ji ... ill iiiji ji I Of & retony refers to the pipelines for the water transport of bulk materials JIOB, namely, the device dp supply of bulk materials, and can be used when the concrete mix is fed through a vertical pipe. (A device for feeding through a vertical pipeline is known, which contains a tank and a vertical connection with upper and lower valves and an upper level sensor Cl. With this device it is not possible to psdach, for example, concrete mix at a given speed, which causes premature wear and It is known a device for feeding bulk materials, containing a container with a vertical branch pipe mounted in its lower part for unloading material installed in the lower part of a vertical Drive valve and sensors of the upper and lower levels of the material in the vertical pipe connected to the bottom valve actuator The known device cannot transport the concrete mix to a monolithic mass, since in this case the cement mortar and solid filler of the concrete mass will separate. : The purpose of the invention is to expand the range of materials to be transported. This goal is achieved by the fact that the device for feeding bulk materials containing a container with a bottom mounted A vertical pipe for unloading the material, mounted in the lower part of the vertical pipe, the drive valve, as well as sensors for the upper and lower levels of the material in the vertical pipe connected to the valve drive, are equipped with a drive valve installed in the full section of the vertical pipe, and a vibrator, fixed to its wall, the actuator of the upper valve being associated with. sensors of both levels, and the vibrator - with a sensor of the lower level, located at the level of the lower valve. The drawing shows a diagram of the device. The device contains a container 1, a vertical pipe 2 for unloading material from the tank 1, installed in its lower part. At the outlet of the tank 1, the upper valve 3 is installed, and at the outlet of the socket 2 - the lower valve 4, Valves 3 and 4 are equipped with actuators 5 and 6, which are made electromagnetic. A vibrator 7 is mounted on nozzle 2. The device is equipped with sensors 8 and 9 of the upper levels of material in nozzle 2. Sensor 8 is installed at valve 4 level. Both sensors 8 and 9 are connected to drives 5 and 6, and vibrator 7 with sensor 8 of lower level The device has a relay 11, to which sensor 8 is connected via amplifier 12, and relay 13, which is connected to sensor 9 through amplifier 14 and thyristor 15, the nozzle is connected to transport pipeline 16 via vibration damping strip 10. The device operates as follows. When the concrete mixture enters from the tank 1 through the normally open top valve 3 to the socket 2, it is delayed by the normally closed bottom valve 4. Sensor 8, detecting the presence of concrete in the socket 2, sends a signal through amplifier 12 to relay 11, which closes contacts 11.1, 11.2, 11.3, turns on the vibrator 7 and prepares the power supply circuits of the drive 6 and the relay 13, respectively. With the accumulation of the concrete mass in the pipe-. ke 2 under the action of the vibrator 7, it is compacted and the cross-section of the nozzle is completely filled. When the height of the monolithic concrete mass reaches a given level of the upper sensor 9, the latter sends a signal through the amplifier 14 to the thyristor 15, which turns on the relay 13, which closes the contacts 13.1, 13.2, 13.3. Actuators 5 and 6 are turned on, one of which opens the lower one and the other closes the upper valves. The flow of concrete into the nozzle 2 is stopped, and the monomer column of the concrete mixture moves under the force of gravity downwards and enters the transport pipeline 16. Sensor 8, detecting the absence of concrete in nozzle 2, closes the thyristor 15. At the same time, relay 13 remains on 13.3. After full passage of concrete through the bottom valve. 4, the sensor 8 sends a signal to turn off the relay 11, which provides the disconnection of the relay 13, the vibrator 7 and the drive 6, and the relay 13 turns off the drive 5. The switches 3 and 4 return to their original position. Then the cycle is repeated.

The distance between sensors 8 and 9 is selected by the formula
