Human production and life are inseparable from land, especially in agricultural production. Soil is the foundation of all agricultural production. Research on the basic physical and chemical properties of different soil types plays a decisive role in formulating appropriate production systems. Soil drills, as a tool for quickly obtaining soil samples from different soil layers, have brought convenience to scientific researchers. However, with the continuous in-depth research and study of soil, more detailed soil sampling is needed to achieve accurate measurement.

[0039] The implementation principle of the soil sample rapid collection device of an auxiliary soil drill in the embodiment of the present application is as follows: the soil drill bit 2 to be taken out of the soil is placed on the top of the bottom plate 1, so that the outer wall of the soil drill bit 2 is in close contact with the inner wall of the push plate 46, and then according to the size of the soil drill bit 2, the two threaded rods 47 are rotated, and the threaded connection relationship between the threaded rods 47 and the threaded grooves 49 causes the threaded rods 47 to drive the clamping plates 48 to slide on the side walls of the push plate 46, so that the two clamping plates 48 clamp the outer wall of the soil drill bit 2;

[0040] Then, according to the soil height that needs to be collected inside the soil drill bit 2, the motor 12 is started, and the motor 12 drives the screw rod 13 to rotate. Through the threaded connection relationship between the screw rod 13 and the threaded seat 11 and the sliding connection relationship between the sliding rod 14 and the sliding groove 15, the threaded seat 11 will slide on the outside of the screw rod 13, and the threaded seat 11 will drive the mounting seat 4 to rise and fall, so as to adjust the height of the auxiliary soil extractor, and according to the marking ruler 8 on one side of the stabilizing shaft 7, it is convenient to intuitively know the lifting height of the auxiliary soil extractor. When the auxiliary soil extractor moves to the soil height that needs to be collected, the motor 12 is stopped, and at this time, the two soil extracting plates 22 are in a closed state;

[0041] Then, the motor 29 is started, and the motor 29 drives the worm 30 to rotate. Through the meshing connection between the worm 30 and the worm wheel 25, the worm wheel 25 is rotated, and the worm wheel 25 drives the installation shaft 1 24 to rotate. The installation shaft 1 24 realizes the rotation of the winding wheel 26, and the winding wheel 26 winds up the connecting rope 23, and makes the connecting rope 23 slide on the outer wall of the roller 28, so that the two earth-taking plates 3 22 slide into the accommodating chamber 21, and the two earth-taking plates 3 22 are opened. Then, the movement of the earth-taking plates 3 22 drives the rotating shaft 31 to slide inside the outer arc plate 18, and makes the movable seat 33 slide inside the sliding opening 2 34. When the earth-taking plates 3 22 approach the connecting seat 20, the spring 1 35 is compressed. When the two earth-taking plates 3 22 are opened to a suitable opening, the motor 29 is stopped.

[0042] Then, the electric push rod 9 is started, and the electric push rod 9 will push the push plate 46 to move, and the push plate 46 will push the soil drill bit 2 to move, so that the soil drill bit 2 can drive the soil to approach the soil plate 1 16 and the soil plate 2 17, so that the soil plate 1 16 and the soil plate 2 17 are inserted into the soil, thereby realizing the layered isolation of the soil to be collected, effectively improving the accuracy of the layered soil collection, and the electric push rod 9 stops working when the soil contacts the ends of the two soil plates 3 22;

[0043] Then, the motor 29 is started to work in the reverse direction, so that the worm 30 drives the worm wheel 25 to reverse, so that the winding wheel 26 can release the rope 23, and under the reverse force of the spring 1 35, the two soil-taking plates 3 22 are pushed to move in the reverse direction, so that the soil-taking plates 3 22 move in the soil. The soil-taking plates 3 22 will drive the rotating shaft 31 to move during the movement, and the rotating shaft 31 will drive the bevel gear 36 to move at the top of the conical tooth plate 38. Through the meshing connection relationship between the bevel gear 36 and the conical tooth plate 38, The bevel gear 36 rotates during the movement, and the bevel gear 36 rotates the rotating shaft 31, which drives the cam 40 to rotate inside the accommodating groove 39. When the outer wall of the long end of the cam 40 is close to one end of the loosening plate 42, the cam 40 pushes the loosening plate 42 to slide inside the arc groove 41, and one end of the loosening plate 42 moves to the outside of the soil-taking plate three 22, so that the loosening plate 42 is inserted into the soil. At the same time, the moving block 44 slides inside the moving groove 43 and compresses the spring two 45. When the outer wall of the long end of the cam 40 is out of contact with the loosening plate 42, the loosening plate 42 is reset under the reverse force of the spring two 45, and then the soil-taking plate three 22 is reciprocatingly inserted into the soil to loosen the soil when the cam 40 rotates repeatedly, which can effectively reduce the compactness of the soil, and then reduce the movement resistance of the soil-taking plate three 22 in the soil, and provide convenience for the two soil-taking plates three 22 to wrap the collected soil. At this time, the collected soil is located on the soil-taking plates In the space formed by the first 16, the second soil taking plate 17, the inner arc plate 19 and the two soil taking plates 3 22, the electric push rod 9 is then operated again to drive the push plate 46 to move in the opposite direction, which will cause the soil drill bit 2 to move in the opposite direction, so that the soil taking plate 1 16 and the second soil taking plate 17 are away from the soil drill bit 2, making it convenient for the soil taking plate 1 16, the second soil taking plate 17, the outer arc plate 18, the inner arc plate 19 and the soil taking plate 3 22 to take out the layered collected soil, effectively improving the convenience and accuracy of layered soil collection in the soil drill bit 2.
