Description

Known shock vrubovo-fenders with shock teeth acting from the electromagnets.

In the proposed machine, the shock part of it consists of a series of electromagnets, whose hearts on one side have a firing pin with a clove, and the other rests on a buffer spring; The entire impact part is reinforced in a movable bar, turning right and left and near its axis. To clean the cut during the notch below the impact teeth, there is a conveyor chain with intermittent movement from the bar swing as it moves down. When blasting the machine can be lifted with screws from the side of the bar, and, therefore, can produce blasting packs of coal at different heights.

In FIG. 1 shows the machine in the notch position; FIG. 2-the same machine in the breaking position; FIG. 3 - scheme with a reactive coil; FIG. 4 is another variant of an electromagnet; FIG. 5 -; - circuit with a transformer.

The proposed electromagnetic shock vrubovo-fender machine (Fig. 1 and 2) in appearance Similar to the existing ones. A frame / 7 is placed on the sled / O, to which all parts of the machine are attached. This frame has the ability to rise from the standing bar 2 in the production of breaking.

(129)

A row of electromagnets is located on bar 2 for conducting the cutting and breaking the coal, the cores of which, on the one hand, are fitted briskly with a chuck /, and on the other hand abut a buffer spring. The bar 2 is rotatably fixed in the head 3 of the machine, with a gear system of 4, 5, 6, 7 operating from the camshaft 5, located near its axis; a gear system 4x5 is designed for the cut shaft; the conveyor chain I Bar 2 is attached to the rotary parts to two flanges; on one flange using an eccentric / 2, the bar swings teeth 7 up and down, which is necessary to produce a certain height of the notch gap; on the other flange, with the aid of a screw, it is rotated in order to set the angle for breaking. In this case, the eccentric will turn off, of course (the bar does not swing).

The teeth 7 are bars 2, arranged so that the z-like odd ones are slightly longer (bit type); they are intended to cut through narrow grooves. Even nubs are shorter, cone-shaped and intended to chop the columns of coal between the grooves. Below the teeth there is a small conveyor chain 9, which carries the notch products out of the cutting gap. This chain receives an intermittent motion when the bar is swinging down by engaging the teeth on a fixed flange. Near the bar 2 there is an electrical distribution box / 5, in which there are electrically-active reactive coils or transformers. Without a box 13, the camshaft 8 passes, connected at one end directly to the motor 14, and the other, using gears, with an eccentric 72, rolling the bar when cutting, Motor 14, in turn, is connected using a friction lever device 15 to the masking machine 16 and drum 17 for winding the cable.

In the proposed machine, the percussion units operate using an electromagnet, whereby for supplying the coils their electrical circuit is not broken during alternating-return movements of the striker C (Fig. 3).

According to the invention, two electrical circuits are used: the first (Fig. 3) with a reactive coil and the second (Fig. 5) with a transformer.

In the first case (Fig. 3) in two coils, using an eccentric D, the iron core E is driven. The entrance to coil A, core E makes it possible to obtain a large inductive resistance in its winding, while in coil B there will be a small ohmic resistance, which makes it possible electromagnet B to send a large amperage, which acts on electromagnet B, besides there is no striker C, which will also compress the buffer spring. At this time, the core E quickly turns into the coil B; magnetization of electromagnet A is magnetised and the cushion with a buffer spring and magnet force is thrown forward onto the tooth, etc. The eccentric D rotates rapidly using a special motor (up to 2000 revolutions), gives a number of frequent blows, which, slug, will produce badge work .

In the second case (Fig. 5), the reactive grandmother replaces a single-phase transformer, y. which there are two secondary windings, planted on separate cores. The transformer is designed so that it is possible in a known sequence to break the magnetic circuits (PA or 11V) on one side (as indicated in the diagram) or on both sides (each side separately). In this case, the electromagnets A and B will alternately drive the hammer C.

The breaking of the magnetic circuit must occur using a camshaft driven by the motor M.

The type of electromagnets depends on the power of the machine, which gives a constructive calculation ..

In the second version of the electromagnet (Fig. 4), the hammer C has an additional winding, which is connected in parallel with the winding of coil A. The windings of this winding are directed oppositely, which also makes it possible to enhance the effect of electromagnet A.

The subject matter of the invention.

Electromagnetic percussion cutting machine with percussion teeth, acting from an electromagnet, characterized in that for conducting the cuts and blasting, an angle of electromagnets with percussion teeth, /, 7 (Fig. 1 and 2) is located on bar 2 rotatably fixed in the head 3, with a gear system of 4, 5 b and 7 operating from the camshaft 8 located in the head 3 for swinging a bar, and a conveyor chain 9, 9 is used for cleaning the cut-off gear.
