Description

  The present invention relates to a pest capturing apparatus, and more particularly, a new pest capture with a capture net configuration that captures pests such as deer and spiders that cause damage to crops by using the behavior of the pests themselves. It relates to the device.

  Conventionally, as shown in Patent Documents 1 and 2 below, there have been proposed harmful animal capture devices using a capture net. The capture device of Patent Document 1 is configured to capture a pest by dropping a capture net that is deployed and suspended around a single column from the top when the pest invades. Further, the capture device of Patent Document 2 has a configuration in which when a pest invades on a capture net deployed and installed on the ground, it is lifted while the periphery of the net is squeezed to capture the pest.

Japanese Patent Laid-Open No. 2003-219784 Japanese Patent Laid-Open No. 2014-083049

  However, in the conventional pest capturing apparatuses described in Patent Documents 1 and 2, the capture operation of dropping or lifting the capture net is either mechanical or electric to detect the entry of the pest into the capture area. The configuration is started by the expression detecting means. These intrusion detection means have a complicated structure, and the installation of the entire capture device requires labor and skill, and always has a risk of failure or malfunction. That is, in the device of Patent Document 1, there is a concern that the engagement hook that locks the capture net in the suspended state cannot be removed due to failure or the like, and in the device of Patent Document 2, the infrared sensor for intrusion detection is other than a pest. There is a risk of malfunction due to optical path obstructions.

  An object of the present invention is to provide a new pest capturing apparatus using a capture net that has a simple structure that solves the above-described problems and has high capture accuracy. More specifically, it is an object of the present invention to provide a pest capturing apparatus that is inexpensive and easy to perform facility work to capture a pest that has entered a capture area in a self-locking manner using the movement of the pest itself. To do.

  In order to achieve the above-mentioned object, the pest capturing apparatus according to the present invention includes a tension line that is stretched at a ground position higher than the height of the pest to be captured, and a line threading tool at predetermined intervals around it. The trapping net that has been attached and the squeezing cord that has been passed through the threading tool of the capture net are configured as main members, and one side of the capture net is suspended from the stretched rope, and the opposite side is hung on the ground. The end of the choke is extended from one corner of the opposite side and fixed to prepare for capture.

  When the head of a pest hits a capture net hung on a tension rope, the upper side of the net slides from the tension rope to the back of the pest and automatically surrounds the pest. After that, when the beasts escape in the capture net, the surrounding rope is automatically drawn, and the pests are trapped and trapped in the capture net that gradually becomes a bag. .

  The mesh size of the capture net is the size that does not allow the head to come off according to the pests to be captured, but the mesh size in the range of about 1/5 the vertical lower side of the capture net that hangs on the ground It is preferable to use a relatively small mesh that is easily entangled with the pests of harmful animals. In addition, it is desirable that the upper half of the catch net is made up of relatively thick net yarn and the mesh is also small, and this weighted construction makes the rear side of the harmful animal effective when the catch net is pulled down. Can be surrounded.

  In addition, the pest capturing apparatus of the present invention includes a second capture net that is deployed and suspended above the rear part of the first capture net, and the suspended state of the second capture net is linked to the first capture net. The second feature is a configuration further comprising a pulling thread connected to the first catching net so as to be released. In the process where the head pest is caught by the first capture net, the pulling thread is pulled by the force applied to the first capture net, and the suspended state of the second capture net is released and dropped. To do. As a result, the accompanying pest following the leading pest can also be captured by the second capture net so as to be caught by the throwing net.

  Furthermore, the pest capturing apparatus of the present invention provides an intrusion detection line in the pest intrusion route of the first capture net, detects the invasion of the pest by breaking or tensioning the intrusion detection line, and transmits the pest chasing sound. The generated configuration is the third feature. As the driving sound generator, an existing electric or mechanical device such as a wake-up alarm can be used.

  According to the present invention, the capture is completed by the direct action of the pests themselves, and there is no need for complicated detection means and operation mechanism for detecting the intrusion action into the capture area as in the conventional case. It is possible to provide a capture device that is inexpensive and easy to perform facility work by skillfully using the behavior of the pests and the knowledge of the victims. Further, according to the second feature of the present invention, the first capture net hanging in the vertical direction and the second capture net suspended above the rear part are used to defeat the harmful beasts that act with them. Can be captured.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. For simplification of description, the same components are denoted by the same reference numerals in the drawings.
Embodiment 1

  Referring to FIG. 1, a capture net 1 that is a main body of a pest capturing apparatus according to the present invention has a square net shape with a side of about 3.5 meters, for example, so that facility work by one person is possible. . Robust fishing lines are suitable for the vertical and horizontal nets, but high-strength resin yarns such as No. 5 or No. 6 that have a transparent feeling that is not easily noticeable by harmful animals, especially PE yarns (polyethylene yarns) should be used. preferable. The size of the mesh will vary depending on the pests to be captured, but the pests will pass but not the head. In the case of deer, a mesh of 35 cm square is good, and in the case of a small animal such as a rabbit or a neutria, a small mesh of 10 cm to 20 cm is used.

  As a configuration of the capture net 1, it is preferable that the mesh size of two opposite sides in the vertical direction is different from the mesh size of the intermediate portion. That is, the range of the upper side 1a of about 1/5 of the vertical dimension is such that the weight per unit area is heavier with a relatively thick thick net yarn and small mesh. On the other hand, the range of the lower side 1b of about 1/5 of the vertical dimension is a mesh smaller than the mesh of the middle part so that the leg of the capture target pest is easily entangled. The mesh material in the range of the upper side 1a and the lower side 1b is preferably thick and heavy.

  As shown in FIG. 2, ring-shaped threading tools 2 are attached around the capture net 1 at predetermined intervals. The cord threading tool 2 is a solid and heavy ring made of metal or resin, but it is preferable that the cord threading tool 2 has a smooth surface that is easy to slide with respect to the choke string passing through the ring.

  A string 3 around the capture net 1 is passed through the string threading tool 2. As the narrow cord 3, a high-strength B-type piano wire or PE line (preethylene yarn) is suitable. A ring fitting (not shown) is fixed to one end portion of the string 3 drawn out from one corner of the lower side of the capture net 1, while the other end portion is extended through the ring fitting, and the extended end portion is made up of a standing tree or It can be tied to a strong pile.

  FIG. 3 schematically shows a state in which the capture device of the present invention is mounted, and a tension rope 5 as another component member is stretched substantially horizontally on the ground of the capture area. The tension cable 5 is also preferably a slippery metal or resin high strength wire having a smooth surface. For the stretch of the rope 5, a pole or a natural tree 6 standing in the capture area is used, and the height is higher than the height of the harmful animal and about 70% of the vertical dimension of the capture net 1 is appropriate. That is, if the length of the side of the capture net 1 is 3.5 m, the height of the tension rope 5 is preferably about 2.5 m.

  As shown in FIG. 3, after the tension of the tension cable 5 is finished, the upper side 1a of the capture net 1 is set on the tension cable 5 and the opposite lower side 1b is set to hang on the ground. The direction of suspension of the capture net 1 is such that the upper side 1a extends beyond the stretched line from the front of the direction in which the harmful animal 8 enters. Further, the free end of the narrow rope 3 extending from one corner of the hanging side 1b of the capture net 1 is fixed and fixed to a fixing means 6 such as a standing tree. In this state, the upper side 1a of the catching net 1 hangs down about 50 cm on the side of the stretched rope 5 facing in the direction of the harmful animal invasion, and the opposing hanging side 1b spreads on the ground on the near side in the direction of the harmful animal invasion. You are now ready to capture.

  FIG. 4 shows the state of the first step of the capturing action. That is, when the beast 8 invades in front of the capture net 1 that has been prepared for capture as described above, hits the head against the capture net 1 and steps on the small drooping side 1b of the mesh, the rushing force causes FIG. As shown in Fig. 4, the catch net 1 is pulled off from the suspension rope 6, and the upper side 1a is dropped so as to surround the rear side of the harmful animal 8 together with the surrounding rope 2 and the weight of the heavy mesh thread. To do.

FIG. 5 shows the state of the second step of the capturing action. That is, when the harmful animal 8 entangled with the small lower side 1 b of the net of the capture net 1 causes escape behavior, the force becomes a force for pulling the narrow rope 3 around the capture net 1. Therefore, the more the harmful animal tries to escape, the more gradually the periphery of the capture net 1 is squeezed by the narrow rope 3 with the end fixed, and finally the harmful animal 8 is captured by the capture net 1 as shown in FIG. It is completely trapped inside. Thus, the capture operation using the behavior of the harmful animal 8 itself is completed.
[Embodiment 2]

  By the way, pests such as deer and moths that damage agricultural crops and forests have a habit of acting with several animals, and there is a concern that the trapping apparatus of the first embodiment may miss the following pests.

  FIG. 6 is a schematic perspective view showing a second embodiment of the pest capturing apparatus according to the present invention for eliminating such anxiety.

  As shown in FIG. 6, a second capture net 10 is suspended above the rear portion of the first capture net 1 of the first embodiment. Similarly to the first capture net, the second capture net 10 has a configuration in which a second narrow rope 11 is provided in the periphery, and the four corners of the second capture net 10 are substantially the same as the tension cable 5 by using surrounding trees. It is suspended by a hanging rope 12 at a height above ground. 7 is attached to the hanging rope 12, and hooks 15 provided at the four corners of the second capture net 10 are hung and held in a suspended state.

  That is, as illustrated in FIG. 7, the connecting tool 13 for suspending the second capture net 10 includes a U-shaped or C-shaped metal fitting 13 a and an opening / closing pin 13 b that closes the release end. The base of the metal fitting 13 a is coupled to the end of the suspension rope 12, and the open / close pin 13 b is coupled to the pulling thread 14. In the capture preparation state, the hooks 15 at the four corners of the second capture net 10 are in a state of being locked to the opening / closing pins 13b.

  Accordingly, the extended end of the second choke line 11 of the second catching net 10 is tightly fixed to the pile or the standing tree 6, and the end of the pulling thread 14 is tied to a part of the first catching net 1, for example, the upper side 1a. In this case, the pulling thread 14 is pulled in conjunction with the fall of the first capture net 1, whereby the opening / closing pin 13 b is pulled out and the suspended state of the net by the hanging rope 12 is released. As a result, the second catching net 10 falls from above the first catching net 1 and can catch the following harmful pests that act together.

Further, if the pulling thread 14 for releasing the connection of the suspended rope 12 to the second capture net 10 is connected to the narrow rope 3 of the first capture net 1, the second capture net 10 is connected to the first capture net 1. It can be dropped with a time difference from when it is dropped to when the force is applied to the squeezed rope 3, and the subsequent companion pests can be captured more effectively.
[Embodiment 3]

  FIG. 8 is a schematic perspective view showing a third embodiment of the present invention. In this third embodiment, the intrusion detection line 16 is stretched at such a height that the harmful animal touches the harmful animal intrusion route of the first catching net 1 installed so as to hang substantially vertically. The intrusion detection line 16 is connected to a sound generator 18 for driving a pest through a spring 17. The spring 17 may be replaced with an elastic member such as a rubber band.

  In the sound generator 18, the lever 18a is operated in the direction of the arrow by the reaction contraction force of the spring 17 when the intrusion detection line 16 is broken, and a built-in buzzer or bell (not shown) is activated to generate sound. Pests approaching the capture area will be surprised by the sound that suddenly occurs from behind when the intrusion detection line 16 is broken by their own action, and will be automatically driven to the front capture net, increasing the rushing force. The capture action is more reliable.

  As the intrusion detection line 16, it is necessary to select a material that takes into account the balance between the tension of the spring 17 that accumulates the actuation force of the lever 18 a and the strength to break by the force of the invading action of the pest. Alternatively, the central part of the intrusion detection line 16 may be connected to each other by a connecting tool such as a key hook, and the key hook may be released by the contact force during the invasion action of a harmful animal. As the driving sound generator 18, an existing configuration such as a battery-type or mechanical type alarm can be used as appropriate.

  As is clear from the above description, according to the pest capturing apparatus of the present invention, it is possible to effectively use the pest's own actions without the need for complicated mechanisms or electrical detection means. Beasts can be captured. In addition, the capturing device of the present invention is easy to install and has the advantage that no special knowledge or skill is required for the operation or operation. Therefore, the present invention can prevent damage to pests at a low cost, and is extremely useful for agricultural and forestry workers who suffer from damage to pests such as deer and moths.
