[0030] Please refer to Figures 1 - 3 , in the embodiments of the present utility model, a soil environment detection and screening extraction device includes a screening machine 1, a vertical rod 2 is fixed at the top of the screening machine 1, a screen 3 is arranged inside the vertical rod 2 above the screening machine 1, and a limit mechanism 4 arranged on the vertical rod 2;

[0031] The limit mechanism 4 includes a limit unit and a transmission unit;

[0032] The limit unit is used to limit the movement of the positioning rod 401;

[0033] The transmission unit is used to transmit a thrust for the movement of the limit unit;

[0034] The limit unit includes a positioning rod 401, a limit block 403, a spring 404, and a limit groove 408;

[0035] The positioning rod 401 is sleeved on the outer wall of the vertical rod 2, and the positioning rod 401 is used to limit the screen 3;

[0036] The limit block 403 is slidably arranged inside the positioning rod 401, and the limit block 403 is used to cooperate with the limit groove 408 to limit the movement of the positioning rod 401;

[0037] Both ends of the outer wall of the spring 404 are respectively clamped on the outer wall of the limit block 403 and the inner wall of the positioning rod 401, and the spring 404 is used to always provide a thrust in one direction for the limit block 403;

[0038] The limit groove 408 is opened on the outer wall of the vertical rod 2, and the limit groove 408 is used to provide a docking space for the docking of the limit block 403;

[0039] The transmission unit includes a pressing rod 402, a movable block 405, a rotating rod 406, and a movable rod 407;

[0040] The pressing rod 402 is axially slidably installed on the inner wall of the positioning rod 401 and extends to the outside of the positioning rod 401. The pressing rod 402 is used to drive the limit block 403 and the spring 404 to move synchronously;

[0041] The movable block 405 is rotatably installed at the end of the pressing rod 402. The movable block 405 is used to transmit a thrust for the rotation of the movable block 405;

[0042] The rotating rod 406 is rotatably installed inside the positioning rod 401. The rotating rod 406 is used to drive another movable block 405 to rotate synchronously;

[0043] The movable rod 407 is axially slidably installed on the inner wall of the positioning rod 401 and its end is rotatably connected to another movable block 405. The movable rod 407 is used to drive another limit block 403 to move synchronously.

[0044] In this embodiment: When using this device, when it is necessary to screen the materials inside the screen 3, the screen 3 filled with materials can be placed above the screening machine 1. Before that, by applying a pressing force to the pressing rod 402, the pressing rod 402 axially moves along the inner wall of the positioning rod 401. The axially moving pressing rod 402 synchronously drives the limit block 403 and the end of the movable block 405 to move. One limit block 403 will move out of the inner side of the limit groove 408, and the movement of the movable block 405 will give a rotational thrust to the rotating rod 406, causing the rotating rod 406 to rotate. The rotating rotating rod 406 pulls another movable block 405 to rotate circumferentially. By pulling the movable rod 407 axially through another movable block 405, another limit block 403 synchronously moves along with the movement of the movable rod 407. Then the two limit blocks 403 will synchronously move out of the inner side of the limit groove 408 on the outer wall of the vertical rod 2. At this time, an upward thrust can be given to the positioning rod 401, causing the positioning rod 401 to move upward along the vertical rod 2, leaving a space for placing the screen 3. After the screen 3 is placed, push the positioning rod 401 to move vertically along the outer wall of the vertical rod 2 so that the bottom end of the positioning rod 401 contacts the top end of the screen 3. At this time, the limit block 403 will also enter the inner side of a limit groove 408 again to limit the movement of the positioning rod 401, thereby completing the limitation of the screen 3. At this time, the screening machine 1 can be used to screen the screen 3, which is convenient for quickly positioning the screen 3 and further improves the working efficiency.

[0045] Please refer specifically to Figures 1 - 3, there are two limiting blocks 403, and the two limiting blocks 403 are respectively fixed on the outer wall of the pressing rod 402 and the end of the movable rod 407. Rotating grooves for the movable block 405 to rotate are formed at the ends of the movable rod 407 and the pressing rod 402. A sliding groove for the axial movement of the pressing rod 402, the limiting block 403, and the movable rod 407 is formed on the inner wall of the positioning rod 401. The inner side of the limiting groove 408 matches the outer wall of the limiting block 403. There are multiple limiting grooves 408, and the multiple limiting grooves 408 are evenly distributed on the outer wall of the vertical rod 2.

[0046] In this embodiment: with this structure, when the pressing rod 402 axially moves into the positioning rod 401, the moving pressing rod 402 synchronously drives the limiting block 403 to move. The moving limiting block 403 will apply a squeezing force to the end of the spring 404. When the limiting block 403 disengages from the inner side of the limiting groove 408, the end of the limiting block 403 will abut against the outer wall of the vertical rod 2 until the positioning rod 401 is moved again to align the limiting block 403 with the limiting groove 408. Through the elastic thrust of the spring 404, the limiting block 403 is synchronously driven to snap into the inner side of the limiting groove 408, completing the quick limiting of the positioning rod 401.

[0047] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
