[0019] The application will be described further with reference to the drawings.

[0020] As shown in the drawings Figures 1 to 6 The seedling transplanting machine comprises a vehicle body 1, an inserting mechanism 2 and a posture changing mechanism 3 arranged on the vehicle body 1. The inserting mechanism 2 comprises seedling tongs 4 which can make a downward inserting action after clamping seedlings to transplant the seedlings into the soil. The posture changing mechanism 3 can change the posture of the vehicle body 1 to change the inclination angle of the vehicle body 1, make one end of the vehicle body 1 to make a lifting or sinking action, and the end of the vehicle body 1 which can make the lifting or sinking action is called the lifting and sinking end. The inserting mechanism 2 is installed on the lifting and sinking end of the vehicle body 1. During the running of the seedling transplanting machine, when the seedling tongs 4 clamp the seedlings and make the downward inserting action, the lifting and sinking end of the vehicle body 1 can make the sinking action correspondingly, so as to improve the downward inserting depth of the seedling tongs 4, and correspondingly, the transplanting depth of the seedlings can be improved.

[0021] The lifting and sinking end is the rear end of the vehicle body 1, and correspondingly, the inserting mechanism 2 is installed on the rear end of the vehicle body 1. A pair of front wheels 5 and a pair of rear wheels 6 are installed on the vehicle body 1, and the posture changing mechanism 3 can improve or lower the height of the rear wheels 6 to change the inclination angle of the vehicle body 1, and correspondingly, the rear end of the vehicle body 1 makes the sinking or lifting action. That is to say, when the height of the rear wheels 6 is improved relative to the vehicle body 1, the rear end of the vehicle body 1 sinks, and when the height of the rear wheels 6 is lowered relative to the vehicle body 1, the rear end of the vehicle body 1 lifts. Therefore, when the seedling tongs 4 make the downward inserting action, the height of the rear wheels 6 is improved relative to the vehicle body 1, the rear wheels 6 of the vehicle body 1 sink, and the downward inserting depth of the seedling tongs 4 is improved.

[0022] The posture changing mechanism 3 can drive the front wheels 5 and the rear wheels 6 of the vehicle body 1 to rise and fall together to change the ground clearance of the vehicle body 1. As shown in the drawings Figure 2 When the seedling transplanting machine runs on the hard road surface in the non-planting area, the vehicle body 1 needs to be lifted to increase the ground clearance of the vehicle body 1, so as to avoid the furrow opener 16 and the soil covering wheel 17 on the vehicle body 1 to directly contact the hard road surface and reduce the wear of the furrow opener 16 and the soil covering wheel 17. When the seedling transplanting machine performs the transplanting operation in the planting area, the vehicle body 1 needs to be lowered to reduce the ground clearance of the vehicle body 1, so that the furrow opener 16 and the soil covering wheel 17 contact the soil.

[0023] The lifting and sinking range of the rear wheels 6 of the vehicle body 1 is greater than the lifting and sinking range of the front wheels 5, so that the rear end of the vehicle body 1 can lift or sink. Specifically, as shown in the drawings Figure 3As shown in the drawings, the vehicle body 1 is provided with a front swing arm 7 and a rear swing arm 8, the upper ends of the front swing arm 7 and the rear swing arm 8 are hinged to the vehicle body 1, the lower ends of the front swing arm 7 and the rear swing arm 8 can swing, the front wheel 5 is correspondingly installed at the lower end of the front swing arm 7, and the rear wheel 6 is correspondingly installed at the lower end of the rear swing arm 8. The front swing arm 7 and the rear swing arm 8 are connected through a connecting rod assembly 9, and the connecting rod assembly 9 is connected by a plurality of connecting rods. The posture changing mechanism 3 comprises an extender 10, the extender 10 is installed on the vehicle body 1, the extending end of the extender 10 is connected with the connecting rod assembly 9, so that the extender 10 can pull the connecting rod assembly 9 to displace, and then the connecting rod assembly 9 pulls the front swing arm 7 and the rear swing arm 8 to swing. When the front swing arm 7 swings, the height of the front wheel 5 is correspondingly changed. When the rear swing arm 8 swings, the height of the rear wheel 6 is correspondingly changed.

[0024] In addition, the arm length of the rear swing arm 8 is greater than or equal to the arm length of the front swing arm 7, and when the extender 10 pulls the connecting rod assembly 9 to displace, the swing angle of the rear swing arm 8 is greater than or equal to the swing angle of the front swing arm 7, so that the lifting and lowering amplitude of the rear wheel 6 can be greater than the lifting and lowering amplitude of the front wheel 5. Specifically, referring to the drawings, when the extender 10 extends forward, the front swing arm 7 and the rear swing arm 8 swing downward, and the swing angle of the rear swing arm 8 is greater, so that the lowering amplitude of the rear wheel 6 is greater than that of the front wheel 5, and thus the height of the rear wheel 6 relative to the vehicle body 1 is lowered, and the rear end of the vehicle body 1 performs a lifting action; and when the extender 10 retracts backward, the front swing arm 7 and the rear swing arm 8 swing upward, and the swing angle of the rear swing arm 8 is also greater, so that the lifting amplitude of the rear wheel 6 is greater than that of the front wheel 5, and thus the height of the rear wheel 6 relative to the vehicle body 1 is raised, and the rear end of the vehicle body 1 performs a sinking action.

Figure 5 As shown in the drawings, the transplanting mechanism 2 comprises a transplanting arm 11, and the front end of the transplanting arm 11 is the seedling gripper 4. A rocker 12 and a rotary arm 13 are arranged on the vehicle body 1. One end of the rocker 12 is hinged to the frame of the vehicle body 1, and the other end of the rocker 12 is rotationally connected with the rear end of the transplanting arm 11. One end of the rotary arm 13 is installed on a motor 18, and the other end of the rotary arm 13 is rotationally connected with the middle part of the transplanting arm 11. The motor 18 can drive the rotary arm 13 to rotationally move, the rotary arm 13 drives the transplanting arm 11 to move, and the seedling gripper 4 cyclically performs the actions of downward insertion and upward return. Figure 6 As shown in the drawings, the extender 10 is provided with a motor 14, a transmission mechanism 15, a transmission rod 16 and a transmission lever 17. The transmission rod 16 is connected with the connecting rod assembly 9, and the transmission lever 17 is connected with the transmission rod 16. The motor 14 drives the transmission mechanism 15 to rotate, and the transmission mechanism 15 drives the transmission rod 16 to move forward or backward, and then the transmission lever 17 pulls the connecting rod assembly 9 to displace.

[0026] As shown in the drawings, the extender 10 is provided with a motor 14, a transmission mechanism 15, a transmission rod 16 and a transmission lever 17. The transmission rod 16 is connected with the connecting rod assembly 9, and the transmission lever 17 is connected with the transmission rod 16. The motor 14 drives the transmission mechanism 15 to rotate, and the transmission mechanism 15 drives the transmission rod 16 to move forward or backward, and then the transmission lever 17 pulls the connecting rod assembly 9 to displace. Figure 1 5 ​​As shown in the figure, the seedling tray 14 is arranged on the vehicle body 1, and the seedling tray 14 is arranged in an inclined manner. After the blanket seedlings are placed on the seedling tray 14, the blanket seedlings will move downward along the seedling tray 14. The lower end of the seedling tray 14 is provided with a seedling outlet 15. The seedling tray 14 can reciprocate left and right, so that the seedlings at the bottom end alternately pass through the seedling outlet 15. When the seedling claw 4 performs the downward inserting action, it corresponds to pass through the seedling outlet 15 to clamp the seedlings, and then the seedlings are planted in the soil.

[0027] The vehicle body 1 is also provided with a furrow opener 16 and a soil covering wheel 17. The furrow opener 16, the planting mechanism 2 and the soil covering wheel 17 are sequentially arranged along the direction of travel of the vehicle body 1, that is, the furrow opener 16 is in front of the planting arm 11, and the soil covering wheel 17 is behind the planting arm 11. The furrow opener 16 and the soil covering wheel 17 can be adjusted in height. In addition, the soil covering wheel 17 and the furrow opener 16 are connected to the vehicle body 1 through elastic components, so that the soil covering wheel 17 and the furrow opener 16 have a certain elastic lifting capacity. When the rear end of the vehicle body 1 performs the sinking or lifting action, the furrow opener 16 and the soil covering wheel 17 can maintain contact with the soil.

[0028] The present application also provides a planting operation method of a blanket seedling planting and transplanting machine. The transplanting machine has a low-depth planting operation mode and a high-depth planting operation mode to meet the transplanting depth requirements of different types of seedlings. Generally, the transplanting depth requirement of the seedlings is low, at which time the transplanting machine starts the low-depth planting operation mode. In the low-depth planting operation mode, the transplanting machine is first adjusted to the appropriate height, and then the transplanting machine travels in the planting area. The posture changing mechanism 3 of the transplanting machine is not started during the travel process, and the planting mechanism 2 works alone. When the transplanting depth requirement of the seedlings is high, the transplanting machine starts the high-depth planting operation mode. In the high-depth planting operation mode, the transplanting machine is first adjusted to the appropriate height, and then the transplanting machine travels in the planting area. The posture changing mechanism 3 of the transplanting machine is started during the travel process. When the seedling claw 4 of the planting mechanism 2 performs the downward inserting action, the rear end of the vehicle body 1 correspondingly sinks, and when the seedling claw 4 of the planting mechanism 2 moves upward, the rear end of the vehicle body 1 correspondingly lifts, thereby improving the downward inserting depth of the seedling claw 4 and the transplanting depth of the seedlings.

[0029] Specifically, in the high-depth planting operation mode, when the seedling claw 4 of the planting mechanism 2 is inserted to the lowest point, the rear end of the vehicle body 1 also correspondingly sinks to the lowest point, so that the cooperation effect of the downward inserting action of the seedling claw 4 and the sinking action of the vehicle body 1 is better.

[0030] The above only describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
