Description

Technical Field

[0001] This invention relates to the field of maize breeding technology, and more specifically to a cultivation device for maize breeding. Background Technology

[0002] Corn breeding generally refers to the sexual reproduction process carried out in agriculture to obtain new varieties or produce seeds. This process mainly adopts soil cultivation, in which corn seeds are sown in the soil in farmland or seedbed. By controlling conditions such as temperature, water, and nutrients, the seeds germinate, grow, tassel, and pollinate, eventually forming mature seeds. After the superior corn seedlings emerge, higher-quality seedlings can be selected and transplanted according to needs to further improve the breeding standards and ensure that the superior varieties have stable genetic traits.

[0003] The current method of maize breeding is fixed soil cultivation. It generally takes 5-10 days for maize to emerge from sowing, depending on soil temperature, humidity and variety characteristics. After emergence, maize enters the seedling growth stage. Environmental factors have a very important impact on the rapid development of roots and leaves. However, the traditional fixed soil cultivation method will cause maize seedlings in the experimental field to be affected by similar environments, making it difficult to control variables. Different environments will also interfere with each other, affecting the transplanting results of seedlings. Therefore, a cultivation device for maize breeding is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that traditional fixed soil cultivation methods cause maize seedlings in experimental fields to be affected by similar environments, making it difficult to control variables and causing interference between different environments, thus affecting the transplanting results of seedlings. This invention provides a cultivation device for maize breeding.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A cultivation device for maize breeding includes a base frame. A horizontally arranged chain conveyor is fixedly installed inside the base frame. A conveyor chain is driven and mounted on the chain conveyor. Multiple evenly distributed traveling frames are fixedly installed on both sides of the conveyor chain. A suspension shaft is fixedly installed at one end of each traveling frame. A first bearing is fixedly sleeved at one end of each suspension shaft. A suspension bracket is fixedly installed on the outer ring of each first bearing. A soil cultivation pot is fixedly installed between two suspension brackets located at the same location. Multiple evenly distributed partitions are fixedly installed inside each soil cultivation pot, and each soil cultivation pot is filled with cultivation soil. An isolation cover is fixedly installed on the top of the base frame. Multiple vertically arranged electric sliding doors are fixedly installed on the top of the isolation cover. The movable ends of the electric sliding doors extend into the interior of the isolation cover. Multiple integrated regulators are provided on the top of the isolation cover, and the multiple integrated regulators and multiple electric sliding doors are arranged alternately. Planting positions and transplanting positions are respectively provided at both ends of the base frame.

[0006] Furthermore, each of the soil cultivation pots is equipped with a disturbance rod inside. Control panels are rotatably mounted at both ends of each soil cultivation pot. The two ends of each disturbance rod pass through multiple partitions and are fixedly connected to two control panels respectively. Multiple control slots are evenly distributed along the axis of the disturbance rod on each control panel. Multiple evenly distributed soil-turning frames are fixedly sleeved on the disturbance rod. These soil-turning frames are staggered with the partitions. Control boxes are fixedly mounted on both sides of each end of the base bracket. Telescopic arms are fixedly mounted inside each control box. The telescopic ends of the telescopic arms face the soil cultivation pot and are fixedly mounted with soil-turning motors. Multiple docking claws adapted to the control slots are fixedly mounted on the output ends of the soil-turning motors. Vision cameras are fixedly mounted on each soil-turning motor. First passage holes corresponding to the positions of the soil-turning motors are opened on both sides of each end of the base bracket.

[0007] Furthermore, a first positioning frame adapted to the soil cultivation pot is fixedly installed at the telescopic end of the telescopic arm.

[0008] Furthermore, a control frame is fixedly installed at the telescopic end of the telescopic arm, and a second positioning frame adapted to the soil cultivation pot is fixedly installed at the top of the control frame. Second passage holes adapted to the second positioning frame are opened on both sides of the bottom support frame, and one end of the second positioning frame extends into the interior of the second passage hole.

[0009] Furthermore, each of the soil-turning frames is fixedly equipped with a soil-shoveling rake, and each of the cultivation soils has cultivation pits corresponding to the positions of the soil-shoveling rakes. Both sides of the top of the hanging frame are fixedly equipped with soil-retaining plates.

[0010] Furthermore, elliptical slides are provided on both sides of the base bracket, and the elliptical slides are adapted to the movement trajectory of the chain plate conveyor. The other end of the suspension shaft extends into the interior of the elliptical slide and is fixedly sleeved with a second bearing.

[0011] Furthermore, multiple mating rubber rollers, evenly distributed along the axis of the suspension shaft, are rotatably mounted on the outer wall of the outer ring of the second bearing.

[0012] Furthermore, each of the suspension brackets has a pull-out base that is slidably mounted on its bottom.

[0013] The beneficial effects of this invention are as follows: 1. This invention uses an integrated regulator to operate the chain conveyor until all the soil-growing pots inside the isolation hood are planted with corn seeds. Each electric sliding door divides the inside of the isolation hood into different areas, which are controlled by each integrated regulator. Different environments are obtained by controlling variables, thereby selecting different corn seedlings according to different growth environments, greatly reducing interference between different environments, shortening the selection time, and improving the selection direction. 2. The cultivation device of the present invention has at least two breeding methods. Another method is to plant in batches according to the seedling raising method at different time periods. Each integrated regulator controls different environments in different isolation areas in the isolation hood. The corn seeds enter each environment in batches, so that the corn seeds obtain the most suitable growth environment at each growth stage. Then, they are transplanted in batches, which greatly reduces the breeding time and improves the seedling survival rate. 3. By setting up a soil turning frame, the soil turning motor drives each soil turning frame to rotate and stir inside the soil cultivation pot through the disturbance rod, so as to automatically turn the soil. The soil turning action on the front and back sides can effectively loosen the soil, avoid soil compaction, and avoid affecting the development of corn seedlings. At the same time, it can make the soil evenly distributed and avoid the change of the center of gravity of the soil cultivation pot from affecting the positioning. 4. By setting up elliptical slides, this invention ensures that during the movement of each soil cultivation pot driven by the chain conveyor, the soil cultivation pot remains in a naturally drooping state under the drive of the first bearing. At the same time, each second bearing is located in the elliptical slide, which guides the movement of the soil cultivation pot, reducing the load on the traveling frame and the conveyor chain. The rubber roller replaces the second bearing in contact with the inner wall of the elliptical slide, which can effectively reduce wear on both. Furthermore, the elastic deformation of the rubber roller itself provides a clearance, making the movement of the soil cultivation pot smoother. Attached Figure Description

Therefore, they should not be construed as limiting the present invention.

[0019] like Figures 1 to 10 As shown, a cultivation device for maize breeding includes a base support 1, such as... Figure 1 , Figure 4 As shown, specifically, a horizontally arranged chain plate type conveyor 2 is fixedly installed inside the base bracket 1. A transmission chain plate 201 is driven and installed on the chain plate type conveyor 2. Multiple evenly distributed traveling frames 3 are fixedly installed on both sides of the transmission chain plate 201. A suspension shaft 4 is fixedly installed at one end of each traveling frame 3. Figure 5 , Figure 8 As shown, a first bearing 5 is fixedly sleeved at one end of each suspension shaft 4, and a suspension bracket 6 is fixedly installed on the outer ring of each first bearing 5. A soil cultivation pot 7 is fixedly installed between two suspension brackets 6 located at the same location. Multiple evenly distributed partitions 8 are fixedly installed inside each soil cultivation pot 7, and each soil cultivation pot 7 is filled with cultivation soil 28. Planting positions 101 and transplanting positions 102 are respectively provided at both ends of the base bracket 1. Figure 7 As shown, each of the suspension brackets 6 has a pull-out base 27 that is slidably installed at its bottom.

[0020] More specifically, in the cultivation device used for corn breeding, two workers stand at the planting position 101 and the transplanting position 102 respectively, and fill the soil pots 7 at both ends with cultivation soil 28. They then separate the pots one by one using partitions 8. Afterwards, the chain plate conveyor 2 drives multiple conveyor chain plates 201 to move intermittently along an elliptical trajectory to change the position of the soil pots 7. The operation is repeated to fill each soil pot 7 with cultivation soil 28. By setting a pull-out bottom plate 27, the workers can use a sampler or soil measuring instrument to test the soil during the soil filling process. They can also pull out the pull-out bottom plate 27 at the bottom of the soil pot 7 to remove the soil that has lost its cultivation function, thus completing the soil renewal and ensuring the quality of breeding.

[0021] like Figure 3 , Figure 9As shown, specifically, a first positioning frame 20 adapted to the soil cultivation pot 7 is fixedly installed at the telescopic end of the telescopic arm 16, a control frame 21 is fixedly installed at the telescopic end of the telescopic arm 16, a second positioning frame 22 adapted to the soil cultivation pot 7 is fixedly installed at the top of the control frame 21, and a second passage hole 104 adapted to the second positioning frame 22 is opened on both sides of the bottom support frame 1, and one end of the second positioning frame 22 extends into the interior of the second passage hole 104.

[0022] More specifically, by setting up the first positioning frame 20 and the second positioning frame 22, when the chain plate conveyor 2 stops, the two sets of telescopic arms 16 located on one side of the planting position 101 and the transplanting position 102 respectively drive each soil turning motor 17 to pass through the first passage hole 103. At the same time, the first positioning frame 20 and the second positioning frame 22 on the telescopic end of the telescopic arm 16 pass through the first passage hole 103 and the second passage hole 104 respectively and are locked on both sides of the soil pot 7 diagonally above and directly above the planting position 101 and the transplanting position 102, positioning a total of four soil pots 7, which facilitates the staff to perform subsequent planting and transplanting operations as well as the automatic soil turning operation of the cultivation soil 28.

[0023] like Figure 1 , Figure 7 , Figure 9 , Figure 10 As shown, specifically, each soil cultivation pot 7 has a disturbance rod 12 inside. Control panels 13 are rotatably mounted at both ends of each soil cultivation pot 7. Multiple partitions 8 pass through both ends of the disturbance rod 12 and are fixedly connected to two control panels 13 respectively. Multiple control slots 1301 are evenly distributed along the axis of the disturbance rod 12 on the control panel 13. Multiple evenly distributed soil turning frames 14 are fixedly sleeved on the disturbance rod 12. The soil turning frames 14 are staggered with the partitions 8. Control boxes 15 are fixedly mounted on both sides of the bottom support 1. Telescopic arms 16 are fixedly mounted inside each control box 15. The telescopic ends of the telescopic arms 16 face the soil cultivation pot 7 and are fixedly mounted with soil turning motors 17. Multiple docking claws 18 that match the control slots 1301 are fixedly mounted on the output ends of the soil turning motors 17. Visual cameras 19 are fixedly mounted on each soil turning motor 17. Figure 3 As shown, the bottom bracket 1 has first passage holes 103 on both sides of both ends, corresponding to the position of the soil turning motor 17.

[0024] In this embodiment, all soil-turning motors 17 are high-load servo motors.

[0025] More specifically, by setting up the soil turning frame 14, during the positioning process of the soil cultivation pot 7, the vision camera 19 will identify the control disks 13 at both ends of the soil cultivation pot 7, drive the soil turning motor 17 to rotate, thereby aligning the docking claw 18 with the control slot 1301 until the docking claw 18 is connected to the control slot 1301. Then, the soil turning motor 17 drives each soil turning frame 14 to rotate and stir inside the soil cultivation pot 7 through the disturbance rod 12, and automatically turn the soil 28. The soil turning action on the front and rear sides can effectively loosen the soil, avoid soil compaction, and avoid affecting the development of corn seedlings. At the same time, it can make the soil evenly distributed and avoid the change of the center of gravity of the soil cultivation pot 7 from affecting the positioning.

[0026] like Figure 7 As shown, specifically, each soil turning frame 14 is fixedly equipped with a soil shovel 25, and each cultivation soil 28 has a cultivation pit 2801 corresponding to the position of the soil shovel 25. Each side of the top of the hanging frame 6 is fixedly equipped with a soil retaining plate 26.

[0027] More specifically, by setting up a soil rake 25, during the soil turning process, the soil rake 25 will individually plow the middle part of the cultivation soil 28 in different isolation areas enclosed by each partition 8, creating cultivation pits 2801 for planting, making it easier for staff to identify the most suitable cultivation pit location, and the soil retaining plates 26 on both sides can intercept soil particles splashed during the soil turning process.

[0028] like Figure 1 , Figure 2 As shown, specifically, an isolation cover 9 is fixedly installed on the top of the base bracket 1, and multiple vertically arranged electric sliding doors 10 are fixedly installed on the top of the isolation cover 9. The movable ends of the electric sliding doors 10 all extend into the interior of the isolation cover 9. Multiple integrated regulators 11 are provided on the top of the isolation cover 9, and the multiple integrated regulators 11 and the multiple electric sliding doors 10 are arranged alternately.

[0029] In this embodiment, the integrated regulator 11 integrates a water supply system, a temperature and humidity regulator, a pH regulator, an atomizer, a natural light simulation lamp, an ultraviolet sterilization regulating lamp, a monitor, and other various regulating and control devices to regulate the environment in real time during the corn breeding and seedling cultivation process.

[0030] More specifically, by setting up an integrated regulator 11, the staff at the planting position 101 plant corn seeds in each cultivation pit 2801. The staff at the transplanting position 102 transplant the seedlings that have been cultivated in the cultivation pit 2801 to the transfer equipment. Then the chain plate conveyor 2 operates again until all the soil pots 7 inside the isolation cover 9 are planted with corn seeds. Each electric sliding door 10 divides the inside of the isolation cover 9 into different areas, which are controlled by each integrated regulator 11 to obtain different environments through the control variable method. This allows for the selection of different corn seedlings according to different growth environments, greatly reducing interference between different environments, shortening the selection time, and improving the selection direction. After cultivation is completed, the electric sliding door 10 resets, and the chain plate conveyor 2 moves intermittently. The staff at the transplanting position 102 transplant different corn seedlings in sequence for further inspection, screening, planting, and selection.

[0031] The cultivation device has at least two breeding methods. One is a preferred embodiment that has been described in detail in this application and will not be repeated here. The other is to plant in batches according to the seedling raising method at different time periods, so that each integrated regulator 11 controls different environments in different isolation areas in the isolation cover 9. The corn seeds enter each environment in batches in sequence, so that the corn seeds obtain the most suitable growth environment at each growth stage. Then, they are transplanted in batches, which greatly reduces the breeding time and improves the seedling survival rate.

[0032] like Figure 4 As shown, specifically, both sides of the base bracket 1 are provided with elliptical slides 105, which are adapted to the movement trajectory of the chain plate conveyor 2. The other end of the suspension shaft 4 extends into the interior of the elliptical slide 105 and is fixedly sleeved with a second bearing 23. Multiple mating rubber rollers 24 are rotatably installed on the outer wall of the outer ring of the second bearing 23, which are evenly distributed along the axis of the suspension shaft 4.

[0033] More specifically, by setting up the elliptical slide 105, during the movement of each soil cultivation pot 7 driven by the chain plate conveyor 2, the soil cultivation pot 7 always maintains a natural downward state under the drive of the first bearing 5. At the same time, each second bearing 23 is located in the elliptical slide 105, which guides the movement of the soil cultivation pot 7, reduces the load on the traveling frame 3 and the transmission chain plate 201. With the rubber roller 24 replacing the second bearing 23 in contact with the inner wall of the elliptical slide 105, the wear of both can be effectively reduced. Furthermore, the elastic deformation of the rubber roller 24 itself provides a fitting gap, making the movement of the soil cultivation pot 7 smoother.

[0034] In summary: Before breeding: When the chain plate conveyor 2 stops, the telescopic arm 16 drives the first positioning frame 20 and the second positioning frame 22 to lock on both sides of the soil pot 7 above the planting position 101 and the transplanting position 102, respectively, positioning a total of four soil pots 7. Two workers stand at the planting position 101 and the transplanting position 102 respectively, and fill the soil pots 7 at both ends with the cultivation soil 28, and use the partition 8 to separate them one by one. Then the chain plate conveyor 2 drives multiple conveyor chain plates 201 to move intermittently along the elliptical trajectory to change the position of the soil pots 7. The operation is repeated to fill each soil pot 7 with cultivation soil 28. The workers can use a sampler or soil measuring instrument to test the soil, and pull out the pull-out base plate 27 at the bottom of the soil pot 7 to discharge the soil in the soil pot 7 that originally lost its cultivation function. Automatic soil turning: During the positioning of the soil cultivation pot 7, the vision camera 19 will identify the control disks 13 at both ends of the soil cultivation pot 7 and drive the soil turning motor 17 to rotate, thereby aligning the docking claw 18 with the control slot 1301 until the docking claw 18 is connected to the control slot 1301. Then, the soil turning motor 17 drives each soil turning frame 14 to rotate and stir inside the soil cultivation pot 7 through the disturbance rod 12, and automatically turns the soil 28. The soil turning action on the front and back sides can effectively loosen the soil and prevent soil compaction. The shovel rake 25 will plow and turn the middle position of the soil 28 in different isolation areas enclosed by each partition 8 separately, and open up the cultivation pit 2801 for planting. During breeding: the staff at planting position 101 plant corn seeds in each cultivation pit 2801, and the staff at transplanting position 102 transplant the seedlings that have been cultivated in the cultivation pit 2801 to the transfer equipment. Then the chain plate conveyor 2 operates again until corn seeds are planted in all the soil pots 7 inside the isolation cover 9. Each electric sliding door 10 divides the inside of the isolation cover 9 into different areas, which are controlled by each integrated regulator 11 to obtain different environments through the control variable method. Thus, different corn seedlings are selected according to different growth environments, greatly reducing the interference between different environments. After breeding: After the breeding is completed, the electric sliding door 10 is reset, and the chain plate conveyor 2 moves intermittently. The staff at the transplanting position 102 transplant different corn seedlings in sequence for further inspection, screening, planting and breeding.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
