The working principle of the ice-breaking and snow-pushing rolling shovel installed on the small tractor described in the utility model is as follows:

During work, a kind of frame backboard 18 that is installed in the ice-breaking and snow pushing shovel described in the utility model on the small-sized tractor is fixed on the front end of the small-sized tractor 48, the small-sized tractor output pulley 47 grooves and the rolling ice-breaking mechanism. A belt No. 2 No. 46 is installed between the outer wheel grooves of the transition pulley 33, and a belt No. 1 No. 45 is installed between the inner wheel grooves of the transition pulley 33 and the wheel grooves of the input pulley 32. The output pulley of the small tractor 47 drives transition pulley 33 to rotate through belt No. 2 No. 46, and the rotation of transition pulley 33 drives input pulley 32 to rotate, and then makes transmission shaft 41 in ice-breaking roller 26 rotate, and transmission shaft 41 utilizes flat key connection to make ice-breaking roller 26 and the eccentric wheel 42 rotate, and the drive shaft 41 drives the eccentric wheel 42 to rotate. Every time the drive shaft 41 rotates once, a mechanical vibration is generated at two symmetrical positions inside the ice-breaking roller 26 at the same time. The natural frequency of the ice layer, the ice layer will resonate, thereby breaking naturally, one end of the lead screw 11 in the lifting mechanism of the rolling ice breaking mechanism is connected with the torque DC motor 9 with bolts through the elastic pin coupling 10, and the torque DC motor 9 Powered by a small tractor battery, when it rotates, the slider 16 on the lead screw 11 slides in the lead screw sleeve 14, thereby pulling the long strut 15, and the long strut 15 raises or lowers the height of the suspended shaft, and finally The shaft 24, the short pole 25 and the spring damping rod 23 jointly drive the ice-breaking roller 26 to reciprocate in the vertical direction. The ice-breaking roller 26 is a hollow ring cylindrical structure, and the ice-breaking roller 26 is welded with uniform The distribution of hemispherical protrusions has a large number of dot-shaped pits on the protrusions. When the ice-breaking roller 26 rotates at high speed, due to the effect of the external protrusions of the ice-breaking roller 26, the space between the protrusions and the ground is continuously reduced, and the air is continuously compressed. When the tangent plane of the protrusion apex is parallel to the ice surface, the minimum value of compression will be reached. At this time, the air has the maximum compression potential energy and certain kinetic energy. Evenly distributed, it will generate continuous ice-breaking air energy and play the role of breaking the ice layer. The dimples on the protrusions can prevent snow from sticking to the ice surface with floating snow, thereby effectively reducing the running resistance of the unit and improving Working efficiency: when the snow pusher 1 encounters an obstacle, the piston rod of the hydraulic cylinder 5 in the snow pusher telescopic mechanism shrinks, and the snow pusher 1 turns upwards with the axis of the shaft pin as the center line, avoiding the obstacle, Then, driven by the hard spring 34 and the piston of the hydraulic cylinder 5 is elongated, an appropriate snow removal position is reached; The piston rod of 5 shrinks, and when the road recovers flat, it returns to the normal snow removal position under the drive of the hard spring 34 and the piston effect of the hydraulic cylinder 5; when running into a downhill section, it is opposite to the above process.
