Description

The invention relates to hoisting and transport machinery and can be used in mining for the production, delivery and loading of ore from collapsed blocks in underground mining and in other industries.

By author St. Nfc 818991.cl. 65 G 27/08 discloses a vibratory feeder comprising a tray mounted by means of rolling bodies on support elements and a drive. The rolling bodies are made with two parallel working surfaces located symmetrically crosswise relative to the vertical axis. The tray is mounted with a lift towards the discharge end.

The disadvantages of this vibratory feeder are

low productivity, due to the rise of the discharge end of the tray, while the direction of the disturbing force created by the vibrator is not parallel to the movement of the ore, but at an angle that

helps to compact ore on the tray, rather than dropping it from the tray;

low reliability due to significant overload of the vibrator, since during operation of the vibrating feeder the amount of ore on the tray due to its constant compaction increases to the maximum value and the vibrator from overload fails.

The quick exit of the vibrational feeder is facilitated by the impact of the rolling bodies on the supports with their horizontal surfaces and the impact of the tray on these working surfaces of the rolling bodies; Significant additional noise caused by impacts of the rolling bodies against the supporting elements and impacts of the tray on the rolling bodies, as well as the fall of ore onto the tray during its operation.

By author St. Nf 813681, cl. 65 G 27/08 discloses a vibration conveyor, a tightening tray mounted with elastic supports on the frame, and a vibration drive, as well as shock absorbing slots installed between the anti-friction. nna70

WITH

with the elements and protrusions of the frame on top of the nose, which are parallel to the planes of the action of the disturbing force, the antifriction elements are made of two parts having cushioning pads, one of which is placed on the protrusions of the frame, and the other on the supports of the tray.

The disadvantages of this known vibratory conveyor are

low productivity, which is caused by the direction of the disturbing force at an angle to the direction of movement of the unloaded material, which contributes to the compaction of the material on the tray, rather than dropping the material from the tray,

low reliability, which is due to significant overload of the vibrator, since during the operation of the vibratory conveyor the amount of material on the tray due to its

continuous compaction increases to

limit value and the vibrator from overload fails.

The quick exit of the vibration conveyor is facilitated by the rapid wear of the shock-absorbing pads; increased noise due to shocks of material falling on the tray during its operation.

The purpose of the invention is to increase productivity and reliability.

For this, a vibrating feeder including a tray connected by means of supports and elastic elements to a frame and a vibrator is provided with a horizontal hinge

rum mounted under the frame at the discharge end of a vertically placed power cylinder mounted under the frame at the loading end, and the supports are made in the form of cylindrical bodies of quality

nor with bearings, and the elastic elements are installed counter to one another and are made with adjustable force. in this case, the tray is installed parallel to the direction of vibrator vibrations

Fig. 1 shows a vibrating loop, the working surface of the tray is horizontal; in FIG. 2, the assembly I in FIG. 1 in FIG. 3 - vibration feeder, the working surface of the tray is tilted towards the load end

The vibrating feeder includes a tray 1, mounted by means of cylindrical rolling bodies 2 equipped with bearing bearings 3. on a frame 4 vibrator 5 g, directional vibrations. Tray 1 is installed parallel to the direction of vibrations of the vibrator 5. Under the tray 1 on the frame 4 there are installed elastic eavesdrivers opposite one another made with re

attached to the bottom plane of the tray 1 of the bracket 6. of the adjustable stand 7, attached to the frame 4. and the spring 8 installed between the bracket 6 and the adjustable stand 7. The adjustable stand 7 to the frame 4 is attached with bolts 9 and washers 10. It is rigidly attached to the frame 4 bosses are attached 11. into which thrust bolts 12 with locknuts are screwed 13. A horizontal hinge 14 is mounted under the frame 4 at the discharge end of the tray 1, attached to the foundation and interacting with the frame 4. At the loading end of the tray 1. a vertically placed force is installed under the frame 4 howl cylinder 15 cooperating with the frame 4 by a hinge 16. The ore designated key. 17.

The feeder operates as follows.

Vibrator 5 creates disturbing forces. The directions of the disturbing forces created by the vibrator 5 are indicated by arrows parallel to the working surface of the tray 1. When the vibrator 5 is operating, the tray 1. resting on the cylindrical rolling bodies 2 performs oscillations with a given and adjusted amplitude in the directions indicated by the arrows. The oscillation amplitude of the tray 1 is controlled by changing the tightening of the spring 8. This is done by changing the distance between the bracket 6 and the interchangeable stand 7 of both counter elastic elements, i.e. by mixing the interchangeable stand 7 relative to the bracket 6. The oscillation amplitude of the tray 1 will always be constant, which ensures constant performance when the working surface of the tray 1 is horizontal.

In order to increase productivity, a power cylinder 15 is activated, which rotates the tray 1 with the frame 4 on the hinge 14 by a predetermined amount. Bearing bearings 3, in which cylindrical rolling bodies 2 are mounted, provide free, easy, unobstructed rotation of the cylindrical rolling bodies 2, as a result of which the vibrations of the tray 1 are light and unobstructed. This makes it possible to increase the reliability of the vibration feeder, since during operation of the vibration feeder the tray 1 moves in the direction of the disturbing forces of the vibrator 5. then the tossing of the ore 17 is excluded, which eliminates its compaction on the tray 1, the productivity is increased by vibration of the feeder. Rotate the vibrating pitz pch on hinge 14 by means of HILORI. chinshdre 15

significantly improves productivity and ensures that it can be adjusted
