Description

Technical Field

[0001] The present invention relates to the technical field of seed cultivation, more specifically to rice seed cultivation, and in particular to a rice precision sowing and seedling raising production line. Background Art

[0002] The rice precision sowing and seedling raising production line is the core equipment of modern agricultural mechanized seedling raising. It uses air-suction precision sowing technology to achieve uniform distribution of seeds in the holes of the seedling tray. In the existing technology, the typical whole-tray air-suction rice precision hole seeding production line adopts a modular design such as double-station sowing and robot stacking. It realizes automated operation through processes such as delivering trays, laying bottom soil, pressing holes, sucking seeds, covering soil, and stacking trays. In addition, this type of equipment can also be combined with sensors to control the sowing amount when sowing by air suction to ensure that the error in the number of seeds in each hole meets the standardized seedling raising requirements.

[0003] However, existing production lines lack the ability to perform real-time seed cultivation during the seedling tray injection process. This is particularly true for premature rice seeds, where simultaneous seed soaking or the addition of bioactive substances is required to break seed dormancy, build a stress-resistant microenvironment, and activate seed potential. Traditional equipment only performs sowing, requiring subsequent soaking to be performed independently, resulting in a fragmented process. Some technologies have attempted to implement independent soaking modules or pre-treat seeds before sowing, but these solutions still suffer from low resource utilization and complex process connections.

[0004] To sum up, the core contradiction of the existing sowing production line that is difficult to integrate bioactive substances is that the cultivation during seed sowing needs to be completed in steps, resulting in low efficiency of mixing the reagent with the soil and limited seed soaking effect. As a result, the humic acid component of the bioactive substance is difficult to accurately penetrate the seed surface, and it is impossible to complete the reagent injection and dynamic separation while adsorbing the seeds, resulting in relatively low straw resource utilization efficiency.

The soil mixing module ensures the uniform distribution of phosphate-solubilizing bacteria and Trichoderma in the matrix through the impeller quantitative soil delivery and the spiral mixing design of the stirring frame.

[0019] (3) The adaptation of sowing and process is achieved through a modular linkage mechanism. The seed soaking module adopts a quantitative matching structure of the material dividing notch and the gear block, combined with the scanning and positioning function of the pneumatic seeding head, to ensure that the error of the number of seeds in each hole can be effectively controlled. The linkage frame drives the dual-cavity synchronous operation through a servo motor, so that the delivery sequence of the mixed matrix and the processed seeds is accurately matched. The electric valve control design of the connecting cavity sleeve realizes the integration of the soil base laying and seed implantation processes through alternating opening and closing, avoiding the seed displacement caused by matrix backfilling in traditional equipment, and compressing the soaking, separation and sowing processes to a single station, greatly improving the sowing accuracy.

Furthermore, the accompanying drawings are intended only to more specifically illustrate the embodiments and are not intended to limit the present invention.

[0025] like Figures 1 to 8 As shown, an embodiment of the present invention provides a rice precision sowing and seedling raising production line, comprising a production line support 1, a surface of which is provided with a conveyor belt 2, a multi-axis robotic arm 4 fixedly mounted at the middle position of the side of the production line support 1, an output end of the multi-axis robotic arm 4 is provided with a pill cavity sleeve 9 extending above the conveyor belt 2, and a separating ring sleeve 10 fixedly mounted at the middle end of the outer circumference of the pill cavity sleeve 9; The separating annular sleeve 10 divides the pill cavity sleeve 9 into two groups of symmetrical cavities, one of which is a seed delivery cavity 11 for introducing rice seeds, and the other is a straw processing cavity 12 for introducing straw solid-liquid reagents; Among them, a conveying mechanism 15 for outputting seeds to the outside is also configured at the axial position of the seed conveying chamber 11, and a processing mechanism 16 for separating straw solid-liquid reagents is also configured at the axial position of the straw processing chamber 12. The liquid reagent in the straw solid-liquid reagent is separated by the processing mechanism 16 to soak the rice seeds, and the solid reagent in the straw solid-liquid reagent is separated and mixed into the seedling raising soil, and the seedlings are sown and raised in conjunction with the seedling raising disc on the conveying crawler 2.

[0026] In order to solve the core problem of the conventional rice precision seeding production line in the prior art, the inability to complete the seed biological activity treatment simultaneously during the seeding process during the cultivation stage of rice, resulting in the fragmentation of the process flow, the above technical solution is now adopted to solve the problem. The above technical solution mainly consists of a production line support 1, a conveyor track 2, a multi-axis robotic arm 4, a pill cavity sleeve 9, a separating ring sleeve 10, a seed conveying chamber 11, a straw processing chamber 12, a conveying mechanism 15 and a processing mechanism 16. The production line support 1 serves as the base frame structure of the device, which is used to fix the various components. The configured conveyor track 2 is an automatic conveying structure capable of servo control in the prior art, which is used to cooperate with an external robotic arm and other structures to transport the seedling discs to be processed to different workstations. The configured multi-axis robotic arm 4 is a robotic arm structure capable of multi-directional end movement in the prior art, which is used to control the pill cavity sleeve 9 configured on the output end to move accurately, so as to introduce the seeds and auxiliary reagents stored in the pill cavity sleeve 9 one-to-one into the opening slots of the seedling discs on the conveyor track 2. The configured pill cavity sleeve 9 is similar to the structure of a capsule pill as a whole, with two ends being hemispherical round bottom structures.

[0027] The configured pill cavity sleeve 9 is equally divided by the separating ring sleeve 10, and the interior of the pill cavity sleeve 9 is divided into a seed conveying chamber 11 and a straw processing chamber 12. The outer walls of the seed conveying chamber 11 and the straw processing chamber 12 are both provided with sealing covers for replenishing materials at any time, wherein the straw processing chamber 12 is used to introduce solid and liquid straw raw materials, and the seed conveying chamber 11 is used to introduce rice seed raw materials, wherein the seed conveying chamber 11 is also provided with a conveying mechanism 15 for outputting seeds to the outside at the axial position, and the straw processing chamber 12 is also provided with a processing mechanism 16 for separating straw solid-liquid reagents at the axial position, and the liquid reagent in the straw solid-liquid reagent is separated by the processing mechanism 16 to soak the rice seeds, and the solid reagent in the straw solid-liquid reagent is separated and mixed into the seedling raising soil, and sowing and raising seedlings are carried out in conjunction with the seedling raising disc on the conveying crawler 2.

[0028] Specifically, within the seed delivery chamber 11, the axial delivery mechanism 15 achieves directional transport of rice seeds. Simultaneously, during the seed delivery process, straw fermentation liquid soaking and bioactive material loading are completed simultaneously to achieve synchronous seed cultivation. Specifically, the seeds are immersed in a microenvironment through the straw fermentation liquid circulating in the chamber. The straw fermentation liquid contains small molecular active substances such as fulvic acid and pyroligneous acid. The liquid component penetrates the seed surface through the porous structure, forming a stress-resistant microbial coating. For example, using Bacillus subtilis colonization in the prior art, the activity of seed endosperm enzymes is activated, thereby increasing the germination rate. During the planting process, the seed bioactivity enhancement and stress-resistant microenvironment construction are simultaneously completed, optimizing the cultivation effect before the seeds enter the seedling tray. Within the straw processing chamber 12, through centrifugation and screening effects, the solid and liquid straw raw materials are converted into a dual-channel resource of soaking liquid and matrix raw materials. The liquid component acts on the seeds, and the solid residue is crushed and compounded with soil in proportion to form a lightweight seedling matrix, which can directly replace peat soil to reduce matrix costs. The soil after mixing with solid residues can activate phosphate-solubilizing bacteria and Trichoderma in the solid residues, promote the slow release of nutrients in the seedling stage, and ultimately realize the closed loop of straw resource utilization. The specific working principle is described in the following related structure.

[0029] like Figures 1 to 8 As shown, the side end of the seed delivery chamber 11 is a hemispherical round bottom structure, and a cylindrical sleeve 151 is fixedly installed at the center of the round bottom structure. The delivery mechanism 15 includes a second servo motor 152 fixedly installed on the outside of the cylindrical sleeve 151, and a sleeve cylinder 153 that is movably clamped in the cylindrical sleeve 151 is fixedly installed on the output end of the second servo motor 152. The sleeve cylinder 153 is fixedly installed on the side facing the seed delivery chamber 11 with an extended sleeve 156. The extended sleeve 156 extends into the interior of the seed delivery chamber 11, and a sealing ring that is clamped at the intersection position of the cylindrical sleeve 151 is arranged on the side wall of the extended sleeve 156.

[0030] Among them, the configured sleeve cylinder 153 and the protruding sleeve 156 are an integrated structure, and the whole is movably sleeved on the inside of the cylindrical shell 151 through the corresponding sealing ring. Under the driving action of the output end of the second servo motor 152 on the outside, the sleeve cylinder 153 and the protruding sleeve 156 can be driven around the cylindrical shell 151 to rotate inside the seed conveying chamber 11. On the one hand, it is used to control the first stirring frame 158 on the outside to stir, and on the other hand, it is used to control the first impeller 157 to cooperate with the first stirring frame 158 to rotate seeds outward.

[0031] like Figures 1 to 8As shown, a cavity communicating with the protruding sleeve 156 is provided inside the sleeve 153, and a first impeller 157 is fixedly installed in the cavity. The first impeller 157 extends outward through the protruding sleeve 156, and the protruding end is flush with the separating annular sleeve 10. A first stirring frame 158 is fixedly installed on the outer annular surface of the protruding sleeve 156. An oblique opening 154 is provided on the side wall of the sleeve 153, and the oblique opening 154 is communicated with the cavity inside the sleeve 153. An external hose 155 corresponding to the oblique opening 154 is fixedly installed on the side wall of the cylindrical shell 151.

[0032] like Figures 1 to 8 As shown, the side end of the straw processing chamber 12 is a hemispherical round bottom structure, and a third servo motor 161 is fixedly installed at the center of the round bottom structure. The processing mechanism 16 includes a shaft 162 fixed to the output end of the third servo motor 161, and the shaft 162 is placed as a whole inside the straw processing chamber 12, and a sealing ring that is sealed in the side wall of the straw processing chamber 12 is configured on the side wall of the shaft 162. A scraper 163 attached to the inner wall of the straw processing chamber 12 is fixedly installed on the end of the shaft 162 facing the round bottom structure, and a cleaning brush 164 is fixedly installed on the end of the shaft 162 facing the separating annular sleeve 10. A plurality of cutting frames 165 arranged in a circular pattern are also fixedly installed on the shaft 162 at a position between the scraper 163 and the cleaning brush 164.

[0033] Its Figures 1 to 8 As shown, a side plate 6 is fixedly installed on the output end of the multi-axis robotic arm 4, a first servo motor 7 is fixedly installed on the side end of the side plate 6, a holding frame 8 is fixedly installed on the output end of the first servo motor 7, a pill cavity sleeve 9 is fixedly installed on the outside of the holding frame 8, a sealed pull-out slot 13 is opened on the side of the separating ring sleeve 10, a separating filter plate 14 is inserted into the inner side of the separating ring sleeve 10 through the sealed pull-out slot 13, a seedling tray supply device 3 is fixedly installed on one side end of the production line bracket 1, and a seedling tray pressing device 5 is fixedly installed on the other side end.

[0034] Among them, the configured seedling tray supply device 3 is a seedling tray control device in the prior art, which is used to automatically transport empty seedling trays to the assembly line, supporting horizontal centering positioning and vertical continuous feeding. The configured seedling tray seed pressing device 5 is a seedling tray processing device in the prior art, which is used to gently press the seeds to ensure contact with the soil, improve the seedling emergence rate, cover the seedling tray after sowing, protect the seeds and promote rooting, and use the soil sweeping structure to clean the excess soil at the edge of the seedling tray to ensure the seedling tray is neat, and combine with low-pressure micro-pore spraying to maintain soil moisture. Finally, through an external chain or belt drive, coordinate the synchronous operation of each module, and cooperate with the external mechanical arm to output the finished seedling tray. The surface of the configured partition filter plate 14 is provided with several leaks, the size of which is used to prevent straw solids in the straw processing chamber 12 from entering the seed conveying chamber 11, and at the same time to prevent seeds in the seed conveying chamber 11 from entering the straw processing chamber 12, and the configured sealing pull-out slot 13 is used to provide disassembly requirements for easy replacement. The filter side tubes 166 on both sides are filter tube structures equipped with electric control valves. More specifically, the filter side tube 166 connected to the seed soaking module 17 is a filter head for filtering secondary crushed solids, mainly used for passing liquids, while the filter side tube 166 connected to the soil mixing module 18 is used to discharge all solid materials remaining inside.

[0035] In summary, the specific working states of the configured pill cavity sleeve 9 can be divided into a seed soaking mode and a soil base processing mode; The seed soaking mode is as follows: first, the side plate 6 at the output end is controlled by the multi-axis robotic arm 4 to be in a vertical state of 90 degrees, and then the servo control of the output end of the first servo motor 7 is used to make the holding frame 8 at the output end drive the pill cavity sleeve 9 to be in a vertical state of 90 degrees, and the seed conveying chamber 11 is at the bottom and the straw processing chamber 12 is at the top, that is, the straw processing chamber 12 is at the top of the seed conveying chamber 11. In this state, the straw solid-liquid material stored in the straw processing chamber 12 is separated and filtered by the middle partition filter plate 14, and the internal biomass liquid will flow into the seed conveying chamber 11 to soak the seeds stored in the seed conveying chamber 11.

[0036] The soil base processing mode is as follows: after completing the seed soaking mode, the servo control of the output end of the first servo motor 7 is first used to make the holding frame 8 at the output end drive the pill cavity sleeve 9 to rotate 90 degrees again, so that the seed delivery chamber 11 is located at the top of the straw processing chamber 12. In this state, the liquid originally soaked in the seed delivery chamber 11 will return to the inside of the straw processing chamber 12, so that the seeds stored in the seed delivery chamber 11 are temporarily drained. In order to ensure the stability of the drainage, the servo control of the output end of the first servo motor 7 can be used again when the seed delivery chamber 11 is located at the top of the straw processing chamber 12 to make the top seed delivery chamber 11 rotate back and forth at a small angle to shake out the internal liquid. Then, the second servo motor 152 of the conveying mechanism 15 is turned on, so that the sleeve 153 at the output end of the second servo motor 152 drives the external hose 155 to rotate inside the seed conveying chamber 11. Through the rotating extended sleeve 156, on the one hand, the seeds that are soaked and stuck together in the seed conveying chamber 11 can be stirred by the first stirring frame 158 on the outside. On the other hand, the seeds in the seed conveying chamber 11 can be stirred in the extended sleeve 156 through the continuous rotation of the extended first impeller 157, and with the continuous rotation, they enter the cavity of the sleeve 153. The seeds entering the sleeve 153 are discharged through the oblique through-port 154 on the side, and finally added to the external hose 155 on the outside to complete the processing and conveying of the seeds. At this time, the third servo motor 161 in the processing mechanism 16 is turned on again, and the shaft 162 at the output end of the third servo motor 161 is rotated, and the cutting frame 165 on the shaft 162 is used to crush the straw solids stored in the straw processing chamber 12. As the stirring and crushing is completed, the straw solids are filtered and discharged through the filter side tube 166 on the side of the straw processing chamber 12. In the discharge state, the filter side tube 166 on the side of the seed soaking module 17 is first opened to allow the liquid to enter the interior of the first disc cavity 171 through the filter side tube 166 for secondary soaking, and the remaining solid residue enters the interior of the second disc cavity 181 through the filter side tube 166 for subsequent soil mixing operations.

[0037] like Figures 1 to 8 As shown, the processing mechanism 16 also includes two filtering side tubes 166 fixedly mounted on the hemispherical bottom structure of the straw processing chamber 12, which are 180 degrees apart, and a seed soaking module 17 is arranged at the bottom of one side filtering side tube 166, and a soil mixing module 18 is arranged at the bottom of the other side filtering side tube 166. The seed soaking module 17 includes a first disc cavity 171, and a gear rotating block 172 is movably mounted at the inner center position of the first disc cavity 171. The outer annular edge of the gear rotating block 172 is in contact with the inner wall of the first disc cavity 171, and a plurality of material dividing recesses 173 are arranged in a circular pattern on the outer annular edge of the gear rotating block 172.

[0038] The configured dividing recess 173 can be adjusted according to the reagent seeding situation, and the actual recess size of the dividing recess 173 can be changed according to the number of seeds required to be injected into the opening of the standard seedling tray.

[0039] like Figures 1 to 8 As shown, the interior of the gear block 172 is a cavity structure, and a number of leaks 174 communicating with the internal cavity of the gear block 172 are provided on the arc surface of each material distribution recess 173. An embedded drainage conduit 175 is fixedly installed in the cavity inside the gear block 172. A circular opening for the drainage end of the embedded drainage conduit 175 to extend out is provided at the center position of the first disc cavity 171. The side end of the external hose 155 away from the cylindrical shell 151 is connected to the side of the first disc cavity 171.

[0040] The embedded drainage conduit 175 is a circular conduit structure as a whole, and a plurality of pumping openings are provided on the outer circular surface of the circular conduit, which cooperate with the outer pump to transfer the liquid in the first disc cavity 171.

[0041] like Figures 1 to 8 As shown, the soil mixing module 18 includes a second disc cavity 181, and a concentric soil storage cavity 183 is fixedly installed on the side of the second disc cavity 181. A sealing cover for soil filling is provided on the side wall of the soil storage cavity 183, and a plurality of soil delivery openings are provided on the end surface where the soil storage cavity 183 and the second disc cavity 181 intersect. A second stirring frame 182 is movably installed at the center position of the inner circle of the second disc cavity 181, and a second impeller 184 that is placed as a whole in the soil storage cavity 183 is fixedly installed at the center position of the circle of the second stirring frame 182, and the outer edge surface of the second impeller 184 is attached to the inner wall of the soil storage cavity 183.

[0042] like Figures 1 to 8 As shown, a linkage frame 19 is fixedly installed on the outer surface of the first disc cavity 171 and the second disc cavity 181, and gear sleeves 20 are movably installed at the two side end positions of the linkage frame 19. One side gear sleeve 20 penetrates into the interior of the first disc cavity 171 and is fixedly connected to the center of the gear rotating block 172, and one side gear sleeve 20 penetrates into the interior of the second disc cavity 181 and is fixedly connected to the center of the second stirring frame 182. A fourth servo motor 21 is fixedly installed on the outer side of the linkage frame 19, and the output end of the fourth servo motor 21 is fixedly connected to the center of the gear sleeve 20 on one side, and the outer sides of the gear sleeves 20 on both sides of the linkage frame 19 are engaged through tracks.

[0043] The configured linkage frame 19 engages the gear sleeves 20 on both sides of the interior through the crawler, and driven by the fourth servo motor 21 on the outside, the gear sleeves 20 on both sides can be driven to rotate synchronously.

[0044] like Figures 1 to 8 As shown, the bottom of the first disc cavity 171 and the second disc cavity 181 are fixedly connected with a connecting cavity sleeve 22, and the bottom side walls of the first disc cavity 171 and the second disc cavity 181 are provided with circular openings communicating with the connecting cavity sleeve 22, and electric valves 23 are fixedly installed at the two side ends of the inner cavity of the connecting cavity sleeve 22. The connecting cavity sleeve 22 is a C-shaped circular arc as a whole, and a pneumatic seeding head 24 is fixedly installed at a position in the middle of the connecting cavity sleeve 22, and a seeding gun muzzle 25 is arranged on the output end of the pneumatic seeding head 24.

[0045] The specific working principle of the configured seed soaking module 17 is as follows: First, the soil base processing mode is completed inside the straw processing chamber 12, that is, after the solid straw stored in the straw processing chamber 12 is crushed, the concentration of the liquid stored in the straw processing chamber 12 will be higher, and the activated substance contained will be more stable. After the liquid enters the first disc cavity 171 through the filter side tube 166 on the first disc cavity 171, the meshing gear sleeve 20 is rotated as the output end of the fourth servo motor 21 on the outside of the linkage sleeve 19 is driven, which can make the gear rotating block 172 in the first disc cavity 171 rotate synchronously, so that the liquid passing through the external hose 1 After the initial soaking, the seeds discharged from 55 enter the interior of the first disc cavity 171 and are stuck in the distribution recesses 173 of equal capacity for secondary soaking. After the secondary soaking is completed, the liquid in the entire first disc cavity 171 can be evacuated through the embedded drainage duct 175, and the transferred liquid can be temporarily stored for secondary use of the device. In the evacuated state of the first disc cavity 171, if the gear block 172 is controlled to rotate in this state, the seeds in the distribution recesses 173 can be centrifuged and dried, and injected into the seedling tray in a better state.

[0046] Then, after the straw processing chamber 12 is transferred away, the shaft 162 at the output end is controlled to rotate by the third servo motor 161, and the scraper 163 can be used to introduce the residual material in the straw processing chamber 12 into the interior of the second disc chamber 181 through the filter side tube 166. Then, under the rotation of the second stirring frame 182 inside the second disc chamber 181, the soil inside the second stirring frame 182 can be mixed with the straw material, and as the mixing work continues, the rotating second impeller 184 will continuously inject the soil in the soil storage cavity 183 into the interior of the second disc chamber 181 to complete the subsequent mixing work.

[0047] Then, the seeding gun muzzle 25 is positioned to the opening of each seedling tray in turn through the scanning component of the prior art configured on the pneumatic seeding head 24. During the injection process of each opening, the electric valve 23 on the connecting cavity sleeve 22 near the second disc cavity 181 is first opened, so that the mixed soil in the second disc cavity 181 enters the cavity of the connecting cavity sleeve 22, and is then stably blown into the opening of the seedling tray through the pneumatic seeding head 24. Then, the electric valve 23 on the side of the second disc cavity 181 is closed, and the electric valve 23 on the side of the connecting cavity sleeve 22 near the first disc cavity 171 is opened, so that the seeds in the dividing recess 173 enter the connecting cavity sleeve 22 in a one-to-one order, and are blown into the opening of the seedling tray with the mixed soil through the pneumatic seeding head 24. Each opening of the seedling tray is processed in this way. After the processing is completed, the seedling tray is transported to the seeding tray pressing device 5 by the conveyor belt 2 to complete the final pressing work.

[0048] While the shaft 162 in the straw processing chamber 12 uses the scraper 163 to remove the residual solids, the cleaning brush 164 arranged on the shaft 162 can also simultaneously clean the separation filter plate 14 to ensure the permeability of the leakage opening on the separation filter plate 14.

[0049] The specific production process of the production line provided by the present invention can be summarized as seed soaking, solid-liquid separation, matrix compounding, and finally sowing, forming a full closed-loop utilization of straw resources.
