Abstract

The invention relates to the production of hollow concrete products. The purpose of the invention is quality improvement. products and performance. Method of making hollow concrete products - consists in installing dividers 1 on conveyor 3 and supplying them to the forming zone, feeding / concrete mix to conveyor 8, its pre-compaction, moving the mixture to the forming zone and its subsequent pressing, carried out simultaneously with vibration in the direction perpendicular to the movement of the mixture, and with vibration of the emptying formers 2 relative to the longitudinal axis. A device for making hollow concrete iz. The product contains a hopper 5, the top 8, the bottom 3 and the side conveyors, the top 8 of which is embedded with the inclined pressing section, and the bottom 3 with the leading forks 4- for supplying separators to the forming zone, hollow cores 2 and the vibrating frame 6, on which fixed the rollers of the inclined pressing section of the conveyor 8 and the rollers of the conveyor 3, located under the inclined pressing section. In this case, the pitch between the forks 4 is equal to the length of the product, and the outer surface of the holders is made along a helix. 2 sec. f-ly, 2 ill. (L

Description

cpus.1

The invention relates to the manufacture of hollow concrete products.

The purpose of the invention is to improve product quality and performance.

FIG. 1 schematically shows the proposed device, a longitudinal section; in fig. -2 - type A in FIG. one"

A device for the manufacture of polysus products contains separators I, jg forming the ends of the product and mounted on the core-forming 2, the lower conveyor 3 with the leading fork-. 4 for supplying dividers I to the forming zone, the hopper 15 5, the vibrating frame 6, the device 7 for vibrating the bust-formers 2 relative to the longitudinal axis, the upper conveyor 8 with an inclined pressing section, lateral conveyors 9, 10 20 and vibratory roller 11. Lower branch of the upper 8 and the upper branch of the lower 3 conveyors are supported by the rollers 4, and the internal branches of the conveyor belts are supported by the rollers 15. The rollers 14 and 15 are secured with the vibrating frame 6. The hollow cores 2 are fixed on the support 16 and are connected with the fixture 7, made in the form bratora. The step of installing the leading forks 4 is equal to the length 30 of product 12, and the holders 2 are made with a screw outer surface.

. The method of making hollow concrete products is carried out as follows:

3QM.

The separator 1 is brought over the waste generator 2 to the operating lower conveyor 3, which, with the aid of forks 4, picks up the separator 40 1 and moves it. Then, the pallet 3 is placed on the upper conveyor belt 3 and the second separator 1 is fed. Then the conveyor 3 moves the separators 1 and the pallet to the forming zone, after which the conveyor 3 is turned off. From the hopper 5, the mixture is fed to the forming zone, the vibrating frame 6 is simultaneously put in operation, the device 7 for vibrating the bore-formers relative to the longitudinal axis and the conveyors 3, 8, 9 and 10. Then the device works non-stop. The mixture, which is fed to the conveyor belt 9, is pre-leveled and compacted by the vibratory roller M. In the course of molding, the mixture gets into parts of conveyors 3 and 8, at the end

with a torus, their rollers are fixed on the vibration frame 6, and the mixture is pressed by the inclined pressing section of the conveyor 8 simultaneously with the vibration by means of the vibration frame b in the direction perpendicular to the mixture movement and with the vibration of the bore formers 2 relative to their longitudinal axis with the aid of 7. After shaping and exit products from vibrorams 6, it is calibrated, moving along the conveyors when vibrating the bed formers 2. The finished products 12 are moved by the roller table 13 and then separated from each other.
