Mine protective net throwing device
The invention relates to a mine protective net throwing device which comprises a support plate. A front baffle is arranged on the front end face of the support plate. An oil cylinder is fixedly arranged on the rear end face of the front baffle. A traction plate is installed on a shaft of the oil cylinder. The left and right ends of the traction plate are each provided with two through holes. The left and right sides of the upper end face of the support plate are each provided with a spring end sleeve. A compression spring is arranged inside a cavity of each spring end sleeve. A throwing spear is communicated with the interior of each compression spring. A pair of supporting longitudinal columns are arranged at the upper portion of each spring end sleeve. Each supporting longitudinal column is sleeved with a pressing rotating block. The rear ends of the supporting longitudinal columns are correspondingly inserted into the through holes in the traction plate. The throwing spears are compressed on the compression springs through the traction plate, and the compression springs are flexibly controlled by the pressing rotating blocks to limit the throwing spears, the throwing spears can be flexibly compressed and released; and in other words, the throwing spears can be flexibly compressed or released, and the throwing spears are utilized for controlling throwing of a protective net, so that the labor intensity of workers is lowered, and the throwing efficiency and the throwing effect of the protective net are improved.
