The goal is to increase the efficiency of the machine with a different filling material with different physical properties. The machine consists of ca-, measures 2 and 3 with valves 8.9, 10, loading pipe (TP) 11, air supply TP 17 and transport TP 18. At the same time TP 11 is made in the lower part with openings 21 and is equipped with adjustable gate 25 and a sealed chute 22. The perforated wall of the TP 11 and the chute 22 form with respect to the TP f 7 a cadreted and sub-perforated cavity. The area of the passage section of the TP 17 is equal to the sum of the areas of the passage sections of the over- and sub-perforated cavities, and the area of the passage section of the perforated cavity is equal to the area of the passage section of the TP 18. The inequality of perforated cavity, the sum of the areas of the holes 21 and the perforated cavity. Loading material is loaded through the receiving device 1 into chambers 2 or 3. From chamber 1 through the shutter 10, the filling material is fed to a vibrating load full-time TP 11. The compressed air supplied from TP 11 blows the filling material into TP 18. At the same time, the compressed air enters directly into the supraperforated cavity and into the sub-perforated cavity.

Description

The invention relates to the mining industry and can be used in backfilling operations during the development of mineral deposits.

The aim of the invention is to increase the efficiency of a machine with a different filling material in terms of physical properties.

among themselves and have boot 4.5 and unloading 6.7 windows. The latter are provided with valves 8, 9, 10. The loading pipe 11 is rigidly connected to the vibration actuator 12 and is located in the hermetic cavity 13 formed by the lower part of the chambers 2 and 3 and the base 14, which are rigidly connected between

themselves and connected by elastic diaphragms 15 and 16 with the pipeline 1t. The air supply pipe M and the transport pipeline 18 are elastically connected to the flanges 19 and 20 of the loading pipe 11 in the lower surface of which there are openings 21z and a sealed chute 22 is connected. The pipe 11 has inclined trays 23 and the operation regulator 24 of the slide gate 25. Regulation is performed by pneumatics band 26, openings of the gate 27 and -russ 28 Regulator 24 is isolated from the cavity 13 by a sealed diaphragm 29

The machine operates as follows. The stowage material comes from the reception of the inspection device 1 in portions through the chambers and 3. When the shutter 8 is open, the next portion of material enters through the loading window 4 into chamber 2, the shutter 8 opens and the transport pressure is set in chamber 2 pipe 18. After that, the shutter 10 of the discharge port 6 is opened and the backfilling material is dumped onto the inclined trays

When the regulator gate 25 is open

A 24 compressed air stream flows from the air supply pipe 17 through the openings of the gate 27 to the loading pipe 11 and through the hermetic chute 22 through the holes of the perforations 21 to the loading pipe 11. From the latter, the filling material is carried to the transport pipe 18.

In this case, the mode of transportation for dry bulk materials is carried out. When the gate 25 of the regulator 24 is closed, a jet of compressed air flows from the air supply pipe ™ of the duct 17 through the holes of the gate 27 through a sealed chute 22 through the holes in the perforations 21 into the loading pipe 11. The stuck stowing material separates from the bottom surface of the loading pipe

Yes 11 and is carried away to the transport pipeline 18. In this case, the mode of operation is carried out - blowing the bottom surface of the loading pipe for wet viscous materials

The required ratio of the flow area of the airflow of the perforated cavity to the area of the flow area of the perforated cavity of the loading pipeline is established depending on the physicomechanical properties of the transported material. A certain backfill material corresponds to a certain position of the gate 25 with an opening 27. In this case, a stream of compressed air enters from the air supply pipe 17 through the openings of the gate 27 to the loading pipe 11 and through the sealed chute 22 through the holes in the perforations 21 to the loading pipe 11. This ensures tearing off the sticking material on the bottom surface of the loading pipe 11 and transporting it to the transport pipeline 18. A rational condition for the operation of the machine is the condition when the flow area of the air supply pipe 17 is equal to the sum of the flow areas of the overperforated and sub-perforated cavities of the loading pipe 11, and the flow area of the transport pipeline 18 is equal to the area of the flow area of the perforated cavity. It also requires compliance with unequal
