Abstract
Description
[Technical Field]
[0001] The present invention relates to a traveling steam weed killer that can kill weeds by using high-temperature steam while traveling. [Background technology]
[0002] Generally, weeding is done by manually pulling out weeds one by one, or by cutting them down with a sickle or mower. However, these methods require a lot of time and money, and the weeds quickly regrow, meaning that the effectiveness of the weed control is short-lived.
[0003] In addition, spraying herbicides is a method of weed control that has a long-lasting effect, but herbicides have the fatal drawback of being dangerous, as they not only have a long-lasting toxicity that has a negative impact on the ecosystem, but also harm the health of workers and other passersby.
[0004] In response to this, methods and devices for removing weeds that utilize steam have recently been developed, and a representative example of such methods is disclosed in Patent Document 1.
[0005] However, the weed remover disclosed in the aforementioned Patent Document 1 not only failed to collect the weeds to be removed, but also failed to confine the steam, resulting in reduced weed removal efficiency.
[0006] Furthermore, the weed remover disclosed in Patent Document 1 has the problem that the operator must directly pull or push the weed remover, which causes fatigue for the operator, and there is also the problem that the weed remover cannot be moved, particularly on uneven sidewalk blocks. [Prior art documents] [Patent documents]

[Figure 5] FIG. 10 is a schematic diagram showing a traveling steam weed killing machine according to a third embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a traveling steam weed killer according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 of the accompanying drawings are schematic views showing a traveling steam weed killing machine according to a first embodiment of the present invention.
[0024] 1 to 3, the traveling steam weed killer (100) according to the first embodiment of the present invention includes a steam generator (120) that generates steam (S), a steam box (130) that guides weeds (W) to be killed into a weed killing area (A) formed inside the device, prevents the steam (S) sprayed into the weed killing area (A) from escaping to the outside, and maintains the temperature of the steam (S) for a certain period of time (heat retention), and traveling means (110) on which the steam generator (120) and the steam box (130) are mounted.
[0025] First, the propulsion means (110) is operated using electric energy or fossil fuel as a power source, and includes a body (112), a chassis (114), and front wheels (116) and rear wheels (118) for driving.
[0026] Of course, the propulsion means (110) includes an engine or motor for generating power, a power train, a steering system, a suspension system, and a brake system.
[0027] In the present invention, the traveling means (110) is not particularly limited, but as an example, the traveling means (110) may be any one of a normal low-speed electric vehicle, a normal golf cart, or a normal one-ton truck. As shown in Figures 1-3, a conventional golf cart is shown as the vehicle (110).
[0028] The steam generator (120) is mounted on the bed of the traveling means (110), and the steam box (130) is mounted (installed) on the chassis (114) between the front wheels (116) and rear wheels (118) of the traveling means (110) so as to face the ground on which the weeds (W) grow. The steam generator (120) uses electrical energy or fossil fuel as a power source to heat and evaporate water or to generate steam (S) by using ultrasonic vibrations.
[0029] The steam generator (120) supplies the generated steam (S) to the steam box (130) through the steam connection tube (122). Preferably, the steam connection tube (122) is wrapped in a jacket (not shown) to prevent heat loss. A cold water circulation channel (not shown) may be formed inside the jacket to circulate cold water so that the steam connection tube 122 can be quickly cooled after the weed killing operation is completed. Here, since the structure and operation of the steam generator (120) are well known in the art, a detailed description of the steam generator (120) will be omitted in the present invention.
[0030] The steam box (130) is formed in a box shape with a closed top and an open bottom, and a weed killing area (A) formed inside. At this time, the open lower part of the steam box (130) faces the ground where the weeds (W) grow, and is mounted (installed) on the chassis (114) so as to be spaced apart from the ground by a predetermined distance. Here, the reason why the lower part of the steam box (130) is spaced apart from the ground is to allow the weeds (W) to be killed to easily flow into the weed killing area (A).
[0031] In addition, 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 outward from the front and rear of the steam box (130), respectively. The weed guide plate (132) thus formed 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 so that its width gradually increases from the front and rear of the steam box (130) to the front outer side and rear outer side of the steam box (130), respectively, so that weeds (W) distributed over a wide area can be guided to the weed killing area (A).
[0033] Meanwhile, a steam injection pipe (134) for injecting the steam (S) generated by the steam generator (120) is installed in the weed killing area (A) of the steam box (130). The steam injection pipe (134) is bent so that steam (S) can be injected evenly over the entire weed killing area (A). For example, the steam injection pipe (134) may be bent into a square, oval, cylindrical, or regular star shape when viewed in a plane, 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 the steam (S) is applied passes through the steam box (120) so that the steam (S) can be guided from the steam generator (120), and the inlet end of the steam injection pipe (134) passing through the steam box (120) is connected to the steam connecting tube (122) extending from the steam generator (120).
[0035] In addition, a heat-retaining layer (138) is formed on the inner surface and top surface of the steam box (130) facing the weed-killing area (A) of the steam box (130) to block heat transfer between the weed-killing area (A) and the outside of the steam box (130) and to maintain the temperature of the steam (S) injected from the steam injection pipe (134) for a certain period of time. At this time, the lower end of the side of the heat insulating layer (138) formed on the inner surface of the steam box (130) is formed so as to come into contact with the weeds (W) and the ground on which the weeds (W) grow, so as to prevent the steam (S) from being discharged outside the steam box (130).
[0036] Such a heat-retaining layer (138) is made of a typical heat-resistant canvas that is flexible yet highly heat-resistant, for example, glass fiber coated with silicone, so that the heat-retaining layer (138) can avoid interference and allow the weeds (W) to be killed to flow into the weed-killing area (A).
[0037] As mentioned above, the heat-retaining layer (138) blocks heat transfer between the weed-killing area (A) and the outside of the steam box (130), maintaining the temperature of the steam (S) for a certain period of time while preventing the steam (S) from leaking outside the steam box (130). That is, the heat-retaining layer (138) prevents the steam (S) in the weed-killing area (A) from being discharged to the outside, 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] 4 and 5 are schematic diagrams showing traveling steam weed killers according to second and third embodiments of the present invention. Referring to Figures 4 and 5, the traveling steam weed killers (200, 300) according to the second and third embodiments of the present invention differ from the traveling 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 traveling means (110), respectively, and can be guided and pulled by the traveling means (110).
[0039] Here, the traveling steam weed killer (200, 300) according to the second and third embodiments of the present invention includes the same traveling means (110) and steam generator (120) as the traveling steam weed killer (100) according to the first embodiment of the present invention. The traveling steam weed killers (200, 300) according to the second and third embodiments of the present invention include a steam box (230, 330) identical to the steam box (130) of the traveling steam weed killer (100) according to the first embodiment of the present invention, but the steam box (230, 330) of the traveling steam weed killers (200, 300) according to the second and third embodiments of the present invention is different from the steam box (130) of the traveling steam weed killer (100) according to the first embodiment of the present invention in that it is provided with moving wheels (232, 332) so that it can be guided and pulled by the traveling means (110).
[0040] The moving wheels (232, 332) are installed on the front and rear sides of the steam box (230, 330) or on both sides of the center of the steam box (230, 330) as shown in Figures 4 and 5, and the moving wheels (232, 332) separate the bottom of the steam box (230, 330) by a predetermined distance from the ground where the weeds (W) grow.
[0041] The steam boxes (230, 330) can be connected to the front and rear sides of the traveling means (110) in a conventional manner so that they can be guided and towed by the traveling means (110).
[0042] The traveling steam weed killer (100, 200, 300) according to the first to third embodiments of the present invention is capable of traveling, which not only significantly reduces the fatigue of the worker involved in weed (W) killing work, but also makes it possible to effectively kill weeds (W) even on uneven sidewalk blocks.
[0043] The traveling steam weed killer (100, 200, 300) according to the first to third embodiments of the present invention can induce weeds (W) into a weed killing area (A) formed inside a steam box (130, 230, 330) and confine high-temperature steam (S) within the weed killing area (A) to prevent it from being released to the outside, thereby significantly improving the efficiency of killing weeds (W).
[0044] The traveling steam weed killers (100, 200, 300) according to the first to third embodiments of the present invention use high-temperature steam (S) to eradicate not only the weeds (W) but also various pests and microorganisms such as viruses and bacteria that cause diseases or adversely affect the growth of plants.
