Embodiment Construction

[0009] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0010] The manual hole sealing pump for mining of the present invention mainly consists of an agitator 1 for sealing slurry material, a bevel gear set 2, a chain gear set 3, a hand wheel 4, a pressure rod 5, a check valve 7, a plunger pump 8 and a pump. Slurry valve 13 constitutes. It is divided into two parts: stirring device and mud conveying device. The stirring device includes agitator 1, bevel gear set 2 connected with agitator 1, bevel gear set 2 is connected with transmission shaft 3, bevel gear set 2 includes driving wheel and driven wheel , driving wheel is that bull wheel is located at transmission shaft 3 bearing seats outside one end, and driven wheel is that small wheel is located on the rotating shaft of agitator 1. The other end of the outer side of the transmission shaft 3 support seat is provided with a shaking handle 4 that drives the bev...

Besides, said invention also provides its working principle and concrete application method.

Description

technical field [0001] The invention relates to a mine-used manual hole sealing pump, which is especially suitable for pressure injection of sealing material in coal mine gas drainage drilling and pressure measuring drilling, or sealing of coal seam drilling in the case of no electricity and no pressurized wind. Background technique [0002] Gas drainage is the fundamental measure to prevent and control gas disasters in coal mines, and the quality of the sealing of drainage holes is directly related to the effect of gas drainage. In addition, the quality of hole sealing is also a decisive factor for the accuracy of coal seam gas pressure measurement. The sealing of coal mine gas drilling is to use manual or mechanical equipment to inject the sealing material into the drilling, so that the sealing material is in close contact with the periphery of the drilling, so as to prevent the external air from entering the hole during gas drainage and causing the...
