Abstract

The invention relates to the maintenance and repair of the carriageway of highways and allows for the provision of road surface repairs. This is achieved by the fact that the feed bin in the gritter is provided with an additional bottom and an inclined distribution tray, located respectively above and below the rear ends of the scraper conveyors. The additional bottom is fixed at the end of the gabled dissector. Inclined distribution tray mounted on the end of the main bottom. 6 Il.

Description

The invention relates to the maintenance and repair of the carriageway of highways.

The aim of the invention is to provide the possibility of road bedding.

FIG. 1 schematically shows a sand spreader, general view; Figure 2 - the same, with the elevated top of the feed hopper; on fig.Z - section aa in figure 1; figure 4 - node I in figure 1; Fig 5 is a fragment of the rear part of the feed bin, axonometric; fig 6 is the same, bottom view.

The sand spreader consists of a folding back mounted on the chassis 1 by means of hydraulic cylinders 2 of the feed bin 3 with a dual-speed divider 4 installed on its bottom along the longitudinal axis and reversible longitudinal scraper conveyors 5 with a drive in the form of a hydraulic motor 6 connected symmetrically to the last, connected with a reducer 7 s

their front drive sprockets 8, and the chutes 9 are attached to the feed bin 3 under them. Under the chutes 9, spreading devices 10 driven by hydraulic motors 11 are mounted on chassis 1 of the base machine

The feed bunker 3 is provided with an additional bottom 13 located at its rear part and fixed at the end of the dual-slope cutter 4 with tensioning sprockets 12 scraper conveyors 5 and with an inclined distribution tray 14 fixed at the end of the main bottom of the feed hopper 3.

Sand spreader works as follows.

In order to sprinkle roads with sand and fine gravel in winter, during movement, the bulk material from the feed bin 3 is fed by scraper conveyors 5 into the front part to chutes 9, where it is poured onto the spreading devices 10 and under the action of centrifugal

The force is scattered on both sides of chassis 1.

The filling of quarry roads with rubble of the middle class during basic repair is carried out as follows.

During the movement of the chassis 1, the rubble from the hopper 3 is fed by scraper conveyors (reversible) 5 to the rear end of the feed bunker 3. The crushed stone is fed into the gap between the scraper conveyor 5 and the additional bottom 13 and then dumped onto the distribution chute 14, while the distribution chute 14 sets the necessary bedding width

Claims (1)

The invention claims a sand spreader containing mounted on the chassis of the base machine feed bin with double-sided splitter mounted on its bottom, longitudinal reversible scraper conveyors symmetrically located in relation to it and spreader devices placed under their front ends in the course of movement, in order to ensure that coatings for repairs, the feed bin is provided with an additional bottom and a distribution tray mounted obliquely above and below the rear ends of the scraper conveyors, moreover, the additional bottom is fixed at the end of the dual-sloping dissector and the walls of the bunker, and the distribution tray - at the end of the main bottom.
