DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] As Figure 1As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A sand sample collection device for geophysical and geochemical exploration includes a base plate 1 arranged in a square frame shape, and a vertical frame 2 arranged in an inverted U shape and fixed to the base plate 1. It also includes a drilling mechanism 3, which is set on the top of the vertical frame 2 and can automatically lift and lower to drill the sand sample. It also includes a sand sample collection mechanism 4, which is set at the other end of the vertical frame 2 and can automatically dig and collect the drilled sand sample. It also includes a sieve filter mechanism 5, which is set on the base plate 1 to facilitate sieving the sand sample to a specified particle size. A camera 6 is fixed at the top edge of the vertical frame 2 to facilitate taking pictures of the sampling point for archiving.

[0024] like Figures 2-3 As shown, the drilling mechanism 3 includes a telescopic cylinder 7 fixedly connected to the top of both sides of the support frame 2. The telescopic cylinder 7 has a slider 8 slidably connected to the top wall of the support frame 2 at its telescopic end. The top wall of the support frame 2 has a slot that slidably connects to the slider 8, which can limit and support the slider 8. A fixed frame 9 is fixedly connected to the bottom of the slider 8. A threaded rod 10 is rotatably connected between the top and bottom walls of the fixed frame 9. A lifting motor 11 for driving the threaded rod 10 is fixedly installed on the top wall of the fixed frame 9. A nut-equipped bracket 12 is threadedly connected to the threaded rod 10 and slidably connected to both sides of the fixed frame 9. Each wall is provided with an opening that is slidably connected to the nut-supported bracket 12. The nut-supported bracket 12 automatically slides along the opening to adjust its height. A support box 13 is fixedly connected to the bottom of the nut-supported bracket 12. A drilling motor 14 is fixedly installed on the bottom wall of the nut-supported bracket 12. The output end of the drilling motor 14 is connected to a transmission gear 15 that is rotatably connected to the top and bottom walls of the support box 13. The two ends of the transmission gear 15 are meshed with oppositely arranged driven gears. A drill bit 16 is fixedly installed at the bottom of the transmission gear 15, located below the support box 13. The meshing and rotation of each set of transmission gears 15 drives the rotation of each set of drill bits 16, which can drill and sample a large area of ​​rock strata.

[0025] like Figure 4 As shown, the sand sample collection mechanism 4 includes another set of sliders 8 with a lifting cylinder 17 fixedly connected to the bottom wall. The extension end of the lifting cylinder 17 is connected to a connecting seat 18 with an inverted U-shape. A double-headed screw 19 is rotatably connected between the two side walls of the connecting seat 18. A drive motor 20 for driving the double-headed screw 19 to rotate is fixedly installed on one side wall of the connecting seat 18. A guide rod 21 parallel to the double-headed screw 19 is fixedly installed between the two side walls of the connecting seat 18. A nut seat 22 is threadedly connected to the double-headed screw 19. The nut seat 22 is slidably connected to the guide rod 21. The guide rod 21 can limit the nut seat 22 to move in a straight line. A collection clamp 23 with a right-angled triangular side is fixedly installed at the bottom of the nut seat 22. The relative movement of the collection clamp 23 can dig out and collect the drilled sand sample.

[0026] like Figure 2 ,4 As shown, the filter sieve mechanism 5 includes a collection box 24 at one end of the base plate 1. Slide rails 25 are fixedly connected to the two side walls of the collection box 24. A filter sieve box 26 is slidably connected to the slide rails 25. A fixed seat 27 is fixedly provided on one side wall of the collection box 24. An eccentric wheel 28 is rotatably connected between the two side walls of the fixed seat 27. A filter sieve motor 29 that drives the eccentric wheel 28 to rotate is fixedly provided on one side wall of the fixed seat 27. The eccentric wheel 28 and the filter sieve motor 29 are eccentrically set. The eccentric rotation of the eccentric wheel 28 can intermittently push the drill bit 16 to slide, so that the sand sample inside can be automatically filtered. A support plate 30 is fixedly provided on the other side wall of the collection box 24. A connecting spring 31 is fixedly connected to the support plate 30. A push plate 32 that fits against one side wall of the filter sieve box 26 is provided at the other end of the connecting spring 31. The extension and retraction of the connecting spring 31 can push the filter sieve box 26 to slide back and forth.

[0027] In practical use, the user moves the device to a convenient location for sand sample collection, turns on camera 6 to take pictures of the sand sample sampling points and archive them, activates the telescopic cylinder 7 at one end to extend it, causing the slider 8 to slide along the slot at the top of the stand 2, and stops the telescopic cylinder 7 when the drill bit 16 moves to the middle of the base plate 1. Then, the drilling motor 14 is turned on to drive the various sets of transmission gears 15 to mesh and rotate, and the various sets of drill bits 16 at the bottom will rotate accordingly. The lifting motor 11 is turned on to make it rotate forward, causing the threaded rod 10 to rotate forward, and the nut-mounted frame 12 moves along both sides of the fixed frame 9. The opening slides downwards, causing the rotating drill bit 16 to descend and drill for soil and rock sampling. After sampling, the lifting motor 11 is activated to reverse, causing the drill bit 16 to rise and detach from the soil and rock. The telescopic cylinder 7 is then activated to retract, moving the drill bit 16 to one end of the base plate 1. The telescopic cylinder 7 at the other end is then activated to extend, moving the sand sample collection mechanism 4 above the drilled soil and rock. The lifting cylinder 17 is then activated to extend, causing the collection clamp 23 below to descend into the drilled soil and rock. The drive motor 20 is then activated to rotate forward, driving the double-headed screw forward. When the rotation is complete, the two sets of nut seats 22 move relative to each other along the guide rod 21, causing the collecting clamps 23 to move and connect. The two sets of collecting clamps 23 can then gather and collect the drilled sand sample. Then, the lifting cylinder 17 is activated to retract, causing the collecting clamps 23 and the sand sample to rise. At the same time, the telescopic cylinder 7 is activated to retract, causing the collecting clamps 23 to move horizontally to the other end of the base plate 1 and position it above the filter screen mechanism 5. Then, the drive motor 20 is activated to reverse, causing the double-headed screw to reverse. The two sets of collecting clamps 23 then move in opposite directions, releasing the excavated sand sample into the filter screen box. Inside 26, the filter screen motor 29 is turned on, driving the eccentric wheel 28 to rotate eccentrically. The eccentric wheel 28 intermittently hits one side wall of the filter screen box 26, causing the filter screen box 26 to slide along the slide rail 25. The other side wall of the filter screen box 26 then pushes the push plate 32 and causes the connecting spring 31 to extend and retract, thereby driving the filter screen box 26 to slide back and forth along the slide rail 25 to automatically filter the sand sample inside. The filtered sand sample is collected in the collection box 24 below, so that the specified particle size can be retained and collected. The above is the entire usage process of the sand sample collection device used for geophysical and geochemical exploration.
