[0001] The utility model belongs to the technical field of dust reduction, and in particular relates to a smoke and dust reduction device for a down-the-hole drill used in water conservancy construction. Background Art

[0002] During the water conservancy construction process, down-the-hole drilling operations will produce a large amount of smoke and dust, which not only pollutes the construction environment, but also causes serious harm to the health of construction workers.

[0003] Patent CN216342116U discloses a dust removal device for a down-the-hole drill, comprising a dust cover and a cylinder sleeved on the outer peripheral surface of the dust cover, a water injection chamber formed between the dust cover and the cylinder, and the water injection chamber is connected to the internal space of the dust cover; during the drilling process, the water injection chamber is filled with water, and the internal space is sprayed with water to remove dust through a position connected to the dust cover. When the dust removal device in the prior art is in use, the dust cover is in contact with the internal dust environment for many years, and dust and small particles will inevitably accumulate in the internal structure and the water injection chamber. If they are not cleaned in time, serious blockage may occur. For this reason, we propose a smoke and dust reduction device for down-the-hole drilling for water conservancy construction.

[0025] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1 - Figure 5 As shown, a smoke and dust reduction device for a down-the-hole drill used in water conservancy construction includes a mounting base 1 and a dust cover 2 provided on the mounting base 1. A cover body 3 is provided in the mounting base 1, and a cavity is formed between the mounting base 1 and the cover body 3.

[0028] Also included are:

[0029] Positioning rods 4, there are multiple positioning rods 4 and they are arranged on the mounting base 1;

[0030] The action mechanism 5 is arranged on one of the positioning rods 4;

[0031] The gear ring 6 is rotatably mounted on the mounting base 1. When the drill rod is working, the gear ring 6 rotates through the cooperation of the positioning rod 4 and the action mechanism 5.

[0032] The brush 7 is arranged on the gear ring 6, and the surface of the cover body 3 is cleaned by the brush 7.

[0033] Positioning rods 4 are arranged in a circular array on mounting base 1. One end of each positioning rod 4 is pivotally mounted with a vertical rod 41. Vertical rod 41 is mounted with a roller 42. Roller 42 contacts the drill pipe, and the down-the-hole drill begins to operate, causing the drill pipe to rotate at high speed. At this point, the positioning rods 4 arranged in a circular array on mounting base 1 come into play. Roller 42, pivotally mounted on vertical rod 41 at one end of each positioning rod 4, tightly contacts the rotating drill pipe, and the friction of the drill pipe drives roller 42 to rotate.

[0034] The action mechanism 5 includes a second vertical rod 51, which is arranged on one of the positioning rods 4. A synchronous wheel 52 is provided on the second vertical rod 51 and the first vertical rod 41, and a synchronous belt 53 is provided between the synchronous wheels 52. A gear 54 is provided on the second vertical rod 51, and the gear 54 is engaged with the ring gear 6. The second vertical rod 51 cooperates with the first vertical rod 41 with the roller 42 thereon. The synchronous wheels 52 provided on the second vertical rod 51 and the first vertical rod 41 are connected by a synchronous belt 53, realizing the synchronous rotation of the two. As the second vertical rod 51 rotates, the gear 54 provided thereon also rotates together, and the gear 54 is engaged with the ring gear 6 set on the mounting seat 1 through the rotating seat 11, thereby driving the ring gear 6 to rotate stably.

[0035] A rotating seat 11 is provided on the mounting seat 1 , and the gear ring 6 is rotatably provided on the mounting seat 1 via the rotating seat 11 . A water inlet pipe 12 is provided on the mounting seat 1 .

[0036] Multiple drainage holes 31 are evenly distributed throughout the housing 3. An external water supply is connected to the water inlet pipe 12 on the mounting base 1. Water enters the cavity formed between the mounting base 1 and the housing 3 through the water inlet pipe 12. Water accumulates within the cavity and then flows out of the drainage holes 31, forming a water curtain on the exterior of the housing 3. Smoke and dust generated by down-the-hole drilling come into contact with the water curtain during their ascent. Dust particles are absorbed by the water and flow down with it, effectively reducing dust. This reduces smoke and dust pollution in the construction area, safeguards the air quality of the construction environment, and protects the health of construction workers, enabling efficient and environmentally friendly down-the-hole drilling operations.

[0037] The brush 7 is in close contact with the surface of the cover body 3. During the rotation of the gear ring 6, the brush 7 continuously cleans the surface of the cover body 3, removes dust, soil and other impurities that may be attached to the surface of the cover body 3 during the dust reduction process, ensures the cleanliness of the cover body 3, and prevents the dust reduction effect from being affected by dirt on the surface of the cover body 3.

[0038] It should be noted that when the down-the-hole drill smoke and dust reduction device for water conservancy construction is in operation, the drill rod rotates, and the roller 42 on the vertical rod 1 41 at one end of the positioning rod 4 arranged in a circular array on the mounting seat 1 contacts the drill rod, and the drill rod drives the roller 42 to rotate. The vertical rod 2 51 set on one of the positioning rods 4 and the vertical rod 1 41 are synchronized through the synchronous wheel 52 and the synchronous belt 53, and the gear 54 on the vertical rod 2 51 rotates accordingly. Since the gear 54 engages with the ring gear 6 set on the mounting seat 1, the ring gear 6 begins to rotate. The brush 7 set on the ring gear 6 is in close contact with the surface of the cover body 3, so that during the rotation of the ring gear 6, the brush 7 cleans the surface of the cover body 3. At the same time, water can enter the cavity formed between the mounting seat 1 and the cover body 3 through the water inlet pipe 12 on the mounting seat 1. The multiple drainage holes 31 evenly opened on the cover body 3 allow water to flow out to form a water curtain, thereby achieving the purpose of dust reduction.

[0039] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
