Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mole capturing device, and more particularly, to a mole capturing device having a mechanism that automatically operates to pierce a mole when the mole enters a predetermined passage.

[0002]

[Prior art]

 Mole is generally considered a harmful animal for agriculture. This is because moles feed not only on crops but also on earthworms, which contribute to soil fertility. For this reason, it is common practice in the agricultural field to capture moles.

Conventionally, there is a mole capturing device having a mechanism for piercing a mole. The mechanism for piercing the mole is configured to operate automatically when the mole enters a predetermined passage. Also, when the intrusion of a mole into a predetermined passage is detected, this mechanism is usually caused by the bias of a spring so that the mechanism is immediately activated with sufficient force to pierce the mole. ing.

[0004]

[Problems to be solved by the invention]

 However, in the mole capturing device in which the mechanism for piercing the mole is operated according to the bias of the spring, the problem of deterioration of the spring is encountered. In other words, since this type of mole trapping device is installed outdoors, the spring rusts and the urging force decreases over time, and the mechanism for piercing moles is accurately provided. There may be situations that cannot be activated.

[0005] Therefore, an object of the present invention is to provide a mole capturing device improved so that a mechanism for piercing moles can be properly operated for a long period of time.

[0006]

[Means for Solving the Problems]

 According to this invention, in order to solve the above-mentioned technical problem, a mole capturing device having the following configuration is provided. That is, the mole capturing device according to the present invention has a main body part whose bottom end is buried in the soil so as to form a horizontally oriented passageway in the soil through which moles to be captured can pass. Is provided. An intermediate portion of the detection rod is attached to the main body portion so as to be rotatable around an axis line extending in the horizontal direction. The sensing rod is arranged in relation to the above-mentioned passage while one end thereof is buried in the soil. Also, the weight is held by the main body portion so that the weight falls toward the passage from above one end of the detection rod. The weight is attached with multiple needles for piercing moles facing downward.

Further, the mole capturing apparatus includes a locking lever for maintaining the weight lifted to an upper position. The locking lever has a middle portion rotatably held with respect to the main body portion, and one end of the locking lever can be engaged with the weight. A state of engagement and a state of non-engagement are selectively realized. A first end of a flexible linear body is connected to the other end of the locking lever. The upper end of a support rod extending in the up-down direction is connected to the second end of the linear body. Further, a guide member for guiding the linear body so as to provide a return path is attached to the main body.

[0008] In the mole capturing device having such a configuration, in a state of waiting for the mole, the weight is maintained in a state of being lifted to an upper position by the engagement of the locking lever with the weight. In order to maintain the state in which the locking lever is engaged with the weight, the lower end of the support rod is placed on the other end of the detection rod, and the linear body is temporarily lowered from the upper end of the support rod. In a state where the weight is guided by the guide member and then turned upward by the guide member, the tension is always maintained by the gravity from the weight via the locking lever.

On the other hand, when the mole enters the passage, the one end of the detection rod is displaced upward, so that the other end of the detection rod is displaced downward, and accordingly, the support rod and the linear member are displaced. As the second end is displaced downward and the first end of the linear body is displaced upward, the locking lever pivots so as not to engage the weight, and as a result, , Weights fall. A plurality of needles are displaced downward as the weight falls, and a mole is pierced.

In the present invention, in response to the downward displacement of the other end of the detection rod as described above, the lower end of the support rod placed on the other end of the detection rod can be easily adjusted by the detection rod. It is preferable to be configured so as to be disengaged from the other end. In the present invention, in a state in which the detection rod waits for the mole, it is preferable that one end of the detection rod is inclined so as to face downward from the center of rotation. This tilt angle is selected to be, for example, about 45 degrees with respect to the horizontal plane.

In the present invention, preferably, an inverted U-shaped handle is provided on the upper surface of the weight. Further, it is preferable that the mole capturing device according to the present invention further includes a safety member that can be selectively fixed to the main body portion while being inserted into such a handle. In the invention, it is preferable that the main body includes a closing member that closes a lower surface of the passage.

[Embodiment of the invention]

 FIGS. 1 to 6 illustrate a mole capturing device 1 according to an embodiment of the present invention. Here, FIG. 1 is a perspective view showing the entire appearance of the mole capturing device 1, FIG. 2 is a longitudinal sectional front view of the mole capturing device 1, and FIG. 3 is a plan view of the mole capturing device 1. . FIGS. 4, 5 and 6 are referred to when explaining the operation of the mole capturing apparatus 1. FIGS. 4 and 5 correspond to FIG. 2, and FIG. It is a figure corresponding to a part.

The mole capturing apparatus 1 includes a main body 2 having, for example, a cylindrical shape as a whole. The main body 2 can be manufactured by processing bamboo, for example. When the main body 2 is made of bamboo, which is a natural material, the mole capturing device 1 can be installed outdoors without any discomfort. The body 2 has a horizontal passage 4 through which the moles 3 to be captured (see FIG. 4) can pass. 2, 4 and 5, the ground 4 is formed in the soil as shown by the dashed line, so that the main body portion 2 has a lower end portion. It is installed buried in the ground.

In connection with the above-described passage 4, the main body 2 is provided with, for example, a plate-shaped closing member 6 for closing the lower surface side of the passage 4. At a relatively lower portion of the main body 2, for example, a rectangular through hole 7 is provided, and a detection rod 8 is arranged so as to pass through the through hole 7. As shown in FIGS. 2, 4 and 5, the detecting rod 8 has its intermediate portion rotatably attached to the main body 2 by a pivot pin 9 which gives an axis oriented in the horizontal direction. One end 8a of the detection rod 8 is disposed in relation to the passage 4 while being buried in the soil.

It is preferable that the detection rod 8 is buried in the ground in a state where one end 8a thereof is inclined downward from the center of rotation given by the pivot pin 9. This inclination angle is selected to be, for example, about 45 degrees with respect to the horizontal plane. Further, the weight 10 is held by the main body portion 2 so as to drop from above the one end 8a of the detection rod 8 toward the passage 4. In this embodiment, the weight 10 has a cylindrical shape and is disposed inside the cylindrical main body portion 2, and the main body portion 2 allows the one end 8 a of the detection rod 8 to pass from above through the passage, as described above. You will be guided to fall toward 4. The weight 10 is attached with a plurality of needles 11 for piercing the mole 3 facing downward.

More specifically, in this embodiment, the weight 10 is made, for example, by hardening concrete. Before the concrete hardens, the screw shaft 12 shown in FIG. 2 is embedded so as to protrude from the lower surface of the weight 10. On the other hand, a holding plate 13 for holding a plurality of needles 11 is prepared. On the holding plate 13, the needles 11 are arranged in two rows of five needles. By penetrating the screw shaft 13 through the holding plate 13 and screwing the nut 14 onto the screw shaft 12, the holding plate 13 is fixed on the lower surface of the weight 10, and as described above, a plurality of needles are provided. 11 is attached to the weight 10 in a state where it is turned downward.

An opening 15 for forming the above-described passage 4 at a lower portion thereof is formed in the main body portion 2 so as to extend relatively vertically. The side edge of the opening 15 also has a function of guiding the structure from the weight 10 to the needle 11 so as not to rotate around its axis when moving within the main body 2. That is, the holding plate 13 projects outward from the opening 15, and the holding plate 13 is provided with a guide rod 16 projecting in a direction orthogonal to the direction in which the holding plate 13 projects. . Therefore, when the structure from the weight 10 to the needle 11 tries to rotate around its axis, the rotation is restricted by the holding plate 13 and the guide rod 16 contacting the side edges of the opening 15. .

Further, the mole capturing device 1 is provided with a locking lever 17 for maintaining the weight 10 in a state of being lifted to an upper position, as shown in FIGS. The locking lever 17 has one end 17a which can be engaged with the weight 10. More specifically, an inverted U-shaped locking member 18 is provided on the upper surface of the weight 10, and one end portion 17 a of the locking lever 17 can be engaged with the locking member 18. You. The locking lever 17 is rotatable via the pivot pin 19 with respect to the main body 2 in order to selectively realize the state of engagement with the locking member 18 and the state of non-engagement. The middle part is retained.

A first end 20a of a flexible linear body 20 made of, for example, a string or a thick thread is connected to the other end 17b of the locking lever 17 described above. Next, the upper end 21a of the support rod 21 extending in the vertical direction is connected to the second end 20b of the linear body 20. The support bar 21 can be made of, for example, a thick wire or a wooden bar.

A guide member 22 extending in a U-shape, for example, is mounted on the outer surface of the main body 2 and at a substantially intermediate portion in the height direction. The guide member 22 is for guiding the linear body 20 so as to provide a return path. The mole waiting state of the mole capturing device 1 having such a configuration is shown in FIG. 1, FIG. 2 and FIG.

As shown in these drawings, in the mole standby state, the weight 10 is lifted to an upper position, and in order to maintain this state, one end 17a of the locking lever 17 is engaged. The state is engaged with the stopper 18. In order to maintain the posture of the locking lever 17 in this locked state, the lower end 21b of the support rod 21 is placed on the other end 8b of the detection rod 8, and the linear body 20 is moved. The support rod 21 is once folded downward from the upper end 21a, and then folded back by the guide member 22 so as to be guided upward.

At this time, since the gravity from the weight 10 is transmitted to the locking lever 17 and acts to displace the other end 17b of the locking lever 17 upward, the linear body 20 is always in the tension state. Is kept. When the linear body 20 is kept in such a tensioned state, a force for displacing the support rod 21 downward is exerted, and therefore, the detection rod 8 is moved counterclockwise in FIG. Although a rotating force is exerted, the one end 8a of the detection rod 8 is buried in the soil as described above, so that the detection rod 8 may be undesired in such a mole waiting state. It does not rotate counterclockwise.

In the above-described mole waiting state, when the mole 3 enters the passage 4 as shown in FIG. 4, the following operation is achieved in the mole capturing device 1. The posture of the detection rod 8 in the mole waiting state shown in FIG. 2 is indicated by an image line in FIG. In such a standby state, when the mole 3 enters the passage 4, the mole 3 touches one end 8 a of the detection rod 8 or the soil is raised due to the presence of the mole 3, and the solid line in FIG. As shown by, one end 8a of the detection rod 8 is displaced upward, and accordingly, the other end 8b is displaced downward.

Due to the downward displacement of the other end 8 b of the detection rod 8 described above, the support rod 21 and the second end 20 b of the linear body 20 are displaced downward. This allows upward displacement of the first end 20 a of the linear body 20, while, on the other hand, the gravity from the weight 10 causes the first The first end 20a is displaced upward, since it is always exerted on the end 20a.

At this time, since the gravity from the weight 10 is always exerted on the locking lever 17, the upward displacement of the first end 20a of the linear body 20 as described above causes the engagement. The stop lever 17 rotates clockwise in FIG. 2, and finally rotates until the lock lever 17 does not engage the lock 18. As a result, the weight 10 loses the support for maintaining it in a state of being lifted to the upper position, and falls as shown in FIG. In response to the drop of the weight 10, the needle 11 drops so as to block the passage 14 and pierces the mole 3 that has entered the passage 4.

The operation from the rotation of the detection rod 8 to the fall of the weight 10 as described above is achieved substantially instantaneously, but in this embodiment, the other end 8b of the detection rod 8 In response to the downward displacement, the lower end 21b of the support rod 21 placed on the other end 8b is easily detached from the other end 8b of the detection rod 8 as shown in FIG. It is composed of That is, since the lower end 21b of the support rod 21 and the other end 8b of the detection rod 8 are merely in contact with each other with a small area, the other end 8b of the detection rod 8 is slightly displaced. For example, the lower end 21b of the support rod 21 easily comes off the other end 8b of the detection rod 8 as shown in FIG. Therefore, the sensitivity of the detection of the mole 3 by the detection rod 8 can be further increased, and the probability of capturing the mole 3 can be further increased.

As described above, when the weight 3 is detected so that the mole 3 is detected and pierced by the needle 11, the weight 10 appears in the opening 15 provided in the lower half of the main body 2. The state can be visually recognized even from a relatively long distance. For example, even when a large number of mole capturing devices 1 are installed over a wide area, it is easy to monitor the individual mole capturing devices 1 and the treatment after capturing the moles is quick. You will be able to

As described above, the needle 11 pierces the mole 3 with the fall of the weight 10. In this embodiment, the closing member 6 is provided so as to close the lower surface of the passage 4. As a result, the mole 3 can be prevented from escaping further into the soil. Further, since the needles 11 are arranged in two rows by the holding plate 13, even if the moles 3 are not pierced by the needles 11, the moles 3 can be confined between the rows of the needles 11. Also, the probability that the mole 3 escapes can be reduced.

After the capture of the moles 3 is completed, the moles 3 are removed from the needles 11 and are again in a mole waiting state as shown in FIG. 1 or FIG. As described above, the following operation is performed to return to the mole waiting state. First, the weight 10 is lifted to an upper position. In this embodiment, the inverted U-shaped handle 23 is provided on the upper surface of the weight 10, so that the weight 10 can be easily lifted by grasping the handle 23.

In the above-described state, in order to prevent the weight 10 from being inadvertently dropped, as shown in imaginary lines in FIG. 3 and as shown in FIG. 6, for example, a bar-shaped safety member 24 is inserted into the handle 23. While being fixed to the main body 2. In this embodiment, a through hole 25 is provided at the upper end of the main body portion 2 to allow the safety member 24 to pass therethrough. By inserting the safety member 24 into the through hole 25, the safety member 24 Fixed. Note that the safety member 24 may be simply bridged over the upper end face of the main body 2 without providing the through hole 25.

As described above, in a state where the weight 10 is prevented from being accidentally dropped by the safety member 24, one end portion 17 a of the locking lever 17 is engaged with the locking member 18 as shown in FIG. As described above, the one end 8a of the detection rod 8 is buried in the soil, and the lower end 21b of the support rod 21 is placed on the other end 8b of the detection rod 8 as described above. Thereafter, when the safety member 24 is pulled out, the linear body 20 becomes in a tension state, and the above-described mole waiting state is obtained again.

[0032]

[Effect of the invention]

 As described above, according to the present invention, the mechanism for piercing the mole, that is, the mechanism for operating the needle toward the mole in response to the intrusion of the mole, is driven by gravity from the weight. The urging force does not deteriorate over time as in the case where the needle is used as a driving source, so that the needle can always be properly operated over a long period of time.

In the mole waiting state, one end of the detection rod is arranged in relation to a passage through which moles can pass while being buried in the soil, and the lower end of the support rod is connected to the lower end of the detection rod. While being placed on the other end, the linear body is once guided downward from the upper end of the support rod, and then folded back so as to be guided upward by the guide member. As a result, the locking lever maintains a state in which the locking lever is engaged with the weight while always being kept in a tensioned state, thereby maintaining the state in which the weight is lifted to the upper position. When the mole enters the passage, the locking lever is rotated so as not to engage with the weight, and the operation that triggers the drop of the weight is also caused by gravity from the weight. be able to . Therefore, the drive source of the mechanism that gives such an opportunity does not encounter the problem of deterioration, and can be shared with the drive source for operating the needle. Can be easy.

According to the present invention, the lower end of the support rod placed on the other end of the detection rod can be easily adjusted in response to the downward displacement of the other end of the detection rod caused by the invasion of the mole. If the detection rod is configured to be separated from the other end of the detection rod, even a slight rotation of the detection rod can be a trigger to drop the weight, so that the sensitivity of the detection rod for detecting moles can be further improved. Can be.

Further, in the present invention, if the detection rod is inclined so that one end buried in the soil is directed downward from the center of rotation, and waits for the mole, The detection rod can be more sensitively rotated by the mole entering the passage, and the mechanism that triggers the drop of the detection rod and thus the weight in the mole standby state is more stable, and malfunctions are less likely to occur. can do.

In the present invention, if an inverted U-shaped handle is provided on the upper surface of the weight, the weight can be easily lifted by grasping the handle, and after the mole has been captured, the mole is placed in a standby state. The operation for returning is facilitated. In this case, in order to prevent the weight from being accidentally dropped, a safety member that can be selectively fixed to the main body while being inserted into the handle with the weight raised to an upper position is used. With this arrangement, the operation for restoring the mole to the standby state becomes easier, and the operator can be prevented from being injured by the needle. can do.

In the present invention, if the main body is provided with a closing member that closes the lower surface of the passage, the captured moles can be prevented from escaping deeper into the soil and escaping. Can be further enhanced.
