Abstract
The utility model discloses a dust collection device for dry drilling. A sponge sleeve is arranged on the outer surface of the front end of a main body sleeve. A dust chamber is formed at a front end in the main body sleeve. A dust exhaust hole is formed in the sidewall of the dust chamber, and is connected with a dust exhaust hose. A bearing chamber is formed on the lower part of the dust chamber in the main body sleeve. A bearing is arranged in the bearing chamber. A guide friction sleeve is inserted into the main body sleeve. A dust exhaust wheel is arranged at one end of the dust chamber on the head part of the guide friction sleeve. Three screw holes are uniformly and radially formed in the tail end of the guide friction sleeve. A steel ball, a spring and a pressing plug are arranged in each screw hole. A skeleton seal is arranged between the bearing chamber and the guide friction sleeve. The dust collection device has a simple structure, a dust collection rate of 100 percent and dust sealing, collection and exhaust functions, and is convenient to use, safe, reliable, remarkable in emission reduction effect and applicable to various roof bolt drillers; and dust-free dry drilling is really realized.
Description
Technical field
The utility model relates to a kind of dust arrester that is used for the mine drilling operation.
Background technology
" safety regulations in coal mine " the 17, the 154 regulation for can not adopt wet boring the time, can be taked dry drilling, but must take to catch the dirt measurements for reduction.So far, also there is not a kind of simple and practical dust arrester to solve the dust problem that dry type mine dry type is drilled and produced.Although also can search the design of some patents on the net, even its described result of use is arranged, because package unit is too loaded down with trivial details, the dedusting ratio workload of drilling is also big, is difficult to promote the use of.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, it is a kind of simple in structure, easy to use that the utility model provides, the dry type of the good dedusting effect dust arrester of drilling.
The goal of the invention of the utility model realizes through following technical proposals: the dry type dust arrester of drilling, and it is characterized in that: at main body barrel forward end external surface sponges cover is housed, main body sleeve inner front end is provided with dust storage chamber; The dust storage chamber sidewall is shaped on dust exhausting hole; Dust exhausting hole is connected with the dust discharge flexible pipe, and the bottom of dust storage chamber is provided with bearing chamber in the main body sleeve, and bearing is installed in the bearing chamber; The guiding friction sleeve is inserted in the main body sleeve; At the head of guiding friction sleeve, be positioned at dust storage chamber one end the dust discharge wheel is housed, three screwed holes of guiding friction sleeve tail end radial equipartition; Steel ball, spring are housed in screwed hole, compress plug, be provided with reinforced seal between bearing chamber and the guiding friction sleeve.
Guiding friction sleeve tail end is equipped with seal gasket, and compresses with sealing clamp.
The beneficial effect of the utility model: the utility model adopts said structure, during use, drilling rod is penetrated from the guiding friction sleeve, makes the slightly outstanding sponges cover of drill bit, and sponges cover soaks and gets final product to dampness.When the drilling rod axial advance, guiding compresses stiction band that the steel ball of drilling rod produces on the friction sleeve and whole dust arrester and together be advanced into the aperture crag, and sponges cover is compressed the aperture of shutoff simultaneously periphery and dust storage chamber formation enclosure space gradually.Continue to advance drilling rod; The crag resistance that dust arrester receives increases, and makes to produce between guiding friction sleeve and the drilling rod to slide, and drilling rod overcomes force of sliding friction and creeps into to depth; Constant force of sliding friction makes dust arrester be close to the aperture, and the assurance dust granules does not leak and falls in the dust storage chamber.Stir dust granules when dust discharge wheel and drilling rod rotate synchronously in the dust storage chamber, the low-pressure air that is returned out by boring imports dust granules in the control of dust tube that is filled with water through dust exhausting hole and dust flue.The utility model is simple in structure, and is easy to use, safe and reliable, and emission reduction effect is obvious, and dust removing rate reaches 100%, gives security for creating good climatic environment.In light weight, gross weight＜0.7kg; When the dry type drilling operation, be assemblied on the drilling rod, be applicable to various jumbolters.Have envelope dirt, control of dust and dust discharge function.Realized that really dried punching do not have dust.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The dry type dust arrester of drilling is equipped with sponges cover 1 at main body sleeve 15 front end external surfaces, and main body sleeve 15 interior forward end are provided with dust storage chamber 2; Dust storage chamber 2 sidewalls are shaped on dust exhausting hole 3, and dust exhausting hole 3 is connected with the dust discharge flexible pipe, and the bottom of dust storage chamber 3 is provided with bearing chamber 4 in the main body sleeve 15; Bearing 6 is installed in the bearing chamber 4, and guiding friction sleeve 7 is inserted in the main body sleeve 15, at the head of guiding friction sleeve 7; Be positioned at dust storage chamber 2 one ends dust discharge wheel 14 is housed; Three screwed holes of guiding friction sleeve 7 tail end radial equipartitions are equipped with steel ball 10, spring 9, compress plug 8 in screwed hole, be provided with reinforced seal 5 between bearing chamber 4 and the guiding friction sleeve 7.Guiding friction sleeve 7 tail ends are equipped with seal gasket 11, and sealing clamp 12 compresses through screw 13 with seal gasket 11.
Trial effect: when not using any dust arrester to do punching, be 38.6mg/m apart from 3 meters Dust Capacities of punching
3Apart from 5 meters Dust Capacities of punching is 32.9mg/m
3Apart from 10 meters Dust Capacities of punching is 19.8mg/m
3
Use the utility model dust arrester, no dust, dust removing rate reaches 100%.
Application notice: 1, the sponges cover immersion is an amount of, too much can make dust become mud, is difficult for effluxing.2, it is suitable to compress the thrust of plug, and dust arrester stands fast when vibrating with drilling rod, the drilling rod adapter sleeve can be smoothly through being advisable.3, the dust arrester bottom can not receive roof pressure.4, in time clear up and fail the block coal petrography of discharging in the dust storage chamber.
Claims (2)
