Description

Description of the Invention

The invention relates to the trapping of small animals, in particular rodent rodents, and can be used for deratization.

Analysis of prior art

For catching tiny rodents such as mice, there are well-known mechanical devices that include a bait compartment, an entrance camera with a two-sided swinging platform, and a storage chamber. In the passage between the cameras is located a one-way action valve (or one-way valve that provides only one-way movement), which is connected to a rocking platform via a latch (patent RU94030152).

Known as a trap for catching rodents, which contains a rod collecting collar and a tipping trap, which is designed in the form of a bridge, to which is attached a plate with baits at its ends for attracting rodents. The bridge with its ends rests on the sides of the shell. The plate with the bait intersects (crosses) the bridge and is convex towards the shell. The center of gravity of the bait plate is located below the horizontal plane where the bridge support points are located on the edges of the hull. Between the plate elements and the closure element is a bait plate (patent RU2450514).

One of the drawbacks of these mechanical devices is the complexity of the setting, as well as the installation of bait and non-return valves. In addition, after pulling out one trapped rod, it is necessary to reset the device repeatedly once. Another problem with the use of mechanical devices is the need for regular cleaning, since the death of animals is accompanied by vomiting, diarrhea, etc. of various substances. as a result.

Mechanical traps (traps) are known for many improvements aimed at increasing the safety of the number of animals caught (patent US8499488) or of the shutter (lock) using photoelectric sensors (patent application CN102742566). Electronic traps are also created (patent RU2322807). However, the use of these devices is inefficient, complicated and therefore limited.

Devices for catching small rodents (such as Magpow's mouse traps) have recently gained widespread use and are of interest in the form of a polygonal platform, now simply referred to as a polygon, meaning solid material (cardboard or plastic). a polygonal platform with a layer of glue applied to it for fixing animals, etc. for placing the structural elements. The bait is installed in the center of the landfill. These mouse traps are easy to use as they do not contain mechanical parts. However, their efficiency is low, as the rodent can simply cut through a part of the landfill and leave it intact and intact. The device is particularly ineffective against relatively large rodent rats.

Purpose and substance of the invention

The object of the invention is to increase the efficiency of the use of the device. The stated aim is achieved at the expense of the small rodent catching device comprising a rigid material polygon and an adhesive layer for fixing the animals, the glue layer being applied to a flexible film which is connected to a tear-off polygon. The object is also achieved at the expense of the film being fixed to the landfill along its perimeter and articulated to one side of the landfill, whereby the elastic film can be formed in the form of a flexible film layer package with adhesive layers between separate film layers contact area of all film layers or only part of them).

The invention is illustrated by the accompanying drawings:

Figure 1 is a cross-sectional view of the basic embodiment of the proposed device, but

Fig. 2 is a schematic diagram of a film release.

The proposed device consists of a polygon 1 made of a rigid material (cardboard or plastic (plastic)) on which an adhesive layer 2 is applied. be attached to the landfill 1 on one side by a pivot 5. The landfill may have a package of flexible films 3 with layers of glue between them. The elastic film has a tensile strength (strength) in the range of 20 to 30 N / cm ² .

In the working position, the bait is positioned in the central part of the elastic film 3. As the rodent enters the film and tries to get rid of it, it releases the film from the pivot 5 and beyond, the animal wrapping / wrapping completely and causing the animal to die as a result of chaotic movements. The bait is then placed on the top layer of film 3 from the remainder of the packet that has retained its bond with the landfill. The device can be reused without additional bait placement if the glue contains attractive areas that attract rodents. This increases the efficiency of catching small rodents. Plus, the device is simple and easy to use.

It should be noted that, as a result of the use of the proposed device, the animal is practically wrapped in a film, which largely eliminates the aforementioned problem of cleaning mechanical devices.

Claims (4)

Claims An apparatus for catching small rodents, comprising a landfill 1 of a rigid material which is provided with a layer of glue 2 for fixing animals to it, characterized in that an elastic film 3 is attached to the landfill 1, which is connected to the landfill tearing is ensured by applying an adhesive layer 4 to the elastic film 3. Device according to Claim 1, characterized in that the film 3 is essentially attached to the landfill 1 only along its circumference. Device according to claim 1 or 2, characterized in that the film 3 is pivotally attached to the polygon 1 at one of its edges. Device according to any one of the preceding claims, characterized in that the resilient film 3 is formed by a bundle of resilient film layers with adhesive layers between the individual film layers (optionally with the glue layers on the whole or only part of the contact area of the film layers).
