High-temperature sterilization soil-disinfesting machine

Abstract

The invention relates to agricultural machinery, in particular to a high-temperature sterilization soil-disinfesting machine for killing bacteria and insects in soil. The high-temperature sterilization soil-disinfesting machine comprises a box with a bottom opening, and a flame torch disposed on the box. The high-temperature sterilization soil-disinfesting machine is characterized in that a balance soil scraper is arranged at the bottom of the box, a soil inlet is arranged on a front wall board of the box above the balance soil scraper, a soil-taking roller is disposed inside the box at the rear of the balance soil scraper, the soil-taking roller is rotatably disposed on the side wall of the box through bearings at two ends, an axis of the soil-taking roller is parallel to the balance soil scraper, and soil cutters are evenly and circularly arranged on the soil-taking roller, the soil-taking roller is in drive connection with a power mechanism through a drive device, and the flame torch inside the box is disposed above the soil-taking roller. The high-temperature sterilization soil-disinfesting machine is capable of turning up soil about 25cm in thickness and sterilizing and disinfesting the soil by the flame torch, thereby thoroughly eliminating harmful bacteria and insects in the soil and avoiding pesticide pollution. The high-temperature sterilization soil-disinfesting machine is simple in structure, convenient to operate and low in overall weight, and flame jet is high in temperature. The high-temperature sterilization soil-disinfesting machine bakes the soil twice instantly and has the fine effect of efficiently killing the bacteria and insects in the soil.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a high-temperature sterilizing soil insecticide, which is a device for killing bacteria and insects in the soil. Background technique [0002] At present, vegetables and melons and fruits in most rural areas are planted with plastic film or switched to greenhouses, and greenhouse vegetables have become mainstream products in the market. When planting with plastic film or switching to greenhouse planting, the suitable environment will cause the bacteria and insects in the soil to multiply and grow rapidly. In order to eliminate the harmful bacteria and insects in the soil, most people use chemical pesticides to kill insects on the soil before planting crops. Most of the chemical pesticides contain harmful substances, which remain in the growing vegetables and seriously endanger human health and the growth of livestock. Because some harmful insects, especially root-knot nematodes, have a...
