Device capable of realizing diameter fixed-length automatic sawing-off, sorting and processing on tapered round stock

The invention relates to the technical field of processing equipment for tapered round stock such as bamboos. In order to solve the problems that product specification is various and quality is poor as diameter sectional fixed-length sawing-cutting cannot be really realized during existing processing for tapered round stock such as bamboos, the invention provides a device capable of realizing diameter fixed-length automatic sawing-off, sorting and processing on tapered round stock, and the device comprises a loading assembly, a supporting assembly, a truss mechanical hand assembly, a sawing table assembly, a sorting assembly and program control units for separately controlling the loading assembly, the supporting assembly, the truss mechanical hand assembly, the sawing table assembly and the sorting assembly to act, which are sequentially arranged according to a processing sequence. The processing device disclosed by the invention can realize diameter fixed-length automatic sawing-off,automatic sorting and pa
