The invention will be further explained with reference to the drawings and examples, wherein:
FIG. 1 is a schematic front sectional view of the down-the-hole drill dust settling device of the present invention;
fig. 2 is the utility model discloses down-the-hole bores dust device's plan view.
Detailed Description
Fig. 1 to 2 show a preferred embodiment of the down-the-hole drill dust-settling device of the present invention, which comprises a support frame 1, a dust-blocking system 2 and a spraying system 3; the supporting frame 1 comprises a ground pressing plate 11, a bracket 12 and a guide cylinder 13, wherein the bracket 12 and the guide cylinder 13 are fixed on the ground pressing plate 11, the ground pressing plate 11 is used for being tightly attached to the ground and used as a base for fixing the bracket 12 and the guide cylinder 13, and in practical application, weights such as sand bags and the like can be piled on the periphery of the ground pressing plate 11 to eliminate the impact force of compressed air on a dust blocking system. The bracket 12 is used for supporting the dust blocking system 2 and the spraying system 3 and is composed of a plurality of columnar rod bodies. The guide cylinder 13 is a hollow cylinder, the outer wall of the guide cylinder is tightly attached to the support 12, and a drill rod of the down-the-hole drill penetrates through the middle of the guide cylinder 13 and has the function of limiting the flowing direction of compressed air with dust and rock-soil particles so as to be blown out from the lower part of the dust blocking system in a centralized manner. The dust blocking system 2 comprises a dust blocking umbrella 21 positioned at the upper part of the guide cylinder 13 and used for restricting the diffusion direction of the air flow and enabling the air flow with dust and particles to diffuse towards the periphery below the dust blocking umbrella. The umbrella surface of the dust-blocking umbrella 21 is parabolic, so that dust and particles in air flow collide with the umbrella surface, partial kinetic energy of the dust-blocking umbrella is attenuated, and larger particle components can sink to the ground after deceleration. The spraying system 3 comprises a high-pressure water pump, a water feeding pipeline 31, a high-pressure water inlet 32, a shunt pipe 33 and a plurality of nozzles, the nozzles are uniformly distributed around the dust-blocking umbrella 21, the high-pressure water pump pumps water from the outside and sends the water into the shunt pipe 33 through the water feeding pipeline 31 and the high-pressure water inlet 32, the water is sprayed out from the nozzles, small un-settled dust and particles form water-solid granules when meeting water, and the granules fall on the ground along with the increase of the granule diameter and weight of the granules, so that the aims of reducing the dust amount and controlling the diffusion range in the drilling process of the down-the-hole drill are.
In this embodiment, the plurality of brackets 12 are uniformly distributed on the lower portion of the dust-blocking umbrella 21 with the center of the draft tube 13 as the center of the circle, and in this embodiment, the plurality of brackets 12 are distributed in four directions of the dust-blocking umbrella 21 and are uniformly stressed. The bracket 12 and the guide cylinder 13 are both vertically welded on the ground-contacting press plate 11, but other fixing methods can be adopted.
The dust blocking system 2 in this embodiment further includes a dust blocking baffle 22, and the dust blocking umbrella 21 includes a first dust blocking umbrella 10 and a second dust blocking umbrella 20 respectively located at two sides; the dust-catching baffles 22 extend from the inner sides of the first dust umbrella 10 and the second dust umbrella 20, respectively, and contact and shield each other at the center of the guide cylinder 13. The dust-catching baffle 22 is an elastic rubber blade, normally in a mutually shielding state, and is located right above the guide shell 13, and the central part of the dust-catching baffle can be inserted through a drill rod with an impactor or other drilling tools. After the impactor or other drilling tools pass through the dust-stopping baffle 22, the elastic dust-stopping baffle 22 is restored to the interactive shielding state, so that wind current, dust and particles cannot pass through the middle dust-stopping baffle 22 and move towards the dust-stopping umbrella 21.
Use the utility model discloses a down-the-hole bores dust device blocks the dust that blows off from the drilling through set up dust umbrella and atomizer outside the drilling, and the diffusion direction of air current can be restrainted to the dust umbrella, reduces the partial kinetic energy of dust, makes partly earlier subsides to ground in the dust, and remaining and water smoke formation great granule descend to ground, effectively reduces the rig and creeps into the volume and the control diffusion scope of in-process dust, reduces environmental pollution.
The above description is only a preferred embodiment of the present invention, and many changes can be made in the detailed description and the application scope according to the idea of the present invention for those skilled in the art, which all belong to the protection scope of the present invention as long as the changes do not depart from the concept of the present invention.
