Description

A dust-proof industrial and mining conveyor belt

Technical field

The invention relates to the technical field of industrial and mining production, and in particular, to a dust-proof industrial and mining conveyor belt.

Background technique

Industrial and mining production refers to the mining industry. Mining refers to the processing of minerals by cutting or hammering ores into small pieces or granules through heavy machinery to facilitate subsequent use and processing. When carrying out industrial and mining production, industrial and mining Conveying is an indispensable step.

Existing dust-proof industrial and mining conveyor belts use transmission rollers inside the conveyor belt. A motor is installed on one side of the transmission roller. The motor drives the transmission roller to rotate and then transport the ore. In order to prevent dust from flying out, a dust cover is required to prevent dust from flying out. The dust cover is fixed at both ends above the conveyor belt through bolts, so that the dust cover blocks the dust on the top of the conveyor belt and prevents flying dust from affecting the operator's body.

In the existing technology, dust-proof industrial and mining conveyor belts use bolts to fix the dust-proof cover, which can easily lead to different sizes of transported ores, thus requiring bolts to adjust the height. In addition, under long-term use, the dust-proof cover will be worn out. The inner wall is inconvenient to clean, and the industrial and mining debris and dust on the surface of the conveyor belt adhere to the surface of the conveyor belt. When the site needs to be changed, the dust cover needs to be disassembled. During disassembly, the dust above the dust cover is not cleaned, which is harmful to the operator. It affects the body, so when the conveyor belt is transported at one end, it needs to be shut down to clean the dust-proof upper cover. Therefore, a dust-proof industrial and mining conveyor belt is proposed to solve the above problems.
