DETAILED DESCRIPTION

[0015] The present invention is further explained below in conjunction with the accompanying drawings and embodiments, which should not be used to limit the protection scope of the present invention. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0016] Combined with Figure 1-2 The multi-point quantitative feeder of solid powder medicine shown in the figure comprises a frame 1, a medicine hopper 2, a screw feeder 3, a mixing chute 4 and a water supply pipeline 5.

[0017] The medicine hopper 2 is arranged on the upper rear side of the frame 1; the spiral feeder 3 is arranged on the frame 1 below the medicine hopper 2, the groove on the upper side of the spiral feeder 3 shell is connected to the outlet below the medicine hopper 2, and a plurality of medicine outlets 31 are evenly spaced along the length direction of the shell on the lower side of the spiral feeder 3.

[0018] The mixing chute 4 is tiltedly arranged on the frame 1 at the lower side of the screw feeder 3, and a plurality of chutes are arranged in the mixing chute 4. A splash plate 44 is horizontally arranged on the upper end of the mixing chute 4 across each chute, and a medicine receiving funnel 45 is arranged on the splash plate 44 in correspondence with each medicine outlet 31 of the screw feeder 3. The outlets of the medicine receiving funnel 45 are arranged in correspondence with each chute, and mixing baffles are evenly spaced on the inner side walls of each chute. The mixing baffles include a guide inclined plate 41 and an L-shaped buffer plate 42. The guide inclined plates 41 and the L-shaped buffer plates 42 are arranged in pairs on both sides of the chute in a staggered manner. On the wall, a guide inclined plate 41 is arranged on one side wall of the chute, an outlet is formed between the end of the guide inclined plate 41 and the other side wall, an L-shaped buffer plate 42 is arranged on the other side wall below the outlet, and the L-shaped buffer plate 42 and the other side wall form a U-shaped buffer zone, and the water outlet and outlet pipes corresponding to the water inlet pipe at the upper and lower ends of the chute are arranged with guide inclined plates 41, and the bottom of the lower end of each chute is arranged with an outlet pipe 43; a plurality of water supply pipelines 5 are connected to the upper end of each chute of the mixing chute 4, and each water supply pipeline 5 on the outside of the mixing chute 4 is provided with a flow regulating valve 51 and a switch valve 52.
