Multifunctional machine and tool hydraulic assistance system of excavator
The invention discloses a multifunctional machine and tool hydraulic assistance system of an excavator. The multifunctional machine and tool hydraulic assistance system comprises a main control valve, an electromagnetic proportional pressure reducing valve set, an electromagnetic reversing valve, a foot valve, a hydraulic control reversing valve, a shuttle valve, an electricity switch, a pressure switch, an electrical switch set, a hydraulic oil tank and a filter. According to the multifunctional machine and tool hydraulic assistance system, on the basis of a one-way special machine and tool hydraulic system, the special machine and tool system with the one-way function and the two-way function at the same time is obtained by adding the hydraulic control reversing valve, the electromagnetic reversing valve, the pressure switch, the electrical switch set, the shuttle valve and the electromagnetic proportional pressure reducing valve set. In practical use, various functions of the excavator can be achieved by only replacing special machines and tools under the condition that hydraulic pipelines are not increased. The actual operation process is simple and reliable, cost is reduced, and the system has important significance in development of the multifunctional machines and tools of the excavator.
