The invention relates to a rotation air supply mechanism of a drilling machine and belongs to the technical field of drilling machine equipment. The mechanism comprises a three-stage cylindrical gear reducer, wherein one end of a hollow output shaft of the reducer is connected to an air supply pipe of a center air supply mechanism by a seal connection device; the seal connection device comprises a connection pipe and a connection end cap; the connection end cap and the connection pipe sleeve one end of the output shaft; the connection end cap is installed on a shell body of the reducer; a rubber seal pad is disposed in the connection end cap; the rubber seal pad sleeves the output shaft; one end of the connection pipe is installed on the connection end cap and the other end of the connection pipe is connected to the air supply pipe; and a seal ring is disposed at a joint between the connection pipe and the air supply pipe. The mechanism has the advantages that sealing effects are enhanced, and leakage and venting are avoided.
Description
technical field [0001] The invention relates to a rotary air supply mechanism for a drilling rig, belonging to the technical field of drilling rig equipment. Background technique [0002] Drilling rigs can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. The drilling rig drives the drilling tool to drill underground to obtain physical geological data. The drilling tool is composed of a drill pipe, a spherical tooth drill bit and an impactor. When drilling, two drill pipe extensions are used to drill. The rotary air supply mechanism is composed of a rotary motor, a rotary reducer, and an air supply gyrator. The sealing effect of the existing rotary air supply mechanism is not good, and there are phenomena such as outgassing, water escaping, dripping, and liquid leakage, which not only increases the damage rate of the equipment, but also reduces the construction quality...
