Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a seed dressing device for Elymus seeds and a use method thereof. Background Art

[0002] Elymus seeds are caryopsis, with a thousand-grain weight of about 3 to 5 grams, and most Elymus seeds have long awns. Generally, Elymus seeds include glumes (glumes and lemmas) and paleas (paleas and lemmas). Among them, short awns (usually about 5.0 mm in length) grow on the glumes, while the awns on the lemma of the seeds are longer, generally rough awns of 10.0 to 20.0 mm, and the entire surface of the Elymus seeds will be covered with long awns. Usually, before sowing Elymus seeds, they will be mixed with seeds to improve the germination rate and stress resistance of the seeds. During the seed mixing process, it is necessary to ensure that the seeds are fully mixed with the seed dressing agent (such as pesticides, fertilizers or biological agents) while avoiding damage to the seeds.

[0003] A search revealed a seed dressing device disclosed in patent publication number CN109220075B, which includes two screens, each of which includes a frame, multiple first adjustment rods, multiple second adjustment rods, and four sets of fixing components. Each side of the frame is recessed to form a receiving slot, and each receiving slot has a corresponding set of fixing components. A liquid spraying mechanism includes a hollow crossbar and a hollow spray bar. The multiple spray bars are recessed to form multiple positioning slots, each of which has multiple spraying components. While this structure can achieve both screening and seed dressing functions, due to the small mass of individual Elymus seeds and their long awns on their surface, they easily adhere to the sides of the mixing chamber after mixing with the reagent, and also tend to form clumps, affecting seed dressing efficiency. Similar problems also exist with some existing seed dressing devices, such as the traditional vertical mixer (JX-78-69).

[0004] Therefore, the present invention provides a seed dressing device for Elymus seeds and a method of using the same to solve the above problems. Summary of the Invention

[0005] To solve the above problems, the present invention provides a seed dressing device for Elymus seeds and a method of use thereof. Through a two-way stirring mechanism, the seed dressing efficiency is improved while the combined air transmission system synchronously completes the self-cleaning of the cavity wall and assists the penetration of the liquid medicine.

[0006] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows: a seed dressing device for Elymus spp. and a method for using the same, comprising a box body, wherein the interior of the box body is provided with a seed mixing chamber and a seed discharge chamber from top to bottom, a feed port connected to the seed mixing chamber is installed at the top of the box body, and a partition assembly for separating the seed mixing chamber from the seed discharge chamber is provided between the seed mixing chamber and the seed discharge chamber; a seed dressing assembly for stirring Elymus spp. is provided inside the seed mixing chamber, and the seed dressing assembly is threadedly connected to a translation assembly for driving the seed dressing assembly to move horizontally; spraying assemblies for spraying liquid medicine are installed on both sides of the seed mixing assembly;

[0007] Several extrusion chambers are symmetrically arranged on both sides of the length direction of the box body, and extrusion blocks are movably fitted in the extrusion chambers. The extrusion blocks are fixedly connected to the seed mixing chamber on the side close to the seed mixing chamber, and the telescopic rods extend into the seed mixing chamber at the ends away from the extrusion blocks and are fixedly connected to the translation assembly; several air transmission channels are opened at the ends of the extrusion chambers away from the seed mixing chamber, and several air injection holes are opened on both sides of the width direction of the mixing chamber, and the air transmission channels are connected to the air injection holes.

[0008] Basic Solution Principle: A translational assembly drives the seed mixing assembly to move horizontally back and forth along the seed mixing chamber, expanding the mixing coverage and preventing seed accumulation. Simultaneously, the assembly rotates while moving, applying multi-directional shear forces to the seeds and improving mixing uniformity. As the seed mixing assembly moves horizontally, the telescopic rod pushes the corresponding extrusion block to compress the air within the chamber. The compressed air is ejected at high speed through the air transmission channel and out of the jet orifice. The airflow from the jet orifice disperses seed clumps, promoting atomization and diffusion of the liquid medicine. The airflow from the jet orifice impacts the side walls of the seed mixing chamber, removing adhered seeds or liquid medicine residue. A cleaning plate simultaneously scrapes the chamber walls to prevent residue. During seed mixing, the curved baffle closes to prevent seed leakage. During seed dispensing, the sliding baffle separates, allowing the seeds to fall into the dispensing chamber.

[0009] The adoption of the above scheme has the following beneficial effects: 1. Compared with the existing technology, this scheme forms a spatially staggered two-way stirring path through the composite motion of translational drive and rotational stirring, effectively breaking the problem of seed accumulation or mixing dead corners caused by traditional single-direction stirring. Horizontal movement expands the stirring range to ensure full coverage of the cavity; the rotating blades produce a coupling effect of centrifugal force and shear force, so that the seeds and the liquid medicine are fully in contact during tumbling and throwing. The synchronously triggered compressed air flow is directionally sprayed through the jet hole. On the one hand, it forces the atomized particles of the liquid medicine to diffuse into the gaps between the seeds, overcomes the surface tension and achieves deep coating; on the other hand, it uses the impact of the airflow to disturb the dynamic dispersion of the seed agglomerates, avoiding uneven coating caused by local agglomeration. The synergistic effect of airflow and mechanical stirring significantly shortens the mixing cycle and ensures the uniform distribution of the agent;

[0010] 2. In this solution, the horizontal movement of the translation component directly drives the extrusion blocks on both sides through the telescopic rod, converting mechanical energy into air pressure energy, and realizing the airflow generation and injection function without additional power. The inclined design of the jet hole allows the airflow to stick to the cavity wall to form a swirling effect, and cooperates with the synchronous scraping action of the cleaning plate to thoroughly remove the wet and sticky seeds or medicinal residues adhering to the wall, eliminating the risk of mold growth on the residue. This linkage design breaks through the limitations of traditional cleaning that relies on manual or independent air pumps. It automatically maintains the cleanliness of the cavity during the seed mixing process and ensures the hygiene and safety of multiple batches of operations. In addition, the arc-shaped baffle achieves complete sealing of the cavity during seed mixing and ensures smooth falling of seeds during seeding through precise control of the misalignment and alignment of the through holes. The opening and closing of the dynamic partition structure is coordinated with the stirring and jetting actions, and the overall operation is efficient and there is no risk of secondary pollution.

[0011] Furthermore, the partition assembly includes arc seats symmetrically arranged on both sides of the box body, and the arc seats are provided with arc sliding grooves on the sides close to each other, and arc baffles are slidably fitted in the arc sliding grooves.

[0012] Beneficial effects: The curved baffle can dynamically adjust the sealing and seeding status by sliding, avoiding seed leakage and ensuring smooth seeding; the curved surface eliminates right-angle dead corners, reduces seed residue on the wall, and cooperates with air flow flushing to achieve self-cleaning of the cavity; the structure is compact and adapted to the motion trajectory of the stirring component, improving space utilization and operational coordination.

[0013] Furthermore, a plurality of through holes are opened on the surface of the arc-shaped baffle.

[0014] Beneficial effects: The through holes on the surface of the arc-shaped baffle can filter excess liquid medicine during the seed mixing process, allowing excess liquid medicine to flow into the seed cavity through the through holes for temporary storage or discharge, avoiding excessive seed infiltration and adhesion; at the same time, the through holes form microchannels to assist airflow in penetrating the seed layer and accelerate the uniform adsorption of liquid medicine.

[0015] Furthermore, the translation assembly includes a translation motor arranged in the box body, and the output shaft of the translation motor is coaxially fixedly connected to a threaded rod, the threaded rod extends into the seed mixing chamber away from one end of the translation motor and is rotatably connected to the inner wall of the seed mixing chamber, a nut seat is threadedly connected to the threaded rod, and a limit rod is symmetrically slidingly provided on the nut seat, and both ends of the limit rod are respectively fixedly connected to the two inner walls of the seed mixing chamber.

[0016] Beneficial effects: The rigid transmission of the threaded rod and the nut seat, combined with the sliding guide of the limit rod, ensures that the horizontal movement trajectory of the seed mixing component is accurate and stable, avoiding mixing deviation; the translation motor drives the threaded rod to achieve uniform reciprocating motion, expanding the full coverage of the mixing blades on the seeds and eliminating the blind spots of mixing in the corners of the cavity; the mechanical limit structure simultaneously bears the stirring reaction force, ensuring the long-term reliability and durability of the translation component.

[0017] Furthermore, the seed mixing assembly includes teeth arranged in an annular manner on the outer side of the nut seat and a rotating disk sleeved on the nut seat, an annular groove is formed in the rotating disk, and a plurality of driving gears meshing with the teeth are arranged in an annular array in the annular groove; a plurality of rotating motors corresponding to the driving gears are arranged inside the rotating disk, and the output shafts of the rotating motors are coaxially fixedly connected to the driving gears;

[0018] A plurality of stirring blades are arranged in a circular array on the outer side of the rotating disk, and a cleaning plate is fixedly connected to the side of the stirring blades away from the rotating disk.

[0019] Beneficial Effects: Through a multi-point linkage design where teeth mesh with the drive gear, the rotating disc rotates synchronously during horizontal movement, creating a "revolution + rotation" compound mixing trajectory. This allows seeds to be fully tossed under the action of bidirectional centrifugal force, significantly improving mixing uniformity. The cleaning plate rotates synchronously with the mixing blades, scraping against the walls of the mixing chamber to promptly remove wet and sticky seeds or drug residue, preventing residue accumulation from affecting mixing balance or contaminating subsequent batches.

[0020] Furthermore, an exhaust channel communicating with the outside is opened on the side of the extrusion chamber away from the seed mixing chamber, and a first one-way valve is fixedly connected to the exhaust channel; a second one-way valve is installed inside the output gas channel.

[0021] Beneficial effects: The first one-way valve ensures that external air is inhaled to replenish air pressure when the extrusion block is reset, maintaining a stable airflow cycle; the second one-way valve prevents the compressed gas from flowing back, enhances the airflow intensity of the jet hole, and improves the cleaning and penetration efficiency.

[0022] Furthermore, a plurality of auxiliary stirring rods are fixedly connected through the stirring blades.

[0023] Beneficial effects: The auxiliary stirring rods form multi-level disturbances when the stirring blades rotate, enhancing the penetration between seed layers and breaking up deep seed clumps; the staggered distribution of the rods produces local turbulence, prolongs the contact time between the liquid medicine and the seeds, and promotes coating uniformity; at the same time, the auxiliary rods cooperate with the cleaning plate to stir the adhesions on the cavity wall and guide them to the air flow flushing path, thereby improving self-cleaning efficiency.

[0024] Furthermore, the medicine spraying components include a medicine storage box and a plurality of spray heads arranged at the bottom of the medicine storage box and connected to the interior of the medicine storage box. The two medicine storage boxes are respectively fixedly connected to both sides of the nut seat.

[0025] Beneficial effects: The spray assembly moves horizontally synchronously with the nut seat to achieve dynamic tracking spraying. The liquid coverage area is matched with the stirring path in real time, ensuring that the seeds are soaked at multiple angles during tumbling. The symmetrical layout of the nozzles on both sides forms a cross atomization belt, eliminating the blind area of ​​unidirectional spraying and improving the coating uniformity. At the same time, the integrated design reduces pipeline redundancy and reduces the resistance to liquid transportation.

[0026] Furthermore, the air jet holes are all arranged at an angle, and the air jet holes are close to one end of the seed mixing chamber and are located below the other end.

[0027] Beneficial Effects: The tilted jet holes create a downward jet flow that adheres closely to the cavity wall, enhancing the removal of adhered seeds. The tilted angle guides the airflow to create a swirl effect, extending the interaction time between the airflow and the seeds, improving the penetration of the liquid and the removal of impurities. The tilted jet holes also prevent the liquid from entering the holes.

[0028] Furthermore, a method for using the seed dressing device for Elymus spp. is as follows:

[0029] Step 1: After the Elymus spp. seeds are fed into the seed mixing chamber through the feed port, the translation motor is started to drive the threaded rod to rotate, so that the nut seat drives the rotating disk to move horizontally; at the same time, the rotation motor is started to drive the rotating disk and the stirring blade to rotate through the engagement of the drive gear and the teeth, thereby performing bidirectional stirring on the Elymus spp. seeds and driving the cleaning plate to scrape off the Elymus spp. seeds adhering to the side wall in the longitudinal direction of the seed mixing chamber;

[0030] Step 2: During the mixing process, the medicine storage box evenly sprays the liquid medicine into the seed mixing chamber through the nozzle; when the nut seat moves horizontally, the telescopic rod pushes the extrusion block in the moving direction to compress the air in the corresponding extrusion chamber. The air flow is obliquely ejected from the air jet hole through the air transmission channel, cleaning the Elymus seeds adhering to the two side walls in the width direction of the seed mixing chamber, and at the same time blowing away the seed pile and assisting the penetration of the liquid medicine;

[0031] Step 3: After the seed mixing is completed, the two arc-shaped baffles are slid apart, and the Elymus seeds fall into the seed discharge chamber and are discharged; the cleaning plate at the end of the mixing blade simultaneously scrapes off the seed residue adhering to the wall of the seed mixing chamber, and when the extrusion block is reset, external air is inhaled through the first one-way valve to supplement the air pressure.

[0032] Beneficial effects: Through the combined drive of horizontal movement and rotary stirring, two-way dynamic mixing of seeds in three-dimensional space is achieved, breaking through the limitations of traditional single-axis stirring and significantly improving the coating uniformity of Elymus villi seeds; the spraying and air flow injection are coordinated, and the atomized particles of the liquid medicine are forced to penetrate into the seed gaps under the disturbance of the air flow, completing the infiltration and impurity stripping simultaneously; the dual cleaning mechanism of mechanical scraping and air pressure flushing can remove the cavity wall adhesions in real time during the seed mixing process, avoid residual contamination and maintain stirring balance.

[0044] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] The following is further described in detail through specific implementation methods:

[0046] Example 1:

[0047] As attached Figure 1 As shown, a seed dressing device for Elymus spp. comprises a box body 1, a feed port 2 integrally formed on the top of the box body 1, and a controller (such as a PLC and a single-chip microcomputer). At the same time, since Elymus spp. seeds have thorns and low fluidity, the diameter of the feed port 2 is designed according to the characteristics of Elymus spp. seeds (for example, a diameter range of 100-150 mm) in actual application; Figure 2 and Figure 3 As shown, the interior of the box body 1 is arranged from top to bottom as a seed mixing chamber 4 and a seed discharge chamber 3, and a partition component is provided between the seed mixing chamber 4 and the seed discharge chamber 3 to physically divide the seed mixing chamber 4 and the seed discharge chamber 3, so as to facilitate the control of the two stages of seed mixing and seed discharge of the alkali grass seeds. Specifically, the partition component includes arc seats 6 symmetrically arranged on both sides of the interior of the box body 1, and the arc seats 6 are each provided with an arc chute on one side close to each other, and an arc baffle 10 is slidably fitted in the arc chute. At the same time, a number of electrically controlled telescopic frames electrically connected to the controller are installed in the arc chute, and one end of the electrically controlled telescopic frame is fixedly connected to the inner wall of the arc chute with screws, and the other end of the electrically controlled telescopic frame is fixedly connected to the arc baffle 10 with screws, so that the opening / closing of the two arc baffles 10 is realized by the extension and contraction of the electrically controlled telescopic frame, that is, the two stages of seed mixing and seed discharge of the alkali grass seeds are accurately controlled. At the same time, a number of through holes are opened on the surface of the arc-shaped baffle 10, which can filter out excess liquid medicine during the seed mixing process, so that the excess liquid medicine flows into the seed cavity 3 through the through holes for temporary storage or discharge, thereby avoiding excessive infiltration of seeds and resulting in adhesion; at the same time, the through holes form microchannels to assist the airflow to penetrate the seed layer and accelerate the uniform adsorption of the liquid medicine.

[0048] For the seed dressing of alkali grass seeds, stirring and spraying of medicines are inevitable (the conventional operation of seed dressing of alkali grass seeds). However, due to the characteristics of alkali grass seeds (small monomer mass and long awns on the surface), when the seeds are mixed and stirred in the existing mixing and stirring, after the mixed medicine is mixed, it is very easy to adhere to the surroundings of the stirring chamber, and it is also easy to form lumps, which affects the mixing efficiency of the alkali grass seeds and the medicine solution.

[0049] Therefore, a seed mixing component for stirring Elymus seeds is provided inside the seed mixing chamber 4, and the seed mixing component is threadedly connected to a translation component for driving the seed mixing component to move horizontally. The seed mixing component is driven to move back and forth horizontally along the seed mixing chamber 4 by the translation component, thereby expanding the stirring coverage range and avoiding seed accumulation. At the same time, the seed mixing component rotates while moving, exerting multi-directional shear force on the seeds and improving mixing uniformity.

[0050] Specifically, combined Figure 3 and Figure 6 As shown, the translation assembly includes a translation motor 16 arranged in the box body 1, and the output shaft of the translation motor 16 is fixedly connected with a threaded rod 8 by a coaxial bolt. The threaded rod 8 extends into the seed mixing chamber 4 away from one end of the translation motor 16 and is rotatably connected to the inner wall of the seed mixing chamber 4. A nut seat 11 is threadedly connected to the threaded rod 8, and a limit rod 9 is symmetrically slidably fitted on the nut seat 11. Both ends of the limit rod 9 are respectively fixedly connected to the two inner walls of the seed mixing chamber 4 with screws.

[0051] Specifically, combined Figure 3 and Figure 7 As shown, the seed mixing assembly includes teeth 21 arranged in an annular manner on the outside of the nut seat 11 and a rotating disk 12 arranged in an annular array on the nut seat 11. The rotating disk 12 has an annular groove, and a plurality of drive gears 22 meshing with the teeth 21 are arranged in an annular array in the annular groove; a plurality of rotating motors corresponding to the drive gears 22 are arranged inside the rotating disk 12, and the output shafts 23 of the rotating motors are all coaxially fixedly connected to the drive gears 22; a plurality of stirring blades 15 are arranged in an annular array on the outside of the rotating disk 12, and a cleaning plate 14 is fixedly connected to the side of the stirring blades 15 away from the rotating disk 12. At the same time, a plurality of auxiliary stirring rods 13 are fixedly connected to the stirring blades 15. When the stirring blades 15 rotate, the auxiliary stirring rods 13 form multi-level disturbances, enhance the penetration force between the seed layers, and break up deep seed clumps; the staggered distribution of the rods produces local turbulence, prolongs the contact time between the liquid medicine and the seeds, and promotes coating uniformity; at the same time, the auxiliary rods cooperate with the cleaning plate 14 to stir the adhesions on the cavity wall and guide them to the air flow flushing path, thereby improving self-cleaning efficiency.

[0052] The translation motor 16 and the rotation motor are both electrically connected to the controller.

[0053] For spraying of medicine for seed dressing, spraying components for spraying liquid medicine are installed on both sides of the nut seat 11, combined with Figure 3 and Figure 4 As shown, the medicine spraying assembly includes a medicine storage box and a plurality of spray heads arranged at the bottom of the medicine storage box and communicating with the interior of the medicine storage box. The two medicine storage boxes are fixedly connected to both sides of the nut seat 11 by screws.

[0054] When the rotating disk 12 and the nut seat 11 reciprocate left and right (during seed dressing), the special feature is that, combined with Figure 5 、 Figure 6and Figure 7 As shown, a plurality of extrusion chambers 18 are symmetrically arranged on both sides of the length direction of the housing 1, and an extrusion block 19 is movably fitted in each of the extrusion chambers 18. The extrusion block 19 is screwed fixedly connected to the telescopic rod 7 on the side close to the seed mixing chamber 4. The end of the telescopic rod 7 away from the extrusion block 19 extends into the seed mixing chamber 4 and is screwed fixedly connected to the nut seat 11. This ensures that when the nut seat 11 approaches the extrusion chamber 18 on one side, the telescopic rod 7 on that side can contract and push the corresponding extrusion block 19, while the telescopic rod 7 on the other side stretches to match the movement distance, thereby ensuring that the extrusion blocks 19 on both sides of the housing 1 can slide alternately during the reciprocating motion of the nut seat 11. A plurality of air supply channels 17 are opened at the end of the extrusion chamber 18 away from the seed mixing chamber 4, and a plurality of air injection holes 5 are opened on both sides of the width direction of the mixing chamber. The air supply channels 17 are connected to the air injection holes 5. The horizontal reciprocating motion of the nut seat 11 directly drives the extrusion blocks 19 on both sides through the telescopic rod 7 to squeeze the air in the corresponding extrusion chamber 18. The compressed air is ejected at high speed from the air jet hole 5 through the air transmission channel 17, cleaning the Elymus seeds adhering to the left and right side walls of the seed mixing chamber 4 (adhering seeds or liquid residue are peeled off, and the cleaning plate 14 simultaneously scrapes the cavity wall to avoid residue). At the same time, the stirring blade 15 is pushed toward the left and right side walls of the seed mixing chamber 4 and blown toward the middle of the seed mixing chamber 4, thereby blowing away the Elymus seeds clumps gathered on the left and right side walls of the seed mixing chamber 4. Moreover, when the liquid medicine is sprayed, as the nozzle approaches the air jet hole 5, the airflow from the air jet hole 5 will promote the atomization and diffusion of the liquid medicine, promoting the uniform distribution of the medicine on the surface of the Elymus seeds.

[0055] Since the liquid medicine may enter the gas delivery channel 17 through the injection hole 5 when spraying, affecting the injection efficiency, Figure 5 As shown, the air-jet holes 5 are all arranged at an angle, and the air-jet holes 5 are close to one end of the seed-dressing chamber 4 and are located below the other end.

[0056] Because the extrusion block 19 slides back and forth in the extrusion chamber 18, when the extrusion block 19 compresses the air in the extrusion chamber 18 and then resets, a negative pressure is generated at the air jet hole 5, and some Elymus seeds are adsorbed to block the air jet hole 5. Therefore, Figure 6 and Figure 7 As shown, an exhaust passage 20 is formed on the side of the extrusion chamber 18 facing away from the seed mixing chamber 4, communicating with the outside world. A first one-way valve is bonded to each exhaust passage 20, and a second one-way valve is bonded to each outlet passage. When air is released from the air jet 5, the first one-way valve closes and the second one-way valve opens. When the extrusion block 19 returns to its original position, the first one-way valve opens and the second one-way valve closes.

[0057] Example 2:

[0058] The difference from the above embodiment is that the method for using the seed dressing device for Elymus spp. comprises the following specific steps:

[0059] Step 1: After the Elymus seeds are put into the seed mixing chamber 4 through the feed port 2, the translation motor 16 is started to drive the threaded rod 8 to rotate, so that the nut seat 11 drives the rotating disk 12 to move horizontally; at the same time, the rotation motor is started to drive the rotating disk 12 and the stirring blade 15 to rotate by engaging the driving gear 22 with the teeth 21, thereby performing bidirectional stirring on the Elymus seeds and driving the cleaning plate 14 to scrape off the Elymus seeds adhering to the side wall of the seed mixing chamber 4 in the longitudinal direction;

[0060] Step 2: During the stirring process, the medicine storage box evenly sprays the liquid medicine into the seed mixing chamber 4 through the nozzle; when the nut seat 11 moves horizontally, the telescopic rod 7 pushes the extrusion block 19 in the moving direction to compress the air in the corresponding extrusion chamber 18, and the air flow is obliquely ejected from the air jet hole 5 through the air transmission channel 17, cleaning the Elymus seeds adhering to the two side walls in the width direction of the seed mixing chamber 4, and at the same time blowing away the seed pile and assisting the penetration of the liquid medicine;

[0061] Step 3: After the seed mixing is completed, the two arc-shaped baffles 10 are slid apart, and the Elymus seeds fall into the seed discharge cavity 3 and are discharged; the cleaning plate 14 at the end of the stirring blade 15 simultaneously scrapes off the seed residue adhering to the wall of the seed mixing cavity 4, and when the squeezing block 19 is reset, external air is inhaled through the first one-way valve to supplement the air pressure.

[0062] 1. Experimental subjects:

[0063] Seed type: Elymus seeds (specifically Elymus sibiricus), with long awns on the surface, 1000-grain weight of approximately 3.5g, and moisture content ≤12%.

[0064] Agent type: The coating agent is methyl thiophanate suspension (concentration 10%), with a viscosity of 50-60 mPa·s (25°C).

[0065] Equipment for the control group: traditional vertical mixer (paddle stirring, without airflow assistance and cavity wall cleaning function).

[0066] 2. Experimental results:

[0067] Table 1 - Experimental data of seed dressing device for Elymus spp.

[0068]

[0069] As shown in Table 1, this solution significantly optimizes seed mixing efficiency and coating quality through the coordinated design of mechanical and airflow. Experiments show that its mixing uniformity coefficient of variation (CV) is 8.7% (the CV is the ratio of the standard deviation (S) of a component's content in a mixture to its mean (X), expressed as a percentage. It reflects the dispersion of the distribution of each component in the mixture; smaller CV values ​​indicate higher mixing uniformity). This is a 65.6% reduction compared to traditional mixing (25.3%). This is attributed to the multi-directional shear force generated by the horizontal movement of the bidirectional mixing blades and the turbulent disturbance of the auxiliary stirring rods, combined with the high-speed airflow (12 m / s) from the air jets penetrating the seed layer, which increases the agglomerate breakup rate to 97%. Through the synergistic effect of scraping with a cleaning plate and airflow from inclined air jets (atomized particle size ≤ 50 μm), the device reduces the cavity wall residue rate to 2.1% and increases the liquid utilization rate to 95%. The single-pass processing time was shortened to 28 minutes (a 37.8% decrease), with an hourly processing capacity of 10.2 kg, resulting in a 52.2% improvement in overall efficiency. Despite a 60% increase in energy consumption (0.8 kW h / batch), the device demonstrated outstanding stability and self-cleaning capabilities. After 10 consecutive runs, the mixing uniformity fluctuation was ≤1.2%, with no mechanical failures. The one-way valve design of the air jet effectively prevents clogging. This device addresses the problem of long-awned Elymus seeds, which tend to stick and cause uneven mixing, providing a reliable solution for large-scale, efficient seed mixing.

[0070] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
