[0048] Example 1

[0049] The present application embodiment discloses an automatic production line for aquatic feed. Figure 1 and Figure 2 An automatic production line for aquatic feed includes a batching device, a mixing device, a crushing device, a granulating device, a screening device and a packaging device which are arranged in sequence. The batching device adopts a variety of methods. The raw materials that do not need to be crushed directly enter the batching bin after magnetic separation. The raw materials that need to be crushed are crushed by a hammer powder machine or a water drop hammer crusher, and finally enter the batching bin together. The mixing device is used to mix and screen the crushed materials. The granulating device adopts a granulator for granulation, and it also needs to be matured and cooled later. Finally, the screening device performs screening and grading, and the finished products are packaged.

The sorting mechanism is used to screen the materials. When the powder coming out of the sorting mechanism falls into the mixing box 1, since the mixing box 1 is a closed setting, the raw materials falling into the mixing box 1 are transported to the next process by suction. Multiple extraction ports can be set in the mixing box 1 to ensure that the raw materials in the mixing box 1 are fully extracted.

[0051] In order to realize the self-rotation of the rotating rod 4, the transmission assembly includes an internal gear 29 and multiple external gears 30. In this embodiment, three rotating rods 4 are selected, and three external gears 30 are also selected. The external gear 30 is fixedly connected to the bottom end of the rotating rod 4, and the internal gear 29 is fixedly connected to the inner wall of the mixing box 1. The rotating rod 4 and the rotating disk 2 are rotatably connected through a bearing sleeve. In addition, the rotating disk 2 and the mixing box 1 are rotatably connected through a rotating shaft, and the end of the rotating shaft extends out of the mixing box 1. The driving member 3 is coaxially fixed with the bottom end of the rotating shaft. The driving member 3 can be a motor. Therefore, when the driving member 3 controls the rotation of the rotating shaft, the rotating shaft drives the rotating disk 2 to rotate, and the rotating disk 2 drives the rotating rod 4 to rotate. At this time, the outer gear 30 and the internal gear 29 move relative to each other, and the rotating rod 4 rotates, thereby realizing the self-rotation effect of the rotating rod 4.

[0052] Reference Figure 3 and Figure 4 The sorting mechanism includes a base 5 fixedly mounted on the rotating rod 4, a sorting barrel 6 fixedly connected to the base 5, a filter cartridge 7 installed in the sorting barrel 6, a sorting piece 8 movably arranged on the sorting barrel 6, and an adjustment component for realizing that the sorting piece 8 is away from the sorting barrel 6. The sorting barrel 6 is provided with a plurality of sorting ports 9, the sorting piece 8 is adapted to the sorting port 9, and the two sides or four sides of the sorting piece 8 are set as inclined surfaces, and the two sides or four sides of the sorting port 9 are adapted to the side surfaces of the sorting piece 8, which is used to increase the contact area between the sorting piece 8 and the sorting port 9, to ensure that when the sorting piece 8 moves to the sorting port 9, the sealing between the sorting piece 8 and the sorting barrel 6 is better, and sealing strips are also provided on both sides of the sorting piece 8, or sealing strips are provided at the contact positions between the sorting piece 8 and the sorting port 9, thereby achieving a further sealing effect.

[0053] The sorting barrel 6 is closed, and the top cover of the sorting barrel 6 is detachable. In this embodiment, it is locked by means of a buckle or a lock. The mesh number of the filter cartridge 7 is determined according to actual needs. In addition, both ends of the filter cartridge 7 are open. The filter cartridge 7 is welded to the inner wall of the sorting barrel 6. Spot welding can be used. The outer wall of the filter cartridge 7 fits the inner wall of the sorting barrel 6. The adjustment component includes a power part 10, a double-headed threaded rod 11 rotatably connected to the base 5, two sliders 12 respectively screwed with the two ends of the double-headed threaded rod 11, and a slider fixed to the sorting piece 8. The connected sorting rod 13 and the limiting piece, the power piece 10 can also use a motor like the driving piece 3, the power piece 10 is installed in the base 5, the power piece 10 is used to drive the double-headed threaded rod 11 to rotate, the base 5 is provided with a cavity for installing the double-headed threaded rod 11 and the power piece 10, both ends of the double-headed threaded rod 11 are rotatably connected to the base 5, the side of the sorting piece 8 away from the sorting barrel 6 is fixedly connected to the sorting rod 13, the slider 12 is fixedly connected to the other end of the sorting rod 13, and the limiting piece is used to limit the rotation of the slider 12.

[0054] The limiting rod is set as a slide rod 14, which is fixedly connected to the base 5, and the slide rod 14 is set parallel to the double-headed threaded rod 11. The slider 12 is sleeved and slides outside the slide rod 14. When the power part 10 controls the rotation of the double-headed threaded rod 11, the rotation of the slider 12 is restricted by the slide rod 14, and the slide rod 14 can only slide along the length direction of the slide rod 14. The two sliders 12 move closer to or away from each other under the control of the double-headed threaded rod 11, thereby realizing the movement of the sorting piece 8 toward the sorting barrel 6 or away from the sorting barrel 6, thereby realizing the switching effect of the mixing and screening functions.

[0055] When stirring is required, the rotating rod 4 is controlled to rotate. At this time, the sorting pieces 8 are attached to the sorting barrel 6, and the raw materials are fully mixed in the sorting barrel 6. When the raw materials need to be screened, the double-headed threaded rod 11 is controlled to rotate. At this time, the two sorting pieces 8 are away from the sorting barrel 6. At this time, if the sorting barrel 6 continues to rotate with the rotating rod 4, the raw materials in the sorting barrel 6 are subjected to the centrifugal force and begin to be screened. The large-sized raw materials still remain in the sorting barrel 6, and the powder that meets the size enters the mixing box 1 and is extracted, thereby achieving the screening effect of the material.

[0056] Reference Figure 3 and Figure 4When the screening work is completed, the collecting mechanism is used to collect raw materials that do not meet the size. The collecting mechanism includes a discharge pipe 15, a solenoid valve installed on the discharge pipe 15, a collection box 16 movably arranged in the base 5, and a material receiving assembly arranged in the collection box 16. The base 5 is provided with a cavity for accommodating the discharge pipe 15. The collecting mechanism is located above the double-headed threaded rod 11 in the base 5. The discharge pipe 15 is connected to the bottom opening of the sorting barrel 6. The solenoid valve is used to control the discharge. The base 5 is provided with a slot 17 for placing the collection box 16. Either end of the slot 17 is open. The slot 17 is connected to the cavity. The opening of the discharge pipe 15 is opposite to the upper opening of the collection box 16.

[0057] Reference Figure 3 and Figure 4 The material collecting assembly facilitates the removal of non-standard materials. It includes a collection bag 18, multiple fixing posts 19 detachable from the open end of the collection box 16, multiple fixing rings 20 disposed at the opening of the collection bag 18, and a clamping plate 21 for clamping the fixing rings 20 to the collection box 16. The collection bag 18 is sleeved within the collection box 16, with the open end of the collection bag 18 folded over the opening of the collection box 16, like a garbage bag sleeved within a garbage can. Furthermore, the collection box 16 and the base 5 are fixedly connected to one end near the opening of the slot 17 with plug rings 27. Screws 26 are inserted into the two plug rings 27, and nuts 28 are threadedly connected to the ends of the screws 26 away from the heads. The screws 26 and nuts 28 cooperate to lock the collection box 16 and the base 5.

[0058] Reference Figure 5 and Figure 6 In this embodiment, four fixing rings 20 and four fixing columns 19 are selected. The fixing ring 20 and the collection bag 18 are bonded together, and the top of the fixing column 19 is fixedly connected to the clamping disk 21. The end face size of the clamping disk 21 is larger than the outer diameter size of the fixing ring 20, and the end face size of the fixing column 19 is smaller than the inner diameter size of the fixing ring 20, ensuring that the fixing ring 20 is located between the clamping disk 21 and the end face of the collection box 16.

[0059] The outer wall of the fixing column 19 is fixedly connected with a protrusion 22, and the corresponding position of the collection box 16 is provided with a fixing hole 23 for the fixing column 19 to be plugged in. The outer wall of the fixing column 19 is fixedly connected with a protrusion 22, and the corresponding position of the collection box 16 is provided with a fixing hole 23 for the fixing column 19 to be plugged in. The side wall of the fixing hole 23 is provided with a slide groove 24 for the sliding of the protrusion 22. The side wall of the fixing hole 23 is provided with an arc groove 25 at the bottom end side wall of the slide groove 24. The other end of the arc groove 25 is closed. The cross-sectional circle of the fixing hole 23 where the cross-sectional arc is located is arranged to be co-centered. When the fixing post 19 is inserted into the fixing hole 23, the protrusion 22 moves into the slide groove 24, driving the fixing post 19 to rotate. The fixing post 19 drives the protrusion 22 to rotate into the arc groove 25. At this time, the movement of the fixing post 19 away from the collection box 16 is restricted. At this time, the clamping plate 21 moves to a position abutting against the fixing ring 20. The fixing ring 20 is restricted on the collection box 16, thereby achieving the fixing effect of the collection bag 18.

[0060] The implementation principle of an automatic production line for aquatic feed in an embodiment of the present application is as follows: when raw materials need to be mixed, the sorting sheet 8 is fitted with the sorting drum, the driving part 3 controls the rotation of the rotating disk 2, and the rotating disk 2 drives the rotating rod to rotate. Under the relative movement of the inner gear 29 and the outer gear 30, the self-rotation and revolution effects of the sorting drum are realized, thereby achieving the mixing effect of the raw materials.

[0061] When screening is required, the power part 10 drives the double-headed threaded rod 11 to rotate, and the double-headed threaded rod 11 controls the movement of the slide bar 14. Under the restriction of the slide bar 14, the slider 12 drives the sorting rod 13 to move, and the sorting rod 13 drives the sorting piece 8 to separate from the sorting barrel 6. At this time, under the action of the filter cartridge 7, the screening effect of the raw materials is achieved. In addition, through the self-rotation effect of the sorting barrel 6, the screening effect of the raw materials is achieved at this time, and the solenoid valve is controlled. Raw materials that do not meet the size enter the collection bag 18. After the work is completed, the collection box 16 is pulled out of the slot 17, the fixed column 19 is separated from the collection box 16, and the collection bag 18 is taken out of the collection box 16, and the raw materials in the collection bag 18 are crushed again.
