DETAILED DESCRIPTION

[0015] As Figures 1-3 shown: a multi-station distribution valve, including hopper 2, the outer wall of hopper 2 front and rear side are fixedly connected support 1, the bottom of hopper 2 is fixedly connected distribution box 3, the top of distribution box 3 middle part is communicated with the bottom of hopper 2, the bottom of distribution box 3 left and right sides are fixedly communicated blanking pipeline one 4 and blanking pipeline two 5 respectively, the outer wall right side bottom of hopper 2 is fixedly installed vibrator 6, the front and rear inner side walls of distribution box 3 are all provided with sliding groove 7, sliding groove 7 extends left and right, the inner side of distribution box 3 has distribution sliding block 8, the top and bottom of distribution sliding block 8 are slidably connected with the inner wall of distribution box 3, the front and rear walls of distribution sliding block 8 are all fixedly connected convex strip 9, convex strip 9 is in the inside of sliding groove 7, convex strip 9 is slidably connected with sliding groove 7, the top left and right sides of distribution sliding block 8 are all provided with blanking hole 10, blanking hole 10 is adapted to the bottom of hopper 2, the top of blanking pipeline one 4 and the top of blanking pipeline two 5, the right side wall of distribution box 3 is fixedly installed air cylinder 11, the piston rod of air cylinder 11 penetrates the right side wall of distribution box 3, the piston rod of air cylinder 11 is slidably connected with distribution box 3, the left end of piston rod of air cylinder 11 is fixedly connected with the right end of distribution sliding block 8, when left blanking hole 10 is communicated with the bottom of hopper 2, right blanking hole 10 is communicated with blanking pipeline two 5, when left blanking hole 10 is communicated with blanking pipeline one 4, right blanking hole 10 is communicated with the bottom of hopper 2.
