Extended-type subsoiling smash-ridging machine and subsoiling smash-ridging machine

A smash-ridging device of a subsoiling smash-ridging machine, characterized in that, it comprises a bottom plate, side plates and a top plate, the lower end surfaces of the side plates are welded on the bottom plate, and the top plate is welded on the upper end surfaces of the side plates;

• at least two lower through-holes are formed in the bottom plate, lower bearing seats extending upwardly are welded on the inner walls of the lower through-holes, the lower bearing seats protrude from the upper surface of the bottom plate, the height of protruding part of the lower bearing seat is larger than the width of two bearings, bearings are mounted in the lower bearing seats, rib plates are welded between adjacent lower bearing seats, and there are lubricating oil passages between the rib plates and the bottom plate;
• at least two upper through-holes corresponding to the lower through-holes in the vertical direction are formed in the top plate, an upper bearing seat extending downwardly is arranged on the inner walls of the upper through-holes, the height of the lower bearing seat is larger than that of the upper bearing seat, a bearing is mounted in the upper bearing seat,
• a driving mechanism is mounted on the top plate and drives the transmission shaft to rotate;
• a transmission shaft is mounted between the bearings located within the lower bearing seat and a bearing located within the upper bearing seat and the lower ends of the transmission shafts extend out of the smash-ridging box;
• power input members are mounted on the transmission shaft and the lower surface of each power input member abuts against the shaft shoulders of the transmission shafts;
• and
• a spiral drill rod is mounted at the lower ends of the transmission shafts.
