Deep rotary tillage soil high-temperature aerial fog disinfection combined machine based on low-frequency ultrasonic resonance and working method

Abstract

The invention discloses a deep rotary tillage soil high-temperature aerial fog disinfection combined machine based on low-frequency ultrasonic resonance and a working method, and relates to the fieldof agricultural machinery. The machine comprises a rotary tillage knife roll, the rotary tillage knife roll comprises a rotary tillage knife shaft, rotary tillage blades and spiral blades, the plurality of groups of spiral blades are uniformly distributed on the rotary tillage knife shaft in the axial direction, the spiral blades are mounted at the lower end of the rotary tillage knife shaft, therotary tillage knife shaft is of a hollow structure, a low-frequency ultrasonic resonance device is arranged in the hollow structure, the low-frequency ultrasonic resonance device can rotate along with the rotary tillage knife shaft, and the low-frequency ultrasonic resonance device sprays gas with a certain temperature to soil so as to disinfect the soil through aerial fog. According to the method, the high-temperature gas is used for carrying out disinfection and sterilization on the soil, a traditional soil disinfection mode is effectively replaced, the cost is advantageously saved, and pollution to the environment and the soil is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a high-temperature aerosol antivirus combined operating machine for deep rotary tillage soil based on low-frequency ultrasonic resonance and a working method. Background technique [0002] With the increase of the population, the demand for food and other agricultural products has increased. Due to the limited land area that can be planted, there is a phenomenon of repeated cropping of a piece of land year after year. At the same time, under the influence of the environment and climate, the types of pathogenic bacteria and This phenomenon will seriously affect the planting and growth of crops. [0003] Soil disinfection technologies currently on the market mainly include chemical disinfection, physical disinfection and biological fumigation. Among them, the cost of chemical disinfection technology is relatively low but causes greater pollution to the soil and th...

Problems solved by technology

Among them, the cost of chemical disinfection technology is relatively low but causes greater pollution to the soil and the environment; physical disinfection technology mainly includes solar heating disinfection (lower efficiency, and affected by weather temperature), steam disinfection (the machine is more cumbersome and consumes more energy) ), hot water disinfection (the machine is cumbersome and consumes a lot of energy), flame disinfection (it consumes a lot of fuel and is easy to cause fire), etc.; biological fumigation and disinfection technology uses organic substances from Cruciferae or Compositae to release toxic The gas kills the pests and germs in the soil. The operation process of this method is more complicated, and the factors of temperature, humidity and weather need to be considered
