TECHNICAL FIELD

[0001] The utility model relates to a fertile shrimp processing technical field, concretely relates to a fertile shrimp hatching collection device. BACKGROUND

[0002] Fertile shrimps are rich in protein, unsaturated fatty acids (such as DHA and EPA) and other nutrients, and are ideal opening feed for many aquatic animal larvae (such as fry, shrimp fry, crab fry, etc.) and small ornamental fish larvae. The newly hatched fertile shrimp nauplii are small in size, slow in swimming, easy to be preyed on by larvae, and rich in nutrients, which can meet the needs of rapid growth and development of larvae. If hatching and collection are not carried out, such high-quality fresh feed cannot be obtained, and the growth and survival rate of aquatic animal larvae may be affected.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] It should be noted that the main concept of this utility model is that by setting up a pH meter 5 and a heating component, the controller can obtain real-time information on the pH and temperature environment inside the chamber 1, thereby determining the amount of shrimp, water, salt, and alkali to be added to the chamber 1. This allows the brine shrimp to hatch quickly under suitable pH, salinity, and temperature conditions, improving hatching efficiency. Compared with the prior art, this device can effectively monitor various environmental parameters inside the chamber 1 in real time and make effective and rapid adjustments to fully meet the hatching requirements of brine shrimp.

[0026] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0027] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0028] Example 1 of the brine shrimp hatching and collection device provided by this utility model:

[0029] like Figures 1 to 5 As shown, the brine shrimp hatching and collection device includes a box 1, a filter tank 2, and a wastewater tank 3 connected sequentially from top to bottom. The box 1 is used to hatch brine shrimp. The filter tank 2 has a filter plate 4 inside. The wastewater tank 3 has an outlet 13 at the bottom and an inlet at the top of the box 1. The box 1 has a pH meter 5 and a temperature sensor 15 inside. A heating component that extends into the box 1 is also installed on the box 1. The side wall of the box 1 has a shrimp inlet 6, a salt inlet 7, and an alkali inlet 8. The shrimp inlet 6 is connected to a shrimp storage device through a shrimp inlet pipe. The salt inlet 7 is connected to a salt storage device through a salt inlet pipe. The alkali inlet 8 is connected to an alkali storage device through an alkali inlet pipe. The box 1 also has an openable partition 9 to separate or connect the box 1 and the filter tank 2.

[0030] The entire device also includes a controller that connects the pH meter 5, heating components, shrimp storage equipment, salt storage equipment, and alkali storage equipment. The controller is used to control each device to add shrimp, water, salt, and alkali into the tank 1.

[0031] It should be noted that whether adding salt or alkali, the liquid salt and alkali solutions are added to tank 1 through pipelines. Therefore, the salt and alkali content can be adjusted via the salt inlet and alkali inlet pipes. The alkali storage equipment and salt storage equipment are not shown in the diagram; corresponding pumps are installed on the salt inlet and alkali inlet pipes to provide power, and the pumps are controlled by a controller. The same applies to adding shrimp.

[0032] like Figures 1 to 4As shown, the water inlet is provided with a water inlet pipe 14, which is located at the upper end side of the box 1, and has a water distribution structure at the end thereof towards the inside of the box 1 for expanding the spraying range of the water flow. In the initial stage, the water inlet pipe 14 starts to supply water after the shrimp, salt and alkali are added into the box 1, and due to the expanded spraying range, the water flow can quickly contact and mix with the shrimp, salt and alkali far away from the water inlet.

[0033] Specifically, referring to Figure 3 and Figure 4 , the water distribution structure is a plurality of tapered protrusions 10 arranged at the inner periphery of the water inlet pipe 14, the tips of the tapered protrusions 10 are towards the center of the water inlet pipe 14, and the plurality of tapered protrusions 10 are evenly distributed along the inner periphery of the water inlet pipe 14.

[0034] As shown in Figure 2 , the heating assembly is a plurality of heating rods 11.

[0035] As for the installation of the partition plate 9, it can be referred to Figure 2 and Figure 5 , the partition plate 9 is rotatably installed at the lower end of the box 1, the filter tank 2 is provided with an extension mechanism connected to the lower end of the box 1 and arranged obliquely, and the output end of the extension mechanism is supported at the lower end of the partition plate 9 to control the downward opening or upward blocking of the partition plate 9 by extension. In this embodiment, the extension mechanism is a gas spring 12.

[0036] In this embodiment, the box 1, the filter tank 2 and the wastewater tank 3 are connected by bolts, and the output end of the extension mechanism is detachably connected to the lower end of the partition plate 9. In this way, the entire device can be easily disassembled.

[0037] The working principle of the hatching and collecting device for the Plippe shrimp provided by the utility model is that the controller is used to control the addition of shrimp, water, salt and alkali into the box 1, and the values of the pH detector 5 and the temperature sensor 15 are used to adjust the parameters in real time, so that the Plippe shrimp can be quickly hatched. After the hatching is completed, the gas spring 12 drives the partition plate 9 to move downward, and the mixture of shrimp, shrimp shells and dead eggs enters the filter tank 2 for filtration, and the shrimp shells and dead eggs are removed.

[0038] Embodiment 2 of the hatching and collecting device for the Plippe shrimp provided by the utility model is as follows:

[0039] The difference between the embodiment 2 and the embodiment 1 is mainly as follows:

[0040] In the embodiment 1, the water distribution structure is a plurality of tapered protrusions arranged at the inner periphery of the water inlet pipe, the tips of the tapered protrusions are towards the center of the water inlet pipe, and the plurality of tapered protrusions are evenly distributed along the inner periphery of the water inlet pipe.

[0041] In the embodiment, the conical protrusion can also be changed into a spiral protrusion.

[0042] The embodiment 3 of the hatching and collecting device for abundant-year shrimps provided by the utility model has the advantages of simple structure, convenient use, high efficiency, and low cost.

[0043] The difference between the embodiment and the embodiment 1 mainly lies in that:

[0044] In the embodiment 1, the telescopic mechanism is a gas spring.

[0045] In the embodiment, the telescopic mechanism is a hydraulic cylinder.

[0046] According to the above description of the present specification, those skilled in the art can also understand that the terms used such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer" and the like indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present specification, and are only for the purpose of facilitating the description of the scheme of the utility model and simplifying the description, and do not explicitly or implicitly indicate or suggest that the devices or elements involved must have the specific orientation, be constructed and operated in the specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the scheme of the utility model.

[0047] In addition, in the description of the present specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise explicitly and specifically limited.
