Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to an automatic adhesive seed-adhesive film-laying device and its working method. Background Technology

[0002] Currently, in agriculture or crop cultivation, such as rice cultivation, the traditional method of artificially cultivating rice seedlings is widely used. Once the seedlings have grown sufficiently tall, they are transported to the paddy fields for manual transplanting. This traditional method suffers from high labor intensity, large capital investment, long production cycles, and low planting efficiency. Furthermore, due to differences in individual planting skills, uneven row and seed spacing leads to low seedling emergence rates and ultimately lower rice yields. This situation not only significantly increases farmers' physical labor but also directly impacts rice production, thereby directly affecting farmers' income.

[0003] Therefore, how to reduce the intensity of manual labor, increase the seedling emergence rate, and improve planting efficiency in the breeding and planting process is a technical problem that urgently needs to be solved.

[0004] While there are existing technologies that can eliminate the need for seeding, the existing precision seeding machines for rice mulch are only applicable to rice seeding operations, which has significant limitations and makes it difficult to achieve universal design and operation. Moreover, during the winding process, the winding of the film is restricted and cannot meet the maximum film winding design. The length of the film that can be wound by the film release roller is limited, making the operation complex and costly. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of existing mulch film seed attaching machines, which cannot achieve universal design, can only be designed differently for different seeds such as rice, have high costs and complicated operation, and provide a universal automatic adhesive seed attaching and film attaching device and its working method that can maximize the film rolling operation.

[0006] The technical solution adopted by this invention to achieve its first inventive objective is: an automatic adhesive application and seed film placement device, comprising:

[0007] The seed film unwinding mechanism is used to achieve adjustable unwinding of biodegradable mulch film.

[0008] The glue injection and supply system includes a glue roller and several adjustable, independently driven glue application devices.

[0009] Several adjustable seed storage and feeding devices are set up one-to-one with the gluing device and are independently controlled;

[0010] A plastic film cutting device is used to cut growth holes in biodegradable plastic film in seed-growing areas; the plastic film cutting device is independently controlled and is equipped with several adjustable cutting blades.

[0011] A seed film winding mechanism is a device for winding up biodegradable mulch film after seeding; the seed film winding mechanism is equipped with a swing mechanism.

[0012] This automatic seed gluing and film-laying equipment is sequentially equipped with a seed film unwinding mechanism, a glue injection and supply system, a seed storage and loading device, a film cutting device, and a seed film winding mechanism. This achieves automated operations from film laying to seed gluing, cutting growth holes, and film winding. To ensure versatility, the seed film unwinding mechanism is adjustable, allowing for adjustments to the unwinding speed to suit different seed gluing requirements. Simultaneously, the glue injection and supply system includes several independently driven adjustable gluing devices. Each device can be controlled independently, either operating alone or in tandem. Therefore, it can be customized to meet varying needs. The position of the gluing device on the seed-adhesive area of ​​the mulch film is adjusted, and the gluing device is activated accordingly, thus achieving controllable gluing operation. Correspondingly, the seed storage and application device is set up one-to-one with the gluing device, also using adjustable independent control. The position of the seed storage and application device can be adjusted, and it can be controlled independently or operated in tandem. The appropriate seed storage and application device can be selected according to the seed-adhesive area. Through independent control of the gluing system and the seed storage and application device, the needs of different seeds for seed adhesion can be met, achieving a universal design for the entire equipment, eliminating the need to design specific seed-adhesive film application equipment for each type of seed. Simultaneously, the mulch film cutting device uses independent control. The rotation speed of the mulch film cutting device can be adjusted according to the winding speed of the biodegradable mulch film, and the cutting blade can be adjusted to cut the seed-adhesive area on the biodegradable mulch film, achieving simultaneous and controllable operation. A swing mechanism is set in the seed film winding mechanism, enabling the seed film winding mechanism to move left and right within a certain range in the axial direction, thereby achieving effective winding of the biodegradable mulch film and maximizing the winding of as much biodegradable mulch film as possible. This automatic gluing and film-laying equipment features a universal design, effectively reducing production costs, maximizing film collection, and improving operational efficiency.

[0013] Preferably, the seed film unwinding mechanism includes a magnetic powder motor and an unwinding roller for adjusting the rotational speed of the seed film unwinding mechanism. The seed film unwinding mechanism uses a magnetic powder motor to adjust the rotational speed, thereby controlling the tightness of the biodegradable mulch film during the unwinding process. The biodegradable mulch film roll is mounted on the unwinding roller, and during use, the biodegradable mulch film is unwound gradually.

[0014] Preferably, the rubber roller moves synchronously and in opposite directions with several independently driven gluing devices; the surface of the rubber roller is provided with several seed-adhesive protrusions; the seed-adhesive protrusions are integrally formed with the rubber roller, or the seed-adhesive protrusions and the rubber roller are separately formed and replaceable, with the seed-adhesive protrusions located in a seed-adhesive protrusion replacement structure with an impeller structure. The rubber roller and the gluing devices are configured to work together to enable the biodegradable mulch film on it to be glued and sown at the seed-adhesive protrusions during the rotation of the rubber roller. To achieve a universal design, the seed-binding protrusions on the rubber roller can be integrated with the roller itself or be a built-in, replaceable, separate design. Specifically, an impeller-type seed-binding protrusion replacement structure is installed inside the rubber roller, with corresponding replacement holes for the required seed-binding protrusions on the roller. The impeller-type seed-binding protrusion replacement structures are distributed along the axial direction of the rubber roller, and each impeller-type seed-binding protrusion replacement structure has a corresponding number of seed-binding protrusions on the circumference of the rubber roller. When performing seed-binding operations for different seeds, only the seed-binding protrusions on the impeller-type seed-binding protrusion replacement structure need to be replaced. In use, the seed-binding protrusions extend from the replacement holes on the rubber roller, protruding on the roller surface, and are used to raise the seed-binding position of the biodegradable mulch film, thereby realizing the gluing and seed-binding operations.

[0015] Preferably, the gluing device has a sliding adjustable structure. The gluing device includes a gluing auxiliary motor, a gluing wheel driven by the gluing auxiliary motor and in rotational contact with the glue roller, and a glue injection box containing glue. The glue injection box contains nutrient glue. The gluing wheel, driven by the gluing auxiliary motor, rotates inside the glue injection box to apply glue. A scraper is provided on the glue injection box, which contacts the gluing wheel to scrape off excess glue. The gluing device is designed to be sliding adjustable, allowing for adjustment based on different seed-adhesive protrusions on the glue roller. During the gluing process, the gluing auxiliary motor drives the gluing wheel to rotate inside the glue injection box, carrying the glue from the box onto the gluing wheel. The glue is then transferred to the biodegradable mulch film by the gluing wheel contacting the seed-adhesive protrusions on the glue roller. To prevent the gluing wheel from carrying excess glue, a scraper is used to remove excess glue from the gluing wheel, achieving effective gluing.

[0016] As another preferred embodiment, the gluing device includes a high-pressure glue cylinder, a high-pressure glue spray head connected to the high-pressure glue cylinder, and a glue control device. The glue control device includes a glue surface control plate with a glue control port. Intermittent glue spraying is achieved through the high-pressure glue cylinder and the high-pressure glue spray head, while the high-pressure glue spray head sprays glue instantaneously. The amount of glue sprayed by the high-pressure glue spray head at one time can be set according to the needs of seed bonding, achieving different thicknesses of glue application, thus realizing adjustable and controllable glue settings. Timed and quantitative glue spraying effectively controls the glue amount and ensures the consistency and uniformity of the glue thickness on the seed bonding surface. It also allows for glue amount control and adjustment settings for different seeds, resulting in good seed bonding effect and is economical and practical.

[0017] Preferably, the seed storage and loading device is a slidably adjustable structure, comprising a vibrator and a seed storage box that vibrates due to the vibrator. The seed storage box has a feeding conveyor channel and a conveying channel. The conveying channel works in conjunction with the biodegradable mulch film with adhesive on the seed-adhesive protrusions on the rubber roller to achieve seed adhesion. The slidably adjustable structure allows for the sliding adjustment of the position of each set of seed storage and loading devices. Several sets of seed storage and loading devices are provided, each set including an independently controlled vibrator and a seed storage box that vibrates due to the vibrator. The vibration of the seed storage box orderly vibrates the seeds inside the box to the feeding conveyor channel, and then into the conveying channel to adhere to the adhesive on the biodegradable mulch film, thus achieving seed adhesion. During the seed adhesion process, since the size of the adhesion area is preset, a limited number of seeds are adhered within the adhesion area, ensuring uniform and controllable seed adhesion. Each seed storage and sowing device can be controlled independently or operated in coordination, enabling adjustable and controllable sowing operations.

[0018] As another preferred embodiment, the seed storage and loading device includes a vibrator, a vibration motor, a seed storage box, and a turntable disposed inside the seed storage box. The seed loading and loading operation is achieved by the rotation and vibration of the turntable. The turntable has a seed screening function to ensure that the seeds picked up are all high-quality seeds, while unqualified seeds will vibrate back to the seed storage box during the vibration process.

[0019] Preferably, the mulch film cutting device includes a rotating shaft driven by a drive motor and several adjustable cutting blades slidably mounted on the rotating shaft. Each adjustable cutting blade includes a blade holder wheel and cutting blades mounted on the blade holder wheel. Preferably, the blade holder wheel has an inner groove, and a pair of replaceable adjustable cutting blades are symmetrically arranged inside the inner groove. The distance between the cutting blades is greater than the width of the seed-coated area on the biodegradable mulch film. The mulch film cutting device is driven by an independent motor, and the several blade holder wheels are slidably and adjustable on the rotating shaft. The distance between the blade holder wheels is adjustable, thus meeting the cutting requirements for mulch films with different seeds. The inner groove on the blade holder wheel allows for the replacement of different cutting blades for different seed-coated mulch films, thus meeting the universal design requirements of the mulch film cutting device.

[0020] Preferably, the seed film winding mechanism includes a seed-bonded film roll driven to rotate by a servo motor. The seed-bonded film roll is mounted on the oscillating mechanism and oscillates with it. The seed film winding mechanism is designed to wind up the biodegradable mulch film with seeds attached. The servo motor adjusts the rotation speed of the winding mechanism to control the tightness of the biodegradable mulch film during winding. The oscillating mechanism allows for the oscillating operation of the winding roller, ensuring that as much biodegradable mulch film as possible is wound onto the seed-bonded film roll, significantly reducing the number of roll replacements and improving operational efficiency.

[0021] Preferably, the oscillating mechanism includes an oscillating motor and an oscillating assembly driven by the oscillating motor. Preferably, the oscillating assembly includes a fixed plate with a slide rail, a movable plate slidably disposed on the fixed plate, and a connecting shaft connecting the two movable plates and driving the movable plate to move. The above structure of the oscillating mechanism enables the oscillating motor to drive the film-receiving roller to reciprocate axially, achieving maximum film-receiving operation.

[0022] Preferably, the system also includes a transmission system, which comprises a main control motor, transmission gears, and a transmission chain.

[0023] Preferably, the system also includes a film-spreading roller, a tension roller, an upper tension roller, a film-cutting and spreading roller, and a film-retracting tension roller arranged on the unwinding and rewinding path. The biodegradable mulch film, after being unwound from the seed film unwinding mechanism, sequentially passes through the film-spreading roller, tension roller, adhesive roller, upper tension roller, film-cutting and spreading roller, and film-retracting tension roller before being wound up by the seed film rewinding mechanism. The transmission gears are respectively mounted on the tension roller, adhesive roller, upper tension roller, and film-cutting and spreading roller. This structure is designed to achieve coordinated operation of the entire process of film unwinding, adhesive application, seed bonding, cutting, and film rewinding.

[0024] The technical solution adopted by this invention to achieve its second objective is: a working method of an automatic adhesive seed-adhesive film-laying device, comprising the following steps:

[0025] Step 1: Turn on the main control motor to drive the transmission chain for linkage;

[0026] Step 2: Start the magnetic powder motor. The magnetic powder motor drives the film feeding roller to rotate and feed the film synchronously.

[0027] Step 3: Apply the nutrient adhesive to the raised areas of the biodegradable mulch film using the adhesive application device;

[0028] Step 4: Pour the seeds into the vibrator seed storage box, turn on the vibrator seed storage box switch, and the seeds in the vibrator seed storage box will vibrate at high frequency. The biodegradable mulch film with glue on the raised areas will pick up the vibrating seeds as the glue roller rotates.

[0029] Step 5: Turn on the switch of the mulch film cutting device. The drive motor drives the blade holder wheel with cutting blades on the rotating shaft to rotate. The cutting blades cut growth holes on both sides of the area where the seeds are attached to the biodegradable mulch film.

[0030] Step 6: Start the servo motor and the swing motor. The servo motor drives the film-taking roller to rotate, while the swing motor drives the swing mechanism shaft to swing back and forth along the axis of the film-taking roller, thereby rotating and taking in the biodegradable mulch film with seeds on the seed-forming film roll.

[0031] The above-described working method automates the entire process of gluing and bonding seeds, and each step is adjustable and controllable with good coordination. It can meet the needs of gluing and film-coating different seeds, and is efficient and low-cost.

[0032] The beneficial effects of this invention are: the automatic seed gluing and film-laying device achieves a universal design, meeting the needs of seed gluing and film-laying for different seeds. Any plant requiring breeding operations can undergo seed gluing and film-laying operations using this device, greatly improving its practicality and versatility. Furthermore, it maximizes film-laying efficiency, reducing the frequency of changing the seed-forming film-laying cylinder and improving work efficiency. Attached Figure Description

[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0057] Example 1:

[0058] exist Figure 1 , Figure 2 , Figure 3 In the illustrated embodiment, an automatic adhesive seed-laying film device is provided. This device is used to adhesively attach seeds that need to be cultivated onto a biodegradable film 2 to facilitate seed germination.

[0059] An automatic seed-attaching and film-laying device includes a frame 1, on which are mounted a transmission system 100 for power transmission, a seed film unwinding mechanism 200 for adjustable film-laying operation of biodegradable mulch film 2, an adhesive injection and supply system 300 for adhesive application, several adjustable seed storage and feeding devices 400 with independent control and corresponding to the adhesive application devices for feeding seeds, a mulch film cutting device 500 for cutting growth holes in the biodegradable mulch film 2 with seeds attached, and a seed film winding mechanism 600 for winding up the retractable mulch film with seeds attached.

[0060] The mulch film cutting device 500 is independently controlled and includes several adjustable cutting blades. The seed film winding mechanism 600 includes a swing mechanism.

[0061] The glue supply system is equipped with a glue roller 30 and several independent glue application devices 31; the glue roller and several independent drive glue application devices move synchronously in opposite directions.

[0062] The seed film unwinding mechanism 200 and the glue injection and supply system 300 are driven synchronously by the transmission system 100. The mulch film cutting device 500 is driven by an independent drive device, and its rotation speed is matched with the rotation speed of the biodegradable mulch film seed-adhesive area.

[0063] The transmission system 100 drives the seed film unwinding mechanism to perform the film unwinding operation, and at the same time drives the glue injection system to perform the glue application operation.

[0064] The transmission system 100 includes a master motor 10, transmission gears, and a transmission chain 11. The master motor 10 provides the main power. An output gear 13 is mounted on the output shaft 12 of the master motor 10. The power of the master motor is transmitted through the output gear to drive the transmission chain 11.

[0065] It also includes a film spreading roller 3, a tensioning roller 4, an upper tensioning roller 5, a film cutting and spreading roller 6, and a film taking-up tensioning roller 7 arranged on the unwinding and rewinding path. The biodegradable mulch film 2 is unwound from the seed film unwinding mechanism 200 and passes sequentially through the film spreading roller 3, the tensioning roller 4, the rubber roller 30, the upper tensioning roller 5, the film cutting and spreading roller 6, and the film taking-up tensioning roller 7 to the seed film rewinding mechanism 600 for winding.

[0066] The transmission gears are respectively mounted on the tension roller 4, the rubber roller 30, the upper tension roller 5, and the film cutting and spreading roller 6.

[0067] In this embodiment, a film spreading roller 3 is provided on the path from the seed film unwinding mechanism 200 to the glue injection system 300 for tensioning and conveying the biodegradable mulch film 2 unwound from the seed film unwinding mechanism 200. A tensioning roller 4 is provided between the film spreading roller 3 and the glue supply system 300. A tensioning transmission gear 401 is provided on the tensioning roller 4. The transmission chain 11 meshes with the tensioning transmission gear 401. The biodegradable mulch film 2 is wound around the glue roller 30 of the glue supply system after passing through the tensioning roller 4. A glue roller transmission gear 301 is provided on the glue roller 30. The biodegradable mulch film 2 with seeds attached is conveyed from the glue roller 30 and is conveyed to the mulch film cutting device 500 through the upper tensioning roller 5 provided above the glue roller. An upper tensioning roller transmission gear 501 is provided on the upper tensioning roller 5. Corresponding to the mulch film cutting device 500, a film spreading and cutting roller 6 is provided. A film spreading and cutting roller transmission gear 601 is provided on the film spreading and cutting roller 6. The biodegradable mulch film conveyed from the film spreading and cutting roller 6 is tensioned by a film taking-up tensioning roller 7 and then conveyed to the seed film taking-up mechanism 600 for taking-up.

[0068] The specific transmission process of the transmission system 100 is as follows: the transmission chain 11 is sequentially wound around the output gear 13, the tension transmission gear 401, the rubber roller transmission gear 301, and the film cutting and spreading roller transmission gear 601. The main control motor 10 drives the output gear 13 to rotate, which in turn drives the tension roller 4 to rotate through the transmission chain 11, and at the same time drives the rubber roller 30 to rotate. The tension roller 4 and the rubber roller 30 rotate in opposite directions, thereby realizing the gluing and seed bonding operations. During the rotation of the rubber roller 30, the upper tension roller 5 rotates together with the transmission chain 11, thereby realizing the tension of the biodegradable mulch film. At the same time, the film cutting and spreading roller 6 rotates together with the transmission chain 11 to realize the cutting of the process holes of the biodegradable mulch film.

[0069] like Figure 3 As shown, the seed film unwinding mechanism 200 includes an unwinding roller 20, an unwinding shaft 21, and an unwinding support 22. The unwinding support 22 is mounted on the frame 1, and the unwinding shaft 21 is rotatably mounted on the unwinding support 22. The unwinding roller 20 is mounted on the unwinding shaft 21. To adjust the rotational speed of the seed film unwinding mechanism, a magnetic powder motor 23 is also included in the seed film unwinding mechanism 200. The magnetic powder motor 23 is mounted on the frame 1 and connected to the unwinding shaft 21, and can adjust the rotational speed of the seed film unwinding mechanism, thereby controlling the tightness of the biodegradable mulch film during the unwinding process. The magnetic powder motor can adjust the rotational speed of the seed film unwinding mechanism, thereby controlling the tightness of the biodegradable mulch film during the unwinding process.

[0070] like Figure 4As shown, the glue injection and supply system 300 is fixed on the frame 1. The glue injection and supply system 300 includes a glue roller 30 and several glue application devices 31. The glue roller 30 is rotatably connected to the frame 1 and driven to rotate by the transmission system 100. Several seed-adhesive protrusions 38 are provided on the main body of the glue roller 30. The seed-adhesive protrusions on the roller surface are integrally set with the glue roller, requiring the entire glue roller to be replaced when different seeds are used. Specifically, the seed-adhesive protrusions 38 on the glue roller are set according to the longitudinal and transverse spacing of the breeding. In this embodiment, eight rings of seed-adhesive protrusions are arranged side by side along the axial direction on the roller surface of the glue roller, with the seed-adhesive protrusions in each ring spaced apart. The surface area of ​​each seed-adhesive protrusion on the surface of the glue roller is approximately 4 cm². 4cm. Approximately 7 seeds adhere to the seed-adhesive protrusion area. The glue-dispensing system 300 moves synchronously with the transmission system.

[0071] The biodegradable mulch film 2 is wound around the rubber roller 30. The rubber roller is provided with seed-adhesive protrusions with raised block structures at every 40cm interval. When the transmission system is started, the film-laying roller realizes the film-laying operation. At the same time, the rubber roller rotates, so that the biodegradable mulch film 2 and the rubber roller move relative to each other. At the same time, the seed-adhesive protrusions on the rubber roller make the biodegradable mulch film protrude from the roller surface of the rubber roller to facilitate the gluing operation.

[0072] like Figure 5 As shown, in this embodiment, the gluing device 31 has a sliding adjustable structure. Each gluing device 31 is respectively mounted on a gluing slide plate 302, which is slidably mounted on a gluing device slide rail 303, which is fixed to the frame 1. The position of the gluing device relative to the seed-adhesive protrusion on the glue roller surface is adjusted by adjusting the position of the slide plate.

[0073] There are eight sets of gluing devices 31, which are arranged in a linear fashion. Each set of gluing devices corresponds to a ring of adhesive protrusions 38 on the glue roller.

[0074] Each glue application device 31 includes a glue application roller 32, a glue injection box 33, a glue scraper 34, a meshing gear set, and a glue application auxiliary motor 39. The glue injection box 33 is fixed on the frame 1 and is located on the side and below the glue roller 30. Figure 6 As shown, the meshing gear assembly includes a motor gear 35 and a glue shaft gear 36. The glue-applying roller 32 is rotatably mounted in the glue injection box 33 via a glue-applying shaft 37. The glue-applying roller is positioned directly opposite the seed-adhesive protrusions on the glue roller and contacts the biodegradable mulch film where the seed-adhesive protrusions are located during rotation, thus realizing the glue-applying operation of the biodegradable mulch film. The glue shaft gear 36 is mounted on the glue-applying shaft 37, and the motor gear 35 is mounted on the output shaft of the glue-applying auxiliary motor 39. The glue-applying auxiliary motor 39 drives the upper meshing gear assembly to move, thereby driving the glue-applying roller to rotate. Figure 7As shown, during operation, nutrient-rich adhesive 8 for seed bonding is injected into the glue injection box. The glue application auxiliary motor is then started, driving the glue application wheel to rotate. During rotation, the glue application wheel 32 carries and applies the nutrient-rich adhesive inside the glue injection box 33. This adhesive promotes crop growth and decomposes upon contact with water. The glue-coated wheel evenly applies the adhesive to the raised areas of the biodegradable mulch film 2 during rotation, completing the glue application process. To prevent excess adhesive from being carried out, a scraper is provided on the glue injection box corresponding to the glue application wheel.

[0075] like Figure 8 As shown, the seed storage and loading device has a sliding and adjustable structure. In this embodiment, multiple sets of seed storage and loading devices 400 are provided, each set being mounted on a seed storage device slide plate 45. The seed storage device slide plate 45 is slidably mounted on a seed storage device slide rail 46. The multiple sets of seed storage and loading devices 400 are fixed in a linear array on the frame 1, and the seed storage and loading devices 400 are positioned directly below the rubber roller 30. During the rotation of the biodegradable mulch film driven by the rubber roller, the biodegradable mulch film with seeds adhered to it will adhere to the seeds conveyed in the seed storage and loading device, and a set number of seeds will be adhered to the biodegradable mulch film, which will then be rolled up along with the biodegradable mulch film.

[0076] In this embodiment, eight sets of seed storage and loading devices 400 are provided, each corresponding to the location of the seed-adhesive protrusions on the rubber roller. Each set of seed storage and loading devices 400 is a vibratory seed storage and loading device, mainly including a vibrator 40, a vibratory motor 41, a seed storage box 42, and a feeding channel 43. The vibrator is connected to the vibratory motor, the seed storage box is mounted on the vibrator, and the feeding channel 43 is mounted on the seed storage box 42. The vibrator generates vibration through the vibratory motor, which in turn causes the seed storage box to vibrate. The vibration of the seed storage box vibrates the seeds 9 to the feeding channel, and the feeding channel delivers the seeds 9 to the position where they contact the rubber roller.

[0077] like Figure 9 As shown, the seed storage box 42 is provided with a feeding conveying channel 44, and the feeding channel 43 is connected and fixed to the seed storage box 42 and communicates with the feeding conveying channel 44. A vibrating cam is installed on the rotating shaft of the vibrating motor 41. The vibrating cam has an eccentric structure. When the high-frequency vibrating motor 41 rotates, it drives the eccentric vibrating cam to rotate at high speed. The vibrating cam drives the seed storage box 42 to vibrate up and down, generating high-frequency micro-amplitude reciprocating vibration. When the seed storage box vibrates, it shakes the seeds in the seed storage box into the feeding conveying channel, and then vibrates them into the feeding channel 43 for sorting. During the rotation of the rubber roller, the seeds 9 adhere to the parts of the biodegradable mulch film that are coated with glue.

[0078] In this embodiment, the feeding conveying channel 44 is a rotating groove arranged rotatably inside the seed storage box 42. The outlet of the feeding conveying channel 44 is connected to the feeding channel 43. The outlet end of the feeding channel 43 is an arc-shaped channel, and the width of the arc-shaped channel matches the width of the adhesive protrusion. During the rotation of the rubber roller 30, the seed-adhesive protrusion 38 drives the biodegradable film through the arc-shaped channel and adheres the seeds arranged inside the arc-shaped channel, realizing the seed-adhesive film rolling operation.

[0079] In order to screen out defective seeds and prevent them from being transported onto the biodegradable mulch film, which would affect rice seedling cultivation, a seed selection gap is provided at the bottom of the feeding and conveying channel 44. The opening of the seed selection gap is smaller than the size of normal good seeds. When defective seeds pass through the seed selection gap, they will be screened out, while good seeds will pass through smoothly and be transported.

[0080] Once seeds adhere to the biodegradable mulch film on the rubber roller 30, it will be driven by the transmission system 100 to the next process for seed growth process seam cutting.

[0081] like Figure 10 As shown, the mulch film cutting device 500 in this embodiment is provided in multiple sets, each set corresponding to the position where the seeds are adhered to the biodegradable mulch film. The mulch film cutting device includes a rotating shaft 51 driven by a drive motor and several adjustable cutting blades slidably mounted on the rotating shaft 51; each adjustable cutting blade includes a blade holder wheel 52 and cutting blades mounted on the blade holder wheel. Several blade holder wheels 52 are slidably mounted on the rotating shaft 51, and each blade holder wheel 52 has an inner groove 53. A pair of replaceable adjustable cutting blades 54 are symmetrically arranged inside the inner groove 53, and the distance between the cutting blades 54 is greater than the width of the seed-adhered area on the biodegradable mulch film.

[0082] like Figure 11 As shown, the plastic film cutting device 500 includes a drive motor 50, a rotating shaft 51, and several blade holder wheels 52 mounted on the rotating shaft 51. The rotating shaft 51 is rotatably mounted on the frame 1 and driven to rotate by the drive motor 50. The rotating shaft 51 is positioned directly above the film-spreading roller, and the blade holder wheels 52 are mounted on the rotating shaft 51. Each blade holder wheel 52 is a roller with an inner groove 53. A blade holder mounting groove is provided inside the inner groove 53 of the blade holder wheel 52, and a pair of cutting blades 54 are offset within the blade holder mounting groove. The distance between the two cutting blades 54 is greater than the width of the seed-adhering area on the biodegradable plastic film. When the drive motor 50 drives the rotating shaft 51 to rotate, it drives the blade holder wheels 52 to rotate. During the rotation of the blade holder wheels 52, when the cutting blades 54 rotate to the position where the biodegradable plastic film is adhered to by the seed, growth holes are cut on both sides of the seed-adhering area, thereby facilitating seed growth.

[0083] In this embodiment, the rotation speed of the cutting blade 54 on the blade holder wheel 52 is matched with the transmission speed of the biodegradable mulch film. That is, when the area with seeds on the biodegradable mulch film is conveyed to the area below the blade holder wheel, the cutting blade on the blade holder wheel rotates to the position to be cut, and the cutting operation is realized at the same time.

[0084] The mulch film cutting device is driven by an independent drive motor. Several blade holder wheels are slidably and adjustablely mounted on the rotating shaft, and the spacing between the blade holder wheels is adjustable to meet the cutting requirements of mulch films for different seeds. Inner grooves are provided on the blade holder wheels, allowing for the replacement of different cutting blades for different seed-growing mulch films, thus meeting the universal design requirements of the mulch film cutting device.

[0085] After the biodegradable mulch film with cut growth holes is tensioned by the film tensioning roller, it is conveyed to the seed film winding mechanism 600 for winding.

[0086] like Figure 12 As shown, the seed film winding mechanism includes a seed-forming film roll 61 driven to rotate by a servo motor 62. The seed-forming film roll 61 is mounted on the swing mechanism and swings with the swing mechanism. The swing mechanism includes a swing motor 63 and a swing assembly driven by the swing motor 63.

[0087] Specifically, the seed film winding mechanism 600 includes a winding roller 60, a seed-forming film roll 61 sleeved on the winding roller 60, a servo motor 62, and a swing mechanism. The swing mechanism is mounted on the frame 1. In this embodiment, the swing mechanism includes a swing motor 63 and a swing assembly. The swing assembly includes a swing sliding plate 64 that reciprocates via the swing motor and a set of connecting shafts 65. A fixed plate 66 with a slide rail is mounted on the frame 1. The swing sliding plate 64 is slidably mounted on the fixed plate 66 and reciprocates via the connecting shafts 65. The winding roller 60 is mounted on the swing sliding plate 64 of the swing mechanism via a winding bracket 67 and reciprocates with the swing sliding plate. The winding roller is driven to rotate by the servo motor. The servo motor can adjust the rotation speed of the winding roller, thereby controlling the tightness of the biodegradable mulch film during the winding process.

[0088] During the film winding process, while the servo motor 62 drives the film winding roller 60 to rotate and wind the film, the swing motor 63 drives the swing sliding plate 64 to reciprocate, that is, to slide back and forth along the width direction of the film winding roller, thereby realizing the left and right reciprocating motion of the seed-forming film winding cylinder 61, so that the biodegradable mulch film can be wound on the seed-forming film winding cylinder. This design maximizes the amount of biodegradable mulch film that can be wound on the same seed-forming film winding cylinder.

[0089] In this embodiment, a method for operating an automatic adhesive seed-bonding and film-laying device, using rice as the seed, includes the following steps:

[0090] Step 1: Turn on the power supply and turn on the main control motor to drive the output shaft to rotate. The output gear on the output shaft drives the transmission chain in a linkage manner.

[0091] Step 2: Start the magnetic powder motor. The magnetic powder motor drives the film feeding roller to rotate and feed the film synchronously.

[0092] Step 3: Inject the glue into the glue supply box, activate the glue application roller control switch, and the glue application roller will rotate to pick up the glue from the glue supply box. Then, apply the glue to the raised areas on the biodegradable mulch film that are protruded by the seed-adhesive protrusions on the glue roller. The surface area of ​​the raised areas where the glue is applied is approximately 4 cm². 4cm;

[0093] Step 4: Pour the seeds into the vibrator seed storage box and turn on the vibrator seed storage box switch. The seeds in the vibrator seed storage box will vibrate at high frequency. The biodegradable mulch film with glued raised areas will rotate with the glue roller and pick up the vibrating seeds at the feeding channel. Each raised area will adhere to about 7 rice seeds.

[0094] Step 5: Turn on the switch of the mulch film cutting device. The drive motor drives the blade holder wheel with cutting blades on the rotating shaft to rotate. The cutting blades cut growth holes on both sides of the area where the seeds are attached to the biodegradable mulch film.

[0095] Step 6: Start the servo motor and the swing motor. The servo motor drives the film-taking roller to rotate, while the swing motor drives the swing mechanism shaft to swing back and forth along the axis of the film-taking roller, thereby rotating and taking in the biodegradable mulch film with seeds on the seed-forming film roll.

[0096] In this embodiment, the swing motor drives the film-taking shaft to reciprocate about 10cm along the axial direction, thereby causing the film-taking roller to rotate and take in the seed-forming film roll.

[0097] Example 2:

[0098] exist Figure 13 In the illustrated embodiment, an automatic adhesive application and film placement device has a technical solution that is basically the same as that in Embodiment 1, except that:

[0099] The seed-adhesive protrusions 38 on the rubber roller 30 are built-in and replaceable separate components. Specifically, a seed-adhesive protrusion replacement structure 304 with an impeller structure is provided inside the rubber roller 30, and the required seed-adhesive protrusion replacement holes 305 are opened on the rubber roller 30 accordingly. The impeller-type seed-adhesive protrusion replacement structures are distributed along the axial direction of the rubber roller 30, and each seed-adhesive protrusion replacement structure has a seed-adhesive protrusion 38 on its impeller structure. When performing seed-adhesive operations for different seeds, only the seed-adhesive protrusion on the impeller-type seed-adhesive protrusion replacement structure 304 needs to be replaced. In use, the seed-adhesive protrusion extends out from the seed-adhesive protrusion replacement hole on the rubber roller and protrudes on the roller surface of the rubber roller to protrude the seed-adhesive position of the biodegradable mulch film, thereby realizing the gluing and seed-adhesive operations.

[0100] The seed-adhesive protrusion replacement structure 304 includes an outer tube 306 and a telescopic rod 307 slidably disposed inside the outer tube 306. The lower end of the telescopic rod 307 is connected to a cylinder 308. The seed-adhesive protrusion 38 is movably disposed at the upper end of the telescopic rod 307. The extension and retraction of the cylinder drives the telescopic rod 307 to extend and retract radially along the rubber roller 30, thereby realizing the replacement operation of the seed-adhesive protrusion.

[0101] By replacing the seed-binding protrusions with the structure 304, the rubber roller can be made universally compatible. By simply replacing the internal seed-binding protrusion replacement structure 304, different seed-binding protrusions can be replaced to meet the seed-binding requirements of different seeds.

[0102] In this embodiment, a method for automatically applying adhesive, bonding seeds, and placing film is described as follows:

[0103] First, select a suitable seed-binding protrusion and replace the seed-binding protrusion on the rubber roller. At the same time, adjust the relative positions of the gluing device and the seed storage and feeding device, and adjust the relative position of the blade holder in the cutting device on the rotating shaft to complete the adaptation adjustment of all devices.

[0104] Next, turn on the power supply, start the main control motor to drive the output shaft to rotate, and the output gear on the output shaft will drive the transmission chain to move in tandem. Start the magnetic powder motor, which will drive the film feeding roller to rotate for synchronous film feeding. Inject the adhesive into the adhesive supply box, start the adhesive application wheel control switch, and the adhesive application wheel will rotate to pick up the adhesive from the supply box. Then, brush it onto the raised areas of the biodegradable mulch film, with a surface area of ​​approximately 3 cm². 3cm, pour the seeds into the vibrating seed storage box device, turn on the vibrating seed storage box device switch, the seeds in the vibrating seed storage box device will vibrate at high frequency. As the raised parts of the biodegradable mulch film with adhesive rotate, it will pick up the seeds vibrating in the seed storage box device. Each seed-sticking raised part will adhere to about 5 seeds. Turn on the mulch film cutting device switch, the blade holder wheel will rotate, and the blade of the cutting device will cut process slits on both sides of the unfolded biodegradable mulch film at the adhesive position to facilitate seed growth. Start the servo motor and the swing motor. The servo motor drives the film taking roller to rotate, and at the same time the swing motor drives the swing mechanism shaft to swing back and forth along the axis of the film taking roller, thereby rotating and taking the biodegradable mulch film with seeds on the seed-sticking forming film roll. In this embodiment, the swing motor drives the film taking shaft to reciprocate about 15cm along the axis, so that the film taking roller drives the seed-sticking forming film roll to rotate and take the film.

[0105] Example 3:

[0106] exist Figure 14 , Figure 15 In the illustrated embodiment, an automatic adhesive application and seed film placement device has a technical solution that is basically the same as that in Embodiment 1, except that:

[0107] The glue injection and supply system 300 is fixed on the frame 1. The glue injection and supply system 300 includes a glue roller 30 and several glue application devices 31.

[0108] Each glue application device 31 includes a high-pressure glue cylinder 310, a high-pressure glue spray head 312 connected to the high-pressure glue cylinder 310 via a glue tube 311, and a glue control device. The glue control device includes a glue surface control plate 313, a glue baffle plate 317, a glue receiving tank 315, and a glue recovery device 316. The glue surface control plate 313 is located near the glue roller 30. The glue surface control plate 313 has glue control openings 314 corresponding to the number of adhesive seed protrusions 38 on the glue roller. The size of the glue control openings 314 is set according to the size of the adhesive seed protrusions. A glue receiving tank 315 is located at the lower part of the glue surface control plate 313, and the glue receiving tank 315 is connected to a glue recovery device 316. A glue baffle plate 317 is located at the top of the glue surface control plate 313. When gluing is required, the high-pressure glue cylinder is activated. The glue inside the cylinder flows through a hose into the high-pressure spray head, which sprays intermittently at the control nozzle. Specifically, when the seed-binding protrusion rotates to the control nozzle position, the high-pressure spray head sprays glue onto the protrusion, then stops spraying. When the next seed-binding protrusion appears, the high-pressure spray head sprays glue again momentarily. The amount of glue sprayed per burst can be set according to the seed-binding needs, achieving different glue thicknesses. This gluing device allows for adjustable and controllable glue settings. Furthermore, a baffle plate is installed at the top of the glue control plate to prevent glue mist from spreading during spraying, while a glue collection tank is located at the bottom of the control plate to collect excess glue and recycle it via a glue recovery device. This gluing device achieves timed and quantitative glue spraying, effectively controlling the glue amount and ensuring consistent and uniform glue thickness on the seed-binding protrusions. It allows for adjustable glue amount settings for different seeds, resulting in good seed-binding performance and is economical and practical.

[0109] like Figure 16 As shown, in this embodiment, the seed storage and loading device 400 includes a vibrator 40, a vibration motor 41, a seed storage box 42, and a turntable 47 disposed inside the seed storage box. The vibration motor drives the vibrator to vibrate and rotate. During the rotation, the seeds inside the seed storage box enter the surface of the turntable 47 and come into dynamic contact with the rubber roller during vibration. When the seed-adhesive protrusion on the rubber roller, which is coated with biodegradable mulch film, rotates to the position on the turntable, it adheres the seeds thereon, thus achieving seed adhesion.

[0110] The automatic seed-adhesive and film-laying system in the above embodiments can achieve uniform seedling distribution for rice and other crops, improve seedling emergence rate during the seedling growth period, and thus increase the yield of rice and other plants. It eliminates the two processes of manual pre-seeding and manual transplanting, greatly reducing the heavy physical labor of farmers and liberating labor and productivity. When used in conjunction with film-laying machinery, the mechanical arms can handle the material, reducing the labor intensity of equipment operators and accelerating production. By using nutrient adhesive, which maintains a certain viscosity and melts and decomposes upon contact with water, the problem of adhesion between the plastic film and seeds is solved, as well as the problem of seeds not falling off after the film is laid on the ground is also solved.

[0111] More importantly, this automatic seed gluing and film-laying equipment features a universal design, capable of meeting the needs of gluing and film-laying different seeds. Any plant requiring breeding operations can undergo seed gluing and film-laying using this equipment, greatly enhancing its practicality and versatility. Furthermore, it maximizes film-laying efficiency, reducing the frequency of changing the seed-forming film-laying cylinder and improving work efficiency.

[0112] The above embodiments are only one part of the embodiments of the present invention, and not all of the embodiments. Furthermore, based on the embodiments described in this invention, all other embodiments obtained by those skilled in the art without inventive effort and based on the technical solutions of this application should fall within the scope of protection of this invention.
