Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and particularly relates to a sampling device for a soil sampling robot and a using method thereof. Background Art

[0002] Soil sampling is an important activity for collecting soil samples to analyze their physical, chemical, and biological properties, serving multiple fields such as agriculture, environmental monitoring, geological surveys, and engineering surveys. The sampling process needs to follow scientific methods and steps to ensure that the collected samples are representative and can truly reflect the actual situation of the soil.

[0003] The existing sampling devices for soil sampling robots usually penetrate the soil with a drill bit to obtain samples, and then temporarily store the collected soil samples in a container waiting for processing. In actual situations, the hardness and structure of different soil types (such as clay, sand, gravel layer) vary greatly, and different diameters of drill bits need to be used for drilling according to different situations. The existing sampling devices are not convenient for switching different drill bits for sampling. For soils with strong viscosity, they tend to adhere to the inside of the drill bit and are not convenient to take out, affecting the operation efficiency. For this reason, a sampling device for a soil sampling robot and a using method thereof are proposed. Summary of the Invention

The drill bit body is continuously impacted to generate vibration, so that the soil sample in the drill bit body falls into the collection box for collection;

[0019] S4. When it is necessary to replace the drill bit body, pull the pull plate. The pull plate drives the second spring to stretch. At the same time, the pull plate drives one end of the fixed rod to no longer pass through the fixed hole. At this time, the drill bit body can be pulled downward to be replaced.

By adopting the above technical solution, the installation substrate 4 is fixedly connected to the robot, and the first motor 3 drives the fixed shaft to rotate. The fixed shaft then drives the sampling component to be used to align with the position where sampling is required through the connecting column 2 and the installation barrel 1. Through such a setting, it is convenient to select drill bits 32 with different diameters for use, meeting the use requirements in different situations; in actual use, the drill bits 32 installed on different sampling components have different diameters. Only the main structure is shown in the drawings and no specific distinction is made. In actual situations, the drill bits 32 are different; an opening is provided on one side of the first installation box 12 so that the other end of the slider 14 can be movably arranged outside the first installation box 12; a plurality of screw holes are provided on the installation substrate 4 so that the sampling device can be installed and fixed on the robot.

[0040] As Figures 1-7As shown, a support bracket 41 is fixedly connected to the outer side of the slider 14. A second mounting plate is fixedly connected to the outer side of the support bracket 41. A fourth motor 18 is fixedly connected above the second mounting plate. A rotating shaft 42 is fixedly connected to the output end on one side of the fourth motor 18. Second mounting holes are formed on both sides above the support bracket 41. The rotating shaft 42 passes through the two second mounting holes. With such a setting, the fourth motor 18 is equipped with a brake, which can stop the rotation of the transmission end and limit the movement of the transmission end through friction, thereby limiting and fixing the rotating shaft 42 when needed.

[0041] As Figures 1-7 shown, a first transmission plate 19 is fixedly sleeved on the outer circumferential surface of the rotating shaft 42. A second transmission plate 20 is fixedly connected to one side of the first transmission plate 19. A third mounting box 36 is fixedly connected above the second transmission plate 20. With such a setting, when the rotating shaft 42 is moved, the first transmission plate 19 and the first transmission plate 19 can be linked.

[0042] As Figures 1-7 shown, a fifth motor 22 is fixedly connected above the inside of the third mounting box 36. A first pulley 23 is fixedly connected to the output end below the fifth motor 22. A transmission belt 24 is wound around the outside of the first pulley 23. A second pulley 25 is wound around the inside of the transmission belt 24. A discharge groove is formed inside the second pulley 25. A discharge port 21 is formed above the third mounting box 36. The position of the discharge port 21 is aligned with the position of the discharge groove. With such a setting, the fifth motor 22 can drive the second pulley 25 to rotate through the first pulley 23 and the transmission belt 24; the discharge groove is a circle with a diameter slightly larger than that of the discharge port 21, which can make the soil sample passing through the discharge port 21 better discharged from the discharge groove; the second pulley 25 is close to the inner wall of the third mounting box 36 to prevent the soil sample passing through the discharge port 21 from falling into the third mounting box 36.

[0043] As Figures 1-7As shown, a third mounting hole is provided on one side of the second drive plate 20. A connecting pipe 26 is fixedly connected below the second pulley 25. The connecting pipe 26 passes through the third mounting hole. A first connecting plate 27 is fixedly connected below the connecting pipe 26. A second connecting plate 31 abuts against the lower side of the first connecting plate 27. Two fixing plates 30 are fixedly connected at equal intervals above the second connecting plate 31. Fixing holes are provided on the outer sides of the two fixing plates 30. Fixing rods 40 are movably installed in the two fixing holes. Pulling plates 28 are fixedly connected to the outer sides of the two fixing rods 40. Second springs 29 are fixedly connected to the inner sides of the two pulling plates 28. Third mounting plates are fixedly connected to the inner sides of the two second springs 29. The two third mounting plates are respectively movably sleeved on the outer sides of the two fixing rods 40. The two sides of the two third mounting plates are fixedly connected to the first connecting plate 27. A drill bit body 32 is fixedly connected below the second connecting plate 31. A collection chamber 34 is provided inside the drill bit body 32. Two through holes 33 are provided at equal intervals below the drill bit body 32. Through such a setting, by pulling the pulling plate 28, the pulling plate 28 drives the second spring 29 to stretch. At the same time, the pulling plate 28 drives one end of the fixing rod 40 to no longer pass through the fixing hole. At this time, the drill bit body 32 can be pulled downward to be replaced. Through such a setting, it is convenient to replace and repair the damaged drill bit body 32, which is convenient for use; the space in the collection chamber 34 is communicated with the spaces in the connecting pipe 26 and the discharge port 21, enabling the soil sample to pass through; the second drive plate 20 is provided with a limiting mechanism on both sides of the third mounting hole, which can limit the connecting pipe 26 so that the connecting pipe 26 can only rotate in the third mounting hole and cannot move up and down.

[0044] As Figures 1-3 , Figures 8-9 shown, four groups of collection components are fixedly connected at equal intervals inside the installation barrel 1. The four groups of collection components have the same structure and are symmetrically arranged. The collection component includes two support rods 9. The two support rods 9 are symmetrically arranged. The outer sides of the two support rods 9 are fixedly connected to the inner wall of the installation barrel 1. Support slots 10 are movably sleeved above the two support rods 9. A collection box 11 is fixedly connected between the two support slots 10. Through such a setting, the positions of the four collection boxes 11 correspond to the positions of the four sampling components respectively; the shape of the support rod 9 is square, and the movement of the collection box 11 can be limited by the support slot 10.

[0045] As Figures 1-3 , Figures 10-11As shown in the figure, a fourth mounting plate is fixedly connected to one side of the connecting column 2. A second motor 5 is fixedly connected above the fourth mounting plate. One output end of the second motor 5 is fixedly connected to a transmission rod. A third mounting hole is formed in one side of the connecting column 2. The transmission rod passes through the third mounting hole. One end of the transmission rod is fixedly connected to a rotating wheel 6. An activity groove 37 is formed in one side of the connecting column 2. The rotating wheel 6 is movably arranged in the activity groove 37. Two fixing grooves are equidistantly formed on the circumferential outer surface of the rotating wheel 6. A first spring 8 is fixedly connected to the rotating wheel 6 in both fixing grooves. Impact blocks 7 are fixedly connected to the outer sides of the two first springs 8. Through such a setting, when the second motor 5 is started through the control panel 43, the second motor 5 drives the rotating wheel 6 to rotate through the transmission rod. The rotating wheel 6 drives the impact blocks 7 to continuously impact the drill bit body 32. At the same time, the first spring 8 can absorb shock to prevent damage. The drill bit body 32 is continuously impacted to generate vibration, so that the soil sample in the drill bit body 32 falls into the collection box 11 for collection. Through such a setting, it is convenient to take out the soil sample and improve work efficiency; the position of the rotating wheel 6 aligned with the rotating wheel 6 corresponds to the collection box 11 at the same time, and the discharge groove position corresponds to the inlet of the collection box 11 up and down.

[0046] As Figures 1-11 shown, a control panel 43 is fixedly connected above the mounting substrate 4. The control panel 43 is electrically connected to the first motor 3, the second motor 5, the third motor 15, the fourth motor 18 and the fifth motor 22. Through such a setting, the control panel 43 can be electrically connected to the robot, and then the control panel 43 is controlled by the robot to control the equipment on the sampling device.

[0047] The usage method of a sampling device for a soil sampling robot provided by the present invention is as follows:

[0048] S1. When in use, the mounting substrate 4 is fixedly connected to the robot. The fixed shaft is driven to rotate by the first motor 3. The fixed shaft then drives the sampling assembly to be used through the connecting column 2 and the mounting barrel 1 to align with the position to be sampled.

[0049] S2. When sampling, the third motor 15 is started through the control panel 43. The third motor 15 drives the screw rod 13 to rotate through the first gear 16 and the second gear 17. The screw rod 13 drives the slider 14 to move downward. The slider 14 then drives the drill bit body 32 to move downward through the support bracket 41, the first transmission plate 19 and the second transmission plate 20. At the same time, the fifth motor 22 is started through the control panel 43. The fifth motor 22 drives the connecting pipe 26 to rotate through the first pulley 23, the transmission belt 24 and the second pulley 25. The connecting pipe 26 drives the drill bit body 32 to rotate through the fixed rod 40. The drill bit body 32 rotates continuously during the downward movement, and the soil sample is pushed into the collection bin 34 through the through hole 33 for collection.

[0050] S3. When it is necessary to take out the collected soil sample, start the fourth motor 18 through the control panel 43. The fourth motor 18 drives the first transmission plate 19 to rotate through the rotating shaft 42, thereby driving the drill bit body 32 to rotate 180 degrees. Start the first motor 3 through the control panel 43. The first motor 3 drives the sampling assembly to rotate through the fixed shaft, the connecting column 2 and the mounting barrel 1 until the drill bit body 32 of the sampling assembly rotates to align with the rotating wheel 6. Start the second motor 5 through the control panel 43. The second motor 5 drives the rotating wheel 6 to rotate through the transmission rod. The rotating wheel 6 drives the impact block 7 to continuously impact the drill bit body 32. At the same time, the first spring 8 can reduce vibration to prevent equipment damage. The continuous impact on the drill bit body 32 generates vibration, causing the soil sample in the drill bit body 32 to fall into the collection box 11 for collection;

[0051] S4. When it is necessary to replace the drill bit body 32, pull the pull plate 28. The pull plate 28 drives the second spring 29 to stretch. At the same time, one end of the fixed rod 40 driven by the pull plate 28 no longer passes through the fixing hole. At this time, the drill bit body 32 can be pulled downward to be replaced.

[0052] It should be noted that during use, the mounting substrate 4 is fixedly connected to the robot. It is connected to the robot power system through the control panel 43. The first motor 3 drives the fixed shaft to rotate. The fixed shaft then drives the sampling assembly to be used through the connecting column 2 and the mounting barrel 1 to align with the position where sampling is required;

[0053] Start the third motor 15 through the control panel 43. The third motor 15 drives the screw 13 to rotate through the first gear 16 and the second gear 17. The screw 13 drives the slider 14 to move downward. The slider 14 then drives the drill bit body 32 to move downward through the support bracket 41, the first transmission plate 19 and the second transmission plate 20. At the same time, start the fifth motor 22 through the control panel 43. The fifth motor 22 drives the connecting pipe 26 to rotate through the first pulley 23, the transmission belt 24 and the second pulley 25. The connecting pipe 26 drives the drill bit body 32 to rotate through the fixed rod 40. The drill bit body 32 rotates continuously during the downward movement, and the soil sample is squeezed and pushed into the collection bin 34 through the through hole 33 for collection.

[0054] When it is necessary to take out the collected soil sample, the fourth motor 18 is started through the control panel 43. The fourth motor 18 drives the first transmission plate 19 to rotate through the rotating shaft 42, thereby driving the drill bit body 32 to rotate 180 degrees. The first motor 3 is started through the control panel 43. The first motor 3 drives the sampling assembly to rotate through the fixed shaft, the connecting column 2 and the mounting barrel 1 until the drill bit body 32 of the sampling assembly rotates to align with the rotating wheel 6. The second motor 5 is started through the control panel 43. The second motor 5 drives the rotating wheel 6 to rotate through the transmission rod. The rotating wheel 6 drives the impact block 7 to continuously impact the drill bit body 32. At the same time, the first spring 8 can absorb shock to prevent equipment damage. The continuous impact on the drill bit body 32 generates vibration, causing the soil sample in the drill bit body 32 to fall into the collection box 11 for collection.

[0055] When it is necessary to replace the drill bit body 32, pull the pull plate 28. The pull plate 28 drives the second spring 29 to stretch. At the same time, one end of the fixed rod 40 driven by the pull plate 28 no longer passes through the fixing hole. At this time, the drill bit body 32 can be pulled down to be replaced. Reverse operation can be used for installation.

[0056] The present invention provides a sampling device and its use method for a soil sampling robot, which solves the problem that in actual situations, the hardness and structure of different soil types such as clay, sand, and gravel layers vary greatly, and different diameters of drill bits need to be used for drilling according to different situations. The existing sampling devices are not convenient for switching different drill bits for sampling. For soils with strong viscosity, they tend to adhere to the drill bit and are not easy to take out, affecting the operation efficiency. It is relatively practical.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
