Belt conveyor capable of uniformly distribution materials in large range

Abstract

The invention discloses a belt conveyor capable of uniformly distribution materials in a wide range. The belt conveyor comprises two longitudinal moving rails, a main conveying belt conveyor and a material distribution belt conveyor, wherein the main conveying belt conveyor is provided with a main belt for forming a circulation loop, the main belt is bent by two guide wheels to form a S-shaped loop, and the two guide wheels are fixedly arranged on a material distribution trolley; the material distribution belt conveyor is fixed at the lower end of the material distribution trolley, the material distribution belt moves forwards and backwards along with front-back movements of the material distribution trolley along the longitudinal moving rails; and the material distribution trolley can move forwards and backwards along the longitudinal movement rails, so as to drive the two guide wheels mounted on the material distribution trolley to move. The belt conveyor provided by the invention has a longitudinal and transverse moving distribution material belt conveyor, and theoretically can carry out fixed-point distribution material on almost all positions in a material bin, can be uniformly stacked in a large-area manner at one time, and a loading machine or an excavator does not need to be used for carrying out secondary stacking on gravel materials (or other bulk materials) after warehousing.

Description

technical field [0001] The invention relates to the field of belt conveyors. More specifically, the present invention relates to a belt conveyor capable of uniformly distributing material over a large area. Background technique [0002] Concrete mixing plants need to set up sand and gravel silos to stack and store sand and gravel materials. Usually, there are many types of concrete in a project, so different sand and gravel materials are required to meet the mix ratio. For a certain project, there are as few as 3 to 4 types of sand and gravel materials, and as many as 7 to 8 types, which are arranged in different compartments. [0003] At present, there are two ways for sand and gravel to be put into the warehouse. One is to transport the sand and gravel to the warehouse by dump truck, directly unload the material to the corresponding compartment, and then use a loader or excavator to stack the sand and gravel for leveling; the other is to use Conventional belt conveyors a...

Problems solved by technology

[0004] If the belt conveyor is used for warehousing, the material distribution trolley is generally used to directly distribute the aggregate from the main belt into the silo. Recently, another method has emerged. A very short material distribution belt conveyor is installed under the material distribution trolley. The material distribution on both sides of the main belt conveyor can expand the material distribution range to a certain extent, but because the material distribution belt conveyor is fixed horizontally, it is still difficult to cover the material distribution range when the silo is wide, and a loader or excavator is still required. secondary stacking
