FIELD: equipment for making building materials, namely manufacture of laminate concrete blocks.
SUBSTANCE: line includes hoppers for sand and for cement, reservoirs for water and for surface active matters with metering devices, mixer, station for preparing mixture, branches of roller table on which according to manufacturing order are arranged: vibrating table with hoppers of charging station, heat chamber, forms for blocks, pressing down mechanism, mechanism for moving forms, station for removing forms, station for preparing mortar. Mixer is provided with rotary discharging trough engaging with hoppers of charging station by means of suspended, moved and tilted buckets. Line is in the form of two (embracing and embraced) П-shaped loops of roller tables whose free ends are mutually joined by means of single cross portion; said loops are arranged in carcass-structure framework. Cross roller-table portion of embraced loop and said single cross portion of roller table are provided with carriages moved by means of ropes of reversing winches. Upper supporting surface of rollers of carriages and upper supporting surface of rollers of roller-table lengthwise portions are arranged in the same level. Charging station of roller- table loop is in the form of vibrating table and it is mounted in separate framework. Form has large number of cells. Each cell has embedded bottom. There is gap between walls of cells. Form is mounted on platform whose base is provided with cross and cantilever arms along the whole perimeter. Platform moves on vibrating table by means of step mechanism in the form of self -aligned lug engaged with crosspieces. Said lug is jointly mounted in holder and it is coupled with rod of pneumatic cylinder. Pressing down mechanism includes folded stems of stoppers engaged with said arms. One end of stopper is jointly mounted in framework and its other end is jointly coupled with balance beam engaging with pneumatic cylinder. Charging hoppers are mounted over vibrating table along distance no less than width of platform. Each charging hopper has two discharging windows. Each cell of platform has mark on end side along its symmetry axis. Mechanisms for moving platforms on lengthwise portions of roller-table loops and on cross portion of embracing loop are in the form pneumatic cylinders. Frameworks of embracing loop, lengthwise portions, embraced loop and single cross portion have struts with H-type cross section. Said struts are designed for placing sealed heat-insulation members forming together with ends of rods tube-chamber engaged with heater.
EFFECT: improved construction of manufacturing line.
