Description
Technical Field
[0001] This utility model relates to the field of heavy metal detectors, and in particular to a portable on-site heavy metal detector for agricultural products. Background Technology
[0002] Agricultural products refer to primary products derived from agriculture, namely plants, animals, microorganisms and their products obtained directly from agricultural activities. Heavy metals refer to metallic elements with a density greater than 4.5 g / cm³. Common heavy metals that are harmful to agricultural products and the environment include metal elements such as lead, cadmium and mercury. These heavy metals can be absorbed by crops through soil, water sources, air and other means, and accumulate in the food chain, or enter rivers and lakes through runoff, threatening aquatic ecosystems. Therefore, heavy metal pollution is an important hidden danger to the quality and safety of agricultural products.
[0003] In the prior art, patent application document "CN219915051U" discloses an "Outdoor Agricultural Product Heavy Metal Rapid Detection Instrument"; it includes a box body, a blade holder detachably installed at the upper end of the box body, a filter screen fixedly connected to the lower end of the blade holder, a box cover slidably installed at the upper end of the box body, an extrusion plate fixedly connected to the lower end of the box cover, and an extrusion screw rotatably installed at the rear end of the box body, the extrusion screw being threadedly connected to the box cover. This utility model has a novel structure, ingenious design, and is simple and convenient to operate, effectively avoiding the problem of human body being contaminated with colorimetric reagents.
[0004] The aforementioned "rapid outdoor heavy metal detector for agricultural products" still has some drawbacks. For example, existing heavy metal detectors for agricultural products break down agricultural products during use and test the liquid produced after breaking them down for heavy metals. After testing the liquid, manual cleaning is required, which is inefficient and the testing equipment is small and cumbersome. To address these issues, a portable on-site heavy metal detector for agricultural products is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a portable on-site heavy metal detector for agricultural products.

[0013] Compared with the prior art, the beneficial effects of this utility model include: The cleaning solution in the storage tank is driven by a water pump and drawn into the distribution plate through the water pipe. It is then sprayed out through the outlet nozzles on both sides of the distribution plate. The high-speed cleaning solution is sprayed through the outlet nozzles to the inner wall of the detection cylinder, which quickly cleans the inner wall of the detection cylinder and washes away the residual agricultural product liquid. The rotation of the detection cylinder increases the cleaning area with the outlet nozzles, and the entire inner wall of the detection cylinder is rinsed and cleaned.

The meshing of the first and second helical gear discs causes the bottom connecting rod to rotate synchronously as the first disc rotates. This rotating bottom connecting rod then drives the agitator blades to stir along the inside of the storage tank, reducing sedimentation of the cleaning solution and improving its effectiveness.

[0031] The specific usage and function of this embodiment are as follows: First, the agricultural products to be tested are placed into the testing chamber 1 along the feeding cylinder 5. After the main motor 603 is started, it drives the stirring rod 604 to rotate. The rotating stirring rod 604 will drive the crushing blade 605 to rotate, crushing the agricultural products in the top protective cylinder 606 and the feeding cylinder 5. The liquid generated after crushing will flow into the inner side of the testing cylinder 702 along the top drain trough 607. The bottom protective cylinder 602 protects the main motor 603, reducing the contact between the liquid and the main motor 603 and improving the protection of the main motor 603. After the liquid enters the detection cylinder 702, it comes into contact with the detection probe 4. Under the control of the detection machine 3, the liquid in the detection cylinder 702 is tested for heavy metals. After the test is completed, the electric push rod 707 starts to push the side connecting plate 706 down along the inner side of the connecting frame 708. The descent of the side connecting plate 706 will simultaneously drive the bottom connecting plate 705 and the blocking plate 704 down. After the multiple blocking plates 704 descend along the inner side of the bottom drain trough 703, the bottom drain trough 703 will be opened. At this time, the liquid in the detection cylinder 702 will flow into the liquid receiving cylinder 10 along the bottom drain trough 703 and be discharged along the drain pipe 11. By activating the water pump 802, the cleaning solution in the storage tank 801 is drawn into the distribution plate 804 through the water pipe 803 and sprayed out through the outlet nozzles 805 on both sides of the distribution plate 804. The high-speed cleaning solution sprayed through the outlet nozzles 805 reaches the inner wall of the detection cylinder 702, quickly cleaning the inner wall of the detection cylinder 702 and rinsing away any residual agricultural product liquid. Simultaneously, the side motor 806 is activated, driving the top gear disk 807 to rotate. The rotating top gear disk 807 will drive... The transmission rod 808 rotates synchronously. Utilizing the meshing between the transmission rod 808 and the side gear plate 809, the transmission rod 808 rotates, driving the detection cylinder 702 inside the side gear plate 809 to rotate. The rotating detection cylinder 702 slides along the inner side of the sliding rail 8010, improving the stability of the rotation of the detection cylinder 702. After the detection cylinder 702 rotates, it increases the cleaning area with the liquid outlet nozzle 805, rinsing and cleaning the entire inner wall of the detection cylinder 702. Waste liquid is discharged along the bottom drain trough 703, eliminating the need for operator cleaning and improving portability during the detection process. Simultaneously, the external motor 901 starts the fixed rod 902 to rotate. The rotating fixed rod 902 drives the transmission fan 903 to rotate. With the connection ring 904 for fixation, the transmission fan 903 on one side of the test box 1 generates wind when it rotates and blows it towards the inside of the test box 1, improving the airflow inside the test box 1 and reducing the temperature stability inside the test box 1 when working in high outdoor temperatures. At the same time, the rotating fixed rod 902 drives the first helical gear disk 905 to rotate. With the meshing of the first helical gear disk 905 and the second helical gear disk 906, the rotation of the first helical gear disk 905 will synchronously drive the bottom connecting rod 907 to rotate. The rotating bottom connecting rod 907 will drive the stirring blade 908 to stir along the inside of the liquid storage tank 801, reducing the precipitation of the cleaning fluid and improving the effectiveness of the cleaning fluid in the liquid storage tank 801.
