Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mole trapping apparatus which reliably captures moles living in the ground. 2. Description of the Related Art As a device for capturing underground moles,
For example, there is one described in JP-A-11-206304. The conventional mole capture device receives a needle-like sharp portion at the tip of a piercing member that is urged to descend by a coil spring with a round bar trigger member,
The needle-like sharp portion is removed by the rotation of the trigger member when the actuating auxiliary member with which the mole contacts is actuated, and the piercing member is lowered by the bias so that the needle-like sharp portion pierces the mole. [0003] However, in the above-mentioned conventional catching device, the piercing member is only locked by the trigger member of a round bar. When the trigger member is rotated by the vibration caused by the vibration, the piercing member is lowered by the urging, and the idle member is hit. Moreover, since the locking of the piercing member is unstable as described above, there is a danger that the piercing member may operate unexpectedly during installation and pierce the operator. Further, since the coil spring is in an extended state and urges the piercing member by a contracting force at the time of operation, a high urging force cannot be expected, so that reliable capture cannot be expected. Therefore, an object of the present invention is to provide a capturing device which can reliably capture by a very simple structure and which does not deteriorate its capturing function even if it is installed outdoors for a long time. [0004] In order to achieve the above object, the present invention provides a piercing needle bar provided on a lower surface of a vertically movable member which can move up and down along a vertical guide frame, and an upper surface of the guide frame. The lifting mechanism is removably fastened by the operating mechanism provided in the above, a sensor mechanism provided on the lower side of the guide frame is connected to the operating mechanism, and the operating mechanism is operated by the detection of the sensor mechanism to move up and down. The locking of the member is released, and the lifting member is rapidly lowered along the guide frame by urging so that the mole near the sensor mechanism is pierced by the piercing needle and captured. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the drawings. FIG. 1 is a schematic perspective view showing an embodiment of the present invention, FIG. 2 is a side view partially in section, FIG. 3 is a front view partially in cross section, FIG.
FIG. 5 is a front view of a state in which the mole has been captured. In the mole trapping device 1 of the present invention, a lifting member 3 is provided on a frame 2 so as to be vertically movable, and the lifting member 3 is detachably secured to an operation mechanism 4 provided on the upper surface of the frame 2. Then, a sensor mechanism 5 provided below the frame 2 is connected to the operating mechanism 4, and the sensor mechanism 5
Is activated, the lifting member 3 is suddenly moved down to catch the rouge. [0007] The frame 2 is a vertical guide in which a pair of left and right vertical members are provided on the upper surface of a base frame 21 in which a pair of left and right square members are vertically assembled in a cross-shaped manner so as to oppose at a certain interval. A frame 22 is provided, and a flat top frame 23 is provided at an upper end of the guide frame 22. A through hole 24 is opened at a substantially central position of the top frame 23. Is provided with a bearing 25. A pair of latching rods 26 are provided upright on one side of the top frame 23. The elevating member 3 is vertically movable inside the guide frame 22 and has a weight of about 3 kg, and is urged to drop rapidly by its own weight. On the lower surface of the elevating member 3, a plurality of piercing needle rods 31 each having a needle-like lower end are provided downward, and a hanging member 32 is provided upright on the upper surface, and one end is attached to the hanging member 32. The connected suspending member 33 is inserted into the through hole 24 and positioned above the top frame 23, and a grip portion 34 is provided at the other end of the suspending member 33 to be located on the upper surface of the top frame 23. Normally, the grip portion 34 is hung on the hanger rod 26. The operating mechanism 4 is provided with an operating piece 44 on a rotating shaft 43 of a speed reducer 42 integrally provided with a motor 41 electrically connected to a battery (not shown).
An operating portion 46 provided at one end of an operating rod 45 pivotally attached to the bearing portion 25 is positioned within a rotation range of the operating piece 44, and a receiving portion 47 provided at the other end of the operating rod 45. In this configuration, the hanging member 32 is detachably fastened. A hook-shaped engaging portion 48 is provided in the middle of the operating rod 45 so as to be located between the bearing portion 25 and the operating portion 46.
By locking the upper surface of 5, the operating rod 45 is prevented from turning upward. However, since the operating rod 45 is loosely pivotally attached to the bearing 25, it can be shifted in the left-right direction. Therefore, when the operating portion 46 is impacted from the lateral direction by the operation piece 44, the operating rod 45 can be disengaged from the locking portion 48 and can be rotated upward. The sensor mechanism 5 includes an L-shaped connecting rod 5.
A sensor part 52 formed in a ring shape at the lower end of the lower part 1;
A switch mechanism 53 provided on an arm 27 extending laterally from a side surface of the guide frame 22; and a wiring unit 5 for electrically connecting the switch mechanism 53 and the motor 41.
The upper end of the connecting rod 51 is pivotally mounted on the arm 27. When the connecting rod 51 is stationary, the switch mechanism 53 is off and the motor 4
1 is stopped. However, when the connecting rod 51 swings, the switch mechanism 53 is turned on, the motor 41 is driven, the rotation shaft 43 of the speed reducer 42 is rotated, and the operation piece 44 is rotated. In addition, the sensor unit 52 is connected to the guide frame 22.
It is located below. The catching device 1 of the present invention has the above-mentioned structure. In use, the catching device 1 is installed on the ground surface at a position where the mole is protruded and retracted, and the ground surface is dug shallowly to form a lower portion of the connecting rod 51 and a sensor portion. Insert 52. Then, the suspending member 33 is pulled up by the grip portion 34 and the upper portion of the suspending member 32 is passed through the through hole 2.
4 and raised above the top frame 23, and is locked to the receiving portion 47 of the operating rod 45. In this state, the middle of the operating rod 45 is
8, the operating rod 45 is stable without rotating due to the weight of the lifting member 3. The motor 4
1. The switch mechanism 53 is connected to the electric circuit of the battery, and since the switch mechanism 53 is off, the motor 41 is not driven. Therefore, it is in a capture waiting state of the mole. When the mole rises from the ground to the ground surface, it comes into contact with the sensor part 52 of the sensor mechanism 5, so that the connecting rod 51 swings, and the switch mechanism 53 is turned on. When the motor 41 is driven and the motor 41 is driven, the operating piece 44 is rotated via the speed reducer 42, and the operating part 46 is jumped in the horizontal direction.
It comes out of the free state. Therefore, the operating rod 45 is rapidly tilted by the elevating member 3 so that the operating part 46 is raised, and
Since the second member 2 is removed from the receiving portion 47, the lifting member 3 can be rapidly lowered by its own weight and pierced, and the needle 31 can be captured by penetrating the mole near the sensor portion 52 from above. In this case, the lowering position of the elevating member 3 is regulated by the soil, but the state in which the suspending member 33 is fully extended while the grip portion 34 is hung on the hanger rod 26 is the lowest position. In the above-described manner, when the mole is captured, the mole of the piercing needle rod 31 can be removed simply by holding the capturing device 1, so that the operating rod 45 is locked by the locking portion 48.
The capture device 1 is installed on the ground surface,
Can be used again simply by raising the lifting tool 32 and hooking it on the receiving portion 47. The motor 41 may be provided with a power on / off switch separately connected in the middle of the wiring section 54. However, if the operating rod 45 and the locking portion 48 are connected in the middle of an electric circuit as a power switch, the locking portion 4
8 is turned on when the operating rod 45 is locked, and turned off when the operating rod 45 is released, so that the power supply to the motor 41 is stopped at the moment when the operation piece 44 jumps the operating portion 46 in the lateral direction by driving the motor 41. So it is practical. Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, but may be implemented in any manner unless the structure described in the claims is changed. can do. For example, a vertical guide frame was formed into a cylindrical shape, and an elevating member made of a disc material was provided inside, and a strong coil spring was provided between the elevating member and the lower surface of the top frame.
