Problems solved by technology

[0002] At present, in the sealing process of underground gas treatment, due to the use of pneumatic pumps or electric pumps, they are cumbersome, complicated to operate, and difficult to maintain. Problems often occur during construction and affect production.
In high-gas mines, no matter whether you use a pneumatic pump or an electric pump, you need a power source. The operation method of using a power source in the mine has potential safety hazards that may cause gas explosions.

Abstract

The invention discloses a manual grouting pump and relates to the technical field of boring and hole sealing under a coal mine. The manual grouting pump comprises a grout bucket, wherein a filter screen for dividing the grout bucket into a containing cavity and an extracting cavity is arranged in the grout bucket, an overflow hole is formed in the upper end of the containing cavity, and a blowing hole is formed in the lower end of the containing cavity; a grout absorption pipe is inserted into the extracting cavity and extends into the grout, and the other end of the grout absorption pipe is connected to a manual piston pump; a grout discharge pipe is arranged on the sidewall of the manual piston pump. The invention provides the manual grouting pump, which is capable of realizing safety hole sealing under the coal mine.

Description

technical field [0001] The invention relates to the technical field of underground drilling and sealing, in particular to a manual grouting pump. Background technique [0002] At present, in the sealing process of underground gas treatment, due to the use of pneumatic pumps or electric pumps, they are cumbersome, complicated to operate, and difficult to maintain. Problems often occur during construction and affect production. In high-gas mines, no matter whether you use a pneumatic pump or an electric pump, you need a power source. The operation method of using a power source underground has potential safety hazards that may cause gas explosions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manual grouting pump capable of safely sealing holes in mines. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a manual grouting pump, including a grout bucket, ...
