[0006] Furthermore, the weed killer disclosed in Patent Document 1 has the problem that the operator has to directly pull or push the weed killer, resulting in a high level of operator fatigue. In particular, on uneven sidewalk blocks, there is a problem that the weed killer cannot be moved.

Mode for Carrying Out the Invention

[0023] Hereinafter, embodiments embodying a traveling steam weed killer according to the present invention will be described in detail with reference to the drawings. Among the attached drawings, FIGS. 1 to 3 are diagrams schematically showing a traveling steam weed killer according to a first embodiment of the present invention.

[0024] Referring to FIGS. 1 to 3, a traveling steam weed killer (100) according to a first embodiment of the present invention includes a steam generator (120) that generates steam (S), and weeds (W) to be weeded in a weeding area (A) formed inside are guided while preventing the steam (S) injected into the weeding area (A) from being released to the outside, and a steam box (130) that allows the temperature of the steam (S) to be maintained (heat retained) for a certain period of time, and a traveling means (110) on which the steam generator (120) and the steam box (130) are mounted.

[0025] First, the traveling means (110) is operated using electric energy or fossil fuel as a power source, and the traveling means (110) includes a vehicle body (body; 112), a chassis (chassis; 114), and front wheels (116) and rear wheels (118) for traveling.

[0026] Of course, the traveling means (110) includes an engine or motor that generates power, a power train, a steering system, a suspension system, and a brake system.

[0027] In this invention, the means of transport (110) is not particularly limited, but as an example, the means of transport (110) may be any one of the following: a regular low-speed electric vehicle, a regular golf cart, or a regular 1-ton truck. As shown in Figures 1 through 3, a standard golf cart is shown as the means of transport (110).

[0028] The steam generator (120) is mounted on the cargo bed of the vehicle (110), and the steam box (130) is mounted (installed) on the chassis (114) between the front wheels (116) and rear wheels (118) of the vehicle (110) so as to face the ground where the weeds (W) are growing. The steam generator (120) uses electrical energy or fossil fuels as a power source to heat and evaporate water, or generates steam (S) using ultrasonic vibrations.

[0029] Such a steam generator (120) supplies the generated steam (S) to the steam box (130) via a steam connecting tube (122). Preferably, the steam connecting tube (122) may be enclosed by a jacket (not shown) to prevent heat loss, although this is not shown. Furthermore, a cold water circulation channel (not shown) may be formed inside the jacket to allow for the rapid cooling of the steam connecting tube (122) after the weed-killing work is completed. Since the configuration and operation of the steam generator (120) are known technologies, a detailed description of the steam generator (120) is omitted in this invention.

[0030] The steam box (130) is formed in a box shape with the top closed and the bottom open, and a weed-killing area (A) formed inside. At this time, the open lower part of the steam box (130) is mounted (installed) on the chassis (114) so ​​as to be separated from the ground at a predetermined distance, with the weeds (W) growing on it facing the ground. The reason for separating the bottom of the steam box (130) from the ground is to allow the weeds to be killed (W) to flow easily into the weed-killing area (A).

[0031] Furthermore, vertical, plate-shaped weed guide plates (132) are formed on both sides of the front outer surface and both sides of the rear outer surface of the steam box (130), extending outwards from the front and rear outer surfaces, respectively. The weed guide plate (132) formed in this manner guides the weeds (W) to be killed into the weed-killing area (A) formed inside the steam box (130) when the traveling means (110) is operated (forward and backward).

[0032] Preferably, the weed guide board (132) can be extended from the front and rear of the steam box (130) to the front and rear outer sides of the steam box (130), respectively, so as to guide weeds (W) distributed over a wide area to the weed-killing area (A), with its width gradually increasing.

[0033] Meanwhile, a steam injection pipe (134) is installed within the weed-killing area (A) of the steam box (130) to inject steam (S) generated by the steam generator (120). The steam injection tube (134) is bent to allow steam (S) to be evenly injected over the entire weed-killing area (A). For example, the steam injection tube (134) may be bent into a square, elliptical, cylindrical, or conventional star shape when viewed in plan, with steam injection holes (136) spaced apart along the bent shape.

[0034] At this time, the inlet end of the steam injection pipe (134) to which steam (S) is applied penetrates the steam box (120) so that steam (S) can be guided from the steam generator (120), and a steam connecting tube (122) extended from the steam generator (120) is connected to the inlet end of the steam injection pipe (134) that has penetrated the steam box (120).

[0035] Furthermore, an insulating layer (138) is formed on the inner and upper surfaces of the steam box (130) that face the weed-killing area (A) of the steam box (130), which blocks heat transfer between the weed-killing area (A) and the outside of the steam box (130), and allows the temperature of the steam (S) sprayed from the steam injection pipe (134) to be maintained at that temperature for a certain period of time. At this time, the lower side of the heat-insulating layer (138) formed on the inner surface of the steam box (130) is formed to be in contact with the weeds (W) and the ground on which the weeds (W) are growing, so that the steam (S) is not discharged to the outside of the steam box (130).

[0036] Such a heat-insulating layer (138) is formed from a conventional heat-resistant canvas that is flexible yet highly heat-resistant, for example, glass fiber coated with silicone, so that the heat-insulating layer (138) avoids interference and allows the weeds to be killed (W) to flow into the weed-killing area (A).

[0037] Furthermore, the insulation layer (138) blocks heat transfer between the weed-killing area (A) and the outside of the steam box (130), as described above, thereby maintaining the temperature of the steam (S) for a certain period of time, while also preventing the steam (S) from leaking out of the steam box (130). In other words, the heat-insulating layer (138) prevents steam (S) from being discharged to the outside of the weed-killing area (A) while blocking heat transfer between the weed-killing area (A) and the outside of the steam box (130), thereby significantly increasing the efficiency of weed-killing (W).

[0038] Figures 4 and 5 are schematic diagrams showing the mobile steam weed killer according to the second and third embodiments of the present invention. Referring to Figures 4 and 5, the mobile steam weed killers (200, 300) according to the second and third embodiments of the present invention differ from the mobile steam weed killer (100) according to the first embodiment of the present invention in that the steam boxes (230, 330) are installed on the front (see Figure 4) and rear (see Figure 5) sides of the mobile means (110), respectively, and can be guided and towed by the mobile means (110).

[0039] Here, the mobile steam weed killers (200, 300) according to the second and third embodiments of the present invention include the same mobile means (110) and steam generator (120) as the mobile steam weed killer (100) according to the first embodiment of the present invention. Furthermore, the mobile steam weed killers (200, 300) according to the second and third embodiments of the present invention include the same steam box (230, 330) as the mobile steam weed killer (100) according to the first embodiment of the present invention. However, unlike the steam box (130) of the mobile steam weed killer (100) according to the first embodiment of the present invention, the steam boxes (230, 330) of the mobile steam weed killers (200, 300) according to the second and third embodiments of the present invention are equipped with mobile wheels (232, 332) so that they can be guided and towed by a driving means (110).

[0040] As shown in Figures 4 and 5, the transport wheels (232, 332) are installed on the front and rear sides of the steam box (230, 330) or on both sides of the central part of the steam box (230, 330), and the transport wheels (232, 332) separate the lower part of the steam box (230, 330) from the ground where weeds (W) are growing by a predetermined distance.

[0041] The steam boxes (230, 330) can be connected to the front and rear sides of the running gear (110) in a conventional manner so that they can be guided and towed by the running gear (110).

[0042] The mobile steam weed killers (100, 200, 300) according to the first to third embodiments of the present invention are mobile, which not only significantly reduces the fatigue of the worker associated with weed (W) killing work, but also allows for effective weed (W) killing even on uneven sidewalk blocks and the like.

[0043] The mobile steam weed killer (100, 200, 300) according to the first to third embodiments of the present invention can guide weeds (W) into a weed-killing area formed inside a steam box (130, 230, 330) and confine the high-temperature steam (S) within the weed-killing area (A) so that it is not released to the outside, thereby significantly increasing the efficiency of weed (W) killing.

[0044] The mobile steam weed killers (100, 200, 300) according to the first to third embodiments of the present invention eliminate not only weeds (W) but also almost all microorganisms such as viruses or bacteria that induce diseases or adverse effects on plant growth, as well as various pests and diseases, using high-temperature steam (S) when killing weeds (W).
