[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a soil sampler for contaminated cultivated land, including a connecting rod 1, the bottom end of the connecting rod 1 is fixedly connected with a pedal 2, the pedal 2 allows the staff to step on it to apply pressure to the sampling tube 10, so that the sampling tube 10 enters deeper soil. The inner wall of the pedal 2 is slidably connected with a slider 3. Refer to Figure 4 , a limiting mechanism is arranged on the inner wall of the slider 3. A positioning block 7 is fixedly connected to the outer wall of the slider 3. The positioning block 7 can be preliminarily inserted into the connecting block 8. After the positioning block 7 is inserted, the reaction force generated by the downward movement of the sampling tube 10 can enable the positioning block 7 to bear part of the reaction force of the limiting block 6. The bottom end of the slider 3 is inserted with a connecting block 8. The connecting block 8 is provided with a notch corresponding to the positioning block 7, which can allow the positioning block 7 to be inserted into it. A limiting groove 9 is opened on the inner side wall of the connecting block 8. The bottom end of the connecting block 8 is fixedly connected with a sampling tube 10. The sampling tube 10 is a prior art, which can insert the sampling tube 10 into the soil of contaminated cultivated land for sampling. There are two groups of sampling tubes 10, and the two groups of sampling tubes 10 are in contact with each other.
[0032] Reference Figure 2 With Figure 5 , the inner wall of the pedal 2 is penetrated and rotatably connected with a threaded rod 11. The left end of the threaded rod 11 is fixedly connected with a turning handle 12. By manually rotating the turning handle 12, the threaded rod 11 rotates forward and backward, so that the sliders 3 approach or separate from each other. The outer wall of the turning handle 12 is elastically connected with a plug 14 through a positioning spring 13. The threaded rod 11 is threadedly connected with the middle part of the slider 3. The outer wall of the turning handle 12 is fixedly connected with one end of the positioning spring 13. When the plug 14 moves to the left, the positioning spring 13 will be stretched. When resetting, the elastic force of the positioning spring 13 is used to drive the plug 14 to reset. The other end of the positioning spring 13 is fixedly connected with the inner side wall of the plug 14. The plug 14 penetrates and slidably connects on the inner wall of the turning handle 12. The plug 14 is inserted into the side wall of the pedal 2. A circle of notches corresponding to the plug 14 is formed on the side wall of the pedal 2, which can allow the plug 14 to be inserted into the notches, so as to reduce the influence of the reaction force generated by the insertion of the sampling tube 10 into the polluted cultivated land soil on the threaded rod 11.
[0033] Reference Figure 4 , the limiting mechanism includes a pressing plate 5. By driving the limiting block 6 to move horizontally on the inner wall of the slider 3 through the pressing plate 5, the outer wall of the pressing plate 5 is elastically connected with the slider 3 through a return spring 4. The outer wall of the pressing plate 5 is fixedly connected with a limiting block 6. The limiting block 6 is beveled. When the bevel surface is squeezed, the limiting block 6 will slide along the inner wall of the slider 3. The outer wall of the pressing plate 5 is fixedly connected with one end of the return spring 4. When the pressing plate 5 moves to the left, the return spring 4 will be compressed. When resetting, the elastic force of the return spring 4 is used to drive the pressing plate 5 to reset. The other end of the return spring 4 is fixedly connected with the left end inner wall of the slider 3. The pressing plate 5 and the limiting block 6 respectively penetrate and slidably connect on the inner wall of the slider 3. Corresponding notches for the pressing plate 5 and the limiting block 6 are respectively formed on the slider 3, which can allow the pressing plate 5 and the limiting block 6 to slide along the notches of the slider 3. The positioning block 7 is inserted into the inner wall of the connecting block 8, and the limiting block 6 is inserted into the inner wall of the limiting groove 9.
[0034] Working principle: When the sampling tube 10 needs to be disassembled first, only need to press the pressing plate 5 to drive the limiting block 6 to move to the left and compress the return spring 4, so that the inner wall of the limiting block 6 and the limiting groove 9 are separated. Then, move the sampling tube 10 with the connecting block 8 out of the left end of the slider 3, so that the inner wall of the positioning block 7 and the connecting block 8 are separated. After moving out, release the pressing plate 5, and use the reverse elastic force of the return spring 4 to drive the pressing plate 5 and the limiting block 6 to reset.
[0035] When the new sampling tube 10 needs to be installed, just insert the connecting block 8 from the left end of the slider 3, so that the right end side wall of the slider 3 presses against the inclined surface of the limiting block 6, causing the limiting block 6 to drive the pressing plate 5 to move leftward and compress the return spring 4. When the inner wall of the limiting block 6 coincides with the inner wall of the limiting groove 9, use the reverse elastic force of the return spring 4 to drive the pressing plate 5 and the limiting block 6 to reset, so that the limiting block 6 is inserted into the inner wall of the limiting groove 9 to unidirectionally limit and install the entire connecting block 8.
[0036] During the use of the sampling tube 10, soil will adhere to the inner walls of the two groups of sampling tubes 10. When it is necessary to better clean the sampling tube 10, just move the insertion block 14 by hand and stretch the positioning spring 13, so that the insertion block 14 is separated from the side wall notch of the pedal 2. Then reverse the rotary handle 12 to drive the threaded rod 11 to rotate, so that the threaded rod 11 drives the two groups of sliders 3, the connecting block 8 and the two groups of sampling tubes 10 to separate from each other. After the two groups of sampling tubes 10 are separated from each other, it is easier to clean the adhered soil and also convenient to take out the soil. When the sampling tubes 10 are spliced and used, the entire rotary handle 12 can be rotated forward to drive the threaded rod 11 to rotate, so that the two groups of sliders 3 drive the sampling tubes 10 to be spliced and used. Finally, release the insertion block 14 and use the reverse elastic force of the positioning spring 13 to drive the insertion block 14 to move rightward and reset, so that the insertion block 14 is inserted into the side wall of the pedal 2.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
