[0017] Drug replacement: The staff walks on the walking pedal and moves to the designated position of the dosing mechanism. The foot-operated drive assembly limits and fixes the stepped drive assembly through the limit assembly. The descending drive assembly drives the linkage assembly to operate, and the linkage assembly drives the basket to rotate 90 degrees and rise, so that the basket rotates and rises above the water surface of the breeding pond and is located on the side of the walking pedal.

[0019] Through the design of the driving assembly of the present invention, when it is necessary to replace or refill the medicine in the basket, the staff walks on the walking pedal to move to the dosing mechanism at the specified position, and then steps on the top of the vertical rod on the driving assembly to make the vertical rod descend vertically. The descending vertical rod will push the bottom U-shaped frame to descend, and the U-shaped frame will squeeze the inner wall of the slide groove through the abutment block to push the fixed plate to rotate. The fixed plate drives the half gear to rotate on the fixed shaft.

Under the guidance of the arc-shaped guide groove, the rotating cylinder will rotate, thereby achieving the simultaneous rising and rotating movements of the rotating cylinder, thereby driving the side plates and the basket to rise and rotate synchronously, so that the basket rotates and rises above the water surface of the breeding pond and is located on the side of the walking pedal. At this time, the cover plate can be unscrewed to put new medicine into the basket.

[0022] Through the design of the lubrication component of the present invention, when the slider slides in the annular slide groove and the protrusion slides in the arc guide groove, the spherical column will be squeezed and triggered, and the spherical column will move into the oil guide cavity and push the fixed block to penetrate into the plug-in groove and squeeze the elastic pad. The elastic pad will be deformed, and the fixed block will insert the catheter into the interior of the annular ring while moving and squeeze open a number of blocking blocks. At this time, the catheter is connected with the end opening of the oil pipe, and the lubricating oil in the oil pipe will flow into the oil guide cavity, and the lubricating oil in the oil guide cavity will flow out through the gap between the spherical surface of the spherical column and the opening of the oil guide cavity, so as to achieve the purpose of lubrication and reducing wear.

[0052] Embodiment six;

[0053] like Figure 1-5 As shown, according to an embodiment of the present invention, a method for using a device for administering medicine for preventing diseases in farmed fish is also provided, and the device for administering medicine for preventing diseases in farmed fish comprises the following steps:

[0054] Step S101, normal use: the medicine is placed inside the basket 13 on the dosing mechanism, the basket 13 is placed under the water surface of the breeding pond 37, and the medicine is slowly released from the gap of the basket 13 into the breeding pond 37, thereby preventing and controlling the fish school;

The medicine is slowly released from the gap in the basket 13 into the culture pond 37, thereby preventing and treating the fish. When it is necessary to replace or refill the medicine inside the basket 13, the staff walks on the walking pedal 1 and moves to the dosing mechanism at the designated position, and then steps on the top of the vertical rod 22 on the pedal drive assembly to make the vertical rod 22 descend vertically. When the vertical rod 22 descends, it will bring the rotating ring 25 and the limit plate 26 through the circular opening 28 and the inlet and outlet respectively. 29 penetrates into the movable groove 27, and then, the rotating ring 25 and the limiting plate 26 are rotated through the distance between the vertical rod 22 and the circular opening 28, so that the limiting plate 26 rotates to the bottom of the limiting slot 30.

At this time, the cover plate 14 can be unscrewed to put new medicine into the basket 13. After the medicine is put in, the vertical rod 22 is stepped on again to disengage the limit plate 26 from the limit slot 30, and the rotating ring 25 and the limit plate 26 are rotated in the opposite direction to make the limit plate 26 dock with the inlet and outlet 29 again. Subsequently, the vertical rod 22 is released, and under the action of the spring 24 and the weight of the basket 13, the drive assembly and the linkage assembly are reset and moved.
