The bird trapper can simply trap the birds normally taking food on ground without damage, to support the research on bird.

Description

There is not injury catching bird net cage

Technical field:

The utility model belongs to the catching bird device that carries out birds research, is specifically related to a kind of device that the birds of the ground feeding activity of being everlasting are caught in injury that do not have.

Background technology:

Sticking net (claim the mist net again or throw the net) is that the research and the ring will catching bird instrument that use the most generally accepted in present countries in the world, and this catching bird instrument mainly is to be applicable to glue to catch aloft birds, is unsuitable for catching the birds of land operations.Being used to catch the be everlasting instrument of land operations birds mainly contains The button net, Turn over net, the impelling net, step on cage, clap cage etc., these instruments all are the catching bird instruments that the ecological habit at different birds is made, but utilize these catching bird instruments all can damage institute's catching bird class in varying degrees.

Summary of the invention:

The purpose of this utility model provides the device that the birds of the ground feeding activity of being everlasting are caught in a kind of nothing injury of carrying out birds research.

The utility model draws column by 4 two, and 43 are drawn cross bar, 5 nets, 1 spool control gate and the backguy of spool control gate to constitute.Connection between column and the cross bar is fixed by drift bolt, and the sheet net directly is tied to cross bar and column gets final product.The height of column and the length of cross bar can be controlled as required.

The utility model energy is more convenient, the birds of ground feeding activity are caught in the nothing injury, for the research to bird provides the condition that makes things convenient for.

Description of drawings:

Fig. 1 does not have injury catching bird net cage overall structure schematic diagram;

Fig. 2 does not have injury catching bird net cage column and cross bar joint schematic diagram.

Wherein each parts is: column 1, the U-lag 6 on cross bar 2, net 5, control gate 4, backguy 5, column top, cross bar carefully hold 7, cross bar butt end 8, drift bolt 9.

Embodiment:

This utility model is made of 1, four cross bar of four columns 2, five nets 5 and spool control gate 4 and backguy 5.Column 1 is made of two sections pull bars, and is scalable.Column 1 upper end is fixed with the U-lag 6 that side direction is placed, and there is perforation in last bottom.Cross bar 2 is made of three sections pull bars, and is scalable.Cross bar 2 two ends are flat, and are provided with perforation.Butt end 8 and thin end 7 horizontal hanging together that cross bar 2 is with holes during installation are inserted in the U-lag 6 on column 1 top, fix with drift bolt 9 then, and other three columns 1 connect identical therewith with 2 of cross bars.Net 3 directly is tied on cross bar 2 and the column 1 and gets final product.The length of the height of column 1 and cross bar 2 can be controlled as required.Spool control gate 4 directly is fixed on ground.Install as shown in Figure 1 during use, in net, put into corresponding bait according to the object that will catch then, bait is thrown in a side opposite with spool control gate 4, the operator holds draught line 5 and observes in the shelter, treat to utilize after bird networks backguy 5 with 4 sealings of spool control gate, can under the condition that birds is not damaged, catch the birds of the ground feeding activities such as grassy marshland, grassland, slash, border of being everlasting, as magpie, crow, titmouse, Bunting class etc.
