Liquid adaptive device for bees

The invention relates to a liquid adaptive device for bees. The technical scheme includes that the liquid adaptive device comprises a feeding trough (1), a buoyancy ball (2), a ball valve connecting rod (3), a guide sleeve (4), a guide sleeve (4), a ball valve (5), a liquid storage tank (10) and a feeding bottle (13). The feeding trough (1) is mounted at the lower end of the feeding bottle (13), the ball valve (5) is fixed at the edge of a cover plate (11) through a nut (8), the buoyancy ball (2) is arranged under the ball valve (5), one end of the ball valve connecting rod (3) penetrates the guide sleeve (4) and is fixedly connected with a valve spool (15) of the ball valve (5), the other end of the ball valve connecting rod (3) is fixedly connected with the buoyancy ball (2), a ball center of the valve spool (15) and a ball center of the buoyancy ball (2) are positioned on an extended line of the axis of the ball valve connecting rod (3), and an inlet of the ball valve (5) is communicated with an outlet of the liquid storage tank (10) through a hose (9). The liquid adaptive device has the advantages that the liquid adaptive device is simple in structure and fine in sealing performance, and liquid in the feeding trough (1) can be automatically supplied according to bee feeding rate.
