DESCRIPTION OF THE INVENTION

[026] As shown in Figs. 1 and 2, the live bait feeding device according to the embodiment of the present invention comprises a floating body frame mechanism and a plurality of box units 1 arranged on the floating body frame mechanism. The floating body frame mechanism is used for floating on the water surface, and comprises a plate shaped floating body 3, a control box 6 arranged on the floating body 3 and a battery tank 5. The floating body 3 is provided with a plurality of loading ports 31. The box unit 1 is inserted into the loading port 31.

[027] As shown in Fig. 4, the box unit 1 is used for containing live bait feed, and the bottom of the box unit 1 is provided with a feeding port 11. In use, the bottom of the box unit 1 is below the water surface, and soaking in water can keep the live bait feed in the box unit 1 alive. An electromagnet stopper 2 is arranged at the bottom of each box unit 1, and the electromagnet stopper 2 is matched with the feeding port 11 at the bottom of the box unit 1.

[028] As shown in Figs. 3 and 4, the side walls and bottom of each box unit 1 are provided with a plurality of water-permeable holes, so that the water in the outer box unit 1 can be exchanged with the outside, and the size of the water-permeable holes needs to meet the requirement that live bait cannot pass through. The side wall of the box unit 1 is provided with a clamping port 12, and the floating body 3 is provided with a clamping mechanism 4 which is adapted to the clamping port 12 at the periphery of the bearing opening 31, and the box unit 1 is fixed on the floating body 3 through the clamping mechanism 4.

[029] The electromagnet stopper 2 includes a stopper 21 for shielding the feeding port 11 and a suction cup electromagnet 22 connected with the stopper 21. The lower surface of the box unit 1 is provided with an iron block 13 matched with the suction cup electromagnet 22. The suction cup electromagnet 22 is electrically connected with the control box 6 through wires, and under the control of the control box 6, the suction state of the iron block 13 is realized to close or open the feeding port 11.

[030] The feeding port 11 is round, and the stopper 21 is a matching round plate. At least two iron blocks 13 are arranged on the bottom surface of the box unit 1, and each iron block 13 is distributed around the feeding port 11. Each electromagnet stopper 2 also includes a mounting frame, and the stopper 21 and each suction cup electromagnet 22 are fixedly mounted on the mounting frame. The shape of the installation frame is such that when each suction cup electromagnet 22 is adsorbed on the corresponding iron block 13, the stopper 21 blocks the feeding port 11.

[031] In this embodiment, each electromagnet stopper 2 includes two suction cup electromagnets 22, and the shape of the installation frame is similar to that of a trident, wherein the middle rod is fixedly connected with the lower surface of the stopper 21, and the suction cup electromagnets 22 are installed at the ends of the two side rods. The number of iron blocks 13 at the bottom of the box unit 1 is also two. The iron block 13 is disc-shaped, and its end face diameter is larger than that of the suction cup electromagnet 22. The thickness of the iron block 13 is at least more than 10 mm, which can ensure the normal suction force of the suction cup electromagnet 22.

[032] In a specific embodiment, the projected shape of the floating body 3 on the horizontal plane is close to a square, and four loading ports 31 penetrating through the upper surface and the lower surface are formed on the floating body 3. The four loading ports 31 are arranged in a tian-shape. A wire through hole 32 is formed in the center of the floating body 3, and the lead of each suction cup electromagnet 22 passes through the wire through hole 32 and is electrically connected with the control box 6. The battery in the battery tank 5 is electrically connected with the control box 6.

[033] A control panel is arranged in the control box 6, and the control panel controls the power-on and power-off of each suction cup electromagnet 22 through relays. In this embodiment, the control panel can be implemented by a microcontroller, a time delay relay, a mechanical timing device, etc., without depending on specific software or involving improvement of the method.

[034] In this embodiment, the control box 6 is used to control the electromagnet stoppers 2 at the bottom of each box unit 1 to disengage according to a predetermined time interval, so as to release one kind of live bait feed from each box unit in order to realize feeding action.

[035] The box unit 1 is limited in its position in the horizontal direction by the load port 31 adapted to it. The clamping mechanism 4 arranged around the loading port 31 limits its vertical displacement. In this embodiment, two clamping mechanisms 4 are arranged around each loading port 31, and the two clamping mechanisms 4 are respectively located at two sides of the box unit 1.

[036] The clamping mechanism 4 comprises a vertical fixing part 41 and a clamping part 42. The vertical fixing part 41 isfixedly arranged along the vertical direction, and the clamping part 42 is strip-shaped and is arranged on one side of the vertical fixing part 41 adjacent to the box unit 1. The bottom end of the clamping part 42 is connected with the vertical fixing part 41 in a hinged manner. The clamping part 42 is used for passing through the clamping port 12 on the side of the box unit 1 to limit the vertical movement of the box unit 1.

[037] In a specific embodiment, the vertical fixing part 41 and the clamping part 42 are both made of channel steel, and they are hinged by a hinge shaft 43, and the clamping part 42 can rotate around the hinge shaft 43. As shown in Fig. 5, it is a schematic diagram that the clamping part 42 is clamped in the clamping port 12. At this time, the bottom end of the clamping part 42 serves as a limiting structure between the vertical fixing part 41 and the clamping part 42 to limit the deflection angle of the top end of the clamping part 42 toward the side of the box unit 1.

[038] In some embodiments, the control box 6 is fixedly mounted above the floating body 3 through a plurality of support rods 7 arranged in the vertical direction. By increasing the erection height of the control box 6, the probability of water ingress can be reduced. Avoid damage to electronic components caused by water ingress. In order to prevent the electromagnet stopper 2 from sinking to the bottom after being separated from the box unit 1, the electromagnet stopper 2 is connected with the support rod 7 through a traction rope. The length of the traction rope is shorter than that of the wire, so that when the traction rope extends to the maximum length, the wire with the electromagnet stopper 2 is still in a relaxed state.

[039] In some embodiments, the floating body 3 is provided with two battery tanks 5, one of which serves as a standby battery slot for supplying power to the control box 6. Round comers 33 around and on the floating body 3.

[040] The use process of the live bait feeding device in this embodiment includes the following steps:

[041] 1. Complete the installation of the box unit 1: keep the clamping part 42 in a vertical state, and then put the box unit 1 into the corresponding loading port 31. When the clamping port 12 on the side of the box unit 1 is flush with the top end of the clamping part 42, the clamping part 42 is pulled to be locked into the clamping port 12 to restrict the box unit 1 from moving downwards.

[042] 2. Turn on the power switch, and energize the electromagnet stopper 2 to obtain magnetism. The two suction cup electromagnets 22 of the electromagnet stopper 2 are aligned with the two round iron blocks 13 at the bottom of the box unit 1, so that the electromagnet stopper 2 blocks the feeding port 11 at the bottom of the box. Then, one end of the traction rope is tied to the steel bar, and the other end is tied to the electromagnet stopper 2. Then, put live bait to be put into the box unit 1.

[043] 3. When the predetermined time point is reached, the control panel controls the corresponding suction cup electromagnet 22 to be powered off, and the magnetism disappears after the suction cup electromagnet 22 is powered off, so that the electromagnet stopper 2 falls off, and the live bait feed in the box unit 1 enters the water outside the box unit 1 through the feeding port 11, thereby feeding the fish.

[044] In this embodiment, the box unit 1 is opened every 12 hours, and the live bait feeding device can be used for 48 hours after being filled once. According to the invention, the electromagnet can be controlled to turn on and off by the control panel, so that the live bait feed can be automatically fed at different time points, the feeding times are reduced, the human capital is saved, and time and labor are saved.
