Description

one

The invention relates to conveyor installations for the manufacture of products from concrete masses by the method of vibropressing, for example, paving slabs, etc. and can be used in the building materials industry,

A known conveyor system for the manufacture of concrete mass products containing a frame, an endless conveyor with a side rig and drive for its movement and accommodated in a technological equipment sequence consisting of a hopper with metering devices, a vibropress mechanism, an ejection mechanism and a stack of finished products and devices for cleaning and lubrication of air equipment I.

A disadvantage of the known conveyor installation is that the vibration oscillations from the operation of the vibropressing mechanism are transmitted through the frame to many working elements of the installation, which under the influence of the vibration oscillations quickly go out of order,

The purpose of the invention is to increase the service life of the working bodies of the installation.

This goal is achieved by the fact that the frame at the top of the conveyor

at the place of vibropressing, it is made split and isolated from the boarding equipment, the boarding equipment and the vibropressing mechanism are provided with locking devices, each of which is made in the form of an eyelet with a hole on the longitudinal side of the boss and the stop; fixed movably on the vibropressing mechanism,

FIG. 1 shows the proposed installation; in fig. 2 - the same, plan view; in fig. 3 - section A-A of FIG. one; in fig. 4 - section bb FIG. one; in fig. 5 - the same, side view.

The installation includes a frame 1, on which the conveyor moves with sealed 4I forms consisting of airborne equipment 2 and a pallet 3, the airborne equipment is connected by hinged links 4, a movable hopper with dispensers 5, shaken by a crank-connecting rod mechanism 6, a vibropress mechanism 7 vibration exciter 8, a mechanism for pushing out freshly molded products 9, a mechanism for stacking these products with a cassette drive 10, a mechanism for moving forms 11 with a hydraulic system 12.

3 half-full molds of the molds are made holes 13 for ejecting the cook: products. The stops 14 of the mechanism for moving 11 forms with eyelets 15 and which have holes for fixing the form at the vibropressing station 7,

On the rear wall of the conveyor mouth (Iovlen cleaning mechanism and lubrication 16 and 17.

The vibrating mechanism 7 is fixed on the foundation with the help of elastic elements 18 and 19 and the bolted coefficients 20.

The vibration damping mechanism contains a vibration table 21 with an exciter 8, movable stops 22, sliding in guide sleeves 23, valve 22 with an emphasis 25, loading plates 26 with guide rods 27,

In the traverse 24, holes are made for the direction of the thick stems of the rods 27. The pressure plates are connected to the vibrating frame 21 by the hydraulic cylinders 29, in the supply circuits of which pressure regulator 30 is installed.

The stack mechanism of the stacking mechanism 10 has stops 31,

The installation works as follows. The pallets 3 are placed into the rig 2, the transfer mechanism II by the stops 14 feeds them one step, the hopper dispenser 5 feeds the concrete mixture into the form, which is fed to the vibrating table 24p of the vibropressor mechanism 7 isolated from the frame,

Cylinder 28 moves transport 24 down, traverse support 25 presses the mold to the vibrating table 21, pre-fixing the position of the landing gear with movable lugs 22, due to lugs 16 from hole 1 w, relative to pressure plates 26,

The hydraulic cylinders 29 lower the clamping plates 26, which press the concrete mixture simultaneously with its vibration,

The regulator 30 of the pressure in the supply chain of the hydraulic cylinders 29 allows the change in the value of the specific pressure of the pressing.

The cycle of vibroforming lasts 210-4 seconds depending on the stiffness of the concrete mix.

After the vibroforming process, the mold is moved to the ejection post 9 and the freshly molded article on the pallet 4 enters the storage cassette 10,

When moving up, the tile disengages the lugs 31 of the storage cassette and lifts the stacked products in it. When the rods 9 move downward, the pallet with 1 piece rests on the stop 31,

After the storage cartridge is full, it is replaced with an empty one.

Installation works automatically.

The use of this installation allows one to automate the technological process of making concrete izleliy using the method of vi. with the weights as well as to automate the removal and laying of the molded products, and the installation design allows the use of concrete mixtures of different composition (bulk, crushed stone, silicate).
