Description

one

The invention can find application in the building materials industry.

Known chamber feeders for the supply of concrete mixture containing a sealed chamber with a locking device and located in the lower part of the adapter to the concrete line, the compressed air supply system and a device for the elimination of concrete plugs.

The purpose of the invention is to increase the case rate in the operation of the chamber feeder.

This is achieved by the fact that the adapted to eliminate the concrete plug is made in the form of a needle mounted on the shock absorbers, one part of which is inserted through the compressed air supply system into the adapter and at the beginning of the concrete bushing, and the opposite one interacts with the vibrodrive.

FIG. 1 shows a chamber feeder, a view; in fig. 2 - transitional part of the chamber feeder, longitudinal section.

The chamber feeder consists of a hermetic chamber Y with a locking device 2 and an adapter 3 located in the lower lower part to a concrete outlet 4j of the compressed air supply system 5 and a device for removing a concrete plug made in the form of a needle 7 mounted on shock absorbers 6, one part of which is inserted through the system 5 of compressed air supply to the adapter 5 and the beginning of the concrete pipe

, and the opposite - interacts with the vibrodrive 8 Directional action.

Works chamber feeder as follows. After the concrete mixture is loaded with the chamber / is closed with a locking device 2 and then compressed air is added, which, by raising the pressure, displaces the concrete mixture into the concrete outlet 4. Moving along adapter 3 to the concrete conduit 4, the concrete mixture is compressed and sealed, which periodically causes the formation of traffic jams, for the destruction of which a vibro drive 8 is switched on, transmitting vibrations to the needle 7. Thus, the process of transporting the concrete mix occurs continuously.

Subject invention

A chamber feeder for the delivery of a concrete mix containing a hermetic chamber with a sprung device and an adapter for the concrete line located in the lower part of the pipeline, an air supply system for slag air and a device for the elimination of the concrete plug, which is designed to eliminate the concrete block made in the form of a needle mounted on shock absorbers, one part of which

introduced through the compressed air supply system to the adapter and to the top of the concrete pipe; and the opposite - interacts with the vibration drive.
