[0002] With the acceleration of urbanization and industrialization, more and more land is suffering from heavy metal pollution. Heavy metal pollution in soil is hidden, delayed and long-term. Heavy metals enter plants through the root system. Humans consume plants, causing heavy metals to enter the human body and endanger human health. At the same time, heavy metal pollutants will also migrate and be exposed to groundwater and the atmosphere, damaging the ecological environment. When sampling soil, there are areas that need improvement:

[0003] When sampling the soil, the staff inserts the sampling equipment directly into the soil for sampling. Due to the unevenness of the soil, the sampling equipment cannot be inserted vertically into the soil. The sampling equipment may shake left and right after being subjected to the downward pressure of the staff, causing the sampling equipment to drill at an angle. When the sampling equipment is inserted into the deeper soil, the drill bit is easily stuck, resulting in the sampling head being unable to go deeper or be taken out upward, making it impossible for the operator to continue the investigation. The operator needs to use tools such as shovels and pickaxes to dig out all the surrounding soil, which increases the difficulty and time of field investigations. Summary of the Invention

[0043] See also Figure 5The anti-stuck rotating part 71 includes an interface 711, a movable plug rod 712, an auxiliary loosening part 713, a connecting disk 714, a turntable 715, and a clamping seat 716. The interface 711 is provided on the connecting disk 714, and the interface 711 is connected to the movable plug rod 712. The movable plug rod 712 is movably engaged with the clamping seat 716.

[0045] The above-mentioned movable plug rod 712 is used to cooperate with the auxiliary loosening part 713. When the connecting plate 714 cooperates with the soil dividing plate 743 to rotate clockwise or counterclockwise, the auxiliary loosening part 713 and the movable plug rod 712 will assist the soil dividing plate 743 in dredging the surrounding soil as the connecting plate 714 rotates.

[0046] See also Figure 6 The auxiliary loosening member 713 includes a connecting seat T1, an active cavity T2, a universal ball T3, a push rod T4, a swinging member T5, a limiting member T6, and an arc hook T7.

[0047] The above-mentioned push rod T4 is used to cooperate with the swing member T5. The swing member T5 is connected to the arc hook T7. When the arc hook T7 loosens the soil, the arc hook T7 will move under the pressure of the soil. The swing member T5 will move left and right under the action of the universal ball T3 as the arc hook T7 swings, and the push rod T4 supports the swing member T5.

[0048] The working principle of the above technical solution is described below:

[0049] When the present invention is in use, the limit clamp 8 is placed vertically on the soil, and the two shells 66 will contact the soil under the action of the limit clamp 8. The two shells 66 will be adjusted upward or downward according to the height of the soil under the action of the adjustment rod 5 and the movable buckle 1. The adjustment rod 5 will slide and adjust on the engaging slide rail 621. When the limit clamp 8 is in the vertical state, the staff will step on the pads 63 on the two shells 66 with both feet. The gravity of the pads 63 is transmitted to the curved support plate 64, and the weight of the curved support plate 64 will be transferred to the curved support plate 64 under the action of the swing rod. The elastic member 65 is squeezed downward by the bottom. The elastic member 65 has a certain buffering effect, and the force exerted on the curved plate 64 is received and transmitted to the curved plate 64 below. The curved plate 64 will be stretched outwards after being subjected to weight, and the gravity will be transmitted to the shell 66 through the movable cavity 624. The shell 66 will be subjected to weight and the triangular bevel gear 61 will sink downward. The triangular bevel gear 61 will be vertically inserted into the soil under the action of the shell 66. The triangular bevel gear 61 can limit the position of the shell 66, so that the two shells 66 and the limit clamp 8 can be balanced. In the state, the adjusting rod 5 will be adjusted outward or inward in the active cavity 624 with the change of the shell 66. After the shell 66 is adjusted to a certain position, the shell 66 will pass through the opening and closing sleeve 623. The opening and closing sleeve 623 has the elasticity of a spring and will shrink and overlap inward when under pressure. The shell 66 slides into the sliding clamp 622 through the opening and closing sleeve 623. The opening and closing sleeve 623 will rebound upward when not under pressure, and the sliding clamp 622 will form a concave structure with each other, which can limit the adjusting rod 5 to two openings and closings. Between the sleeve plates 623, the sliding and pressing clamp 622 has the characteristics of an air bag and has a certain degree of adhesion on its surface. When the adjusting rod 5 slides into the sliding and pressing clamp 622, the sliding and pressing clamp 622 is pressed and concave inwards and adheres to and wraps around the adjusting rod 5, which can limit the position of the adjusting rod 5. The two adjusting rods 5 and the two shells 66 cooperate with each other to support the limiting cartridge 8 in a vertical state. After the operator applies downward pressure on the equipment, it is not easy to shake left and right, so that the sampling tube 2 can vertically sample the soil under the action of the limiting cartridge 8;

[0050] The operator holds the manipulator 3 and controls the rotary joint 72 by rotating the screw 4. The rotary joint 72 drives the threaded rod 73 to rotate. The threaded rod 73, the loosening piece 74, and the drill bit 75 will rotate at the same time under the drive of the rotary joint 72. The drill bit 75 will extend vertically into the soil. The four soil dividing plates 743 are plugged into each other to form a cross structure. The four soil loosening pieces 74 will rotate in a ring shape and at the same time to evacuate the soil. The soil dividing plate 743 is provided with a plurality of soil dividing teeth 741. The soil dividing teeth 741 can assist the soil dividing plate 743 to break the soil in layers. The connecting plate 714 and the turntable 715 will move with the rotation of the soil dividing plate 743, and the soil will be dredged through the multiple curved hooks T7 on the connecting plate 714. The curved hooks T7 When the swing member T5 is pressed by the soil, it will swing backward under the action of the universal ball T3 due to the influence of the curved hook T7. The position of the universal ball T3 is fixed by the connecting seat T1. The backward movement of the swing member T5 will squeeze the push rod T4 on one side. The push rod T4 will retract inward under the pressure, which can effectively limit the swing member T5 to move inside the limiting member T6, preventing the curved hook T7 from being unable to reset due to excessive force. The soil is loosened by the cooperation between the soil dividing teeth 741 and the curved hook T7, so that the threaded rod 73 can quickly drive the drill bit 75 downward to drill deeply into the soil. When the screw rod 4 is rotated to cooperate with the threaded rod 73 during the drilling process, the sampling tube 2 will be vertically inserted into the soil, so that the deep soil can be sampled.

[0051] After the sampling is completed, the manipulator 3 controls the rotating screw 4 to drive the rotary joint 72 to rotate in the opposite direction. The threaded rod 73, the loosening piece 74, and the drill bit 75 will also rotate counterclockwise under the drive of the rotary joint 72. When the connecting disk 714 rotates counterclockwise, the back of the auxiliary loosening piece 713 will be pressed by the soil, and the swinging piece T5 will swing forward under the action of the universal ball T3 due to the influence of the curved hook T7. The elastic push rod T4 under pressure on one side will generate a rebound force to push the swinging piece T5 to the other side, so that the curved hook T7 will be pressed against the edge of the connecting disk 714 under the pressure of the soil. The movable insertion rod 712 will move on the holder 716 and extend outward from the connecting plate 714 through the interface 711. The end of the movable insertion rod 712 is in a pointed state. When the threaded rod 73 rotates back, the movable insertion rod 712 will penetrate into the soil, causing the soil to loosen to a certain extent, so that the four loosening pieces 74 and the drill bit 75 can drive the sampling tube 2 to move upward and be exported. The drill bit can be quickly removed upward through the cooperation of the anti-stuck rotation piece 71, the threaded rod 73, and the loosening piece 74, so that the drill bit will not be stuck due to excessive penetration into the soil, effectively reducing the sampling difficulty of the operator.

[0052] In summary, the present invention adopts the combination of movable buckle, sampling tube, manipulator, rotating screw, adjusting rod, leveling support, drilling device and limiting cartridge to form a new heavy metal contaminated soil sampling equipment. When sampling the soil, the two adjusting rods are movably adjusted on the movable slide so that the limiting cartridge can be vertically inserted into the soil. The staff members step on the pads on the two shells with their feet respectively. The shells will sink under the weight, and the triangular bevel gears will be inserted into the soil under the action of the shells, so that the two shells can vertically position the limiting cartridge. The rotating screw drives the threaded rod and the drill bit to drill the soil clockwise or counterclockwise under the action of the rotary joint. During the drilling process, the four loosening parts and anti-stuck parts will cooperate with each other to assist the drill bit to loosen the soil as the threaded rod rotates, so that the threaded rod can quickly drill the soil without being easily stuck in the soil, and the sampling tube 2 can quickly sample the soil for testing.
