Centralized type automatic feed dispensing and oxygen aeration method for aquaculture

Abstract

The invention relates to a centralized type automatic feed dispensing and oxygen aeration method for aquaculture. The centralized type automatic feed dispensing and oxygen aeration method for aquaculture is characterized by comprising the steps that firstly, a plurality of adjacent ponds in a standard aquaculture pond cluster are correspondingly provided with a large feed dispensing station; secondly, vehicles of a feed supplier directly send feed to the feed dispensing station, and the feed is lifted above a combined bin cluster through a lifting feed loader, and is distributed to all feed distribution bins through an auger distributor; thirdly, each feed distribution bin unloads the feed into an unloading air pipe through a frequency-variable discharger at the bottom; fourthly, each high-pressure draught fan at the bottom divides an air path into a feed scattering air path and an aeration air path through a pneumatic tee joint; finally, the feed scattering air paths annularly spray the feed to the water surface through rotary feed scatters. Aeration pipes located under water in feed scattering regions of the feed scatters enable water in the feed dispensing regions to be aerated, so the requirement for dissolved oxygen for high-intensity feed-intake fish schools in the feed dispensing regions is met.

Description

technical field [0001] The invention relates to a centralized automatic feeding oxygen increasing method for aquaculture, which belongs to the technical field of feed feeding in aquaculture ponds. Background technique [0002] At present, when feeding and increasing oxygen in pond culture, a single pond generally uses feeding machines and aeration machines that work independently. A certain amount of feed needs to be stored in each feeding machine, and the person who transports the feed is responsible for sending the feed to the feed warehouse. The work of transporting the feed from the feed warehouse to the feeding machines by each pond needs to be done manually, and the labor intensity is very high; at the same time, each pond has a separate aerator, which leads to scattered equipment, single function, and cannot be controlled centrally. The cost and use cost are high. [0003] The existing feeding method is to use an independent feeding machine for feeding. At present, t...

AI Technical Summary

Problems solved by technology

[0002] At present, when feeding and increasing oxygen in pond culture, a single pond generally uses feeding machines and aeration machines that work independently. A certain amount of feed needs to be stored in each feeding machine, and the person who transports the feed is responsible for sending the feed to the feed warehouse. The work of transporting the feed from the feed warehouse to the feeding machines by each pond needs to be done manually, and the labor intensity is very high; at the same time, each pond has a separate aerator, which leads to scattered equipment, single function, and cannot be controlled centrally. High cost and usage

[0003] The existing feeding method is to use an independent feeding machine for feeding. At present, the existing feeding machines on the market are mostly fixed on the bank of the pond, and the storage capacity and feeding capacity are generally small, and the feeding area and angle Limited, low degree of intelligence, frequent manual feeding and other shortcomings; at the same time, the feed is not evenly distributed, and the feed utilization rate is not high, resulting in certain pollution to the water in the breeding pond

[0004] In the existing oxygen increasing method, the oxygen increasing machine is floated on the water surface, and the oxygen increasing effect on the middle and lower water body is not obvious, and each oxygen increasing machine is set separately, which is inconvenient to use and control
