Description

DESCRIPTION

Device for catching birds.

Technical sector

The present invention relates to a device for catching birds, especially suitable for population control of certain types of birds, mainly pigeons, by live capture.

Prior art

As part of the state of the art, it is worth mentioning the utility model ES 1058933 U, of the same holder of the present invention, in which a device for catching birds and animals is described, comprising an extensible network attached to projectiles and a pneumatic mechanism for launching said projectiles on a capture area, said pneumatic mechanism comprising air or gas pressure tanks connected by means of a discharge valve to projectile launch cannons.

In said antecedent each discharge valve comprises an actuation lever related to a crossbar connected with a pneumatic firing cylinder that causes the simultaneous opening of all the valves and the firing of the projectiles connected to the capture network; the air reservoirs of the respective guns being connected by means of respective non-return valves to a refill connector coupled to a common main tank, supply of the air or gas under pressure.

The connection of the collector to said common main tank is made by means of a pressure regulating valve that allows the load pressure of the device to be varied.

In said antecedent the cannons are housed inside a housing that has lateral handles for transport.

The owner of this background has detected the convenience of introducing some improvements in this type of devices aimed at simplifying the manufacture of the device, reducing the number of pieces and consequently the weight of the device, to simplify its operation, facilitate its manual transport and considerably reduce the cost of the materials necessary for its manufacture.

Another objective is to prevent the accidental death of birds, currently caused by the net during the capture of the birds.

Explanation of the invention.

The device for catching birds, object of this invention is of the type described in the preamble of the first claim, comprising: a support housing with a cavity for housing and transport of a capture net; cannons fixed to the housing and connected to pneumatic means responsible for supplying the pneumatic pressure necessary to fire projectiles attached to the capture network, causing the network to be launched over a capture area, and means for simultaneous firing of the canyons

This device has adequate characteristics to achieve the proposed objectives, that is: to facilitate its handling, simplify its manufacture, reduce the number of constituent parts thereof, the manufacturing cost, and its weight so that it can be easily transported.

To this end, one of the characteristics of this device is that the cannons are formed in pairs, by two straight ends of some “V” bent tubes, in this way it is possible to pneumatically feed a pair of cannons simultaneously, reducing to half the number of valves and feeding means used in the capture devices currently used.

The pneumatic means for feeding the guns comprise boilers provided with adapters suitable for coupling disposable gas pressure cartridges, said boilers being individually connected by means of a trip valve to the central zone of the respective forming tubes. cannon pairs

This feature allows you to use cartridges as a source of pneumatic pressure disposable, small volume, for example the typical CO2 cartridges used in compressed air guns, avoiding the use of a heavy and bulky external main tank, for the feeding of the barrels of the guns; and eliminating the risk involved in handling said external tank charged under pressure.

Additional advantages are also achieved since these types of disposable cartridges have a low cost, their placement and removal of the adapters is quick and easy, and their use does not carry a significant risk.

According to the invention, the trip means comprise a simultaneous actuation bar of the trip valves.

Said drive bar can be operated manually by means of a tilting arm mounted on an auxiliary structure fixed to the support housing or pneumatically, in person or remotely.

In this case, the actuation means comprise a pneumatic cylinder inserted in the valve actuation bar, and pneumatically connected to any one of the boilers by means of a solenoid valve that can be operated by means of a push button or by means of a remote control.

The remote drive allows the user to be hidden and away from the device, preventing its presence from negatively affecting the capture.

A further feature of the invention is to use a capture net with a mesh light equal to or less than 2 cm. This prevents pigeons from entering the head through the net and suffering unwanted damage during capture.

Brief description of the content of the drawings.

To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:

- Figure 1 shows a front elevation view of an embodiment of the device for catching birds according to the invention.

- Figure 2 shows a top plan view of the device of Figure 1.

- Figure 3 shows a profile view of the device of the previous figures partially sectioned by a vertical plane passing through the middle, curved area of the tubes forming the barrel pairs.

Detailed presentation of embodiments of the invention.

In the exemplary embodiment shown in the figures, the device for catching birds comprises a support housing (1) with a cavity (11) open frontally for the accommodation and transport of a bird capture network (2) that It has suitable projectiles on its periphery to be fired from the cannons and cause the network (2) to be launched and deployed over a capture area.

The cannons (3) are fixed to the housing (1) and connected to pneumatic means responsible for supplying them with the necessary pressure to fire projectiles (21) attached to the capture network (2) and launch said network (2) on a capture zone

The cannons (3) are formed in pairs, the straight end sections of tubes (31) bent in "V". The pairs of cannons (3) of the different tubes (31) form different angles from each other, so that the whole of the cannons (3) are arranged forming a fan on the housing (1), which allows the opening of the network (2) during its launch over the capture zone.

The pneumatic means for feeding the guns (3) comprise boilers (4) provided with adapters (41) suitable for the coupling of disposable pressurized gas cartridges, in this particular case of CO2.

As can be seen in figure 3, each boiler (4) is connected by means of a firing valve (42) to the central area of one of the tubes (31), providing the firing pressure to the pair of cannons (3 ) defined by said tube.

In said figure 3 the firing valves (42) of the different guns are vertically superimposed, and related to a bar (5) of simultaneous actuation, which is part of the firing means of the device.

Said bar (5) is coupled to a tilting arm (51) mounted on an auxiliary structure (52) and which, when manually operated, causes simultaneous firing of the cannons (3).

In the example shown, the firing means additionally include a pneumatic cylinder (53) intercalated in the actuating bar (5) and pneumatically connected to any one of the boilers (4) by means of a solenoid valve (54) operable by means of a push button or by a remote control (not shown).

As mentioned, the capture net (2) has a mesh light equal to or less than 2 cm. to avoid that during the capture the birds can introduce the head through the net and suffer damages.

Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
