Abstract

The invention relates to devices for alternately unloading from several bins with one drive mechanism, alternately interacting with their closures. The purpose of the invention is to increase the reliability of work. A bunker device containing successively placed hoppers 1 with outlet openings 2 and discharge chutes 3 fixed under them, each of which is equipped with a finger lock (PZ) composed of several fingers sequentially mounted on the axis 7, is equipped with a PZ drive. The drive PZ is made in the form of a carriage (K) 15 with a profiled groove 22 for engaging with the rollers 10 of the levers 8 rigidly connected to the axis of the PZ. at the same time, K 15 is mounted on guides 14 with the possibility of reciprocating movement by means of a winch 27 with a drive and a cable-blocking system. The device is equipped with a PZ control system with limit switches 32 connected to the drive chain of the winch 27, and a stop 23 is installed on the K 15 to interact with the limit switches 32. 1Cp. f-ly. 7 il.

Description

The invention relates to the storage and distribution of bulk materials from bunkers, in particular fuel briquettes, and can be used in peat and coal briquette factories, in construction and other sectors of the national economy.

The purpose of the invention is to increase the reliability of work.

The bunker device contains successively placed on the supports of the bunker 1 with outlet openings 2, under which the discharge chutes 3 are fixed. Above each tray in bearings 4, supported on its side walls, an axis 5 is installed. On which, by means of sleeves 6, a finger gate formed of the fingers 7 fixed on these bushings. Each axis 5 is rigidly connected to the lever 8, on the free end of which a roller 10 is mounted using the axis 9. In the walls of the sleeves 6 are pie slits 11, and the axes 5 are fitted with fixed on their radial pins 12, the number of co (

This corresponds to the number of fingers installed with the ability to interact with the sector slits 11. Guides 1 with brackets 13 hang guides 14, made up of individual I-beams, on which a carriage 15 is mounted, supported on the inner flanges of the I-beam with running rollers 16, mounted on the axes 17. The vertical movement of the carriage 15 is limited by the thrust rollers 18 mounted on the axes 19. The axes 17 and 19 are mounted on the sidewalls 20 of the carriage body, between which the bushes 21 are fixed a flap, a profiled groove of 22 days of interaction with the rollers 10 of the levers 8, having two inclined, symmetrically arranged and radially defined portion, and a lower horizontal portion with a depression in the middle part. A stop 23 is mounted on one of the sidewalls 20 of the carriage body. To the opposite sides of the carriage body 15, a cable 24 is secured, which is stored in tension blocks 25 mounted on the ends of the guides 14 and several times around the drum of the friction train 25 of the winch 27 of the cable block system. The drum 26 is mounted on the low-speed shaft of the gearbox 28, kinematically connected to an electric motor 29 equipped with an electromagnetic brake 30. The upper branch of the cable 24 is passed through the guide nozzles 31 of the brackets 13 mounted on the guides 14. In the areas of interaction of the profiled groove 22 with the rollers 10 levers 8, as well as at the beginning and at the end of the working stroke of the carriage 15, limit switches 32 are installed on the guides 14 with two-arm contact angle levers 33 with rollers. The limit switches 32 are included in the control circuit of the electric motor 29 for the drive of the winch 27.

The device works as follows.

Before starting the unloading cycle, the unloading of bulk material, such as peat or coal briquettes, located in the bins 1 and filling trays 3, is prevented by finger closures, the fingers 7 of which, under the action of their own weight, are in the closed position, touching their ends with the bottoms corresponding trays. In this case, the levers 8, provided with rollers 10, occupy the extreme upper position, and the carriage 15 is located, for example, on the right, at the beginning of the guides 14, between the first of the consecutive bins and the two extreme limit switches 32, by pressing the start button on the control panel electric motor 29 for driving winch 27, whose rotation through gearbox 28 is transmitted to friction drum 26, re-winding cable 24 several times around it, and informs carriage 15 fixed to its ends and moving forward to left. The carriage 15 moves along the guides 14, resting on its inner shelves with the rollers 16, and

5, as the carriage 15 moves further, this section of its profiled guide will act on the roller 10, and through it on the lever 8, turn the latter counterclockwise and bring it to the extreme

The 5 sector slits 11 in the walls of the sleeves 6 rotate and simultaneously lift the fingers 7 fixed on these sleeves to the Open position. Upon further movement of the carriage 15 roller 8 enters

5, the carriage 15 is stopped. A hollow in the horizontal section of the profiled groove 22 prevents (at the time of stopping the motor) the movement of the roller 10 to its opposite section

sequence by acting on the roller 10 of the lever 8, first with a horizontal section with a depression, and then with an inclined radius 22 opposite the radially outlined radius 22. The impact on the roller 10 with this inclined section is accompanied by turning the lever 8 counterclockwise and lowering all the fingers 7 of the shutter into Closed position. Since the rotation of the lever 8 occurs without loss of the contact of the roller 10 with the spline-drilled groove 22 and with the constant interaction of the pins 12 with the sector slits of 11 bushings 6 - the shutter fingers 7 are moved to the Closed position smoothly and without hitting the bottom of the tray 3 At the same time, the possibility of a piece of material falling under any of these fingers does not prevent the installation of the rest and the Closed position. The following 15 bins 1 are emptied in the course of movement of the ko-net. On the path of the subsequent movement of the carriage 15 (after emptying the outermost during the movement of the bunker), the stop 23 interacts with the limit switch 32 installed at the end of the carriage travel, after which it stops in the leftmost position. In the event of a possible malfunction of this final switch, a similar duplicate is installed next to it. The repeated unloading cycle is carried out in the described sequence when the carriage 15 is moved to the extreme right position due to the reverse

motor 29. In this case, the anvil 23 of the carriage 15 will engage in series with the rollers of the two-arm contact angle levers 33 that were installed in the previous cycle below the level of the upper flange of the guides 14.
