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

Embodiment

[0043] Example: Reference Figure 1-8 The shown milling device for old municipal roads includes a treatment box 1, and a drive assembly is arranged on the top of the treatment box 1. The treatment box 1 can be any box structure in the prior art, such as a metal box.

[0044] A rotating drum 13 is rotatably installed on the inner walls of both sides of the processing box 1, both sides of the outer side wall of the rotating drum 13 are fixedly installed with a plurality of equidistantly distributed support connecting plates, and both sides of the outer side wall of the rotating drum 13 are fixedly installed with a plurality of equidistant distributions. The support and installation plate, each support connection plate located on one side of the drum 13 is evenly distributed between two adjacent support installation plates, and the support connection plate and the support installation plate can be any kind of plate-shaped structure in the prior art , such as sheet metal.

Abstract

The invention discloses an old road milling device for municipal roads, which relates to the field of pavement maintenance. Both sides of the wall are fixedly installed with a plurality of equally spaced support connecting plates. The present invention is provided with a driving component, a transmission component, a rotating drum, a crushing roller and a milling wheel. The driving component provides power to make the rotating drum rotate, and the rotating drum rotates rapidly through the transmission component to make the supporting connecting plate and the supporting mounting plate equidistant. The distributed milling wheel and pulverizing roller rotate, and the transmission assembly makes the rotation speed of the pulverizing roller higher than that of the milling wheel and the rotation direction is opposite. For crushing, because the rotation speed of the crushing roller is higher than the rotation speed of the milling wheel, there will be no jamming, and the cement crushed into particles will be thrown to the rear by the entire drum.

Description

technical field [0001] The invention relates to the field of road maintenance, in particular to an old road milling device for municipal roads. Background technique [0002] Pavement milling is a method of scraping a layer of damaged old pavement and then laying a new surface layer. Generally, it is to eliminate the damaged loose parts of the old pavement, or in order to combine the old and new surfaces well, in order to improve the smoothness of the pavement, mill out the upper layer The uneven part is to improve the flatness of the lower layer (on the premise that there is no major problem in the pavement base), it is generally used in the middle repair of the highway and the loose part of the old pavement is damaged in a relatively large range, and there are local stagnations (accumulation) on the old pavement. In order to improve the smoothness of the road surface by laying a new layer, or to better combine the old and new surfaces, it plays a good role in roughening. ...
