Road construction machines of the paver or feeder type

Abstract

The invention relates to a paving machine (1) or feeder (9) with a chassis (6) driven by a drive unit (4) and in the working direction ( The front part of a) is provided with a hopper (5) comprising a hopper side wall (14) extending along the working direction (a) and a pivot axis ( S) an inclined discharge flap (22), the discharge flap (22) comprising a flap bottom (12) and extending adjacent to the hopper side wall (14) and fixed to the flap bottom (12) The flap side wall (16) on the flap, the flap side wall (16) is supported to be able to move relative to the hopper side wall (14), and a protective cover (21) is arranged on the hopper side wall (14) ), the protective cover is engaged at least partially around the edge of said flap side wall (16).

Description

technical field [0001] The invention relates to a road construction machine of the paving or feeder type. Background technique [0002] In road construction, for example, conventional paving machines or feeders, hereinafter collectively referred to as road construction machines, are used to lay base layers, such as concrete or asphalt layers. If the paving material is laid with a paving machine, the feeder acts as an intermediate storage device for transporting the paving material during the paving process. During the paving process, the paving machine is supplied with paving material directly from a transport vehicle, such as a truck, or via a feeder. When a feeder is used, the feeder is supplied with paving material by a transport vehicle and conveys said paving material to the paving machine by suitable conveying means, usually a conveyor belt. These road construction machines are usually self-propelled. Both pavers and feeders have a frame and an undercarriage, for ex...

AI Technical Summary

Problems solved by technology

In this way, the intrusion of additional paving material between the two side walls is facilitated, resulting in a further increase in the gap between the side wall of the flap and the side wall of the hopper

In this way, the paving material on the one hand falls from between the side walls of the hopper and the side walls of the flap to the ground

On the other hand, paving material can become blocked between the side walls of the hopper and the side walls of the flap, resulting in a blockage of the side walls of the flap or of the discharge flap itself, whereby its function is limited

Perpetually clogged paving material can deform the discharge flap in this area and thus be damaged
