DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Referring to Figures (1-4), a feeding device for freshwater fish farming includes a feeding box 2 and a buoy 7. The top of the feeding box 2 is provided with a flip cover 1 by a hinge. The feeding box 2 is sequentially provided with a lower hopper 3 and a distribution bin 4. A throwing plate 5 is provided at the center position of the top of the buoy 7. The feeding box 2 is installed above the throwing plate 5. A center of gravity counterweight block 8 is provided at the bottom of the buoy 7, and a traction hanging ring 6 is provided on the outside of the buoy 7.

[0020] The throwing disc 5 includes a chassis body 9, a damping rod 10, a power chassis 11 and a throwing turntable 12. A damping rod 10 is installed on the top of the chassis body 9. One end of the damping rod 10 is connected to the top of the chassis body 9 and the other end is connected to the bottom of the material spreading box 2. The power chassis 11 is embedded in the top of the chassis body 9. The throwing turntable 12 is rotatably arranged above the power chassis 11. Four groups of trapezoidal vertical blades are arranged on the top of the throwing turntable 12, and a rotating shaft 13 is connected at the center of the bottom. One end of the rotating shaft 13 is connected to the throwing turntable 12 and the other end penetrates into the power chassis 11 and is connected to the output end of the motor arranged in the power chassis 11. An arc-shaped paddle 14 is arranged at the bottom of the throwing turntable 12. A brush 15 is arranged on the arc-shaped paddle 14, and the brush 15 is in contact with the top surface of the power chassis 11.

[0021] The material distribution bin 4 includes a trapezoidal material distribution hopper 16 and a material distribution roller 17, and the material distribution roller 17 is rotatably arranged at the position of the material discharge port of the trapezoidal material distribution hopper 16, and a circle of grooves is arranged on the material distribution roller 17. A transparent film is sleeved on the outer diameter of the damping rod 10. The material distribution bin 4 is provided with a motor for driving the material distribution roller 17 to rotate, and the motor is provided with a continuously variable transmission.

[0022] When the device is in use, the bait is put into the lower hopper 3, and the buoy is pulled to the throwing position by a floating boat. During throwing, the dividing roller 17 and the throwing turntable 12 are driven to rotate by a motor, and the bait in the lower hopper 3 falls from the trapezoidal dividing hopper 16 in the dividing bin 4 into the groove of the dividing roller 17. The rotation of the dividing roller 17 drives the bait in the groove to rotate, and finally falls from the lower feeding port of the trapezoidal dividing hopper 16 and falls onto the throwing turntable 12. The vertical blades on the throwing turntable 12 rotate to sprinkle the falling bait, and the rebounded material falls into the bottom of the throwing turntable 12, which may cause the turntable to get stuck. The arc-shaped paddle 14 and the brush 15 rotate to throw the rebounded bait material out, thereby ensuring the stable throwing operation of the throwing turntable.

[0023] The orientations or positional relationships shown in the drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.
