Abstract

The utility model provides a novel breaking hammer shell, and belongs to the field of breaking hammers. The utility model solves the problem that when back chipping operation is carried out on some narrow corners, the head of a conventional breaking hammer shell is of a right-angle structure and can interfere with a non-breaking surface, so that the operation effect is influenced. The novel breaking hammer shell comprises a breaking hammer shell body and a hammer core assembly, a lining plate is arranged between the breaking hammer shell body and the hammer core assembly, and a wear-resisting strip of a circular structure is arranged at the front end of the breaking hammer shell body. The back gouging device has the advantage of improving the back gouging effect.

Description

Technical Field

[0001] The utility model belongs to the field of breaker hammers, and relates to a breaker hammer housing, in particular to a novel breaker hammer housing. Background Art

[0002] The breaker hammer has become an important working tool for excavators. As an important component of the breaker hammer, the quality of the housing directly affects the quality of the breaker hammer. The housing of the breaker hammer plays a protective role for the breaker hammer core assembly and connects the hammer body to the excavator. The housing can effectively protect the internal key components such as the hammer body and piston from damage.

[0003] In the case of relatively harsh working environments, the existing breaker hammers need to regularly disassemble and maintain the hammer core assembly frequently. However, the existing housing structure makes it difficult to disassemble the hammer core assembly, which affects the repair and maintenance of the hammer core assembly and increases the use cost of the breaker hammer; when performing root cleaning operations in some narrow corners, due to the right-angle structure of the head of the conventional breaker hammer housing, it will interfere with the non-breaking surface and affect the operation effect. Summary of the Invention

[0004] The purpose of the utility model is to provide a novel breaker hammer housing that is convenient for disassembling the hammer core under the working conditions of narrow corners in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A novel breaker hammer housing includes a breaker hammer housing and a hammer core assembly. A lining plate is arranged between the breaker hammer housing and the hammer core assembly. It is characterized in that a wear-resistant strip with a circular structure is arranged at the front end of the breaker hammer housing.

[0006] In the above-mentioned novel breaker hammer housing, the height of the wear-resistant strip is lower than that of the breaker hammer housing, and the height of the breaker hammer housing is lower than that of the lining plate.

[0007] In the above-mentioned novel breaker hammer housing, the hammer core assembly includes a front cylinder block, and the front cylinder block protrudes or is lower than the wear-resistant strip, and the distance is between 0-50 mm.

[0008] In the above-mentioned novel breaker hammer housing, the wear-resistant strip has an arc structure, and the radius of the wear-resistant strip is greater than 150 mm.

[0009] Compared with the prior art, the novel breaker hammer housing of the present utility model helps the breaker hammer to perform root cleaning operations in narrow corners through the wear-resistant strip with a circular structure, which helps to increase the operation range; when the height of the wear-resistant strip is lower than the height of the breaker hammer housing and the lining plate, it helps to facilitate the removal of the hammer core assembly from the breaker hammer housing for replacement or repair when the internal components of the breaker hammer are damaged, without disassembling the entire housing, greatly improving the repair efficiency and convenience. Description of the Drawings

[0010] Figure 1 is a schematic three-dimensional structure diagram of the housing of the present new breaker hammer.

[0011] Figure 2 is a top view of the housing of the present new breaker hammer.

[0012] Figure 3 is a partial schematic diagram of the housing of the present new breaker hammer.

[0013] In the figure, 1 is the housing of the breaker hammer; 2 is the hammer core assembly; 3 is the lining plate; 4 is the wear-resistant strip; 5 is the front cylinder block. Detailed Description of the Invention

[0014] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0015] As Figure 1 、 Figure 2 、 Figure 3 shown, the housing 1 of the present new breaker hammer includes the housing 1 of the breaker hammer and the hammer core assembly 2. A lining plate 3 is arranged between the housing 1 of the breaker hammer and the hammer core assembly 2. A wear-resistant strip 4 with a circular structure is arranged at the front end of the housing 1 of the breaker hammer. The wear-resistant strip 4 with a circular structure facilitates the root cleaning operation of the breaker hammer and improves the root cleaning effect.

[0016] In further detail, the height of the wear-resistant strip 4 is lower than that of the housing 1 of the breaker hammer, and the height of the housing 1 of the breaker hammer is lower than that of the lining plate 3. The different height differences at different levels facilitate the disassembly and assembly of the hammer core of the breaker hammer and are not easily stuck in the housing 1 of the breaker hammer.

[0017] In further detail, the hammer core assembly 2 includes a front cylinder block 5. The front cylinder block 5 protrudes or is lower than the wear-resistant strip 4, and the distance is between 0 - 50 mm.

[0018] In further detail, the wear-resistant strip 4 has an arc-shaped structure, and the radius of the wear-resistant strip 4 is greater than 150 mm.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0020] Although the terms such as breaker housing 1, hammer core assembly 2, liner 3, wear strip 4, front cylinder block 5, etc. are used more frequently in this text, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present utility model; interpreting them as any kind of additional limitation is contrary to the spirit of the present utility model.
