[0044] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0045] See also Figure 1-Figure 5 , the present invention provides a spraying device for open-pit mine drilling cuttings pile, comprising a mounting plate 9, a pressurizing assembly 10, a stirring assembly 11 and a spraying assembly 12;

[0046] The stirring assembly 11 is fixedly connected to the mounting plate 9, and the stirring assembly 11 is used to stir the solidifying liquid;

[0047] The pressurizing assembly 10 is connected to the stirring assembly 11, and is used to apply pressure to the uniformly stirred solidifying liquid so that the solidifying liquid is sprayed onto the surface of the rock cuttings. The spraying assembly 12 is connected to the stirring assembly 11, and is used to spray the solidifying liquid toward the target rock cuttings.

[0048] The spray assembly 12 includes a connecting seat 13, a third connecting rod 14, a fourth connecting rod 15, a connecting hose 16, a first spray plate 17, a second spray plate 18 and a first hydraulic cylinder 19;

[0049] One end of the connecting hose 16 is connected to the stirring assembly 11 for conveying the solidifying liquid. The other end of the connecting hose 16 is divided into two and communicates with the first spray plate 17 and the second spray plate 18. The end of the connecting hose 16 connected to the stirring assembly 11 is provided with a switch valve; the switch valve can be a conventional manual valve for on and off, or a solenoid valve electrically connected to the controller; in this embodiment, a solenoid valve is preferred; the first hydraulic cylinder 19 can be an electric hydraulic cylinder, which is electrically connected to the controller for easy use and operation.

[0050] The first spray plate 17 and the second spray plate 18 are arc-shaped. The liquid outlet of the first spray plate 17 is provided on the arc-shaped arch surface, and the liquid outlet of the second spray plate 18 is provided on the arc-shaped concave surface. The first spray plate 17 is reversibly connected to one end of the fourth connecting rod 15. The other end of the fourth connecting rod 15 is fixedly connected to the second spray plate 18. The second spray plate 18 is fixedly connected to the connecting seat 13. The connecting seat 13 is hinged to the third connecting rod 14 and is driven to rotate by the first hydraulic cylinder 19. The third connecting rod 14 is connected to the mounting plate 9. In this embodiment, the mounting plate 9 can be mounted on the vehicle body or the actuator end of the robot arm; when mounted on the vehicle body, the vehicle body performs a circular circumferential motion around the annular rock debris pile; when mounted on the actuator end of the robot arm, the actuator end of the robot arm performs a circular circumferential motion around the annular rock debris pile. In this embodiment, the pressurizing component 10 may be a blower, and the motor speed of the blower is controlled by a controller. By changing the motor speed of the blower, the flow rate of the solidifying liquid during spraying is adjusted.

[0051] During open-pit mining operations, blasthole drilling generates a large amount of rock debris. This debris is discharged by the drilling rig around the top of the blasthole or splashed at the distal end. These debris are manually collected and stacked around the blasthole, forming a ring-shaped debris pile. This application is used to reinforce this ring-shaped 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 annular debris pile. This design allows the solidifying liquid to more comprehensively cover the debris pile, avoiding uneven reinforcement caused by blind spots. The first spray plate is reversibly connected, further increasing the flexibility and adaptability of the spray, ensuring that the solidifying liquid can be precisely sprayed according to the shape and height of the debris pile. In this application, by spraying solidifying liquid to reinforce the debris pile, environmental pollution caused by flying debris is reduced, and the risk of debris falling into the blasthole is minimized. The solidifying liquid can be precisely formulated based on the actual situation. After spraying the cuttings, a temporary protective layer forms on the surface. Later, when the cuttings pile is used as backfill, this protective layer can be broken down, and both the cuttings pile and the protective layer can be used together as backfill. The solidifying liquid can be made of cement mortar. This mortar, mixed in a specific ratio, is sprayed on the surface of the cuttings pile and solidifies, forming a single, cohesive surface. This prevents the surface from dispersing in the wind. When the cuttings pile is needed as backfill, the protective layer of cement mortar can be broken down with a shovel and mixed with the cuttings pile to be used together as backfill.

[0052] In this embodiment, Figure 2 , further comprising a second hydraulic cylinder 20. The first spray plate 17 is hingedly connected to one end of the fourth connecting rod 15. The other end of the fourth connecting rod 15 is fixedly connected to the second spray plate 18. One end of the second hydraulic cylinder 20 is hingedly connected to the fourth connecting rod 15, and the other end of the second hydraulic cylinder 20 is hingedly connected to the first spray plate 17. In this embodiment, the second hydraulic cylinder 20 is an electric hydraulic cylinder, which is electrically connected to a controller for ease of operation.

[0053] In this embodiment, Figure 2 and Figure 3 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 spray plate 18 includes a fourth spray piece 1801, a fifth spray piece 1802, and a sixth spray piece 1803. The fourth spray piece 1801 and the fifth spray piece 1802 are connected by a plurality of second telescopic tubes, and the fifth spray piece 1802 and the sixth spray piece 1803 are also connected by a plurality of second telescopic tubes.

[0054] The top ends of the first spraying piece 1701, the second spraying piece 1702, and the third spraying piece 1703 are respectively hinged to one end of the corresponding fourth connecting rod 15, and the other end of each fourth connecting rod 15 is fixedly connected to the fourth spraying piece 1801, the fifth spraying piece 1802, and the sixth spraying piece 1803, respectively. A second hydraulic cylinder 20 is provided corresponding to the fourth connecting rod 15, with one end hinged to the corresponding fourth connecting rod 15 and the other end hinged to the corresponding spraying piece. 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;

[0055] It also includes a ninth motor 21, a first rotating page 22 and a second rotating page 23;

[0056] 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. The first rotating page 22 is connected to the second rotating page 23 through a rope, and the rope is in an "8" shape. The second rotating page 23 is fixedly connected to the fourth spray piece 1801, and the second rotating page 23 is rotatably connected to the connecting seat 13.

[0057] In this embodiment, the first telescopic tube and the second telescopic tube are both bellows. In this embodiment, the ninth motor 21 can be a servo motor electrically connected to a controller, which controls the rotation of the servo motor, thereby controlling the rotation of the first rotating page 22 and the second rotating page 23.

[0058] The specific tasks are as follows:

[0059] 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. This rotation of the worm gear drives the turbine gear, which in turn drives the first rotating leaf 22. The first rotating leaf 22 then drives the second rotating leaf 23 via a rope wound in a figure-8 pattern. The sixth and fourth spray plates 1803 and 1801 are attached to the first and second rotating leaves 22 and 23, respectively, enabling rotation of the sixth and fourth spray plates 1803 and 1801. The adjustable design of the sixth and fourth spray plates 1803 and 1801 aims to closely conform to the inner and outer annular walls of the cuttings. Furthermore, during the formation of the inner and outer annular walls of the cuttings, their tilt varies due to manual manipulation. To address this, the first spray plate 17 can be flipped relative to the second spray plate 18 to increase adaptability. This 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.

[0060] In this embodiment, Figure 4 and Figure 5 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;

[0061] The top of the mixing box 1101 is open, and the top surface in the middle is fixedly connected to the end gear;

[0062] One end of the first rotating sleeve 1104 is fixedly connected to the eighth gear 1106, and the other end is fixedly connected to the first bevel gear 1108; one end of the second rotating sleeve 1105 is fixedly connected to the ninth gear 1107, and the other end is fixedly connected to the second bevel gear 1109; the first rotating sleeve 1104, the eighth gear 1106, and the first bevel gear 1108 are symmetrically arranged with the second rotating sleeve 1105, the ninth gear 1107, and the second bevel gear 1109, respectively. The first rotating sleeve 1104 and the second rotating sleeve 1105 are sleeved on the horizontal axis of the cross rotating column 1102;

[0063] 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 controller. The eighth motor can also be a servo motor capable of controlling its rotation rate.

[0064] 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.

[0065] 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.

[0066] This embodiment also includes a shield ring 1116, which is rotatably connected to the mixing box 1101. A through-hole is defined in the peripheral wall of the shield ring 1116, through which the first rotating sleeve 1104 and the second rotating sleeve 1105 pass. In this embodiment, the shield ring 1116 protects the face gear and related components.

[0067] This embodiment further includes a plurality of reinforcing ribs 1117, one end of each of which is fixedly connected to the horizontal axis of the cross-rotating column 1102, and the other end of each of which is fixedly connected to the shield ring 1116. In this embodiment, the design of the reinforcing ribs 1117 allows the shield ring 1116 to rotate synchronously with the cross-rotating column 1102, further enhancing the practicality of the shield ring 1116.

[0068] 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.

[0069] 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.

[0070] In this embodiment, a controller is also included. The pressurizing assembly 10, the stirring assembly 11, and the spraying assembly 12 are connected to the controller by signal. The 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 controller can be a single-chip microcomputer or a PLC controller, and the controller is fixedly mounted on the mounting plate 9.
