Extended Type Subsoiling Smash-Ridging Machine and Subsoiling Smash-Ridging Machine

摘要

Disclosed is an extended-type subsoiling powder ridge machine, comprising a machine body (1), a powder ridge device (2), a connecting device (3), a ditching device (4), a levelling device (5) and a straw returning device (6), wherein the powder ridge device (2) comprises a powder ridge box (21), the powder ridge box (21) comprises a base plate (211), a side plate (212) and a top plate (213), lower bearing seats (271) are installed on the base plate (211), a rib plate (273) is welded between the lower bearing seats (271), a lubricating oil channel is provided between the rib plate (273) and the base plate (211), and an upper bearing seat is installed on the top plate. The extended-type subsoiling powder ridge machine can improve the strength of the lower bearing seat, with more bearings being installed at the position under a large amount of stress and less bearings being installed at the position under a small amount of stress, so as to improve the rigidity and transmission stability of a transmission shaft and to reduce costs. The rib plate is welded, and the smooth flow of lubricating oil in the powder ridge box is guaranteed, so as to improve the lubricating effect thereof.
