Automatic balancing device for discharging outlet material receiving plates of parallel-connection mining crusher

Abstract

The invention discloses an automatic balancing device for discharging outlet material receiving plates of a parallel-connection mining crusher, and belongs to the field of coal mine mechanical equipment. The automatic balancing device comprises the material receiving plates (1), a rotary bottom plate device (3), a single-chip microcomputer (5) and a supporting seat (8). A hydraulic control device (2) is connected between each material receiving plate and the rotary bottom plate device (3); the rotary bottom plate device (3) is hinged to the supporting seat (8); an inclination angle sensor (4) is arranged on a bottom plate (3-1); each hydraulic cylinder (2-2) is provided with a magnetostrictive displacement sensor (6); the output ends of the inclination angle sensor (4) and the magnetostrictive displacement sensors (6) are connected with the input end of the single-chip microcomputer (5), and the output end of the single-chip microcomputer (5) is connected with control circuits of the hydraulic control devices (2). The automatic balancing device can automatically adjust the balance of the two material receiving plates to reasonably distribute the positions of materials which fall onto a conveying belt, so that the abrasion damage to the conveying belt is relieved. The automatic balancing device for the discharging outlet material receiving plates of the parallel-connection mining crusher is good in adaptability, good in anti-disturbance performance and long in service life.

Description

technical field [0001] The invention relates to an automatic balancing device for a parallel-connected feeding tray, in particular to an automatic balancing device for a feeding tray at a discharge port of a parallel mining crusher, belonging to the field of coal mine machinery. Background technique [0002] Crusher is an essential equipment in coal mine production operations. When the crushing capacity is large, a single crusher cannot meet the crushing requirements. Therefore, two crushers are often used in parallel to achieve the purpose of expanding production capacity and improving crushing efficiency. When two crushers are connected in parallel for crushing, the two crushers are arranged at the end of the conveyor belt, and the straight line where the outlets of the two crushers are located is perpendicular to the moving direction of the conveyor belt. Although this can improve the crushing efficiency, the Since the speed of the materials falling from the outlets of th...

AI Technical Summary

Problems solved by technology

When two crushers are connected in parallel for crushing, the two crushers are arranged at the end of the conveyor belt, and the straight line where the outlets of the two crushers are located is perpendicular to the moving direction of the conveyor belt. Although this can improve the crushing efficiency, the Since the speed of the materials falling from the outlets of the two crushers cannot be the same all the time, and the outlets of the crushers are fixed, it cannot be real-time based on the speed of the materials falling and the materials falling per unit time. Therefore, the material falling on the conveyor belt is unbalanced, resulting in unbalanced force on both sides of the conveyor belt, which accelerates the damage of the conveyor belt, increases the time for repairing the damaged parts and maintaining the equipment, and then Affects the production efficiency of the entire production line
