Description

Technical Field

[0001] The invention relates to the field of seed film seeding equipment, and more specifically, to an automated seed film production equipment. Background Art

[0002] The new two-stage intelligent direct seeding technology for rice, namely indoor automated precision spot film making and field mechanical film laying, is a new rice cultivation technology invented by Guangdong University of Technology and its joint research team in recent years. Compared with traditional cultivation technology, direct seeding with film covering has higher seeding efficiency, and the row and plant spacing can be accurately positioned, and the number of seeds per hole can be controlled, which can meet the scientific growth space ratio to the greatest extent, and improve the environment and action time of agricultural machinery, thereby increasing the utilization rate. Moreover, after sowing, the seeds are sandwiched between the two films, which effectively avoids the influence of rats and birds before seedlings and the influence of mixed rice. The seed film bottom film can prevent the growth of weeds, and minimize the adverse effects of biological herbicides on crops and field land.

[0003] Seed film usually needs to be produced with special seeding equipment. Before film coating, the seeds need to be evenly placed on the film layer, then the film layers are pressed together, and finally the seeds are sandwiched between the two films. Currently, there are relatively few equipments specially used for seed film production, and the existing film coating machines are basically used in other product fields.

[0004] The patent with publication number CN103129078A discloses a double-sided laminating machine. This technical solution adopts a pressure roller, a winding shaft, a material plate and other components to cooperate in laminating.

DETAILED DESCRIPTION

[0036] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0037] Example

[0038] like Figure 1-2 As shown, this embodiment provides an automated seed film production device, which uses a PLC system for centralized control. This embodiment uses Mitsubishi's FX2N PLC.

[0039] The automatic seed film production equipment specifically comprises a conveying platform 1, a die mechanism 2 fixed to the conveying platform 1, a seed suction and seed placement mechanism 3, and a glue coating mechanism 4. Figure 3 As shown, the conveyor 1 is provided with a feed shaft 11 for providing the lower film material 6 and a conveyor belt 12 for conveying the lower film material 6. The conveyor belt 12 is arranged horizontally, and the feed shaft 11 is close to the starting end of the conveyor belt 12. At the same time, the conveyor 1 is also provided with a reel 13, which is close to the end of the conveyor belt 12 and is used to reel in the film-coated seed film material. The reel 13 is driven by a motor alone, and the reeling speed is synchronized with the running speed of the conveyor belt 12. The conveyor 1 uses an AC motor as a power source, and drives the reel of the conveyor belt 12 to rotate through a gear set, so that the conveyor belt 12 is transported.

[0040] Generally, the seed film is composed of four parts: a lower film material 6, seeds, a special adhesive, and an upper film material 5. The function of the lower film material 6 is not only to carry seeds according to the specified spacing between rows and plants, but also to play a weeding role. The function of the upper film material 5 is to protect the seeds, prevent them from falling off during transportation, and reduce the influence of external factors during seed development. The two layers of film materials have different requirements. The upper film material 5 is required to have low strength and rot quickly to avoid affecting seed germination. The lower film material 6 is required to have good strength and not rot too quickly to prevent the growth of weeds. Since the lower film material 6 is not easy to rot, it will affect the germination and rooting of seeds. Therefore, it is necessary to punch out dense small holes in a certain area at the planting position to facilitate seed germination and rooting. Special adhesives are usually mixed with various nutrients and pesticides required for seed growth and development, providing protection for seeds and seedlings before tillering.

[0041] Specifically, Figure 4-6 As shown, the punching die mechanism 2 includes a movable die set 21 and a fixed die set 22. Among them, the fixed die set 22 is horizontally fixed to the conveying platform 1, and the movable die set 21 is arranged directly above the fixed die set 22, and reciprocates in the vertical direction, and cooperates with the fixed die set 22 to punch holes in the lower film material 6. In this embodiment, the movable die set 21 includes a movable die support plate 211, a driving member 212, a pressing plate 213 and four punching punches 214, and the driving member 212 is a cylinder, which is centrally controlled by a PLC. The punching punch 214 is arranged on the bottom surface of the pressing plate 213 and arranged in a straight line. The movable die support plate 211 is fixed to the conveying platform 1 and connected to the top surface of the pressing plate 213 through the driving member 212. The driving member 212 drives the pressing plate 213 to reciprocate in the vertical direction. In addition, the movable die support plate 211 is provided with a guide column 2111, which is symmetrically arranged and vertically penetrates the pressing plate 213 to guide the movement of the pressing plate 213. Generally, a sensor for detecting whether the pressing plate 213 has moved into place is also provided on the movable mold supporting plate 211, and the sensor is connected to the PLC.

[0042] In addition, the fixed die group 22 includes a fixed die support plate 221 and four punching dies 222. The fixed die support plate 221 is fixed to the conveying platform 1. The punching dies 222 are arranged on the top surface of the fixed die support plate 221 and correspond to the positions of the punching convex die 214. Specifically, the punching convex die 214 is vertically provided with a plurality of punching needles 2141, and the punching convex die 222 is correspondingly provided with a plurality of hole positions 2221. The hole positions 2221 match the punching needles 2141, and the lower film material 6 is punched to punch out dense small holes in a certain area, and then the seeds are placed in the area. These small holes are mainly convenient for the seeds to germinate and take root. Further, the die mechanism 2 also includes a micro fan 23 and a recycling box 24. The recycling box 24 is arranged adjacent to the fixed die group 22. The micro fan 23 is arranged on the fixed die support plate 221 to blow the waste retained by the punching convex die 222 into the recycling box 24.

[0043] The lower film material 6 is pulled out from the feed shaft 11, passes between the punching punch 214 and the punching die 222, and is placed on the conveyor belt 12 for transportation. The driving member 212 is controlled by the PLC to drive the pressure plate 213, and the punching punch 214 moves vertically downward. The punch needle 2141 breaks through the lower film material 6 and cooperates with the hole position 2221 on the punching die 222 to complete the punching process. The waste generated is blown into the recovery box 24 by the micro fan 23.

[0044] Further, if Figure 7 As shown, the seed suction and release mechanism 3 includes a tray 31 for holding seeds and four suction heads 32 for sucking and releasing seeds, each suction head 32 is connected to an air source, which is an air pump. It also includes a tray 31 connecting frame 33 and a suction head 32 fixing frame 34 arranged adjacent to each other, the tray 31 is connected and fixed to the tray 31 connecting frame 33, and each suction head 32 is evenly fixed to the suction head 32 fixing frame 34. Specifically, in this embodiment, the tray 31 connecting frame 33 is L-shaped as a whole, and the suction head 32 fixing frame 34 is T-shaped as a whole.

[0045] Among them, Figure 8-9 As shown, the tray 31 is in a long strip shape and is spaced apart by four seed grids 311. At the same time, the suction heads 32 are evenly arranged in a straight line on the suction head 32 fixing frame 34. The straight line where the suction heads 32 are located is parallel to the long direction of the tray 31, and one suction head 32 corresponds to one seed grid 311. Vibration motors 312 for shaking the seeds evenly are also provided at both ends of the tray 31. The vibration motor 312 vibrates continuously during operation to shake the seeds evenly.

[0046] In addition, the tray 31 connecting frame 33 is connected to a horizontal driving assembly 35 , and the suction head 32 fixing frame 34 is connected to a vertical driving assembly 36 .

[0047] Specifically, Fig.10As shown, the horizontal driving assembly 35 includes a horizontal base 351 and a horizontal driving member 352 disposed on the horizontal base 351. The horizontal base 351 is fixedly disposed, and the horizontal driving member 352 is connected to one end of the tray 31 connecting frame 33. In this embodiment, the horizontal driving member 352 includes a horizontal driving motor 3521, a horizontal transmission assembly 3522, a horizontal guide rail 3523 and a horizontal slider 3524. The horizontal driving motor 3521 and the horizontal guide rail 3523 are fixed to the horizontal base 351. The horizontal slider 3524 is slidably connected to the horizontal guide rail 3523, and the horizontal slider 3524 is connected to one L-shaped end of the tray 31 connecting frame 33. At the same time, the horizontal transmission assembly 3522 adopts a gear rack assembly. The output end of the horizontal driving motor 3521 rotates the gear, and the engagement between the gear and the rack drags the horizontal slider 3524, thereby smoothly driving the tray 31 connecting frame 33 to move in the horizontal direction.

[0048] Similarly, if Fig.11 As shown, the vertical drive assembly 36 includes a vertical base 361 and a vertical drive member 362 disposed on the vertical base 361. The vertical base 361 is fixedly disposed, and the vertical drive member 362 is connected to one end of the tray 31 connecting frame 33. In this embodiment, the vertical drive member 362 includes a vertical drive motor 3621, a vertical transmission assembly 3622, a vertical guide rail 3623 and a vertical slider 3624. The vertical drive motor 3621 and the vertical guide rail 3623 are fixed to the vertical base 361, and the vertical slider 3624 is slidably connected to the vertical guide rail 3623. At the same time, the vertical slider 3624 is connected to one end of the T-shaped edge of the suction head 32 fixing frame 34. At the same time, the vertical transmission assembly 3622 adopts a gear rack assembly. The output end of the vertical drive motor 3621 rotates the gear, and the engagement between the gear and the rack drags the vertical slider 3624, thereby smoothly driving the suction head 32 fixing frame 34 to move in the vertical direction, thereby changing the height of the suction head 32.

[0049] Specifically, in this embodiment, the air source, the horizontal drive motor 3521, the vertical drive motor 3621, and the vibration motor 312 are all centrally controlled by the PLC system. Alternatively, the horizontal drive member 352 and the vertical drive member 362 may also be a cylinder, one end of which is fixed to the horizontal base 351 or the vertical base 361, and the other end is connected to the tray 31 connecting frame 33 or the suction head 32 fixing frame 34, and the tray 31 connecting frame 33 and the suction head 32 fixing frame 34 are pushed back and forth by the cylinder or the oil cylinder to move horizontally or vertically.

[0050] The original state of the seed suction and seed placement mechanism 3 is generally that the suction head 32 and the tray 31 are adjacent and located at the same horizontal height. One suction head 32 corresponds to a punching punch 214 and a punching die 222, ensuring that the corresponding suction head 32 is responsible for placing seeds in a single punching area. Before operation, the crop seeds are placed as evenly as possible in various sub-grids 311. Then, the power is turned on and the PLC system is centrally controlled. The vibration motor 312 vibrates continuously to shake the seeds on the tray 31 evenly. First, the vertical drive motor 3621 runs, and the vertical slider 3624 is dragged by the vertical transmission component 3622, thereby driving the suction head 32 fixing frame 34 to move vertically upward, so that the height of each suction head 32 is higher than the height of the tray 31. Then, the horizontal drive motor 3521 runs, and the horizontal slider 3524 is dragged by the horizontal transmission component 3522, thereby driving the tray 31 connecting frame 33 to move horizontally to the bottom of the suction head 32, so that various sub-grids 311 are located directly below the suction head 32. Next, the vertical drive motor 3621 runs in the reverse direction, driving the suction head 32 to move vertically downward, and at the same time, the air source starts to provide negative pressure to each suction head 32, so that the suction head 32 can smoothly absorb the seeds. After the absorption is completed, the vertical drive motor 3621 drives the suction head 32 to move vertically upward again. At this time, the horizontal drive motor 3521 runs in the reverse direction, so that the tray 31 connecting frame 33 drives the tray 31 to return horizontally. Finally, the suction head 32 is moved vertically downward again, and the air source is released or positive pressure is provided, so that the suction head 32 completes the seed placement. Furthermore, the motor rotation parameters can be changed through the PLC system, and the movement distance of the tray 31 and the suction head 32 in the horizontal and vertical directions can be adjusted, so as to flexibly adjust the seed placement plan.

[0051] Further, if Figure 12-13 As shown, the glue coating mechanism 4 includes a press roller 41, a rotating glue coating member 42 and a winding shaft 44 for feeding the upper film material 5. During operation, the press roller 41 abuts against the surface of the conveyor belt 12, pressing the lower film material 6 against the surface of the conveyor belt 12, and the lower film material 6 moves integrally with the conveyor belt 12, and the press roller 41 rotates with the transmission of the conveyor belt 12 and the lower film material 6. The winding shaft 44 is arranged parallel to the press roller 41. Generally, the upper film material 5 can be a strip film material, and the lower film material 6 is bonded separately, so that the size error of the film can be reduced.

[0052] The rotating glue coating member 42 abuts against the surface of the nip roller 41, and the axis lines of the two are parallel. In this embodiment, the axis lines of the two are located on the same vertical plane. In addition, the rotating glue coating member 42 is kept spaced from the conveyor belt 12 to prevent the glue coating from directly contacting the conveyor belt 12.

[0053] Specifically, the surface of the nip roller 41 is surrounded by a rubber layer 46, and the rubber layer 46 is elastically pressed against the conveyor belt 12. By utilizing the elastic properties of the rubber layer 46, the nip roller 41 can exert a certain pressure on the conveyor belt 12 to make the coating smooth and tightly pressed, and at the same time increase the friction of the nip roller 41, so as to facilitate the transmission of the upper film material 5.

[0054] The glue coating mechanism 4 also includes a glue supply box 43 for storing adhesive. The glue supply box 43 is a funnel-shaped structure. A strip-shaped glue outlet 48 is left at the bottom of the glue supply box 43. The glue outlet 48 is closely attached to the surface of the rotating glue coating member 42. The adhesive flows out from the glue outlet 48 to the rotating glue coating member 42. In addition, the rotating glue coating member 42 is hingedly fixed to the glue supply box 43. The glue supply box 43 is provided with side wings. The rotating glue coating member 42 is rotatably mounted on the side wings of the glue supply box 43. Fig.14 shown.

[0055] The rotating glue coating member 42 of this embodiment is a glue coating roller, and a sponge layer 47 surrounds the surface of the glue coating roller. The glue coating roller absorbs the adhesive by the outer surrounding sponge layer 47, so that the adhesive is evenly spread on the sponge layer 47. This embodiment uses an aqueous solution type adhesive, and various nutrients and pesticides required for seed growth and development are mixed into the adhesive to provide protection for the seeds and the seedlings before tillering.

[0056] This embodiment also includes a secondary shaft 45 for winding the upper film material 5. The secondary shaft 45 is arranged parallel to the pressure roller 41. The winding shaft 44 is arranged at a height higher than the pressure roller 41. The secondary shaft 45 is mainly used to guide the direction of the upper film material 5.

[0057] Furthermore, the winding shaft 44, the auxiliary shaft 45, the pressure roller 41, and the glue supply box 43 are all fixed on the conveying platform 1 through a bracket. According to production needs, multiple groups of glue supply boxes 43 can be set up, and each glue supply box 43 is independently installed with a rotating glue coating member 42, and at the same time cooperates with its corresponding pressure roller 41. Each pressure roller 41 can be kept on the same axis or be staggered.

[0058] This embodiment is provided with four groups of glue supply boxes 43, and each glue supply box 43 and rotating glue coating member 42 individually corresponds to the punching punch 214, the punching die 222, and the suction head 32 on the same path, and is arranged in the form of an assembly line.

[0059] The specific implementation process is as follows: before the glue coating and film pressing, the seeds are first placed stably on the lower film material 6, and the lower film material 6 is conveyed by the conveyor belt 12. At the same time, the winding shaft 44 provides the upper film material 5, and the upper film material 5 is wound and guided by the secondary shaft 45 and then rolled into the clamping roller 41 and the rotating glue coating member 42. One side of the upper film material 5 is tightly attached to and rolled on the pressing roller 41, and the other side is tightly attached to the rotating glue coating member 42. The adhesive is stored in the glue supply box 43, and the adhesive flows out through the glue outlet 48 to the sponge layer 47 on the outer layer of the rotating glue coating member 42.

[0060] As shown in 13, the lower film material 6 is driven to the right along with the conveyor belt 12, and the conveyor belt 12 drives the nip roller 41 to rotate counterclockwise. Since the nip roller 41 is wound with the upper film material 5, the nip roller 41 pulls the upper film material 5 to drive. Similarly, the upper film material 5 drives the rotating glue coating member 42 to rotate clockwise, and the rotating glue coating member 42 evenly adheres the adhesive to the surface of the upper film material 5. The glue coating mechanism 4 uses the conveyor belt 12 to provide power, and the transmission is step-by-step, and there is no need to set up a drive motor separately. When the upper film material 5 rotates with the nip roller 41 until it contacts the lower film material 6, it is bonded, and the nip roller 41 presses the upper film material 5 and the lower film material 6 to complete the seed coating. The film material that has completed the seed coating continues to be conveyed along the conveyor belt 12 to proceed to the next winding process.

[0061] Furthermore, the conveying platform 1 is also provided with a pressure roller 14, which abuts against the surface of the conveying belt 12 and is arranged perpendicular to the conveying direction. The pressure roller 14 is arranged between the die mechanism 2 and the seed suction and release mechanism 3, and between the glue coating mechanism 4 and the winding shaft 13.

[0062] Before starting the machine, first install the lower film material 6 roll onto the feed shaft 11, pull out the lower film material 6, pass through the die mechanism 2, and place it on the surface of the conveyor belt 12. At the same time, it is pressed by the pressure roller 41 and the edge pressure roller 14, and is wound on the winding shaft 13. In addition, install the upper film material 5 roll onto the winding shaft 44, pull out the upper film material 5, wind it around the secondary shaft 45, and roll it between the pressure roller 41 and the rotating glue coating member 42, and then roll it on the pressure roller 41.

[0063] Place the crop seeds as evenly as possible in various sub-grids 311, place the suction head 32 and tray 31 in the initial position, and the PLC system performs centralized control. After starting the machine, you can select the PLC normal operation mode or adjustment mode according to actual needs. Starting the normal mode means starting production immediately. Starting the adjustment mode can adjust the feeding length, the position of the tray 31 and the suction head, control the punching and seed placement positions, and exit the adjustment mode after the adjustment is completed.

[0064] Each mechanism operates periodically under the control of PLC. The conveyor belt 12 and the coil shaft 44 rotate synchronously. After the initialization adjustment is completed, the punch mechanism 2 punches the lower film material 6. The punch movement is achieved by pneumatic control. The cylinder has two upper and lower air vents. When the air pressure enters from the upper air vent, the punching punch 214 descends; when the air pressure enters from the lower air vent, the punching punch 214 rises; the control of the air circuit is achieved by PLC controlling a three-position five-way air pressure valve.

[0065] The seed suction and seed placement mechanism 3 places seeds in the perforated area, and achieves seed suction and seed placement by controlling the air pump air circuit. The components of the air circuit include: a two-position three-way air pressure valve and a negative pressure adapter. When the solenoid valve is powered on, the air pressure pump air circuit is connected, and the high-pressure gas flows through the negative pressure adapter to generate negative pressure in the suction head 32 to achieve seed suction; when the power is off, the air pressure pump air circuit is blocked, and the suction head 32 is connected to the atmospheric pressure. Under the action of gravity, the seeds fall naturally to achieve seed placement. This seed placement method is stable and can basically accurately fall on the perforated area. The placing process is as follows: 1) the punching punch 214 rises and the suction head 32 rises; 2) the seed grid 311 of the tray 31 moves horizontally to just below the suction head 32; 3) the suction head 32 descends to absorb the seeds; 4) the suction head 32 rises; 5) the seed grid 311 of the tray 31 returns horizontally; 6) the conveyor belt 12 transports the lower film material 6, and the suction head 32 descends; 7) wait for the lower film material 6 to arrive at the positioning; 8) the suction head 32 releases the seeds; 9) return to the first step.

[0066] After the seed is placed, the lower film material 6 is transported to the glue coating mechanism 4, and the upper film material 5 coated with adhesive and the lower film material 6 are pressed by the material roller 41.

[0067] The lower film material 6 is driven together with the conveyor belt 12. Due to the effect of friction, the conveyor belt 12 drives the nip roller 41 to rotate counterclockwise through the lower film material 6. Since the nip roller 41 is wound with the upper film material 5, the nip roller 41 pulls the upper film material 5 to drive. Similarly, the upper film material 5 drives the rotating glue coating member 42 to rotate clockwise, and at the same time, the rotating glue coating member 42 evenly adheres the adhesive to the surface of the upper film material 5. When the upper film material 5 rotates with the nip roller 41 until it contacts the lower film material 6, it is bonded. The nip roller 41 bonds and presses the upper film material 5 and the lower film material 6, thereby completing the seed coating. In this process, the conveyor belt 12 is continuously driven forward. Finally, the seed film after coating is subjected to the winding tension of the winding shaft 13 and is wound.

[0068] The row spacing can be precisely controlled by PLC control, and the plant spacing can be precisely controlled by adjusting the positions of the seed suction and seed release mechanism 3 and the punch mechanism 2. The matrix hole array allows the seeds to take root in the soil smoothly after germination.

[0069] The storability of seed film is greatly improved, and the seed film can be processed in advance, which increases the working time without affecting the farming season, and a film-laying machine with only simple rotary motion can be used instead of a complex rice transplanter.
