Technical Field

The invention relates to the technical field of shrimp catching devices, in particular to an automatic crayfish catching device.

Background

The crayfish catching cage is generally used for catching crayfish, but the existing crayfish catching cage needs to consume a large amount of manpower, particularly the time consumed for collecting the crayfish is long, and due to the fact that freshness and liveness need to be guaranteed when the crayfish is supplied to the market, personnel need to be added when the crayfish is harvested, the crayfish is often collected at 4-5 points in the morning, the labor intensity of workers is high, and the manpower cost is high.

After the existing shrimp catching cage is placed in a water body for a period of time, attachments such as moss are easy to grow on the cage net, the shrimp catching effect is greatly reduced, the shrimp catching cage needs to be frequently folded and placed on a pond ridge to be aired, the operation of airing the net is frequent, and a large amount of manpower is consumed. The traditional crayfish cage catching mode has the disadvantages of being relatively hard for operators, high in labor cost and low in efficiency. And no automatic crayfish catching machine or device is reported at present.

Disclosure of Invention

The invention aims to provide automatic crayfish catching equipment, which replaces the catching mode of the existing manual collecting and releasing cage, overcomes the defects of high labor cost and low efficiency, integrates automatic catching and collecting of a crayfish cage, can automatically realize the work of lifting the crayfish cage in the morning to harvest crayfish, then drying the crayfish cage out of water and catching the crayfish by lowering the crayfish cage into water through simple manual operation, and is simple and quick to operate and high in working efficiency.

In order to achieve the purpose, the invention provides the following technical scheme: an automatic crayfish catching device comprises a crayfish catching cage, a crayfish collecting device, a crayfish cage fixing rod device, a movable pulley on the crayfish cage, a fixed pulley on the fixing rod, a twisted rope fixing pile and a crayfish cage lifting device, the shrimp catching cage is a cage body formed by sewing a rectangular stainless steel frame and a fishing net, a movable pulley is arranged above the cage body, the four side surfaces of the cage body are respectively provided with two crayfish crawling inlets, a collecting port is arranged below the shrimp catching cage body and is connected with a shrimp collector, the fixing rods of the shrimp cage are four stainless steel fixing rods and a square frame which are welded into a whole, two fixed pulleys are arranged above the fixing rods, the shrimp cage lifting device is characterized in that the stranded rope is connected with the movable pulley above the cage body and the fixed pulley above the fixed rod, the shrimp cage lifting device is used for lifting the shrimp cage by winding and unwinding the stranded rope through the winch, and the stranded rope fixing piles are arranged at two ends of a group of shrimp cages.

Furthermore, the shrimp cage lifting devices are connected in series through stranded ropes, and the lifting of the 5-20 shrimp catching cages is controlled simultaneously.

Furthermore, the mesh size of the fishing net of the shrimp catching cage has 2 specifications and is respectively used for catching young shrimps and adult shrimps of crayfish.

Furthermore, a movable pulley is arranged above the cage body, and the cage body can be lifted by winding and unwinding the twisted rope.

Further, the crawling inlet of four sides of the cage body is a cylindrical structure sewn by a fishing net, the external inlet is oval and large in diameter, the internal inlet is oblate and small in diameter, and the crawling inlet is suspended and fixed on the cage body frame through a nylon wire system.

Furthermore, the length, the width and the height of the shrimp catching cage body are 1.0m, 1.0m and 0.5 m.

Furthermore, the bottom of the fixing rod is inserted into the bottom mud, so that the fixing rod does not shift when the shrimp catching cage is lifted.

Furthermore, the 5-20 shrimp catching cages are distributed at intervals of 25000 mm.

Compared with the prior art, the invention has the beneficial effects that:

(1) the automatic crayfish catching device has the advantages that the movable pulley is driven by the winch, so that the crayfish catching and collecting work can be completed quickly, the labor cost is reduced, the crayfish collecting time is shortened, and the survival rate of crayfish catching is improved; the crayfish cage can be used for catching crayfish conveniently and quickly in a labor-saving, time-saving and convenient manner according to the market requirement of crayfish, so that the labor is saved, and the flexibility of the crayfish coming into the market is greatly improved.

(2) The automatic crayfish catching device can lift the crayfish catching cage out of water in time to dry the net, is beneficial to maintaining the cleanliness of the crayfish catching cage, and improves the crayfish catching effect; the crayfish capturing efficiency is high, the labor cost is low, and the requirements of large-scale crayfish breeding production can be met.

Detailed Description

The invention will now be further described by way of the following examples, which are not intended to limit the scope of the invention in any way. It will be understood by those skilled in the art that the equivalent substitutions and modifications made in the present disclosure are within the scope of the present invention.

As shown in figure 1, the automatic crayfish catching device comprises a crayfish catching cage, a crayfish collecting device, a crayfish cage fixing rod device, a movable pulley on the crayfish cage, a fixed pulley on the fixing rod, a twisted rope fixing pile and a crayfish cage lifting device. The shrimp catching cage is a cage body formed by sewing a rectangular stainless steel frame and a fishing net, the length, the width and the height of the shrimp catching cage are 1.0m, 1.0m and 0.5m, the mesh size of the cage body for catching the juvenile shrimps is 0.9cm, and the mesh size of the cage body for catching the adult shrimps is 1.5 cm; a movable pulley is arranged above the shrimp catching cage body, and the diameter of the movable pulley is 5 cm; the four side surfaces of the shrimp catching cage body are respectively provided with two crayfish crawling inlets, the outer inlet is oval and has a large diameter, and the inner inlet is oblate and has a small diameter; a collecting port is arranged below the shrimp catching cage body and is connected with a shrimp collector; the fixing rods of the shrimp cage are fixing rod devices formed by welding four stainless steel fixing rods and a square frame into a whole, the fixing rods are provided with two fixed pulleys through the upper part, a movable pulley above the cage body and the fixed pulleys above the fixing rods are connected through a twisted rope, and the twisted rope is wound and unwound to lift the shrimp catching cage through a switch winch.

During installation, the fixing rods of the shrimp catching cages are fixed by inserting bottom mud, 20 shrimp catching cages need to be installed on the same straight line, and the 1 winch controls the lifting of the 20 shrimp catching cages at the same time. When the shrimp catching cage is used, baits can be placed in the shrimp catching cage, then the cage body is descended to the water bottom, the winch is opened after the shrimp catching cage is caught for 8-12 hours, the shrimp catching cage body is lifted to leave the water surface, and the shrimps are collected by manually supporting a boat. After the shrimp collecting work is finished, the cage body can be hung in the air for airing, and the cage body is descended to catch the crayfishes.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
