Description

Technical Field

[0001] This utility model relates to the field of soil microbial degradation technology, and more specifically, to a soil microbial degradation device. Background Technology

[0002] Soil microbial degradation is the process by which bacteria, fungi and other microorganisms decompose organic pollutants (such as petroleum, pesticides and organic waste) in the soil through their metabolic activity.

[0003] Chinese patent document CN219851355U discloses a soil microbial degradation device. This device achieves efficient spraying of microbial agents by setting up structures such as a microbial agent holding box and soil turning teeth, which can improve soil remediation efficiency to a certain extent.

[0004] However, there is still room for optimization in maintaining the activity of the microbial agent. Strict environmental conditions are required during the fermentation and application of microbial agents, especially the stability of humidity and temperature, which has a decisive impact on the reproduction and decomposition efficiency of microorganisms.

[0005] If the humidity is too low, the microorganisms in the inoculant will lose their activity due to dehydration, affecting the effectiveness of soil microbial degradation. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a soil microbial degradation device, which has the following beneficial effects:

[0020] 1. High-efficiency humidity maintenance and ventilation control

[0021] This invention significantly improves the environmental stability of soil microbial degradation through the synergistic effect of the protective mulch film and the perforated structure. After the mulch film is precisely laid by the edge-pressing wheel, the perforating column driven by the electric push rod forms breathable micropores on the mulch film at a controllable frequency, which reduces water evaporation and ensures oxygen exchange. The soil compaction head compacts the soil to the edge of the mulch film, forming a closed microenvironment, which prolongs the duration of microbial activity compared to traditional open-air degradation methods.

[0022] 2. Automated integrated operation system

[0023] The device employs a multi-module linkage design driven by a vehicle, achieving full automation of the spraying, mulching, perforation, and compaction processes. The spray pipes, in conjunction with the mixing components of the storage tank, maintain the bacterial agent in suspension through impeller rotation, preventing uneven concentration caused by sedimentation. The electric cylinder allows for adjustable mounting height to adapt to different terrains, and the spring-buffered pressure roller structure maintains stable mulching pressure even on undulating ground.

[0042] In summary:

[0043] In use, the entire structure is moved by the drive vehicle 1. Before microbial degradation, the land needs to be turned over, which can be done by an existing tiller.
