A sampling device for measuring sediment in desert areas

Abstract

The invention relates to a sampling device for measuring sediment in desert areas, and relates to the technical field of sampling devices. When a sampling mechanism is inserted into loose desert soil, the desert soil will enter a transparent storage tube. After the transparent storage tube is filled, a conical head can be rotated so that two sampling holes on the conical head are not aligned with the two transparent storage tubes, and the upper surface of the conical head seals the two transparent storage tubes, thereby preventing the desert soil in the transparent storage tubes from flowing out during the ascending process of the sampling mechanism, so that the device can be suitable for sampling soil sediment in desert areas. The sampling mechanism can be rotated horizontally and vertically by a rotating mechanism. When the device is placed on the desert ground, the horizontal direction and the vertical direction of the sampling mechanism can be changed by the rotating mechanism, so that the bubble in the bubble level is located at the center of the instrument, and vertical sampling can be performed without the need for workers to rely on experience, thereby improving the sampling success rate of the device.

Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a sampling device used for measuring sediments in desert areas. Background Art

[0002] Desert mainly refers to a barren area where the ground is completely covered with sand, with few plants, little rain and dry air. When studying desert soil and soil where sand plants grow, it is necessary to sample and analyze the soil sediments in the sample site, and then use soil sampling devices.

[0003] Patent publication number CN109030078A discloses a soil sampler. This prior art provides a soil sampler for compacting soil samples to solve the problem that the soil samples in the sampling tube are loose and easily fall out of the sampling port during the taking-out process.

[0004] However, the above prior art has the following technical defects:

[0005] First, this device must pull the sampling tube out of the soil before using the baffle plate to block the sampling port. However, the soil sediments in desert areas are sand and layers of different proportions composed of coarse sand, fine sand, gravel, etc., which makes the desert soil sediments very loose. Even if the desert soil enters the sampling tube, it will quickly flow out of the tube during the rising process of the sampling tube due to its looseness. Before the sampling tube is pulled out, the soil in the tube will be completely lost, and thus this existing technology is not suitable for soil sampling in desert areas.

[0006] Second, during the sampling process, the sampling tube must be inserted vertically into the soil. Vertical sampling can more conveniently measure the depth and layer of the soil, allowing researchers to more easily locate specific soil layers during analysis. However, when staff use this existing technology to take samples, they can only rely on experience to make the sampling tube vertical to the ground. Relying on experience to make the sampling tube vertical will result in a large error, which may cause sampling failure and affect subsequent test results in severe cases.

[0007] In summary, the existing technology still has room for improvement in terms of application to desert ground soil sampling and improving the success rate of soil sampling. Therefore, it is necessary to develop a device that can be applied to soil sampling in desert areas and ensure vertical sampling. Summary of the invention

[0008] In order to solve the above problems, the present application provides a sampling device for sediment measurement in desert areas, which adopts the following technical solution: it includes a mouth-shaped plate, a group of C-shaped frames are symmetrically installed on the upper side of the mouth-shaped plate, and a mounting plate is installed on the upper side of each C-shaped frame.

After the transparent storage tube is filled, the conical head can be rotated so that the two sampling holes on the conical head are not aligned with the two transparent storage tubes, and the upper surface of the conical head seals the two transparent storage tubes. Then, during the rising process of the sampling mechanism, the desert soil in the transparent storage tube is prevented from flowing out, so that the device can be suitable for sampling soil sediments in desert areas.

At this time, the sampling mechanism is just perpendicular to the ground, so vertical sampling can be performed. There is no need for staff to rely on experience for vertical sampling, thereby improving the sampling success rate of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 - Fig.14 Embodiments of the present invention are described in detail.

[0039] The embodiment of the present application discloses a sampling device for measuring sediments in desert areas. When the sampling mechanism is inserted into loose desert soil, the desert soil will enter a transparent storage tube. After the transparent storage tube is filled, the conical head can be rotated so that the two sampling holes on the conical head are not aligned with the two transparent storage tubes, and the upper surface of the conical head seals the two transparent storage tubes. As the sampling mechanism rises, the desert soil in the transparent storage tube is prevented from flowing out, so that this device can be suitable for sampling soil sediments in desert areas.

[0040] Embodiment 1:

[0041] like Figure 1 and Figure 2 , including a mouth-shaped plate 1, the lower side of the mouth-shaped plate 1 is rectangular and is equipped with four pointed pins (not shown in the figure), a group of U-shaped frames 2 are symmetrically installed on the upper side of the mouth-shaped plate 1, and a mounting plate 3 is installed on the upper side of each U-shaped frame 2. A sampling mechanism 4 is arranged between the two mounting plates 3. The two mounting plates 3 are used to install other mechanisms of the device. When in use, the device is placed in a predetermined position, and the four pointed pins of the mouth-shaped plate 1 are inserted into the desert soil to fix the device, and then the sampling mechanism 4 is used to sample the desert sediment.

[0042] like Figure 3-Figure 4 As shown, a driving mechanism 5 is arranged above the sampling mechanism 4, and the driving mechanism 5 includes a moving frame 501, between the inner walls of the moving frame 501, a vertical one-way screw 502 is rotatably installed, and the one-way screw 502 is provided with a threaded seat 503 which is slidably connected to the inner wall of the moving frame 501, and two connecting rods 504 connected to the sampling mechanism 4 are symmetrically installed on the lower side of the threaded seat 503. The rotating one-way screw 502 drives the threaded seat 503 to descend, and the descending threaded seat 503 drives the sampling mechanism 4 to descend through the connecting rod 504.

[0043] like Figure 4 As shown, a C-shaped plate 505 is installed at the upper end of the movable frame 501, the upper end of the one-way screw 502 extends to the upper surface of the movable frame 501 and is installed with a first driving bevel gear 506, a driving motor 507 is installed on the side of the C-shaped plate 505, and a second driving bevel gear 508 meshing with the first driving bevel gear 506 is installed at the driving end of the driving motor 507. The driving motor 507 drives the second driving bevel gear 508 to rotate, and the rotating second driving bevel gear 508 can drive the one-way screw 502 to rotate through the first driving bevel gear 506.

[0044] In summary, the driving motor 507 drives the second driving bevel gear 508 to rotate, and the rotating second driving bevel gear 508 can drive the one-way screw 502 to rotate through the first driving bevel gear 506. The rotating one-way screw 502 drives the threaded seat 503 to descend, and the descending threaded seat 503 drives the sampling mechanism 4 to descend through the connecting rod 504 and insert into the desert sediment for sampling.

[0045] like Figure 5-Figure 7As shown, the sampling mechanism 4 includes a connecting seat 402, a conical head 401 is rotatably mounted on the lower side of the connecting seat 402, and two sampling holes 405 connected to the upper surface are symmetrically provided on the inclined surface of the conical head 401. A threaded hole 406 aligned with each sampling hole 405 is provided on the upper side of the connecting seat 402 just above each sampling hole 405, and each threaded hole 406 is provided with a transparent storage tube 407 matched therewith, and an external thread 408 matched with the threaded hole 406 is provided on the outer surface of the lower end of the transparent storage tube 407. When the sampling mechanism 4 is inserted into the desert soil, as the conical head 401 continues to descend, the desert soil will enter the transparent storage tube 407 through the sampling hole 405.

[0046] like Figure 6 and Figure 8 As shown, a circular tube 403 is installed at the center of the upper side of the connecting seat 402, and an upper plate 404 connected to two connecting rods 504 is installed at the upper end of the circular tube 403. An outer cylinder 409 with the same diameter as the connecting seat 402 is sleeved on the outer side of the upper plate 404. The inner wall of the outer cylinder 409 is rectangular and four groups of rectangular plates 410 are installed. A sliding rod 411 penetrating the upper plate 404 is installed between each group of two rectangular plates 410. The four sliding rods 411 penetrating the upper plate 404 can be used to allow the outer cylinder 409 to slide on the upper plate 404, and the rectangular plates 410 are used to cooperate with the upper plate 404 to limit the upper and lower positions of the outer cylinder 409.

[0047] like Figure 7 and Fig. 9 As shown, two cavities 412 are symmetrically provided inside the upper plate 404, and a corresponding groove 415 is provided on the side of each cavity 412, and a limit plate 413 is slidably provided in the cavity 412, and a spring 414 is provided on one side of the limit plate 413 in the cavity 412, and a clamping member 416 extending into the corresponding groove 415 is installed at the center of the side of the limit plate 413, and two clamping members 416 are pressed inside, and each moving clamping member 416 compresses the spring 414 through the limit plate 413 and also drives the clamping member 416 to move out of the groove 415, so that the fixation of the outer cylinder 409 can be released.

[0048] like Figure 5-Figure 6 As shown, a main rod 417 is rotatably installed inside the center of the one-way screw 502, a rectangular groove 418 is opened inside the main rod 417, a rectangular block 419 matching with it is slidably arranged in the rectangular groove 418, and a sub-rod 420 that passes through the round tube 403 and is fixedly connected to the conical head 401 is installed on the lower side of the rectangular block 419. When the conical head 401 descends, the sub-rod 420 is also driven to descend, and the descending sub-rod 420 drives the rectangular block 419 to slide and descend in the rectangular groove 418.

[0049] like Figure 3 , Figure 5 and Figure 6As shown, the upper end of the main rod 417 extends to the outside of the one-way screw 502 and is installed with a first rotating bevel gear 422. A rotating motor 421 is installed on the other side of the C-shaped plate 505. The driving end of the rotating motor 421 is installed with a second rotating bevel gear 423 meshing with the first rotating bevel gear 422. The running rotating motor 421 drives the main rod 417 to rotate through the second rotating bevel gear 423 and the first rotating bevel gear 422. The rotating main rod 417 drives the conical head 401 to rotate through the rectangular groove 418 and the rectangular block 419 through the auxiliary rod 420.

[0050] In summary, the driving mechanism 5 is used to drive the conical head 401 to descend so that it is inserted into the desert soil sediment. As the conical head 401 continues to descend, the desert soil will enter the transparent storage tube 407 through the sampling hole 405 until the transparent storage tube 407 is filled with soil. Then, the running rotating motor 421 drives the main rod 417 to rotate through the second rotating bevel gear 423 and the first rotating bevel gear 422. The rotating main rod 417 drives the conical head 401 to rotate ninety degrees through the auxiliary rod 420 through the rectangular groove 418 and the rectangular block 419, so that the sampling hole 405 is not aligned with the transparent storage tube 407, and then the upper surface of the conical head 401 is used to close the lower port of the transparent storage tube 407, and then the driving mechanism 5 is used to remove the conical head 401 from the desert soil.

[0051] like Figure 10-Figure 14 As shown, it also includes a rotating mechanism 6, which includes a mouth-shaped frame 601 that is sleeved on the mobile frame 501 and located between the two mounting plates 3, and both sides of the mobile frame 501 are equipped with rotating tables 602 that are rotatably connected to the inner wall of the mouth-shaped frame 601, and both sides of the mouth-shaped frame 601 are equipped with rotating seats 604 that are rotatably connected to the mounting plate 3 on the same side, and the end of the rotating seat 604 passes through the mounting plate 3 and is equipped with a second gear 605. The two rotating tables 602 can allow the mobile frame 501 to rotate horizontally, and the two rotating seats 604 can allow the mobile frame 501 to rotate longitudinally.

[0052] like Fig.12 As shown, two side panels 606 are symmetrically installed on the front side of the mouth-shaped frame 601, and two cross bars 608 are symmetrically installed between the two mouth-shaped frames 601. Slide blocks 609 are slidably arranged on the cross bars 608. A second electric push rod 611 whose end is fixedly connected to a slide block 609 is installed on the side of one of the side panels 606. When the second electric push rod 611 is extended, it can drive the slide block 609 fixedly connected to its end to slide on the cross bar 608.

[0053] like Fig.12As shown, the end of one of the rotating platforms 602 extends to the outer surface of the mouth-shaped frame 601 and is installed with a first gear 603. A gear ring 607 is rotatably installed on the side center of the first gear 603. A movable rack 610 meshing with the gear ring 607 is installed on the side of each slider 609. The moving slider 609 drives the movable rack 610 connected thereto to move, and the moving movable rack 610 drives the other movable rack 610 to move in the opposite direction through the gear ring 607.

[0054] like Fig.12 As shown, the movable rack 610 is installed with a first L-shaped plate 612 near the first gear 603, and the side of the first L-shaped plate 612 is installed with a first arc-shaped rack 613 meshing with the first gear 603. The two movable movable racks 610 drive the two first arc-shaped racks 613 away from each other through the two first L-shaped plates 612, which can drive the two first arc-shaped racks 613 to release the meshing with the first gear 603, so that the movable frame 501 can rotate horizontally.

[0055] like Fig.12 As shown, the end of each movable rack 610 passes through the side plate 606 on the same side and is installed with a second L-shaped plate 614, and the second L-shaped plate 614 is installed with a second arc-shaped rack 615 meshing with the adjacent second gear 605. The two movable movable racks 610 drive the two second arc-shaped racks 615 away from each other through the two second L-shaped plates 614, thereby releasing the meshing of the second gear 605 and allowing the movable frame 501 to cooperate with the mouth-shaped frame 601 to rotate longitudinally.

[0056] like Fig.10 As shown, a bubble level 7 is installed at the center of the upper side of the U-shaped plate 505. The staff fine-tunes the orientation of the movable frame 501 so that the bubble of the bubble level 7 is in the center of the instrument. At this time, the movable frame 501 is oriented vertically, so that the conical head 401 can be vertically inserted into the desert soil, thereby improving the success rate of sampling.

[0057] In summary, when the second electric push rod 611 is extended, it can drive the slider 609 fixedly connected to its end to slide on the cross bar 608, and the moving slider 609 drives the movable rack 610 connected to it to move, and the moving movable rack 610 drives another movable rack 610 to move in the opposite direction through the gear ring 607, and the two moving movable racks 610 drive the two first arc-shaped racks 613 to move away from each other through the two first L-shaped plates 612, so that the two first arc-shaped racks 613 are released from the meshing with the first gear 603, and the two moving movable racks 610 drive the two second arc-shaped racks 615 to move away from each other through the two second L-shaped plates 614, so as to release the meshing with the second gear 605, and then the staff can manually adjust the horizontal and vertical orientations of the moving frame 501 and the conical head 401 until the bubble of the bubble level 7 is in the center of the instrument. At this time, the moving frame 501 is vertically oriented, so that the conical head 401 can be vertically inserted into the desert soil, thereby improving the sampling success rate.

[0058] Embodiment 2:

[0059] Based on the first embodiment, Figure 7 As shown, two through holes 428 are symmetrically opened on the upper side of the connecting seat 402 and are distributed in a rectangular shape with the other two threaded holes 406. The diameter of the through hole 428 is the same as the diameter of the sampling hole 405. The rotating conical head 401 can align the two sampling holes 405 with the two through holes 428.

[0060] like Figure 7 As shown, two first electric push rods 425 are symmetrically installed on the lower side of the upper plate 404, and a special-shaped plate 426 is commonly installed on the lower ends of the two first electric push rods 425. A blocking column 427 is installed on the lower side of the special-shaped plate 426 just above each through hole 428, and the lower end of the blocking column 427 is matched with the inclined surface of the conical head 401. The two first electric push rods 425 are extended to drive the two blocking columns 427 to descend through the two through holes 428 and insert into the two sampling holes 405 until the lower ends of the two blocking columns 427 are flush with the inclined surface of the conical head 401.

[0061] In summary, when it is necessary to sample desert soil sediments of a predetermined depth, the conical head 401 is rotated to align the two sampling holes 405 with the two through holes 428, and the two first electric push rods 425 are extended to drive the two blocking columns 427 to descend through the two through holes 428 and insert into the two sampling holes 405, until the lower ends of the two blocking columns 427 are flush with the inclined surface of the conical head 401, and the two sampling holes 405 are closed. After that, when the conical head 401 is inserted into the desert soil, the desert soil is prevented from entering the sampling hole 405. After being inserted into the predetermined depth, the two first electric push rods 425 are shortened to drive the blocking columns 427 to rise and move out of the sampling hole 405. Then, the conical head 401 is rotated to align the two sampling holes 405 with the two transparent storage tubes 407, and then the conical head 401 is descended to achieve sampling of the desert soil of a predetermined depth.

[0062] Working principle of the present invention:

[0063] S1. Placement of the device: Place the device at a predetermined sampling location in the desert. Specifically, after the staff determines the sediment sampling location in the desert area, the staff places the device on the soil at the predetermined location and inserts the four pointed pins of the mouth-shaped plate 1 into the soil to fix the device.

[0064] S2. Release the fixation, release the lateral rotation fixation of the movable frame 501 and the longitudinal rotation fixation of the mouth-shaped frame 601. Specifically, the second electric push rod 611 extends and drives the slider 609 fixedly connected to its end to slide on the cross bar 608. The moving slider 609 drives the movable rack 610 connected to it to move. The moving movable rack 610 drives another movable rack 610 to move in the opposite direction through the gear ring 607. The two moving movable racks 610 drive the two first arc-shaped racks 613 away from each other through the two first L-shaped plates 612, so that the two first arc-shaped racks 613 are released from meshing with the first gear 603, and also drive the two second arc-shaped racks 615 away from each other through the two second L-shaped plates 614, so as to release the meshing with the second gear 605.

[0065] S3. Direction adjustment. Adjust the direction of the conical head 401 so that it is vertically facing the desert ground. The staff can manually adjust the lateral and longitudinal directions of the movable frame 501 and the conical head 401 until the bubble of the bubble level 7 is in the center of the instrument. Then the second electric push rod 611 is shortened. Through the above operation, the two first arc-shaped racks 613 and the two second arc-shaped racks 615 are brought close to each other, the two first arc-shaped racks 613 are meshed with the first gear 603, and the two second arc-shaped racks 615 are meshed with the two second gears 605, and the sampling mechanism 4 and the driving mechanism 5 are re-fixed.

[0066] S4, soil sampling, sampling the desert soil below through the driving mechanism 5 cooperating with the sampling mechanism 4. Specifically, the driving motor 507 drives the second driving bevel gear 508 to rotate, and the rotating second driving bevel gear 508 can drive the one-way screw 502 to rotate through the first driving bevel gear 506. The rotating one-way screw 502 drives the threaded seat 503 to descend, and the descending threaded seat 503 drives the conical head 401 to descend through the connecting rod 504 and the upper plate 404 to insert it into the desert soil sediment. As the conical head 401 continues to descend, the desert soil will enter the transparent storage tube 407 through the sampling hole 405 until the transparent storage tube 407 is filled with soil.

[0067] S5. Port closure. The conical head 401 is rotated to close the ports below the two transparent storage tubes 407. Specifically, the running rotating motor 421 drives the main rod 417 to rotate through the second rotating bevel gear 423 and the first rotating bevel gear 422. The rotating main rod 417 drives the conical head 401 to rotate ninety degrees through the auxiliary rod 420 through the rectangular groove 418 and the rectangular block 419, so that the sampling hole 405 is not aligned with the transparent storage tube 407, and then the upper surface of the conical head 401 is used to close the lower port of the transparent storage tube 407. Then, the driving motor 507 is driven to drive the second driving bevel gear 508 to reverse, so that the conical head 401 can be removed from the desert soil.

[0068] S6, the structure rotates, so that the sampling mechanism 4 rotates 180 degrees to face upward. Specifically, the second electric push rod 611 extends through S2 to release the fixation of the mouth-shaped frame 601, and then the mouth-shaped frame 601 is rotated 180 degrees around the rotating seat 604 and the mounting plate 3 to face upward. Then the driving motor 507 runs to drive the second driving bevel gear 508 to rotate through S3 to make the conical head 401 rise, increase the distance between the conical head 401 and the movable frame 501, and turn off the driving motor 507 after the distance is greater than the length of the outer cylinder 409.
