Description

Technical Field

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

[0002] Peanuts are important cash crops and oil crops. Developing peanut production has become one of the important ways to increase agricultural efficiency and farmers' income. There are various sowing methods for peanuts, including strip sowing and hill sowing. Hill sowing is a method of digging holes in the field according to a certain row spacing and hole spacing for sowing. Hill sowing is relatively laborious and is suitable for small-area or special plot planting.

[0003] Strip sowing is a relatively common method in peanut planting. In this method, a seeding machine or manual furrowing is used to sow peanut seeds (hereinafter referred to as seeds) into the soil according to a certain row spacing and plant spacing, and then the peanuts are buried with soil. Generally, two to three peanut seeds are placed at the same position. After germination, the strongest seedlings are selected and left. This method is conducive to field management and mechanized operation, and is also conducive to the development of peanut roots and the formation of pods. However, this method has the following problems: Problem 1: It is difficult to precisely control the interval between seeds, resulting in uneven growth and affecting the peanut yield; Problem 2: The embryo heads of the seeds are in different directions. The germination rate of peanuts mainly depends on the position of the peanut embryo in the soil. If the peanut embryo head is facing down, its germination rate will increase significantly, while if the peanut embryo head is facing up, its germination rate will be lower.

[0004] Based on this, a device that can assist in planting and control the spacing and embryo head orientation of peanut seeds is needed. In response to the above problems, our side has 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 convey peanut seeds onto the main conveying mechanism. At the same time, the material blocking mechanism in the feeding part is used to initially control the interval between each seed. The visual judgment part and the rejection part are also used to judge and reject unqualified peanut seeds to ensure the quality of each seed. The shunting part arranged on one side of the main conveying mechanism is used to shunt the seeds on the main conveying mechanism to the shunt conveying mechanism. The interval between each seed is precisely controlled by multiple groups of shunt conveying mechanisms distributed at intervals to ensure uniform growth of peanuts. The feeding part is used to transfer the seeds in the shunt conveying mechanism to the positioning and loading part, and then the position adjustment mechanism in the feeding 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 and loading part is used to encapsulate the seeds shunted and transmitted by multiple groups of shunt conveying mechanisms together at the same interval and in the same direction with a water-soluble film. During sowing, the whole strip can be directly sown, ensuring the interval between seeds, ensuring the same embryo head orientation, and improving the germination rate while also increasing the planting speed.

[0005] The technical solution of this patent can achieve seed interval control and adjustment of the same orientation of the embryo head, but the structure is relatively complex and the cost is relatively high. At the same time, this solution uses a material blocking mechanism and a cylinder to push the material. However, due to the unstable position of the peanuts, it often causes the peanuts to get stuck at the material blocking mechanism, that is, the material jamming phenomenon, resulting in the actual interval not reaching the ideal expectation. Or during the process of the cylinder pushing, the position or direction changes, causing the peanuts to get stuck at the interface, thus failing to directly proceed with the subsequent process, which is inconvenient to use.

[0006] At the same time, this solution uses an ordinary conveyor belt for transportation. However, due to interference from friction or other external factors, the ordinary conveyor belt is very likely to cause the direction of the peanuts to change subsequently even though the peanuts have been initially positioned, resulting in deviations in the subsequent entire process and packaging.

[0007] Therefore, based on the applicant's existing patent (Patent No.: CN202411097202.2, Title: Peanut Seed Automatic Positioning Loading System and Loading Method), this invention improves the technical problems of "easy material jamming", "easy deviation of seed position" and "high cost" existing in the use process. Summary of the Invention

[0008] The first technical problem to be solved by this invention is the problem that the existing device mentioned in the background technology is prone to material jamming and the seed position is prone to deviation. The second technical problem to be solved by this invention is the problem that the existing device mentioned in the background technology has a complex structure, high use cost and inconvenient use.

[0009] To solve the above first technical problem, a peanut seed directional loading system is proposed; it is realized through the following technical solutions: A peanut seed directional loading system includes a feeding part, a circular belt conveyor line, a discharging part, an interval conveyor line and a sealing and loading part; the feeding part is arranged on the ground, the feeding part includes a discharging end, the feeding part arranges peanut seeds horizontally at the discharging end, the circular belt conveyor line is arranged at the discharging end, the feeding part transports the arranged peanut seeds to the circular belt conveyor line, there are V-shaped placement grooves on the circular belt conveyor line, the peanut seeds are placed in the V-shaped placement grooves, and the circular belt conveyor line can controllably drive the peanut seeds to be stably transported; a visual judgment part and a two-way material removal device are arranged on the circular belt conveyor line, the two-way material removal device is connected to the visual judgment part, the visual judgment part detects and judges the embryo head orientation of the peanut seeds on the V-shaped placement grooves and the defective products among the peanut seeds, and the two-way material removal device removes the defective products and the peanut seeds with wrong orientations respectively; the discharging part and the interval conveyor line are arranged in the sealing and loading part, the discharging part is located at the end of the circular belt conveyor line, and the peanut seeds at the end of the circular belt conveyor line move to the interval conveyor line under the action of the discharging part, and the interval conveyor line transports the peanut seeds at equal intervals to the heat sealing mechanism in the sealing and loading part for packaging. The sealed loading part includes an installation frame, an installation plate, and a heat-sealing mechanism. The installation plate is arranged on the installation frame, and a second linear slide rail pair is arranged on the installation plate. The heat-sealing mechanism for peanut seed packaging is arranged on the second linear slide rail pair. The heat-sealing mechanism includes a substrate, a fixing plate, a heat-sealing block, and a moving plate. The substrate is connected to the second linear slide rail pair, the fixing plate is arranged on the substrate, the heat-sealing block for heat-sealing is arranged on the moving plate, the moving plate is movably connected to the fixing plate, and the moving plate can be controllably lifted and lowered relative to the fixing plate to heat-seal the water-soluble sealing film arranged on the heat-sealing block and the substrate. A limiting air rod and a U-shaped limiting card are arranged on the substrate. The U-shaped limiting card is arranged on the limiting air rod. The peanut seeds on the intermittent conveyor line are moved to the inside of the U-shaped limiting card through the discharging assembly on the intermittent conveyor line. The U-shaped limiting card conveys the peanut seeds to below the heat-sealing block and is located between two layers of water-soluble sealing films.

[0010] Preferably, for the technical solution of the present invention, the feeding part includes a vibrating feeding tray. An outlet end is arranged on the vibrating feeding tray. The peanut seeds vibrate and align in the vibrating feeding tray and gradually move to the outlet end. A discharging plate is arranged at the outlet end. The peanut seeds moving to the outlet end are transversely arranged on the discharging plate. The arrangement of the discharging plate facilitates the same-direction arrangement of the peanut seeds moving to the outlet end, avoids adjusting the orientation of the peanut seeds in the later stage, and has a simple structure and is convenient to use.

[0011] Preferably, for the technical solution of the present invention, the vibration frequency at the outlet end is different from that inside the vibrating feeding tray. The distance between adjacent peanut seeds on the discharging plate is greater than the distance between adjacent peanut seeds inside the vibrating feeding tray. Such an arrangement facilitates increasing the interval distance between individuals when the peanuts are discharged, which is convenient for subsequent transportation and shooting recognition.

[0012] Preferably, for the technical solution of the present invention, the circular belt conveyor line includes a receiving tray. The receiving tray includes a receiving port. The receiving tray is arranged at one end of the circular belt conveyor line. The peanut seeds transversely arranged on the vibrating feeding tray fall into the receiving tray from the receiving port and are guided by the receiving tray to fall transversely into the V-shaped placement groove. The arrangement of the receiving tray facilitates the peanut seeds to fall into the V-shaped placement groove through the receiving tray. The arrangement of the V-shaped placement groove facilitates restricting the peanut seeds after the orientation adjustment through the V-shaped placement groove, preventing the direction of the peanut seeds from changing during the conveying process, and preventing problems such as deviations in the subsequent entire process and packaging.

The detection camera detects the peanut seeds passing on the circular belt conveyor line. The bidirectional material rejection device includes a cross groove and a serpentine pipe equipped with a material rejection nozzle. The cross groove is arranged on the circular belt conveyor line, below the conveying circular belt in the circular belt conveyor line. There are two serpentine pipes, which are respectively arranged in two opposite guide grooves of the cross groove. The material rejection nozzles on the two serpentine pipes respectively reject the seeds with wrong embryo head orientation and the defective seeds on the conveying circular belt. The setting of the visual judgment part is convenient for detecting the seeds with wrong orientation and defective seeds on the circular belt conveyor line. The setting of the bidirectional material rejection device is convenient for respectively rejecting the defective products and the seeds with wrong embryo head orientation among the peanut seeds. The structure is simple and the use is convenient and fast.

[0014] For the optimization of the technical solution of the present invention, the feeding part includes a first linear slide rail pair, a pneumatic gripper and a lifting push rod. The lifting push rod is arranged on the first linear slide rail pair, and the pneumatic gripper is arranged on the lifting push rod. The pneumatic gripper moves controllably along the first linear slide rail pair under the action of a motor, and clamps the peanut seeds at the end of the circular belt conveyor line to the intermittent conveyor line. Such a setting is convenient for transporting the peanut seeds with the same embryo head direction to the intermittent conveyor line, which is convenient for later packaging and is easy to use.

[0015] For the optimization of the technical solution of the present invention, the intermittent conveyor line includes an intermittent conveyor belt and a discharging assembly. The intermittent conveyor belt is arranged on the sealed loading part through a driving motor. Intermittent blocks are arranged at intervals on the intermittent conveyor belt. A placement cavity is formed between two adjacent intermittent blocks. The peanut seeds are placed in the placement cavity. The discharging assembly is arranged on the sealed loading part, near the end of the intermittent conveyor belt. The discharging assembly controllably unloads the peanut seeds from the intermittent conveyor belt. The setting of the intermittent conveyor line is convenient for stably transporting the peanut seeds with the same direction to the heat sealing mechanism, ensuring the stability of the direction of the peanut seeds during the transportation process and being easy to use.

[0016] In response to the above second technical problem, the present application also proposes a loading method for a peanut seed directional loading system; it is realized through the following technical solutions: a loading method for a peanut seed directional loading system, characterized by including the following steps: S1: Select peanuts of appropriate size and place them in the vibrating feeding tray; S2: The vibrating feeding tray vibrates and feeds the peanuts in the tray to the discharging end, adjusts them to be arranged horizontally at intervals on the discharging plate, and then feeds them onto the circular belt conveyor line; S3: The visual judgment part detects the orientation of the peanut heads and judges whether the peanuts are defective products. When they are defective products, enter step S4. When the orientation is wrong, enter step S5. When they are good products and the orientation is correct, enter step S6; S4: In the two-way material rejection device, the material rejection nozzle removes defective peanuts from the circular belt conveyor line through the first material rejection opening on the cross groove. S5: In the two-way material rejection device, the material rejection nozzle removes and collects peanuts with incorrect embryo head directions from the circular belt conveyor line through the second material rejection opening on the cross groove, and then proceeds to step S1. S6: The feeding section transfers the peanuts conveyed to the end of the circular belt conveyor line to the intermittent conveyor belt in the intermittent conveyor line. S7: The intermittent conveyor belt in the intermittent conveyor line conveys peanut seeds at equal intervals. S8: The discharging assembly discharges the peanut seeds on the intermittent conveyor belt onto the heat sealing mechanism. S9: The U-shaped limit clamp moves the unloaded seeds under the heat sealing mechanism and between two layers of water-soluble sealing films. The heat sealing block moves downward to heat-seal the peanuts between the two layers of water-soluble sealing films.

[0017] The beneficial effects of the present invention compared with the prior art are as follows: In the technical solution of the present invention, the feeding section automatically feeds the seeds in an orderly manner, arranges the orientations of the seeds on the discharge plate at the discharge end, and feeds the seeds with the same arranged orientation onto the circular belt conveyor line. At the same time, the V-shaped placement grooves on the circular belt conveyor line are used to place the seeds, ensuring the stability of the seeds during the conveying process and preventing the direction of the seeds from changing during the conveying process, which may lead to deviations in the subsequent entire process and packaging. The visual judgment section provided on the circular belt conveyor line detects the embryo head orientations and defective products of the seeds, and the two-way material rejection device is used to remove the seeds with incorrect orientations and defective products respectively. It is convenient to use. The feeding section moves the seeds transferred to the end of the circular belt conveyor line to the intermittent conveyor line, and the seeds are conveyed at equal intervals to the heat sealing mechanism in the sealing and loading section through the intermittent conveyor line. The seeds are packaged by the heat sealing mechanism. The structure is simple and the use is convenient and fast. Description of the Drawings

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be described in detail in conjunction with the accompanying Figure 1-16 drawings of the embodiments of the present invention.

[0020] Embodiment

[0021] As Figure 1 shown, a peanut seed directional loading system includes a control unit 1, a loading section 2, a round belt conveyor line 3, a visual judgment section 4, a two-way material rejection device 5, an unloading section 6, an intermittent conveyor line 7, a sealed loading section 8, and a sealed film assembly 9.

[0022] 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 respectively. The control unit 1 is an existing device and can be directly used.

[0023] The main function of the feeding section 2 is to automatically feed seeds in an orderly manner. At the same time, the feeding section 2 can also arrange the seeds, arranging the seeds horizontally to facilitate subsequent visual recognition and packaging.

[0024] The main function of the circular belt conveyor line 3 is to convey the seeds after horizontal arrangement. The front end of the circular belt conveyor line 3 is connected to the feeding section 2. The circular belt conveyor line 3 ensures the stability of the seeds during the conveying process to prevent the seeds from shifting during the conveying process. At the same time, the circular belt conveyor line 3 also serves as the carrier for installing the visual judgment section 4 and the two-way material rejection device 5.

[0025] The main function of the visual judgment section 4 is to take pictures and identify the seeds passing below the visual judgment section 4 to facilitate the detection and judgment of defective products in the seeds and confirm the orientation of the seed embryo heads.

[0026] The main function of the two-way material rejection device 5 is to reject defective products in the seeds and seeds with incorrect embryo head orientations according to the judgment results of the visual judgment section 4.

[0027] The main function of the discharging section 6 is to move the seeds conveyed to the end of the circular belt conveyor line 3 onto the intermittent conveyor line 7, and use the intermittent 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 and loading section 8 to package the seeds with determined orientations and intervals.

[0028] The main function of the sealing film assembly 9 is to provide a water-soluble heat-sealing film, and use the water-soluble heat-sealing film to package the seeds, which is convenient to use. 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.

[0029] As Figure 1 、 2 As shown in Figures 2 and 3, the feeding section 2 includes a vibrating feeding tray 21 and a feeding tray mounting frame 22. The feeding tray mounting frame 22 is placed on the ground, and the vibrating feeding tray 21 is connected to the feeding tray mounting frame 22. The feeding tray mounting frame 22 is a rectangular metal frame welded by square pipes, and its main function is to serve as the base for installing the vibrating feeding tray 21.

[0030] The vibrating feeding tray 21 is a spiral feeding device using vibration feeding. The technology and equipment for vibration feeding are existing devices that can be used directly. In order to facilitate the arrangement of the seeds and make the seeds arranged horizontally, a rectangular discharging plate 25 is integrally fixed at the discharging end 23 of the vibrating feeding tray 21.

[0031] A rectangular metal sheet is fixed to the side of the discharge end 23 by screws. This metal sheet is named the limit partition 24. The limit partition 24 separates the discharge end 23, creating a smaller discharge channel with a "U"-shaped cross-section at the discharge end 23. Moreover, the width dimension of the channel is adjustable by adjusting the position of the limit 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 inside the vibrating feeding tray 21 and reach the discharge end 23, they are laterally sorted on the discharge plate 25 under the restriction of the discharge channel.

[0032] To preliminarily adjust the interval between seeds, in this embodiment, the vibrating feeding tray 21 is preferably a multi-vibration-source feeding tray. The vibration frequency inside the vibrating feeding tray 21 is different from the vibration frequency at the discharge end 23. By adjusting the vibration frequency, the interval between adjacent seeds at the discharge end 23 is made larger than the interval between seeds inside the vibrating feeding tray 21.

[0033] Definition: In this embodiment, with the ground as the reference, the direction from the ground to the equipment is defined as the upward direction, and the direction from the embryo head end of the peanut seed to the other end and the same as the conveying direction of the interval conveyor 7 is defined as the lateral direction.

[0034] As Figure 1 、 4 As shown in 5 and 6, the circular belt conveyor 3 includes a conveyor frame 31, support legs 34, a conveyor motor 32, conveyor wheels 35, and a conveyor circular belt 37. The conveyor frame 31 is connected to the support legs 34. The circular belt conveyor 3 is placed on the ground through the support legs 34. There are two conveyor wheels 35, which are respectively arranged at both ends of the conveyor frame 31. The two conveyor wheels 35 are connected by the conveyor circular belt 37. The conveyor motor 32 is arranged at one end of the conveyor frame 31 and is connected to one of the conveyor wheels 35. By driving the conveyor wheel 35 through the conveyor motor 32, the conveyor circular belt 37 can be driven to move, thus completing the conveying of the seeds.

[0035] The conveyor frame 31 is a rectangular metal plate. There are two conveyor frames 31, and the two conveyor frames 31 are connected to each other in an opposite and parallel manner through a rectangular connecting block. The main function of the conveyor frame 31 is to serve as a carrier for installing the conveyor wheels 35. To facilitate the stable placement of the conveyor frame 31, a support leg 34 is fixed to the lower end of the conveyor frame 31 by screws, and the conveyor frame 31 is placed on the ground through the support leg 34.

[0036] The conveyor wheel 35 is a rubber wheel with a circular cross-section. The conveyor wheel 35 is fixed to both ends of the conveyor frame 31 through bearings and connecting shafts, and the conveyor wheel 35 can rotate freely along the connecting shaft.

[0037] To facilitate the installation of the conveying round belt 37, two circular grooves are concavely formed on the arc surface of the conveying wheel 35. The conveying round belt 37 is placed in these grooves. The two conveying wheels 35 are connected by the conveying round belt 37. When one conveying wheel 35 rotates, the other conveying wheel 35 will also rotate under the action of the conveying round belt 37. To facilitate driving the conveying wheel 35 to rotate, a conveying motor 32 is fixed on the conveying frame 31 with screws. The conveying motor 32 is connected to the conveying wheel 35 at one end of the conveying frame 31. The connection method can be selected from existing common connection methods, such as gear connection. The conveying motor 32 drives the conveying round belt 37 to move to realize the conveying of seeds.

[0038] The conveying round belt 37 is a conveyor belt with a circular cross-section. To ensure the stability of operation, the conveying round belt 37 is preferably supported by rubber material. Two groups of conveying round belts 37 are arranged on the conveying wheel 35. The two groups of conveying round belts 37 are parallelly distributed on the conveying wheel 35 and have a certain interval. In this embodiment, the preferred interval is 3 mm. Since both conveying round belts 37 are circular and there is a certain interval between the two conveying round belts 37, a V-shaped space is formed between the two conveying round belts 37. This space is named the V-shaped placement groove 39, and the seeds are placed in the V-shaped placement groove 39.

[0039] To facilitate the stable placement of seeds from the feeding part 2 onto the round belt conveying line 3, a receiving tray 33 is fixed on the front end of the round belt conveying line 3 with screws. The receiving tray 33 is rectangular as a whole and is fixed on the conveying frame 31. The receiving tray 33 is located above the conveying round belt 37. Through holes are formed on the lower surface of the receiving tray 33, and the seeds can fall through these through holes onto the conveying round belt 37 below. To facilitate receiving materials, the four surfaces of the receiving tray 33 are inclined. These four inclined surfaces are named baffles 310. The seeds falling into the receiving tray 33 can be guided by the baffles 310, which is convenient for the seeds to fall onto the conveying round belt 37 below. To facilitate receiving and feeding materials, a receiving opening 36 and a discharging opening 38 are respectively formed on the two baffles 310 perpendicular to the conveying round belt 37 on the receiving tray 33. The seeds fall into the receiving tray 33 from the receiving opening 36, are guided by the baffles 310 and then fall onto the conveying round belt 37, and are then transported out through the discharging opening 38 for conveying.

[0040] Definition: During the transportation of seeds by the round belt conveying line 3, the seeds are transported from one end where the receiving tray 33 is provided to the other end. The end where the receiving tray 33 is provided is the front end, and the other end is the end.

[0041] Such as Figure 1 And 7As shown in the figure, 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 bracket made of sheet metal. Its main function is to mount the detection camera 41. The camera mounting bracket 42 is fixed on the conveying frame 31 near the middle with screws, and the detection camera 41 is fixed on the camera mounting bracket 42 with screws. The detection camera 41 is located above the conveying circular belt 37. All the seeds passing through the conveying circular belt 37 are photographed by the detection camera 41 and are judged and identified by the control unit 1.

[0042] Regarding the visual judgment principle of the peanut seed head and tail by the detection camera 41, in this embodiment, the classification model of YOLOV8 is adopted. YOLOV8 is a deep - learning model based on object detection. It is the latest version of the YOLO (You Only Look Once) series of models. YOLOV8 adopts an end - to - end training method based on the Convolutional Neural Network (CNN) and can detect multiple targets in an image simultaneously. After the peanut seeds reach a fixed position, the detection camera 41 takes pictures to perform visual detection on the half - exposed peanuts. After the detection is completed, a comparison is made, and an exact value is returned to the peanut belt to determine the forward direction of the peanuts on the circular belt conveyor 3. In addition, the orientation of the embryo head needs to be set in the control unit 1. For example, if the forward direction of the embryo head is set as the preset direction, then during the visual detection process, the seeds with the embryo head facing backward are defined as seeds with incorrect orientation. At the same time, during the peanut visual discrimination process, if seeds with unclear or damaged heads or tails are found, they are defined as defective products, providing a basis for subsequent mechanical operations.

[0043] Regarding the photographing control of the seeds by the detection camera 41, an infrared sensor is provided on the conveying frame 31. When the infrared sensor detects that a seed has passed by, it triggers the detection camera 41 to take pictures. This is a mature existing technology and will not be elaborated here.

[0044] As Figure 1 and 7 shown, the two - way material rejection device 5 includes a cross - slot 51 and a material rejection nozzle 52. The material rejection nozzle 52 is installed on the cross - slot 51 through a serpentine tube 56, and the material rejection nozzle 52 is used to separately reject the seeds with incorrect orientation and defective products.

[0045] The cross-shaped groove 51 is a cross-shaped chute formed by bending a metal plate. The four ports of the cross-shaped groove 51 are respectively named as the serpentine tube installation ports and the material removal ports. 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-shaped groove 51, a rectangular groove is opened perpendicular to the surface of the cross-shaped groove 51, and this groove is named as the round belt clearance groove 53. After the cross-shaped groove 51 is fixed on the conveying frame 31 by screws, the conveying round belt 37 is placed at the round belt clearance groove 53, that is, the cross-shaped groove 51 is located below the conveying round belt 37, and the conveying round belt 37 passes over the cross-shaped groove 51.

[0046] For the convenience of 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 an air pump, and the position of the material removal nozzle 52 can be adjusted through the serpentine tube 56 so that both material removal nozzles 52 are corresponding to the conveying round belt 37 and the material removal ports.

[0047] There are two material removal ports, which are respectively named as the first material removal port 54 and the second material removal port 55. One material removal nozzle 52 corresponds to the first material removal port 54, and the other material removal nozzle 52 corresponds to the second material removal port 55. The defective products can be blown off from the conveying round belt 37 by the material removal nozzle 52 and the compressed air in the air pump and discharged from the first material removal port 54. The seeds with wrong orientation can be blown off from the conveying round belt 37 by the other material removal nozzle 52 and discharged from the second material removal port 55, and the seeds removed through the second material removal port 55 can be repeatedly placed for use in the feeding part 2.

[0048] Regarding the switch control of the material removal nozzle 52 for material removal: The switch of the material removal nozzle 52 is controlled by the control part 1, and the control part 1 controls the switches of different material removal nozzles 52 according to the judgment result of the visual judgment part 4, which is convenient to use.

[0049] As Figure 14 and 15 shown, in order to conveniently place the seeds removed from the second material removal port 55 back into the feeding part 2 for repeated use, in this embodiment, preferably, a material return mechanism 10 is placed at the second material removal port 55 close to the round belt conveying line 3. The material return mechanism 10 is placed on the ground, and the upper end of the material return mechanism 10 is located above the vibrating feeding tray 21. Through the material return mechanism 10, the seeds removed from the second material removal port 55 can be re-conveyed into the vibrating feeding tray 21, which is convenient for the seeds with wrong orientation to continue to flow back for use.

[0050] The material return mechanism 10 includes a Z-shaped material return frame 101, an aggregate tray 102 and a feeding belt 104. The aggregate tray 102 and the feeding belt 104 are installed on the material return frame 101, and the aggregate tray 102 is located at the lower end of the material return frame 101. The peanut seeds with wrong orientation removed from the second material removal port 55 fall into the aggregate tray 102 and are transported to the upper end of the material return frame 101 by the feeding belt 104, and then fall into the vibrating feeding tray 21.

[0051] 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 frame 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 at the contact point between the collecting tray 102 and the feeding belt 104.

[0052] 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 conveying roller is installed at each end of the return material rack 101. The conveying roller is a circular transmission roller. The two ends of the conveying roller are installed on the return material rack 101 through bearings. The feeding belt 104 is sleeved on the outside of the conveying roller. In order to facilitate the driving of the conveying roller, a motor is fixed at 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 conveying roller at the lower end of the return material rack 101 through a gear. The return material motor 105 can drive the conveying roller to rotate, thereby driving the feeding belt 104 to move.

[0053] 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 manual transportation of the seeds blown off at the second ejection port 55 back to the vibrating loading tray 21.

[0054] like Figure 1 and 8 As shown, the unloading part 6 includes a unloading part mounting frame 61, a first driving 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 driving 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.

[0055] The main function of the blanking part mounting frame 61 is to mount various components in the blanking part 6. The blanking part mounting frame 61 is entirely made of metal sheet metal. The first linear slide rail pair 63 is installed on the blanking part mounting frame 61 using screws, and the first drive motor 62 is installed on the blanking part mounting frame 61 using screws and is located at one end of the first linear slide rail pair 63.

[0056] To facilitate controlling the movement of the pneumatic gripper 65 through the first drive motor 62, a pulley is fixed at the other end of the blanking part mounting frame 61. 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 sleeved on the two first pulleys 64, and the first drive motor 62 can drive the belt 67 to move.

[0057] To facilitate adjusting the height of the pneumatic gripper 65, a lifting push rod 66 is fixed on the slider in the first linear slide rail pair 63 using screws. The pneumatic gripper 65 is connected to the lifting push rod 66 using screws. The height of the pneumatic gripper 65 can be adjusted through the lifting push rod 66. Additionally, a fixing pressing piece is arranged on the lifting push rod 66 using screws, and the fixing pressing piece is connected to the belt 67 using screws. The belt 67 drives the lifting push rod 66 to move along the first linear slide rail pair 63.

[0058] The pneumatic gripper 65 is a pneumatically driven gripper in the prior art and can be directly used as an existing device. To prevent the pneumatic gripper 65 from damaging the seeds, sponge protective sleeves are sleeved on both jaws of the pneumatic gripper 65 to protect the seeds using the sponge protective sleeves.

[0059] When the seeds are transported to the end of the circular belt conveyor 3, to facilitate the timely blanking of the blanking part 6, a second camera 68 is fixed on the blanking part mounting frame 61 at one end of the blanking part 6 close to the circular belt conveyor 3 using screws. The second camera 68 is connected to the second control box 12 in the control part 1. The transported seeds can be positioned through the second camera 68, facilitating the pneumatic gripper 65 to pick up and blank. Additionally, the method of positioning by taking pictures with the camera is an existing technology and can be directly used.

[0060] Regarding the movement of the pneumatic gripper 65: When the seeds are identified as qualified seeds by the vision judgment part 4, the pneumatic gripper 65 in the blanking part 6 moves to a position close to the circular belt conveyor 3 at the end of the blanking part 6. When the seeds are transported, the pneumatic gripper 65 picks up the seeds with the assistance of the second camera 68 taking pictures.

[0061] Such as Figure 1 、 9As shown in FIGS. 9 and 10, the intermittent conveyor line 7 includes a second drive motor 71 and an intermittent conveyor belt 75. The second drive motor 71 is installed on the mounting plate 83 in the sealed loading section 8. The intermittent conveyor belt 75 is connected to the second drive motor 71. The second drive motor 71 can drive the intermittent conveyor belt 75 to move, thereby transporting the seeds to the heat sealing mechanism 82 in the sealed loading section 8 for encapsulation.

[0062] For the convenience of installing the intermittent conveyor belt 75, a second pulley 73 is fixed on the mounting plate 83 by a pulley mounting bracket 74. The pulley mounting bracket 74 is a "U"-shaped metal bracket made of sheet metal. The pulley mounting bracket 74 is fixed on the mounting plate 83 by screws. The second pulley 73 is pinned to the pulley mounting bracket 74, and the second pulley 73 can rotate freely along the pinned joint.

[0063] A second pulley 73 is also fixed on the output shaft of the second drive motor 71. The two ends of the intermittent conveyor belt 75 are respectively sleeved on the two second pulleys 73 to achieve transmission.

[0064] The intermittent conveyor belt 75 is a circular transmission belt. Tooth teeth are provided on the inner side surface of the intermittent conveyor belt 75. The intermittent conveyor belt 75 meshes with the second pulley 73 through the tooth teeth. For the convenience of transporting seeds at equal intervals and restricting the position of the seeds during the transportation process to prevent the deviation of the seed position, a plurality of spacer blocks 76 are fixedly spaced on the outer surface of the intermittent conveyor belt 75. The spacer blocks 76 are rectangular blocks, and the spacer blocks 76 are integrally connected with the intermittent conveyor belt 75. The plurality of spacer blocks 76 are evenly distributed on the intermittent conveyor belt 75. A placement cavity for placing seeds is formed between two adjacent spacer blocks 76. The pneumatic gripper 65 places the seeds in the placement cavity and transports them to the heat sealing mechanism 82 in the sealed loading section 8 through the second drive motor 71.

[0065] When the seeds are transported to the heat sealing mechanism 82, for the convenience of unloading, a unloading assembly 72 is further provided on the mounting plate 83. The main function of the unloading assembly 72 is to unload the seeds on the intermittent conveyor line 7 to the heat sealing mechanism 82. It can unload materials by using the same structure as the feeding section 6 or use the unloading assembly 72 for unloading, which can be selected according to the actual use situation. In the attached drawings of this embodiment, the unloading assembly 72 is used for unloading.

[0066] The unloading assembly 72 includes a unloading rod 77 and a unloading piece 78 fixed at the end of the unloading rod 77. The unloading rod 77 is a pneumatic push rod. The unloading rod 77 is fixed on the mounting plate 83 by 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 intermittent conveyor line 7 can be pushed down through the unloading piece 78 and the unloading rod 77 to complete the unloading.

[0067] As Figure 1 、11 As shown in Figures 12 and 13, the sealed loading part 8 includes a mounting frame 81, a mounting plate 83, a second linear slide rail pair 84, a limit air rod 85 and a heat sealing mechanism 82. The mounting plate 83 is fixed on the mounting frame 81, the second linear slide rail pair 84 is arranged on the mounting plate 83, and the limit air rod 85 and the heat sealing mechanism 82 are connected to the second linear slide rail pair 84.

[0068] The mounting frame 81 is a metal frame assembled by 30*30 aluminum profiles. Its main function is to serve as a carrier for installing various components in the sealed loading part 8, and the mounting frame 81 is placed on the ground.

[0069] 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 groups of second linear slide rail pairs 84 are fixed on the mounting plate 83 by screws, and the two groups of second linear slide rail pairs 84 are distributed in parallel on the mounting plate 83.

[0070] The main function of the second linear slide rail pair 84 is to facilitate the movement of the heat sealing mechanism 82 along the second linear slide rail pair 84, which is convenient for placing seeds between two layers of water-soluble sealing films and for the heat sealing mechanism 82 to package the seeds.

[0071] The heat sealing mechanism 82 includes a base plate 87, a fixing plate 88, a moving plate 811, a heat sealing block 89, a screw motor 812 and a guide rod 813.

[0072] The base plate 87 is a rectangular plate made of metal. The base plate 87 is connected to the sliders on two groups of second linear slide rail pairs 84 by screws. Two circular guide rods 813 are fixed on the upper surface of the base plate 87 by screws. A rectangular fixing plate 88 is fixed on the upper ends of the two guide rods 813 by screws, and a screw motor 812 is fixed on the fixing plate 88 by screws.

[0073] The moving plate 811 is a rectangular metal plate. Two flanged linear bearings are fixed at both ends of the moving plate 811 by screws. The linear bearings can cooperate with the guide rods 813, enabling the moving plate 811 to move up and down along the guide rods 813. To facilitate the control of the up and down movement of the moving plate 811, a flanged nut is fixed on the moving plate 811 by screws. The flanged nut cooperates with the screw on the screw motor 812, and under the action of the screw motor 812, the moving plate 811 can move controllably up and down along the guide rods 813.

[0074] 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. To facilitate heat sealing, the heat sealing block 89 is connected to the lower surface of the moving plate 811 by screws. Two circular mounting openings are provided on the surface of the heat sealing block 89, and two circular heating rods are inserted into the mounting holes. The heat sealing block 89 can be heated by the heating rods, which is convenient for heat-sealing the seeds.

[0075] To make way for the seeds and facilitate the encapsulation of the seeds by the heat-sealing block 89, a rectangular groove is recessed on the lower surface of the heat-sealing block 89, and this groove is named the relief groove 810. When the heat-sealing block 89 presses down for heat-sealing the seeds, the seeds are located within the relief groove 810, preventing the heat-sealing block 89 from squeezing the seeds and causing damage to the seeds.

[0076] There are two layers of water-soluble sealing films on the upper surface of the substrate 87. To facilitate the movement of the seeds to be encapsulated between the two layers of water-soluble sealing films, a limit air rod 85 is fixed to the substrate 87 with screws. The limit air rod 85 is a retractable push rod driven by air pressure. A U-shaped limit clamp 86 is fixed to the end of the limit air rod 85 with screws. The unloading assembly 72 pushes the seeds from the spaced conveying line 7 and drops them into the U-shaped limit clamp 86. The U-shaped limit clamp 86 restricts the direction of the seeds. After the limit air rod 85 moves with the substrate 87 between the two layers of water-soluble sealing films on the second linear slide rail pair 84, the limit air rod 85 contracts, leaving the seeds between the water-soluble sealing films, facilitating heat-sealing by the heat-sealing block 89.

[0077] To facilitate the control of the movement of the substrate 87 along the second linear slide rail pair 84, a telescopic push rod (not shown in the figure) is fixed to the substrate 87 with screws. The telescopic push rod can drive the substrate 87 to move linearly along the second linear slide rail pair 84, thereby moving the seeds between the two layers of water-soluble sealing films and facilitating the heat-sealing of the seeds by the heat-sealing block 89.

[0078] As Figure 1 、 12 shown in 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. Both the first water-soluble sealing film 91 and the second water-soluble sealing film 92 are in the form of circular rolls, and their main function is to encapsulate peanut seeds.

[0079] To facilitate the fixation 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 to the mounting frame 81 with 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.

[0080] Regarding the mounting 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 mounted on the same side of the mounting frame 81, and the second water-soluble sealing film 92 is located above the mounting frame 81.

[0081] Regarding the positional relationship of the first water-soluble sealing film 91 and the second water-soluble sealing film 92 on the heat-sealing mechanism 82, and the directional setting of the first water-soluble sealing film 91 and the second water-soluble sealing film 92, a sealing film guide rod 94 is also fixed on the installation frame 81 with screws. 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. Among them, the second water-soluble sealing film 92 is laid flat 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 therebetween. Both the first water-soluble sealing film 91 and the second water-soluble sealing film 92 pass through the heat-sealing mechanism 82 and are located below the heat-sealing block 89.

[0082] When 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 limiting strip is fixed on the installation frame 81 with screws, and a rectangular limiting piece 95 is fixed at the end of the limiting strip with glue. The limiting piece 95 is made of rubber. There is a 3-mm gap between the lower end of the limiting piece 95 and the substrate 87. The limiting 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 position 3 mm above the upper surface of the substrate 87, so as to prevent the seeds located between the first water-soluble sealing film 91 and the second water-soluble sealing film 92 from moving.

[0083] Regarding the process of seed encapsulation: Before encapsulation, the unloading assembly 72 unloads the seeds from the spaced conveying belt 75 onto the substrate 87. At this time, the limiting air rod 85 extends, and the unloaded seeds are located within the U-shaped limiting clamp 86 at this time. The position of the seeds is restricted by the U-shaped limiting clamp 86 to prevent the seeds from moving. Then, the telescopic push rod drives the substrate 87 to displace along the second linear slide rail pair 84 (the displacement distance is the distance between two seeds after encapsulation). At this time, the positions of the first water-soluble sealing film 91 and the second water-soluble sealing film 92 remain unchanged, and the U-shaped limiting clamp 86 drives the seeds to move synchronously. After reaching the specified distance, the limiting air rod 85 contracts to release the limitation of the U-shaped limiting clamp 86 on the seeds. Then, the telescopic push rod drives the substrate 87 to displace in the reverse direction along the second linear slide rail pair 84 to reset (during this process, the peanut seeds are between the first water-soluble sealing film 91 and the second water-soluble sealing film 92 and their positions remain unchanged under the action of the limiting piece 95). After resetting, the seeds are located below the heat-sealing block 89. Then, the lead screw motor 812 drives the heat-sealing block 89 to move downward, and the encapsulation of the seeds can be completed.

[0084] This embodiment relates to the control of a loading system: The loading system is controlled by a control unit 1, which includes a first control box 11 and a second control box 12. The first control box 11 is installed on the circular belt conveyor line 3, and the circular belt conveyor line 3, the visual judgment unit 4 and the bidirectional rejection device 5 provided on the circular belt conveyor line 3 are controlled through the first control box 11. The second control box 12 is installed on the sealed loading unit 8, and the blanking unit 6, the intermittent conveyor line 7 and the sealed loading unit 8 are controlled through the second control box 12.

[0085] As Figure 14 and 16 shown, after the heat-sealing mechanism 82 and the water-soluble sealing film encapsulate the seeds, in order to facilitate the bundling of the water-soluble film with seeds after encapsulation, on the other side of the mounting frame 81 away from the first water-soluble sealing film 91, a film winding mechanism 96 is installed, and the film winding mechanism 96 can bundle the water-soluble sealing film after encapsulation.

[0086] The film winding mechanism 96 includes a film winding motor 97, a film winding motor mounting frame 98 and a film winding rod 99. The film winding motor mounting frame 98 is a rectangular plate made of metal. There are two film winding motor mounting frames 98, and the two film winding motor mounting frames 98 are connected by a connecting rod. At the upper end of the film winding motor mounting frame 98, a round rod is installed by using a bearing, and this round rod is named the film winding rod 99. A film winding disc is sleeved on the film winding rod 99, and one end of the water-soluble sealing film at the rear end of the encapsulation is wound on this film winding disc. A motor is fixed on the film winding motor mounting frame 98 by using screws, and this motor is named the film winding motor 97. The film winding motor 97 is connected to the film winding rod 99 through gears. By using the film winding motor 97, the film winding rod 99 and the film winding disc can be driven to rotate, thereby realizing the bundling of the water-soluble sealing film after encapsulation. At the same time, the film winding motor 97 can also drive the disc-shaped first water-soluble sealing film 91 and the second water-soluble sealing film 92 to unwind, facilitating the encapsulation of seeds.

[0087] This embodiment relates to a loading method for a peanut seed directional loading system, which specifically includes the following steps: S1: Select peanuts of appropriate size and place them in the vibrating feeding tray 21; S2: The vibrating feeding tray 21 vibrates and feeds the peanuts in the tray to the discharge end 23, adjusts them to be arranged at horizontal intervals on the discharge plate 25, and then feeds them onto the circular belt conveyor line 3; S3: The visual judgment unit 4 detects the orientation of the peanut heads and judges whether the peanuts are defective products. If they are defective products, go to step S4; if the orientation is incorrect, go to step S5; if they are good products and the orientation is correct, go to step S6; S4: The rejection nozzle 52 in the bidirectional rejection device 5 rejects the defective peanuts from the circular belt conveyor line 3 through the first rejection port 54 on the cross groove 51; S5: In the two-way material rejection device 5, the material rejection nozzle 52 rejects the peanuts with the wrong embryo head direction from the round belt conveyor line 3 through the second material rejection port 55 on the cross groove 51, and uses the material return mechanism 10 to collect and return the materials, and then enters step S1; S6: The blanking part 6 transfers the peanuts conveyed to the end of the round belt conveyor line 3 to the spaced conveyor belt 75 in the spaced conveyor line 7; S7: The spaced conveyor belt 75 in the spaced conveyor line 7 conveys peanut seeds at equal intervals; S8: The unloading assembly 72 unloads the peanut seeds on the spaced conveyor belt 75 onto the heat sealing mechanism 82; S9: The U-shaped limit card 86 moves the unloaded seeds under the heat sealing mechanism 82 and is located between two layers of water-soluble sealing films. The heat sealing block 89 moves downward to heat-seal the peanuts between two layers of water-soluble sealing films.

[0088] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention shall fall within the protection scope of the present invention.

The discharging assembly (72) is arranged on the sealed loading section (8), near the end of the intermittent conveyor belt (75). The discharging assembly (72) controllably unloads the peanut seeds from the intermittent conveyor belt (75).

8. A loading method for a peanut seed directional loading system according to any one of claims 1-7, characterized in that It includes the following steps: S1: Select peanuts of appropriate size and place them into the vibrating feeding tray (21). S2: The vibrating feeding tray (21) vibrates and feeds the peanuts in the tray to the discharge end (23), adjusts them to be arranged horizontally at intervals on the discharge plate (25), and then feeds them onto the circular belt conveyor line (3); S3: The visual judgment unit (4) detects the orientation of the peanut heads and judges whether the peanuts are defective products. If they are defective products, it enters step S4; if the orientation is incorrect, it enters step S5; if they are good products and the orientation is correct, it enters step S6; S4: The ejection nozzle (52) in the two-way ejection device (5) ejects the defective peanuts from the circular belt conveyor line (3) through the first ejection port (54) on the cross groove (51); S5: The ejection nozzle (52) in the two-way ejection device (5) ejects and collects the peanuts with the wrong embryo head direction from the circular belt conveyor line (3) through the second ejection port (55) on the cross groove (51), and then enters step S1; S6: The blanking unit (6) transfers the peanuts conveyed to the end of the circular belt conveyor line (3) to the intermittent conveyor belt (75) in the intermittent conveyor line (7); S7: The intermittent conveyor belt (75) in the intermittent conveyor line (7) conveys the peanut seeds at equal intervals; S8: The unloading assembly (72) unloads the peanut seeds on the intermittent conveyor belt (75) onto the heat-sealing mechanism (82); S9: The U-shaped limit clamp (86) moves the unloaded seeds under the heat-sealing mechanism (82) and between 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.
