For rugged areas such as deep canyons and steep slopes, due to the high silo entry strength and the limited vertical transportation of concrete, the main concrete entry methods include vacuum chute entry and negative pressure chute entry, which are prone to aggregate separation and secondary crushing of aggregates.

[0003] A Chinese patent with publication number CN115492116B discloses a concrete conveying system, including a belt conveyor, a descender for receiving materials conveyed by the belt conveyor, and a placing machine for receiving materials conveyed by the descender, wherein the descender includes: a support frame, which includes a vertical conveying channel, and the conveying channel includes two branch channels arranged adjacent to each other horizontally; multiple groups of material transfer components, each material transfer component includes a material transfer box slidably arranged in two branch channels of a corresponding conveying unit, and a switch cover is arranged at the bottom end of each material transfer box for moving up to open / down to close; a hopper, which is arranged at the top of the support frame and is used to receive materials conveyed by the belt conveyor and introduce them into the corresponding material transfer box.

[0004] The concrete delivery system in the prior art has a long concrete production cycle and is highly dependent on manual labor during the production process, which increases labor costs and human resources. The mix ratio error of manual concrete is large, which reduces the strength and durability of the concrete. At the same time, it is easy to cause material loss due to human errors, thereby increasing production costs. Summary of the invention

The automated system can quickly complete batching and conveying, significantly shorten the concrete production cycle, reduce dependence on manual labor through automation, reduce labor costs and human resource arrangements, and at the same time, the automated system uses precise weighing sensors to ensure that each component is batched according to a set ratio. Accurate proportioning can improve the strength and durability of concrete and ensure the stability of product quality, so as to solve the technical problems of the existing concrete conveying system, such as long concrete production cycle, high degree of dependence on manual labor, large error in manual concrete proportioning, and high production cost.

[0006] To achieve the above object, the present invention adopts the following technical solution:
