Abstract

The invention relates to mining promet and is intended for the coal mining. The goal is to increase the efficiency of the monitor by increasing the compactness and working length of the jet. The jet contains a barrel (C) 1 with a nozzle 2 and a fairing located in C 1 along its longitudinal axis. The fairing is made of a needle 3 located with the sharp end 4 in the nozzle 2 with the possibility of longitudinal movement using a cup 5 with a nut 6. The cup 5 is located on the outer side of C 1 and is connected to the rear end of the needle 3 by a threaded connection. The cup 5 is connected to C 1 with the help of a stop nut 7. At the rear end of the needle 3, the segment grooves 8 are made. Rotate the cup 5 with the nut 6. The sharp end 4 of the needle 3 is set at a predetermined distance from the end of the nozzle 2. The water flows over the needle 3 and in the form of a jet is sent to the bottom. 3 il.

Description

The invention relates to the mining industry and is intended for the coal mining.

The purpose of the invention is to increase the operating efficiency of the hydro monomotor by increasing the compactness and the working length of the jet.

Figure 1 shows the monitor, top view; figure 2 - node I in figure 1; on fig.Z - section aa in figure 2.

The actuator includes a barrel I with a nozzle 2 and a fairing located in the barrel 1 along its longitudinal axis. The fairing is made of a needle 3 located with a sharp end 4 in the nozzle 2 with the possibility of longitudinal movement using a cup 5 with a nut 6 located on the outer side of the barrel 1 and connected to the rear end of the needle 3 with a threaded connection. The glass 5 is connected to the barrel 1 by means of a stop nut 7. At the rear end of the needle 3, segmental grooves 8 are made.

5 has a seal 9. Between the flange 10 of the cup 5 and the stop nut 7, balls 11 are fitted to facilitate the rotation of the cup 5.

To remotely control the exit of the needle 3 from the nozzle 2, on the outer surface of the cup 5 there is a screw thread, which is put on a nut and is subsequently rigidly connected to the rod of the hydraulic cylinder. The housing of this hydraulic cylinder is mounted on the barrel 1.

To ensure that the sharp end 4 of the needle 3 does not oscillate during the operation of the jet monitor, the needle 3 has streamlined ribs before entering the nozzle 2.

The actuator works as follows.

Before supplying pressurized water to the barrel 1 of the jetting machine, the sharp end 4 of the needle 3 is set at a predetermined distance from the end of the nozzle 2, for which the cup 5 is rotated and

together with it, the nut 6, which, being engaged with the thread at the rear end of the needle 3, acts on the needle 3, causing it to move along the axis of the barrel

A stream of water flows around the needle 3 and in the form of a jet is directed to the bottom.

Claims (1)

Claims of the invention A hydromonitor comprising a barrel with a nozzle and a fairing installed in the barrel along its longitudinal axis, characterized in that, in order to increase the efficiency of the monitor by increasing the compactness and working length of the jet, the fairing is made of a needle located with a sharp end in the nozzle with the possibility of longitudinal movement by means of a cup with a nut located on the outer side of the barrel and connected to the rear end of the needle by means of a threaded joint, the cup being connected to the barrel by means of a stop nut, and segment grooves are made at the rear end of the needle. 1 & t U / B // LA & //// U //// L FIG. 2 8 7 1chchchu figs / I -a
