Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a device suitable for feeding water earthworms of Chinese sturgeon and Dabry's sturgeon, and a method of use, which effectively solves the problem of cutting, cutting, and feeding of Chinese sturgeon and Dabry's sturgeon larvae by different workers. The non-uniform and uneven specifications of decomposed water earthworms lead to low feeding efficiency, low fish feeding rate, and unfavorable key technical problems such as larvae cultivation; at the same time, the feeding work of Chinese sturgeon and Dabry's sturgeon in the larvae stage has been automated, standardized, Standardization and quantification make the breeding work more precise and technological, and effectively improve work efficiency

Embodiment 1

[0025] see figure 1 , a kind of device that is suitable for Chinese sturgeon, Dabry's sturgeon mouth feeding water earthworm, it comprises the meat grinder 1 that is used for cutting, decomposing to feed water earthworm, and described meat grinder 1 is equipped with feeding device; The other end of the meat grinder 1 is connected to the collector 4 through a discharge pipe, and the collector 4 is placed and supported on an electronic scale 12 for weighing. The feeding device of water earthworm; described meat grinder 1 and electronic scale 12 are all connected with the control system that is used to control its work. By adopting the device with the above structure, it can be used to cut and decompose the water earthworms fed when feeding the larvae of Chinese sturgeon and Dabry's sturgeon, so as to ensure the uniformity of cutting, improve the feeding efficiency, and ensure the feeding efficiency of the fish. Class feeding effect, thereby ensuring the cultivation of larvae. ...

Embodiment 2

[0033] A method for using a device suitable for feeding water earthworms through the mouth of Chinese sturgeon and Dabry's sturgeon, which comprises the following steps:

[0034] Step1: When in use, open the feed inlet valve 5, close the discharge outlet valve 6, put the water worms into the feed inlet funnel 3, after the water earthworms enter the meat grinder 1, close the feed inlet valve 5;

[0035] Step2: According to the specification requirements of feeding water earthworms, set and control the number of starts and stops of the meat grinder 1 and the parameters of the running time of each start through the controller 2;

[0036] Step3: Start the meat grinder 1, cut and decompose the water earthworms through the meat grinder 1, after the water earthworms are cut into suitable specifications, open the discharge valve 6, and the cut water earthworms enter the collector 4 by gravity ;

[0037] Step4: Use the electronic scale 12 to weigh the water worms inside the collector ...

Abstract

The invention provides a device suitable for opening Chinese sturgeons and acipenser dabryanus to feed tubificidae and a using method. The device comprises a meat grinder used for cutting and decomposing the to-be-fed tubificidae, wherein a supplying device is installed on the meat grinder; the other end of the meat grinder is connected with a collector through a discharging pipe, the collector is placed and supported on an electronic scale used for weighing, and a feeding device used for feeding the chopped tubificidae is installed inside the collector; and the meat grinder and the electronic scale are connected with a control system for controlling the meat grinder and the electronic scale to work. The key technical problems that when different workers feed Chinese sturgeon and acipenser dabryanus fries, the specifications of the cut and decomposed tubificidae are not uniform, so that the feeding efficiency is low, the fish feeding rate is low, and the fries are not beneficial to cultivation are effectively solved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a device and a method for feeding water earthworms through the mouth of Chinese sturgeon and Dabry's sturgeon. Background technique [0002] Both Chinese sturgeon and Dabry's sturgeon are national first-level key protected aquatic wild animals. In recent years, affected by various human factors, the amount of natural resources has declined year by year. Carrying out artificial breeding, seed cultivation, multiplication and release of Chinese sturgeon and Dabry's sturgeon is particularly important for the restoration of natural resources. The opening of the larvae of Chinese sturgeon and Dabry's sturgeon is an important link in the survival and growth of fish under artificial breeding conditions. In the large-scale cultivation work, choosing water earthworms to carry out opening cultivation is a method with the best effect among the existing methods of opening, but in the la...
