The present invention discloses an extended type subsoiling smash-ridging machine, comprising a machine body, a smash-ridging device, a connection device, a ditching device, a flattening device and a straw returning device, wherein the smash-ridging device comprises a smash-ridging box comprising a bottom plate, side plates and a top plate, lower bearing seats are mounted in the bottom plate, rib plates are welded between the lower bearing seats, lubricating oil passages are formed between rib plates and the bottom plate, an upper bearing seats are mounted on the top plate and the length of each lower bearing seat is larger than that of each upper bearing seat. By adopting the structure of the present invention, the strength of the lower bearing seats can be improved so as to facilitate the mounting of more bearing where the stress is large and less bearings where the stress is small, thereby both improving the rigidity and transmission stability of a transmission shaft and reducing the cost; the welding of the rib plates is facilitated, it is ensured that lubricating oil smoothly flows within the smash-ridging box and the lubricating effect is improved.
A subsoiling smash-ridging machine body, characterized in that it comprises a walking mechanism, a chassis, a diesel engine component, a hydraulic oil tank, a cooler and a driving cab;
A walking mechanism for preventing a lower guide wheel from falling off, characterized in that, it comprises walking mechanisms each of which comprises a wheel stand, a driving wheel, a driven wheel, a lower guide wheel, an upper guide wheel and a crawler;
A crawler frame of a subsoiling machine, characterized in that, it comprises a wheel stand, at least two lower guide wheel accommodation cavities are formed at the bottom of the wheel stand, second mounting holes are formed in the bottom of the wheel stand corresponding to the lower guide wheel accommodation cavities and is a lower open groove;
A spiral type deep-ploughing subsoiling machine, characterized in that, it comprises a vehicle frame, crawler devices, a driving cab, a hydraulic oil tank, a diesel engine component, a connection device, a smash-ridging device and a cooler, at least two sets of the crawler devices are arranged at both sides of the lower part of the vehicle frame, the driving cab, the diesel engine component, the hydraulic oil tank, the cooler and the connection device are arranged on the platform surface of the vehicle frame, and the smash-ridging device is arranged on the connection device.
