Automatic feed feeding device for cage type fish culture

Abstract

The invention discloses an automatic feed feeding device for cage type fish culture. The automatic feed feeding device comprises a cage body, a set of slide rail, an automatic feeding bin, a filling device, a horseshoe-shaped toggling ring and a feed bin, and the cage body is provided with a metal frame formed by making longitudinal rods engaged with transverse rods; the slide rail is arranged in the metal frame; the automatic feeding bin is slidably arranged on the set of slide rail, and comprises multiple feeding pipes which are uniformly and parallelly arranged at intervals, and pipe cavities of the feeding pipes are communicated with one another; the filling device is detachably engaged with the feeding opening of the feeding pipe at the uppermost end of the multiple feeding pipes through a feed filling opening; the horseshoe-shaped toggling ring is fixed to the portion below the feed filling opening, and in the vertical direction, an opening of the horseshoe-shaped toggling ring is located over the free end of a cap body; the feed bin is communicated with the other end of a feed filling pipe. The automatic feed feeding device for the cage type fish culture can intensively deliver fish feed into a water body in the cage, fish automatically take the feed instead of being fed, in this way, waste of the feed is drastically reduced, the pollution of the feed to the water body can further be avoided, and the cost of cage fish culture is drastically reduced.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a cage type automatic feed feeding device for fish breeding. Background technique [0002] In the inland areas of our country, the freshwater fish farming methods include: pond fish farming, rice field fish farming, river fish farming, lake fish farming, reservoir fish farming, cage fish farming, seine and fence fish farming and factory fish farming ; Although pond fish farming is still the fish farming method used in most areas of China, the output accounts for more than 60% of freshwater fish farming; however, fish farming in cages has a high degree of intensification, high fish density, and fast growth of fish. The yield is high, and the natural waters can be fully utilized, so its development prospect is huge; however, in the process of cage fish farming, the cages are generally placed in open water or floated on the water, and the fish feed is fed When consuming, a large pa...

The yield is high, and the natural waters can be fully utilized, so its development prospect is huge; however, in the process of cage fish farming, the cages are generally placed in open water or floated on the water, and the fish feed is fed At this time, a large part of the fish feed will be lost with the water body, resulting in a great waste of fish feed, and will cause certain pollution to the water body
