Municipal old road milling device

Abstract

The invention discloses a municipal old road milling device, and relates to the field of pavement maintenance, the old municipal road milling device comprises a treatment box, the top of the treatment box is provided with a driving assembly, the inner walls of the two sides of the treatment box are rotatably provided with rotary drums, and the two sides of the outer side walls of the rotary drums are fixedly provided with a plurality of support connecting plates which are distributed at equal intervals. Through the arrangement of the driving assembly, the transmission assembly, the rotary drum, the crushing rollers and the milling wheels, the driving assembly provides power to enable the rotary drum to rotate, the rotary drum rotates rapidly, and the milling wheels and the crushing rollers which are distributed on a supporting connecting plate and a supporting mounting plate at equal intervals are made to rotate through the transmission assembly; the transmission assembly enables the rotating speed of the crushing roller to be higher than that of the milling wheel and the rotating directions of the crushing roller and the milling wheel to be opposite, the milling wheel mills a road surface, particles are generated and thrown between the crushing roller and the rotary drum to be crushed, the rotating speed of the crushing roller is higher than that of the milling wheel, so that the situation of material blockage is avoided, and cement crushed into particles is thrown to the rear part by the whole rotary drum.

Description

technical field [0001] The invention relates to the field of road surface maintenance, in particular to a milling device for old municipal roads. Background technique [0002] Road surface milling is a method of scraping the damaged old road surface and then laying a new surface layer. Generally, it is to eliminate the damaged loose parts of the old road surface, or to combine the old and new surfaces well, and to improve the smoothness of the road surface. Milling off the upper layer The uneven part is to improve the flatness of the lower layer (on the premise that there are no major problems in the base layer of the road surface). It is generally used in the middle repair of the road and the damaged loose part of the old road surface in a relatively large range, and there is local congestion (accumulation) on the old road surface. (soil) containing oil and diseased areas, milling off the uneven part to lay a new layer to improve the smoothness of the road surface, or for a...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, during the process of milling old roads in general municipal roads, a large number of cement fragments will be produced. These fragments are of different sizes and often need to be re-broken before they can be recycled. Fine particles cannot be directly produced during the milling process, and need to continue to be crushed and cannot be recycled directly. Therefore, we have disclosed the old road milling device for municipal roads to meet people's needs
