[0023] In this embodiment, two cross bars are fixedly installed on the top left side of the inner wall of the treatment pool 1, and the right side of the cross bar is fixedly connected to the right side of the inner wall of the treatment pool 1. The outer peripheral wall of the cross bar is slidably sleeved with a sleeve with one end fixedly connected to the bottom of the cross plate 2.

[0024] Specifically, the cross plate 2 can slide on the treatment tank 1 through the arrangement of the cross bar and the sleeve.

[0025] In this embodiment, the unloading mechanism 4 includes a mounting plate 41, a slide groove 42, a movable plate 43, a telescopic spring 44 and a unloading hole 45. The mounting plates 41 are fixedly installed at the front and rear ends of the bottom of the medicine storage box 3. The two mounting plates 41 are provided with slide grooves 42 on the opposite sides. Slide blocks are slidably installed inside the slide grooves 42. The movable plate 43 is fixedly installed on the opposite sides of the two slide blocks. The right side of the slider is fixedly installed with a telescopic spring 44 with one end fixedly connected to the right side of the inner wall of the slide groove 42. The top of the movable plate 43 is provided with a unloading hole 45, and a protrusion is provided on the left side of the unloading hole 45.

[0026] Specifically, when the movable plate 43 is squeezed, it will move rightward to compress the telescopic spring 44. When the discharge hole 45 moves to below the medicine storage box 3, the medicine in the medicine storage box 3 will fall into the treatment tank 1 along the discharge hole 45.

[0027] In this embodiment, the driving mechanism 6 includes a mounting frame 61, a driving motor 62, a belt pulley 63, a stirring rod 64, a belt 65 and a cam 66.

The two ends of the contact of the relay are connected in series with the drive motor 51 and the drive motor 62. The controller 12 controls the power on of the relay coil to close the contacts, and the drive motor 51 and the drive motor 62 are turned on and can run.

[0030] The working principle of the above embodiment is:

[0031] (1) Add the medicine to be added into the medicine storage box 3, the controller 12 turns on the driving motor 62 to rotate the left belt pulley 63, and the left belt pulley 63 rotates with the stirring rod 64 through the belt 65. When the cam 66 rotates with the stirring rod 64, it can reciprocate and squeeze the movable plate 43. When the movable plate 43 is squeezed, it will move to the right to compress the telescopic spring 44. When the discharge hole 45 moves to the bottom of the medicine storage box 3, the medicine in the medicine storage box 3 will fall into the treatment tank 1 along the discharge hole 45, and the stirring rod 64 will stir the water in the treatment tank 1, so that the sewage in the treatment tank 1 and the medicine are repeatedly mixed;

[0032] (2) The controller 12 starts the driving motor 51 to rotate the driving gear 52, and the driving gear 52 rolls on the rack 53, thereby driving the horizontal plate 2 to move horizontally, changing the drop position of the medicine, and performing a comprehensive medicine delivery operation.
