The invention provides a potato digging and harvesting device, which includes a frame, a gearbox arranged on the frame, and a digging shovel for digging potatoes. A connecting frame is connected to the digging shovel; a power output shaft of the gearbox is connected to a The eccentric wheel that moves eccentrically under the action of power, the part that deviates from the center of the eccentric wheel is connected with the connecting frame through the connecting screw. When the eccentric wheel moves eccentrically, it drives the excavating shovel to make a circular motion to loosen the soil to be excavated; the excavating shovel includes a shovel body , The shovel body is provided with a plurality of openings at intervals, forming a grid shape, so as to reduce the force-bearing area of ​​the shovel body. The device reduces the force-bearing area of ​​the shovel body by setting the grid-shaped shovel body, improves the soil penetration ability of the shovel body, and improves work efficiency.

The invention discloses an exciting vibration-aided milling method, which comprises the following steps: a workpiece to be processed is fixed on a vertical vibration plate, a milling cutter is adjusted to a processing position, then a four-channel signal-generator is turned on , an electric signal generated by the four-channel signal-generator is transmitted to a four-channel power amplifier, after the electric signal is amplified by the four-channel power amplifier, and then is output in a vibrating table, the electric signal is received by the vibrating table, transverse single-direction vibration, vertical single-direction vibration, and transverse and vertical bidirectional vibration are realized by a vertical piezoelectric ceramic oscillator and a transverse piezoelectric ceramic oscillator which are arranged in the vibrating table, the workpiece to be processed is driven for one-dimensional or two-dimensional mechanical oscillation, and exciting vibration-aided milling can be carried out on the workpiece. According to the invention, vibration direction precision during the processing step can be greatly increased, stability and processing precision during the vibration processing step can be effectively guaranteed, unidirectional or bidirectional vibration processing can be realized, processing application scope is developed, and processing efficiency is increased.
