Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and particularly relates to a snail induction device and a using method thereof. Background Art

[0002] In the natural environment, snails like to forage at night or in the early morning, and drill into the mud bottom during the day, at high temperatures, or when the water level of the environment drops. However, during the breeding process of snails in paddy fields and ponds, it is found that snails like to gather at the water inlet. When the water level of the living water area slowly drops and the water gradually drains away, and new water is continuously injected into the water inlet with a large water flow sound, the snails will swim upstream under the stress of low dissolved oxygen and slowly crawl towards the water inlet to gather. Generally, snails are good at hiding and are small in size, which brings difficulties to the work of collecting snails in the breeding work of ponds and paddy fields.

[0003] At present, after the snails are cultured, they can only be collected by the traditional method of people going into the field to search and detect. In the rice planting area, snails like to attach to the roots of rice plants, which makes it more difficult for people to find them during the collection process, resulting in low snail collection rate and low work efficiency. Moreover, the traditional method is to search and pick out in each corner by manual going into the field. Once the water becomes turbid or is blocked by aquatic plants, it is very difficult to see the distribution of snails, and the collection will become more difficult, requiring more manual energy and time, which will increase the labor input cost. At present, there is no special device that can solve the above problems and is suitable for inducing and collecting snails in paddy fields or ponds. Therefore, it is crucial to study a special device for inducing snails in paddy fields or ponds. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figure 1 The snail induction device shown includes: a drainage water pipe 3, a bursting pipe clamp 5, a water-following tee 2 and a first plug 6, one end of the drainage water pipe 3 is provided with the first plug 6, and the other end is a water inlet end, the bursting pipe clamp 5 is installed on the outer wall of the drainage water pipe 3, the water-following tee 2 is installed at the water inlet end of the drainage water pipe 3, the first connecting end and the second connecting end of the water-following tee 2 are respectively connected to the drainage water pipe 3, wherein the drainage water pipe 3 at each connecting end is connected and extended by a 75 joint 12; a plurality of induced water outlets 4 are opened on the drainage water pipe 3 along the length direction.

[0035] The drainage pipe 3 is a Liansu PVC 75 pipe, which ensures that the water is drained to the destination. The induced water outlet 4 is a small hole on the Liansu PVC 75 pipe, so that the drained water flows out from here. The first plug 6 is a 75 plug, which is used to plug the tail of the drainage pipe 3 to ensure that the tail of the drainage pipe 3 does not leak and is convenient for inspection. The bursting pipe clamp 5 is used to fix the drainage pipe 3 on the ridge of the field to ensure that the position of the drainage pipe 3 is fixed and the pipe itself does not rotate.

[0036] like Figure 2 As shown, the drainage water pipe 3 is obliquely installed on the wall of the field ridge 15 by pulling the burst pipe clamp 5, and the end of the drainage water pipe close to the first plug is lower than the water inlet end of the drainage water pipe. Furthermore, the water inlet end of the drainage water pipe is 30 cm away from the bottom of the mud, and the end close to the first plug is 20 cm away from the bottom of the mud, while ensuring that the distance between the drainage water pipe 3 and the wall of the field ridge 15 is 4 to 5 cm. Through this technical solution, a water level difference can be formed inside the drainage water pipe 3, which facilitates the drainage of water. In addition, as Figure 3As shown, when the drainage pipe 3 is installed on the wall of the field ridge, the induction water outlet 4 is oriented toward the side of the breeding ground 16, so that the water can form a parabola due to the water pressure when it flows out, and form a large water sound when it falls to the water surface of the breeding ground. The water sound, water flow and high-oxygen water flow are used to induce the snails to gather at the induction water outlet 4.

[0037] Furthermore, the spacing between the burst pipe clamps 5 is 150 cm to 200 cm. Through this technical solution, the drainage pipe 3 can be installed on the wall of the field ridge 15 more stably.

[0038] The device also includes a water inlet pipe head 9 and / or a water inlet pipe 13 and a second plug 14, such as Figure 4 As shown, the water inlet pipe head 9, the water inlet pipe 13 and the second plug 14 can be detachably installed on the third connecting end of the water tee 2 through the reducer 11. Through this technical solution, the water inlet end of the drainage water pipe 3 can be filled with water in two ways, one is to use the water inlet pipe head 9, specifically the Liansu PVC 90° elbow, through which the water inlet height of the elbow can be rotatably adjusted to facilitate water inlet; the other is to use the water inlet pipe 13 to fill water, specifically, the water inlet pipe 13 is a 110 pipe, through which water is directly filled or connected to a water pipe belt, etc.; when the device is not used normally, the water inlet end of the drainage water pipe 3 is blocked with the second plug to prevent impurities from entering, and further, the second plug is a 110 plug.

[0039] The reducing direct 11 is changed from 75 to 110, and the third end of the downstream tee 2 is connected to the 110 joint 10 through the reducing direct 11. The 110 joint 10 can ensure the conversion, connection and closure of various water inlet pipes at the water inlet end of the drainage water pipe 3. The 75 end is connected to the downstream tee 2, and the 110 end is connected to the 110 joint 10. The reducing direct 11 has a large diameter water inlet and a small diameter water outlet. The large water inlet area can relieve the pressure of the water inlet and increase the water inlet area.

[0040] The water inlet pipe head 9 and / or the water inlet pipe 13 are provided with a filter screen 7. Furthermore, the filter screen 7 is a 20-mesh mesh, and a cable tie 8 can be used to fasten the filter screen 7 to the water inlet pipe head 9 and / or the water inlet pipe 13. Through this technical solution, wild fish and their eggs and larger granular impurities in the water can be filtered to prevent them from entering the drainage water pipe 3 and causing the induced water outlet 4 to be blocked.

[0041] The diameter of the induced water outlet is 0.8 cm, and the distance between two adjacent induced water outlets is 150 cm. Through this technical solution, it is possible to ensure that the snails gather at the induced water outlet.

[0042] The snail induction device disclosed in this embodiment can provide a safe, controllable, convenient induction, collection, and reusable induction facility for snail seedlings, saving snail collection process and time; the drainage pipe size, the spacing and hole size of the induction water outlet, the inclination of the drainage pipe, the fixing method of the drainage pipe, the size of the water inlet pipe head 9 and / or the water inlet pipe 13, and the different diameter direct size of the snail induction device of the present invention are not limited to the technical content of this embodiment. The operator can adjust and formulate the size of the water inlet pipe head 9 and / or the water inlet pipe 13, the length and size of the drainage pipe, the spacing and hole size of the induction water outlet, and the method, height and inclination of fixing the drainage pipe according to the size of the field, the type and specification of the snail, so as to induce snails in different snail breeding sites and create convenient collection conditions. The snail induction device is simple in material, convenient in operation, strong in practicality, high in safety, and has broad application prospects.

[0043] Example 2

[0044] The method for using the snail induction device described in Example 1 comprises the following steps:

[0045] Step 1: Install the first plug 6 at one end of the drainage water pipe 3, install the water inlet end of the drainage water pipe 3 on the water tee 2, install the 110 joint 10 on the third end of the water tee 2 through the reducer 11, then install the water inlet pipe head 9 on the 110 joint 10, and tie the filter 7 to the water inlet pipe head 9 with a cable tie 8;

[0046] The drainage pipe 3 is installed obliquely on the inner wall of the ridge 15 of the breeding ground 16, and the end of the drainage pipe 3 close to the first plug 6 is kept lower than the water inlet end of the drainage pipe 3, and the induced water outlet 4 is arranged toward the breeding ground 16;

[0047] Step 2: After introducing new water into the breeding ground 16, open the field water outlet 17 of the breeding ground 16 to release water. The field water outlet 17 is protected with a 20-mesh anti-escape mesh to prevent the snails from escaping, and water enters the drainage water pipe 3 through the water inlet end of the drainage water pipe 3; the field water outlet 17 releases water to form hypoxia stress, and the drainage water pipe 3 inlets water to form a high dissolved oxygen environment at the induced water outlet. Through the sound of water flow, the direction of water flow and the high dissolved oxygen brought by water, the snails are induced to crawl to the induced water outlet 4. The snails crawl slowly. It is best to release water in 4-6 hours per acre of breeding water area, and the effect of releasing water at night is better than that during the day; when the snails are induced to concentrate at the induced water outlet 4, pick out the snails at each induced water outlet 4 in turn;

[0048] Step 3: After picking up the field snails at each induced water outlet 4, block the field outlet 17, open the field inlet 18 of the breeding site 16. After 6 - 12 hours when the breeding site 16 is filled with water, the snails that burrowed into the mud climb out again. Then open the field outlet 17 to drain water, keep the induced water outlet 4 open, induce the snails to gather at the induced water outlet 4, and then block the field outlet 17 again to pick up the snails.

[0049] Repeat the induction - snail picking process above 2 - 3 times to achieve the purpose of facilitating the collection of field snails.

[0050] Example 3

[0051] Based on the method of using the field snail induction device described in Example 2, the breeding site 16 is square, and the field outlet 17 and the field inlet 18 are arranged at one pair of diagonal points of the square breeding site 16. The method of use further includes the following steps:

[0052] As Figures 5 - 6 shown, arrange two sets of the field snail induction devices described in Example 1 along the diagonals of the square breeding site 16 respectively, and arrange two water - flow - through tees 2 at the other pair of diagonal points of the breeding site 16. Drainage pipes 3 are arranged along the four sides of the breeding site 16. Among them, the water inlet head 9 is installed outside the field ridge to facilitate water inlet and adjustment of the pipe head direction. Such an arrangement can ensure that the field snails in the breeding site 16 are collected comprehensively and improve the collection rate.

[0053] Although the present invention has been described in detail with general descriptions and specific examples above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
