Abstract

A magazine moving device of brush type street sweeper truck. A magazine (16) is arranged to move between a dust recovery position on a chassis and a dust discharge position (B) where the dust can be discharged by a lift arm (22). A chain (31) is hung between a first sprocket wheel (29) arranged on a base end of the lift arm (22) and a second sprocket wheel (30), integrated with the magazine (16), arranged at the side of the lift arm (22) near the magazine (16), a pressure cylinder (32, 33) arranged on a support framework (9) is connected on a first sprocket wheel (29). In the dust discharge position (B), the magazine (16) is rotated by the pressure cylinder (32, 33) through first and second sprocket wheels (29, 30) and the chain (31). The pressure cylinder )32, 330 is arranged on the support framework (9), thus a pipe to the pressure cylinder is processed simply and the magazine side is changed to be light.

Description

technical field

[0001] The present invention relates to a brush that moves a hopper between a dust recovery position capable of recovering dust and a dust discharge position capable of discharging dust on a chassis, and is capable of discharging dust from the hopper at the dust discharge position The bucket mobile device of the type road sweeper. Background technique

[0002] The structure described in Unexamined-Japanese-Patent No. 2008-285928 (henceforth "patent document 1") is known about the bucket moving apparatus of a brush-type road sweeper. It rotates the lift arm by extending the 1st and 2nd cylinders, and the bucket is placed on the chassis at the dust collection position in front of the conveyor device. It moves to the rear of the car body through the conveyer device and the upper part of the main brush. At this time, there is a first sprocket coaxially fixed to the fulcrum shaft of the pillar erected on the chassis, and a first sprocket with a diameter ratio co...
