Technical Field

[0001] The present invention relates to the technical field of soil sampling, and in particular to a soil sampling device for analyzing soil pollution. Background Art

[0002] Soil pollution refers to the phenomenon that pollutants generated by human activities enter the soil and accumulate to a certain extent, causing soil quality to deteriorate and then causing certain indicators of crops to exceed national standards. At present, sampling is often required during soil analysis, and soil sampling equipment is required during sampling.

[0003] The soil sampling equipment currently on the market usually requires the user to press the device with great effort, which greatly increases the difficulty of sampling. It is also time-consuming to take out the sample soil. In addition, when sampling, it is not convenient to sample the soil at different depths according to the needs of the staff, and the use is relatively simple. Summary of the invention

[0004] The purpose of the present invention is to provide a soil sampling device for analyzing soil pollution in order to solve the problems raised in the above-mentioned background technology in view of the defects of the prior art.

The base plate is limited to the lower end of the sampling portion by the limit pin, the support portion is installed on the base plate, the pushing portion is placed on the inner circle of the support portion, the sampling block is detachably and slidably arranged on the pushing portion, the threaded barrel is rotatably installed at the bottom of the base plate, the electric cylinder 2 is placed inside the threaded barrel, and its output end passes through the base plate through the stud and is threadedly connected to the pushing portion.

[0006] By adopting the above technical solution, sampling can be convenient and fast, and soil at different depths can be sampled.

[0007] The bracket is also provided with a limiting axis for limiting the extension arm.

[0008] By adopting the above technical solution, it is convenient to position the extension arm when not in use.

[0009] The sampling part is also provided with a pressing part for pushing out the sample soil.

[0010] By adopting the above technical solution, it is convenient to push out the sample soil.

[0011] The outer wall of the sampling part is provided with three notches, and the sampling blocks are also provided with three notches. The three sampling blocks can be arranged correspondingly to the notches one by one.

[0012] By adopting the above technical solution, soil samples are taken at multiple locations at different depths.

[0013] The length of the stud is at least three times greater than the thickness of the base plate, and the stud is rotationally connected to the output end of the electric cylinder.

[0014] By adopting the above technical solution, it is convenient to connect the stud with the pushing part.

[0015] The pressing part is composed of a connecting plate and a pressing rod as a whole. The connecting plate is arranged inside the sampling part and is matched with the diameter of the inner wall of the sampling part. The pressing rod is arranged to pass through the top of the sampling part.

[0016] By adopting the above technical solution, it is convenient to push out the sample soil.

[0017] A positioning groove is provided at the bottom of the pushing part, and a positioning block is provided on the bottom plate to limit the angular position of the pushing part on the bottom plate. The supporting part is used to limit the height of the sampling block so that the three sampling blocks correspond to the three notches of the sampling part one by one and can pass through the notches.

[0018] By adopting the above technical solution, it is ensured that the sampling block can be normally pushed out of the notch of the sampling part to carry out sampling.

[0019] A groove is provided on one side of the extension arm, and a convex key is provided at the inner ring of the gear ring. The convex key of the gear ring is embedded in the groove of the extension arm, so that the gear ring and the extension arm are driven to rotate synchronously.

[0021] The beneficial effects of the soil sampling device for analyzing soil pollution of the present invention are: 1. The second electric cylinder can be controlled to push the pushing part upward, and the pushing part pushes the sampling block out of the slot to sample the soil at a predetermined height. After the sampling block is sampled, the second electric cylinder can be controlled to pull the pushing part downward. At this time, the sampling block moves along the slide groove on the outer wall of the pushing part until the sampling block is completely retracted into the sampling part. The sampling part can be pulled upward by holding the handle to separate from the sampling port. After removing the bottom plate, the pushing part and the sampling block can be taken out and collected, which is convenient for collecting soil samples at different depths. 2. The ring sleeve and the support rod are rotatably connected. At this time, the angle of the sampling part can be swung by rotating the ring sleeve, so that the sampling part can be swung up to an inclined state, so as to adjust the angular position of the sampling part and facilitate the removal of the sample soil in the sampling part.

[0022] 3. By manually pressing the sampling part downward, the downward moving position of the sampling part can be controlled, and when using the auxiliary sampling component, it can be sensed in real time whether the threaded barrel has touched the ground, thereby stopping the downward movement of the sampling part, making it convenient for the subsequent auxiliary sampling component to perform sampling.

The base plate 16 is limited to the lower end of the sampling portion 13 by the limit pin 20. The support portion 17 is installed on the base plate 16. The push portion 18 is placed at the inner circle of the support portion 17. The sampling block 19 is detachably slidably arranged on the push portion 18. A positioning groove is provided at the bottom of the push portion 18. A positioning block is provided on the base plate 16 to limit the angular position of the push portion 18 on the base plate 16. The support portion 17 is used to limit the height of the sampling block 19 so that the three sampling blocks 19 correspond to the three notches 1301 of the sampling portion 13 one by one and can pass through the notches 1301. The threaded barrel 15 is rotatably installed at the bottom of the base plate 16. The electric cylinder 21 is placed inside the threaded barrel 15. Its output end passes through the base plate 16 through the stud 22 and is threadedly connected to the push portion 18.

[0027] The bracket 1 is also provided with a limiting shaft 12 for limiting the extension arm 10; a thread groove is provided on one side of the extension arm 10, and when the device is not in use, the limiting shaft 12 can be rotated in the thread groove to prevent the extension arm 10 and the sampling part 13 from shaking.

[0028] The length of the stud 22 is set to be at least three times greater than the thickness of the base plate 16, and the stud 22 is rotatably connected to the output end of the electric cylinder 21; after the stud 22 passes through the base plate 16, the stud 22 can be rotated to connect the stud 22 to the bottom of the pushing portion 18, so that the pushing portion 18 can be driven up and down by the electric cylinder 21 to control the sampling block 19 to enter and exit the slot 1301.

[0029] The pressing part 14 is composed of a connecting plate and a pressing rod. The connecting plate is arranged inside the sampling part 13 and is matched with the inner wall diameter of the sampling part 13. The pressing rod is arranged to pass through the top of the sampling part 13. After the sampling part 13 completes collecting the sample soil, the sample soil can be pushed out of the sampling part 13 by pushing the pressing part 14.

[0030] During the initial sampling, it is not necessary to install the bottom plate 16, the supporting part 17, the pushing part 18, the sampling block 19, and the limiting pin 20 on the sampling part 13. It is only necessary to use the sampling part 13 and the pressing part 14 set on the upper end thereof to place the device at the position to be sampled, and then adjust the tooth direction of the gear ring 9, drive the electric cylinder 12 to slowly push the motor 5 and the gear 6 at the carrier frame 4, so that the gear 6 is meshed with the gear ring 9, and then rotate the limiting shaft 12 to separate it from the extension arm 10. A groove is provided on one side of the extension arm 10, and a convex key is provided on the inner ring of the gear ring 9. The convex key of the gear ring 9 is embedded in the groove of the extension arm 10, so that the gear ring 9 and the extension arm 10 are driven to rotate synchronously. At this time, the handle 11 can be held to start the motor 5 to drive the gear 6, and the gear 6 drives the gear The ring 9 rotates, and the gear ring 9 drives the sampling part 13 to rotate synchronously through the extension arm 10, and moves the extension arm 10 downward, passing through the circular hole at the bottom of the bracket 1, so that the bottom of the sampling part 13 contacts the ground. The sampling part 13 can drill into the ground through the teeth at its bottom and take samples. After the sampling is completed, the electric cylinder 2 is driven to pull the carrier 4 back to its original position, and the extension arm 10 is lifted upward by the hand handle 11 until the sampling part 13 is separated from the ground. Because the ring sleeve 8 and the support rod 7 are rotatably connected, the sampling part 13 can be swung to an angle by rotating the ring sleeve 8, so that the sampling part 13 is tilted. The sampling part 13 is also provided with a pressing part 14 for pushing out the sample soil; the pressing part 14 can be pressed to push out the sample soil collected by the sampling part 13, and collect it through an external collection box; In order to better collect soil samples at different depths, the pushing part 18 is placed on the inner circle of the supporting part 17. (It should be noted that, in order to ensure that the sampling block 19 corresponds to the notch 1301 one by one, so that the sampling block 19 can pass through the notch 1301, a positioning groove is set at the bottom of the pushing part 18, and a positioning block is set on the bottom plate 16. The positioning groove at the bottom of the pushing part 18 needs to be placed corresponding to the positioning block on the bottom plate 16 (the positioning block on the bottom plate 16 is not shown in the figure)). Then, the sampling block 19 is placed down from the upper end of the pushing part 18, so that the sampling block 19 slides along the notch of the outer wall of the pushing part 18. At this time, the supporting part 17 lifts the sampling block 19 at a certain height so that the sampling block 19 can pass through the notch 1301. After placement, the bottom plate 16 can be placed inside the sampling portion 13, and the limiting pin 20 is inserted from the circular hole at the lower end of the sampling portion 13 and inserted into the corresponding limiting opening 1601 of the bottom plate 16, thus completing the limitation of the bottom plate 16; According to the depth of soil sampling, a threaded barrel 15 of appropriate length is selected, and the electric cylinder 21 is placed in the threaded barrel 15 (a backup power supply is provided at the bottom of the electric cylinder 21). Then, the threaded barrel 15 is rotated and installed at the bottom of the bottom plate 16, and the output end of the electric cylinder 21 passes through the middle hole of the bottom plate 16. A thread is provided at the bottom of the push part 18, and the stud 22 at the output end of the electric cylinder 21 can be threadedly rotated in the hole groove, so that the electric cylinder 21 can be stably connected to the push part 18, ensuring that the electric cylinder 21 can stably push up and pull down the push part 18; The outer wall of the sampling part 13 is provided with three notches 1301, and the sampling blocks 19 are also provided with three. The three sampling blocks 19 can be arranged one by one with the sampling blocks 19. After the placement is completed, the sampling part 13 can be pushed downward by holding the handle 11. At this time, the threaded cylinder 15 first contacts the bottom of the pre-sampling port, and then the electric cylinder 21 can be controlled to push the pushing part 18 to move upward, and the pushing part 18 pushes the sampling block 19 to extend out from the notch 1301, and the soil at the predetermined height position is sampled. After the sampling block 19 is sampled, the electric cylinder 21 can be controlled to pull the pushing part 18 to move downward, and the sampling block 19 can slide along the outer wall of the pushing part 18. The groove moves until the sampling block 19 is completely retracted into the sampling part 13, then the handle 11 can be held to pull the sampling part 13 upward to separate from the sampling port, and after the bottom plate 16 is removed, the pushing part 18 and the sampling block 19 can be taken out, and after the sampling block 19 is removed from the pushing part 18, the sample soil collected by the sampling block 19 can be collected (it should be noted that after the bottom plate 16 is installed on the sampling part 13, the initial bottom of the pushing part 18 is placed on the bottom plate 16, and at this time the height of the pushing part 18 is higher than the height of the slot 1301, so as to ensure that when the pushing part 18 moves downward, the sampling block 19 can be normally and completely retracted into the sampling part 13).

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
