Description

  The present invention relates to an animal sorting device, a lure prevention fence, an overpass prevention fence, and a movement prevention fence for the purpose of preventing crop damage from wild animals such as deer and sharks.

  Wild animals that inhabit mountain forests, such as deer (first target animal) and moth (second target animal), descend from the mountains to the hills, causing crop damage that eats and destroys the crops in the field. As a countermeasure, there is known a boarding prevention fence that partitions a field and an area around the field and prevents wild animals from entering the field (for example, see Patent Document 1). In this method, the field is surrounded by a fence to prevent entry into the field.

  A method of arranging such a fence in the mountains is also known (see, for example, Patent Document 2). Such a boarding prevention fence is installed so as to partition a village where the field is located (first region) and a wildlife habitat, for example, a forest (second region). This boarding fence has a pole (pillar) at the boundary between the village and the forest, and a net is attached to the pole that is higher than the height at which wild animals can get over. Since such a boarding prevention fence is arrange | positioned upwards from the ground, it functions not only as a boarding prevention but as a movement prevention fence which prevents the movement from a forest to an isolat.

  By the way, wild animals that inhabit mountain forests are herbivorous or omnivorous and sometimes eat tree epidermis as food. For this reason, if the number of wild animals in the forest increases, trees may be damaged by food, causing serious damage to forestry. However, if the number of individuals decreases due to extermination of wild animals, for example, the balance between the number of foxes and deer will be lost, which may destroy the forest ecosystem. As a countermeasure against such a problem, a wild animal capturing device is attached to the above-described overpass prevention fence. The number of individuals is adjusted by exterminating the captured wild animals or returning them to the forest.

  The above-mentioned boarding prevention fence has the following problems. That is, the wild animals include a plurality of types of animals such as frogs and deer. Since the spider has the property of digging a hole in the ground with its nose, it may dig into the hole under the overpass prevention fence. In addition, the heel may widen the gap of the net at the nose, break the net, and pass through the hole that widens the gap. From this hole, not only a shark but also a deer may pass through. Therefore, there is a possibility that functions as a boarding prevention fence and a movement prevention fence cannot be sufficiently exhibited.

  Furthermore, in order to maintain the ecosystem, it is necessary to maintain a balance between the number of foxes and deer. For this reason, moths and deer must be adjusted separately. However, both the shark and the deer are captured together in the capture part of the above-mentioned overpass prevention fence. In this case, after catching, it is necessary to sort out spiders and deer. During this work, the spider and deer are excited and rampaged by facing humans and may attack humans. For this reason, the sorting operation after capture is difficult and has a problem with danger.

The guide path 70 has a function of guiding the eaves B and the deer D to the first sorting unit 80 and the second sorting unit 90 side by a passage surrounded by the wall mesh unit 73 and the floor mesh unit 74.

  As shown in FIG. 5, a first sorting unit 80 is provided at the end of the guide path 70 on the opposite side to the guide fence 10. The first sorting unit 80 includes a first fence-like part 81 surrounding the first sorting area F4 that is a part of the isolator F1, and the guide path 70 and the first sorting area F4 of the first fence-like part 81. And a first inlet 82 formed therebetween. The first inlet 82 is provided with a first door 84 that can be opened only to the first sorting region F4 side and is biased in the closing direction. As shown in FIG. 7, the first inlet 82 is further provided with a first blocking portion 83. In the first selection area F4, bait E targeting moth B and deer D is arranged.

  The first blocking portion 83 is disposed above the first inlet 82 from a third height H3 that is a predetermined height. The third height H3 is a height at which the ridge B can pass through the lower side and the deer D cannot pass through the lower side.

  Since the body height differs between the heel B and the deer D, as shown in FIG. 8, the minimum value of the through-hole height that can penetrate under the obstacle is different as shown in FIG. That is, the minimum value of the through-hole height of the rod B is the first through-hole height TH1, and the minimum value of the through-hole height of the deer D is the second through-hole height higher than the first through-hole height TH1. TH2. The relationship between the third height H3 at which the lower end portion of the first blocking portion 83 is located, the first through-hole height TH1, and the second through-hole height TH2 is TH1 <H3 <TH2.

  The 2nd interruption | blocking part 93 is arrange | positioned in the range from the ground of the 2nd entrance 92 to 4th height H4 which is predetermined | prescribed height. The fourth height H4 indicates a height at which the deer D can get over the upper side and the ridge B cannot get over the upper side.

  Since the body height is different between the heel B and the deer D, as shown in FIG. 10, the maximum value of the overpass height that can be passed over the obstacle is different. That is, the maximum value of the overpass height of the heel B is the first overpass height NH1, and the maximum value of the overpass height of the deer D is the second overpass height NH2 higher than the first overpass height NH1. The relationship between the fourth height H4 at which the upper end of the second blocking portion 93 is located, the first overpass height NH1, and the second overpass height NH2 is NH1 <H4 <NH2.

  The wild animal sorting and capturing apparatus 1 according to one embodiment of the present invention described above functions as follows.

  In the movement prevention fence 20, the 1st color part 33a and the 2nd color part 33b are provided along the boundary part F3. Since the color of the second color part 33b is for moth B and deer D and has distinctiveness with respect to the color of the first color part 33a, moth B and deer D are present in the movement prevention fence 20. Can be recognized.

  When recognizing the presence of the movement prevention fence 20, the eaves B and the deer D do not attempt to penetrate the movement prevention fence 20 and move to the left or right toward the movement prevention fence 20. In the present embodiment, bait E is provided in the first sorting area F4 and the second sorting area F5 of the sorting device 60. For this reason, it is induced by the smell of the bait E and moves to the sorting device 60 side. Furthermore, since the first color portion 33a and the second color portion 33b are provided along the boundary portion F3, it is possible to guide the basket B and the deer D to the sorting device 60 along the boundary portion F3.

  Further, the movement prevention fence 20 is provided with a fine mesh portion 31 having a gap 32. When the mesh gap is large, the heel B pierces the nose BN into the mesh gap and destroys the mesh. However, since the cross-sectional area of the gap 32 of the fine mesh part 31 is smaller than the cross-sectional area of the nose part BN, the nose part BN is not pierced into the gap 32 and the movement prevention fence 20 can be prevented from being damaged.

  In the boarding prevention fence 40, the height of the first wire 42 is the height of the upper arm portion BLd of the heel B. As a result, it is difficult for the kite B to get over the first wire, so that the movement prevention fence 20 is prevented from being damaged and guided to the sorting device 60.

  Further, the undercut prevention unit 50 prevents the undercarriage of the kite B below the movement prevention fence 20. That is, the ridge B has a property of digging a hole in the nose portion BN, but in the present embodiment, by providing the undercut prevention portion 50, it is possible to prevent the hole from being dug and passing under the movement prevention fence 20. it can.

  The shark B and the deer D guided by the guide fence 10 are further guided into the sorting device 60 from the animal introduction port 11. The shark B and the deer D guided into the sorting device 60 move along the guide path 70 toward the first sorting area F4 and the second sorting area F5.

  Since the first blocking part 83 through which only the basket B can pass is provided at the entrance of the first sorting area F4, only the basket B is guided to the first sorting area F4. On the other hand, since the entrance of the second sorting area F5 is provided with the second blocking portion 93 that allows only the deer D to get over, only the deer D is guided to the second sorting area F5.

  A first door 84 and a second door 94 are provided at the first inlet 82 and the second inlet 92, respectively. The frog B and the deer D can push the obstacle, but cannot pull it. For this reason, the moth B and the deer D that are guided to the first selection area F4 and the second selection area F5, respectively, cannot leave the first selection area F4 and the second selection area F5.

  Thereby, the sorting device 60 can sort and capture the basket B in the first sorting area F4 and the deer D in the second sorting area F5.

  Thus, according to the wild animal sorting and capturing device 1 according to the present embodiment, the guide fence 10 prevents the shark B and the deer D from moving to the village F1, and guides them to the sorting device 60. It is possible to select and capture shark B and deer D. Thereby, the damage to the crop of the field P by the fence B and the deer D can be prevented.

As described above, according to the present invention, it is possible to easily select a plurality of types of target animals while preventing invasion from the second region into the first region. The form is not limited. For example, in the above-described example, the first color portion and the second color portion are white and green, respectively. However, this is a case where this is a combination of other colors having distinctiveness targeting moths and deers. Of course, the same applies. Of course, various modifications can be made without departing from the scope of the present invention.
