Claims (2)

Both carriages are installed, the cutting knife is made with a saw-tooth edge on the pepper end upright and with a groove opposite to it, in which the pressure rollers in contact with the cutting head and the knife are located on the front edge of the damper knife, as well as that the prigruyechny plate is equipped with triangular fasco-formers and a pair of parallel ribs, which it is connected to with a frame and made with a long slit along which the formers are located, with the side walls of the casing Holes with retainers placed in them, and the knife of the pacifier are equipped with brackets and adjustable, fixed to the loading plate. This technical solution allows to perform a cyclic (from top to bottom on the depth of the layer of concrete) cutting with both knives, and to put them into concrete cut, horizontally continuous seam. .-, .-,. FIG. 1 shows the device before it is buried in concrete, general view; in fig. 2 - the same, after deepening knives in concrete; in fig. 2a shows a section A-A in FIG. 2; in fig. 3 is a section bb of FIG. 1; in fig. 4 - uzep 1 ya fig 3}. in fig. 5 shows a section B-B in FIG. 1;. FIG. 6 - cutting knife, type of sat; eye ;; n and fig. 7 - cutting knife, view in FIG. 8 - soothing knife, side view; in fig. 0 - soothing knife, front view; in fig. 10 — loading plate, vic sideways in FIG. 11 is a sectional view in FIG. ten; on fig 12 is a view along arrow D in FIG. 1 p. The self-propelled chassis 1 is equipped with a device for continuous cutting of the temperature weld, consisting of frame 2, loading plate 3, cutting knife 4, soothing nick 5, main water carriage 6, additional carriage 7 and pressure rollers 8. 1 sawtooth cutting edge 9 and lower cutting edge 10. Sedation knife has a sickle shape and bottom edge 11, in: also elastic membrane 12. The front part 13 of the soothing knife enters the slot 14 of the cutting knife with a gap. The loading plate is equipped with triangular phosphate formers 15 and parallel bars 16,. by means of which it is connected with frame 2, and made with a longitudinal slit 17, along which the specified formers are placed. Holes 18 are formed on the side walls of the casing made by the carrier, in which clamps 19 are placed, and the knife of the pacifier is provided with two brackets 20 adjustable by rod rods 21 fixed to the loading plate 3.N Device for continuous cutting of the temperature weld in freshly smoked concrete works as follows. After installing the self-propelled chassis 1 with the device along the marked line of the seam being cut, the cutting knife 4 and the soothing knife 5 are raised by feeding the hydraulic cylinders, and the fixers 19 holding the blades in the transport state sink into: the holes 18 on the walls of the housing. Under the action of the mass of the vibration blade and the loading plate 3, the knives are lowered by the lower edges 10 and 11 with the loading feeder 3 on the pin of the cut seam. Then the nibrators of the knives 4 and 5 are turned on. When the knives are etrm, they are loaded into the concrete by the action of their own weight and vibration forces. When the knives reach the required depth. The vibrator of the pacifying knife 5 is turned off when the stroke is simultaneously engaged. In front of the self-propelled chassis 1, during movements of which the front cutting edge 9 of the knife 4 forms a seam with a width equal to the thickness of the knife. For a knife with a gap, it is a successful knife 5. Its elastic membrane 12 dampens vibrations and aligns the walls of the seam, and the loading plate 3 and the tongs 15 align and form the edges of the grooves. The gap between the blades allows you to eliminate the transmission of vibration from the cutting knife 4 to the soothing knife 5. The pressure rollers 8 are tightly pressed against both planes of the knives 4 and 5 and do not allow them to go out of the same plane. After cutting the seam to the required and depth, the knives are lifted using lifting devices, for example in the form of hydraulic cylinders, to the upper extreme position with simultaneous lifting of the loading plate. After cyclic cutting of the seam, instead of an additional carriage 7, you can install a tool for inserting a filler, for example, a plastic film, pipe, cable, etc. into the cutting seam. The cutting knife has front and lower cutting edges, and the cutting knife has a lower cutting edge Narrow seam as cyclically (from top to bottom) so ir continuously (with horizontal cutting of the cutting organ), i. The present invention allows for cutting seams in svezheuluzhenny concrete to a greater depth (approximately 1 meter) to introduce industrialization, which will significantly reduce labor costs, consumption of materials and the duration of cutting seams. Claim 1. Device for continuous cutting of a temperature weld in freshly laid concrete, mainly when building an armature gnosistechnical structures, containing an additional frame, a drive carriage, on the supporting platform of which the inserter is mounted into the cutting knife with a lower cutting edge, a load plate and a slip plate with an elastic membrane This is so because, in order to increase the efficiency and increase the depth of the weld seam when layering the concrete bed {and, the device is equipped with an additional drive carriage with vibrates With a bore, on the supporting platform of which, a damper shaped like a crescent-shaped knife, covering the elastic membrane, is mounted, with a casing having pressure rollers and vertical guides, in which both carriages are installed, the cutting knife is made with a saw-tooth edge on the front vertical end and with a groove The opposite, in which the front edge of the knife is placed, and along which the pressure rollers are in contact with the cutting knife and the knife. 2. A device according to claim 1, characterized in that the loading plate is provided with triangular face shapes and parallel bars, by means of which it is connected to the frame and made with a longitudinal slit along which the face formers are placed, and the side casing sides have an aperture with retainers placed in them, and the knife of the pacifier is provided with brackets and adjustable arms attached to the loading plate.
