Embodiment 1

[0019] The system for sorting dead eggs from rainbow trout eggs comprises: a tray support on which a fish egg tray can be placed. There is a cross slide bracket above the tray bracket, and the cross slide bracket is connected to the tray bracket, or the two are made into an integral structure. A cross slide is connected above the support of the cross slide.

Embodiment 2

[0021] In the system for sorting dead eggs from rainbow trout roe described in Example 1, the roe tray is in the shape of a chamfered platform. The bottom of the fish roe tray is dug with a plurality of grooves with a width equal to or slightly smaller than the width of the fish roe. All structural parts of the fish roe tray are in the form of fine grids. The upper edge of the fish roe tray has a certain width (1-5cm), which can facilitate the placement of the fish roe tray on the tray support described in Embodiment 1.

Embodiment 3

[0023] In the system for sorting dead eggs from rainbow trout eggs described in Embodiment 1, there is a slider in the center of the cross slide table that can slide freely along the cross slide table screw in the X and Y directions of the horizontal plane. The free sliding of the slider is controlled by a stepping motor. A slide bar is connected below the slide block. A detection platform is connected below the pull rod of the slide table. A color recognizer is installed in the middle of the lower surface of the detection table, and an egg suction tube is installed on the left and right sides of the X axis. The color recognizer is a hole-like structure. A sensor for identifying colors is placed in the mouth of the funnel, and the neck is a hollow cylinder structure with a diameter equal to that of the fish eggs. The color sensor can detect the color of the light outside the space from the hollow cylinder. The oviductor can suck away the fish roe corresponding to the mouth...

Abstract

The invention discloses a dead roe sorting system for rainbow trout roes and solves the problem that the dead roes are completely sorted manually during incubation of the rainbow trout roes in the prior art. The system comprises a cross-shaped slide bench, a color recognizer, two roe sucking pipes, and a roe pallet. The roe pallet is arranged on a pallet support. A cross-shaped slide bench support is connected to the pallet support and is connected to the cross-shaped slide bench. The color recognizer and the roe sucking pipes are fixed below a sliding piece in the center of the cross-shaped slide bench through a slide bench pull rod. A stepping motor controller controls the sliding piece in the center of the cross-shaped slide to move freely in horizontal X and Y directions through a stepping motor, so that the color recognizer below the sliding piece can recognize whether the detected roe is dead or not. If the detected roe is dead, the roe sucking pipes at the two sides can suck it out, thereby sorting the dead roes from rainbow trout roes. The system has simple structure, is easy to achieve and has high work efficiency.

Description

technical field [0001] The invention belongs to the fish farming industry, belongs to the field of fish farming automation, and relates to a system for sorting dead eggs from rainbow trout eggs. Background technique [0002] Rainbow trout eggs are spherical, with a diameter of 4 to 7 mm. Egg yolk pale yellow, orange, orange or red. The yolk sac is 5-9 mm long and 3-6 mm wide. The number of days from the fertilized egg to the eye stage is about half of the number of days required for hatching. According to the characteristics of the sensitive period of rainbow trout embryo development, it can be divided into six stages: blastodisc formation, cleavage, emergence of embryonic ring and embryonic shield, somite differentiation, early emergence stage and eye development stage. During the breeding process of rainbow trout, the number of days required for eggs from fertilization to hatching varies with water temperature, and it takes 46 days at an average water temperature of 7.5...
