[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , this embodiment discloses a feed conveying system, which includes a material transportation cabin 100, an air-material separator 200, a transition tank 300, a feeder 400, and a blower 500. The material transportation cabin 100 is provided with a discharge port 110, and the discharge port 110 is connected to a discharge pipe 130. The first end of the discharge pipe 130 is connected to an intake pipe 140. The air-material separator 200 is provided with a feed inlet 210, a separation port 220, and an air outlet 230. The feed inlet 210 is connected to the second end of the discharge pipe 130, and the air outlet 230 is connected to an extraction pipe 240. The transition tank 300 is installed below the separation port 220. The feeder 400 is installed at the bottom of the transition tank 300, and the feeder 400 is connected to a conveying pipe 420. The first side of the blower 500 is connected to the extraction pipe 240 and is connected to the air outlet 230 through the extraction pipe 240. The second side of the blower 500 is connected to a supply pipe 250 and is connected to the feeder 400 through the supply pipe 250. The supply pipe 250 is communicated with the conveying pipe 420. When the material transportation cabin 100 is opened, after the feed in the material transportation cabin 100 falls into the discharge pipe 130, the negative-pressure air generated by the blower 500 sucks the feed into the air-material separator 200. The feed falls to the bottom of the air-material separator 200 under the action of gravity, enters the transition tank 300 for temporary storage, and is scattered into the feeder 400 according to requirements. When the feeder 400 is opened, the positive-pressure air discharged by the blower 500 blows the feed in the feeder 400 along the conveying pipe 420 to the target position. By adopting a conveying method that combines negative-pressure suction of feed and positive-pressure blowing of feed, the conveying distance is farther, and the problem of high energy consumption caused by a single positive-pressure conveying method is solved; the excessive wind pressure is avoided, and the breakage rate of the feed is effectively reduced, thereby improving the feeding effect of fish and the utilization rate of the feed.

[0030] The material conveying bin 100 is used as a feed storage tank, and the feed to be delivered is stored in the material conveying bin 100. In the related art, the gas conveying power device is generally arranged at the first end of the discharge pipe 130 (such as the connection end between the discharge pipe 130 and the intake pipe 140), so as to send the feed falling into the discharge pipe 130 along the discharge pipe 130 through positive pressure wind and directly discharge it from the conveying pipe 420. In this embodiment, by optimizing the pressure distribution, for example, arranging the blower 500 at the second end of the discharge pipe, and arranging the air - material separator 200, the transition tank 300 and the feeder 400 between the blower 500 and the discharge pipe 130, air - material separation during the feed transportation process is achieved to complete the negative pressure conveying for the first - stage distance and provide buffering for the second - stage distance, so that the feed can start positive pressure conveying at a new starting point (the position corresponding to the feeder 400). In this way, through the combination of negative pressure conveying for the first - stage distance and positive pressure conveying for the second - stage distance, long - distance feed conveying can be realized. It can make full use of the negative pressure generated during the operation of the fan to suck in the feed, avoiding the situation where an extremely high wind pressure is required to overcome the high resistance brought by long - distance conveying in a single positive pressure conveying method. That is to say, the traditional positive pressure conveying method requires a powerful fan to generate a high wind pressure, especially when the conveying distance is long. In this embodiment, since the wind pressure is distributed in two stages, the burden on a single blower 500 is reduced, so the required power is lower, thereby reducing the energy consumption of the conveying system.

[0031] It should be noted that the air supply pipe 250 can be indirectly or directly connected to the conveying pipe 420. If the feeder 400 is connected with a buffer pipe or provided with a buffer cavity, the feed falls from the feed port 410 of the feeder 400 into the buffer pipe or the buffer cavity. At this time, the air supply pipe 250 and the conveying pipe 420 are respectively connected to both ends of the buffer pipe or the buffer cavity, and the air supply pipe 250 and the conveying pipe 420 are indirectly connected. If the feeder 400 is not connected with a buffer pipe or provided with a buffer cavity, the feed directly falls from the feed port 410 of the feeder 400 into the air supply pipe 250 or the conveying pipe 420. At this time, the air supply pipe 250 and the conveying pipe 420 are directly connected.

[0032] Please refer to Figure 2 , the blower 500 is provided with a suction port 510 and a discharge port 520. The suction port 510 is the negative pressure end and is connected to the air - material separator 200, and the discharge port 520 is the positive pressure end and is connected to the feeder 400. The negative pressure air generated by the blower 500 at the suction port 510 sucks the feed into the air - material separator 200; the positive pressure air generated by the blower 500 at the discharge port 520 blows the feed of the feeder 400 along the conveying pipe 420 to the target position.

[0033] Please refer to Figure 2, a first pressure sensor 511 is provided at the negative pressure end of the blower 500, and a second pressure sensor 521 is provided at the positive pressure end of the blower 500. It should be noted that the first pressure sensor 511 is located at the negative pressure end of the blower 500, and its reading is a negative pressure value, which matches the negative pressure during the suction and delivery process of the blower, ensuring that the negative pressure can effectively suck the material into the discharge pipe 130; the second pressure sensor 521 is located at the positive pressure end of the blower 500, and its reading is a positive pressure value, reflecting the thrust provided by the blower during operation, which specifically depends on the capacity of the blower.

[0034] Please refer to Figure 2 , the blower 500 is a magnetic levitation blower. The magnetic levitation blower adopts a magnetic levitation bearing system, eliminating the complex gearbox and oil-based bearing system necessary for traditional blowers, achieving lubricant-free and mechanical maintenance-free operation, effectively reducing maintenance costs, and ensuring the stability, low noise, high efficiency, and energy conservation of the blower system.

[0035] Please refer to Figure 2 , the suction pipe 240 is connected to an air filter 600, and the air filter 600 is provided with multiple layers of filter meshes. The separated feed falls to the bottom of the air-solid separator 200 under the action of gravity. The air enters the suction pipe 240 from the air outlet 230. The air filter 600 removes the dust in the negative pressure air through multiple layers of filter meshes or filter materials, preventing the mixture of dust and air from entering the blower 500 and blocking the operation of the blower 500.

[0036] Please refer to Figure 2 , a first throttle valve 241 is provided between the air filter 600 and the blower 500. After starting the blower 500, open the first throttle valve 241 to supplement air, adjust the air flow rate, and maintain the stability of the air pressure.

[0037] Please refer to Figure 2 , the air outlet 230 is provided above the feed inlet 210. After the negative pressure air sucks the feed into the air-solid separator 200, the feed falls to the bottom of the air-solid separator 200 under the action of gravity and enters the transition tank 300 for temporary storage. The separated negative pressure air is sucked into the air filter 600 via the air outlet 230 and the suction pipe 240, and the air filter 600 filters out impurities such as dust therein.

[0038] Please refer to Figure 3, a discharge valve 120 is installed at the discharge port 110, and the discharge valve 120 is a slide valve. The slide valve has the advantages of compact structure, reliable sealing, lightness, flexibility, smooth channel, and small flow resistance. When the discharge valve 120 is opened, the feed falls from the discharge port 110 into the discharge pipe 130, and the negative-pressure air generated by the blower 500 at the suction port 510 sucks the feed into the air-feed separator 200. The feed falls to the bottom of the air-feed separator 200 under the action of gravity and enters the transition tank 300 for temporary storage, and can be scattered into the feeder 400 according to needs.

[0039] Please refer to Figure 3 , a second throttle valve 141 is installed on the air inlet pipe 140. When the second throttle valve 141 is opened, air fully enters the air inlet pipe 140, facilitating the negative-pressure suction of the feed.

[0040] This embodiment also discloses a breeding workboat, including the above-mentioned feed conveying system.

[0041] Please refer to Figure 4 , the material transportation cabin 100 is arranged below the main deck 710 of the breeding workboat, and the air-feed separator 200, the transition tank 300, the feeder 400, and the blower 500 are installed on the poop deck 720 of the breeding workboat. It should be noted that the arrow direction in the pipeline is the air flow direction. When the feed needs to be transported, the second throttle valve 141 is opened, and air fully enters the air inlet pipe 140; the blower 500 is started, and the first throttle valve 241 is opened for air supplement; after the pressure at the first pressure sensor 511 is normal, the discharge valve 120 is opened, and the feed falls into the discharge pipe 130. The negative-pressure air generated by the blower 500 at the suction port 510 sucks the feed into the air-feed separator 200. The feed falls to the bottom of the air-feed separator 200 under the action of gravity and enters the transition tank 300 for temporary storage, and can be scattered into the feeder 400 according to needs; the separated negative-pressure air is sucked into the air filter 600 through the suction pipe 240, and the air filter 600 filters out impurities such as dust; when the pressure value at the second pressure sensor 521 reaches the preset value, the feeder 400 is opened, and the positive-pressure air generated by the blower 500 at the discharge port 520 blows the feed in the feeder 400 along the conveying pipe 420 to the target position, such as the feed inlet pipe of the feed spreading device. By adopting a conveying method combining negative-pressure suction of the feed and positive-pressure blowing of the feed, the conveying distance is farther, and the problem of high energy consumption caused by a single positive-pressure conveying method is solved; it avoids excessive wind pressure when the air volume demand is large, effectively reduces the breakage rate of the feed, thereby improving the feeding effect of fish and the utilization rate of the feed; the material transportation cabin 100 can be arranged below the main deck 710 of the breeding workboat, and the air-feed separator 200, the transition tank 300, the feeder 400, and the blower 500 are installed on the poop deck 720 of the breeding workboat, with a compact structure, flexible layout, and space saving.
