[0002] Due to the advantages of high efficiency and cost saving of transplanting machinery, its application is becoming more and more extensive. However, there is a problem that transplanting machinery cannot ensure the uprightness of the seedlings planted in the soil during the planting operation. During the planting operation, the soil will produce a backflow phenomenon due to the interaction with the planter, resulting in the seedlings not being upright after being planted in the soil, and even lodging, which seriously affects the normal growth of the seedlings and even causes the root system of the seedlings to be exposed and die. Therefore, it is necessary to straighten the seedlings after transplanting to ensure the uprightness of the seedlings planted in the soil and increase the survival rate of the seedlings, but there is a lack of a method for straightening the seedlings quickly and conveniently. Summary of the invention

When the four sliding blocks are synchronously away from the rotating seat, gaps for the seedlings to pass through can be formed between the adjacent blowing plates, and when the four sliding blocks are synchronously close to the rotating seat, the four blowing plates can cooperate to surround the seedlings in the pot below the rotating plate. A plurality of air outlet holes are provided on the surface of the blowing plate facing inward, and air flow passages that are interconnected are provided inside the transition plate and the blowing plate.

DETAILED DESCRIPTION

[0012] With reference to the accompanying drawings, the specific implementation is as follows: like Figure 1 As shown, a seedling supporting and soil-covering device capable of correcting the uprightness of seedlings in pots comprises a moving trolley 1, a seedling supporting mechanism and two soil-covering mechanisms. The seedling supporting mechanism is connected to the moving trolley 1 via a cylinder 2, and the two soil-covering mechanisms are both connected to the seedling supporting mechanism.

The top surface of the fixed plate 5 is connected to the bottom end of the cylinder 2, and a rotating seat 11, a first motor 14 and four-section slide rails 6 are installed on the bottom surface of the fixed plate 5. A passive gear 12 is rotatably installed on the rotating seat 11, and an active gear 15 meshing with the passive gear 12 is installed on the output end of the first motor 14. The axis of the passive gear 12 coincides with the center line of the cylinder 2. The four-section slide rails 6 are distributed at intervals along the circumferential direction around the axis of the passive gear 12, and the length direction of the four-section slide rails 6 cooperates to form a cross shape. Slide blocks 7 are respectively provided on the four-section slide rails 6. The side of the passive 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 four arc-shaped connecting rods 17 respectively, and the other ends of the four arc-shaped connecting rods 17 are respectively hinged to four slide blocks 7, so that the four slide blocks 7 are driven by the rotation of the rotating plate 16 to synchronously move away from or approach the rotating seat 11 along the four-section slide rails 6.

[0014] 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, and the middle parts of the four transition plates 18 are respectively installed with air blowing plates 9. When the four sliders 7 are synchronously away from the rotating seat 11, gaps for the seedlings to pass through can be formed between the adjacent air blowing plates 9. When the four sliders 7 are synchronously close to the rotating seat 11, the four air blowing plates 9 can cooperate to surround the seedlings in the pots under the rotating plate 16. The surface of the air blowing plate 9 facing inward is provided with a plurality of air outlet holes 10, and the transition plates 18 and the air blowing plates 9 are provided with air flow passages that are interconnected. The fixed plate An air pump 3 is also installed on the top side of 5, and the air pump 3 is connected to the air flow passages of the four transition plates 18 through four air pipes 4 respectively. An inclination sensor 13 and a controller are installed on the bottom side of the rotating plate 16. The inclination sensor 13 can detect the angle of the pot seedling below. Valves are respectively installed on the four air pipes 4, and the controller can control the opening or closing of the four valves respectively. The controller can make the air pump 3 supply air to one or more air pipes 4 according to the angle of the pot seedling, so as to blow air toward the pot seedling through the air outlet 10 of the corresponding blowing plate 9 and adjust the angle of the pot seedling.

[0015] 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 a gear set 20, the transition plates 18 of the two soil covering mechanisms are respectively connected to the bottom ends of the 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 side of the transition plate 18, the soil on both sides of the seedling pot can be pressed down by the soil covering arc surfaces of the two soil covering plates 19.

[0016] The working process of the present invention is as follows: the mobile cart moves in the field, at which time gaps for the seedlings to pass through are formed in advance between the four blowing plates, and the covering plates of the two covering mechanisms are rotated upward, so that the blowing plates and the covering plates will not collide with the seedlings, and then the mobile cart moves to the top of the seedlings, and the inclination sensor collects the seedling size, inclination angle and position information, and then based on machine vision, the information is transmitted to the controller after computer processing.

[0017] When the uprightness of the seedling pot is good, the mobile trolley continues to move forward to the top of the next seedling pot; when the uprightness of the seedling pot is poor, the controller controls the cylinder to extend and retract, so that the seedling supporting mechanism descends to the four sides of the seedling pot, and then, according to the size of the seedling pot, the first motor is started and drives the active gear to rotate, and the rotation of the arc connecting rod is driven by the passive gear to make the four sliders approach synchronously along the four sections of the slide rails until the four blowing plates surround the inclined seedling pot, and then the controller controls the air pump to start supplying air, and opens the corresponding valves, and transports the airflow to the corresponding transition plate and blowing plate through the air pipe, and blows it toward the seedling pot through the air outlet holes distributed on the surface of the blowing plate, so as to straighten the seedling pot. During the straightening process, the inclination sensor continuously detects the seedling pot until the uprightness of the seedling pot meets the requirements, and then the blowing is stopped.

[0018] After the seedlings are straightened, the controller starts the second motor of the soil covering mechanism, and the side of the soil covering plate away from the transition plate rotates downward through the rotation of the gear set, so that the soil on both sides of the seedlings are pressed down by the soil covering arc surfaces of the two soil covering plates. After the operation is completed, the controller controls the cylinder and the two motors to reset, and continue to move to the top of the next seedling to perform the straightening and soil covering process of the next seedling. The present invention can automatically work in the field, accurately and quickly straighten the tilted seedlings, improve the survival rate of the seedlings after planting, and reduce the clamping or collision damage to the stems of the seedlings, and can perform straightening and soil covering operations on seedlings of various types, sizes, and tilt angles, with strong adaptability.
