Description

The invention of ognosigs for | -orioi equipment, in particular for tunneling machines, is intended for breaking rocks.

11, e. The first invention was the reduction of the energy intensity of breaking one mass due to the formation of an ogkrgg (5 cleaving of the bottom rocks and the exclusion of the central part of the performance of the first) broken body.

FIG. 1 schematically shows a rotor IC 1O; 1nite: 1HH) 1st Org an, side view; in fig. 2 view A in FIG. one; in fig. 3 section B B on fi1. 2

The rotary conditioning body includes beams 2 fixed to Ba.iy 1, on which the tool holders are mounted with 3 e cutters. The toolholders 3 are made in the form of shortened two-legged two-legged six-sided bins with one side equal to the oppositely-facing sides and the right-angled planes 7 and 8. facing the bottom side. Beams 6 are located tangentially to the inlet 5 and are adjacent to it by the locations of the vertices of 9 beams. The rock-tearing backlash 10 of the logger 5 is made concave to the side. The distance between the incisors 4 pas shortened parts of 8 beams 6 and on parts of 7 in the zone

symmet | a) with respect to the line adjoining the indent 5 is twice as large as not OS: the os (nth part 7 of beam 6 directed to the periphery of the actuator). And in beams 6, I can be filled with AND windows for spilling out mountain masay.

The proposed ispolpitelny body works as follows.

When nodachi executive body on noronpy massif is drilling on the annular groove, delineated by the tops of the two-shouldered beams 6, and then to both sides of the groove. As all the incisors come into operation, the formation of the infestation is created by the intersection of two coaxial, but in different directions, directional cones or similar bodies of the axis, outlined by incisors, arranged on beams 6 and in the burr of the n. : 1no to the inlet 5 provides each subsequent cutter, to) located on their tops 9, working in the mode of spallation. The processing of the middle part of the bottom, amounting to twice the number of tool holders, leads to the formation of an array of species at the bottom of the rock that is constantly open1x to wake up the broken rock mass of the rings.

Claims (2)

1. A ROTARY EXECUTIVE BODY OF A DRIVING COMBINE, including a drive shaft on which beams are mounted with toolholders with cutters mounted on them, and a centrally located bore with cutters, characterized in that, in order to reduce the energy consumption of rock breaking due to the formation of open rocks for cleaving rocks face, tool holders are made in the form of two-shouldered beams shortened on one side with equally inclined to opposite sides and forming at an apex an acute angle by planes facing towards oia, while the beams are located tangent to the borehole, the rock-breaking surface of which is made concave and adjoins to it by the locations of the vertices of the beams. 2. The executive body for π. 1, characterized in that, in order to exclude the filling of the central part, the executive body with the broken rock mass, the installation step of the cutters on the parts of the tool holder beams that are shortened and symmetrical with respect to the line of contact with the bump is twice as large as the rest of the beams.
