Concrete production system

Abstract

The invention relates to a concrete production system. The concrete production system comprises a storage device, a feeding device, a belt conveyor and a mixing drum which are arranged in sequence, wherein the belt conveyor comprises a rack, a plurality of rotating rollers rotationally connected to the rack, a conveying belt winding around the rotating rollers and a speed reducer connected with one rotating roller, two abutting rollers are rotationally connected to the portion, located on the lower side of the conveying belt, of the rack, a tension roller is in vertical sliding connection with the portion, located between the two abutting rollers, of the rack, and the tension roller abuts against the inner side wall of the conveying belt; and a transmission part for driving the tension roller to slide is also arranged on the rack. The transmission part is used for driving the tension roller to extrude the conveying belt, the friction force between the conveying belt and the rotating rollers is increased, efficient transmission work on the conveying belt in the rotating process of the rotating rollers is guaranteed, and therefore, the normal conveying effect of the conveying belt for raw materials is guaranteed.

Description

technical field [0001] The present application relates to the field of concrete production, in particular to a concrete production system. 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. [0003] The Chinese patent with the notification number CN205438900U discloses an improved concrete production system, including a support frame, a material storage device, a feeding device, a screw conveyor, a scraper type feeding belt conveyor, a PLC controller, a support, a mixing drum, and a feeder. Feeding device, water inlet device and unloading mechanism; feeding device includes sand and gravel feeding device, auxiliary material feeding device and cement feeding device, sand and gravel feeding device includes sand and gravel feeder, horizontal conveyo...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that because the mixing drum of the existing mixing station is generally large, and when the mixing drum is discharged, the vehicle is generally under the discharge port of the mixing drum, and the concrete is directly unloaded on the vehicle, and then It is transported to the construction site by vehicles, so the height of the mixing drum is generally high; therefore, the scraper type feeding belt conveyor needs to be inclined to transport the raw materials to the mixing drum, and at the same time, the scraper type feeding belt conveyor needs a long length to meet its work. Therefore, the belt on the scraper type feeding belt conveyor is correspondingly longer, and during the long-term transportation of the belt, because the material itself is made of rubber, the belt is easy to gradually lose its elastic effect and loosen, which affects the transportation of concrete raw materials
