犁煤器配煤自动控制

Coal Distribution Automatic Control of Coal Plougher

用继电器组成的计数器 ,是一个很好的步进器 ,它能够根据输入脉冲的个数 ,逐次向前翻转计数。由步进器和输入矩阵、输出矩阵便组成了犁煤器配煤的自动控制装置。此外 ,还必须配置中煤位切换电路 ,具有跳步功能和召唤配煤功能 。

The counter consisting of the relays is a very good step-by-step device, capable to count one by one in forward turns according to the number of input pulses. The automatic control for coal distribution of the coal plougher is made of the step-by-step device, input matrix and output matrix. In addition a switching circuit for middle coal level must be installed with functions of jump and calling for coal distribution. Thus a complete automatic coal distribution for the coal plougher is completed.
