The spraying assembly 12 is connected to the stirring assembly 11, and the spraying assembly 12 is used to spray the solidifying liquid toward the target rock cuttings. 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; One end of the connecting hose 16 is connected to the stirring assembly 11 for conveying the solidifying liquid, and the other end of the connecting hose 16 is divided into two and communicated 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 operation.

[0031] The first spray plate 17 and the second spray plate 18 are arc-shaped, the liquid outlet of the first spray plate 17 is arranged on the arc-shaped arch surface, the liquid outlet of the second spray plate 18 is arranged on the arc-shaped concave surface, the first spray plate 17 is connected to one end of the fourth connecting rod 15 in a flippable manner, 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 the connecting seat 13 is driven to rotate by the first hydraulic cylinder 19, and the third connecting rod 14 is connected to the mounting plate 9. In this embodiment, the mounting plate 9 can be installed on the vehicle body, or the execution end of the mechanical arm; when installed on the vehicle body, the vehicle body performs annular circumferential motion around the annular rock debris pile; when installed on the execution end of the mechanical arm, the execution end of the mechanical arm performs annular 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.

[0032] When drilling in an open-pit mine, a large amount of rock cuttings will be generated when drilling blastholes. These rock cuttings are discharged by the drilling rig on the top side of the blasthole or splashed on the far end of the top of the blasthole. These rock cuttings are collected and piled up manually, surrounding the blasthole, so that the gathered rock cuttings form a ring-shaped rock cutting pile. This application is used to reinforce the ring-shaped rock cutting pile. In this application, the design of the spraying assembly adopts a double spraying plate (a first spraying plate and a second spraying plate), and both are arc-shaped and are located on both sides of the annular rock cutting pile. This design enables the solidifying liquid to cover the rock cutting pile more comprehensively, avoiding the problem of uneven reinforcement caused by the blind area of ​​spraying. The first spraying plate is connected in a flippable manner, which further increases the flexibility and adaptability of the spraying, ensuring that the solidifying liquid can be accurately sprayed according to the shape and height of different rock cutting piles. In this application, the rock cutting pile is reinforced by spraying the solidifying liquid, which reduces the environmental pollution caused by the flying rock cuttings and reduces the risk of rock cuttings falling into the blasthole. The solidifying liquid can be precisely formulated according to the actual situation. After spraying the cuttings, a temporary protective layer is formed on the surface of the cuttings. When the cuttings pile is used as backfill material in the future, this protective layer can be destroyed, and the cuttings pile and the protective layer are used together as backfill material. The solidifying liquid can be cement mortar. The cement mortar is sprayed on the surface of the cuttings pile in a certain ratio and solidified, so that the surface of the cuttings pile forms a whole. When encountering wind, the surface of the cuttings pile will not be scattered by the wind. When the cuttings pile needs to be used as backfill material, the cement mortar used as the protective layer can be destroyed with a shovel, and it can be mixed with the cuttings pile and used together as backfill material.

The second hydraulic cylinder 20 is arranged corresponding to the fourth connecting rod 15, one end of which is hinged to the corresponding fourth connecting rod 15, and the other end of which is 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; It also includes a ninth motor 21, a first rotating page 22 and a second rotating page 23; The ninth motor 21 is fixedly installed on the connecting seat 13, and the output shaft of the ninth motor 21 is fixedly connected with a worm gear.

[0036] The specific work is as follows: The output shaft of the ninth motor 21 rotates, driving the worm fixed thereto to rotate, and the worm meshes with the turbine fixed to the first rotating page 22, so the rotation of the worm drives the turbine to rotate, thereby driving the first rotating page 22 to rotate, and the first rotating page 22 drives the second rotating page 23 to rotate through the "8"-shaped rope, and the sixth spraying piece 1803 and the fourth spraying piece 1801 are respectively fixed to the first rotating page 22 and the second rotating page 23, thereby realizing the rotation of the sixth spraying piece 1803 and the fourth spraying piece 1801. The purpose of designing the sixth spraying piece 1803 and the fourth spraying piece 1801 to be adjustable is to fit the annular inner and outer walls of the rock cuttings as much as possible. In addition, when the annular inner and outer walls of the rock cuttings are formed, due to manual operation, the inclination of the inner and outer walls is different. For this reason, the first spraying plate 17 can be flipped relative to the second spraying plate 18 to increase adaptability.

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.
