At the same time, there is no device for collecting the collected soil, so it is necessary to carry a collection box separately, which is inconvenient to use. In addition, soils of different depths are easily confused after sampling, affecting the accuracy of the sampling results. Summary of the invention

[0003] The present invention aims at the technical problems existing in the prior art and provides a soil sampling method to solve the problem that when the existing soil sampling device is in use, it is inconvenient to take out the collected soil, and there is no device for collecting the collected soil, so it is necessary to carry a collection box separately, which is inconvenient to use. In addition, soils of different depths are easily confused after sampling, which affects the accuracy of the sampling results.

[0004] The technical solution of the present invention to solve the above technical problem is as follows: A soil sampling method comprises the following steps:

[0005] S1: Pre-set, prepare the soil sampling device, and transport the sampling device to the sampling location;

[0006] S2: Sampling, sampling the location to be sampled through the soil sampling device;

[0007] The sampling device comprises a fixed frame, and two symmetrically arranged handles are fixedly connected to the side walls of the fixed frame, a distance sensor is fixedly connected to the bottom of the handle, and a connecting rod is fixedly connected to the bottom of the fixed frame, a mounting tube is fixedly connected to the lower end of the connecting rod, and a drill rod is fixedly connected to the lower end of the mounting tube, a first motor is fixedly connected in the fixed frame, and the output end of the first motor is fixed to the upper end of the connecting rod, a monitoring mechanism for monitoring the vertical state of the drill rod is arranged on the top of the fixed frame, and a plurality of sampling mechanisms for sampling soil are arranged in the mounting tube;

[0008] The sampling mechanism includes a plurality of sampling boxes arranged in an array and inserted into the side wall of the mounting tube, and a slope is provided at the bottom of the sampling box, a sampling port is opened on the side wall of the sampling box, and a rotating plate is rotatably connected to the sampling port through a first rotating mechanism, a telescopic tube is fixedly connected to the bottom of the sampling box, and a fixed box is fixedly inserted into the side wall of the mounting tube, a collecting box is slidably connected in the fixed box, and the lower end of the telescopic tube is fixedly inserted in the top of the fixed box, a digital mark is provided on the side wall of the collecting box, and the digital mark is 1, 2, 3, 4, etc., and the sampling box is connected to the inner wall of the mounting tube through a reset mechanism, the movement of the sampling box is pushed by a first pushing mechanism, and a vibration mechanism for knocking and vibrating the sampling box is provided on the side wall of each sampling box.

[0009] The beneficial effects of the present invention are:

[0010] 1) By setting a sampling mechanism, when it is necessary to sample the soil, hold the handle and ensure that the drill rod is vertically downward through the monitoring mechanism. Then, start the first motor. The rotation of the first motor drives the rotation of the connecting rod, the mounting tube and the drill rod, so that the mounting tube enters the soil. At the same time, the sampling depth can be determined through the detection of the distance sensor. When the sampling depth is reached, the first motor is stopped. Then, start the second motor. The rotation of the second motor drives the disc and the fixed rod to rotate clockwise, and drives the conical rod to rotate through the second rotating mechanism. When the conical rod abuts against the side wall of the slider, the second rack abuts against the side wall of the second connecting block. At this time, the conical rod will not rotate along the second rotating shaft, thereby pushing the slider to move in the direction close to the fixed block. At the same time, the second spring is compressed, and the sampling box moves outward from the inside of the mounting tube. At the same time, the soil and the side of the rotating plate The wall is resisted, pushing the rotating plate to rotate upward along the first rotating shaft and open. At the same time, the rotation of the first rotating shaft drives the rotation of the first gear, and then drives the first rack to move. At the same time, the first spring is compressed. At this time, the soil can enter the sampling box and slide along the inclined surface to the telescopic tube and then enter the collecting box for collection, thereby facilitating the collection of the sampled soil. When the conical rod passes over the side wall of the slider, the sampling box can move and reset into the mounting tube under the action of the second spring. At this time, the rotating plate can rotate downward and reset under the action of the first spring, and seal the sampling port. Then, the sampling depth is changed by the rotation of the first motor, and the second motor is driven to rotate clockwise, and this reciprocating process is convenient for sampling soil at different depths, and the sampled soil is sequentially entered into the collection box with digital identification for collection, avoiding confusion and ensuring the accuracy of subsequent test results.

[0011] 2) By setting up a vibration mechanism, after the sampling is completed, the sampling box moves into the installation tube. At the same time, the third gear rolls on the third rack, thereby pushing the rotating rod and the rotating disk to rotate. When the rubber protrusion abuts against the side wall of the moving plate, the moving plate and the knocking rod are pushed to move in the direction close to the sampling box. At the same time, the fourth spring is compressed. When the rubber protrusion passes over the side wall of the moving plate, the moving plate and the knocking rod can move and reset under the action of the fourth spring. This reciprocating process allows the knocking rod to knock and vibrate the side wall of the sampling box back and forth, thereby facilitating the sampled soil in the sampling box to enter the collecting box through the telescopic tube for collection, avoiding soil residue and ensuring the sampling effect and accuracy.

[0012] 3) By setting up a monitoring mechanism, when sampling, turn on the laser head. Under the action of gravity, the laser head can remain in a vertical downward position. When the drill rod is tilted, the light spot of the laser head will no longer be in the center of the cross mark. At this time, by adjusting the drill rod to ensure that the light spot of the laser head is always in the center of the cross mark, the drill rod, mounting tube and connecting rod can be kept in a vertical state, thereby ensuring the accuracy of sampling.

[0013] Based on the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the first rotating mechanism includes a first rotating shaft rotatably connected to the side wall of the sampling port, and the rotating plate is fixedly sleeved on the side wall of the first rotating shaft, the side wall of the sampling box is provided with a mounting groove, and one end of the first rotating shaft passes through the mounting groove and is fixedly connected to the first gear, and the side wall of the mounting groove is connected to the first rack through a first reset component.

[0015] The beneficial effect of adopting the above further solution is that the normal rotation of the rotating plate is ensured. At the same time, when the rotating plate rotates upward along the first rotating shaft to open, the rotation of the first rotating shaft drives the rotation of the first gear, and then drives the first rack to move.

[0016] Furthermore, the first reset assembly includes two symmetrically arranged first connecting blocks fixedly connected to the side walls of the mounting groove, and the side walls of the first connecting blocks are fixedly connected to two symmetrically arranged first guide rods, the first rack is sleeved on the side walls of the first guide rods, and the side walls of the first guide rods are sleeved with a first spring.

[0017] The beneficial effect of adopting the above further solution is that it plays a guiding and resetting role in the movement of the first rack.

[0021] The beneficial effect of adopting the above further scheme is that when the second motor is started, the rotation of the second motor drives the disc and the fixed rod to rotate clockwise, and drives the conical rod to rotate through the second rotating mechanism. When the conical rod abuts against the side wall of the slider, it pushes the slider to move toward the fixed block. At the same time, the second spring is compressed, and the sampling box moves from the inside of the mounting tube to the outside.

[0022] Furthermore, the second rotating mechanism includes two symmetrically arranged support blocks fixedly connected to the other end of the fixed rod, and the side walls of the support blocks are rotatably connected to the rotating blocks via a second rotating shaft, the rotating blocks are fixed to the end of the conical rod, the side walls of the second rotating shaft are fixedly sleeved with a second gear, and the side walls of the support blocks are connected to the second rack via a second reset assembly.

[0023] The beneficial effect of adopting the above further scheme is that when the fixed rod rotates clockwise with the disc, when the conical rod abuts against the side wall of the slider, since the second rack abuts against the side wall of the second connecting block, the conical rod will not rotate along the second rotating shaft at this time, thereby pushing the slider to move toward the fixed block. After the sampling is completed, the fixed rod is reset by rotating counterclockwise with the disc, and when the conical rod abuts against the side wall of the slider, the rotating block rotates with the second rotating shaft, and at the same time, drives the second gear to rotate, and pushes the second rack to move. At this time, the slider and the sampling box will not be pushed to move outward, ensuring that the next time sampling is performed, the sampled soil can still be collected from the collection box marked with a number.

[0024] Furthermore, the second reset assembly includes two symmetrically arranged second connecting blocks fixedly connected to the top of the side wall of the supporting block, and the side wall of the second connecting block is fixedly connected to two symmetrically arranged second guide rods, the second rack is sleeved on the side wall of the second guide rod, and the side wall of the second guide rod is sleeved with a third spring.

[0025] The beneficial effect of adopting the above further solution is that it guides and resets the movement of the second rack.

[0026] Furthermore, the vibration mechanism includes two symmetrically arranged second T-shaped guide rods fixedly connected to the side walls of the sampling box, and the side walls of the second T-shaped guide rods are sleeved with a movable plate, the side walls of the second T-shaped guide rods are sleeved with a fourth spring, and the side walls of the movable plate are fixedly connected with a knocking rod, and the movement of the movable plate is driven by a second pushing mechanism.

[0027] The beneficial effect of adopting the above-mentioned further scheme is that after the sampling is completed, the sampling box moves into the installation tube. At the same time, the movable plate and the knocking rod are pushed to move back and forth by the second pushing mechanism, so that the knocking rod can knock and vibrate the side wall of the sampling box back and forth, thereby facilitating the sampled soil in the sampling box to enter the collection box through the telescopic tube for collection, avoiding soil residue and ensuring the sampling effect and accuracy.

[0028] Furthermore, the second pushing mechanism includes a third connecting block fixedly connected to the side wall of the sampling box, and the bottom of the third connecting block is rotatably connected to a rotating disk via a rotating rod, the side wall of the rotating disk is fixedly connected to a plurality of rubber protrusions arranged in an array, and the upper end of the rotating rod is fixedly connected to a third gear, the side wall of the fixed block is fixedly connected to an L-shaped plate, and the other end of the L-shaped plate is fixedly connected to a third rack.

[0029] The beneficial effect of adopting the above-mentioned further scheme is that when the sampling box moves into the mounting tube, the third gear rolls on the third rack, thereby pushing the rotating rod and the rotating disk to rotate. When the rubber protrusion abuts against the side wall of the movable plate, the movable plate and the knocking rod are pushed to move toward the direction close to the sampling box. At the same time, the fourth spring is compressed. When the rubber protrusion passes over the side wall of the movable plate, the movable plate and the knocking rod can move and reset under the action of the fourth spring.

[0030] Furthermore, the monitoring mechanism includes a U-shaped plate fixedly connected to the top of the fixed frame, and a ball bearing is arranged at the bottom of the U-shaped plate, a laser head is fixedly connected to the side wall of the ball bearing, and a cross mark is arranged at the top of the fixed frame.

[0031] The beneficial effect of adopting the above further scheme is that when sampling is carried out, the laser head is turned on, and under the action of gravity, the laser head can remain in a vertical downward position. When the drill rod is tilted, the light spot of the laser head will no longer be in the center position of the cross mark. At this time, by adjusting the drill rod to ensure that the light spot of the laser head is always in the center position of the cross mark, the drill rod, mounting tube and connecting rod can be kept in a vertical state, thereby ensuring the accuracy of sampling.

When sampling, the laser head 1003 is turned on. Under the action of gravity, the laser head 1003 can maintain a vertical downward state. When the drill rod 15 is tilted, the light spot of the laser head 1003 will no longer be at the center position of the cross mark 1004. At this time, by adjusting the drill rod 15 to ensure that the light spot of the laser head 1003 is always at the center position of the cross mark 1004, it can be ensured that the drill rod 15, the mounting tube 14 and the connecting rod 13 are in a vertical state, thereby ensuring the accuracy of sampling.

[0060] The specific method of use of the present invention is as follows:

[0061] When in use, first, when it is necessary to sample the soil, hold the handle 11, and ensure that the drill rod 15 is vertically downward through the monitoring mechanism, then start the first motor 17, and the rotation of the first motor 17 drives the connection rod 13, the installation tube 14 and the drill rod 15 to rotate. At the same time, when sampling, turn on the laser head 1003. Under the action of gravity, the laser head 1003 can maintain a vertical downward state. When the drill rod 15 tilts, the light spot of the laser head 1003 will no longer be at the center position of the cross mark 1004. At this time, by adjusting the drill rod 15 to ensure that the light spot of the laser head 1003 is always at the center position of the cross mark 1004, the drill rod 15, the installation tube 14 and the connection rod 13 can be ensured to be in a vertical state, thereby ensuring the accuracy of sampling, so that the installation tube 14 is inserted into the soil. At the same time, the sampling depth can be determined by the detection of the distance sensor 12. When the sampling depth is reached, the first motor 17 is stopped;

[0062] Then, the second motor 302 is started, and the rotation of the second motor 302 drives the disc 303 and the fixed rod 304 to rotate clockwise, and drives the conical rod 305 to rotate through the second rotating mechanism. When the conical rod 305 abuts against the side wall of the slider 203, the second rack 405 abuts against the side wall of the second connecting block 501. At this time, the conical rod 305 will not rotate along the second rotating shaft 402, thereby pushing the slider 203 to move in the direction close to the fixed block 201. At the same time, the second spring 204 is compressed, and the sampling box 160 1 moves outward from the inside of the mounting tube 14, and at the same time, the soil abuts against the side wall of the rotating plate 1604, pushing the rotating plate 1604 to rotate upward and open along the first rotating shaft 602. At the same time, the rotation of the first rotating shaft 602 drives the rotation of the first gear 603, thereby driving the first rack 604 to move. At the same time, the first spring 703 is compressed. At this time, the soil can enter the sampling box 1601, slide along the inclined surface 1602 to the telescopic tube 1605, and then enter the collecting box 1607 for collection, so as to facilitate the collection of the sampled soil;

[0063] When the conical rod 305 passes over the side wall of the slider 203, the sampling box 1601 can be moved and reset into the mounting tube 14 under the action of the second spring 204. At this time, the rotating plate 1604 can be rotated and reset downward under the action of the first spring 703, and the sampling port 1603 is sealed. Then, the sampling depth is changed by the rotation of the first motor 17, and the second motor 302 is driven to rotate clockwise, and this reciprocating operation is convenient for sampling soil at different depths, and the sampled soil is sequentially collected in the collection box 1607 with the digital mark 1608 to avoid confusion and ensure the accuracy of subsequent test results.

[0064] After the sampling is completed, the sampling box 1601 moves into the mounting tube 14. At the same time, the third gear 905 rolls on the third rack 907, thereby pushing the rotating rod 902 and the rotating disk 903 to rotate. When the rubber protrusion 904 abuts against the side wall of the moving plate 802, the moving plate 802 and the knocking rod 803 are pushed to move in the direction close to the sampling box 1601. At the same time, the fourth spring 804 is compressed. When the rubber protrusion 904 passes over the side wall of the moving plate 802, the moving plate 802 and the knocking rod 803 can move and reset under the action of the fourth spring 804. This reciprocating process allows the knocking rod 803 to reciprocately knock and vibrate the side wall of the sampling box 1601, thereby facilitating the sampled soil in the sampling box 1601 to enter the collecting box 1607 through the telescopic tube 1605 for collection, thereby avoiding soil residue and ensuring the sampling effect and accuracy.

[0065] Next, the second motor 302 is started to reverse, so that the fixed rod 304 rotates counterclockwise and resets along with the disc 303. When the conical rod 305 abuts against the side wall of the slider 203, the rotating block 403 rotates along with the second rotating shaft 402, and at the same time, drives the second gear 404 to rotate, and pushes the second rack 405 to move. At this time, the slider 203 and the sampling box 1601 will not be pushed to move outward, ensuring that the next sampling can still start from the collection box 1607 with the digital identification 1608 of 1 to collect the sampled soil;

[0066] Finally, the first motor 17 is started to reverse, the drill rod 15 is pulled out from the soil, and each collection box 1607 is taken out.

[0067] In summary: The beneficial effects of the present invention are specifically embodied in that it is convenient to sample soil at different depths, and at the same time, it is convenient to collect the sampled soil, and the sampled soil is sequentially collected into a collection box 1607 with a digital identification 1608, thereby avoiding confusion and ensuring the accuracy of subsequent test results.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
