Description

Technical Field

[0001] The invention relates to the technical field of heavy metal detectors, in particular to a heavy metal detector which is easy to operate. Background Art

[0002] Heavy metals are the most prominent among inorganic pollutants in soil. This is mainly because heavy metals cannot be decomposed by soil microorganisms, but are easily accumulated and converted into more toxic methyl compounds. Some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. The main heavy metal elements that pollute soil are mercury, cadmium, lead, copper, chromium, nickel, zinc, etc. These heavy metal elements cannot be degraded by microorganisms and are easily enriched, thus causing soil heavy metal pollution;

[0003] In the prior art, heavy metal pollution detection in soil is mainly carried out by means of handheld metal detectors, such as a soil heavy metal detector with publication number CN218546739U, which can facilitate workers to perform detection operations. However, in actual use, when the soil surface is uneven or there are garbage or foreign matter, the detection results will be affected. Moreover, when there are foreign matter such as gravel and other foreign matter on the soil, the detector may be damaged due to direct contact and friction with the gravel and the detector. Therefore, in view of the above problems, a heavy metal detector that is easy to operate is designed to better meet the actual use needs. Summary of the invention

The specific contents are as follows:

[0016] 1. This easy-to-operate heavy metal detector, when testing, inserts the scraper 1cm-2cm under the soil, and applies force to the mounting rod, so that the bottom plate is forced to move, and the transmission effect of the connecting rod can make the movable plate move, thereby driving the scraper to move. The movement of the scraper can scrape the surface of the soil, which can not only ensure the flatness of the soil under the heavy metal detector body, but also prevent foreign matter and gravel on the soil surface from damaging the device and affecting the accuracy of the device's detection data;

[0017] 2. The easy-to-operate heavy metal detector, the baffle, when the bottom plate moves, simultaneously drives the movable rod and the fixed rod to move, thereby driving the top rod, the vertical rod and the protective cover to move, and cooperating with the convex shaft; the sliding action between the inclined plate can make the baffle move outward under force, thereby automatically releasing the seal of the heavy metal detector body, making it convenient for the heavy metal detector body to contact the soil for detection.

A movable plate 507 is symmetrically connected to the cross bar 506 in the front and rear directions. The movable plate 507 and the cross bar 506 are slidably connected. A scraper 508 is fixed to the lower end surface of the movable plate 507, and the lower end surface of the scraper 508 is 1cm-2cm lower than the lower end surface of the base plate 504. The movable plate 507 is rotatably connected to one end of a connecting rod 509, and the other end of the connecting rod 509 is rotatably connected to the mounting rod 1. When the base plate 504 contacts the ground and is subjected to force so that the distance between the base plate 504 and the mounting rod 1 is reduced, the movable plate 507 can be subjected to force to slide on the cross bar 506 through the transmission action of the connecting rod 509, thereby driving the scraper 508 to move, and the movement of the scraper 508 can achieve soil leveling and foreign matter cleaning.

[0028] An anti-slip sleeve 101 is installed on the mounting rod 1, and a control button 102 is installed on the mounting rod 1 for controlling the heavy metal detector body 3; a built-in battery is arranged in the heavy metal detector body 3, and the heavy metal detector body 3 can detect elements such as Al, S, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Y, Zr, Nb, Mo, Ag, Cd, Sn, Sb, I, Ba, Eu, Yb, Lu, Hf, Hg, Pb and Bi, and the heavy metal detector body 3 is an X-ray fluorescence soil heavy metal analyzer; the touch screen storage mechanism 4 includes a storage box 401, a first magnetic Iron 402, second magnet 403, iron plate 404, dial plate 405 and touch screen body 406, storage box 401 is fixed on mounting rod 1, and first magnet 402 is fixed symmetrically front and back on the lower inner end of storage box 401, and second magnet 403 is fixed symmetrically front and back on the upper inner end of storage box 401, and iron plate 404 is slidably connected in storage box 401, and magnetic attraction structure is formed between iron plate 404 and first magnet 402 or second magnet 403; dial plate 405 is fixed on the right end face of iron plate 404, and dial plate 405 penetrates storage box 401 and can slide up and down; touch screen body 406 is fixed on the upper end face of iron plate 404, and touch screen body 406 and storage box 401 are slidably connected;

[0029] When using this easy-to-use heavy metal detector, Figure 1-Figure 7As shown, at this time, the entire device is in the storage device, and by pushing the dial plate 405, the iron plate 404 can be forced to separate from the first magnet 402, so that the iron plate 404 and the touch screen body 406 are forced to move upward until the iron plate 404 moves up to be adsorbed and fixed with the second magnet 403, thereby realizing the expansion of the touch screen body 406. According to the above principle, after the subsequent use of the device is completed, the touch screen body 406 can be stored by pressing the dial plate 405. After the touch screen body 406 is expanded, the device can be easily taken out by holding the anti-slip cover 101. When testing the soil, by applying a downward force to the installation rod 1, the bottom plate 504 and the installation frame 505 can be brought into contact with the ground, and the scraper 508 is inserted into the ground by 1cm-2cm, and by applying a force to the installation rod 1, The bottom plate 504 is forced to move upward, so that the distance between the bottom plate 504 and the lower end surface of the mounting rod 1 is reduced, so that the connecting rod 509 is forced to rotate, and the movable plate 507 can be forced to move to both sides through the transmission effect of the connecting rod 509, and the sliding guide effect between the movable plate 507 and the cross bar 506 can ensure the stability of the movement of the movable plate 507. When the movable plate 507 moves, the scraper 508 is driven to move at the same time. Through the action of the scraper 508, the soil surface can be scraped and cleaned, which can not only ensure the surface of the detected soil position is flat, but also clean up the gravel and foreign matter on the soil surface, so as to avoid the gravel and foreign matter from affecting the detection result of the heavy metal detector body 3 or the gravel from damaging the detection head of the heavy metal detector body 3, thereby ensuring the service life of the heavy metal detector body 3;

[0030] The protective structure 6 includes a protective cover 601, a vertical rod 602, a top rod 603, a fixed frame 604, a baffle 605, a connecting frame 606, a convex shaft 607, an inclined plate 608, a sliding rod 609 and a second spring 610. The protective cover 601 is slidably connected to the outside of the heavy metal detector body 3, and the vertical rod 602 is symmetrically fixed to the protective cover 601, and the top rod 603 is fixed to the upper end of the vertical rod 602. At the same time, the top rod 603 and the fixed rod 502 are fixed to each other, and the fixing frame 604 is symmetrically fixed to the protective cover 601; the baffle 605 is symmetrically slidably connected to the protective cover 601, and the baffle 605 is fixed with a The outer side of the protective cover 601 is connected to a frame 606, and a convex shaft 607 is fixed on the frame 606, and the convex shaft 607 is slidably connected to the inclined plate 608; the widest position width of the inclined plate 608 is greater than the diameter of the heavy metal detector body 3, and the height of the inclined surface at the lower end of the inclined plate 608 is greater than the distance between the upper end surface of the baffle 605 and the lower end surface of the heavy metal detector body 3; a slide bar 609 is also fixed on the frame 606, and the slide bar 609 is slidably connected to the fixed frame 604, and one end of the second spring 610 is also fixed on the frame 606, and the other end of the second spring 610 is fixed to the fixed frame 604;

[0031] During the testing process, Figure 1-Figure 7 As shown, when the bottom plate 504 is forced to move upward, the movable rod 501 and the fixed rod 502 slide upward synchronously, thereby driving the top rod 603, the vertical rod 602 and the protective cover 601 to move upward synchronously. When the protective cover 601 moves, the baffle 605, the connecting frame 606 and the convex shaft 607 are synchronously driven to move upward. With the sliding action between the convex shaft 607 and the inclined surface of the inclined plate 608, the connecting frame 606 can be forced to move, so that the baffle 605 is forced to slide toward the outside of the protective cover 601. With the sliding guiding action between the sliding rod 609 and the fixed frame 604, the stability of the movement of the baffle 605 can be guaranteed. When the convex shaft 607 slides to the widest position of the inclined plate 608, the baffle 605 is fully opened at this time. Since the widest position width on the inclined plate 608 is greater than the diameter of the heavy metal detector body 3, it can be ensured that the distance between the two baffles 605 is greater than the diameter of the heavy metal detector body 3 at this time, thereby releasing the sealing protection effect on the detection head of the heavy metal detector body 3. And because the height of the inclined surface at the lower end of the inclined plate 608 is greater than the distance between the upper end surface of the baffle 605 and the lower end surface of the heavy metal detector body 3, it can be ensured that when the baffle 605 is fully opened, the lower end surface of the heavy metal detector body 3 does not contact the baffle 605, thereby avoiding the device from getting stuck, and when the protective cover 601 continues to move upward, the detection head of the heavy metal detector body 3 can be separated from the protective cover 601 and contact the soil, and then the heavy metal detector body 3 can be started by pressing the control button 102 to realize the detection of the soil. The detected data is displayed on the touch screen body 406 for the staff to view. After the detection is completed, according to the above principle, in conjunction with the action of the second spring 610 and the first spring 503, the protective cover 601 and the baffle 605 can be automatically reset to seal and protect the detection head of the heavy metal detector body 3, thereby avoiding damage to the detection head of the heavy metal detector body 3, thereby effectively ensuring the service life of the device. This is the working principle of the easy-to-operate heavy metal detector.
