Description

In the author's certificate no. 30240, a stone cutting machine is described, made of a vertical frame mounted on a trolley moving with tracked belts. On the frame, the drills can be moved in the vertical direction, driven by two engines mounted on the frame, and for cutting out stones are belt pids with cutters, thrown over the drills, located in the bearing on the vertical and horizontal sides of the half-frames, for which On the fixed frame serve two screws. With this movement, cutting of the back side of the stones takes place with the help of cutting saws thrown over mutually opposite pairs of drills located on the vertical sides of the half-frames. at

According to the proposed modification of the machine, the rope of the first saw covers the drills near the ends of the drills, where the grooves are made for transferring the rotation to the saws.

In FIG. 1 is a side view of the machine; FIG. 5 is a view from above; FIG. 3 is a front view of it; FIG. 4-drill and saw.

The main cutting tools are eight drills 4. and two closed-wire saws 5, n% ripped each through four drills. The saw consists of a cable with coil springs and cutters mounted on it and thrown through the grooves of these drills (Fig. 1, 2, 3 and 4). The drills 4, eight in number, rotate in bearings attached to the frame 7, whereby the rotation is transmitted to them by flexible shafts 6 from a system of gears inserted into the box 7 and set in motion by the drive 8..

The remaining main parts of the car are trolley 2 and support 3. The cart 2 ira is resting on four wheels, of which two wheels 9 serve to move it to the sides, and two wheels 70 to move forward and lazad.:,

The movement of the machine, is done by hand with the screws pressed

11, in order to move to the sides, by rotating the handwheel 12 and the screw 13 (FIG. 1), turn the double-arm lever 14 in such a way that the roller 75 is lowered and thereby separates the wheel 0 from the ground. To move the machine forward and backward, the handwheel 72 rotates in the opposite direction, as a result of which the lever 14 lowers the wheels 16 to the ground (Fig. 3), raises the wheels 9: The supor 3 moves up and down the columns / 7 using the handwheel 18 ( Figures 1 and 2), which act like a conical pair of wheels on a screw 19, passing through a nut integral with the support 3. Three sleeves 20 are also attached to the support 5, through which two rods 21 pass, non-. The frame 7. The rods 21 move in a horizontal direction by simultaneously rotating by hand two screws 22, interconnected by a chain. For stability, the machine is pressed to the ground with screws 77.

The operation of the machine is as follows. After the yctHHOBKH machines, by means of squeezing screws 77, the motor a is turned on and the drills 4 are driven into rotation and two saws 5 transferred through them are driven into motion. Then, the frame 7 is driven forward, due to

what flexible saws 5 will enter the array, the thickness of the stone (Fig. 1); after that, the caliper 3 and, consequently, the frame 1, are vertically displaced downward by a distance equal to twice the thickness of the stone, and finally the frame 7 is moved horizontally backward until the drills 4 with the saws 5 are out of the array. Thus, every four drills with one saw, when moving the stone to double thickness, cut out three pieces from the array, and, with vertical movement, the rear edges are cut by the flexible saw 5, and the lateral edges are drilled 4.

The machine, built on the attached scheme with eight drills, with one cycle (moving frame 1 forward, down and back) will give six ready-made piece stones. After a full cycle, the maschine needs to be moved sideways for the length of one stone to repeat the process.

The subject matter of the invention.

Modification of a machine for cutting stones from an array according to the author. swith No. 30240, characterized in that the wire saws 5 (Figs. 1, 2, 3 and 4) cover the drills 4 near the ends / drills, where grooves are made to transfer the enemy.
