Efficient soil disinfection and fertilization device

Abstract

The invention discloses an efficient soil disinfection and fertilization device. The efficient soil disinfection and fertilization device comprises a frame, a rotating drum is arranged among the support legs of the frame, and the left of the rotating drum is fixedly connected with a shovel bucket; a first driving shaft is arranged inside the rotating drum and fixedly connected with first spiral blades. The efficient soil disinfection and fertilization device can dig out deep soil through the shovel bucket and the rotating drum, stir the soil through the spiral blades and crush clods through crushing blades; the efficient soil disinfection and fertilization device also comprises a steam generating device, which can generate steam and uniformly and efficiently heat the soil through circumferentially-distributed atomizing spray nozzles to greatly improve the soil disinfecting efficiency and effects; the crushing blades and a grinding barrel can crush fertilizer into powder and then the spiral blades can efficiently mix the powder fertilizer with the soil to improve the fertilizer application uniformity and effects, to save fertilizer and to improve the working efficiency.

Description

technical field [0001] The invention relates to the field of soil treatment, in particular to an efficient soil disinfection and fertilization device. Background technique [0002] Soil disinfection is an efficient and rapid technology to kill fungi, bacteria, nematodes, weeds, soil-borne viruses, underground pests and rodents in the soil. It can well solve the problem of repeated cropping of high value-added crops and significantly improve crop yield yield and quality. [0003] Traditional chemical disinfection methods may cause disinfectant residues, change the composition of the soil, and then affect the growth of crops; using steam disinfection can better maintain the original composition of the soil and do not introduce new substances. Traditional steam disinfection devices have low efficiency. The function is single and needs to be improved; in addition, in the process of improving soil fertilizer efficiency, artificially spreading solid fertilizer not only consumes a...

[0003] Traditional chemical disinfection methods may cause disinfectant residues, change the composition of the soil, and then affect the growth of crops; use steam disinfection to better maintain the original composition of the soil and not introduce new substances. Traditional steam disinfection devices have low efficiency. The function is single and needs to be improved; in addition, in the process of improving soil fertilizer efficiency, artificially spreading solid fertilizer not only consumes a lot of physical strength, but also has low efficiency and poor uniformity of spreading, resulting in a large amount of chemical fertilizer
