Description

Trap for catching large birds without damage

Technical Field

The invention belongs to the field of bird capture, and particularly relates to a trap for capturing large birds without injury.

Background

In the migration research of large birds such as cranes, geraniums and the like, the method for performing the cyclization is one of the most effective methods. It is known that an essential step of bird survival is the safe capture of birds.

At present, three methods are mainly adopted abroad to capture the heroubill birds: the first is to adopt helicopter blocking, which is not only high in cost and inconvenient, but also easy to cause injury to birds; the second is to mix the narcotic with the food, which not only needs a certain technical condition, but also is easy to cause injury to birds once the operation is improper; the third method is a net throwing method, which is effective, but the use of a plurality of gunpowder is limited, and the popularization is difficult.

Particularly, when the bird is caught by the throwing net, the bird struggles vigorously in the net, so that feathers of the bird can be damaged, the bird can die seriously, and how to cause the bird not to be damaged in the bird catching process becomes a problem to be solved urgently.

Disclosure of Invention

In order to solve the problems, the invention aims to provide a trap for trapping large birds without damage so as to solve the defect that birds struggle in nets to cause bird damage in the process of trapping large birds.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a do not have to hinder trap of catching large-scale birds includes the stay cord and lays the horizontal pole on ground, the lower surface and the ground of horizontal pole are connected with the fastener, the upper surface of horizontal pole is connected with a plurality of iron cores, the iron core includes free end and stiff end, the stiff end and the horizontal pole fixed connection of iron core, the free end of iron core is equipped with first ring, the stay cord is on the surface of iron core, the stay cord is connected with the second ring, wherein the one end that the second ring was kept away from to the stay cord embolias in the first ring, second ring department passes the iron core is connected to the stay cord, wherein the second ring pastes the stiff end that leans on in the iron core, and the second ring slides on the surface of iron core, when the stay cord level in the horizontal pole, the iron core forms bow-shaped, bow-shaped iron core divides into a plurality of shares with the horizontal pole equidistant.

Further, the bow shape comprises a bow body and a bow string, the bow body is an arched iron core, the bow string is a horizontal pull rope, an accommodating space is formed between the bow body and the bow string, and when the shape of the bow body changes, the bow string slides along the bow body, so that the size of the accommodating space is changed.

After the scheme is adopted, the following beneficial effects are realized: when birds passed through, accommodation space was stepped into to the foot of birds, and birds when stepping on forward, birds gave the external force of applying of iron core, thereby make second ring rebound, when the elasticity sum of the forward stepping force of birds and iron core was greater than the frictional force of second ring and iron core, the stay cord slided along the iron core, thereby the iron core is turned into vertically by the bow-shaped, accommodation space dwindles this moment, consequently, the stay cord twines the step of birds, and form the slipknot fast, the removal of restriction birds, realize the nothing of large-scale birds and hinder the seizure.

The initial kinetic energy of the bird passing through changes the direction of movement of the pull cord to wind the pull cord around the legs of the bird.

Furthermore, the fastener comprises an outer screw and an inner screw which are nested with each other, the outer screw is hollow, an internal thread is machined in the outer screw, the internal thread is in threaded connection with the inner screw, and a vertical through groove is formed in the outer part of the outer screw;

the inner screw comprises a bolt head and a bolt tail which are integrally manufactured, wherein a plurality of mutually independent metal folding pieces are connected between the bolt head and the bolt tail, gaps are arranged among the metal folding pieces, and each metal folding piece corresponds to the through groove one by one.

Has the advantages that: this technical scheme utilizes the fastener to fix horizontal pole and ground, thereby realize the stability of horizontal pole, fall this device area when avoiding birds to step on, consequently during fixed horizontal pole, squeeze into ground with outer screw earlier, screw in the outside screw of interior screw afterwards, conflict to outer screw's the bottommost back at the in-process bolt tail of screwing, the interior screw of continuously screwing again, interior screw atress back metal folded piece produces and buckles this moment, the metal folded piece extends logical groove this moment, the coverage of fastener has been expanded in the diversion, thereby realize stabilizing.

Further, the bolt head is provided with a cross screw groove.

Further, the fastener includes a vertical fastening bolt.

Furthermore, the pull rope is woven by two strands of ropes which are mutually intertwined, and the ropes are wound on the surface of the second circular ring.

Has the advantages that: reduce the injury of the ring to the birds foot, produce the protective force when colliding.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the pull rope comprises a pull rope 1, a cross rod 2, a fastening bolt 3, an iron core 4, a first circular ring 5, a second circular ring 6, an accommodating space 7, an outer screw 8, an inner screw 9, a through groove 10 and a metal folding piece 11.

Example one

The embodiment is basically as shown in the attached figures 1 and 2: the utility model provides a do not have to hinder trap of catching large-scale birds includes stay cord 1 and lays horizontal pole 2 on ground, and the lower surface and the ground of horizontal pole 2 are connected with the fastener, and the fastener includes vertical fastening bolt 3, and the upper surface of horizontal pole 2 is connected with a plurality of iron cores 4, and iron core 4 includes free end and stiff end, iron core 4's stiff end and 2 fixed connection of horizontal pole.

The free end of iron core 4 is equipped with first ring 5, and the stay cord 1 is tied on the surface of iron core 4, and stay cord 1 is connected with second ring 6, and wherein during second ring 6 was emboliaed first ring 5 to the one end that stay cord 1 kept away from, iron core 4 was passed in the 6 departments of stay cord 1 connection second ring, and stay cord 1 adopts two strands of rope establishment of intertwining each other, and 6 surface winding ropes of second ring.

Wherein second ring 6 pastes and leans on in the stiff end of iron core 4, and second ring 6 slides on iron core 4's surface, and when stay cord 1 level in horizontal pole 2, iron core 4 forms bow-shaped, and bow-shaped iron core 4 divides into a plurality of shares with horizontal pole 2 equidistant.

The bow shape comprises a bow body and a bow string, the bow body is an arched iron core 4, the bow string is a horizontal pull rope 1, an accommodating space 7 is formed between the bow body and the bow string, and when the shape of the bow body changes, the bow string slides along the bow body so as to change the size of the accommodating space 7.

The specific implementation process is as follows: this technical scheme utilizes the fastener to fix horizontal pole 2 and ground, thereby realize the stability of horizontal pole 2, fall this device area when avoiding birds to step on, consequently during fixed horizontal pole 2, squeeze into ground with outer screw 8 earlier, screw in the outside screw 8 of interior screw 9 afterwards, conflict to outer screw 8 after the bottommost at the in-process bolt tail of screwing, interior screw 9 of continuously screwing again, metal folded sheet 11 produces and buckles after interior screw 9 atress this moment, metal folded sheet 11 extends logical groove 10 this moment, the coverage of fastener has been expanded in the diversion, thereby realize firmly.
