Aggregate transition bin for mortar stone wrapping method and feeding and discharging method thereof

Abstract

The invention provides an aggregate transition bin for a mortar stone wrapping method. The whole aggregate transition bin acts on a pressure sensor, and the weight of aggregate in the aggregate transition bin is read through cooperation of the pressure sensor and control software. When the aggregate transition bin is used for feeding, sand is firstly put into the bin, stones are then put into theupper part of the sand, and up-down separation of stones and sand is realized; during discharging, the feeding amount of part of sand is set through control software, then a discharging door is controlled to be opened for discharging, the sand, cement and water are pre-stirred firstly, then a small amount of remaining sand and stones are fed and fully mixed and stirred, and the discharging methodmeets the sand and stone secondary feeding process in a mortar stone wrapping method. The transformation of the aggregate transition bin does not change the structure of the aggregate bin, the aggregate transition bin can be applied to secondary feeding and can also be applied to the original process, the structure is simple, the operation is convenient, the transportation period is shortened, andthe working efficiency of the mortar stone wrapping process is improved.

Description

technical field [0001] The invention relates to the field of concrete mixing equipment, in particular to an aggregate transition bin used in the mortar-wrapped stone method and a material feeding and discharging method thereof. Background technique [0002] The traditional concrete mixing process is to put stones, sand, cement, water and admixtures and other raw materials into the mixer for mixing. After mixing evenly, it is qualified concrete. With the continuous development of the mixing process, a batch feeding mixing process has emerged, such as the cement-wrapped sand method, the cement-wrapped stone method and the mortar-wrapped stone method. Under the premise of material resources, the strength of concrete can be increased by 10-20%, and under the premise of constant concrete strength, 5%-10% of cement can be saved, effectively reducing the cost of concrete production. Among them, the mortar-wrapped stone method has developed rapidly due to the advantages of fewer ti...
