Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust collection for down-the-hole drilling rigs, in particular to a novel dust collection device for down-the-hole drilling rigs. Background Art
[0002] The dust collector of a down-the-hole drill is a device used to collect and control dust and particles generated during drilling operations. During drilling operations, the drill generates a large amount of dust and particles, which pose a threat to the health of workers and the environment. The dust collector of a down-the-hole drill is used to prevent the dispersion of dust and particles, reducing their impact on the surrounding environment and workers. The dust collector of a down-the-hole drill can effectively reduce the concentration of dust and particles during drilling operations, protecting the health of workers and the cleanliness of the environment.
[0003] In the prior art, various types of dust collection devices for down-the-hole drills used for metal or non-metal mining generally adopt a whole large-area mesh dust hood. The dust collection mesh skin is relatively hard and has the same height at the front and back, so it is only suitable for dust collection on horizontal ground. However, when encountering a slope or an uneven ground, the hard dust collection mesh skin is relatively hard, resulting in a gap at the junction of the dust collection mesh skin and the uneven ground. When the down-the-hole drill is working, dust can easily drift from the gap at the junction of the hard dust collection mesh skin and the uneven ground, ultimately resulting in extremely poor dust collection effect. Dust leakage has a very serious impact on the environment. At the same time, since the old mesh skin is an integral type, if the entire mesh skin is damaged a little, in order to ensure the dust collection effect, the entire mesh skin needs to be replaced, resulting in a large waste of resources and is not conducive to the company's cost control.
[0004] In summary, how to provide a dust collecting device with good compatibility, wide application range and high economy is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0005] In order to solve the above technical problems, the utility model utilizes the self-weight of multiple dust collecting units to move downward and contact closely with the uneven ground, and the net skin is split into each dust collecting unit to reduce the waste of replacement resources. The specific technical solution is as follows:
[0006] A novel dust collecting device for a down-the-hole drilling rig comprises a dust collecting hood shell, which is used to block dust generated during drilling operation and is fixedly mounted on the outer wall of a frame of the drilling rig; and a dust collecting unit, wherein a plurality of the dust collecting units are evenly distributed on the dust collecting hood shell and are slidably connected to the dust collecting hood shell. The plurality of the dust collecting units fall due to their own weight and are close to the ground.
[0007] Preferably, the dust collecting unit comprises a plurality of resin plates slidably connected to the dust collecting cover shell.
[0008] Preferably, a sealing strip is fixedly installed on one end of the resin plate in contact with the ground.
[0009] It can be seen from the above technical solutions that the utility model has the following beneficial effects:
[0010] By setting up resin plates, multiple resin plates come into contact with the uneven ground after falling under their own weight, which greatly improves the tightness of contact with the uneven ground. The sealing strip ensures that the resin plate is in full contact with the ground, ensuring the sealing of dust collection. At the same time, if one of the resin plates is damaged, only the single resin plate needs to be disassembled and replaced, avoiding the situation where the traditional integrated dust collection net needs to be replaced due to damage in one place, thereby improving resource utilization and reducing enterprise cost investment.

[0013] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.
[0014] like Figure 1 As shown, a novel dust collecting device for a down-the-hole drilling rig comprises a dust collecting hood shell 6 for blocking dust generated during the operation of the drilling rig, the dust collecting hood shell 6 being fixedly mounted on the outer wall of the frame of the drilling rig; a dust collecting unit, wherein a plurality of dust collecting units are evenly distributed on the dust collecting hood shell 6 and are slidably connected to the dust collecting hood shell 6, the plurality of dust collecting units fall down due to their own weight and are in close contact with the ground, wherein the dust collecting units surround the outer wall of the drilling rig frame, when the drilling rig is working, the dust collecting units fall down due to gravity, so that each dust collecting unit contacts the ground outside the drilling rig area, the plurality of dust collecting units can be staggered with each other, the bottom ends of different dust collecting units contact the ground at different heights, avoiding the use of an integrated dust collecting net, which results in gaps between the dust collecting net and the slope or uneven ground, thereby affecting the dust collecting effect.
[0015] As an implementation method in this embodiment, the dust collection unit includes a plurality of resin plates 7 slidably connected to the dust cover shell 6. The resin plates 7 are made of a hard material to replace the traditional dust collection net. The plurality of resin plates 7 come into contact with the ground after falling under their own weight, which greatly improves the degree of contact with the uneven ground. At the same time, if one of the resin plates 7 is damaged, only the single resin plate 7 needs to be disassembled and replaced, thereby avoiding the situation where the traditional integrated dust collection net needs to be replaced due to damage in one place, thereby improving the utilization rate of resources and reducing the cost investment of the enterprise.
[0016] As an implementation method in this embodiment, in order to improve the stability of the movement of the resin plate 7, the dust collection unit includes a cylinder 2 fixedly connected to the dust cover housing 6, a piston 3 slidingly connected to the cylinder 2, and a connecting rod 4 fixedly installed on one end of the piston 3, and the other end of the connecting rod 4 is fixedly connected to the corresponding resin plate 7. The piston 3 can move back and forth along the inner wall of the cylinder 2, and the piston 3 drives the corresponding resin plate 7 to move back and forth through the connecting rod 4, thereby greatly improving the stability of the movement of the resin plate 7.
[0017] As an implementation method in this embodiment, in order to improve the accuracy of the drilling rig and avoid the dust collection unit blocking the drill bit, a return air pipeline 1 and an air intake pipeline 5 connected to the top and bottom ends of the cylinder 2 are provided on the dust collection hood shell 6, wherein the return air pipeline 1 and the air intake pipeline 5 are installed inside the dust collection hood shell 6, and preferably multiple cylinders 2 share one return air pipeline 1 and air intake pipeline 5 to reduce the installation workload. When the air flow enters the air intake pipeline 5, the gas lifts the piston 3, and the piston 3 drives the resin plate 7 to rise through the connecting rod 4, so that the drill bit leaks out, which is convenient for the staff to observe the drilling area. When the gas in the air intake pipeline 5 is discharged, the return air pipeline 1 is connected to the atmospheric pressure, which is convenient for the external gas to flow into the top of the cylinder 2 through the return air pipeline 1, so that the piston 3 can move downward by gravity after the gas is discharged. In order to improve the convenience of air supply, the air source adopts the air compressor provided by the submersible drilling rig, and the air intake pipeline 5 is supplied with air through the self-pressure reducing valve, and the air pressure is set between 5-8bar.
[0018] As an implementation method of this embodiment, a sealing strip 8 is fixedly installed on the end of the resin plate 7 that contacts the ground. The sealing strip 8 is a plurality of soft mesh strips with a height of 10 cm, which ensures that the resin plate 7 is in full contact with the ground and guarantees the sealing of dust collection.
[0019] When in use, the dust collecting switch in the control cabin is turned on to disconnect the electromagnetic valve that controls the air circuit, the piston 3 in the cylinder 2 falls freely, the resin plate 7 contacts the ground, and the sealing strip 8 below can fill the untouched part. When the driver finishes in the control cabin, the electromagnetic valve controls the air circuit to open, the air flow in the air compressor is reduced in pressure by the pressure reducing valve and then introduced into the air intake pipe 5, the gas lifts the piston 3, drives the resin plate 7 to rise, separates from the ground, and the drilling cycle is repeated after the machine is moved.
[0020] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
