Background

The deep ploughing and loosening is to utilize equipment to carry out deep ploughing and smashing on the soil, so that soil layers cannot be disturbed after the deep ploughing and loosening, nutrients, moisture and oxygen of the soil can be expanded after the deep ploughing and loosening, and the productivity is improved. The existing deep scarification ploughs mainly have two kinds, one kind is to drive the deep ploughing through the tractor and smash the head that loosens the soil, one kind is to drive the deep ploughing through the newly developed walking machinery and smash the scarification case, and this kind of machinery mainly includes running gear, frame, driver's cabin, driving system and deep ploughing smashes the device that loosens the soil. The two kinds of travelling mechanisms of the loosening and tilling machine are two kinds, one is a wheel type travelling mechanism, and the other is a crawler type travelling mechanism with two crawler belts on two sides.

For the wheel type travelling mechanism, in the loosening and ploughing process, the ground is uneven, the cutter extends into the soil, and the soil has certain resistance to the cutter, so that the whole equipment is greatly vibrated and greatly damaged, and in addition, the loosening and ploughing depth of the cutter can be changed according to the bumping of the equipment, so that the loosening and ploughing depth is inconsistent; in the process of climbing and descending the slope, the wheel type subsoiler needs to lift the cutter higher to prevent the cutter from interfering with soil, in addition, when the equipment moves to the top of the slope, the front wheels firstly enter the lower slope surface, the rear wheels are also arranged on the upper slope surface, and if the slope is too large, the top of the slope is arranged on the rack, so that the equipment cannot walk.

A floating type loosening and plowing ridge smashing machine is disclosed in a patent document with the Chinese application number of 201810036210.4 and the publication number of 2018.7.3; the loosening and smashing ridge machine comprises a front traction part, a floating connecting device, a rear floating device, a connecting device and a smashing ridge device; the front traction part comprises a front triangular crawler belt travelling mechanism, a front frame, a power device and a cab; the floating connecting device comprises a front connecting frame, a rear connecting frame and a joint bearing, wherein the front connecting frame is connected on the front rack, the rear connecting frame is connected on the rear rack, the joint bearing is connected between the front connecting frame and the rear connecting frame, and a buffer oil cylinder is hinged between the front rack and the rear rack; the rear floating device comprises a rear triangular crawler belt travelling mechanism, a rear rack, a hydraulic oil tank and a cooler; the connecting device is hinged on the rear frame, and the ridge smashing device is hinged on the connecting device.

However, the frame of the loosening and crushing ridge machine is directly and fixedly connected with the front triangular crawler belt traveling mechanism; when the vehicle travels, the vibration generated by the front triangular crawler traveling mechanism can be directly transferred to the rack and further transferred to the cab, so that the construction of operators is influenced; frequent vibration can cause unstable connection among the devices and shorten the service life of the loosening and tilling ridge smashing machine; in addition, the front connecting frame and the rear connecting frame of the loosening and tilling ridge smashing machine are hinged through a conventional joint bearing, and the rear floating device is not easy to reset and is easy to block.
