Description

[Detailed description of the invention] Road traffic in snowy regions has rapidly developed through modern comprehensive mechanical snow removal operations, and snow removal from general roads and sidewalks has come to be performed almost every day.

However, as a result of this, a lot of dirt and other debris remains on the pavement after the spring snow melts, and the air is polluted by the spring breeze.Although the pavement is washed away with water using water sprinklers, it is not possible to completely remove the accumulated dirt. That is the best policy.

This device was developed to clean the pavement using a rotary snow removal vehicle such as those proposed in Publication of Utility Model Publication No. 45-10935 and Publication No. 51-1156, etc. The vehicle's four-wheel drive system (see Japanese Patent No. 492,250) allows it to turn even in narrow spaces.

Next, this invention will be explained with reference to illustrated embodiments.

First, a rotary snow removal vehicle similar to the one shown in the above publication to which this invention is applied will be described with reference to FIG. 3.4.

This vehicle has connecting portions B and C in front of a drive vehicle A that can be changed on the spot (for example, see the specification of Japanese Patent No. 492250), and connecting portions D and C that correspond to these connecting portions B and C in a removable manner. E is connected and a snow removal device F is installed, and the snow removal device F is moved up and down by a hydraulic device G having a cylinder attached to an arm. The lever is used to operate the hydraulic system G, that is, to perform hydraulic control via a hydraulic circuit (not shown).

The snow removal device F is separated from the snow removal blade (auger) H, its power source engine and snow removal shoe I, and is connected to the engine power bar J.
The engine inside rotates the auger H via the chain inside the chain case K, and the snow is powerfully discharged through the snow removal shoe I.

The snow removal device F is provided with a snow cutting plate L. As shown in FIGS. 1 and 2, the road cleaning device according to this invention utilizes the above-mentioned rotary snow removal vehicle, and an operating head 3 is attached to the front of the driver's seat of a rotary snow removal vehicle 2 having a diamond 1. , a roller brush 5 is installed inside the front cover 4 in place of the snow removal blade H of the snow removal vehicle, and a raking rubber 6 is installed, and a dirt rake 7 is installed in front of the front cover 4.
It was designed to provide a.

This earth and sand rake 7 has the effects of preventing danger from cleaning work, raking up fixed earth and sand, and increasing the working efficiency of the roller brush 5.

The roller brush 5 can be replaced with a roller having a large number of brushes on its circumference for the snow removal blade H, or a retainer with brushes 5a along the blade of the snow removal blade H as shown in FIGS. 5 and 6. The member 5b can be attached using bolts 5C.

Further, a blower 8 as shown in FIG. 7 is installed behind the roller brush 5 to suck up the garbage and dirt scraped by the roller brush 5, and is used instead of the snow removal chute I of the snow removal vehicle. A provided hose 9 is connected between the blower 8 and a dirt separation chamber 10 provided at the rear of the snow removal vehicle 2.

The sediment separation chamber 10 includes an air vent 13 having a lower tank 11 for storing garbage, sediment, and a lid 12 for releasing air through a filter.

A damper 1 is rotatably attached to the lower tank 11.
4 is provided.

With the above configuration, when the engine installed in the snow removal device F of the snow removal vehicle is driven, the roller brush 5 and blower 8 are activated, and the dirt is collected by the dirt rake 7, roller brush 5, and scraping rubber 6. The soil and sand are sucked and discharged by the blower 8, which is constantly rotating at high speed, and are sent to the soil separation chamber 10 through the hose 9, and the air is discharged to the outside through the air vent 13 after passing through the filter.
Earth and sand etc. are stored in the lower tank 11.

When removing earth and sand, the damper 14 is used to load the earth and sand into the destination or onto a transport vehicle.

As explained above, according to this invention, it is possible to collect and remove garbage and dirt by using a rotary snow removal vehicle during snow melting after snow removal.
