54) УКРЫТИЕ УЗЛА ПЕРЕГРУЗКИ КОНВЕЙЕРОВ54) COVERING THE CONVEYOR OVERLOAD UNIT

1one

Изобретение относитс к транспорту, а именно к укрыти м узла перегрузки конвейеров .The invention relates to a vehicle, namely shelters for an overloading unit of conveyors.

Известно укрытие узла перегрузки конвейеров , включающее верхний и нижний бункеры , гибкие элементы, жестко прикрепленные к верхнему бункеру одной стороной и свободно свисающие с противоположной стороны , чем обеспечиваетс возможность вращени одного из бункеров 1.The cover of the conveyor overload assembly is known, including upper and lower bunkers, flexible elements rigidly attached to the upper bunker on one side and hanging freely from the opposite side, thus allowing rotation of one of the bins 1.

Недостатком такого укрыти вл етс то, что оно не обеспечивает герметизации в перегрузочных узлах, где оси вращени подающего (верхнего) и принимающего (нижнего) бункеров не совпадают, в результате чего не исключаетс периодическое пылеобразование. The disadvantage of this cover is that it does not provide sealing in the transfer points, where the axes of rotation of the feed (upper) and receiving (bottom) bins do not coincide, as a result of which periodic dusting is not excluded.

Конструкции перегрузочных узлов, бункеры которых посто нно перемещаютс по отношению друг к другу в осевом и поперечном направлени х, примен ютс на полноповоротных горнотранспортных мащинах непрерывного действи (роторные экскаваторы , промежуточные перегружатели, отвалообразователи).Constructions of transshipment units, the bunkers of which are constantly moving relative to each other in axial and transverse directions, are used on full-circle continuous-transport mining machinery (rotary excavators, intermediate loading cranes, spreaders).

Наиболее близким к изобретению по технической сущности и достигаемому эффекту вл етс перекрытие узла перегрузки конвейеров, включающее верхний и нижний бункеры, аспирационный элемент, упорный подшипник с верхней и нижней обоймами , уплотнительное кольцо 2.Closest to the invention in its technical essence and the achieved effect is the overlapping of the conveyor overloading unit, including the upper and lower bins, the aspiration element, the thrust bearing with the upper and lower collars, the sealing ring 2.

5Недостатком известного устройства вл етс то, что аспирационный элемент и уплонительное кольцо расположены по отнощению к нижнему бункеру с зазором, в результате чего нарущаетс герметичность,5 The disadvantage of the known device is that the aspiration element and the sealing ring are located relative to the bottom bunker with a gap, as a result of which the tightness is impaired,

,0 возникает пылеобразование, которое увеличиваетс при перегрузке на подвижных относительно друг друга конвейерах., 0 dust formation occurs, which increases with overload on conveyors moving relative to each other.

Целью изобретени вл етс уменьшение пылеобразовани при перегрузке на подвижных относительно друг друга конвейерах .The aim of the invention is to reduce dust generation during overload on conveyors moving relative to each other.

Claims

This goal is achieved by the fact that the shelter of the conveyor overload assembly, including the upper and lower bins, the post element, the thrust bearing with the upper and lower collars, the sealing ring, is equipped with a face plate installed in the lower part of the upper bunker, on which the lower cage of the thrust bearing is located, and the upper race of the thrust bearing is connected to the sealing ring and the suction element connected to the lower hopper by means of an elastic sleeve. FIG. 1 shows the assembly of the conveyors, general view; in fig. 2 — node I in FIG. 1. Shelter includes upper 1 and lower 2 bunkers, aspiration element 3, which is attached to the sealing ring 4, which is fixed to the upper holder of the bearing 5 with brackets 6. Lower holder 7 of the bearing is fixed to the plate 8. Between the lower holder and the sealing ring is installed packing 9. The aspiration element is connected with the lower hopper by means of an elastic sleeve 10. The device operates as follows. When the conveyor 11 rotates with the hopper 2 around its axis, the elastic sleeve 10 and the aspiration element 3 are the rotational moment is driven through the ring 4 to the upper holder of the bearing 5, ensuring reliable tightness. Thus, dust formation from under the cover is prevented, the efficiency of dust suction is increased. Such an embodiment of the cover reduces the dust formation by overloading on movable relative to each other conveyors. Invention Shelter of conveyor overloading unit, including upper and lower bunkers, aspiration element, thrust bearing with upper and lower collars, sealing ring, characterized in that, in order to reduce dust formation during overload on conveyors moving relative to each other, parts of the upper bunker faceplate, on which the lower holder of the thrust bearing is located, and the upper holder of the thrust bearing is connected to the sealing ring and the suction element connected to the bottom hopper by means of an elastic sleeve.
