DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4, the present utility model provides a technical solution: a structure of an automatic chemical supply device, including a bracket 1. A motor 2 is fixedly installed on one side of the bracket 1. The output end of the motor 2 is fixedly connected to a reciprocating lead screw 3. One end of the reciprocating lead screw 3 is rotatably connected to the bracket 1. A rack 4 is fixedly connected to one side of the bracket 1. A transmission block 5 is provided on the bracket 1. The reciprocating lead screw 3 is threadedly connected to the top end of the transmission block 5. A round shaft 6 is rotatably connected to the middle position on one side of the transmission block 5. One end of the round shaft 6 is fixedly connected to a gear 7. The end of the round shaft 6 away from the gear 7 is fixedly connected to a transmission disc 8. An extrusion shaft 9 is fixedly connected to a position away from the center on one side of the transmission disc 8. Limiting blocks 10 are fixedly connected to both sides of the transmission block 5 close to the transmission disc 8. Limiting rods 11 are slidably connected to both limiting blocks 10. A transmission plate 12 is fixedly connected between the two limiting rods 11. A support plate 13 is fixedly connected to the top end of the transmission plate 12. A placement bin 14 is fixedly connected to the top end of the support plate 13. A discharge port 15 is opened at the middle position of the bottom end of the placement bin 14.

[0018] Mounting plates 16 are fixedly connected to both sides of the bracket 1. Bolt holes are opened on the mounting plates 16, which is convenient for installing the bracket 1 through the mounting plates 16. The discharge port 15 is designed with a rectangular structure, and the size of the discharge port 15 is set corresponding to the material, which is convenient for the material in the placement bin 14 to fall stably from the discharge port 15 when the placement bin 14 shakes. The gear 7 is arranged corresponding to the rack 4, and the gear 7 is meshed with the rack 4, which is convenient for the rack 4 to squeeze the gear 7, so that the squeezed gear 7 rotates. An extrusion groove is opened on the transmission plate 12, and the extrusion groove is arranged corresponding to the extrusion shaft 9, which is convenient for the extrusion shaft 9 to squeeze the transmission plate 12, so that the transmission plate 12 makes a reciprocating motion.

[0019] Specifically, when using the present utility model, the bracket 1 is installed at the top of the sewage flow section where dosing is required. Chemical agents are added to the placement bin 14. The motor 2 is started. The motor 2 drives the reciprocating lead screw 3 to rotate. The reciprocating lead screw 3 drives the transmission block 5 to make a reciprocating motion. The moving transmission block 5 drives the round shaft 6 to move. The round shaft 6 drives the gear 7 to rotate. Since the gear 7 is meshed with the rack 4, the rack 4 squeezes and drives the gear 7. The squeezed gear 7 drives the round shaft 6 to rotate. The round shaft 6 drives the transmission disc 8 to rotate. The transmission disc 8 drives the extrusion shaft 9 to rotate. The extrusion shaft 9 squeezes the transmission plate 12. The squeezed transmission plate 12 makes a reciprocating motion under the limiting action of the limiting blocks 10 and the limiting rods 11. The moving transmission plate 12 drives the support plate 13 to move. The support plate 13 drives the placement bin 14 to move. The reciprocating placement bin 14 drives the chemical agents inside the bin to shake. The shaken agents fall into the sewage along the discharge port 15. And due to the consistent shaking frequency, the falling agents are scattered in a Z-shaped curve trajectory, and the scattering is relatively uniform.

[0020] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
