一种给煤机自动给煤控制系统
摘要：
本发明公开一种给煤机自动给煤控制系统，包括液位继电器(5)、继电器控制系统以及布置在煤仓(1)上方的若干个铜条(2)，铜条用于检测煤仓内的含煤量，并通过电缆与液位继电器连接；铜条与液位继电器配合使用，根据煤仓内的含煤量控制给煤机的工作与否。本发明利用液位继电器的工作原理，设计了给煤机自动控制系统，根据煤仓内含煤量的检测情况，控制给煤机的工作与否，保证了煤仓的正常供煤，避免出现煤仓无煤或满仓的情况，保证了矿井提升安全，减少了事故率，提高了经济效益和安全性。
摘要（英）：

The invention discloses an automatic coal feed control system for a coal feeder. The automatic coal feed control system comprises a liquid level relay (5), a relay control system and multiple copper strips (2) distributed above a coal bin (1). The copper strips are used for detecting the amount of coal in the coal bin and connected with the liquid level relay through cables. The copper strips and the liquid level relay are used in cooperation. The coal feeder is controlled to work or not according to the amount of the coal in the coal bin. According to the automatic coal feed control system for the coal feeder, by the adoption of the working principle of the liquid level relay, the automatic control system is designed for the coal feeder; and the coal feeder is controlled to work or not according to the detection condition of the amount of the coal in the coal bin, normal coal supply of the coal bin is guaranteed, it is avoided that the coal bin is free of the coal or filled with the coal, mine hoisting safety is guaranteed, the accident rate is reduced, economic benefits are increased, and safety is improved.
