Moletrap

Description:

The invention relates to devices for combating mumps.

The trap is known, representing a metal device with six spindle-shaped pivots, actuated by a spring and an arm [1].

In order to place the trap in the ground, the mole-digging tunnel must be pressed with the foot so that the roof of the tunnel is moved down. The arm is installed under the tunnel. When passing the mole through this place it will raise the roof with its back, thus acting on the trap arm.

The shortcoming of the known trap is that in many cases the mole does not raise the earth by sliding through the tunnel or, being disturbed by the observed changes, it blocks this segment of tunnel with earth, which makes the arm difficult to operate. Thus the ability to fight mumps is low.

The problem solved by the proposed invention is to increase the efficiency of combating mumps.

The hatch trap, according to the invention, includes a rectangular frame with legs, on the lower and upper sides of which coaxial holes are executed, a mechanism of destruction and a trigger mechanism. The elimination mechanism consists of a needle with fastener, an arc for pressing the needle with the ends joined to two parallel plates. The needle is coaxially located in the holes with the possibility of vertical displacement. One of the plates is fastened to the lower side of the frame, and the other plate is joined to the upper end of the needle. The trigger mechanism consists of a hinge with fastener, one end of the arm is provided with a metal plate, and the other end is joined to the upper side of the frame by means of a bush. The needle and arm fasteners are made with the possibility of interaction between them.

The mole trap is based on the mule instinct not to withstand light and air currents. Thus, if the tunnel is uncovered or damaged, the mole will immediately try to block or block it with the earth inside the tunnel. Namely, the ground pushed by the mole presses the trigger of the trap, which catches the mole.

The advantage is that the constructive elements of the trap are not located or at least seen in the tunnel, which would cause fear or restlessness of the mules.

The result is to increase the efficiency of combating mumps.

The trap includes a rectangular frame 1 with legs 2. In the lower and upper sides of rectangular frame 1 coaxial holes are executed. The trap also includes a destruction mechanism and a trigger mechanism. The destruction mechanism consists of a needle 3 with fastener, a spring 4 for pressing the needle 3 with the ends joined to two parallel plates. The needle 3 is coaxially located in the holes with the possibility of vertical displacement. One of the plates is fixed to the lower side of the frame 1, and the other plate is joined to the upper end of the needle 3. The trigger mechanism consists of a bolt 5 with fastener. One end of the arm is provided with a metal plate 6, and the other end is joined to the upper side of the frame by means of a bush. The needle and arm 7 fasteners are made with the possibility of interacting with each other.

The invention is explained by the drawings in fig. 1 -2, which represents:

FIG. 1, the proposed trap;

FIG. 2, the trap installed at the end of the tunnel.

For the installation of the trap at the end of the tunnel or in place of the dirt bank, dig the о pit with a length of 30 ... 40 cm, to access the light and air flow. The trap is installed at 6 ... 10 cm from the end of the tunnel or of the open place, being stuck in the ground on the two legs 2. Needle 3 is fixed in the "ready to attack" position. The mole comes to plug its hole, it withstand light and air flow. Thus, it pushes the earth inside the tunnel, which reaches the metal plate 6 of the arm of the trigger mechanism. As the needle fixing mechanism and the trigger mechanism arm are made with the possibility of interaction between them, the needle pierces the mole.

The trap can also be installed in place of the stream, preventively liquidating it, but in this case two traps must be installed, the tunnel having extensions in two opposite directions.

In order to increase the clamping capacity instead of an arrow, three can be executed.
