Description

Technical Field

[0001] The present disclosure relates to lotus seed processing equipment, and in particular to a lotus seed 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

[0035] See also Figures 1 to 13 The figure schematically illustrates a lotus seed core-clearing machine according to the present disclosure, comprising a frame 1, on which are disposed a conveying device 2, a detection assembly 3, a sorting assembly 4, a steering device 5, and a core-clearing device 6. The conveying device 2 is used to sequentially convey lotus seeds to be processed. The detection assembly 3, sorting assembly 4, steering device 5, and core-clearing device 6 are sequentially arranged in correspondence with the conveying device 2. The detection assembly 3, sorting assembly 4, steering device 5, and core-clearing device 6 are sequentially arranged along the feeding direction of the conveying device 2. The frame 1 is connected to lotus seed shelling and peeling equipment via fasteners such as screws, allowing the lotus seed core-clearing machine to be installed entirely on the lotus seed shelling and peeling equipment, facilitating the automated and continuous processing of lotus seed shelling, peeling, and core-clearing.

[0036] The lotus seed core-clearing machine can be installed on lotus seed shelling and peeling equipment. The peeled lotus seeds enter the conveying device 2 through the corresponding feed trough. The lotus seeds to be cored are positioned and placed on the conveying device 2 for sequential transportation. The detection component 3 first detects and identifies the lotus seeds conveyed on the conveying device 2, quickly and accurately determines the direction of the lotus seeds, and determines whether the lotus seeds are defective such as incomplete shelling, incomplete peeling or damaged. Then, according to the detection results, the sorting component 4 knocks away the defective lotus seeds on the conveying device 2. The knocked away defective lotus seeds can be collected by the corresponding device for subsequent processing. Then, the steering device 5 redirects the lotus seeds in the wrong direction on the conveying device 2, for example, rotating the reversed lotus seeds 180° and placing them back on the conveying device 2. Then, the core-clearing device 6 performs core-clearing on the lotus seeds on the conveying device 2 in sequence. Finally, the conveying device 2 transports the cored lotus seeds to the corresponding box for collection, thereby realizing automatic core-clearing of lotus seeds.

[0037] The conveyor device 2 includes a conveyor chain 21, a first driving wheel 22, and a first driven wheel 23 that cooperate with the conveyor chain 21. The first driving wheel 22 is driven by a first drive mechanism 24. The first driving wheel 22 and the first driven wheel 23 cooperate to drive the conveyor chain 21. The conveyor chain 21 is formed by a plurality of first rollers 25 connected in sequence. The first rollers 25 are rotatable, and a first positioning area 201 is formed between two adjacent first rollers 25 to position lotus seeds. Each first positioning area 201 can accommodate only one lotus seed. The first drive mechanism 24 drives the first driving wheel 22 to rotate. The first driving wheel 22 and the first driven wheel 23 cooperate to drive the conveyor chain 21. Lotus seeds to be processed sequentially fall into the first positioning area 201, thereby positioning and conveying the lotus seeds to be processed. The first drive mechanism 24 can be driven directly by an electric motor or a motor, or can be driven by an electric motor or a motor via a transmission mechanism such as a belt drive, a chain drive, or a gear drive. The first drive mechanism 24 can also be driven by other suitable power mechanisms known in the art. The first roller 25 can be made entirely of a flexible material, or a roller with a flexible layer or a rubber-coated roller, such as a silicone roller, to better compress the lotus seeds and reduce damage. The first roller 25 has grooves along its circumference, typically located in the middle of the roller 25. This provides a more compact and stable structure, enabling more stable and reliable compression of the lotus seeds.

[0038] A first feeding device 8 is also provided on the frame. The first feeding device 8 is located above the feeding end of the conveying device. The first feeding device 8 is a structure in the prior art and is not described in detail here. The first feeding device 8 usually includes a feeding hopper and a turntable driven by a driving mechanism such as a motor. The turntable is provided with positioning grooves for positioning lotus seeds along its circumferential direction. Each positioning groove can only accommodate one lotus seed. The peeled lotus seeds enter the feeding hopper through the corresponding feeding groove. The lotus seeds in the feeding hopper enter the positioning grooves on the turntable one by one through the vibrating baffle mechanism. Then the turntable rotates, and the lotus seeds are fed one by one into the first positioning interval 201 on the conveying device 2.

[0039] A vibration and pressure straightening component 7 is provided between the steering device 5 and the core-passing device 6 and / or at the end of the detection component 3 away from the sorting component 4. Usually, a vibration and pressure straightening component 7 is provided between the steering device 5 and the core-passing device 6 and at the end of the detection component 3 away from the sorting component 4, that is, the transported lotus seeds are first vibrated and straightened, and then the detection component 3 detects the lotus seeds. After the steering device 5 diverts the lotus seeds, the transported lotus seeds are vibrated and straightened again, and then the core-passing device 6 performs core processing on the lotus seeds.

[0040] The vibration-pressure straightening assembly 7 includes a first support plate 71 and an elastic pressure block 72. The elastic pressure block 72 is mounted on a corresponding bracket. Both the bracket and the first support plate 71 are mounted on the frame 1. The first support plate 71 is located below the conveyor chain 21 to support the conveyor chain 21. The elastic pressure block 72 is fixedly arranged above the first support plate 71 and moves above the conveyor chain 21. Two first limiting bars 73 and a bracket for accommodating the two first limiting bars 73 are also symmetrically provided on the first support plate 71. The elastic pressure block 72 is generally located above and between the two first limiting bars 73. The length direction of the elastic pressure block 72 is consistent with the length direction of the two first limiting bars 73. The conveyor chain 21 is conveyed along the first support plate 71 and passes between the two first limiting strips 73 and under the elastic pressure block 72. The lotus seeds are positioned in the first positioning interval 201 on the conveyor chain 21 in sequence. The two first limiting strips 73 can prevent the roller chain from deflecting. The friction between the elastic pressure block 72 and the conveyor chain 21 can drive the first roller 25 to rotate. The interaction between the elastic pressure block 72 and the conveyor chain 21 can make the elastic pressure block 72 vibrate to elastically vibrate and press the lotus seeds, so that the lotus seeds in the first positioning interval 201 can also make the lotus seeds standing in the first positioning interval 201 level, so that the lotus seeds that are skewed, misaligned, or standing in the first positioning interval 201 can be leveled and straightened, which is convenient for subsequent direction identification and core processing of the lotus seeds.

[0041] The elastic pressing block 72 can be made of an elastic material such as rubber, urethane foam, or silicone, for example, a silicone pressing block. A curved guide surface is provided at the feed end of the elastic pressing block 72 to mate with the lotus seeds. The first guide surface can be an inclined surface or other appropriately shaped curved surface. The guide surface guides the lotus seeds on the conveyor chain 21, facilitating their entry beneath the elastic pressing block 72 and allowing for the placement of upright lotus seeds, thereby providing greater stability and reliability.

[0042] First grooves 731 for cooperating with the conveyor chain 21 are respectively provided on the opposite sides of the two first limit bars 73. The conveyor chain 21 passes between the two first limit bars 73 along the first support plate 71. At the same time, the two sides of the conveyor chain 21 pass along the two first grooves 731 respectively, thereby preventing the roller chain from deviating, shaking up and down, etc., and the structure is more compact, stable, and reliable.

[0043] Regarding the vibration and pressure straightening assembly 7 disposed between the steering device 5 and the core-passing device 6, a first pressure roller 75 is provided above the first support plate 71 for cooperating with the core-passing device 6. The conveyor chain 21 passes along the first support plate 71 between the two first limiting bars 73, and simultaneously passes under the elastic pressure block 72 and the first pressure roller 75 in sequence. The first pressure roller 75 can compress the lotus seeds in the first positioning section 201 below. That is, the two first rollers 25 for positioning the lotus seeds and the first pressure roller 75 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 6 then cores the lotus seeds. The first pressure roller 75 is mounted on a fourth bracket 74. The fourth bracket 74 is provided with a pin or a rotating shaft connected to the first pressure roller 75. The first pressure roller 75 can also rotate freely. The first pressure roller 75 is substantially the same as the first roller 25, and the structure of the first roller 25 described above is referred to. The two first limit bars 73 are respectively provided with first avoidance grooves 732 for cooperating with the core-passing device 6. The two first avoidance grooves 732 correspond to each other. The first support plate 71 can also be provided with a core receiving bucket 77 for cooperating with the core-passing device 6. The lotus core passed out is collected and processed by the corresponding collecting device along the core receiving bucket 77.

[0044] The first support plate 71 is provided with a friction plate 76 for cooperating with the conveyor chain 21. The friction plate 76 is located between the two first limit bars 73. The conveyor chain 21 passes between the two first limit bars 73 and above the friction plate 76. The friction plate 76 can increase the friction between the first roller 25 and the first roller 25, facilitating better rotation of the first roller 25 and better elastic vibration and pressure of the elastic pressure block 72 on the lotus seeds, thereby better aligning the lotus seeds. The friction plate 76 can be made of the same material as the elastic pressure block 72, such as a silicone plate, or other suitable material plates. The friction plate 76 is provided with a friction structure for cooperating with the first roller 25. 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.

[0045] The detection component 3 includes a first bracket 31, on which is disposed at least one first camera 32 for detecting lotus seeds. The first camera 32 can be one, two, or more, and the number and arrangement of the first cameras 32 are determined according to specific circumstances. Figure 4 As shown, two first cameras 32 are symmetrically arranged on the first bracket 31. These cameras 32 can detect and identify the lotus seeds in the middle from both sides. Lotus seeds are sequentially placed on the conveyor chain 21 of the conveyor device 2 for transport. The two first cameras 32, located on either side of the conveyor chain 21, can comprehensively detect and identify the lotus seeds from both the head and tail, providing higher accuracy, stability, and reliability. Furthermore, more first cameras 32 can be used to detect and identify lotus seeds from different directions.

[0046] The first camera 32 is a camera, such as a high-speed camera, a CCD camera, a CMOS camera, etc., which can more accurately and comprehensively photograph and detect the lotus seeds. The first bracket 31 is provided with two first reflectors 33 that cooperate with the first camera 32 and a first fixing plate 34 on which the two first reflectors 33 are respectively placed. The two first reflectors 33 are symmetrically located on either side of the first camera 32. The first reflectors 33 can be made of reflective mirrors, plane reflectors, spherical reflectors, and aspherical reflectors. The two first reflectors 33 reflect, allowing the first camera 32 to more accurately and comprehensively photograph and detect the lotus seeds. There is no need to set up multiple cameras to take pictures from different directions, resulting in a simpler structure and more convenient operation. The two first reflectors 33 are usually symmetrically located on either side in front of the first camera 32, which has higher detection accuracy and better results. The first bracket 31 can also be provided with reinforcing ribs and a light source that cooperates with the first camera 32.

[0047] The sorting assembly 4 includes a first removal rod 41 and a second drive mechanism 42. The second drive mechanism 42 is mounted on a third bracket 43, which is mounted on the frame 1 via fasteners such as screws. The second drive mechanism 42 drives the first removal rod 41 to move, which can be reciprocating linear motion or rotational motion. The first removal rod 41 and the second drive mechanism 42 can be one group, two groups, or multiple groups. Based on the detection results of the detection assembly 3, the second drive mechanism 42 drives the first removal rod 41 to move, which can knock out defective lotus seeds in the corresponding position. The knocked-out 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 1 is also provided with a sorting hopper 12 that corresponds to the sorting assembly 4. The knocked-out lotus seeds enter the corresponding collection device through the sorting hopper 12.

[0048] The head of the first removing rod 41 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 41 to increase the contact area, etc.

[0049] The second driving mechanism 42 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 2 、 Figure 13 As shown, the first driving mechanism 24 adopts a motor, and the first removing rod 41 is located above the conveyor chain 21. One end of the first removing rod 41 is fixedly connected to the output shaft of the motor. The motor drives the first removing rod 41 to rotate to knock off the defective lotus seeds on the conveyor chain 21. 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 41, 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 second driving mechanisms 42. The more than two second driving mechanisms 42 can be arranged side by side or arranged up and down. The second driving mechanisms 42 correspond to the first removing rods 41 one by one. Lotus seeds with different defects correspond to different second driving mechanisms 42 and first removing rods 41. 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 second driving mechanisms 42 and first removing rods 41 separately. Lotus seeds with similar defects that can be processed together can also share a set of second driving mechanisms 42 and first removing rods 41. More than two second driving mechanisms 42 can separately drive the first removing rods 41 that cooperate 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.

[0050] like Figure 3As shown, the second drive mechanism 42 is an electromagnet, and the first removal rod 41 is located on one side of the lotus seeds on the conveyor chain 21. The electromagnet pushes the first removal rod 41 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 of the magnetism can be changed, the presence of magnetism can be controlled, and the direction of the magnetic pole can be changed, making it very easy to control and adjust. As mentioned above, the electromagnet corresponds to the first removal rod 41 one-to-one. The electromagnet and the first removal rod 41 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.

[0051] The steering device 5 includes a feeding assembly 51, a fourth drive mechanism 52, and a fifth drive mechanism 53. The fourth drive mechanism 52 and the fifth drive mechanism 53 are mounted on the frame 1. The feeding assembly 51 is connected to the fifth drive mechanism 53, and the fourth drive mechanism 52 is connected to the fifth drive mechanism 53. During use, if lotus seeds on the conveyor 2 are not in the right direction, the fourth drive mechanism 52 drives the feeding assembly 51 and the fifth drive mechanism 53 to move up and down together, so that the feeding assembly 51 picks up the lotus seeds on the conveyor 2. Then, the fifth drive mechanism 53 drives the feeding assembly 51 to rotate, so that the lotus seeds picked up by the feeding assembly 51 are redirected, for example, rotating the reversed lotus seeds 180 degrees, and then placing the redirected lotus seeds back on the conveyor 2, thereby achieving the redirection of the lotus seeds. This is convenient to operate, has a simplified structure, is highly accurate, and is highly efficient, facilitating subsequent core processing of the lotus seeds.

[0052] The material picking assembly 51 includes a first connecting rod 511, the upper end of the first connecting rod 511 is connected to the fifth driving mechanism 53, the lower end of the first connecting rod 511 is provided with a material picking portion 512 for picking up materials and a first fixing sleeve 513 for fixing the material picking portion 512, the fifth driving mechanism 53 is arranged on the second bracket 54, the second bracket 54 is installed on the frame 1, the second bracket 54 is provided with a stripping plate 543 that cooperates with the first fixing sleeve 513, the stripping plate 543 is provided with a first through hole 5431 that cooperates with the first fixing sleeve 513, the diameter of the first through hole 5431 is smaller than the diameter of the lotus seed, and the diameters of the first connecting rod 511 and the first fixing sleeve 513 are also smaller than the diameter of the first through hole 5431. The material taking part 512 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 fourth driving mechanism 52 drives the material picking assembly 51 and the fifth driving mechanism 53 to move up and down together, so that the material picking part 512 picks up the lotus seeds from the first positioning interval 201. After the fifth driving mechanism 53 drives the material picking assembly 51 to rotate to complete the turning of the lotus seeds, the fourth driving mechanism 52 continues to drive the material picking assembly 51 and the fifth driving mechanism 53 to move upward together. As the first fixing sleeve 513 passes through the first through hole 5431 upward, since the size of the lotus seeds is larger than the first through hole 5431, the stripping plate 543 can block the lotus seeds, causing the lotus seeds to fall off from the material picking part 512 and fall back into the first positioning interval 201, thereby realizing the discharge of the lotus seeds after turning. The structure is simple, stable and reliable.

[0053] The stripping plate 543 can be made of metal plate, plastic plate or other suitable materials. A flexible pressing plate 544 is arranged below the stripping plate 543, such as silicone skin, rubber skin, etc. The pressing plate 544 is tilted and can swing up and down. The upper end of the pressing plate 544 is close to the feed end and is connected to the stripping plate 543, for example, it is fixedly connected or hinged with fasteners such as screws. The lower end of the pressing plate 544 is close to the discharge end and is suspended in the air. A second through hole 5441 is provided on the pressing plate 544 to match the first fixed sleeve 513. The diameter of the second through hole 5441 is smaller than the diameter of the lotus seed. The second through hole 5441 is coaxial with the first through hole 5431 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 544 can block and limit the corresponding lotus seeds, prevent the lotus seeds from jumping, and ensure that the feeding part 512 can pick up the lotus seeds more stably. As the feeding assembly 51 and the lotus seeds move upward, the lotus seeds can drive the flexible pressing plate 544 to swing upward synchronously until the flexible pressing plate 544 is attached to the bottom surface of the stripping plate 543, and then the lotus seeds are stripped by the restriction of the stripping plate 543. The flexible pressing plate 544 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 544 can also be made of a metal plate, a plastic plate, or an elastic plate. The upper end of the pressing plate 544 is close to the feeding end and is hinged to the stripping plate 543, and the lower end of the pressing plate 544 is close to the discharging end and is suspended.

[0054] The bottom surface of the first connecting rod 511 is provided with a first slide 5111 along the vertical direction, which cooperates with the upper end of the first fixing sleeve 513; the first connecting rod 511 is provided with a first limiting long groove 5112 along the vertical direction, which is connected to the first slide 5111; a first spring 514 is provided in the first slide 5111; the upper end of the first spring 514 presses against the top of the first slide 5111; the lower end of the first spring 514 presses against the top of the first fixing sleeve 513; the first fixing sleeve 513 is provided with a first hole body 5131 which can correspond to the first limiting long groove 5112; the first limiting member 515 passes through the first limiting long groove 5112 and the first hole body 5131, that is, one end of the first limiting member 515 is connected to the first fixing sleeve 513 and the other end thereof is located in the first limiting long groove 5112. When the feeding portion 512 moves downward to retrieve lotus seeds, the lotus seeds exert a certain reverse force on the feeding portion 512, causing the first fixing sleeve 513 to slide upward along the first slideway 5111 and the first stopper 515 to simultaneously slide upward along the first stopper slot 5112. The first spring 514 is compressed, thereby providing buffering protection for the feeding. The first spring 514 can also push the first fixing sleeve 513 and the feeding portion 512 to automatically reset. The first stopper slots 5112 can be symmetrically provided on both sides of the first connecting rod 511. The first hole 5131 can be a threaded hole or a through hole, and the first stopper 515 can be a screw or a pin, resulting in a simple structure and more convenient operation.

[0055] The first fixing sleeve 513 includes a connecting rod and a chuck. The first hole 5131 is provided at the upper end of the connecting rod. 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 material taking part.

[0056] The fifth drive mechanism 53 is a motor with its output end facing downward and connected to the retrieving assembly 51. The motor is mounted on a first support 532. The fourth drive mechanism 52 is connected to the first support 532. Typically, the motor's output shaft is coaxially connected to the first connecting rod 511 of the retrieving assembly 51. The fourth drive mechanism 52 drives the first support 532 to move up and down, causing the fifth drive mechanism 53 and the retrieving assembly 51 to move up and down as a whole. The motor drives the retrieving assembly 51 to rotate, causing the lotus seeds picked up by the retrieving assembly 51 to be diverted. The fifth drive mechanism 53 can also be a rotary cylinder, a rotating table, or other suitable power mechanism known in the art.

[0057] A first guide mechanism 541 is vertically mounted on the second bracket 54 to cooperate with the first support 532. The fourth drive mechanism 52 drives the first support 532 to move up and down, while the first support 532 simultaneously moves up and down along the first guide mechanism 541, providing more stable and reliable movement. The first guide mechanism 541 may be a linear slide, or a structure of a slider and a slide groove.

[0058] The fourth drive mechanism 52 can use a pneumatic cylinder, an oil cylinder, an electric cylinder, a linear module, etc. to drive the fifth drive mechanism 53 to move up and down. The fourth drive mechanism 52 can also drive the fifth drive mechanism 53 to move up and down through a pull rod assembly 55, etc. The pull rod assembly 55 includes a first rotating shaft 551, a first swing rod 552, and a first pull rod 553. One end of the first swing rod 552 is fixedly connected to the first rotating shaft 551 and the other end thereof cooperates with the fourth drive mechanism 52. One end of the first pull rod 553 is fixedly connected to the first rotating shaft 551 and the other end thereof is connected to the first support 532 of the fifth drive mechanism 53 via a first chain 555. That is, one end of the first chain 555 is connected to the first pull rod 553 and the other end thereof is connected to the first support 532 of the fifth drive mechanism 53, for example, by a hinged pin, etc. The fourth drive mechanism 52 drives the first swing arm 552 to swing, which in turn drives the first rotating shaft 551 to rotate synchronously. The first rotating shaft 551 then drives the first pull rod 553 to swing synchronously, causing the first chain 555 to pull the first support 532 of the fifth drive mechanism 53 to move up and down along the first guide mechanism 541. The first chain 555 is a flexible connection, providing greater flexibility, stability, and reliability. Alternatively, the first chain 555 can be replaced by a connecting rod, one end of which is hinged to the first pull rod 553 and the other end of which is hinged to the first support 532 of the fifth drive mechanism 53.

[0059] The fourth drive mechanism 52 drives the first swing arm 552 to swing via the first cam 521. The first swing arm 552 is provided with a first pulley 554 that cooperates with the first cam 521. The fifth drive mechanism 53's own gravity maintains the first pulley 554 in constant contact with the first cam 521. The fourth drive mechanism 52 drives the first cam 521 to rotate, which in turn drives the first swing arm 552 to swing via the first pulley 554. The first cam 521 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 fourth drive mechanism 52 can also utilize a pneumatic cylinder, oil cylinder, electric cylinder, or the like to directly drive the first swing arm 552 to swing.

[0060] The second bracket 54 is provided with a first electromagnet 545 and a first connecting plate 542 for mounting the first electromagnet 545 . The first support 532 is provided with a second connecting plate 533 corresponding to the first electromagnet 545 . The second connecting plate 533 is a magnetic plate. The first electromagnet 545 is located above the second connecting plate 533 . During use, for lotus seeds with the correct direction and no need to turn, when the fifth drive mechanism 53 and the material taking component 51 are in a high position, the first electromagnet 545 is energized, and the first electromagnet 545 magnetically attracts the second connecting plate 533, so that the fifth drive mechanism 53 and the material taking component 51 are fixed in a high position as a whole. Since the first chain 555 is a soft connection and can bend freely, the fourth drive mechanism 52 drives the pull rod component 55 to move through the first cam 521. At this time, only the first chain 555 is bent, etc., and cannot drive the fifth drive mechanism 53 and the material taking component 51 to move downward together, that is, the material taking component 51 cannot move downward to take material, thereby preventing the material taking component 51 from taking lotus seeds that do not need to be turned, reducing damage to the lotus seeds, etc.

[0061] The first connecting plate 542 and the second connecting plate 533 are connected by a second spring 531. The second spring 531 is arranged in the vertical direction. The first connecting plate 542 is located above the second connecting plate 533. The upper end of the second spring 531 is connected to the first connecting plate 542 and the lower end is connected to the second connecting plate 533, such as by welding or by setting screws on the first connecting plate 542 and the second connecting plate 533 respectively and inserting them into the two ends of the second spring 531. The number and arrangement of the second springs 531 depend on the specific situation. Usually, there are more than two second springs 531 symmetrically or evenly distributed. The second springs 531 have the functions of buffering protection and elastically supporting the fifth driving mechanism 53, and the structure is more stable and reliable.

[0062] The core-passing device 6 comprises a core-passing assembly 61, a punch assembly 62, and a third drive mechanism 63. The core-passing assembly 61 has a hollow, thin, needle-shaped core-passing nozzle 611, also known as a core-passing needle. The punch assembly 62 is connected to the core-passing nozzle 611 via a pipeline and is typically connected to a supply device such as a water pump, air pump, or spray pump. The punch assembly 62 can be controlled by a separate hydraulic or air system. Alternatively, the punch assembly 62 can be driven by the third drive mechanism 63. In other words, the core-passing assembly 61 and the punch assembly 62 can share the third drive mechanism 63, resulting in a simpler, more compact, and energy-efficient structure.

[0063] During use, the two first rollers 25 for positioning the lotus seeds and the first pressing wheel 75 form a three-axis centering structure, thereby pressing and fixing the lotus seeds to be cored. The core punch assembly 62 is connected to the core-passing nozzle 611 through a pipeline. The third driving mechanism 63 can drive the core-passing assembly 61 to move, so that the hollow core-passing nozzle 611 performs core-passing processing on the lotus seeds positioned and pressed on the conveying device 2. The lotus core that is passed out is usually at least partially located in the core-passing nozzle 611. As the core-passing nozzle 611 passes the lotus core out, the third driving mechanism 63 can simultaneously drive and control the core punch assembly 62 to supply air or liquid, such as water, compressed air, etc., to the hollow core-passing nozzle 611, and the lotus core is flushed out of the core-passing nozzle 611 through the pressurized or high-pressure air or liquid flow, thereby completing the core-passing processing of the lotus seeds and simultaneously clearing the lotus core in the core-passing nozzle 611, facilitating efficient and automated core-passing processing of lotus seeds, and not easily causing the core-passing nozzle 611 to be blocked. The stability and reliability are high, thereby improving the processing quality and yield of the lotus seeds.

[0064] The core-passing assembly 61 includes a first push rod 612 and a core-passing nozzle 611. The core-passing nozzle 611 is arranged at one end of the first push rod 612. The third driving mechanism 63 cooperates with the end of the first push rod 612 away from the core-passing nozzle 611. The first push rod 612 is provided with a first connector 616 connected to the core-passing nozzle 611, such as a quick water pipe connector, a quick air pipe connector, a pagoda connector, etc. The first connector 616 is connected to the core punch assembly 62 through a pipeline. One end of the core-passing nozzle 611 is usually provided with a connector threadedly connected to the first push rod 612. A channel connected to the core-passing nozzle 611 and the first connector 616 is provided in the first push rod 612. During use, the third driving mechanism 63 drives the first push rod 612 to move back and forth linearly, so that the core-passing nozzle 611 can pass the lotus seeds positioned on the conveying device 2, and as the core-passing nozzle 611 passes the lotus core out, the third driving mechanism 63 simultaneously drives the control core punch assembly 62 to supply air or liquid to the hollow core-passing nozzle 611 through the first joint 616, and the lotus core is flushed out of the core-passing nozzle 611 by means of pressurized or high-pressure air or liquid flow.

[0065] The punch assembly 62 includes a second support 621, which is provided with a passage, a second push rod 624, a second connector 622, and a first valve 623. The second connector 622 and the first valve 623 are respectively connected to the passage. The second connector 622 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 623 is connected to the core-clearing nozzle 611 via a pipeline. During use, as the core-clearing nozzle 611 releases the lotus seed, the third drive mechanism 63 simultaneously drives the second push rod 624 in a linear motion, causing the first valve 623 to open and supply air or liquid to the hollow core-clearing nozzle 611. The pressurized or high-pressure air or liquid flow flushes the lotus seed from the core-clearing nozzle 611. The third drive mechanism 63 then drives the second push rod 624 in a reverse motion, causing the first valve 623 to close, stopping the air or liquid supply to the hollow core-clearing nozzle 611. This process repeats in a continuous cycle.

[0066] The third drive mechanism 63 can be implemented as a push-pull electromagnet, air cylinder, oil cylinder, electric cylinder, linear module, motor, and transmission mechanism. The third drive mechanism 63 drives the first push rod 612 to reciprocate linearly via the second cam 631, and the third drive mechanism 63 drives the second push rod 624 to reciprocate linearly via the third cam 632. The second cam 631 and the third cam 632 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.

[0067] The third driving mechanism 63 drives the first push rod 612 to reciprocate linearly through the second cam 631. The end of the first push rod 612 away from the core nozzle 611 is provided with a first top wheel 613 that cooperates with the second cam 631. The first push rod 612 is provided with a third spring 614 and a shoulder or stopper that cooperates with the third spring 614. The first push rod 612 is mounted on the frame 1. One end of the third spring 614 presses against the shoulder or stopper of the first push rod 612, and the other end of the third spring 614 presses against the frame 1. During use, the third driving mechanism 63 drives the second cam 631 to rotate, and the second cam 631 drives the first push rod 612 to reciprocate linearly. The compressed third spring 614, through its elastic restoring force, can keep the first top wheel 613 elastically pressed against the second cam 631, ensuring that the first push rod 612 and the second cam 631 move synchronously. The structure is simple, stable, reliable, and easy to operate.

[0068] The third drive mechanism 63 drives the second push rod 624 to reciprocate linearly via the third cam 632. The first valve 623 is a one-way valve for internal and external threads. A second top wheel 625 is provided at the end of the second push rod 624, away from the first valve 623, and cooperates with the third cam 632. A fourth spring 626 and a shoulder or stopper that cooperates with the fourth spring 626 are provided on the second push rod 624. The principles are similar to those of the second cam 631 and the first push rod 612. The third cam 632 drives the second push rod 624 to reciprocate linearly, thereby opening and closing the valve core of the first valve 623. The one-way valve for internal and external threads is a common structure in the prior art. The internal valve core cooperates with a corresponding spring, pressing against the valve core and compressing the spring, causing the one-way valve for internal and external threads to open. When the pressure on the valve core is removed, the spring pushes the valve core back to its original position, causing the one-way valve for internal and external threads to close. A first push rod is provided at one end of the second push rod 624 away from the second push wheel 625 . The first push rod is located in the channel of the second support 621 . The first push rod is more convenient for pressing the valve core of the first valve 623 to open the first valve 623 .

[0069] The core assembly 61 also includes a first rod sleeve 615 that cooperates with the first push rod 612. The third drive mechanism 63 drives the first push rod 612 to perform reciprocating linear motion along the first rod sleeve 615, which provides smoother, more reliable, and more precise motion. The first push rod 612 is provided with a limit slot along its axial direction. The first rod sleeve 615 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 612. Specifically, the length of the limit slot defines the maximum travel distance of the first push rod 612 and also prevents the first push rod 612 from separating from the first rod sleeve 615. Installation is simple and convenient.

[0070] The first push rod 612 is provided with a groove body that cooperates with the first top wheel 613. The groove body is provided with a pin shaft that is rotatably connected to the first top wheel 613. One end of the first top wheel 613 is located in the groove body and the other end extends out of the groove body to cooperate with the second cam 631. The structure is more compact and stable.

[0071] The second push rod 624 is provided with a limited slot along its axial direction, and the second support 621 is provided with a threaded hole corresponding to the limited slot, similar to the structure of the first push rod 612 and the first rod sleeve 615 described above. The second push rod 624 is provided with a slot body that cooperates with the second top wheel 625. The slot body is provided with a pin that is rotatably connected to the second top wheel 625. One end of the second top wheel 625 is located in the slot body, and the other end extends outside the slot body to cooperate with the third cam 632, resulting in a more compact and stable structure. The second support 621 is also provided with a sealing ring and a sleeve for the second push rod 624. The sealing ring can prevent water leakage, and the sleeve can be a copper sleeve, etc., to ensure the smooth movement of the second push rod 624, making it more stable and reliable.

[0072] Alternatively, the first feeding device 8, conveying device 2, vibratory pressure and straightening assembly 7, detection assembly 3, sorting assembly 4, steering device 5, and core-clearing device 6 may be provided in two sets, one on each side of the frame 1. This means that the lotus seed core-clearing machine has a duplex structure. Alternatively, the conveying device 2, steering device 5, and core-clearing device 6 may share a single drive mechanism, each of which drives the conveying device 2, steering device 5, and core-clearing device 6. This results in a more compact, robust, and smaller structure, providing greater stability and reliability. A waterproof cover 11 is also provided on the frame, housing the first feeding device 8, conveying device 2, vibratory pressure and straightening assembly 7, detection assembly 3, sorting assembly 4, steering device 5, and core-clearing device 6 for enhanced safety and reliability.

[0073] Compared with the prior art, the advantages of the present invention are as follows: the lotus seeds to be processed are positioned and placed on the conveying device 2 for sequential transportation; the vibration and pressure straightening component 7 first performs vibration and pressure straightening on the conveyed lotus seeds; then the detection component 3 first detects and identifies the lotus seeds conveyed on the conveying device 2, quickly and accurately determines the direction of the lotus seeds, and determines whether the lotus seeds have defects such as incomplete shelling, incomplete peeling, or damage; then, based on the detection results, the sorting component 4 knocks off the defective lotus seeds on the conveying device 2; the knocked off defective lotus seeds can be collected by corresponding devices for subsequent processing; then the steering device 5 redirects the lotus seeds in the wrong direction on the conveying device 2, for example, rotates the reversed lotus seeds 180° and places them back on the conveying device 2; then the vibration and pressure straightening component 7 performs straightening again The conveyed lotus seeds are vibrated and straightened, and then the two first rollers 25 for positioning the lotus seeds and the first pressing wheel 75 are used to press and fix the lotus seeds to be cored through three-roller centering. The core-clearing device 6 then cores the pressed and fixed lotus seeds in turn. Finally, the conveying device 2 conveys the cored lotus seeds to corresponding boxes for collection, thereby realizing automatic core-clearing of lotus seeds. Moreover, the lotus seed core-clearing machine can be installed on lotus seed shelling and peeling equipment, etc., to facilitate the automatic and continuous processing of lotus seed shelling, peeling and core-clearing. The lotus seed core-clearing machine is easy to operate, has a simple, compact and stable structure, a small size, high precision and high efficiency, and is not prone to missed picking or wrong picking, thereby improving the stability and reliability of the equipment as well as the processing quality and yield of lotus seeds, reducing costs, and meeting increasingly high production needs.
