Detailed implementation mode

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to the attached drawings of the specification Figures 1-7 , a rapid soil sampling device according to an embodiment of the present invention, as Figure 1 shown, includes a first extraction mechanism 1. A second extraction mechanism 2 is provided at the top of the first extraction mechanism 1. A first adjustment mechanism 3 is rotatably installed on the outer wall of the second extraction mechanism 2; Referring to Figures 3-4 shown, the first extraction mechanism 1 includes a cover plate 101. A U-shaped filter plate 102 is fixedly installed on the inner wall of the cover plate 101. An annular pressure plate 103 is installed between the cover plate 101 and the U-shaped filter plate 102 in a vertically sliding state. A plurality of supporting pressure rods 104 penetrating through the top of the cover plate 101 are fixedly installed on the top of the annular pressure plate 103. Combining Figure 7As shown, a second partition plate 106 is fixedly installed at the bottom of the cover plate 101, and a first partition plate 105 is fixedly installed at the bottom of the U-shaped filter plate 102. The purpose of this setting is that when the cover plate 101 and the U-shaped filter plate 102 are inserted into the soil sample, through the settings of the first partition plate 105 and the second partition plate 106, the soil sample inside the cover plate 101 and the U-shaped filter plate 102 can be isolated from the external sample, and the liquid in the sample can be separated synchronously, so that when the sample is taken out, the solid sample and the liquid sample in the same area can be separated point by point and quantitatively, so as to avoid the problem that only a single liquid sample or solid sample can be taken out during traditional sampling, or the solid-liquid content in the taken-out sample is unbalanced, thus affecting the actual detection results; Referring to Figure 3 and Figure 5 As shown, the second extraction mechanism 2 includes a storage cylinder 21 arranged at the top of the cover plate 101. A suction pipe 22 is fixedly installed inside the storage cylinder 21. The suction pipe 22 extends into the inner cavity of the U-shaped filter plate 102, and a connecting frame 26 fixedly connected to the U-shaped filter plate 102 is fixedly installed on the outer wall of the suction pipe 22. The purpose of this setting is to keep the storage cylinder 21 in a fixed state with the cover plate 101 and the U-shaped filter plate 102. A sealing sleeve 23 is fixedly installed at the top of the storage cylinder 21. A piston rod 24 is installed in the sealing sleeve 23 in a vertically movable state. A piston plate 25 is fixedly installed at the bottom of the piston rod 24. During actual use, when the piston rod 24 is pushed and pulled up and down, the piston plate 25 can be synchronously squeezed or pulled in the inner cavity of the storage cylinder 21, so that the suction pipe 22 can extract the liquid oozing from the soil inside the U-shaped filter plate 102 into the inner cavity of the storage cylinder 21; At the same time, referring to Figure 5As shown in the figure, the first adjusting mechanism 3 includes an external thread sleeve 31 rotatably installed on the outer wall of the storage cylinder 21. An internal thread sleeve 33 is engaged with the outer wall of the external thread sleeve 31. A plurality of support plates 34 fixedly connected to the supporting type pressing rods 104 are fixedly installed on the outer wall of the internal thread sleeve 33. The purpose of such a setting is that when the whole external thread sleeve 31 is rotated, the internal thread sleeve 33 can move up and down on its outer wall, and then synchronously pull a plurality of supporting type pressing rods 104 to move up and down, and then make the annular pressing plate 103 extrude the isolated soil sample inside the cover plate 101 and the U-shaped filter plate 102, so as to fully extrude the liquid in the soil, and the liquid seeps into the inside of the U-shaped filter plate 102 through the U-shaped filter plate 102 and the annular pressing plate 103. Furthermore, in the process of pulling and pushing the piston plate 25 and the piston rod 24, the liquid in the soil can be fully extracted, and during the process that the annular pressing plate 103 continuously extrudes the soil inside the cover plate 101 and the U-shaped filter plate 102, the soil is compacted, which is more convenient for overall taking, and avoids manual solid-liquid separation of the soil again during the subsequent detection process, thus improving work efficiency and being more convenient for actual use; A cover mechanism 4 is provided at the bottom of the first extraction mechanism 1, and a second adjusting mechanism 5 is provided at the top of the first extraction mechanism 1.

[0023] Further, referring to Figure 5 As shown in the figure, a first limit support plate 32 is rotatably installed at the bottom of the external thread sleeve 31. A plurality of supporting type pressing rods 104 are installed inside the first limit support plate 32 in a state of sliding up and down. A telescopic spring 35 is fixedly installed between each of the plurality of support plates 34 and the first limit support plate 32. The purpose of such a setting is that during actual use, after the soil sample is uniformly isolated by the cover plate 101 and the U-shaped filter plate 102, when holding the storage cylinder 21 and deflecting by 36 to rotate the external thread sleeve 31, the internal thread sleeve 33 can drive a plurality of supporting type pressing rods 104 to move up and down on its outer wall. Since the position of the first limit support plate 32 remains unchanged, the distance between the support plate 34 and the first limit support plate 32 changes. Furthermore, with the setting of the telescopic spring 35, the supporting type pressing rods 104 are more stable during the up and down movement. At the same time, a plurality of supporting type pressing rods 104 are arranged in a ring at equal intervals around the top of the annular pressing plate 103, and a plurality of supporting type pressing rods 104 and the support plates 34 are arranged in a one-to-one correspondence. A plurality of telescopic springs 35 are sleeved on the outer walls of the corresponding supporting type pressing rods 104. The purpose of such a setting is that the pressure applied to the annular pressing plate 103 is more uniform, so as to uniformly extrude the liquid from the soil sample inside the cover plate 101 and the U-shaped filter plate 102.

[0024] As a further expansion of this solution, referring to Figure 7As shown, the covering mechanism 4 includes a moving groove 41 formed inside the second partition plate 106. A rotating shaft 42 is rotatably installed inside the moving groove 41. A cover plate 43 is fixedly connected to the bottom of the rotating shaft 42. The number of the moving groove 41 and the cover plate 43 are both set to be multiple. And when in the normal state, the multiple cover plates 43 enclose each other to form a disc shape and block the bottom of the cover plate 101 and the U-shaped filter plate 102.

[0025] Furthermore, a second limiting support plate 44 is fixedly installed on the outer surface of the rotating shaft 42. A first gear disc 45 is fixedly installed on the top of the second limiting support plate 44. A first supporting rotating ring 46 is rotatably installed on the outer wall of the cover plate 101. A first arc gear bar 47 meshing with the first gear disc 45 is fixedly installed on the outer wall of the first supporting rotating ring 46. The purpose of such a setting is that when the first supporting rotating ring 46 deflects on the outer wall of the cover plate 101, combined with the setting of the first arc gear bar 47, the first gear disc 45 can be driven to rotate, and then the second limiting support plate 44 is synchronously driven to deflect the whole rotating shaft 42, so that the cover plate 43 synchronously deflects around the rotating shaft 42 until the multiple cover plates 43 are synchronously moved away from the bottom of the cover plate 101 and the U-shaped filter plate 102, and then the soil sample can be quickly positioned and sampled.

[0026] Furthermore, referring to Figure 4 As shown, the second adjusting mechanism 5 includes a limiting bracket 51 fixedly installed on the top of the cover plate 101. A stepping motor 52 is fixedly installed on the top of the limiting bracket 51. The end of the output shaft of the stepping motor 52 is fixedly connected to a second gear disc 53 rotatably connected to the cover plate 101. A second supporting rotating ring 54 is rotatably installed on the top of the cover plate 101. A second arc gear bar 55 meshing with the second gear disc 53 is fixedly installed on the inner wall of the second supporting rotating ring 54. The purpose of such a setting is that when the stepping motor 52 is started to rotate, the rotating second gear disc 53 can synchronously drive the second arc gear bar 55 to deflect the second supporting rotating ring 54 on the top of the cover plate 101. At the same time, combined with Figure 4 and Figure 7As shown, a connecting strut 56 is fixedly installed at the bottom of the second supporting swivel 54. A connecting balance weight 57 fixedly connected to the first supporting swivel 46 is fixedly installed at the bottom of the connecting strut 56. A third supporting swivel 58 is fixedly installed on the outer wall of the connecting strut 56. The third supporting swivel 58 is rotatably installed on the outer wall of the cover plate 101. The purpose of this setting is that when the second supporting swivel 54 as a whole deflects, through the setting of the connecting strut 56 and the connecting balance weight 57, the first supporting swivel 46 can be synchronously driven to deflect and move on the outer wall of the cover plate 101, so that the first arc-shaped gear bar 47 is displaced to contact the first gear disk 45, and then the first gear disk 45 rotates synchronously, and then the second limiting support plate 44 drives the rotating shaft 42 to deflect synchronously, so as to synchronously drive the cover plate 43 to deflect, so as to quickly take out the solid soil after the soil is compressed by offsetting and covering a plurality of cover plates 43 at the bottoms of the cover plate 101 and the U-shaped filter plate 102.
