DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figures 1-4As shown in the figure, the present utility model provides a technical solution: a feeding device for crab farming, including a floating block 1 and a feed bin 2. The feed bin 2 is located above the floating block 1, and a mask 3 is fixedly connected to the bottom of the inner cavity of the feed bin 2. A feeding mechanism 4 is arranged above the floating block 1;

[0029] The feeding mechanism 4 includes a frustum 41, a driving motor 42 and a conveying assembly 47. A large turntable 43 and a small turntable 44 are respectively arranged between the frustum 41 and the feed bin 2. A support rod is fixedly connected between the bottom of the frustum 41 and the top of the floating block 1, and the driving motor 42 is fixedly installed on the outer walls of the three support rods through a motor bracket. The support rod mainly plays a supporting role, and the driving motor 42 is the power source, mainly to provide power for the whole device. The output end of the driving motor 42 is fixedly connected to a rotating shaft 46 through a coupling. The other end of the rotating shaft 46 sequentially penetrates the bottom of the large turntable 43, the bottom of the small turntable 44, the bottom of the feed bin 2 and the top of the inner cavity of the mask 3 and extends upward. A driving bevel gear 45 is arranged inside the mask 3. The number of the conveying assemblies 47 is three, and the three conveying assemblies 47 are equidistantly distributed around the feed bin 2;

[0030] The conveying assembly 47 includes a cylinder 471 and a support frame 475. Inside the cylinder 471, there is a screw conveyor 472. One end of the cylinder 471 away from the support frame 475 is communicated with the feed bin 2, which facilitates the rotation of the screw conveyor 472 to drive the feed in the feed bin 2 into the cylinder 471. One end of the screw conveyor 472 is rotationally connected to the inner wall of the inner cavity of the cylinder 471 through a bearing. The other end of the screw conveyor 472 penetrates the outer wall of the mask 3 and extends into the inner cavity of the mask 3. And a driven bevel gear 473 is fixedly connected to the outer wall of the screw conveyor 472 located inside the mask 3. An outlet hole 474 is opened at the bottom of the inner cavity of the cylinder 471. The large turntable 43 and the small turntable 44 are both fixedly sleeved on the outer wall of the rotating shaft 46, and the two outlet holes 474 are respectively directly above the edges of the large turntable 43 and the small turntable 44. One end of the support frame 475 is fixedly connected to the outer wall of the cylinder 471, and the other end of the support frame 475 is fixedly connected to the outer wall of the floating block 1. The support frame 475 mainly plays a supporting role between the cylinder 471 and the floating block 1, enhancing the firmness of the cylinder 471. Due to the different radii of the large turntable 43 and the small turntable 44, when they rotate simultaneously, the magnitudes of the centrifugal forces generated are also different, so the forces acting on the feed falling from the outlet hole 474 opened at the bottom of the cylinder 471 are also different, causing the feed to be evenly scattered at different distances around the floating block 1. By driving the rotating shaft 46 to rotate through the driving motor 42, the driving bevel gear 45 is driven to rotate, thereby driving the driven bevel gear 473 engaged with the driving bevel gear 45 to rotate, causing the screw conveyor 472 to rotate, so as to convey the feed in the feed bin 2 to the cylinder 471 through the screw conveyor 472. When the feed reaches the two outlet holes 474, it falls on the large turntable 43 and the small turntable 44 with different radii. A stirring blade 5 is fixedly connected to the outer wall of the inner cavity of the feed bin 2 where the rotating shaft 46 is located. By driving the rotating shaft 46 to rotate through the driving motor 42, the stirring blade 5 is driven to rotate, thereby realizing the uniform stirring of the feed in the feed bin 2, eliminating the need to manually mix various feeds before feeding, greatly reducing the labor intensity and improving the efficiency.

[0031] Working principle: The driving motor 42 drives the rotating shaft 46 to rotate, the rotating shaft 46 drives the driving bevel gear 45 to rotate, thereby driving the driven bevel gear 473 engaged with the driving bevel gear 45 to rotate, causing the screw conveyor 472 to rotate, so as to convey the feed in the feed bin 2 to the cylinder 471 through the screw conveyor 472. When the feed reaches the two outlet holes 474, it falls on the large turntable 43 and the small turntable 44 with different radii. Due to the different radii of the large turntable 43 and the small turntable 44, when they rotate simultaneously, the magnitudes of the centrifugal forces generated are also different, so the forces acting on the feed falling from the outlet hole 474 opened at the bottom of the cylinder 471 are also different, causing the feed to be evenly scattered at different distances around the floating block 1, thereby improving the working efficiency and preventing crabs from scrambling for food.

[0032] The driving motor 42 drives the rotating shaft 46 to rotate, thereby driving the stirring blade 5 to rotate, so as to realize the uniform stirring of the feed in the feed bin 2. There is no need to mix various feeds manually before feeding, which greatly reduces the labor intensity and improves the efficiency.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
