Technical Field
[0001] This utility model relates to the field of crushing equipment technology, and in particular to an intelligently controlled electro-hydraulic breaker. Background Technology
[0002] In building demolition, traditional methods often generate significant noise and waste, severely impacting the surrounding environment. With increasingly scarce urban land resources, demolition work requires more efficient and precise equipment to minimize disruption to nearby residents. Therefore, the emergence of demolition equipment can effectively improve demolition efficiency while reducing noise and dust emissions, meeting the environmental protection requirements of modern urban construction.
[0003] However, traditional crushing equipment often suffers from high energy consumption, low efficiency, and cumbersome control; therefore, we propose an intelligently controlled electro-hydraulic breaker to solve this problem. Utility Model Content

[0014] In this utility model, an intelligently controlled electro-hydraulic breaker is opened via a nitrogen storage tank.

[0016] This utility model has a reasonable structural design. Through intelligent control, it can achieve more efficient operation and precise control, improve the safety and efficiency of the operation. Combining the dual effects of nitrogen and hydraulic oil, it can optimize power output under different operating conditions and is suitable for various scenarios such as mining and building demolition.
