Microorganism sampling device

Abstract

The invention relates to the field of microorganism extraction, in particular to a microorganism sampling device. The technical problem to be solved by the invention is to provide a microorganism sampling device. According to the technical scheme, the microorganism sampling device comprises a lower-layer soil extraction mechanism, a screening mechanism, a second electric lifting column and the like, an operation control screen, a transmission control mechanism, a first electric lifting column and a screening mechanism are sequentially connected to the upper portion of the working main bottom plate. Remote automatic soil taking is carried out on soil in a flower bed and a lawn center area where manual sampling cannot be carried out manually, and hard soil blocks on the surface layer of thesoil in the obtained soil sample are separated to obtain active soil which is moist and active and contains bacillus subtilis below the surface layer of the soil, and stones, grass roots, soil insectsand other impurities in the loose and moist soil below the surface layer of the soil are separated to obtain the effect of pure active soil.

Description

technical field [0001] The invention relates to the field of microorganism extraction, in particular to a microorganism sampling device. Background technique [0002] Microorganisms include: bacteria, viruses, fungi, and some small protists, microscopic algae, etc., which are small and closely related to humans. Covering many types of beneficial and harmful, widely involved in food, medicine, industry and agriculture, environmental protection, sports and many other fields. In Chinese textbooks, microorganisms are divided into the following eight categories: bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, and spirochetes. Some microorganisms are visible to the naked eye, such as mushrooms, ganoderma lucidum, and shiitake mushrooms that belong to fungi. Microorganisms are a class of "non-cellular organisms" composed of a few components such as nucleic acids and proteins. [0003] At present, the research on microorganisms often needs to extract m...

Problems solved by technology

[0005] In order to overcome the microbial research work including the extraction of microorganisms in the soil, soil sampling is often carried out in places where biological activities are relatively active, such as flower beds and lawns. During the artificial soil extraction process, in order to protect the vegetation of flower beds and lawns, and then Soil extraction workers cannot enter the central area of ​​lawns and flower beds for soil collection, and can only manually collect soil in the surrounding areas of flower beds and lawns. At the same time, the surface soil of some flower beds and lawns is relatively hard, and the activity of the surface soil is low. After extraction, it is necessary to Manual removal of the hard soil clods led to the inability to take soil samples from places with frequent biological activities in the central area of ​​flower beds and lawns when soil samples were taken manually. Only soil samples from the periphery of flower beds and lawns were obtained. The content of various microorganisms is extreme and cannot represent the microbial content level of the entire flower bed. At the same time, when soil excavation is carried out manually, the hard soil on the surface must be shoveled, and the loose soil under the hard soil on the surface is taken out, and then excavated. During the process, part of the hard soil on the surface is crushed and mixed into the loose soil below, and then the humidity in the obtained soil sample is reduced, the biological activity is reduced, and the biological content is reduced, which increases the difficulty of subsequent soil microbial extraction. The technical problem is: to provide a microbial sampling device
