Capturer for ecologically killing pomacea canaliculata

Abstract

A trap for ecologically killing pomacea canaliculata is composed of a cage woven by a framework with a small upper opening and a large lower opening. An inner layer of catching net, an outer layer of catching net and a plurality of vertical climbing rods which are gathered upwards are fixed in the upper end opening of the cage; the lower end of the outer-layer catching net is closed, the lower end of the inner-layer catching net is still open, and the inner-layer catching net and the outer-layer catching net are installed in a nested mode; after the inner-layer catching net and the outer-layer catching net are installed in the cavity opening in the upper end of the cage in a stacked mode, the ampullaria gigas sequentially climbs on the vertical climbing rods along the bottom of the cage under the action of the trapping lamp, then directly falls into the inner-layer catching net, and then falls into the outer-layer catching net through the inner-layer catching net to be collected. The automatic capturing efficiency is high, and no damage is caused to the environment.

Description

Technical Field

[0001] The utility model belongs to the technical field of ecological prevention and control, and specifically relates to a catcher for ecologically killing golden apple snails. Background Art

[0002] In addition to being extremely destructive to rice fields, the golden apple snail is also an intermediate host of parasitic diseases that cause jaundice in humans and animals, which can cause health problems for surrounding residents. Currently, the prevention and control of golden apple snails are usually divided into manual capture and chemical control. Manual capture requires a lot of manpower and material resources and is inefficient. Although the chemicals used in chemical control are effective, they cause great harm to the environment. Utility Model Content

[0003] The utility model aims to provide a trap for killing golden apple snails with compact structure and protection of ecological environment against damage, in view of the deficiencies in the prior art.

[0004] The utility model is realized through the following technical scheme: a trap for killing golden apple snails ecologically, which is composed of a cage woven by a skeleton with a small upper opening and a large lower opening; the utility model is characterized in that inner and outer layers of capturing nets and a plurality of vertical climbing poles gathered upward are fixed in the upper opening of the cage; the upper ends of the inner and outer layers of capturing nets are both open, the lower end of the outer layer of capturing net is closed, the lower end of the inner layer of capturing net is still open, and the inner and outer layers of capturing nets are installed in a stacked manner.

[0005] Trapping lights are fixedly arranged on the tops of the several climbing poles gathered upwards, and the climbing poles are evenly distributed at the edge of the upper port of the cage and extend upwards and gather together.

[0006] A plurality of telescopic rods supported on the ground are evenly fixed downwardly on the edge of the upper port of the cage.

[0007] The cage is constructed of skeleton materials and is cone-shaped. The cage is surrounded by horizontal climbing poles that are evenly spaced laterally.

[0008] The beneficial effect of the utility model is reflected in that, compared with the prior art, after the utility model superimposes and installs the inner and outer layers of capturing nets in the upper cavity of the cage, the golden apple snails climb up the vertical climbing pole along the bottom of the cage in turn under the action of the trapping light and then directly fall into the inner layer of capturing net, and then fall from the inner layer of capturing net into the outer layer of capturing net for collection; the automatic capturing efficiency is high and no damage is caused to the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is described in detail below in conjunction with the accompanying drawings.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0013] The utility model capture device is mainly an improvement on the shortcomings of low efficiency of current artificial capture or environmental damage caused by chemical treatment.

[0014] like Figure 1 As shown, a trap for killing golden apple snails ecologically is composed of a cage woven from a skeleton with a small upper opening and a large lower opening, both the upper and lower ends are open, the cage is directly placed in a rice field or a ditch, and the upper end of the cage is kept exposed to the water surface for good use effect; inner and outer layers of capturing nets and several vertical climbing poles 2 gathered upward are fixed in the upper end 8 of the cage, and the horizontal vertical climbing poles 2 are exposed for the golden apple snails to lay eggs on the poles, so that the eggs can be disposed of in time; the upper ends of the inner and outer layers of capturing nets are both open, the lower end of the outer layer of capturing net 5 is closed, and the lower end of the inner layer of capturing net 4 is still open, and the inner and outer layers of capturing nets are installed in a stacked manner, so that when the golden apple snail climbs onto the vertical climbing poles 2, since the golden apple snail will not return along the original path, the golden apple snail can only fall into the inner layer of capturing net 4 first, and then fall into the outer layer of capturing net 5 for collection.

[0015] A trapping lamp 1 is fixedly arranged on the top of the several vertical climbing poles 2 that gather upward, and the vertical climbing poles 2 are evenly distributed at the edge of the upper port 8 of the cage and extend upward and gather.

[0016] Three telescopic rods 3 supported on the ground are evenly fixed downward at the edge of the upper port 8 of the cage. When the water surface is deep, the telescopic rods can be extended and supported in cement to support the cage, so that the upper port 8 is exposed above the water surface and the vertical climbing rod 2 is always kept dry.

[0017] The cage is constructed of skeleton materials such as metal wire or other plastic fiber wires and is cone-shaped. The cage is evenly spaced laterally around horizontal climbing poles 7. The bottom surface of the cage is a bottom frame 6. When the level is not deep, such as used in a rice field, it is only necessary to place the bottom frame 6 in the rice field. The metal wire can be constructed into three layers, such as a bottom frame 8, a middle frame 9 and an upper frame with an upper port 8. The upper frame does not have a horizontal climbing pole, but only a vertical climbing pole 2. The lower frame and the frame are surrounded by horizontal climbing poles 7, and the horizontal climbing poles 7 are used for the golden apple snail to crawl upward.

[0018] The method of using the trap of the utility model is as follows: when used in a paddy field, the bottom frame 8 only needs to be placed directly in the paddy field. For example, in a place where the water surface of a ditch or river is deeper, the telescopic rod 3 needs to be extended and supported in the ditch or river, and the upper port 8 is always kept above the water surface. Under the action of the trapping light, the golden apple snail climbs upward along the horizontal climbing rod 7 in sequence, and then climbs to the vertical climbing rod 2 to lay eggs. After reaching the top, the golden apple snail will not return along the original path, so it can only fall into the inner capture net 4 first, and then fall into the outer capture net 5 for unified collection and treatment. Since the capture net is composed of two layers, the golden apple snail that falls into the outer capture net 5 will never climb out and escape again.

[0019] The utility model has reasonable structural design and does not require manual capture, and the purpose of catching the golden apple snails can be achieved by simply collecting them at regular intervals.
