[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a soil sampling device for monitoring the agricultural ecological environment, which has the following beneficial effects:

[0024] 1. By setting up a storage mechanism next to the monitoring sampling vehicle, the device can store materials, so as to perform multiple sampling. By providing a gear and a rack meshing on the sampler, the sampler can be driven to flip during the motion sampling process. Under the action of the second electric push rod, the soil in the sampler can be withdrawn, and in cooperation with the rotatable storage tube, multiple collections can be performed, thereby further improving the sampling efficiency of the soil and facilitating soil sampling.

[0025] 2. The maximum sampling length of the sampler is set to 70 cm. The maximum distance of the sampler squeezing the guide plate when sliding in the guide groove is set to between one tenth and one seventh of the sampler's own length, ensuring that the maximum squeezing depth is 10 cm. In this way, the device has better stability when vibrating. In the prior art, the sampling depth of the soil is generally between 20-60 cm depending on the different sampling conditions. Therefore, this setting not only meets the usage conditions, but also ensures the stability of the device.

[0026] 3. In the setting of the guide plate, a guide groove and a feed hole are opened on the guide plate, and an arc chamfer is set on the feed hole. The sampler can be flipped. When the sampler contacts the guide groove and the arc chamfer, the guide plate and the storage seat can be driven to deviate to one side along the guide block, thereby realizing the separation and docking of the sampler and the feed hole. In addition, when used in conjunction with the spring buffer, it can be automatically reset, with a high degree of automation, thereby improving the efficiency of sampling and storing samples.

[0027] 4. Through the setting of the balancing component, initially, the buffer cylinder is horizontal, the two piston plates in the buffer cylinder slide toward the center, and the tapered rod and the mother-and-child shuttle box are vertically downward, and the sample storage tube at the top is aligned with the feed hole. After the sampling is completed, after all the soil is taken out, the buffer cylinder will rotate due to the loss of gravity balance in an instant, and the liquid in the buffer cylinder will flow and gradually return to the initial state to help the device restore balance. Alternatively, the buffer cylinder can be manually rotated and the mother-and-child shuttle box can be placed at the bottom to help the device quickly restore balance.

[0028] 5. Through the setting of the buffer mechanism, the coordinated movement of the hollow rod, the hollow ball and the piston plate generates vibration under the action of the spring buffer. The liquid in the buffer cylinder will flow to the liquid inlet cavity in the hollow rod, the hollow ball and the piston plate due to the vibration, thereby pushing the sliding plug to contact the inner wall of the limit groove, thereby buffering the rotation of the sample storage tube, thereby ensuring the effect of automatic storage of the sample and preventing it from spilling out.

[0029] 6. By providing a sliding plate and a drill bit at the bottom of the monitoring sampling vehicle, the grip of the monitoring sampling vehicle during sampling can be greatly improved, preventing the monitoring sampling vehicle from tipping over, and further improving the sampling effect.

A feed hole 2101 and a guide groove 2102 are provided on one side of the material guide plate 21. The sampler 6 can contact the guide groove 2102 when rotating.

[0044] A support frame is installed on the top of the material storage seat 16, and a fixed shaft 18 is rotatably connected to the support frame through an embedded bearing. The two ends of the fixed shaft 18 are respectively provided with a supporting mechanism and a buffer mechanism;

[0045] The supporting mechanism includes a rotating disk 17 fixed to one end of a fixed shaft 18, and a plurality of mounting frames 19 distributed in a ring at equal intervals are welded to one side of the rotating disk 17. The inner wall of the mounting frame 19 is clamped with a sample storage tube 20, and the feed hole 2101 is connected and aligned with the topmost sample storage tube 20;

[0046] The buffer mechanism includes a buffer cylinder 23 fixed to the other end of the fixed shaft 18 and a buffer plate 22 fixed to the material storage seat 16. Two hollow buffer ends are sealed and slidably inserted in the buffer cylinder 23. The buffer ends include a piston plate 2301, a hollow rod 2302 and a hollow ball 2303 welded to each other. A limiting groove 2201 is provided on the buffer plate 22. The ball body of the hollow ball 2303 moves in the limiting groove 2201.

[0047] The piston plate 2301 is provided with a liquid inlet 2305, which forms a liquid inlet cavity 2306 with the cylindrical cavity of the hollow rod 2302 and the spherical cavity of the hollow ball 2303. The hollow ball 2303 is also slidably plugged with a sliding plug 2304 that can form friction with the limiting groove 2201.

[0048] The buffer mechanism also includes a balancing component, which includes a mother-and-child shuttle box 2307 welded at the bottom center of the buffer cylinder 23, a spike portion 2308 on the circumference of the center of the bottom inner wall, and a tapered rod 1801 welded on the outer wall of the fixed shaft 18.

[0049] Moreover, the inner wall of the buffer cylinder 23 is thick in the middle and thin at both ends, and the inner wall at the bottom and the inner wall at the top are inclined toward the mother-and-child shuttle box 2307. When the storage mechanism is unloaded, that is, when there is no soil in the sample storage tube 20, the two piston plates 2301 in the buffer cylinder 23 slide toward the center, and the tapered rod 1801 and the mother-and-child shuttle box 2307 are vertically downward, and the sub-box in the mother-and-child shuttle box 2307 passes through the outer wall at the bottom of the buffer cylinder 23. At this time, the center of gravity of the buffer cylinder 23 is downward, and the position is in a horizontal state;

[0050] A bolt spring buffer 24 is passed between one side of the detection sampling vehicle 1 and the guide block 15, and when the sampler 6 is separated from the guide groove 2102, the elastic force generated by the spring buffer 24 is used as power to assist the rotation of the rotating disk 17; at this time, the spring buffer 24 vibrates, and the sample storage tube 20 at the top is heavier, and the balance of the rotating disk 17 is broken, and under the action of gravity, it will move to the lowest end;

[0051] The maximum sampling length of the sampler 6 is 70 cm, and the maximum distance that the sampler 6 squeezes the guide plate 21 when sliding in the guide groove 2102 is between one tenth and one seventh of the length of the sampler 6 itself;

[0052] Among them, a support frame 2 is welded on the top of the monitoring sampling vehicle 1, and a threaded rod 3 is rotatably connected inside the support frame 2. A driving motor is fixed to one side of the support frame 2 by bolts, and the output shaft of the driving motor is connected to the top of the threaded rod 3 by a chain. A slider 4 is slidably connected to the inner wall of the support frame 2, and the slider 4 is threadedly connected to the threaded rod 3. A sampler 6 is rotatably connected to one side of the slider 4 through a bayonet 8. Gears 9 are keyed at both ends of the bayonet 8. Racks 7 are welded on both sides of the top of the support frame 2. The rack 7 can mesh with the gear 9, and the gear 9 can mesh with the rack 7. During the motion sampling process, the sampler 6 can be driven to flip over. A sampling port 5 is provided on the top of the monitoring sampling vehicle 1, and the sampling port 5 is located directly below the sampler 6. A sliding rod 10 is inserted on the top of the sampler 6, and a stripping plate 12 is welded to the bottom of the sliding rod 10, and the stripping plate 12 is slidably connected to the inner wall of the sampler 6. A spring 11 is fixed to one side of the stripping plate 12 by bolts, and one end of the spring 11 is connected to the inner wall of the top of the sampler 6. A card slot 13 is provided on the top of the sliding rod 10, and a first electric push rod 14 is fixed to the top of the support frame 2 by bolts.

[0053] One end of the feed hole 2101 is provided with an arc chamfer 2103 .

[0054] Among them, a monitoring camera 25 for monitoring the environment is provided on the top of the monitoring and sampling vehicle 1, a circuit board 26 and an energy storage battery 31 are provided inside the monitoring and sampling vehicle 1, and a control chip 27 of the model of the control chip 27 is STM32, a wireless communication module 28 of the model of the wireless communication module 28 is AB433A, an obstacle sensing chip 29 and a motion controller 30 are provided on the top of the circuit board 26, the model of the obstacle sensing chip 29 is MS7024, the model of the motion controller 30 is LMC078, and the control chip 27, the wireless communication module 28, the obstacle sensing chip 29 and the motion controller 30 are all electrically connected to the energy storage battery 31.

[0055] Working principle of this embodiment: When sampling soil, the staff only needs to control the monitoring sampling vehicle 1 to move to the specified position. The motion controller 30 can remotely receive the moving command through the wireless communication module 28. At this time, the driving motor is started, driving the threaded rod 3 to rotate, thereby driving the sampler 6 to move downward along the sampling port 5, insert into the soil, and sample the soil. Then the driving motor drives the threaded rod 3 to reverse, driving the sampler 6 to rise slowly. When it rises to a certain height, the gear 9 provided on the top of the sampler 6 engages with the rack 7, thereby driving the sampler 6 to flip 90 degrees counterclockwise. During the flipping process, the sampler 6 first contacts the guide groove 2102 on the guide plate 21, thereby pushing the guide plate 21 and the storage seat 16 to move to one side along the guide block 15. After the sampler 6 is horizontal, it is inserted into the feed hole 2101 and is aligned with the sample storage on the storage mechanism. The storage tubes 20 are on the same plane, and then the second electric push rod 23 drives the storage seat 16 to slide on the guide block 15, so that the sample storage tube 20 is sleeved on one end of the sampler 6, and then the first electric push rod 14 moves to one side and contacts the card slot 13 on the sliding rod 10 at the top of the sampler 6, driving the material stripping plate 12 on the sliding rod 10 to move to one side, thereby stripping the sampled soil and pushing the sampled soil into the sample storage tube 20, and then the storage mechanism is driven to retreat under the action of the second electric push rod 23, and then the threaded rod 3 drives the sampler 6 to reset, and the sampler 6 flips clockwise, and one end of the sampler 6 contacts the arc chamfer 2103, so that the sampler 6 is separated from the feeding hole 2101 by squeezing the guide plate 21 again, and under the action of the spring buffer 24, the guide plate 21 and the storage seat 16 are driven to reset;

[0056] At this time, the sample storage tube 20 at the top contains heavier soil, and the spring buffer 24 will vibrate, breaking the balance of the rotating disk 17. Under the action of gravity, the sample storage tube 20 storing the sample will rotate to the lowest end, thereby driving the empty sample storage tube 20 to rotate to the highest point. The coordinated movement of the hollow rod 2302, the hollow ball 2303 and the piston plate 2301 generates vibration under the action of the spring buffer 24. The liquid in the buffer cylinder 23 will flow to the liquid inlet cavity in the hollow rod 2302, the hollow ball 2303 and the piston plate 2301 due to the vibration, thereby pushing the sliding plug 2304 to contact the inner wall of the limiting groove 2201, thereby buffering the rotation of the sample storage tube 20.

[0057] In this way, sampling is repeated. When the second sample storage tube 20 is filled with soil and starts to fall, gravity causes the sample storage tube 20 at the bottom to rise. Finally, the two sample storage tubes 20 maintain horizontal balance. At this time, in the new state, there is no soil in the top and bottom sample storage tubes 20.

[0058] When sampling for the third time, the top sample storage tube 20 starts to drop again and finally reaches the bottom. The other two sample storage tubes 20 rotate 180 degrees with the rotating disk 17 and reach the opposite position to achieve balance.

[0059] After the fourth sampling, the device storage mechanism is fully loaded and can return.

[0062] Working principle of this embodiment: When in use, when preparing to take samples, first the second electric push rod 36 moves downward, thereby driving the annular slide plate 35 to move downward, thereby driving the sliding plate 32 to move downward along the sliding hole, and at the same time, the second motor 34 drives the drill bit to move downward, thereby improving the stability during sampling and improving the sampling effect.
