Description

Technical Field

[0001] This utility model belongs to the technical field of aquaculture equipment, and specifically relates to a feed preparation device for crab seedling farming. Background Technology

[0002] Crab larvae farming feed preparation device is a mechanical equipment or system specifically used to mix, adjust and process various feed ingredients (including biological feed, artificial feed, additives, etc.) in a certain proportion into feed suitable for crab larvae to eat.

[0003] Traditional crab larvae farming feed mixing devices involve pouring various proportions of feed into a mixing tank and then mixing them using a stirring method. However, the stirring rod is usually a long rod, which results in insufficient shear force during the mixing process, requiring more time to mix. Furthermore, the feed tends to pile up when added, further increasing the difficulty of mixing and thus increasing the mixing time, leading to low overall mixing efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a feed mixing device for crab seedling farming, which enables uniform mixing of feed and improves mixing efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A feed preparation device for crab seedling farming includes a preparation tank, a feeding hopper, a support frame, and a collection trough;

[0007] The mixing barrel is equipped with a feeding hopper at the top and a support frame and a collection trough at the bottom;

[0008] The feed hopper has a conical shell in the middle, and the conical shell is fixed to the inner wall of the mixing barrel by several connecting rods. The edge of the conical shell is separated from the inner wall of the mixing barrel, and the space between adjacent connecting rods forms a discharge port. The top of the conical shell is equipped with a servo motor, which is powered by an external power source.

[0009] The output end of the servo motor passes through the conical shell into the mixing barrel and is connected to a rotating rod via a coupling; the main body of the rotating rod is provided with several stirring rods, and several dispersing strips are provided at equal intervals at the bottom of the stirring rods.

[0010] The mixing barrel has a guide plate along its circumference at the bottom of its inner wall, and the guide plate is at an angle of 30°-45° to the horizontal plane; the bottom of the mixing barrel is also provided with a discharge chute.

[0011] The working principle of this utility model is as follows:

[0012] During use, various pre-mixed feeds are sequentially fed into the hopper. After falling onto the conical shell, the feed disperses and drops into the mixing tank through the discharge port, reducing accumulation. Once all feed has been added, the servo motor is activated, driving the rotating rod to rotate, which in turn rotates the stirring rod to mix the feed. Simultaneously, the dispersing strips at the bottom of the stirring rod further disperse and mix the feed, increasing the shear force during mixing and preventing clumping and blockage, thus achieving efficient mixing. A guide plate at the bottom of the mixing tank directs the mixed feed towards the discharge port, preventing feed residue from accumulating in hard-to-drain corners. The mixed feed is then discharged from the bottom of the mixing tank into the collection trough.

[0013] As a further improvement of this utility model, the inner wall of the mixing barrel is provided with several rows of dispersing rods at equal intervals, with 4-6 dispersing rods in each row.

[0014] The mixing tank has several dispersing rods on its inner wall to further disperse the feed being mixed by the stirring rod, preventing it from piling up and clumping, thus making the feed mix more thoroughly and improving the feed mixing efficiency.

[0015] As a further improvement of this utility model, the bottom of the mixing barrel is provided with several discharge holes, and the bottom of the mixing barrel is connected to a turntable through a rotating shaft. The main body of the turntable is provided with discharge holes that are the same in shape and number as the discharge holes. The turntable is set in the discharge trough, and the turntable is provided with handles around its body. The discharge trough is provided with limiting grooves around its body for placing the handles.

[0016] A turntable is installed at the bottom of the mixing tank. The discharge speed can be adjusted by turning the handle to rotate the turntable and thus adjusting the interval between the discharge hole and the feed hole.

[0017] As a further improvement of this utility model, the servo motor is provided with a protective cover, and the protective cover is connected to the inner wall of the feed hopper by a fixing rod.

[0018] The protective cover can prevent feed powder from entering the servo motor and causing accidents.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model sets a conical shell on the top of the mixing tank, pre-disperses the feed added to the tank, and then disperses and mixes the feed together with several stirring rods, dispersing rods and dispersing rods on the tank wall. This can effectively avoid the problem of feed accumulating and clumping due to insufficient shear force, and achieve efficient and uniform mixing.

[0021] 2. This utility model can effectively control the discharge speed by setting a turntable at the bottom of the mixing tank and adjusting the interval between the discharge hole and the feed hole by rotating the turntable. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are all conventional technical means in the art. Example

[0029] like Figure 1-3 The feed preparation device for crab seedling farming shown includes a preparation tank 1, a feeding hopper 2, a support frame 5, and a collection trough 6.

[0030] The mixing barrel 1 is equipped with a feeding hopper 2 at the top and a support frame 5 and a collection trough 6 at the bottom;

[0031] The feed hopper 2 has a conical shell 3 in the middle, and the conical shell 3 is fixed to the inner wall of the mixing barrel 1 by several connecting rods 9. The edge of the conical shell 3 is separated from the inner wall of the mixing barrel 1, and the space between adjacent connecting rods 9 forms a discharge port 22. The top of the conical shell 3 is equipped with a servo motor 8, which is powered by an external power source.

[0032] The output end of the servo motor 8 passes through the conical shell 3 to the inside of the mixing barrel 1, and is connected to the rotating rod 10 through a coupling; the main body of the rotating rod 10 is provided with a number of stirring rods 11, and a number of dispersing strips 12 are provided at equal intervals at the bottom of the stirring rod 11.

[0033] The mixing barrel 1 has a guide plate 14 at the bottom of its inner wall and around its perimeter, and the guide plate 14 is at a 30° angle to the horizontal plane; the bottom of the mixing barrel is also provided with a discharge chute 17.

[0034] The working principle of this embodiment is as follows:

[0035] In use, various pre-mixed feeds are sequentially introduced into the feed hopper 2. After falling onto the conical shell 3, the feeds disperse and drop into the mixing tank 1 through the discharge port 22, thus reducing accumulation. Once the feeds are added, the servo motor 8 is activated to drive the rotating rod 10 to rotate, which in turn causes the stirring rod 11 to rotate and mix the feed. Simultaneously, the dispersing strips 12 located at the bottom of the stirring rod 11 rotate with the stirring rod 11 to further disperse and mix the feed, thereby increasing the shear force during feed mixing and preventing feed accumulation and clumping that could lead to blockages, thus achieving efficient feed mixing. A guide plate 14 is installed at the bottom of the mixing tank 1 to backflow the mixed feed towards the discharge port, preventing feed residue from remaining in corners at the bottom of the tank that are difficult to discharge. The mixed feed is then discharged from the bottom of the mixing tank 1 into the collection trough 6. Example

[0036] This embodiment is a further improvement based on Embodiment 1, as detailed below:

[0037] like Figure 2 As shown, the inner wall of the mixing barrel 1 is provided with several rows of dispersing rods 13 at equal intervals, with 4 dispersing rods 13 in each row.

[0038] The working principle of this embodiment is the same as that of embodiment 1. Several dispersing rods 13 are provided on the inner wall of the mixing tank 1 to further disperse the feed that is being mixed by the stirring rod 11, so as to prevent it from piling up and clumping, making the feed more fully mixed, thereby improving the feed mixing efficiency. Example

[0039] This embodiment is a further improvement based on embodiment 2, as detailed below:

[0040] like Figure 2 , 4 As shown in Figure 5, the bottom of the mixing barrel 1 is provided with a plurality of discharge holes 16. The bottom of the mixing barrel 1 is connected to a turntable 20 via a rotating shaft 15. The main body of the turntable 20 is provided with discharge holes 21 that are the same in shape and number as the discharge holes 16. The turntable 20 is set in the discharge trough 17. The turntable 20 is provided with handles 19 around its periphery. The discharge trough 17 is provided with limiting grooves 18 around its periphery for placing the handles 19.

[0041] The aforementioned dispersing rods 13 are arranged in rows of 4.

[0042] The deflector 14 is at a 45° angle to the horizontal plane.

[0043] The working principle of this embodiment is the same as that of embodiment 2. A turntable 22 is set at the bottom of the mixing tank 1. The turntable 22 can be rotated by rotating the handle 19, thereby adjusting the interval between the discharge hole 21 and the feeding hole 16 to adjust the discharge speed. Example

[0044] This embodiment is a further improvement based on embodiment 3, as detailed below:

[0045] The servo motor 8 is provided with a protective cover 7, and the protective cover 7 is connected to the inner wall of the feed hopper 2 by a fixing rod 4.

[0046] Five of the aforementioned dispersing rods 13 are arranged in each row.

[0047] The deflector 14 is at a 40° angle to the horizontal plane.

[0048] The working principle of this embodiment is the same as that of embodiment 3. The protective cover 7 can prevent feed powder from entering the servo motor 8 and causing an accident.
