Batching system of concrete aggregate

Abstract

The invention provides a batching system of a concrete aggregate, which belongs to the technical field of construction. The batching system of the concrete aggregate comprises a receiving and distributing device, a weighing and unloading mechanism and a mixer. The end of a two-stage conveyor belt is located above a receiving barrel. The distributing hopper is rotatably connected to the lower end of the receiving barrel. The housing of a first stepping motor is fixed on the receiving barrel. A discharge end of the distributing hopper is inclined to the side deviating from the axis of the receiving barrel. The distributing hopper is provided with a transmission gear ring. A driving gear is fixedly arranged on an output shaft of the first stepping motor, and the driving gear meshes with the transmission ring gear. A plurality of temporary storage cavities are arranged in a sub-packing tank. The distributing hopper can be rotated to make the discharge end of a discharge hopper located above each temporary storage cavity. The weighing and unloading mechanism comprises a plurality of suspended weighing devices corresponding to the temporary storage cavity one-to-one. The suspended weighing devices can send the materials in the corresponding temporary storage cavities into the mixer according to the amount. The batching system of a concrete aggregate has the advantages of being able to divide different aggregates and the like.

Description

Technical field [0001] The invention belongs to the field of construction technology and relates to a batching system of concrete aggregates. Background technique [0002] Concrete is a building material formed by mixing various aggregates, additives and other materials. In order to reduce the transportation process and improve efficiency, it is usually necessary to transport all kinds of materials to a designated height or a designated position, and then mix them. For the transportation of different specifications and types of aggregates, if multiple conveyor lines are used, it will greatly increase the cost and management difficulty; the principle of zero waiting for the mixer requires that all aggregates be transported to a designated location for storage, and then divided into batches It is mixed to the mixer at the same time, which requires the conveyor line to transport different aggregates separately, which requires a higher tension on the conveyor belt. This is because di...

Problems solved by technology

[0002] Concrete is a building material formed by stirring and mixing various aggregates, additives and other materials. In order to reduce the transportation process and improve efficiency, it is usually necessary to transport various materials to a specified height or a specified location, and then mix them. Due to the many For the transportation of different specifications and types of aggregates, if multiple conveying lines are used, the cost and management difficulty will be greatly increased; the principle of zero waiting for the mixer needs to transport all aggregates to the designated location for storage, and then divide them into batches Mixing to the mixer for the first time, which requires the conveying line to convey different aggregates separately, and the separate conveying requires high tension of the conveyor belt, which is due to the different aggregates on the same conveyor belt. The quantity is almost the same, but the density is quite different, which leads to different requirements for the tension of the conveyor belt when transporting different materials. There are corresponding requirements for the temporary storage, distribution, and weighing of materials when transporting aggregates separately. It will increase the difficulty, but if the transmission distance is long and multiple transmission lines are used, the cost of the transmission line and the occupied area of ​​the site will be greatly increased
