Abstract

The invention discloses a soil sampler for biological soil enzyme activity determination. The soil sampler comprises a handheld rod and a limiting frame; the lower end of the handheld rod is fixedly connected with the limiting frame; a movable sleeve is fixedly connected to the middle of the limiting frame; the lower end of the handheld rod is symmetrically connected with one ends of two telescopic rods; when a motor rotates, a rotating shaft can be driven to rotate, so that a sampling cylinder is driven to move downwards; the sampling cylinder can move downwards better due to the existence ofa spiral blade, so that the sampling can be performed better, the manual sampling is facilitated, and the labor force is reduced; the lower end of the spiral blade and the lower end of the sampling cylinder adopt conical structures, and in the sampling process, the sampling cylinder can enter the soil more easily, so that the sampling efficiency is improved; after the sampling is finished, in theprocess that a scraping plate moves downwards, a soil sample is pushed downwards, so that the soil sample is pushed out; and meanwhile, the inner side wall of the sampling cylinder is scraped by thescraping plate so as to ensure that the next sampling can be very smooth.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a soil sampler for measuring biological soil enzyme activity. Background technique [0002] Soil is the substrate of terrestrial plants. Soil provides essential nutrients and water for plants. Many important processes in the ecosystem are carried out in soil, especially the decomposition and nitrogen fixation process completed by microorganisms. The soil in different regions Moisture, nutrient content and microbial content vary widely, so it is necessary to sample the soil before planting crops. [0003] Chinese document is a kind of soil sampler of CN108444753A, the guide frame is vertically placed on the soil, guarantees the verticality between the guide frame and the horizontal plane when static, utilizes the guide frame to ensure the verticality when the sampling cylinder slides up and down and the dynamic time between the horizontal plane , The manual positioning is rep...
