[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] As attached Figures 1 to 6 The blanket seedling transplanter comprises a vehicle body 1, on which a transplanting mechanism 2 and a posture changing mechanism 3 are arranged. The transplanting mechanism 2 comprises a seedling claw 4, which can perform a downward insertion action after clamping the seedlings to plant the seedlings in the soil. The posture changing mechanism 3 can change the posture of the vehicle body 1, change the inclination angle of the vehicle body 1, make one end of the vehicle body 1 tilt up or down, and the end of the vehicle body 1 that can tilt up or down is called the tilting and sinking end. The transplanting mechanism 2 is correspondingly installed on the tilting and sinking end of the vehicle body 1. During the movement of the transplanter vehicle body 1, when the seedling claw 4 clamps the seedlings and performs a downward insertion action, the tilting and sinking end of the vehicle body 1 can cooperate to perform a sinking action, thereby increasing the downward insertion depth of the seedling claw 4, and correspondingly, the planting depth of the seedlings can also be increased.

[0023] The tilting end is the rear end of the vehicle body 1, and accordingly, the planting mechanism 2 is installed at 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 change mechanism 3 can raise or lower the height of the rear wheels 6, so that the tilt angle of the vehicle body 1 changes, and the rear end of the vehicle body 1 sinks or tilts accordingly. In other words, when the height of the rear wheels 6 is raised relative to the vehicle body 1, the rear end of the vehicle body 1 sinks; when the height of the rear wheels 6 is lowered relative to the vehicle body 1, the rear end of the vehicle body 1 tilts. Therefore, when the seedling claw 4 performs the downward insertion action, the height of the rear wheels 6 is raised relative to the vehicle body 1, and the rear wheels 6 of the vehicle body 1 sink, thereby increasing the insertion depth of the seedling claw 4.

[0024] The posture changing mechanism 3 can drive the front wheel 5 and the rear wheel 6 of the vehicle body 1 to rise and fall together, thereby changing the ground clearance of the vehicle body 1. Figure 2 As shown in , when the transplanter is traveling on a hard road in a non-planting area, the vehicle body 1 needs to be raised to increase the ground clearance of the vehicle body 1 to prevent the furrow opener 16 and the covering wheel 17 on the vehicle body 1 from directly contacting the hard road surface and reducing the wear of the furrow opener 16 and the covering wheel 17. When the transplanter is performing planting operations 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 covering wheel 17 can contact the soil.

[0025] On the transplanter body 1, the lifting range of the rear wheel 6 is greater than that of the front wheel 5, so that the rear end of the body 1 can be tilted up or down. Figure 3 As shown in , the vehicle body 1 is provided with a front swing arm 7 and a rear swing arm 8, the upper ends of which are both hinged on the vehicle body 1, so that the lower ends of the front swing arm 7 and the rear swing arm 8 can swing, and 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 by a connecting rod assembly 9, and the connecting rod assembly 9 is formed by connecting a plurality of connecting rods. The posture change mechanism 3 includes a telescopic device 10, which is installed on the vehicle body 1, and the telescopic end of the telescopic device 10 is connected to the connecting rod assembly 9, so that the telescopic device 10 can pull the connecting rod assembly 9 to move, and then pull the front swing arm 7 and the rear swing arm 8 to swing through the connecting rod assembly 9. When the front swing arm 7 swings, the height of the front wheel 5 is changed accordingly. When the rear swing arm 8 swings, the height of the rear wheel 6 is changed accordingly.

[0026] In addition, the length of the rear swing arm 8 is greater than or equal to the length of the front swing arm 7, and when the telescopic device 10 pulls the connecting rod assembly 9 to move, 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 range of the rear wheel 6 can be greater than the lifting range of the front wheel 5. Figure 3 As shown in the figure, when the telescopic device 10 is extended, the front swing arm 7 and the rear swing arm 8 swing downward, and the rear swing arm 8 swings downward at a larger angle, so that the rear wheel 6 is lowered more than the front wheel 5, so the height of the rear wheel 6 relative to the vehicle body 1 is reduced, and the rear end of the vehicle body 1 is tilted; and when the telescopic device 10 is retracted, the front swing arm 7 and the rear swing arm 8 swing upward, and the rear swing arm 8 swings upward at a larger angle, so that the rear wheel 6 is raised more than the front wheel 5, so the height of the rear wheel 6 relative to the vehicle body 1 is increased, and the rear end of the vehicle body 1 is sunk.

[0027] As attached Figure 5 As shown in , the planting mechanism 2 includes a planting arm 11, and the front end of the planting arm 11 is the seedling claw 4. A rocker 12 and a swivel arm 13 are provided on the vehicle body 1. One end of the rocker 12 is hinged on the frame of the vehicle body 1, and the other end of the rocker 12 is rotatably connected to the rear end of the planting arm 11. One end of the swivel arm 13 is mounted on the motor 18, and the other end of the swivel arm 13 is rotatably connected to the middle part of the planting arm 11. The motor 18 can drive the swivel arm 13 to rotate actively, and the swivel arm 13 then drives the planting arm 11 to move, driving the seedling claw 4 to cyclically perform the actions of inserting downward and moving back upward. When the planting arm 11 moves, the movement trajectory of the seedling claw 4 is shown in the attached figure. Figure 6 as shown in .

[0028] As attached Figure 1 and 5As shown in the figure, a seedling loading platform 14 is arranged on the vehicle body 1, and the seedling loading platform 14 is arranged obliquely. After the blanket seedlings are placed on the seedling loading platform 14, they will move down along the seedling loading platform 14. A seedling outlet 15 is arranged at the lower end of the seedling loading platform 14. The seedling loading platform 14 can reciprocate left and right, so that the seedlings at the bottom pass through the seedling outlet 15 alternately, and the seedling claws 4 pass through the seedling outlet 15 when performing the downward insertion action to clamp the seedlings, and then plant the seedlings into the soil.

[0029] The vehicle body 1 is also provided with a furrow opener 16 and a covering wheel 17. The furrow opener 16, the planting mechanism 2 and the covering wheel 17 are arranged in sequence along the traveling direction of the vehicle body 1, that is, the furrow opener 16 is in front of the planting arm 11, and the covering wheel 17 is behind the planting arm 11. The furrow opener 16 and the covering wheel 17 can be raised and lowered to change the height of the furrow opener 16 and the covering wheel 17. In addition, the covering wheel 17 and the furrow opener 16 are connected to the vehicle body 1 through elastic components, so that the covering wheel 17 and the furrow opener 16 have a certain elastic lifting ability, and when the rear end of the vehicle body 1 is sunk or tilted, the furrow opener 16 and the covering wheel 17 can keep in contact with the soil.

[0030] The present invention also provides a planting operation method of a blanket seedling planting transplanter, wherein the transplanter has a low-depth planting operation mode and a high-depth planting operation mode to cope with the transplanting depth requirements of different types of seedlings. Normally, the transplanting depth requirement of the seedlings is low, and at this time the transplanter activates the low-depth planting operation mode. In the low-depth planting operation mode, the transplanter is first adjusted to a suitable height, and then the transplanter moves in the planting area. During the movement, the transplanter does not start the posture change mechanism 3, and the planting mechanism 2 works alone. When the transplanting depth requirement of the seedlings is very high, the transplanter is changed to activate the high-depth planting operation mode. In the high-depth planting operation mode, the transplanter is first adjusted to an appropriate height, and then the transplanter moves in the planting area. During the movement, the transplanter starts the posture change mechanism 3 accordingly. When the seedling claws 4 of the planting mechanism 2 make a downward insertion action, the rear end of the vehicle body 1 sinks accordingly. When the seedling claws 4 of the planting mechanism 2 move back upward, the rear end of the vehicle body 1 rises accordingly, thereby increasing the insertion depth of the seedling claws 4, and then increasing the planting depth of the seedlings.

[0031] Specifically, in the high-depth planting operation mode, when the seedling claws 4 of the planting mechanism 2 are inserted to the lowest point, the rear end of the vehicle body 1 also sinks to the lowest point accordingly, so that the insertion action of the seedling claws 4 and the sinking action of the vehicle body 1 can be better coordinated.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
