The invention provides a hydraulic control oil way of a hopper. The hydraulic control oil way comprises an oil inlet pipe, an oil return pipe and a hydraulic cylinder and further comprises a first plug-in throttling valve, a second plug-in throttling valve and a first solenoid valve for switching and controlling the first plug-in throttling valve and the second plug-in throttling valve to be opened. An oil inlet of the first plug-in throttling valve is connected with the oil inlet pipe, and an oil outlet of the second plug-in throttling valve is connected with the oil return pipe. An oil outlet of the first plug-in throttling valve and an oil inlet of the second plug-in throttling valve are both connected with the hydraulic cylinder. The invention further provides a hopper gripper. The hopper gripper comprises the control oil way. According to the hydraulic control oil way of the hopper and the hopper gripper, the first solenoid valve switches and controls the first plug-in throttlingvalve and the second plug-in throttling valve to be opened, the opening and closing action and speed of the hopper gripper can be controlled, the pipeline is simple and reliable, and high popularization and use value and good economical efficiency and universality are achieved.

    本发明提供一种料斗液压控制油路,包括进油管、回油管以及液压缸,还包括第一插装式节流阀、第二插装式节流阀以及用于切换控制所述第一插装式节流阀与所述第二插装式节流阀打开的第一电磁阀,所述第一插装式节流阀的进油口与所述进油管连接,所述第二插装式节流阀的出油口与所述回油管连接,所述第一插装式节流阀的出油口与所述第二插装式节流阀的进油口均连接所述液压缸;还提供一种料斗抓爪,包括上述控制控制油路。本发明中,由第一电磁阀来切换控制第一插装式节流阀与第二插装式节流阀打开,可以实现控制料斗抓爪打开和合拢动作和速度,且管路简洁可靠,有着很好的推广使用价值及良好的经济型和通用性。
