Abstract

The invention discloses a suction sweeping device of a special suction sweeping cart for pavement milling and planing. A dragging device is hinged to a suction cover support through a pull rod, and a suction cover is divided into a plurality of rectangular spaces. Each rectangular space is internally provided with a suction device and reverse blowing devices. A dust removal and material collection device is connected with each suction device and an inlet of an air induction device through pipelines. An inlet of an air gathering chamber is connected with an outlet of the air induction device. The reverse blowing devices are connected with an outlet of the air gathering chamber. All the devices form a circulating air current flowing loop. Compared with a common sweeping cart, the suction sweeping device can effectively suck tiny dust generated during pavement milling and planing, the milled and planed pavement sweeping effect is good, and the bonding quality between layers during subsequent conduction is ensured. Through a four-bar mechanism, an adjusting spring and small supporting wheels, adjustment of the depth of parallelism of the suction sweeping device and the pavement is achieved, upward tension adjustment can also be achieved, the suction sweeping device is in a semi-floating balanced state with the swept pavement during working, the suction sweeping device ascends or descends freely in case of obstacles, and the suction sweeping device can adapt to the conditions of the pavement.

Description

Technical field [0001] The invention belongs to the field of road sweeping machines, and particularly relates to a suction sweeping device of a special suction sweeper for road milling. Background technique [0002] In modern road maintenance, milling machines are commonly used to mill the old pavement, and then add new materials on the milling surface to form a new pavement. A large amount of aggregate and dust remain on the working face after milling affects the bonding strength of the new and old layers. [0003] At present, the suction and sweeping device used in the suction and sweeping vehicle is mainly composed of a disc brush or rolling brush that extends to the outside of the vehicle body and a dust suction device. The disc brush uses rotating motion to sweep the garbage on the curbs, corners, and under the guardrail to the working area of ​​the dust collector to form a garbage belt. When the dust collector passes through the garbage belt, the negative pressure generated ...
