Definitions

  • the invention relates to a device for manufacturing bricks from clay, comprising a pressure nozzle connecting onto a supply holder for forming a continuous strand of clay, a cutting member for regularly severing a piece of clay from the moving strand, means arranged close to the pressure nozzle for covering the strand with sand and means for transporting away a piece of clay severed from the strand.
  • a difficulty in applying the known device is that, subject to the composition of the clay, a tendency may occur toward premature, spontaneous breakage of the strand. That is, before the cutting member severs a piece of strand to the desired length, it has already broken off.
  • the invention has for its object to provide a solution to this problem.
  • the funnel-like part preferably has a diameter tapering from 150 to 140 mm.
  • a strand 2 is formed from a supply holder 1 for clay using a pressure nozzle.
  • the side periphery of the strand is covered with sand from a supply container 3 for sand.
  • the strand runs between a pair of rollers 4.
  • a piece is severed from the strand to the desired length.
  • the severed piece 6 is subjected by a pair of conveyor belts 7 to an accelerating movement such that the block 6 falls with high kinetic energy into a mould container 8 and fills it.
  • sand-covering is carried out by spoon-like members 9, 10 which carry sand out of the supply container 3 onto the side wall of the strand.
  • a funnel-like part 11 is arranged connecting on the pressure nozzle opening, the diameter of which part 11 has a comparatively small taper in the vertical direction.
  • the taper is preferably from 150 mm to 140 mm. Practical experience has shown that the danger of premature breakage of the strand is obviated with the present step.
