Title:
DUST SUCTION STRUCTURE OF ENGINEERING VEHICLE FOR PERMEABLE PAVEMENT PORE MAINTENANCE
Document Type and Number:
WIPO Patent Application WO/2021/013151
Kind Code:
A1
Abstract:
Disclosed is a dust suction structure of an engineering vehicle for permeable pavement pore maintenance. A dust suction mechanism (10), a dust suction plate (20) and a lifting transfer apparatus (30) are provided on a vehicle body (40), wherein the dust suction mechanism (10) comprises an electromechanical device box (11) and a dust collection tank (12), and is connected to the dust suction plate (20) through a dust suction pipeline (13); the dust suction plate (20) is hung in front of the vehicle body (40) through the lifting transfer apparatus (30), and a dust suction cover (21) is provided at the bottom of the dust suction plate; the lifting transfer apparatus (30) comprises a base (31), a cantilever (32), an oil pressure device (33) and a rotary disk (34); the base (31) is integrated on the rotary disk (34) at a front end of a chassis of the vehicle body (40), and one end of the cantilever (32) is pivotally connected to the base (31), and is connected by the oil pressure device (33); a toothed disk (35) is provided on a disk surface of the rotary disk (34), and the toothed disk (35) and a driving rod (36) are engaged with each other; and the rotary disk (34) is driven by the driving rod (36) to generate an action, such that the cantilever (32) can move up and down, and transversely move left and right. When the dust suction structure is used, the dust suction cover (21) of the dust suction disk (20) is attached onto a permeable pavement, and the dust suction mechanism (10) is used to suction out blockages in pavement pores, so as to achieve the effect of permeable pavement maintenance.
