Description

Technical Field

[0001] The invention belongs to the technical field of seed processing, in particular to a method for adapting small particle seeds to multiple environmental stresses and pelletizing them in an industrialized process. Background Art

[0003] Plasma seed processing technology is currently an advanced seed pre-sowing treatment technology. This technology can etch the seed coat, increase the permeability of the seed coat, break the seed dormancy, and enhance its adaptability and resistance. However, the field environment is complex, and agricultural production faces a variety of environmental stresses such as pests, drought, climate change, and salinity. Therefore, whether the seeds can germinate smoothly and grow healthily has become a key link in the field growth process of crops. Seed pelleting technology is a key pre-sowing treatment technology. It changes the shape of the seeds themselves to improve their sowing performance by wrapping multiple layers of protective or functional materials on the surface of the seeds, and provides them with a reliable and safe growth environment in the field. This can not only effectively prevent and control pests and ensure seed growth, but also add active substances and nutrients to the pelletized powder to create a beneficial microenvironment for seed growth.

[0004] Although plasma seed treatment technology can significantly improve the germination performance of seeds and create a favorable internal growth environment for them, seeds still face challenges in germination and growth in complex field environments. Although pelletized seeds can provide a good external environment for field growth, if the internal growth environment of the seeds themselves is not good, it is difficult to achieve complete germination and growth. Therefore, the organic combination of plasma seed processing technology and seed pelleting technology can create high-performance seeds that have both an excellent internal environment for germination and growth and a beneficial external environment for field growth. This can not only fully guarantee the effective expression of excellent genes in seeds, but also promote the growth and development of crops, thereby increasing the yield of field crops. Summary of the invention

[0005] In order to overcome the defects of the prior art, the present invention provides a method for small-particle seed adaptation to multiple environmental stresses and pelletization factory processing, which can create high-performance seeds that have both an excellent internal environment for germination and growth and an external environment that is beneficial to field growth.

[0006] To achieve the above-mentioned purpose, the present invention provides a method for factory-based treatment of small-particle seeds adapted to multiple environmental stresses and pelletized, the equipment to be included in the method is a high-frequency micro-vibration seed uniform distribution device, a plasma seed multi-environmental stress adaptation treatment equipment arranged at the end of the discharge port of the high-frequency micro-vibration seed uniform distribution device, a seed pelletizing equipment arranged behind the plasma seed multi-environmental stress adaptation treatment equipment, and a matching multi-layer continuous drying equipment.

[0007] Based on the above equipment, the implementation of the treatment process method includes the following steps: S10, starting the entire device in the human-machine interaction interface, and each device is started in reverse order from the back to the front through the central processor setting program; S20, small particle seeds are put into the silo of the high-frequency micro-vibration seed uniform distribution device, and the silo door is opened after detection by the gravity sensor at the bottom of the silo, and the seeds are transported to the seed scattering channel through multiple parallel spiral feeding channels, and the seed flow is spread in a single layer in the seed scattering channel through high-frequency micro-vibration; S30, the single-layer flat seeds fall from the end of the seed scattering channel into the conveyor belt of the plasma seed multi-environmental stress adaptation treatment equipment, and the seeds are transported to the plasma seed treatment area; S40, a stable glow discharge phenomenon is formed between the plates in the plasma seed treatment area, and the flat seeds pass through the plasma seed treatment area at a uniform speed, so that the seeds can acquire the ability to cope with various environmental stresses after being treated by plasma, and the treated seeds leave the area and enter the seed collection bin; S50, the first vertical auger hoist vertically lifts the seeds from the first seed collecting bin to a weighing device disposed above the seed pelletizing device; S60, after the seed weight reaches the weight value set by the weighing device of the pelletizing equipment, the seed falls into the pelletizing bin of the seed pelletizing equipment below, and the first spinning disc rotates to drive the seed to rotate; S70, the peristaltic droplet supply device drips a solution amount suitable for the amount of seeds into the atomizing disk disposed in the seed pelletizing device, and the second disk rotates at a high speed to centrifugally atomize the water droplets and sprays them onto the outer wall of the rotating seeds; S80, the peristaltic droplet supply device stops supplying liquid, and the uniform micro-vibration powder supply device uniformly supplies a pelletizing powder dosage that matches the seed quantity into the pelletizing bin; S90, repeat steps S70 and S80; S100, when the diameter of the seed pelletized particles reaches a preset value, the pelletizing chamber door automatically opens, the pelletized seed wet particles leave the pelletizing chamber and enter the second seed collecting chamber, and the first spinning disc stops rotating; S110, the second vertical auger hoist lifts the seeds from the second seed collection bin to the first-layer conveyor mesh belt of the multi-layer continuous drying equipment, and slowly rotates to convey the pelletized seed wet particles to the second-layer and third-layer conveyor mesh belts; S120, when the pelletized seed particles reach the end of the third-layer conveyor belt of the multi-layer continuous drying device, the seed pelletized particles become dry from wet and leave the drying device, thereby obtaining pelletized seed dry particles that can cope with various environmental stresses; S130, shutting down the entire device in the human-machine interaction interface, and shutting down each device in sequence from front to back according to the program set by the central processor.

[0008] Based on the above scheme, the specific steps in S10 include: S11, placing the seeds in the deep vision seed detection sensor below the human-computer interaction interface for detection; S12. Based on the detection of seeds by the deep vision seed detection sensor, the seed type and seed diameter can be obtained. The built-in program of the central processor will calculate the plasma generation power suitable for the seeds and the conveyor belt speed value of the plasma seed multi-environmental stress adaptation treatment equipment, and adjust the plate spacing of the plasma seed treatment area; Based on the above scheme, the specific steps in S20 include: S21, after the seeds enter the seed scattering channel, the seed scattering channel exciter will gradually increase the excitation frequency and amplitude, and the visual acceleration sensor set above the seed scattering channel will detect the single sliding acceleration of the seeds in the seed scattering channel and feed it back to the central processor; S22. When the central processor detects that the single sliding acceleration of the seed particles is just greater than zero, the excitation frequency and amplitude are slightly reduced to ensure that the seeds perform a controlled rolling motion in the seed scattering channel without jumping; S23. The central processing unit saves the excitation frequency and amplitude obtained in S22 as process parameters for subsequent seed dispersion processing of this type.

[0009] Based on the above solution, the specific steps in S40 include: S41, a temperature sensor disposed above the plasma seed treatment area monitors the area temperature in real time; S42, when the temperature sensor value exceeds 20°C for the first time, the refrigeration compressor starts, and the vaporization evaporator absorbs heat to ensure that the temperature value of the plasma seed treatment area does not exceed 20°C to avoid damaging the physiological activity of the seeds; S43. The conveyor belt high-frequency micro-vibration exciter inherits the working parameters of the seed scattering channel exciter, so that the seeds on the conveyor belt can achieve a tumbling state, thereby achieving a uniform immersion effect of plasma seed treatment when the seeds pass through the plasma seed treatment area.

[0010] Based on the above solution, the specific steps in S60 include: S61. When the seed weight reaches the set weight value, the blocking door arranged in the upper middle part of the weighing device of the seed pelletizing equipment is closed to prevent the plasma-treated seeds from falling into the weighing device again; S62, the door below the weighing device is opened, and the seeds fall into the pelletizing bin of the seed pelletizing equipment; S63. After the weighing value of the weighing device returns to zero, the door below the device is closed to prevent the door from opening again.

[0011] Based on the above solution, the specific steps in S90 include: S91, according to the seed diameter and type, the central processing unit calculates the control time of powder supply, liquid supply and the interval between the two according to the pilling mechanism model; S92, the program in the central processing unit sets the powder-liquid mass ratio of the uniform micro-vibration powder supply device and the peristaltic droplet supply device to 2:1, and the powder-liquid mass ratio remains unchanged during the repetition of steps S70 and S80, but the supply rate of the uniform micro-vibration powder supply device and the peristaltic droplet supply device increases linearly with the increase in the number of repetitions, thereby changing the liquid supply amount and the powder supply amount; S93. The anti-sticking depth camera built into the pelletizing bin continuously detects the diameter of the seed pelletized particles. When the diameter of 80% of the particles in the detection area is greater than the preset value, the anti-sticking depth camera sends a signal to the central processor to open the pelletizing bin door.

[0012] Based on the above solution, the specific steps in S110 include: S111, multi-layer continuous drying equipment, three layers of conveyor belt nets are arranged in a staggered manner, with the same rotation speed, the first and third layers of conveyor belt nets rotate in the same direction, and the second layer of conveyor belt net rotates in the opposite direction to the first and third layers of conveyor belt nets; S112, the vaporization heat absorbing evaporator in the plasma seed treatment area is connected to the condensing fan of the multi-layer continuous drying equipment through a compressor, and the refrigerant in the pipeline is liquefied and releases heat in the condenser and blown out through the fan, and the heat is used for seed pelletization and wet particle drying; Based on the above solution, the specific steps in S120 include: S121. When the wet seed pellets fall into the sorting port from the end of the third-layer conveyor belt, the batch of wet seed pellets is tested for moisture by an infrared moisture detector. When the moisture content of the batch is less than 7%, the wet seed pellets can be regarded as dry particles, the blocking door of the sorting port is opened, the electric push rod is retracted to open the drying outlet door, and the dry particles leave the drying equipment; otherwise, the blocking door of the sorting port is opened, the electric push rod is extended to close the drying outlet door, and the wet seed pellets enter the second seed collection bin again via the track; S122, the central processing unit program analyzes the data transmitted by the infrared moisture detector. When the moisture content of the batch is less than 7%, no action is taken. Otherwise, the moisture content data is input into the preset calculation model to calculate the required calorific value; S123, when the heat blown out by the condensing fan is insufficient to meet the drying requirement, the finned tube heater arranged in front of the condensing fan is started, and the heat generated by the finned tube heater blown out by the fan is used to dry the seed pelletized wet particles; S124, repeat S121, S122 and S123 until the moisture content of the seed pelletized particles detected by the infrared moisture detector is less than 7%, and the seed pelletized dry particles leave the drying equipment.

DETAILED DESCRIPTION

[0017] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0018] In the description of the present invention, it is necessary to understand that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] The embodiment of the present invention provides a method for small-particle seed multi-environmental stress adaptation and pelleting factory processing, which can create high-performance seeds that have both an excellent germination and growth internal environment and a beneficial field growth external environment. This can not only fully guarantee the effective expression of seed excellent genes, but also promote the growth and development of crops, thereby increasing the yield of field crops. The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 , 2 As shown in Figure 3, the present invention provides a method for factory-based treatment of small-particle seeds adapted to multiple environmental stresses and pelletized, and the equipment to be implemented includes a high-frequency micro-vibration seed uniform distribution device, a plasma seed multi-environmental stress adaptation treatment equipment arranged at the end of the discharge port of the high-frequency micro-vibration seed uniform distribution device, a seed pelletizing equipment arranged behind the plasma seed multi-environmental stress adaptation treatment equipment, and a matching multi-layer continuous drying equipment.

[0021] Based on the above equipment, the implementation of the treatment process method includes the following steps: S10, starting the entire device in the human-machine interaction interface, and each device is started in reverse order from the back to the front through the central processor setting program; The following steps should be included before implementing S10: S11. In order to realize information interaction between the machine and seeds and achieve high adaptability of machine parameters to different seed processing, a deep vision sensor arranged below the human-machine interaction interface is used to detect seeds; S12, according to the detection of the seeds by the deep vision seed detection sensor, the seed type and seed diameter are obtained, and the built-in program of the central processing unit calculates the plasma generation power suitable for the seeds and the conveyor belt speed value of the plasma seed multi-environmental stress adaptation treatment equipment, and adjusts the plate spacing of the plasma seed treatment area; This step interacts the seed parameters with the machine processing parameters, provides the correct working parameters for subsequent seed processing, realizes highly intelligent control, reduces the professional and technical requirements for technicians, ensures the seed processing effect, and lays the foundation for the smooth growth of seeds in the field.

[0022] S20, small particle seeds are put into the silo of the high-frequency micro-vibration seed uniform distribution device, and the silo door is opened after detection by the gravity sensor at the bottom of the silo, and the seeds are transported to the seed scattering channel through multiple parallel spiral feeding channels, and the seed flow is spread in a single layer in the seed scattering channel through high-frequency micro-vibration; Based on the above solution, the specific steps in S20 also include: S21, after the seeds enter the seed scattering channel, the seed scattering channel exciter will gradually increase the excitation frequency and amplitude, and the visual acceleration sensor set above the seed scattering channel will detect the single sliding acceleration of the seeds in the seed scattering channel and feed it back to the central processor; S22. When the central processor detects that the single sliding acceleration of the seed particles is just greater than zero, the excitation frequency and amplitude are slightly reduced to ensure that the seeds perform a controlled rolling motion in the seed scattering channel without jumping; S23. The central processing unit saves the excitation frequency and amplitude obtained in S22 as process parameters for subsequent seed dispersion processing of this type.

[0023] This step uses the adaptive adjustment method of control parameters. In the initial treatment, it is necessary to efficiently find the optimal working parameters, and then it can operate normally. In the subsequent treatment process, the system will make fine adjustments within the optimal working parameter range to ensure the single-layer tiling effect of the seed flow, creating a solid and excellent foundation for the subsequent plasma seed treatment, ensuring the smoothness and efficiency of the entire seed treatment process.

[0024] S30, the single-layer flat seeds fall from the end of the seed scattering channel into the conveyor belt of the plasma seed multi-environmental stress adaptation treatment equipment, and the seeds are transported to the plasma seed treatment area; S40, a stable glow discharge phenomenon is formed between the plates in the plasma seed treatment area, and the flat seeds pass through the plasma seed treatment area at a uniform speed, so that the seeds can acquire the ability to cope with various environmental stresses after being treated by plasma, and the treated seeds leave the area and enter the seed collection bin; Based on the above solution, the specific steps in S40 also include: S41, a temperature sensor disposed above the plasma seed treatment area monitors the area temperature in real time; S42, when the temperature sensor value exceeds 20°C for the first time, the refrigeration compressor starts, and the vaporization evaporator absorbs heat to ensure that the temperature value of the plasma seed treatment area does not exceed 20°C to avoid damaging the physiological activity of the seeds; S43. The conveyor belt high-frequency micro-vibration exciter inherits the working parameters of the seed scattering channel exciter, so that the seeds on the conveyor belt can achieve a tumbling state, thereby achieving a uniform immersion effect of plasma seed treatment when the seeds pass through the plasma seed treatment area.

[0025] During the atmospheric pressure plasma seed treatment process, the temperature of the glow discharge area will rise to a certain extent. Seeds are living organisms with vitality. In order to avoid the loss of seed activity, a temperature control device is used to control the temperature range. In particular, the temperature control device is in the same system as the condenser in the multi-layer continuous drying equipment. The fan will reuse the heat output by the condenser for drying, reducing the power consumption in the entire process method.

[0026] S50, the first vertical auger hoist vertically lifts the seeds from the first seed collecting bin to a weighing device disposed above the seed pelletizing device; S60, after the seed weight reaches the weight value set by the weighing device of the pelletizing equipment, the seed falls into the pelletizing bin of the seed pelletizing equipment below, and the first spinning disc rotates to drive the seed to rotate; Based on the above solution, the specific steps in S60 also include: S61. When the seed weight reaches the set weight value, the blocking door arranged in the upper middle part of the weighing device of the seed pelletizing equipment is closed to prevent the plasma-treated seeds from falling into the weighing device again; S62, the door below the weighing device is opened, and the seeds fall into the pelletizing bin of the seed pelletizing equipment; S63. After the weighing value of the weighing device returns to zero, the door below the device is closed to prevent the door from opening again.

[0027] The weighing device in this step ensures the precise proportion of batch seed pelleting. At the same time, the setting of the blocking chamber door ensures the accuracy of the weighing and also ensures the orderliness and continuity of the overall process.

[0028] S70, the peristaltic droplet supply device drips a solution amount suitable for the amount of seeds into the atomizing disk disposed in the seed pelletizing device, and the second disk rotates at a high speed to centrifugally atomize the water droplets and sprays them onto the outer wall of the rotating seeds; S80, the peristaltic droplet supply device stops supplying liquid, and the uniform micro-vibration powder supply device uniformly supplies a pelletizing powder dosage that matches the seed quantity into the pelletizing bin; S90, repeat steps S70 and S80; Based on the above solution, the specific steps in S90 also include: S91, according to the seed diameter and type, the central processing unit calculates the control time of powder supply, liquid supply and the interval between the two according to the pilling mechanism model; S92, the program in the central processing unit sets the powder-liquid mass ratio of the uniform micro-vibration powder supply device and the peristaltic droplet supply device to 2:1, and the powder-liquid mass ratio remains unchanged during the repetition of steps S70 and S80, but the supply rate of the uniform micro-vibration powder supply device and the peristaltic droplet supply device increases linearly with the increase in the number of repetitions, thereby changing the liquid supply amount and the powder supply amount; S93. The anti-sticking depth camera built into the pelletizing bin continuously detects the diameter of the seed pelletized particles. When the diameter of 80% of the particles in the detection area is greater than the preset value, the anti-sticking depth camera sends a signal to the central processor to open the pelletizing bin door.

[0029] The correct powder and liquid supply in this step is the key to the success of seed pelleting. With the help of highly intelligent powder and liquid supply and control strategies, it is conducive to the realization of factory-based seed pelleting production. Among them, the use of depth cameras to detect the diameter of seed pellet particles ensures the continuous production of the entire process.

[0030] S100, when the diameter of the seed pelletized particles reaches a preset value, the pelletizing chamber door automatically opens, the pelletized seed wet particles leave the pelletizing chamber and enter the second seed collecting chamber, and the first spinning disc stops rotating; S110, the second vertical auger hoist lifts the seeds from the second seed collection bin to the first-layer conveyor belt of the multi-layer continuous drying equipment, and slowly rotates to convey the pelletized seed wet particles to the second-layer and third-layer conveyor belts; Based on the above solution, the specific steps in S110 also include: S111, multi-layer continuous drying equipment, three layers of conveyor belt nets are arranged in a staggered manner, with the same rotation speed, the first and third layers of conveyor belt nets rotate in the same direction, and the second layer of conveyor belt net rotates in the opposite direction to the first and third layers of conveyor belt nets; S112. The vaporization heat absorbing evaporator in the plasma seed treatment area is connected to the condensing fan of the multi-layer continuous drying equipment through a compressor. The refrigerant in the pipeline is liquefied and releases heat in the condenser and is blown out through the fan. The heat is used for seed pelletization and wet particle drying.

[0031] S120, when the pelletized seed particles reach the end of the third-layer conveyor belt of the multi-layer continuous drying device, the seed pelletized particles become dry from wet and leave the drying device, thereby obtaining pelletized seed dry particles that can cope with various environmental stresses; Based on the above solution, the specific steps in S120 also include: S121. When the wet seed pellets fall into the sorting port from the end of the third-layer conveyor belt, the batch of wet seed pellets is tested for moisture by an infrared moisture detector. When the moisture content of the batch is less than 7%, the wet seed pellets can be regarded as dry particles, the blocking door of the sorting port is opened, the electric push rod is retracted to open the drying outlet door, and the dry particles leave the drying equipment; otherwise, the blocking door of the sorting port is opened, the electric push rod is extended to close the drying outlet door, and the wet seed pellets enter the second seed collection bin again via the track; S122, the central processing unit program analyzes the data transmitted by the infrared moisture detector. When the moisture content of the batch is less than 7%, no action is taken. Otherwise, the moisture content data is input into the preset calculation model to calculate the required calorific value; S123, when the heat blown out by the condensing fan is insufficient to meet the drying requirement, the finned tube heater arranged in front of the condensing fan is started, and the heat generated by the finned tube heater blown out by the fan is used to dry the seed pelletized wet particles; S124, repeat S121, S122 and S123 until the moisture content of the seed pelletized particles detected by the infrared moisture detector is less than 7%, and the seed pelletized dry particles leave the drying equipment.

[0032] In this step, multi-layer continuous drying is combined with moisture detection and identification, which improves the qualified rate of seed pelletized particles and avoids a series of seed growth problems caused by unreasonable moisture content of seed pelletized particles.

[0033] S130, shutting down the entire device in the human-machine interaction interface, and shutting down each device in sequence from front to back according to the program set by the central processor.

[0034] The present invention provides a method for small-particle seeds to adapt to multiple environmental stresses and to be pelletized in a factory, and the process method supports highly automated control. In the seed pre-detection process, information interaction between seed information and machine processing parameters is realized, ensuring the adaptability of processing parameters and seed types in the entire process method. The adaptive parameter control strategy in the single-layer flat feeding and seed pelletization process provides intelligent guarantee for its functional realization. The evaporator in the plasma seed treatment area realizes temperature control and the condenser in the multi-layer continuous drying equipment releases heat to achieve drying. The two are in the same system, realizing the collection and utilization of waste heat, improving the utilization rate of the device, and reducing the overall power consumption. The posture control of seeds in the process method ensures the effect of seed treatment and the good internal environment of seed production, thereby achieving the effect of increasing field production.

A method for processing small-particle seeds to adapt to multiple environmental stresses and pelletize them in an industrialized manner as claimed in claim 6, characterized in that: The S110 further includes the following steps: S111, multi-layer continuous drying equipment, three layers of conveyor belt nets are arranged in a staggered manner, with the same rotation speed, the first and third layers of conveyor belt nets rotate in the same direction, and the second layer of conveyor belt net rotates in the opposite direction to the first and third layers of conveyor belt nets; S112. The vaporization heat absorbing evaporator in the plasma seed treatment area is connected to the condensing fan of the multi-layer continuous drying equipment through a compressor. The refrigerant in the pipeline is liquefied and releases heat in the condenser and is blown out through the fan. The heat is used for drying the seed pelletizing wet particles.

8. The method for processing small-particle seeds to adapt to multiple environmental stresses and pelletize them in an industrialized manner as claimed in claim 6, characterized in that: The S120 further includes the following steps: S121. When the wet seed pellets fall into the sorting port from the end of the third-layer conveyor belt, the batch of wet seed pellets is tested for moisture by an infrared moisture detector. When the moisture content of the batch is less than 7%, the wet seed pellets can be regarded as dry particles, the blocking door of the sorting port is opened, the electric push rod is retracted to open the drying outlet door, and the dry particles leave the drying equipment; otherwise, the blocking door of the sorting port is opened, the electric push rod is extended to close the drying outlet door, and the wet seed pellets enter the second seed collection bin again via the track; S122, the central processing unit program analyzes the data transmitted by the infrared moisture detector. When the moisture content of the batch is less than 7%, no action is taken. Otherwise, the moisture content data is input into the preset calculation model to calculate the required calorific value; S123, when the heat blown out by the condensing fan is insufficient to meet the drying requirement, the finned tube heater arranged in front of the condensing fan is started, and the heat generated by the finned tube heater blown out by the fan is used to dry the seed pelletized wet particles; S124, repeat S121, S122 and S123 until the moisture content of the seed pelletized particles detected by the infrared moisture detector is less than 7%, and the seed pelletized dry particles leave the drying equipment.
