Description

Technical Field

[0001] This invention belongs to the field of aquaculture, specifically relating to a method for supervising the feeding of giant freshwater prawns. Background Technology

[0002] Giant freshwater prawns (Macrobrachium rosenbergii) are prized for their delicious meat, rich protein, high nutritional value, broad market prospects, and relatively low farming difficulty, leading to a large-scale aquaculture industry in my country. Large-sized giant freshwater prawns are raised in greenhouses before being released into ponds at suitable water temperatures. This extended growth cycle, combined with the growth advantages of new varieties, increases the prawn size. Currently, large-sized giant freshwater prawns typically weigh around 100-150 grams each, commanding a considerable market price. However, traditional giant freshwater prawn farming methods require frequent manual monitoring of pond feeding and adjustments to feed amounts based on the prawns' feeding behavior, which is time-consuming and labor-intensive. Summary of the Invention

[0003] To achieve the above objectives, the technical solution of the present invention is as follows:

[0004] A feeding monitoring system for giant freshwater prawn cultivation includes: an adjustable feed dispensing device (100) and a networked automatic feed checking station (200).

The networked automatic material checking station (200) includes: a lifting mechanism (21), a material platform (22), a weighing mechanism (23), a shooting mechanism (24), a network module, and a water quality testing net bag (25).

[0010] Preferably, the metering conveyor (112) is located at the bottom outlet of the storage tank (111), and the metering conveyor (112) includes a metering pump and a screw conveyor.

[0011] Preferably, the material distribution pipe (113) includes a main pipe and a branch pipe. The main pipe is connected to the quantitative conveyor (112), and the branch pipes are respectively connected to the material distribution box (114). An electric control valve (1131) is provided on the branch pipe.

[0012] Preferably, a feed control valve is provided at the feed inlet (122).

[0013] Preferably, the feeding disc (133) includes: a hollow feeding disc (1331), a feeding vane (1332), and a rotary motor (1333). The hollow feeding disc (1331) has a feeding port (1334) on its side. The feeding vane (1332) is disposed inside the hollow feeding disc (1331), and its bottom is connected to the rotary motor (1333). The hose connector (132) is connected to the hollow feeding disc (1331). Feed falling into the hollow feeding disc is flung out of the feeding port by the impact of the feeding vane.

[0015] Preferably, the weighing mechanism (23) includes two tension gauges, which are respectively disposed between the material platform pull rope (212) and the material platform (22) and between the net bag pull rope (214) and the water quality detection net bag (25).

[0018] A method for monitoring feeding of giant freshwater prawns, using the aforementioned feeding monitoring system, includes the following steps:

[0019] S1. Feed metering: Pour the feed into the storage bin (111), and send the metered feed into each distribution bin (114) through the metering conveyor (112);

[0020] S2, Feed conveying and sprinkling: Each feed box (114) corresponds to a different suspension sprinkling mechanism (13), which blows the feed in the feed box (114) to the sprinkling plate (133) for sprinkling and feeding through its corresponding air conveying mechanism (12);

[0021] S3, Feeding on the feeding platform: When feeding, lift up the feeding platform (22) and feed the platform (22) through the feeding tray (133). The feeding platform (22) contains 1% to 2% of the feed amount for each feeding.

[0022] S4. Feed control: At each suspension sprinkling mechanism and networked automatic feed monitoring station, the feed station (22) is lifted by the lifting mechanism (21) at regular intervals to monitor the remaining feed and calculate the next feeding amount. The monitoring method is as follows: after lifting the feed station (22) and waiting for the feed station (22) to stabilize, the change rate of the pull gauge is recorded to determine whether the feed needs to be increased. ① If the drainage speed is close to the drainage speed of the empty net of the feed station, it is determined that there is no feed left and feed needs to be added. ② If the drainage speed is slower than the drainage speed of the empty net, it means that feed does not need to be added. ③ If the drainage speed is particularly slow or there is no drainage speed, it means that the next feeding needs to be reduced. ④ At the same time, the photo is recorded by the shooting mechanism (24) and uploaded to the monitoring room so that the management personnel can help judge the feeding situation.

[0023] S5. Water quality monitoring and investigation: While pulling up the feed platform (22), pull up the water quality testing net bag (25). According to the change rate of the recorded tension gauge count, compare it with the drainage rate of the clean water quality testing net bag (25). If the drainage rate is close, it means that the water quality is good. If the drainage rate is significantly slower, it means that a large number of impurities are attached to the water quality testing net bag (25). Then, an alarm is sent to the monitoring room to remind the water quality to be improved, cancel the feed residue judgment result of this time, open the manual feed inspection platform, and send people to clean the feed platform (22) and the water quality testing net bag (25) at the same time to prevent subsequent mistesting.

[0024] In summary, the beneficial effects of this invention are as follows:

[0025] 1. The feeding monitoring system for giant freshwater prawn cultivation described in this invention automatically checks the feed consumption status through a networked automatic feeding platform and feeds the results back to an adjustable feed spreading device, thereby controlling the amount of feed fed at different locations in the prawn pond, which greatly saves manpower.

[0026] 2. The feeding and monitoring method for giant freshwater prawns described in this invention can reduce misjudgments at the feeding platform monitoring point by setting up a water quality detection net bag, and at the same time can alert to changes in water quality.
