At this time, it is necessary to take soil samples from the field.

[0003] Problems with existing technologies:

[0004] 1. Most of the existing field measurement sampling devices adopt a single-point single-time sampling method when in use. Not only is the sampling efficiency low, but the collected samples lack universality, which leads to certain errors in the subsequent test results, thus causing a certain impact on the amount of water and fertilizer used.

[0005] 2. The existing field measurement sampling device is not convenient for collecting and processing the samples collected inside the device after completion, which affects the sampling efficiency of the device.

[0006] 3. The sampling tubes provided on the existing field measurement sampling devices are generally inconvenient to be disassembled and replaced, and thus they may be damaged after being used for a certain period of time, thus affecting the sampling efficiency of the device.

[0007] 4. The existing field measurement sampling device is prone to instability during the sampling process, which may cause the device to be damaged during the soil sample sampling process.

[0008] 5. The existing field measurement sampling devices are mostly simple in structure, which makes the device have a single function in the process of sampling field samples, affecting the sampling efficiency of the device. Summary of the invention

[0025] 2. The present invention can increase the stability of the sampling tube during the sampling process of soil samples through the guide sleeve, and can achieve the automatic cleaning process of the outer wall of the sampling tube by driving the sampling tube to move upward and reset after the sampling is completed. The pressure plate is driven downward by the electric hydraulic rod, and then the worm is driven to rotate under the action of the L-shaped tooth plate and the meshing gear one. The rotation of the worm can achieve the effect of driving the two rotating rods four to rotate with the cooperation of the worm wheel, the rotating rod two, the transmission wheel one and the transmission wheel two.

[0026] 3. The present invention can drive the two placement plates on the left and right sides to approach each other through the rotation of the two rotation rods four under the cooperation of the arranged hinged plate three, hinged plate four, hinged shaft two, fixed block two and concave sliding seat two, thereby achieving the effect of driving the two collection boxes on the left and right sides to move respectively to the bottom of the corresponding two sampling tubes. In the process of driving the two collection boxes on the left and right sides to move relative to each other, the rotation of the right rotation rod four can achieve the effect of driving the rotation rod three to rotate under the cooperation of the arranged bevel gear one, bevel gear two, rotation rod one and bevel gear five.

[0027] 4. The present invention can achieve the effect of driving the three bidirectional screws to rotate in the process of driving the three collection boxes to move to the bottom of the three sampling barrels respectively through the mutual cooperation between the meshing gear 2 and the meshing gear plate. The rotation of the three bidirectional screws can drive the corresponding two arc-shaped clamping plates to approach each other with the cooperation of the provided connecting frame and the fixed rod 2, thereby achieving the effect of fixing the three collection boxes, ensuring the stability of the collection boxes in the process of sampling soil samples falling from the inside of the sampling barrel.

[0053] When using the device to sample soil samples in the field, first place the device at the sampling position, and make the multiple ground nail rods 5 set on the device all inserted into the soil, so as to ensure the stability of the device during the sampling process, then start the motor 15 to drive the bevel gear three 26 to rotate, and then under the action of the bevel gear four 27, the threaded rod 11 can be driven to rotate, and the rotation of the threaded rod 11 can drive the mounting frame 101 to move downward with the cooperation of the internal threaded sleeve 105 and the vertical rod 12, and then the three sampling barrels 24 installed at the lower end thereof can be driven to pass through the three corresponding guide sleeves 13 until they are inserted into the soil to a suitable depth, so that the field soil sample enters the interior of the three sampling barrels 24;

[0054] Then, the motor 15 is started again to drive the bevel gear three 26 to rotate in the opposite direction, and then the three sampling barrels 24 can be driven to move upward and reset with the cooperation of the bevel gear four 27, the vertical rod 12, the mounting frame 101 and the internal threaded sleeve 105.

After the sampling is completed, the three electric hydraulic rods 142 are started to drive the pressure plate 141 to move downward. In the process of driving the pressure plate 141 to move downward, the worm 147 can be driven to rotate with the cooperation of the L-shaped tooth plate 143 and the meshing gear one 146.

[0056] The rotation of the bevel gear five 49 can drive the rotating rod three 42 to rotate, and then the front placement plate 17 can be moved backward with the cooperation of the hinge plate one 43, the hinge plate two 44, the hinge shaft one 45, the fixed block one 46 and the concave sliding seat one 47, until the collection box 20 arranged thereon moves backward to the bottom of the corresponding sampling tube 24, and after the three collection boxes 20 are respectively moved to the bottom of the three sampling tubes 24, the L-shaped toothed plate 143 and the meshing gear one 146 are no longer meshed, and in the process of driving the three collection boxes 20 to move to the bottom of the three sampling tubes 24 respectively, the corresponding bidirectional screw 85 can be driven to rotate with the cooperation of the meshing toothed plate 18 and the meshing gear two 81, and the rotation of the bidirectional screw 85 with the cooperation of the connecting frame 82 and the arc clamping plate 84 can achieve the fixing effect of the three collection boxes 20, thereby ensuring the stability of the collection box 20 in the process of collecting the soil samples falling from the inside of the sampling tube 24;

[0057] After the above operation is completed, the pressure plate 141 is continued to move downward, thereby pushing the three pushing plates 104 to move downward, and then the soil samples inside the three sampling tubes 24 can be pushed into the three collecting boxes 20 respectively with the cooperation of the set pushing rod 102 and the pushing block 106, so as to achieve the collection process of the taken samples, and then the collecting box 20 can be conveniently removed from the device by resetting the device, so as to facilitate the operator to test the samples, so as to determine the amount of dropper water and fertilizer, and when the device is finished using, the sampling tube 24 can be conveniently removed from the device by rotating it, so as to facilitate the cleaning of the inside of the sampling tube 24 or the replacement of the sampling tube 24.
