Abstract

[Problem] To provide a street sweeper having suppressed production costs and which achieves lifting and lowering of a dirt recovery device using a simple configuration. [Solution] The present invention includes a lifting / lowering drive means (21) having a configuration whereby one end is connected to a hopper (4) and the other end rotates and lifts / lowers a lift arm (17) connected to the dirt recovery device (6). The position of the lift arm (17) is changed by this lifting / lowering drive means (21) between: a cleaning position at which a main brush (8) of the dirt recovery device (6) is in contact with the road surface; a forwarding position at which the lift arm (17) has been raised together with the dirt recovery device (6) high enough that a pressing section (20) of the lift arm (17) is in contact with a pressed section (28) of a lift frame (25); and a dirt discharging position at which the lift arm (17) has been raised further, and the dirt recovery device (6) has been raised further together with the lift frame (25).

Description

technical field [0001] The present invention relates to a road sweeper including a dust recovery device for collecting dust on the road surface, and more particularly to a road sweeper including a mechanism for raising and lowering the dust recovery device. Background technique [0002] As a conventional road sweeping vehicle, there is a road sweeping vehicle including a dust recovery device disposed at the rear of the vehicle and having a main brush for sweeping dust on the road toward the front of the vehicle, and a hopper. It is arranged in front of the dust recovery device and stores the dust recovered from the road surface. [0003] In addition, as a mechanism for discharging the dust stored in the hopper, there are a rear dump bucket system that discharges the dust toward the rear of the vehicle, and a side dump bucket system that discharges the dust toward the side of the vehicle. In the rear dump method, there is a method in which the hopper is lifted upwards and mo...
