However, due to the management of pond or paddy field production, such as pond drying, disinfection, field sunning, pesticide spraying and the like, and the change of water quality and flood peak in the river, the growth, propagation and yield of snails are greatly affected, and the yield of snails is reduced. Moreover, the snails are cultivated by means of natural conditions, and the more outstanding problem is that the snails in the cultivation area are unevenly distributed/fed due to the large area of the cultivation area and the difficult feeding of part of cultivation environments (such as rivers and paddy fields), and the snails in different positions are different in food intake, so that finally, the collected snails are inconsistent in specification, poor in quality and influence on economic benefits.

Detailed Description

The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.

Referring to fig. 1 to 5, the snail offspring seed cultivation system of the present utility model includes a feed tank 1 and a cultivation unit 3.

The feed tank 1 is used for providing a nutrient water body for the culture unit 3. The nutrient water body is mainly slurry formed by pulping soaked dry alfalfa or dry soybean and diluting with water. In order to ensure uniformity of slurry in the feeding tank 1 and to avoid precipitation of particles in the slurry, the stirrer 12 is installed in the feeding tank 1 in this embodiment, and is used for stirring the water in the feeding tank 1 during slurry adding and feeding, so that a nutrition water body with evenly distributed nutrition substances is formed, and even feeding and feeding of snails in each culture unit 3 are facilitated.

Install immersible pump 5 in the feed pond 1, the delivery pipe 6 is installed to the play water end of immersible pump 5, and inlet tube 7 is all installed to the one end of all breeding unit 3, and all inlet tubes 7 all are linked together with delivery pipe 6, and overflow pipe 22 is installed to the other end of breeding unit 3, and overflow pipe 22 is linked together with feed pond 1 through back flow 4. By the arrangement of the water inlet pipe 7, the overflow pipe 22 and the return pipe 4, a circulating water supply loop is formed between the feeding pool 1 and the cultivation unit 3.

Since the nutrient substances in the nutrient water body mainly comprise granular substances, after the nutrient water body enters the culture unit 3, the nutrient substances in the nutrient water body can be effectively precipitated, and thus the nutrient water body is ingested by the snails. As nutrients in the water of the culturing unit 3 settle and are ingested, the water in the culturing unit 3 becomes clear. The clear water body overflows from the overflow pipe, so that the loss rate of nutrient substances in the water body is reduced. As the body of water circulates between the breeding unit 3 and the feeding tank 1, the body of water in the feeding tank 1 will also become increasingly clear, and its overall transparency increases.

In order to improve the utilization rate of the snail cultivating space, the cultivating unit 3 of the present embodiment is composed of a plurality of water trays 23 stacked and installed on the bracket 21. A branch pipe 9 communicated with the water inlet pipe 7 is arranged above one end of the water disc 23, and a flow control valve 8 is arranged on the branch pipe 9. The flow control valve 8 is used to control the water inflow of the water trays 23 so that the water inflow of each water tray is consistent, thereby realizing the substantial consistency of the nutrients provided for each water tray and facilitating the uniform growth of snails. The overflow pipe 22 is mounted at the end of the water tray 23 remote from the branch pipe 9. I.e. the water inlet and outlet ends of the water tray 23 are respectively positioned at the two ends of the water tray 23, which is beneficial to the precipitation of nutrient substances.

In addition, the water tray 23 has a rectangular structure with a cross-sectional area of 4 square meters. By this arrangement, a sufficient sedimentation time is provided for the nutrients.

An evacuation tube is provided below the water tray 23. During the cultivation, the feeding can be stopped periodically, and the snail feces and food residues in the water tray 23 are cleaned and discharged through the emptying pipe.

A transparency sensor is arranged in the feeding tank 1, and the output end of the transparency sensor is electrically connected with the input end of the submersible pump 5. The transparency sensor is used to monitor the transparency of the water in the feed tank 1 and to stop the operation of the submersible pump 5 when the transparency of the water reaches the transparency sensor's operation threshold.

The transparency susceptor of this embodiment comprises a control box 11, a suspension box 10, a light source 13 and a photoresistor 14. The control box 11 is mounted outside the feed tank 1, in which an internal control circuit is mounted.

Specifically, the internal control circuit includes a transformer 18, a rectifier bridge 19, and a relay 20. The input end of the transformer 18 is electrically connected with a mains supply line, the output end of the transformer 18 is electrically connected with the input end of the rectifier bridge 19, the positive output end of the rectifier bridge 19 is connected with the light source 13 and the photoresistor 14 in parallel, the other end of the light source 13 is electrically connected with the negative output end of the rectifier bridge 19, the other end of the photoresistor 14 is electrically connected with one end of a coil of the relay 20, and the other end of the coil of the relay 20 is electrically connected with the negative output end of the rectifier bridge 19. The normally closed end of the relay 20 is connected to the power supply line of the submersible pump 5.

When the water transparency in the supply tank 1 is high, the light emitted by the light source 13 irradiates on the photoresistor 14, so that the internal resistance of the photoresistor is reduced, and the electric signal output by the rectifier bridge 19 can be transmitted to the coil of the relay 20 and triggered. The normally closed end of the relay 20 will be disconnected from the common end, powering down the submersible pump 5 and stopping operation. On the contrary, when the water transparency in the feeding pool 1 is lower, the light receiving rate of the photoresistor 14 is insufficient, so that the internal resistance of the photoresistor is increased, and the electric energy obtained by the coil of the relay 20 is insufficient to trigger the photoresistor, so that the normally-closed end of the relay 20 is connected and conducted with the public end, and the submersible pump 5 is electrified to work.

A suspension tank 10 is installed in the supply tank 1. The suspension tank 10 is composed of an upper seal tank 15, a lower seal tank 17 and a fixing rod 16. The upper sealing box 15 is fixedly connected with the lower sealing box 17 through a fixing rod 16, the light source 13 is arranged in the upper sealing box 15, the photoresistor 14 is arranged in the lower sealing box 17, and the opposite sides of the upper sealing box 15 and the lower sealing box 17 are of transparent structures. The light source 13 corresponds to the installation position box of the photoresistor 14, so that the light energy emitted by the light source irradiates on the photoresistor 14.

A weight is installed in the lower seal box 17 for controlling the levitation position of the levitation box 10 and keeping the upper seal box 15 of the levitation box 10 always above the lower seal box 17 thereof.

The working principle of the utility model is as follows: the stirrer 12 is started, then slurry is added into the feed tank 1, and the water in the feed tank 1 is formed into a nutrient water body through the stirring action of the stirrer 12. The internal control circuit is powered up and the suspension tank 10 is placed in the feed tank 1. Because the transparency of the water in the feeding pool 1 is low at this time, the relay 20 does not act, so that the submersible pump 5 is powered on to deliver the nutrient water to each water tray 23. The water supply amount of each water tray 23 is uniform by the flow control valve 8 on the branch pipe 9. After the water in the water tray 23 overflows, the water overflows through the overflow pipe 22 and flows back to the feeding tank 1 through the return pipe. The water transparency in the feeding pool 1 is increased, and when the light irradiated by the light source 13 on the photoresistor 14 makes the internal resistance of the photoresistor 14 lower than a certain preset resistance value, the coil of the relay 20 obtains enough electric energy, so that the relay 20 acts, the normally closed end of the relay is disconnected from the public end, and the submersible pump 5 is powered off to stop working. At this time, the staff can add the slurry again to continue feeding the snails.

While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
