Uniform slurry throwing device for indoor wall surface

The invention relates to a uniform slurry throwing device for an indoor wall surface. The problems that slurry throwing is not uniform through a bat, slurry needs to be repeatedly dipped, and the labor intensity is large are effectively solved. According to the technical scheme, the uniform slurry throwing device comprises an outer shell, wherein a barrel is arranged in the outer shell, a front disc and a rear disc are arranged outside the barrel, sliding grooves are formed in the discs, sliding blocks are arranged in the sliding grooves, and first permanent magnets are arranged outside the sliding blocks; second permanent magnets are arranged on the inner wall of the outer shell, rotating shafts are installed on the sliding blocks, and slurry bats are installed on the rotating shafts; gears are installed at the front ends of the rotating shafts, push rods are fixed to the discs, racks meshed with the gears are fixed to the outer ends of the push rods, the push rods can reciprocate inthe radial direction of t
