[0016] The present invention has the following beneficial effects:

[0017] (1) For the on-site investigation and detection device for soil pollution of the present invention, the hollow sampling drill rod is vertically drilled into the ground by impact or descent. Then, when it is about to reach the designated sampling position, the threaded rod is rotated. The threaded rod drives several internal threaded plates to move downward. The internal threaded plates stably move downward under the limiting action of the limiting strips. The internal threaded plates drive several transmission rods one to move downward. The transmission rod one drives the transmission block to move. The transmission block stably moves away from the threaded rod under the limiting action of the U-shaped limiting rod. The transmission block drives the transmission rod two to move. The transmission rod two drives the T-shaped closing plate to move and open the T-shaped closing plate. After the T-shaped closing plate is opened, soil at each depth is poured into the hollow sampling drill rod through the T-shaped closing groove during the downward movement of the hollow sampling drill rod, enabling sampling of soil at each depth.

[0018] (2) For the on-site investigation and detection device for soil pollution of the present invention, after the soil enters the hollow sampling drill rod and as the hollow sampling drill rod continues to descend, the soil will slowly enter and fall into the collection box along the inclined surface of the rotating plate. When the hollow sampling drill rod descends, the pulling spring will tightly hold the rotating plate to maintain the inclination of the rotating plate, allowing the soil to move along the inclined surface of the rotating plate. The several telescopic springs in the hollow groove will push the telescopic plate under the action of elastic force, preventing the soil from passing through the bottom of the rotating plate and entering the rectangular box, keeping the inside of the rectangular box clean, reducing the cleaning pressure and at the same time reducing the pollution of the collected soil by the gas generated by other soil during detection.

[0019] (3) The present invention provides a soil pollution on-site investigation and detection device. After the soil falls into the collection box, it will fall onto the movable plate. As the soil accumulates more and more, the movable plate will move downward under the action of gravity. The downward movement of the movable plate will drive the movable rod to descend. The movable rod drives the strip cover to descend. The strip cover drives two sealing plates to descend. When the sealing plates descend, they will contact the inclined groove. After contacting the inclined groove, the two sealing plates will move away from each other and contact the inclined groove in a straight line, so that the collection box becomes sealed, preventing other soil or gas from contaminating the soil collected in the collection box and improving the detection accuracy.

[0020] (4) The present invention provides a soil pollution on-site investigation and detection device. After the collection is completed, the threaded rod is rotated, and the threaded rod drives a plurality of internal threaded plates to rise. At this time, a plurality of T-shaped closing plates will slowly close. At this time, the soil entering the hollow sampling drill rod will accumulate to form a filling shape. The T-shaped closing plate will drive the soil to push the hollow circular plate toward the threaded rod. Under the filling effect of the soil, the adapter rod will extend closer to the threaded rod than when there is no soil. At this time, the adapter rod will drive the rubber block to contact the rotating plate under the push of the soil. The rotating plate will rotate. The top of the rotating plate will contact the trapezoidal fixed block during the rotation process. The trapezoidal fixed block will shrink under the elastic force of the fixed spring. After the rotating plate rotates and leaves the trapezoidal fixed block, the trapezoidal fixed block will pop out under the elastic force of the fixed spring, so that the trapezoidal fixed block is stuck to the rotating plate. At this time, the T-shaped closing plate is completely closed. The rotating plate completes the closing of the collection box, so as to avoid the soil in the collection box from contacting other air when the soil collected in the collection box is taken out, thereby further improving the sealing and safety of the soil.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The internal thread plates 202 move downward stably under the limiting action of the limiting strip 204, and the internal thread plates 202 drive a plurality of transmission rods 401 to descend.

[0038] like Figure 2 As shown, a closing mechanism 3 is provided on the hollow sampling drill rod 1, and the closing mechanism 3 includes a plurality of T-shaped closing grooves 301 opened on the hollow sampling drill rod 1, and rotating rods 302 are rotatably installed in the plurality of T-shaped closing grooves 301, and T-shaped closing plates 303 are fixedly sleeved on the plurality of rotating rods 302, and the plurality of T-shaped closing plates 303 are respectively adapted to the plurality of T-shaped closing grooves 301.

[0039] The second transmission rod 403 drives the T-shaped closing plate 303 to move and opens the T-shaped closing plate 303. After the T-shaped closing plate 303 is opened, soil at each depth is poured into the hollow sampling drill rod 1 through the T-shaped closing groove 301 during the downward movement of the hollow sampling drill rod 1, enabling soil sampling at each depth.

[0040] As Figure 2 , Figure 6 and Figure 8 shown, a transmission mechanism 4 is respectively arranged on the bottoms of several internal thread plates 202. The transmission mechanism 4 includes a first transmission rod 401 hinged to the bottom of the internal thread plate 202. The end of the first transmission rod 401 is hinged with a transmission block 402. The top of the transmission block 402 is hinged with a second transmission rod 403. The end of the second transmission rod 403 is hinged with the T-shaped closing plate 303.

[0041] A U-shaped limiting rod 404 is respectively fixedly installed on the inner bottom of the hollow sampling drill rod 1 and the tops of two fixing plates 203. Several U-shaped limiting rods 404 respectively penetrate through the transmission block 402 and are slidably connected with several transmission blocks 402.

[0042] The first transmission rod 401 drives the transmission block 402 to move. The transmission block 402 stably moves away from the threaded rod 201 under the limiting action of the U-shaped limiting rod 404, and the transmission block 402 drives the second transmission rod 403 to move.

[0043] As Figure 6 shown, an adaptation mechanism 5 is respectively arranged on the left and right sides of several transmission blocks 402. The adaptation mechanism 5 includes an adaptation block 501 fixedly installed on the right side of the transmission block 402. An adaptation rod 502 is slidably installed on the adaptation block 501.

[0044] The T-shaped closing plate 303 will drive the soil to push the hollow circular plate 503 closer to the threaded rod 201. Under the filling action of the soil, the adaptation rod 502 will extend more towards the threaded rod 201 than when there is no soil. At this time, the adaptation rod 502 will drive the rubber block 505 to contact the rotating plate 602 under the push of the soil.

[0045] As Figure 3 and Figure 8As shown, a pollution prevention mechanism 6 is respectively arranged on several rectangular boxes 101. The pollution prevention mechanism 6 includes a rotating rod 601 rotatably installed on the rectangular box 101. A rotating plate 602 is fixedly sleeved on the rotating rod 601. A hollow groove 603 is formed in the rotating plate 602. A plurality of telescopic springs 604 are fixedly installed on the top inner wall of the hollow groove 603. The ends of the plurality of telescopic springs 604 are fixedly installed with a telescopic plate 605. The telescopic plate 605 is slidably connected with the hollow groove 603. The end of the telescopic plate 605 extends outside the hollow groove 603.

[0046] The rotating plate 602 will rotate. The top end of the rotating plate 602 will contact the trapezoidal fixing block 803 during the rotation process. The trapezoidal fixing block 803 contracts under the elastic force of the fixing spring 804. After the rotating plate 602 rotates and leaves the trapezoidal fixing block 803.

[0047] As Figure 3 As shown, a pulling mechanism 7 is respectively arranged on the bottom inner walls of several rectangular boxes 101. The pulling mechanism 7 includes a pulling spring 701 fixedly installed on the bottom inner wall of the rectangular box 101. The top end of the pulling spring 701 is fixedly connected with the rotating plate 602.

[0048] When the hollow sampling drill rod 1 descends, the pulling spring 701 will tightly pull the rotating plate 602 to keep the inclination degree of the rotating plate 602, so that the soil moves along the inclined surface of the rotating plate 602.

[0049] As Figure 8 As shown, a fixing mechanism 8 is respectively arranged on the tops of several rectangular boxes 101. The fixing mechanism 8 includes a U-shaped frame 801 fixedly installed on the top of the rectangular box 101. A fixing rod 802 is slidably installed on the U-shaped frame 801. The fixing rod 802 penetrates through the U-shaped frame 801. The bottom end of the fixing rod 802 is fixedly installed with a trapezoidal fixing block 803. The trapezoidal fixing block 803 penetrates through the rectangular box 101. A fixing spring 804 is sleeved on the fixing rod 802. The top end of the fixing spring 804 is fixedly connected with the U-shaped frame 801. The bottom end of the fixing spring 804 is fixedly connected with the trapezoidal fixing block 803.

[0050] The trapezoidal fixing block 803 contracts under the elastic force of the fixing spring 804. After the rotating plate 602 rotates and leaves the trapezoidal fixing block 803, the trapezoidal fixing block 803 will pop out under the elastic force of the fixing spring 804, so that the trapezoidal fixing block 803 catches the rotating plate 602.

[0051] In use, the hollow sampling drill pipe 1 is vertically drilled into the ground by impact or descent. Then, when approaching the designated sampling position, the threaded rod 201 is rotated. The threaded rod 201 drives a number of internal threaded plates 202 to move downward. The internal threaded plates 202 move stably downward under the limiting action of the limiting strips 204. The internal threaded plates 202 drive a number of first transmission rods 401 to descend. The first transmission rods 401 drive the transmission blocks 402 to move. The transmission blocks 402 move stably away from the threaded rod 201 under the limiting action of the U-shaped limiting rods 404. The transmission blocks 402 drive the second transmission rods 403 to move. The second transmission rods 403 drive the T-shaped closing plate 303 to move and slightly open the T-shaped closing plate 303. During the continuous descent of the drill pipe 1, since the T-shaped closing plate 303 is at an inclined angle at this time, the descent of the drill pipe 1 will drive the T-shaped plate 303 to continuously descend to break the soil around the drill pipe 1, causing the acting force around the soil to gradually decrease. By continuously rotating the threaded rod 201, the T-shaped closing plate 303 will continuously open. After the T-shaped closing plate 303 opens, during the downward movement of the hollow sampling drill pipe 1, the soil at each depth is poured into the hollow sampling drill pipe 1 through the T-shaped closing groove 301; after the soil enters the hollow sampling drill pipe 1 and with the continuous descent of the hollow sampling drill pipe 1, the soil will slowly enter and fall into the collection box 102 along the inclined surface of the rotating plate 602. When the hollow sampling drill pipe 1 descends, the pulling spring 701 will tightly pull the rotating plate 602 to maintain the inclination of the rotating plate 602, so that the soil moves along the inclined surface of the rotating plate 602. A number of telescopic springs 604 in the hollow groove 603 will push the telescopic plate 605 under the action of elastic force, preventing the soil from passing through the bottom of the rotating plate 602 and entering the rectangular box 101 to keep the inside of the rectangular box 101 clean;

[0052] After the soil falls into the collection box 102, it will fall onto the movable plate 104. As the soil accumulates more and more, the movable plate 104 will move downward under the action of gravity. The downward movement of the movable plate 104 will drive the movable rod 107 to descend, and the movable rod 107 drives the strip cover 108 to descend. The strip cover 108 drives the two sealing plates 109 to descend. The sealing plates 109 will contact the chute 106 when they descend. After contacting the chute 106, the two sealing plates 109 will move away from each other and contact the chute 106 in a straight line, so that the collection box 102 becomes a sealed state; after the collection is completed, the threaded rod 201 is rotated, and the threaded rod 201 drives several internal threaded plates 202 to rise. At this time, several T-shaped closing plates 303 will slowly close. At this time, the soil entering the hollow sampling drill rod 1 will accumulate to form a filling state, and the T-shaped closing plate 303 will drive the soil to push the hollow circular plate 503 toward the threaded rod 201, under the filling effect of the soil, the adapter rod 502 will extend closer to the threaded rod 201 than when there is no soil. At this time, the adapter rod 502 will drive the rubber block 505 to contact the rotating plate 602 under the push of the soil, and the rotating plate 602 will rotate. The top of the rotating plate 602 will contact the trapezoidal fixed block 803 during the rotation process, and the trapezoidal fixed block 803 will shrink under the elastic force of the fixing spring 804. After the rotating plate 602 rotates and leaves the trapezoidal fixed block 803, the trapezoidal fixed block 803 will pop out under the elastic force of the fixing spring 804, so that the trapezoidal fixed block 803 is stuck to the rotating plate 602. At this time, the T-shaped closing plate 303 is closed, and the rotating plate 602 completes the closing of the collection box 102, so as to avoid the soil in the collection box 102 from contacting other air and causing pollution when the soil collected in the collection box 102 is taken out.
