Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soil fertilizer sampling, and in particular relates to sample extraction equipment for fertilizer residue detection. Background Art
[0002] Fertilizer residue refers to the fertilizer substances remaining in the soil that have not been completely absorbed and utilized by crops after the application of fertilizers. Fertilizer residue will have a certain impact on soil quality to a certain extent, such as promoting soil acidification and causing fruit to change taste. However, white particles do not necessarily have a negative impact on crops. The specific impact needs to be judged based on the soil environment, crop type and other conditions. Therefore, it is necessary to extract samples of fertilizer residues through sample extraction equipment for subsequent testing to determine whether it has an impact on crops.
[0003] However, after the sampling is completed, the sampling tube of the existing sample extraction equipment generally directly pushes out the soil inside the sampling tube. The pushed out soil is easy to mix together, resulting in the inability to perform stratified detection, which in turn affects the detection accuracy. In addition, the sampling tube is mostly set up in an integrated manner. After the sampling tube samples the soil once, the sampling tube is not convenient to clean, and the cleaning efficiency and quality are poor, which is easy to affect the next soil sampling. For this reason, we propose a sample extraction device for fertilizer residue detection. Utility Model Content

When it is necessary to extract samples of fertilizer residues in the soil, first rotate the first rotating threaded rod 303 and the second rotating threaded rod 304. Through the setting of opposite threads on the surfaces of the first rotating threaded rod 303 and the second rotating threaded rod 304, when the first rotating threaded rod 303 and the second rotating threaded rod 304 rotate, the two moving blocks 305 can drive the two semicircular sampling tubes 306 to approach each other, so that the two semicircular sampling tubes 306 are spliced together, and then the lifting threaded rod 301 is rotated, so that the lifting threaded rod 301 drives the turntable 302 to rotate and descend, and then the turntable 302 drives the two semicircular sampling tubes 306 to rotate and descend, so that the two semicircular sampling tubes 306 extract the soil.
[0020] In this embodiment, preferably, a fixing mechanism 4 is provided at the lower end of the mounting frame 1, and the fixing mechanism 4 includes a fixing rod 401, and two fixing rods 401 are symmetrically provided on the left and right sides, and the two fixing rods 401 are respectively arranged inside the lower ends of the left and right sides of the mounting frame 1, and a rotating base 402 is rotatably installed on the circumferential surface of the two fixing rods 401, and a telescopic spring 403 is arranged inside the right side of the right rotating base 402, and a plug-in plate 404 is arranged at the right end of the telescopic spring 403, and a toggle block is arranged on the upper surface of the plug-in plate 404, and a plug-in groove 405 matching the plug-in plate 404 is opened inside the left end of the left rotating base 402, and ground nails are arranged on the lower surfaces of the two rotating bases 402.

At this time, a sample collection box is placed directly below the semicircular sampling tube 306, and then the first rotating threaded rod 303 and the second rotating threaded rod 304 are rotated in the opposite direction to separate the two semicircular sampling tubes 306. The soil inside will fall into the collection box in a straight line, and the soil will not be mixed. Then, the soil at different depths can be tested to facilitate understanding of the residues in the soil at different depths. At the same time, the separation of the two semicircular sampling tubes 306 is convenient for cleaning the inside of the semicircular sampling tube 306, thereby improving the subsequent sampling quality.
