Novel exhaust structure of front cylinder of breaking hammer

Abstract

The utility model provides a novel exhaust structure of a front cylinder of a breaking hammer, and belongs to the technical field of breaking hammers. The problem that an existing breaking hammer is not high in exhaust efficiency is solved. According to the novel exhaust structure of the front cylinder of the breaking hammer, the breaking hammer comprises a shell, a piston, a drill rod and the front cylinder, a plurality of exhaust holes for exhausting gas are formed in the front cylinder, and outer exhaust holes communicated with the exhaust holes are formed in the shell. The utility model has the advantages that the tapping difficulty is reduced, the exhaust efficiency is improved, the later maintenance is convenient, and the cost is low.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of breaking hammer, and relates to a new exhaust structure of front cylinder of breaking hammer. BACKGROUND

[0002] When the breaking hammer works, the piston reciprocates to impact the drill rod, and with the movement of the piston, stamping gas is formed between the piston and the drill rod. In order to exhaust the gas, a long exhaust hole is currently formed along the front cylinder towards the middle cylinder, and a corresponding exhaust hole is formed at the end of the exhaust hole on the shell of the breaking hammer, but the applicant finds that the exhaust path of the exhaust hole is long, and the exhaust effect is still affected to a certain extent, resulting in the problem of low exhaust efficiency. SUMMARY

[0003] The utility model discloses a kind of new exhaust structures of front cylinder of breaking hammer to solve the above problems, to solve the above problems.

[0004] The utility model discloses a kind of new exhaust structures of front cylinder of breaking hammer, the breaking hammer includes shell, piston, drill rod and front cylinder, characterized in that, the front cylinder is opened with several exhaust holes for gas exhaust, the shell is opened with exhaust outer hole that exhaust hole intercommunicates.

[0005] In the above-mentioned new exhaust structure of front cylinder of breaking hammer, the exhaust hole is opened in the single side or both sides of piston.

[0006] In the above-mentioned new exhaust structure of front cylinder of breaking hammer, the exhaust hole is cylindrical exhaust hole or conical exhaust hole.

[0007] Compared with prior art, the new exhaust structure of front cylinder of breaking hammer has the advantages of reducing opening difficulty, improving exhaust efficiency, facilitating maintenance and low cost. BRIEF DESCRIPTION OF DRAWINGS

[0010] In the drawing, 1, shell;2, drill rod;3, front cylinder;4, exhaust hole;5, exhaust outer hole;6, piston. DETAILED DESCRIPTION

[0011] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with drawings, but the utility model is not limited to these embodiments.

[0012] As Figure 1 ,Figure 2 As shown in the figure, the new exhaust structure of the front cylinder of the breaking hammer comprises a shell 1, a piston 6, a drill rod 2 and a front cylinder 3, a plurality of exhaust holes 4 for exhausting gas are arranged on the front cylinder 3, the exhaust holes 4 are arranged with the advantages of convenient maintenance and low cost, and an exhaust outer hole 5 is arranged on the shell 1 and communicates with the exhaust hole 4, so as to directly exhaust the gas.

[0013] Preferably, the exhaust hole 4 is arranged on one side or both sides of the piston 6.

[0014] Further, the exhaust hole 4 is a cylindrical exhaust hole 4 or a conical exhaust hole 4, or other exhaust holes 4 with other opening shapes.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0016] Although the terms such as shell 1, drill rod 2, front cylinder 3, exhaust hole 4, exhaust outer hole 5, piston 6 are used more frequently herein, but the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present application; any kind of additional limitation is contrary to the spirit of the present application.
