Embodiment Construction

[0028] In conjunction with the accompanying drawings, the present invention includes a water tank 1 and a seedling throwing tube 2. The seedling throwing tube 2 is evenly distributed in the fish pond or set according to the required throwing point. 1 runs through the upper part of all seedling casting cylinders 2 in turn, and water can be injected into all seedling casting cylinders 2 through water tank 1, and the fry can be injected into each seedling casting cylinder 2 with the water flow in water tank 1; the middle and upper part in seedling casting cylinder 2 A horizontal clapboard 3 is fixed, a water inlet 4 is opened on the clapboard 3, a vertical rotating shaft 5 is installed in the center of the seedling casting tube 2, and the upper end of the rotating shaft 5 is rotatably installed on the bottom of the seedling casting tube 2 through a bearing. On the top, the rotating shaft 5 is equipped with a conical plug 6 which is directly below the water inlet 4. The conical plu...

Abstract

The invention relates to a multi-point fry putting device for fish culture. The problems that multi-point fry putting is large in workload, low in efficiency and large in temperature difference change during putting are effectively solved. According to the technical scheme, the seedling dropping device comprises a water tank and seedling dropping barrels, the seedling dropping barrels are distributed in dropping point positions, the water tank sequentially penetrates through the upper portions of all the seedling dropping barrels, switch units are arranged on the side walls of the seedling dropping barrels, the lower ends of the seedling dropping barrels are open, and columnar cavity type containers are arranged below the lower ends of the seedling dropping barrels; when the inside of the fry throwing barrel reaches a set water level, the switch unit is turned on, the fry throwing barrel and the fishpond slowly exchange water until the water temperature is consistent, meanwhile, water is slowly filled in the container until the container is full, the container descends under the action of gravity, the lower end opening of the fry throwing barrel is opened, and fry in the fry throwing barrel swims out of the fry throwing barrel and enters the fishpond; according to the device, multi-point-position throwing operation of the fries can be completed, meanwhile, the fries can adapt to temperature changes in a sufficient time and mild mode, and the survival quality of the fries is improved.

Description

technical field [0001] The invention relates to the field of culture, in particular to a device for feeding fish fry at multiple points in fish culture. Background technique [0002] The stocking of fry is an important task in fish farming. Since the seedlings are young and have poor adaptability, there are many precautions during stocking. The stocking density and the water temperature difference during stocking are two items that cannot be ignored. [0003] When placing fry, it is generally divided into several types and multi-points. Due to the poor swimming ability of fry and limited swimming range, the seedlings placed in a centralized manner cannot be quickly and widely dispersed to all waters, which may cause excessive local density and fish. The utilization rate of pond resources is low, the fry competition is large, the survival rate is low, and the growth rate is slow, so it is only suitable for small-scale breeding; the current multi-point delivery needs to be del...
