DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1: Reference Figure 1-Figure 3 , an intelligent coating device based on corn seed processing, comprising a coating box 6 for processing corn seeds arranged on a supporting frame 2, the coating box 6 is used to quickly coat the corn seeds; A movable bracket 1 is provided at the lower part of the support frame 2, and the overall transport efficiency of the coating device is improved by the movable bracket 1; The coating device also includes: The coating unit is arranged in the coating box 6, and is used to realize the feeding and non-destructive intelligent coating of corn seeds. By adopting a coating method that cooperates pre-coating with rolling coating, the coating effect can be effectively improved, and the corn seeds will not be damaged during coating, and the coating film will not be damaged, so the coating effect is better; The discharging unit is arranged on the coating box 6 and the supporting frame 2, and is used to realize the drying and automatic discharging of the coated corn seeds, consolidate the coating film on the corn seeds, and adopt the hot air drying method to blow dry the coated corn seeds, so that the coating film is quickly dried and solidified, thereby improving the adhesion and consolidation effect of the coating film and improving the adhesion stability of the coating film; A control panel 3 is provided on the support frame 2, and the control panel 3 is used to control the opening and closing and operation status of the coating unit and the discharging unit, so as to realize automatic and intelligent coating of corn seeds.

[0024] Example 2: Reference Figure 3-Figure 11 The technical solution of this embodiment is different from that of the first embodiment in that the coating unit includes a liquid conducting component, a pre-coating component and a swinging component, wherein the liquid conducting component is used to conduct and reflux the coating liquid, the pre-coating component is used to pre-coat the corn seeds, and the swinging component is used to swing the corn seeds after pre-coating to improve the adhesion effect of the coating liquid; The liquid guide assembly includes a storage box 9 fixedly mounted on the coating box 6 for storing the coating liquid, a lifting plate 17 is slidably mounted in the storage box 9, and the coating liquid is located at the lower part of the lifting plate 17, a fixed plate 22 is fixedly mounted in the storage box 9, and an upper liquid pipe 20 for upper liquid is fixedly mounted on the fixed plate 22, and the lifting plate 17 is slidably connected to the upper liquid pipe 20; The lifting plate 17 can move up and down reciprocatingly in the storage box 9 without affecting the upper liquid pipe 20 during the movement, that is, the movement of the lifting plate 17 will not drive the upper liquid pipe 20 to move.

[0025] A reciprocating mechanism is installed in the storage box 9, and the reciprocating mechanism includes a servo motor 5 fixedly installed on the mobile bracket 1, a driving roller 18 is rotatably installed between the driving end of the servo motor 5 and the storage box 9, a reciprocating gear 21 is fixedly installed on the driving roller 18, and a lifting gear rod 19 meshing with the reciprocating gear 21 is fixedly installed on the lifting plate 17; When the servo motor 5 is started, the driving roller 18 on its driving end will be driven to rotate. The rotation of the driving roller 18 will drive the reciprocating gear 21 to rotate. When the reciprocating gear 21 rotates forward, it will drive the lifting gear rod 19 meshing therewith to move upward. When the reciprocating gear 21 rotates reversely, it will drive the lifting gear rod 19 to move downward. By controlling the rotation direction of the driving roller 18 on the driving end of the servo motor 5, the reciprocating lifting and lowering movement of the lifting gear rod 19 can be controlled, thereby driving the lifting plate 17 to make it move back and forth in the storage box 9.

[0026] The upper part of the storage box 9 is fixedly connected with a liquid guide box, and a plurality of liquid spraying pipes 10 are fixedly connected between the liquid guide box and the plurality of coating frames 13. A plurality of liquid return pipes 15 are fixedly connected between the storage box 9 and the coating box 6, and a control valve is arranged on the plurality of liquid return pipes 15 and the upper liquid pipe 20. When the lifting plate 17 moves downward, the coating liquid at the bottom thereof will be squeezed so that it moves upward through the upper liquid pipe 20 (at this time, the upper liquid pipe 20 is in a connected state through the control of the control valve, and the return liquid pipe 15 is closed) and is poured into the upper part of the fixed plate 22, and finally poured into the multiple liquid spray pipes 10 through the liquid guide box. When the lifting plate 17 moves upward, the coating liquid in the coating box 6 will be recovered to the storage box 9 for replenishment through the multiple return liquid pipes 15 (at this time, the return liquid pipe 15 is in a connected state through the control of the control valve, and the upper liquid pipe 20 is closed), thereby completing the recovery of the coating liquid and realizing the recycling of the coating liquid.

[0027] In a further embodiment, the pre-coating assembly includes a pre-coating box 4 fixedly mounted on a coating box 6, and a feed hopper 14 for feeding corn seeds is fixedly connected to the pre-coating box 4, and a plurality of coating frames 13 are fixedly mounted in the pre-coating box 4, and each coating frame 13 is provided with a plurality of spray holes 16 for spraying coating liquid; When coating corn seeds, the corn seeds to be coated are poured into the feed hopper 14. The corn seeds fall into the pre-coating box 4 through the feed hopper 14 under the action of gravity, and finally continue to fall through the pre-coating box 4. When the corn seeds pass through the pre-coating box 4, they will fall through the multiple coating frames 13 in the pre-coating box 4, and the coating liquid in the spray pipe 10 will be poured into the coating frame 13 and sprayed out through the multiple spray holes 16. Since the multiple spray holes 16 are arranged in a surrounding manner, a layer of coating water curtain will be formed in the coating frame 13 when the coating liquid is sprayed out, so that the corn seeds passing through the coating frame 13 will synchronously pass through the coating water curtain, and then a layer of coating film will be attached to the surface of the corn seeds when passing through, thereby realizing the pre-coating of the corn seeds.

[0028] In a further embodiment, the swing assembly includes a swing box 12 fixedly mounted on the driving roller 18, and the swing box 12 is located in the dressing box 6, and a bearing plate 24 is fixedly mounted on the swing box 12; After passing through the pre-coating box 4, the corn seeds will fall into the swing box 12, and at the same time, the coating liquid sprayed out of the coating liquid coating frame 13 will also fall into the swing box 12 synchronously. Since the driving roller 18 reciprocates and the swing box 12 is arranged on the driving roller 18, the swing box 12 will be driven to swing back and forth under the drive of the driving roller 18.

[0029] A screening mesh plate 26 for screening corn seeds is fixedly mounted on the carrier plate 24, a plurality of pouring holes 25 are opened on the side of the swing box 12, and two discharge boxes 23 for discharging corn seeds are arranged on the swing box 12; When the swing box 12 swings back and forth, it drives the multiple corn seeds thereon to swing back and forth, and fully contacts the coating liquid sprinkled on them while swinging back and forth, thereby realizing secondary coating of the corn seeds, further improving the coating effect, and the corn seeds will not collide significantly during the coating process, that is, the corn seeds will not be damaged, and the coating film attached thereto will not fall off; When the corn seeds roll on the carrier plate 24, they will pass through the screening mesh plate 26 on the carrier plate 24. At this time, the smaller volume part of the corn seeds will pass through the screening mesh plate 26 and fall to the bottom of the swing box 12, so that the corn seeds are automatically screened according to the volume, so that the large volume corn seeds remain on the carrier plate 24, and the small volume corn seeds fall to the bottom of the swing box 12; When the swing box 12 swings back and forth, the coating liquid thereon will be poured out through the multiple pouring holes 25 on the side and fall to the bottom of the coating box 6, and finally recovered through the multiple return pipes 15. The pouring holes 25 cooperate to prevent the coating liquid from accumulating in the swing box 12, and prevent the corn seeds from being immersed in the coating liquid for a long time.

[0030] A plurality of swing rollers for assisting the rotation of corn seeds are rotatably mounted on the bottom of the support plate 24 and the swing box 12. The swing rollers assist the rolling of the corn seeds, so that when the swing box 12 swings, the corn seeds can more easily roll left and right in the swing box 12, thereby further improving the coating efficiency.

[0031] Example 3: Reference Figure 1-Figure 3 and 12- Fig.16 The technical solution of this embodiment is different from that of the second embodiment in that the discharging unit includes a carrying component, a drying component and a discharging component, wherein the carrying component is used to collect and temporarily store the coated corn seeds, the drying component is used to dry the corn seeds on the carrying component, and the discharging component is used to automatically discharge the dried corn seeds; The bearing assembly includes a partition plate 11 fixedly installed in the dressing box 6, and two storage boxes 34 are fixedly installed on the partition plate 11, and the two storage boxes 34 are respectively matched with the two discharge boxes 23; Two support frames 35 are fixedly installed in the coating box 6, and two drying plates 32 for carrying corn seeds are rotatably installed between the two support frames 35. After the corn seeds are coated, the two discharge boxes 23 on the swing box 12 can be opened to make the large-volume corn seeds and the small-volume corn seeds fall into the two storage boxes 34 respectively, and finally fall into the two drying plates 32, completing the independent collection and temporary storage of the corn seeds.

[0032] The two drying trays 32 are matched with the two storage boxes 34 respectively. Two electric telescopic rods 33 are fixedly installed on the clothing box 6. The two storage boxes 34 are rotatably installed with linkage rods 36, and the two linkage rods 36 are fixedly installed on the driving ends of the two electric telescopic rods 33 respectively. When the electric telescopic rod 33 is started, the linkage rod 36 on the starting end thereof will be driven to move up and down. When the linkage rod 36 moves up and down, the drying tray 32 will be driven to move up and down. Since the drying tray 32 is rotatably connected to the support frame 35, when one end of the drying tray 32 moves up and down, the drying tray 32 will be tilted and deflected as a whole about the connection point on the support frame 35 as the axis. That is, when the electric telescopic rod 33 is started, the drying tray 32 will be driven to rotate, thereby adjusting the inclination angle of the drying tray 32 to keep it horizontal or tilted downward.

[0033] In a further embodiment, the drying assembly includes a driving motor 27 fixedly mounted on the clothing box 6, and a driving rod 38 is fixedly mounted on the driving end of the driving motor 27, a bellows 8 is fixedly mounted on the clothing box 6, and the driving rod 38 is rotatably connected to the bellows 8, a wind impeller 31 is fixedly mounted on the driving rod 38, and the wind impeller 31 is located in the bellows 8, an air guide box for blowing air is fixedly connected between the bellows 8 and the clothing box 6, and a heating net is arranged in the air guide box, and a plurality of air supply holes for supplying air are opened on the bellows 8; After the corn seeds are loaded and stored, the driving motor 27 can be started to drive the driving rod 38 to rotate. The driving rod 38 rotates, which drives the impeller 31 thereon to rotate. When the impeller 31 rotates, the external air is sucked into the wind box 8 through the air supply hole, and the air is converted into hot air through the heating net and then blown into the coating box 6 through the air guide box. The coating box 6 is provided with exhaust holes, and the hot air blown into the coating box 6 will contact the multiple corn seeds on the two drying plates 32, so that the coating film on the corn seeds can be quickly dried under the blowing and drying effect of the hot air, thereby achieving rapid consolidation of the coating film, so that the coating film can be stably attached to the corn seeds without falling off, thereby completing the coating film attachment process.

[0034] In a further embodiment, the discharging assembly includes a discharging barrel 7 rotatably connected to the coating box 6, and a conveying spiral blade 37 for driving the corn seed discharging is arranged in the discharging barrel 7, a discharging box 30 matched with the discharging barrel 7 is arranged on the supporting frame 2, and an opening and closing door is arranged on the discharging barrel 7, a driving main gear 28 is fixedly installed on the driving rod 38, and a driven gear ring 29 meshing with the driving main gear 28 is fixedly installed on the outside of the discharging barrel 7; After the coating film on the corn seeds is dried, the electric telescopic rod 33 can be started to drive the corresponding drying plate 32 to tilt downward, so that the corn seeds on the drying plate 32 fall into the discharge barrel 7 under the action of gravity; The two electric telescopic rods 33 are independently started, that is, the large-volume corn seeds and the small-volume corn seeds are discharged separately, so as to avoid the corn seeds after screening from being mixed again.

[0035] Starting the drive motor 27 drives the drive rod 38 to rotate, and then drives the main gear 28 to rotate. The rotation of the main gear 28 will drive the driven gear ring 29 meshing with it to rotate, and then drive the discharging barrel 7 to rotate. The rotation of the discharging barrel 7 will drive the conveying spiral blades 37 therein to rotate, thereby realizing automatic spiral conveying and discharging of the corn seeds in the discharging barrel 7, and when the corn seeds are conveyed to the end of the discharging barrel 7, the opening and closing door is opened to allow the corn seeds in the discharging barrel 7 to be discharged through the discharging box 30.

[0036] The number of teeth of the driving main gear 28 is much smaller than the number of teeth of the driven gear ring 29, so that the driving main gear 28 rotates multiple circles before the driven gear ring 29 rotates one circle, thereby realizing the deceleration of the driven gear ring 29, and then without changing the output speed of the driving motor 27 (that is, without affecting the rotation and air discharge of the impeller 31, or the impeller 31 does not drive the discharging barrel 7 to rotate at a high speed when rotating to discharge air), the low-speed rotation and discharging of the discharging barrel 7 can be realized, thereby improving the stability of the corn seed discharging and transportation.

[0037] The specific working principle of this intelligent coating device is: When coating corn seeds, the corn seeds to be coated are poured in through the feed hopper 14. The corn seeds fall into the pre-coating box 4 through the feed hopper 14 under the action of gravity, and then fall into the swing box 12 in the coating box 6 through the multiple coating frames 13 in the pre-coating box 4. When feeding corn seeds, the liquid guide component is started to form a coating water curtain in the coating frame 13 through the cooperation of the liquid guide box and the liquid spray pipe 10, so that the corn seeds passing through the coating frame 13 will synchronously pass through the coating water curtain therein, and then a layer of coating film will be attached to the surface of the corn seeds when passing through, thereby realizing pre-coating of the corn seeds.

[0038] The corn seeds after passing through the pre-coating box 4 will fall into the swing box 12, and the coating liquid sprayed out of the coating liquid coating frame 13 will also fall into the swing box 12 synchronously. Since the driving roller 18 reciprocates and the swing box 12 is arranged on the driving roller 18, the swing box 12 will be driven by the driving roller 18 to swing back and forth. When the swing box 12 swings back and forth, it drives the corn seeds thereon to swing back and forth, and the corn seeds are fully contacted with the coating liquid sprinkled thereon during the swinging, thereby achieving secondary coating of the corn seeds.

[0039] After the corn seeds are coated, the two discharge boxes 23 on the swing box 12 are opened, so that the corn seeds fall into the two storage boxes 34 and finally fall into the two drying trays 32, completing the independent collection and temporary storage of the corn seeds; Start the driving motor 27 to drive the driving rod 38 to rotate. The rotation of the driving rod 38 will drive the impeller 31 thereon to rotate. When the impeller 31 rotates, external air will be sucked into the wind box 8 through the air supply hole, and the air will be converted into hot air after being heated by the heating net and blown into the coating box 6 through the air guide box. The hot air in the coating box 6 will come into contact with the multiple corn seeds on the drying plate 32, and the coating film on the corn seeds can be quickly dried under the blowing and drying action of the hot air, thereby achieving rapid consolidation of the coating film.

[0040] After the coating film on the corn seeds is dried, the electric telescopic rod 33 can be started to drive the corresponding drying plate 32 to tilt downward, so that the corn seeds on the drying plate 32 fall into the discharge barrel 7 under the action of gravity, and the driving motor 27 is started to drive the driving rod 38 to rotate and drive the main gear 28 to rotate. The rotation of the driving main gear 28 will drive the driven gear ring 29 meshing therewith to rotate, and then drive the discharge barrel 7 to rotate. The rotation of the discharge barrel 7 will drive the conveying spiral blade 37 to rotate, thereby realizing the automatic spiral conveying and discharging of the corn seeds in the discharge barrel 7, and when the corn seeds are conveyed to the end of the discharge barrel 7, the opening and closing door is opened, so that the corn seeds in the discharge barrel 7 are discharged through the discharge box 30, and the automatic discharging of the coated corn seeds is completed.

[0041] The embodiment of the present invention further provides an intelligent coating method based on corn seed processing, which is used for the above-mentioned intelligent coating device based on corn seed processing, and comprises the following steps: S1. Pour corn seeds to be coated into the pre-coating component, start the liquid guide component, and pre-coat the corn seeds during the feeding process; S2. Through the cooperation of the swing component and the liquid guide component, the corn seeds are coated again to consolidate the coating effect; S3, collecting the coated corn seeds into a carrying component, and starting a drying component to dry the coating film on the corn seeds to prevent the coating film from falling off; S4, starting the discharging component to realize automatic discharging of the coated corn seeds.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
