Embodiment

[0020] Refer to Figures 1 to 4, in an embodiment of the present utility model, an automatic dissolving, spraying and dosing device for a coal dust suppressant includes a bottom plate 1 and a fixing plate 7. An outer wall of the fixing plate 7 is fixedly connected with a medicine box 8. An upper end of the medicine box 8 is provided with a medicine adding port 9. One end of the medicine adding port 9 is fixedly connected with a booster pump 11. The booster pump 11 is fixedly connected to the outer wall of the fixing plate 7. A lower output end of the booster pump 11 is fixedly connected with a hose 12. One end of the hose 12 is fixedly connected with a nozzle 14. A lower end of the nozzle 14 is fixedly connected with a motor 135. A four-bar mechanism 13 is arranged below the motor 135. An inner wall of the bottom plate 1 is rotatably connected with a lead screw 4. An outer wall of the lead screw 4 is provided with a first gear 2. An inner wall of the bottom plate 1 is rotatably connected with a second gear 3. An inner wall of the second gear 3 is fixedly connected with the lead screw 4. The lead screw 4 is threadedly connected to an inner wall of the fixing plate 7. A guide rod 5 is slidably connected to an inner wall of the fixing plate 7. The guide rod 5 is fixedly connected to an upper surface of the bottom plate 1. The first gear 2 meshes with the bottom plate 1. The medicine adding port 9 is threadedly connected to an outer wall of the medicine box 8. A sealing ring is arranged inside the medicine adding port 9. A connecting pipe 10 is arranged between the medicine box 8 and the booster pump 11. The four-bar mechanism 13 includes a first connecting rod 131, a second connecting rod 132, a third connecting rod 133, and a fourth connecting rod 134. The second connecting rod 132 is fixedly connected to an outer wall of the booster pump 11. The fourth connecting rod 134 makes a circular motion relative to the motor 135. The third connecting rod 133 swings relative to the second connecting rod 132. The first connecting rod 131 swings relative to the second connecting rod 132. The third connecting rod 133 is hinged to the second connecting rod 132. The first connecting rod 131 is hinged to the second connecting rod 132. The fourth connecting rod 134 is hinged to the first connecting rod 131. The fourth connecting rod 134 is hinged to the third connecting rod 133. An upper surface of the first connecting rod 131 is fixedly connected with the motor 135. A lower output end of the motor 135 penetrates through the first connecting rod 131. A lower output end of the motor 135 is fixedly connected with the fourth connecting rod 134. An upper surface of the first connecting rod 131 is higher than an upper surface of the third connecting rod 133. By providing the guide rod 5, the stability of the fixing plate 7 during lifting and lowering can be maintained. By providing the four-bar mechanism 13, it is convenient to drive the nozzle 14 to swing repeatedly. The swing of the nozzle 14 is realized by a continuously rotating motor 135, making the overall structure simple.

[0021] Working principle: When in use, first, the liquid in the medicine tank 8 is pumped into the connecting pipe 10 by the booster pump 11. Subsequently, due to the increase in pressure, the liquid is sent into the nozzle 14 through the hose 12. Since the opening of the nozzle 14 is small, the liquid with high pressure is released and sprayed out as atomized liquid. At this time, the motor 135 drives the fourth connecting rod 134 to do circular motion. Then, under the action of the first connecting rod 131 and the third connecting rod 133, the first connecting rod 131 swings, and then the nozzle 14 swings, increasing the spraying range. The atomized liquid is widely covered through repeated swinging. When adding medicine, the adjusting handle 6 is driven to rotate the second gear 3, which in turn drives the first gear 2 to rotate, and then drives the lead screw 4 to rotate. The rotation of the lead screw 4 can lower the upper fixing plate 7, and then the manual medicine adding effect is achieved by opening the medicine adding port 9.

[0022] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
