Description

Technical Field

[0001] This invention relates to shell-plasm separation technology, belonging to the field of insect processing, and specifically to a black soldier fly larvae shell-plasm separation and processing device and its usage method. Background Technology

[0002] Black soldier flies, as saprophytic insects of the family Tabanidae, can feed on poultry and livestock manure and domestic waste. They are characterized by rapid reproduction, large biomass, wide diet, high absorption and conversion rate, and low feeding cost. Their larvae are rich in protein and fat, making them a high-quality feed source. For example, the main nutrients in the dry matter of black soldier fly larvae (BSFL) include crude protein, crude fat, calcium, phosphorus, chitin, and other substances. They have great potential to replace fishmeal and reduce carbon emissions from aquaculture.

[0003] During the processing of black soldier fly larvae, it is necessary to separate the larval shell from the larval pulp. The shell contains chitin, which can promote intestinal health and enhance immunity in animals and is suitable for poultry feed. The pulp contains a high proportion of protein and amino acids and is suitable for carnivorous fish feed. In addition, the larval pulp ice particles containing fine chitin are especially suitable for aquatic feeds such as fish, shrimp and crab.

[0004] Black soldier fly larvae need to be cleaned and boiled before entering the shell-slurry separation process. Traditionally, this process uses mechanical pressing, where rollers squeeze the larvae to cause them to burst, separating the shell from the slurry. This method has the following problems: 1. Black soldier fly larvae have high toughness, elasticity, and strength. During the bursting process, they are easily deformed, making complete bursting impossible and reducing the effectiveness of shell-slurry separation; 2. Direct compression bursting easily damages the shell. Under pressure, the first point of damage is often the weakest point on the shell surface, making it difficult to control the bursting location and easily resulting in obvious defects at the bursting point; 3. The internal pressure of the black soldier fly larvae after being squeezed is high, easily causing slurry to splash. Summary of the Invention

[0005] The purpose of this invention is to provide a black soldier fly larvae shell-slurry separation and processing device, which not only achieves the needle-piercing action on black soldier fly larvae to allow the larvae slurry to flow out and avoids a large number of larvae adhering to the shell, thus affecting the needle-piercing effect, but also allows the larvae slurry to flow out or burst out preferentially from the larvae's piercing holes, reducing the damage to the larvae shell caused by direct crushing and preventing the larvae slurry from splashing after being compressed, and achieving repeated needle-piercing and squeezing of larvae on the support plate to improve the shell-slurry separation effect.

[0006] To achieve the above objectives, a black soldier fly larvae shell pulp separation and processing device is provided, comprising:

[0007] Coaxially arranged fixed body, support plate, and rotary table;

[0008] The fixed body has a cavity, and a feed port is provided above the cavity; the support plate is driven to rotate and is located inside the cavity; the rotary table is driven to reciprocate within a certain angle, and has multiple support sliders on its periphery that can approach and move away from the rotary table and are subjected to downward elastic force.

[0009] The pinwheel assembly and pressure roller are connected to the support slider and arranged radially above the support plate.

[0010] One end of the pressure roller is driven to rotate and mounted on the support slider;

[0011] The needle wheel assembly has a second needle wheel and a first needle wheel that is driven to rotate;

[0012] The first needle wheel is close to the upper surface of the support plate, and the second needle wheel is relatively far away from the upper surface of the support plate; the first needle wheel is provided with multiple first protrusions that can pierce the larvae, and the first protrusions are arranged circumferentially and then spaced axially; the second needle wheel is provided with multiple second protrusions arranged axially spaced.

[0013] The first protrusion and the second protrusion are intersected in the axial direction and close to the corresponding pinwheel;

[0014] The feed inlet, needle wheel assembly, and pressure roller are arranged in sequence, and their arrangement direction is consistent with the rotation direction of the support plate.

[0015] In some examples of the invention, a feeding roller is further included, which is arranged radially and located above the support disk; the feeding roller is driven to rotate and to nudge the larvae.

[0016] The pressure rollers are a pair, namely the first pressure roller and the second pressure roller; the first pressure roller, the needle roller assembly, the second pressure roller, and the feeding roller are arranged sequentially on the corresponding support sliders, and the arrangement direction is consistent with the rotation direction of the support plate;

[0017] Among them, the height of the horizontal section below the first pressing wheel to the support plate is higher than the height of the horizontal section below the second pressing wheel to the support plate;

[0018] The feed inlet is located near the first clamping roller.

[0019] In some examples of the present invention, the support slider is slidably mounted on the fixed plate and connected to the pressing assembly;

[0020] The pressing assembly includes: an adjusting rod, a first elastic element, and a limiting cylinder;

[0021] The adjusting rod is threaded onto the fixed plate, and the first elastic element is connected to the lower shoulder of the adjusting rod and the support slider.

[0022] The limit cylinder is installed at the lower end of the support slider for vertical adjustment.

[0023] In some examples of the present invention, the first needle wheel and the second needle wheel rotate in the same direction via a drive assembly;

[0024] The drive assembly has a gear shaft located within a support cover and a pair of driven gears;

[0025] The support cover is fixedly connected to the support slider;

[0026] The shaft end of the gear shaft passes through the support slider and extends to the outside to connect with the drive component; the gear end is respectively connected to a pair of driven gears.

[0027] One end of the first and second needle wheels is connected to a pair of driven gears.

[0028] In some examples of the present invention, the first protrusion and the second protrusion have the same structure and are arranged circumferentially first and then axially spaced.

[0029] A pair of gears are rotatably mounted on an adjusting plate, and the adjusting plate is rotatably mounted on a gear shaft;

[0030] The support cover is equipped with positioning components;

[0031] One end of the positioning component can act on the adjusting plate to lock and fix the two extreme positions of the adjusting plate's rotation;

[0032] When the adjusting disc is rotated to the first limit position, the first needle wheel is close to the upper surface of the support plate, and the second needle wheel is relatively far away from the upper surface of the support plate; when the adjusting disc is rotated to the second limit position, the second needle wheel is close to the upper surface of the support plate, and the first needle wheel is relatively far away from the upper surface of the support plate.

[0033] In some examples of the present invention, a pair of driven gears are rotatably mounted on a support plate, and the support plate is fixedly located inside a support cover;

[0034] One end of the second needle wheel is connected to the driven gear by a key and is provided with a column; the column is provided with a circumferentially closed-loop sliding groove that is offset upward in the axial direction;

[0035] The support cover is equipped with a limiting rod, one end of which slides within the groove;

[0036] When the gear rotates and the limiting rod slides within the groove, the second needle wheel reciprocates axially, enabling the second protrusion on it to reciprocate axially between adjacent first protrusions.

[0037] In some examples of the present invention, the cavity is provided with a coaxial discharge cylinder and a discharge pipe arranged from the inside to the outside;

[0038] The discharge cylinder is fixedly arranged and has a first discharge port that can connect with the upper end of the support plate; the discharge cylinder rotates relative to the discharge cylinder and has a first discharge port at the top that can connect with the first discharge port, and multiple first through holes;

[0039] The first discharge port is located near the second pressing roller or feeding roller, and a guide plate that moves up and down is provided above the first discharge port.

[0040] The feed guide plate is a radially arranged arc-shaped structure, and its inner side gradually contracts towards the first discharge port, so that the larvae gradually move inward from the outside along the feed guide plate.

[0041] In some examples of the present invention, the fixing body is provided with a plurality of second discharge ports in the circumferential direction and a storage box in the circumferential outer direction;

[0042] Each second discharge port is connected between the storage box and the upper surface of the support plate. The fixed body is equipped with a discharge plate that can move up and down and open and close the second discharge port.

[0043] The support plate is equipped with a angular material feeding plate on its periphery;

[0044] The storage bin is equipped with a filter screen that can filter insect slurry.

[0045] In some examples of the present invention, the axis of the first needle wheel is arranged at an angle to the upper end face of the support plate;

[0046] Along the axis of the first needle wheel, from the inside out, the bottom of the needle wheel assembly gradually approaches the upper surface of the support plate.

[0047] The present invention also provides a method for using a black soldier fly larvae shell-slurry separation and processing device. The black soldier fly larvae are sequentially compacted by a first pressing wheel to reduce the gaps between the larvae, pierced by a needle wheel assembly to allow the larvae slurry to flow out, squeezed by a second pressing wheel to allow the larvae slurry to flow out or burst out preferentially from the piercing holes of the larvae, and then pushed by a feeding roller to adjust the position of the larvae. This method can effectively increase the number of piercings and the squeezing effect on the larvae, reduce the damage to the larvae shell caused by direct crushing, avoid the larvae slurry splashing after being compressed, and improve the shell-slurry separation effect.

[0048] A method for using a black soldier fly larvae shell pulp separation and processing device specifically includes the following steps:

[0049] S1, the first pressing wheel, the needle wheel assembly, the second pressing wheel, and the feeding roller are arranged sequentially on the corresponding support sliders, and the arrangement direction is consistent with the rotation direction of the support plate;

[0050] The support plate is driven to rotate circumferentially;

[0051] S2, Black soldier fly larvae fall from the feed inlet onto the support plate and rotate with it;

[0052] The larvae first pass through the first compaction wheel: the rotating first compaction wheel compacts the larvae to reduce the gaps between them;

[0053] After being compacted, the larvae pass through the needle wheel assembly: the first needle wheel rotates, and the first protrusion on it acts as a needle on the larvae, so that certain holes are formed on the surface of the larvae so that the insect paste can flow out; the larvae attached to the first protrusion follow the rotation and are blocked by the second protrusion to detach, thus completing the "feeding" process, so that the attached larvae fall back onto the support plate.

[0054] After being pierced, the larvae then pass through a second compression wheel: the rotating second compression wheel squeezes the larvae, causing the insect fluid to flow out or burst out from the larvae's piercing holes first, reducing the damage to the insect shell caused by direct crushing.

[0055] After being squeezed, the larvae then pass through a feeding roller: the feeding roller is driven to rotate, which can initially separate the tightly stuck larvae and adjust their position.

[0056] After being fed, the larvae continue to pass through the first pressing wheel, completing one cycle.

[0057] S3, during the rotation of the support plate, the rotary table will drive the first pressing wheel, the needle wheel assembly, the second pressing wheel, and the feeding roller to rotate back and forth around the center of the rotary table within a certain angle, repeatedly compacting, piercing, squeezing, and feeding the larvae on the support plate to improve the shell-slurry separation effect.

[0058] S4. After the squeezing process or at least one cycle, the insect shells and insect pulp on the support plate will be collected or further separated.

[0059] Compared with existing technologies, this black soldier fly larvae shell-slurry separation and processing device, through the setting of a needle wheel assembly and a pressure roller, and the support plate driving multiple larvae through the needle wheel assembly, on the one hand, performs a needle-like action on the larvae to allow the insect slurry to flow out, and on the other hand, causes the attached larvae to detach due to the obstruction of the second protrusion, thus completing the "discharging" process. This avoids a large number of larvae attaching and affecting the needle-like action on other larvae. When the needle-like larvae pass through the pressure roller, the pressure roller squeezes the larvae, causing the insect slurry to flow out or burst out preferentially from the larvae's puncture holes, reducing the damage to the larvae shell caused by direct crushing and bursting, and avoiding the larvae being directly subjected to large pressure and causing insect slurry to splash. In addition, during the rotation of the support plate, the rotary table drives the needle wheel assembly and the pressure roller to rotate synchronously, realizing repeated needle-like action and squeezing of the larvae on the support plate, improving the shell-slurry separation effect.

[0060] Because of the material feeding roller, and the first pressing wheel, the needle wheel assembly, the second pressing wheel, and the material feeding roller are arranged sequentially on the corresponding support slider, the sequential actions of compacting, piercing, squeezing, and adjusting the material feeding of the larvae are completed. After one cycle, the larvae can be compacted again. The number of piercings and the squeezing effect on the larvae can be effectively increased by changing the different positions of the larvae.

[0061] Since the first and second needle wheels rotate in the same direction through the drive assembly, the corresponding impact effect of material feeding can be increased. In one method, a pair of driven gears are rotatably mounted on the adjustment plate, which can be locked at the two extreme positions of rotation. Therefore, without affecting the co-rotation of the first and second needle wheels, the positions of the first and second needle wheels can be switched, and the corresponding needle wheels can perform material feeding. This avoids the first or second protrusion from wearing out after long-term use, which would prevent effective needle feeding of larvae. In another method, one end of the second needle wheel is connected to the driven gear by a key. The column is provided with a circumferentially closed-loop and axially offset sliding groove, which allows the second needle wheel to move axially while rotating, avoiding excessive gaps that would cause material leakage and effectively improving the material feeding effect.

[0062] After being squeezed or fed, the larvae can be discharged from the center or periphery of the support plate. When the larvae are discharged from the periphery, along the axis of the first needle wheel and from the inside out, the needle wheel assembly gradually approaches the upper surface of the support plate. As the rotation speed of the support plate gradually increases, the larvae are moved from the inside out by centrifugal force. The first protrusion can gradually pierce the larvae to different depths, avoiding the problem that some larvae cannot be completely pierced due to differences in larval size.

[0088] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, this black soldier fly larvae shell pulp separation and processing device includes:

[0089] The fixed body 10, the support plate 20, and the rotary table 30 are arranged coaxially.

[0090] The fixed body 10 has a cavity, and a feed port 91 is provided above the cavity; the support plate 20 is driven to rotate and is located in the cavity; the rotary table 30 is driven to reciprocate within a certain angle, and has multiple elastic downward support sliders 43 on its periphery that can approach and move away from the rotary table 30.

[0091] The pinwheel assembly 50 and the pressure roller 70 are respectively mounted on the support slider 43, arranged radially and located above the support plate 20;

[0092] The needle wheel assembly 50 has a second needle wheel 52 and a first needle wheel 51 that is driven to rotate;

[0093] The first needle wheel 51 is close to the upper surface of the support plate 20, and the axis of the first needle wheel 51 is lower than the axis of the second needle wheel 52; the first needle wheel 51 is provided with a plurality of first protrusions 511 that can be needled on the larvae, and the first protrusions 511 are arranged circumferentially and then spaced axially; the second needle wheel 52 is provided with a plurality of second protrusions 524 arranged axially spaced.

[0094] The first protrusion 511 and the second protrusion 524 are intersected in the axial direction and close to the corresponding pinwheel;

[0095] Among them, the feed inlet 91, the pin wheel assembly 50, and the pressure roller 70 are arranged in sequence, and the arrangement direction is consistent with the rotation direction of the support plate 20.

[0096] Specifically, the fixed body 10 is a fixed arrangement and an integral support structure. The support plate 20 and the rotary plate 30 can be assembled with the fixed body 10 through bearings or rotary bearings. The cavity of the fixed body 10 is cylindrical with an open structure at the top and can be closed by the cover plate 90.

[0097] The support plate 20 is driven to rotate, for example, counterclockwise. That is, the lower end of the support plate 20 extends and is provided with a moving wheel. The moving wheel is driven by the driving component to realize the rotation of the support plate 20. The support plate 20 rotates and seals with the inner wall of the cavity to prevent insect shells or insect secretions from overflowing.

[0098] The rotary disk 30 is driven to reciprocate, for example, between 0-60°. As one embodiment of this reciprocating rotation, a main gear may be provided at the lower end of the rotary disk 30. A slidably arranged rack meshes with the main gear, and the rack is mounted on a slider. This slider is a crank-slider mechanism that reciprocates, thereby driving the main gear and the rotary disk 30 to reciprocate within a certain angle. As another embodiment, a main gear driven by a motor may be provided at the lower end of the rotary disk 30. An identifier is provided on the rotary disk 30, and a fixedly arranged photoelectric sensor can match the identifier. After the main gear drives the rotary disk 30 to rotate a certain angle in the forward direction, the photoelectric sensor and the identifier match. Then, the main gear drives the rotary disk 30 to rotate a certain angle in the reverse direction. Figure 1 , Figure 4 As shown, multiple strip-shaped grooves 11 can be provided on the fixed body 10, which facilitate one end of the pin wheel assembly 50 and the pressure roller 70 to pass through the fixed body 10 and be rotatably connected to the support slider 43. Further, as shown... Figure 8 As shown, an elastic membrane 12 is provided between the strip groove 11 and the pin wheel assembly 50 and the pressure roller 70, which can ensure that the pin wheel assembly 50 and the pressure roller 70 form a seal when they reciprocate to prevent insect slurry from splashing out; it can be noted that the elastic membrane 12 can be a folding baffle or a flexible plastic film.

[0099] The support slider 43 is mounted on the rotary table 30 via the fixing plate 44 and is located on the outside of the fixing body 10;

[0100] The needle wheel assembly 50 is used to puncture the larvae to facilitate the discharge of insect paste from the puncture holes; the first needle wheel 51 is driven to rotate, and the second needle wheel 52 can rotate in the same direction or remain stationary, preferably rotating in the same direction. The first protrusion 511 and the second protrusion 524 can be needle-shaped or irregularly angular structures. The first protrusion 511 can puncture the larvae, and the second protrusion 524 can feed the attached larvae. In the circumferential direction, the first protrusions 511 need to be arranged more closely, and in the axial direction, the first protrusions 511 and the second protrusions 524 are arranged at intervals and can be staggered. Figure 10 As shown, axially, the second protrusion 524 is located between the adjacent first protrusion 511 and close to the first pinwheel 51;

[0101] The pressure roller 70 is rotatably mounted on the support slider 43 and can be driven to rotate for squeezing the larvae;

[0102] When this black soldier fly larvae shell pulp separation and processing device is in use, the feed inlet 91, the pin wheel assembly 50, and the pressure roller 70 are arranged counterclockwise in sequence. At this time, the support plate 20 is driven to rotate counterclockwise, and the pin wheel assembly 50 and the pressure roller 70 are close to the support plate 20.

[0103] Black soldier fly larvae enter the support plate 20 inside the cavity through the feed inlet 91. It is explained that the feed inlet 91 can be a long strip structure and can be equipped with a uniform distribution mechanism to ensure that the larvae are laid flat on the support plate 20.

[0104] The support plate 20 drives multiple larvae to first pass through the needle wheel assembly 50, that is, the first needle wheel 51 near the support plate 20 rotates, and the first protrusion 511 on it acts as a needle on the larvae, so that a certain puncture hole is formed on the surface of the larvae so that the insect paste can flow out. After the first needle wheel 51 rotates and needles, some larvae will attach to the first protrusion 511. The second protrusion 524 on the second needle wheel 52 intersects with the first protrusion 511 on the first needle wheel 51. The larvae attached to the first protrusion 511 follow the rotation and are blocked by the second protrusion 524 and detach, thus completing the "feeding" process. This allows the attached larvae to fall back onto the support plate 20, avoiding a large number of larvae attaching to the first needle wheel 51 and affecting the needleing of other larvae.

[0105] After being needled, the larvae continue to rotate on the support plate 20 and pass through the pressure roller 70. The pressure roller 70 squeezes the larvae, causing the insect pulp to flow out or burst out from the larvae's puncture holes first, reducing the damage to the insect shell caused by direct crushing and preventing the insect pulp from splashing due to excessive pressure on the larvae. During the rotation of the support plate 20, the rotary plate 30 rotates, that is, the rotary plate 30 drives the needle wheel assembly 50 and the pressure roller 70 to reciprocate around the center of the rotary plate 30 in sync. The rotation of the rotary plate 30 and the support plate 20 work together to repeatedly needle and squeeze the larvae on the support plate 20, improving the shell pulp separation effect.

[0106] The larvae, after being squeezed, can form shells and larvae pulp, which can then be collected and further separated.

[0107] During the needle-punching process of the needle wheel assembly 50 and the squeezing process of the pressure roller 70, the needle wheel assembly 50 and the pressure roller 70 are respectively mounted on the support slider 43. The support slider 43 is subjected to a downward elastic force, which allows the needle wheel assembly 50 and the pressure roller 70 to fit against the support plate 20 to a certain extent. When encountering larvae with greater hardness or heavy stacking, the support slider 43 can move upward away from the support plate 20. That is, the needle wheel assembly 50 or the pressure roller 70 moves upward appropriately to avoid the corresponding larvae, effectively protecting the needle wheel assembly 50 or the pressure roller 70.

[0108] In some examples of the present invention, such as Figure 3 As shown, the black soldier fly larvae shell pulp separation and processing device further includes: a feeding roller 60 arranged radially and located above the support plate 20; the feeding roller 60 is driven to rotate and tosses the larvae.

[0109] The pressure rollers 70 are a pair, namely the first pressure roller 71 and the second pressure roller 72; the first pressure roller 71, the needle roller assembly 50, the second pressure roller 72, and the feed roller 60 are arranged sequentially on the corresponding support sliders 43, and the arrangement direction is consistent with the rotation direction of the support plate 20.

[0110] Among them, the height of the horizontal section below the first pressing wheel 71 to the support plate 20 is higher than the height of the horizontal section below the second pressing wheel 72 to the support plate 20;

[0111] The feed inlet 91 is located near the first clamping roller 71;

[0112] Specifically, the feeding roller 60 may be equipped with a brush to facilitate the feeding of larvae, and one end may be mounted on the support slider 43 by a bearing and extend outward to connect with the drive component, which drives the feeding roller 60 to rotate.

[0113] The support plate 20 can be divided into four areas: A, B, C, and D. There are four support sliders 43, which are arranged circumferentially in the four areas: A, B, C, and D. At this time, the first pressing wheel 71, the needle wheel assembly 50, the second pressing wheel 72, and the feeding roller 60 are connected to the support slider 43 and can rotate back and forth synchronously. That is, the first pressing wheel 71 is located in area A, ..., and the feeding roller 60 is located in area D.

[0114] The first pressing wheel 71 can be structurally the same as the second pressing wheel 72. The difference is that the installation height of the first pressing wheel 71 is slightly higher than that of the second pressing wheel 72. The larvae enter area A from the feed inlet 91. The first pressing wheel 71 is used to initially compact the larvae after feeding to reduce the gap between the larvae and facilitate the needle wheel assembly 50 to perform needle-piercing action on the overlapping larvae.

[0115] After being compacted, the larvae enter area B, where the needle wheel assembly 50 needles the larvae. The needled larvae then enter area C, where the second pressing wheel 72 squeezes the larvae, causing the insect paste to separate from the insect shell. The squeezed larvae will be tightly bound together and then enter area D.

[0116] The feeding roller 60 in area D is driven to rotate. The feeding roller 60 can initially separate the tightly stuck larvae and adjust their position to complete one cycle.

[0117] When collecting insect shells and insect pulp, the larvae complete at least one cycle. That is, the larvae are pushed by the feeding roller 60 to change their position and re-enter area A for compaction, and then enter area B for needle-piercing treatment. Because the larvae are pushed apart and their position changes after the cycle, the needle wheel assembly 50 in area B can needle-pierce different positions of the larvae. Area C continues to squeeze the needle-pierced larvae, thus effectively increasing the number of needle-piercings on the larvae and improving the shell-pulp separation effect.

[0118] In some examples of the present invention, such as Figure 2 , Figure 4 , Figure 5 As shown, the support slider 43 is slidably mounted on the fixed plate 44 and connected to the pressing assembly 40.

[0119] The pressing assembly 40 includes: an adjusting rod 41, a first elastic element 42, and a limiting cylinder 45;

[0120] The adjusting rod 41 is threaded onto the fixed plate 44, and the first elastic element 42 is connected to the lower shoulder of the adjusting rod 41 and the supporting slider 43.

[0121] The limiting cylinder 45 is adjusted up and down and installed at the lower end of the support slider 43;

[0122] Specifically, the fixing plate 44 can be fixed to the edge of the fixing body 10 by bolts or welding, and the supporting slider 43 slides up and down on the fixing plate 44 by the slide rail;

[0123] In this example, during initial use, the position of the limiting cylinder 45 can be adjusted to limit the downward movement of the support slider 43 to its extreme position, for example... Figure 5 As shown, a fixed cylinder 46 is provided on the fixed plate 44, and the lower part of the limiting cylinder 45 is threadedly connected to the fixed cylinder 46, thereby realizing up and down adjustment;

[0124] Once the position of the limiting cylinder 45 is determined, the adjusting rod 41 is rotated to move the adjusting rod 41 up and down. Since the first elastic element 42 is provided between the shoulder of the adjusting rod 41 and the supporting slider 43, and the lower end of the supporting slider 43 contacts the limiting cylinder 45 for limiting, the adjustment of the supporting slider 43 by the force of the first elastic element 42 is realized, so as to be suitable for compaction, needle piercing, squeezing and feeding of larvae.

[0125] As can be seen, the position of the adjustable limiting cylinder 45 can be changed to change the position of the support slider 43, thereby adjusting the height of the first pressing wheel 71 and the second pressing wheel 72 to complete the corresponding compaction and extrusion processes.

[0126] In some examples of the present invention, such as Figure 5 , Figure 6 , Figure 7 As shown, the first needle wheel 51 and the second needle wheel 52 rotate in the same direction through a drive assembly;

[0127] The drive assembly has a gear shaft 53 located within a support cover 47 and a pair of driven gears 54.

[0128] The support cover 47 is fixedly connected to the support slider 43;

[0129] The shaft end of the gear shaft 53 passes through the support slider 43 and extends to the outside to connect with the drive component; the gear end is respectively connected to a pair of driven gears 54.

[0130] One end of the first needle wheel 51 and the second needle wheel 52 are respectively connected to a pair of driven gears 54;

[0131] Specifically, when the second needle wheel 52 is in a fixed state, the impact of the second protrusion 524 on the first protrusion 511 on the first needle wheel 51 is small, and the feeding effect is reduced. For example, some larvae may "spin" on the first protrusion 511. Therefore, the first needle wheel 51 and the second needle wheel 52 are rotated in the same direction to increase the corresponding feeding impact effect.

[0132] The support cover 47 is a sealed structure, which is connected to the support slider 43 through a sleeve. The shaft end of the gear shaft 53 passes through the sleeve, is rotatably connected to the support slider 43 through a bearing, and extends to the outside to connect with the drive component.

[0133] The driving component can be a motor, a first gear connected to the output end of the motor, and a second gear fixed to the end side of the gear shaft 53. The first gear and the second gear are meshed together. That is, after the motor starts, the gear shaft 53 is rotated by meshing the first gear and the second gear. The gear shaft 53 is meshed with a pair of driven gears 54 respectively, so that the pair of driven gears 54 rotate in the same direction, completing the same-direction rotation of the corresponding connected first pinwheel 51 and second pinwheel 52.

[0134] In some examples of the present invention, such as Figure 5 , Figure 6 , Figure 7 As shown, the first protrusion 511 and the second protrusion 524 have the same structure and are arranged circumferentially first and then axially spaced.

[0135] A pair of gears 54 are rotatably mounted on an adjusting disc 55, and the adjusting disc 55 is rotatably mounted on a gear shaft 53;

[0136] The support cover 47 is provided with a positioning element 48;

[0137] One end of the positioning component 48 can act on the adjusting plate 55 to lock and fix the two extreme positions of the rotation of the adjusting plate 55.

[0138] When the adjusting disc 55 is rotated to the first limit position, the first needle wheel 51 is close to the upper surface of the support disc 20, and the second needle wheel 52 is relatively far away from the upper surface of the support disc 20; when the adjusting disc 55 is rotated to the second limit position, the second needle wheel 52 is close to the upper surface of the support disc 20, and the first needle wheel 51 is relatively far away from the upper surface of the support disc 20.

[0139] Specifically, the positioning element 48 can be a positioning rod structure, that is, the support cover 47 is provided with an arc-shaped groove, the rod body of the positioning element 48 is threaded on the adjusting plate 55 and can slide in the arc-shaped groove, with the rod head in contact with the support cover 47; when the adjusting plate 55 is locked, the positioning element 48 rotates so that the rod head contacts the support cover 47 for locking; when the adjusting plate 55 is adjusted in angle, the positioning element 48 rotates in the opposite direction so that it slides in the arc-shaped groove.

[0140] Alternatively, a pair of positioning holes are provided on the periphery of the adjusting plate 55. The positioning holes are located at the two extreme positions of the rotation of the adjusting plate 55. The positioning element 48 is threadedly connected to the support cover 47. When the adjusting plate 55 is locked and fixed, the positioning element 48 rotates so that one end is inserted into the positioning hole of the adjusting plate 55. When the adjusting plate 55 is adjusted in angle, the positioning element 48 disengages from the positioning hole and is inserted into other positioning holes after the adjusting plate 55 has rotated a certain angle.

[0141] The adjusting disc 55 rotates around the center of the gear shaft 53 and within a certain angle range. The two extreme positions of this angle allow the positions of the first needle wheel 51 and the second needle wheel 52 to be mirrored and interchanged. That is, the first extreme position is the initial state. The first needle wheel 51 performs needle-piercing treatment on the larvae on the support disc 20, and the second needle wheel 52, which rotates in the same direction, performs feeding treatment on the larvae attached to the first needle wheel 51, so as to avoid a large number of larvae attaching to the first needle wheel 51 and affecting the needle-piercing of other larvae.

[0142] When the first protrusion 511 on the first needle wheel 51 wears down after prolonged use and can no longer effectively puncture the larvae, the adjusting disc 55 rotates and switches from the first extreme position to the second extreme position. At this time, the second needle wheel 52 performs needle puncture treatment on the larvae on the support disc 20, and the first needle wheel 51, which rotates in the same direction, performs feeding treatment on the larvae attached to the second needle wheel 52, so as to avoid a large number of larvae attaching to the second needle wheel 52 and affecting the needle puncture of other larvae.

[0143] As explained, while the adjusting disc 55 rotates, a pair of driven gears 54 rotate around the gear shaft 53 accordingly. Therefore, without affecting the rotation of the first needle wheel 51 and the second needle wheel 52 in the same direction, the position of the first needle wheel 51 and the second needle wheel 52 is switched, and the corresponding needle wheels are subjected to feeding treatment. This avoids the first protrusion 511 or the second protrusion 524 from wearing out after long-term use, which would prevent them from effectively piercing the larvae.

[0144] In some examples of the present invention, such as Figures 8 to 10 A pair of gears 54 are rotatably mounted on the support plate 56, and the support plate 56 is fixedly located inside the support cover 47;

[0145] One end of the second pinwheel 52 is connected to the driven gear 54 by a key and is provided with a column 521; the column 521 is provided with a circumferentially closed-loop sliding groove that is offset upward in the axial direction;

[0146] The support cover 47 is provided with a limiting rod 522, one end of which slides within the groove;

[0147] When the gear 54 rotates and the limiting rod 522 slides in the groove, the second needle wheel 52 moves axially back and forth so that the second protrusion 524 on it can move axially between adjacent first protrusions 511 on the first needle wheel 51.

[0148] Specifically, in the axial direction, although the first protrusion 511 and the second protrusion 524 are arranged alternately, there is still a certain gap. Since the larvae themselves are not large, the second protrusion 524 is prone to the problem of being unable to prevent them from detaching and feeding. That is, the larvae are still attached to the first protrusion 511 and located in the gap, unable to feed.

[0149] The second needle wheel 52 can be connected to the corresponding driven gear 54 via a spline or flat key to ensure that the second needle wheel 52 can move axially while rotating circumferentially; while the first needle wheel 51 can be normally connected to the driven gear 54, that is, the first needle wheel 51 only rotates and does not move axially; the column 521 is coaxially fixed on the second needle wheel 52 and is provided with a circumferential closed-loop sliding groove; the limiting rod 522 on the support cover 47 can be subjected to elastic force towards the column 521, that is, the limiting rod 522 is slidably arranged and fitted with a second elastic element 523, one end of the second elastic element 523 contacts the shoulder of the limiting rod 522 and the other end contacts the inner wall of the support cover 47. Under the action of the second elastic element 523, one end of the limiting rod 522 is elastically embedded in the sliding groove; the second needle wheel 52 slides through the support cover 47;

[0150] In this example, when the gear shaft 53 drives the driven gear 54 to rotate, the driven gear 54 drives the second needle wheel 52 to rotate via a key. The limiting rod 522 slides within the groove, and the groove has an axial offset, so that the second needle wheel 52 moves axially while rotating. This movement is slightly less than the axial distance between adjacent first protrusions 511. That is, the second protrusion 524 moves axially to the first protrusion 511 on one side to feed material, and then moves axially to the second protrusion 524 on the other side to feed material, avoiding excessive gaps that may cause material leakage and effectively improving the feeding effect.

[0151] When the larvae are discharged after being squeezed or pulled, they can be discharged from the middle or the periphery of the support plate 20.

[0152] When material is discharged from the middle of the support plate 20, such as Figure 11 , Figure 12 As shown, the cavity is provided with a coaxial discharge cylinder 82 and a discharge cylinder 81 arranged from the inside to the outside;

[0153] The discharge cylinder 81 is fixedly arranged and has a first discharge port 811 that can be connected to the upper end of the support plate 20; the discharge cylinder 82 rotates relative to the discharge cylinder 81 and has a first discharge port 821 that can be connected to the first discharge port 811 and a plurality of first through holes 822 on its upper part.

[0154] The first discharge port 811 is located near the second pressing wheel 72 or the feeding roller 60, and a guide plate 93 that moves up and down is provided above the first discharge port 811.

[0155] The guide plate 93 is a radially arranged arc-shaped structure, and its inner side gradually contracts towards the first discharge port 811, so that the larvae gradually move inward from the outside along the guide plate 93.

[0156] Specifically, the discharge cylinder 81 is rotary sealed with the support plate 20 and is provided with a first discharge port 811 located in area C or area D, that is, the first discharge port 811 discharges the larvae after squeezing or dispensing.

[0157] The guide plate 93 is radially arranged and located in area C or D, and can avoid the reciprocating rotation of the second pressing wheel 72 and the feeding roller 60; the cavity can be closed by the cover plate 90, which is provided with a feed inlet 91 and a driving component 92. The driving component 92 can be a hydraulic cylinder or an electric cylinder, and its output end is connected to the guide plate 93 to realize the up and down movement of the guide plate 93; the guide plate 93 is a spiral or involute arc structure, which can realize the adaptive centripetal movement of the larvae through its geometric shape;

[0158] When the larvae are compacted, needled, and squeezed, the guide plate 93 moves away from the support plate 20; when the next cycle begins or after the extrusion is completed, the guide plate 93 moves downward so that its lower end fits against the upper end of the support plate 20. The support plate 20 continues to rotate, and the larvae move inward along the guide plate 93 through the guiding process of the guide plate 93.

[0159] Initially, the discharge cylinder 82 closes the first discharge port 811, meaning that the first discharge port 821 and the first through hole 822 on the discharge cylinder 82 are misaligned with the first discharge port 811 on the discharge cylinder 81, preventing larvae from being discharged from the first discharge port 821. When slurry discharge is required, the discharge cylinder 82 is rotated so that the multiple first through holes 822 on the discharge cylinder 82 align with the first discharge port 811, allowing the slurry to be discharged from the first discharge port 811 and the first through hole 822. When both the insect shells and the slurry are being discharged, the discharge cylinder 82 is rotated so that the first discharge port 821 on the discharge cylinder 82 aligns with the first discharge port 811, allowing the insect shells and slurry to be discharged from both the first discharge port 811 and the first discharge port 821.

[0160] When material is discharged from the periphery of support plate 20, such as Figure 13 , Figure 14 As shown, the fixed body 10 has multiple second discharge ports 13 in the circumferential direction and a storage box 85 in the outer circumferential direction;

[0161] Each second discharge port 13 is connected between the storage box 85 and the upper end face of the support plate 20. The fixed body 10 is provided with a discharge plate 83 that can move up and down and open and close the second discharge port 13.

[0162] The support plate 20 is provided with a angular material feeding plate 84 on its periphery;

[0163] The storage bin 85 is equipped with a filter screen that can filter insect slurry.

[0164] Specifically, the fixing body 10 may be provided with a slot 14 corresponding to and communicating with the second discharge port 13 in the circumferential direction; the slot 14 is arranged vertically, and the discharge plate 83 can be inserted into the slot 14 and open and close the second discharge port 13; the discharge plate 83 can directly open and close the second discharge port 13 through the lower end, but the sealing is not good and it is easy to cause the insect slurry to overflow; preferably, the lower part of the discharge plate 83 is provided with a second discharge port 831, and a sliding sealing ring is provided on the outer periphery of the second discharge port 831, and the sliding sealing ring is located between the discharge plate 83 and the slot 14;

[0165] In the initial state, the discharge plate 83 located in the slot 14 closes the second discharge port 13, that is, the second discharge port 831 and the second discharge port 13 are staggered; and the support plate 20 rotates at a certain speed, which can prevent the larvae from being deflected by centrifugal force.

[0166] After the larvae undergo one cycle of compaction, needle piercing, squeezing, and feeding, the rotation speed of the support plate 20 increases. Under the action of centrifugal force, the larvae shells and larvae paste move outward and approach the periphery of the cavity. The discharge plate 83 moves up and down, so that when the second discharge port 831 aligns with the second discharge port 13, the larvae paste and larvae shells are discharged from the second discharge port 13 to the storage box 85. The filter screen in the storage box 85 can separate the larvae shells and larvae paste. In addition, the support plate 20 is provided with an angular feeding plate 84, which can feed the larvae paste and larvae shells that are not located at the second discharge port 13 to the second discharge port 13.

[0167] In some examples of the present invention, such as Figure 14 As shown, the axis of the first needle wheel 51 is arranged at an angle to the upper surface of the support plate 20;

[0168] Along the axis of the first needle wheel 51, from the inside out, the needle wheel assembly 50 gradually approaches the upper surface of the support plate 20.

[0169] Specifically, the first needle wheel 51 is arranged at an angle, or the upper surface of the support plate 20 is arranged at an angle, so that the two are at an angle to each other;

[0170] As the rotation speed of the support plate 20 gradually increases, the larvae are moved from the inside to the outside by centrifugal force, that is, they gradually move away from the center of the support plate 20. During the movement of the larvae, the needle wheel assembly 50 gradually approaches the upper surface of the support plate 20. The first protrusion 511 on the first needle wheel 51 acts on the larvae, which can gradually pierce the larvae to different depths, avoiding the problem that some larvae cannot be completely pierced due to differences in larval size.

[0171] The method of using this black soldier fly larvae shell pulp separation and processing device specifically includes the following steps:

[0172] S1, the first pressing wheel 71, the needle wheel assembly 50, the second pressing wheel 72, and the feeding roller 60 are arranged sequentially on the corresponding support slider 43, and the arrangement direction is consistent with the rotation direction of the support plate 20.

[0173] The support plate 20 is driven to rotate circumferentially;

[0174] S2, black soldier fly larvae fall from the feed inlet 91 onto the support plate 20 and rotate with it;

[0175] The larvae first pass through the first compaction wheel 71: the rotating first compaction wheel 71 first compacts the larvae to reduce the gaps between them;

[0176] After being compacted, the larvae pass through the needle wheel assembly 50: the first needle wheel 51 rotates, and the first protrusion 511 on it acts as a needle on the larvae, so that certain holes are formed on the surface of the larvae so that the insect paste can flow out; the larvae attached to the first protrusion 511 follow the rotation and are blocked by the second protrusion 524 to detach and complete the "feeding" process, so that the attached larvae fall back onto the support plate 20.

[0177] After being pierced, the larvae pass through the second compression wheel 72: the rotating second compression wheel 72 squeezes the larvae, causing the insect paste to flow out or burst out from the larvae's piercing hole first, reducing the damage to the insect shell caused by direct crushing.

[0178] After being squeezed, the larvae then pass through the feeding roller 60: the feeding roller 60 is driven to rotate, which can initially separate the tightly stuck larvae and adjust their position.

[0179] After being fed, the larvae continue to pass through the first pressing wheel 71 to complete one cycle.

[0180] S3, during the rotation of the support plate 20, the rotary plate 30 will drive the first pressing wheel 71, the needle wheel assembly 50, the second pressing wheel 72, and the feeding roller 60 to reciprocate around the center of the rotary plate 30 within a certain angle, repeatedly compacting, piercing, squeezing, and feeding the larvae on the support plate 20 to improve the shell-slurry separation effect.

[0181] S4. After squeezing or at least one cycle, the insect shells and insect pulp on the support plate 20 will be collected or further separated.

[0182] The foregoing description, with reference to preferred embodiments, details an exemplary embodiment of the black soldier fly larvae shell pulp separation and processing device proposed in this invention. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention without exceeding the protection scope of this invention, which is determined by the appended claims.
