The working principle is as follows: the soil sampling device for soil environment damage assessment is characterized in that a fixing frame 3 and a base 1 are fixed through bolts 4 before use, and then the soil sampling device is moved to a soil sampling place; before soil sampling is carried out, the second driving motor 12 penetrates through an opening of a top plate of the fixed frame 3, and the sliding seat 10 is abutted against the top plate of the fixed frame 3; a user steps on the pedal 24 with feet, holds the handle 25 with hands to keep the stability of the soil sampling device for soil environmental damage assessment, then starts the second driving motor 12 to drive the sampling rod 14 and the drill bit 15 at the lower end of the sampling rod 14 to rotate, and then starts the first driving motor 6 to drive the sliding seat 10 to move downwards along the sliding rod 9; the sliding seat 10 moves downwards to drive the sampling rod 14 to move downwards, and the drill bit 15 at the lower end of the sampling rod 14 rotates to facilitate drilling into soil; when the slider 10 moves down to abut against the upper surface of the support base 7 and the upper surface of the first drive motor 6 at the same time, the first drive motor 6 and the second drive motor 12 stop operating at the same time. At the moment, the limit grooves 17 on the sampling rod 14 are all positioned below the ground, and then the third driving motor 13 is started to drive the transmission shaft 16 and the gear 18 in interference fit with the transmission shaft 16 to rotate; because the sampling plate 19 is provided with the rack 20 meshed with the gear 18, one side of the sampling plate 19, which is far away from the gear 18, is attached to the inner wall of the limiting groove 17, when the gear 18 rotates, the sampling plate 19 slides out of the limiting groove 17, so that the sampling port 22 at the front end of the sampling plate 19 extends out of the limiting groove 17; after the sampling port 22 extends out of the limiting groove 17, a stop block 23 at the rear end of the sampling plate 19 is contacted with the gear 18, so that the sampling plate 19 stops sliding; then, the second driving motor 12 is started again to rotate the sampling rod 14, and simultaneously, the soil enters the sampling slot 21 through the sampling port 22. The sampling plate 19 that is located the not co-altitude spacing groove 17 on the thief rod 14 can take the soil in the soil horizon of the different degree of depth, can solve current sampling device single and can only carry out the problem of taking a sample to the soil in the soil horizon of a certain specific degree of depth, and it is efficient to take a sample.
It should be noted that the heights of the upper surface of the supporting seat 7 and the upper surface of the first driving motor 6 are the same; the front end face and the rear end face of each of the 2 sampling plates 19 located in the limiting groove 17 are both arc-shaped and have the same radian with the outer wall of the sampling rod 14. When the soil sampling work is completed, the second driving motor 12 stops working; then the third driving motor 13 rotates reversely to make the sampling plate 19 retract into the limit slot 17 and return to the initial position; the first drive motor 6 is then rotated in the reverse direction to raise the carriage 10 and drive the sampling rod 14 out of the soil. When the sliding base 10 rises to abut against the top plate of the fixed frame 3, the sampling rod 14 is completely separated from the soil, and then the second driving motor 12 is started again to continue to rotate reversely, so that the stop blocks 23 at the rear ends of the sampling plates 19 slide out of the limiting grooves 17 until the racks 20 on the sampling plates 19 are separated from the gears 18 at the corresponding positions and are not kept meshed any more; at this moment, the user can take out the sampling plate 19 from the limiting groove 17 by hand, collect soil samples in the sampling grooves 21 of the sampling plates 19, mark the soil samples at different depths and complete the whole soil sampling work.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the utility model and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the utility model and various alternatives and modifications.
