Description

Technical Field

[0001] This utility model relates to the field of soil sampling, and in particular to a high-intensity stratified soil sampling device. Background Technology

[0002] High-strength stratified soil sampling devices are used to accurately collect soil samples from different depths. These devices are typically made of high-strength materials, enabling stable operation under various complex geological conditions and allowing for stratified soil sampling, ensuring accurate analysis of the physical and chemical properties of each soil layer.

[0003] Traditional soil sampling devices are mostly simple single-sampling tube designs, which can usually only collect samples from one depth and cannot achieve stratified sampling of soil at different depths. This design makes the operation cumbersome and time-consuming, especially when multiple depths need to be sampled, resulting in low efficiency.

[0004] To address the above issues, a high-intensity stratified soil sampling device needs to be designed. Utility Model Content

[0005] To overcome the shortcomings of single sampling tube designs, which typically only allow sampling from one depth and cannot achieve stratified sampling of soil at different depths, this invention provides a high-intensity stratified soil sampling device.

[0006] The technical solution of this utility model is: a high-strength stratified soil sampling device, comprising a support frame, a fixing block, a mounting frame, a first motor, a rotating rod, a winding wheel, a pull rope, a support column, a second motor, a protective cover, a drill bit, and a sampling component. The fixing block is connected to the left side of the support frame, and the mounting frame is connected to the right side of the support frame. The first motor is mounted on the upper side of the mounting frame. The left end of the output shaft of the first motor is connected to the rotating rod, which rotates in conjunction with the fixing block. The winding wheel is connected to the rotating rod, and a pull rope is wound on the winding wheel. The other end of the pull rope is connected to the support column. The protective cover is connected to the lower side of the support column. The second motor is installed inside the protective cover. The lower end of the output shaft of the second motor passes through the protective cover and is connected to the drill bit. The sampling component is set on the outer side of the support column.

[0007] Furthermore, the sampling assembly includes a fixed frame, limiting blocks, a rotating frame, a sampling frame, a connecting plate, an elastic cloth, tension rods, a third motor, and rotating blocks. The fixed frame is connected to the outside of the support column. Multiple limiting blocks are evenly spaced on the outside of the fixed frame. Multiple rotating frames are evenly spaced on the outside of the fixed frame. A sampling frame is placed inside each rotating frame. A connecting plate is connected to the side of each rotating frame near the fixed frame. Each connecting plate is engaged with the fixed frame and the support column. An elastic cloth is connected between each rotating frame and the fixed frame. Multiple tension rods are evenly spaced on the lower inside of the support column. Each tension rod is fixedly connected to the corresponding rotating frame. A third motor is installed on the lower inside of the support column. A rotating block is connected to the output shaft of the third motor.

[0008] Furthermore, it also includes a connecting frame, a collar, and a wiping block. The connecting frame is connected to the upper side of the support frame, the collar is connected inside the connecting frame, and the wiping block is provided inside the collar.

[0009] Furthermore, it also includes rubber blocks, with multiple rubber blocks evenly spaced at the bottom of the support frame.

[0010] Furthermore, the wiping block is made of rubber.

[0011] Furthermore, the size of each sampling frame is designed to fit the corresponding rotating frame.

[0012] The beneficial effects of this invention are as follows: The design of the rotating frame and sampling frame enables the device to perform independent soil sampling at different depths. Each sampling frame can accurately collect soil samples from a specific depth, ensuring the independence and accuracy of the samples. This design avoids mixing and contamination between soil samples from different depths, improving the representativeness and reliability of the samples. The tension rod automatically resets after sampling, returning the rotating frame and sampling frame to their initial positions, simplifying the operation process. The design of the third motor and rotating block ensures accurate sampling each time, and allows for rapid reset after sampling. Attached Figure Description

Detailed Implementation

[0021] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example: A high-intensity stratified soil sampling device, such as Figures 1-7As shown, the system includes a support frame 1, rubber blocks 101, a fixing block 2, a mounting frame 3, a first motor 4, a rotating rod 5, a winding wheel 6, a pull rope 7, a support column 8, a second motor 9, a protective cover 91, a drill bit 92, a connecting frame 16, a collar 17, a wiping block 18, and a sampling assembly. Multiple rubber blocks 101 are evenly spaced at the bottom of the support frame 1 to increase friction and prevent slippage. A fixing block 2 is connected to the left side of the support frame 1, and a mounting frame 3 is connected to the right side. The first motor 4 is mounted on the upper side of the mounting frame 3. A rotating rod 5 is connected to the left end of the output shaft of the first motor 4. The rotating rod 5 rotatably engages with the fixing block 2. A winding wheel 6 is connected to the rotating rod 5. The spool 6 is used to wind the pull rope 7, and the pull rope 7 is unwound and retracted by rotating it. The pull rope 7 is wound on the spool 6, and the other end of the pull rope 7 is connected to the support column 8. The lower side of the support column 8 is connected to the protective cover 91, and the second motor 9 is installed inside the protective cover 91. The protective cover 91 is used to protect the second motor 9. The lower end of the output shaft of the second motor 9 passes through the protective cover 91 and is connected to the drill bit 92. The drill bit 92 can drill through hard rocks or hard soil layers. The upper side of the support frame 1 is connected to the connecting frame 16, and the connecting frame 16 is connected to the collar 17. The collar 17 is equipped with a wiping block 18, which is made of rubber and is used to clean the surface of the pull rope 7. A sampling assembly is installed on the outside of the support column 8. The sampling assembly includes a fixed frame 10, limiting blocks 11, rotating frames 12, sampling frames 121, connecting plate 122, elastic cloth 13, tension rod 14, third motor 15, and rotating block 151. The fixed frame 10 is connected to the outside of the support column 8. Multiple limiting blocks 11 are evenly spaced on the outside of the fixed frame 10. Multiple rotating frames 12 are evenly spaced on the outside of the fixed frame 10. Each rotating frame 12 contains a sampling frame 121. The size of each sampling frame 121 is designed to fit the corresponding rotating frame 12. The sampling frame 121 is used to collect soil samples at different depths. Each rotating frame 12 is located on the side closest to the fixed frame 10. Each rotating frame 12 is connected to a connecting plate 122, and each connecting plate 122 is engaged with the fixed frame 10 and the support column 8. Each rotating frame 12 is connected to the fixed frame 10 with an elastic cloth 13. The elastic cloth 13 can extend as the rotating frame 12 unfolds. Multiple tension rods 14 are evenly spaced on the lower inner side of the support column 8. The tension rods 14 can provide a restoring force to help the rotating frame 12 return to its initial position. Each tension rod 14 is fixedly connected to the corresponding rotating frame 12. A third motor 15 is installed on the lower inner side of the support column 8. A rotating block 151 is connected to the output shaft of the third motor 15. The rotating block 151 contacts each connecting plate 122 in sequence by rotating, controlling the opening and closing of the rotating frame 12.

[0023] When this device is needed to sample layered soil, the operator first places the device at the predetermined soil sampling location, ensuring that the drill bit 92 is directly above the pre-drilled hole. Then, the first motor 4 is started. The output shaft of the first motor 4 drives the rotating rod 5 to rotate, which in turn drives the winding wheel 6 to rotate. As the winding wheel 6 rotates, the pull rope 7 wound on it is gradually released and moves downward along the inside of the wiping block 18. The pull rope 7 drives the support column 8 and all the components below it to move downward along the hole opening. As the support column 8 moves, it in turn drives all the components on it to move downward. When the drill bit 92 moves to contact a hard rock or hard soil layer, the second motor 9 is started. The output shaft 9 drives the drill bit 92 to rotate, and the drill bit 92 begins to drill through hard rocks or hard soil layers. The drill bit 92 continues to work until the hard rocks or hard soil layers are completely drilled through. Subsequently, the pull rope 7 continues to drive the support column 8 and all the components below and above it to move downwards. When the support column 8 and all the components below and above it have moved to the required depth, the first motor 4 and the second motor 9 are turned off, and then the first motor 4 is restarted to run in the reverse direction. The output shaft of the first motor 4 drives the rotating rod 5 to rotate in the reverse direction, and the rotating rod 5 drives the winding wheel 6 to rotate in the reverse direction. During the reverse rotation of the winding wheel 6, the winding wheel 6 retracts the pull rope 7. During the retraction of the pull rope 7, the pull rope 7 is cleaned as it passes the wiping block 18, removing the attached material. Simultaneously, the rope 7 pulls the support column 8 and all its components above and below it, moving it upwards. When the support column 8 reaches the required sampling depth, the third motor 15 is activated. The output shaft of the third motor 15 drives the rotating block 151 to rotate. The rotating block 151 rotates and contacts the first connecting plate 122, applying pressure to it. This causes the first connecting plate 122 to rotate the rotating frame 12, the sampling frame 121, and the tension rod 14 outwards. During the rotation of the rotating frame 12, the elastic cloth 13 gradually unfolds until the rotating frame 12 contacts the soil, allowing the soil to enter the sampling frame 121. After the sampling frame 121 has collected the soil sample at the current depth, the support... As column 8 continues to move upwards towards the next sampling depth, the output shaft of the third motor 15 continues to drive the rotating block 151 to rotate. When the rotating block 151 rotates to contact the second connecting plate 122, during this process, under the reset action of the tension rod 14, the rotating plate, sampling frame 121, first connecting plate 122, and elastic cloth 13 rotate in opposite directions until they return to their initial positions. This process is repeated to sample soil at different depths in sequence. When all sampling frames 121 are filled with soil samples at different depths, the support column 8 and all components below and above it move to their initial positions, and the first motor 4 is turned off.
