Abstract

The invention relates to devices operating on the principle of percussion during stone processing, and allows for improved performance by reducing the period for replacing the carbide plate with. her wear. The air entering the cavity of the cylinder, through the spool device drives the piston-hammer, which, when interacting with the rod-indenter 11, makes a reciprocating motion. At the end of the rod-indenter 11, a cylindrical body I is installed through the conical bore 10, which, together with the rod and indenter I, is mechanically fixed with a piston-hammer with a special fork and compression spring dp to return the rod-indenter 11 to the initial position. Making a reciprocating motion of a certain frequency, the cyclic body 1 strikes the surface of the stone. 4 il. sl 00

Description

The invention relates to devices based on the principle of impact when processing stone, and can be used in the separation of large blocks in stone processing industry.

The purpose of the invention is to increase productivity by reducing the time for replacing the carbide plate when it is worn.

Fig, 1 shows the proposed device, obpvy view; in FIG. 2, section A-A in FIG. 1; Fig, 3 - the proposed device, the section; on fig 4 - view B on, 3,

The stone processing device includes a cylindrical body 1 with an axial bore 2 for removing breakage products that enter the destruction zone using channels 3, a carbide plate 6 is attached to one of the ends of the body 1 using a removable collet clamp 4 with a conical surface 5 A dovetail tails, a removable collet clamp 4 is installed in the conical bore of the housing and secured to it with a screw 7 with an axial bore 8, and a carbide plate 6 is placed in a groove 9, made at the opposite end of the housing 1 of the removable collet clamp 4; At the other end of the housing 1 in the tapered bore 0 there is a boom-indenter 11 of the percussion mechanism with a compressed air system (not shown); Screw 7 is mounted through a jumper in the bore 12 1 and screwed into the threaded hole of the removable collet of clamp 4,

The device works as follows

The air entering the cavity of the cylinder, through a spool device, sets in motion a rotary hammer, which, when interacting with the indenter rod 11, makes a reciprocating motion. At the end of the rod-indenter P, a cylindrical body 1 is installed through the conical bore 10, which, together with the rod-indenter 11, is mechanically fixed with a piston-hammer with a special fork and compression spring to return the rod

the indenter 11 to the initial position.

Making a reciprocating motion of a certain frequency, the cylindrical body 1 strikes the surface of the stone, destroying it,

The products of destruction from the cutting zone are removed by air through the axial hole 8 of the cylindrical body 1 and the channels 3 on the removable collet 3, the clamp 4,

Claims (1)

Invention Formula A stone processing device containing an indenter rod with a central axial hole for removing breakage products, secured to it by means of a fastening element, a cutting body with a carbide plate and a mechanism for reciprocating an indenter rod, characterized in that performance by reducing the time for replacing the carbide plate when it is wear and tear, the cutting member is the form of a cylindrical body divided by a bridge, the upper part of which is connected to the indenter rod, and in the lower inner; the conical part is mounted a collet chuck with an outer conical surface, fastened to the bridge with a screw with a central hole to remove the products of destruction, and a fastening Part of the carbide plate is made in the form of a dovetail that enters the collet clamp.
