Description

Technical Field

[0001] This invention belongs to the field of soil separation technology, and specifically relates to a soil separation device for geological exploration. Background Technology

[0002] In geological exploration, soil sampling and analysis are required. Since some analytical parameters have specific requirements regarding soil particle size, soil separation is often performed during sampling. Currently, the common separation method involves surveyors holding a circular sieve and shaking it back and forth at a certain frequency. However, this method is physically demanding and increases the workload for surveyors. Therefore, to address these issues, we propose a soil separation device for geological exploration. Summary of the Invention

[0003] To overcome the problems existing in related technologies, the present invention discloses a soil separation device for geological exploration.

[0004] To achieve the above objectives, one technical solution adopted by the present invention is:

[0005] A soil separation device for geological exploration includes a drum, a drum screen, an elastic element, a shaft support, a rotating frame, and a handle assembly;

[0006] The roller includes a first cylinder and a first ring plate. There are two first ring plates, and the two first ring plates are respectively fixed to the two axial ends of the first cylinder.

[0007] The cylindrical screen includes a second cylindrical body and a second ring plate. The second cylindrical body has a plurality of screen holes on its circumferential surface. There are two second ring plates, which are respectively fixed to the two axial ends of the second cylindrical body.

[0008] The second cylinder is fitted inside the first cylinder. The two ends of the elastic element are respectively connected to the outer wall of the second cylinder and the inner wall of the first cylinder. There are multiple elastic elements, which are evenly distributed on the circumference of the first cylinder to tighten the second cylinder and suspend it inside the first cylinder.

[0009] The shaft support includes a shaft body and a first connecting member. The first connecting member has two sets. The two sets of first connecting members are respectively connected to both ends of the shaft body and respectively connected to two first ring plates. Both ends of the shaft body have protrusions on their circumferential surfaces.

[0010] The rotating frame includes two rotating frames, and the two rotating frames are respectively rotatably connected to two first ring plates.

[0011] The handle assembly includes two slide rods, each connected to one of the two rotating frames. The inner end of each slide rod points towards the shaft. The minimum distance between the center of the shaft and its circumference is M. The maximum distance between the center of the shaft and the protrusion is N. The distance between the inner end of the slide rod and the center of the shaft is H. The distance H is less than the distance N and greater than or equal to the distance M.

[0012] Furthermore, a discharge port is provided on one side of the roller, and a cover that is detachably connected to the roller is provided at the discharge port.

[0013] Furthermore, the rotating frame also includes a second connecting member, which connects the two rotating frames and is located on the outside of the roller.

[0014] Furthermore, the handle assembly also includes a third connector that connects between the two slide bars.

[0015] Furthermore, the handle assembly also includes two handles, which are located on opposite sides of the slide bar.

[0016] Furthermore, the rotating frame also includes a sliding cylinder and a first locking assembly. There are two sliding cylinders, which are respectively fixedly connected to the two rotating frames. The sliding rod is slidably connected to the two sliding cylinders respectively. When the sliding rod slides relative to the sliding cylinder, the value of the distance H will change.

[0017] The first locking assembly has two components, which are respectively disposed on the upper side of the two slide cylinders. Each of the two slide rods has a first locking groove that matches the first locking assembly. When the first locking assembly locks the slide rod in conjunction with the first locking groove, the slide rod will not be able to slide relative to the slide cylinder. In this state, the distance H is less than the distance N and greater than or equal to the distance M.

[0018] Furthermore, the first locking assembly includes a first sleeve connected to and communicating with the slide cylinder and a first locking bolt slidably fitted inside the first sleeve. The length of the first locking bolt is greater than the depth of the first locking groove, and the upper end of the first sleeve is closed.

[0019] Furthermore, the rotating frame also includes a second locking assembly, of which there are two. The two second locking assemblies are respectively disposed on the lower side of the two slide cylinders. Both slide rods are provided with a second locking groove that matches the second locking assembly. When the second locking assembly locks the slide rod in conjunction with the second locking groove, the slide rod will not be able to slide relative to the slide cylinder. In this state, the distance H is greater than the distance N.

[0020] Furthermore, the second locking assembly includes a second sleeve connected to and communicating with the slide cylinder, and a second locking bolt slidably fitted within the second sleeve. The length of the second locking bolt is greater than the depth of the second locking groove, and the lower end of the second sleeve is closed.

[0021] Furthermore, the upper end of the first sleeve and the lower end of the second sleeve are respectively sealed by a first sealing bolt and a second sealing bolt.

[0022] This invention discloses a soil separation device for geological exploration. The soil separation device has two operating modes. When soil sieving is required, it can be switched to sieving mode, in which the soil can be efficiently sieved by pushing the device to roll, saving time and effort. When it needs to be moved, it can be switched to moving mode, so that the user can push it to roll smoothly on the ground. It is highly portable and convenient for surveyors to use in outdoor exploration. Attached Figure Description

[0039] The invention will now be further described with reference to the accompanying drawings.

[0040] Reference Figures 1-13 As shown, a soil separation device for geological exploration in this embodiment includes a drum 1, a drum screen 2, an elastic element 3, a shaft support 4, a rotating frame 5, and a handle assembly 6.

[0041] In this embodiment, the roller 1 includes a first cylinder 11 and two first ring plates 12, which are respectively fixed to the two axial ends of the first cylinder 11. The two first ring plates 12 and the first cylinder 11 will enclose a storage space for storing the screened soil.

[0042] In this embodiment, the cylindrical sieve 2 includes a second cylindrical body 21 and a second annular plate 22. The second cylindrical body 21 has a plurality of sieve holes 211 on its circumferential surface. There are two second annular plates 22, which are respectively fixed to the two axial ends of the second cylindrical body 21. The two second annular plates 22 and the second cylindrical body 21 enclose a screening space for storing soil to be screened.

[0043] In this embodiment, the second cylinder 21 is fitted inside the first cylinder 11. The two ends of the elastic element 3 are connected to the outer wall of the second cylinder 21 and the inner wall of the first cylinder 11, respectively. There are multiple elastic elements 3, specifically four in this embodiment. The four elastic elements 3 are evenly distributed on the circumference of the first cylinder 11 to tighten the second cylinder 21, making it suspended inside the first cylinder 11. Of course, more elastic elements 3 can be added to increase the tightening strength.

[0044] In this embodiment, the shaft support 4 includes a shaft body 41 and two sets of first connecting members 42. The two sets of first connecting members 42 are respectively connected to both ends of the shaft body 41 and respectively connected to two first annular plates 12. In this embodiment, the first connecting members 42 are rod-shaped structures, with six first connecting members 42 in each set, evenly distributed around the shaft body 41. In this embodiment, both ends of the shaft body 41 have protrusions 411 on their circumferential surfaces, with six protrusions 411 at each end, evenly distributed around the circumferential surface of the shaft body 41.

[0045] In this embodiment, the rotating frame 5 includes two rotating frames 51, and the two rotating frames 51 are rotatably connected to the two first ring plates 12 respectively.

[0046] In this embodiment, the handle assembly 6 includes two slide rods 61, which are respectively connected to two rotating frames 51. The inner end of the slide rod 61 points to the shaft 41. The minimum distance between the center of the shaft 41 and its circumference is M, the maximum distance between the center of the shaft 41 and the protrusion 411 is N, and the distance between the inner end of the slide rod 61 and the center of the shaft 41 is H. The distance H is less than the distance N and greater than or equal to the distance M.

[0047] When the inner end of the slide bar 61 is located between two adjacent protrusions 411, that is, when the protrusions 411 are not in contact with each other, the drum screen 2 and the drum 1 will maintain a nearly concentric state under the tensioning action of each elastic element 3.

[0048] When screening the soil, the entire soil separation device is placed upright on the ground via roller 1, keeping roller 1 in a nearly vertical position. The surveyor can control the posture of the entire device through handle assembly 6 to prevent it from tipping over. After completing the above operation, the soil to be screened is placed into the screening space. Soil smaller than the sieve aperture 211 will fall into roller 1, while soil larger than the sieve aperture 211 will remain in the drum sieve 2.

[0049] To improve screening efficiency, the handle assembly 6 can be operated to cause the drum screen 2 to vibrate. Specifically, the handle assembly 6 pushes the drum 1 to roll on the ground. Under the action of ground friction, the drum 1 and the drum screen 2 will rotate relative to the rotating frame 5 (the drum screen 2 is driven to rotate by the drum 1 in conjunction with multiple elastic elements 3), which means they will rotate relative to the slide rod 61. Thus, the shaft 41 will rotate relative to the slide rod 61. When the protrusion 411 on the shaft 41 rotates to abut against the end of the slide rod 61, since the position of the slide rod 61 and the drum 1 remains relatively fixed, and the shaft support 4 is fixed to the drum screen 2, and the drum screen 2 is elastically connected to the drum 1 through multiple elastic elements 3, the shaft 41 will move relative to the slide rod 61 away from its end under the abutment action of the protrusion 411 and the slide rod 61. In this embodiment, the slide rod 61 specifically moves relative to... The shaft 41 is inclined to the upper right. The protrusion 411 abuts against the slide rod 61, which forces the shaft 41 to tilt to the lower left. During this process, the elastic elements 3 on both sides of the shaft 41 in the direction of movement will stretch and contract respectively. After the highest point of the protrusion 411 passes the slide rod 61, the elastic element 3 will pull the shaft 41 back to its original position. In this embodiment, the shaft 41 moves to the upper right. Thus, the shaft 41 completes one reciprocating motion, which is one vibration. The drum screen 2 connected to the shaft 41 will vibrate synchronously. Since the shaft 41 has six protrusions 411 on its side in this embodiment, the surveyor will cause the drum screen 2 to vibrate six times by pushing the drum 1 to rotate once by pushing the handle assembly 6. By repeatedly pushing and pulling the handle assembly 6, the drum screen 2 can continue to vibrate. This can loosen the soil particles in the drum screen 2, promote soil particle stratification, and improve the screening rate to significantly improve the screening efficiency.

[0050] As can be seen from the above separation operation, when the soil separation device screens the soil, the weight of the entire device is supported by the ground. Surveyors do not need to exert any force to support it; they only need to push the device back and forth. Compared with existing screening methods, this greatly reduces labor intensity and is beneficial for outdoor use by surveyors. Furthermore, surveyors can directly push the device to move it on the ground by rolling, thus improving its convenience. It is worth mentioning that screening operations can be performed simultaneously during movement, greatly improving time utilization and, to a certain extent, increasing the efficiency of survey work.

[0051] Furthermore, in this embodiment, a discharge port 13 is provided on one side of the roller 1, and a cover 14 detachably connected to the roller 1 is provided at the discharge port 13. When performing soil separation operations, the discharge port 13 is sealed by the cover 14 to prevent soil leakage, while allowing the roller 1 to form a complete circle, so that the roller 1 can rotate smoothly on the ground.

[0052] In this embodiment, the rotating frame 5 further includes a second connecting member 52, which connects the two rotating frames 5 and is located on the outside of the roller 1. The second connecting member 52 is provided between the two rotating frames 5 to stabilize the connection between them.

[0053] In this embodiment, the handle assembly 6 further includes a third connector 62, which is connected between the two slide rods 61. The third connector 62 is provided between the two slide rods 61 to stabilize the connection between them. This ensures that the two slide rods 61 remain synchronized when rotating relative to the roller 1.

[0054] In this embodiment, the handle assembly 6 further includes two handles 63, which are located on opposite sides of the slide bar 61. This arrangement allows the user to grip the handles 63 to push and pull the entire device, improving the overall operability of the device.

[0055] In this embodiment, the rotating frame 5 also includes a slide cylinder 53 and a first locking assembly 54. There are two slide cylinders 53, which are fixedly connected to two rotating frames 51 respectively. The slide rod 61 is slidably connected to the two slide cylinders 53 respectively. When the slide rod 61 slides relative to the slide cylinder 53, the value of the distance H will change.

[0056] In this embodiment, there are two first locking components 54, which are respectively disposed on the upper side of the two slide cylinders 53. Each slide rod 61 has a first locking groove 64 that matches the first locking component 54. When the first locking component 54 engages with the first locking groove 64 to lock the slide rod 61, the slide rod 61 cannot slide relative to the slide cylinder 53. In this state, the distance H is less than the distance N and greater than or equal to the distance M. This arrangement allows the slide rod 61 to be connected to the rotating frame 5.

[0057] In this embodiment, the first locking assembly 54 specifically includes a first sleeve 541 connected to and communicating with the slide cylinder 53, and a first locking bolt 542 slidably fitted within the first sleeve 541. The length of the first locking bolt 542 is greater than the depth of the first locking groove 64. The upper end of the first sleeve 541 is closed, specifically by a first sealing bolt 543, to facilitate the installation of the first locking bolt 542.

[0058] In this embodiment, the rotating frame 5 also includes a second locking assembly 55. There are two second locking assemblies 55, which are respectively located on the lower side of the two slide cylinders 53. Both slide rods 61 are provided with a second locking groove 65 that matches the second locking assembly 55. When the second locking assembly 55 locks the slide rod 61 in conjunction with the second locking groove 65, the slide rod 61 will not be able to slide relative to the slide cylinder 53. In this state, the distance H is greater than the distance N.

[0059] In this embodiment, the second locking assembly 55 specifically includes a second sleeve 551 connected to and communicating with the slide cylinder 53, and a second locking bolt 552 slidably assembled in the second sleeve 551. The length of the second locking bolt 552 is greater than the depth of the second locking groove 65. The lower end of the second sleeve 551 is closed, specifically by a second sealing bolt 553, so as to install the second locking bolt 552.

[0060] When the slide bar 61 rotates relative to the roller 1 via the rotating frame 5, the first locking component 54 and the second locking component 55 will rotate synchronously. For ease of understanding, this embodiment introduces a coordinate system with the center of the roller 1 as the origin to describe the functions and roles of the first locking component 54 and the second locking component 55.

[0061] When the slide bar 61 is in the first or fourth quadrant, the first locking assembly 54 will be on the upper side, and the second locking assembly 55 will be on the lower side. The first locking bolt 542 will fall downwards due to gravity. If the first locking bolt 542 is aligned with the first locking groove 64, the first locking bolt 542 will be inserted into the first locking groove 64. Since the length of the first locking bolt 542 is greater than the depth of the first locking groove 64, the upper end of the first locking bolt 542 will be inside the first sleeve 541, thus restricting the slide bar 61 from sliding relative to the slide cylinder 53. In this state, the distance H is less than the distance N and greater than or equal to the distance M. That is, in this state, when the handle assembly 6 pushes the drum 1 to rotate, the drum screen 2 inside the drum 1 will shake. Therefore, this state can be used during soil separation. In this state, the second locking bolt 552 will be retracted into the second sleeve 551 under the action of gravity, that is, it will be in contact with the second sealing bolt 553. In this state, the second locking groove 65 is closer to the shaft 41 than the first locking groove 64. In this state, the second locking bolt 552 is not aligned with the second locking groove 65.

[0062] When the slide bar 61 is in the second or third quadrant, the second locking component 55 will be on the upper side, and the first locking component 54 will be on the lower side. The second locking bolt 552 will fall downwards due to gravity. If the second locking bolt 552 is aligned with the second locking groove 65, the second locking bolt 552 will be inserted into the second locking groove 65. Since the length of the second locking bolt 552 is greater than the depth of the second locking groove 65, the upper end of the second locking bolt 552 will be inside the second sleeve 551, thus restricting the slide bar 61 from sliding relative to the slide cylinder 53. In this state, the distance H is greater than the distance N. Thus, when the drum 1, in conjunction with multiple elastic elements 3, drives the drum screen 2 to rotate, the protrusion 411 on the shaft 41 will not abut against the inner end of the slide bar 61, thereby reducing the rotational resistance of the drum 1 and making the drum 1 rotate more smoothly. Therefore, this state can be used when moving the device by rolling to reduce the difficulty of moving the device. In this state, the first locking bolt 542 will be retracted into the first sleeve 541 under the action of gravity, that is, it will be in contact with the first sealing bolt 543. In this state, the first locking bolt 542 is not aligned with the first locking groove 64.

[0063] It is worth mentioning that switching between the two usage modes only requires operating the handle assembly 6. Specifically, taking the switch from screening mode to moving mode as an example, when the handle assembly 6 is in the first quadrant, rotating it counterclockwise to the second quadrant will unlock the first locking assembly 54, and the second bolt 552 of the second locking assembly 55 will abut against the slide rod 61 under gravity. Since the second locking groove 65 is closer to the shaft 41 than the first locking groove 64, the handle assembly 6 can be pulled away from the shaft 41 in this state. When the second locking groove 65 aligns with the second bolt 552, the second bolt 552 will insert into the second locking groove 65 under gravity. Thus, the inner end of the slide rod 61 is locked away from the shaft 41, and the entire device switches to moving mode. In this state, the surveyor can push or pull the entire device to roll and move it on the ground. The operation of switching from moving mode to screening mode is the same as the above operation, and will not be repeated here.

[0064] In summary, this invention discloses a soil separation device for geological exploration. This soil separation device has two operating modes. When soil sieving is required, it can be switched to a sieving mode, in which case pushing the device to roll can efficiently sieve the soil, saving time and effort. When it needs to be moved, it can be switched to a moving mode, so that the user can push it to roll smoothly on the ground. It is highly portable and convenient for surveyors to use in outdoor exploration.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
