Description

Technical Field

[0001] The utility model relates to the field of drilling rigs, and in particular to a dust collecting pipeline anti-blocking mechanism for a drilling rig. Background Art

[0002] In mining and engineering construction, a commonly used type of construction machinery is the drilling rig. During the drilling process, the most important thing is dust control. The combined use of the dry and wet dust removal systems of the drilling rig can ensure that dust is effectively controlled during drilling. When using the dust collection system, wet dust reduction is performed first and then dry dust collection is performed. The dust is collected through the dust collection pipeline and then placed at a fixed point. Because the dust in the rock mass is first sprayed by atomization and then collected by the dust collector, the dust has been dampened. When passing through the bends or damaged parts of the dust collection pipeline, it is easy to adhere to the pipe wall. Over time, it will form a relatively hard agglomerate and block the dust collection pipeline, affecting the dust collection effect, and even requiring shutdown and disassembly.

[0003] At present, the dust needs to be collected and processed during the use of the drilling rig, but the following problems still exist in the dust collection process:

[0004] 1. The dust collecting pipe is adhered by damp rock powder, which makes the pipe diameter smaller and affects the dust collecting effect;

[0005] 2. When the dust collection pipe is blocked, it needs to be disassembled and cleaned, which increases the workload of personnel, increases unnecessary maintenance work, and brings safety risks;

[0006] 3. When connecting the existing dust collecting pipe, a clamp is usually used or it is directly tightened for connection, the sealing effect of the connection is not good, and it is very troublesome to connect and disassemble;

[0007] Therefore, we make improvements on this and propose a drilling rig dust collection pipe anti-blocking mechanism. Utility Model Content

[0056] Specifically, the working principle of this solution is:

[0057] When in use, the fan 2 can be started to blow the external cold air into the connecting pipe 401 through the first air duct 3. At the same time, the heat sink 405 on the surface of the mounting plate 404 can conduct heat to the high-temperature air inside the box 1, blow the high temperature into the connecting pipe 401, heat the external cold air blown into the connecting pipe 401, and blow the hot air inside the connecting pipe 401 into the dust collecting hose 6 through the second air duct 5 on the lower side, which can provide heat to the dust collecting pipe, accelerate dust drying, and prevent agglomeration. At the same time, the heat inside the box 1 is absorbed by the heat sink 405, so as to achieve the effect of heat dissipation of the high-temperature components inside the box 1.

[0058] When the dust collecting hose 6 needs to be installed, the connecting ring 703 fixedly installed on the surface of the first connecting head 701 is inserted into the second connecting head 702, so as to facilitate the assembly and connection of the first connecting head 701 and the second connecting head 702. The internal sealing ring 704 can be squeezed by the connecting ring 703 to improve the sealing effect between the first connecting head 701 and the second connecting head 702. Then, the rotating block 710 is twisted by a screwdriver or other tool to drive the screw 709 to rotate in the slider 707, drive the slider 707 to slide in the slide groove 706, and make the lower end of the slider 707 be stuck in the inclined groove 705, fix the connecting ring 703, and achieve the purpose of fixed connection between the first connecting head 701 and the second connecting head 702, thereby achieving the effect of convenient connection between the second air duct 5 and the dust collecting hose 6.
