The stops 14 are installed in the guides 15 and are kinematically connected with a two-arm two-arm interacting with the stop screws.

The invention relates to a lifting machinery industry, namely to vibratory bunker feeders, and can be used in the loading devices of machine tools and automatic lines.

The purpose of the invention is to increase the reliability of the feeder.

Figure 1 shows the vibratory bunker feederJ, a general view; in fig. 2 is a section AA of FIG. one; Figs and 4 show variants of cams.

The vibratory bunker feeder contains a reaction plate 3 mounted on a fixed base 1 on shock absorbers 2 with iff installed in liners 4, shaft 5 connected to a thicket 6. The torsional vibration stimulator consists of an electromagnet 7 mounted on a reactive plate 3 and a core 8 fixed on the shaft 5 and elastic elements connected to the reactive plate 9. The vibrating feeder is provided with an intermediate plate 10 mounted on the reactive plate 3 by means of ball bearings 11.

On the cup 6, by means of the hinges 12, the cams 13 are fixed, interacting with the stops 14 fixed on the intermediate plate 10. For fixing and moving the stops serve guides which can be made in the form of grooves 15, and the hinged two-arm lever 16 with the stops screws 17,

The profile of the cams 13, their relative position with the stop h 14 determine

the throwing angle ((|) transported to; - items located in the bowl 6. So, if the bearing surface of the cams 13 is {circumferential to a circle with radius R), then the throwing angle is determined by the equation

where t is the angle between the perpendicular rum, lowered onto the support from the center of the circle, and segment 1, which connects the center of the circle with the hinge 12; A 1 / R.

The cams 13 can be made in the form of rods 18 with a ball bearing 19, the shaft 5 is spring-loaded with a spring 20 in the axial direction relative to the reactive plate 3.

The device works as follows.

When the electromagnet 7 is turned on, the shaft 5 starts to make torsional vibrations together with the bowl 6, which are also transmitted to the cams 13. When they move, the bowl 6 rises and lowers. From the sliding of the torsional vibrations of the bowl with their vertical movement, screw oscillations occur, in the bowl 6. To change the size of the vertical component, which determines the speed of movement of the transported products, it is necessary to change the position of the stops 14, which is achieved by changing m position two shoulders ry-. chaga 16 by means of j-screws 17.

The presence of only one electromagnetic oscillation drive improves the reliability of the vibrating hopper feeder.
