As the screening and transportation continue, the pecans with a large amount of screening will quickly fill up the first loading area or the second loading area. When the radar level sensor detects that the pecans in the corresponding area are accumulated to a set height, the telescopic plate corresponding to the area rotates to connect the area with the third loading area, thereby increasing the loading amount of pecans of corresponding quality.

[0031] 3. When the double-layer vibrating screen of the present invention is vibrating and conveying, the driving roller is in the slot hole and does not contact the inner wall of the slot hole, thereby avoiding collision between the double-layer vibrating screen and the driving roller.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Reference Figures 1 to 10The present embodiment discloses a processing production line for fresh pecans, comprising a first elevator 1, a cleaning machine 2, a second elevator 3, a blowing device 4, a vibrating conveyor 5, a third elevator 6, a loading conveyor 7, a plurality of drying boxes 8, a fourth elevator 9, a vibrating feeder 10 and an X-ray sorter 11 arranged in sequence according to the process. The output end of the first elevator 1 is located on the upper side of the cleaning machine 2. The pecans are transported by the first elevator 1 into the cleaning machine 2 for cleaning to remove impurities attached to the surface of the pecans. The feeding end of the second elevator 3 is arranged in the cleaning machine 2, and the discharging end of the second elevator 3 is located on the feeding side of the vibrating conveyor 5. The blowing device 4 is installed on the second elevator 3. The cleaned pecans are transported obliquely upward by the second elevator 3 and separated from the cleaning liquid. The blowing device 4 blows out hot air to preliminarily dry the transported pecans to remove surface moisture. The preliminarily dried pecans enter the vibrating conveyor 5 for screening.

[0046] Reference Figures 1 to 7 The vibrating conveyor 5 includes a double-layer vibrating screen 51 and a fixed frame 52. The double-layer vibrating screen 51 includes a vibrating screen body 511. A first sieve plate 512 and a second sieve plate 513 are fixedly installed on the vibrating screen body 511. The first sieve plate 512 is located directly above the second sieve plate 513 and the mesh number of the first sieve plate 512 is smaller than the mesh number of the second sieve plate 513. The first sieve plate 512 and the second sieve plate 513 divide the screen box of the vibrating screen body 511 into an upper area 514, a middle area 515 and a lower area 516. The upper area 514 corresponds to high-quality pecans, the middle area 515 corresponds to ordinary pecans, and the volume is slightly smaller than that of high-quality pecans. The lower area 516 is unqualified pecans, and the volume obviously does not meet the requirements. The upper area 514, the middle area 515 and the lower area 516 are all connected and installed with corresponding discharge hoppers 517.

[0047] The conveying area of ​​the third elevator 6 is divided into a right conveying area 61 and a left conveying area 62. The discharge hopper 517 corresponding to the upper area 514 conveys pecans to the right conveying area 61, and the discharge hopper 517 corresponding to the middle area 515 conveys pecans to the left conveying area 62, thereby realizing synchronous conveyance of pecans of different qualities by different zones.

[0048] Two groups of through holes 53 are provided on the side of the vibration screen body 511, one end of the through hole 53 is connected to the slot 54 provided therein and is located on the feeding side of the vibration screen body 511, two groups of sealing plates 55 are slidably connected to the side of the vibration screen body 511, corresponding to the through holes 53 respectively, and the double-layer vibration screen 51 also includes a plurality of elastic members 56, one end of the elastic member 56 is fixedly connected to the vibration screen body 511, and the other end is fixedly connected to the sealing plate 55, and the elastic member 56 is used to push the sealing plate 55 to slide on the vibration screen body 511, so that the sealing plate 55 blocks the through hole 53 to prevent pecans from flying out of the through hole 53 during transportation.

[0049] A dual-axis manipulator 57 is installed on the fixed frame 52. The dual-axis manipulator 57 includes an electric slide 571 fixedly installed on the fixed frame 52. The installation direction of the electric slide 571 is parallel to the conveying direction of the pecans. A fixed plate 572 is fixedly installed on the output end of the electric slide 571. The fixed plate 572 is slidably connected to the fixed frame 52. A first cylinder 573 is fixedly installed on the fixed plate 572. A connecting frame 574 is fixedly installed on the output shaft of the first cylinder 573. The connecting frame 574 is slidably connected to the fixed plate 572. Two sets of driving rollers 58 and a first gear 583 are rotatably installed on the connecting frame 574. The two sets of driving rollers 58 are inserted into the vibrating screen body 511 and are respectively located at Below the first sieve plate 512 and the second sieve plate 513, the driving roller 58 moves in the through hole 53 or the slot hole 54, and a plurality of flexible belts 581 are fixedly mounted on the driving roller 58. A second gear 582 is fixedly mounted on the driving roller 58, and the two second gears 582 are meshed with the first gear 583 for transmission. A lifting frame 59 is slidably connected to the fixed frame 52, and the connecting frame 574 is slidably connected to the lifting frame 59 through a guide rail 575, and the lifting frame 59 is located on the upper side of the connecting frame 574. When the connecting frame 574 rises or falls, the lifting frame 59 follows the rise and fall, and a rack 591 is fixedly mounted on the lifting frame 59, and the rack 591 is meshed with a second gear 582 for transmission. Through the arrangement of the first gear 583, the second gear 582 and the rack 591, when the driving roller 58 moves from the slot hole 54 to the through hole 53, the driving roller 58 will push the sealing plate 55 to rise, and the through hole 53 will open. When the driving roller 58 moves in the through hole 53, the second gear 582 meshes with the rack 591 and the first gear 583 for transmission, thereby realizing the automatic rotation of the two sets of driving rollers 58. The flexible belt 581 on the driving roller 58 will naturally unfold during the rotation process, thereby quickly slapping the first screen plate 55. 12 and the bottom of the second sieve plate 513, the pecans stuck in the sieve holes of the first sieve plate 512 and the second sieve plate 513 are pushed out, so that the pecans are quickly cleaned, which greatly reduces the difficulty of cleaning the pecans stuck in the sieve holes. During vibration conveying, the driving roller 58 moves from the through hole 53 to the slot 54, and the driving roller 58 does not contact the vibration screen body 511. At this time, the sealing plate 55 descends under the action of the elastic member 56, thereby blocking the through hole 53 to prevent the pecans from flying out of the through hole 53 during vibration conveying.

[0050] It should be noted that the driving roller 58 may also be a roller body with power, which can realize autonomous rotation.

[0051] Reference Figure 1 , Figures 8 to 10The loading conveyor 7 includes a monorail trolley 71 and a loading box 72 fixedly installed at the output end of the monorail trolley 71. The loading box 72 is slidably arranged on a track frame 711. The track frame 711 is located above a plurality of drying boxes 8 and one end is fixedly installed on the drying boxes 8. A partition 73 is fixedly installed in the loading box 72. Two groups of telescopic plates 74 are installed in the loading box 72. The telescopic plates 74 are composed of a sleeve plate and an extension plate that are slidably connected to each other. The sleeve plate is rotatably connected to the loading box 72. Two groups of second cylinders 75 are fixedly installed on the partition 73. A connecting rod 76 is fixedly connected to the output end of the second cylinder 75. The connecting rod 76 is slidably connected to the partition 73. The bottom of the connecting rod 76 The extension plate 74 is rotatably connected to the partition 73 and the two groups of telescopic plates 74, which divide the loading box 72 into a first loading area 77, a second loading area 78 and a third loading area 79. The telescopic plate 74 is used to control the connection between the first loading area 77 or the second loading area 78 and the third loading area 79. The discharge end of the third elevator 6 is located on the upper side of the loading box 72. The right conveying area 61 and the left conveying area 62 correspond to the first loading area 77 and the second loading area 78 respectively. Two groups of radar level devices 791 are fixedly installed on the partition 73, which are used to monitor the material level height in the first loading area 77 and the second loading area 78 respectively. A discharge port 792 is provided at the bottom of the loading box 72.

[0052] In the present invention, when the vibrating conveyor 5 screens the pecans, it is not possible to accurately detect the screening amount of the pecans in the upper area 514 and the middle area 515, but the pecans are respectively transported into the first loading area 77 and the second loading area 78 of the loading box 72 through the right conveying area 61 and the left conveying area 62 of the third elevator 6. During the initial transportation, the first loading area 77 and the second loading area 78 are isolated by the telescopic plate 74 and are not connected to the third loading area 79. As the screening and transportation continue, the pecans with a large screening amount will quickly fill up the first loading area 77. Or the second loading area 78, when the radar level sensor 791 detects that the pecans in the corresponding area are piled up to a set height, the output shaft of the second cylinder 75 corresponding to the area pushes the connecting rod 76 down, thereby driving the corresponding telescopic plate 74 to rotate, so that the area is connected with the third loading area 79, thereby increasing the loading amount of pecans of corresponding quality. When any radar level sensor 791 detects that the loading amount of the first loading area 77 or the second loading area 78 reaches the set height again, the loading operation of the loading box 72 is stopped to achieve one loading.

[0053] After the loading of the loading box 72 is completed, the output end of the monorail trolley 71 drives the loading box 72 to move to the top of a drying box 8, and the discharge port 792 at the bottom of the loading box 72 is opened. The pecans with a larger load are first unloaded and transported into the drying box 8. After the pecans of the same quality are unloaded, the monorail trolley 71 drives the loading box 72 to move to the top of the next drying box 8, and the output shaft of the second cylinder 75 pushes another connecting rod 76 down to rotate the telescopic plate 74 in this area, and the pecans enter the third loading area 79 and enter the drying box 8 from the discharge port 792, realizing the loading and unloading of pecans. It should be noted that the second cylinder 75 pushes the connecting rod 76 to control the rotation of the telescopic plate 74, which can also be used for blocking vibration when unloading pecans, thereby reducing the risk of blocking when unloading pecans.

[0054] The fourth elevator 9 is located below the discharge ports of the drying boxes 8. The discharge end of the fourth elevator 9 is located above the feed end of the vibrating feeder 10. The vibrating feeder 10 is provided with a plurality of diverter plates. The pecans falling onto the vibrating feeder 10 are fed one by one in multiple rows through the diverter plates. The discharge end of the vibrating feeder 10 is connected to the feed end of the X-ray sorter 11. The X-ray sorter 11 detects the fullness of the transported pecans, thereby further screening the pecans.

[0055] Working principle: The first elevator 1 transports the pecans into the cleaning machine 2 for cleaning to remove impurities attached to the surface of the pecans. The cleaned pecans are transported obliquely upward by the second elevator 3 and separated from the cleaning liquid. The blowing device 4 blows out hot air to preliminarily dry the transported pecans to remove moisture on the surface. The preliminarily dried pecans enter the upper area 514 of the vibrating conveyor 5.

[0056] As the double-layer vibrating screen 51 continues to vibrate, ordinary and unqualified pecans with a volume smaller than the mesh size of the first sieve plate 512 fall into the middle layer area 515. After being screened by the second sieve plate 513, unqualified pecans with a volume smaller than the mesh size of the second sieve plate 513 enter the lower layer area 516. The high-quality pecans on the upper layer and the ordinary pecans on the middle layer are respectively transported to the right conveying area 61 and the left conveying area 62 of the third elevator 6 for synchronous transportation.

[0057] The first loading area 77 and the second loading area 78 of the loading box 72 store the pecans transported by the right conveying area 61 and the left conveying area 62 respectively. The two sets of radar level sensors 791 continuously monitor the material level heights loaded in the first loading area 77 and the second loading area 78. When the material level height of one of the first loading area 77 or the second loading area 78 reaches the set height, the corresponding telescopic plate 74 is controlled to open. If the first loading area 77 reaches the material level height first, at this time, the output shaft of the second cylinder 75 corresponding to the first loading area 77 pushes the connecting rod 76 down, thereby driving the telescopic plate 74 in the first loading area 77 to rotate, so that the first loading area 77 is connected to the third loading area 79, thereby increasing the loading amount of pecans of the same quality in the first loading area 77. When any radar level sensor 791 detects that the loading amount of the first loading area 77 or the second loading area 78 reaches the set height again, the loading operation of the loading box 72 is stopped to achieve one-time loading.

[0058] After the loading of the loading box 72 is completed, the output end of the monorail trolley 71 drives the loading box 72 to move above a drying box 8, and the discharge port 792 at the bottom of the loading box 72 is opened. The pecans in the first loading area 77 and the third loading area 79 are first unloaded and transported into the drying box 8. After the pecans of the same quality are unloaded, the monorail trolley 71 drives the loading box 72 to move above the next drying box 8, and the output shaft of the second cylinder 75 corresponding to the second loading area 78 pushes the connecting rod 76 down, so that the telescopic plate 74 of the second loading area 78 rotates, and the second loading area 78 is connected to the third loading area 79, and the pecans enter the third loading area 79 and enter the drying box 8 from the discharge port 792, so as to realize the loading and unloading of pecans, and the monorail trolley 71 drives the loading box 72 to reset and continue to load pecans.

[0059] A plurality of drying boxes 8 dry the pecans. The dried pecans fall from the discharge port of the drying boxes 8 onto the fourth elevator 9 and are transported to the vibrating feeder 10. The vibrating feeder 10 continuously vibrates and cooperates with a plurality of diverter plates to divert the accumulated pecans, thereby transporting the pecans in multiple rows to the X-ray sorter 11 one by one. The X-ray sorter 11 detects the fullness of the transported pecans, and further screens the pecans according to their fullness, thereby completing the processing of fresh pecans.

[0060] When the sieve holes of the double-layer vibrating screen 51 are cleaned, the output shaft of the first cylinder 573 drives the connecting frame 574 and the driving roller 58 to move upward. When the connecting frame 574 moves upward, it drives the lifting frame 59 to slide upward synchronously, so that the rack 591 and the second gear 582 are stably meshed. When the driving roller 58 moves upward in the slot hole 54, it pushes the sealing plate 55 upward and compresses the elastic member 56. At this time, the through hole 53 is opened, and the output end of the electric slide 571 drives the fixed plate 572, the connecting frame 574 and the driving roller 58 to move. When the driving roller 58 moves in the through hole 53, the second gear 582, the first gear 583 and the rack 591 are meshed and transmitted, so that the driving roller 58 can rotate freely. When the driving roller 58 rotates, the flexible belt 581 unfolds and slaps the bottom of the first sieve plate 512 and the second sieve plate 513, so that the pecans stuck in the sieve holes are pushed out, and the pecans in the sieve holes are cleaned. In order to prevent the pecans from flying out from the top of the double-layer vibrating screen 51, the top of the double-layer vibrating screen 51 can be blocked during cleaning.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
