Combined cutter head for rotary milling and crushing of road ice and snow layers

Abstract

A combined cutterhead for crushing road ice and snow layer by rotary milling belongs to the field of environmental protection machinery; a rod holder plate is fixed on one side of a cutterhead; a screw rod combination on which a spring seat A, a spring seat B and a pressure spring are sleeved is plugged on the rod holder plate and is able to move axially; a swing rod is hinged on a position, on the same side where the rod holder plate is fixed, of the cutterhead body in a swinging manner; one end of the swing rod is sleeved on the screw rod combination and contacts with one side of the rod holder plate; a tool apron is fixed on the other end of the swing rod through a fastener unit; an elastic cushion pad is arranged on a position between the swing rod and the tool apron in a fitting manner; cutting blades are installed on the tool apron; the cutterhead is novel in structure, reasonable, simple, and light-weight, high in universality, strong in applicability, good in operation effect, stable in operation, low in vibration, less in failure and long in service life.

Description

technical field [0001] The invention belongs to an environmental protection machine, and mainly relates to a working part on a machine tool for removing ice and snow layers on urban road surfaces. Background technique [0002] The traditional centrifugal hammer-type road ice and snow removal machine works better, but the service life is too short, the hammers drop too much, the quality of the work is greatly reduced, the maintenance time is long, and the work efficiency is low. The existing brush-roller road snow blower is only suitable for use under the condition that the snow on the road is not compacted and the snow layer is not frozen. After the snow on the road is compacted or frozen, the Such machines have poor operation effect and low efficiency. In recent years, in order to adapt to the removal of snow on the road after compaction or icing, ice and snow removal machines using integral snow shovel assemblies or with convex roller vibration assembly structures have co...

Problems solved by technology

[0002] The traditional centrifugal hammer-type road ice and snow removal machine works better, but the service life is too short, the hammer falls too much, the quality of the work is greatly reduced, the maintenance time is long, and the work efficiency is low

The existing brush-roller road snow blower is only suitable for use under the condition that the snow on the road is not compacted and the snow layer is not frozen. After the snow on the road is compacted or frozen, the Poor operating effect and low efficiency of similar machines

In recent years, in order to adapt to the removal of snow on the road after compaction or icing, ice and snow removal machines using integral snow shovel assemblies or with convex roller vibration assembly structures have come out. The former has integral snow shovels that enter The compacted or frozen ice and snow layer is difficult inside, the efficiency of snow removal is low, and it does not have the function of profiling along the ground, which is easy to cause damage to the road surface or equipment. The latter has the problems of heavy machine weight, large operating vibration, complex structure, and difficult operation. The problem of inefficiency
