Abstract

FIELD OF THE INVENTION The invention relates to handling. The purpose of the invention is to increase the reliability of work. The device comprises a hopper 2 fixed on the support frame 1 and a chamber 7 located under it with a spring-loaded valve 8, covered by a funnel 5, moving from a drive in a vertical direction, spring loaded 9, kinematically connected to the gate 4 of the hopper 2. The funnel 5 has the ability to interact in its upper position with a thrust of 9, and in its lower position with a valve 8. 2 Il.

The invention relates to devices for handling materials, in particular to loading stations of pneumatic conveying container installations.

The purpose of the invention is the reliability of work.

FIG. 1 shows the device at the moment of filling the receiving chamber; in fig. 2 - the same at the moment of loading the dose into the container.

The device contains mounted on the support frame 1 hopper 2 with a divider 3 stream. In the lower part of the bunker in its discharge opening there is a sector shutter 4, which opens and closes its outlet opening. Below the hopper 2 is a funnel 5, which directs the material into the container 6 to be loaded. Between the hopper 2 and the funnel 5 on the support frame 1 a receiving chamber 7 is installed with a spring-loaded valve 8 The device is also equipped with a pull 9 installed on the support frame 1 in the vertical guides 10 with the possibility of limited movement in them. The sector gate 4, which overlaps the opening of the bunker 2, is kinematically connected with the pull 9. This link is a lever 11 fixed on the gate 4 with a roller 12 at its end placed in the notch of the carrier 13 fixed on 9. The ha 9 is spring-loaded by means of the spring 14. The funnel 5, which guides the material into the container 6, covers the outlet opening of the chamber 7. The funnel 5 is hinged to the frame 1 by means of frames 15, forming a parallelogram suspension. On the funnel 5, the stops 16 and 17, as well as the seal 18, which interacts when loading the container with the neck of the latter and prevents from drinking, are strengthened. The vertical movement of the funnel 5 is carried out from the actuator 19 mounted on the frame 1 by means of a parallelogram suspension.

The device works as follows.

In the initial position shown in FIG. 1, the sector gate 4 of the hopper is open, the chamber 8 of the chamber 7 is closed (by means of the spring 14) and it is filled with material. The volume of the dose of material to be loaded-in the container

6 (without overflowing the latter), is formed by the walls of the dosing chamber 7, the valve 8 and the planes of repose of the dosing material from the edges of the opening of the hopper 2 to the walls of the chamber 7.

After the dose has been formed, the actuator 19 is turned on and the funnel 5 moves to the lower position, at which its discharge port enters the mouth of the container 6, and the seal 18 seals it (due to the parallelogram suspension, the funnel 5 retains its vertical position during the descent process). At the beginning of the lowering of the funnel, 5 tons of hectares 9 under the action of the spring 14 moves downwards and the carrier 13 acts on the beam 11 with the roller 12 of the sector shutter 4, which closes and cuts off the dose of material. When lowering the funnel 5, the stop 16 moves away from the gland 9. After the lowering of the funnel 5, when its outlet nozzle enters the mouth of the container 6, the stop 17 of the funnel 5 acts on the valve 8 of the chamber 7. The spring 20 compresses, the valve 8 opens, the release material from chambers 7 through the funnel 5 into the container 6. When the loading of the container 6 is completed, the actuator 19 is switched to lifting, the funnel 5 rises, the valve 8 is released from the stop 17 and closes the chamber 7 under the action of the spring 20. Gu 9, which with The volume moves upwards in the guides 10, compressing the spring 14 and acting with the carrier 13 on the lever 11 with the roller 12, the shutter 4 is opened and the material from the hopper 2 refills the chamber 7.
