Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of geotechnical engineering construction equipment, specifically relating to a drilling slag collection device for a charging hole. Background Technology
[0002] Drilling is a crucial process in open-pit blasting and tunnel excavation. This process generates a large amount of drill cuttings. If these cuttings are left to scatter and accumulate, they not only cause severe dust pollution on-site, affecting the health of workers and the operation of equipment, increasing cleanup costs, but also waste resources. In fact, these drill cuttings are excellent hole-filling materials. Efficiently collecting and utilizing these in-situ generated drill cuttings for subsequent hole backfilling can significantly reduce construction dust, improve the working environment, and save on the cost of transporting waste or purchasing external plugging materials, achieving resource recycling and demonstrating significant economic and environmental benefits. Utility Model Content
[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a drilling slag collection device for a charging hole, which can effectively adapt to different drilling angles and achieve dynamic fitting of the hole opening.
[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a multi-link structure, a drilling device, and a slag collection device. The drilling device includes a drilling rig moving base, a drill bit, and a drilling rig beam rail. The multi-link structure is used to drive the movement and angular rotation of the drilling rig beam rail. The drilling rig moving base is movably mounted on the drilling rig beam rail. The drilling rig moving base drives the drill bit to extend from the end of the drilling rig beam rail and perform drilling. The slag collection device includes a slag collection bin and a rotating bin. The slag collection bin is fixed to the end of the drilling rig beam rail. The drill bit passes through the slag collection bin. The slag collection bin is used to collect drill cuttings and has a discharge port at the bottom. The rotating bin has a fan-shaped column structure and is rotatably mounted at the inlet end of the slag collection bin.
[0005] Optionally, a material hole is provided on the rear side of the bottom of the slag collection bin, and the material hole is connected to the discharge port of the slag collection bin. The slag collection device also includes a spiral discharge shaft, which is rotatably disposed in the material hole and at the bottom of the slag collection bin.
[0006] Optionally, the side edge of the rotating chamber is wrapped with a layer of soft rubber strip, and one side of the rotating chamber is attached to the drilling surface during drilling.
[0007] Optionally, the rotation axis of the spiral discharge shaft is parallel to the length direction of the drilling rig beam rail.
[0008] Optionally, the material hole is located at the bottom of the slag collection bin, away from the drill bit output end.
[0009] Optionally, the spiral discharge shaft is driven by an independent drive motor.
[0010] Optionally, the rotating chamber is rotatably connected to the feed end of the slag collection chamber via the central axis of its sector-shaped column structure.
[0011] Optionally, the soft adhesive strip covers the fan-shaped outer arc edge of the rotating chamber and the two straight edges connecting the two ends of the arc edge.
[0012] Optionally, the output end of the multi-link structure is hinged to the middle or end of the drilling rig beam rail.
[0013] Optionally, the drilling rig moving base is moved in coordination with the drilling rig beam rail via a gear and rack mechanism.
[0014] The beneficial effects of this utility model are as follows: By setting up a slag collection bin, drill cuttings are collected and utilized, facilitating subsequent borehole clogging and preventing excessive dust on-site caused by the random scattering of drill cuttings. A rotating bin adapts to different borehole angles, maintaining constant contact with the borehole surface, which is beneficial for drill cuttings collection and prevents excessive drill cuttings from falling out. Further, soft rubber strips conform to uneven borehole surfaces, further enhancing drill cuttings collection capacity and preventing direct impact between the rotating bin and the borehole surface. A spiral discharge structure, through the rotation of the spiral discharge shaft and in conjunction with the material orifice, uniformly mixes and carries the drill cuttings into the slag collection bin's outlet, preventing drill cuttings from getting stuck or clogging the bin.
