The terms "installed", "one end", "the other end" and similar expressions used in this utility model are for illustrative purposes only.

[0030] This embodiment provides a device for hatching Artemia, such as Figure 1-4 As shown, it includes an incubator 1, which is provided with a gas explosion pipe 2 and a filtering device; the output end of the gas explosion pipe 2 is arranged opposite to the top of the incubator 1, and the filtering device is arranged above the gas explosion pipe 2, and the filtering device is provided with a filter channel 31 with an adjustable size. The filter channel 31 has an adjustable size, so that the size of the filter channel 31 can be adjusted according to the volume of the egg shell, so that egg shells of different volumes can pass through the filtering device, and the egg shells and the Artemia larvae are completely separated.

[0031] The filtering device includes a filter screen 3 and an adjustment component 4. A filtering channel 31 is provided along the filtering direction of the filter screen 3. The filtering channel 31 is provided corresponding to the filter holes of the filter screen 3. The adjustment component 4 is provided in the filtering channel 31. The adjustment component 4 is provided with more than two movably arranged dividing pieces. The dividing pieces are used to divide the filtering channel 31. The passing area of ​​the filtering channel 31 is adjusted by changing the number of projections of the dividing pieces in the filtering channel 31.

[0032] In this embodiment, the adjustment component 4 includes more than two adjustment parts, the filter 3 and the adjacent adjustment parts are stacked along the height direction of the incubator 1, and a first bracket 11 and a second bracket 12 are provided in the incubator 1. The filter 3 is placed on the first bracket 11, and the number of the second brackets 12 corresponds to the number of the adjustment parts. The adjustment parts are placed on the second bracket 12, and a ball is provided on the second bracket 12. The adjustment parts are movably connected to the second bracket 12.

[0033] In a preferred embodiment, the first bracket 11 and the second bracket 12 are detachably arranged in the incubator 1; the detachable first bracket 11 and the second bracket 12 are arranged to facilitate the installation of the filter 3 and the adjustment component; during installation, the first bracket 11 is installed first, and then the filter is placed on the first bracket 11; then a second bracket 12 is installed, and an adjustment component is placed on the second bracket 12; and then the remaining second brackets 12 and adjustment components are installed upward in the height direction. This makes it convenient to clean the incubator. During disassembly, first take out the topmost adjusting piece, and then remove the second bracket 12 corresponding to the adjusting piece; then remove the remaining adjusting pieces, the second bracket 12, the filter screen 3 and the first bracket 11 in turn from top to bottom along the height direction. Each adjusting piece is provided with one or more dividing pieces, which divide the filter channel 31; the dividing piece is located in the filter channel 31, and the filter channel 31 is blocked by the dividing piece, so that the passing area of ​​the filter channel 31 is reduced. When filtering small-volume eggshells, the passing area of ​​the filter channel 31 is reduced, and by increasing the number of projections of the dividing piece in the filter channel 31, a dividing piece is rotated to the top of the filter channel 31, and the filter channel 31 is divided for the first time; thereby reducing the passing area of ​​the filter channel 31; when it is necessary to continue to reduce the passing area of ​​the filter channel 31, another dividing piece with a different horizontal height is rotated to the top of the filter channel 31 and is staggered with one dividing piece, and the other dividing piece divides the filter channel 31 after the first division for the second time; in this way, the passing area of ​​the filter channel 31 can be reduced twice.

[0034] When filtering large-volume egg shells, the passing area of ​​the filter channel 31 is increased by reducing the number of projections of the partition in the filter channel 31, rotating a partition located above the filter channel 31, and overlapping one partition with another partition at a different horizontal height, so that one partition no longer blocks the filter channel 31, thereby increasing the passing area of ​​the filter channel 31.

[0035] Specifically, Figure 2 As shown, there are four adjusting members, namely a first adjusting member 41, a second adjusting member 42, a third adjusting member 43 and a fourth adjusting member 44; the first adjusting member 41 is provided with three first dividing members 411, the second adjusting member 42 is provided with three second dividing members 421, the third adjusting member 43 is provided with three third dividing members 431, and the fourth adjusting member 44 is provided with three fourth dividing members 441.

[0036] When filtering small egg shells, the passing area of ​​the filter channel 31 is reduced, referring to Figure 4 As shown in A, the first partition 411, the second partition 421, the third partition 431 and the fourth partition 441 are staggered, and at this time, the passing area of ​​the filter channel 31 is the smallest.

[0037] When filtering large egg shells, increase the passing area of ​​the filter channel 31, refer to Figure 4 As shown in B, the third adjusting member 43 and the fourth adjusting member 44 are rotated so that they overlap with the second adjusting member 42, and the third dividing member 431 and the fourth dividing member 441 are moved below the second dividing member 421; the number of projections of the dividing members in the filter channel 31 is reduced, so that the passing area of ​​the filter channel 31 is increased.

[0038] In a preferred embodiment, the first adjusting member 41 , the second adjusting member 42 , the third adjusting member 43 and the fourth adjusting member 44 are manually driven to rotate.

[0039] In another preferred embodiment, a driving device 5 is provided, and the driving device 5 is connected to the first adjusting member 41, the second adjusting member 42, the third adjusting member 43, and the fourth adjusting member 44 respectively through the electromagnet 6; when the driving device 5 is attracted to the first adjusting member 41 alone, the driving device 5 drives the first adjusting member 41 to rotate independently; when the driving device 5 is attracted to the second adjusting member 42 alone, the driving device 5 drives the second adjusting member 42 to rotate independently; when the driving device 5 is attracted to the third adjusting member 43 alone, the driving device 5 drives the third adjusting member 43 to rotate independently; when the driving device 5 is attracted to the fourth adjusting member 44 alone, the driving device 5 drives the fourth adjusting member 44 to rotate independently; in this way, the positions of the first dividing member 411, the second dividing member 421, the third dividing member 431 and the fourth dividing member 441 can be adjusted independently.

[0040] The driving device 5 is a transmission shaft connected to the motor, and the transmission shaft is passed through the filter 3, the first adjusting member 41, the second adjusting member 42, the third adjusting member 43 and the fourth adjusting member 44; the electromagnet is arranged on the transmission shaft; magnetic blocks (not shown in the figure) are respectively provided on the first adjusting member 41, the second adjusting member 42, the third adjusting member 43 and the fourth adjusting member 44.

[0041] When the driving device 5 is simultaneously attracted with the first adjusting member 41, the second adjusting member 42, the third adjusting member 43, and the fourth adjusting member 44, the driving device 5 can drive the first adjusting member 41, the second adjusting member 42, the third adjusting member 43, and the fourth adjusting member 44 to rotate simultaneously. This makes it easy to adjust the number of partitions on the filter hole. The driving device 5 drives the adjusting device to rotate, thereby changing the position of the partition, and the structure is simple. At the same time, the adjusting members are magnetically connected to the driving device 5. When the driving device 5 is magnetically connected to one of the adjusting members, the driving device 5 can drive one adjusting member to rotate alone; when the driving device 5 is magnetically connected to all the adjusting members, the driving device 5 can drive all the adjusting members to rotate at the same time; the reliability is good. The explosion pipe 2 is connected to an air intake pipe 21, and the air inlet 22 of the air intake pipe 21 is located above the liquid level 10 in the incubator 1. A first control valve 23 is provided on the air intake pipe 21. The air inlet 22 of the air inlet pipe 21 is arranged above the liquid surface to realize normal air supply to the aeration pipe 2 , and a first control valve 23 is arranged to control the flow rate of the air inlet, thereby adjusting the flow rate output by the aeration pipe 2 .

[0042] The incubator 1 is connected to a water outlet pipe 13, on which a second control valve 14 is provided. The second control valve 14 is provided on the water outlet pipe 13 to control the flow of drainage; the water outlet pipe 13 is used to discharge Artemia separated from the egg shell. In a preferred embodiment, the incubator 1 is a conical structure, and the width of the bottom of the incubator 1 is smaller than the width of the top of the incubator 1; the water outlet pipe 13 is provided close to the bottom of the incubator 1, and the incubator 1 with a conical structure has good fluidity and is convenient for drainage; at the same time, it is convenient to collect Artemia that cannot be discharged from the incubator 1.

[0043] The incubator 1 is also provided with a light source 7, which is located below the level of the output end of the aeration tube 2; the light source 7 is arranged on the outer wall of the incubator 1, and the incubator 1 is a light-transmitting incubator 1. The light source 7 is arranged in the incubator 1, and because Artemia has phototropism, the Artemia larvae are attracted by the light source, so that the Artemia larvae move closer to the light source; at the same time, the light source 7 is located below the aeration tube, and the Artemia larvae approaching the light source are located below the output end of the aeration tube, so that when the aeration tube sprays gas upward, it will not cause damage to the Artemia larvae.

[0044] In a preferred embodiment, a cover plate 8 is provided on the top of the incubator 1, and the cover plate 8 is provided to cover the incubator 1, so as to facilitate the hatching of Artemia. After the egg shells pass through the filtering device, the cover plate 8 is opened to collect the egg shells.

[0045] The working principle of the utility model is as follows: the explosion tube 2 is started to provide oxygen for the growth of Artemia worms and separate Artemia worm larvae from egg shells; then the driving device 5 rotates the first adjusting member 41, the second adjusting member 43 and the fourth adjusting member 44 respectively, so that the first dividing member 411, the second dividing member 421, the third dividing member 431 and the fourth dividing member 441 are staggered, and then the light source member 7 is started to attract Artemia worm larvae.

[0046] Then, the output flow of the explosion tube 2 is increased, and the gas ejected from the explosion tube 2 drives the small-volume egg shells to pass through the filter channel 31 and separate the Artemia larvae; the egg shells passing through the filter device are collected; then the driving device 5 drives the third adjusting member 43 and the fourth adjusting member 44 to rotate, and moves the third dividing member 431 and the fourth dividing member 441 to the bottom of the second dividing member 421, thereby reducing the number of projections of the dividing members in the filter channel 31 and increasing the passing area of ​​the filter channel 31. At this time, the gas ejected from the explosion tube 2 will drive the large-volume egg shells to pass through the filter channel 31 and separate the Artemia larvae; the egg shells passing through the filter device are collected.
