Description

Device for inducing ampullaria gigas to spawn and auxiliary cleaning mechanism thereof

Technical Field

The utility model relates to the technical field of ampullaria gigas egg removal, in particular to a device for inducing ampullaria gigas to lay eggs and an auxiliary cleaning mechanism thereof.

Background

The ampullaria gigas seriously jeopardizes crop production. At present, the normal growth of the ampullaria gigas is limited, and the number of the ampullaria gigas can be well limited by inducing the ampullaria gigas to spawn and collecting and destroying eggs.

The ampullaria gigas usually spawns at a height of between 11 and 35cm from the water surface, and the spawning location is fixed. Therefore, related personnel provide a mode of inducing the ampullaria gigas to spawn by inserting the upright posts, and experiments prove that the ampullaria gigas has a good effect.

However, in practical application, the company finds that a mode of adopting a single upright rod is effective, but is not good enough, and a plurality of ampullaria gigas lay eggs on Dan Kanbi and canal walls of the pond; based on the situation, a new device for trapping the ampullaria gigas to lay eggs is designed to improve the induction effect and the cleaning effect of the eggs from the device.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, provide a device for inducing ampullaria gigas to spawn and an auxiliary cleaning mechanism thereof, and solve the problem that a single upright rod is insufficient in spawning inducing ampullaria gigas.

It should be noted that the mode of a single upright rod is mainly that the area is too small to be found by the ampullaria gigas. The present utility model thus increases the trapping effect by increasing the area.

The aim of the utility model is achieved by the following technical scheme:

(first aspect) an apparatus for inducing ampullaria gigas to spawn comprising: the bracket is inserted into an environment with water and can stretch in the height direction; the induction net is connected to the bracket; when the bracket is unfolded, the induction net is stretched tightly, so that a crawling wall structure is formed.

As the preferable technical scheme of the application, the bracket is a plurality of aluminum vertical rods, and the induction net is unfolded after the aluminum vertical rods are alternately arranged; the lower end of the aluminum upright rod is provided with a solid tip, so that a structure which is beneficial to being inserted into water environment is formed.

As a preferable technical scheme of the application, the aluminum upright rod comprises a plurality of pipe sections A and a plurality of pipe sections B; the diameter of the pipe joint A is larger than that of the pipe joint B, and the pipe joint A and the pipe joint B are mutually inserted and locked through a round spring pin to form a telescopic structure.

As the preferable technical scheme of the application, the lower part of the induction net is weaved more densely than the upper part, so that a structure which is beneficial to the upward crawling of the ampullaria gigas is formed.

As the preferred technical scheme of this application, the induction net overlaps in aluminium system pole setting through a plurality of magnetic conduction lantern rings, and the magnetic stripe is equipped with in the aluminium system pole setting, and the magnetic conduction lantern ring is fixed through the magnetic stripe absorption.

As the preferable technical scheme of the application, the upper end of the aluminum upright rod is sleeved with a sleeve plug; the sleeve plug of the aluminum upright rod at the outermost side of the support is provided with a binding rope, and the corresponding magnetic conduction lantern ring is fixed by the binding rope to form a forced fixing structure.

As the preferred technical scheme of this application, on the support, still have the stay cord on the sleeve plug of its outside aluminium system pole setting.

(second aspect) an auxiliary cleaning mechanism of a device for inducing ampullaria gigas to spawn, comprising a shear rest and a semicircular ring; the scissors frame is in a scissors structure shape formed by hinging two rods, two semicircular rings are respectively arranged at the two cutting edge positions of the scissors frame, and the two semicircular rings are combined to form a circular ring; the semicircular ring is arranged on the shear rest through a screw rod and a spring; when the two semicircular hoops slide downwards on the aluminum vertical rod from bottom to top, the ampullaria gigas eggs on the aluminum vertical rod are removed and crushed.

The working principle of the utility model is as follows: the core principle is that the induction net is stretched and spread through a plurality of aluminum upright rods to form a climbing structure similar to a canal wall/wall, and the ampullaria gigas is induced to climb up to spawn, and the induction effect is good because the area is large enough and stable enough; in addition, the magnetic conduction lantern ring of the induction net barrel and the fixing mode of the corresponding magnetic strips are beneficial to taking down the induction net, and eggs can be killed by immersing the induction net with the ampullaria gigas eggs in water for more than 2 days; when the magnetic conduction lantern ring is taken down, one layer of eggs are scraped off, and then the eggs are completely scraped by an auxiliary cleaning mechanism.

The utility model has the following advantages:

(1) The effect of inducing the ampullaria gigas to spawn is good;

it should be noted that, the ampullaria gigas eggs cannot be soaked in water for a long time (2 days cannot be exceeded), otherwise, the eggs cannot be hatched and developed normally; the ampullaria gigas themselves live in water, so that when the ampullaria gigas spawn, plant stems or candelabra and the like with good stability are usually found, and spawning is carried out at a position 15-35 cm away from the water surface;

the current better treatment mode is to wash the eggs of the ampullaria gigas out by using a high-pressure water gun to drop the eggs into water, but the cost of the mode is too high; there are also a plurality of vertical rods inserted into a pond or the like to induce the ampullaria gigas to climb up to spawn, but the area of the vertical rods is too small, the probability of the ampullaria gigas climbing up is small, and although the effect is effective, the effect is not particularly obvious;

in the utility model, the induction net is tightened by adopting a plurality of upright rods to form a stable crawling wall structure, thus being very easy to induce the ampullaria gigas to climb up to spawn and having good induction effect; and does not hinder the normal growth of plants;

(2) The inducing device is convenient to arrange, and the ampullaria gigas eggs on the inducing device are very convenient to clean;

the induction net can be installed by sleeving the magnetic lantern ring on the aluminum upright rod, and then fixing the outermost magnetic lantern ring at the uppermost end through the binding rope; the inducing device can be arranged in ponds, paddy fields and the like through the solid pointed heads; the pull rope is guided to the side of the pond;

when cleaning, the induction device is pulled up by artificial water drainage, and the induction device can be pulled up directly by a pull rope (people do not need to drain water) (even if eggs fall into water, eggs can be killed); placing the induction device in a water basin with a large size, filling water in the water basin, unwinding two binding ropes, removing the magnetic lantern ring from the aluminum upright rod, scraping the ampullaria gigas eggs on the aluminum upright rod into the water basin when the magnetic lantern ring is taken down, and scraping one side by using an auxiliary cleaning mechanism; when the induction net is taken down, the induction net with the ampullaria gigas eggs is soaked in the basin; after soaking for 2 days, the ampullaria gigas eggs cannot normally hatch;

(3) The structure is simple, the cost is low, and the practical application is easy;

at present, no ampullaria gigas egg induction device exists in the market; while the existing patent documents have complex structures, can be used for experiments (high cost, and can not be placed in a rice field in a large scale, which can affect the normal growth of plants), the existing patent documents can not be placed in ponds and rice fields in a large scale;

the structure of the utility model is very simple, is beneficial to being placed in a large batch of rice fields, and can not influence the normal growth of plants; and can be repeatedly recycled.
