Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a device for collecting residual feed in cage aquaculture. Background Technology

[0002] In aquaculture, cage culture is widely used as a highly efficient farming method, but the problem of uneaten feed has always been a key factor restricting its sustainable development. Uneaten feed that has not been consumed by fish in the cages not only causes a huge waste of feed resources and increases farming costs, but also accumulates at the bottom of the aquaculture area, gradually decomposing and producing a large amount of harmful substances, disrupting the ecological balance of the aquatic body, leading to water quality deterioration, and consequently affecting the growth and health of farmed fish and increasing the risk of disease.

[0003] However, in order to reduce the pollution of water quality by uneaten feed, existing technologies usually use water pumps to suck out the material from the bottom of the cage. However, due to the large area of ​​the cage, when cleaning the uneaten feed at the bottom of the cage, it is necessary to manually enter the cage and move the suction device to the middle of the cage. This process is difficult and cannot effectively clean the uneaten feed inside the cage. Moreover, it requires a lot of manpower during the cleaning process. Therefore, a cage aquaculture uneaten feed collection device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a device for collecting uneaten feed in net cage aquaculture, in order to solve the problem mentioned in the background art that the material at the bottom of the cage is usually sucked out by a water pump. However, due to the large size of the cage, it is not possible to effectively suck out the material in the middle of the cage, and a lot of manpower is required in the cleaning process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for collecting uneaten feed in cage aquaculture, comprising a device body, four support blocks fixedly connected to the upper surface of the device body, and a second threaded rod rotatably connected to the bottom end of each of two adjacent support blocks. A second sprocket is fixedly connected to one end of each second threaded rod, and the outer surfaces of the two second sprockets are driven by a chain. A second motor is fixedly connected to the back of each support block, and the output end of the second motor is fixedly connected to the end of one of the second threaded rods away from the second sprocket via a coupling. A second limiting frame is threadedly connected between two of the second threaded rods, and the threads inside the two ends of the second limiting frame are respectively... The two second threaded rods are adapted to the threads on their outer surfaces. The interiors of the two adjacent support blocks are rotatably connected to first threaded rods. One end of each of the two first threaded rods is fixedly connected to a first sprocket. The outer surfaces of the two first sprockets are driven by a chain. A first motor is fixedly connected to the right side of the support block. The output end of the first motor is fixedly connected to the end of the first threaded rod away from the first sprocket via a coupling. A first limiting frame is threadedly connected between the two first threaded rods. The threads inside the two ends of the first limiting frame are adapted to the threads on the outer surfaces of the two first threaded rods. A cleaning device is provided inside the intersection of the first limiting frame and the second limiting frame.

[0006] Preferably, the cleaning device includes a limiting block, the outer surface of which is slidably connected to the interior of the first limiting frame and the second limiting frame, respectively.

[0007] Preferably, a connecting rod is fixedly connected to the lower surface of the limiting block, and a conical box is fixedly connected to the lower surface of the connecting rod.

[0008] Preferably, a fixing frame is fixedly connected inside the conical box, a third motor is fixedly connected to the lower surface of the fixing frame, and a cleaning block is fixedly connected to the output end of the third motor through a coupling. The lower surface of the cleaning block is in contact with the inner bottom wall of the device body.

[0009] Preferably, a support plate is fixedly connected to one side of the device body, and a water pump is fixedly connected to the upper surface of the support plate. The input end of the water pump is fixedly connected to the upper surface of the limiting block.

[0010] Preferably, a filter box is fixedly connected to the upper surface of the support plate, a collection box is provided inside the bottom of the filter box, a plurality of filter plates arranged linearly are provided inside the top of the filter box, and a guide tube is fixedly connected to the upper surface of the filter box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This cage aquaculture residual feed collection device uses two sets of mutually perpendicular first and second threaded rods, along with cross-set first and second limiting frames, to enable the first and second limiting frames to work together to drive the cleaning device to move precisely at any position on the bottom plane of the cage, ensuring thorough cleaning without dead corners, achieving efficient cleaning of the cage and reducing the labor intensity of workers.

[0012] This cage aquaculture residual feed collection device combines the mechanical cleaning of the cleaning block with the negative pressure suction of the conical box. While the cleaning block is driven by a third motor to rotate and clean the bottom of the cage, the negative pressure generated by the water pump is used to instantly suck up residual feed and other impurities through the conical box. In conjunction with the filter box and collection box with multiple filter plates, the residual feed is collected and filtered. The filtered clean water flows back to the main body of the device through the guide pipe, which not only achieves effective cleaning, separation and collection of residual feed, but also realizes sustainable internal water circulation.

The second motor 11 drives the second threaded rod 9 to rotate. A second limiting frame 14 is threadedly connected between the two second threaded rods 9. The threads inside the two ends of the second limiting frame 14 are respectively connected to the threads on the outer surfaces of the two second threaded rods 9. The two adjacent support blocks 2 are rotatably connected to a first threaded rod 4. One end of each of the two first threaded rods 4 is fixedly connected to a first sprocket 5. The first threaded rods 4 serve to connect and fix the position of the first sprocket 5. The outer surfaces of the two first sprockets 5 are driven by a chain. A first motor 3 is fixedly connected to the right side of the support block 2. The output end of the first motor 3 is fixedly connected to the end of the first threaded rod 4 away from the first sprocket 5 through a coupling. The first motor 3 serves to drive the first threaded rod 4 to rotate. A first limiting frame 12 is threadedly connected between the two first threaded rods 4. The threads inside the two ends of the first limiting frame 12 are adapted to the threads on the outer surfaces of the two first threaded rods 4. The two first threaded rods 4 support and limit the position of the first limiting frame 12. A cleaning device is provided inside the intersection of the first limiting frame 12 and the second limiting frame 14. The first limiting frame 12 and the second limiting frame 14 cooperate to support and limit the cleaning device.

[0016] The cleaning device includes a limiting block 13. The outer surface of the limiting block 13 is slidably connected to the interior of the first limiting frame 12 and the second limiting frame 14. The first limiting frame 12 and the second limiting frame 14 serve to limit the position of the limiting block 13. The first limiting frame 12 and the second limiting frame 14 are arranged vertically, so that when the first limiting frame 12 and the second limiting frame 14 move simultaneously, the limiting block 13 slides inside them, driving the limiting block 13 to move to any position. The limiting block 13 is hollow and can allow water to flow through.

[0017] The lower surface of the limiting block 13 is fixedly connected to a connecting rod 7, and the lower surface of the connecting rod 7 is fixedly connected to a conical box 8. The connecting rod 7 serves to connect the conical box 8 and the limiting block 13. The connecting rod 7 is hollow, allowing water inside the conical box 8 to pass through the connecting rod 7 into the limiting block 13.

[0018] The conical box 8 is internally fixedly connected to a fixing frame 22, and a third motor 20 is fixedly connected to the lower surface of the fixing frame 22. The fixing frame 22 serves to limit and fix the position of the third motor 20. The output end of the third motor 20 is fixedly connected to a cleaning block 21 through a coupling.

[0021] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0022] Working principle: In use, the second motor 11 and the first motor 3 are started respectively, driving the second threaded rod 9 and the first threaded rod 4 to rotate. Simultaneously, the second threaded rod 9 rotates through the chain transmission between the two second sprockets 10, causing the other second threaded rod 9 to rotate, thus moving the second limiting frame 14 back and forth. Similarly, the first motor 3, in conjunction with the first threaded rod 4 and the first sprocket 5, causes the first limiting frame 12 to move left and right. Through the cooperation of the first limiting frame 12 and the second limiting frame 14, the limiting block 13 slides inside the first limiting frame 12 and the second limiting frame 14, allowing the first limiting frame 12 and the second limiting frame 14 to move the limiting block 13 to... The action of any position on the surface of the device body 1 further drives the connecting rod 7 and the conical box 8 to move at the bottom of the device body 1. Then, the third motor 20 is started, which drives the cleaning block 21 to rotate, so that the cleaning block 21 rotates relative to the inner bottom wall of the device body 1, cleaning the inner bottom wall of the device body 1. At the same time, the water pump 19 is started, which creates a negative pressure inside the conical box 8, drawing the material at the bottom of the device body 1 into the filter box 16. The material with residue is filtered by the filter plate 18, and the residue enters the collection box 17. The filtered water returns to the inside of the device body 1 through the guide pipe 6, completing the cleaning of the residue remaining at the bottom of the device body 1.
