Abstract
The utility model aims at providing a rock drill facilitating discharge of rock debris to ensure normal drilling operation. The end portion of the rock drill facilitating the discharge of the rock debris is provided with a steel chisel, and a channel used for passing of air or water is arranged in the steel chisel. The rock drill facilitating the discharge of the rock debris is characterized in that the surface of the steel chisel is provided with a groove which extends from the head of the steel chisel to the tail of the steel chisel. In the process of drilling, compressed air or pressure water is continuously injected through the channel in the steel chisel to enable the rock debris at the head of the steel chisel to be discharged outward along with the water or the air. Due to the fact that the groove enlarges the area of the channel for outward discharge, the discharge of the rock debris is facilitated. By means of improvements of the structure of the steel chisel, the rock drill facilitating the discharge of the rock debris enlarges the area of the channel for the discharge of the rock debris, enhances power for the discharge of the rock debris, facilitates the discharge of the rock debris, and has good practicability.
Description
Technical field
The utility model belongs to plant equipment manufacturing technology field, specially refers to a kind of hammer drill of discharging landwaste that is beneficial to.
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 finishes 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.Piston is done the high-frequency reciprocating motion during work, constantly impacts bit shank.Under the effect of impact force, the bore bit that is the glut shape is with the rock crushing and dig into certain degree of depth, forms indenture one.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 the bore bit.Piston constantly impacts bit shank, and from the centre bore of hammer drill continuously input compressed-air or press water, outside rock slag tap, namely forms the circular bore of certain depth.But above-mentioned hammer drill is only discharged the rock slag by the gap between drill rod and the boring, and is therefore smooth and easy not, sometimes even can affect normal boring work.
The utility model content
The purpose of this utility model is to propose a kind of hammer drill of discharging landwaste that is beneficial to, to guarantee the work of holing normally.
The hammer drill of discharging landwaste that is beneficial to of the present utility model, its end is provided with drill rod, and the inside of drill rod is provided with the passage for ventilation or water flowing, and key is that the surface of described drill rod is provided with the groove that is extended to the drill rod bit shank by the drill rod bore bit.
In boring, from the passage of drill rod inside continuously input compressed-air or press water, make the rock slag at bore bit place along with water or air discharge, because groove has enlarged the area that discharges passage, therefore be conducive to discharge landwaste.
Further, described groove is spirality, and the direction of rotation was identical when the direction of rotation of groove was worked with drill rod.Because in the process of boring, drill rod can constantly rotate, and landwaste will be forced in the groove of spiral like this, and constantly is pushed to the drill rod bit shank in follow-up drill rod rotation process, for the discharge of landwaste provides extra power, improved the discharge effect.
Hammer drill of the present utility model has enlarged the area of landwaste passing away by improving the structure of its drill rod, and has strengthened the power that landwaste is discharged, and makes things convenient for landwaste to discharge, and has good practicality.
Description of drawings
Fig. 1 is the elevation of the drill rod of 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, the each several part and annexation, each several part and operating principle etc. are described in further detail.
Embodiment 1:
The hammer drill that is beneficial to the discharge landwaste of the present embodiment, its end is provided with drill rod 1, and the inside of drill rod 1 is provided with the passage 2 for ventilation or water flowing, and key is that the surface of described drill rod 1 is provided with the groove 3 that is extended to the drill rod bit shank by the drill rod bore bit.
In boring, from the passage 2 of drill rod inside continuously input compressed-air or press water, make the rock slag at bore bit place along with water or air discharge, because groove 3 has enlarged the area that discharges passage, therefore be conducive to discharge landwaste.
Further, groove 3 is spirality, and the direction of rotation was identical when the direction of rotation of groove 3 was worked with drill rod 1.Because in the process of boring, drill rod 1 can constantly rotate, and landwaste will be forced in the groove 3 of spiral like this, and constantly is pushed to the drill rod bit shank in the rotation process of follow-up drill rod 1, for the discharge of landwaste provides extra power, improved the discharge effect.
Claims (2)
1. one kind is beneficial to the hammer drill of discharging landwaste, and its end is provided with drill rod, and the inside of drill rod is provided with the passage for ventilation or water flowing, it is characterized in that the surface of described drill rod is provided with the groove that is extended to the drill rod bit shank by the drill rod bore bit.
2. the hammer drill of discharging landwaste that is beneficial to according to claim 1 is characterized in that described groove is spirality, and the direction of rotation was identical when the direction of rotation of groove was worked with drill rod.
