Building material conveying device

Abstract

The invention belongs to the technical field of cement dust removal equipment, and particularly relates to a building material conveying device which comprises a body, a conveying belt and a feeding hopper. The feeding hopper is arranged at the end of the conveying belt, and an opening is formed in the side, close to the conveying belt, of the feeding hopper. A pair of buffer curtains are fixedly connected to the corresponding positions, located on the two sides of the conveying belt, of the inner wall of the feeding hopper, and the tops and the opening sides of the buffer curtains are fixedly connected with the inner wall of the feeding hopper. The inner wall of the feed hopper at the bottom of the buffer curtain is fixedly connected with an elastic air bag through a support plate, and a valve hole communicating with the air bag is formed in the middle of the support plate. The buffering curtains fixedly connected in the feeding hopper are matched with the air bag, when a cement bag falls on the buffering curtains, the air bag is pressed and then exhausts air outwards through the valve hole, meanwhile, the buffering curtains on the two sides wrap the cement bag, the speed of the cement bag approaching the conveying belt is reduced, cement overflowing is reduced, then the impact force between the cement bag and the conveying belt is reduced, and flying dust pollution and cement overflow are reduced.

Description

Technical field [0001] The present invention belongs to the technical field of cement dust removal equipment, and is specifically a conveying device for building materials. Background technique [0002] When the cement is shipped, it is often used in a bag, and the plastic woven bag is used for packaging. It is suitable for a small number of private families. It is convenient to store, but add packaging costs; cement directly into the special bulk car or train, pull to buildings The construction site is reiled into the storage steel warehouse, called the bulk for large-scale engineering, saving the woven bag. [0003] Some technical solutions for cement dust removal equipment have also emerged in the prior art, such as a Chinese patent disclosed in the application No. 2019219983436, which discloses a dust removal device of a cement loading, including disposing ends of the conveyor. The present invention includes a dust tube of a square tube structure, a dust pipe abuts the lower ...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, the packaging bag for packing cement in the prior art is a woven bag, and there are many fine and close gaps on the woven bag, and the cement is easy to seep out of the packaging bag, resulting in more adhesives attached to the packaging bag. When the cement powder is transported through the conveying device, there is a certain height difference when the bagged cement falls on the conveyor belt, which makes the cement bag contact with the conveyor belt to form a large impact force, increasing the cement bag. The amount of cement spilled and seeped, while increasing dust, increasing environmental pollution and waste of cement, the invention proposes a conveying device for building materials
