Abstract

PURPOSE:To efficiently and surely sterilize soil without unevenness by directly jetting combustion flame heat while tilling and turning soil surface layer. CONSTITUTION:For example, a combustor 4 composed of a blower 7 and a blowing port 8 is freely linked through a linking member 12 to the back of a body 2 of a carrier 11 equipped with a tiller 3 composed of a rotating shaft 5 and tilling and rotating tines 6. The aforementioned carrier 11 is run to directly blow combustion flame heat on tilled soil (B) with the combustor 4 to sterilize the soil (B) while tilling and turning the soil surface layer (A) with the tiller 3. Tilling and sterilization can be carried out by passing operation at a time. Since the sterilization can be performed simultaneously with the tilling, sterilization effects thereof are increased and operating efficiency is improved.

Since weeding work was carried out by injecting the hot air from the combustion flames only onto the surface of the farmland or weeds, the hot air from the combustion flames hit only the surface, and the soil clods were especially large, perhaps because it was not able to penetrate deep into the soil. In some cases, only a portion of the surface is exposed to the hot air from the combustion flames, so the efficiency of soil sterilization by the hot air from the combustion flames is very low, leading to problems such as the inability to perform soil sterilization evenly and uniformly. there were.

In J, when sterilizing agricultural land or other soil using the soil sterilization device according to the present invention, first connect the main body to the rear of a transport vehicle such as a tractor, then start the combustor, and perform powerful combustion. Hot flame air is injected from the injection port towards the soil surface layer. Once the strong combustion hot air is injected towards the soil surface layer as described above, start the tilling device and move the transport vehicle forward. The soil surface layer is tilled deeply or shallowly using a tilling device. By the way, since the main body is moved forward as the transport vehicle advances, as the main body advances, the surface layer of the freshly tilled soil is evenly exposed to the hot air of the injected powerful combustion flames. As a result, the soil that has been deeply dug up or pulverized by the tiller is quickly sterilized by direct contact with the injected hot air from the combustion flames.

したがって、農耕地における土壌殺菌がムラなく均等に

第２回目の殺菌が行われる。As the main body advances, the uncultivated surface layer of the soil is sterilized for the first time by being exposed to hot air from the powerful combustion flames injected from the injection port of the combustor installed at the front of the main body. The soil, which has been sterilized by being exposed to the hot air from the combustion flames, is immediately tilled by a rotating tiller. Then, the cultivated soil is efficiently exposed to the hot air of combustion flames that is vigorously injected from the injection port of the combustion machine located at the rear of the main body, and is sterilized for the second time.

殺菌作業を達成できる。Immediately after the soil surface layer was tilled using a tilling device installed on the front side of the main unit, it was sterilized with hot air from combustion flames injected from the injection port of a combustion machine installed on the rear side of the main unit. The hot air from the combustion flames obtained by the combustion machine installed on the front side of the main body is probably because it allows the hot air from the combustion flames to penetrate deeply into the crushed soil and sterilize it efficiently and evenly and reliably. While cultivating the surface layer of the soil that had been sterilized with the machine, the tilled soil was sterilized again using the hot air from the combustion flame from the combustion machine installed at the rear of the main unit, so even if it was only a single pass, the sterilization work could be done twice. This makes it possible to further enhance the soil sterilization effect and achieve more uniform sterilization work.
