[0037] See also Figure 1-10 .

[0038] The present invention provides a technical solution for a soil pollution detection sampling device: a soil pollution detection sampling device, which is used to sample contaminated soil, wherein the contaminated soil has a solid surface and is contaminated in a deep layer by various pollution sources and is in a sludge state, and comprises a combined sampler 1 composed of a base 101, a movable arm 102 and a cylinder 103, and a sampling tube 2 arranged on one side of the combined sampler 1, wherein the movable arm 102 is fixedly arranged above the base 101, and the cylinder 103 is fixedly arranged at one end of the movable arm 102, and the connection and arrangement between the base 101, the movable arm 102 and the cylinder 103 are all prior arts, and will not be described in detail herein, and further comprises: It includes a connecting component 3 composed of a connecting tube 301 and a pressing plate 302 arranged at the center of the connecting tube 301, which is arranged between the cylinder 103 and the sampling tube 2 to connect the cylinder 103 and the sampling tube 2; it includes a protective component 4 composed of a plurality of protective plates 401 and a protective block 402 arranged at the lower end of the protective plate 401, which is arranged on the outer wall of the connecting tube 301 to protect the lower end of the sampling tube 2; a control component 5 arranged between the connecting tube 301 and the protective plate 401 to control the sampling tube 2 to extend further; and a driven component 6 arranged between the connecting tube 301 and the protective plate 401 to control the flipping of the protective block 402.

[0039] By setting up a combined sampler 1, a sampling tube 2, a connecting component 3, a protective component 4, a control component 5 and a driven component 6, the combined sampler 1 is used to drive the sampling tube 2 and the protective component 4 to move downward synchronously. The protective component 4 will protect the sampling tube 2 to prevent it from being damaged by debris in the soil during the downward movement of sampling contaminated soil. After entering the sampling position, the sampling tube 2 is extended from the protective component 4 for sampling through the cooperation of the connecting component 3 and the control component 5. At the same time, the driven component 6 will control the lower end of the protective component 4 to open, forming a sampling space for the sampling tube 2. After the sampling is completed, it will be closed again to continuously protect the sampling tube 2.

[0040] In one embodiment, the output shaft of the cylinder 103 is fixedly arranged at the center of one side of the pressing plate 302. The model of the cylinder 103 is SC80X. This is a prior art and will not be described in detail herein. The other side of the pressing plate 302 is fixed to the sampling tube 2 through a connecting rod. A baffle 201 is fixedly arranged at the other end of the sampling tube 2. The baffle 201 is arranged so that the soil entering the protective plate 401 through the gap can be discharged during the downward movement of the sampling tube 2. The protective plate 401 is fixedly arranged on the outer side wall of the connecting tube 301 in a circular shape. The protective plate 401 and the connecting tube 30 1 is hollow, and the internal rotation of the protective plate 401 is provided with a rotating shaft 1 403 and a rotating shaft 2 404 which are symmetrical up and down, and a transmission belt 405 is provided between the rotating shaft 1 403 and the rotating shaft 2 404. The function of the transmission belt 405 is to transmit the synchronous rotation between the rotating shaft 1 403 and the rotating shaft 2 404. A rotating column 4021 is fixedly provided on one end surface of the protective block 402, and a toothed disc 4022 is fixedly provided at the center of the rotating column 4021, and a rotating gear 406 adapted to the toothed disc 4022 is fixedly provided on the rotating shaft 2 404.

[0041] With this design, when the rotating shaft 1 403 rotates, the rotating shaft 2 404 will be driven by the transmission belt 405 to rotate synchronously. When the rotating shaft 2 404 rotates, the rotating gear 406 fixed thereon will drive the gear plate 4022 meshing with it on the protective block 402 to rotate, and at this time the protective block 402 will start to rotate.

[0042] In one embodiment, the control component 5 includes a plurality of circular positioning blocks 501 arranged outside the corners of the protective plate 401 and a transmission bar 502 fixedly arranged at one end of the positioning block 501. The transmission bar 502 passes through the side wall of the connecting cylinder 301. The outer wall of the connecting cylinder 301 is provided with a movable groove 3011 for moving the transmission bar 502. The inner wall of the connecting cylinder 301 is slidably provided with a moving rack 1 503 fixedly connected to the other end of the transmission bar 502. The inner wall of the connecting cylinder 301 is slidably provided with a moving rack 2 505 mirror-symmetrical to the moving rack 1 503. A movable rack 3011 is arranged between the moving rack 1 503 and the moving rack 2 505. There is a transmission gear 504 meshing with both of them, and the transmission gear 504 is rotatably set on the inner wall of the connecting cylinder 301. A steel cable 506 is fixedly set at one end of the movable rack 505, and the other end of the steel cable 506 passes through the adapter pile 507 fixedly set on the connecting cylinder 301 and is connected with the limit block 509. A telescopic spring 508 is set between one end of the limit block 509 and the adapter pile 507. The side wall of the pressing plate 302 is provided with an adapter hole 3021 matched with the limit block 509. When the cylinder 103 drives the pressing plate 302 to move downward, due to the setting of the limit block 509, the connecting cylinder 301 will also move downward synchronously.

[0043] With this design, after the combined sampler 1 is placed in the designated sampling area, the sampling tube 2 is aligned with the sampling position by rotating the movable arm 102, and the cylinder 103 is started by the control key. The output shaft of the cylinder 103 will drive the pressing plate 302 and the connecting tube 301 to press downward synchronously, thereby driving the sampling tube 2 to move downward, and the connecting tube 301 will drive the protective assembly 4 to move into the soil. The protective block 402 at the lower end of the protective plate 401 is arranged in a pyramid shape. At this time, the lower end of the sampling tube 2 is completely protected by the protective plate 401 and the protective block 402. When the sampling tube 2 continues to move downward until the positioning block 501 touches the ground, it continues to move downward. The positioning block 501 01 will be blocked so that it will no longer move downward with the connecting tube 301, and the transmission bar 502 will drive the movable rack 1 503 to move upward, and the transmission gear 504 will immediately drive the movable rack 2 505 to move downward. When the movable rack 2 505 moves downward, the steel cable 506 at one end thereof will be pulled, and then the limit block 509 at the other end will be pulled toward one end. At this time, the telescopic spring 508 will be compressed, and when the limit block 509 is moved out of the adapter hole 3021 on the pressing plate 302, the pressing plate 302 will not drive the connecting tube 301 and the protective plate 401 to continue to move downward. At this time, the pressing plate 302 continues to drive the sampling tube 2 downward.

[0044] In one embodiment, the driven component 6 includes a compression tube 601 arranged between the connecting tube 301 and the protective plate 401, and a pressing end 602 and a moving end 603 are respectively arranged at both ends of the compression tube 601. The pressing end 602 is slidably arranged on the inner wall at the center of the connecting tube 301, and the moving end 603 is slidably arranged on the inner wall of the protective plate 401. The inner wall of the protective plate 401 is slidably arranged with a moving tooth plate 604 fixedly connected to the moving end 603, and a driven tooth ring 605 meshing with the moving tooth plate 604 is fixedly arranged on the rotating shaft 403.

[0045] With this design, when the pressing plate 302 drives the sampling tube 2 to continue to move downward, the lower end of the pressing plate 302 will contact the pressing end 602 at one end of the compression tube 601, so that the moving end 603 at the other end of the compression tube 601 will be lifted upward. When the moving end 603 is lifted upward, it will drive the moving tooth plate 604 to move upward, thereby driving the driven gear ring 605 to drive the rotating shaft 403 to rotate, and driving the protective block 402 at the lower end of the protective plate 401 to open, so that the downward-moving sampling tube 2 is released to the soil, and then sampling is carried out.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
