Material conveying device for concrete production

Abstract

The invention provides a material conveying device for concrete production, and belongs to the technical field of concrete production. The material conveying device comprises a conveying mechanism, asupporting tensioning mechanism, a discharging mechanism, a material scraping mechanism and a cleaning mechanism, wherein a conveying belt of the conveying mechanism winds around a first conveying roller, a second conveying roller, a second conveying supporting guide roller, a conveying belt outward-turning roller and a first conveying supporting guide roller; supporting tensioning assemblies of the supporting tensioning mechanism are uniformly distributed on a supporting tensioning frame; the lower end of a material scraping swing rod of the material scraping mechanism is hinged with a secondconveying supporting guide roller frame through a material scraping swing rod pin shaft; a material scraping tongue is arranged at the upper end of the material scraping swing rod; the cleaning mechanism comprises a cleaning assembly and a water circulation assembly; and cleaning brushes are uniformly distributed on cleaning rollers of the cleaning assembly. According to the material conveying device, the stable conveying of concrete can be ensured, the concrete is prevented from being condensed on the conveying belt; and the conveying belt is good in supporting and tensioning effect and longin service life.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a material delivery device for concrete production. Background technique [0002] 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 appropriate proportions, 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; the hard state after hardening, that is, hardened concrete or concrete. At present, after a concrete manufacturer completes concrete production, it is generally directly transferred to a concrete transport vehicle through a material transfer device, and the concrete transport vehicle directly transports the concrete to the construction site. At present, the common conveying devices are gener...

Problems solved by technology

However, because the concrete is easy to harden, the concrete often condenses on the conveyor belt, causing the concrete on the conveyor belt to accumulate and thicken, which seriously affects the transmission of the conveyor belt. The service life of the conveyor belt is very short, and the conveyor belt often needs to be replaced.

Furthermore, the quality of the concrete is relatively large, and the pressure on the conveyor belt during the transmission process is relatively high, which can easily cause pressure damage to the conveyor belt or cause the conveyor belt to lose its elasticity, resulting in failure or inability to tension the conveyor belt, seriously affecting the transmission of concrete.
