Abstract

The invention relates to belt conveyors and can be used to average bulk material when unloading a belt conveyor. The purpose of the invention is to increase the homogeneity of the bulk material while reducing the size of the averaging device. The device includes a chassis trolley with a W-shaped groove (G) installed on it and deflecting rollers. In the end wall W there is a discharge window, in which an adjustment plate can be installed. A deflecting drum (OB) and a dumping drum (SB) are installed in the grooves W, and there is a bottom slot between the grooves W to drain the unloaded tape. Inside the OB is installed a fixed sleeve with a screw winding. Face stacks OB are made of plates, one end fixed on the axis OB, and the other on the sidewall, and rotated at an angle to the vertical plane. The SC has an external auger winding either one-sided or with two oppositely wound parts. The transported material comes from the tape lying on the OB on the SB, where it is divided into two streams either by an adjustment plate or oppositely wound parts of the SB screw, while one stream enters the IN, moves along its axis along the spiral of the fixed auger, unloads from Both are combined with the original stream with a time delay. 1 hp f-ly, 7 ill.

Description

The invention relates to belt conveyors and can be used to average bulk material when unloading a belt conveyor.

The purpose of the invention is to increase the homogeneity of the bulk material while reducing the size of the averaging device.

FIG. Figure 1 shows the averaging device, side view, section; in fig. 2 - the same, top view; in fig. 3 end wall of the deflecting drum, front view; in fig. 4 - the same, side view, cut; in fig. 5 is a diagram of the movement of bulk material in a W-shaped trough for

side-wound auger unloading drum; in fig. 6 - averaging device with a dumping bar, an auger whose screw is made of two parts with oppositely oriented windings; in fig. 7 is a diagram of the movement of the bulk material along a W-shaped chute for the case of double-sided auger winding.

The device for averaging the bulk material during unloading of conveyors includes a undercarriage 1c with wheels 2, on which in trench 3, which is W-shaped in the middle part, deflecting i and Eintechnoi dropping 5 drum are installed.

A sleeve 6 with a screw auger 7 is fixed to the channel of the channel 3. Inside the screw there passes a shaft 8 of an inclining drum which rests on bearings E mounted in the walls of the channel and closed by covers 10 and on a bearing 11 closed by a cover 12, to one end The taller 8, passing through the wall of kelob, is attached to the drive pulley 13 of a flexible belt drive. I A deflecting drum k is put on the stationary sleeve b, with one end of the end wall k supporting-: on the stationary sleeve 6 through the bearing 15. The other end wall J16 is fixed to the shaft 8. The end wall lA has loading windows 17, separated by angled angles (depending on the size and moisture of the material, the angle is 15-30) to the vertical plane plates 18. The end wall 1b has discharge windows. In the corner of the chute 3, under the loading window and the drum 5, there is a channel fenced off from the main tank of the chute by a pivoting plate 19, which is hinged by the lower edge to the bottom of the chute 3 and can be rotated in a vertical plane.

Screw dumping drum 5 has one direction of winding of the blades. The shaft 20 of the screw drum 5 rests on bearings 21 installed in the walls of the groove and covered with covers 22. One end of the shaft 20 passes through the wall of the groove and is provided with a driven pulley 23 of a flexible belt drive. The transmission of rotation is carried out by a 2k belt,

The diverting drum k bends around the conveyor belt 25. In the middle part of the chute there is a channel 2b for the passage of the conveyor belt, and on the lower surface of the chute there are inclined ki roles.

The device works as follows.

The device on the conveyor is installed at the point of discharge. The material through the deflecting drum is poured into the part of the chute in which the screw drum 5 is installed. When the screw drum 5 is rotated, the bulk material is transported to the discharge window and poured into tray 27. Part of the flow is cut off by plate 19 and part through the loading windows in the wall 1 of the drum it is poured inside the diverting drum 4 and, when rotated, it is transported along the axis of the fixed screw to the end wall 1b. Through unloading-. The windows in the end wall 1b of the material are again poured into the chute and fed to the screw drum 5, where it is mixed into the feed coming from the conveyor to the material. This operation is carried out continuously. The amount of material guided through the drum is adjusted by rotating the plate 19.

The rotation of the diverting drum t is carried out with the movement of the belt 25, and the screw dropping drum 5 from the deflecting drum through a flexible temporary transmission.

Separation of the flow of bulk material in the particular case is possible with the use of a discharge screw drum with multidirectional winding (Fig. 6). In this case, the screw drum 5 has oppositely directed winding sections 29 and 30 of the screw auger separated by a vertical plate 28, the loading windows of the deflecting drum k are reversed, the direction of winding of the spiral of the screw 7 inside the deflecting drum k is changed and there is no turntable 19 for flow separation bulk material. I,

When the conveyor on which such a device is installed, the material is pushed through the deflecting drum k into the chute 3, where, on the spiral drum 5, it is divided into two streams, one of which, when the drum 5 rotates, is fed with a screw 30 Tray 27,

and the other thread is transported by screw winding 29 to the wall of chute 3, gets into the loading windows 17 of the end wall T of the deflection drum k, with the fixed screw 7 as the drum rotates k moves along its axis and through the discharge windows of the end wall of the deflecting drum falls out of the drum to unload - a tray 27, where it is connected to the main flow of bulk material.

Thus, the proposed device allows separating the flow of bulk material with a predetermined delay of one of the two flows in the channel having the smallest dimensions.
