Description

Technical Field

[0001] This utility model relates to the technical field of coal mine belt conveyors, specifically a dustproof structure for a coal mine belt conveyor. Background Technology

[0002] Coal is a carbonized fossil mineral formed from the remains of ancient plants buried underground and subjected to pressure and temperature conditions isolated from air by the Earth's crust. It is a black solid mineral composed of elements such as carbon, hydrogen, oxygen, and nitrogen, and is mainly mined by humans for use as fuel.

[0003] Application number "CN202323223641.7" discloses a dustproof structure for a coal mine belt conveyor, relating to the technical field of coal mine belt conveyors. It includes a support platform, a dustproof cover, and water pipes. A belt conveyor is mounted on the support platform. A pair of fixed plates are fixed to the bottom of the support platform, and a water tank is fixed between the fixed plates. A pair of side plates are fixed to the support platform, each with a U-shaped strip. Multiple rotating wheels are mounted on each U-shaped strip. The dustproof cover is slidably connected to the U-shaped strips. A water pump is fixed to the dustproof cover, and a round rod is fixed inside the dustproof cover. This invention utilizes the combined use of an atomizing nozzle and a dustproof cover. When dust is generated during coal mine transportation, the atomizing nozzle removes dust from the air, and the dust generated by vibration is prevented from spreading through the dustproof cover. The crossbar and brush work together to clean coal slag adhering to the belt through friction between the brush and the belt, reducing belt wear.

[0004] When the above-mentioned equipment is in use, small stones splashed from the outside may collide with the dust cover due to the influence of the operating environment, which may cause damage to the dust cover. The dust cover is connected to the equipment, and it is inconvenient to replace it when it is damaged. When the dust cover is damaged, coal ash can easily flow out from the gap. In addition, the tilt angle of the feed chute of the above-mentioned equipment cannot be adjusted, which means that it cannot be adjusted according to the actual situation, reducing the practicality of the equipment during use.
