Изобретение относитс к оборудованию дл ленточных конвейеров, а именно к устройствам дл подачи крупнокусковой горной массы на ленту конвейера.The invention relates to equipment for belt conveyors, namely, devices for feeding lumpy rock to a conveyor belt.

Известно устройство дл загрузки ленточного конвейера, включающее установленный на раме посредством упругих элементов наклонный лоток с направл ющими боковинами и криволинейной нижней частью 1.A device for loading a belt conveyor is known, which includes an inclined tray mounted on the frame by means of elastic elements with guide sides and a curved bottom part 1.

Недостатком устройства вл етс то, что в этом устройстве создаютс только вертикальные колебани , что не позвол ет существенно снизить коэффициент сопротивлени движению груза по лотку, а следовательно, повысить скорость груза на выходе с лотка.The disadvantage of the device is that in this device only vertical oscillations are created, which does not allow to significantly reduce the coefficient of resistance to movement of the load on the tray and, consequently, increase the speed of the load at the exit from the tray.

Известно устройство дл загрузки ленточного конвейера, включающее лоток, верхн часть которого закреплена на упругих опорах , а нижн расположена на опорных элементах 2.A device for loading a belt conveyor is known, comprising a tray, the upper part of which is fixed on elastic supports and the lower part is located on supporting elements 2.

Недостатком этого устройства вл етс то, что невозможно обеспечить наперед заданную траекторию движени лотка и режим его колебаний будет зависеть только от деформации упругого элемента. При этом сопротивление перемещению груза по лотку будет значительным (хот вибраци способствует снижению коэффициента сопротивлени движению груза по лотку),что приводит к снижению скорости движени материала на выходе с загрузочного лотка и при несовпадении вектора скорости грузопотока 5 с вектором скорости ленты будет происходить интенсивный износ конвейерной ленты.A disadvantage of this device is that it is impossible to provide a predetermined path of movement of the tray and its mode of oscillation will depend only on the deformation of the elastic element. At the same time, the resistance to movement of cargo along the tray will be significant (although vibration contributes to a reduction in the resistance to movement of cargo through the tray), which leads to a decrease in the speed of movement of the material at the outlet from the loading tray and if the velocity vector of the traffic flow 5 does not match the belt speed vector, intense wear will occur tapes.

Целью изобретени вл етс уменьшение сопротивлени перемещению груза по лотку путем придани лотку эллиптической траектории колебани .The aim of the invention is to reduce the resistance to movement of the load on the tray by making the tray elliptical oscillation trajectory.

Указанна цель достигаетс тем, что верхн часть лотка снабжена направл ющим механизмом, а лоток выполнен с возможностью перемещени по опорным элементам. Направл ющий механизм выполнен в виде копира и взаимодействующего с ним ролика , закрепленного на лотке. Кроме того, опорные элементы выполнены в виде роликов.This goal is achieved by the fact that the upper part of the tray is provided with a guiding mechanism, and the tray is adapted to move along the supporting elements. The guide mechanism is made in the form of a copier and a roller interacting with it, mounted on a tray. In addition, the supporting elements are made in the form of rollers.

Claims

The loading device for loading the belt conveyor includes an inclined tray 1 connected to the frame 2 by elastic supports 3, which are made in the form of the body 4 with rubber liners 5 fixed to it, between which the support fixed to the tray 6 is clamped. The upper part of the tray has a guide mechanism for providing a predetermined path of movement of the tray, made in the form of a copier 7 mounted on the frame and a roller 8 interacting with it fixed on the tray. The design parameters of the guiding mechanism (angle y, copier curvature, installation location on the tray, communication with the tray com) are selected depending on the operating conditions of the device (for example, the traffic flow). To ensure free movement of tray 1 along its longitudinal axis, its lower part is mounted for movement along support elements made in the form of roller 9. The lateral movement of the lower part of the tray is limited by stops 10. Another embodiment of the support element can be realized by mounting the rollers on bottom of the tray. In this case, to reduce the transmission of vibration from the tray to the frame, elastic elements can be installed between the supports 11 of the axis 12 of the roller 9 and the frame. The device works as follows. Under the action of dynamic loads from the material entering the tray, transverse oscillations of the tray occur. Due to the interaction of the roller 8 with the cam 7 during transverse movements, the tray is also moved along its longitudinal axis. Rubber liners 5 have a cylindrical shape and have the same shear (stiffness) resistance in all directions. Consequently, along with transverse vibrations, longitudinal vibrations of the tray arise, i.e., the elliptical vibrations of the tray are resulting, which, according to the theory of vibro-transport, significantly increases the speed of movement of the load and reduces the coefficient of friction of the load on the tray, increasing the service life of the latter. Such an embodiment of the device will reduce the wear of the belt and the likelihood of the stitching of the loading device, which will increase the reliability of the conveyor. Claim 1. Device for loading a belt conveyor, including an inclined tray, the upper part of which is fixed on elastic supports, and the lower part is located on supporting elements, characterized in that, in order to reduce the resistance to movement of cargo on the tray by giving the tray an elliptical oscillation trajectory, the upper a portion of the tray is provided with a guide mechanism, and the tray is adapted to move along support elements. 2. The device according to claim 1, characterized by the heme, that the guiding mechanism is made in the form of a copier and a roller interacting with it, mounted on a tray. 3.
