Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a stratified sampler. Background Technology

[0002] To analyze the metal content in soil, soil sampling and testing are required. When sampling soil in mines, due to the spatial heterogeneity of soil distribution, multiple samples should be taken from different plots and then mixed into a single composite sample. This will better represent the soil properties of the sampling area.

[0003] Patent publication number CN218766106U discloses a soil sampler, belonging to the field of agricultural soil testing equipment. The soil sampler includes a limiting cylinder, a pedal fixedly connected to the lower end of the limiting cylinder, an insertion tube fixedly connected to the middle of the lower end of the pedal, a chamfered lower end of the insertion tube, and multiple depth lines on the outer side of the insertion tube.

[0004] To address the issue of not being able to determine the soil depth after sampling, existing technology uses samplers that sample and test soil at different depths. However, this method still cannot sample soil at different depths simultaneously, leading to a cumbersome soil sampling process. Utility Model Content

[0005] The purpose of this invention is to provide a stratified sampler to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A layered sampler includes a drilling mechanism with a storage mechanism inside. The drilling mechanism includes a drill bit, a sleeve fixedly connected to the top surface of the drill bit, and three sampling slots on the side of the sleeve. A sampling block is fixedly connected to the side of each sampling slot. A gripping device is fixedly connected to the top of the outer surface of the sleeve, a bearing is fixedly connected to the outer surface of the sleeve, a top plate is fixedly connected to the outer surface of the bearing, and a limit block is movably connected to the top surface of the top plate.

[0008] A further improvement of this utility model is that: a threaded rod is fixedly connected to the bottom surface of the limiting block, one end of the threaded rod penetrates the bottom surface of the top plate and is fixedly connected to the bottom plate, a fixing nut is threadedly connected to the outer surface of the threaded rod, and a ground nail is fixedly connected to the bottom surface of the bottom plate.

[0009] A further improvement of the present invention is that the holding device includes a fixing block, the fixing block is fixedly connected to the top of the outer surface of the sleeve, a grip rod is fixedly connected to the side of the fixing block, the grip rod is fixedly connected to the side of the fixing block, and there are two grip rods, with the other grip rod fixedly connected to the other side of the fixing block.

[0010] A further improvement of this utility model is that: a limiting plate is fixedly connected to the side of the grip, a threaded rotating rod is fixedly connected to one end of the top surface of the fixing block, an anti-detachment block is rotatably connected to the outer surface of the threaded rotating rod, a limiting nut is threadedly connected to the top of the outer surface of the threaded rotating rod, and the limiting nut is tightly attached to the top surface of the anti-detachment block.

[0011] A further improvement of the present invention is that the storage mechanism includes a bottom slider, which is rotatably connected to the inside of the drill bit. A storage box is fixedly connected to the top surface of the bottom slider, a side baffle is fixedly connected to the bottom surface of the storage box, and a top rod is fixedly connected to the top surface of the side baffle.

[0012] A further improvement of this utility model is that: the top rod is rotatably connected inside the sleeve, the anti-detachment block is movably connected to the top surface of the top rod, an increasing rod is fixedly connected to the top surface of the top rod, a rotating handle is fixedly connected to the top of the outer surface of the increasing rod, and a pointing block is fixedly connected to the side of the rotating handle.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides a layered sampler, which employs a drilling mechanism, drill bit, sleeve, sampling groove, sampling block, holding device, fixing block, threaded rotating rod, anti-detachment block, limiting nut, gripping rod, limiting plate, bearing, top plate, ground nail, threaded rod, bottom plate, limiting block, and fixing nut in coordination. By holding the gripping device, the entire device is pressed down, allowing the drill bit to penetrate the bottom surface and insert the entire device into the soil. At this time, the sleeve and sampling groove are both inside the soil. Each sampling groove corresponds to a different layer of soil. The distance between the bottom plate and the top plate can be adjusted by rotating the fixing nut to sample soil at different depths. Similarly, when the base plate contacts the ground, the ground nails will be inserted into the soil to prevent the entire device from shifting. At this time, the holding device can be rotated to make the entire device rotate inside the bearing, driving the sampling block to dig the soil. The soil will fall into the storage mechanism through the sampling groove. The handle holds the entire device, and the limit plate prevents the entire device from slipping out of your hand during use. When the storage mechanism is placed inside the drilling mechanism, the anti-detachment block can be rotated to lock the top surface of the storage mechanism to prevent the storage mechanism from shifting. The position of the anti-detachment block can be fixed by rotating the limit nut, which improves the adaptability of the device.

[0015] 2. This utility model provides a layered sampler, which employs a storage mechanism, a bottom slider, a storage box, a side baffle, a heightening rod, a rotating handle, a pointing block, and a top rod. By placing the entire storage mechanism inside the drilling mechanism and limiting it with an anti-detachment block, when the drilling mechanism presses down the entire device, the rotating handle can be rotated to block the opening of the sampling slot with the back of the side baffle, preventing soil from falling into the storage box during the pressing process. Before the drilling mechanism reaches the designated position for sampling, the rotating handle is rotated to align the opening of the side baffle with the opening of the sampling slot. At this time, the excavated soil will fall into the storage box through the sampling slot for storage, improving the adaptability of the device. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figure 1-4As shown, this utility model provides a layered sampler, including a drilling mechanism 1, a storage mechanism 2 inside the drilling mechanism 1, a drill bit 11, a sleeve 12 fixedly connected to the top surface of the drill bit 11, a sampling groove 13 with three sampling grooves 13 on the side of the sleeve 12, a sampling block 14 fixedly connected to the side of the sampling groove 13, a holding device 15 fixedly connected to the top of the outer surface of the sleeve 12, a bearing 16 fixedly connected to the outer surface of the sleeve 12, a top plate 17 fixedly connected to the outer surface of the bearing 16, a limiting block 111 movably connected to the top surface of the top plate 17, a threaded rod 19 fixedly connected to the bottom surface of the limiting block 111, one end of the threaded rod 19 penetrating the bottom surface of the top plate 17 and fixedly connected to a bottom plate 110, a fixing nut 112 threadedly connected to the outer surface of the threaded rod 19, and a ground nail 18 fixedly connected to the bottom surface of the bottom plate 110.

[0024] In this embodiment, by holding the gripping device 15 and pressing down the entire device, the drill bit 11 can penetrate the bottom surface and insert the entire device into the soil. At this time, the sleeve 12 and the sampling groove 13 are both in the soil. Each sampling groove 13 corresponds to a different layer of soil. The fixing nut 112 can be rotated to adjust the distance between the bottom plate 110 and the top plate 17 so as to sample the soil at different heights. When the bottom plate 110 contacts the ground, the ground nail 18 will be inserted into the soil to prevent the entire device from shifting. At this time, the gripping device 15 can be rotated to make the entire device rotate inside the bearing 16, driving the sampling block 14 to dig the soil. The soil will fall into the storage mechanism 2 through the sampling groove 13.

[0025] Example 2

[0026] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the holding device 15 includes a fixing block 151, which is fixedly connected to the top of the outer surface of the sleeve 12. A gripping rod 155 is fixedly connected to the side of the fixing block 151. The gripping rod 155 is fixedly connected to the side of the fixing block 151. There are two gripping rods 155. Another gripping rod 155 is fixedly connected to the other side of the fixing block 151. A limiting plate 156 is fixedly connected to the side of the gripping rod 155. A threaded rotating rod 152 is fixedly connected to one end of the top surface of the fixing block 151. An anti-detachment block 153 is rotatably connected to the outer surface of the threaded rotating rod 152. A limiting nut 154 is threadedly connected to the top of the outer surface of the threaded rotating rod 152. The limiting nut 154 is tightly attached to the top surface of the anti-detachment block 153.

[0027] In this embodiment, the entire device is held by the grip 155, and the limiting plate 156 prevents the entire device from slipping out of the hand during use. When the storage mechanism 2 is placed inside the punching mechanism 1, the anti-detachment block 153 can be rotated to lock the top surface of the storage mechanism 2, preventing the storage mechanism 2 from being misaligned. The position of the anti-detachment block 153 can be fixed by rotating the limiting nut 154.

[0028] Example 3

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the storage mechanism 2 includes a bottom slider 21, which is rotatably connected to the inside of the drill bit 11. A storage box 22 is fixedly connected to the top surface of the bottom slider 21. A side baffle 23 is fixedly connected to the bottom surface of the storage box 22. A top rod 27 is fixedly connected to the top surface of the side baffle 23. The top rod 27 is rotatably connected to the inside of the sleeve 12. An anti-detachment block 153 is movably connected to the top surface of the top rod 27. An ascending rod 24 is fixedly connected to the top surface of the top rod 27. A rotating handle 25 is fixedly connected to the top end of the outer surface of the ascending rod 24. A pointing block 26 is fixedly connected to the side of the rotating handle 25.

[0030] In this embodiment, by placing the entire storage mechanism 2 inside the drilling mechanism 1 and limiting it with the anti-detachment block 153, when the drilling mechanism 1 presses down the entire device, the handle 25 can be rotated so that the back of the side baffle 23 blocks the opening of the sampling groove 13, preventing soil from falling into the storage box 22 during the pressing process. Before the drilling mechanism 1 reaches the designated position to take a sample, the handle 25 is rotated so that the opening of the side baffle 23 is aligned with the opening of the sampling groove 13. At this time, the excavated soil will fall into the storage box 22 through the sampling groove 13 for storage.

[0031] The working principle of this stratified sampler will be explained in detail below.

[0032] like Figure 1-4As shown, by placing the storage mechanism 2 inside the drilling mechanism 1, rotating the handle 25 causes the back of the side baffle 23 to block the opening of the sampling slot 13, rotating the anti-detachment block 153 to limit the storage mechanism 2, rotating the limiting nut 154 to fix the position of the anti-detachment block 153, rotating the fixing nut 112 to adjust the distance between the bottom plate 110 and the top plate 17 so as to sample soil at different heights, holding the entire device with the handle 155 and pressing down, the drill bit 11 penetrates the bottom surface and inserts the entire device into the soil, when the bottom plate 110... Upon contact with the ground, the ground nail 18 will be inserted into the soil to prevent the entire device from shifting. Rotate the handle 25 so that the opening of the side baffle 23 is aligned with the opening of the sampling slot 13. At this time, the holding device 15 can be rotated to make the entire device rotate inside the bearing 16, driving the sampling block 14 to dig the soil. The soil will fall into the storage box 22 through the sampling slot 13 for storage. After sampling is completed, rotate the handle 25 again to close the opening of the side baffle 23. At this time, the entire device can be taken out, and the soil sample inside the storage mechanism 2 can be easily taken out.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
