Description

Technical Field

[0001] The present invention relates to the technology of separating shell from pulp, belonging to the field of insect processing, and specifically relates to a device for separating shell from pulp of black soldier fly larvae and its usage method. Background Art

[0002] As a saprophagous insect of the family Stratiomyidae, the black soldier fly can feed on livestock and poultry manure and domestic waste, and has the characteristics of rapid reproduction, large biomass, wide food habits, high absorption and conversion rate, and low feeding cost. Its larvae are rich in protein and fat and are a high-quality feed source. For example, the main nutritional components in the dry matter of black soldier fly larvae (BSFL) include crude protein, crude fat, calcium, phosphorus, chitin, etc., and have great potential in replacing fish meal and reducing carbon emissions in the aquaculture industry;

[0003] In the process of processing black soldier fly larvae, it is necessary to separate the larval shell from the pulp. That is, the shell contains chitin that can promote animal intestinal health and enhance immunity 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 pulp ice particles containing fine chitin are especially suitable for aquatic feeds for fish, shrimps and crabs;

[0004] Black soldier fly larvae need to be washed and steamed first and then enter the shell-pulp separation process. In the shell-pulp separation and processing, the traditional method is mechanical pressing, that is, the roller squeezes the black soldier fly larvae to make them burst, and then the shell and the slurry are separated. This method has the following problems: 1. The black soldier fly larvae themselves have high toughness, elasticity and strength. During the bursting process, it is easy for the black soldier fly larvae to deform and cannot be guaranteed to burst completely, reducing the effect of shell-pulp separation; 2. Direct extrusion and bursting easily damage the shell. That is, after the shell is under pressure, the first damaged position is often the weak part on the surface of the shell. Not only the bursting position cannot be controlled, but also obvious defects are likely to appear at the bursting notch of the shell; 3. After being squeezed, the internal pressure of the black soldier fly larvae is relatively large, and it is easy to cause the splashing of the pulp. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for separating shell from pulp of black soldier fly larvae, which not only realizes the acupuncture effect on the black soldier fly larvae so that the pulp flows out, and avoids a large number of larvae adhering to affect the acupuncture effect, but also makes the pulp flow out or burst out from the puncture holes of the larvae first, reduces the damage to the shell caused by direct bursting, avoids the splashing of the pulp after the larvae are pressed, and realizes repeated acupuncture and extrusion of the larvae on the support plate to improve the effect of shell-pulp separation.

[0027] One end of the first pinion and the second pinion is respectively connected to a pair of slave gears.

[0028] In some examples of the present invention, the first convex body and the second convex body have the same structure, and are both arranged circumferentially first and then axially spaced;

[0029] A pair of slave gears are rotatably mounted on the adjusting disk, and the adjusting disk is rotatably mounted on the gear shaft;

[0030] A positioning member is provided on the support cover;

[0031] One end of the positioning member can act on the adjusting disk to lock and fix the two extreme positions of the rotation of the adjusting disk;

[0046] Along the axis of the first pinwheel and in the direction from the inside to the outside, the lower part of the pinwheel assembly gradually approaches the upper end surface of the support disk.

[0047] The purpose of the present invention is also to provide a method for using a black soldier fly larva shell-pulp separation and processing device. The black soldier fly larvae are successively compacted by the first pressing wheel to reduce the gap between the larvae, pricked by the pinwheel assembly so that the insect pulp flows out, extruded by the second pressing wheel so that the insect pulp preferentially flows out or explodes from the puncture holes of the larvae, and the position of the larvae is adjusted by the material distributing roller, which can effectively increase the number of pricks on the larvae and the extrusion effect, reduce the damage to the insect shells caused by direct crushing, avoid the splashing of the insect pulp after the larvae are pressed, and improve the effect of shell-pulp separation.

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

[0049] S1, the first pressing wheel, the pinwheel assembly, the second pressing wheel, and the material distributing roller are successively arranged on the corresponding support sliders, and the arrangement direction is the same as the rotation direction of the support disk;

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

[0051] S2, the black soldier fly larvae fall on the support disk from the feed port and rotate with it;

[0052] The larvae first pass through the first pressing wheel: the rotating first pressing wheel first compacts the larvae to reduce the gap between the larvae;

[0053] The compacted larvae then pass through the pinwheel assembly: the first pinwheel rotates, and the first convex bodies thereon act on the larvae with needles, causing certain punctures on the surface of the larvae so that the larval juice can flow out; the larvae attached to the first convex bodies rotate along with it and are blocked and separated by the second convex bodies to complete the "feeding" process, causing the attached larvae to fall back onto the support plate again;

[0054] The larvae after being needled then pass through the second pressing wheel: the rotating second pressing wheel squeezes the larvae, causing the larval juice to flow out or burst out preferentially from the punctures of the larvae, reducing the damage to the insect shell caused by directly pressing and bursting;

[0055] The larvae after being squeezed then pass through the feeding roller: the feeding roller is driven to rotate, and can initially separate the closely adhered and sticky larvae and adjust their positions;

[0056] The larvae after being fed continue to pass through the first pressing wheel to complete one cycle of circulation;

[0057] S3. During the rotation of the support plate, the rotary disk will drive the first pressing wheel, the pinwheel assembly, the second pressing wheel, and the feeding roller to rotate reciprocally around the center of the rotary disk within a certain angle, repeatedly compacting, needling, squeezing, and feeding the larvae on the support plate to improve the effect of shell-juice separation;

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

[0059] Compared with the prior art, in this black soldier fly larvae shell-juice separation and processing device, by setting the pinwheel assembly and the pressing wheels, when the support plate drives multiple larvae to pass through the pinwheel assembly, on the one hand, it needles the larvae so that the larval juice can flow out, and on the other hand, it causes the attached larvae to be blocked and separated by the second convex bodies to complete the "feeding" process, avoiding a large number of larvae from attaching and affecting the needling of other larvae. When the needled larvae pass through the pressing wheels, the pressing wheels squeeze the larvae, causing the larval juice to flow out or burst out preferentially from the punctures of the larvae, reducing the damage to the insect shell caused by directly pressing and bursting, and avoiding the larval juice from splashing due to the larvae being directly subjected to a large extrusion force; in addition, during the rotation of the support plate, the rotary disk will drive the pinwheel assembly and the pressing wheels to rotate reciprocally synchronously, realizing repeated needling and squeezing of the larvae on the support plate to improve the effect of shell-juice separation;

[0060] Due to the setting of the feeding roller, and the first pressing wheel, the pinwheel assembly, the second pressing wheel, and the feeding roller are arranged in sequence on the corresponding support sliders, completing the sequential actions of compacting, needling, squeezing, and feeding adjustment of the larvae. After one cycle of circulation, the larvae can be compacted again, etc., and it is possible to effectively increase the number of needlings and the squeezing effect on the larvae by changing the different positions of the larvae;

[0061] Since the first pinion and the second pinion rotate in the same direction through the drive assembly, the corresponding feeding impact effect can be increased. In one way, a pair of driven gears are rotatably installed on the adjusting disk, and the adjusting disk can be locked and fixed at two limit positions of rotation. Therefore, without affecting the same-direction rotation of the first pinion and the second pinion, the position switching between the first pinion and the second pinion is realized, and the corresponding pinion is used for feeding processing, avoiding the wear of the first convex body or the second convex body during long-term use and being unable to effectively puncture the larvae; in another way, one end of the second pinion is connected to the driven gear by a keyway, and the column body is provided with a circumferential closed-loop and axially offset chute, so that the second pinion moves axially while rotating, avoiding excessive gaps and missed feeding, and effectively improving the feeding effect;

[0062] The larvae after extrusion or feeding can be discharged from the middle or the periphery of the support disk; when the larvae are discharged from the periphery, along the axis of the first pinion and from the inside to the outside, the lower part of the pinion assembly gradually approaches the upper end surface of the support disk. After the rotation speed of the support disk gradually increases, the larvae move from the inside to the outside under the centrifugal force, and the first convex body can gradually puncture the larvae at different depths, avoiding the problem that some larvae cannot be completely punctured due to the difference in larva size.

[0088] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 shown, a black soldier fly larva shell pulp separation and processing device of the present invention includes:

[0089] A fixed body 10, a support disk 20, and a rotary disk 30 arranged coaxially;

[0090] The fixed body 10 has a cavity, and a feed port 91 is provided above the cavity; the support disk 20 is driven to rotate and is located inside the cavity; the rotary disk 30 is driven to reciprocate within a certain angle, and a plurality of support sliders 43 that are elastically downward and can approach and move away from the rotary disk 30 are provided on the circumferential side;

[0091] A pinwheel assembly 50 and a pressure wheel 70 are respectively installed on the support sliders 43, arranged radially, and located above the support disk 20;

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

[0093] The first pinwheel 51 is close to the upper end surface of the support disk 20, and the axis of the first pinwheel 51 is lower than the axis of the second pinwheel 52; a plurality of first convex bodies 511 capable of acting on the larvae by acupuncture are provided on the first pinwheel 51, and the first convex bodies 511 are arranged circumferentially first and then axially at intervals; a plurality of second convex bodies 524 arranged axially at intervals are provided on the second pinwheel 52;

[0094] The first convex body 511 and the second convex body 524 are staggered axially and close to the corresponding pinwheel;

[0095] Among them, the feed inlet 91, the pinwheel assembly 50, and the pressure wheel 70 are arranged in sequence, and the arrangement direction is the same as the rotation direction of the support disk 20;

[0096] Specifically, the fixed body 10 is fixedly arranged and is an integral support structure. The support disk 20 and the rotary disk 30 can be assembled with the fixed body 10 through bearings or slewing bearings respectively; the cavity of the fixed body 10 is cylindrical and has an open upper end structure, and can be closed by a cover plate 90;

[0097] The support disk 20 is driven to rotate, for example, counterclockwise. That is, a driving wheel is provided at the lower end extension of the support disk 20, and the driving member drives the driving wheel to realize the rotation of the support disk 20; the support disk 20 is rotationally sealed with the inner wall of the cavity to prevent the insect shell or insect slurry from overflowing therefrom;

[0098] The rotary disk 30 is driven to rotate reciprocally, for example, reciprocally rotate between 0-60°. As an embodiment of the reciprocating rotation, a main gear can be provided at the lower end of the rotary disk 30. The slidably arranged rack is meshed with the main gear. The rack is installed on the slider, and the slider is the slider of the crank-slider mechanism to move reciprocally, thereby driving the main gear and the rotary disk 30 to rotate reciprocally within a certain angle; as another embodiment, a main gear driven by a motor can be provided at the lower end of the rotary disk 30. An identifier is provided on the rotary disk 30. The fixedly arranged photoelectric sensor can be matched with the identifier. After the main gear drives the rotary disk 30 to rotate a certain angle forward, the photoelectric sensor and the identifier are mutually matched, and then the main gear drives the rotary disk 30 to rotate a certain angle backward; as shown in Figure 1 、 Figure 4 As shown, a plurality of strip-shaped grooves 11 can be provided on the fixed body 10, which can facilitate one end of the pinwheel assembly 50 and the pressure wheel 70 to pass through the fixed body 10 and be rotationally connected with the support slider 43. Further, as shown in Figure 8 As shown, an elastic membrane 12 is provided between the strip-shaped groove 11 and the pinwheel assembly 50 and the pressure wheel 70, which can ensure sealing when the pinwheel assembly 50 and the pressure wheel 70 rotate reciprocally and prevent the insect slurry from splashing out; it should be noted that the elastic membrane 12 can be a folding baffle or a flexible plastic film;

[0099] The support slider 43 is installed on the rotary disk 30 through a fixing plate 44 and is located outside the fixed body 10;

[0100] The pinwheel assembly 50 is used for puncturing the larvae to facilitate the discharge of the insect pulp from the puncture holes. The first pinwheel 51 is driven to rotate, and the second pinwheel 52 can rotate in the same direction or remain stationary. Preferably, it rotates in the same direction. The first convex body 511 and the second convex body 524 can be in the shape of a needle or an irregular angular structure. The first convex body 511 can puncture the larvae, and the second convex body 524 can feed the attached larvae. In the circumferential direction, the first convex bodies 511 need to be arranged more closely. In the axial direction, the first convex bodies 511 and the second convex bodies 524 are arranged at intervals and can intersect with each other. For example, Figure 10 As shown, in the axial direction, the second convex body 524 is located between adjacent first convex bodies 511 and is close to the first pinwheel 51.

[0101] The pressing wheel 70 is rotatably installed on the support slider 43 and can be driven to rotate for squeezing the larvae.

[0102] When this black soldier fly larva shell-pulp separation and processing device is in use, the feed inlet 91, the pinwheel assembly 50, and the pressing wheel 70 are arranged counterclockwise in sequence. At this time, the support disk 20 is driven to rotate counterclockwise, and both the pinwheel assembly 50 and the pressing wheel 70 are close to the support disk 20.

[0103] The black soldier fly larvae enter from the feed inlet 91 onto the support disk 20 in the cavity. It should be noted that the feed inlet 91 can be in a long strip structure and can be provided with a uniform distribution mechanism to ensure that the larvae are laid flat on the support disk 20.

[0104] The support disk 20 drives multiple larvae to first pass through the pinwheel assembly 50. That is, the first pinwheel 51 close to the support disk 20 rotates, and the first convex body 511 thereon punctures the larvae, causing certain puncture holes to form on the surface of the larvae for the insect pulp to flow out. After the first pinwheel 51 rolls and punctures, some larvae will attach to the first convex body 511. The second convex body 524 on the second pinwheel 52 intersects with the first convex body 511 on the first pinwheel 51. The larvae attached to the first convex body 511 rotate and are blocked by the second convex body 524 and fall off to complete the "feeding" process, so that the attached larvae fall back onto the support disk 20 again, preventing a large number of larvae from attaching to the first pinwheel 51 and affecting the puncturing of other larvae.

[0105] The punctured larvae continue to rotate on the support disk 20 and pass through the pressing wheel 70. The pressing wheel 70 squeezes the larvae, causing the insect pulp to flow out or burst out preferentially from the puncture holes of the larvae, reducing the damage to the insect shell caused by direct pressing and avoiding the splashing of the insect pulp due to the larvae being directly subjected to greater extrusion. During the rotation of the support disk 20, the rotary disk 30 rotates. That is, the rotary disk 30 drives the pinwheel assembly 50 and the pressing wheel 70 to rotate reciprocally around the center of the rotary disk 30 synchronously. Its rotation cooperates with the rotation of the support disk 20 to repeatedly puncture and squeeze the larvae on the support disk 20, improving the effect of shell-pulp separation.

[0106] The larvae can be squeezed to form shells and pulp, which can then be collected and further separated;

[0107] During the process of acupuncture by the needle wheel assembly 50 and extrusion by the pressure wheel 70, the needle wheel assembly 50 and the pressure wheel 70 are correspondingly installed on the support slider 43. The support slider 43 is subjected to a downward elastic force, so that the needle wheel assembly 50 and the pressure wheel 70 can have a certain fit with the support disk 20. When encountering larvae with higher hardness or serious stacking, the support slider 43 can move upward away from the support disk 20, that is, the needle wheel assembly 50 or the pressure wheel 70 appropriately moves upward to avoid the corresponding larvae, thereby effectively protecting the needle wheel assembly 50 or the pressure wheel 70.

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

[0109] The pressing wheels 70 are a pair, namely a first pressing wheel 71 and a second pressing wheel 72; the first pressing wheel 71, the pinwheel assembly 50, the second pressing wheel 72, and the material-discharging roller 60 are sequentially arranged on the corresponding supporting slider 43, and the arrangement direction is consistent with the rotation direction of the supporting disk 20;

[0110] The height from the horizontal section below the first pressing wheel 71 to the support plate 20 is higher than the height from the horizontal section below the second pressing wheel 72 to the support plate 20;

[0111] The feed inlet 91 is close to the first pinch wheel 71;

[0112] Specifically, the material-moving roller 60 may be provided with a brush to facilitate the moving of the larvae, one end of which may be mounted on the support slider 43 through a bearing and extend outwardly to be connected to a driving member, and the driving member drives the material-moving roller 60 to rotate;

[0113] The support plate 20 can be divided into four areas ABCD, and there are four support sliders 43, which are circumferentially arranged in the four areas ABCD. At this time, the first clamping wheel 71, the pinwheel assembly 50, the second clamping wheel 72, and the material-discharging roller 60 are connected to the support slider 43 and can reciprocate synchronously, that is, the first clamping wheel 71 is located in the area A, ..., and the material-discharging roller 60 is located in the area D;

[0114] The first pressing wheel 71 can be structurally identical to the second pressing wheel 72, except that the mounting height of the first pressing wheel 71 is slightly higher than that of the second pressing wheel 72. The larvae enter the A area from the feed inlet 91. The first pressing wheel 71 is used to preliminarily compact the larvae after feeding to reduce the gaps between the larvae, facilitating the needle wheel assembly 50 to perform the needle piercing action on the overlapping larvae.

[0115] The compacted larvae enter the B area, where the needle wheel assembly 50 performs needle piercing treatment on the larvae. Then, the larvae after needle piercing enter the C area, and the second pressing wheel 72 performs extrusion treatment on the larvae, causing the insect pulp to separate from the insect shell. The larvae after extrusion will be closely adhered together and then enter the D area.

[0116] The feeding roller 60 in the D area is driven to rotate. The feeding roller 60 can preliminarily separate the closely adhered larvae and adjust their positions to complete one cycle.

[0117] When collecting the insect shell and insect pulp, the larvae complete at least one cycle. That is, the larvae whose positions are changed after being separated by the feeding roller 60 will re-enter the A area for compaction and then enter the B area for needle piercing treatment. Since the positions of the larvae after cycling are changed, the needle wheel assembly 50 in the B area can perform needle piercing treatment on different positions of the larvae, and the C area continues to extrude the larvae after needle piercing. Therefore, the number of needle piercings on the larvae is effectively increased, improving the effect of shell-pulp separation.

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

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

[0120] The adjusting rod 41 is threadedly mounted on the fixed plate 44, and the first elastic member 42 is connected to the lower rod shoulder of the adjusting rod 41 and the support slider 43.

[0121] The limiting cylinder 45 is vertically adjusted and mounted at the lower end of the support slider 43.

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

[0123] When this example is initially used, the position of the limiting cylinder 45 can be adjusted to limit the extreme position of the downward movement of the support slider 43. For example, as Figure 5 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 to achieve vertical adjustment.

[0124] After the position of the limit cylinder 45 is determined, rotate the adjusting rod 41 to move the adjusting rod 41 up and down. Since a first elastic member 42 is provided between the rod shoulder of the adjusting rod 41 and the support slider 43, and the lower end of the support slider 43 contacts the limit cylinder 45 for limiting, the adjustment of the force exerted on the support slider 43 by the first elastic member 42 is realized to be applicable to the processes of compacting, needling, squeezing, and feeding the larvae.

[0125] It should be noted that the position of the limit cylinder 45 can be adjusted to change the position of the support slider 43, so as to realize the adjustment of the heights of the first pressing wheel 71 and the second pressing wheel 72 to complete the corresponding compacting and squeezing processes.

[0126] In some examples of the present invention, as Figure 5 、 Figure 6 、 Figure 7 shown, the first pinwheel 51 and the second pinwheel 52 rotate in the same direction through a driving assembly;

[0127] The driving assembly has a gear shaft 53 and a pair of driven gears 54 located inside the support cover 47;

[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 be connected to a driving member, and the gear ends are respectively meshed and connected to a pair of driven gears 54;

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

[0131] Specifically, when the second pinwheel 52 is in a fixed state, the impact of the second convex body 524 on the first convex body 511 on the first pinwheel 51 is small, and the material feeding effect is reduced. For example, there is a problem that some larvae "spin" on the first convex body 511; therefore, the first pinwheel 51 and the second pinwheel 52 rotate in the same direction to increase the corresponding material feeding impact effect;

[0132] The support cover 47 is a closed structure and is connected to the support slider 43 through a sleeve. The shaft end of the gear shaft 53 passes through the sleeve, is rotationally connected to the support slider 43 through a bearing, and extends to the outside to be connected to a driving member;

[0133] The driving member can be a motor, a first gear connected to the output end of the motor, and a second gear fixed on the side of the gear shaft 53. The first gear is meshed and connected to the second gear. That is, after the motor is started, the rotation of the gear shaft 53 is realized through the meshing of the first gear and the second gear, and the gear shaft 53 is respectively meshed and connected to a pair of driven gears 54, so that the pair of driven gears 54 rotate in the same direction to complete the co-rotation of the corresponding connected first pinwheel 51 and second pinwheel 52.

[0134] In some examples of the present invention, as Figure 5 , Figure 6 , Figure 7 shown, the first convex body 511 and the second convex body 524 have the same structure, and are both arranged circumferentially first and then axially spaced;

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

[0136] A positioning member 48 is provided on the support cover 47;

[0137] One end of the positioning member 48 can act on the adjusting disk 55 to lock and fix the two extreme positions of the rotation of the adjusting disk 55;

[0138] When the adjusting disk 55 rotates to the first extreme position, the first pinion 51 is close to the upper end surface of the support disk 20, and the second pinion 52 is relatively far from the upper end surface of the support disk 20; when the adjusting disk 55 rotates to the second extreme position, the second pinion 52 is close to the upper end surface of the support disk 20, and the first pinion 51 is relatively far from the upper end surface of the support disk 20;

[0139] Specifically, the positioning member 48 can be a positioning rod structure, that is, an arc-shaped groove is provided on the support cover 47, the rod body of the positioning member 48 is threadedly installed on the adjusting disk 55 and can slide in the arc-shaped groove, and the rod head contacts the support cover 47; when the adjusting disk 55 is locked and fixed, the positioning member 48 rotates so that the rod head contacts the support cover 47 for locking and fixing, and when the adjusting disk 55 is adjusted in angle, the positioning member 48 rotates in the reverse direction and slides in the arc-shaped groove;

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

[0141] The adjusting disk 55 rotates around the center of the gear shaft 53 and rotates within a certain angle range. The two extreme positions of this angle can make the positions of the first pinion 51 and the second pinion 52 be mirror-inverted, that is, the first extreme position is the initial state. The first pinion 51 performs acupuncture treatment on the larvae on the support disk 20, and the second pinion 52 that rotates in the same direction performs feeding treatment on the larvae attached to the first pinion 51, avoiding a large number of larvae attaching to the first pinion 51 and affecting the acupuncture of other larvae;

[0142] When the first convex body 511 on the first pinwheel 51 is worn out after long-term use and cannot effectively puncture the larvae, the adjustment disc 55 rotates and switches from the first extreme position to the second extreme position. At this time, the second pinwheel 52 punctures the larvae on the support disc 20, and the first pinwheel 51 rotating in the same direction feeds the larvae attached to the second pinwheel 52, preventing a large number of larvae from attaching to the second pinwheel 52 and affecting the puncture of other larvae.

[0143] It should be noted that while the adjustment disc 55 rotates, a pair of slave gears 54 rotate around the gear shaft 53 accordingly. Therefore, without affecting the co-rotation of the first pinwheel 51 and the second pinwheel 52, the position switching between the first pinwheel 51 and the second pinwheel 52 is achieved, and the corresponding pinwheel performs the feeding process, preventing the first convex body 511 or the second convex body 524 from being worn out after long-term use and unable to effectively puncture the larvae.

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

[0145] One end of the second pinwheel 52 is connected to the slave gear 54 by a key and is provided with a cylinder 521; the cylinder 521 is provided with a circumferentially closed and axially offset chute;

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

[0147] When the slave gear 54 rotates and the limiting rod 522 slides within the chute, the second pinwheel 52 axially reciprocates to enable the second convex body 524 thereon to axially move between adjacent first convex bodies 511 on the first pinwheel 51;

[0148] Specifically, axially, although the first convex body 511 and the second convex body 524 are staggered, there is still a certain gap. Since the size of the larvae themselves is not large, there is a problem that the second convex body 524 cannot block and separate for feeding, that is, the larvae still adhere to the first convex body 511 and are located in the gap and cannot be fed;

[0149] The second pinion 52 can be connected to the corresponding driven gear 54 by means of splines or flat keys to ensure that the second pinion 52 can move axially while rotating circumferentially; while the first pinion 51 can be normally connected to the driven gear 54, that is, the first pinion 51 only rotates and does not move axially; the cylinder 521 is coaxially fixed on the second pinion 52 and is provided with a circumferentially closed chute; the limiting rod 522 on the support cover 47 can be elastically biased towards the cylinder 521, that is, the limiting rod 522 is slidably arranged and sleeved with a second elastic member 523. One end of the second elastic member 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 member 523, one end of the limiting rod 522 is elastically embedded in the chute; the second pinion 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 pinion 52 to rotate through the key. The limiting rod 522 slides in the chute and the chute has an axial offset, so that the second pinion 52 moves axially while rotating. The moving stroke is slightly smaller than the distance between the first convex bodies 511 adjacent axially, that is, the first convex body 511 on one side close to the second convex body 524 feeds the material, and then moves axially to approach the second convex body 524 on the other side to feed the material, avoiding missing the material due to too large a gap and effectively improving the feeding effect.

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

[0152] When discharging from the middle of the support plate 20, as Figure 11 、 Figure 12 shown, a discharge tube 82 and a discharge tube 81 are arranged coaxially and from inside to outside in the middle of the cavity;

[0153] The discharge tube 81 is fixedly arranged and is provided with a first discharge port 811 that can be butt-jointed with the upper end face of the support plate 20; the discharge tube 82 rotates relative to the discharge tube 81, and the upper part is provided with a first discharge port 821 and a plurality of first through holes 822 that can be butt-jointed with the first discharge port 811;

[0154] Among them, the first discharge port 811 is close to the second pressing wheel 72 or the feeding roller 60, and a guide plate 93 that moves up and down is arranged above the first discharge port 811;

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

[0156] Specifically, the discharge tube 81 is rotationally sealed with the support plate 20 and is provided with a first discharge port 811 in the C area or the D area, that is, the first discharge port 811 discharges the larvae after being squeezed or fed;

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

[0158] When the larvae are being compacted, needled, and extruded, the material guiding plate 93 moves away from the support plate 20; when the next cycle starts or after extrusion and discharging, the material guiding plate 93 moves downward so that its lower end fits with the upper end of the support plate 20, and the support plate 20 continues to rotate. Through the material guiding process of the material guiding plate 93, the larvae move inward along the material guiding plate 93.

[0159] Initially, the discharge cylinder 82 closes the first discharge port 811, that is, the first discharge port 821 and the first through hole 822 on the discharge cylinder 82 are staggered from the first discharge port 811 on the discharge cylinder 81, and the larvae cannot be discharged from the first discharge port 821; when slurry discharge treatment is required, the discharge cylinder 82 is rotated so that the multiple first through holes 822 on the discharge cylinder 82 are aligned with the first discharge port 811, and the insect slurry will be discharged from the first discharge port 811 and the first through hole 822; when both the insect shell and the insect slurry are discharged, the discharge cylinder 82 is rotated so that the first discharge port 821 on the discharge cylinder 82 is aligned with the first discharge port 811, and the insect shell and the insect slurry will be jointly discharged from the first discharge port 811 and the first discharge port 821.

[0160] When discharging from the circumferential side of the support plate 20, as Figure 13 、 Figure 14 shown, a plurality of second discharge ports 13 are provided in the circumferential direction of the fixed body 10, and a storage box 85 is provided on the circumferential outer side;

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

[0162] A material shifting plate 84 with an angular structure is provided on the circumferential side of the support plate 20;

[0163] Among them, a filter screen capable of filtering the insect slurry is provided in the storage box 85.

[0164] Specifically, a slot hole 14 corresponding to and communicating with the second discharge port 13 may be provided in the circumferential direction of the fixing body 10; the slot hole 14 is vertically arranged, and the discharge plate 83 can be inserted into the slot hole 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 performance is not good, and it is easy to cause the worm pulp to overflow; preferably, a second discharge port 831 is provided at the lower part of the discharge plate 83, and a sliding sealing ring is provided on the outer peripheral side of the second discharge port 831, and the sliding sealing ring is located between the discharge plate 83 and the slot hole 14;

[0165] In the initial state, the discharge plate 83 located in the slot hole 14 closes the second discharge port 13, that is, the second discharge port 831 and the second discharge port 13 are arranged in a staggered manner; and the support disk 20 rotates at a certain speed, and this speed can prevent the larvae from shifting due to centrifugal force;

[0166] After the larvae undergo a one-cycle circulation of compaction, acupuncture, extrusion, and material dialing, the rotation speed of the support disk 20 increases. Under the action of centrifugal force, the worm shell and the worm pulp move outward and approach the circumferential side wall of the cavity. When the discharge plate 83 moves up and down so that the second discharge port 831 is docked with the second discharge port 13, the worm pulp and the worm shell are discharged from the second discharge port 13 to the storage box 85, and the filter screen in the storage box 85 can separate the worm shell and the worm pulp; in addition, a dialing plate 84 with an angular structure is provided on the support disk 20, which can dial the worm pulp and worm shell not located at the second discharge port 13 to the second discharge port 13.

[0167] In some examples of the present invention, as Figure 14 shown, the axis of the first pinwheel 51 is arranged at an angle with the upper end surface of the support disk 20;

[0168] Along the axis of the first pinwheel 51 and from the inside to the outside, the lower part of the pinwheel assembly 50 gradually approaches the upper end surface of the support disk 20;

[0169] Specifically, the first pinwheel 51 is arranged obliquely or the upper end surface of the support disk 20 is arranged obliquely so that the two are at an angle to each other;

[0170] When the rotation speed of the support disk 20 gradually increases, the larvae move outward gradually under the action of centrifugal force, that is, gradually away from the center of the support disk 20. During the movement of the larvae, the lower part of the pinwheel assembly 50 gradually approaches the upper end surface of the support disk 20, and the first convex body 511 on the first pinwheel 51 acts on the larvae, and can gradually acupuncture the larvae at different depths, avoiding the problem that some larvae cannot be completely acupuncture due to the difference in the size of the larvae.

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

[0172] S1. The first pressing wheel 71, the pinwheel assembly 50, the second pressing wheel 72, and the material feeding roller 60 are arranged in sequence on the corresponding supporting sliders 43, and the arrangement direction is the same as the rotation direction of the supporting disk 20.

[0173] The supporting disk 20 is driven to rotate circumferentially.

[0174] S2. The black soldier fly larvae fall onto the supporting disk 20 from the feeding port 91 and rotate with it.

[0175] The larvae first pass through the first pressing wheel 71: The rotating first pressing wheel 71 first compacts the larvae to reduce the gaps between the larvae.

[0176] The compacted larvae then pass through the pinwheel assembly 50: The first pinwheel 51 rotates, and the first convex bodies 511 on it act on the larvae with needles, so that certain puncture holes are formed on the surface of the larvae for the larval juice to flow out; the larvae attached to the first convex bodies 511 rotate and are blocked by the second convex bodies 524 and separated to complete the "material feeding" process, so that the attached larvae fall back onto the supporting disk 20 again.

[0177] The punctured larvae then pass through the second pressing wheel 72: The rotating second pressing wheel 72 squeezes the larvae, so that the larval juice preferentially flows out or explodes from the puncture holes of the larvae, reducing the damage to the insect shell caused by direct squeezing.

[0178] The squeezed larvae then pass through the material feeding roller 60: The material feeding roller 60 is driven to rotate, and can initially separate the closely adhered and sticky larvae and adjust their positions.

[0179] The larvae after material feeding continue to pass through the first pressing wheel 71 to complete a cycle.

[0180] S3. During the rotation of the supporting disk 20, the rotary disk 30 will drive the first pressing wheel 71, the pinwheel assembly 50, the second pressing wheel 72, and the material feeding roller 60 to rotate reciprocally around the center of the rotary disk 30 within a certain angle synchronously, and repeatedly compact, puncture, squeeze, and feed the larvae on the supporting disk 20 to improve the effect of shell-juice separation.

[0181] S4. After the squeezing process or after at least one cycle, the insect shells and larval juice on the supporting disk 20 will be collected or further separated.

[0182] In the above, a demonstration implementation manner of a black soldier fly larvae shell-juice separation processing device proposed by the present invention is described in detail with reference to preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present invention, various modifications and improvements can be made to the above specific embodiments, and various combinations can be made to the various technical features and structures proposed by the present invention, without exceeding the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.

A method for using the black soldier fly larvae shell pulp separation and processing device according to claim 2, characterized in that: The specific steps include: S1, the first pressing wheel (71), the pin wheel assembly (50), the second pressing wheel (72), and the material-discharging roller (60) are sequentially arranged on the corresponding supporting slider (43), and the arrangement direction is consistent with the rotation direction of the supporting disk (20); The support plate (20) is driven to rotate in a circumferential direction; S2, the black soldier fly larvae fall from the feed port (91) onto the support plate (20) and rotate with it; The larvae first pass through the first compacting wheel (71): the rotating first compacting wheel (71) first compacts the larvae to reduce the gaps between the larvae; The compacted larvae then pass through the pinwheel assembly (50): the first pinwheel (51) rotates, and the first protrusion (511) thereon pricks the larvae with a needle, so that certain puncture holes are formed on the surface of the larvae so that the larvae slurry can flow out; the larvae attached to the first protrusion (511) follow the rotation and are blocked by the second protrusion (524) to break away, thus completing the "beating" process, so that the attached larvae fall back onto the support plate (20); The larvae after being pricked by needles then pass through the second pressing wheel (72): the rotating second pressing wheel (72) squeezes the larvae so that the insect pulp flows out or bursts out from the puncture holes of the larvae first, thereby reducing the damage to the insect shell caused by direct pressing and bursting; The squeezed larvae then pass through a material-moving roller (60). The material-moving roller (60) is driven to rotate, and can initially move apart the tightly and sticky larvae and adjust their positions. The larvae after the material is removed continue to pass through the first pressing wheel (71), completing a cycle; S3, during the rotation of the support disk (20), the rotating disk (30) drives the first pressing wheel (71), the pinwheel assembly (50), the second pressing wheel (72), and the material-dispensing roller (60) to synchronously rotate back and forth within a certain angle around the center of the rotating disk (30), and repeatedly compact, acupuncture, squeeze, and dispense the larvae on the support disk (20), so as to improve the effect of shell-slurry separation; S4, after the extrusion process or at least one cycle, the insect shells and insect pulp on the support plate (20) will be collected or further separated.
