Description

Technical Field

[0001] The present disclosure relates to lotus seed processing equipment, and in particular to a lotus seed shelling, peeling and core-clearing machine. Background Art

[0002] Traditional lotus seed processing requires manual labor to pick lotus pods from the fields, separate the lotus seeds from the pods, and then use a special blade to cut and shell the lotus seeds one by one. Because the lotus seeds are wrapped in a translucent outer skin, which tastes bitter and has no medicinal value, the shelled lotus seeds need to be immersed in water and the outer skin of the lotus seeds needs to be rubbed off by hand. This method of relying on manual labor is cumbersome, labor-intensive, time-consuming, labor-intensive, unhygienic, and very inefficient, and cannot meet market demand.

[0003] With the development of society and the advancement of science and technology, lotus seed processing equipment such as crushing, shelling, peeling, and core-cutting has emerged. Mechanization and automation are the inevitable development direction of lotus seed processing. However, existing lotus seed core-cutting equipment, lotus seed shelling equipment, and lotus seed peeling equipment are generally separate. The lotus seed core-cutting equipment is complex in structure, and lotus seeds are prone to deflection and misalignment during transportation. Generally, a color code detector is used to identify the head or tail end of the lotus seed to determine the lotus seed's direction, and then an air blowing mechanism is used to blow away the misaligned lotus seeds. Lotus seeds that are not completely shelled or peeled or are damaged are manually sorted out. This is inconvenient to operate, has low precision and efficiency, and is prone to missed picking, wrong picking, and plugging of the core-cutting needle. It also has poor stability and reliability, which affects the processing quality and yield of lotus seeds, is costly, and cannot meet the increasing production needs. Summary of the Invention

[0038] See also Figures 1 to 16 As shown, a lotus seed shelling, peeling and core-passing machine according to the present disclosure is schematically shown, comprising a machine body 1, on which are provided a first conveying device 2, a feeding device 3, a shelling device 4, a peeling device 5 and a core-passing machine 6. The feeding device 3, the shelling device 4 and the peeling device 5 are matched with the first conveying device 2 in sequence, the feeding device 3 is close to the feeding end of the first conveying device 2, and the peeling device 5 is located at the discharging end of the first conveying device 2. The core-passing machine 6 comprises a second conveying device 62, a detection component 63, a sorting component 64, a steering device 65 and a core-passing device 66. The detection component 63, the sorting component 64, the steering device 65 and the core-passing device 66 are matched with the second conveying device 62 in sequence, the detection component 63 is close to the feeding end of the second conveying device 62, the core-passing device 66 is close to the discharging end of the second conveying device 62, and the discharging port of the peeling device 5 is matched with the feeding end of the second conveying device 62 through the first discharging chute 53.

[0039] During use, the lotus seeds to be processed are sequentially conveyed into the first conveying device 2 through the feeding device 3. The shelling device 4 first shells the lotus seeds conveyed on the first conveying device 2 one by one, and then the peeling device 5 peels the peeled lotus seeds one by one. The peeled lotus seeds pass through the first discharging chute 53 and enter the second conveying device 62 of the core-passing machine 6 one by one for conveying. The detection component 63 first detects and identifies the lotus seeds conveyed on the second conveying device 62 in turn, quickly and accurately determines the direction of the lotus seeds, and determines whether the lotus seeds are not completely shelled, not completely peeled or damaged, and then determines the lotus seeds according to the detection component 63. Based on the detection results, the sorting component 64 knocks out the defective lotus seeds on the second conveyor 62. The knocked out defective lotus seeds can be collected by corresponding devices for subsequent processing. Then, the steering device 65 redirects the lotus seeds on the second conveyor 62 that are in the wrong direction, for example, rotating the reversed lotus seeds 180° and placing them back on the second conveyor 62. Then, the core-clearing device 66 cores the lotus seeds on the second conveyor 62 in turn. Finally, the second conveyor 62 conveys the cored lotus seeds to corresponding boxes for collection, thereby realizing the integrated automatic processing of shelling, peeling, and core-clearing of lotus seeds.

[0040] The first conveyor device 2, feeding device 3, shelling device 4, and peeling device 5 are all components of existing lotus seed shelling and peeling equipment and will not be described in detail here. Typically, the first conveyor device 2 includes a first conveyor belt 21 for conveying the lotus seeds. The first conveyor belt 21 is driven by a first drive mechanism 22. The first drive mechanism 22 can utilize a motor, such as a drive shaft or a drive wheel, to drive the first conveyor belt 21 for conveyance. The first conveyor device 2 also includes a booster support assembly 23 that cooperates with the first conveyor belt 21, and an alignment assembly 24 for aligning the lotus seeds. The feeding device 3 typically includes a feed hopper and a turntable driven by a drive mechanism such as a motor. The turntable is circumferentially provided with positioning slots for positioning the lotus seeds. Each positioning slot can accommodate only one lotus seed. Lotus seeds to be processed in the feed hopper are fed one by one into the positioning slots on the turntable via a vibrating baffle mechanism. The turntable then rotates, feeding the lotus seeds one by one onto the first conveyor device 2 for transport. The shelling device 4 includes a first mounting base 44, which is equipped with a first cover plate 41 positioned above the first conveyor belt 21, a first cutter 42 positioned above the first cover plate 41, a second drive mechanism 43 for driving the first cutter 42, and a first flushing pipe 45 corresponding to the first cutter 43. The first cover plate 41 is provided with a first avoidance hole 411 corresponding to the first cutter 42. The second drive mechanism 43 normally drives the first cutter 42 to reciprocate along the lotus seed conveying direction to shell the lotus seeds on the first conveyor belt 21. The peeling device 5 includes a clamping assembly 51 located at the discharge end of the first conveyor device 2 and a water gun assembly 52 for peeling the lotus seeds. The water gun assembly 52 is capable of peeling the lotus seeds clamped by the clamping assembly 51. A first pump body 7 supplies water to the water gun assembly 52. After peeling, the lotus seeds fall into the first discharge chute 53 and then enter the core-clearing machine 6 for core-clearing.

[0041] A feeding device 68 is also provided on the frame 61 of the core-clearing machine 6. The structure of the feeding device 68 is basically the same as that of the loading device 3. The discharge port of the peeling device 5 corresponds to the feed hopper of the feeding device 68 through the first discharge trough 53. The feeding device 68 has the functions of buffering, transition, and storage, which can ensure that the lotus seeds enter the second conveying device 62 for conveying more stably in sequence.

[0042] The second conveying device 62, the detection component 63, the sorting component 64, the steering device 65 and the core-passing device 66 are arranged on the frame 61. The frame 61 is installed at one end of the body 1, for example, by fasteners such as screws, so that the core-passing machine 6 is installed as a whole at one end of the body 1, which is more convenient to operate.

[0043] The first conveyor 2, feeding device 3, shelling device 4, and peeling device 5 can be two sets and respectively arranged on either side of the machine body 1. The feeding device 68, second conveyor 62, vibration and pressure straightening assembly 67, detection assembly 63, sorting assembly 64, steering device 65, and core-passing device 66 can also be two sets and respectively arranged on either side of the frame 61. That is, the lotus seed shelling, peeling, and core-passing machine has a dual-station structure. The first conveyor 2, shelling device 4, peeling device 5, second conveyor 62, steering device 65, and core-passing device 66 can also share a single drive mechanism, which drives each device through its corresponding drive mechanism, resulting in a more compact and stable structure, smaller size, and greater stability and reliability. The frame 61 and the machine body 1 are also provided with a waterproof cover, and the corresponding devices are located in the waterproof cover, which is safer and more reliable.

[0044] The second conveyor device 62 includes a conveyor chain 621, a first driving wheel 622, and a first driven wheel 623 that cooperate with the conveyor chain 621. The first driving wheel 622 is driven by a third drive mechanism 624. The first driving wheel 622 and the first driven wheel 623 cooperate to drive the conveyor chain 621. The conveyor chain 621 is formed by a plurality of first rollers 625 connected in sequence. The first rollers 625 are rotatable, and between two adjacent first rollers 625, first positioning areas 626 are formed for positioning lotus seeds. Each first positioning area 626 can accommodate only one lotus seed. The third drive mechanism 624 drives the first driving wheel 622 to rotate. The first driving wheel 622 and the first driven wheel 623 cooperate to drive the conveyor chain 621. Lotus seeds to be processed fall into the first positioning areas 626 one by one, thereby sequentially positioning and conveying the lotus seeds to be processed. The third drive mechanism 624 can use an electric motor or motor to directly drive the first driving wheel 622, or it can use an electric motor or motor to drive the first driving wheel 622 through a transmission mechanism such as a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. The third drive mechanism 624 can also use other suitable power mechanisms known in the art. The first roller 625 can be made entirely of a flexible material, or a roller with a flexible layer or a rubber-coated wheel, such as a silicone wheel, can be used to better compress the lotus seeds and reduce damage to the lotus seeds. The surface of the first roller 625 is provided with grooves along its circumference, typically located in the middle of the first roller 625, making the structure more compact and stable, and capable of more stable and reliable compression of the lotus seeds.

[0045] A vibration and pressure straightening component 67 is provided between the steering device 65 and the core-passing device 66 and / or at the end of the detection component 63 away from the sorting component 64. Usually, a vibration and pressure straightening component 67 is provided between the steering device 65 and the core-passing device 66 and at the end of the detection component 63 away from the sorting component 64, that is, the transported lotus seeds are first vibrated and straightened, and then the detection component 63 detects the lotus seeds. After the steering device 65 steering the lotus seeds, the transported lotus seeds are vibrated and straightened again, and then the core-passing device 66 performs core processing on the lotus seeds.

[0046] The vibration-pressure straightening assembly 67 includes a first support plate 671 and an elastic pressure block 672. The elastic pressure block 672 is mounted on a corresponding bracket. Both the bracket and the first support plate 671 are mounted on the frame 61. The first support plate 671 is located below the conveyor chain 621 to support the conveyor chain 621. The elastic pressure block 672 is fixedly mounted above the first support plate 671 and moves above the conveyor chain 621. Two first limiting bars 673 and a bracket for mounting the two first limiting bars 673 are also symmetrically disposed on the first support plate 671. The elastic pressure block 672 is generally located above and between the two first limiting bars 673. The length of the elastic pressure block 672 is aligned with the length of the two first limiting bars 673. The conveyor chain 621 is conveyed along the first support plate 671 and passes between the two first limiting strips 673 and under the elastic pressure block 672. The lotus seeds are positioned in sequence in the first positioning interval 626 on the conveyor chain 621. The two first limiting strips 673 can prevent the roller chain from deflecting. The friction between the elastic pressure block 672 and the conveyor chain 621 can drive the first roller 625 to rotate. The interaction between the elastic pressure block 672 and the conveyor chain 621 can make the elastic pressure block 672 vibrate to elastically vibrate and press the lotus seeds, so that the lotus seeds in the first positioning interval 626 and the lotus seeds standing in the first positioning interval 626 can be leveled, thereby leveling and straightening the lotus seeds that are skewed, misaligned, or standing in the first positioning interval 626, which is convenient for subsequent direction identification and core processing of the lotus seeds.

[0047] The elastic pressure block 672 can be made of an elastic material such as rubber, urethane foam, or silicone, for example, a silicone pressure block. The feed end of the elastic pressure block 672 is provided with a guide surface for engaging the lotus seeds. The first guide surface can be an inclined surface or other appropriately shaped surface. The guide surface guides the lotus seeds on the conveyor chain 621, facilitating their entry beneath the elastic pressure block 672 and allowing for the placement of upright lotus seeds, thereby providing greater stability and reliability.

[0048] Grooves for cooperating with the conveyor chain 21 are respectively provided on the opposite sides of the two first limit bars 673. The conveyor chain 621 passes between the two first limit bars 673 along the first support plate 671. At the same time, the two sides of the conveyor chain 621 pass along the grooves on the two first support plates 671, thereby preventing the roller chain from deviating, shaking up and down, etc., and the structure is more compact, stable, and reliable.

[0049] Regarding the vibration and pressure straightening assembly 67, which is positioned between the steering device 65 and the core-passing device 66, a first pressure roller 675 is positioned above the first support plate 671 to mate with the core-passing device 66. The conveyor chain 621 passes along the first support plate 671 between the two first limiting bars 673, and then sequentially passes under the elastic pressure block 672 and the first pressure roller 675. The first pressure roller 675 is capable of compressing the lotus seeds in the first positioning section 626 below. The two first rollers 625 that position the lotus seeds and the first pressure roller 675 form a three-roller centering structure, which can also be a three-roller centering structure or a three-axis centering structure. The core-passing device 66 then cores the lotus seeds. The first pressure roller 675 is mounted on a fourth bracket 674, which is equipped with a pin or a rotating shaft that connects to the first pressure roller 75. The first pressure roller 675 can also rotate freely. The first pressure roller 675 is essentially the same as the first roller 625, and the structure of the first roller 625 is referred to above. The two first limit bars 673 are respectively provided with avoidance grooves for cooperating with the core-passing device 66. The two avoidance grooves correspond to each other. The first support plate 671 can also be provided with a core receiving bucket for cooperating with the core-passing device 66. The lotus core passed out is collected and processed by the corresponding collecting device along the core receiving bucket.

[0050] The first support plate 671 is provided with a friction plate 676 for cooperating with the conveyor chain 621. The friction plate 676 is located between the two first limit bars 673. The conveyor chain 621 passes between the two first limit bars 673 and above the friction plate 676. The friction plate 676 can increase the friction between the first roller 625 and the first roller 625, facilitating better rotation of the first roller 625 and better elastic vibration and pressure of the elastic pressure block 672 on the lotus seeds, thereby better aligning the lotus seeds. The friction plate 676 can be made of the same material as the elastic pressure block 672, such as a silicone plate, or other suitable material plates. The friction plate 676 is provided with a friction structure for cooperating with the first roller 625. The friction structure can be a uniformly distributed groove body, protrusions, a toothed structure, or other suitable friction texture, or it can be a set friction layer, friction surface, friction film, etc.

[0051] The detection component 63 includes a first bracket 631, and at least one first camera 632 for detecting lotus seeds is provided on the first bracket 631. The first camera 632 can be one, two or more, and the number and arrangement of the first cameras 632 are determined according to the specific situation. Figure 8 As shown, two first cameras 632 are symmetrically arranged on the first bracket 631. These cameras can detect and identify the lotus seeds in the middle from both sides. Lotus seeds are sequentially placed on the conveyor chain 621 of the second conveyor device 62 for transport. The two first cameras 632, located on either side of the conveyor chain 621, can comprehensively detect and identify the lotus seeds from both the head and tail, providing higher accuracy, stability, and reliability. Furthermore, more first cameras 632 can be used to detect and identify the lotus seeds from different directions.

[0052] The first camera 632 is a camera, such as a high-speed camera, CCD camera, or CMOS camera, which allows for more accurate and comprehensive photo detection of lotus seeds. The first bracket 631 is provided with two first reflectors 633 that cooperate with the first camera 632 and a first fixing plate 634 on which the two first reflectors 633 are mounted. The two first reflectors 633 are symmetrically located on either side of the first camera 632. The first reflectors 633 can be reflective mirrors, plane mirrors, spherical mirrors, or aspherical mirrors. Through reflection, the two first reflectors 633 enable the first camera 632 to more accurately and comprehensively detect lotus seeds. This eliminates the need for multiple cameras to take photos from different directions, resulting in a simpler structure and easier operation. The two first reflectors 633 are typically symmetrically located on either side in front of the first camera 632, resulting in higher detection accuracy and better results. The first bracket 631 may also be provided with reinforcing ribs and a light source that cooperates with the first camera 632.

[0053] The sorting assembly 64 includes a first removal rod 641 and a fourth drive mechanism 642. The fourth drive mechanism 642 is mounted on a third bracket 643, which is mounted on the frame 61 via screws or other fasteners. The fourth drive mechanism 642 drives the first removal rod 641 to move, which can be reciprocating linear motion or rotational motion. The first removal rod 641 and the fourth drive mechanism 642 can be one group, two groups, or multiple groups. Based on the detection results of the detection assembly 63, the fourth drive mechanism 642 drives the first removal rod 641 to move, which can remove defective lotus seeds in the corresponding position. The removed lotus seeds can be collected by a corresponding device, thereby achieving sorting of the lotus seeds, facilitating better core processing of the lotus seeds later. The frame 61 is also provided with a sorting hopper corresponding to the sorting assembly 64. The removed lotus seeds enter the corresponding collection device through the sorting hopper.

[0054] The head of the first removing rod 641 is provided with a first impact block for cooperating with the lotus seeds. The first impact block can be made of flexible material or have a flexible layer, such as a rubber sleeve, a silicone sleeve, etc., to reduce damage to the lotus seeds, etc. The diameter of the first impact block can be larger than the diameter of the first removing rod 641 to increase the contact area, etc.

[0055] The fourth driving mechanism 642 can be a motor, a motor, a reduction motor, an air cylinder, an oil cylinder, an electric cylinder, a linear module, an electromagnet, etc. Figure 7 、 Figure 16 As shown, the fourth driving mechanism 642 adopts a motor, and the first removing rod 641 is located above the conveyor chain 621. One end of the first removing rod 641 is fixedly connected to the output shaft of the motor. The motor drives the first removing rod 641 to rotate to knock off the defective lotus seeds on the conveyor chain 621. The motor is installed on the corresponding bracket. The bracket can also be provided with a detection switch that cooperates with the first removing rod 641, such as a photoelectric switch, etc. The structure is simple and stable, the operation is convenient, and it is more stable and reliable. There are more than two fourth drive mechanisms 642. The more than two fourth drive mechanisms 642 can be arranged side by side or arranged up and down. The fourth drive mechanisms 642 correspond to the first removing rod 641 one by one. Lotus seeds with different defects correspond to different fourth drive mechanisms 642 and first removing rods 641. For example, lotus seeds that are not completely shelled, lotus seeds that are not completely peeled, and broken lotus seeds each correspond to a set of fourth drive mechanisms 642 and first removing rods 641 separately. Lotus seeds with similar defects that can be processed together can also share a set of fourth drive mechanisms 642 and first removing rods 641. More than two fourth drive mechanisms 642 can separately drive the first removing rod 641 that cooperates with them to rotate, so that lotus seeds with different defects can be sorted separately, which is more convenient for subsequent processing of defective lotus seeds.

[0056] like Figure 9 As shown, the fourth drive mechanism 642 is an electromagnet. The first removal rod 641 is located on one side of the lotus seeds on the conveyor chain 621. The electromagnet pushes the first removal rod 641 in a reciprocating linear motion to remove defective lotus seeds. The electromagnet can be a push-pull electromagnet or an electromagnetic push rod. The electromagnet has a compact, stable structure and a small size. The strength and presence of magnetism can be adjusted, the direction of the magnetic pole can be changed, etc., making it very easy to control and adjust. As mentioned above, the electromagnet corresponds to the first removal rod 641 one-to-one. The electromagnet and the first removal rod 641 can be two or more groups, so that lotus seeds with different defects can be sorted separately, which further facilitates the subsequent processing of defective lotus seeds.

[0057] The steering device 65 includes a pick-up assembly 651, a sixth drive mechanism 652, and a seventh drive mechanism 653. The sixth drive mechanism 652 and the seventh drive mechanism 653 are mounted on the frame 61. The pick-up assembly 651 is connected to the seventh drive mechanism 653, and the sixth drive mechanism 652 is connected to the seventh drive mechanism 653. During use, if lotus seeds on the second conveyor 62 are facing the wrong direction, the sixth drive mechanism 652 drives the pick-up assembly 651 and the seventh drive mechanism 653 to move up and down together, causing the pick-up assembly 651 to pick up the lotus seeds on the second conveyor 62. The seventh drive mechanism 653 then drives the pick-up assembly 651 to rotate, causing the lotus seeds picked up by the pick-up assembly 651 to be redirected, for example, by rotating the reversed lotus seeds 180 degrees. The redirected lotus seeds are then placed back on the second conveyor 62, thereby achieving the desired direction of the lotus seeds. This provides convenient operation, a simplified structure, high precision, high efficiency, and facilitates subsequent core processing of the lotus seeds.

[0058] The material picking assembly 651 includes a first connecting rod 6511, the upper end of the first connecting rod 6511 is connected to the seventh driving mechanism 653, the lower end of the first connecting rod 6511 is provided with a material picking part 6512 for picking up materials and a first fixing sleeve 6513 for fixing the material picking part 6512, the seventh driving mechanism 6653 is arranged on the second bracket 654, the second bracket 654 is installed on the frame 61, the second bracket 654 is provided with a stripping plate 6543 that cooperates with the first fixing sleeve 6513, the stripping plate 6543 is provided with a first through hole 65431 that cooperates with the first fixing sleeve 6513, the diameter of the first through hole 65431 is smaller than the diameter of the lotus seed, and the diameters of the first connecting rod 6511 and the first fixing sleeve 6513 are also smaller than the diameter of the first through hole 65431. The material picking part 6512 can adopt a needle, a clamp, tweezers, a vacuum suction cup or other suitable structures in the prior art. The needle can be a metal needle. The needle can be one, two or more. Under the premise of ensuring that the needle can be inserted into the lotus seeds and lift the lotus seeds, the needle should be as thin as possible to reduce damage to the lotus seeds. During use, the sixth driving mechanism 652 drives the material picking assembly 651 and the seventh driving mechanism 653 to move up and down together, so that the material picking part 6512 picks up the lotus seeds from the first positioning interval 626. After the seventh driving mechanism 653 drives the material picking assembly 651 to rotate to complete the turning of the lotus seeds, the sixth driving mechanism 652 continues to drive the material picking assembly 651 and the seventh driving mechanism 653 to move upward together. As the first fixing sleeve 6513 passes upward through the first through hole 65431, since the size of the lotus seeds is larger than the first through hole 65431, the stripping plate 6543 can block the lotus seeds, causing the lotus seeds to fall off the material picking part 6512 and fall back into the first positioning interval 626, thereby realizing the discharge of the lotus seeds after the turning. The structure is simple, stable and reliable.

[0059] The stripping plate 6543 can be made of metal plate, plastic plate or other suitable materials. A flexible pressing plate 6544 is arranged below the stripping plate 6543, such as silicone skin, rubber skin, etc. The pressing plate 6544 is tilted and can swing up and down. The upper end of the pressing plate 6544 is close to the feed end and is connected to the stripping plate 6543, for example, it is fixed or hinged with fasteners such as screws. The lower end of the pressing plate 6544 is close to the discharge end and is suspended in the air. A second through hole 65441 is provided on the pressing plate 6544 to match the first fixed sleeve 6513. The diameter of the second through hole 65441 is smaller than the diameter of the lotus seed. The second through hole 65441 is coaxial with the first through hole 65431 and is basically the same size. The feed end and the discharge end are relative to the conveying direction of the lotus seed. During use, the inclined pressing plate 6544 can block and limit the corresponding lotus seeds, prevent the lotus seeds from jumping, and ensure that the material taking part 6512 can pick up the lotus seeds more stably. As the material taking component 651 and the lotus seeds move upward, the lotus seeds can drive the flexible pressing plate 6544 to swing upward synchronously until the flexible pressing plate 6544 is attached to the bottom surface of the stripping plate 6543, and then the lotus seeds are stripped by the restriction of the stripping plate 6543. The flexible pressing plate 6544 can also provide buffer protection for the lotus seeds, reduce damage to the lotus seeds, ensure better stripping of the lotus seeds, and prevent the lotus seeds from jumping. In addition, the pressing plate 6544 can also be made of a metal plate, a plastic plate, or an elastic plate. The upper end of the pressing plate 6544 is close to the feed end and is hinged to the stripping plate 6543, and the lower end of the pressing plate 6544 is close to the discharge end and is suspended.

[0060] The bottom surface of the first connecting rod 6511 is provided with a slideway along the vertical direction, which cooperates with the upper end of the first fixed sleeve 6513. The first connecting rod 6511 is provided with a limiting long groove in the vertical direction and connected to the slideway. A first spring 6514 is provided in the slideway. The upper end of the first spring 6514 presses against the top of the slideway, and the lower end of the first spring 6514 presses against the top of the first fixed sleeve 6513. The first fixed sleeve 6513 is provided with a hole body that can correspond to the limiting long groove. A limiting member such as a screw or a pin passes through the limiting long groove and the hole body, that is, one end of the limiting member is connected to the first fixed sleeve 6513 and the other end thereof is located in the limiting long groove. When the feeding portion 6512 moves downward to retrieve lotus seeds, the lotus seeds exert a certain reverse force on the feeding portion 6512, causing the first fixing sleeve 6513 to slide upward along the slideway and the limiting member to simultaneously slide upward along the limiting slot. The first spring 6514 is compressed, thereby providing buffering protection for the feeding. The first spring 6514 can also push the first fixing sleeve 6513 and the feeding portion 6512 to automatically reset. The limiting slots can be symmetrically provided on both sides of the first connecting rod 6511, and the hole body can be a threaded hole or a through hole, etc., which has a simple structure and is more convenient to operate. The first fixing sleeve 6513 includes a connecting rod and a chuck. The hole body is provided at the upper end of the connecting rod, and the chuck is connected to the bottom of the connecting rod, such as by a threaded connection. The chuck cooperates with the connecting rod to fix the feeding portion.

[0061] The seventh drive mechanism 653 is a motor with its output end facing downward and connected to the picking assembly 651. The motor is mounted on the first support 6532. The sixth drive mechanism 652 is connected to the first support 6532. Typically, the motor's output shaft is coaxially connected to the first connecting rod 6511 of the picking assembly 651. The sixth drive mechanism 652 drives the first support 6532 to move up and down, causing the seventh drive mechanism 653 and the picking assembly 651 to move up and down as a whole. The motor drives the picking assembly 651 to rotate, causing the lotus seeds picked up by the picking assembly 651 to be diverted. The seventh drive mechanism 653 can also be a rotary cylinder, a rotating table, or other suitable power mechanism known in the art.

[0062] A first guide mechanism 6541 is vertically mounted on the second bracket 654, cooperating with the first support 6532. The sixth drive mechanism 652 drives the first support 6532 up and down, while the first support 6532 simultaneously moves up and down along the first guide mechanism 6541, providing more stable and reliable movement. The first guide mechanism 6541 may be a linear slide, or a structure of a slider and a slide groove.

[0063] The sixth drive mechanism 652 can use a pneumatic cylinder, an oil cylinder, an electric cylinder, a linear module, or the like to drive the seventh drive mechanism 653 to move up and down. The sixth drive mechanism 652 can also drive the seventh drive mechanism 653 to move up and down via a pull rod assembly 655 or the like. The pull rod assembly 655 includes a first rotating shaft 6551, a first swing arm 6552, and a first pull rod 6553. One end of the first swing arm 6552 is fixedly connected to the first rotating shaft 6551, and the other end thereof cooperates with the sixth drive mechanism 652. One end of the first pull rod 6553 is fixedly connected to the first rotating shaft 6551, and the other end thereof is connected to the first support 6532 of the seventh drive mechanism 653 via a first chain 6555. That is, one end of the first chain 6555 is connected to the first pull rod 6553, and the other end thereof is connected to the first support 6532 of the seventh drive mechanism 653, for example, by a hinged connection such as a pin. The sixth drive mechanism 652 drives the first swing arm 6552 to swing, which in turn drives the first rotating shaft 6551 to rotate synchronously. The first rotating shaft 6551 then drives the first pull rod 6553 to swing synchronously, causing the first chain 6555 to pull the first support 6532 of the seventh drive mechanism 653 up and down along the first guide mechanism 6541. The first chain 6555 is a flexible connection, providing greater flexibility, stability, and reliability. Alternatively, the first chain 6555 can be replaced by a connecting rod, one end of which is hinged to the first pull rod 6553 and the other end of which is hinged to the first support 6532 of the seventh drive mechanism 653.

[0064] The sixth drive mechanism 652 drives the first swing arm 6552 to swing via the first cam 6521. The first swing arm 6552 is provided with a first pulley 6554 that cooperates with the first cam 6521. The seventh drive mechanism 653's own gravity maintains the first pulley 6554 in constant contact with the first cam 6521. The sixth drive mechanism 652 drives the first cam 6521 to rotate, which in turn drives the first swing arm 6552 to swing via the first pulley 6554. The first cam 6521 is typically mounted on a rotating shaft, which can be driven directly by an electric motor, or through a belt drive, chain drive, or gear drive. The sixth drive mechanism 652 can also utilize a pneumatic cylinder, oil cylinder, electric cylinder, or the like to directly drive the first swing arm 6552 to swing.

[0065] The second bracket 654 is provided with a first electromagnet 6545 and a first connecting plate 6542 for mounting the first electromagnet 6545. The first support 6532 is provided with a second connecting plate 6533 corresponding to the first electromagnet 6545. The second connecting plate 6533 is a magnetic plate. The first electromagnet 6545 is located above the second connecting plate 6533. During use, for lotus seeds with the correct direction and no need to turn, when the seventh drive mechanism 653 and the material picking assembly 651 are in a high position, the first electromagnet 6545 is energized, and the first electromagnet 6545 magnetically attracts the second connecting plate 6533, so that the seventh drive mechanism 653 and the material picking assembly 651 are fixed in a high position as a whole. Since the first chain 6555 is a soft connection and can bend freely, the sixth drive mechanism 652 drives the pull rod assembly 655 to move through the first cam 6521. At this time, only the first chain 6555 bends, etc., and cannot drive the seventh drive mechanism 653 and the material picking assembly 651 to move downward together, that is, the material picking assembly 651 cannot move downward to pick up materials, thereby preventing the material picking assembly 651 from picking up lotus seeds that do not need to be turned, reducing damage to the lotus seeds, etc.

[0066] The first connecting plate 6542 and the second connecting plate 6533 are connected by a second spring 6531. The second spring 6531 is arranged in the vertical direction. The first connecting plate 6542 is located above the second connecting plate 6533. The upper end of the second spring 6531 is connected to the first connecting plate 6542 and the lower end is connected to the second connecting plate 6533, such as by welding or by providing screws on the first connecting plate 6542 and the second connecting plate 6533 respectively and inserting them into the two ends of the second spring 6531. The number and arrangement of the second springs 6531 depend on the specific situation. Usually, there are more than two second springs 6531 symmetrically or evenly distributed. The second springs 6531 have the functions of buffering protection and elastically supporting the seventh driving mechanism 653, so that the structure is more stable and reliable.

[0067] The core-passing device 66 comprises a core-passing assembly 661, a punch assembly 662, and a fifth drive mechanism 663. The core-passing assembly 661 has a hollow, thin, needle-shaped core-passing nozzle 6611, also known as a core-passing needle. The punch assembly 662 is connected to the core-passing nozzle 6611 via a pipeline and is typically connected to a supply device such as a water pump, air pump, or spray pump. The punch assembly 662 can be controlled by a separate hydraulic or air system. Alternatively, the punch assembly 662 can be driven by the fifth drive mechanism 663. In other words, the core-passing assembly 661 and the punch assembly 662 can share the fifth drive mechanism 663, resulting in a simpler, more compact, and energy-efficient structure.

[0068] During use, the two first rollers 625 for positioning the lotus seeds and the first pressing wheel 675 form a three-axis centering structure, thereby pressing and fixing the lotus seeds to be cored. The core punch assembly 662 is connected to the core-passing nozzle 6611 through a pipeline. The fifth driving mechanism 663 can drive the core-passing assembly 661 to move, so that the core-passing nozzle 6611 with a hollow structure can core the lotus seeds positioned and fixed on the second conveying device 62. The lotus seeds that are passed out are usually at least partially located in the core-passing nozzle 6611, and as the core-passing nozzle 6611 moves, the lotus seeds are passed out. To remove the lotus core, the fifth driving mechanism 663 can simultaneously drive and control the core punch assembly 662 to supply air or liquid, such as water, compressed air, etc., to the hollow core nozzle 6611, and flush the lotus core out of the core nozzle 6611 through a pressurized or high-pressure air flow or liquid flow, thereby completing the core processing of the lotus seeds and simultaneously clearing the lotus core in the core nozzle 6611, facilitating efficient and automated core processing of lotus seeds, and preventing the core nozzle 6611 from being clogged. It has high stability and reliability, thereby improving the processing quality and yield of lotus seeds.

[0069] The core-passing assembly 661 includes a first push rod 6612 and a core-passing nozzle 6611. The core-passing nozzle 6611 is arranged at one end of the first push rod 6612. The fifth driving mechanism 663 cooperates with the end of the first push rod 6612 away from the core-passing nozzle 6611. The first push rod 6612 is provided with a first connector 6616 connected to the core-passing nozzle 6611, such as a quick water pipe connector, a quick air pipe connector, a pagoda connector, etc. The first connector 6616 is connected to the core-passing assembly 662 through a pipeline. One end of the core-passing nozzle 6611 is usually provided with a connector threadedly connected to the first push rod 6612. A channel connected to the core-passing nozzle 6611 and the first connector 6616 is provided in the first push rod 6612. During use, the fifth driving mechanism 663 drives the first push rod 6612 to move back and forth in a straight line, so that the core-passing nozzle 6611 performs core-passing processing on the lotus seeds positioned on the second conveying device 62, and as the core-passing nozzle 6611 passes the lotus core out, the fifth driving mechanism 663 simultaneously drives the control core punch assembly 662 to supply air or liquid to the hollow structure of the core-passing nozzle 6611 through the first joint 6616, and the lotus core is flushed out of the core-passing nozzle 6611 by means of pressurized or high-pressure air or liquid flow.

[0070] The punch assembly 662 includes a second support 6621, which is provided with a channel, a second push rod 6624, a second connector 6622, and a first valve 6623. The second connector 6622 and the first valve 6623 are respectively connected to the channel. The second connector 6622 is connected to a corresponding supply device such as a water pump, an air pump, or a spray pump via a pipeline. The first valve 6623 is connected to the core nozzle 6611 via a pipeline. During use, as the core-passing nozzle 6611 passes the lotus core out, the fifth driving mechanism 663 simultaneously drives the second push rod 6624 to move linearly, so that the first valve 6623 opens to supply air or liquid to the hollow structure of the core-passing nozzle 6611, and the lotus core is flushed out of the core-passing nozzle 6611 by the pressurized or high-pressure air flow or liquid flow, and then the fifth driving mechanism 663 drives the second push rod 6624 to move in the opposite direction, so that the first valve 6623 closes to stop supplying air or liquid to the hollow structure of the core-passing nozzle 6611, and this process is repeated.

[0071] The fifth drive mechanism 663 can be implemented as a push-pull electromagnet, a pneumatic cylinder, an oil cylinder, an electric cylinder, a linear module, a motor, and a transmission mechanism. The fifth drive mechanism 663 drives the first push rod 6612 to reciprocate linearly via the second cam 6631, and the fifth drive mechanism 663 drives the second push rod 6624 to reciprocate linearly via the third cam 6632. The second cam 6631 and the third cam 6632 are typically mounted on a rotating shaft, which can be driven directly by an electric motor or the like, or by the electric motor or the like through a transmission mechanism such as a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism.

[0072] The fifth driving mechanism 663 drives the first push rod 6612 to reciprocate linearly through the second cam 6631. The end of the first push rod 6612 away from the core nozzle 6611 is provided with a first top wheel 6613 that cooperates with the second cam 6631. The first push rod 6612 is provided with a third spring 6614 and a shoulder or stopper that cooperates with the third spring 6614. The first push rod 6612 is installed on the frame 61. One end of the third spring 6614 presses against the shoulder or stopper of the first push rod 6612, and the other end of the third spring 6614 presses against the frame 61. During use, the fifth driving mechanism 663 drives the second cam 6631 to rotate, and the second cam 6631 drives the first push rod 6612 to reciprocate linearly. The compressed third spring 6614 can use its elastic restoring force to enable the first top wheel 6613 to always elastically press against the second cam 6631, ensuring that the first push rod 6612 and the second cam 6631 move synchronously. The structure is simple, stable, reliable and easy to operate.

[0073] The fifth drive mechanism 663 drives the second push rod 6624 in reciprocating linear motion via the third cam 6632. The first valve 6623 is a one-way valve for internal and external threads. A second top wheel 6625, which cooperates with the third cam 6632, is provided on the end of the second push rod 6624 away from the first valve 6623. A fourth spring 6626 and a shoulder or stopper that cooperates with the fourth spring 6626 are provided on the second push rod 6624. The principles are similar to those of the second cam 6631 and the first push rod 6612. The third cam 6632 drives the second push rod 6624 in reciprocating linear motion, opening and closing the valve core of the first valve 6623. The internal valve core and corresponding spring cooperate to press against the valve core, compressing the spring and opening the one-way valve. When the pressure on the valve core is removed, the spring pushes the valve core back, closing the one-way valve. A first push rod is provided at one end of the second push rod 6624 away from the second push wheel 6625 . The first push rod is located in the channel of the second support 6621 . The first push rod is more convenient for pressing the valve core of the first valve 6623 to open the first valve 6623 .

[0074] The core assembly 661 also includes a first rod sleeve 6615 that cooperates with the first push rod 6612. The fifth drive mechanism 663 drives the first push rod 6612 to perform reciprocating linear motion along the first rod sleeve 6615, providing smoother, more reliable, and more precise motion. The first push rod 6612 is provided with a limit slot along its axial direction. The first rod sleeve 6615 is provided with a threaded hole that corresponds to the limit slot. A limit screw extends through the threaded hole and into the limit slot, thereby limiting the movement of the first push rod 6612. Specifically, the length of the limit slot defines the maximum travel distance of the first push rod 6612 and also prevents the first push rod 6612 from separating from the first rod sleeve 6615. The assembly 6612 is simple and convenient to install.

[0075] The first push rod 6612 is provided with a groove body that cooperates with the first top wheel 6613. The groove body is provided with a pin shaft that is rotatably connected to the first top wheel 6613. One end of the first top wheel 6613 is located in the groove body and the other end extends out of the groove body to cooperate with the second cam 6631, making the structure more compact and stable.

[0076] The second push rod 6624 is provided with a limited slot along its axial direction. The second support 6621 is provided with a threaded hole that corresponds to the limited slot, similar to the structure of the first push rod 6612 and the first rod sleeve 6615 described above. The second push rod 6624 is provided with a slot body that mates with the second top wheel 6625. The slot body is provided with a pin that is rotatably connected to the second top wheel 6625. One end of the second top wheel 6625 is located in the slot body, and the other end extends outside the slot body to mate with the third cam 6632, resulting in a more compact and stable structure. The second support 6621 is also provided with a sealing ring and a sleeve for the second push rod 6624. The sealing ring prevents water leakage, and the sleeve can be a copper sleeve, etc., to ensure the smooth movement of the second push rod 6624, making it more stable and reliable.

[0077] Compared with the prior art, the advantages of the present invention are as follows: the lotus seeds to be processed are sequentially conveyed to the first conveying device 2 through the feeding device 3, the shelling device 4 first shells the lotus seeds conveyed on the first conveying device 2 one by one, and then the peeling device 5 peels the peeled lotus seeds one by one, and the peeled lotus seeds pass through the first discharge trough 53 and enter the feeding device 68 of the core-passing machine 6 one by one, and the feeding device 68 feeds the lotus seeds one by one into the first positioning section 626 of the second conveying device 62, and the vibration pressure straightening component 67 The lotus seeds on the conveyor chain 621 can be elastically vibrated and pressed, and the first roller 625 can be driven to rotate to align the lotus seeds in the first positioning zone 626. The detection component 63 first detects and identifies the lotus seeds conveyed on the second conveyor 62 in sequence, quickly and accurately determines the direction of the lotus seeds, and determines whether the lotus seeds are not completely shelled, not completely peeled, or damaged. Then, based on the detection results, the sorting component 64 removes the defective lotus seeds on the second conveyor 62. The removed defective lotus seeds can be sorted by the corresponding device. The lotus seeds are collected for subsequent processing, and then the steering device 65 redirects the lotus seeds on the second conveyor 62 that are not in the right direction, for example, by rotating the lotus seeds in the opposite direction by 180 degrees and placing them back on the second conveyor 62. Then, the two first rollers 625 for positioning the lotus seeds and the first pressing roller 675 use three rollers to center and press the lotus seeds to be cored. The core-passing assembly 661 of the core-passing device 66 then cores the lotus seeds on the second conveyor 62 in turn.
