Description

A simple cone snail trapping device

technical field

The utility model belongs to the technical field of trapping devices for marine organisms, and relates to a simple trapping device for conical snails.

Background technique

Conic snails are a kind of Mesogastropods and Conic Snails. The shell is slender and delicate, with about 30 layers of convex spiral layers, arranged in order from small to large. The screw shaft and shell mouth are both round. A popular economic snail. Cone snails are widely distributed in natural sea areas, and there is no breeding at present. There is no special harvesting method for cone snails. Most of them are picked up artificially or harvested by-products of other shellfish. Therefore it is necessary to design a trapping device for trapping the physiological characteristics of the cone snail.

Contents of the invention

The purpose of the utility model is to provide a simple cone snail trapping device which can conveniently trap the cone snails for the above-mentioned problems existing in the prior art.

The purpose of this utility model can be achieved through the following technical proposals: a simple cone snail trapping device is characterized in that: it includes an upper iron frame and a lower iron frame that are all rectangular frame structures, and the upper iron frame and the lower iron frame respectively include four An upper frame pole and a lower frame pole enclosed by each other, the plane where the upper iron frame is located is parallel to the plane where the lower iron frame is located, the vertical projection of the upper iron frame is located in the lower iron frame, and the four corners of the upper iron frame and the four corners of the lower iron frame pass through The iron rods are connected, and the upper iron frame, the lower iron frame and the four iron rods are surrounded to form a pyramid-shaped net frame with an upper opening. The net frame is covered with fishing nets around and at the bottom. The hook includes a rod-shaped hook rod whose rear end is vertically fixed to the upper rack rod. The plane where the upper iron frame is located is set at an acute angle with the hook rod. The point is located below the hook bar, and the hook point is projected vertically on the hook bar. The four corners of the upper iron frame are also fixed with binding ropes.

At the opening position above the net frame, use the tip of the hook to fix small miscellaneous fish to trap creatures. The four corners of the upper iron frame are tied with ropes, and the length can be adjusted. Cone snails will climb onto the trapping device to feed on small miscellaneous fish, and then slide down along the hook rod into the net frame. Because the shell of the cone snail is relatively slender, it cannot climb out of the net frame after sliding, and the net frame is used Wrapped in fishing nets, the water permeability is good, and the snails can survive in the net frame, so the snails caught are all living.

In the above-mentioned simple cone snail trapping device, it also includes four guide nets with trapezoidal net plate structure, and the four guide nets are respectively fixed around the net frame, and the fishing nets around are attached to the outside of the guide net.

Therefore, it is convenient for the cone screw to climb into the net frame along the guide net, and the cone screw in the net frame is blocked by the hook rod.

In the above-mentioned simple cone snail trapping device, the rear ends of the hook rods corresponding to the plurality of bait hooks are jointly connected to a clamp, and the clamp is detachably clamped on the upper rack rod.

Therefore, it is convenient to fix small miscellaneous fish on the hook tip.

In the above-mentioned simple cone snail trapping device, the upper iron frame is a square structure of 13cm*13cm, the lower iron frame is a square structure of 26cm*26cm, and the distance between the upper iron frame and the lower iron frame is 3.5cm , the mesh of the fishing net is 15 mesh.

Compared with the prior art, the utility model has the following advantages:

At the opening position above the net frame, use the tip of the hook to fix small miscellaneous fish to trap creatures. The four corners of the upper iron frame are tied with ropes, and the length can be adjusted. Cone snails will climb onto the trapping device to feed on small miscellaneous fish, and then slide down along the hook rod into the net frame. Because the shell of the cone snail is relatively slender, it cannot climb out of the net frame after sliding, and the net frame is used Wrapped in fishing nets, the water permeability is good, and the snails can survive in the net frame, so the snails caught are all living.

Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Fig. 1, a kind of simple and easy conical snail trapping device of the present utility model comprises the upper iron frame 1 and the lower iron frame 2 that are all rectangular frame structures, and the upper iron frame 1 and the lower iron frame 2 respectively comprise four mutually enclosing The upper pole and the lower pole, the plane where the upper iron frame 1 is located is parallel to the plane where the lower iron frame 2 is located, the vertical projection of the upper iron frame 1 is located in the lower iron frame 2, the four corners of the upper iron frame 1 and the four corners of the lower iron frame 2 The positions are connected by iron rods 3, and the upper iron frame 1, the lower iron frame 2 and the four iron rods 3 are enclosed to form a pyramid-shaped net frame with an upper opening. Some rod-shaped bait hooks 5, the bait hook 5 comprises the rod-shaped hook bar 51 that the rear end is vertically fixed with the upper rack bar, the plane where the upper iron frame 1 is located is set at an acute angle with the hook bar 51, and the vertical projection of the hook bar 51 is located on the upper iron bar. In the frame 1, the front end of the hook bar 51 is bent to form a hook point 52, and the hook point 52 is located below the hook bar 51, and the hook point 52 is vertically projected on the hook bar 51, and the four corners of the upper iron frame 1 are also fixed with a binding rope 6 .

Further, it also includes four guide nets 7 with trapezoidal mesh structure, and the four guide nets 7 are respectively fixed around the net frame, and the surrounding fishing nets 4 are attached to the outside of the guide nets 7 . The rear ends of the corresponding hook bars 51 of several bait hooks 5 are jointly connected on a clip, and the clip is detachably stuck on the upper rack rod. The upper iron frame 1 is a square structure of 13cm*13cm, the lower iron frame 2 is a square structure of 26cm*26cm, the distance between the upper iron frame 1 and the lower iron frame 2 is 3.5cm, and the 4 meshes of the fishing net are 15 orders.

Utilize the hook tip 52 to fix the small miscellaneous fish at the opening position above the net frame to trap creatures, and the four jiaos of the upper iron frame are bound with the binding rope 6, and the length can be adjusted. The cone snail can climb onto the trapping device to eat small miscellaneous fish, and then slides down into the net frame along the hook bar 51. Because the shell of the cone snail is relatively slender, it can no longer climb out of the net frame after sliding, and the net frame is Wrapped with fishing net 4, the water permeability is better, and the cone snails can survive in the net frame, so the cone snails trapped are all living bodies.
