The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0025] The soil sampling device according to an embodiment of the present application is described below with reference to the accompanying drawings.
[0026] like Figure 1-Figure 4 As shown, the soil sampling device of the embodiment of the present application may include a barrel 10, a bracket 20, a sampling assembly 30, a filtering mechanism 40, a first driving assembly 50, a retractable mechanism 60, a transmission mechanism 70 and a second driving assembly 80.
[0027] The bottom end of the barrel body 10 is provided with a sampling port 11, and the side wall of the barrel body 10 is provided with a sealing door 12. It should be noted that the sealing door 12 described in this embodiment is opened near the top of the barrel body 10, and one side wall of the sealing door 12 can be pivotally connected to the barrel body 10 through a hinge, and the other side wall of the sealing door 12 can be connected to the barrel body 10 through a snap connection.
[0028] The bracket 20 is fixedly arranged on the elevator (not shown in the figure), and the sampling assembly 30 may include a support frame 31 and three sampling mechanisms 32, wherein the support frame 31 is arranged below the barrel 10. It should be particularly noted that the elevator described in this embodiment may be an elevator with a guide rail, and the bracket 20 is fixed on the lifting platform of the elevator.
[0029] The three sampling mechanisms 32 are distributed around the support frame 31 , and one end of the sampling mechanism 32 is pivotally connected to the support frame 31 , and the other end of the sampling mechanism 32 is pivotally connected to the outer wall of the barrel body 10 .
[0030] The filtering mechanism 40 is rotatably disposed in the barrel body 10 , the first driving assembly 50 is disposed on the outer wall of the barrel body 10 , and the first driving assembly 50 is connected to the filtering mechanism 40 .
[0031] The retractable mechanism 60 is disposed on the top wall of the barrel body 10 , and the output end of the retractable mechanism 60 sequentially passes through the barrel body 10 and the filtering mechanism 40 and is connected to the supporting frame 31 .
[0032] It should be noted that the retractable mechanism 60 described in this embodiment may be an electric retractable rod, a pneumatic cylinder or a hydraulic cylinder, and the initial state of the output end of the retractable mechanism 60 is an extended state.
[0033] One end of the transmission mechanism 70 is fixedly connected to the barrel body 10 , and the other end of the transmission mechanism 70 is rotatably connected to the bracket 20 .
[0034] The second driving assembly 80 is disposed on the bracket 20 , and the second driving assembly 80 is connected to the transmission mechanism 70 .
[0035] Specifically, when soil sampling is required, the relevant staff first needs to control the lifting platform of the elevator to drive the device to descend until the sampling mechanism 32 contacts the soil to be sampled.
[0036] Then, the staff controls the output end of the retractable mechanism 60 to retract and pulls the support frame 31 upward, and the upwardly moved support frame 31 drives the three diffused sampling mechanisms 32 to gather together and sample the soil to be sampled.
[0037] When the soil sampling is completed, the staff can control the second driving assembly 80 to drive the transmission mechanism 70 to drive the barrel body 10, the sampling assembly 30, the filtering mechanism 40, the first driving assembly 50 and the retractable mechanism 60 to rotate synchronously until they stop after rotating 180 degrees. At this time, the soil in the three sampling mechanisms 32 enters the barrel body 10 through the sampling port 11 and falls on the filtering mechanism 40.
[0038] Then, the staff controls the first driving assembly 50 to drive the filter mechanism 40 to rotate, so that the soil to be sampled on the filter mechanism 40 is screened, and the soil with impurities removed is screened into the barrel 10. By integrating soil sampling and soil screening, the soil sample processing time can be effectively shortened, the overall work efficiency can be improved, the labor intensity of the operator can be reduced, and the equipment purchase cost and site requirements can be reduced.
[0039] When the staff needs to take out the soil from which impurities have been removed from the barrel 10 , the staff can take it out by opening the sealing door 12 .
[0040] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 1 and Figure 2 As shown, the sampling mechanism 32 may include a sampling claw 321 and a connecting rod 322, wherein one end of the sampling claw 321 is pivotally connected to the support frame 31, and the outer wall of the other end of the sampling claw 321 is pivotally connected to one end of the connecting rod 322, wherein the three sampling claws 321 form a conical cylinder, and the other end of the connecting rod 322 is pivotally connected to the outer wall of the barrel body 10.
[0041] Further, in one embodiment of the present application, Figure 2 and Figure 4 As shown, the filter mechanism 40 may include a filter mesh plate 41 and an outer gear ring 42 , wherein the filter mesh plate 41 is horizontally arranged in the barrel body 10 and sleeved on the output end of the retractable mechanism 60 .
[0042] An annular slideway 13 is provided on the inner wall of the barrel body 10 , and an opening 14 communicating with the annular slideway 13 is provided on the barrel body 10 . An outer gear ring 42 is rotatably disposed in the annular slideway 13 , and the outer gear ring 42 is sleeved and fixed on the filter screen plate 41 .
[0043] Further, in one embodiment of the present application, Figure 1 , Figure 2 and Figure 4 As shown, the first drive assembly 50 may include a first drive mechanism 51 and a gear 52, wherein one end of the first drive mechanism 51 is fixedly connected to the outer wall of the barrel body 10, and the other end of the first drive mechanism 51 is fixedly connected to the gear 52, and the gear 52 passes through the opening 14 and meshes with the outer gear ring 42.
[0044] It should be noted that the first driving mechanism 51 described in this embodiment may be a servo motor.
[0045] Further, in one embodiment of the present application, Figure 1 , Figure 3 and Figure 4 As shown, the transmission mechanism 70 includes a connecting seat 71 and a worm gear 72 , wherein one end of the connecting seat 71 is fixedly connected to the outer wall of the barrel body 10 , and the other end of the connecting seat 71 is fixedly connected to the worm gear 72 , and the worm gear 72 is rotatably connected to the bracket 20 .
[0046] Further, in one embodiment of the present application, Figure 1 As shown, the second drive assembly 80 may include a second drive mechanism 81 and a worm 82 , wherein the second drive mechanism 81 is disposed on the bracket 20 , and an output end of the second drive mechanism 81 is connected to one end of the worm 82 , and the worm 82 is meshed with the worm wheel 72 .
[0047] It should be noted that the second driving mechanism 81 described in this embodiment may be a driving motor.
[0048] Specifically, when sampling of the soil to be sampled is required, the staff can control the output end of the retractable mechanism 60 to retract and pull the support frame 31 upward, and the upwardly moved support frame 31 drives the three sampling claws 321 to gather together and grab the soil to be sampled.
[0049] After grabbing the soil, the staff can control the second driving mechanism 81 to drive the worm 82 to rotate, and the rotating worm 83 drives the worm wheel 72 to rotate, and the rotating worm wheel 72 drives the sampling mechanism 32, the filtering mechanism 40 and the first driving assembly 50 to rotate synchronously through the connecting seat 71. When rotating 180 degrees, the soil in the sampling claw 321 falls on the filter screen 41 in the barrel body 10.
[0050] Then, the staff controls the first driving mechanism 51 to drive the gear 52 to rotate, and the rotating gear 52 drives the filter screen 41 to rotate through the outer gear ring 42, so as to filter out impurities (such as stones, plant roots, etc.) in the soil, and the soil after the impurities are filtered out enters the barrel body 10. This can effectively shorten the soil sample processing time, improve the overall work efficiency, reduce the labor intensity of operators, and reduce the cost of purchasing equipment and site requirements.
[0051] Then, the staff can take out the soil after removing impurities by opening the sealing door 12. After the soil is taken out, the staff can control the second driving mechanism 81 to drive the worm 82 to drive the worm wheel 72 to continue rotating 180 degrees to reset, and the impurities filtered on the filter screen 41 are discharged from the sampling port 11 of the barrel body 10.
[0052] Further, in one embodiment of the present application, Figure 2 As shown, the soil sampling device may further include an interception mechanism 90 , and the interception mechanism 90 may include a tripod 91 and three groups of interception columns 92 .
[0053] The tripod 91 is fixedly disposed in the barrel body 10 and sleeved on the output end of the retractable mechanism 60 .
[0054] Three groups of intercepting columns 92 are respectively vertically arranged on the three supporting arms of the tripod 91. Each group of intercepting columns 92 may include 6, 7, 8, 9, 10, 11 intercepting columns, etc. The specific number of settings can be selected according to actual conditions and is not limited here. The top of the intercepting column 92 is in contact with the bottom wall of the filter mesh plate 41.
[0055] It is understandable that, by providing the intercepting columns 92, when the filter screen 41 rotates, the rotating filter screen 41 drives the sampled soil to rotate synchronously. When the sampled soil passes through the intercepting columns 92, the multiple groups of intercepting columns intercept the impurities in the sampled soil, and at the same time, the multiple groups of intercepting columns 92 can stir the sampled soil on the filter screen 41, thereby accelerating the filtering efficiency of the sampled soil.
[0056] Optionally, in one embodiment of the present application, Figure 5 As shown, the soil sampling device may further include a guide plate 15 and a baffle 16, wherein the guide plate 15 is located above the filter screen 41 and is fixedly disposed in the barrel body 10, and the guide plate 15 is sleeved on the output end of the retractable mechanism 60, wherein the top surface of the guide plate 15 is a downwardly inclined surface, and the guide plate 15 is provided with an inlet (not specifically marked in the figure) near the bottom end of the inclined surface.
[0057] The baffle 16 is sleeved and fixed on the output end of the retractable mechanism 60 , and is movably connected to the barrel body 10 , and the bottom surface of the baffle 16 is in contact with the top surface of the guide plate 15 , wherein the baffle 16 is used to control the opening and closing of the inlet.
[0058] It can be understood that when the output end of the retractable mechanism 60 retracts and pulls the support frame 31 to drive the three sampling claws 321 to gather together, the baffle 16 also moves upward synchronously and opens the entrance.
[0059] When the screened soil enters the barrel body 10 through the entrance, the staff can control the output end of the retractable mechanism 60 to extend and reset, thereby pushing the baffle 16 to reset and seal the entrance, and then the soil with impurities screened out can be sealed and stored in the barrel body 10 to prevent external dust from contaminating the sampled soil, thereby effectively ensuring the accuracy of the sampled soil detection data.
[0060] In summary, the soil sampling device of the embodiment of the present application can effectively shorten the soil sample processing time, improve overall work efficiency, reduce the labor intensity of operators, and at the same time reduce the cost of purchasing equipment and site requirements.
