[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] Embodiment: This embodiment provides a rapid detection device for heavy metals in cultivated soil. Figure 1-6 Specifically, it includes a shell 1, which is in a rectangular frame shape. A first mounting plate 2 is fixedly arranged inside the shell 1, and a feeding port 3 is fixedly arranged at the upper end of the first mounting plate 2. A second mounting plate 4 is fixedly arranged on the inner side of the shell 1, and a third mounting plate 5 is fixedly arranged at the other end of the second mounting plate 4. A circular block 8 is rotated inside the third mounting plate 5, and a rotating rod 7 is fixedly arranged at the upper end of the circular block 8. The lower surface of the rotating rod 7 is arranged at the edge of the upper surface of the circular block 8. A rotating block 6 is fixedly arranged at the upper end of the rotating rod 7. The diameter of the rotating block 6 is smaller than the diameter of the first mounting plate 2. A gear ring 9 is fixedly arranged at the upper end of the circular block 8. A first motor 10 is fixedly arranged inside the second mounting plate 4, and a gear 11 is fixedly arranged at the output end of the first motor 10, and the gear 11 is meshed with the gear ring 9.
[0026] The first motor 10 drives the gear 11 to rotate, the gear 11 drives the gear ring 9 to rotate, the gear ring 9 drives the circular block 8, the circular block 8 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the rotating block 6 to rotate. Since the lower surface of the rotating rod 7 is arranged at the edge of the upper surface of the circular block 8, when the circular block 8 drives the rotating rod 7 to rotate, the rotating block 6 collides with the first mounting plate 2, and the staff puts the dry soil sample into the shell 1 from the feed port 3. The soil sample is squeezed through the collision between the rotating block 6 and the first mounting plate 2. The staff does not need to manually crush and grind the soil sample, which saves time and effort. The squeezed soil sample falls from between the first mounting plate 2 and the rotating block 6. Since the diameter of the third mounting plate 5 is smaller than the diameter of the rotating block 6, the falling soil sample will not fall on the upper end of the third mounting plate 5.
[0027] In the specific implementation process, Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a box body 12 is fixedly provided at the lower end of the housing 1, and the box body 12 is in a rectangular box shape. A filter plate 14 is arranged in the box body 12, and a pair of short rods 13 are rotated at both ends of the filter plate 14, and the upper ends of the short rods 13 are rotated on the inner side of the box body 12. A first discharge port 15 is fixedly provided on one side of the filter plate 14, and a plurality of circular holes are opened at the upper end of the filter plate 14. A fourth mounting plate 16 is fixedly provided on the other side of the box body 12, and a second motor 17 is fixedly provided in the fourth mounting plate 16. The output end of the second motor 17 is fixedly provided. A disc 18 is fixedly provided, a connecting rod 19 is rotated at one end of the disc 18, one side of the connecting rod 19 is rotated at the other side of the filter plate 14, a round rod 27 is fixedly provided at one end of the connecting rod 19, a long rod 28 is rotated at one end of the round rod 27, and the left end of the long rod 28 is rotated at one end of the filter plate 14, two chute grooves are provided on one side of the box body 12, sliders 20 are slidably provided in both chute grooves, a collecting box 21 is fixedly provided between the two sliders 20, and a second discharge port 22 is fixedly provided on the other side of the collecting box 21;
[0028] The filter plate 14 and the collection box 21 are both tiltedly arranged in the box body 12, and the collection box 21 is located below the filter plate 14. A cover plate 25 is rotated on one side of the box body 12, and a handle is fixedly arranged at the lower end of the cover plate 25. A rectangular hole is opened on one side of the cover plate 25, and the first discharge port 15 is located in the rectangular hole. An inclined plate 26 is fixedly arranged on one side of the cover plate 25, and the other side of the inclined plate 26 is attached to one side of the first discharge port 15. A rectangular groove is opened on the other side of the box body 12, and the second discharge port 22 is located in the rectangular groove. A detector body 23 is arranged on the other side of the box body 12, and a tray 24 is arranged on the upper end of the detector body 23, and one side of the tray 24 is attached to the other side of the box body 12;
[0029] The prepared collection frame is placed on one side of the cover 25, and the second motor 17 drives the disc 18 to rotate, and the disc 18 drives the connecting rod 19 to make the filter plate 14 reciprocate. By setting the short rod 13, the filter plate 14 vibrates in the box body 12. Since the filter plate 14 is tilted in the box body 12, the large pieces of soil samples at the upper end of the filter plate 14 slide into the collection frame from the first discharge port 15, and the finely divided soil samples are sieved into the collection box 21 through a number of circular holes. Since the collection box 21 is tilted in the box body 12, the soil sample at the upper end of the collection box 21 slides into the tray 24 through the second discharge port 22, so that the soil sample is quickly prepared, thereby allowing the heavy metals in the soil to be quickly detected. When the collection box 21 needs to be cleaned, the cover 25 is opened, the collection box 21 is pulled out of the shell 1, and the collection box 21 is cleaned for easy use.
[0030] Specifically, the working principle and operation method of the utility model are as follows:
[0031] Step 1: The first motor 10 drives the gear 11 to rotate, the gear 11 drives the gear ring 9 to rotate, the gear ring 9 drives the circular block 8, the circular block 8 drives the rotating rod 7, the rotating rod 7 drives the rotating block 6 to rotate, and the staff puts the dry soil sample into the housing 1 from the feed port 3. Under the rotation of the first mounting plate 2 and the rotating block 6, the soil sample is broken and falls to the upper end of the filter plate 14;
[0032] Step 2: Place the prepared collection frame on one side of the cover plate 25, the second motor 17 drives the disc 18 to rotate, and the disc 18 drives the connecting rod 19, so that the filter plate 14 reciprocates, causing the filter plate 14 to vibrate, and the large pieces of soil samples slide into the collection frame from the first discharge port 15, and the finely crushed soil samples are sieved into the collection box 21 and slide into the upper end of the tray 24 through the second discharge port 22;
[0033] Step three, when the collection box 21 needs to be cleaned, the cover plate 25 is opened, the collection box 21 is pulled out of the housing 1, and the collection box 21 is cleaned by a staff.
[0034] The utility model solves the problem of manual crushing and grinding of soil samples and manual screening when heavy metal detection is carried out on the soil through the coordinated use of various components. By setting a rotating block, there is no need for workers to manually crush and grind the soil samples, and by setting a filter plate, the soil samples are automatically screened, which is easy to use.
[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
