Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, in particular to a rapid sampling device for enzyme activity detection. Background Art
[0002] The rocks on the surface of the earth are weathered and gradually broken down into loose mineral particles of varying sizes (called parent material). Soil is formed and evolved under the combined effects of multiple soil-forming factors such as parent material, climate, biology, topography, and time. The composition of soil is very complex. Generally speaking, it is composed of three phases: solid, liquid, and gas, including minerals, organic matter produced by the decomposition of plant and animal residues, water, and air. Soil environmental monitoring refers to determining the environmental quality (or degree of pollution) and its changing trends by measuring the representative values of factors affecting soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical contents such as sampling points, sample preparation, analysis methods, result characterization, data statistics, and quality evaluation.
[0003] When conducting soil testing, the sampling tube is often an integrated structure. When sampling the soil, a small amount of soil often gets stuck after the sampling is completed, thereby blocking the outer protective tube and making it inconvenient for the next sampling.
[0004] Therefore, in order to solve the above problems, a rapid sampling device for enzyme activity detection is proposed. Utility Model Content
[0005] The utility model aims to provide a rapid sampling device for enzyme activity detection, comprising an outer protective tube, wherein the front end of the outer protective tube is threadedly connected to the front connecting head, the rear end of the outer protective tube is threadedly connected to the rear connecting cover, a sampling tube placement cavity is provided inside the outer protective tube, a sampling tube is provided inside the sampling tube placement cavity, the rear end of the sampling tube is connected to a push rod, the rear end of the push rod passes through the rear connecting cover, and extends to the outside of the rear connecting cover and is connected to a push handle, connecting rods are respectively provided on both sides of the part of the push rod located inside the sampling tube, a sliding block is provided on the side of the connecting rod away from the push rod, the sliding block is slidably provided in a sliding groove provided on the side walls on both sides of the rear end of the outer protective tube, a plurality of sampling grooves are provided on both sides above the sampling tube, and the front end of the sampling tube is connected to a conical head.
[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0007] The utility model is provided with a pushing handle, a pushing rod, a sampling tube, a sampling groove and a conical head. The pushing handle pushes the pushing rod, and the pushing rod pushes the sampling tube to extend out of the sampling hole. The setting of the conical head can facilitate the sampling tube to penetrate into the soil, and then the soil enters the sampling groove, which is convenient for sampling.
[0008] The utility model provides connecting rods on both sides of the push rod, and a sliding block connected to one side of the connecting rod slides in a sliding groove, thereby improving the stability during pushing.
[0009] The utility model provides positioning nails penetrating through both sides of the connection plate, and the positioning nails can facilitate positioning of the outer protective tube on the soil, thereby facilitating sampling.
[0010] The utility model threadably connects the front connector and the rear connector cover to the front and rear ends of the outer protective tube, so that the front connector and the rear connector cover can be easily disassembled, and then the sampling tube can be taken out, so as to clean the inside of the sampling tube and the outer protective tube.
