Problems solved by technology
[0002] When a traditional excavator is used with a breaker, the breaker also needs to operate the downward action of the breaker while striking. At this time, the flow of the pump must not only provide the work of the breaker but also the downward action of the working arm, resulting in The working flow of the breaking hammer is unstable, which affects the working efficiency of the breaking hammer
Moreover, when a traditional excavator is used with a breaker, it is necessary to fill the breaker with butter every two hours to reduce the wear of the drill rod and the precursor of the breaker. The short filling interval is cumbersome and reduces work efficiency.

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] refer to figure 1 The hydraulic mountain driving machine shown includes a breaker 71, a working forearm 83, a working boom 84, a driver's cab 8, an upper car rotating platform 81, a lower car body 82, a flow compensation system and a self-lubricating system.
[0027] refer to figure 2 The flow compensation system shown includes forearm oil cylinder 341, arm oil cylinder 331 and the hydraulic system of the hydraulic mountain digging machine. The forearm oil cylinder 341 controls the movement of the working arm 83, and the arm oil cylinder 331 controls the movement of the working arm 84. Hydraulic mountain machine hydraulic system includes main pump 1, auxiliary pump 2, main multi-way valve 3, auxiliary multi-way valve 4, large and small arm pilot valve 5, pilot switching valve 6, breaker hammer pilot valve 7, of which the large and small arm pilot val...

The invention discloses a hydraulic mountain driving machine, which comprises a breaking hammer, a working arm, a working arm, a driver's cab, an upper car rotating platform, an lower car body, a flow compensation system and a self-lubricating system. The flow compensation system includes a small arm oil cylinder, a large arm oil cylinder and a hydraulic system of a hydraulic mountain machine. The small arm oil cylinder controls the movement of the working forearm, and the large arm oil cylinder controls the movement of the working large arm. The self-lubricating system is connected to the breaker, including a compressor, a gas-water separator, and an oil mist generator connected in sequence through a pressure-resistant hose, and the outlet of the oil mist generator is connected to the lubricating oil of the breaker. import connection. The invention realizes that the flow rate of the breaker is not affected by the action of the big and small arms when the breaker is working, ensures the stable flow rate of the breaker input, improves the use efficiency of the breaker, and at the same time avoids the work of frequently filling the breaker with butter, and improves the equipment. Higher work efficiency, better protection for the breaker.
Description
technical field [0001] The invention relates to the technical field of excavators, in particular to a hydraulic mountain excavator. Background technique [0002] When a traditional excavator is used with a breaker, the breaker also needs to operate the downward action of the breaker while striking. At this time, the flow of the pump must not only provide the work of the breaker but also the downward action of the working arm, resulting in The working flow of the breaking hammer is unstable, which affects the working efficiency of the breaking hammer. Moreover, when a traditional excavator is used with a breaker, it is necessary to fill the breaker with butter every two hours to reduce the wear of the drill rod and the precursor of the breaker. The short filling interval is cumbersome and reduces work efficiency. . Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a hydraulic mountain opener, whi...
