Description

The invention relates to the storage of bulk materials in bunkers, in particular, devices for loading briquettes into storage bins, and can be used in peat and coal briquette factories equipped with belt presses to load finished products into bins of mechanized warehouses. A device for loading a hopper with articles, mainly briquettes, is known. containing a fixed guide chute, a feeding chute with curved loading and unloading ends, mounted on a rotary sector mounted on a brace and located above the loading tip of the feeding chute with two rollers covering the feeding chute and pressure mechanism 1. However, when pushing the briquette tape through the channel of the tray due to its curvature, the briquette tape is pressed against the elastic guide wall, and more specifically to the steel plate, as a result of which large forces arise and the work of pushing turns mainly into heat, which heats the walls of the channel of the tray, briquettes, and partly goes to wear of the briquettes and walls of the tray and, especially, the steel plate. A disadvantage of the known device is that the fixed guide tray and the rotary tray are fixed on different brackets, which does not allow for securely joining the movable connection of the trays and, accordingly, due to the eccentricity of the connection, the crumbling of the briquettes and the device breakage. The purpose of the invention is to increase the reliability and durability of the device by reducing the resistance to pushing through the briquettes. The goal is achieved by the fact that, in a device for loading a hopper, products, mainly briquettes, containing a fixed tray, a feeding tray with loading and unloading ends curved in an arc, fixed on a rotary sector mounted on the arm and located above the loading end of the feeding tray with the possibility of movement with respect to him, the guide c. two leading rows of rollers covering the feed tray, and a push mechanism that guides includes plates hinged with each other with side walls on which pins are fixed, with rollers of one row fixed on side walls along an arc that concentrates the bend of the loading end the feed tray and the rollers of a different row are fixed on the pins with the possibility of interaction with the bottom of the feed tray, while the side walls of the first one are rigidly connected to the bracket in the course of feeding the products. Fixed tray, it is advisable to firmly secure on the bracket. FIG. 1 schematically shows the proposed device, placed in the warehouse of finished products, the general view; in fig. 2 — node I in FIG. one; in fig. 3 - node II in FIG. 2; in fig. 4 shows section A-A in FIG. 2; in fig. 5 is a section BB in FIG. 3; in fig. 6 is a section on BB in FIG. 3. A device for loading bins consists of a fixed tray 1 rigidly fixed on the arm 2, a rotary sector 3 with a counterweight 4, pivotally mounted on the arm 2, the feed tray 5 consisting of the b-shaped end of the curved end b fixed to the sector 3, the straight part of the tray 7 and the curved discharge end 8 on which the pressure mechanism 9 is mounted, made in the form of a leaf spring. A flexible guide is located above the open curved end 6 of the rotary tray 5. Made in the form of plates 10 pivotally interconnected by sleeves 11. Flexible bending with one end rigidly attached to the bracket 2, the side walls 12 of the plates 10 are connected by beams 13, and pins 14 attached to the bottom of the plates 12. On the pins 14 are hinged the lower rollers 15 are mounted. To the upper part of the plates 12, the upper rollers 1b are hinged and mounted along an arc concentric to the open curved end 6 of the feed tray 5. The plates 10 are mounted so that they can move along the bottom of the feed tray 5. The device works yuschim manner. With empty bins, the feed tray 5 is lowered. Under the action of the forming force, the briquette tape is moved along the curved end 6 open at the top of the tray 5, while the briquette tape is pressed to the upper rollers 16 of the flexible guide plate 10. The force of pressing through the lower roller 15 is transferred to the metal construction of tray 5, and the briquette tape rolls over the upper rollers 16. The lamellar spring of the pressing mechanism 9 provides pressing force to the tray of briquette lanty, which prevents it from falling out of the tray. As soon as the pile of briquettes reaches the discharge end 8 of tray 5, the briquette tape in the tray begins to lift it, resting against the pile of briquettes. At the same time, the sector 3 with the swivel tray 5 rigidly connected to it begins to rotate on the axis 17 of Kronschtein 2. The tray as it enters the groove formed by the brackets and rollers of the plates 10, covering it in the transverse direction, first with its open curved end 6, then my part of tray 7.

When emptying the hoppers, the feed tray 5 is lowered and the filling cycle is repeated. If it is necessary to fill the adjacent bunker, a switch mechanism of a briquette tape (not shown) is provided for moving it to the adjacent bunker. A switching mechanism is installed in front of the fixed tray 1.

The proposed device due to the implementation of a flexible guide in the form of plates hinged together, reliably in the operation of the feed tray with a curved open end of the greater curvature, i.e. with a small radius, and rigid mounting of the fixed tray and feed tray on one bracket allows implement a reliable docking of the movable joint of these trays, which eliminates the breakage of the briquettes and the device.
