Description

Technical Field

[0001] This application relates to the technical field of aquaculture, and in particular to a filter device for insect eggs and shells. Background Technology

[0002] Artemia eggs are an important aquaculture feed widely used in the aquaculture field, and have high nutritional value.

[0003] Artemia eggs are often used in the rearing of fish fry. After hatching, the Artemia eggs are mixed with the shells. Fish fry, shrimp fry and other juveniles are prone to indigestion when they eat the shells, which is not conducive to fry rearing and breeding. Summary of the Invention

[0004] To facilitate the smooth progress of seedling cultivation and breeding, this application provides an insect egg and shell filtration device.

[0005] This application provides a filter device for insect eggs and shells, which adopts the following technical solution:

[0006] An insect egg and shell filtration device includes an egg-collecting box, a shell-collecting box, a water filter element, and a filtration assembly. The egg-collecting box and the shell-collecting box abut against each other and both have upward openings. The water filter element is detachably installed in the egg-collecting box and has water filter holes for allowing water flow and trapping insect eggs. The filtration assembly is flipped between the egg-collecting box and the shell-collecting box so that the filtration assembly is opposite to the opening of the egg-collecting box or the opening of the shell-collecting box.

[0007] The filtration assembly includes a mounting frame and an egg filter element. One side of the mounting frame is rotatably connected to the side of the egg collection box near the shell collection box. The egg filter element is mounted on the mounting frame and has egg filter holes for allowing water flow and insect eggs to pass through while trapping insect shells. When the mounting frame is rotated so that the egg filter element is opposite to the egg collection box, the egg filter element is positioned above the water filter element.

[0008] By adopting the above technical solution, after the egg filter is moved above the water filter, the insect eggs and shells are placed into the egg filter, and the egg filter is flushed with water, causing the eggs and water to fall from the egg filter holes into the water filter, thus separating the eggs from the shells. After the eggs and shells are separated, the filter assembly is flipped so that it faces the shell collection box, allowing the accumulated shells in the egg filter to be poured into the shell collection box for collection, thereby completing the separation of eggs and shells and promoting the smooth progress of seedling cultivation and breeding.

[0009] Optionally, the part of the egg filter that receives the material is made of a flexible material, and the egg filter deforms under its own gravity when it is opposite to the egg box or the shell box to form an upward-facing receiving cavity.

[0010] By adopting the above technical solution, the flexible material allows the egg filter to deform, so that when the egg filter is opposite to the egg-holding box, the upward-opening accommodating cavity receives the material, and when the egg filter is opposite to the shell-holding box, it deforms downward and drives the insect shell to move, making it easier for the insect shell to detach from the egg filter and enter the shell-holding box.

[0011] Optionally, the filter assembly further includes a water collection component, a support component, a telescopic power source, and a rotation source. The telescopic power source is installed on the end of the mounting frame away from the filter element and connected to the water collection component to drive the water collection component to move towards or away from the filter element. The support component is hinged to the side of the mounting frame, and the rotation source is installed on the mounting frame to drive the support component to rotate, so that the support component is in a first position or a second position. The water collection component includes a water collection bag and an abutment ring. The part of the water collection bag that receives the material is made of a flexible and waterproof material. The water collection bag has an arc-shaped structure, and the abutment ring is coaxially connected to the arc opening of the water collection bag.

[0012] When the support member is in the first position and the telescopic power source is fully extended, the support member supports the abutment ring so that the arc opening of the water collection bag is away from the filter egg member; when the support member is in the second position and separated from the abutment ring, or when the telescopic power source is fully retracted, the arc opening of the water collection bag faces downward.

[0013] By adopting the above technical solution, water is collected in the water collection bag, and the water in the water collection bag is driven to the filter egg element by the telescopic power source locking. This causes the water to flow from the water collection bag to the filter egg element in a circumferential direction, so that water first accumulates in the filter egg element to disturb and flush up the insect eggs and shells. Then, the water and insect eggs are gradually discharged through the filter egg holes, thereby improving the filtering effect of the filter egg element on insect eggs.

[0014] Optionally, the filter element is provided with a limiting ring. When the filter element is opposite to the egg-holding box, and the telescopic power source is fully extended while the arc opening of the water-collecting bag is facing downward, the abutting ring and the limiting ring are coaxial and abut against each other, and the water-collecting bag and the filter element together form a closed receiving cavity.

[0015] By adopting the above technical solution, the stability of the water collection bag and the egg filter element in enclosing the insect shell is improved through the abutment of the limiting ring and the abutting ring.

[0016] Optionally, the insect egg and shell filtration device further includes a water outlet component, which includes a main pipe and a branch pipe connected and communicating with each other. The end of the branch pipe away from the main pipe is the water outlet, and the branch pipe rotates on the main pipe so that it can rotate to be opposite to the egg collection box or the shell collection box, or rotate to be simultaneously misaligned with the egg collection box and the shell collection box. When the branch pipe is opposite to the egg collection box and the mounting bracket is opposite to the egg collection box, the water outlet faces the water collection bag. When the branch pipe is opposite to the shell collection box and the mounting bracket is opposite to the shell collection box, the water outlet faces the egg filter component.

[0017] By adopting the above technical solution, the branch pipe rotates on the main pipe, which can quickly change the orientation of the outlet, improving the convenience of water supply to the egg tank and shell tank.

[0018] Optionally, the egg-holding box includes a main box, an extension group, a rotating shaft, and a support shaft. The main box has an upward-facing opening. The extension group is provided in two sets and is respectively located on both sides of the main box near and away from the egg-holding box. Each extension group includes two extension columns located on the top of the main box. There is space between the two extension columns in the same group for the mounting frame to move.

[0019] The two ends of the rotating shaft are respectively connected to two extension columns on the side closer to the shell-holding box, and the two ends of the support shaft are respectively connected to two extension columns on the side away from the shell-holding box. One side of the mounting frame is connected to a swing sleeve that is swung around the outer wall of the rotating shaft to flip the mounting frame. When the mounting frame is opposite to the egg-holding box, the side of the mounting frame away from the swing sleeve is supported by the support shaft.

[0020] By adopting the above technical solution, the swing sleeve rotates on the rotating shaft to drive the entire mounting frame to flip.

[0021] Optionally, the outer wall of the extension column is fitted with a mounting base for connecting the water filter element.

[0022] Optionally, both the support shaft and the rotating shaft slide up and down on the extension column, and a first elastic element is provided between the support shaft and the corresponding mounting seat, and between the rotating shaft and the corresponding mounting seat.

[0023] By adopting the above technical solution, during the water filtration process in the filter element, the rotating shaft and the first elastic element cooperate to make the rotating shaft swing up and down at the extension column, thereby disturbing the water flow in the filter element and improving the filter effect of the filter element.

[0024] Optionally, the mounting base slides up and down on the extension column, and a second elastic element is provided between the mounting base and the top of the main box.

[0025] By adopting the above technical solution, when the filter element shakes up and down, the mounting base and the second elastic element work together to drive the mounting base to shake up and down, thereby causing the filter element to shake, which disturbs the water flow in the main tank and increases the dissolved oxygen content in the water in the main tank.

[0026] Optionally, both the egg-holding box and the shell-holding box are equipped with water outlet pipes.

[0027] By adopting the above technical solution, the water outlet pipe can balance the water level in the egg-holding tank and the shell-holding tank, making it less likely for water to overflow.

[0028] In summary, this application has the following beneficial effects:

[0029] The egg filter is positioned opposite the egg collection box. The egg filter filters the eggs from the mixture of eggs and shells into the water filter. The egg filter is then moved to face the shell collection box, allowing the shells collected in the egg filter to fall into the shell collection box for collection. This process separates the eggs from the shells, enabling the eggs to be fed during seedling cultivation, thus promoting the smooth progress of seedling cultivation and breeding.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses an insect egg and shell filtering device. (Refer to...) Figure 1 The insect egg and shell filtration device includes an egg collection box 1, a shell collection box 2, a water filter element 3, a filter assembly, and a water outlet element 14. The water filter element 3 is installed in the egg collection box 1 to collect insect eggs, and the shell collection box 2 is placed on one side of the egg collection box 1 to collect insect shells. The filter assembly rotates on the egg collection box 1, and when it rotates, it flips between the egg collection box 1 and the shell collection box 2, so that the filter assembly filters out insect eggs at the egg collection box 1 and pours insect shells into the shell collection box 2. The water outlet element 14 is installed on one side of the egg collection box 1 and the shell collection box 2, and is used to flush water into the shell collection box 2 or the egg collection box 1 to assist in the discharge of insect eggs and shells. The insect eggs are smaller than the insect shells.

[0037] Both the egg-collecting box 1 and the shell-collecting box 2 are square and have upward-facing openings. One side of the egg-collecting box 1 and one side of the shell-collecting box 2 abut against each other and fit together. The water filter 3 includes a first fixing ring 31 and a water filter bag 32. The water filter bag 32 is made of nylon mesh and has an upward-facing arc-shaped structure. The first fixing ring 31 is fixedly sleeved around the arc opening of the water filter bag 32 and can be detachably connected to the egg-collecting box 1. The mesh of the water filter bag 32 is a water filter hole 4. The diameter of the water filter hole 4 is smaller than the diameter of the insect egg, so that the water filter bag 32 can allow water to flow through and intercept the insect eggs. The water filter bag 32 is fixed with a fixing strip (not shown in the figure) to maintain the arc shape of the water filter bag 32.

[0038] Reference Figure 1 and Figure 2 The filter assembly rotates on the side of the egg-collecting tank 1 closest to the shell-collecting tank 2. The filter assembly includes a mounting frame 5, an egg-filtering element 6, a water-collecting element 9, a support element 10, a telescopic power source 11, and a rotation source 12.

[0039] The mounting frame 5 includes two connecting rings 51, two connecting rods 52, and two long rods 53. The two ends of each connecting rod 52 are fixed to the two connecting rings 51 respectively. The two connecting rods 52 are symmetrically distributed around the circumference of the connecting rings 51, and their distribution direction is perpendicular to the distribution direction of the egg-holding box 1 and the shell-holding box 2. The length direction of the connecting rods 52 is parallel to the axis of the connecting rings 51. Two long rods 53 are fixed to the connecting rods 52 located on opposite sides of the connecting rings 51. The length direction of the swing rods 53 is perpendicular to the length direction of the connecting rods 52, and one end of the swing rod 53 rotates to the side of the egg-holding box 1 closest to the shell-holding box 2. The rotation of the swing rods 53 causes the mounting frame 5 to rotate, so that the connecting rings 51 are opposite the opening of the egg-holding box 1 or the opening of the shell-holding box 2, and the axis of the connecting rings 51 extends vertically.

[0040] The egg filter 6 includes a second fixing ring 61 and an egg filter pouch 62. The egg filter pouch 62 is an arc-shaped mesh pouch made of flexible nylon mesh. The mesh openings of the egg filter pouch 62 are egg filter holes 7. The diameter of the egg filter holes 7 is larger than the size of the insect eggs but smaller than the size of the insect shells, so that water and insect eggs can flow out of the egg filter pouch 62 through the egg filter holes 7, while the insect shells are trapped in the egg filter pouch 62. The second fixing ring 61 is fixedly fitted at the arc opening of the egg filter pouch 62, and the outer wall of the second fixing ring 61 is fixed to the connecting rod 52 and close to one of the connecting rings 51, so that the second fixing ring 61 and the connecting ring 51 are coaxially arranged. When the connecting ring 51 is opposite to the egg collection box 1 or the shell collection box 2, the egg filter pouch 62 deforms under its own weight to form an upward-opening receiving cavity 8.

[0041] The water collection component 9 includes a water collection bag 91 and an abutment ring 92. The water collection bag 91 is semi-circular and made of waterproof fabric, which is flexible and deformable. The abutment ring 92 is coaxially fixed to the arc opening of the water collection bag 91, and the outer diameter of the abutment ring 92 is smaller than the inner diameter of the second fixing ring 61. The telescopic power source 11 is a conventional multi-stage telescopic cylinder. A support rod 21 passing through the center of the connecting ring 51 is fixed on the connecting ring 51 that is away from the second fixing ring 61. The base of the telescopic power source 11 is fixed to the support rod 21 corresponding to the center of the connecting ring 51. The end of the piston of the telescopic power source 11 faces the filter bag 62 and is fixedly connected to the center of the water collection bag 91, so that the abutment ring 92 and the connecting ring 51 are coaxially arranged, and the extension distance of the piston of the telescopic power source 11 is greater than the diameter of the water collection bag 91. The extension direction of the piston is parallel to the length direction of the connecting rod 52. Therefore, when the connecting ring 51 is opposite to the egg box 1 or the shell box 2, and the abutting ring 92 and the water collection bag 91 are not in contact with other parts, the water collection bag 91 is deformed by its own weight and the weight of the abutting ring 92 until the arc opening faces downward.

[0042] Reference Figure 1and Figure 2 The support member 10 is square plate-shaped and has two members. Two support seats 22 are fixed on the connecting ring 51 closest to the second fixing ring 61. The two support seats 22 are symmetrically fixed on the connecting ring 51, and their distribution direction is parallel to the distribution direction of the egg-holding box 1 and the shell-holding box 2. Each support seat 22 has a rotating cavity 23 that penetrates both sides of the support seat 22. The two support members 10 are respectively opposite to the two support seats 22, and one end of the support member 10 rotates within the rotating cavity 23 of the corresponding support seat 22. The rotation source 12 is a rotating motor capable of forward and reverse rotation. The rotation source 12 corresponds one-to-one with the support seat 22 and is installed on the corresponding support seat 22. The output end of the rotation source 12 is connected to the support member 10 on the corresponding support seat 22, so that the rotation source 12 drives the support member 10 to rotate.

[0043] The rotation source 12 rotates at a 90° angle to drive the support member 10 to rotate to the first and second positions. When the support member 10 rotates to the first position, the length direction of the connecting rod 52 is perpendicular to the plate surface direction of the support member 10, and the ends of the two support members 10 away from the corresponding hinge seats are opposite each other and close to each other. The distance between the ends of the two support members 10 that are close to each other is less than the outer diameter of the abutment ring 92. At this time, the piston of the telescopic power source 11 is fully extended, which can drive the water collection bag 91 to pass between the two support members 10, and the two sides of the abutment ring 92 that are far from each other abut against the surfaces of the two support members 10 that are away from the second fixing ring 61, so that the arc opening of the water collection bag 91 is away from the filter egg bag 62. When the support member 10 rotates from the first position to the second position, the support member 10 rotates 90° towards the second fixing ring 61, so that the plate surface direction of the support member 10 is parallel to the length direction of the connecting rod 52. At this time, the support member 10 is housed in the rotating cavity 23 and separated from the abutment ring 92 without interfering with each other.

[0044] Reference Figure 1 and Figure 2When separating the eggs and shells, first rotate the swing rod 53 until the connecting ring 51 is opposite the opening of the egg-holding box 1. At this time, the telescopic power source 11, the water collection bag 91, and the egg filter bag 62 are arranged in order from top to bottom, with the egg filter bag 62 located above the water filter bag 32. First, make the piston of the telescopic power source 11 fully extend, and rotate the support member 10 to the first position to support the abutment ring 92, so that the arc opening of the water collection bag 91 faces upward and the opening of the receiving cavity 8 faces upward. The mixture of insect eggs and shells is then poured into the egg filter bag 62, and water is continuously supplied to the water collection bag 91 through the water outlet 14. When the water in the water collection bag 91 accumulates to near the abutment ring 92, the support member 10 is rotated to the second position and the piston of the telescopic power source 11 is fully retracted, causing the water collection bag 91 to deform into an arc-shaped downward-facing position. The water accumulated in the water collection bag 91 is flushed from the periphery of the water collection bag 91 into the egg filter bag 62, thereby flushing up the insect eggs and shells in the egg filter bag 62. The insect eggs are then carried by the water flow out through the egg filter holes 7 of the egg filter bag 62 and into the egg collection box 1. While the insect eggs are being filtered in the egg filter bag 62 with the water flow, the water collection bag 91 is moved back to the position supported by the support member 10 on the abutment ring 92, and water is collected again. The water collection speed of the water collection bag 91 is comparable to the water filtration speed of the egg filter bag 62. When the water in the egg filter bag 62 has drained completely, the water collection bag 91 can be flushed downwards.

[0045] Repeatedly flush the egg-collecting bag 91 against the egg-filtering bag 62 to filter out the eggs, leaving only the egg-shells in the bag. Rotate the support 10 to the second position, and the piston of the telescopic power source 11 moves to its full extension. At this time, the water-collecting bag 91 automatically transforms into a downward-facing arc-shaped state, while the abutment ring 92 abuts against the inner wall of the middle part of the egg-filtering bag 62 along its circumference, so that the water-collecting bag 91 and the egg-filtering bag 62 together form a closed cavity that collects the egg-shells. Then, close the water outlet 14 and move it to a position where it is misaligned with both the egg-collecting box 1 and the shell-collecting box 2. Then, rotate the swing rod 53 to flip the mounting bracket 5 so that the connecting ring 51 is opposite to the opening of the shell-collecting box 2.

[0046] Reference Figure 3 and Figure 4After the connecting ring 51 aligns with the opening of the shell collection box 2, the water collection bag 91 deforms under its own weight and the force of the abutment ring 92 until the arc opening faces downwards, opening the storage cavity and allowing the insect shells collected in the storage cavity to fall into the shell collection box 2. Then, the piston of the telescopic power source 11 is moved to full retraction, so that the water collection bag 91 covers the telescopic power source 11, and the abutment ring 92 abuts against the support rod. The filter egg bag 62 deforms downwards until the opening faces upwards. At this time, the water outlet 14 is moved to face the filter egg bag 62 and opened, so that the water outlet 14 flushes the filter egg bag 62, allowing the remaining attached insect shells on the filter egg bag 62 and the water collection bag 91 to flow into the shell collection box 2 with the water flow. The arc surfaces of the filter egg bag 62 and the water collection bag 91 guide the flow of insect shells and water, so that the insect shells enter the shell collection box 2 for collection. In addition, the water collection bag 91 is made of opaque material to block light above the egg filter bag 62 when it is opposite to the egg holding box 1.

[0047] Reference Figure 1 and Figure 2 Furthermore, a limiting ring 13 is fixed in the middle of the filter egg bag 62 along its own circumference. The diameter of the limiting ring 13 is the same as the diameter of the abutment ring 92. When the abutment ring 92 abuts against the filter egg bag 62 downwards, it abuts against the limiting ring 13. The surface of the limiting ring 13 is rough to increase the friction when the limiting ring 13 abuts against the abutment ring 92.

[0048] Reference Figure 1 and Figure 3 The water outlet 14 includes a main pipe 141 and a branch pipe 142. The main pipe 141 is a rigid pipe connected to an external water source (not shown in the figure). The main pipe 141 is located between one side of the egg-collecting tank 1 and the shell-collecting tank 2. The portion of the main pipe 141 opposite to the egg-collecting tank 1 and the shell-collecting tank 2 extends vertically. The top of the main pipe 141 away from the external water source is located above the egg-collecting tank 1 and the shell-collecting tank 2, and the main pipe 141 has a valve 24 for opening and closing. One end of the branch pipe 142 is rotatably connected to the end of the main pipe 141 away from the external water source and is connected to the main pipe 141. The end of the branch pipe 142 away from the main pipe 141 is the water outlet 15. The branch pipe 142 can rotate on the main pipe 141 to make the water outlet 15 opposite to the egg-collecting tank 1 or the shell-collecting tank 2, or to make the branch pipe 142 move away from the position opposite to the egg-collecting tank 1 and the shell-collecting tank 2.

[0049] Reference Figure 1 and Figure 2 When the connecting ring 51 is opposite to the egg-holding box 1, and the branch pipe 142 is rotated to be opposite to the egg-holding box 1, the branch pipe 142 is located between the two connecting rings 51 and close to the arc of the outlet 15 of the branch pipe 142 facing the water collection bag 91, and the branch pipe 142 can rotate out of the egg-holding box 1 from between the two connecting rings 51 towards the direction close to the shell-holding box 2.

[0050] Reference Figure 3 and Figure 4When the connecting ring 51 is opposite to the shell box 2, and the branch pipe 142 is rotated to be opposite to the shell box 2, the branch pipe 142 is simultaneously located above the two connecting rings 51, and the outlet 15 of the branch pipe 142 faces the filter bag 62 to clean the filter bag 62.

[0051] Reference Figure 1 and Figure 3 To enable the swing arm 53 to rotate on the egg-holding box 1, the egg-holding box 1 includes a main box 101, an extension assembly 102, a rotating shaft 103, and a support shaft 104. The main box 101 is a square cylinder with a hollow interior and an open top, and its outer wall abuts against the outer wall of the shell-holding box 2. The extension assembly 102 has two sets, which are respectively fixed to the top of the main box 101 on opposite sides near and away from the shell-holding box 2. Each extension assembly 102 includes two extension columns 1021, which are vertically extending square columns, and their bottom ends are fixed to the upper surface of the main box 101. The two extension columns 1021 in the extension assembly 102 are respectively fixed to opposite ends of the main box 101, and the distance between the two extension columns 1021 in the extension assembly 102 is [missing information].

[0052] Reference Figure 3 and Figure 4 Both the rotating shaft 103 and the support shaft 104 are round rods. The two ends of the rotating shaft 103 that are far apart from each other are respectively sleeved on two extension columns 1021 in the extension group 102 on the side of the main box 101 near the shell box 2. The two ends of the support shaft 104 that are far apart from each other are respectively sleeved on two extension columns 1021 in the extension group 102 on the side of the main box 101 far away from the shell box 2. The rotating shaft 103 and the support shaft 104 are parallel to each other.

[0053] A swing sleeve 16 is fixed to both swing rods 53. The swing sleeve 16 is coaxially rotatably sleeved on the outer wall of the rotating shaft 103, and the swing sleeve 16 and the two swing rods 53 are located between the two extension columns 1021 at opposite ends of the main box 101, so that the swing rods 53 can move between the extension columns 1021 at both ends of the main box 101. A clearance opening is provided on the upper part of the side of the container 2 near the main box 101 to allow room for the rotation of the swing sleeve 16 and the swing rods 53.

[0054] When the swing rod 53 is above the swing sleeve 16, the end of the swing rod 53 away from the swing sleeve 16 abuts against the upper part of the support shaft 104, so that the support shaft 104 and the rotating shaft 103 jointly support the mounting frame 5. At this time, the connecting ring 51 is opposite to the egg-holding box 1. Rotate the swing sleeve 16 180° towards the shell-holding box 2, so that the end of the swing rod 53 away from the swing sleeve 16 abuts against the upper surface of the shell-holding box 2 on the side away from the main box 101. At this time, the connecting ring 51 is opposite to the shell-holding box 2.

[0055] Reference Figure 3To install the filter bag 32, each extension column 1021 has a mounting base 17 fitted on its outer wall. The first fixing ring 31 is bolted to the mounting base 17 to install the filter bag 32. The lower part of the filter bag 32 enters the main tank 101, and the water level in the main tank 101 is higher than the bottom of the filter bag 32, so that the insect eggs in the filter bag 32 can continue to survive in the water of the main tank 101. When the connecting ring 51 is opposite to the shell-holding box 2, the connecting base can be removed from the mounting base 17 to facilitate the removal of the insect eggs from the filter bag 32.

[0056] Reference Figure 1 and Figure 3 Furthermore, the rotating shaft 103, the support shaft 104, and the mounting base 17 are all slidably sleeved on the connected extension column 1021. The mounting base 17 is located below the rotating shaft 103 and the support shaft 104. A first elastic element 18 is connected between the mounting base 17 and the corresponding rotating shaft 103, and between the mounting base 17 and the corresponding support shaft 104. A second elastic element 19 is connected between the mounting base 17 and the top surface of the main box 101. Both the first elastic element 18 and the second elastic element 19 are springs sleeved on the outer wall of the extension column 1021. When the water collection bag 91 pushes water towards the egg filter bag 62, the weight of the water in the egg filter bag 62 causes the rotating shaft 103 and the support shaft 104 to press down on the first elastic element 18, and in conjunction with the mounting base 17, press down on the second elastic element 19. As the water flows away, the first elastic element 18 and the second elastic element 19 drive the rotating shaft 103, the support shaft 104, and the mounting base 17 to move upward, thereby causing the egg filter bag 62 and the water filter bag 32 to shake, thereby enhancing the disturbance effect of the water flow in the egg filter bag 62, which helps the eggs to flow out, and causes the water filter bag 32 to disturb the water flow in the main tank 101, increasing the dissolved oxygen content in the water in the main tank 101, which helps the eggs survive.

[0057] Reference Figure 2 Furthermore, in order to facilitate the rotation of the swing sleeve 16, a drive motor 25 is installed on the rotating shaft 103. The drive motor 25 can rotate in both directions. A first gear 26 is coaxially fixed on the output end of the drive motor 25, and a second gear 27 is coaxially fixed on the outer wall of the swing sleeve 16. The axes of the first gear 26 and the second gear 27 are parallel to each other, and the first gear 26 and the second gear 27 mesh with each other. The drive motor 25 drives the first gear 26 to rotate, thereby driving the second gear 27 and the swing sleeve 16 to rotate.

[0058] Reference Figure 1 and Figure 3In addition, both the main tank 101 and the shell-collecting tank 2 are equipped with water outlet pipes 20 that communicate with the outside. The water outlet pipes 20 extend horizontally, and the water outlet pipe 20 on the main tank 101 is positioned opposite the middle of the filter bag 32. When the water level in the main tank 101 reaches the position of the water outlet pipe 20, it overflows from the water outlet pipe 20. The water outlet pipe 20 on the shell-collecting tank 2 is located at the bottom of the tank to supply water flow and overflow. A filter screen (not shown in the figure) is installed at the inlet of the water outlet pipe 20 of the shell-collecting tank 2 to prevent insect shells from flowing out of the tank 2.

[0059] The implementation principle of the insect egg and shell filtering device in this application embodiment is as follows: When filtering insect eggs, the mounting frame 5 is rotated to face the egg collection box 1, and the mixture of insect eggs and shells is placed into the egg filter bag 62. Water is collected through the water collection bag 91 and flushed onto the egg filter bag 62, causing the insect eggs to flow into the water filter bag 32 in the egg collection box 1. After filtering the insect eggs, the mounting frame 5 is rotated to face the shell collection box 2, and water is flushed onto the egg filter bag 62 through the branch pipe 142, causing the insect shells to be flushed into the shell collection box 2 for collection.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
