Scraping device for conveying of emulsion explosives

Abstract

The invention discloses a scraping device for conveying of emulsion explosives. The scraping device comprises a belt conveyor. A scraping mechanism located above a conveyor belt is arranged on a rackof the belt conveyor. The scraping mechanism is mainly composed of a rubber plate bracket and a rubber plate body. The rubber plate bracket is provided with a clamping groove for embedment of the rubber plate body. The rubber plate bracket is connected to the position above the conveyor belt of the belt conveyor. The root of the rubber plate body is embedded and fixed into the clamping groove of the rubber plate bracket. The front portion of the rubber plate body extends downwards towards the conveyor belt of the belt conveyor. According to the conveying particularity of the emulsion explosives, the rubber plate body of the scraping mechanism on the belt conveyor is embedded and fixed into the clamping groove of the rubber plate bracket through the clamping groove structure. The scraping device is simple in structure, convenient to mount and demount and steady and firm in structure, and the service life of the scraping device can be substantially prolonged. Accordingly, the maintenancefrequency and maintenance cost are reduced, and meanwhile, the scraping device is convenient and easy to clean and high in practicality.

Description

technical field [0001] The invention relates to a belt conveyor used for conveying emulsion explosive matrix during production, in particular to a scraping device for conveying emulsion explosive. Background technique [0002] Most of the production processes of emulsion explosives are connected by belt conveyors, so that the matrix of emulsion explosives is conveyed sequentially between each process until the finished product is packaged. During the conveying process of the emulsion explosive matrix, due to the various processing procedures and connection inversion, most of the matrix conveyed on each belt conveyor is piled. A scraping device is installed on the conveyor, and the scraping device will spread the piled matrix conveyed on the conveyor belt of the belt conveyor to a substantially equal thickness; or, in order to facilitate the transportation of the emulsion explosive matrix by the belt conveyor , It is necessary to set up a scraping device on the belt conveyor...

AI Technical Summary

Problems solved by technology

[0005] 1. The mechanical screws connected and fixed between the rubber plate frame and the rubber plate body are easy to fall off due to mechanical fatigue. On the one hand, it will affect the stability and assembly accuracy of the rubber plate body, and on the other hand, the fallen mechanical screws are easy to fall into the emulsion explosive There are certain potential safety hazards in the charging machine, which makes the scraping mechanism of the scraping device have a short service life, high maintenance frequency and high cost; what's more, the loading and unloading of the scraping mechanism with this structure on the belt conveyor The operation is cumbersome, and convenient, easy and easy cleaning cannot be realized;

[0006] 2. The scraping mechanism is usually assembled on the frame of the belt conveyor with a fixed structure. The height of the rubber plate body relative to the conveyor belt of the belt conveyor cannot be adjusted flexibly, accurately and reliably, and the flexibility in use poor sex
