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 collection and shaping device. Background Art

[0002] At present, in the open-pit mine drilling operation, rock cuttings are often scattered freely around the blasthole, and these rock cuttings are usually used as blasthole filling materials. The traditional method relies on manual use of shovels to dig out the rock cuttings near the blasthole mouth, the main purpose of which is to prevent the rock cuttings from the blasthole mouth from falling into the blasthole, thereby avoiding reducing the hole depth.

[0003] However, the manual processing method has the following main defects: 1. High labor intensity and low efficiency. The work mainly relies on manual cleaning with a shovel, which is not only labor-intensive and inefficient, but also exposes the workers directly to a high-dust working environment, which is not conducive to the occupational health protection of workers; 2. It is easily affected by strong winds, which increases costs. In strong winds, rock cuttings are easily blown away by the wind, especially when the wind speed is high. Rock cuttings may be blown away directly, resulting in the loss of filling materials in the blasthole.

[0015] As described above, the present invention has the following beneficial effects: 1. The present application can process the rock cuttings generated in the drilling operation of the open-pit mine, greatly reducing the demand for manual labor. It can improve the operation efficiency and significantly reduce the labor cost. In the present application, through the spatial position adjustment mechanism, the mechanical arm can accurately adjust the spatial position of the positioning axis, so as to ensure that the positioning axis can be accurately inserted into the blasthole, block it, and prevent the rock cuttings on the periphery of the blasthole from falling back into the blasthole, affecting the subsequent operation. In the present application, the design of the extrusion mechanism makes the rock cuttings compacted after contacting the inner peripheral surface of the annular cover, and the rock cuttings form a wall of a certain strength after compaction, which can reduce the inflow of rainwater or prevent the strong wind from blowing dust into the blasthole. In the present application, the collection mechanism can rotate and push the distal rock cuttings to gather toward the center of the blasthole, which helps to gather the rock cuttings scattered at the far end of the top of the blasthole for use in subsequent operations. The present application also improves the safety of the operation. Compared with manual handling of rock cuttings, the use of the mechanical arm reduces the direct contact between personnel and rock cuttings, thereby reducing the damage of rock cuttings to on-site workers.

[0016] 2. In this application, the rock cuttings pile is reinforced by spraying a solidifying liquid, which reduces environmental pollution caused by 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 the rock cuttings are sprayed, a temporary protective layer is formed on the surface of the rock cuttings. When it is subsequently used as a backfill material, this protective layer can be destroyed and used together as a backfill material. In this application, the solidifying liquid is pressurized by a pressurizing component to ensure that the solidifying liquid can be evenly sprayed on the surface of the rock cuttings, thereby significantly improving the overall stability and wind resistance of the rock cuttings pile. In this application, the design of the spraying component adopts a double spraying plate (a first spraying plate and a second spraying plate), and the two are arc-shaped and are located on both sides of the target rock cuttings. This design enables the solidifying liquid to cover the rock cuttings 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 cuttings piles. In the present application, a switch valve is provided at one end of the connecting hose to facilitate the control of the delivery and stop of the solidifying liquid. In the present application, a stirring component is designed to fully stir the solidifying liquid. The stirring blade can prevent the sedimentation of the bottom material, and the first stirring rod and the second stirring rod can fully stir the solidifying liquid, which can reduce the usage of each component of the stirring liquid and save resources.

[0060] In this embodiment, a second controller is also included, and the pressurizing component 10, the stirring component 11 and the spraying component 12 are connected to the second controller by signal, and the second controller is used to control the operation of the pressurizing component 10, the stirring component 11 and the spraying component 12. In this embodiment, the second controller can be another single-chip microcomputer or PLC, and the second controller is fixedly mounted on the mounting plate 9.

[0061] In the above embodiment, the design of the spray assembly adopts a double spray plate (a first spray plate and a second spray plate), and the two are arc-shaped and are respectively located on the two sides of the annular rock debris pile. This design enables the solidifying liquid to cover the rock debris pile more comprehensively, avoiding the problem of uneven reinforcement caused by the blind area of ​​spraying. The first spray plate is connected in a flippable manner, which further increases the flexibility and adaptability of spraying, ensuring that the solidifying liquid can be accurately sprayed according to the shape and height of different rock debris piles. In this application, the rock debris pile is reinforced by spraying the solidifying liquid, which reduces the environmental pollution caused by the flying rock debris and reduces the risk of rock debris falling into the blasthole. The solidifying liquid can be accurately formulated according to the actual situation. After the rock debris is sprayed, a temporary protective layer is formed on the surface of the rock debris. When the rock debris pile is used as a backfill material in the future, this protective layer can be destroyed, and the rock debris pile and the protective layer are used together as backfill materials. The solidifying liquid can be cement mortar, which is sprayed on the surface of the rock pile in a certain ratio and then solidified, so that the surface of the rock pile forms a whole. When the wind blows, the surface of the rock pile will not be scattered due to the wind. When the rock pile needs to be used as backfill material, the cement mortar as a protective layer can be destroyed with a shovel, and it can be mixed with the rock pile and used together as backfill material.

[0062] Working principle of the shaping device: The first spray plate 17 and the second spray plate 18 are adjusted to be compatible with the inner and outer annular walls of the annular rock cuttings. The sealing cover is opened, the ingredients of the cement mortar are loaded, the switch valve is closed, and the eighth power member is started. The eighth power member drives the cross rotating column 1102 to rotate. The rotation of the cross rotating column 1102 causes the stirring blade 1103 to rotate. 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 causes the first rotating sleeve rod 1104 and the second rotating sleeve rod 1105 to rotate. 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 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.

[0063] In summary, the present invention first uses a collection device to collect and compact the rock cuttings scattered around the blasthole, and finally uses a shaping device to spray a solidifying liquid to reinforce the surface of the rock cuttings. The collection device and the shaping device can be installed on different carriers without affecting their independent use. When the construction of a certain local construction area of ​​the rock cuttings is completed, the carrier is moved to the next construction area for construction.
