Saw blade type hob and gear type hob combination road ice crushing roller

Abstract

The invention relates to a saw blade type hob and gear type hob combination road ice crushing roller, and belongs to environmental protection machinery. Gear type hob assemblies and saw blade type hobassemblies are arranged at intervals between two supports seats on a roller shaft, and the saw blade type hob assembly is axially and radially positioned and circumferentially and rotatably sleeved on the roller shaft; the gear type hob assembly is fixedly arranged on the roller shaft, and all the gear type hob assemblies fixedly arranged on the roller shaft are spirally arranged along the axis as a whole; the saw blade type hob assembly comprises a semicircular saw blade, a support plate, a bearing, a fastener group and a reinforcing plate, and the gear type hob assembly comprises a pin, a star-shaped bracket, a sleeve rack, a gear hob and a compression spring. The roller has the advantages of novel and reasonable structure, strong operation adaptability, good operation quality, high removal efficiency, low damage to road, reliable use, and few failures.

Description

technical field [0001] The invention belongs to environmental protection equipment, and mainly relates to an operation assembly for removing ice and snow from road surfaces. Background technique [0002] At present, there are many kinds of ice and snow removal machines on the road surface, which can basically meet the requirements of the removal operation for the compacted ice and snow layer and ordinary thick ice layer on the road surface. But, for the thin ice layer that freezes after raining, and the hard ice that automobile exhaust freezes into and the half-frozen and half-thawed black ice that is made up of ice water, that is collectively referred to as "stubborn ice", existing methods such as hitting Equipment such as beating type, pick planing type, milling type, drum type, hob rolling type, and crankshaft ice chopping type are not applicable. It is easy to cause damage to the road surface only by the operator's control, which has become a problem in clearing ice on ...

But, for the thin ice layer that freezes after raining, and the hard ice that automobile exhaust freezes into and the half-frozen and half-thawed black ice that is made up of ice water, that is collectively referred to as "stubborn ice", existing methods such as hitting Equipment such as beating type, pick planing type, milling type, drum type, hob rolling type, and crankshaft ice chopping type are not applicable. It is easy to cause damage to the road surface only by the operator's control, which has become a difficult problem in the world's road ice removal.

The existence of stubborn ice makes the road surface as smooth as a mirror, making it very difficult to walk, which can easily cause many major traffic accidents, and even cause urban traffic paralysis
