Weeding device using steam and unmanned control system for green house using it {STEAM EXJECTION TYPE WEEDING APPARATUS AND AUTOMATIC CONTROL SYSTEM FOR GREEN HOUSE USING THE SAME}

The present invention relates to a weeding device using steam and an unmanned control system using the same, and in detail, indirectly controlling pests by stably removing weeds using steam without using harmful chemicals such as herbicides. At the same time, it is related to a weeding device using steam that can minimize damage to crops by preserving healthy soil and adjusting the intensity of steam according to the degree of weed growth, and an unmanned green house control system using the same.

In general, weeds that grow lushly around crop cultivation areas and barns not only interfere with the growth of crops, but also cause pests and diseases, and weeds around roads and sidewalks damage the aesthetics and interfere with traffic. Is being implemented.

Conventional weeding work is a method of manually removing weeds by hand or cutting and removing them using a sickle or mower, but there is a problem that manpower cost and work time are largely lost because such weeding work requires mobilization of a large number of manpower. . In addition, since the weeds are revived as time elapses, the lasting effect of weeding is short, and the removed weeds have to be separately collected and removed.

Accordingly, in order to reduce the loss of manpower and time required for weeding work, a method of spraying herbicides (pesticides) having a great lasting effect of weeding has emerged, but herbicides are very toxic hazardous chemicals, which protect the health of workers who spray them. It harms, and pesticide ingredients enter and accumulate into the human body through agricultural crops, causing harm to the health of people who eat the agricultural products.

In addition, herbicides can kill various insects and disrupt the ecosystem by destroying the upper food chain such as amphibians, reptiles and birds that feed on these insects. In addition, by remaining in the soil for a long time, not only pests that are harmful to cultivation, but also microorganisms useful for cultivation are killed together, rather inhibiting the growth of crops, or herbicides introduced into the soil or rivers can cause destruction of the soil and water environment.

Accordingly, development of technology for a herbicide that can provide safe agricultural products by preserving healthy soil while stably removing weeds and stably removing weeds in a nature-friendly manner without relying on chemicals such as herbicides is required. Is required.
