When the driving assembly is in operation, the driving assembly can drive the three-section support leg 3 to extend or shorten; the driving assembly includes a connecting spring 126 and an electric screw 127, a connecting spring 126 is connected between the upper part of the movable section 32 of the three-section support leg 3 and the lower part of the swing section 31, an electric screw 127 is vertically installed at the lower part of the movable section 32 of the three-section support leg 3, the electric screw 127 is threadedly connected to the upper part of the support section 33 of the three-section support leg 3, and the electric screw 127 and the angle sensor 125 are electrically connected through the control module.

[0034] First, separate the two arc plates 2, and separate the two arc-shaped inner gear rings 113, and at the same time separate the arc rod Ⅰ12, the arc rod Ⅱ121 and the arc rod Ⅲ122, and then separate the arc rod Ⅰ12 from the telescopic rod 1, then move the two arc plates 2 to both sides of the trunk of the navel orange seedling, and then pull the two arc plates 2 to swing together, connect the two arc plates 2 together with bolts, and put the two arc-shaped inner gear rings 113 together and connect them with bolts, and put the arc rod Ⅰ12, the arc rod Ⅱ121 and the arc rod Ⅲ122 back to their original positions for connection, and then move the entire device so that the three-section support leg 3 is in contact with the ground, and then twist the adjusting screw 7 to rotate forward and backward alternately, and the adjusting screw 7 rotates forward and backward alternately and moves up and down through the internal threaded tube 6, and the adjusting screw 7 is brought The upper arc plate 2 moves up and down, and the upper arc plate 2 moves up and down, and the upper arc plate 2 moves up and down, and drives the upper arc splint 10 to move up and down through the swing frame 8. When the upper arc splint 10 moves up and down to a position suitable for clamping the navel orange seedling, stop twisting the adjusting screw 7, and the upper arc splint 10 stops moving up and down. In this way, the clamping position can be adjusted according to the trunk length of the navel orange seedling, and then the arc-shaped inner gear ring 113 is pulled to rotate forward, and the arc-shaped inner gear ring 113 rotates forward to drive the spur gear 112 to rotate forward, and the spur gear 112 rotates forward to drive the bidirectional screw 111 to rotate forward, and the bidirectional screw 111 rotates forward to drive the upper and lower movable sleeves 11 to move in the direction of approaching each other, and the movable sleeves 11 drive the upper and lower connecting rods 9 to move in the direction of approaching each other, and the connecting rods 9 drive the upper and lower swing frames 8 to approach each other. The arc splint 10 is rotated in the direction of the near side, and the swing frame 8 drives the upper and lower arc splints 10 to swing inwards and contact the navel orange seedlings. The navel orange seedlings make the arc splint 10 swing vertically, and the torsion spring 101 is compressed. When the upper and lower arc splints 10 clamp the navel orange seedlings, the arc inner gear ring 113 stops pulling and rotates forward, and the spur gear 112 stops driving the bidirectional screw 111 to rotate forward, and the arc splint 10 stops swinging inwards. The three-section support leg 3 starts to support and limit the entire device through the connecting rod Ⅰ4 and the connecting rod Ⅱ5, that is, the arc splint 10 supports and limits the growth of the navel orange seedlings to prevent the navel orange seedlings from being blown down in strong winds, and through the action of the arc splint 10, it can adapt to navel orange seedlings of different diameters for clamping and fixing, so that no replacement operation is required. The operation is convenient, thereby improving work efficiency. At the same time, the angle sensor 125 is started to detect the angle change of the arc rod II 121 and the arc rod III 122. If the angle of the arc rod II 121 and the arc rod III 122 changes and is not in the same horizontal plane, the angle sensor 125 controls the corresponding electric screw 127 to start through the control module. The electric screw 127 starts to drive the movable section 32 of the three-section support leg 3 to move up and down. The movable section 32 of the three-section support leg 3 moves up and down and drives the swing section 31 to move up and down through the connecting spring 126. The swing section 31 moves up and down and drives the lower arc plate 2 to swing. The lower arc plate 2 drives the upper arc plate 2 to swing through the telescopic rod 1. The upper and lower arc plates 2 swing through the arc splint 10 to straighten the navel orange seedlings.At the same time, the lower arc plate 2 also drives the arc rod Ⅰ12 to swing through the telescopic rod 1, and the swing of the arc rod Ⅰ12 drives the arc rod Ⅱ121 to swing, and the swing of the arc rod Ⅱ121 drives the arc rod Ⅲ122 to swing. When the navel orange seedling is straightened, the arc rod Ⅰ12, the arc rod Ⅱ121 and the arc rod Ⅲ122 are all in the same horizontal state, and the angle sensor 125 controls the electric screw 127 to be closed through the control module, and the electric screw 127 stops driving the movable section 32 of the three-section support leg 3 to move. Then the device continues to straighten the growth of the navel orange seedling. In this way, whenever the navel orange seedling is crooked, the arc rod Ⅱ121 and the arc rod Ⅲ122 will rotate and are not in the same horizontal state. The angle sensor 125 controls the electric screw 127 through the control module. When the device is started, it swings to straighten the navel orange seedlings. This can be repeated to straighten the navel orange seedlings continuously, so that the operator does not need to check the navel orange seedlings regularly. It is convenient and quick. The counterweight 123 keeps the arc rod III 122 in a stable state. When encountering strong winds, the wind speed sensor 128 detects that the wind speed is too high. The wind speed sensor 128 controls the electromagnet 124 to start through the control module. The electromagnet 124 starts to fix the arc rod II 121 and the arc rod III 122. In this way, it can prevent the strong wind speed from blowing the arc rod II 121 and the arc rod III 122 to swing violently, causing the device to push the navel orange seedlings that have been straightened and cause them to tilt, thereby ensuring the stability of the arc rod II 121 and the arc rod III 122 in strong winds. When the wind speed drops to a stable state, wind speed sensor 128 controls electromagnet 124 through the control module to shut down, arc rod II 121 and arc rod III 122 are no longer fixed, and arc rod II 121 and arc rod III 122 can be used normally. When the navel orange seedlings have grown and no longer need to be straightened, angle sensor 125 is turned off, and arc inner ring gear 113 is pulled to reverse. This reverse rotation of arc inner ring gear 113 drives spur gear 112 to reverse, causing arc clamping plate 10 to swing outward and break contact with the navel orange seedlings. Pulling on arc inner ring gear 113 is stopped, and the two arc inner ring gears 113 and the two arc plates 2 are separated. At the same time, arc rod I 12, arc rod II 121, and arc rod III 122 are separated. The device is then picked up and stored.

[0035] See also Figures 9-11As shown, the seedling straightening device for navel orange planting also includes a fixing assembly installed on the three-section support leg 3, the fixing assembly includes an n-type plate 13, an adjusting screw rod 131, a spiral rod 132, an outer spiral plate 133 and an opening and closing assembly. The support section 33 of the three-section support leg 3 is fixed with the n-type plate 13, the middle of the top of the n-type plate 13 is connected with the adjusting screw rod 131 through a thread, and the lower part of the adjusting screw rod 131 is slidably sleeved with the spiral rod 132 through a spline. When the spiral rod 132 is drilled into the soil, the spiral rod 132 can fix the three-section support leg 3. Four outer spiral plates 133 are evenly spaced and rotatably connected to the spiral rod 132. The outer spiral plates 133 correspond to the spirals of the spiral rod 132. When the outer spiral plate 133 swings outward, the outer spiral plate 133 can provide a stabilizing force for the spiral rod 132. An opening and closing assembly is provided between the outer spiral plate 133 and the adjusting screw rod 131. When the opening and closing assembly is in operation, the opening and closing assembly can drive the outer spiral plate 133 to swing open or close; the opening and closing assembly includes a connecting plate 134 and a buffer spring 135. A buffer spring 135 is connected between the inner lower part of the adjusting screw rod 131 and the inner side of the spiral rod 132. A connecting plate 134 is rotatably connected between the lower part of the outer side surface of the adjusting screw rod 131 and the inner side surfaces of the four outer spiral plates 133. When the connecting plate 134 moves, the connecting plate 134 can drive the outer spiral plate 133 to swing open or close.

[0036] When the three-section support leg 3 is placed on the ground, the adjusting screw rod 131 is twisted to rotate forward, and the adjusting screw rod 131 is reversed to move downward through the thread. The downward movement of the adjusting screw rod 131 drives the screw rod 132 to move downward. At the same time, the reversal of the adjusting screw rod 131 also drives the screw rod 132 to reverse. The screw rod 132 reverses and moves downward at the same time to contact the soil, and the screw rod 132 drills into the soil. When the screw rod 132 drills to the required depth, the twisting of the adjusting screw rod 131 is stopped, and the adjusting screw rod 131 stops driving the screw rod 132 to reverse. When the device supports and limits the navel orange seedlings, the screw rod 132 can make the three-section support leg 3 more stable to support and limit the entire device, making the device more stable to use. When the three-section support leg 3 is affected by strong wind and shakes slightly, the three-section support leg 3 The swing of the supporting leg 3 drives the adjusting screw rod 131 to move upward through the n-type plate 13, and the buffer spring 135 is stretched. The adjusting screw rod 131 moves upward and drives the connecting plate 134 to move upward. The connecting plate 134 moves upward and drives the outer spiral plate 133 to swing outward. The outer spiral plate 133 swings outward into the soil. The outer spiral plate 133 cooperates with the soil to provide a fixing effect on the spiral rod 132, so that the spiral rod 132 is more firmly in the soil, which also has a better fixing effect on the device. When the strong wind weather turns into normal weather, the three-section supporting leg 3 stops being blown. Due to the action of the buffer spring 135, the adjusting screw rod 131 moves downward and drives the three-section supporting leg 3 to move and reset. At the same time, the adjusting screw rod 131 also drives the outer spiral plate 133 to swing inward and reset through the connecting plate 134. When the device is not in use, the adjusting screw 131 is twisted to rotate forward and move upward through the thread. The adjusting screw 131 drives the screw rod 132 to rotate forward and move upward. The screw rod 132 moves upward and breaks contact with the soil. The adjusting screw 131 is stopped, and the screw rod 132 stops fixing the three-section support leg 3. This makes the device more stable and more effective in straightening navel orange seedlings.

[0037] See also Figure 12 As shown, the seedling straightening device for navel orange planting further includes a rubber pad 14. The rubber pad 14 is fixed to the inner side of the arc-shaped clamping plate 10. The rubber pad 14 can increase the friction between the navel orange seedling and the rubber pad 14.

[0038] When the curved clamp 10 swings inward, it drives the rubber pad 14 inward, which then swings inward and contacts the navel orange seedling. The curved clamp 10 clamps the navel orange seedling securely via the rubber pad 14, increasing the friction between the navel orange seedling and the rubber pad 14. When the curved clamp 10 swings outward to reset, it drives the rubber pad 14 outward to reset and disengage the navel orange seedling. This allows the curved clamp 10 to more securely secure the navel orange seedling, thereby improving the clamping effect.
