Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-2 shown.

[0020] A kind of fry opening bait collecting device, it comprises net cage 1, net cage positioning frame 2, water pump 3, bait collecting net tube 4 and bait collecting net bag 5, as figure 1 Shown, net cage 1 is placed in water, is cuboid groove structure, and its upper edge is higher than water surface, and its effect is to allow the bait to be collected to enter while impurity can be blocked, and impurity in water is not allowed to enter net; 1 aperture is generally around 80 mesh. Net cage positioning frame 2 is used to make net cage 1 be fixed in water and can not deform, and this net cage positioning frame 2 links to each other with fixed support 6 by fixing cable; The main purpose is to make the positioning of the net cage positioning frame 2, and the net cage positioning frame 2 is composed of a square fra...

Abstract

The invention provides a fry initial feed collecting device. The device is characterized by comprising a net cage (1), a net cage locating frame (2) and a water pump (3), wherein the net cage (1) is put in water and has a cuboid groove structure; the upper edges of the net cage are higher than the water surface; the net cage has the functions of keeping off impurities and preventing the impurities in water from entering into the net while allowing the feeds to be collected to enter; the net cage locating frame (2) is used for ensuring the net cage (1) to be fixed in water, without deformation; the net cage locating frame (2) is connected with a fixing support (6) by fixing wires; the water inlet of the water pump (3) is connected with one end of a feed collecting net drum (4); the other end of the feed collecting net drum (4) is connected with a hole in the net cage (1); the water outlet end of the water pump (3) is sleeved with a feed collecting net bag (5); and the apertures of the meshes of the feed collecting net drum are smaller than the sizes of the collected feeds. The device has a simple structure and is convenient to manufacture, install and use.

Description

technical field [0001] The present invention relates to a kind of fishery equipment, especially a kind of equipment used in the process of fish breeding, in particular to a kind of bait collection device for fry opening. Background technique [0002] As we all know, fish fry must be fed with rotifers, cladocerans, cylopods and algae to open their mouths in the early stage of reproduction. However, the commonly used method of collecting such baits is to use small-aperture net bags for manual fishing. This method is not only efficient Low, labor-intensive, and there is a danger of falling into the water, it cannot meet the needs of large-scale fry breeding, and has restricted the expansion of fry breeding scale in my country for a long time. Must be improved. Contents of the invention [0003] The purpose of the present invention is to design a kind of fish fry opening bait collection device that can automatically and quickly collect a large amount of bait for the proble...
