Abstract
The utility model aims at providing a dustproof rock drilling machine so as to protect physical health of constructors. A steel chisel is arranged at the end of the dustproof rock drilling machine, and a hollow channel for communicating a chisel head and a chisel tail is arranged in the steel chisel. The dustproof rock drilling machine is characterized in that a chisel body of the steel chisel is provided with a water-spraying hole communicated with the hollow channel. In the drilling process, pressure water is pressed from the position of the chisel tail to the hollow channel, part of water flow flows out of the position of the chisel head and is used for enabling rock dregs to be discharged out of the hole, another part of water flow is sprayed out of the position of the water-spraying hole arranged on the chisel body so as to adsorb dust diffused at the position of the chisel head, the dust falls to underground along with the water flow, and dust inhalation by the constructors is avoided. By improving structure of the steel chisel of the dustproof rock drilling machine and additionally arranging the dustproof water-spraying hole, the dust diffused at the position of the chisel head can be isolated from the constructors, and extremely good protection effect is achieved.
Description
Technical field
The utility model belongs to plant equipment manufacturing technology field, specially refers to a kind of dustproof hammer drill.
Background technology
Hammer drill is the instrument of direct quarrying stone.Its Drilling on the rock stratum goes out borehole, removes to blow rock in order to put into explosive, thereby completes quarrying stone or other stonework.In addition, hammer drill also can transform destructor into, is used for the solid bed of broken concrete and so on.
Hammer drill carries out work by the impact grinding principle.During work, piston is done the high-frequency reciprocating motion, constantly impacts bit shank.Under the effect of impact force, the bore bit that is the glut shape is crushed rock and digs into certain degree of depth, forms one indenture.After piston was return, hammer drill turned over certain angle, and piston advances forward when again impacting bit shank, forms again new indenture one.Fan-shaped sillar between the twice indenture is shredded by the horizontal component that produces on bore bit.Piston constantly impacts bit shank, and from the centre bore of hammer drill input compressed-air or press water continuously, outside rock slag tap, namely forms the circular bore of certain depth.
When the hammer drill operation, the bore bit place can produce a large amount of dust, gives constructor's the healthy adverse effect of bringing, and even can cause the pneumoconiosis accident.
The utility model content
The purpose of this utility model is to propose a kind of dustproof hammer drill, and is healthy to protect the constructor's.
Dustproof hammer drill of the present utility model, its end is provided with drill rod, and the inside of described drill rod is provided with the hollow channel that is communicated with bore bit and bit shank, and key is that the pricker body of described drill rod is provided with the hole for water spraying that is communicated with described hollow channel.
In boring procedure, be pressed into press water in from bit shank to hollow channel, wherein a part of current flow out from bore bit, be used for outside rock slag tap, another part is from the set hole for water spraying ejection of pricker body, adsorbing powder dust with bore bit place diffusion makes it to drop on the ground with current, avoids the constructor is sucked.
Further, described hole for water spraying has a plurality of, and evenly distributedly can form one like this waterwall on a cross section of pricker body, with dust and constructor's isolation, protects better the constructor.
Further, described hole for water spraying is toward the bore bit direction, and the angle between the axis of hole for water spraying and drill rod is acute angle, when current spray from hole for water spraying, can form the water curtain of a taper like this, and with bore bit place's encirclement, dust-proof effect is better.
Dustproof hammer drill of the present utility model has been set up the hole for water spraying that can prevent dust by improving the structure of its drill rod, can be enough that dust and the constructor of bore bit place diffusion is isolated, have good protection effect.
Description of drawings
Fig. 1 is the structural representation of the drill rod of dustproof hammer drill of the present utility model;
Fig. 2 is the partial schematic diagram of the drill rod of dustproof hammer drill of the present utility model.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, each several part and annexation, each several part and operating principle etc. are described in further detail.
Embodiment 1:
The dustproof hammer drill of the present embodiment, its end is provided with drill rod 1, and the inside of drill rod 1 is provided with the hollow channel 4 that is communicated with bore bit 2 and bit shank 3, and the pricker body of drill rod 1 is provided with the hole for water spraying 5 that is communicated with described hollow channel 4; Hole for water spraying 5 has a plurality of, and evenly distributed on a cross section of pricker body, and hole for water spraying 5 is toward bore bit 2 directions, and the angle α between the axis of hole for water spraying 5 and drill rod 1 is acute angle.
In boring procedure, be pressed into press water from bit shank 3 to hollow channel in 4, wherein a part of current flow out from bore bit 2, be used for the rock slag is discharged outside the hole of boring, another part forms the water curtain of a taper from 5 ejections of the set hole for water spraying of pricker body, and the dust of bore bit place diffusion is surrounded and adsorbs, make it to drop on the ground with current, avoid the constructor is sucked.
Claims (3)
