Description

Изобретение относитс к подъемнотранспортному машиностроению, а именно к вибрационным питател м, исполь .эуемым дл выпуска руды в горнодобы-. вающей промышленности с одновременным выделением мелких классов, обогащенных полезными компонентами.The invention relates to a lifting transport machinery, namely, vibratory feeders, used to release ore to mining. industry with the simultaneous allocation of small classes enriched with useful components.

Известно устройство дл выпуска горной массы, включаю1 1ее рабочий орган в виде предварительно изогнутого листа, вибратор и амортизаторы 11 .A device for discharging rock mass is known, including a working body in the form of a pre-curved sheet, a vibrator and shock absorbers 11.

Наиболее близким к предлагаемому вл етс вибрационшлй питатель дл выпуска руды, содержащий рабочий ор .ган из гибкого листа, уложенного на раму, борта закрепленный на листе вибратор 2.Closest to the present invention, there is a vibrating feeder for ore output, containing a working op. From a flexible sheet laid on the frame, the bead attached to the sheet vibrator 2.

Недостатком известных устройств вл етс невозможность выделени мелких классов руды, обогащенных полезными ископаемыми, из-за потери при транспортировке и многократных перегрузках , что существенно сужает технологические возможности питател .A disadvantage of the known devices is the impossibility of separating small classes of ore, enriched with minerals, due to the loss during transportation and repeated overloads, which significantly reduces the technological capabilities of the feeder.

Цель изобретени - раа-жрение технологических возможностей путем обеспечени разделени транспортируемой руды по крупности.The purpose of the invention is to develop technological capabilities by ensuring the separation of transported ore by size.

Указанна цель достигаетс тем, что вибрационный питатель дл выпуска руды, включающий рабочий орган из гибкого листа, уложенного на раму, борта и закрепленный на листе вибратор , имеет порог рассева, выполненный в виде сужаюцихс в направлении транспортировани колосников, установленных под углом к листу.This goal is achieved by the fact that a vibrating feeder for ore production, including a working member from a flexible sheet laid on the frame, beads and a vibrator mounted on the sheet, has a sieving threshold, made in the form of constrictions in the direction of transport of grates installed at an angle to the sheet.

Кроме того, лист снабжен раструбом с упругим уплотнителем и опорами, In addition, the sheet is supplied with a bell with an elastic seal and supports,

10 при этом раструб размещек под колос- никами, а опоры установлены с возможностью прижати раструба к листу.10 with the bell placed under the grate bars, and the supports are installed with the possibility of pressing the bell against the sheet.

Вибрационный питатель дл выпуска руды состоит из гибкого листа 1, бортов 2, перекрывающих днище люка Vibrating feeder for the release of ore consists of a flexible sheet 1, sides 2, overlying the bottom of the hatch

Claims

20 (ore passages) and directing the flow of ore strictly onto a flexible sheet, a vibrator 3, a socket 4, a replaceable tank 5 made in the form of a box, flanging 6 for directing the flow of ore, a transport surface -7 that belongs to sheet 1, separators 8, through grooves 9, made in sheet 1, frame 10, on which sheet 1 is loosely laid, damping element 11, element 12 regul. for pressing the socket 4 to the sheet, the elastic seal 13 mounted on the socket, the axis 14 belonging to the socket, and the support 15 of the socket. The vibrating feeder works as follows. . The flexible sheet 1 is brought into oscillatory motion by the vibrator 3. The ore lying on the sheet 1 at an angle of repose ot begins to transfigure along the transporting surface 7. Under the action of sil vibration, the ore is partially divided into layers, with the smallest heaviest classes transporting surface 7, and large pieces of ore float upwards. Changing the direction of movement of the ore due to the sieving threshold set at an angle to the transportation surface 7 contributes to the separation of the ore into layers. On the threshold, further intensive separation of the ore occurs, aided by the separators 8, made in the form of a triangle. Then, small classes of ore fall through the through grooves 9 of the flexible sheet 1 into the socket 4 and are collected in a removable tank 5, and the large ore enters the carriage 16. In order to eliminate jams of ore in the gaps between the dividers 8, the grates are made tapering in the direction of transport ore. In order for the selected fine fraction not to adhere to the surface of the bell and not to linger on them, the bell is pressed to the flexible sheet 1 through the elastic seal 13, the shaft axis 14 and the damping element 11 by the adjustment element 12. Such a constructive relationship allows the bell to oscillate with the frequency of forced oscillations of the flexible sheet 1 in the radial direction relative to the axis 14 and in the direction perpendicular to the sheet (arrows C and D) within the elastic deformation of the damping element 11 and the elastic seal 13. The invention allows when transporting ore, ensure its separation by size into classes, which leads to the exclusion of the loss of small classes of ore during its delivery to the processing plants. Claim 1. Vibration feed for ore production, including a working body. From the flexible sheet laid on the frame, the bead and the vibrator mounted on the sheet, characterized in that, in order to expand the technological capabilities by ensuring the separation of the transported ore by size, it has a sieving threshold, made in the form of tapering in the direction of transport to the glossaries installed under an angle to the sheet .. 2. The feeder according to claim 1, in connection with the fact that the sheet is equipped with a socket with an elastic sealant and supports, while the socket is placed under the grates, and the supports are installed. New with the possibility of pressing the bell to the sheet. Sources of information taken into account during the examination 1. USSR author's certificate No. 275835, cl.
