Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a rapid detection kit for heavy metals in soil. Background Technology

[0002] With the rapid development of industrialization and agricultural activities, soil heavy metal pollution has become increasingly serious, posing a threat to the ecological environment and human health. Traditional methods for detecting heavy metals in soil (such as atomic absorption spectrometry and inductively coupled plasma mass spectrometry) are highly accurate, but they suffer from problems such as expensive equipment, complex operation, and long detection cycles, making it difficult to meet the needs of rapid on-site detection. Utility Model Content

[0003] The purpose of this invention is to provide a soil heavy metal rapid detection kit that is reasonably designed and easy to use, which can effectively solve the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a processing box, a detection box, and a detector; the detection box is fixed to one side of the processing box, and a detector is inserted into and fixed to one side of the lower side wall of the detection box; it also includes: The filter mechanism is located on the upper side inside the processing box, and a guide hopper is located on the lower side of the filter mechanism. A feeding mechanism is located on the lower side of the guide hopper, and the other side of the feeding mechanism is located inside the detection box. A mixing chamber is located inside the side wall of the detection chamber away from the processing chamber. The discharge end of the feeding mechanism is connected to the inlet of the mixing chamber, and the outlet of the mixing chamber is connected to the detector through a pipe. The stirring rods consist of two rods, which are symmetrically connected to the inside of the testing box via bearings. The lower end of the stirring rod is connected to the upper side wall of the mixing box via bearings and is placed inside the mixing box. Several stirring blades on the stirring rods are suspended on the lower side inside the mixing box. The stirring motor is fixed on the outer top wall of the test box. The output shaft of the stirring motor is connected to the top of one of the stirring rods. The two stirring rods are equipped with meshing linkage gears, which are located inside the top wall of the test box. The above technical solution involves pouring sampled soil into a treatment tank and filtering it through a filtration mechanism. The filtered soil is then fed into a mixing tank via a feeding mechanism. The treatment agent is then poured into the mixing tank, and the stirring motor is activated. The stirring motor drives a connected stirring rod to rotate, which in turn drives another stirring rod via a linkage gear. The stirring blades at the bottom of the two stirring rods mix the soil and treatment agent. The engagement of the two linkage gears allows the two stirring rods to rotate in opposite directions, improving the thoroughness of the mixing. After thorough mixing, the liquid enters the detector through a pipeline, allowing for soil detection and achieving rapid testing.

[0005] As a further improvement of this utility model, the filtration mechanism includes: The filter box is located on the upper side inside the processing box. Connecting plates are fixed on both the left and right sides of the lower side wall of the filter box.

Both ends of the linkage rod are connected to the shafts on the drive discs on both sides via synchronous wheel transmission components. A drive motor is fixed to one end of the linkage rod. The drive motor is fixed to one side wall of the processing box and embedded in the detection box. Using the above technical solution, the soil poured into the treatment box falls onto the filter box. The drive motor is started, and the drive motor drives the linkage rod to rotate. The linkage rod drives the drive disc to rotate through the synchronous wheel transmission assembly. The drive disc drives the connecting plate to move up and down through the actuating rod on its other side wall. The connecting plate drives the filter box to move up and down, and the soil is filtered through the filter box.
