[0022] The first motor 81 is fixedly installed on the left side of the top of the inner cavity of the shell 10. The output end of the first motor 81 is connected to a threaded rod 82. A screw sleeve 83 is threadedly sleeved on the surface of the threaded rod 82. A guide rod 84 is slidably installed in the inner cavity of the screw sleeve 83.

[0023] The sampling assembly 9 includes a sampling barrel 91, which is fixedly installed on the right side of the screw sleeve 83. A second motor 92 is fixedly installed on the top of the sampling barrel 91. The output end of the second motor 92 passes through the inner cavity of the sampling barrel 91 and is connected to a rotating rod 93. A spiral blade 94 is fixedly sleeved on the surface of the rotating rod 93. A drill bit 95 is fixedly installed on the bottom of the rotating rod 93. By setting the drill bit 95, the soil can be made soft when sampling the soil, making it easier for the rotating rod 93 to be inserted into the soil, thereby facilitating the sampling of the soil.

[0024] A box door is installed on the right side of the top of the front surface of the shell 10 through a hinge, and a visual window is embedded in the center of the front surface of the shell 10. By setting the box door, the battery 14 can be easily replaced to avoid the influence of insufficient power on the soil sampling of the staff, thereby improving work efficiency. By setting the visual window, it is convenient for the staff to observe the sampling situation during soil sampling, thereby cooperating with the use of the sampling component 9.

[0025] A controller 7 is fixedly installed at the center of the top of the crossbar 1, and conical angles 11 are installed on the front and rear sides of the left and right sides of the rectangular frame 6 through rotation of the rotating shaft. Pedals 12 are installed on the left and right sides of the rectangular frame 6 through rotation of the rotating shaft. By setting the conical angles 11, it is easy to insert the equipment into the soil, enhance the stability of the equipment, avoid the problem of tipping over when sampling the soil, and reduce damage to the equipment.

[0026] Rubber gloves are fixedly installed on the left and right sides of the crossbar 1, and handles are fixedly installed on the front surface of the rectangular frame 6. By providing the handles, it is easy to pick up the equipment and also easy to carry when going out, which provides convenience for the staff and reduces the energy consumption of the staff.

[0027] When in use, the staff moves the equipment to the soil sampling location, faces the sampling location, and then rotates the bolt 13 clockwise to raise the inner tube 2, and vice versa. After adjusting to the appropriate position, the rectangular frame 6, the cone angle 11 and the pedal 12 are rotated outward. The staff puts on rubber gloves with both hands and stands on the pedal 12 with both feet to make the cone angle 11 deeply penetrate into the soil, so that the bottom of the shell 10 fits the soil surface. Then the power is turned on through the controller 7 to make all components work normally, and the first motor 81 is started so that the output end of the first motor 81 drives the threaded rod 82 to rotate. Under the guidance of the guide rod 84, the screw sleeve 83 moves downward, thereby causing the sampling assembly 9 to move downward. At this time, the second motor 92 is started so that the second motor 92 drives the rotating rod 93 and the drill bit 95 to rotate clockwise, thereby causing the spiral blade 94 to rotate clockwise. The drill bit 95 rotates clockwise, and the soil becomes soft and penetrates into the soil after continuous clockwise rotation to sample the soil. After sampling, the second motor 92 is turned off, and then the first motor 81 is operated to drive the sampling assembly 9 to move upward. The staff puts the collection bag at the bottom of the sampling tube 91, operates the second motor 92 to rotate counterclockwise, and then starts the second motor 92 again, so that the second motor 92 drives the rotating rod 93 to rotate counterclockwise, and then the spiral blade 94 rotates counterclockwise, and the collected soil is collected. After collection, the rectangular frame 6, the cone angle 11 and the pedal 12 are rotated inwardly to make the inner sides of the two rectangular frames 6 fit together, so that the shell 10 enters the inner cavity of the rectangular frame 6 and, and then the bolt 13 is rotated counterclockwise to make the inner tube 2 reach the shortest height. The staff picks up the handle on the surface of the rectangular frame 6 and is easy to carry.

[0028] In summary, the portable soil testing sampling device, through the rotating column 5, rectangular frame 6, shell 10, sampling tube 91, second motor 92, rotating rod 93 and spiral blade 94, solves the problem of increasing labor intensity and prolonging the time and work efficiency of soil sampling and testing when sampling soil in places with undulating terrain.
