Description

TECHNICAL FIELD

[0001] The application relates to the technical field of water and soil conservation devices, in particular to a positioning and marking device for mine restoration. BACKGROUND

[0002] Mining activities have a huge impact on the surrounding ecological environment, and the problem of water and soil loss is particularly prominent. In the process of open mining, a large amount of topsoil and rock is stripped, destroying the original vegetation and soil structure. At the same time, a large number of mine pits and waste accumulation sites formed by mining lack vegetation cover and are easily eroded by rain and wind. At present, a variety of water and soil conservation devices and technologies have been applied to mine restoration. These devices and technologies mainly include the hanging net spraying and seeding lawn planting technology, the construction of planting pool planting technology, the planting technology of planting bag or planting block, etc. These technologies can restore the ecological environment of the mine to a certain extent.

[0003] The existing patent (announcement number: CN221685387U) discloses a water and soil conservation device for mine ecological restoration. The device comprises a first column and a second column located on the right side of the first column and corresponding to the first column. The outer wall of the first column and the second column is provided with an adjusting mechanism. The adjusting mechanism comprises a first movable block, a sliding block and a sliding groove. The sliding groove is opened in the outer wall of the first column and the second column.

[0004] In the above-mentioned scheme, the tape is prevented from being bent by contacting weeds and trees, which can achieve good measurement accuracy. Then, the position is marked by scattering white powder. However, in the above-mentioned scheme, when the white powder is scattered for marking, the scattered powder will gradually expand in area when falling to the ground due to wind factors, which will cause the position of the measurement point to be marked inaccurately, resulting in errors in marking, thereby affecting the accuracy and effect of subsequent planting. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the application provides a positioning and marking device for mine restoration, which has the advantages of accurate positioning and solves the problems raised in the background art.

[0006] To achieve the above object, the application provides the following technical scheme: A positioning marking device for mine repair, comprising two sleeves, the bottom surface of each of the two sleeves is fixedly connected with a marking cone column, the bottom surface of each of the two sleeves is fixedly connected with a powder bucket, the bottom of each of the two powder buckets is provided with four circumferential arrayed material blocking structures, the bottom surface of each of the two powder buckets is fixedly connected with a filter screen, the material blocking structure comprises a connecting rod inserted into the inner wall of the powder bucket, one end of the connecting rod is fixedly connected with an annular blocking block, the outer surface of the annular blocking block is located inside the powder bucket, the other end of the connecting rod is fixedly connected with a first fixed plate, the inner wall of each of the two sleeves is slidingly connected with a pressing block, the upper surface of each of the two pressing blocks is fixedly connected with a connecting column, the outer surface of the connecting column is slidingly connected to the inner wall of the sleeve, and the upper surface of each of the two connecting columns is fixedly connected with a handle.

[0007] Through the above scheme, through the action between the powder bucket, the connecting rod, the annular blocking block, the first fixed plate, the filter screen and the marking cone column, when the sleeve drives the marking cone column to penetrate into the ground to make the powder bucket close to the ground, when the sleeve continues to drive the marking cone column to penetrate into the ground, the powder bucket moves downward, the first fixed plate contacts the ground and drives the connecting rod and the annular blocking block to move upward, at this time, under the action of gravity and the guidance of the annular blocking block, the white powder in the powder bucket can be moved to the space in the middle of the powder bucket, so that the white powder can flow stably to the upper side of the filter screen, and then the white powder can be evenly scattered in a circular ring on the edge of the marking cone column, thereby accurately marking the position of the measured point and improving the accuracy and effect of subsequent planting.

[0008] Further, one side surface of the annular blocking block is a slope, the outer surface of the first fixed plate is sleeved with a spring, and the two ends of the spring are fixedly connected to the upper surface of the first fixed plate and the bottom surface of the powder bucket, respectively.

[0009] Through the above scheme, through the action of the annular blocking block, under the action of the slope on one side surface of the annular blocking block, the slope can move the material in the powder bucket to the space in the middle during the upward movement of the powder bucket, so that the material can flow stably into the upper side of the filter screen, the white powder can be stably scattered on the edge of the marking cone column through the filter screen, and through the action of the spring, when the marking is completed, the sleeve is taken out, at this time, the spring is released from the compression and moves downward under the action of the return force to cover the filter screen with the annular blocking block, thereby avoiding the leakage of white powder.

[0010] Further, the marking cone column is sleeved inside the powder bucket.

[0011] Through the above scheme, by setting up the powder bucket, which is then ring-shaped and fitted onto the marking cone, the powder bucket can accurately mark the position of the marking cone, thus improving the accuracy of the marking.

[0012] Furthermore, two annular support plates are fixedly connected to the outer surfaces of both sleeves, and two symmetrical guide posts are fixedly connected to one side of the two annular support plates that are close to each other. Two symmetrical sliding frames are provided on the outside of the two sleeves, and the outer surfaces of the sliding frames are slidably connected to the outer surfaces of the guide posts.

[0013] The above solution, by setting guide columns, can guide the movement of the sliding frame, thereby ensuring that the sliding frame moves smoothly up and down.

[0014] Furthermore, the outer surfaces of the two guide pillars are provided with equidistant positioning holes, and the outer surfaces of the two sliding frames are provided with two symmetrical limiting mechanisms.

[0015] The above solution, by setting a limiting mechanism, can limit the height of the sliding frame, thereby ensuring the stability of the sliding frame at this height.

[0016] Furthermore, the limiting mechanism includes a rod inserted into the inner wall of the sliding frame, and the outer surface of the rod is inserted into the inner wall of the positioning hole.

[0017] The above solution, through the setting of the insertion rod and positioning hole, when the insertion rod is inserted into the positioning hole, and in conjunction with the different height opening positions of the positioning hole, can limit the different height positions of the sliding frame, ensuring the stability of the sliding frame after the height is adjusted.

[0018] Furthermore, a second fixing plate is fixedly connected to one end of the insertion rod, and a tension spring is sleeved on the outside of the insertion rod. The two ends of the tension spring are respectively fixedly connected to the outer surface of the second fixing plate and the outer surface of the sliding frame.

[0019] The above solution, by setting up a tension spring, can drive the insertion rod to always be inserted into the positioning hole, thereby ensuring the stability of the sliding frame's limiting position.

[0020] Furthermore, a measuring tape is mounted on the outer surface of one of the sliding frames, and a hook is fixedly connected to the outer surface of the other sliding frame.

[0021] With the above solution, by setting up a sliding frame and a measuring tape, the extended end of the measuring tape can be hung on the hook of another sliding frame, which allows for quick connection. When the device is not in use, the hook can be released, thereby disconnecting the two sleeves and facilitating handling.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This positioning and marking device for mine restoration utilizes the interaction between a powder bucket, a connecting rod, an annular block, a first fixing plate, a filter screen, and a marking cone. When the sleeve presses down, it drives the marking cone into the ground, bringing the powder bucket close to the ground. As the sleeve continues to drive the marking cone deeper, the powder bucket moves downwards, and the first fixing plate contacts the ground, pushing the connecting rod and the annular block upwards. Under the influence of gravity and the guidance of the annular block, the white powder inside the powder bucket is moved to the space in the middle of the powder bucket, allowing the powder to flow stably above the filter screen. The white powder then falls evenly in a circular pattern from the filter screen onto the edge of the marking cone, thus accurately marking the position of the measurement point and improving the accuracy and effectiveness of subsequent planting.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a positioning marking device for mine restoration includes two sleeves 1, with marking cones 2 fixedly connected to the bottom surfaces of both sleeves 1. Powder containers 3 are also fixedly connected to the bottom surfaces of both sleeves 1. Each powder container 3 has four circumferentially arrayed material-blocking structures 4 at its bottom, and filter screens 5 are fixedly connected to the bottom surfaces of both powder containers 3. Each material-blocking structure 4 includes a connecting rod 401 inserted into the inner wall of the powder container 3. One end of the connecting rod 401 is fixedly connected to an annular blocking block 402. The outer surface of 402 is located inside the powder bucket 3. The other end of the connecting rod 401 is fixedly connected to the first fixing plate 403. Through the interaction between the powder bucket 3, the connecting rod 401, the annular block 402, the first fixing plate 403, the filter screen 5, and the marking cone 2, when the sleeve 1 is pressed down, it causes the marking cone 2 to penetrate into the ground, making the powder bucket 3 close to the ground. When the sleeve 1 continues to drive the marking cone 2 to penetrate, the powder bucket 3 moves downward, and the first fixing plate 403 contacts the ground. Pushing the connecting rod 401 and the annular block 402 upwards, under the action of gravity and guided by the annular block 402, the white powder inside the powder bucket 3 can be moved to the space in the middle of the powder bucket 3, so that the powder flows stably to the top of the filter screen 5. Then, the white powder is evenly sprinkled in a circular shape from the filter screen 5 onto the edge of the marking cone 2, thereby accurately marking the position of the measurement point and improving the accuracy and effect of subsequent planting. The inner walls of the two sleeves 1 are slidably connected with pressure blocks 6, and the upper surfaces of the two pressure blocks 6 are fixedly connected with connecting columns 7. The outer surfaces of the connecting columns 7 are slidably connected to the inner walls of the sleeves 1, and the upper surfaces of the two connecting columns 7 are fixedly connected with handles 8. By setting the pressure blocks 6, connecting columns 7 and handles 8, moving the handles 8 up and down and pressing down hard when moving downwards can drive the sleeves 1 to move downwards. The sleeves 1 and the marking cone 2 can be moved downwards by the internal downward pressure while the sleeves 1 remain stationary. The overall operation is more convenient and the marking efficiency is improved.

[0032] Please see Figure 1 , Figure 2 and Figure 3One side of the annular block 402 is inclined. A spring 404 is sleeved on the outer surface of the first fixing plate 403. The two ends of the spring 404 are fixedly connected to the upper surface of the first fixing plate 403 and the bottom surface of the powder bucket 3, respectively. By setting the annular block 402, the inclined surface of one side of the annular block 402 can move the material inside the powder bucket 3 to the middle space during the upward movement of the powder bucket 3, so that the material flows stably into the upper part of the filter screen 5, and the white powder can stably pass through the filter screen 5 and fall on the side of the marking cone 2. Furthermore, through the action of the spring 404, after the marking is completed, the sleeve 1 is removed as a whole. At this time, the spring 404 is released from the compression and its return force causes the annular block 402 to move downward, so that the annular block 402 completely covers the filter screen 5, thereby preventing the white powder from leaking.

[0033] Please see Figure 1 and Figure 4 The marking cone 2 is fitted inside the powder hopper 3. By setting the powder hopper 3, the powder hopper 3 is ring-shaped and fitted on the marking cone 2. Thus, the powder hopper 3 can accurately mark the position of the marking cone 2, improving the accuracy of the marking. Two annular support plates 9 are fixedly connected to the outer surfaces of the two sleeves 1. Two symmetrical guide posts 10 are fixedly connected to the side of the two annular support plates 9 that are close to each other. Two symmetrical sliding frames 12 are provided on the outside of the two sleeves 1, and the outer surface of the sliding frame 12 is slidably connected to the outer surface of the guide post 10. By setting the guide post 10, the movement of the sliding frame 12 can be guided, thereby ensuring that the sliding frame 12 moves smoothly up and down. The outer surface of the two guide posts 10 is provided with equidistantly arranged positioning holes 11. The outer surface of the two sliding frames 12 is provided with two symmetrical limiting mechanisms 13. By setting the limiting mechanism 13, the height of the sliding frame 12 can be limited, thereby ensuring the stability of the sliding frame 12 at this height.

[0034] Please see Figure 1 and Figure 4The limiting mechanism 13 includes a rod 1301 inserted into the inner wall of the sliding frame 12. The outer surface of the rod 1301 is inserted into the inner wall of the positioning hole 11. By setting the rod 1301 and the positioning hole 11, when the rod 1301 is inserted into the positioning hole 11 and is positioned at different heights, it can limit the different height positions of the sliding frame 12, ensuring the stability of the sliding frame 12 after height adjustment. One end of the rod 1301 is fixedly connected to a second fixing plate 1302, and a tension spring 1303 is sleeved on the outside of the rod 1301. The two ends of the tension spring 1303 are respectively fixedly connected to the second fixing plate 1302. The outer surfaces of the fixed plate 1302 and the outer surfaces of the sliding frame 12, through the action of the tension spring 1303, can drive the insertion rod 1301 to always be inserted into the positioning hole 11, thereby ensuring the stability of the sliding frame 12. A measuring tape 14 is installed on the outer surface of one sliding frame 12, and a hook is fixedly connected to the outer surface of the other sliding frame 12. Through the action of the sliding frame 12 and the measuring tape 14, the protruding end of the measuring tape 14 can be hung on the hook of the other sliding frame 12, thereby enabling quick connection. When the device is not in use, the hook can be released, thereby disconnecting the two sleeves 1, which facilitates transportation.

[0035] This embodiment of a positioning and marking device for mine restoration utilizes the interaction between a powder bucket 3, a connecting rod 401, an annular block 402, a first fixing plate 403, a filter screen 5, and a marking cone 2. When the sleeve 1 presses down, it drives the marking cone 2 into the ground, causing the powder bucket 3 to be close to the ground. As the sleeve 1 continues to drive the marking cone 2 into the ground, the powder bucket 3 moves downward. Relatively speaking, the first fixing plate 403 contacts the ground and pushes the connecting rod 401 and the annular block 402 upward. At this time, under the action of gravity and guided by the annular block 402, the white powder inside the powder bucket 3 can be moved to the space in the middle of the powder bucket 3, so that the powder flows stably above the filter screen 5. Then, the white powder is evenly scattered in a circular shape from the filter screen 5 onto the edge of the marking cone 2, thereby accurately marking the position of the measurement point and improving the accuracy and effect of subsequent planting.

[0036] The working principle of the above embodiment is as follows: When using this device, one of the sleeves 1 is first placed in a designated position. At this time, pulling the handle 8 causes the connecting column 7 and the pressure block 6 to slide, and pressing the handle 8 down hard causes the pressure block 6 to press down on the sleeve 1 as a whole. At this time, the sleeve 1 can push the marking cone 2 into the ground, making the powder bucket 3 close to the ground. When the sleeve 1 continues to drive the marking cone 2 into the ground, the powder bucket 3 moves downward as a whole. The first fixing plate 403 contacts the ground and pushes the connecting rod 401 and the annular block 402 upward. At this time, under the action of gravity and guided by the annular block 402, the white powder inside the powder bucket 3 can be moved to the space in the middle of the powder bucket 3, so that the powder flows stably to the filter screen 5. Above, white powder is evenly sprinkled in a circular pattern from the filter screen 5 onto the edge of the marking cone 2, thus accurately marking the position of the measurement point. After marking is completed, the sleeve 1 is removed as a whole. At this time, the spring 404 is released from compression and its return force causes the annular block 402 to move downward, so that the annular block 402 covers the filter screen 5, thus preventing the white powder from leaking. Finally, during the marking process, the sliding frame 12 can adjust the height of the measuring tape 14 on the surface of the annular support plate 9, thus preventing weeds from affecting the measuring tape 14. Then, the tension spring 1303 pushes the insertion rod 1301 to always be inserted into the positioning hole 11, thus ensuring the stability of the sliding frame 12.
