The invention discloses an excavator bucket hydraulic cylinder protection device which comprises a small arm. Hydraulic cylinder hinge plates which are symmetrical front and back are fixedly arrangedon the right end face of the upper side of the small arm; a hydraulic cylinder hinge shaft is fixedly arranged between the end faces, close to each other, of the hydraulic cylinder hinge plates on thefront side and the rear side; and a hydraulic cylinder hinge joint extending downwards is in hinge joint to the excircle surface of the hydraulic cylinder hinge shaft. According to the excavator bucket hydraulic cylinder protection device provided by the invention, dustproof protection is carried out on an excavator bucket hydraulic cylinder, so that dust driven by an excavator during work can beeffectively prevented from being attached to a hydraulic telescopic rod, and then the risk that the hydraulic cylinder is abraded quickly due to dust attachment can be reduced, and meanwhile, the hydraulic telescopic rod can be prevented from being damaged by external hard objects such as broken stones; meanwhile, the device can cool the hydraulic cylinder in a high-temperature working environment, so that the risk of the working process is reduced; and meanwhile, the device is further provided with an underwater operation sealing device, so that corrosion of sewage to the hydraulic cylinderis prevented, and the service life of the hydraulic cylinder can be prolonged.
本发明公开的一种挖掘机铲斗液压缸保护装置，包括小臂，所述小臂上侧右端面固定设有前后对称的液压缸铰接板，前后两侧所述液压缸铰接板相互靠近端面之间固定设有液压缸铰接轴，所述液压缸铰接轴外圆面铰链连接有向下延伸的液压缸铰接头，本发明通过对挖掘机铲斗液压缸进行防尘保护，能够有效的避免挖掘机在工作时带动的粉尘附着在液压伸缩杆上，进而能够降低粉尘附着造成液压缸加快磨损的风险，同时能够防止外界碎石等硬物对液压伸缩杆的破坏，同时本装置能够对处于高温工作环境下的液压缸进行降温处理，降低了工作过程的风险，同时本装置还设有水下作业密封装置，防止污水对液压缸的侵蚀，进而能够延长液压缸的使用寿命。
