Detailed Description

The following describes the inventive embodiments in detail with reference to the drawings. The utility model provides a saw bit formula hobbing cutter and gear formula hobbing cutter combination road surface ice crushing roller, includes roller 2, and hydraulic motor 1 is joined in marriage on roller 2 one side tip, and roller 2 rotatable mounting is on two supporting seat 3 of relative disposition, on roller 2, be located the position department between two supporting seat 3 and be equipped with gear formula hobbing cutter assembly 4 and saw bit formula hobbing cutter assembly 5 in proper order interval, saw bit formula hobbing cutter assembly 5 axial, radial location, the rotatable suit of circumference are on roller 2, gear formula hobbing cutter assembly 4 is adorned on roller 2 admittedly, and the whole gear formula hobbing cutter assembly 4 of admitting on roller 2 is the spiral arrangement configuration along its axis whole; the saw blade type hob assembly 5 is composed of semicircular saw blade cutters 6, a supporting plate 7, a bearing 8, a fastener set 9 and a reinforcing plate 10, wherein the reinforcing plate 10 and the supporting plate 7 are fixedly arranged on the outer annular surface of the bearing 8 in an opposite mode, the supporting plate 7 is positioned at a position between the oppositely arranged reinforcing plates 10, two semicircular saw blade cutters 6 are symmetrically arranged at the outer position of the circumferential outer end surface of the supporting plate 7, the semicircular saw blade cutters 6 are in contact fit with the supporting plate 7, the reinforcing plate 10 and the semicircular saw blade cutters 6 are fixedly arranged by the fastener set 9, the gear type hob assembly 4 comprises a pin shaft 11, a star-shaped support 12, a sleeve frame 13, a gear hob 14 and a pressure spring 15, the sleeve frame 13 is movably sleeved on each support arm of the star-shaped support 12 through the pin shaft 11, the gear hob 14 is rotatably arranged on the outer end part of the sleeve frame 13, the pressure spring 15 is assembled on the inner side of the sleeve frame 13, and two ends of the pressure spring 15 are respectively in contact fit with the star-shaped support 12 and the sleeve frame 13.

During operation, the hydraulic motor 1 drives all gear type hob assemblies 4 fixedly mounted on the roll shaft 2 to actively rotate through the roll shaft 2, the gear hob 14 on the gear type hob assemblies 4 in spiral linear arrangement is smashed and rolled on ice in sequence, machine vibration is small, the gear hob 14 after smashing the ice is instantly rotated along with the advancing of the whole machine, ice cubes on a road surface are smashed and cut off rapidly, when the gear hob 14 hits a hard road surface after smashing and cutting an ice layer, under the control of the pressure spring 15, the gear hob 14 can automatically stretch and retract on the casing frame 13, and the road surface and the machine are protected from being damaged.
