Изобретение относитс к гидромониторам , примен емым, например, дл разрушени горных пород, добычи угл и т.п.The invention relates to hydromonitors used, for example, in rock breaking, coal mining, and the like.

Известен гидромонитор с воздушным пульсатором,включающий ствол с насадкой и полой трубой дл подачи воздуха Щ.Known hydromonitor with an air pulsator, comprising a barrel with a nozzle and a hollow pipe for supplying air

Такой гидромонитор не обеспечивает высокой частоты пульсации.Such a monitor does not provide a high frequency pulsation.

Известна также насадка гидромонитора, в которой пульсаци напора обеспечиваетс гидроклапаном, в частности, в виде вращающейс турбинки 2 . Такое исполнение не обеспечивает вьсокой частоты пульсации, так как турбина-клапан, на груженна осевой силой и расположенна в части насадки с относительно низкой скоростью жидкости, не может иметь большого числа оборотов. Кроме того, работа в режиме золотникового клапана, JQ турбина не обеспечиваел- мгновенного перекрыти канала.A jetting nozzle is also known, in which the pressure pulsation is provided by a hydrovalve, in particular in the form of a rotating impeller 2. This design does not provide high frequency pulsations, since the turbine valve, loaded with axial force and located in a part of the nozzle with a relatively low fluid velocity, cannot have a large number of revolutions. In addition, operation in the mode of a spool valve, JQ turbine did not provide - instantaneous closing of the channel.

Цепь изобретени - повышение эффективности увеличени частоты пульсации.The circuit of the invention is an increase in the efficiency of increasing the pulsation frequency.

Это достигаетс тем, что устройство дл создани пульсации вьшолнено в виде зубчатого колеса, установленного касательно к струе жидкости. С целью устранени струи на торцах зубчатого венца колеса установлены боковые диски.This is achieved by the fact that the device for creating a pulsation is effected in the form of a gear mounted in relation to the jet of fluid. In order to eliminate the jet, side discs are installed at the ends of the gear ring.

При этом зубчатый венец колеса расположен в канале, ограниченноь- с трех сторон, а зубчатое колесо имеет автономный привод врашени .In this case, the gear rim of the wheel is located in the channel, limited on three sides, and the gear wheel has an autonomous drive of the turner.

На фиг. 1 изображена насадка гидромонитора с зубчатым колесом, установленным за срезом сопла; на фиг. 2 - разрез А-А на фиг 1; на фиг. 3 - насадка с колесом, установленнык в срезе сопла; на фиг. 4 - разрез Б-Б на фиг. 3.FIG. 1 shows a nozzle of a hydromonitor with a gear wheel mounted behind the nozzle section; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - nozzle with a wheel installed in the nozzle section; in fig. 4 shows a section BB in FIG. 3

Claims

The nozzle 1 is rigidly fixed (or made in one piece) bracket 2, in which a gear wheel 4 is installed by means of rotation bearings and vali 3. The gear end of the wheel is tangentially (tangentially) relative to the fluid jet and closed at both ends by disks 5 The gear crown can use :: directly in the nozzle (see fig. 3), while in the nozzle section, the channel 6 is closed, closed on three sides {see, fig. four). When using the nozzle on monitors with a continuous jet of fluid, the gear wheel is displaced freely rotating on bearings on monitors with a pulsed fluid supply, the gear can be (if necessary) kinematically connected with a rotational drive, for example, from an electric motor, pneumatic (or hydro) turbine. The nozzle works as follows. The liquid jet 7 from the nozzle 1 acts on the tooth of the wheel 4 and causes it to rotate, while the circumferential speed of the gear) of the crown is close to the speed of the jet. The teeth of the wheel cut through a continuous stream into separate portions with a length approximately equal to the diameter. Due to synchronous rotation and small (relative to the wheel diameter) tooth height, the relative speeds of interaction between the teeth and the liquid are small, and the design is efficient even with the highest pressures that characterize modern hydromonitors. For example, when the pressure of a fluid is 2OOO atm, the speed of the jet and the toothed veneer is close to 600 m / s, but the velocity head is located on the elements of the teeth, not A5) 50. atm. At the same time, the pulse rate: the jet can reach 2 () OOOO pulses per 1 s, many times more than limestone devices. The performance of the ring gear with side discs 5 or its location in channel 6 allows reducing the expansion of the jet by noc; je interaction with the pub 1, choke, pack (; elongation of the range and energy of the jet in the ecop effect. Monitor, pulsed in, at the head of pressure can (at the initial moment, when the wheel is stationary) destroy the crown teeth. In these cases, the wheel is preliminarily brought into synchronization; rotation by an autonomous drive described in the vyg. Invention formula 1. The nozzle of the jetting machine a device for creating pressure pulsation, so that, in order to improve the frequency of pulsation, the device for creating a pool; the scatter is performed in the form of a gear wheel, which is set in relation to the spray jet. 2 Nozzle according to Claim. 1, characterized in that, in order to eliminate the jet, side discs are mounted on the ends of the gear ring, 3. The tip according to claims 1 and 2, characterized in that the ring gear wheel is located in the channel bounded from three sides. 4. The nozzle according to Claim. 1, wherein the toothed wheel ring has an autonomous drive of rotation. Sources of information taken into account during the examination 1.
