Description

Suspension type fish fry releasing device

Technical Field

The utility model relates to a fish breeds the device of releasing, in particular to suspension type fish fry breeds the device of releasing.

Background

The fish breeding and releasing is to put in artificially cultured or bred local parents and fries of fishes in public water areas such as oceans, rivers, lakes, reservoirs and the like so as to achieve the purposes of increasing the biomass of fisheries and protecting the ecological environment of the water areas. The mode of proliferation releasing is various, and traditional fish releasing mode is: the released fry is loaded into a running water vehicle from a nursery site and carried to a released water area, then the fish is fished out from the running water vehicle and loaded into a plastic bucket (pot), and then the fish is poured into the released water area. The main disadvantages of this release method are: consumes a large amount of manpower and material resources, has low working efficiency, and easily causes fish body injury by multiple transfer operations, thereby influencing the survival rate of the fries. In order to improve the releasing efficiency, a slideway device can be adopted for releasing. However, the following disadvantages exist in this type of releasing mode: the slideway device is heavy and inconvenient to transport, disassemble and assemble.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a suspension type fish fry class device of releasing is provided, the device is whole light, and it is convenient to carry the equipment, releases efficiently to can effectively reduce the injury to the fry.

The technical scheme of the utility model as follows:

a suspension type fish fry releasing device is characterized by comprising PVC plastic-coated cloth with small sewing pipes on the left side and the right side, wherein the small sewing pipes are internally provided with telescopic steel pipes, and the small sewing pipes and the telescopic steel pipes are fastened through self-locking nylon ties; the top end of the telescopic steel pipe is connected with a hook; the releasing device also comprises a transition bag positioned above the PVC plastic-coated cloth, the transition bag is a flexible bag with an upper opening end and a lower opening end, and the periphery of the upper opening end is connected with a rigid frame or an elastic frame.

Preferably, each section of the telescopic steel pipe is a square steel pipe.

Preferably, the lower end of the hook is connected with the telescopic steel pipe in a threaded connection mode.

The utility model has the advantages of: a drainage channel is formed by adopting a PVC plastic-coated cloth water-holding mode, fish fries are guided to the drainage channel by virtue of a flexible transition bag, and the fish fries automatically and slowly flow into a drainage water area. Continuous operation is realized in the releasing process, the efficiency is high, and the damage to the fry in the releasing and transferring process is controlled to the minimum degree.

The utility model discloses a two shrink tubes have realized the water and land transition of PVC plastic-coated cloth, are particularly useful for the vehicle can't closely be close to the place of releasing of the surface of water.

The utility model discloses it is whole light still to have the device, carries the convenient outstanding characteristics of equipment.

Fig. 2 is a schematic view of the connection relationship between the hook and the telescopic rod in the embodiment of the present invention.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1, the embodiment of the utility model discloses a PVC plastic-coated cloth 1 that the left and right sides has respectively to make up tubule 2, make up and be provided with retractable steel pipe 3 in the tubule 2, make up and tie up through from locking-type nylon ribbon 4 between tubule 2 and the retractable steel pipe 3. The top end of the uppermost section of the telescopic steel pipe 3 is connected with a hook 5.

In order to make the connection between the small sewing pipe 2 and the telescopic steel pipe 3 more firm, each section of the telescopic steel pipe 3 is designed as a square steel pipe.

In order to facilitate the disassembly and assembly of the hook, the lower end of the hook 5 is in threaded connection with the top end of the uppermost section of the telescopic steel pipe 3, as shown in fig. 2.

The embodiment of the utility model also includes the transition bag 6 shown in fig. 1, and this transition bag 6 is the flexible bag that has two upper and lower open ends, and wherein the periphery of upper port is connected with rigid frame or elastic frame 6-1, and lower port is located PVC plastic-coated cloth 1 top and lower port contacts with PVC plastic-coated cloth 1 when using.

Stretching the telescopic steel pipes 3 to a proper length to ensure that the bottom ends of the telescopic steel pipes 3 are positioned below the water surface of a drainage water area, correspondingly inserting the left and right telescopic steel pipes 3 into the small sewing pipes 2 which are prepared in advance at the left and right sides of the PVC plastic-coated cloth 1, fastening the PVC plastic-coated cloth 1 and the telescopic steel pipes 3 by penetrating the PVC plastic-coated cloth 1 through self-locking nylon ribbons 4, and hanging the upper ends of the hooks 5 at the fish-mouth position or other proper positions of the water-activating vehicle 7. Connecting the inlet end 6-1 of the transition bag 6 to a fish placing opening of a water-activating vehicle 7, opening the fish placing opening, and allowing the released seedlings to flow through the transition bag 6 and flow into water along the PVC plastic-coated cloth 1.
