Description

FIELD OF THE INVENTION

The invention relates to mechanical equipment for conveying material. In particular, the invention relates to a belt conveying device with crushing and dust-proof functions for agglomerated finely divided materials.

BACKGROUND

As is well known, in order to better mix a variety of materials, the method often used is to first crush the materials and then mix them, but the finely divided materials are prone to agglomeration due to moisture environment during storage. Agglomerate finely divided materials not only affect the mixing effect of materials, but also increase the chance of machine failure and damage caused by sudden changes in load on the mixing machine.

When the finely divided materials are transported on the conveying equipment, the dust is easily generated due to the vibration of the conveying equipment, which jeopardizes the health of the workers. In addition, the finely divided materials are easily attached to the conveyor belt, and the materials may fall into the conveying device with the rotation of the conveyor belt, which leads to machine failure.

However, the existing conveying devices generally do not have elements for crushing the agglomerated finely divided materials, nor elements for cleaning the materials adhered on the conveyor belt. The existing dust-proof elements of conveying devices are generally simple dust cover. There is not much dust-proof effect for two workers standing on the positions where the feeding end and the discharging end of the conveying devices are present.
