Device for composting concrete aggregate with large particle diameter

Abstract

Device for composting concrete aggregate with large particle diameter comprises a tower, a steel upright column and a backstay cable, wherein the steel upright column is provided with a hoist workbench, two hinge supports are arranged on the hoist workbench, and a movable cantilever truss girder is connected with the hinge supports via axle pins; a hoist is equipped on the hoist workbench, a sealing-tape machine is arranged on the movable cantilever truss girder, and a steel wire rope of the hoist is connected with the movable cantilever truss girder via two assembly pulleys. Compared with the current scheme of adopting a stocker, the device provided by the invention saves the cost of purchasing stocker equipment, and reduces construction land occupation and civil engineering expense; and compared with the scheme of adopting a sealing-tape machine for blanking and stockpiling at fixed point, the device of the invention can maximally avoid second fragmentation of the aggregate with large particle diameter in stockpiling, and reduces the undersize index of the particle diameter aggregate by 8% to 18%, at the same time, guarantees continuous aggregate grading, avoids aggregate separation, and solves concrete separation problem caused by unreasonable particle diameter of coarse aggregate, so as to reach the quality requirement of concrete aggregate.

Description

technical field [0001] The invention relates to a novel concrete large-diameter aggregate stockpiling device, which can effectively prevent secondary crushing and gradation separation of aggregates during the stockpiling process during the use of a concrete gravel processing system. It is especially suitable for conveying and stockpiling aggregate boulders (40-80mm) and extra large stones (80-150mm) in the concrete sand and gravel aggregate processing system in the hydraulic construction industry. Background technique [0002] The large stone (40-80mm) and extra large stone (80-150mm) aggregates required for the current hydraulic concrete construction project are usually piled up by belt conveyor at fixed points after being discharged from the screening building. During the storage process, aggregates are often broken and segregated to varying degrees. After the aggregate is crushed and segregated, the original gradation of the concrete is destroyed, and because the crushin...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a stacking device for concrete large-size aggregates. When the device transports large-size finished aggregates, the belt conveyor can effectively control the stacking height and carry out stacking to prevent large The secondary crushing of the particle size aggregate during the stockpiling process can effectively control the secondary crushing of the large particle size aggregate during the stockpiling process. Avoid aggregate separation and solve the problem of concrete segregation caused by unreasonable particle size of coarse aggregate to ensure the quality requirements of concrete aggregate
