Soil disinfecting subsoiler with flame deep layer sterilizing function and method

Abstract

The invention provides a soil disinfecting subsoiler with a flame deep layer sterilizing function and a method. The soil disinfecting subsoiler comprises a machine frame, a subsoiler compacting device and a high-temperature sterilizing device. The machine frame is used for supporting and fixing other devices and connected with a tractor hanging system in a hanging or traction mode and provides power for the tractor hanging system. The subsoiler compacting device is used for completing the soil deep loosening and land preparing work and the breaking and compacting work of earth surface soil blocks. The high-temperature sterilizing device is used for realizing fire spraying of multiple fire spraying heads to complete the high-temperature soil sterilizing and insect killing work. By means of the high-temperature flame sterilizing and insect killing mode, oxygen-enriched combustion gas is sprayed at a high speed through a space formed by turning soil at the rear portion of a subsoiler shovel handle underground, flame is located underground during combustion and used for killing bacteria, and the energy utilization rate is high; targeted soil disinfecting work is conducted for large fields with soil of different pollution conditions, the pollution caused for the environment and crops by using highly poisonous chemical pesticides is solved, and the aim of improving the environment is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a soil disinfection subsoiler and a method for deep flame sterilization, which realize high-temperature, high-efficiency insecticidal and sterilized soil disinfection operations while subsoiling. technical background [0002] At present, in my country's agricultural production, highly toxic chemical pesticides are still used in the prevention and control of bacterial diseases and insect pests in the soil. The soil is sterilized before crops are planted, hoping to achieve the purpose of improving the soil to kill diseases and insect pests. On the one hand, perennial pesticides Bacteria will cause great harm to the soil, the environment, and humans and animals. On the other hand, chemical pesticides are used all year round, and diseases and insect pests have developed resistance to pesticides. The control effect is getting worse and worse, and the dosage of pesticides ha...

Problems solved by technology

[0004] After searching the literature of the prior art, it was found that the Chinese invention patent "Soil Disinfection High Temperature Sterilization and Antivirus Vehicle" patent application number 200710015138.9 uses an electric heating device. When the rotary tiller blade cuts the soil, the heating device generates high temperature to sterilize and kill insects. However, in this form, the heat source and the soil are only in contact with the inner surface of the rotary tiller cover, and the heat is easily lost with the air, and it is difficult to achieve the effect of completely killing bacteria, diseases and insect pests.

Chinese Invention Patent "Deep Soil High Temperature Insecticide Sterilizer" Patent Application No. 201410725504.X uses rotary tiller blades to lift the soil onto the conveyor belt, and then performs flame sterilization and insecticide, so as to achieve the effect of loosening the soil and exterminating insects. Rotary tillage is only carried out on the surface soil of the field, and does not break the bottom layer of the plow to fundamentally loosen and plow the land; at the same time, the rotary tiller only raises a small amount of surface soil, and the sterilization effect on the soil below the surface is not ideal; the existing soil is disinfected The equipment is mostly used for disinfection during rotary tillage and land preparation, and has not been well combined with subsoiling technology; the existing field soil is seriously compacted, and most of the existing disinfection equipment uses flames to physically disinfect the surface soil, which has not achieved palliative effect
