Ultrasonic vibration-type frozen earth digging device
The invention discloses an ultrasonic vibration-type frozen earth digging device. The ultrasonic vibration-type frozen earth digging device comprises bucket teeth. The bucket teeth are movably installed at the front end of a digging bucket. A bucket movable arm and a movable arm oil cylinder are both arranged at the rear end of the digging bucket. One end of the bucket movable arm is connected with the digging bucket in a rotating mode, and the other end of the bucket movable arm is connected with one end of the movable arm oil cylinder in a rotating mode. The other end of the movable arm oilcylinder is connected with the digging bucket in a rotating mode. An ultrasonic vibration transducer is installed inside the bucket teeth and further connected with a power source. According to the ultrasonic vibration-type frozen earth digging device, the ultrasonic vibration transducer is arranged, hydraulic machines and ultrasounds are combined, sufficient vibration power in the cutting direction of frozen earth is guaranteed, and thermal action, mechanical action and cavatition action produced during interaction of ultrasonic waves and media in the transmitting process of the ultrasonic waves can greatly reduce soil digging resistance; when the ultrasonic vibration-type frozen earth digging device is adopted for digging, the soil hot melting level is small, and hot melting collapsing can be avoided; and moreover, ultrasonic vibration and mechanical excavation are conducted at the same time, efficiency is high and construction cost is low.
本发明公开了一种超声振动式冻土挖掘装置，包括铲斗斗齿，铲斗斗齿活动安装在挖掘铲斗的前端，铲斗动臂及动臂油缸均设置在挖掘铲斗的后端，铲斗动臂的一端与挖掘铲斗转动连接，铲斗动臂的另一端与动臂油缸的一端转动连接，动臂油缸的另一端与挖掘铲斗转动连接；超声振动换能器安装在铲斗斗齿中，超声振动换能器与电源连接；本发明通过设置超声振动换能器，将液压机械与超声相结合，确保了在冻土切削方向保持足够大的振动功率，超声波在传播过程中与媒介相互作用会产生的热作用、机械作用、空化作用，可以极大降低土壤挖掘阻力；采用该挖掘装置挖掘时，土壤热融层面小，不会造成热融坍塌，且超声振动与机械挖掘同时进行，效率高，施工成本低。
