PNVV1MA | T1Ichic vibratory buikeroe boot device (device oderl it pneumatic actuator and V1ib | p; coaxial bowl with orienting devicesMy. PNVV m01Drive consists of a vibrator and a switch. The developed cash actuating element (Fig. 1) is in place for a vibrator (a. thin thin-walled KaiMepy U, with an elliltic (oval); on the cross and longitudinal sections of the mass-media.

Some of them are free and the other is rigidly attached to the cork 2 by soldering, gluing, welding or removing them with the help of technological linings. To fix the position of the chamber, the flaccone 3 plugs are installed in the groove 4 n of the roti (weighing 5 (in the bottom support plate). At the top of the camera there are plates 6 that ensure the constancy of the magnitude of the effect | in the new area in the predetermined limit and oscillations. In the protrusion (the cusher section is closed with a lid 7. The chamber is broken by the chamber / under the action of the pooling pressure (mainly in the direction of the increment of the small axis of the cross section contour)) is transmitted by the editor CTBOiM of the reference (Plate 6, iii ii ii))) tough connected to pin 8, through ball 9 to thicket 10, on the inner surface of which there is a tray in the form of a BINT OPTICAL “.

The switch consists of a body // with holes 12 and 13, 14 and 15 for the supply and removal of the compressed pelvis, respectively. Inside the housing there is a spout 16, which includes an annular flow path 17. On one side, the spindle is spring-loaded with a spring 18, the rigidity of which is adjusted by means of Blint 19 through the clamp 20. The radial 21 and axial 22 holes are made in the head of the piston. The bore 22 ends with a movable axial needle 23. The cross-section of the needle bore is recirculated to the screws 24. The valve pair 25, 26 forms two chambers 27 and 28.

The percussion valve is attached to the chamber flange / rigidly (by soldering; welding) or detachably using a gasket 29. In the initial position, the piston 16 under the action of the spring 18 occupies the right extreme position (Fig. 3). In this case, the chambers are divided by rubbing in the valve pair 25 and 26, the hole 15 is closed. The power supply main 30 via the connector, the opening 12, the annular groove 17 and the openings 13 and 31 communicate with the internal cavity of the chamber 1. The increase in the overpressure in the cavity / leads to its deformation, mainly in

the direction of the small axis of the cross-sectional contour, and consequently, to the movement of the thicket through the plate 6, the shafts 8 and the bowls "9. At the same time, the compressed gas from the chamber's internal cavity / through the holes 32 and 14 in the chamber 28, the holes 22 and 21 are throttled into the chamber 27. The pressure in the chamber 27 is sufficient to overcome the force of the spring 18, the piston 16 moves T | C 1 left, opening the valve pair 25,26 with the caiMbiiM and communicating the chamber 28 and, consequently, the internal cavity of the chamber / c chamber 27, so as to with a maximum amplitude of pressure fluctuations in the chamber / less pressure in chamber 27, this leads to an abrupt increase in pressure in chamber 27 and the creation of an I1 pulse of oil, under the influence of which the piston squeezes the spring 18 stronger, opening three exhaust ports and jointly B (inner chamber cavity / atmosphere). Temporarily overlaps hole 12, i.e., with the exhaust gas, the supply line is shut off.

A steady pressure drop in the inner cavity of chamber 1 will cause the piston 16 to move to the right under the effect of the spring force, closing the outlet 15, the valve pair 25 and opening the supply line 30. The cycle repeats.

| Vertical oscillations of the vibrator by four inclined squad plates 33 are transformed into oscillations of the thicket 10 of the bunker by the supported.

The proposed pneumatic drive creates an asymmetric cycle of pressure pulsation of compressed gas, i.e. it increases more slowly and decreases rapidly. The oscillation amplitude is adjusted (it is not carried out by adjusting the spring rate of the spring 18 by means of the screw 19 and the clamp 20. The pulsation frequency is regulated by the degree of throttling of the mixed gas into the chamber 27 of the screw 24. The vibratory insulation of the bunker loading device is installed on the shock absorbers. Twisted cylindrical springs 34 relatively low stiffness. The base of the 35th vibration will be transferred - the smaller, the greater the difference between the oscillation frequency of the part of the bunker on the springs and the natural frequency of oscillation of the counterweight 5 on coil springs.

With the appropriate arrangement of this vibrator, it is possible to provide both vertical and horizontal oscillations of the thicket, i.e. translational vibration motion.

Subject invention

A pneumatic vibratory hopper loading device, made in the form of a pneumatic device and a vibrating thicket with orienting devices, is different, so that, in order to simplify the design, increase reliability and reduce the size, the vibrator is 1 H in the form of a lock / naked thin-walled metal chamber with an elliptical (with an elliptical body, an elliptical cross section and longitudinal section, located in the osnozali hopper, and on the flange of the chamber is an adjustable switch piston t-Ipa, in a spring-loaded spring element

which has longitudinal and radial holes, as well as an automatic hole, and a supply groove with a circular cavity of the chamber with an annular groove.
