Description

Technical Field

[0001] The utility model relates to the field of soil detection, in particular to a soil heavy metal detection device. Background Art

[0002] In recent years, the discharge of industrial "three wastes" and the irrational use of chemical pesticides and fertilizers have led to frequent heavy metal contamination of the soil, seriously affecting the balanced development of the ecological environment and the normal growth of crops. Heavy metals have a small migration range in the soil and are difficult to be decomposed by microorganisms. They can enter the human body through the food chain, posing a threat to human health. Therefore, rapid detection of heavy metal content in the soil and timely feedback of heavy metal pollution information are very important for human health and agricultural production. However, when testing heavy metals in the soil using a handheld soil heavy metal detector, the tester is required to bend over and keep the sensor part of the handheld soil heavy metal detector close to the soil surface for about one minute. To ensure the accuracy of the test, multiple points of testing are generally performed. However, hand tremors during testing may affect the accuracy of the test, and bending over for a long time can damage the tester's body. To this end, we propose a soil heavy metal detection device.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figures 1 to 4The utility model provides a technical solution: a soil heavy metal detection device, including a detector body 1, a handle below the detector body 1 is wavy, the wavy handle not only improves the comfort of holding, but also increases the stability of the detector body 1 when the detector is aimed at the position to be detected. The upper and lower sides of the front end of the detector body 1 are respectively provided with retractable fixing parts 2, the retractable fixing parts 2 include two pairs of base plates 3 fixedly connected to the front end surface of the detector body 1, the base plate 3 is rotatably connected to the front end position of the detector body 1, two pairs of slot plates 5 are fixedly connected to the inside of the cover plate 4, the cover plate 4 is connected to a first rotating shaft 6, the first rotating shaft 6 passes through the base plate 3 and the slot plate 5, and the end of the base plate 3 away from the cover plate 4 is rotatably connected to the second rotating shaft 7 , both ends of the second rotating shaft 7 pass through the base plate 3 and are rotatably connected to the connecting rod 8, the other end of the connecting rod 8 is slidably connected to the slot plate 5, and the slot plate 5 is provided with a sliding groove 9. The connecting rods 8 are respectively fixedly connected with a sliding rod 10 through the sliding groove 9. The slot plates 5 are respectively attached to the outer side of the base plate 3, and the connecting rods 8 are respectively attached to the outer side of the slot plate 5. Through this design, the cover plate 4 can be prevented from being stuck in the process of opening and closing. The cover plate 4 is provided with a ground nail groove 11 near the connecting rod 8. The connecting rod 8 is fixedly connected with a ground nail 12 through the ground nail groove 11. The third rotating shaft 13 is rotatably connected between the slot plates 5. The third rotating shaft 13 is fixedly connected to the limit plate 14. The cover plate 4 is provided with an arc-shaped card block 15 at one end away from the first rotating shaft 6. The two ends of the card block 15 are fixedly connected with a protrusion 16. The detector body 1 is closed on the cover plate 4 The locking position is provided with an arc-shaped slot 17 corresponding to the block 15, and the block 15 and the slot 17 are transitionally matched. When in use, the inspector holds the detector body 1 toward the ground and uses the protrusion 16 on the side of the cover plate 4 to open the cover plate 4. When opened, the cover plate 4 drives the slot plate 5 to rotate around the first rotating shaft 6 rotatably connected to the base plate 3. One end of the connecting rod 8 slides in the slot 9 of the slot plate 5 through the slide rod 10, and the other end rotates in the base plate 3 through the second rotating shaft 7. Since the detector body 1 is downward, the limit plate 14 connected to the slot plate 5 is rotated to the bottom end of the oblique slot 9 through the third rotating shaft 13 under the action of gravity. When the cover plate 4 is unfolded, the slide rod 10 slides in the slot 9 and passes the limit plate 14, and the limit plate 14 at the bottom end of the oblique slot 9 can be moved by the slide rod 1 0 is easily pushed open so that the slide bar 10 reaches the bottom end of the slide groove 9, and resets after the slide bar 10 passes, clamping the slide bar 10 to limit it. When the slide bar 10 reaches the bottom end, the connecting rod 8 completes the support of the cover plate 4, and the ground nail 12 connected to the top end of the connecting rod 4 extends out of the ground nail groove 11 on the surface of the cover plate 4. At this time, the inspector aligns with the position to be inspected, embeds the detector with the ground nail 11 into the ground, and presses the detection switch without bending over to hold the detector body 1 stable, and the inspection can be completed. When the inspection is completed and needs to be put away, the inspector points the detector body 1 upwards. Under the action of gravity, the limit plate 14 releases the limit of the slide bar 10, and the inspector presses the cover plate 4 to make the slot plate 5 rotate along the first rotating shaft 6, driving the slide bar 10 to move to the top in the slot 9 of the slot plate 5.At the same time, the connecting rod 8 rotates along the second rotating shaft 7 and the top ground nail 12 moves upward in the ground nail groove, and finally the clamping block 15 is pressed into the clamping groove 17 to complete the closing of the retractable fixing member 2.
