Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled outdoor cleaning device that moves outdoors to clean the ground surface (recover deposits).

Environmental pollution, health hazards, and the like may occur due to scattering of powders (dust) generated at factories, construction sites, and the like. In particular, at sites where ore, coal, limestone, grain, cement, etc. are handled, if these granules fall to the ground surface and are left unattended, they will scatter around, requiring regular cleaning work. This was a burden on workers.
For example, in Patent Document 1, a device main body that can travel on a road surface is provided with a cleaning member that collects deposits on the road surface as the device main body travels with its lower end in contact with the road surface, via a holding mechanism. The cleaning member is kept in a state (cleaning work state) in contact with the road surface by its own weight, and moves up and down according to the unevenness of the road surface to be cleaned. Alternatively, a deposit cleaning device is disclosed which can move vertically and tilt in the width direction of the device body.
On the other hand, in Patent Document 2, a pedestal for receiving fine powder dropped from the belt is provided in at least the first half of the return path of a belt conveyor that conveys bulk materials such as ore, coal, limestone, grains, and cement. A fallen powder recovery device for a belt conveyor for bulk materials, provided with a scraper that is installed and reciprocates in the longitudinal direction along the upper surface of the cradle to scrape and discharge the falling fine powder to the end of the cradle. is disclosed.
Further, Patent Document 3 discloses an ore recovery device that scrapes and recovers ore falling from a belt conveyor that conveys bulk materials with a plate-like scraper attached to an endless conveyor chain. An ore recovery device is disclosed in which a comb-teeth scraper having comb-shaped protrusions for scraping off ore deposits deposited on a conveyor chain is attached to a conveyor chain.

However, in Patent Document 1, the cleaning member that collects the deposits has a structure that moves up and down according to the unevenness of the road surface to be cleaned. I had a problem that I couldn't do it. Also, if the sediment is solidified due to moisture content, etc., or if the granular material that is the source of the sediment is in small gaps (recesses) on the road surface, the cleaning member alone will not be sufficient. There was a problem that it could not be collected. Furthermore, since it is a system in which it moves (runs) on wheels, it is susceptible to uneven road surfaces and lacks stability in running.
On the other hand, the devices of Patent Documents 2 and 3 are both dedicated to a belt conveyor that conveys bulk materials, are installed (fixed) below the belt conveyor, and use a scraper to scrape the granular materials falling from the belt conveyor at one point. It is collected by raking it.
Therefore, in the devices of Patent Documents 2 and 3, only powder particles that have fallen below (directly below) the belt conveyor can be recovered, and powder particles that have fallen around the belt conveyor and places other than the belt conveyor (outdoors) There was a problem that it was not possible to deal with bodies (deposits), and the places where it could be used were limited.
