Description

Technical Field

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

[0002] Corn seed coating is a technology widely used in agricultural production. Its main purpose is to increase the germination rate of seeds, promote the growth of seedlings, prevent pests and diseases, and reduce environmental pollution by coating the surface of seeds with a protective film containing micro-fertilizers and plant growth regulators. The existing application number is CN202210545140.1, which is a drum spiral seed pelletizing coating device and its control method. The patent document discloses a method of spraying seed coating powder on the wet seed surface, and ensuring that the seed coating powder can adhere to the seed surface through continuous tumbling treatment. Specifically: the seeds are made to rotate and tumble rapidly in the rotating body through a spiral structure, and the seeds move from one side of the rotating body to the other side 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 sprayed seeds obtain the powder, rolling is used to achieve the adhesion of the powder on the seed surface, thereby achieving seed pelletizing coating, and finally the side wall of the rotating body is heated by a drying device, so that the seeds rounded in the step are dried by heat conduction, and finally the finished pelletized seeds are obtained; However, when using the technical solution in the above-mentioned patent document, in order to ensure that the seed coating agent powder can smoothly adhere to the outer surface of the seed, the outer surface of the seed needs to be fully moistened, which requires that the seeds be fully dried in the subsequent process to prevent the seeds from rotting during storage. However, after the seed coating agent powder forms a thin film layer on the surface of the seed, 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 time required for the drying process. Long-term drying will have an adverse effect on the subsequent germination and growth of the seeds. Therefore, the present application provides a corn seed coating and pelleting equipment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the corn seed coating and pelleting equipment exemplified in the present invention, 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 a seeder is used for sowing operations, the circular seed coating layer makes it easier for corn seeds to roll and discharge during the sowing process, reduces blockage while ensuring single-seed sowing, accurately controls the planting density, avoids seed waste, and has high sowing uniformity, which facilitates subsequent field management, so as to more accurately control the test variables, improve the accuracy and reliability of the test results, and provide more effective data support for the cultivation of excellent corn varieties.

[0017] 2. In the corn seed coating and pelleting equipment exemplified in the present invention, 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, so that the coated and pelletized corn seeds are in the middle position of the circular seed coating layer. The seed coating has good protective performance for the corn seeds, preventing the sowing equipment from causing damage to the corn seeds.

[0018] 3. In the corn seed coating and pelletizing equipment exemplified in the present invention, when the sizing pressing pestle extrude the seed coating material in the sizing containing tile, the seed coating material located at the top edge of the sizing containing tile is first restricted by the inner side surface of the magnetic attraction ring, and because the outer edge of the bottom of the sizing pressing pestle can simultaneously abut against the inner side surface of the magnetic attraction ring and the top inner edge of the magnetic attraction ring to form a tortuous contact surface, in the process of the sizing pressing pestle extruding the coating material multiple times, the tortuous contact surface is used to gradually guide the seed coating material to the inner middle area of ​​the sizing containing tile. As the extrusion operation continues, the seed coating material is effectively sealed between the sizing pressing pestle and the sizing containing tile. In this process, the gap between the magnetic attraction ring and the cover cylinder will not become a channel for the seed coating material to leak, thereby ensuring the stability of the seed coating material during the pelletizing process, ensuring the quality of seed coating and pelletizing, and meeting the requirements for the stability of the coating and pelletizing process during seed processing.

[0019] 4. The corn seed coating and pelletizing equipment exemplified in the present invention utilizes a cover cylinder to shield the seed coating material stored in the sizing container to prevent the seed coating material from splashing around during multiple squeezing of the seed coating material by the sizing pressing pestle, thereby ensuring that the seed coating material is fully filled in each position inside the spherical cavity, thereby constructing a regularly shaped circular seed coating layer on the outside of the corn seed, thereby increasing the effect of the seed coating layer in protecting the corn seeds, improving the seed germination rate, and enhancing the seed stress resistance.

[0020] 5. In the corn seed coating and pelleting equipment of the example of the present invention, the sizing accommodating tile and the T-shaped seat are detachably fixedly mounted on the bearing platform and the synchronous lifting platform respectively, and a plurality of sockets I for the top columns to pass through at the same time are arranged on the bearing platform, and the top edge of the sizing accommodating tile abuts against the lower side of the magnetic attraction ring; sizing accommodating tiles, T-shaped seats and sizing pressing pestles of different sizes are disassembled and replaced, so that the internal size of the spherical cavity can be changed, thereby adapting to the coating and pelleting treatment of different types of plant seeds, and the equipment has a good universal effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0029] Embodiment 1: like Figure 1As shown, the present embodiment provides a corn seed coating and pelleting device, including a carrier platform 21, on which a plurality of sizing accommodating tiles 26 for accommodating corn seeds 1 and seed coating materials are arranged, a synchronous pressing platform 43 is slidably mounted on the upper side of the carrier platform 21, a synchronous lifting platform 31 is slidably mounted on the lower side of the carrier platform 21, and a convex ridge is integrally formed at the end of the synchronous lifting platform 31, which is plugged and slidably connected with a limiting groove 215 at the bottom of the carrier platform 21 to play a role of limiting and guiding; a sizing pressing pestle 44 is detachably fixedly mounted on the synchronous pressing platform 43, and an arc-shaped edge Ⅰ441 and an arc-shaped edge Ⅱ442 are arranged at the bottom of the sizing pressing pestle 44, the arc-shaped edge Ⅰ441 can fit with the upper side surface of the sizing accommodating tile 26, and the arc-shaped edge Ⅱ442 can form a spherical cavity with the inner side surface of the sizing accommodating tile 26.

[0030] The seed coating material used in the present application includes a seed coating agent and a hydrolyzable viscous material; the hydrolyzable viscous material may be natural materials such as pectin, viscose fiber and chitosan, or may be a water-based pressure-sensitive adhesive JS1050-W and a bio-hydrolyzable pressure-sensitive adhesive; under the action of multiple squeezing of the sizing pressing pestle 44, the seed coating material is formed in the spherical cavity between the arc edge II 442 and the inner side of the sizing containing tile 26; The formed seed coating material is round. When a seeder is used for sowing, the round seed coating layer makes it easier for the corn seeds 1 to roll and discharge seeds during the sowing process, thereby reducing blockage while ensuring single-seed sowing, accurately controlling the planting density, avoiding seed waste, and achieving high sowing uniformity, thus facilitating subsequent field management, allowing for more precise control of test variables, improving the accuracy and reliability of test results, and providing more effective data support for the cultivation of excellent corn varieties.

[0031] The outer sides of the sizing receiving tile 26 and the sizing pressing pestle 44 are both provided with Teflon coating to prevent the seed coating material from adhering to the outer surfaces of the sizing receiving tile 26 and the sizing pressing pestle 44 and affecting the seed coating forming of the corn seeds 1.

[0032] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, a T-shaped seat 34 is provided on the synchronous lifting platform 31, and a plurality of top columns 35 capable of penetrating the bottom of the sizing accommodating tile 26 are fixedly installed on the T-shaped seat 34. The top columns 35 are made of rubber material, and the tops of the plurality of top columns 35 can simultaneously fit with the inner side surface of the sizing accommodating tile 26 to prevent the seed coating material from leaking at the bottom position of the sizing accommodating tile 26.

[0033] The specific details of the corn seed coating and pelleting equipment using this application are as follows: 1. Automatically positioning the corn seed 1 at the center of the sizing receiving tile 26; First, manually or using a commercially available picking robot, place the corn seed 1 into the sizing receiving tile 26. Since the sizing receiving tile 26 is provided with a spherical groove, the corn seed 1 automatically slides into the middle side of the bottom of the sizing receiving tile 26. Afterwards, the synchronous lifting platform 31 is controlled to move vertically upward, driving multiple top columns 35 to rise on the middle side of the bottom of the sizing containing tile 26. Since the top columns 35 located at the edge are long and the top columns 35 located in the middle are short, the corn seeds 1 are stably supported by multiple top columns 35, and the corn seeds 1 are automatically positioned at the center of the sizing containing tile 26.

[0034] 2. applying seed coating material to form a circular seed coating layer on the outside of the corn seed 1; First, manually put the seed coating material into the sizing receiving tile 26 and fill it up, apply the seed coating material between the outer side of the corn seed 1 and the plurality of top pillars 35, and use the top pillars 35 and the seed coating material located at the bottom of the corn seed 1 to lift the corn seed 1; Afterwards, the synchronous pressing platform 43 is controlled to move downward, driving the multiple sizing pressing pestles 44 to squeeze the seed coating material in the sizing containing tile 26. Since the seed coating material uses a viscous material inside, the seed coating material is compacted on the outside of the corn seed 1 in the spherical cavity under the action of the sizing pressing pestle 44. In this process, the synchronous lifting platform 31 is slowly controlled to move downward, so that the seed coating material at the bottom of the corn seed 1 is fully in contact with the corn seed 1, avoiding the formation of too deep concave holes on the outer seed coating layer of the corn seed 1 that has been coated and pelletized due to the presence of multiple top pillars 35, and having a good effect in preventing diseases and insect pests. Finally, the corn seeds 1 that have been coated and pelletized are picked up manually or by using a picking robot product available on the market. Since the seed coating layer is round under the action of the spherical cavity, the round seed coating layer can ensure a more uniform distribution of seeds during the sowing process, thereby achieving a balanced sowing density and ensuring the healthy growth of crops throughout the entire growth cycle.

[0035] In the above step one, after the corn seed 1 completes automatic positioning at the center of the sizing receiving tile 26, the corn seed 1 maintains a constant distance from the inner side of the sizing receiving tile 26 and the sizing pressing pestle 44, so that the coated and pelletized corn seed 1 is in the middle position of the circular seed coating layer. The seed coating has good protective performance for the corn seed 1, avoiding damage to the corn seed 1 by the sowing equipment.

[0036] In the above step 2, electric heating components can be built into the support platform 21 and the sizing pressing pestle 44 to heat the thicker seed coating on the outside of the corn seed 1 to improve its molding effect; since the seed coating layer has a certain thickness, and a viscous material is used inside the seed coating material instead of the atomized water used in the prior art, there is no need to dry the moisture between the outer surface of the seed and the seed coating layer for a long time while ensuring the uniform molding of the seed coating layer, thereby avoiding the rotting phenomenon caused by the penetration of moist moisture on the seed surface into the interior of the seed, allowing the seed to germinate and grow smoothly, avoiding adverse effects on the corn seed 1.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, a chimeric arm 22 is fixedly installed on one side of the support platform 21, and the chimeric arm 22 is slidably connected to the transverse axis 12. A transmission seat 23 is fixedly installed on the other side of the support platform 21, and the transmission seat 23 is connected to the screw rod 13 by threaded transmission; the ends of the transverse axis 12 and the screw rod 13 are connected together through the main base 11, and the screw rod 13 is rotatably connected to the main base 11, and a servo motor for driving the screw rod 13 to rotate is installed on the main base 11; the servo motor is started to control the rotation of the screw rod 13, and the threaded transmission connection between the screw rod 13 and the transmission seat 23 is utilized to drive the support platform 21 to move horizontally on the transverse axis 12; by controlling the vibration generated by the horizontal reciprocating movement of the support platform 21, the seed coating material is evenly filled inside the sizing holding tile 26 and between the multiple top columns 35.

[0038] In order to increase the general use of the equipment, such as Figure 5 As shown, the sizing accommodating tile 26 and the T-shaped seat 34 are detachably fixedly mounted on the bearing platform 21 and the synchronous lifting platform 31 respectively. The bearing platform 21 is provided with a plurality of jacks Ⅰ212 for the top column 35 to pass through at the same time. The top edge of the sizing accommodating tile 26 abuts against the lower side of the magnetic ring 27. The sizing accommodating tile 26, the T-shaped seat 34 and the sizing pressing pestle 44 of different sizes are disassembled and replaced, so that the internal size of the spherical cavity can be changed, thereby adapting to the coating and pelleting treatment of different types of plant seeds, and the equipment has a good universal effect.

[0039] The present application provides the following moving method for the synchronous lifting platform 31: Figure 7 , Figure 8 and Fig.11As shown, a driving control arm 32 is fixedly installed on the side of the synchronous lifting platform 31, and the driving control arm 32 is slidably connected with the sliding mouth 214 on the supporting platform 21. A third linear electric cylinder 33 is arranged at the bottom of the supporting platform 21. The movable end of the third linear electric cylinder 33 is inserted into the socket Ⅱ213 at the bottom of the supporting platform 21 and is detachably fixedly connected with the driving control arm 32; multiple third linear electric cylinders 33 are started synchronously to drive multiple driving control arms 32 to slide vertically in the sliding mouth 214, thereby controlling the vertical movement of the synchronous lifting platform 31 relative to the supporting platform 21.

[0040] The present application provides the following moving method for the synchronous pressing platform 43: Figure 1 and Figure 2 As shown, a plurality of fourth linear electric cylinders 42 are installed on the synchronous pressing platform 43, the movable end of the fourth linear electric cylinder 42 is connected to the synchronous pressing platform 43, and the fixed end of the fourth linear electric cylinder 42 is connected to the auxiliary base II 41; the plurality of fourth linear electric cylinders 42 are started synchronously to drive the synchronous pressing platform 43 to move vertically relative to the supporting platform 21.

[0041] Embodiment 2: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 5 and Figure 6 As shown, in this embodiment, a cover tube 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 tube 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 fixedly installed between the sizing pressing pestle 44 and the cover tube 45, and rings are respectively provided at both ends of the tension spring 46. The two rings are respectively detachably fixedly connected to the sizing pressing pestle 44 and the cover tube 45, and a magnetic attraction ring 27 is detachably fixedly installed on the supporting platform 21, and the magnetic attraction ring 27 is connected to the electromagnet II embedded in the bottom of the cover tube 45 through magnetic adsorption coupling.

[0042] Under the action of the tension spring 46, the cover tube 45 extends downward from the outside of the sizing pressing pestle 44. During the downward movement of the synchronous pressing platform 43, the cover tube 45 abuts against the magnetic ring 27 before the sizing pressing pestle 44. Subsequently, the electromagnet II at the bottom of the cover tube 45 is started, so that the electromagnet II and the magnetic ring 27 are pressed tightly against each other. In this state, the cover tube 45 is used to shield the seed coating material stored in the sizing receiving shoe 26 to prevent the seed coating material from splashing around during multiple squeezing of the seed coating material by the sizing pressing pestle 44, thereby ensuring that the seed coating material is fully filled in various positions inside the spherical cavity, thereby constructing a regularly shaped circular seed coating layer on the outside of the corn seed 1, thereby increasing the effect of the seed coating layer on protecting the corn seeds, improving the seed germination rate and enhancing the seed stress resistance.

[0043] like Figure 5As shown, the inner diameter of the magnetic ring 27 is smaller than the inner diameter of the bottom of the cover tube 45, so that when the cover tube 45 is slightly offset relative to the magnetic ring 27 due to uncertainties such as external forces, the cover tube 45 can easily return to its original position by relying on the space around the magnetic ring 27.

[0044] In the process of implementing the above scheme of the present embodiment, when the sizing pressing pestle 44 is controlled to extrude the seed coating material in the sizing containing tile 26, the seed coating material located at the top edge of the sizing containing tile 26 is firstly restricted by the inner side surface of the magnetic attraction ring 27, and because 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 tortuous contact surface is formed; During the process of multiple squeezing of the coating material by the sizing pressing pestle 44, the tortuous contact surface is utilized to gradually guide the seed coating material to the inner middle area of ​​the sizing containing tile 26. As the squeezing operation continues, the seed coating material is effectively sealed between the sizing pressing pestle 44 and the sizing containing tile 26. During this process, the gap between the magnetic ring 27 and the cover tube 45 will not become a channel for leakage of the seed coating material, thereby ensuring the stability of the seed coating material during the pelletizing process, guaranteeing the quality of the seed coating pelletizing, and meeting the requirements for the stability of the coating pelletizing process during the seed processing.

[0045] Embodiment three: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, at least two sub-bases Ⅰ14 are arranged between the two main bases 11, and a feeder 15 is fixedly installed on each sub-base Ⅰ14. A feeding pipe 151 is fixed and connected to the top of the feeder 15, and 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 of the supporting platform 21.

[0046] The inner sides of the bottoms of the feeder 15 , the fixed baffle 16 and the movable baffle 17 form a variable volume discharge channel, and a first linear electric cylinder 19 for driving the movable baffle 17 to move is installed on the inner side of the feeder 15 .

[0047] 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 discharge channel is zero, and the seed coating material enters the feeder 15, the fixed baffle 16 and the movable baffle 17 through the feed pipe 151 for storage.

[0048] When it is necessary to add seed coating material into the sizing receiving tile 26: start the first linear electric cylinder 19, adjust the spacing of the variable volume discharge channel, so that the seed coating material is discharged from the variable volume discharge channel, and at the same time, control the horizontal movement of the supporting platform 21, and the bottom of the fixed baffle 16 and the movable baffle 17 scrape the seed coating material discharged to the supporting platform 21, so that the seed coating material can be evenly filled into multiple sizing receiving tiles 26; compared with the method of manually adding seed coating material in Example 1, the use of the above-mentioned scheme of this embodiment can effectively increase the utilization efficiency of the equipment.

[0049] Embodiment 4: The features common to the third embodiment are not described in detail here. The differences between the third embodiment and the present embodiment are as follows: Figure 1 , Figure 3 and Fig.10 As shown, in this embodiment, a sealing edge 211 is fixedly installed on the top of the supporting platform 21, and the sealing edge 211 is annular and surrounds the top circumference of the supporting platform 21; a sealing strip 18 is fixedly installed on the bottom 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 of the sealing strip 18 abuts against the upper side of the sealing edge 211, so that the seed coating material that slides out between the fixed baffle 16 and the movable baffle 17 is restricted to the area inside the sealing edge 211, so as to avoid the seed coating material scattering everywhere and causing waste.

[0050] Embodiment five: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 , Figure 4 , Figure 7 and Fig. 9 As shown, in this embodiment, an arc groove 221 is provided at the bottom of the engaging arm 22, and the arc groove 221 is slidably connected to the horizontal axis 12. A plug 24 is slidably installed on the supporting platform 21, and a tightening column 241 at the end of the plug 24 can pass through the circular hole 231 on the transmission seat 23 and tighten against the outer side surface of the screw rod 13; the curvature center of the side wall of the arc groove 221 and the rotation center of the screw rod 13 are on the same virtual axis.

[0051] like Figure 4 As shown, a plurality of electromagnets Ⅰ222 are arranged on the lower side of the top of the arc groove 221. The electromagnets Ⅰ222 are coupled to the horizontal axis 12 through magnetic adsorption. When it is necessary to control the horizontal movement of the supporting platform 21, the magnetic adsorption between the electromagnets Ⅰ222 and the horizontal axis 12 is utilized to make the horizontal axis 12 stably embedded in the arc groove 221.

[0052] The plug 24 is controlled to slide on the carrier 21, so that the tightening column 241 at the end of the plug 24 is tightened against the outer side of the screw rod 13; then the servo motor is started to drive the screw rod 13, the carrier 21 and the transmission seat 23 to flip together, so that the arc groove 221 is disengaged from the horizontal axis 12, and the multiple corn seeds 1 that have been coated and pelletized on the carrier 21 are dumped out, reducing the workload of manually picking up the corn seeds 1 that have been coated and pelletized, and improving the automation operation efficiency of the entire equipment in the seed processing link.

[0053] The movement control method of the plug 24 is as follows: Fig. 9 , Fig.10 and Fig.11 As shown, a second linear electric cylinder 25 for driving the plug 24 to slide is installed in the support platform 21, and a slot 232 is provided in the transmission seat 23. The slot 232 is plug-in and slidably connected to the end of the plug 24. The second linear electric cylinder 25 is started to control the movement of the plug 24, so that the tightening column 241 is tightened against the outer side surface of the screw rod 13 to limit the relative rotation between the screw rod 13 and the transmission seat 23.

[0054] In order to facilitate the disassembly and maintenance of the plug 24, Fig.12 As shown, a polygonal connecting seat 251 is fixedly installed on the movable end of the second linear electric cylinder 25, and the polygonal connecting seat 251 is plug-connected to the plug 24 and locked in position by fasteners; by removing the fasteners, the plug 24 can be quickly removed from the polygonal connecting seat 251, so that the plug 24 can be disassembled and maintained.

[0055] By combining the above-mentioned multiple embodiments, the continuous operations of automatically positioning the corn seeds 1 at the center of the sizing holding tile 26, automatically adding the seed coating material, forming a circular seed coating layer on the outside of the corn seeds 1 by the seed coating material, and automatically dumping and discharging the coated and pelletized corn seeds 1 are sequentially implemented. The various components of the equipment work in coordination without interfering with each other, the overall structure is compact and ingenious, and the overall use effect is good.

[0056] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used.
