[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 This utility model provides a technical solution: a soil pollution collector, including a handheld sampler 1, and an L-shaped mounting frame 2 arranged on the side of the handheld sampler 1 for supporting the positioning mechanism of the handheld sampler 1, arranged on the handheld sampler 1 for limiting the movement trajectory of the handheld sampler 1. The positioning mechanism also includes an adjustment component for facilitating the fixing of the handheld sampler 1 and an active component for adapting to handheld samplers 1 of different specifications, arranged on the L-shaped mounting frame 2 for pressing down and pulling up the handheld sampler 1.

[0022] Specifically, the handheld sampler 1 includes a sampling drill bit 101 arranged on an L-shaped mounting frame 2 for drilling soil, a drill rod 102 arranged at the top of the sampling drill bit 101, a rotating handle 103 arranged on the drill rod 102 for driving the sampling drill bit 101 and the drill rod 102 to rotate, and a movable push rod 104 arranged on the drill rod 102 for discharging soil samples from the sampling drill bit 101.

[0023] Specifically, the pressing and pulling mechanism includes a fixed plate 4 arranged on the side of the L-shaped mounting bracket 2, a threaded sleeve 401 arranged on the fixed plate 4, a lifting screw 402 arranged inside the threaded sleeve 401 and cooperating with the threaded sleeve 401 to rotate and move up and down, and a transmission component arranged on the top of the handheld sampler 1 to connect the pressing and pulling mechanism and the handheld sampler 1. Since the lifting screw 402 moves up and down when it rotates inside the threaded sleeve 401, the rotating handle 103 can be rotated in different directions to enable the lifting screw 402 to drive the handheld sampler 1 to move up and down, realizing the pressing during drilling and the lifting during sampling.

[0024] Specifically, the transmission assembly includes a U-shaped bracket 403 arranged at the bottom of the lifting screw 402, a connecting sleeve 404 arranged at the bottom of the U-shaped bracket 403 in contact with the handheld sampler 1, a fixing pin 405 inserted into the connecting sleeve 404 to reinforce the connection between the U-shaped bracket 403 and the handheld sampler 1, and a rotating handle 103 at the top of the handheld sampler 1 in contact with the connecting sleeve 404 while being reinforced by the fixing pin 405. At this time, rotating the rotating handle 103 will drive the connecting sleeve 404 and the U-shaped bracket 403 to rotate, thereby further driving the lifting screw 402 to rotate within the threaded sleeve 401.

[0025] Example 2 To ensure that the handheld sampler is perpendicular to the ground and to avoid errors in the drilling angle that could affect the drilling depth of the sample, the remaining features are the same as in Example 1.

[0026] Specifically, a positioning mounting bracket 3 is arranged on the side of the L-shaped mounting bracket 2, a movable positioning sleeve 301 is arranged on the positioning mounting bracket 3, a clamping positioning sleeve 302 is arranged on one side of the movable positioning sleeve 301, and cooperates with the movable positioning sleeve 301 to position the handheld sampler 1. A connecting bolt 303 is arranged on the movable positioning sleeve 301 and the clamping positioning sleeve 302 to connect the movable positioning sleeve 301 and the clamping positioning sleeve 302. The clamping positioning sleeve 302 is installed on the movable positioning sleeve 301 using the connecting bolt 303, and the handheld sampler 1 is limited by the vertical hole 304 on the movable positioning sleeve 301 and the clamping positioning sleeve 302.

[0027] Specifically, the adjustment assembly includes a stepped lead screw 306 arranged on the L-shaped mounting bracket 2, a movable groove 307 opened at one end of the movable positioning sleeve 301 near the positioning mounting bracket 3 for accommodating the sliding of the positioning mounting bracket 3 within the movable positioning sleeve 301, a drive handle 309 driving the stepped lead screw 306 to rotate, and the stepped lead screw 306, whose position changes due to rotation, drives the movable positioning sleeve 301 to slide on the positioning mounting bracket 3 through the movable groove 307, a connecting ring 308 connecting one end of the stepped lead screw 306 to the movable positioning sleeve 301, so that the movable positioning sleeve 301 moves to the position of the handheld sampler 1, a connecting ring 308 arranged inside the movable positioning sleeve 301 and connected to one end of the stepped lead screw 306 extending into the movable positioning sleeve 301 for driving the movable positioning sleeve 301 to slide on the positioning mounting bracket 3, and a drive handle 309 arranged at one end of the stepped lead screw 306 for driving the rotation of the stepped lead screw 306.

[0028] Specifically, the movable component includes a vertical hole 304 with the movable positioning sleeve 301 and the clamping positioning sleeve 302 close to each other, and a ball bearing 305 arranged on the inner wall of the vertical hole 304 that contacts the handheld sampler 1, so as to facilitate the movement of the handheld sampler 1 in the vertical hole 304. The ball bearing 305 on the inner wall of the vertical hole 304 can ensure that the handheld sampler 1 can move vertically.

[0029] Example 3 To ensure the stability of the device during use, the L-shaped mounting bracket is fixed to the ground with ground nails to prevent shaking when the device is used by the staff.

[0030] Specifically, the L-shaped mounting frame 2 is also provided with sampling holes 201 at the bottom of the L-shaped mounting frame 2 to expose the collection point of soil samples. Fixed ground nails 202 are arranged at the bottom of the L-shaped mounting frame 2 to strengthen the connection between the L-shaped mounting frame 2 and the ground. The sampling holes 201 at the bottom of the L-shaped mounting frame 2 are used to determine the sampling range, and fixed ground nails 202 are inserted into the ground to reinforce the position of the L-shaped mounting frame 2 and prevent the L-shaped mounting frame 2 from shifting.

[0031] The working principle is as follows: When using this device, the handheld sampler 1 needs to be installed on the L-shaped mounting bracket 2. The drive handle 309 drives the stepped lead screw 306 to rotate. The stepped lead screw 306, which changes position due to rotation, drives the movable positioning sleeve 301 to slide on the positioning mounting bracket 3 through the movable groove 307. The connecting ring 308 connects one end of the stepped lead screw 306 to the movable positioning sleeve 301, so that the movable positioning sleeve 301 moves to the position of the handheld sampler 1. The clamping positioning sleeve 302 is installed on the movable positioning sleeve 301 using the connecting bolt 303. The vertical hole 304 on the movable positioning sleeve 301 and the clamping positioning sleeve 302 limits the handheld sampler 1. At the same time, the ball bearings 305 on the inner wall of the vertical hole 304 can ensure that the handheld sampler 1 can be positioned. In vertical movement, the rotating handle 103 at the top of the handheld sampler 1 needs to contact the connecting sleeve 404 and be reinforced with the fixing pin 405. At this time, rotating the rotating handle 103 will drive the connecting sleeve 404 and the U-shaped bracket 403 to rotate, thereby further driving the lifting screw 402 to rotate in the threaded sleeve 401. Since the lifting screw 402 will rise and fall when rotating in the threaded sleeve 401, rotating the rotating handle 103 in different directions can realize the lifting screw 402 driving the handheld sampler 1 to rise and fall, realizing the pressing during drilling and the lifting during sampling. The L-shaped mounting bracket 2 uses the sampling hole 201 at the bottom to determine the sampling range, and at the same time, the fixing nails 202 are inserted into the ground to reinforce the position of the L-shaped mounting bracket 2 and prevent the L-shaped mounting bracket 2 from shifting.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
