[0002] Layered markers are markers buried in different soil layers of the overburden. Within the ground settlement area, markers are buried on the top and bottom slabs of different soil layers and extend to the ground. After stability protection treatment, they are measured in conjunction with other layered markers and bedrock markers to obtain the compression and expansion of different soil layers, thereby calculating the deformation of different soil layers and the total ground settlement.

[0003] When sealing the layered boreholes, the current mainstream method is still for workers to stand next to the borehole and directly put clay balls into the annular gap between the protective pipe and the borehole wall by hand. This method is relatively primitive, and the amount of clay balls put in manually is often difficult to control, often resulting in too many or too few clay balls, leading to poor sealing quality.

[0064] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the invention and are not intended to limit the invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] It should be further noted that the accompanying drawings and embodiments of the present invention mainly describe the concept of the present invention. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0066] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0067] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0068] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0069] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0070] The present invention will now describe a clay ball pressure sensor.

[0071] like Figures 1 to 6 As shown, the present invention provides a clay ball pressure sensor, including a weighing sleeve 310, an isolation plate assembly 320, and a weighing plate 330; the isolation plate assembly 320 is disposed inside the weighing sleeve 310, and the inner walls of the isolation plate assembly 320 and the weighing sleeve 310 form a plurality of weighing cavities 321; the weighing plate 330 is movably disposed on the bottom side of the weighing cavity 321, and the weighing plate 330 has a fan-shaped structure for weighing the clay ball located in the weighing cavity 321; wherein, the weighing plate 330 includes a lower plate 332, an upper plate 333, and a plurality of pressure sensor bodies 334; the upper plate 333 is mounted on the lower plate 332; the plurality of pressure sensor bodies 334 are mounted between the lower plate 332 and the upper plate 333.

[0072] The clay ball pressure sensor provided by this invention, compared with the prior art, includes a weighing sleeve 310, an isolation plate assembly 320, and a weighing plate 330. The isolation plate assembly 320 is disposed inside the weighing sleeve 310 and together with the weighing sleeve 310 forms several weighing chambers 321. The weighing plate 330 is movably disposed on the bottom side of each weighing chamber 321. In use, the clay ball first falls into one of the weighing chambers 321, and then is weighed... The weighing plate 330 weighs the clay balls in the weighing chamber 321. When the preset weight is reached, the weighing plate 330 moves, allowing the clay balls to fall out of the weighing chamber 321. Then, the next weighing chamber 321 is used to weigh the clay balls. This process is repeated until the batch of clay balls is completely released. This clay ball pressure sensor can divide a batch of clay balls into several weighing chambers 321 for weighing, thereby accurately controlling the number of clay balls to be released.

[0073] like Figure 1 and Figure 3 As shown, in a specific embodiment of the clay ball pressure sensor provided in this invention, a first top plate 322 is connected to the isolation plate assembly 320, and a plurality of telescopic rods 340 are hinged on the first top plate 322. The telescopic rods 340 are disposed in the weighing cavity 321. A boss 3321 is provided on the lower plate 332, and the boss 3321 penetrates the upper plate 333. The ends of the telescopic rods 340 are hinged to the boss 3321. A first hinge seat 331 is provided on one side of the lower plate 332, and a plurality of second hinge seats 311 are provided on the inner wall of the weighing sleeve 310. The first hinge seat 331 is mounted on the second hinge seats 311 for hinge connection.

[0074] It is important to note that once the total mass of the clay balls in this batch is determined, they are evenly distributed according to the number of weighing chambers 321, ensuring that the mass of the clay balls in each weighing chamber 321 is equal. When the clay balls are placed into the weighing chamber 321, they will fall onto the weighing plate 330. The weighing plate 330 is equipped with a pressure sensor body 334, which can detect the weight of the clay balls on the weighing plate 330 in real time. One end of the lower plate 332 is hinged to the inner wall of the weighing cylinder. When the clay balls in the weighing chamber 321 reach the preset weight, the output end of the telescopic rod 340 begins to move downward, pushing the boss 3321 to rotate, thereby driving the entire weighing plate 330 to rotate. At this time, the clay balls on the weighing plate 330 will fall out of the weighing chamber 321. The upper plate 333 and the lower plate 332 are fixedly connected, for example, by bolts or screws.

[0075] like Figures 7 to 17As shown, based on the same inventive concept, this application also provides a clay ball dispensing device, including a frame 100, a dispensing hopper 200, the aforementioned clay ball pressure sensor 300, and a flow guiding assembly 400; the dispensing hopper 200 is disposed at the end of the frame 100; the aforementioned clay ball pressure sensor 300 is disposed in the middle of the frame 100 for weighing the clay balls; the flow guiding assembly 400 is rotatably disposed at the lower part of the frame 100 for dispensing the clay balls; wherein, the lower end of the dispensing hopper 200 is provided with a first discharge port, a first discharge pipe 210 is rotatably connected to the first discharge port, a first bending section 211 is provided in the middle of the first discharge pipe 210, a first motor 3221 is provided on the first top plate 322, and a first linkage 3222 is sleeved on the output end of the first motor 3221 and the first discharge pipe 210.

[0076] Compared with the prior art, the clay ball dispensing device provided by this invention mounts the dispensing hopper 200, the aforementioned clay ball pressure sensor 300, and the flow guiding component 400 onto the frame 100. In use, clay balls are fed into the dispensing device through the dispensing hopper 200. The clay balls are grouped by the clay ball pressure sensor 300 and enter the weighing chamber 321. Weighing is then completed in the weighing chamber 321 by the weighing plate 330. When the preset weight is reached, the weighing plate 330 opens, and the clay balls in the weighing chamber 321 fall into the flow guiding component 400, completing the dispensing operation. This clay ball dispensing device is convenient and reliable to use, saving significant labor costs.

[0077] Specifically, clay balls in the feeding hopper 200 pass through the first discharge port and fall into the weighing chamber 321 via the first discharge pipe 210. Once the clay balls in one of the weighing chambers 321 have been weighed, the first motor 3221 starts, driving the first linkage 3222, which is mounted on the output end of the first motor 3221, to rotate. This rotation, in turn, causes the first discharge pipe 210, connected to the first linkage 3222, to rotate and move to the upper side of the next weighing chamber 321, allowing the clay balls to continue falling and being weighed. This process repeats until the batch of clay balls is fully fed.

[0078] like Figures 7 to 9As shown, in a specific embodiment of the clay ball dispensing device provided in this invention, the flow guiding component 400 includes a flow guiding cylinder 410, a dispensing cylinder 420, and a flow guiding element 430. The diameter of the flow guiding cylinder 410 is smaller than the diameter of the dispensing cylinder 420, and the flow guiding cylinder 410 is fixedly disposed inside the dispensing cylinder 420 through the flow guiding element 430. A rotating slide rail 411 is provided around the flow guiding cylinder 410, and a rotating slide rail 110 is provided on the frame 100. The rotating slide rail 110 is disposed inside the rotating slide rail 411. The frame 100 and the flow guiding component 400 are provided with mutually cooperating drive structures 500 for driving the flow guiding cylinder 410 and the dispensing cylinder 420 to rotate.

[0079] It should be noted that when all the clay balls in this batch fall into the dispensing cylinder 420, their distribution within the cylinder 420 will not be very uniform. Therefore, after the clay balls fall into the dispensing cylinder 420, it is necessary to rotate the dispensing cylinder 420 to ensure that the clay balls are evenly distributed within the cylinder 420. Thus, a rotating slide rail 110 is provided on the frame 100, and a rotating slide 411 is provided around the periphery of the guide cylinder 410. When the drive structure 500 is activated, the drive structure will drive the guide cylinder 410 to rotate, and it will always rotate around the rotating slide 411.

[0080] like Figures 7 to 9 As shown, in a specific embodiment of the clay ball dispensing device provided in this invention, the drive structure 500 includes a second motor 510, a gear 520, and teeth 530. The second motor 510 is mounted on a mounting plate 120 on the frame 100, the gear 520 is mounted on the output end of the second motor 510, and the teeth 530 are arranged in a circumferential direction around the dispensing cylinder 420. The gear 520 and the teeth 530 mesh.

[0081] Here, after all the clay balls in this batch have fallen into the dispensing cylinder 420, the second motor 510 is started. The gear 520 and teeth 530 at the output end of the second motor 510 mesh, thereby driving the rotation of the entire flow guiding assembly 400, which in turn evenly disperses the clay balls in the dispensing cylinder 420. Once the clay balls are evenly distributed, the second motor 510 is turned off.

[0082] like Figures 9 to 11 As shown, in a specific embodiment of the clay ball dispensing device provided in this invention, the guide member 430 includes a guide plate assembly 431 and a conical platform 432. The guide plate assembly 431 is provided with a conical mounting area 4311, and the conical platform 432 is fixedly connected to the conical mounting area 4311 on the guide plate assembly 431. The periphery of the guide plate assembly 431 is connected to the guide cylinder 410. The guide plate assembly 431 and the guide cylinder 410 constitute a guide cavity 4312. The conical platform 432 is provided with a support column 4321, and the end of the support column 4321 is connected to the inner wall of the dispensing cylinder 420.

[0083] The conical platform 432 is provided with a first conical surface 4322, a first annular surface 4323 and a second conical surface 4324. The first conical surface 4322, the first annular surface 4323 and the second conical surface 4324 are connected in sequence. The first conical surface 4322 is connected to the conical installation area 4311, and a guide hole 4325 is formed between the first conical surface 4322, the guide plate assembly 431 and the guide cylinder 410. A support column 4321 is provided on the first annular surface 4323 to support the delivery cylinder 420.

[0084] Furthermore, the guide plate assembly 431 is used to further group the falling clay balls, and the conical platform 432 is used to guide the falling clay balls through the guide hole 4325 into the guide cylinder 410. When the clay ball falls from the weighing chamber 321 into the guide assembly 400, it will fall onto the first conical surface 4322 and slide through the guide hole 4325 onto the second conical surface 4324 under its own gravity, thus entering the delivery cylinder 420.

[0085] like Figure 2 and Figure 3 As shown, in a specific embodiment of the clay ball dispensing device provided in this invention, a diversion hopper 312 is provided inside the weighing sleeve 310. A second discharge port is provided at the lower end of the diversion hopper 312. A second discharge pipe 313 is rotatably connected to the second discharge port. A second bending section 3131 is provided in the middle of the second discharge pipe 313. A second top plate 4313 is provided on the guide plate assembly 431. A third motor 43131 is provided on the second top plate 4313. A second linkage 43132 is sleeved on the output end of the third motor 43131 and the second discharge pipe 313.

[0086] Furthermore, once the clay ball in any weighing chamber 321 has been weighed, the weighing plate 330 will open, and the clay ball will fall into the diversion hopper 312, and then through the second discharge hopper and the second discharge pipe 313 into the guide chamber 4312. When the clay ball in the weighing chamber 321 is sent into the guide chamber 4312, the third motor 43131 starts, and the output end of the third motor 43131 drives the second linkage 43132 to rotate, and drives the second discharge pipe 313 connected to the second linkage 43132 to rotate, rotating the second discharge pipe 313 to the upper side of the next guide chamber 4312, continuing to guide the clay balls falling from other weighing chambers 321.

[0087] like Figures 11 to 13As shown, in a specific embodiment of the clay ball dispensing device provided in this invention, the end face of the dispensing cylinder 420 and the end face of the conical platform 432 form a feeding ring opening 421. The end face of the conical platform 432 is provided with a concave platform 440, and a feeding assembly is provided on the concave platform 440. The feeding assembly includes a fourth motor 441, a rotating frame 442, and a rotating ring 443. The fourth motor 441 is mounted on the concave platform 440, the rotating frame 442 is mounted on the output end of the fourth motor 441, and the rotating ring 443 is mounted on the rotating frame 442. The rotating ring 443 is located inside the feeding ring opening 421. The end face of the rotating ring 443 is provided with a plurality of arc-shaped protrusions 4434. The rotating ring 443 includes a main ring 4431 and a secondary ring 4432. The main ring 4431 is provided with a notch 4433, and the secondary ring 4432 is detachably mounted on the notch 4433 of the main ring 4431 by fasteners.

[0088] It is important to note that when clay balls are not needed, the main ring 4431 and the secondary ring 4432 together block the discharge ring opening 421, preventing the clay balls from falling out. When clay balls need to be added, the secondary ring 4432 is removed, exposing the notch 4433 of the main ring 4431. Starting the fourth motor 441 will drive the rotating frame 442 to rotate, which in turn drives the rotating ring 443 to rotate. During the rotation of the rotating ring 443, the clay balls in the discharge cylinder 420 will fall through the notch 4433 and disperse evenly in a spiral pattern. The rotating ring 443 has several arc-shaped protrusions 4434, which will also impact the clay balls in the discharge cylinder 420 during rotation, preventing the clay balls in the discharge cylinder 420 from becoming clogged.

[0089] like Figures 14 to 17 As shown, in a specific embodiment of the clay ball feeding device provided in this invention, a screening component 600 is provided on the feeding hopper 200. The screening component 600 includes a bottom plate 610, a screening box 620, and a vibration structure 630. The bottom plate 610 is provided on the feeding hopper 200 and has a discharge port 611. The screening box 620 is provided on the bottom plate 610 through a plurality of elastic elements 640. A plurality of screening ports 621 are provided on the bottom wall of the screening box 620. The screening ports 621 are opposite to the discharge ports 611. The screening box 620 has an inlet 622 on one side and a feed outlet 623 on the other side. A feed box 650 is installed on one side of the feed outlet 623. The vibration structure 630 is provided on the bottom plate 610 and connected to the screening box 620 to drive the screening box 620 to screen the clay balls.

[0090] The vibration structure 630 includes a fifth motor 631, a first eccentric shaft assembly 632, and a second eccentric shaft assembly 633. The fifth motor 631 is mounted on the base plate 610. The first eccentric shaft assembly 632 is mounted on one side of the screening box 620, and the second eccentric shaft assembly 633 is mounted on the other side of the screening box 620. The first eccentric shaft assembly 632 is provided with a connector 6321, which is connected to the output end of the fifth motor 631. The first eccentric shaft assembly 632 is provided with a first eccentric block 6322, and the second eccentric shaft assembly 633 is provided with a second eccentric block 6321. A third linkage 660 is sleeved on the first eccentric block 6322 and the second eccentric block 6321.

[0091] Before placing the clay balls into the feeding hopper 200, the clay balls need to be screened because some clay balls may stick together. Here, the clay balls are slowly fed into the screening box 620 through the inlet 622. At this time, the fifth motor 631 starts, and the output of the fifth motor 631 drives the connector 6321 of the first eccentric shaft assembly 632 to rotate. The connector 6321 then drives the first eccentric block 6322 to rotate. The first eccentric block 6322 is connected to the second eccentric block 6321 through the third linkage 660, so it also drives the second eccentric block 6321 to rotate. Ultimately, this drives the screening box 620, which is mounted on the first eccentric shaft assembly 632 and the second eccentric shaft assembly 633, to rotate. Figure 14 For example, when the first eccentric shaft group 632 and the second eccentric shaft group 633 rotate counterclockwise, they will drive the screening box 620 to rotate counterclockwise as well. The normally shaped clay balls in the screening box 620 will jump to the left and fall into the discharge port 611 through the screening port 621. The clay balls that are stuck together may be broken up during the jumping process and fall into the discharge port 611 through the screening port 621. The clay balls that are not broken up will continue to jump into the feed box 650, thereby ensuring the sealing effect of the clay balls.

[0092] Based on the same inventive concept, this application also provides a method for sealing layered marker holes, using the aforementioned clay ball delivery device, including the following steps:

[0093] S1: Install the frame 100, feeding hopper 200, the clay ball pressure sensor 300, the flow guiding component 400 and the screening component 600, and place the frame 100 above the layered standard hole that needs to be sealed, so that the rotating ring 443 is aligned with the annular gap between the protective tube and the hole wall.

[0094] S2: Start the first motor 3221, put the clay ball into the screening component 600 for screening, and the screened clay ball falls into the feeding hopper 200 and enters the clay ball pressure sensor 300 mentioned above through the feeding hopper 200.

[0095] S3: The clay ball pressure sensor 300 described above groups and weighs the falling clay balls. The weighed clay balls fall into the flow guiding component 400. The flow guiding component 430 in the flow guiding component 400 groups the clay balls and guides them into the delivery cylinder 420.

[0096] S4: When all the clay balls in this batch fall into the dispensing cylinder 420, start the second motor 510 to drive the flow guiding component 400 to rotate quickly, so that the clay balls in the dispensing cylinder 420 are evenly distributed.

[0097] S5: Remove the secondary ring 4432, start the fifth motor 631, and the clay ball in the delivery cylinder 420 falls down through the notch 4433 on the main ring 4431 to seal the hole.

[0098] Compared with the prior art, the layered marking hole sealing method provided by the present invention uses the above-mentioned clay ball dispensing device. When sealing the layered marking holes with clay balls, it is only necessary to pour the clay balls into the dispensing device and operate the dispensing device to dispense the clay balls to complete the sealing task. The operation is convenient and reliable, and saves a lot of labor costs.
