The invention relates to konveyerostroeniya, in particular, to devices for loading belt conveyors bulk materials.

The known device for loading belt conveyor, comprising a hopper (Spivakovsky, A. O., etc. Transporting the machine. - M.: 1968, S. 462-463, Fig. 33a).

The disadvantage of such devices is the low efficiency of the pipeline due to asymmetrical loading.

The closest in technical essence to the present invention is a device for loading belt conveyor, including ruspolia her with the possibility of vertical movement of the flap (French patent N 2225362, class B 65 G 47/19, 1974).

The material on the belt feeder is made through a gate valve which determines the flow area of the outlet, thus regulates the performance of the feeder. Because the device is installed above the working branch flat belt feeder, it contains a gate-valve straight-line profile for capacity control. From the viewpoint of the uniformity of load distribution across the width of the tape is formed in such a device profile of the material on the tape corresponding to the angle of repose of the material, is not optimal.

This means that this device may be offset center of gravity of the loaded material in the transverse plane with the axis of the conveyor belt. This, in turn, may bias the load-carrying tape with the axis of the pipeline, which ultimately leads to the low reliability of the prototype.

The invention solves the problem of increasing the reliability of operation of the device for loading the belt conveyor by ensuring optimal distribution of the load over the width of the conveyor belt, and eliminate the possibility of displacement of the conveyor belt about the, including and located over the conveyor belt hopper with the outlet on the front wall and attached to it with the possibility of vertical movement of the valve, provided with a deflector rollers installed in the area of the tailgate on both sides of the conveyor belt symmetrically relative to the axis of the conveyor, while the profile of the lower edge of the flap is made on the profile of the surface of the conveyor belt.

Comparative analysis of the essential features of the prototype and the proposed technical solution shows the presence in the latter of distinctive features, which shows the relevance of the proposed technical solutions to the criterion "novelty".

Thanks to the implementation of the distinctive features of the proposed technical solutions together with characteristics in common with the prototype, we offer you a new technical result is ensured uniform and optimal distribution of load on the conveyor belt across its width when strictly fixed position of the tape relative to the axis of the conveyor, which allows to achieve the purpose of the invention.

This technical result is not clear from known the character of the proposed technical solutions together with characteristics, in common with the prototype. This allows us to conclude that the proposed solution meets the criterion of "inventive step".

In Fig. 1 presents the proposed device; Fig. 2 is a view along arrow in Fig. 1.

The device comprises a hopper 1, the front wall 2 which has an outlet opening 3.

On the front wall 2 of the hopper 1 are also movable flap 4. The profile of the lower edge of the valve 4 corresponds to the profile of the conveyor belt 5, download the conveyed material 6. Under the conveyor belt 5 in the download area are poddanye rollers 7.

In addition, in the download area on both sides of the conveyor belt 5 is symmetrical relative to the axis (position not defined) of the conveyor belt is installed deflection rollers 8, preventing the displacement of the conveyor belt 5 with respect to an axis of the pipeline.

The front wall 2 of the hopper is installed on the hinge 9, the lower part of the wall 2 is connected with the side walls of the hopper by means of a spring shock absorbers 10.

The guides 11 are used for vertical movement of the valve 4. To improve the efficiency of the output material 6 from the hopper 1, the device is equipped by moving along the guide rails 11 mounted in the desired position, define desired performance of the device, and fix. In the process, the front wall 2 and the valve 4 are integrated.

Loaded into the hopper 1 material through the valve 4 falls onto the conveyor belt 5. Thanks to the line profiles of the tape 5 and the valve 4 is created optimal distribution of load transported material across the entire width of the tape.

When this deflection rollers 8 provide a symmetrical position of the tape 5 relative to the axis of the pipeline.

If the weight of the transported material 6 are large items, the front wall 2 with the flap 4 is deflected along the tape 5, skip the subject and under the action of the spring shock absorbers 10 is returned to its original position. Movement of the valve 3 up and down along the guide rails 11 can adjust the performance of the device.

The proposed solution can be used in construction, such as construction of hydroelectric power station.
