Abstract

The invention relates to a pulp spraying machine for a coal mine tunnel. A swing arm is fixedly connected with a rotary table of a rotating platform, and a base of the rotating platform is fixedly connected with a lifting cross beam; a horizontal bracket is arranged below the lifting cross beam; two lifting units are symmetrically arranged on the left and right sides of the horizontal bracket, first support seats are arranged on the ends of the cross beam in an inclined mode, second support seats are arranged on the lower part of the cross beam in the inclined mode, cylinder seats of hydraulic cylinders A are hinged to the lower ends of the second support seats, the inflection points of V-shaped rotating arms are hinged to the lower ends of the first support seats, the heads of piston rods of the hydraulic cylinders A are hinged to the lower ends of the V-shaped rotating arms, and the upper ends of the V-shaped rotating arms are hinged to the base which is arranged on the lower part of the lifting cross beam; a chute is formed in the middle of the lower surface of the lifting cross beam, and a guide rail is arranged on the upper end of the base; first limiting stops are symmetrically arranged on both ends of the lifting cross beam, and the chute is positioned between the two first limiting stops; the lower part of the horizontal bracket is fixedly connected with a vertical lifting hydraulic cylinder; a pulp spraying head A is arranged on one end of the swing arm. The pulp spraying machine has the advantages of small size and flexibility in operation, and the pulp spraying effect can be effectively guaranteed.

Description

technical field [0001] The invention relates to a spraying equipment for a coal mine roadway, in particular to a spraying machine for a coal mine roadway. Background technique [0002] Due to the long swing arm and large volume of the existing spraying machine, the operation is not flexible enough, and the spraying effect is not easy to control. This situation is especially obvious when the working space is small. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a spraying machine for coal mine roadway, which is small in size, flexible in operation, can realize vertical lifting, and can effectively guarantee the spraying effect. [0004] The invention provides a spraying machine for coal mine roadway, which includes a swing arm, a spraying head A, and a rotating platform. The lifting beam is fixedly connected; a horizontal support is provided under the lifting beam; a lifting unit is symmet...
