Description

[0001] The present invention relates to a steam sterilizer machine with a tillage operation function,

The present invention relates to a steam type soil disinfection apparatus, and more particularly, to a steam type soil disinfection apparatus, more particularly, to a method of disinfecting a steam type soil disinfection apparatus, The present invention relates to a sterilizing apparatus for sterilization of a soil having a tilling operation function which is uniformly transmitted over the whole area of the soil and disinfected in a short time to improve the efficiency and reliability of disinfection work for the soil.

Recent agriculture has adopted large-scale farming facilities such as greenhouses to employ enterprise-type farming, which is based on climate-dependent conventional farming methods and that is shipped through multi-cropping plants that grow vegetables and fruits have.

This type of farming is a series of successive cultivations of similar crops, which cause crop failure and poor crop yield and quality.

There are many reasons for the sequence disorder, but the most direct cause is that it is due to the concentration of certain pests as a result of continuous cultivation of the same or similar crops in one place.

On the other hand, the grass planted like a golf course has many pests and breeds that damage the lawn or the ground condition of the golf course.

In addition, in sandy areas equipped with facilities in parks, kindergartens, kindergartens, schools, etc., there is a need to manage sterilization of the harmful bacteria such as general germs and pathogenic bacteria due to the excretion of the dogs and the surrounding bacteria exposure environment. This is not true.

And, in summer beaches, there are many people who walk with bare feet on the beach with their shoes. The people are so bright that the sandy beach becomes a hotbed of athlete's foot. There is a possibility that beach sand is mixed with urban pollutants and wild animal feces. Sand play such as sand casting, stabbing, eye disease, skin disease, ear infection, wound infection can occur.

Conventionally, a large amount of pesticides or coating sterilization methods have been used for disinfecting and disinfecting specific pests in the soil for such various purposes.

However, such a large amount of pesticide spraying has harmed the health of workers and consumers, has caused not only harmful pests in the soil but also useful microorganisms to be killed, thereby causing a problem of inhibiting the growth of crops. In recent years, The excessive use of pesticides is strictly regulated.

Accordingly, it is necessary to find a way to remove pests that are environmentally friendly instead of spraying pesticides.

Therefore, in order to solve the problems of pest insect pest control and soil disinfection through such pesticides, the applicant of the present invention has proposed a method of supplying high temperature steam to the soil through Korean Patent Registration No. 10-1331416 " Sterilizing equipment.

By using the steam sterilizer, it is possible to create a safety zone by insecting and sterilizing by using high temperature steam which continuously injects pests or harmful bacteria in the soil.

However, such a steam insecticide disinfection apparatus does not perform tillage operations, that is, does not perform the operation of turning the soil so as to soften the surface of the soil and improve the breathability and water management, It is difficult to uniformly disinfect the whole area of the soil because the sand bar is inserted into the soil.

In addition, when the settling bar provided with the gap is caught on the stone, there is a problem that the barb is bent or is damaged by the structure of the barb, and the efficiency of the disinfection operation is low.

Accordingly, it is required to develop a soil disinfection device capable of disinfecting more area in a deeper position within a short time and performing tillage work so as to uniformly disinfect the entire area of the soil.
