Description

In the present invention, which relates to a device for cutting stones from an array using chainsaws and a strip of one form or another provided with cutting elements, chainsaws are mounted on processes of an L-shaped frame, between which a cutting strip is installed, which receives return movements,

In the schematic drawing of FIG. 1 is a perspective view of a device; FIG. 2 is a bottom view of the J-o6pa3HyjK) frame with gears, levers and a cutting strip (the frame of the frame is shown in section); FIG. 3 is a section along the ab line in FIG. 2; FIG. 4-modified device for reciprocating the cutting strip; FIG. 5-8 is a side view and in longitudinal section of two different forms of cutting elements.

The main cutting tool is a flexible rod 10 (Figs. 1 and 2) with cutting edges, placed between the processes 2 of the IT-shaped frame 1, equipped with two grippers 3, in which the drive shaft 4 with two driving gears 5 is fastened to the bearings and applied pulley 6. At the ends of the processes 2, end gears 8 are placed at the ends of the shoots 7, carrying, with the teeth 5, chains 9 with teeth. The rod 10 is attached to the ends of the shafts on axles 11 (Fig. 2) of the levers 12, the other ends of which are connected by a tag 13 with a pin 14 entering the wave-shaped groove 15 on the washer 16 placed on the drive shaft 4. When the shaft rotates 4 tons ha 13, and with it, through levers 12 and lane 10 are brought into reverse motion. The cutting edges on the strip 10 can be obtained by bending along the axis of the spiral plate with teeth on two sides or by milling. or on rollers of corresponding protrusions, followed by coating with a solid substance, or by pressing on crystals with good abrasive properties, or by sticking a corundum or diamond crystal on the rod with a subsequent electroplating of the surface, or putting a different shape on the weapon strip (Fig. 5-8) from metal, subjected to special heat treatment, or from non-highly abrasive materials. By the grippers 3, the cutting part is fixed on the diamond-shaped frames 22, rigidly fastened to each other and carrying at the other end the motor 23 with the rheostat. Frames 22 are suspended in wheelbarrows corresponding to the axis

; vada 24, to prismatic frame 25, having at its base a turning circle 26, the lower part of which is associated with two faces 27. It also has control discs 28 that can turn over zholo axis 29 by handle 30. Shaft 24 , driven by the motor 23 through the .kushk 31., has a pin groove and serves: for donkeys); two frictional accessories. Leather: roller 32c with handle 33 for non-movement causes the disk 34 to rotate, and through the shaft 35 and the corresponding gears, also the leading rollers of the tracks, and these gears are combined in such a way that through the pedal 36 it can be attached. One direction: close motion, movement in opposite directions, for turning in place. The handle 37 serves to squeeze the spring placed in the 3 cup 38 together with the spring: ka 34 down to the non-operating position. The leather roller 39c with the handle 40 drives the disk 41 and through the worm gear 42 a shaft 43 with gears 44 interlocked with the toothed semicircles 45 reinforced in the frames 22; the handle 46, like the hand 37, serves to turn off.

The operation of the machine is as follows. When the motor is turned on and the cutting tools are working, the machine (Fig. 1) starts moving out of the medium by rotating: neither the tracks through the friction device 32 - 38. In this case, the strip 10 makes a cut in the plane 10 - 51, and the chains in the planes 50 - 52 and 53 - 54. When line 10 reaches position 51, the movement of the tracks is stopped by turning off the handle 37 and turning on the other gear 39-45; then, the turning of the frame 22 near the axis 24 and the movement of the entire cutting edge upward begins; at the same time, the -strip 10 will move, cut itself-the way, from position 51 to 55, and the chains will continue cutting through the planes 50 - -52 and 53-54. After reaching 10

55, the caterpillars begin to move again, but in the opposite direction, and the strip goes from position 55 to 56, which ends the cutting out of the whole boulder. For cleaning, its machine can be pulled back or to the side by turning the tracks under the turntable 26, and the control discs 28 must be removed from the recesses formed by the previous kerfs of the chains.

In the visually-meshed device for bringing the strip 10 into reciprocating motion, the crosses 19 associated with the ends of the strip 10 (Fig. 4), equipped with rollers 20 and square shanks 18 directed in the protrusion cavity 17 of the transitional part 7 of the frame, are applied. When the end gear 8 rotates, the roller 20 rolls over a wave-shaped liner 21 that repels the spider 19 to the extreme position (FIG. 4) from which it is. displayed in line 10 under the influence of the cross in another process of the frame; thus, under the action of two crosses 19 strip, 10 makes an oscillatory motion.

The subject of the patent.

1. Device for cutting stones from an array using chain saws and a strip of one form or another provided with cutting elements, characterized in that chain saws 9 (Fig. 1) are mounted on processes 2 of an L-shaped frame 1 between which a cutting strip is installed 10, connected with the ends of the arms of the arms 12 placed in the cuts with the axes 11 and receiving return displacements from the shaft 4 (FIG. 2-3) by means of the clamp 16 with the fist groove 15, acting through the pin 14 and 13 levers 12, in which the device of rotation shaft 4 and the appropriate movement of the cutting instruments to communicate with the supply iomoschi conventional mechanisms.

2, the modification described in paragraph 1, characterized in that

For messages of reciprocating intersections of the lanes 10 (Fig. 1), it is applied to the crosses 19 (Fig. 4) “rollers of the NE 20, fitted, each, square, with the tailings 18, directed to

the cavity of the protrusion 17 of the frame constituting the axis of rotation for the gear 8 of the chain saw 9, each of which gear carries the cam part 21, for acting on the rollers 20.
