TECHNICAL FIELD

[0002] Lepidoptera insects are important pests in forestry. In the process of physiological and biochemical research of insects, artificial feeding of test insect larvae is often required to obtain larvae of different ages, and then the physiological and biochemical changes and ecological characteristics of insect larvae are studied. In the process of feeding general type Lepidoptera larvae, trays are needed to fill feed and egg grains of larvae, and the trays are used for feeding general type Lepidoptera larvae. In the prior art, attempts have been made to transport trays and the like in a semi-mechanical manner, but the efficiency is relatively low, and it still relies heavily on manual work, resulting in high cost and low work efficiency. In addition, the placement of egg grains in the tray needs to consider the small size of the egg grains and the difficulty of being squeezed, and the survival rate needs to be ensured.

[0059] The provided automated propagation system for lepidopteran larvae has the following technical advantages:

[0060] The design of the support components, material separating claws, and material separating paddles enables accurate and efficient separation of the bottom pallet from a stack of pallets, improving operational stability.

[0061] Furthermore, the supporting gap and the peeling gap share the same gap, and the material distribution claws and material distribution pawls, as well as the cylinders that drive their respective actions, are arranged in a one-to-one correspondence. Support components and cylinders for driving the material distribution claws and pawls are arranged around the through-hole, allowing the system to be configured in its simplest way and reducing its space occupation. The PLC controller controls these components to operate automatically and sequentially, greatly improving efficiency.

[0062] Furthermore, the two pallet-holding claws are located below the support platform, allowing the pallet to be positioned closer to the downstream conveyor belt when supporting a stack of pallets. This enables the individual pallets being stripped to fall with the shortest possible distance, preventing the pallets from swaying due to excessive height and failing to fall accurately onto the downstream conveyor belt.

[0063] Furthermore, the transfer pallet plate of the first conveyor line, together with the two lifting plates of the second conveyor line, can smoothly complete the transfer of a stack of pallets from the first conveyor line to the second conveyor line. Moreover, this arrangement is completed within the vertical space of the first and second conveyor belts, without occupying too much external space.

[0064] Furthermore, the setup of three first conveyor lines allows the first first conveyor line to complete the transport of several groups of stacked pallets before the second first conveyor line transports several groups of stacked pallets, and so on, until the third first conveyor line transports them. This setup can significantly extend the automation time for transporting a stack of pallets and reduce the time required to frequently place a stack of pallets on the first conveyor line, allowing operators to free up extra time to do other work.

[0065] Furthermore, the positioning blocks enable precise positioning of the pallet on the downstream conveyor belt, ensuring accurate subsequent filling.

[0066] Furthermore, the egg transport unit is designed to simultaneously transport eggs to three trays arranged sequentially along the upstream and downstream directions on the larvae-collecting conveyor belt, greatly improving efficiency. Moreover, the cooperation of the eight transport units allows for the transport of eggs independently within a relatively small space.

[0067] Furthermore, the storage body is fixedly installed on a plate that can reciprocate under the control of an electromagnet switch. The movement allows the storage body to connect to the feed pipe or the delay pipe. This arrangement allows some extra eggs that are delayed by the signal transmission to be transported to the egg collection body, where they can be collected and reused, thus improving the accuracy of adding a quantitative amount of eggs.

[0068] Furthermore, the buffer configuration enables the simultaneous and temporary storage of a fixed quantity of eggs during the egg delivery process, thus achieving uninterrupted egg delivery.

[0069] Furthermore, the cone-shaped structure, which is vertically positioned at the small-diameter opening of the funnel and whose tip extends into the interior of the funnel, allows the falling eggs to be dispersed, preventing excessive compression that could cause the eggs to die.

[0070] Furthermore, the electrical components of these multiple parts are all electrically connected to the PLC controller, enabling automated control, reducing manual operation, and improving efficiency. Attached Figure Description

[0088] like Figures 1-15 As shown, the present invention provides an automated propagation system for propagating lepidopteran larvae, comprising:

[0089] The pallet peeling section 1 includes a support platform 2 with through-holes 3 extending through its upper and lower sides for individual pallets to drop. It also includes a support component located at the through-holes 3, capable of opening and closing them. When the through-holes 3 are closed, the support component supports a stack of pallets 4; when the through-holes 3 are open, the support component does not support a stack of pallets 4. Between adjacent pallets in the stack, a support gap and a peeling gap extending inward from the side of the entire stack are formed. The bottommost pallet in the stack is the pallet to be dropped. Corresponding to the support gap between the pallet to be dropped and the pallet above it, a corresponding material-distributing claw 5 is arranged, capable of extending into and exiting the support gap. Corresponding to the peeling gap between the pallet to be dropped and the pallet above it, a corresponding material-distributing claw 5 is arranged. The material distribution claw 6 can extend into and out of the peeling gap, and after extending into the peeling gap, it can move downward to peel off the tray to be dropped and move upward to return to its original position. In the initial state: the supporting component closes the through-hole 3 and the supporting component supports a stack of trays 4, the material distribution claw 5 leaves the supporting gap, and the material distribution claw 6 leaves the peeling gap. In the working state: the material distribution claw 5 extends into the supporting gap, the supporting component opens the through-hole 3 so that the supporting component does not support a stack of trays 4, and the material distribution claw 6 extends into the peeling gap and moves downward to peel off the tray to be dropped. In the return state: the material distribution claw 6 moves upward to return to its original position and leaves the peeling gap, the material distribution claw 5 leaves the supporting gap, and the supporting component closes the through-hole 3 to support the remaining part of the stack of trays that has been dropped after the material distribution claw 5 leaves.

[0090] The pallet upstream transfer section is located upstream of the pallet peeling section 1 and is capable of transporting the stack of pallets 4 to the support assembly in its initial state at the through-hole 3;

[0091] The downstream pallet transfer section is located below the support platform 2, corresponding to the through-hole 3, and is capable of transporting the pallet to be dropped.

[0092] A filling section, located above the tray transferred by the downstream transfer section of the tray and having a filling outlet corresponding to the tray, is used to fill the tray with materials for feeding.

[0093] The insect receiving section includes an insect receiving conveyor belt 68 and an egg conveying component located above the insect receiving conveyor belt 68. The insect receiving conveyor belt 68 is located downstream of the tray downstream moving section and is used to transport a tray carrying the material. The egg conveying component is used to transport eggs into the tray carrying the material.

[0094] The arrangement of the support component, the material separating claw 5, and the material separating claw 6 enables accurate and efficient separation of the bottommost pallet from a stack of pallets 4, improving operational stability.

[0095] In one specific implementation, such as Figures 2-4As shown, the through-hole 3 and each of the trays have the same length and width directions. The supporting gap and the peeling gap share the same gap, which is called the shared gap 7. There are 3 shared gaps 7. There are 3 material distribution claws 5 and 3 material distribution paddles 6. Each shared gap 7 corresponds to one material distribution claw 5 and one material distribution paddle 6. The 3 shared gaps 7 are spaced apart between adjacent trays along the length direction. Along the width direction, a material distribution main cylinder 8 is fixed on the support platform 2 on both sides opposite to the through-hole 3. The pistons of the two material distribution main cylinders 8 can reciprocate along the width direction, and their free ends are connected to a first vertical plate 9. At the lower position on one side of each of the two first vertical plates 9, a receiving plate 10 is fixedly installed. Each receiving plate 10 has three spaced-apart material distribution claws 5 that protrude outwards and are perpendicular to the receiving plate 10. At the upper position on one side of each of the two first vertical plates 9, a material distribution cylinder 11 is fixedly installed. The piston of each material distribution cylinder 11 is arranged vertically, and its free end is fixedly connected to an L-shaped plate 12 with an L-shaped cross-sectional area. The long side of the L-shaped plate 12 slides against the outer surface of the receiving plate 10. The long side of the L-shaped plate 12 is located near the middle position of the receiving plate 10. The dimension of the long side of the L-shaped plate 12 along the length direction is smaller than that of the receiving plate 10 along the length direction. The L-shaped plate 12 is sized such that its short side is located above the receiving plate 10 and can move up and down reciprocally with the piston of the material dispensing cylinder 11. The lower end of the long side of the L-shaped plate 12 forms two downward-extending branch plates, both connected to the lower end. These two branch plates are spaced apart along the length direction and have a notch 13 with an open lower end between them. Along the length direction, the three material dispensing claws 5 are sequentially designated as a first material dispensing claw 14, a second material dispensing claw 15, and a third material dispensing claw 16. The second material dispensing claw 15 is located corresponding to the notch 13. The two branch plates are a first branch plate 17 and a second branch plate 18. The first branch plate 17 is located between the first material dispensing claw 14 and the second material dispensing claw 15. Position: The second branch plate 18 is located between the third distributing claw 16 and the second distributing claw 15. The lower end of the first branch plate 17 has an outwardly protruding first horizontal plate 19 perpendicular to the first branch plate 17. A first distributing claw 20 is formed on the side of the first horizontal plate 19 near the first distributing claw 14. The lower end of the second branch plate 18 has an outwardly protruding second horizontal plate 21 perpendicular to the second branch plate 18. A second distributing claw 22 is formed on the side of the second horizontal plate 21 near the second distributing claw 15, and a third distributing claw 23 is formed on the side near the third distributing claw 16. The vertical dimension of the notch 13 is not less than the stroke of the piston of the distributing lower cylinder 11.In the initial state, the first dispensing claw 14 is positioned above the first dispensing claw 20 and the two are in contact; the second dispensing claw 15 is positioned above the second dispensing claw 22 and the two are in contact; and the third dispensing claw 16 is positioned above the third dispensing claw 23 and the two are in contact.

[0096] It also includes a PLC controller, which is electrically connected to the two main dispensing cylinders 8 and the two dispensing lowering cylinders 11.

[0097] The support gap and the peeling gap share the same gap. The material distribution claw 5 and the material distribution paddle 6, as well as the cylinders that drive them, are arranged in a one-to-one correspondence. The support components and the cylinders for driving the material distribution claw 5 and the material distribution paddle 6 are arranged around the through-hole 3, which makes the system layout as simple as possible and reduces the space occupied. The PLC controller controls these components to operate automatically in sequence, which greatly improves efficiency.

[0098] In one specific embodiment, the first material separating claw 14, the second material separating claw 15, the third material separating claw 16, the first material separating claw 20, the second material separating claw 22, and the third material separating claw 23 are all long rods, and the diameter of the long rod matches the size of the common gap 7, so that it can smoothly enter or leave the common gap 7.

[0099] In one specific embodiment, a support assembly is provided on both sides of the support platform 2 along the length direction, located opposite to the through opening 3. Each support assembly includes a material-supporting cylinder 24 fixed on the support platform 2. The piston of each material-supporting cylinder 24 is arranged horizontally and its free end is connected to a second vertical plate 25. Two horizontally arranged, spaced-apart material-supporting claws 26 are fixedly installed on opposite sides of the two second vertical plates 25. The PLC controller is electrically connected to the two material-supporting cylinders 24.

[0100] The lower ends of the two second vertical plates 25 extend downward from the support platform 2 and are located below the support platform 2. The two material-supporting flat claws 26 are installed on each second vertical plate 25 near its lower end, and the two material-supporting flat claws 26 are located below the support platform 2.

[0101] The two pallet claws 26 are located below the support platform 2, so that when supporting a stack of pallets 4, the position can be closer to the downstream conveyor belt 63. This allows the stripped individual pallets to fall with the shortest distance, avoiding the pallets from floating due to excessive distance and failing to fall accurately onto the downstream conveyor belt 63.

[0102] In one specific embodiment, each of the material-supporting flat claws 26 is presented as a U-shaped plate, and the bottom of the U-shaped plate is fixedly connected to the second vertical plate 25.

[0103] like Figure 2 As shown, it also includes four angle irons 27, which are installed one-to-one at the four corners of the through opening 3. The four angle irons 27 form four open spaces to accommodate the stack of trays 4. The open side between two angle irons 27 arranged at intervals along the length direction forms a space for the corresponding first material distribution claw 14, second material distribution claw 15, third material distribution claw 16, first material distribution lever 20, second material distribution lever 22 and third material distribution lever 23 to operate.

[0104] The support platform 2 is equipped with a support rod 28, which is positioned relative to the stack of pallets 4. A material shortage detection sensor 29 is installed on the support rod 28 at several pallets located at the lower position of the stack of pallets 4 to detect whether there are any pallets. A material loading detection sensor 30 is installed on the support rod 28 at several pallets located at the upper position of the stack of pallets 4 to detect whether there are any pallets. The PLC controller is electrically connected to the material shortage detection sensor 29 and the material loading detection sensor 30.

[0105] In one specific embodiment, the upstream transfer unit of the pallet includes:

[0106] The first conveyor line 31 extends parallel to the width direction. The first conveyor line 31 includes a first support frame 32, which includes a first upper mounting layer and a first lower mounting layer below the upper mounting layer. Two first conveyor belts 33, both arranged along the extension direction, and a first motor driving their rotation are disposed on the first upper mounting layer. The two first conveyor belts 33 are at the same height and have a first gap 34 between them. The bottom of the pallet to be dropped in the stack of pallets 4 has a middle section along its length direction, and two overlapping sections on either side of this middle section. The two overlapping sections are connected one-to-one to the two first conveyor belts. 33. A tray guard plate 35, arranged along the extending direction, is fixedly installed on the outer edge of each of the first conveyor belts 33 on the first support frame 32. The first lower mounting layer is a first horizontal base 36 fixedly connected to the first support frame. A first cylinder 37 is installed on the first horizontal base 36 at the position corresponding to the first gap 34. The piston of the first cylinder 37 extends vertically, and the free end of the piston is fixedly connected to a vertical moving platform 38. Slide rods, all arranged vertically and capable of moving up and down through the first horizontal base 36, are fixed at the four corners of the vertical moving platform 38. The width of the vertical moving platform 38 is... The width of the vertical moving platform 38 is not greater than the width of the first gap 34. A second cylinder 39 is mounted on the vertical moving platform 38 along the extending direction. The piston of the second cylinder 39 is also arranged along the extending direction, and a transfer tray plate 40 is fixed to the free end of the piston. The width of the transfer tray plate 40 is not greater than the width of the first gap 34 and matches the middle section of the tray to be dropped. Two sets of first tray sensors 41 are installed on the tray guard plate 35 near the first conveyor belt 33, arranged along the extending direction. These sensors are used to detect the last stack of trays 4 and the next second-to-last stack of trays 4 transported on the first conveyor belt 33, respectively. A first pressing plate is provided on the pallet guard plate 35 at the position corresponding to the last stack of pallets 4. A first pressing plate cylinder 42 is provided for each first pressing plate, which can drive the two first pressing plates to move towards each other or away from each other. A second pressing plate is provided on the two pallet guard plates 35 at the position corresponding to the next last stack of pallets 4. A second pressing plate cylinder 43 is provided for each second pressing plate, which can drive the two second pressing plates to move towards each other or away from each other. The PLC controller is electrically connected to the first motor, the first cylinder 37, the second cylinder 39, the two sets of first pallet sensors 41, the two first pressing plate cylinders 42, and the two second pressing plate cylinders 43.

[0107] The second conveyor line 44 extends parallel to the length direction. The second conveyor line 44 includes a second support frame 45, which includes a second upper mounting layer and a second lower mounting layer located below the upper mounting layer. The second upper mounting layer is provided with two second conveyor belts 46, both arranged along the length direction, for conveying the stack of pallets 4, and a second motor driving their rotation. The two second conveyor belts 46 are arranged at the same height and have a second gap 47 between them. The second conveyor belts 46 are located near the end of the first conveyor belt 33 and are lower than the height of the first conveyor belt 33. The second support frame 45 is located on the outer edge of each second conveyor belt 46. Each mounting rod 48 is fixedly installed vertically, corresponding to the first conveyor line 31. A second pallet sensor 49 is mounted on each mounting rod 48 to detect whether a stack of pallets 4 has been conveyed by the first conveyor line 31 to the top of the second conveyor belt 46. The second lower mounting layer is a second horizontal base 50 fixedly connected to the second support frame. A third cylinder 51 is installed on the second horizontal base 50 at a position corresponding to the second gap 47. The piston of the third cylinder 51 extends vertically, and its free end is fixedly connected to two parallel lifting plates 52 spaced apart along the length direction. These two lifting plates 52 correspond to the two first conveyor belts 33. The dimension between the two lifting plates 52 is not less than the dimension of the transfer tray plate 40, and each lifting plate 52 matches the overlapping section of the tray to be dropped. The piston stroke of the first cylinder 37 is set to enable it to move the vertical moving platform 38 upward into the first gap 34. The piston stroke of the second cylinder 39 is set to enable it to move the transfer tray plate 40 out of the end of the first conveyor belt 33 and extend above the second conveyor belt 46. The piston stroke of the third cylinder 51 is set to move upward to the height of the transfer tray plate 40 located above the second conveyor belt 46 and then lift the stack of trays 4 upward so that the stack of trays 4 leaves. The transfer tray plate 40 has an extension section extending from the end of the second lower mounting layer along its length direction to the end of the second conveyor belt 46. A fourth cylinder 53 is mounted on this extension section. The piston of the fourth cylinder 53 extends vertically, and a vertical baffle 54 is fixed to the free end of the piston. The vertical baffle 54 has two states: an upward extending state to block a stack of trays 4 located at the end of the second conveyor belt 46, and a downward retracted state not blocking a stack of trays 4. A vertical fixing plate is also mounted on the extension section, extending beyond the second conveyor belt from the side, and an end tray sensor is fixed thereon for detecting whether there is a stack of trays 4 at the end of the second conveyor belt 46.The PLC controller is electrically connected to the second motor, the third cylinder 51, the fourth cylinder 53, the second tray sensor 49, and the end tray sensor.

[0108] The pallet clamping part 55 includes a third support frame 56 located at the end of the second conveyor belt 46. The third support frame 56 is a cuboid frame with all six sides open, positioned above the support platform 2 of the pallet peeling part 1. Sprockets are mounted on one side of the cuboid frame at corresponding upper and lower positions along its width, and lifting chains 57 are mounted on these sprockets. The part also includes a drive motor 58 for rotating the sprockets, and a platform 59 disposed within the interior space of the cuboid frame and fixed to the chains. A slide rail extending along the length direction is provided on the lower surface of the platform 59. The slide rail 60 is provided inside the slide rail and moves back and forth along the slide rail. It also includes a slide rail drive cylinder, which is installed on one side of the platform 59 and whose piston moves back and forth along the length direction and is connected to the slide rail 60. A material clamping bidirectional cylinder 61 is fixedly installed on the lower surface of the slide rail 60. The two pistons of the material clamping bidirectional cylinder 61 are each fixed with a pallet clamp 62 arranged in a vertical direction. The pair of pallet clamps 62 are used to clamp a stack of pallets 4 located at the end of the second conveyor belt 46. The PLC controller is electrically connected to the drive motor 58, the slide rail drive cylinder and the material clamping bidirectional cylinder 61.

[0109] The transfer tray plate 40 of the first conveyor line 31, together with the two lifting plates 52 of the second conveyor line 44, can smoothly complete the transfer of a stack of trays 4 from the first conveyor line 31 to the second conveyor line 44. Moreover, this arrangement is completed within the vertical space of the first conveyor belt 33 and the second conveyor belt 46, without occupying too much external space.

[0110] like Figure 1 As shown, in one specific embodiment, there are three first conveyor lines 31, which are arranged in parallel at intervals. There are also three mounting rods 48 and three second tray sensors 49 located on them, each corresponding to one of the first conveyor lines 31.

[0111] The arrangement of three first conveyor lines 31 allows the first first conveyor line to complete the conveying of several groups of stacked pallets 4, and then the second first conveyor line to convey several groups of stacked pallets 4, and so on, until the third first conveyor line is used. This arrangement can greatly extend the automation time for conveying a stack of pallets 4 and reduce the time required to frequently place a stack of pallets 4 on the first conveyor line, allowing operators to free up extra time to do other work.

[0112] In one specific implementation, such asFigure 10 As shown, the downstream transfer section of the tray includes:

[0113] A downstream conveyor belt 63 and a third motor driving its rotation extend along the width direction, with its upstream section located below the support platform 2 at the position corresponding to the through opening 3. The downstream section of the downstream conveyor belt 63 is provided with pallet positioning block cylinders 64 disposed on both sides of the downstream conveyor belt 63 and facing each other. The piston of each pallet positioning block cylinder 64 extends along the length direction, and the free end of each piston is fixedly connected to a positioning block 65 for positioning a pallet being conveyed. A third pallet sensor 66 is provided on one side of the downstream conveyor belt 63 and upstream of the facing pallet positioning block cylinder 64. The filling unit is located above the pallet positioned by the positioning block 65. The PLC controller is electrically connected to the third motor, the pallet positioning block cylinder 64, and the third pallet sensor 66.

[0114] The positioning stop 65 enables precise positioning of the pallet on the downstream conveyor belt 63, thereby ensuring accurate subsequent filling.

[0115] Two tray positioning block cylinders 64, two positioning blocks 65 and a third tray sensor 66 form a positioning unit. There are two positioning units arranged sequentially along the conveying direction of the downstream conveyor belt 63. There are two sets of filling units. Each set of filling units includes a filling platform 64 mounted above the downstream conveyor belt 63 and corresponding to the position of the tray to be filled. The filling platform 64 is used to place the filling equipment.

[0116] During operation, the PLC controller controls the material-supporting cylinder 24's material-supporting claw 26 to lift a stack of pallets 4. The material-distributing claw 5 and material-distributing paddle 6 are arranged vertically adjacent to each other and are inserted into the shared gap 7 (e.g., Figure 4 At this time, the material-supporting flat claw 26 is retracted under the control of the material-supporting cylinder 24, and the material-distributing claw 6 is moved downward under the control of the material-distributing downward distributing cylinder 11 (e.g., Figure 5The bottommost pallet is pushed down onto the downstream conveyor belt 63. Then, the material distribution claw 6 returns to its original position, and the material support claw 26, controlled by the material support cylinder 24, returns to its lifting position. The material distribution claw 5 and the material distribution claw 6 retract, sharing the gap 7. The remaining stack of pallets 4 waiting to be unloaded falls freely onto the material support claw 26. At this point, one material distribution process is complete. Repeating the above process allows for continuous automatic pallet unloading. When the material shortage detection sensor 29 detects no pallets, it sends a predetermined signal. After receiving this signal, the PLC controller controls the pallet clamping part 55 to move (including controlling the drive motor 58 to move the platform 59 up and down, controlling the slide rail drive cylinder to move the slide rail 60 towards the pallet at the end of the second conveyor line 44, and controlling the material clamping bidirectional cylinder 61 to drive the pallet clamping plate 62 to open or return to clamp the stack of pallets 4), causing it to clamp the stack of pallets 4 from the end of the second conveyor line 44. After adding a stack of pallets 4, the loading detection sensor 30 detects the pallets and confirms the loading is complete.

[0117] The end-pallet sensor at the end of the second conveyor line 44 detects whether there is a stack of pallets 4 at that position. If there is, a signal is sent to the PLC controller to control the fourth cylinder 53 to drive the vertical baffle 54 to block the stack of pallets 4. If not, a signal is sent to the PLC controller to control the relevant components of the first conveyor line 31 and the second conveyor line 44 to realize the conveying of the stack of pallets 4. Specifically: the first extrusion plate cylinder 42 controls the first extrusion plate to return to its original position so that it does not extrude the last stack of pallets 4. At this time, the first cylinder 37 drives the vertical moving platform 38 to move upward to the first gap 34 to transfer the pallets 4. The pallet plate 40 lifts the last stack of pallets 4, and the second cylinder 39 drives the pallet plate 40 to move towards the second conveyor line 44, so that the stack of pallets 4 moves above the second conveyor belt 46. At this time, the third cylinder 51 drives the two lifting plates 52 to move upward, so as to lift the stack of pallets 4. Then the pallet plate 40 returns to its original position, and then the two lifting plates 52 move downward, so that the stack of pallets 4 is located on the two second conveyor belts 46. At this time, the second motor is controlled to make the second conveyor belt 46 rotate, so as to transport the stack of pallets 4 to the end of the second conveyor line 44.

[0118] The conveying process of several stacks of pallets 4 on the first conveyor line 31 is as follows: When the first pallet sensor 41 at the very end detects a pallet, it controls the first extrusion plate cylinder 42 to move the first extrusion plate towards the other side, so that it clamps the very last stack of pallets 4. When the first pallet sensor 41 at the next end detects a pallet, it controls the second extrusion plate cylinder 43 to move the second extrusion plate towards the other side, so that it clamps the very last stack of pallets 4. As mentioned above, when the end pallet sensor at the end of the second conveyor line 44 detects that there is no stack of pallets 4 at that position, it sends a signal to cause the first extrusion plate cylinder 42 to move... The first extrusion plate returns to its original position, and then the last stack of pallets 4 begins to be conveyed. When the first pallet sensor 41 at the very end detects that there is no pallet, it sends a signal to control the second extrusion plate cylinder 43 to drive the second extrusion plate back to its original position, so that the next stack of pallets 4 at the very end is conveyed to the end. At this time, when the first pallet sensor 41 at the very end detects that there is a pallet, it controls the first extrusion plate cylinder 42 again to move the two first extrusion plates toward each other and clamp the pallet. Similarly, when the first pallet sensor 41 at the very end detects that there is a pallet, it controls the second extrusion plate cylinder 43 again to move the two second extrusion plates toward each other and clamp the pallet.

[0119] The three first conveyor lines 31 are configured to first convey several stacks of pallets 4 on the first conveyor line, then on the second conveyor line, and finally on the third conveyor line.

[0120] This process is fully automated, greatly improving efficiency.

[0121] Furthermore, such as Figures 11-15 As shown, the insect-catching conveyor belt 68 extends parallel to the width direction of the tray and includes a fourth motor 69 for driving the insect-catching conveyor belt 68. The width of the insect-catching conveyor belt 68 matches the length of a single tray, and the PLC controller is electrically connected to the fourth motor 69. The insect-catching conveyor belt 68 and the fourth motor 69 driving it can be mounted on a support frame, such as... Figure 11 As shown.

[0127] An egg container 76 having a receiving space for holding a number of eggs, and a discharge port at the bottom of the container communicating with the receiving space;

[0128] A storage body 78 is located directly below and connected to the discharge port. The bottom of the storage body 78 has a discharge port. The storage body 78 is fixedly installed on a plate that can reciprocate under the control of an electromagnet switch 77. The plate has a discharge through hole corresponding to the discharge port. A feed pipe 79 and a delay pipe 80 are arranged below the plate and along the direction of the reciprocating movement of the plate. The reciprocating movement of the plate allows its discharge port to be connected only to the upper opening of the feed pipe 79 or only to the upper opening of the delay pipe 80.

[0129] A counter 81 is disposed between the feed port and the storage body 78 for counting the number of eggs falling from the feed port;

[0132] The buffer body includes a fifth motor and a horizontal disk 83 fixedly connected to the rotating shaft of the fifth motor. The rotating shaft is arranged in a vertical direction. The horizontal disk 83 has a thickness in the vertical direction. The horizontal disk 83 has four buffer holes 84 evenly spaced along its circumferential direction, penetrating the upper and lower sides of the horizontal disk 83. The motor drives the horizontal disk 83 to rotate so that the upper opening of each buffer hole 84 can be aligned with the lower opening of the feed tube 79 in sequence. A switch component that can open or close the lower opening of each buffer hole 84 is provided at the position of the lower opening of the buffer hole 84.

[0133] The end conveyor has a vertically oriented conveying channel with openings at both the top and bottom. The upper opening of the conveying channel corresponds sequentially to the lower opening of each of the buffer perforations 84 that rotate with the horizontal disc 83. The lower opening of the conveying channel forms the egg outlet. When the lower opening of one of the four buffer perforations 84 rotates to the upper opening of the corresponding conveying channel, the switch component corresponding to that buffer perforation 84 is in the open state, and the switch components corresponding to the other three buffer perforations 84 are in the closed state. The end conveyor and the feed pipe 79 are staggered by ninety degrees.

[0134] The installation positions of the first to eighth conveying units on the horizontal support platform 70 are as follows:

[0136] The insect-catching conveyor belt 68 is equipped with a first sensor for detecting the presence of a first tray 73, a second sensor for detecting the presence of a second tray 74, and a third sensor for detecting the presence of a third tray 75, sequentially installed along its sides in the upstream and downstream directions. Along its width, the conveyor belt 68 has opposing first baffles and cylinders 93 for extending or retracting the first baffles at positions corresponding to the first sensor and the first tray 73. Similarly, along its width, the conveyor belt 68 has opposing second baffles and cylinders 94 for extending or retracting the second baffles at positions corresponding to the second sensor and the second tray 74. Finally, along its width, the conveyor belt 68 has opposing third baffles and cylinders 95 for extending or retracting the third baffles at positions corresponding to the third sensor and the third tray 75.

[0137] The PLC controller is electrically connected to each of the counters 81, each of the electromagnet switches 77, each of the solenoid valves, each of the fifth motors, each of the switching components, sensor number one, sensor number two, sensor number three, two cylinder number one 93, two cylinder number two 94, and two cylinder number three 95.

[0138] In one specific embodiment, each of the switching components includes:

[0139] Mounting block 96 is fixedly mounted on the lower surface of horizontal disk 83 and arranged corresponding to buffer through hole 84. A notch is formed on mounting block 96 near the lower opening of buffer through hole 84.

[0140] A horizontal rotating shaft passes through the notch and extends one end out of the mounting block 96; the horizontal rotating shaft is rotatably mounted on the mounting block 96.

[0141] The sealing plate 97 is fixedly installed on a portion of the horizontal rotation axis located at the notch. It has a horizontal position and an inclined position. In the horizontal position, the sealing plate 97 closes the lower opening of the buffer through hole 84, and in the inclined position, the sealing plate 97 opens the lower opening of the buffer through hole 84.

[0142] A torsion spring, mounted on a horizontal rotation axis located at the notch and below the sealing plate 97, is used to provide a restoring force that keeps the sealing plate 97 in a horizontal position.

[0143] A wedge-shaped block 98 is fixedly installed at one end of the horizontal rotating shaft that extends out of the mounting block 96;

[0144] A buffer cylinder 99, the free end of the piston of which is directed toward the wedge block 98 to compress the wedge block 98 so that the sealing plate 97 is tilted by the horizontal rotating shaft;

[0145] The PLC controller is electrically connected to each of the buffer cylinders 99.

[0146] In one specific embodiment, the end conveyor is a funnel 100 with a large-diameter opening at the top and a small-diameter opening at the bottom. It also includes a horizontal support plate, which is fixed to the lower surface of the horizontal support platform by a third vertical plate. The funnel 100 passes through and is fixed to the horizontal support plate. It also includes a cone 101, which is vertically disposed at the small-diameter opening of the funnel 100 and its tip extends into the interior of the funnel 100. The cone 101 is fixed to the horizontal support plate by a fixing rod.

[0147] Furthermore, it also includes a horizontal support platform 102, which is fixedly installed above the horizontal bearing platform 70. Each of the fifth motors is installed on the horizontal support platform 102. The lower end of the rotating shaft of the fifth motor passes downward through the horizontal support platform 102 and the horizontal bearing platform 70 in sequence. The horizontal disc 83 is fixed to the rotating shaft located below the horizontal bearing platform 70. The electromagnet switch 77 is fixedly installed on the horizontal support platform 102. The lower end of the feed tube 79 is located below the horizontal bearing platform 70.

[0148] In one specific embodiment, the egg collection body 82 is an open cylindrical body that is fixedly installed on the horizontal support platform 70.

[0149] Each of the unit chambers 72 further includes a feed chamber 103, which is separated from the egg chamber 71. The feed chamber 103 is used to be filled with feed when passing through the filling section, and the egg chamber 71 is used to be filled with nutrient solution when passing through the filling section.

[0150] In one specific embodiment, the feed is hot feed, the nutrient solution is hot nutrient solution, and a cooling section is also included, which includes a cooling chamber and a cooling conveyor belt located in the cooling chamber. The upstream end of the cooling conveyor belt is connected to the downstream end of the downstream conveyor belt 63, and the downstream end of the cooling conveyor belt is connected to the upstream end of the insect-collecting conveyor belt 68.

[0151] In one specific embodiment, the two sets of filling units are a first filling unit and a second filling unit. The filling equipment of the first filling unit is equipped with the hot feed, and the filling equipment has eight first filling ports corresponding to the eight feed chambers 103. The filling equipment of the second filling unit is equipped with the hot nutrient solution, and the filling equipment has eight second filling ports corresponding to the eight egg chambers 71.

[0152] The filling process is as follows:

[0153] The first tray entering the downstream conveyor belt 63 is the first filling tray, followed by the second filling tray. When the first filling tray is detected by the upstream third tray sensor 66, a signal is sent to the PLC controller to activate the upstream tray positioning block cylinder 64, causing it to extend the positioning block 65 to block the first filling tray. At this time, a signal is sent to the PLC controller to stop the third motor, and the downstream conveyor belt 63 stops conveying. Then, the filling equipment in the first filling section fills the eight feed chambers 103 in the tray with hot feed. After filling is completed, the PLC controller activates the third motor, the downstream conveyor belt 63 begins conveying the tray, and the PLC controller activates the upstream tray positioning block cylinder 64, causing it to retract the positioning block 65 to retract and stop blocking the first filling tray. The first filling tray is then conveyed downstream. When a filling pallet is detected by the downstream third pallet sensor 66, a signal is sent to the PLC controller to activate the downstream pallet positioning block cylinder 64, causing it to extend the positioning block 65 to block the first filling pallet. At this time, the downstream conveyor belt 63 is still running until the second filling pallet is transported to the upstream third pallet sensor 66, where it is detected. Then, a signal is sent to the PLC controller to activate the upstream pallet positioning block cylinder 64, causing it to extend the positioning block 65 to block the second filling pallet. At this time, a signal is sent to the PLC controller to stop the third motor, and the downstream conveyor belt 63 stops transporting. Subsequently, the filling equipment of the first filling unit fills the eight feed chambers 103 in the second filling pallet with hot feed. At the same time, the filling equipment of the second filling unit fills the eight egg chambers 71 in the first filling pallet with hot nutrient solution; and so on.

[0154] The process of transferring eggs to trays 73 (number 1), 74 (number 2), and 75 (number 3) is as follows:

[0155] The PLC controller controls the fourth motor 69 to drive the insect-collecting conveyor belt 68 to rotate. Once the first tray 73 reaches a point where it is detected by the first sensor, a signal is sent to the PLC controller to activate the first cylinder 93, causing it to extend the first stop block to block the first tray 73. At this time, a signal is sent to the PLC controller to stop the fourth motor 69, and the insect-collecting conveyor belt 68 stops transporting insects. Subsequently, the PLC controller controls the buffer cylinder 99 of the first conveying unit 85 to activate, causing its piston to press against the wedge block 98, causing a fixed amount of eggs in the corresponding buffer perforation 84 to fall into the first egg chamber of the first tray 73. Simultaneously, the second conveying unit 86 causes a fixed amount of eggs in the corresponding buffer perforation 84 to fall into the third egg chamber of the first tray 73. The feeding process is relatively fast, completed at set intervals (e.g., 200-300 milliseconds). The buffer cylinders 99 are activated at any time, causing their pistons to retract so that the sealing plate 97 seals the corresponding buffer perforation 84. After the set interval... The PLC controller controls the fourth motor 69 to drive the insect-receiving conveyor belt 68 to continue rotating, and sends a signal to control the first cylinder 93 to retract the first stop block so as not to block the first tray 73. The first tray 73 continues to be conveyed until the second sensor detects the first tray 73, which is in the position of the second tray 74 (which can be referred to as the second tray 74). Then, a signal is sent to the second cylinder 94 to activate its piston to block the second tray 74. At this time, the insect-receiving conveyor belt 68 continues to rotate. When a new tray is conveyed to the position of the first tray 73, a signal is sent to stop the insect-receiving conveyor belt 68. At this time, the corresponding conveying units for the second tray 74 and the first tray 73 respectively activate to deliver a certain amount of eggs to the corresponding egg chamber 71. The feeding process is relatively fast, and the feeding is completed at set intervals (such as 200 milliseconds-300 milliseconds). The respective buffer cylinders 99 are controlled to activate at any time, so that their pistons retract and the sealing plate 97 seals the corresponding buffer perforation 84.After the set interval, the PLC controller controls the fourth motor 69 to drive the insect-catching conveyor belt 68 to continue rotating, and sends a signal to retract the pistons of cylinders 93 and 94. Trays 73 and 74 continue to be conveyed until sensor 3 detects tray 74, which is in the position of tray 75 (referred to as tray 75). Then, a signal is sent to cylinder 95, causing its piston to extend to block tray 75. Simultaneously, until sensor 2 detects tray 73, which is in the position of tray 74 (referred to as tray 74), a signal is sent to cylinder 94, causing its piston to extend to block tray 74. The insect-collecting conveyor belt 68 continues to rotate. Once a new tray is transported to the position of tray 73, a signal is given to stop the conveyor belt 68. Then, cylinder 93 actuates, extending its piston to block tray 73. The corresponding conveying units for trays 75, 74, and 73 activate, delivering a fixed quantity of eggs to the corresponding egg chambers 71. After a set interval (e.g., 200-300 milliseconds), the feeding is completed. At each interval, the buffer cylinder 99 is activated, retracting its piston to seal the corresponding buffer perforation 84. After this set interval, the PLC controller controls the fourth motor 69 to continue rotating the conveyor belt 68. This cycle repeats, synchronously transporting eggs to the three trays.

[0156] In the above actions, each conveying unit performs the following synchronized actions:

[0157] As mentioned above, a certain quantity of eggs in a buffer perforation 84 is transported to the egg chamber 71. Then, a signal is given to make the fifth motor rotate 90 degrees. At this time, the buffer perforation 84 is facing the feed pipe 79. At this time, the PLC controller controls the solenoid valve to open, and a number of eggs in the egg container 76 fall into the storage body 78. The storage body 78 transports the quantity of eggs to the corresponding buffer perforation 84 through the feed pipe 79 connected to it. The quantity of eggs is counted by the counter 81. After the counter 81 counts the quantity of eggs, a signal is given to make the solenoid valve close and control the electromagnet switch 77 to move, so that the storage body 78 corresponds to the delay tube 80. This causes a number of eggs that exceed the quantity of eggs due to the signal transmission delay to be transported to the egg collection body 82. These eggs can be reused. The process of the fifth motor rotating 90 degrees ensures that the buffer perforation 84, which already contains a fixed amount of eggs, is aligned with the funnel 100 below it, while the buffer perforation 84, which is now empty of eggs, is aligned with the feed pipe 79 above it. This configuration enables uninterrupted delivery of a fixed amount of eggs.
