A half-hole digging frame 7 is vertically mounted on the output end of the first servo electric cylinder 17. The two half-hole digging frames 7 can be spliced ​​into one hole digging frame. The two half-hole digging frames 7 are vertically arranged at the center of the opening 6. A controller 14 for controlling the first servo electric cylinder 17 and the second servo electric cylinder 19 is mounted on the upper end of the base plate 1. A detection component for making the hole digging depth the same is arranged on the side wall of the half-hole digging frame 7. A seedling delivery component for delivering tobacco seedlings to the half-hole digging frame 7 is arranged on the upper end of the base plate 1.

[0032] The detection assembly includes two mounting plates 28 corresponding to the half-hole-digging frame 7 one by one. The mounting plates 28 are horizontally mounted on the side walls of the half-hole-digging frame 7. A limiting cylinder 29 is vertically mounted on the mounting plates 28. A sliding rod 30 is slidably connected to the inner wall of the limiting cylinder 29. The upper end of the sliding rod 30 passes through the limiting cylinder 29 and is mounted with a moving plate 25. The lower end of the sliding rod 30 is mounted with a detection plate 21. The lower end of the detection plate 21 is on the same horizontal plane as the lower end of the half-hole-digging frame 7. A tension spring 27 is provided between the movable plate 25 and the mounting plate 28 for pulling the movable plate 25 close to the mounting plate 28, the tension spring 27 is sleeved on the limiting cylinder 29, and the two ends of the tension spring 27 are respectively installed on the movable plate 25 and the mounting plate 28, a travel switch 26 used in conjunction with the movable plate 25 is installed on the upper end of the mounting plate 28, the lower end of the movable plate 25 is pressed on the travel switch 26, and a watering component for watering after planting seedlings is provided on the detection plate 21.

The collecting frame 32 is installed on the upper end of the detection plate 21, and the collecting frame 32 is covered on the input end of the water spray hole 31. A water pipe 4 is installed on the upper end of the collecting frame 32, and a water tank 20 is installed on the end of the water pipe 4 away from the collecting frame 32. The water tank 20 is installed on the upper end of the bottom plate 1, and a water pump 3 for transporting water to the collecting frame 32 is installed on the water pipe 4.

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

[0035] After the half-dug hole frame 7 finishes digging the hole, the two first servo electric cylinders 17 are started to drive the two half-dug hole frames 7 away from each other, so that the tobacco seedlings inside the half-dug hole frame 7 fall into the newly dug hole, and then the second servo electric cylinder 19 is started to move upward, and the second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17 and the half-dug hole frame 7 to move upward. Under the action of elastic force, the moving plate 25 approaches the travel switch 26. When the moving plate 25 contacts the travel switch 26, the travel switch 26 sends a signal to the controller 14. The controller 14 controls the water pump 3 to start, and the water pump 3 transports the water inside 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 water spray hole 31. The water spray hole 31 sprays the water obliquely onto the soil around the tobacco seedlings, flushes the soil onto the tobacco seedlings, covers the roots of the tobacco seedlings, and completes the watering work at the same time.

[0036] The seedling delivery assembly includes a motor 8, which is mounted on the upper end of the bottom plate 1 on the side of the opening 6 close to the vertical plate 10. A rotating disk 15 is horizontally mounted on the output end of the motor 8. The rotating disk 15 is arranged above the half-hole-digging frame 7. A plurality of seedling tubes 16 corresponding to the half-hole-digging frames 7 are mounted in a circular array on the rotating disk 15. The seedling tube 16 at one end away from the vertical plate 10 is arranged directly above the two half-hole-digging frames 7. The half-hole-digging frames 7 can be sleeved on the seedling tube 16. The lower ends of the two opposite side walls of the seedling tube 16 are rotatably connected with a baffle 23 for blocking the lower end of the seedling tube 16. The center position of the baffle 23 is rotatably connected to the lower end of the seedling tube 16. The lower end of the side wall of the seedling tube 16 is installed with a spring 24 for pushing the baffle 23 to swing to the horizontal, and the end of the spring 24 away from the seedling tube 16 is installed on the baffle 23.

[0037] When in use, the half-hole frame 7 pushes the baffle 23 to swing, so that the two baffles 23 open the lower end of the smoke seedling tube 16, so that the smoke seedlings inside the smoke seedling tube 16 fall into the half-hole frame 7.

[0038] Then the second servo electric cylinder 19 is started to move downward, and the second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17 and the half-dig hole frame 7 to move downward, and the half-dig hole frame 7 is separated from the smoke seedling tube 16. Under the action of the spring piece 24, the baffle 23 swings back to the horizontal position to block the lower end of the smoke seedling tube 16, and then the motor 8 is started to rotate, and the motor 8 drives the rotating disk 15 to rotate. The rotating disk 15 rotates the next smoke seedling tube 16 to the top of the half-dig hole frame 7, and at the same time, the staff replenishes the empty smoke seedling tube 16 with smoke seedlings.

[0039] The distance-fixing mechanism includes two mutually parallel limiting rails 5, and the two limiting rails 5 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 side of the lower end of the sliding frame 9 close to the vertical plate 10. Scale lines for determining the distance between the color recognition sensor 22 and the center position of the half-dig frame 7 are provided on the side wall of the limiting rail 5. 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 the tobacco planting transplanting device that can evenly punch holes:

[0041] Before use, the tobacco seedlings are placed on the upper end of the containing plate 12 , and the staff puts the tobacco seedlings into the tobacco seedling tube 16 one by one, and replenishes the empty tobacco seedling tube 16 with tobacco seedlings in real time when in use.

[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. The spacing between the tobacco seedlings is determined according to the scale on the limiting track 5, and then the fastening screws are turned to fix the sliding frame 9 and the limiting 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] When in use, the base plate 1 is placed on the ridge of the field, and then the base plate 1 is moved by the driving wheel 2. During the movement of the base plate 1, the second servo electric cylinder 19 is started to move upward. The second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17 and the half-dig hole frame 7 to move upward. The half-dig hole frame 7 pushes the baffle 23 to swing, so that the two baffles 23 open the lower end of the seedling tube 16, thereby allowing the seedlings inside the seedling tube 16 to fall into the half-dig hole frame 7.

[0044] Then the second servo electric cylinder 19 is started to move downward, and the second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17 and the half-dig hole frame 7 to move downward, and the half-dig hole frame 7 is separated from the smoke seedling tube 16. Under the action of the spring piece 24, the baffle 23 swings back to the horizontal position to block the lower end of the smoke seedling tube 16, and then the motor 8 is started to rotate, and the motor 8 drives the rotating disk 15 to rotate. The rotating disk 15 rotates the next smoke seedling tube 16 to the top of the half-dig hole frame 7, and at the same time, the staff replenishes the empty smoke seedling tube 16 with smoke seedlings.

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

[0046] After the half-dug hole frame 7 finishes digging the hole, the two first servo electric cylinders 17 are started to drive the two half-dug hole frames 7 away from each other, so that the tobacco seedlings inside the half-dug hole frame 7 fall into the newly dug hole, and then the second servo electric cylinder 19 is started to move upward, and the second servo electric cylinder 19 drives the mounting rod 18, the first servo electric cylinder 17 and the half-dug hole frame 7 to move upward. Under the action of elastic force, the moving plate 25 approaches the travel switch 26. When the moving plate 25 contacts the travel switch 26, the travel switch 26 sends a signal to the controller 14. The controller 14 controls the water pump 3 to start, and the water pump 3 transports the water inside 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 water spray hole 31. The water spray hole 31 sprays the water obliquely onto the soil around the tobacco seedlings, flushes the soil onto the tobacco seedlings, covers the roots of the tobacco seedlings, and completes the watering work at the same time.

[0047] After watering is completed, the two first servo electric cylinders 17 are started to drive the two half-dug holes frames 7 to move closer to each other, and the second servo electric cylinder 19 continues to drive the half-dug holes frames 7 to move upward, and cooperate with the tobacco seedling tube 16 to take the seedlings. When the color recognition sensor 22 detects green tobacco seedlings, the half-dug holes frames 7 can move downward to plant the seedlings. Repeat the above actions to complete the transplanting of tobacco seedlings.

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