Working principle: The end cover 4 isolates the piston chamber 6 from the piston 5, the oil inlet 7, and the oil return 8 to form a hydraulic cylinder. The high-pressure oil enters through the oil inlet 7 to push the piston 5 to move, and the piston 5 converts hydraulic energy into thrust. The piston, 10 transmits it to the amplitude amplifier 3, and the amplitude amplifier 3 converts the mechanical energy into a mechanical wave through the amplitude amplifier 3, and provides it to the bucket tooth 1, and the bucket tooth 1 generates kinetic energy to vibrate and generate impact force. During excavation, the shovel teeth are forced to vibrate at a certain frequency and intensity to loosen the block materials and reduce the static friction between the blocks, thereby improving the excavation efficiency and output. Hydraulic pressure is used as the power to force the bucket teeth to vibrate at a certain frequency to generate kinetic energy, which destroys the static friction between the blocks and reduces the excavation resistance.

Embodiment 2: The amplitude amplifier is composed of a fixed tooth 2, a wave propagator 3a, a kinetic energy block 3b, a bucket body 9, and a piston rod 10. The wave propagator 3a passes through the inner hole of the fixed tooth 2, and one end is connected to the bucket tooth 1, and the other end is connected to the kinetic energy block 3b, and the kinetic energy block 3b is dynamically matched with the piston chamber, and the other end is connected to the piston rod.

Working principle: After the kinetic energy block 3b receives the energy of the piston rod 10, it generates mass kinetic energy, and then releases it to the wave transmitter 3a to generate mechanical waves for the bucket tooth 1. Others are the same as in Example 1.
