Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0026] figure 1 It is an overall view showing an example of a road sweeper. In the road sweeper 1, a rear chassis (cbassis) 2 is mounted with a drive source storage unit 3 in which an engine for work, a suction blower, etc. are installed, and The hopper 4 for storing the dust D is provided with a dust recovery device 10 behind the hopper 4 . Symbol 5 is a known side brush arranged on the left and right sides of the chassis 2 between the front and rear wheels 6, 6. The side brush 5 is used to sweep the dust D on the road surface to the central side in the width direction of the vehicle. The main brush 11 at the lower end of the dust recovery device 10 sweeps up the dust D, transports it upward in the dust recovery device 10 , and throws it into the hopper 4 . Moreover, the side brush 5 is covered with the side brush cover 5a, and scattering of dust can be prevented. ...

Abstract

In a dust recovery device, a rotation shaft at the upper side of a rotary type conveyor is set to movable vertically. Furthermore the rotation shaft at the upper side and a guiding component are connected through a connecting mechanism which sustains the guiding component to a certain position relatively to a rotation shaft at the upper side so that the guiding component is interlocked with the vertical movement of the rotation shaft at the upper side. Therefore, presetting a clearance between a conveying oar and the guiding component is not required in setting an adjusting mechanism of an annular member. Furthermore an excellent conveying efficiency for dust, etc. can be obtained.

Description

technical field [0001] The present invention relates to a dust recovery device, which is arranged at the rear of a road sweeper, and is used to recover dust on the road surface into a hopper arranged on the upper part of the road sweeper. Background technique [0002] Known as a dust recovery device is the following configuration: as shown in Japanese Patent Application Laid-Open No. 2002-194719 (Patent Document 1) of the applicant's Japanese patent application, the dust collector is arranged behind the rear wheels of the vehicle and swept forward. A vertical rotary conveyor (conveyor) is installed in front of the main brush (brush) for dust, etc. With these rotary conveyors and counter-rotating paddles, the dust and the like swept up by the main brush can be transported upward and thrown into the hopper above the vehicle. [0003] also, Figure 9 (A) shows that the dust recovery device 70 of counter-rotating paddles is set above the rotary conveyor, and the rotary conveyor...
