Description

Technical Field

[0001] This invention relates to the field of tobacco planting technology, specifically to a transplanting device for tobacco planting that can uniformly create planting holes. Background Technology

[0002] Currently, tobacco seedlings are all raised using floating seedling cultivation and transplanted to the field in March or April. Before transplanting, the field needs to be ridged and then the seedlings are transplanted in holes.

[0003] Currently, most tobacco seedling transplanting is still done manually, with automation only achieved in some steps such as digging holes. However, existing tobacco seedling digging and transplanting devices cannot effectively control the spacing between seedlings during digging, affecting the later growth of the seedlings. At the same time, most existing digging equipment digs holes directly on the field ridges, and the depth of the holes cannot be controlled, which affects the planting and growth of tobacco seedlings.

[0004] To address the aforementioned issues, an improved transplanting device for tobacco planting that can uniformly create planting holes has been designed. Summary of the Invention

[0005] The purpose of this invention is to provide a transplanting device for tobacco planting that can uniformly create planting holes, in order to solve the problems mentioned in the background art.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention uses a semi-digging frame that moves upward to pick up tobacco seedlings from a seedling tube, then moves downward to dig holes on the field ridge, and finally opens the semi-digging frame to plant the tobacco seedlings into the holes, thus achieving rapid planting of tobacco seedlings and improving planting efficiency.

[0019] This invention adjusts the position of the color recognition sensor by moving a sliding frame, enabling the color recognition sensor to detect green tobacco seedlings, thereby determining the planting time for the semi-digging frame, ensuring uniform digging and planting of tobacco seedlings, and improving the planting efficiency of tobacco seedlings.

[0020] This invention uses a detection plate to support the upper end of the field ridge, keeping the moving plate away from the limit switch, thereby determining when the semi-digging frame starts digging. Then, the controller controls the downward movement of the second servo electric cylinder, thereby controlling the digging depth of the semi-digging frame and keeping the digging depth consistent, which facilitates the planting of tobacco seedlings.

[0021] This invention uses inclined spray holes on a detection plate to water tobacco seedlings. During watering, the soil around the seedlings is flushed down to the roots, covering the roots and improving the efficiency of planting. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-5In this embodiment of the invention, a tobacco transplanting device capable of uniformly drilling holes includes a base plate 1. Drive wheels 2 are installed at each of the four corners of the base plate 1 to facilitate its movement. A vertical plate 10 is vertically installed on one side of the upper end of the base plate 1. A handle 11 is installed on the upper end of the side wall of the vertical plate 10 away from the center of the base plate 1. An opening 6 is provided on the base plate 1. A holding plate 12 for placing tobacco seedlings is horizontally installed on the upper end of the side wall of the vertical plate 10 away from the handle 11. A generator 13 for providing electricity is installed on the upper end of the base plate 1.

[0030] The opening 6 is provided with a seedling planting mechanism for digging holes and planting seedlings, and the lower end of the base plate 1 is provided with a spacing mechanism for detecting and determining the spacing between tobacco seedlings.

[0031] The seedling planting mechanism includes a second servo electric cylinder 19, which is vertically installed on the upper end of the base plate 1 on the side of the opening 6 away from the upright plate 10. An installation rod 18 is installed at the output end of the second servo electric cylinder 19. Two first servo electric cylinders 17 are installed at the end of the installation rod 18 away from the second servo electric cylinder 19. The two first servo electric cylinders 17 are on the same horizontal plane, and their output ends are arranged opposite each other. A semi-digging frame 7 is vertically installed at the output end of the first servo electric cylinder 17. The two semi-digging frames 7 can be spliced ​​into a digging frame. The two semi-digging frames 7 are vertically arranged at the center of the opening 6. A controller 14 for controlling the first servo electric cylinders 17 and the second servo electric cylinders 19 is installed on the upper end of the base plate 1. A detection component for ensuring that the digging depth is the same is provided on the side wall of the semi-digging frame 7. A seedling feeding component for feeding tobacco seedlings to the semi-digging frame 7 is provided on the upper end of the base plate 1.

[0032] The detection assembly includes two mounting plates 28 corresponding one-to-one with the semi-excavation frame 7. The mounting plates 28 are horizontally mounted on the side wall of the semi-excavation frame 7. A limiting cylinder 29 is vertically mounted on the mounting plate 28. A sliding rod 30 is slidably connected to the inner wall of the limiting cylinder 29. A moving plate 25 is mounted on the upper end of the sliding rod 30 through the limiting cylinder 29. A detection plate 21 is mounted on the lower end of the sliding rod 30. The lower end of the detection plate 21 is on the same horizontal plane as the lower end of the semi-excavation frame 7. A tension spring 27 is provided between the movable plate 25 and the mounting plate 28 to pull the movable plate 25 closer to the mounting plate 28. The tension spring 27 is sleeved on the limiting cylinder 29. The two ends of the tension spring 27 are respectively installed on the movable plate 25 and the mounting plate 28. A limit switch 26 for use with the movable plate 25 is installed on the upper end of the mounting plate 28. The lower end of the movable plate 25 presses on the limit switch 26. A watering component for watering after planting is provided on the detection plate 21.

[0033] The watering assembly includes a collection frame 32 corresponding to the detection plate 21. The detection plate 21 has several water spray holes 31 that are inclined downward inside. The output end of the water spray holes 31 faces the semi-dug frame 7. The collection frame 32 is installed on the upper end of the detection plate 21 and covers the input end of the water spray holes 31. A water pipe 4 is installed on the upper end of the collection frame 32. A water tank 20 is installed on the end of the water pipe 4 away from the collection frame 32. The water tank 20 is installed on the upper end of the base plate 1. A water pump 3 for conveying water to the collection frame 32 is installed on the water pipe 4.

[0034] In use, the semi-digging frame 7 moves downward. When the lower end of the semi-digging frame 7 contacts the upper end of the ridge, the detection plate 21 will also contact the upper end of the ridge. Then the semi-digging frame 7 continues to move downward to dig a hole on the ridge. The detection plate 21 is supported on the upper end of the ridge. The semi-digging frame 7 drives the mounting plate 28 and the limiting cylinder 29 to move downward, stretches the tension spring 27, and causes the moving plate 25 to disengage from the limit switch 26. The limit switch 26 sends a signal to the controller 14. The controller 14 controls the depth of the second servo electric cylinder 19 to move downward, thereby controlling the depth of the hole dug by the semi-digging frame 7.

[0035] After the semi-digging frame 7 has dug the hole, the two first servo electric cylinders 17 are activated to move the two semi-digging frames 7 away from each other, causing the tobacco seedlings inside the semi-digging frame 7 to fall into the newly dug hole. Then, the second servo electric cylinder 19 is activated to move upward. The second servo electric cylinder 19 moves the mounting rod 18, the first servo electric cylinder 17, and the semi-digging frame 7 upward. Under the action of the elastic force, the moving plate 25 approaches the limit switch 26. When the moving plate 25 contacts the limit switch 26, the limit switch 26 sends a signal to the controller 14. The controller 14 controls the water pump 3 to start. The water pump 3 transports the water in the water tank 20 to the inside of the collecting frame 32 through the water pipe 4. The collecting frame 32 transports the water to the inside of the spray hole 31. The spray hole 31 sprays the water obliquely onto the soil around the tobacco seedling, washing the soil onto the tobacco seedling and covering the roots of the tobacco seedling, thus completing the watering work.

[0036] The seedling delivery assembly includes a motor 8, which is mounted on the upper end of the base plate 1 near the side of the opening 6 close to the upright plate 10. A rotating disk 15 is horizontally mounted on the output end of the motor 8. The rotating disk 15 is positioned above the semi-digging frame 7. Several seedling tubes 16, corresponding one-to-one with the semi-digging frames 7, are mounted in a circular array on the rotating disk 15. The seedling tube 16 at the end away from the upright plate 10 is positioned directly above two semi-digging frames 7. The semi-digging frame 7 can fit over the seedling tube 16. The lower ends of the two opposite side walls of the seedling tube 16 are rotatably connected to baffles 23 for sealing the lower end of the seedling tube 16. The center of the baffles 23 is rotatably connected to the lower end of the seedling tube 16. The lower ends of the side walls of the seedling tube 16 are equipped with spring pieces 24 for pushing the baffles 23 to swing horizontally. The end of the spring piece 24 away from the seedling tube 16 is mounted on the baffles 23.

[0037] When in use, the semi-digging frame 7 pushes the baffle 23 to swing, causing the two baffles 23 to open the lower end of the tobacco seed tube 16, so that the tobacco seed inside the tobacco seed tube 16 falls into the semi-digging frame 7.

[0038] Then, the second servo electric cylinder 19 is activated to move downwards. The second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17, and the semi-digging frame 7 to move downwards. The semi-digging frame 7 is disengaged from the tobacco seed tube 16. Under the action of the spring piece 24, the baffle 23 swings back to the horizontal position to seal the lower end of the tobacco seed tube 16. Then, the motor 8 is activated to rotate. The motor 8 drives the rotating disk 15 to rotate. The rotating disk 15 rotates the next tobacco seed tube 16 to be directly above the semi-digging frame 7. At the same time, the staff replenishes tobacco seed tubes 16 with tobacco seedlings.

[0039] The distance-fixing mechanism includes two parallel limiting rails 5, which are installed on both sides of the opening 6. A sliding frame 9 is slidably connected to the limiting rails 5. A color recognition sensor 22 for detecting tobacco seedlings is installed on the lower end of the sliding frame 9 near the upright plate 10. The side wall of the limiting rail 5 is provided with scale lines for determining the distance between the color recognition sensor 22 and the center position of the semi-digging frame 7. A fastening screw for fixing the sliding frame 9 and the limiting rail 5 together is provided on the side of the sliding frame 9 away from the color recognition sensor 22.

[0040] Working principle of tobacco transplanting device that can evenly create planting holes:

[0041] Before use, tobacco seedlings are placed on the top of the holding plate 12. The staff put the tobacco seedlings one by one into the tobacco seedling tube 16. When in use, tobacco seedlings are replenished to the empty tobacco seedling tube 16 in real time.

[0042] At the same time, loosen the fastening screws on the sliding frame 9, and then move the sliding frame 9. The sliding frame 9 drives the color recognition sensor 22 to move. Determine the spacing between the tobacco seedlings according to the scale on the limit track 5. Then tighten the fastening screws to fix the sliding frame 9 and the limit track 5 together. When the color recognition sensor 22 detects green tobacco seedlings, the semi-digging frame 7 can move downward to plant the seedlings.

[0043] In use, the base plate 1 is placed on the ridge, and then the base plate 1 is moved by the drive wheel 2. During the movement of the base plate 1, the second servo electric cylinder 19 is activated to move upward. The second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17 and the semi-digging frame 7 to move upward. The semi-digging frame 7 pushes the baffle 23 to swing, so that the two baffles 23 open the lower end of the tobacco seed tube 16, so that the tobacco seed tube 16 inside the tobacco seed tube 16 falls into the semi-digging frame 7.

[0044] Then, the second servo electric cylinder 19 is activated to move downwards. The second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17, and the semi-digging frame 7 to move downwards. The semi-digging frame 7 is disengaged from the tobacco seed tube 16. Under the action of the spring piece 24, the baffle 23 swings back to the horizontal position to seal the lower end of the tobacco seed tube 16. Then, the motor 8 is activated to rotate. The motor 8 drives the rotating disk 15 to rotate. The rotating disk 15 rotates the next tobacco seed tube 16 to be directly above the semi-digging frame 7. At the same time, the staff replenishes tobacco seed tubes 16 with tobacco seedlings.

[0045] The semi-digging frame 7 continues to move downwards. When the lower end of the semi-digging frame 7 contacts the upper end of the ridge, the detection plate 21 will also contact the upper end of the ridge. Then, the semi-digging frame 7 continues to move downwards to dig a hole on the ridge. The detection plate 21 is supported on the upper end of the ridge. The semi-digging frame 7 drives the mounting plate 28 and the limiting cylinder 29 to move downwards, stretches the tension spring 27, and causes the moving plate 25 to disengage from the limit switch 26. The limit switch 26 sends a signal to the controller 14. The controller 14 controls the depth of the second servo electric cylinder 19 to move downwards, thereby controlling the depth of the hole dug by the semi-digging frame 7.

[0046] After the semi-digging frame 7 has dug the hole, the two first servo electric cylinders 17 are activated to move the two semi-digging frames 7 away from each other, causing the tobacco seedlings inside the semi-digging frame 7 to fall into the newly dug hole. Then, the second servo electric cylinder 19 is activated to move upward. The second servo electric cylinder 19 moves the mounting rod 18, the first servo electric cylinder 17, and the semi-digging frame 7 upward. Under the action of the elastic force, the moving plate 25 approaches the limit switch 26. When the moving plate 25 contacts the limit switch 26, the limit switch 26 sends a signal to the controller 14. The controller 14 controls the water pump 3 to start. The water pump 3 transports the water in the water tank 20 to the inside of the collecting frame 32 through the water pipe 4. The collecting frame 32 transports the water to the inside of the spray hole 31. The spray hole 31 sprays the water obliquely onto the soil around the tobacco seedling, washing the soil onto the tobacco seedling and covering the roots of the tobacco seedling, thus completing the watering work.

[0047] After watering, the two first servo electric cylinders 17 are activated to move the two semi-digging frames 7 closer to each other. The second servo electric cylinder 19 continues to move the semi-digging frames 7 upwards, cooperating with the seedling tube 16 to pick up the seedlings. When the color recognition sensor 22 detects green seedlings, the semi-digging frames 7 can move downwards to plant the seedlings. Repeat the above actions to complete the transplanting of the seedlings.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
