Background

An excavator is a common engineering machine on a construction site, and has the main functions of excavating materials higher or lower than a bearing surface by using a bucket, and loading the materials into a transport vehicle or unloading the materials to an earthmoving machine of a storage yard. In addition to buckets, excavators also have other attachments such as woodgrabers, hydraulic shears, breaking hammers, and the like. By installing different accessories, the excavator can complete various different work contents. The breaking hammer is also called rock clack, and its working principle is that it uses hydrostatic pressure as power to drive piston to make reciprocating motion to impact drill rod, and uses drill rod to break up ore and concrete. The breaking hammer is mainly suitable for breaking old cement pavement, repairing expressway, excavating foundation and the like.

The breaking hammer has the characteristics of simple structure, less faults, convenient maintenance, low cost, large impact energy and the like, but noise, dust, splashed stones and the like generated by the operation of the breaking hammer are also frequently polluted. The residents around the construction site report the noise generated by the breaking hammer, so that people cannot concentrate attention, and the continuous rhythmic sound of 'pan, pan and pan' causes the people to feel listless. Meanwhile, the broken hammer works to generate even splashed small stones, so that pedestrians are easily scratched or surrounding construction operators are easily injured. In real life, the accident that the breaking hammer hurts people is also reported, and adverse effects are brought to management of construction units and urban authorities.

In addition, the current construction unit has fewer measures and methods for controlling the problems of noise, stone splashing, dust emission and the like in a source or propagation way mode, and the actual effect is poor because the actual operation is not performed in place.

Under the circumstances, the breaking hammer civilized construction device which is reasonable in design, simple in structure and wide in applicability is objectively needed to be developed, and adverse effects on the surrounding environment can be reduced while basic functions of the breaking hammer are met, and the breaking hammer civilized construction device has the functions of absorbing noise, reducing flying dust, isolating splashed stones and the like, improves civilized degree of a construction site, and reduces adverse effects on surrounding residential areas so as to build harmonious and attractive construction ecological environment.
