Abstract
The invention discloses a percussion drill with a noise elimination protective device. The percussion drill comprises a casing, wherein a drill bit fixer is arranged at the front end of the casing; an annular chute is formed in the casing outside the drill bit fixer; a noise elimination sleeve is arranged in the annular chute; an elastic component is connected with the rear end of the noise elimination sleeve; a check block is fixedly connected with the rear end of the elastic component. Due to the mode, the noise caused by the percussion drill can be reduced during the working of the percussion drill, the arranged elastic component enables the noise elimination sleeve and the percussion drill to synchronously stretch out and draw back, not only is the noise reduced, but also the security of an operator can be ensured, the percussion drill is safe and convenient to operate, and the working efficiency is greatly improved.
Description
Technical field
The present invention relates to percussion drill field, particularly relate to a kind of percussion drill with silencer guard.
Background technology
Traditional percussion drill is because power is large, often can bring very large noise in the course of the work, not only constructor operating personnel are brought the impact of health, to other staff, also can bring certain puzzlement, operating personnel operate by holding mode, and very near apart from percussion drill, larger noise not only brings certain influence to operator's health, simultaneously also can make operator produce boredom, lower operating efficiency.And general percussion drill generally can not carry out safe precaution measure to drill bit, if the phenomenon such as occur skidding in early operating process can be brought danger to operating personnel.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of percussion drill with silencer guard, can make middle reduction noise and can improve security protection workmen simultaneously in percussion drill work.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of percussion drill with silencer guard is provided, comprise: housing, described housing front end is provided with drill bit fixator, outside described drill bit fixator, in housing, offer annular groove, in described annular groove, be provided with noise reduction cover, described noise reduction cover end connects a flexible member, and described flexible member rear end is fixedly connected with block.
In a preferred embodiment of the present invention, described flexible member is Compress Spring.
In a preferred embodiment of the present invention, described noise reduction cover is loop pipe column type noise reduction cover, and described noise reduction cover is built in corresponding described annular groove.
In a preferred embodiment of the present invention, described noise reduction cover front end ring port cross section relative level face flushes setting.
In a preferred embodiment of the present invention, described noise reduction cover inner side ring wall is provided with one deck noise reduction bed course.
In a preferred embodiment of the present invention, described noise reduction bed course is made by damping material.
In a preferred embodiment of the present invention, on described noise reduction cover front end annular end face, be also provided with a protection packing ring, described protective pad ring cross-section is also that relative level face flushes setting.
In a preferred embodiment of the present invention, described noise reduction cover length is 8cm-15cm.
The invention has the beneficial effects as follows: the present invention can reduce the noise that percussion drill brings in the percussion drill course of work; the noise reduction cover that is arranged so that by flexible member is followed percussion drill synchronization telescope; not only can reduce noise; can protect operator's safety simultaneously; easy-to-operate, has improved operating efficiency greatly.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation that the present invention has percussion drill one preferred embodiment of silencer guard;
Fig. 2 is the overall schematic that the present invention has percussion drill one preferred embodiment of silencer guard;
In accompanying drawing, the mark of each parts is as follows: 1, housing; 2, drill bit fixator; 3, annular groove; 4, noise reduction cover; 5, flexible member; 6, block; 7, ring port; 8, noise reduction cover inner side ring wall; 9, noise reduction bed course; 10, protection packing ring.
The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of percussion drill with silencer guard, comprise: housing 1, described housing 1 front end is provided with drill bit fixator 2, in described drill bit fixator 2 outside housings, offer annular groove 3, in described annular groove 3, be provided with noise reduction cover 4, described noise reduction is overlapped 4 ends and is connected a flexible member 5, and described flexible member 5 rear ends are fixedly connected with block 6.
In addition, described flexible member 5 is Compress Spring.
In addition, described noise reduction cover 4 is loop pipe column type noise reduction cover, and described noise reduction cover 4 is built in corresponding described annular groove 3.
In addition, described noise reduction is overlapped 4 front end ring port 7 cross section relative level faces and is flushed setting, and arranging of the ring port 7 flushing can make operator's quiet run.
In addition, described noise reduction cover inner side ring wall 8 is provided with one deck noise reduction bed course 9.
In addition, described noise reduction bed course 9 is made by damping material, by this layer of damping bed course, reduces the noise producing in construction.
In addition, described noise reduction is overlapped and on 4 front end annular end faces 7, is also provided with a protection packing ring 10, described protection packing ring 10 cross sections are also that relative level face flushes setting, protection packing ring 10 is for protecting the destruction of noise reduction cover to construction surface, if pad ring 10 in the air, the ring port 7 of noise reduction cover 3 may bring to construction surface the injuries such as impression.
In addition, to overlap 4 length be 8cm-15cm in described noise reduction.
Operation principle of the present invention is for overlapping 4 by an annular noise reduction is set at percussion drill front end; noise reduction cover 4 is controlled by the flexible member 5 that is arranged on its rear end; flexible back and forth in annular groove 3 on being opened in drill bit fixator 2 outside housings; coordinate percussion drill work; on the ring wall 8 of noise reduction cover inner side, be provided with damping noise reduction layer; impact is bored and is played the effect that reduces noise and protection operating personnel; in noise reduction, overlap 4 front end ring port 7 places simultaneously and be provided with protection packing ring 10, while avoiding using, 4 pairs of construction surface of noise reduction cover cause unnecessary destruction.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
