[0037] Among them, two groups of side drill frames 401 are integrally arranged outside the bottom end of the screw propeller 4. The main bodies of the side drill frames 401 are all elliptical rod structures, and the bottom of the side drill frames 401 are all integrally provided with soil-turning barbs 402 that are inclined and equally spaced; the bottom of the side drill frames 401 is higher than the bottom end of the screw structure of the screw propeller 4.

[0038] Among them, a linkage shaft 701 is rotatably arranged in the middle of the handle-type connecting pipe 7 in cooperation with a bearing, and the linkage shaft 701 is connected to the transmission sleeve 3 by bevel gear transmission; a driving motor 702 is fixedly arranged outside the handle-type connecting pipe 7, and the driving motor 702 is connected to the linkage shaft 701 for transmission.

[0039] Among them, a side grip 102 is fixedly arranged on one side of the collection barrel 1. A control button is also arranged at the installation position of the side grip 102. Aluminum pipes are arranged outside the control button to connect the driving motor 702 and the air extraction pump 9, and connection lines for power supply and control are arranged inside the aluminum pipes.

[0040] Among them, an inclined guide plate 802 is integrally arranged inside the separator 8. One end of the inclined guide plate 802 far from the Y-shaped ventilation frame 801 is inclined downward; a blocking net 803 is fixedly arranged between the inner wall of the separator 8 far from the Y-shaped ventilation frame 801 and the top of the inclined guide plate 802.

[0041] Among them, an external connection ring 804 is fixedly arranged at the bottom of the separator 8. A flange structure is integrally arranged on the outer side of the bottom of the external connection ring 804, and a bottle mouth sliding cover 805 is slidably arranged outside the external connection ring 804; a spring is sleeved outside the external connection ring 804, and the spring is located on the top of the bottle mouth sliding cover 805; a cylindrical bottle mouth structure protruding upward is integrally arranged in the middle of the top of the receiving bottle 6, and the bottle mouth sliding cover 805 can be fitted and buckled outside the bottle mouth structure of the receiving bottle 6.

[0042] As Figures 1-9 shown, during use, the handle-type connecting pipe 7 is used as the main grip, and the side grip 102 is used for auxiliary control; manually place the annular airbag 201 on the ground, and seal the collection barrel 1 from the ground through the self-adaptive effect of the annular airbag 201; at this time, the ventilation bent hole 202 can achieve a gas communication effect;

[0043] During operation, it is driven by either wired power supply or stored power supply as needed. Start the driving motor 702 to drive the linkage shaft 701 to rotate. The linkage shaft 701 drives the transmission sleeve 3 to rotate through bevel gears. The transmission sleeve 3 drives the hexagonal shaft 301 to rotate, and the hexagonal shaft 301 can drive the screw propeller 4 to continuously rotate;

[0044] When the screw propeller 4 rotates, manually press the rotary vane 302 downward. The rotary vane 302 can be used to push the screw propeller 4 downward during rotation. The soil-turning barbs 402 first contact the ground to break up the soil surface, and then the soil is transported upward through the spiral structure of the screw propeller 4.

[0045] At the same time, start the air pump 9 to pump air. The air passes through the ventilation bent holes 202 and enters the collection cylinder 1 from the outside to the inside, then passes through the Y-shaped ventilation frame 801 and enters the separator 8. After being intercepted by the intercepting net 803, it passes through the air pump 9 and is discharged to the outside, forming a circulating flow effect.

[0046] During this period, the crushed soil will also rise along with the air flow and enter the separator 8. After the soil enters the separator 8, it is intercepted by the intercepting net 803 and cannot be discharged to the outside. Instead, it is discharged from the external ring 804 at the bottom of the separator 8 into the receiving bottle 6 for collection.

[0047] Embodiment 2: On the basis of Embodiment 1, the material and thickness of the intercepting net 803 can be customized according to needs. Adjust the proportion according to the size of the collection device to ensure the smooth collection of soil.

[0048] In addition, at the external through holes of the ventilation bent holes 202 and at the connection between the Y-shaped ventilation frame 801 and the collection cylinder 1, a barrier net for intercepting stones is provided. The material and size of this barrier net can also be adjusted as needed, and it can also be adjusted as needed to choose whether to install it.

[0049] Embodiment 3: On the basis of Embodiment 1, after collecting the soil sample at one place, the bottle mouth sliding cover 805 can be lifted upward to separate the bottle mouth sliding cover 805 from the bottle mouth structure of the receiving bottle 6. At this time, unlock the receiving bottle 6, and then rotate the receiving bottle 6 and the L-shaped frame 501 to switch the receiving bottle 6. Move another set of receiving bottles 6 under the bottle mouth sliding cover 805 and release the bottle mouth sliding cover 805. The bottle mouth sliding cover 805 automatically buckles to the outside of the bottle mouth structure of the new receiving bottle 6 with the cooperation of the spring to achieve fixation.

[0050] The specific usage method and function of this embodiment: In the present invention, during collection, use the handle-type connecting pipe 7 as the main grip, place the annular airbag 201 on the ground, and seal the collection cylinder 1 from the ground through the self-adaptive effect of the annular airbag 201; at this time, the ventilation bent holes 202 can achieve the gas connection effect.

[0051] Start the drive motor 702 to drive the linkage shaft 701 to rotate. The linkage shaft 701 drives the transmission rotating sleeve 3 to rotate in cooperation with the bevel gear. The transmission rotating sleeve 3 drives the hexagonal shaft 301 to rotate, and the hexagonal shaft 301 can drive the screw propeller 4 to continuously rotate. When the screw propeller 4 rotates, manually press down the rotating vane 302. The rotating vane 302 can push the screw propeller 4 downward during rotation. The soil-turning barbs 402 first contact the ground to break up the soil surface, and then the soil is conveyed upward through the spiral structure of the screw propeller 4.

[0052] Start the air pump 9 to pump air. The air passes through the ventilation bent hole 202 and enters the collection cylinder 1 from the outside to the inside, then passes through the Y-shaped ventilation bracket 801 and enters the separator 8. After being intercepted by the interception net 803, it is discharged to the outside through the air pump 9, forming a circulating flow effect. During this period, the crushed soil will also rise along with the air flow and enter the separator 8. After the soil enters the separator 8, it is intercepted by the interception net 803 and cannot be discharged to the outside. Instead, it is discharged to the receiving bottle 6 from the external ring 804 at the bottom of the separator 8 for collection.

[0053] After completing the collection and filling of a group of receiving bottles 6, lift the bottle mouth sliding cover 805 upward so that the bottle mouth sliding cover 805 disengages from the bottle mouth structure of the receiving bottle 6, unlocking the receiving bottle 6. Then rotate the receiving bottle 6 and the L-shaped frame 501 to switch the receiving bottle 6. Move another group of receiving bottles 6 under the bottle mouth sliding cover 805 and release the bottle mouth sliding cover 805. The bottle mouth sliding cover 805 automatically latches onto the outside of the bottle mouth structure of the new receiving bottle 6 in cooperation with the spring to achieve fixation.

[0054] The already loaded receiving bottle 6 can be directly taken out after switching, sealed, and then stored and subjected to subsequent inspections.
