Description

Technical Field

[0001] The invention relates to the technical field of open-pit mine drilling cuttings, in particular to an open-pit mine drilling cuttings collecting and shaping device. Background Art

[0002] During current open-pit drilling operations, rock debris often scatters freely around the blastholes. These debris are often used as blasthole filling material. Traditionally, this method relies on manual shoveling of the debris near the blasthole mouth, primarily to prevent it from falling into the blasthole itself, thereby reducing the hole depth.

[0003] However, the manual processing method has the following main defects:

[0004] 1. High labor intensity and low efficiency. This work mainly relies on manual cleaning with a shovel. Not only is the work intensity high and the efficiency low, but the workers are also directly exposed to a high dusty working environment, which is not conducive to the occupational health protection of workers.

[0005] 2. Susceptible to strong winds, increasing costs. In windy conditions, rock cuttings are easily blown away, especially at high wind speeds. These cuttings can be blown away, leaving the blastholes without fill material. In such cases, the miner can only ship in fine sand or clay for blasthole filling, increasing mining costs.

[0053] As described above, the present invention has the following beneficial effects:

[0054] 1. The present invention can process rock cuttings generated during open-pit mining operations, significantly reducing the need for manual labor. This improves operational efficiency and significantly reduces labor costs. In the present invention, a spatial position adjustment mechanism allows a robotic arm to precisely adjust the spatial position of the positioning shaft, ensuring that the shaft can be accurately inserted into the blasthole and sealed, preventing rock cuttings from the periphery of the blasthole from falling back into the blasthole and impacting subsequent operations. The design of the extrusion mechanism in the present invention compacts the rock cuttings upon contact with the inner circumference of the annular hood. After compaction, the rock cuttings form a wall of a certain strength, reducing the inflow of rainwater or preventing strong winds from blowing dust into the blasthole. In the present invention, a collection mechanism can rotate and push the distal rock cuttings toward the center of the blasthole, helping to collect rock cuttings scattered at the distal end of the blasthole for easier utilization in subsequent operations. The present invention also improves operational safety. Compared to manual handling of rock cuttings, the use of a robotic arm reduces direct contact between personnel and rock cuttings, thereby reducing the risk of rock cuttings harming on-site workers.

[0055] 2. This application reinforces rock debris piles by spraying a solidifying liquid, reducing environmental pollution caused by flying debris and the risk of debris falling into blastholes. The solidifying liquid can be precisely adjusted based on actual conditions. After being sprayed on the debris, it forms a temporary protective layer on the surface. This protective layer can be broken down and subsequently used as backfill. This application applies pressure to the solidifying liquid through a pressurizing assembly, ensuring that it is evenly sprayed onto the surface of the debris, significantly improving the overall stability and wind resistance of the debris pile. The spray assembly design utilizes dual arc-shaped spray plates (a first spray plate and a second spray plate), located on either side of the target debris. This design ensures more comprehensive coverage of the debris pile with solidifying liquid, avoiding uneven reinforcement caused by blind spots. The first spray plate is reversible, further increasing spray flexibility and adaptability, ensuring precise spraying of the solidifying liquid according to the shape and height of the debris pile. This application features an on / off valve at one end of the connecting hose to facilitate control over the delivery and stopping of the solidifying liquid. This application also incorporates a stirring assembly that thoroughly agitates the solidifying liquid. The stirring blades prevent sedimentation at the bottom, while the first and second stirring rods ensure thorough agitation of the solidifying liquid, reducing the amount of each component of the stirring liquid and conserving resources.

This is prior art and will not be described in detail. In this embodiment, the base 301 can be mounted on an external vehicle body for easy transportation. In this embodiment, the spatial position adjustment mechanism 3 is used to adjust the spatial position of the positioning shaft 1 so that it can be accurately inserted into the blasthole.

[0095] In this embodiment, Figure 5 and Figure 6 , the reciprocating drive assembly includes a sixth motor 411, a third gear 412, a fourth gear 413 and a fifth gear 414;

[0096] The fourth gear 413 and the fifth gear 414 are fixedly connected and coaxially arranged. The fourth gear 413 and the fifth gear 414 are rotatably mounted on the positioning shaft 1. The fourth gear 413 is meshed with the third gear 412. The third gear 412 is driven to rotate by the sixth motor 411. The sixth motor 411 is fixedly mounted on the second rotating frame 401.

[0100] The electromagnets are fixedly connected to their corresponding racks, and the adsorption members are fixedly connected to their corresponding connecting rods;

[0101] A plurality of first springs are also provided at the rotation points of each rack and the corresponding connecting rod;

[0102] When the electromagnet is de-energized, the elastic force of the first spring causes the collecting plate to contact the ground;

[0103] When the electromagnet is energized, it attracts the suction element, overcoming the elastic force of the first spring to create a gap between the collection plate and the ground. In this embodiment, the sixth motor 411 utilizes a forward and reverse servo motor, combined with a PLC or single-chip microcomputer. This controls the reciprocating rotation of the sixth motor 411, driving the rack, which in turn drives the connecting rod, which in turn drives the collection plate. After the collection plate has moved back and forth, collecting the debris within the left and right range of the far end of the blasthole, it is necessary to rotate the collection plate vertically. To do this, the servo control of the sixth motor 411 can be temporarily disconnected. This allows the output shaft of the sixth motor 411 to rotate freely. The fifth motor 402 can then be used to rotate the first gear 403, which in turn drives the second turret 401. The second turret 401 then drives the sixth motor 411, the rack, the connecting rod, and the collection plate, thereby adjusting the collection plate's orientation. Alternatively, the sixth motor 411 can be fixedly mounted to the positioning shaft 1. Likewise, when the collecting plate needs to rotate, the servo control of the sixth motor 411 is temporarily disconnected.

[0104] In this embodiment, a position detection mechanism is also included for controlling the on and off of the electromagnet;

[0105] like Figure 11 , the position detection mechanism includes a first photodetector 7, a second photodetector 8 and a first controller;

[0106] The first photodetector 7 and the second photodetector 8 are signal-connected to the first controller, the first controller is electrically connected to the electromagnet, and the first photodetector 7, the second photodetector 8 and the first controller are fixedly mounted on the second rotating frame 401;

[0107] When the first photoelectric detector 7 detects that the rack has retracted to the limit position, the first photoelectric detector 7 transmits a signal to the first controller, and the first controller controls the electromagnet to engage;

[0108] When the second photodetector 8 detects that the rack is extended to the limit position, the second photodetector 8 transmits a signal to the first controller, and the first controller controls the electromagnet to disconnect. In this embodiment, the first controller can be a PLC or a single-chip microcomputer. In this embodiment, an L-shaped shielding member is provided on the side of the rack. When the rack is retracted to the limit position, the L-shaped shielding member blocks the first photodetector 7. After the first controller detects this signal, it energizes the electromagnet, thereby causing the electromagnet to attract the adsorption member; when the rack is extended to the limit position, the L-shaped shielding member blocks the second photodetector 8. After the first controller detects this signal, it deenergizes the electromagnet, thereby causing the elastic force of the first spring to cause the collecting plate to contact the ground;

[0109] In this embodiment, Figure 10 The first collecting plate 405 includes an arc-shaped plate 4051 and a baffle 4052; one end of the arc-shaped plate 4051 is fixedly connected to the connecting rod, and the other end is serrated and in contact with the ground. The center of the arc-shaped plate 4051 is oriented toward the central axis of the positioning shaft 1, and the baffle 4052 is connected to the side of the arc-shaped plate 4051 away from the axis of the positioning shaft 1. In this embodiment, the bottom edge of the arc-shaped plate 4051 has a serrated blade, which can easily cut into the scattered rock debris pile. The width of the arc-shaped plate 4051 is designed according to the range of rock debris scattered around common blast holes, and the general width is about 1.2-1.5 meters. The baffle 4052 is set at the rear edge of the arc-shaped plate 4051 to prevent the rock debris from escaping during the collection operation. In this embodiment, the connection between the baffle 4052 and the arc-shaped plate 4051 can be a fixed connection or a detachable connection via bolts and nuts.

[0110] In this embodiment, Figure 3 , the squeezing mechanism 5 includes a flexible bag 501, a second spring 502, a flexible plate and a rigid plate 503;

[0111] The flexible bladder 501 wraps around the outer circumference of the positioning shaft 1. The positioning shaft 1 is provided with a pipeline connected to the flexible bladder 501. The pipeline is used to introduce gas / liquid. One end of the pipeline is connected to the flexible bladder 501, and the other end extends to the top of the positioning shaft 1 and is connected to an external gas / liquid injection device.

[0112] At least two detachable rigid plates 503 are sleeved on the outer circumference of the flexible bladder 501. The rigid plates 503 are slidably connected to the top of the annular cover 2. The rigid plates 503 are provided with an annular through-groove 5031. The flexible plates are embedded in the annular through-groove 5031 and slidably connected to the rigid plates 503. Two adjacent flexible plates are connected by a plurality of second springs 502.

[0113] When the flexible bag 501 is expanded by the introduction of gas / liquid, it abuts against the rigid plate 503 and slides away from the center, and the flexible plate fills the gap between the two adjacent rigid plates 503;

[0114] When the flexible bag 501 releases gas / liquid and contracts, the elastic force of the second spring 502 causes the flexible plate to contract, so that the rigid plate 503 slides toward the center. In this embodiment, the design of the extrusion mechanism allows the rock chips to be compacted after contacting the inner circumference of the annular cover. After compaction, the rock chips form a wall of a certain strength, which can reduce the inflow of rainwater or prevent strong winds from blowing dust into the blasthole. In this embodiment, the flexible bag 501 can be made of rubber material, the rigid plate 503 can be made of steel plate, and the flexible plate can be made of wear-resistant material or steel sheet. The purpose of using steel sheet is that the steel sheet can be deformed and the steel plate is not easy to deform. When the steel plate moves radially outward, most of the rock chips are squeezed and shaped by the steel plate, and the remaining rock chips contact the flexible plate and are squeezed and shaped. Another purpose of providing the flexible plate is to protect the outer surface of the flexible bag 501.

[0115] In this embodiment, a channeling mechanism 6 is further included, which is connected to the positioning shaft 1 and is used to form a channel for the rock debris in the peripheral area of ​​the annular cover 2.

Figure 12 The canal opening mechanism 6 includes a first rotating frame 601, a sixth gear 602, a seventh gear 603, a seventh motor 604, a scraper 605, a push plate 606 and a telescopic cylinder 607;

The body of the seventh motor 604 is fixedly connected to the positioning shaft 1. The scraper 605 is fixedly connected to the first rotating frame 601. The fixed end of the telescopic cylinder 607 is fixedly connected to the first rotating frame 601, and the telescopic end of the telescopic cylinder 607 is fixedly connected to the push plate 606. In this embodiment, the push plate 606 is located behind the scraper 605 in the direction of rotation. In this embodiment, the scraper 605 is arc-shaped and is located on the outer circumference of the annular cover 2. In this embodiment, the output shaft of the seventh motor 604 rotates, driving the seventh gear 603 to rotate. The seventh gear 603 then drives the sixth gear 602 to rotate. The first turret 601 rotates along with the sixth gear 602. The first turret 601 drives the scraper 605 to excavate a circular ditch for the rock debris. Once the circular ditch is formed, the telescopic cylinder 607 is activated, extending the telescopic cylinder 607 and driving the push plate 606. The push plate 606 pushes the rock debris, forming a "straight" ditch. The "straight" ditch connects to the circular ditch, thereby facilitating the drainage of rainwater. In this embodiment, the push plate 606 can be a multi-stage telescopic cylinder.

[0117] In the above-described embodiment, the collection device can process rock debris generated during open-pit mining operations, significantly reducing the need for manual labor. This improves operational efficiency and significantly reduces labor costs. A spatial position adjustment mechanism allows the robotic arm to precisely adjust the spatial position of the positioning shaft, ensuring accurate insertion into the blasthole and sealing it, preventing rock debris from the periphery of the blasthole from falling back into the blasthole and impacting subsequent operations. The design of the extrusion mechanism compacts the rock debris upon contact with the inner surface of the annular shield. This compaction forms a strong wall, reducing the inflow of rainwater and preventing strong winds from blowing dust into the blasthole. The collection mechanism rotates and pushes distal rock debris toward the center of the blasthole, helping to collect scattered rock debris at the distal end of the blasthole for easier utilization during subsequent operations. This also improves operational safety. Compared to manual rock debris handling, the use of a robotic arm reduces direct contact with rock debris, thereby minimizing the risk of damage to on-site workers.

After the ditch is dug, the device is removed.

[0124] In this embodiment, the first spray plate 17 includes a first spray piece 1701, a second spray piece 1702, and a third spray piece 1703. The first spray piece 1701 and the second spray piece 1702 are connected by a plurality of first telescopic tubes, and the second spray piece 1702 and the third spray piece 1703 are also connected by a plurality of first telescopic tubes.

The second hydraulic cylinder 20 is used to drive the first spraying piece 1701, the second spraying piece 1702, and the third spraying piece 1703 to flip;

[0126] It also includes a ninth motor 21, a first rotating page 22 and a second rotating page 23;

[0127] The ninth motor 21 is fixedly mounted on the connecting seat 13, and the output shaft of the ninth motor 21 is fixedly connected to a worm, and the sixth spray piece 1803 is fixedly connected to the first rotating page 22. The first rotating page 22 is rotatably mounted on the connecting seat 13, and the first rotating page 22 is fixedly provided with a turbine engaged with the worm.

[0129] The specific tasks are as follows:

[0130] The output shaft of the ninth motor 21 rotates, driving the worm gear attached to it. The worm gear meshes with the turbine gear attached to the first rotating leaf 22. Therefore, the rotation of the worm gear drives the turbine gear, thereby driving the first rotating leaf 22.

The sixth spray plate 1803 and the fourth spray plate 1801 are attached to the first rotating leaf 22 and the second rotating leaf 23, respectively, thereby enabling the sixth spray plate 1803 and the fourth spray plate 1801 to rotate. The purpose of designing the sixth spray plate 1803 and the fourth spray plate 1801 to be adjustable is to ensure that they conform to the inner and outer annular walls of the rock debris as closely as possible. In addition, when the inner and outer annular walls of the rock debris are formed, their inner and outer walls have different degrees of inclination. To this end, the first spray plate 17 can be flipped relative to the second spray plate 18 to increase adaptability. The flipping action is achieved by extending and retracting the second hydraulic cylinder 20. When in use, the liquid outlet of the first spray plate 17 faces the inner wall of the annular rock cuttings, and the liquid outlet of the second spray plate 18 faces the outer wall of the annular rock cuttings.

[0131] In this embodiment, Figure 17 and Figure 18 The stirring assembly 11 includes a stirring box 1101, a cross rotating column 1102, a stirring blade 1103, a first rotating sleeve 1104, a second rotating sleeve 1105, an eighth gear 1106, a ninth gear 1107, a first bevel gear 1108, a second bevel gear 1109, a third bevel gear 1110, a fourth bevel gear 1111, a first stirring rod 1112, a second stirring rod 1113, a sealing cover 1114 and an eighth power member;

[0132] The top of the mixing box 1101 is open, and the top surface in the middle is fixedly connected to the end gear;

The first rotating sleeve 1104 and the second rotating sleeve 1105 are sleeved on the horizontal axis of the cross rotating column 1102;

[0134] The eighth gear 1106 and the ninth gear 1107 are both engaged with the end gear of the mixing box 1101. The stirring blade 1103 is fixed to the bottom end of the vertical shaft of the cross-rotating column 1102. The top end of the cross-rotating column 1102 is transmission-connected to an eighth power member, which is connected to the mixing box 1101. The eighth power member includes a transmission belt and an eighth motor. The eighth motor transmits power through the transmission belt to rotate the cross-rotating column 1102. The eighth motor is fixedly connected to the mixing box 1101 and is also electrically connected to the second controller. The eighth motor can also be a servo motor capable of controlling its rotation rate.

[0135] The first stirring rod 1112 and the second stirring rod 1113 are rotatably mounted on the horizontal axis of the cross-rotating column 1102. The central axes of the first stirring rod 1112 and the second stirring rod 1113 are perpendicular to the horizontal axis of the cross-rotating column 1102. The top ends of the first stirring rod 1112 and the second stirring rod 1113 are fixedly connected to the third bevel gear 1110 and the fourth bevel gear 1111, respectively. The third bevel gear 1110 and the fourth bevel gear 1111 are meshed with the first bevel gear 1108 and the second bevel gear 1109, respectively.

[0136] The sealing cover 1114 is connected to the mixing box 1101 and is used to seal the mixing box 1101. The mixing box 1101 is connected to the pressurizing assembly 10. A rubber sealing ring is embedded on the side of the sealing cover 1114 that contacts the mixing box 1101. One end of the sealing cover 1114 is hinged to the mixing box 1101, and the other end is movably connected to the mixing box 1101 through a fastener. Figure 5 The fastener is hook-shaped. When the sealing cover 1114 squeezes the sealing ring to cover the mixing box 1101, the hook-shaped fastener buckles the sealing cover 1114, thereby completing the cover.

[0137] In this embodiment, a shielding ring 1116 is further included. The shielding ring 1116 is rotatably connected to the mixing box 1101. The peripheral wall of the shielding ring 1116 is provided with a through-wall hole for the first rotating sleeve 1104 and the second rotating sleeve 1105 to pass through. In this embodiment, by designing the shielding ring 1116, the end gear and related components can be protected. In this embodiment, a reinforcing rib 1117 is further included. There are multiple reinforcing ribs 1117. One end of the multiple reinforcing ribs 1117 is fixedly connected to the horizontal axis of the cross rotating column 1102, and the other end is fixedly connected to the shielding ring 1116. In this embodiment, by designing the reinforcing ribs 1117, the shielding ring 1116 can rotate synchronously with the cross rotating column 1102, further increasing the practicality of the shielding ring 1116.

[0138] In this embodiment, the outer circumferences of the first stirring rod 1112 and the second stirring rod 1113 are both provided with spiral protrusions. The radial dimensions of the spiral protrusions of the first stirring rod 1112 decrease from bottom to top, while the radial dimensions of the spiral protrusions of the second stirring rod 1113 increase from bottom to top. In this embodiment, by providing the outer circumferences of the first stirring rod 1112 and the second stirring rod 1113 with spiral protrusions, the radial dimensions of the spiral protrusions of the first stirring rod 1112 decrease from bottom to top, while the radial dimensions of the spiral protrusions of the second stirring rod 1113 increase from bottom to top, when the cross-rotating column 1102 rotates circumferentially, it drives the first stirring rod 1112 and the second stirring rod 1113 to rotate. The spiral protrusions of the first stirring rod 1112 cause the stirring liquid to move from bottom to top, while the second stirring rod 1113 causes the stirring liquid to move from top to bottom, forming a reflux ring in the vertical plane, thereby achieving a better stirring effect. While the first stirring rod 1112 and the second stirring rod 1113 rotate on their own, the circumferential rotation of the cross rotating column 1102 is superimposed, so that the overall stirring effect is greatly improved.

[0139] In this embodiment, the cross-section of the stirring blades 1103 is a right-angled trapezoid with hypotenuse. In this embodiment, the stirring blades 1103 can scrape sediment from the bottom to thoroughly mix it with the solution. In this embodiment, there can be multiple stirring blades 1103, arranged circumferentially around the vertical axis of the cross-shaped rotating column 1102. In this example, two stirring blades are shown.

[0140] In this embodiment, a second controller is also included. The pressurizing assembly 10, the stirring assembly 11, and the spraying assembly 12 are connected to the second controller by signal. The second controller is used to control the operation of the pressurizing assembly 10, the stirring assembly 11, and the spraying assembly 12. In this embodiment, the second controller can be another single-chip microcomputer or a PLC. The second controller is fixedly mounted on the mounting plate 9.

[0141] In the above-mentioned embodiment, the spray assembly utilizes dual arc-shaped spray plates (a first spray plate and a second spray plate), positioned on either side of the annular debris pile. This design allows the solidifying liquid to more comprehensively cover the debris pile, avoiding uneven reinforcement issues caused by blind spots. The first spray plate is reversibly connected, further enhancing spraying flexibility and adaptability, ensuring precise application of the solidifying liquid to the shape and height of different debris piles. In this application, the solidifying liquid is sprayed onto the debris pile to reinforce it, reducing environmental pollution caused by flying debris and the risk of debris falling into the blasthole. The solidifying liquid can be precisely adjusted based on actual conditions. After spraying the debris, a temporary protective layer forms on the surface of the debris. This protective layer can be removed when the debris pile is later used as backfill, allowing both the debris pile and the protective layer to serve as backfill. The solidifying liquid can be cement mortar. After being sprayed on the surface of the rock debris pile and solidified in a specific proportion, the surface of the rock debris pile becomes a single entity. This prevents the surface from being scattered by wind. When the rock debris pile needs to be used as backfill, the protective cement mortar can be broken with a shovel and mixed with the rock debris pile to be used as backfill.

[0142] Working principle of the shaping device:

[0143] Adjust the first spray plate 17 and the second spray plate 18 to adapt to the inner and outer ring walls of the annular rock debris. Open the sealing cover, add the ingredients of the cement mortar, close the switch valve, and start the eighth power member. The eighth power member drives the cross rotating column 1102 to rotate. The rotation of the cross rotating column 1102 rotates the stirring blade 1103. The rotation of the cross rotating column 1102 drives the shielding ring 1116 to rotate synchronously. The rotation of the cross rotating column 1102 also rotates the first rotating sleeve rod 1104 and the second rotating sleeve rod 1105. The rotation of the first rotating sleeve rod 1104 and the second rotating sleeve rod 1105 respectively drives the first bevel gear 1108 and the second bevel gear 1109 rotate, the first bevel gear 1108 and the second bevel gear 1109 respectively rotate the third bevel gear 1110 and the fourth bevel gear 1111, the third bevel gear 1110 and the fourth bevel gear 1111 rotate respectively to rotate the first stirring rod 1112 and the second stirring rod 1113, thereby stirring the various ingredients of the cement mortar. After sufficient stirring, close the sealing cover, open the switch valve, start the pressurizing component 10, and the cement mortar is sprayed out from the nozzle.

[0144] In summary, the present invention first uses a collection device to collect and compact the rock debris scattered around the blasthole, and finally uses a shaping device to spray a solidifying fluid to reinforce the surface of the rock debris. The collection device and shaping device can be installed on different carriers, allowing them to be used independently. When a localized area of ​​rock debris is completed, the carrier is moved to the next area.
