[0022] like Figure 1As shown, the utility model is an automatic feeding device for an unmanned shrimp feeding boat, comprising a base 2 located on the upper part of a hull 1, and the base 2 is connected to the hull 1 through a plurality of fixed brackets. The upper part of the base 2 is connected to a silo 3 through a plurality of first support columns 201, and the silo 3 is used to store bait. The silo 3 is provided with an inverted trapezoidal discharge portion 301, and the discharge portion 301 is provided with a slot for feeding the bait. The hull 1 in this embodiment adopts a two-stage inflatable buoy and a propeller power system, and the hull 1 is also equipped with a control system and a power system.

[0023] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the lower end of the silo 3 is connected to a feeding mechanism 4, which is used to transfer the bait in the silo 3. The feeding mechanism 4 includes a feeding motor 401 located at the upper part of the base 2 and a spiral auger 402 connected to the output end of the feeding motor 401. The outer periphery of the spiral auger 402 is provided with a feeding sleeve 403, the feeding sleeve 403 is fixed to the upper part of the base 2, and the upper tube wall of the feeding sleeve 403 is provided with a feeding slot 404, the feeding slot 404 is correspondingly connected to the slot of the lower material part 301, and the feeding motor 401 drives the spiral auger 402 to transfer the bait from the feeding slot 404 along the feeding sleeve 403. The feeding motor 401 and the swing motor 701 and the steering motor 801 described below are all reduction motors and are electrically connected to the power system of the hull 1.

[0024] In a preferred embodiment, a fan 5 fixed on the upper part of the base 2 is provided on one side of the feeding mechanism 4, and an air inlet pipe 502 is connected to the air outlet 501 of the fan 5, and the air inlet pipe 502 is not parallel to the feeding sleeve 403. Preferably, the angle between the air inlet pipe 502 and the feeding sleeve 403 is less than 45 degrees, so that the wind force of the air inlet pipe 502 can blow the bait forward in time and forcefully. The feeding sleeve 403 is connected to two ports near one end of the air inlet pipe 502, and is connected to the feeding pipe 6 located on the upper part of the base 2, and the feeding pipe 6 is connected and fixed by the fixing plate 203 located on the upper part of the base 2. Therefore, the feeding sleeve 403, the air inlet pipe 502 and the feed pipe 6 form a bait conveying pipeline similar to a Y-shaped structure. The feeding motor 401 drives the spiral auger 402 to rotate, and the spiral auger 402 evenly conveys the bait to the three-way intersection of the Y-shaped bait conveying pipeline. The wind force output by the fan 5 blows the bait out of the feed pipe 6 to the feeding pipe 9, thereby realizing the function of automatic feeding of shrimps, and the feeding is relatively uniform.

[0025] In a preferred embodiment, the feeding pipe 6 is provided with a parallel discharge end 601, one side of the discharge end 601 is connected to a bellows 602, and the side of the bellows 602 away from the discharge end 601 is connected to a feeding pipe 9, and the bellows 602 can support the feeding pipe 9 to rotate at a certain angle to adapt to the feeding work of a larger area.

The upper part of the driven gear 803 is fixedly connected to the second rotating column 804, and the driving gear 802 is meshed with the driven gear 803. As a result, the steering motor 801 drives the driving gear 802 and the driven gear 803 to rotate, and then the second rotating column 804 and the fixed ring 805 rotate, driving the feeding pipe 9 to rotate in the horizontal direction to adjust the feeding direction and feeding area of ​​the feeding pipe 9.

[0026] Under normal circumstances, the normal feeding of bait is completed by the spiral auger 402, because the rotating spiral auger can "twist" the bait in the slot. In order to prevent part of the bait from being attached to the side wall of the feeding part 301 due to friction, Figure 2 As shown, in a preferred embodiment, a swing component 7 is provided on one side of the silo 3 to knock the unloading part 301, and the swing component 7 swings and knocks the wear-resistant plate 302 located on one side of the unloading part 301 to promote the normal unloading of bait. The swing component 7 includes a swing motor 701 located on the upper part of the base 2, and the swing motor 701 is supported by the fixed plate 203 on the upper part of the base 2. The output end of the swing motor 701 is connected to a turntable 702, and the radial outer wall of the turntable 702 is provided with one or more swing columns 703. The swing column 703 can continuously knock the wear-resistant plate 302 and continuously vibrate the unloading part 301 to facilitate the normal falling of the bait.

[0027] Such as 1 and Figure 4As shown, in a preferred embodiment, the feeding pipe 9 is further provided with a bell mouth 901 at one end away from the bellows 602, and one or more second support columns 902 are provided in the bell mouth 901. The second support columns 902 are radially arranged in the bell mouth 901, and a material distribution part 903 is provided at the middle position of the second support column 902 on one side facing the bellows 602, so that the transported bait can be uniformly thrown out along the axial direction and side wall of the bell mouth 901, and its feeding area is larger and more uniform. Preferably, the material distribution part 903 is a conical structure, and the tip of the cone faces the direction of the bellows 602, and the bait transported by wind is evenly dispersed at the position of the material distribution part 903.

[0028] like Figure 1 and Figure 5 As shown, in a preferred embodiment, the discharge end 601 is rotatably connected with a first rotating column 603, and the first rotating column 603 is rotatably connected to the inner wall of the discharge end 601 through a bearing 604. The first rotating column 603 is provided with a plurality of conical thorn portions 605 in an axial and radial array. When the bait passes through the first rotating column 603 and the conical thorn portion 605, the first rotating column 603 rotates clockwise or counterclockwise, or does not rotate. At this time, the conical thorn portion 605 can break up the bait transmitted through the feed pipe 6, and the broken up bait is more evenly distributed when it is thrown out from the feeding pipe 9.

[0029] When the utility model is in use, first, the hull 1 controls the hull 1 to cruise autonomously according to the path planned by the control system and the operating waters in the shrimp field; when arriving at the feeding area, the control system starts the feeding mechanism 4 to transport the bait in the silo 3 to one end of the feeding pipe 6, and starts the fan 5 so that the wind force in the air inlet pipe 502 transfers the bait from the feeding pipe 6 to the feeding pipe 9, and the feeding pipe 9 continues to feed, and the steering component 8 can be started according to actual needs, and the steering component 8 controls the feeding direction of the feeding pipe 9; at the same time, during the feeding process, the swing component 7 continuously knocks the unloading end 301 at the lower part of the silo 3 to promote the smooth falling of the bait. After the feeding is completed, the current position is recorded, and the feeding is continued after the bait is replenished.

[0030] The preferred specific implementation modes and embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation modes and embodiments, and various changes or equivalent substitutions can be made within the knowledge scope of those skilled in the art without departing from the concept of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the utility model.
