Intermittent sedimentation feeding device for aquaculture

Abstract

The invention discloses an intermittent sedimentation feeding device for aquaculture. The device comprises a feed cavity, a floating plate located on the bottom of the feed cavity, a discharging mechanism located below the feed cavity and a feeding box located on the bottom of the discharging mechanism. Compared with the prior art, the intermittent sedimentation feeding device for aquaculture is simple in structure, bait is put through buoyancy and self weight of the device, sedimentation bait is put through cooperation of a first discharging cavity and a second discharging cavity, a buoy provides buoyancy for the second discharging cavity, relative rotation of the discharging cavities is achieved through cooperation of a limiting mechanism to open feed holes, after the weight of feed in the feeding box below reaches the standard, the feed holes are separated, bait putting can be further limited through cooperation of a closed switch structure in the device, and the device is simple instructure and suitable for popularization.

Description

technical field [0001] The invention relates to a fish breeding technology, in particular to an intermittent subsidence feed feeding device for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. [0003] Fish need to eat fish food to grow up. Among the various production inputs of aquaculture, feed input cost is the largest. According to the survey, the feed input cost of general aquaculture products accounts for more than 70% of the total cost of aquaculture. It is artificially throwing fish food into the fish pond for fish to eat, but when manually throwing fish food into the fish pond, it is time-consuming, laborious, long-term throwing of fish food, people's ...

[0003] Fish need to eat fish food to grow up. Among the various production inputs of aquaculture, feed input cost is the largest. According to the survey, the feed input cost of general aquaculture products accounts for more than 70% of the total cost of aquaculture. It is artificially throwing fish food into the fish pond for fish to eat, but when manually throwing fish food into the fish pond, it is time-consuming, laborious, long-term throwing of fish food, people's arms are prone to soreness, and different breeders have different breeding techniques. It is difficult to achieve standardized feeding based on experience alone. As a result, it will adversely affect the growth of fish, thereby reducing the yield per unit area, and too much feed will sink to the bottom of the pond to waste feed and pollute water quality. It is difficult to rely on low-cost labor to compete. Next, it is necessary to increase the level of investment in technology and equipment. The existing bait feeding device has many disadvantages, such as a large amount of bait is not eaten by the fish in the culture cage, and the throwing bait feeding device has low feed utilization efficiency. The sedimentation of the bait on the bottom of the pond will also affect the growth environment of the bottom shellfish, resulting in the eutrophication trend of the bottom environment. The bait put in at one time cannot find out the remaining amount of bait in time, and cannot be cleared to know whether the bait needs to be fed again Therefore, there is an urgent need for a device that can automatically discharge and adjust the amount of bait according to the amount of fish foraging, and can prevent the sedimentation of the feed, so as to overcome the feeding effect that the existing technology has not achieved.
