[0019] Example

[0020] like Figure 1-3As shown in the figure, in this embodiment, a feeding device for fishery farming is mainly disclosed, including a floating platform mounting plate 1. There is a floating cylinder 10 below the floating platform mounting plate 1. A fixed cylinder 2 is installed at the center of the floating platform mounting plate 1. A feeding hopper 20 is provided at the top of the fixed cylinder 2. The bottom of the fixed cylinder 2 is coaxially and rotatably connected to a rotating cylinder 3. A feeding port 30 is opened at the lower end of the circumference of the rotating cylinder 3. A motor 4 is coaxially arranged at the top of the fixed cylinder 2. The motor 4 is connected to a driving shaft 41 through a coupling. The bottom end of the driving shaft 41 is fixed to the inner wall of the bottom end of the rotating cylinder 3. A driven shaft 43 is sleeved on the driving shaft 41 in a transmission manner. The driven shaft 43 is coaxially arranged inside the fixed cylinder 2. Stirring rods 44 radially extend from the driven shaft 43. Specifically, the floating cylinders 10 are evenly installed below the floating platform mounting plate 1, so that the floating platform mounting plate 1 floats stably on the water surface. The feeding port 30 is above the water surface. The lower end of the fixed cylinder 2 is fixedly connected to the floating platform mounting plate 1. The upper part of the rotating cylinder 3 is inserted into the lower end inside the fixed cylinder 2 and is rotationally clamped. The lower part of the rotating cylinder 3 is below the floating platform mounting plate 1. Under the rotational output of the motor 4, the driving shaft 41 drives the rotating cylinder 3 to rotate. The driving shaft 41 drives the driven shaft 43 to rotate. Feed is added from the feeding hopper 20 into the fixed cylinder 2. Under the stirring action of the stirring rods 44 driven by the driven shaft 43, the feed is stirred and mixed, effectively eliminating caking and making the feed evenly mixed. Then the feed falls into the rotating cylinder 3 and is thrown out from the feeding port 30 under the action of rotational centrifugal force, improving the uniformity of feeding.

[0021] Furthermore, in specific implementation, in the above-mentioned embodiment provided by the present utility model, the driving shaft 41 and the driven shaft 43 are concentrically arranged. A driving gear 410 is clamped on the driving shaft 41. Internal teeth 430 are provided on the inner wall of the driven shaft 43. A middle shaft 42 fixed to the inner top end of the fixed cylinder 2 is parallelly arranged between the driving shaft 41 and the driven shaft 43. An intermediate gear 420 that is meshed and connected to both the driving gear 410 and the internal teeth 430 is rotatably sleeved on the middle shaft 42. Specifically, sealing end caps are provided at both the upper and lower ends of the driven shaft 43 and are rotatably connected to the driving shaft 41, which can effectively prevent feed from entering the inside of the driven shaft 43. The driving shaft 41 is a smooth rod. An external gear driving gear 410 with M teeth is clamped on its upper part through a protrusion. N internal teeth 430 are provided on the inner wall of the driven shaft 43, and M < N. Through the transmission of the intermediate gear 420, the driving shaft 41 and the driven shaft 43 form a coaxial differential rotation structure. The rotation speed of the driving shaft 41 is greater than the rotation speed of the driven shaft 43. When the driving shaft 41 rotates one circle, the driven shaft 43 rotates M / N circles. The output rotation speed of the motor 4 should ensure that the rotating cylinder 3 can fully throw out the feed and avoid the rotation speed of the driven shaft 43 being too fast, causing the feed to be thrown onto the inner wall of the fixed cylinder 2 too much, forming accumulated material blockage, and ensuring that the feed can smoothly fall from the fixed cylinder 2 into the rotating cylinder 3.

[0022] Furthermore, in a specific implementation, an annular groove 21 is provided on the lower inner wall of the fixed cylinder 2 provided in the embodiment of the utility model, and the top of the rotating cylinder 3 is rotatably engaged in the annular groove 21. Specifically, a protrusion extending toward the circumference is provided on the top of the rotating cylinder 3, and the protrusion is limitedly engaged in the annular groove 21 to realize the rotational connection between the rotating cylinder 3 and the fixed cylinder 2. A wear-resistant layer can also be provided between the rotating cylinder 3 and the fixed cylinder 2 to improve wear resistance and service life.

[0023] Furthermore, in a specific implementation, the bottom of the rotating drum 3 provided in the embodiment of the utility model is conical, and the top of the cone is welded to the bottom end of the driving shaft 41, and the lower edge of the cone is smoothly connected to the feeding port 30, which facilitates the sliding of feed to the feeding port 30, reduces the feed residue in the rotating drum 3, and ensures sufficient feeding.

[0024] Furthermore, in a specific implementation, the bottom of the fixed cylinder 2 provided in the embodiment of the utility model is a funnel-shaped opening, and is aligned and connected with the top of the rotating cylinder 3, ensuring that the feed can slide smoothly from the fixed cylinder 2 into the rotating cylinder 3, reducing the feed residue in the fixed cylinder 2.

[0025] Furthermore, in a specific implementation, the above-mentioned feeding ports 30 provided in the embodiment of the utility model are evenly arranged along the circumference of the rotating drum 3, so as to facilitate the rapid and uniform feeding of feed.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
