Description

Technical Field

[0001] This invention relates to the technical field of auxiliary mechanisms for hydraulic breakers, specifically to a hydraulic breaker with a structure for preventing splashing and reducing dust. Background Technology

[0002] A hydraulic breaker, also known as a breaker or a hammer, is one of the frequently used accessories for excavators. It is commonly used for tasks such as mountain clearing, road surface breaking, house demolition, bridge demolition, and rock breaking in mines. A Chinese patent document with publication number CN221072803U discloses a dust-reducing and splash-proof structure for a hydraulic breaker. The structure includes a hydraulic breaker body with a protective cover at its bottom end and a connecting assembly at its top. The connecting assembly includes a first pull plate, two sets of first pull plates fixedly connected to one end of a first slider, one set of first sliders fixedly connected to one end of a first spring, the other ends of two sets of first springs fixedly connected to one end of a spring connecting plate, the other ends of two sets of spring connecting plates fixedly connected to one end of a second spring, the other ends of two sets of second springs fixedly connected to another set of first sliders, and a disassembly assembly at the top of the protective cover. However, the above-mentioned solution achieves protection through a protective cover. But since the breaker is not a flat surface when it is actually working, the integrated protective cover will create a large gap between the cover and the ground, which will limit the overall protective effect of the cover. Therefore, this invention proposes a breaker with an anti-splash and dust reduction structure to solve the above problems. Summary of the Invention

[0019] The anti-splash dust suppression structure 3 includes an upper mounting frame 5, a telescopic dust cover 6, a lower mounting frame 7, a fixed dust cover 8, and a dust curtain 9. The upper mounting frame 5 is fixed on the connecting seat 4. The upper end of the telescopic dust cover 6 is fixedly connected to the lower end face of the upper mounting frame 5. The lower mounting frame 7 is fixedly connected to the lower end of the telescopic dust cover 6. The fixed dust cover 8 and the dust curtain 9 are both fixed on the lower mounting frame 7.

[0020] The telescopic dust cover 6 has a corrugated pipe structure, the fixed dust cover 8 has a trumpet-shaped bucket structure, and the dust curtain 9 has a cotton thread structure. The dust curtain 9 is installed on the outer side of the fixed dust cover 8, and the length of the dust curtain 9 is greater than the length of the fixed dust cover 8. By setting up a breaker hammer with a dust-prevention structure, which is composed of the breaker hammer host 1, the breaker head 2, and the dust-prevention structure 3, and setting the dust-prevention structure 3 to be composed of the upper mounting frame 5, the telescopic dust cover 6, the lower mounting frame 7, the fixed dust cover 8, and the dust curtain 9, the dust prevention effect of the dust-prevention structure 3 is effectively improved through the combined action of the telescopic dust cover 6, the fixed dust cover 8, and the dust curtain 9, thereby effectively avoiding dust pollution and preventing the flying of gravel and leaving safety hazards.

[0021] The upper end face is fixedly welded with a screw 10, and the connecting seat 4 is provided with a mounting hole. The mounting hole is set correspondingly to the screw 10. The screw 10 is fixed to the connecting seat 4 by a positioning nut 11, which facilitates the overall replacement and maintenance of the anti-splash dust reduction structure 3.

[0022] In Example 2, based on Example 1, a primary guide plate 15 is integrally formed on the telescopic dust cover 6 at the position of the outer corrugation, and a secondary guide plate 16 is integrally formed on the outer wall of the upper mounting frame 5.
