Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, the wet dust collecting device for a down-the-hole drill provided by the present invention comprises a dust hood 1, wherein an opening is formed at the front end of the dust hood 1 and corresponds to a dust collecting end; more importantly, the inner wall of the dust hood 1 is also provided with a spray pipe 2, the spray direction of the spray pipe 2 corresponds to the dust collecting end, the dust hood 1 is also provided with a dust exhaust pipe 3, the dust exhaust pipe 3 is used for communicating the inside and the outside of the dust hood 1, and meanwhile, the dust exhaust pipe 3 is used for communicating with an external dust bag, namely, after the dust in the spray pipe 2 is mixed with dust, the dust can enter the external dust bag through the dust exhaust pipe 3 for storage, so that the dust raising is avoided.

Meanwhile, in the embodiment, the spray pipe 2 is arranged in the dust hood 1, and the spray pipe 2 sprays water to make dust wet and then fall into the dust hood 1, so that the dust can be prevented from leaking out under the action of the air compressor to generate raised dust, the personal health of construction workers and the adverse effect on the surrounding air environment are avoided, and the construction requirements of safety and civilization are met.

As shown in fig. 1, according to another embodiment of the present invention, in order to make the nozzle 2 spray water more uniformly inside the dust cage 1, the nozzle 2 may be designed in a ring shape, and then a plurality of spray holes are formed at an upper portion thereof, and the nozzle 2 is used to communicate with a pressure water pump 5 through a water inlet pipe 4; correspondingly, in the embodiment, in order to ensure the sealing performance of the dust collection cover 1 at the opening and sleeved on the drill rod 11, sealing rings 6 may be further disposed on the inner walls of the front end and the rear end of the dust collection cover 1, and the sealing rings may be made of flexible materials such as silicon rubber and rubber; as shown in fig. 1, the inventor considers the general structure of the processing hole, the dust-collecting cover 1 can be designed into the trumpet shape shown in fig. 1, the trumpet-shaped dust-collecting cover 1 is formed by rolling an arc-shaped material, a hinge is arranged at the annular connection position of the side wall of the dust-collecting cover 1, a closing bolt 7 is arranged on the hinge, the dust-collecting cover 1 is fixed into a trumpet-shaped cylinder shape through the sealing bolt 7, the radial size of the dust-collecting cover 1 can be adjusted through the hinge and the bolt 7, and a sealing strip 8 can be arranged at the connection position of the side wall of the dust-collecting cover 1 to ensure the sealing performance of the side wall of the dust-collecting cover 1.

Further, in order to facilitate the installation of the dust cage 1 on the drill rod 11, a drill rod fixing ring 9 may be installed inside thereof, and the drill rod fixing ring 9 is interposed between the front and rear ends of the dust cage 1. So that the dust cage 1 can be fixed on the drill rod 11 through the drill rod fixing ring 9, namely, the installation as shown in figure 1; meanwhile, in order to facilitate auxiliary fixation, an external fixing rod 10 can be further installed on the outer wall of the dust collection cover 1.

Referring to fig. 1, in practical use, when a down-the-hole drill is required to be used for construction, the wet dust collecting device using the above embodiment has two installation methods, one is to directly install the dust collecting cover 1 at the mouth of a construction hole, the other is to install the dust collecting cover 1 on the drill rod 11 as shown in fig. 1, and in any installation method, a closed space can be formed at the hole opening and around the drill rod 11 by using the sealing rings at the front end and the rear end of the dust collecting cover 1, when the drill rod 11 drives the drill bit 12 to be constructed in the down-the-hole, the generated dust is concentrated in the closed space of the dust collecting cover 11, the pressure water pump 5 sprays water in the closed space through the annular spray pipe 2 via the water inlet pipe 4, the dust in the closed space is moistened and settled in the dust collecting cover 1, and is discharged into an external dust collecting bag via the dust pipe 3 at the lower part of the dust collecting cover 1, therefore, dust is collected through the dust collecting bag, and the problems that raised dust is generated in the construction process, environmental pollution is caused, and the personal health of constructors is influenced are avoided.
