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

A subsoiling smash-ridging machine, characterized in that, it comprises a machine body, a smash-ridging device and a connection device;

• the machine body comprising:
• a walking mechanism, a chassis, a diesel engine component, a hydraulic oil tank, a cooler and a driving cab;
• wherein the chassis is mounted on the walking mechanism, the diesel engine component, the hydraulic oil tank and the driving cab are mounted on the chassis, and the cooler is mounted on the hydraulic oil tank;
• the smash-ridging device comprises a smash-ridging box, a driving mechanism, a bearing, transmission shafts, power input members and a spiral drill rod;
• the smash-ridging box 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 length of the lower bearing seat is larger than that of the upper bearing seat, and a bearing is mounted in the upper bearing seat;
• the driving mechanism is mounted on the top plate and drives the transmission shafts to rotate;
• the transmission shafts are mounted between the bearings located within the lower bearing seat and the bearing located within the upper bearing seat, and the lower ends of the transmission shafts extend out of the smash-ridging box;
• each power input member is mounted on the transmission shafts, the lower surface of each power input member abuts against the shaft shoulders of the transmission shafts;
• the spiral drill rod is mounted at the lower ends of the transmission shafts;
• and the connection device is connected between the chassis and the smash-ridging device.
