Description

Technical Field

[0001] The present invention relates to the field of agricultural sowing, and in particular to a directional loading system and a loading method for peanut seeds. Background Art

[0002] Peanuts are an important economic crop and oil crop. The development of peanut production has become one of the important ways to increase agricultural efficiency and farmers' income. There are many ways to sow peanuts, including row sowing and hole sowing. Hole sowing is a method of digging holes in the field according to a certain row and hole spacing for sowing. Hole sowing is relatively labor-intensive and suitable for planting in small areas or special plots.

[0003] Drill seeding is a common method for peanut cultivation. This involves sowing peanut seeds (hereinafter referred to as seeds) into the soil using a seeder or manual trenching at a specific row and plant spacing. The seeds are then covered with soil, typically with two or three seeds placed in the same location. After the seeds have emerged, the strongest seedlings are selected and retained. This method facilitates field management and mechanized operations, as well as root development and pod formation. However, this method presents the following issues:

[0004] Problem 1: The spacing between seeds is difficult to precisely control, resulting in uneven growth and affecting peanut yield;

[0005] Question 2: The directions of seed embryo heads vary. The germination rate of peanuts mainly depends on the position of the peanut embryo in the soil. If the head of the peanut embryo is facing downward, its germination rate will be greatly improved, while if the head of the peanut embryo is facing upward, its germination rate will be lower.

[0006] Based on this, a device that can assist in planting and control the spacing between peanut seeds and the direction of the embryo heads is needed. To address the above problems, we have designed a device for an automatic positioning and loading system for peanut seeds, as shown in patent CN202411097202.2. In this solution, the feeding part is used to automatically and orderly transfer the peanut seeds to the main conveying mechanism, while the blocking mechanism in the feeding part is used to preliminarily control the spacing between each seed, and the visual judgment part and the rejection part are used to judge and reject unqualified peanut seeds, thereby ensuring the quality of each seed. The seeds on the main conveying mechanism are transferred by the diversion part arranged on one side of the main conveying mechanism. The seeds are diverted to the diversion conveying mechanism, and the interval between each seed is precisely controlled by multiple groups of spaced-apart diversion conveying mechanisms to ensure uniform growth of peanuts. The unloading part is used to transfer the seeds in the diversion conveying mechanism to the positioning loading part, and then the position adjustment mechanism in the unloading part is used to adjust the position of the seed embryo head to keep it in the same direction. Finally, the hot press in the positioning loading part is used to package the seeds diverted and transmitted by multiple groups of diversion conveying mechanisms together in the same direction using water-soluble film. When sowing, the whole row can be directly planted, which ensures the interval between seeds and the same direction of the embryo heads, thereby improving the germination rate and the planting speed.

[0007] The technical solution of this patent can realize seed spacing control and adjustment of the same orientation of the embryo head, but the structure is relatively complex and the cost is high. At the same time, this case adopts a material blocking mechanism and a cylinder to push the material, but due to the unstable position of the peanuts, the peanuts are often stuck in the material blocking mechanism, that is, the material jamming phenomenon, causing the actual spacing to fall short of the ideal expectation, or the position or direction changes during the cylinder pushing process, causing the peanuts to be stuck at the interface, thereby failing to directly proceed to the subsequent process, which is inconvenient to use.

[0008] At the same time, this solution uses ordinary conveyor belts for transportation. However, due to friction or other external force factors, ordinary conveyor belts can easily cause the peanuts to change in direction later due to other factors even if they are initially positioned, resulting in deviations in the entire subsequent process and packaging.

[0009] Therefore, the present invention is based on the applicant's existing patent (patent number: CN202411097202.2, title: Automatic positioning and loading system and loading method for peanut seeds), and improves the technical problems of "easy material jamming", "easy seed position deviation" and "high cost" during use.

DETAILED DESCRIPTION

[0050] The following is a combination of the embodiments of the present invention Figure 1-16 , the technical solutions in the embodiments of the present invention are described in detail.

[0051] Example

[0052] like Figure 1 As shown, a directional loading system for peanut seeds includes a control unit 1, a loading unit 2, a round belt conveyor line 3, a visual judgment unit 4, a bidirectional material removal device 5, a discharge unit 6, an interval conveyor line 7, a sealing loading unit 8 and a sealing film assembly 9.

[0053] The main function of the control unit 1 is to control the entire system. Through the control unit 1, the operation and parameter adjustment of each part of the system can be controlled separately. The control unit 1 is an existing device and can be used directly.

[0054] The main function of the loading part 2 is to automatically load the seeds in an orderly manner. At the same time, the loading part 2 can also arrange the seeds horizontally to facilitate subsequent visual identification and packaging.

[0055] The main function of the round belt conveyor line 3 is to transport seeds after horizontal arrangement. The front end of the round belt conveyor line 3 is connected to the loading part 2. The round belt conveyor line 3 ensures the stability of the seeds during transportation and prevents the seeds from being displaced during transportation. At the same time, the round belt conveyor line 3 also serves as a carrier for the installation of the visual judgment part 4 and the two-way picking device 5.

[0056] The main function of the visual judgment unit 4 is to take photos and identify seeds passing under the visual judgment unit 4, so as to facilitate the detection and judgment of defective seeds and confirm the orientation of the seed embryo.

[0057] The main function of the bidirectional rejecting device 5 is to reject defective seeds and seeds with incorrect embryo head orientation according to the judgment result of the visual judgment part 4.

[0058] The main function of the unloading part 6 is to move the seeds transported to the end of the round belt conveyor line 3 to the interval conveyor line 7, and use the interval conveyor line 7 to fix the orientation and position of the seeds, so as to facilitate the use of the heat sealing mechanism 82 in the sealing loading part 8 to package the seeds with determined orientation and interval.

[0059] The main function of the sealing film assembly 9 is to provide a water-soluble heat-sealing film, which is used to encapsulate seeds. The water-soluble heat-sealing film is an existing film that can be heat-sealed at low temperature and is water-soluble and can be used directly.

[0060] like Figure 1 、 2 As shown in Figure 3, the loading part 2 includes a vibrating loading tray 21 and a loading tray mounting frame 22. The loading tray mounting frame 22 is placed on the ground. The vibrating loading tray 21 is connected to the loading tray mounting frame 22. The loading tray mounting frame 22 is a rectangular metal frame welded from square tubes. Its main function is to serve as a base for installing the vibrating loading tray 21.

[0061] The vibrating loading tray 21 is a spiral loading device that utilizes vibration loading. The technology and equipment for utilizing vibration loading can be directly used for existing devices. In order to facilitate the arrangement of seeds so that the seeds are arranged horizontally, a rectangular discharge plate 25 is integrally fixed on the discharge end 23 of the vibrating loading tray 21.

[0062] A rectangular metal sheet is fixed to the side of the discharge end 23 by screws, and this metal sheet is named a limiting partition 24. The limiting partition 24 separates the discharge end 23, and separates a smaller discharge channel with a "U"-shaped cross-section at the discharge end 23. The width of the channel is adjustable by adjusting the position of the limiting partition 24 on the discharge end 23. The discharge plate 25 is located on the lower surface of the discharge channel. When the seeds rise from the inside of the vibrating loading tray 21 and move to the discharge end 23, they are sorted horizontally on the discharge plate 25 under the restriction of the discharge channel.

[0063] In order to preliminarily adjust the spacing between seeds, this embodiment preferably uses the vibrating loading tray 21 as a multi-vibration source loading tray. The vibration frequency inside the vibrating loading tray 21 is different from the vibration frequency at the discharge end 23. By adjusting the vibration frequency, the spacing between adjacent seeds at the discharge end 23 is greater than the spacing between seeds inside the vibrating loading tray 21.

[0064] Definition: In this embodiment, the ground is used as the reference, the direction from the ground to the equipment is the upward direction, and the direction from the head end of the peanut seed embryo to the other end and the same as the conveying direction of the interval conveyor line 7 is the horizontal direction.

[0065] like Figure 1 、 4 As shown in Figures 5 and 6, the round belt conveyor line 3 includes a conveying frame 31, support legs 34, a conveying motor 32, a conveying wheel 35 and a conveying round belt 37. The conveying frame 31 is connected to the support legs 34, and the round belt conveyor line 3 is placed on the ground through the support legs 34. There are two conveying wheels 35, which are respectively arranged at both ends of the conveying frame 31. The two conveying wheels 35 are connected by a conveying round belt 37. The conveying motor 32 is arranged at one end of the conveying frame 31 and is connected to one of the conveying wheels 35. The conveying motor 32 can drive the conveying wheel 35 to move, and then drive the conveying round belt 37 to move, thereby completing the conveying of seeds.

[0066] The conveying rack 31 is a rectangular metal plate. There are two conveying racks 31, and the two conveying racks 31 are connected together in parallel through rectangular connecting blocks. The main function of the conveying rack 31 is to serve as a carrier for installing the conveying wheel 35. In order to facilitate the stable placement of the conveying rack 31, a support leg 34 is fixed at the lower end of the conveying rack 31 with screws, and the conveying rack 31 is placed on the ground through the support leg 34.

[0067] The conveying wheel 35 is a rubber wheel with a circular cross section. The conveying wheel 35 is fixed to both ends of the conveying frame 31 through bearings and a connecting shaft. The conveying wheel 35 can rotate freely along the connecting shaft.

[0068] In order to facilitate the installation of the conveyor belt 37, two circular grooves are concave on the arcuate surface of the conveyor wheel 35, and the conveyor belt 37 is placed in this groove. The two conveyor wheels 35 are connected by the conveyor belt 37. When one conveyor wheel 35 rotates, the other conveyor wheel 35 will also rotate under the action of the conveyor belt 37. In order to facilitate the rotation of the conveyor wheels 35, a conveying motor 32 is fixed to the conveyor frame 31 with screws. The conveying motor 32 is connected to the conveyor wheel 35 at one end of the conveyor frame 31. The connection method can be an existing commonly used connection method, such as a gear connection. The conveyor belt 37 is driven by the conveyor motor 32 to move, thereby realizing the transportation of seeds.

[0069] The conveyor belt 37 is a conveyor belt with a circular cross-section. In order to ensure the stability of operation, the conveyor belt 37 is preferably supported by rubber material. Two groups of conveyor belts 37 are arranged on the conveying wheel 35. The two groups of conveyor belts 37 are distributed in parallel on the conveying wheel 35 and have a certain interval. In this embodiment, the preferred interval is 3 mm. Since both conveyor belts 37 are circular and there is a certain interval between the two conveyor belts 37, a V-shaped space is formed between the two conveyor belts 37. This space is named V-shaped placement groove 39, and seeds are placed in the V-shaped placement groove 39.

[0070] In order to facilitate the stable placement of seeds from the loading part 2 to the round belt conveyor line 3, a receiving tray 33 is fixed at the front end of the round belt conveyor line 3 by screws. The receiving tray 33 is rectangular as a whole and is fixed on the conveyor frame 31. The receiving tray 33 is located above the conveyor round belt 37. A through hole is opened on the lower surface of the receiving tray 33. The seeds can fall from the through hole into the conveyor round belt 37 below. In order to facilitate the receiving of materials, the four surfaces of the receiving tray 33 are inclined. These four surfaces are named The inclined surface is a baffle 310, which can guide the seeds falling into the receiving tray 33 to facilitate the seeds falling onto the conveyor belt 37 below. In order to facilitate material receiving and feeding, a receiving port 36 and a discharge port 38 are respectively provided on the two baffles 310 on the receiving tray 33 that are perpendicular to the conveyor belt 37. The seeds fall into the receiving tray 33 from the receiving port 36, fall onto the conveyor belt 37 after being guided by the baffle 310, and are then transported out from the discharge port 38 for transportation.

[0071] Definition: During the seed transportation process of the round belt conveyor line 3, the seeds are transported from one end where the receiving tray 33 is set to the other end, where the one end where the receiving tray 33 is set is the front end and the other end is the tail end.

[0072] like Figure 1 and 7As shown, the visual judgment unit 4 includes a detection camera 41 and a camera mounting bracket 42. The camera mounting bracket 42 is an inverted "U"-shaped metal frame made of sheet metal. Its main function is to install the detection camera 41. The camera mounting bracket 42 is fixed to the conveyor frame 31 near the middle with screws. The detection camera 41 is fixed to the camera mounting bracket 42 with screws. The detection camera 41 is located above the conveyor belt 37. The seeds passing on the conveyor belt 37 are photographed by the detection camera 41 and judged and identified by the control unit 1.

[0073] Regarding the principle of visual judgment of the head and tail of peanut seeds by the detection camera 41, this embodiment adopts the YOLOV8 classification model. YOLOV8 is a deep learning model based on target detection and is the latest version of the YOLO (You Only Look Once) series of models. YOLOV8 uses an end-to-end training method based on a convolutional neural network (CNN) and can simultaneously detect multiple targets in an image. After the peanut seeds reach a fixed position, the detection camera 41 takes a photo and visually inspects the half of the peanuts that have escaped. After the inspection is completed, a comparison is made and an exact value is returned to the peanut belt, thereby determining the direction of the peanuts' forward movement on the round belt conveyor line 3. In addition, the direction of the embryo head needs to be set in the control unit 1. For example, the forward direction of the embryo head can be set as a preset direction. During the visual inspection process, seeds with embryo heads facing backward are defined as seeds with incorrect orientation. At the same time, during the peanut visual judgment process, seeds with unclear or damaged heads or tails are defined as defective products, providing a basis for subsequent mechanical operations.

[0074] Regarding the control of the detection camera 41 to take pictures of seeds, an infrared sensor is set on the conveying rack 31. When the infrared sensor detects that seeds are passing by, it triggers the detection camera 41 to take pictures. This is an existing mature technology and will not be elaborated here.

[0075] like Figure 1 and 7 As shown, the bidirectional rejecting device 5 includes a cross slot 51 and a rejecting nozzle 52. The rejecting nozzle 52 is installed on the cross slot 51 through a serpentine tube 56. The rejecting nozzle 52 is used to reject seeds with incorrect directions and defective varieties respectively.

[0076] The cross groove 51 is a cross-shaped slide groove formed by bending a metal plate. The four ports of the cross groove 51 are named as the serpentine tube installation port and the material removal port respectively. Each serpentine tube installation port and each material removal port are distributed on the same side. At the intersection in the middle of the cross groove 51, a rectangular groove is opened perpendicular to the surface of the cross groove 51. This groove is named the round belt give way groove 53. After the cross groove 51 is fixed to the conveyor frame 31 with screws, the conveyor round belt 37 is placed on the round belt give way groove 53, that is, the cross groove 51 is located below the conveyor round belt 37, and the conveyor round belt 37 passes over the cross groove 51.

[0077] In order to facilitate the material removal, a material removal nozzle 52 is installed on each of the two material removal ports through a serpentine tube 56. The serpentine tube 56 is connected to the air pump. The position of the material removal nozzle 52 can be adjusted through the serpentine tube 56 so that the two material removal nozzles 52 correspond to the conveyor belt 37 and the material removal port.

[0078] There are two reject ports, namely the first reject port 54 and the second reject port 55. One reject nozzle 52 corresponds to the first reject port 54, and the other reject nozzle 52 corresponds to the second reject port 55. The reject nozzle 52 and the compressed air in the air pump can be used to blow defective products off the conveyor belt 37 and discharged from the first reject port 54. The other reject nozzle 52 can be used to blow seeds with the wrong direction off the conveyor belt 37 and discharged from the second reject port 55, and the seeds rejected by the second reject port 55 can be placed again in the loading part 2 for use.

[0079] Regarding the switch control of the material removal nozzle 52: the switch of the material removal nozzle 52 is controlled by the control unit 1. The control unit 1 controls the switch of different material removal nozzles 52 according to the judgment result of the visual judgment unit 4, which is easy to use.

[0080] like Figure 14 and 15 As shown, in order to facilitate the repeated placement of seeds removed from the second removal port 55 into the loading part 2 for use, this embodiment preferably places a return mechanism 10 near the second removal port 55 in the round belt conveyor line 3. The return mechanism 10 is placed on the ground, and the upper end of the return mechanism 10 is located above the vibrating loading tray 21. The seeds removed from the second removal port 55 can be transported back to the vibrating loading tray 21 through the return mechanism 10, so that the seeds can continue to flow back for use in the wrong direction.

[0081] The return material mechanism 10 includes a Z-shaped return material rack 101, a collecting tray 102 and a feeding belt 104. The collecting tray 102 and the feeding belt 104 are installed on the return material rack 101, and the collecting tray 102 is located at the lower end of the return material rack 101. The peanut seeds with the wrong direction removed from the second removal port 55 fall into the collecting tray 102 and are transported to the upper end of the return material rack 101 via the feeding belt 104, and then fall into the vibrating loading tray 21.

[0082] The collecting tray 102 is made of four metal plates welded in pairs. The collecting tray 102 is fixed to the lower end of the return rack 101 by screws. The collecting tray 102 spans above the feeding belt 104, and the lower end of the collecting tray 102 is open. The peanuts falling from the second picking port 55 fall into the collecting tray 102 and are transported back to the vibrating loading tray 21 through the feeding belt 104 of the collecting tray 102. When the feeding belt 104 moves, in order to avoid position interference between the feeding belt 104 and the collecting tray 102, a gap is made on the contact point between the collecting tray 102 and the feeding belt 104.

[0083] The return material rack 101 is a Z-shaped metal rack. There are two return material racks 101. The two return material racks 101 are connected to each other by a connecting rod to ensure the stability of the return material rack 101. A conveyor roller is installed at each end of the return material rack 101. The conveyor roller is a circular transmission roller. The two ends of the conveyor roller are installed on the return material rack 101 through bearings. The feeding belt 104 is sleeved on the outside of the conveyor roller. In order to facilitate the driving of the conveyor roller, a motor is fixed to the lower end of the return material rack 101 with screws. This motor is named return material motor 105. The return material motor 105 is connected to the conveyor roller at the lower end of the return material rack 101 through a gear. The return material motor 105 can drive the conveyor roller to rotate, thereby driving the feeding belt 104 to move.

[0084] The feeding belt 104 is a conveyor belt made of rubber, which is an existing product. In order to facilitate the transportation of peanut seeds, a rectangular plate is protruded from the surface of the feeding belt 104 perpendicular to the feeding belt 104. This plate is named a lifting plate 106. When the feeding belt 104 moves, the seeds that fall into the collecting tray 102 can be transported back to the vibrating loading tray 21 through the lifting plate 106, avoiding the manual transportation of the seeds blown off at the second ejection port 55 back to the vibrating loading tray 21.

[0085] like Figure 1 and 8 As shown, the unloading part 6 includes a unloading part mounting frame 61, a first drive motor 62, a first linear slide pair 63 and a pneumatic clamp 65. The unloading part mounting frame 61 is arranged on the mounting frame 81 in the sealing loading part 8, the first linear slide pair 63 is arranged on the unloading part mounting frame 61, and the pneumatic clamp 65 is connected to the first linear slide pair 63. The pneumatic clamp 65 can be driven by the first drive motor 62 to move along the first linear slide pair 63. The pneumatic clamp 65 can be used to move the seeds transported to the end of the round belt conveyor line 3 to the interval conveyor line 7.

[0086] The main function of the blanking part mounting frame 61 is to install the various components in the blanking part 6. The blanking part mounting frame 61 is made of metal sheet metal as a whole. The first linear slide pair 63 is installed on the blanking part mounting frame 61 with screws. The first drive motor 62 is installed on the blanking part mounting frame 61 with screws and is located at one end of the first linear slide pair 63.

[0087] In order to facilitate the control of the movement of the pneumatic clamp 65 by the first drive motor 62, a pulley is fixed at the other end of the blanking mounting frame 61, and this pulley is named the first pulley 64. At the same time, a first pulley 64 is also fixed on the output shaft of the first drive motor 62. A belt 67 is mounted on the two first pulleys 64, and the first drive motor 62 can drive the belt 67 to move.

[0088] In order to facilitate the adjustment of the height of the pneumatic clamp 65, a lifting push rod 66 is fixed to the slider in the first linear slide pair 63 by screws, and the pneumatic clamp 65 is connected to the lifting push rod 66 by screws. The height of the pneumatic clamp 65 can be adjusted by the lifting push rod 66. In addition, a fixed pressure plate is provided on the lifting push rod 66 by screws, and the fixed pressure plate is connected to the belt 67 by screws. The belt 67 drives the lifting push rod 66 to move along the first linear slide pair 63.

[0089] The pneumatic clamp 65 is an existing pneumatically driven clamp, which can be used directly with existing devices. In order to prevent the pneumatic clamp 65 from damaging the seeds, sponge protective covers are provided on both clamps of the pneumatic clamp 65 to protect the seeds.

[0090] When the seeds are transported to the end of the round belt conveyor line 3, in order to facilitate the unloading part 6 to unload the seeds in time, a second camera 68 is fixed to the unloading part mounting frame 61 at one end of the unloading part 6 close to the round belt conveyor line 3 with screws. The second camera 68 is connected to the second control box 12 in the control part 1. The transported seeds can be positioned by the second camera 68, which facilitates the pneumatic clamp 65 to clamp and unload the seeds. In addition, the method of positioning by taking pictures with a camera is an existing technology and can be used directly.

[0091] Regarding the movement of the pneumatic clamp 65: When the seeds are identified as qualified seeds by the visual judgment part 4, the pneumatic clamp 65 in the unloading part 6 moves to the end of the unloading part 6 close to the round belt conveyor line 3. When the seeds are delivered, the pneumatic clamp 65 clamps the seeds with the assistance of the second camera 68.

[0092] like Figure 1 、 9As shown in Figure 10, the interval conveying line 7 includes a second drive motor 71 and an interval conveying belt 75. The second drive motor 71 is installed on the mounting plate 83 in the sealed loading part 8. The interval conveying belt 75 is connected to the second drive motor 71. The second drive motor 71 can drive the interval conveying belt 75 to move, and then transport the seeds to the heat sealing mechanism 82 in the sealed loading part 8 for packaging.

[0093] In order to facilitate the installation of the interval conveyor belt 75, a second pulley 73 is fixed on the mounting plate 83 using a pulley mounting frame 74. The pulley mounting frame 74 is a "U"-shaped metal frame made of sheet metal. The pulley mounting frame 74 is fixed to the mounting plate 83 using screws. The second pulley 73 is pinned to the pulley mounting frame 74, and the second pulley 73 can rotate freely along the pin connection.

[0094] A second pulley 73 is also fixed on the output shaft of the second driving motor 71 , and both ends of the interval conveying belt 75 are respectively sleeved on the two second pulleys 73 to realize transmission.

[0095] The interval conveying belt 75 is a circular transmission belt. The inner side of the interval conveying belt 75 is provided with teeth. The interval conveying belt 75 is meshed with the second pulley 73 through the teeth. In order to facilitate the equal-interval conveying of seeds and limit the position of the seeds during the seed conveying process to prevent the seed position from deviating, a plurality of interval blocks 76 are fixed at intervals on the outer surface of the interval conveying belt 75. The interval blocks 76 are rectangular blocks. The interval blocks 76 are integrally connected to the interval conveying belt 75. A plurality of interval blocks 76 are evenly distributed on the interval conveying belt 75. A placement cavity for placing seeds is formed between two adjacent interval blocks 76. The pneumatic clamp 65 places the seeds in the placement cavity and transports them to the heat sealing mechanism 82 in the sealing loading part 8 through the second drive motor 71.

[0096] When the seeds are transported to the heat sealing mechanism 82, in order to facilitate unloading, a unloading assembly 72 is also provided on the mounting plate 83. The main function of the unloading assembly 72 is to unload the seeds on the interval conveying line 7 to the heat sealing mechanism 82. The unloading can be carried out using the same structure as the unloading part 6 or by using the unloading assembly 72. The unloading can be carried out according to the usage. The unloading assembly 72 is used for unloading in the attached drawings of this embodiment.

[0097] The unloading assembly 72 includes a unloading rod 77 and a unloading piece 78 fixed to the end of the unloading rod 77. The unloading rod 77 is a pneumatic push rod. The unloading rod 77 is fixed to the mounting plate 83 through an "L"-shaped metal plate. The unloading piece 78 is a circular piece supported by rubber. The unloading piece 78 is connected to the end of the unloading rod 77. The seeds transported to the end of the interval conveying line 7 can be pushed down through the unloading piece 78 and the unloading rod 77 to complete the unloading.

[0098] like Figure 1 、11 As shown in , 12 and 13, the sealing loading part 8 includes a mounting frame 81, a mounting plate 83, a second linear slide pair 84, a limiting gas rod 85 and a heat sealing mechanism 82. The mounting plate 83 is fixed on the mounting frame 81, the second linear slide pair 84 is arranged on the mounting plate 83, and the limiting gas rod 85 and the heat sealing mechanism 82 are connected to the second linear slide pair 84.

[0099] The mounting frame 81 is a metal frame formed by splicing 30*30 aluminum profiles. Its main function is to serve as a carrier for installing various components in the sealing loading part 8. The mounting frame 81 is placed on the ground.

[0100] The mounting plate 83 is a rectangular metal plate with a certain thickness. The mounting plate 83 is fixed in the mounting frame 81 by screws. Two sets of second linear guide rail pairs 84 are fixed on the mounting plate 83 by screws. The two sets of second linear guide rail pairs 84 are distributed in parallel on the mounting plate 83.

[0101] The main function of the second linear slide pair 84 is to facilitate the heat sealing mechanism 82 to move along the second linear slide pair 84, to facilitate the placement of seeds between the two layers of water-soluble sealing film, and to facilitate the heat sealing mechanism 82 to encapsulate the seeds.

[0102] The heat sealing mechanism 82 includes a base plate 87 , a fixed plate 88 , a movable plate 811 , a heat sealing block 89 , a screw motor 812 and a guide rod 813 .

[0103] The base plate 87 is a rectangular plate made of metal. The base plate 87 is connected to the sliders on the two sets of second linear slide rail pairs 84 by screws. Two circular guide rods 813 are fixed to the upper surface of the base plate 87 by screws. A rectangular fixing plate 88 is fixed to the upper ends of the two guide rods 813 by screws, and a lead screw motor 812 is fixed to the fixing plate 88 by screws.

[0104] The movable plate 811 is a rectangular metal plate. Two linear bearings with flanges are fixed at both ends of the movable plate 811 by screws. The linear bearings can cooperate with the guide rod 813 so that the movable plate 811 can move up and down along the guide rod 813. In order to facilitate the control of the up and down movement of the movable plate 811, a flange nut is fixed on the movable plate 811 by screws. The flange nut cooperates with the screw on the screw motor 812. Under the action of the screw motor 812, the movable plate 811 can move up and down along the guide rod 813 in a controllable manner.

[0105] The heat sealing block 89 is a rectangular metal block. The main function of the heat sealing block 89 is to heat seal the seeds. In order to facilitate heat sealing, the heat sealing block 89 is connected to the lower surface of the movable plate 811 by screws. Two circular mounting holes are opened on the surface of the heat sealing block 89, and two circular heating rods are inserted in the mounting holes. The heat sealing block 89 can be heated by the heating rods, which facilitates the heat sealing of seeds.

[0106] In order to make room for the seeds and facilitate the packaging of the seeds by the heat sealing block 89, a rectangular groove is provided on the lower surface of the heat sealing block 89, and this groove is named the making room groove 810. When the heat sealing block 89 is pressed down to heat-seal the seeds, the seeds are in the making room groove 810 to prevent the heat sealing block 89 from squeezing the seeds and causing damage to the seeds.

[0107] There are two layers of water-soluble sealing films on the upper surface of the substrate 87. In order to facilitate the movement of the seeds to be encapsulated between the two layers of water-soluble sealing films, a limiting gas rod 85 is fixed on the substrate 87 by screws. The limiting gas rod 85 is a retractable push rod driven by air pressure. A U-shaped limiting card 86 is fixed at the end of the limiting gas rod 85 by screws. The unloading component 72 pushes the seeds from the interval conveying line 7 into the U-shaped limiting card 86. The U-shaped limiting card 86 limits the direction of the seeds, and after the limiting gas rod 85 moves between the two layers of water-soluble sealing films on the second linear slide rail pair 84 as the substrate 87 moves, the limiting gas rod 85 contracts, leaving the seeds between the water-soluble sealing films, making it convenient for the heat sealing block 89 to perform heat sealing.

[0108] In order to facilitate the control of the movement of the substrate 87 along the second linear slide pair 84, a telescopic push rod (the telescopic push rod is not shown in the figure) is fixed on the substrate 87 by screws. The telescopic push rod can drive the substrate 87 to move linearly along the second linear slide pair 84, and then move the seeds between the two layers of water-soluble sealing film, making it convenient for the heat sealing block 89 to encapsulate the seeds.

[0109] like Figure 1 、 12 As shown in Figure 13, the sealing film assembly 9 includes a first water-soluble sealing film 91 and a second water-soluble sealing film 92. The first water-soluble sealing film 91 and the second water-soluble sealing film 92 are existing water-soluble sealing films. The first water-soluble sealing film 91 and the second water-soluble sealing film 92 are both in a round roll shape, and their main function is to encapsulate peanut seeds.

[0110] In order to facilitate the fixing of the first water-soluble sealing film 91 and the second water-soluble sealing film 92 on the mounting frame 81, two sealing film mounting frames 93 are fixed on the mounting frame 81 by screws. The sealing film mounting frame 93 is a frame composed of a metal plate and a mounting shaft. The first water-soluble sealing film 91 and the second water-soluble sealing film 92 are placed on the sealing film mounting frame 93.

[0111] Regarding the installation positions of the first water-soluble sealing film 91 and the second water-soluble sealing film 92 on the mounting frame 81 , the first water-soluble sealing film 91 and the second water-soluble sealing film 92 are installed on the same side of the mounting frame 81 , wherein the second water-soluble sealing film 92 is located above the mounting frame 81 .

[0112] Regarding the positional relationship between the first water-soluble sealing film 91 and the second water-soluble sealing film 92 on the heat sealing mechanism 82, and the direction setting of the first water-soluble sealing film 91 and the second water-soluble sealing film 92, a sealing film guide rod 94 is fixed to the mounting frame 81 by screws, and the first water-soluble sealing film 91 and the second water-soluble sealing film 92 adjust the direction of the film through the sealing film guide rod 94, wherein the second water-soluble sealing film 92 is flatly laid above the substrate 87, and the first water-soluble sealing film 91 is located above the second water-soluble sealing film 92 with a gap between the two, and the first water-soluble sealing film 91 and the second water-soluble sealing film 92 both pass through the heat sealing mechanism 82 and are located below the heat sealing block 89.

[0113] When the peanut seeds are placed between the first water-soluble sealing film 91 and the second water-soluble sealing film 92, in order to prevent the peanut seeds from shifting in position, a limit strip is fixed on the mounting frame 81 by screws, and a rectangular limit piece 95 is fixed at the end of the limit strip by glue. The limit piece 95 is made of rubber, and there is a 3mm gap between the lower end of the limit piece 95 and the substrate 87. The limit piece 95 contacts the upper end of the first water-soluble sealing film 91 and presses the first water-soluble sealing film 91 at a distance of 3mm from the upper surface of the substrate 87, thereby preventing the seeds located between the first water-soluble sealing film 91 and the second water-soluble sealing film 92 from moving.

[0114] Regarding the seed packaging process: before packaging, the unloading assembly 72 unloads the seeds from the interval conveyor belt 75 to the base plate 87. At this time, the limiting gas rod 85 extends, and the unloaded seeds are now located in the U-shaped limiting card 86. The U-shaped limiting card 86 limits the position of the seeds to prevent the seeds from moving. Then the telescopic push rod drives the base plate 87 to move along the second linear slide pair 84 (the displacement distance is the distance between the two seeds after packaging). At this time, the first water-soluble sealing film 91 and the second water-soluble sealing film 92 remain in position, and the U-shaped limiting card 86 drives the seeds to move synchronously. After reaching the specified distance, the limiting gas rod 85 contracts, releasing the U-shaped limiting card 86 from limiting the seeds. Then the telescopic push rod drives the base plate 87 to move in the opposite direction along the second linear slide pair 84 to reset (in this process, the peanut seeds are between the first water-soluble sealing film 91 and the second water-soluble sealing film 92, and the position remains unchanged under the action of the limiting piece 95). After resetting, the seeds are below the heat sealing block 89, and then the screw motor 812 drives the heat sealing block 89 to move downward to complete the seed packaging.

[0115] This embodiment is about the control of the loading system: the loading system is controlled by the control unit 1, the control unit 1 includes a first control box 11 and a second control box 12, wherein the first control box 11 is installed on the round belt conveyor line 3, and the round belt conveyor line 3 and the visual judgment unit 4 and the bidirectional picking device 5 arranged on the round belt conveyor line 3 are controlled by the first control box 11, and the second control box 12 is installed on the sealing loading unit 8, and the unloading unit 6, the interval conveyor line 7 and the sealing loading unit 8 are controlled by the second control box 12.

[0116] like Figure 14 and 16 As shown, after the heat sealing mechanism 82 and the water-soluble sealing film have packaged the seeds, in order to facilitate the shrinking of the packaged water-soluble film with the seeds, a film rolling mechanism 96 is installed on the other side of the mounting frame 81 away from the first water-soluble sealing film 91. The film rolling mechanism 96 can shrink the packaged water-soluble sealing film.

[0117] The film rolling mechanism 96 includes a film rolling motor 97, a film rolling motor mounting frame 98 and a film rolling rod 99. The film rolling motor mounting frame 98 is a rectangular plate made of metal. There are two film rolling motor mounting frames 98, and the two film rolling motor mounting frames 98 are connected by a connecting rod. A round rod is installed at the upper end of the film rolling motor mounting frame 98 using a bearing, and this round rod is named film rolling rod 99. A film rolling disk is sleeved on the film rolling rod 99, and one end of the water-soluble sealing film at the rear end of the package is wound around this film rolling disk. A motor is fixed on the film rolling motor mounting frame 98 using screws, and this motor is named film rolling motor 97. The film rolling motor 97 is connected to the film rolling rod 99 through gears. The film rolling motor 97 can drive the film rolling rod 99 and the film rolling disk to rotate, thereby realizing the contraction of the water-soluble sealing film after packaging. At the same time, the film rolling motor 97 can also drive the disc-shaped first water-soluble sealing film 91 and the second water-soluble sealing film 92 to unfold, which is convenient for seed packaging.

[0119] S1: Screening peanuts of appropriate size and placing them into the vibrating loading tray 21;

[0120] S2: The vibrating feeding tray 21 vibrates and feeds the peanuts in the feeding tray to the discharge end 23, and adjusts them to be arranged in a horizontal spaced pattern on the discharge plate 25, and then feeds them to the round belt conveyor line 3;

[0121] S3: The visual judgment unit 4 detects the orientation of the peanut head and determines whether the peanut is defective. If it is defective, the process proceeds to step S4. If it is in the wrong orientation, the process proceeds to step S5. If it is good and the orientation is correct, the process proceeds to step S6.

[0122] S4: The rejecting nozzle 52 in the bidirectional rejecting device 5 rejects defective peanuts from the round belt conveyor line 3 through the first rejecting port 54 on the cross slot 51;

[0123] S5: The rejecting nozzle 52 of the bidirectional rejecting device 5 rejects the peanuts with the wrong embryo head direction from the round belt conveyor line 3 through the second rejecting port 55 on the cross slot 51 and collects and returns them by the returning mechanism 10, and then goes to step S1;

[0124] S6: The unloading section 6 transfers the peanuts delivered to the end of the round belt conveyor line 3 to the interval conveyor belt 75 in the interval conveyor line 7;

[0125] S7: The interval conveyor belt 75 in the interval conveyor line 7 transports peanut seeds at equal intervals;

[0126] S8: The unloading assembly 72 unloads the peanut seeds from the interval conveying belt 75 onto the heat sealing mechanism 82;

[0127] S9: The U-shaped limit card 86 moves the unloaded seeds to the bottom of the heat sealing mechanism 82 and is located between the two layers of water-soluble sealing films. The heat sealing block 89 moves downward to heat-seal the peanuts between the two layers of water-soluble sealing films.

[0128] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.

The discharge assembly (72) is arranged on the sealed loading part (8) near the end of the interval conveying belt (75). The discharge assembly (72) can be controlled to discharge the peanut seeds from the interval conveying belt (75).

8. A method for loading peanut seeds according to any one of claims 1 to 7, characterized in that The steps include: S1: screening peanuts of appropriate size and placing them into a vibrating loading tray (21); S2: The vibration loading tray (21) vibrates and loads the peanuts in the tray to the discharge end (23), and adjusts them to be arranged in a horizontal interval on the discharge plate (25), and then loads them onto the round belt conveyor line (3); S3: The visual judgment unit (4) detects the orientation of the peanut head and determines whether the peanut is defective. If it is defective, it proceeds to step S4. If it is in the wrong orientation, it proceeds to step S5. If it is good and the orientation is correct, it proceeds to step S6. S4: The rejecting nozzle (52) in the bidirectional rejecting device (5) rejects defective peanuts from the round belt conveyor line (3) through the first rejecting port (54) on the cross slot (51); S5: The ejection nozzle (52) in the bidirectional ejection device (5) ejects and collects peanuts with the wrong embryo head direction from the round belt conveyor line (3) through the second ejection port (55) on the cross slot (51), and then enters step S1; S6: The unloading section (6) transfers the peanuts delivered to the end of the round belt conveyor line (3) to the interval conveyor belt (75) in the interval conveyor line (7); S7: The interval conveyor belt (75) in the middle of the interval conveyor line (7) conveys peanut seeds at equal intervals; S8: The unloading assembly (72) unloads the peanut seeds on the interval conveying belt (75) onto the heat sealing mechanism (82); S9: The U-shaped limit card (86) moves the unloaded seeds to the bottom of the heat sealing mechanism (82) and is located between the two layers of water-soluble sealing films. The heat sealing block (89) moves downward to heat-seal the peanuts between the two layers of water-soluble sealing films.
