Description

(54) BULK MATERIAL DISTRIBUTOR

I

The invention is intended to care for the coating of roads at low temperatures during the ice.

A well-known bulk material dispenser contains a hopper mounted on the chassis of a base machine with a longitudinal separation partition and at least one scraper-belt conveyor with traction chains, a mixer and a spreading device 1.

The disadvantage of this device is unproductive consumption of the century, due to the low accuracy of their dosing.

 The purpose of the invention is to reduce the consumption of additives by increasing the accuracy of dosing.

This is achieved by the fact that in the distribution of 5 bulk materials containing a bunker mounted on the chassis base mashina with a longitudinal dividing partition and at least one scraper belt conveyor with traction means, a blender and a spreading device, each scraper of the conveyor is made composite of the hinged parts, installed with a gap relative to each other for the passage of the longitudinal partition, and connected by means of hinges with the traction chains, on which the transport tape is fixed ortera.

FIG. 1 shows a schematic diagram of the bulk material dispenser; in fig. - the same, rear view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 3; in fig. 5 - scraper-belt conveyor; in fig. 6 is a sectional view BB in FIG. five.

The bulk material dispenser consists of a hopper 2 with a longitudinal dividing wall 3 and a scraper-belt conveyor 4 with traction chains 5, a blender 6, a spreading device 7 with a protective apron 8 and a dressing limiter 9 mounted on the right machine 1. On the back wall of the bunker 2 mounted adjusting shchybery 10 with drives 11, and the gates, 10 are lined with a protective elastic coating 12.

Claims (1)

The bunker 2 is closed on top by a safety grid 13 and an awning 14, and on its Middle wall is mounted a ladder 15 for the service personnel and a casing 16 is fixed in which the mixer 6 with a drive 17 and a diverter 18 are placed, spreading tools 7 with a drive 19. In the bottom of the bunker 20 2 a scraper ribbon conveyor 4 is installed in the form of hauling chains 5 with driving sprockets 21. Independent parts 23 and 24 of the scraper are mounted on the hauling chains 5 by means of hinges 22, which are interconnected by means of a hinge 25, and a conveyor belt 26 is fixed EPA 4, wherein for the connecting govymi chains 5 are guides 27 in contact with the rollers 28, mounted on independent portions of the scrapers 23 and 24. Works bulk material dispenser as follows. Before starting work, the compartments of the hopper 2 are loaded with bulk material and additives and, depending on the density of the dressing, they pick up the speeds of movement of the base mashina and conveyor 4. The delivered materials are placed on the belt 26 between the scrapers, and for the dosing of components within the specified limits the scrapers are made in the form of hinged and independent from each other, parts 23 and 24, installed with a gap between them and changing. The height due to the rotation around their axes by an amount depending on the position of the adjusting shchyberov 10. Prot The entire length of the hopper 2. The scrapers, when moving with the material, do not change their vertical position, which is ensured by installing their 27 directions at some distance from the bottom 20 of the bunker, along which the rollers 28 are located at the bottom of the scraper. axes (their deviation) before approaching the end of the guides 27. When approaching the location of the hooks, the guide 27 ends, and the scraper means that it is possible to deviate with a contact with the hook 10. The amount of deflection of the scraper depends on the size of Zor Mezhuyev schiberom 10 and conveyor belt 26. As the scraper consists of scharnirno Connections parts, for each part can be set hopper Mezhuyev ribbon 26 desired gap 10 and schiberom and receive, respectively, the desired sootnoolenie mixture. After passing through the sponge 10, the material moves downstream, first hit the mixer 6, where it is pre-displaced, then further along the discharge 18 onto the spreading device 7, which spills the material onto the road surface with a given density. The use of the invention will significantly improve productivity, improve the quality of work, reduce the energy and metal consumption of the structure, reduce material overhead. Claims of the invention Bulk material distributor, containing a hopper mounted on the base sheet with a longitudinal partitioning wall and at least one scraper-belt conveyor with traction chains, a mixer and a spreading device, characterized in that, in order to improve the consumption of additives by increasing the metering accuracy, each conveyor scraper is made of a composite of hinged parts mounted with a gap relative to each other for the passage of a longitudinal partition and and is connected by scharnirov with m govymi chains, in which the conveyor belt is fastened.
