Description

(54) ВИНТОВОЙ КОНВЕЙЕР(54) SCREW CONVEYOR

1one

изобретение относитс к подъемно-транспортному машиностроению, в частности к винтовым конвейерам дл сыпучи.ч .материалов .This invention relates to a lifting and transport engineering, in particular to screw conveyors for bulk materials.

известны винтовые конвейеры, имеющие промежуточную опору в виде короткого отрезка винта, винтовые поверхности которого перекрываютс с винтовыми повер.хност ми стыкуемых секций шнека, и желоба U-образной формы, установленного на упругих элементах между коротким отрезком винта и корпусо.м винтового конвейера в нижней части с возможностью регулировани его по высоте 1 .screw conveyors are known, which have an intermediate support in the form of a short screw segment, whose screw surfaces overlap with screw surfaces of the screw auger sections to be joined, and are U-shaped grooves mounted on elastic elements between the short screw segment and the screw conveyor belt at the bottom parts with adjustable height 1.

Недостатками такой опоры вл ютс невозможность г рименени ее в быстроходных винтовых конвейерах, интенсивный износ кромки короткого отрезка винта, ненадежность работы U-образного желоба из-за возможности попадани материала между желобом и корпусом винта.The disadvantages of such a support are the impossibility of rotating it in high-speed screw conveyors, the intense wear of the edge of a short section of a screw, and the unreliability of the operation of the U-shaped groove due to the possibility of material falling between the groove and the screw body.

Наиболее близким к изобретению вл етс винтовой конвейер, включающий кожух с размешенным в нем винтом, промежуточные опоры с подшипниками и привод 2 .Closest to the invention is a screw conveyor comprising a casing with a screw disposed therein, intermediate bearings with bearings and a drive 2.

Недостатком известного конвейера вл етс применение подшипника и шнека больших диаметров, и, в св зи с этим, удорожание узла. Кроме того, конструкци опор позвол ет примен ть их в ко,пичестве не меньше трех штук в одном конвейере, что не оправдано при небольших длинах конвейера .A disadvantage of the known conveyor is the use of a bearing and a screw of large diameters, and, in connection with this, an increase in the cost of the assembly. In addition, the design of the supports allows them to be used in coke, with at least three pieces in one conveyor, which is not justified for small conveyor lengths.

Приварка опорных втулок к лопаст м щнека в различных точках приводит к возникновению знакопеременных нагрузок на шнек, что отрицательно сказываетс на сроке его службы.The welding of the bearing sleeves to the blade of the screw at various points leads to alternating loads on the screw, which adversely affects its service life.

Целью изобретени вл етс повышение производительности конвейера при большой длине транспортировани пылевидных и зернистых грузов.The aim of the invention is to increase the productivity of the conveyor with a large length of transportation of pulverized and granular goods.

Указанна цель достигаетс тем, что вThis goal is achieved by the fact that
