Pavement grooving machine

Abstract

The invention discloses a pavement grooving machine. The pavement grooving machine comprises a body, a traveling wheel, a cutter disk, a lifting mechanism and a dust removal device, wherein the dust removal device comprises a dustproof cover, a cyclone dust collector and an air pump; the cyclone dust collector comprises an outlet filter region, a cyclone separator and a dust precipitation region; a partition plate is arranged between the outlet filter region and a vortex air inlet region; the outlet filter region and the vortex air inlet region are communicated with each other through a circular communication pipeline; the vortex air inlet region comprises a vortex part and a dust collector air inlet part which is externally tangent to a main body part; the dust collector air inlet part is connected with an air outlet of the dustproof cover; a filter screen is arranged in the outlet filter region. Sucked dust-containing air is centrifugally precipitated in the cyclone separator, enters the outlet filter region through a connection pipeline and is re-filtered, so that the aims of centrifugal dust removal and filtration are achieved; the situation of blocking or replacement of a filter bag can be avoided after the pavement grooving machine is used for a long time; light impurities can be filtered out through the filter screen, and the air pump is prevented from being blocked. Therefore, the pavement grooving machine is reasonable in structure, good in dust removal effect, high in working efficiency and low in using cost.

Description

technical field [0001] The invention relates to a road surface maintenance machine, in particular to a road surface slotting machine. Background technique [0002] We know that when the pavement grooving machine grooves and protects the cracks on the pavement, a large amount of dust is generated, which will have a great impact on the operator's body and the surrounding environment. At present, the general slotting machine does not have a dust removal device, but for a small number of slotting machines with a dust removal device, the dust removal device is basically carried out by filtering, which forms a negative pressure by vacuuming to achieve collection. The dust is filtered through the filter bag and then discharged. When this filter type dust removal device is in use, the dust sucked in by the vacuum is likely to block the small holes of the filter bag and affect the dust removal effect, which leads to the need for frequent cleaning or replacement of the filter bag, re...

AI Technical Summary

Problems solved by technology

When this filter type dust removal device is in use, the dust sucked in by the vacuum is easy to block the small holes of the filter bag and affect the dust removal effect, which leads to the need for frequent cleaning or replacement of the filter bag, resulting in a decrease in work efficiency and an increase in use costs.
