A kind of fish pond automatic feeding device, feeding method and oxygen increasing method

Abstract

The invention relates to an automatic fish pond feeding device, a feeding method and an aeration method. The fish pond automatic feeding device includes a support column fixed vertically at the bottom of the pond and a feeding body horizontally rotatably arranged at the top of the support column. The feeding body includes an intermediate material cavity and a particle cavity arranged around the intermediate material cavity; the intermediate material cavity and the particle cavity are separated by a cylindrical outer mesh plate and an inner mesh plate that are nested and attached to each other; The inner mesh plate can be rotated; the upper end of the middle material chamber is provided with a feeding port, and a pressing device for squeezing the fish food to the surroundings is arranged inside; a plurality of outwardly extending feeding arms are uniformly arranged along the outer periphery of the particle chamber; the feeding The arm includes an inner cylinder and a rotatable outer cylinder sleeved at intervals outside the inner cylinder; one end of the inner cylinder communicates with the particle chamber, and a rotatable Jiaolong shaft is arranged in the inner cylinder along its length; A plurality of first particle outlet holes are evenly opened on the cylinder wall; a plurality of second particle outlet holes are evenly opened on the cylinder wall of the outer cylinder.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an automatic feeding device for fish ponds, a feeding method and an oxygenation method. Background technique [0002] A fish pond is a place for fishing or raising fish, especially the inner compartment of a fish enclosure or a purse seine that encloses fish. Generally, an ideal fish pond requires a large area, deep pond water, sufficient light, smooth water source, fertile water quality and convenient transportation, so as to facilitate the growth of fish and the increase of production, and to facilitate production management. In the feeding process, currently Most of them are directly cast by hand, and the fish food mixed into mud is put into the fish pond, which not only has short throwing distance, uneven throwing, poor feeding effect, low utilization rate of fish food, serious waste, and easy fish feeding. Dissolved in the water, causing further waste, in addition, it is also eas...

Generally, an ideal fish pond requires a large area, deep water, sufficient light, unobstructed water source, fertile water quality, and convenient transportation, so as to facilitate the growth of fish, increase the yield, and facilitate production management. During the feeding process, currently Most of them directly use hand throwing, and put the mixed fish food into the fish pond, which not only has a short throwing distance, uneven throwing, poor feeding effect, low utilization rate of fish feed, serious waste, and easy consumption of fish feed. Dissolved in water, resulting in further waste, in addition, it is easy to cause fish schools to hurt each other in the process of grabbing food
