Description

In addition to the solid-stone construction machine described in patent No. 14132, instead of chain saws, rigid npopesHt ie saws with reciprocating motion and a row of drills were used for drilling - the bottom row of holes.

In FIG. 1 is a side view of the machine; FIG. 2 is a view from above; FIG. 3 is a vertical section of e along the LAN line in FIG. 1); i of FIG. 4-way to install the machine and the scheme of its work.

The machine on an iron riveted bed with four wheels and trimmed from angular iron moves on portable rails. To reduce friction, the movement of both saw-carrying brackets is provided by rollers placed in cast-iron sidewalls with recesses of the sled 16 (Figs. 1 and 2). The slide rails are equipped with an adjuster (with wedges for picking up the slack. The movement of the car is transmitted from the automobile type 1 through the speed box 2 through a chain

through the chain teeth 3, 3, mounted on the shaft b with a nut 18, which moves the saw-saw arm forward and backward; at the same time, the shaft If, with the help of coupling bevel gears 20 and the connecting rod 21, the upward and downward cutting saw tX is reported to be transmitted to the two brackets 6 with slotted vertical to horizontal saws from the shaft b, two conical ones. gear 4, 4 and screw -A, pass u, through the thrust nut U and guide bracket 5 (Fig. 2). The horizontal and vertical saws 11, 12 are driven by the B movement of the gears 7, 7 and the crank roller 9 by means of two slats 10, the rocker arms 10. It is transmitted to the drills 14 by the system of chained housings 13, and they simultaneously back and forth. Therefore, the work of saws and drills occurs simultaneously. With saws and drills 1 1 and a certain depth required for

stone, the machine is automatically stopped by the lever 22, the deflecting action of the tide of the nut 23 of the bracket 19 and its other end on the engine cone pedal, squeezing it. Then the handle 24 through the gearbox 2 moves to the reverse; the handle 24 simultaneously switches on a cone, which at the end of the reverse travel is activated in the usual way, and the handle is shifted to the forward stroke.

The machine works as follows: first, choose an angle for the cutting saw in the rock and level the platform for the rails, then set the machine so that the drills have position 1 (Fig. 4), then the machine is given a stroke and drills are drilled in the rock which stop the ends of the vertical saws B in the lowest position; then the machine is retracted, moved to the left, the drills are given position 2, advanced in motion, and vertical saws and drills begin to work simultaneously; after that, they move backward and move the machine to the left, prn than the drills will get position 3, the machine will move forward and at the same time horizontal saws will work, for which in the extreme left position the vertical cuts will be used as vertical saws; again move backward, move the machine still to the left, the drills get position 4, again give the machine a stroke forward, and together with drills, vertical and horizontal saws it works and, rejects saw b (Fig. 4). From now on, for each turn back and forth, thirty-six stones are obtained. After cutting, the stones are kept from falling by a wooden comb inserted into horizontal cuts. .

The subject of the patent.

1. Modification of the machine for cutting construction stones from the rock described in patent No. 14132, characterized in that, instead of the saw-cut saws, rigid cutting-through saws were used.

2. A machine for cutting out building stones from a rock, indicated in point 1, characterized by using a row of drills for drilling a lower row of holes.
