Feeding device of building concrete

Abstract

The invention discloses a feeding device of building concrete, and belongs to the technical field of raw material transporting. The feeding device of the building concrete includes a material inlet bin and a material conveying pipe body communicating with the material inlet bin. The feeding device is characterized in that a baffle is hinged to the top of the inner side of the material inlet bin, afirst connecting rod is hinged to the bottom of the baffle, a second connecting rod is hinged to the first connecting rod, an elastic hinging sheet is fixed to an included angle between the second connecting rod and the first connecting rod, one part of the elastic hinging sheet is fixed to the second connecting rod, the other part of the elastic hinging sheet is fixed to the first connecting sheet to form an elastic buffering assembly, a spring is mounted on the second connecting rod, and the other end of the spring is fixed to the inner wall of the material inlet bin. According to the feeding device of the building concrete, the material inlet bin is sealed, contact between the concrete and air is reduced, the solidified rate of the concrete is lowered, and waste of resources is reduced.

Description

technical field [0001] The invention relates to a feeding device, in particular to a feeding device for building concrete, and belongs to the technical field of raw material transportation. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. , Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture, and the hard state after hardening, that is, hardened concrete or concrete. The concrete strength grade is based on the cubic compressive strength standard According to the value division, the strength grade of ordinary concrete in China is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80.

Problems solved by technology

[0003] At present, the concrete used in the construction site is often exposed to the air when it is transported, so that the concrete is easy to solidify, and the current conveying device is conveyed at the external temperature, and the change of the external temperature further accelerates the concrete condensation on the conveying device. In addition, in the prior art, for example, the patent documents CN205238307U and CN205766846U adopt inner cylinder and outer cylinder structures, and the outer cylinder is provided with heating equipment, and cooperate with lifting and spiral structures to realize mixing of concrete, but for concrete The heating intensity adjustment is not flexible enough, and it is only realized by heating time or controlling the heating current. Therefore, it is not easy to promote products designed by the same manufacturer in different regions, especially in different regions with large temperature differences.
