Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and more specifically, to a corn seed coating and pelleting device. Background Art

[0002] Coating corn seeds is a technology widely used in agricultural production. Its main purpose is to wrap a protective film containing micronutrients and plant growth regulators on the seed surface to improve the germination rate of seeds, promote seedling growth, prevent pests and diseases, and reduce environmental pollution.

[0003] There is a prior art of a drum spiral type seed pelleting and coating device and its control method with the application number CN202210545140.1. This patent document discloses a method of spraying coating powder on the surface of wet seeds and ensuring that the coating powder adheres to the seed surface through continuous turning. Specifically, a spiral structure is used to make the seeds rotate and tumble rapidly in the rotating body, and the seeds move from one side of the rotating body to the other during the processing. After the seeds pass through the liquid atomization area formed by the atomizer and the powder supply area formed by the seed material supply component, each time the wetted seeds obtain the powder, rolling is used to achieve the adhesion of the powder on the seed surface, thereby realizing the pelleting and coating of the seeds. Finally, the side wall of the rotating body is heated by a drying device, and the rounded seeds in the previous step are dried through heat conduction to finally obtain the finished pelleted seeds.

[0004] However, when using the technical solution in the above patent document, in order to ensure that the coating powder can smoothly adhere to the outer surface of the seeds, the outer surface of the seeds needs to be fully wetted. This requires subsequent steps to fully dry the seeds to avoid rotting during storage. However, after the coating powder forms a thin film layer on the seed surface, the moisture will be sealed between the outer surface of the seed and the thin film layer, affecting the seed drying efficiency and prolonging the drying time. The long-term drying effect will have an adverse impact on the subsequent germination and growth of the seeds. Therefore, the present application provides a corn seed coating and pelleting device. Summary of the Invention

[0005] In order to solve the above deficiencies in the prior art, the purpose of the present invention is to provide a corn seed coating and pelleting device. This device does not require long-term drying of the seeds, effectively avoiding the rotting phenomenon caused by the penetration of the wet moisture on the seed surface into the seed interior. On this basis, a regularly shaped circular coating layer is constructed on the outside of the seeds. When using a seeder, the circular coating layer can ensure more uniform distribution of the seeds during sowing, achieve a balanced seeding density, and ensure the healthy growth of crops throughout the growth cycle.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0007] A corn seed coating and pelleting device is provided, including a bearing platform. A plurality of sizing accommodating tiles for accommodating corn seeds and seed coating materials are arranged on the bearing platform. A synchronous pressing platform is slidably installed on the upper side of the bearing platform, and a synchronous lifting platform is slidably installed on the lower side of the bearing platform. A sizing pressing pestle is arranged on the synchronous pressing platform. An arc edge I and an arc edge II are arranged at the bottom of the sizing pressing pestle. The arc edge I can be attached to the upper side surface of the sizing accommodating tile, and a spherical cavity can be formed between the arc edge II and the inner side surface of the sizing accommodating tile.

[0008] Furthermore, a T-shaped seat is arranged on the synchronous lifting platform, and a plurality of top columns capable of passing through the bottom of the sizing accommodating tile are fixedly installed on the T-shaped seat. The top columns are made of rubber material, and the tops of the plurality of top columns can be simultaneously attached to the inner side surface of the sizing accommodating tile to prevent the seed coating material from leaking at the bottom position of the sizing accommodating tile.

[0009] Furthermore, a cover cylinder is slidably installed on the outer side of the sizing pressing pestle. A sealing ring is fixedly installed on the inner side of the cover cylinder. The inner side surface of the sealing ring is tightly connected to the outer side surface of the sizing pressing pestle. A tension spring is detachably and fixedly installed between the sizing pressing pestle and the cover cylinder. Sleeve rings are arranged at both ends of the tension spring, and the two sleeve rings are respectively detachably and fixedly connected to the sizing pressing pestle and the cover cylinder. A magnetic attraction ring is detachably and fixedly installed on the bearing platform, and the magnetic attraction ring is magnetically adsorbed and coupled with an electromagnet II embedded at the bottom of the cover cylinder.

[0010] Furthermore, a fitting arm is fixedly installed on one side of the bearing platform. The fitting arm is slidably connected to a horizontal axis. A transmission seat is fixedly installed on the other side of the bearing platform. The transmission seat is in threaded transmission connection with a lead screw. The ends of the horizontal axis and the lead screw are connected together through a main base. The lead screw is rotatably connected to the main base, and a servo motor for driving the lead screw to rotate is installed on the main base.

[0011] Furthermore, a secondary base I is arranged between the two main bases. A feeder is fixedly installed on the secondary base I. A feed pipe is fixedly installed and communicated at the top of the feeder. A fixed baffle is fixedly installed on one side of the bottom of the feeder, and a movable baffle is slidably installed on the other side of the bottom of the feeder. A variable-volume discharge channel is formed by the inner side surfaces of the bottom of the feeder, the fixed baffle, and the movable baffle. A first linear electric cylinder for driving the movable baffle to move is installed on the inner side of the feeder.

[0012] Further, an arc-shaped groove is provided at the bottom of the chimeric arm. The arc-shaped groove is slidably connected to the horizontal axis. A plug is slidably installed on the bearing platform. The tightening post at the end of the plug can penetrate through the round hole on the transmission seat and press tightly against the outer side of the lead screw. The radian center of the side wall of the arc-shaped groove and the rotation center of the lead screw are on the same virtual axis. A plurality of electromagnets I are arranged on the lower side of the top of the arc-shaped groove. The electromagnets I are magnetically adsorbed and coupled to the horizontal axis.

[0013] Further, the sizing accommodating tile and the T-shaped seat are respectively detachably and fixedly installed on the bearing platform and the synchronous lifting platform. A jack I for the top post to penetrate is provided on the bearing platform. The top edge of the sizing accommodating tile abuts against the lower side of the magnetic attraction ring.

[0014] Further, a convex rib is integrally formed at the end of the synchronous lifting platform. The convex rib is inserted and slidably connected to the limiting groove at the bottom of the bearing platform.

[0015] Further, a driving and controlling arm is fixedly installed on the side of the synchronous lifting platform. The driving and controlling arm is inserted and slidably connected to the sliding opening on the bearing platform. A third linear electric cylinder is arranged at the bottom of the bearing platform. The movable end of the third linear electric cylinder is inserted into the jack II at the bottom of the bearing platform and is detachably and fixedly connected to the driving and controlling arm.

[0016] Further, the inner diameter size of the magnetic attraction ring is smaller than the inner diameter size of the bottom of the cover cylinder. The outer edge of the bottom of the sizing pressing pestle abuts against both the inner side of the magnetic attraction ring and the inner edge of the top of the magnetic attraction ring simultaneously.

[0017] Further, a second linear electric cylinder for driving the plug to slide is installed in the bearing platform. A slot is arranged in the transmission seat. The slot is inserted and slidably connected to the end of the plug.

[0018] Further, a polygonal connecting seat is fixedly installed on the movable end of the second linear electric cylinder. The polygonal connecting seat is inserted and connected to the plug and the position is locked by a fastener.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. For the corn seed coating and pelleting equipment of the present invention example, the seed coating material is formed in the spherical cavity between the arc edge II and the inner side of the sizing accommodating tile. The formed seed coating material is circular. When using a seeding machine for seeding operation, the circular seed coating layer makes the corn seeds easier to roll and discharge during seeding, reduces blockage while ensuring single-seed seeding, accurately controls the planting density, avoids waste of seeds, has high seeding uniformity, provides convenience for subsequent field management, so as to more precisely control experimental variables, improves the accuracy and reliability of experimental results, and provides more effective data support for the cultivation of excellent corn varieties.

[0021] 2. For the corn seed coating and pelleting equipment of the present invention example, after the corn seeds are automatically positioned at the center of the sizing receiving tile, the corn seeds maintain a constant distance from the inner sides of the sizing receiving tile and the sizing pressing pestle. As a result, the coated and pelletized corn seeds are in the middle position of the round seed coating layer, and the seed coating has good protective performance for the corn seeds, avoiding damage to the corn seeds caused by sowing equipment.

[0022] 3. For the corn seed coating and pelleting equipment of the present invention example, when the sizing pressing pestle squeezes the seed coating material in the sizing receiving tile, the seed coating material at the top edge of the sizing receiving tile is first restricted by the inner side of the magnetic attraction ring. And because the outer edge at the bottom of the sizing pressing pestle can simultaneously abut against the inner side of the magnetic attraction ring and the top inner edge of the magnetic attraction ring, forming a zigzag contact surface. During the process of the sizing pressing pestle performing multiple squeezes on the coating material, using this zigzag contact surface, the seed coating material is gradually guided towards the inner middle area of the sizing receiving tile. As the squeezing operation continues, the seed coating material is effectively enclosed between the sizing pressing pestle and the sizing receiving tile. During this process, the gap between the magnetic attraction ring and the cover cylinder will not become a channel for the leakage of the seed coating material, ensuring the stability of the seed coating material during the pelleting process, guaranteeing the quality of the seed coating and pelleting, and meeting the requirements for the stability of the coating and pelleting process during the seed processing.

[0023] 4. For the corn seed coating and pelleting equipment of the present invention example, the cover cylinder is used to shield the seed coating material stored in the sizing receiving tile, avoiding splashing everywhere during the process of the sizing pressing pestle performing multiple squeezes on this part of the seed coating material, ensuring that the seed coating material is fully filled at various positions inside the spherical cavity, thereby constructing a regularly shaped round seed coating layer on the outside of the corn seeds, increasing the effect of the seed coating layer in protecting the corn seeds, improving the seed germination rate, and enhancing the stress resistance of the seeds.

[0024] 5. For the corn seed coating and pelleting equipment of the present invention example, the sizing receiving tile and the T-shaped seat are respectively detachably and fixedly installed on the bearing platform and the synchronous lifting platform. There are multiple jacks Ⅰ on the bearing platform for the top columns to penetrate simultaneously. The top edge of the sizing receiving tile abuts against the lower side of the magnetic attraction ring; by disassembling and replacing the sizing receiving tiles, T-shaped seats and sizing pressing pestles of different size types, the internal size of the spherical cavity can be changed, so as to adapt to the coating and pelleting treatment of different types of plant seeds, and the equipment has good general applicability.

[0045] Embodiment 1:

[0046] As Figure 1 shown, this embodiment provides a corn seed coating and pelleting device, including a carrier table 21. A plurality of sizing accommodation tiles 26 for accommodating corn seeds 1 and seed coating materials are arranged on the carrier table 21. A synchronous pressing table 43 is slidably installed on the upper side of the carrier table 21, and a synchronous lifting table 31 is slidably installed on the lower side of the carrier table 21. A convex rib is integrally formed at the end of the synchronous lifting table 31, and the convex rib is inserted and slidably connected with the limiting groove 215 at the bottom of the carrier table 21, playing a role of limiting and guiding; a sizing pressing pestle 44 is detachably and fixedly installed on the synchronous pressing table 43. An arc edge I 441 and an arc edge II 442 are arranged at the bottom of the sizing pressing pestle 44. The arc edge I 441 can be attached to the upper side surface of the sizing accommodation tile 26, and a spherical cavity can be formed between the arc edge II 442 and the inner side surface of the sizing accommodation tile 26.

[0047] The seed coating materials used in this application include seed coating agents and hydrolyzable viscous materials; the hydrolyzable viscous materials can use natural materials such as pectin, viscose fiber, and chitosan, or can also use water-based pressure-sensitive adhesive JS1050-W and biodegradable pressure-sensitive adhesive; under the action of multiple squeezes of the sizing pressing pestle 44, the seed coating materials are formed in the spherical cavity between the arc edge II 442 and the inner side surface of the sizing accommodation tile 26;

[0048] The formed seed coating materials are circular. When using a seeder for sowing operations, the circular seed coating layer makes the corn seeds 1 roll and seed metering more easily during sowing, reducing blockage while ensuring single-seed sowing, precisely controlling the planting density, avoiding waste of seeds, having high sowing uniformity, providing convenience for subsequent field management, so as to more accurately control experimental variables, improving the accuracy and reliability of experimental results, and providing more effective data support for the cultivation of excellent corn varieties.

[0049] Wherein, Teflon coatings are provided on the outer sides of the sizing receiving tile 26 and the sizing pressing pestle 44 to prevent the seed coating material from adhering to the outer surfaces of the sizing receiving tile 26 and the sizing pressing pestle 44, which may affect the seed coat forming of the corn seeds 1.

[0050] As Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, a T-shaped seat 34 is arranged on the synchronous lifting platform 31, and a plurality of ejector pins 35 capable of penetrating the bottom of the sizing receiving tile 26 are fixedly installed on the T-shaped seat 34. The ejector pins 35 are made of rubber, and the tops of the plurality of ejector pins 35 can simultaneously fit against the inner side surface of the sizing receiving tile 26 to prevent the seed coating material from leaking at the bottom position of the sizing receiving tile 26.

[0051] The specific details of using the corn seed coating and pelleting equipment of the present application are as follows:

[0052] 1. Automatically positioning the corn seeds 1 at the center of the sizing receiving tile 26;

[0053] First, manually or using a commercially available pick-and-place manipulator product, the corn seeds 1 are put into the sizing receiving tile 26. Since a spherical groove is provided inside the sizing receiving tile 26, the corn seeds 1 automatically slide into the middle side at the bottom of the sizing receiving tile 26.

[0054] After that, the synchronous lifting platform 31 is controlled to move vertically upward, driving the plurality of ejector pins 35 to rise at the middle side of the bottom of the sizing receiving tile 26. Since the ejector pins 35 at the edge are long and the ejector pins 35 in the middle are short, the plurality of ejector pins 35 are used to stably lift the corn seeds 1 to automatically position the corn seeds 1 at the center of the sizing receiving tile 26.

[0055] 2. Forming a circular seed coat layer on the outside of the corn seeds 1 with the seed coating material;

[0056] First, manually put the seed coating material into the sizing receiving tile 26 and fill it up, and apply the seed coating material between the outside of the corn seeds 1 and the plurality of ejector pins 35. The ejector pins 35 and the seed coating material located under the corn seeds 1 are used to jointly lift the corn seeds 1.

[0057] After that, control the synchronous pressing platform 43 to move downward, driving multiple sizing pressing rods 44 to extrude the seed coating material in the sizing receiving tile 26. Since a viscous material is used inside the seed coating material, under the action of the sizing pressing rods 44, the seed coating material is compacted on the outer side of the corn seed 1 in the spherical cavity. During this process, by slowly controlling the synchronous lifting platform 31 to move downward, the seed coating material at the bottom of the corn seed 1 is made to fully abut against the corn seed 1, avoiding the formation of overly deep concave holes on the outer seed coat of the corn seed 1 after coating and pelleting due to the presence of multiple ejector posts 35, and having a good effect on preventing pests and diseases.

[0058] Finally, manually or using a pick-and-place manipulator product on the market, pick up and remove the corn seeds 1 after coating and pelleting. Since the seed coat is circular under the action of the spherical cavity, and the circular seed coat can ensure more uniform distribution of seeds during sowing, thus achieving a balanced seeding density and ensuring the healthy growth of crops throughout the growth cycle.

[0059] In the above step one, after the corn seed 1 is automatically positioned at the center of the sizing receiving tile 26, the corn seed 1 maintains a constant distance from the inner sides of the sizing receiving tile 26 and the sizing pressing rods 44. Thus, the coated and pelletized corn seed 1 is located at the central position of the circular seed coat, and the seed coat has good protection performance for the corn seed 1, avoiding damage to the corn seed 1 by the sowing equipment.

[0060] In the above step two, the thicker seed coat on the outer side of the corn seed 1 can be heated by installing electric heating components inside the carrier platform 21 and the sizing pressing rods 44 to improve its forming effect. Since the seed coat has a certain thickness and a viscous material is used inside the seed coating material to replace the atomized water liquid used in the prior art, on the basis of ensuring the uniform formation of the seed coat, there is no need to dry the moisture between the outer surface of the seed and the seed coat for a long time, avoiding the rotting phenomenon caused by the penetration of the moist moisture on the seed surface into the seed interior, enabling the seeds to germinate smoothly and avoiding adverse effects on the corn seed 1.

[0061] Such as Figure 1 、 Figure 2 and Figure 4As shown, one side of the carrier table 21 is fixedly installed with a fitting arm 22. The fitting arm 22 is slidably connected to the horizontal shaft 12. The other side of the carrier table 21 is fixedly installed with a transmission seat 23. The transmission seat 23 is in threaded transmission connection with the lead screw 13. The ends of the horizontal shaft 12 and the lead screw 13 are connected together through the main base 11. The lead screw 13 is rotatably connected to the main base 11. A servo motor for driving the lead screw 13 to rotate is installed on the main base 11. Start the servo motor, control the rotation of the lead screw 13, and drive the carrier table 21 to move horizontally on the horizontal shaft 12 by means of the threaded transmission connection between the lead screw 13 and the transmission seat 23. Through the vibration generated by controlling the horizontal reciprocating movement of the carrier table 21, the seed coating material is evenly filled inside the constant-diameter accommodating tile 26 and between multiple top columns 35.

[0062] In order to increase the general use effect of the equipment, such as Figure 5 As shown, the constant-diameter accommodating tile 26 and the T-shaped seat 34 are respectively detachably and fixedly installed on the carrier table 21 and the synchronous lifting table 31. Multiple jacks Ⅰ 212 for the top columns 35 to penetrate simultaneously are provided on the carrier table 21. The top edge of the constant-diameter accommodating tile 26 abuts against the lower side of the magnetic attraction ring 27. By disassembling and replacing the constant-diameter accommodating tiles 26, T-shaped seats 34 and constant-diameter pressing pestles 44 of different size types, the internal size of the spherical cavity can be changed, so as to adapt to the coating and pelletizing treatment of different types of plant seeds, and the general use effect of the equipment is good.

[0063] The moving mode of the synchronous lifting table 31 in this application is as follows: As Figure 7 、 Figure 8 and Figure 11 As shown, a driving and controlling arm 32 is fixedly installed on the side of the synchronous lifting table 31. The driving and controlling arm 32 is in fitting and sliding connection with the sliding opening 214 on the carrier table 21. A third linear electric cylinder 33 is arranged at the bottom of the carrier table 21. The movable end of the third linear electric cylinder 33 is inserted into the jack Ⅱ 213 at the bottom of the carrier table 21 and is detachably and fixedly connected to the driving and controlling arm 32. Start multiple third linear electric cylinders 33 synchronously, drive multiple driving and controlling arms 32 to slide vertically in the sliding opening 214, and control the synchronous lifting table 31 to move vertically relative to the carrier table 21.

[0064] The moving mode of the synchronous pressing table 43 in this application is as follows: As Figure 1 and Figure 2 As shown, multiple fourth linear electric cylinders 42 are installed on the synchronous pressing table 43. The movable ends of the fourth linear electric cylinders 42 are connected to the synchronous pressing table 43, and the fixed ends of the fourth linear electric cylinders 42 are connected to the secondary base Ⅱ 41. Start multiple fourth linear electric cylinders 42 synchronously, and drive the synchronous pressing table 43 to move vertically relative to the carrier table 21.

[0065] Embodiment 2:

[0066] The features that are the same as those in the first embodiment will not be described in detail. The differences between this embodiment and the first embodiment are as follows: As Figure 5 and Figure 6 shown, in this embodiment, a cover cylinder 45 is slidably installed on the outer side of the sizing pressing pestle 44. A sealing ring 443 is fixedly installed on the inner side of the cover cylinder 45. The inner side surface of the sealing ring 443 is tightly connected to the outer side surface of the sizing pressing pestle 44. A tension spring 46 is detachably and fixedly installed between the sizing pressing pestle 44 and the cover cylinder 45. Both ends of the tension spring 46 are provided with collar rings, and the two collar rings are respectively detachably and fixedly connected to the sizing pressing pestle 44 and the cover cylinder 45. A magnetic attraction ring 27 is detachably and fixedly installed on the bearing platform 21. The magnetic attraction ring 27 is magnetically adsorbed and coupled with an electromagnet II embedded in the bottom of the cover cylinder 45.

[0067] Under the action of the tension spring 46, the cover cylinder 45 extends downward on the outer side of the sizing pressing pestle 44. During the downward movement of the synchronous pressing table 43, the cover cylinder 45 abuts against the magnetic attraction ring 27 before the sizing pressing pestle 44. Subsequently, the electromagnet II at the bottom of the cover cylinder 45 is activated, so that the electromagnet II and the magnetic attraction ring 27 are tightly pressed against each other and fit together. In this state, the cover cylinder 45 is used to block the seed coating material stored in the sizing receiving tile 26, avoiding splashing everywhere during the process of the sizing pressing pestle 44 squeezing this part of the seed coating material multiple times, ensuring that the seed coating material is fully filled at various positions inside the spherical cavity, thereby constructing a circular seed coating layer with a regular shape on the outer side of the corn seed 1, increasing the effect of the seed coating layer in protecting the corn seed, improving the seed germination rate, and enhancing the stress resistance of the seed.

[0068] As Figure 5 shown, the inner diameter dimension of the magnetic attraction ring 27 is smaller than the inner diameter dimension of the bottom of the cover cylinder 45, so that when the cover cylinder 45 is slightly offset relative to the magnetic attraction ring 27 due to uncertain factors such as external force, the cover cylinder 45 can easily return to its original position by virtue of the space around the magnetic attraction ring 27.

[0069] During the process of implementing the above scheme of this embodiment, when controlling the sizing pressing pestle 44 to squeeze the seed coating material in the sizing receiving tile 26, the seed coating material at the top edge of the sizing receiving tile 26 is first restricted by the inner side surface of the magnetic attraction ring 27, and since the outer edge of the bottom of the sizing pressing pestle 44 can simultaneously abut against the inner side surface of the magnetic attraction ring 27 and the inner edge of the top of the magnetic attraction ring 27, a zigzag contact surface is formed;

[0070] During the process of the sizing pressing pestle 44 extruding the coating material multiple times, by utilizing the tortuous contact surface, the seed coating material is gradually guided towards the inner middle region of the sizing receiving tile 26. As the extrusion operation continues, the seed coating material is effectively enclosed between the sizing pressing pestle 44 and the sizing receiving tile 26. During this process, the gap between the magnetic attraction ring 27 and the cover cylinder 45 will not become a channel for the leakage of the seed coating material, ensuring the stability of the seed coating material during the pelleting process, guaranteeing the quality of the seed coating pelleting, and meeting the requirements for the stability of the coating pelleting process during the seed processing.

[0071] Embodiment Three:

[0072] The features identical to those in Embodiment One will not be described in detail. The different solutions in this embodiment from Embodiment One are as follows: As Figure 1 , Figure 2 and Figure 3 shown, in this embodiment, at least two sub-bases Ⅰ 14 are arranged between the two main bases 11. A feeder 15 is fixedly installed on each sub-base Ⅰ 14. A feed pipe 151 is fixedly connected to the top of the feeder 15. A fixed baffle 16 is fixedly installed on one side of the bottom of the feeder 15, and a movable baffle 17 is slidably installed on the other side of the bottom of the feeder 15. The bottoms of the fixed baffle 16 and the movable baffle 17 can respectively abut against the upper side surface of the carrier table 21.

[0073] Among them, a variable-volume discharging channel is formed by the inner side surfaces of the bottoms of the feeder 15, the fixed baffle 16, and the movable baffle 17. A first linear electric cylinder 19 for driving the movable baffle 17 to move is installed inside the feeder 15.

[0074] When the ends of the fixed baffle 16 and the movable baffle 17 are in contact with each other, the width of the variable-volume discharging channel is zero, and the seed coating material enters between the feeder 15, the fixed baffle 16, and the movable baffle 17 through the feed pipe 151 for storage.

[0075] When it is necessary to add the seed coating material into the sizing receiving tile 26: Start the first linear electric cylinder 19 to adjust the spacing of the variable-volume discharging channel, so that the seed coating material is discharged from the variable-volume discharging channel. At the same time, control the horizontal movement of the carrier table 21, and the bottoms of the fixed baffle 16 and the movable baffle 17 scrape the seed coating material discharged onto the carrier table 21, so that the seed coating material can evenly fill into the multiple sizing receiving tiles 26. Compared with the method of manually adding the seed coating material in Embodiment One, using the above solution in this embodiment can effectively improve the use efficiency of the equipment.

[0076] Embodiment Four:

[0077] The features that are the same as those in Embodiment 3 will not be described in detail again. The differences between this embodiment and Embodiment 3 are as follows: As Figure 1 , Figure 3 and Figure 10 show, in this embodiment, a sealing edge 211 is fixedly installed at the top of the bearing table 21. The sealing edge 211 is annular and surrounds the peripheral side of the top of the bearing table 21; sealing strips 18 are fixedly installed at the bottoms of the fixed baffle 16 and the movable baffle 17; the width of the sealing edge 211 corresponds to the length of the sealing strip 18, and the lower side surface of the sealing strip 18 is in abutting fit with the upper side surface of the sealing edge 211, so that the seed coating material sliding out between the fixed baffle 16 and the movable baffle 17 is restricted to the area inside the sealing edge 211, avoiding waste caused by the scattered seed coating material.

[0078] Embodiment 5:

[0079] The features that are the same as those in Embodiment 1 will not be described in detail again. The differences between this embodiment and Embodiment 1 are as follows: As Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 9 show, in this embodiment, an arc-shaped groove 221 is provided at the bottom of the fitting arm 22. The arc-shaped groove 221 is slidably connected to the horizontal shaft 12. A plug 24 is slidably installed on the bearing table 21. The tightening post 241 at the end of the plug 24 can penetrate through the circular hole 231 on the transmission seat 23 and abut against the outer side surface of the lead screw 13; the center of the radian of the side wall of the arc-shaped groove 221 and the rotation center of the lead screw 13 are on the same virtual axis.

[0080] As Figure 4 shows, a plurality of electromagnets I 222 are provided on the lower side of the top of the arc-shaped groove 221. The electromagnets I 222 are magnetically adsorbed and coupled to the horizontal shaft 12. When it is necessary to control the horizontal movement of the bearing table 21, the horizontal shaft 12 is stably inserted into the arc-shaped groove 221 by using the magnetic adsorption between the electromagnets I 222 and the horizontal shaft 12.

[0081] Control the sliding of the plug 24 on the bearing table 21 so that the tightening post 241 at the end of the plug 24 abuts against the outer side surface of the lead screw 13; then start the servo motor to drive the lead screw 13, the bearing table 21 and the transmission seat 23 to turn together, so that the arc-shaped groove 221 is disengaged from the horizontal shaft 12, and a plurality of coated and pelletized corn seeds 1 on the bearing table 21 are poured out, reducing the workload of manually picking up the coated and pelletized corn seeds 1 and improving the automation operation efficiency of the entire equipment in the seed treatment process.

[0082] The moving control mode of the plug 24 is as follows: As Figure 9 , Figure 10 and Figure 11As shown, a second linear electric cylinder 25 for driving the plug 24 to slide is installed in the carrier table 21. A slot 232 is provided in the transmission seat 23. The slot 232 is in plug-in and sliding connection with the end of the plug 24. When the second linear electric cylinder 25 is started, the movement of the plug 24 is controlled so that the pressing column 241 abuts against the outer side of the lead screw 13, restricting the relative rotation between the lead screw 13 and the transmission seat 23.

[0083] To facilitate the disassembly and maintenance of the plug 24, as Figure 12 shown, a polygonal connection seat 251 is fixedly installed on the movable end of the second linear electric cylinder 25. The polygonal connection seat 251 is in plug-in connection with the plug 24 and the position is locked by fasteners; by removing the fasteners, the plug 24 can be quickly removed from the polygonal connection seat 251 to facilitate the disassembly and maintenance of the plug 24.

[0084] Combining the above-mentioned multiple embodiments and implementing the continuous operations of multiple links in sequence, including the automatic positioning of the corn seeds 1 at the center of the diameter-determined accommodating tile 26, the automatic feeding of the seed coating material, the formation of a circular seed coating layer on the outer side of the corn seeds 1 by the seed coating material, and the automatic pouring and discharging of the corn seeds 1 that have completed coating and pelletizing. Each component of the equipment cooperates with each other without interference, and the overall structure is compact and ingenious, with good overall use effects.

[0085] The above description is only for the preferred embodiments of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
