Special hydraulic breaking device for pavement breaking

Abstract

The invention relates to a special hydraulic breaking device for pavement breaking. The special hydraulic breaking device for pavement breaking comprises an operating plate, a convex-shaped support, three hydraulic cylinders, a working plate, four limit springs, three fixed seats and three hammer heads. The two ends of the convex-shaped support are installed at the two sides of the lower end face of the operating plate through bolts. The bottom ends of the three hydraulic cylinders are installed at the lower end face of the operating plate respectively. The top ends of the three hydraulic cylinders are connected with the working plate. The four limit springs are installed between the convex-shaped support and the working plate uniformly. The three fixed seats are welded to the lower end face of the working plate uniformly. Each hammer head comprises a connecting shaft and a head portion. External threads are installed at the upper ends of the connecting shafts. The connecting shafts are connected with the fixed seats. The head portions are welded to the lower ends of the connecting shafts. Six petal-shaped hammer thorns are arranged at the peripheries of the head portions, and character-one-shaped hammer blocks are arranged at the bottom ends of the head portions. According to the special hydraulic breaking device for pavement breaking, the function of quickly breaking small-grained cement blocks on a pavement is achieved, and the advantages of being high in breaking speed, small in breaking grain, small in labor intensity and high in working efficiency are possessed.

Description

technical field [0001] The invention relates to excavator equipment, in particular to a special hydraulic breaking device for road surface breaking. Background technique [0002] The bucket is the embodiment of the ability and efficiency of engineering excavation. The initial manufacturing material of the bucket is ordinary steel. With the continuous expansion of the application range of excavators and bulldozers, the structural design of the bucket is constantly updated, which promotes the selection of bucket materials. It has also developed accordingly; buckets are divided into backhoe buckets and front shovel buckets according to their working methods, and backhoe buckets are generally used. [0003] In the process of building or renovating roads, it is usually necessary to use the hydraulic breaker on the excavator to break the waste road one by one. After the break, replace the hydraulic breaker with a hydraulic bucket, and use the hydraulic bucket to excavate the broke...

AI Technical Summary

Problems solved by technology

[0003] In the process of building or renovating roads, it is usually necessary to use the hydraulic breaker on the excavator to break the waste road one by one. After the break, replace the hydraulic breaker with a hydraulic bucket, and use the hydraulic bucket to excavate the broken road. However, it is difficult for existing hydraulic crushing equipment to quickly crush small-grained cement blocks, and most of the crushed cement blocks are large-grained cement blocks, which have a fatal impact on the excavation speed after crushing. The equipment has defects such as slow crushing speed, large crushed particles, high labor intensity and low work efficiency.
