Description

[0002] A coal feeder is a mechanical device that can accurately adjust the amount of coal fed to a coal mill according to load requirements. The belt skirt structure of a coal feeder usually refers to the part of the belt conveyor equipment used in the conveying system. The belt skirt structure is designed to prevent material overflow and reduce dust flying to keep the working environment clean and ensure the safe and efficient operation of the conveying system.
[0003] When the existing belt skirt is in use, the lower end is mostly used to support the conveyor belt through one or more rollers, but the lower ends of the skirts on both sides lack a certain supporting structure. After long-term use, the skirts may collapse under the action of gravity, thereby damaging the shielding effect of the skirts when conveying coal, causing coal leakage. When urgent production tasks occur, sometimes in order to improve production efficiency, the raw coal supply of the coal feeder may be increased. At this time, the height of the conveying coal seam will increase, and the original skirt height may not be able to provide good shielding for the coal. For this reason, a coal feeder belt skirt structure is proposed to solve the above-mentioned problems. Utility Model Content

When the raw coal supply of the coal feeder needs to be increased, a heightening baffle can be installed inside the slot, and the circular clamping block is pushed to abut against the heightening baffle by rotating the fixing screw to fix the heightening baffle. The position of the heightening baffle is adjusted by using the first threaded rod and the second threaded rod, so that the heightening baffle is close to the inner side of the skirt body, thereby temporarily increasing the limit height on both sides of the conveyor belt, thereby better shielding the coal.
