Automatic balancing method of parallel type mining crusher discharge port material receiving tray

Abstract

The invention discloses an automatic balancing method of a parallel type mining crusher discharge port material receiving tray, and belongs to the field of coal mine machinery equipment. The balancing method comprises the following steps of: detecting the rotation direction of a baseplate (3-1) by using a tilt angle sensor (4); controlling the expansion and contraction of a hydraulic cylinder (2-2) in a hydraulic control device (2) by using a single chip microcomputer (5) according to the rotation direction of the baseplate (3-1); and accurately controlling the expansion and contraction of the hydraulic cylinder (2-2) by using the single chip microcomputer (5) according to comparison between the expansion and contraction quantity of the hydraulic cylinder (2-2), which is detected by a magnetostrictive displacement sensor (6) arranged on an expansion link of the hydraulic cylinder (2-2), and the theoretic expansion and contraction quantity so as to enable materials falling on a conveyor belt through a material receiving tray (1) to be balanced. The automatic balancing method has good adaptability and high detection and control accuracy and is not affected by working environments.

Description

technical field [0001] The invention relates to an automatic balancing method for a parallel-connected material receiving tray, in particular to an automatic balancing method for a parallel-connected mining crusher outlet outlet feeding tray, and belongs to the field of coal mine machinery and equipment. 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 fall...

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
