Abstract

The invention discloses a vibration digging knife device. The device comprises a chassis connecting frame, a knife part, a vibration amplifying part and a vibration part; a blade is toothed so as to reduce the work resistance and increase the shoveling and cutting force on root hair of underground roots and stems; the blade can also be vertically bent slightly by using a pincer-like tool so as tochange the angle of inserting a digging knife into soil; the eccentricity of an eccentric bearing can be appropriately enlarged through a fixed fork plate so as to enhance the digging strength of thedigging knife; pin shafts are all additionally provided with wearable bushes to prolong the service life of the device.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a vibrating digging knife device. Background technique [0002] For the harvesting of underground root crops, digging knife technology is the most basic and core technology, among which vibration digging knife is the most widely used. However, existing knives have problems such as small excavating knife vibration amplitude, non-adjustable entry angle, large vibration of the complete machine, and excessive wear of parts and components. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a vibrating excavating knife device, which is small in size, light in weight, simple in structure and low in cost, and a plurality of such devices can be used in series with a set of power devices. [0004] The technical solution adopted in the present invention is: a vibrating digging knife device, including a chassis connection...
