At the same time, when sampling soil at different sampling points, it is not convenient to quickly transfer the device for use, which brings inconvenience to the use and sampling operation of the portable soil sampling device and reduces the sampling efficiency.

[0005] Therefore, in order to solve the above technical problems, this utility model proposes a portable soil sampling device for environmental protection engineering. Utility Model Content

[0006] The main objective of this invention is to provide a portable soil sampling device for environmental engineering, which can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A portable soil sampling device for environmental engineering includes a concave movable base. A sampling mechanism is housed within the concave movable base, comprising a screw, a servo motor, a movable plate, a rotary motor, a rotating base, a sampling drill cylinder, and a push plate. The screw is movably connected to the interior of the concave movable base via rotating rods at both ends. The servo motor is fixedly connected to the top surface of the concave movable base, and its output end is fixedly connected to the rotating rod.

[0009] Preferably, universal wheels are fixedly installed at the four corners of the bottom surface of the concave movable seat, and a push handle is fixedly installed on the left side wall of the concave movable seat. Rotation holes are opened on the top and bottom surfaces of the concave movable seat, and a through hole is also opened on the bottom surface of the concave movable seat located to the right of the rotation hole.

[0010] Preferably, a guide rod is fixedly installed in the recess of the concave movable seat, and rotating rods are fixedly installed at the upper and lower ends of the screw, with the rotating rods movably installed in the rotating holes. The servo motor is fixedly installed on the top surface of the concave movable seat, and the output end of the servo motor is fixedly installed together with the upper rotating rod. A guide hole is opened on the top surface of the movable plate, and the guide rod is movably installed together through the guide hole. A first screw hole is also opened on the top surface of the movable plate to the right of the guide hole, and the movable plate is threadedly connected to the screw through the first screw hole.

[0011] Preferably, the rotary motor is fixedly installed on the right side of the top surface of the movable plate, and a rotating seat is fixedly installed at the bottom of the output end of the rotary motor. The bottom surface of the rotating seat has a slot, and positioning grooves are respectively opened on both sides of the inner wall of the slot.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 - Figure 5 As shown, a portable soil sampling device for environmental engineering includes a concave movable base 1, a sampling mechanism 2 inside the concave movable base 1, and the sampling mechanism 2 includes a screw 8, a servo motor 10, a movable plate 11, a rotary motor 14, a rotating base 15, a sampling drill cylinder 19, and a push plate 25. The screw 8 is movably connected to the inside of the concave movable base 1 through rotating rods 9 at both ends. The servo motor 10 is fixedly connected to the top surface of the concave movable base 1, and the output end of the servo motor 10 is fixedly connected to the rotating rod 9. The movable plate 11 is movably connected to the screw 8 through a first screw hole 13 on the top surface, and the rotary motor 14 is fixedly connected to the top surface of the movable plate 11. The rotating base 15 is fixedly connected to the output end of the rotary motor 14, and the sampling drill cylinder 19 is fixedly connected to the bottom end of the rotating base 15 through a threaded knob 23. The push plate 25 is movably connected to the inside of the sampling drill cylinder 19 through pressure rods 26 on both sides.

[0024] like Figure 2 As shown, universal wheels 3 are fixedly installed at the four corners of the bottom surface of the concave movable seat 1, and a push handle 4 is fixedly installed on the left side wall of the concave movable seat 1. Rotation holes 5 are opened on the top and bottom surfaces of the concave movable seat 1, and a through hole 6 is opened on the bottom surface of the concave movable seat 1 and to the right of the rotation hole 5. By using the push handle 4 in conjunction with the universal wheels 3 on the bottom surface of the concave movable seat 1, the sampling mechanism 2 can be pushed to quickly transfer and sample between different sampling points, and it is convenient for the sampling mechanism 2 to move and carry. The rotation hole 5 is used to cooperate with the rotating rod 9 to realize the rotation operation, and the through hole 6 allows the sampling drill 19 to pass through the concave movable seat 1 and enter the ground to sample the soil.

[0025] like Figure 3As shown, a guide rod 7 is fixedly installed in the recess of the concave movable seat 1. Rotating rods 9 are fixedly installed at the upper and lower ends of the screw 8, and the rotating rods 9 are movably installed in the rotating hole 5. The servo motor 10 is fixedly installed on the top surface of the concave movable seat 1, and the output end of the servo motor 10 is fixedly installed together with the upper rotating rod 9. The top surface of the movable plate 11 is provided with a guide hole 12 and is movably installed together with the guide rod 7 through the guide hole 12. The top surface of the movable plate 11 and the right side of the guide hole 12 are also provided with a first screw hole 13. The movable plate 11 is threadedly connected to the screw 8 through the first screw hole 13. When sampling the soil, the servo motor 10 is turned on to drive the output end to drive the rotating rod 9 to rotate in the rotating hole 5, so that the rotating rod 9 drives the screw 8 to rotate. The movable plate 11 moves downward along the guide rod 7 and the screw 8 through the guide hole 12 and the first screw hole 13 on the top surface, which can provide a downward pushing force to the sampling drill 19, so that the sampling drill 19 enters the bottom surface.

[0026] like Figure 3 and Figure 4 As shown, the rotary motor 14 is fixedly installed on the right side of the top surface of the movable plate 11, and a rotary seat 15 is fixedly installed at the bottom of the output end of the rotary motor 14. The bottom surface of the rotary seat 15 has a slot 16, and the inner walls of the slot 16 have positioning grooves 17 on both sides. The outer wall of the rotary seat 15 also has a through second screw hole 18. Turning on the rotary motor 14 drives the output end to rotate the rotary seat 15. The rotary seat 15 drives the sampling drill 19 so that the sampling drill 19 rotates and moves down into the ground to sample the soil. The slot 16 on the bottom surface of the rotary seat 15 is used to cooperate with the insertion of the connecting seat 20, and the positioning groove 17 is used to cooperate with the positioning block 21 to perform the positioning and insertion function. The second screw hole 18 is used to cooperate with the threaded knob 23 to fix the connecting seat 20.

[0027] like Figure 4 As shown, a connecting seat 20 is fixedly installed on the top surface of the sampling drill cylinder 19, and the connecting seat 20 is inserted into the slot 16. A positioning block 21 corresponding to the positioning groove 17 is fixedly installed on the outer wall of the connecting seat 20, and the positioning block 21 is inserted into the positioning groove 17. A connecting hole 22 is also provided on the outer wall of the connecting seat 20, and the threaded knob 23 is threadedly connected to the second screw hole 18 and passes through the connecting hole 22. After the sampling drill cylinder 19 rotates down and enters the ground to complete the soil sampling, and after it is removed from the ground, the threaded knob 23 can be rotated to move out of the second screw hole 18 and the connecting hole 22. The sampling drill cylinder 19 is then pulled down to move the connecting seat 20 and the positioning block 21 out of the slot 16 and the positioning groove 17 respectively, so that the sampling drill cylinder 19 can be disassembled and collected.

[0028] like Figure 5As shown, a number of soil-drilling saw teeth 27 are fixedly installed on the bottom surface of the sampling drill cylinder 19, and sliding openings 24 are respectively opened on both sides of the outer wall of the sampling drill cylinder 19. The push plate 25 is movably installed inside the sampling drill cylinder 19, and a set of symmetrical pressure rods 26 are fixedly installed on the outer wall of the push plate 25. The pressure rods 26 are movably installed in the sliding openings 24 and pass through the sliding openings 24. The soil-drilling saw teeth 27 installed on the bottom surface of the sampling drill cylinder 19 can make the sampling drill cylinder 19 enter the ground more smoothly and quickly to sample the soil during the rotation and downward movement. After the sampling drill cylinder 19 is disassembled, the pressure rods 26 protruding on both sides of the outer wall are pushed. The pressure rods 26 slide in the sliding openings 24 and push the push plate 25 out of the sampling drill cylinder 19, so that the sampled soil can be completely pushed out of the sampling drill cylinder 19.

[0029] It should be noted that this utility model is a portable soil sampling device for environmental engineering. When sampling soil, the push handle 4 is manually pushed and the universal wheels 3 installed on the bottom of the concave moving seat 1 are used to move the sampling mechanism 2 to the ground sampling point, and the through hole 6 on the concave moving seat 1 is aligned with the sampling point. Then, the connecting seat 20 installed on the top surface of the sampling drill cylinder 19 is inserted into the slot 16 through the positioning blocks 21 installed on both sides and the positioning groove 17 opened on the inner wall of the slot 16. The positioning blocks 21 are inserted into the positioning groove 17. The threaded knob 23 is screwed into the second screw hole 18 opened on the outer wall of the rotating seat 15 and threaded together until the threaded knob 23 is screwed into the second screw hole 18 opened on the outer wall of the rotating seat 15. By passing through the connecting hole 22 on the outer wall of the connecting seat 20 and preventing the threaded knob 23 from turning, the sampling drill cylinder 19 can be installed and fixed at the bottom of the rotating seat 15. Next, the servo motor 10 installed on the top surface of the concave moving seat 1 and the rotary motor 14 on the top surface of the movable plate 11 are turned on. The servo motor 10 drives the rotating rod 9, which is installed at the upper and lower ends of the screw 8, to rotate within the rotating holes 5 on the top and bottom surfaces of the concave moving seat 1. The rotating rod 9 drives the screw 8 to rotate, causing the movable plate 11 to move downwards along the guide rod 7 and the screw 8 through the guide hole 12 and the first screw hole 13 on the top surface, respectively. The sampling drill cylinder 19 moves downwards with the movement of the movable plate 11 and passes through the through hole 6 to the sampling point. When the sampler comes into contact with the soil, the rotary motor 14 drives the output end to rotate the rotating seat 15. The rotating seat 15 then drives the sampling drill 19, which is fixed at the bottom, to rotate. The sampling drill 19 quickly breaks through the soil and drills into the ground through the drilling teeth 27 at the bottom. As the sampling drill 19 moves downward and rotates into the soil, the soil is compacted and enters the interior of the sampling drill 19 to achieve the purpose of soil sampling. After the soil sampling is completed, the rotary motor 14 is turned off, and the output end of the servo motor 10 drives the screw 8 to rotate through the rotating rod 9, causing the movable plate 11 to move upward until the sampling drill 19 is brought out of the ground. Then, the threaded knob 23 is rotated in the reverse direction to remove the threaded knob 23. Then, pull down the sampling drill cylinder 19 to remove it from the bottom of the rotating seat 15. Finally, push the pressure rods 26 protruding above both sides of the outer wall of the sampling drill cylinder 19. The pressure rods 26 will push the push plate 25 to move inside the sampling drill cylinder 19 until the soil sampled inside the sampling drill cylinder 19 is squeezed out of the sampling drill cylinder 19. The columnar soil sample can then be collected and stored. When sampling at different sampling points, simply move the entire device to the sampling location. This facilitates rapid sampling of soil without the need for manual sampling. The sampling operation is simple and convenient. The entire device can quickly sample soil at different sampling points and is easy to move and carry, thereby improving the efficiency of soil sampling.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
