Description

Technical Field

[0001] The utility model relates to the technical field of material feeding, in particular to a belt material feeding regulating mechanism. Background Art

[0002] Common links of loose coal belt conveyor Figure 4 As shown: First, coal is dropped from the upper end of the belt conveyor line to load the materials; then the coal is dropped through the coal loading device to the belt conveyor line; then the belt conveyor line carries the loose coal and materials to the production demand link for use;

[0003] The incorrect coal drop point is one of the main factors that affect the deviation of the belt during operation. Due to the different physical properties of coal on the belt due to changes in coal type and moisture content, the amount of moisture in the loose coal, the size of the block condensation or looseness, the scaling condition of the lower end outlet of the drop feeding device and other factors, it will eventually cause the center of gravity of the loose coal to accumulate on the A side or B side of the belt; in this way, as the belt conveyor line continuously runs in the feeding direction, the gravity center of gravity will deviate the belt as a whole to the A or B side by a small amount. The result of the deviation of the belt carrying loose coal and bulk materials is first of all a decrease in transportation efficiency; the deviation of loose coal and bulk materials causes the edge of the accumulation to overflow and fall out of the belt carrying range, increasing the on-site management and maintenance costs of the equipment; the conveying equipment causes abnormal loads in each link due to the deviation of the center of gravity of the load from the equipment axis, resulting in increased losses;

[0004] During operation, the belt may easily deviate due to an incorrect coal drop point. The usual way to solve this problem is for maintenance personnel to enter the coal drop pipe and weld a wear-resistant guide plate to adjust the angle.

[0005] This treatment method has the following two disadvantages and safety hazards: first, the coal drop point cannot be adjusted at any time according to changes in coal type and water content; second, welding in the coal drop pipe is a limited space operation. During the operation, maintenance personnel face safety hazards such as coal powder ignition and harmful gas injuries caused by welding. Therefore, the method of welding and fixing the guide plate at the discharge port is frequent and unsafe. Therefore, we proposed a belt feed adjustment mechanism. Utility Model Content
