Description

 The invention relates to the production of building materials, in particular to the production of bricks.

 The known design of the machine for cutting clay bar SMK-678A, containing a conveyor, a slide, a bow with a string and a drive for turning it (Ilyevich A.P. Machines and equipment for factories for the production of ceramics and refractories. M., Higher School. 1979, p. 217-219, Fig. 122).

 The disadvantage of this machine is the inability to obtain a contoured surface on the bed plane of the brick for increased adhesion of the brickwork.

 The technical solution closest to the claimed one and adopted as a prototype is an earthenware cutter containing a conveyor, a drive, a slide, a beam with a string and punches with grooves mounted on the beam using arcuate holders (application for invention 2000123229/20 M. class. (6) B 28 V 11/14 "Automatic machine for cutting clay beams"). This machine allows you to get a contoured surface on the bed plane of the brick, increasing the adhesion of the brickwork.

 The disadvantage of this machine is the complexity of the beam design due to the use of arched holders concentric to the rotary shaft.

 The problem solved by the proposed technical solution is to simplify the design of the mechanism for cutting clay beams intended for the production of bricks with a shaped surface of the bed plane, providing increased adhesion of the brickwork and thereby increasing its strength, seismic resistance and other indicators.

 The problem is solved due to the fact that to increase the surface area of the bed plane in the proposed device, the slotting agents are mounted on a string that cuts a clay beam, and are made either in the form of a continuous spiral wound on a string, or in the form of short spirals with a mustache / type of barbed wire /, or other similar elements fixed to the string.

 When cutting a beam, a string with such elements creates in the cutting plane / for a brick it is a bed / either a wavy surface / if the grooving agent is a continuous spiral / or transverse grooves of various depths that increase the adhesion surface of the brick with the mortar when masonry is performed.

 The manufacture of spirals is simpler and more technologically advanced than the manufacture of punches and arched concentric to the rotary shaft of the punches.

 An example of a clay beam cutting mechanism using the proposed technical solution is shown schematically in the drawings, in which Fig. 1 shows a view of a mechanism c from the end face of a clay bar facing cutting, in Fig. 2 is a top view — along arrow A in FIG. 1, and FIG. 3 separately shows a string with grooves made in the form of shortened spirals with a mustache / on an enlarged scale /.

 The clay beam cutting mechanism comprises a conveyor 1 and a drive 2 with a movable sleeve 3 kinematically connected to the conveyor 1. A frame 5 with a string 6 is mounted on a rotary shaft 4 placed in the sleeve 3, and the slide 7 is mounted on the sleeve 3. On the string 6 grooving agents are installed — either one continuous spiral 9 wound on a string 6 with a mustache 10, similar to spirals on a barbed wire / 3 /.

 The mechanism works as follows. The conveyor 1 receives movement from the clay beam 11 exiting the extrusion press / not shown /, and through the wire 2 reports the reciprocating movement of the sleeve 3 with the slide 7, the shaft 4 and the beam 5. If the direction of movement of the beam 11 and the sleeve 3 coincides by turning the shaft 4 frame 5 is lowered onto the beam 11 and the string 6 cuts raw brick from it. In this case, the grooving agents / for example, the coils of the spiral 8 / leave on the cutting planes, that is, on the bed surfaces of the brick, a large number of mini-grooves that increase the area on the bed surfaces of the brick and thereby increase the adhesion of the brickwork.

 When using shortened spirals 9 with a mustache 10 as shown in FIG. 3, the number of mini-grooves will be smaller, but their depth is greater, which also increases the area of the bed surfaces of the brick and increases the adhesion of the brickwork.
