Description

Technical Field

[0001] This invention relates to the field of seedling transplanting machinery, and more particularly to a seedling support and soil covering device capable of correcting the uprightness of seedlings. Background Technology

[0002] Due to their high efficiency and cost-effectiveness, transplanting machinery is becoming increasingly widely used. However, a problem exists during the planting process: it cannot guarantee the uprightness of the seedlings planted in the soil. During planting, the interaction between the soil and the planter causes backflow, resulting in the seedlings not being upright after being planted, or even falling over, seriously affecting their normal growth and even causing the roots to be exposed and the seedlings to die. Therefore, it is necessary to straighten the transplanted seedlings to ensure their uprightness in the soil and increase their survival rate. However, there is currently a lack of convenient and quick methods for straightening seedlings. Summary of the Invention

[0003] The purpose of this invention is to provide a seedling support and soil covering device that can correct the uprightness of potted seedlings, and can automatically straighten the potted seedlings conveniently and quickly.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a seedling support and soil covering device that can correct the uprightness of potted seedlings, including a moving trolley, a seedling support mechanism and two soil covering mechanisms. The seedling support mechanism is connected to the moving trolley through a cylinder, and the two soil covering mechanisms are connected to the seedling support mechanism. The cylinder can drive the seedling support mechanism and the two soil covering mechanisms to move up and down relative to the road surface on which the moving trolley travels.

[0005] The seedling support mechanism includes a fixed plate, the top surface of which is connected to the bottom end of a cylinder. A rotating seat, a first motor, and four slide rails are mounted on the bottom surface of the fixed plate. A driven gear is rotatably mounted on the rotating seat. A driving gear that meshes with the driven gear is mounted on the output end of the first motor. The axis of the driven gear coincides with the center line of the cylinder. The four slide rails are distributed circumferentially around the axis of the driven gear, and the length of the four slide rails is matched to form a cross shape. Each of the four slide rails has a slider. The side of the driven gear away from the fixed plate is connected to the rotating plate. One end of the rotating plate is hinged to one end of each of the four arc-shaped connecting rods, and the other end of each of the four arc-shaped connecting rods is hinged to one of the four sliders, so that the rotation of the rotating plate can drive the four sliders to move away from or towards the rotating seat synchronously along the four slide rails.

[0006] The bottom sides of the four sliders are connected to the tops of the four transition plates respectively. Air blowing plates are installed in the middle of the four transition plates respectively. When the four sliders move away from the rotating seat at the same time, a gap can be formed between the adjacent air blowing plates for the seedlings to pass through. When the four sliders move closer to the rotating seat at the same time, the four air blowing plates can cooperate to surround the seedlings located below the rotating plate. Multiple air outlets are opened on the inner surface of the air blowing plates. Interconnected airflow passages are opened inside the transition plates and air blowing plates. An air pump is also installed on the fixed plate. The air pump is connected to the airflow passages of the four transition plates through four air pipes respectively. An angle sensor and a controller are installed on the bottom side of the rotating plate. The angle sensor can detect the angle of the seedlings below. The controller can send air to one or more air pipes according to the angle of the seedlings so that air can be blown towards the seedlings through the air outlets of the corresponding air blowing plates and the angle of the seedlings can be adjusted.

[0007] The soil covering mechanism includes a transition plate and a soil covering plate. The soil covering plate is rotatably connected to the transition plate. A second motor is installed on the transition plate. The second motor can drive the soil covering plate to rotate through a gear set. The transition plates of the two soil covering mechanisms are respectively connected to the bottom ends of two opposite transition rods. The bottom side of the soil covering plate has a soil covering arc surface. When the two soil covering plates rotate downwards on the side away from the transition plate, the soil covering arc surfaces of the two soil covering plates can cooperate to press down the soil on both sides of the seedling.

[0008] Preferably, the fixing plate is a cross-shaped flat plate, and the air pump is installed on the top side of the fixing plate.

[0009] Preferably, each of the four air pipes is equipped with a valve, and the controller can control the opening or closing of each of the four valves.

[0010] According to the above technical solution, the beneficial effects of the present invention are:

[0011] This invention enables a mobile cart to move through the field, reach above the seedlings, detect the angle of the seedlings, straighten them by blowing air, cover the straightened seedlings with soil, and then move to the next seedling. Therefore, this invention can work automatically in the field, accurately and quickly straighten tilted seedlings, and improve the survival rate of seedlings after planting.

[0012] The seedling straightening mechanism of this invention straightens tilted seedlings by air blowing, avoiding contact between the seedling stem and the rigid structure, reducing the clamping damage to the seedling stem. The spacing between adjacent air blowing plates, the height of the air blowing plates relative to the field, and the air pressure can all be adjusted, enabling the straightening and soil covering of seedlings of various sizes and tilt angles, making it highly adaptable.

[0013] The soil covering mechanism of this invention imitates the action of manual soil covering. It uses a soil covering plate with a soil covering surface to compact the soil around the seedling, which can both ensure the uprightness of the seedling and avoid damage to the seedling.

[0021] Referring to the attached diagram, the specific implementation method is as follows:

[0022] like Figure 1 As shown, a seedling support and soil covering device capable of correcting the uprightness of potted seedlings includes a mobile trolley 1, a seedling support mechanism, and two soil covering mechanisms. The seedling support mechanism is connected to the mobile trolley 1 via a cylinder 2, and the two soil covering mechanisms are both connected to the seedling support mechanism. The cylinder 2 can drive the seedling support mechanism and the two soil covering mechanisms to move up and down relative to the road surface on which the mobile trolley 1 travels.

[0023] like Figure 2-5As shown, the seedling support mechanism includes a fixed plate 5, which is a cross-shaped flat plate. The top surface of the fixed plate 5 is connected to the bottom end of the cylinder 2. The bottom surface of the fixed plate 5 is equipped with a rotating seat 11, a first motor 14, and four-segment slide rails 6. A driven gear 12 is rotatably mounted on the rotating seat 11. An active gear 15 that meshes with the driven gear 12 is installed at the output end of the first motor 14. The axis of the driven gear 12 coincides with the center line of the cylinder 2. The four-segment slide rails 6 are distributed circumferentially around the axis of the driven gear 12, and the length direction of the four-segment slide rails 6 is matched to form a cross shape. Each of the four-segment slide rails 6 is provided with a slider 7. The side of the driven gear 12 away from the fixed plate 5 is connected to the rotating plate 16. The rotating plate 16 is hinged to one end of each of the four arc-shaped connecting rods 17, and the other end of each of the four arc-shaped connecting rods 17 is hinged to the four sliders 7, so that the rotation of the rotating plate 16 can drive the four sliders 7 to move away from or towards the rotating seat 11 synchronously along the four-segment slide rails 6.

[0024] like Figure 2-5 As shown, the bottom sides of the four sliders 7 are respectively connected to the top ends of the four transition plates 18. Air blowing plates 9 are installed in the middle of the four transition plates 18. When the four sliders 7 move away from the rotating base 11 simultaneously, a gap is formed between adjacent air blowing plates 9 for the seedlings to pass through. When the four sliders 7 move closer to the rotating base 11 simultaneously, the four air blowing plates 9 can cooperate to surround the seedlings located below the rotating plate 16. Multiple air outlets 10 are provided on the inward-facing surface of the air blowing plates 9. Interconnected airflow passages are provided inside the transition plates 18 and the air blowing plates 9. The fixed plate... An air pump 3 is also installed on the top side of the 5. The air pump 3 is connected to the airflow passage of the four transition plates 18 through four air pipes 4. An angle sensor 13 and a controller are installed on the bottom side of the rotating plate 16. The angle sensor 13 can detect the angle of the seedling below. Valves are installed on the four air pipes 4 respectively. The controller can control the opening or closing of the four valves respectively. The controller can make the air pump 3 send air to one or more air pipes 4 according to the angle of the seedling, so that air can be blown towards the seedling through the air outlet 10 of the corresponding air blowing plate 9 and the angle of the seedling can be adjusted.

[0025] like Figure 6 As shown, the soil covering mechanism includes a transition plate 18 and a soil covering plate 19. The soil covering plate 19 is rotatably connected to the transition plate 18. A second motor 21 is installed on the transition plate 18. The second motor 21 can drive the soil covering plate 19 to rotate through the gear set 20. The transition plates 18 of the two soil covering mechanisms are respectively connected to the bottom ends of two opposite transition rods 8. The bottom side of the soil covering plate 19 has a soil covering arc surface. When the two soil covering plates 19 rotate downward away from the transition plate 18, the soil covering arc surfaces of the two soil covering plates 19 can cooperate to press down the soil on both sides of the seedling.

[0026] The working process of this invention is as follows: the mobile trolley moves in the field, and at this time, a gap is formed between the four air blowing plates in advance for the seedlings to pass through. The soil covering plates of the two soil covering mechanisms are rotated upward so that the air blowing plates and the soil covering plates will not collide with the seedlings. Then the mobile trolley moves to the top of the seedlings, and the tilt sensor collects the seedling size, tilt angle and position information. Then, based on machine vision, the information is processed by the computer and sent to the controller.

[0027] When the seedling is upright, the moving trolley continues to move forward to the next seedling. When the seedling is not upright, the controller controls the cylinder to extend and retract, causing the seedling support mechanism to descend to the sides of the seedling. Then, according to the size of the seedling, the first motor starts and drives the drive gear to rotate. The driven gear drives the arc-shaped connecting rod to rotate, causing the four sliders to move closer synchronously along the four slide rails until the four air blowing plates surround the tilted seedling. Then, the controller controls the air pump to start blowing air and opens the corresponding valves. The airflow is delivered to the corresponding transition plate and air blowing plate through the air pipes. The air is blown towards the seedling through the air outlets distributed on the surface of the air blowing plate to straighten the seedling. During the straightening process, the tilt sensor continuously detects the seedling until the uprightness of the seedling meets the requirements, and then the blowing stops.

[0028] After the seedling is straightened, the controller starts the second motor of the soil covering mechanism. The rotation of the gear set causes the soil covering plate to rotate downwards on the side furthest from the transition plate. This, through the interaction of the two soil covering plates' curved surfaces, presses down the soil on both sides of the seedling. After the operation is complete, the controller resets the cylinder and two motors, allowing the mechanism to move to the next seedling for the next straightening and soil covering process. This invention can automatically work in the field, accurately and quickly straightening tilted seedlings, improving the survival rate after planting, and reducing damage to the seedling stems from clamping or collisions. It can straighten and cover seedlings of various sizes and tilt angles, demonstrating strong adaptability.
