[0005] Further, the distance adjustment driving parts correspond to the seedling planting arms one by one, so that a plurality of the seedling planting arms can all be driven by the corresponding distance adjustment driving parts to independently displace along the turnover shaft.

[0006] Further, the distance adjustment driving part is a telescopic driving mechanism parallel to the axis of the turnover shaft; the bottom end of the distance adjustment driving part is connected with the turnover shaft through a mounting seat, and the pushing and pulling end of the distance adjustment driving part is connected with the seedling planting arm.

[0007] Further, it comprises a front end connecting piece and a rear end connecting piece; the mounting seat is installed at the bottom end of the distance adjustment driving part through the rear end connecting piece; the telescopic end of the distance adjustment driving part is installed on the seedling planting arm through the front end connecting piece.

[0008] Further, a fastener is radially and movably connected through the turnover shaft, and the mounting seat is installed on the shaft side of the turnover shaft through the fastener.

[0009] Further, the limiting structure is formed by the cooperation of a limiting protrusion on the turnover shaft and a limiting groove on the inner wall of the shaft hole on the seedling planting arm.

[0010] Further, it includes a flipping driving part corresponding to the flipping axis, and the flipping driving part can drive the flipping axis to drive the seedling planting arm thereon to perform a flipping motion.

[0011] Further, it includes side connecting plates installed on both sides of the flipping axis, and the side connecting plates are connected to the locomotive of the agricultural robot.

[0012] Beneficial effects: The present utility model can adjust the spacing between adjacent seedling planting arms on the flipping axis through the spacing adjusting driving part, so as to meet the adjustable requirement of the seedling ridge spacing according to the planting needs.

[0016] The present utility model will be further described below with reference to the drawings.

[0017] As shown in Figure 1 and Figure 2As shown in the figure, a seedling arranging and inserting device for an agricultural robot includes a turning shaft 1, a seedling planting arm 2, and a distance adjustment driving part 3; a plurality of the seedling planting arms 2 are axially arranged in an array on the turning shaft 1, and the seedling planting arm 2 and the turning shaft 1 have a limiting structure 6 in the circumferential direction and are in axial sliding fit. The utility model includes a turning driving part 4 corresponding to the turning shaft 1, and the turning driving part 4 can drive the turning shaft 1 to drive the seedling planting arms 2 thereon to perform a turning motion. It includes side connecting plates 5 installed on both sides of the turning shaft 1, and the side connecting plates 5 are connected to the locomotive of the agricultural robot, so as to install the seedling arranging and inserting device on the locomotive of the agricultural robot. The distance adjustment driving part 3 is relatively fixedly installed on the turning shaft 1 and is connected to the seedling planting arm 2; the distance adjustment driving part 3 can drive the seedling planting arm 2 to axially displace on the turning shaft 1 to adjust the distance between adjacent seedling planting arms 2. The utility model can adjust the distance between adjacent seedling planting arms 2 on the turning shaft 1 through the distance adjustment driving part 3, so as to meet the adjustable requirement of the seedling ridge spacing according to the planting needs. When the seedling bundle is large, the seedling ridge spacing is adjusted to be large, and when the seedling bundle is small, the seedling ridge spacing is adjusted to be small, which greatly improves the adaptability of transplanting planting and improves the convenience and efficiency of agricultural transplanting operations.

[0018] It should be noted that in the present utility model, in order to further improve the adaptability, independent distance adjustment control can be adopted instead of group synchronous distance adjustment control, that is: the distance adjustment driving part 3 corresponds to the seedling planting arm 2 one by one, so that a plurality of the seedling planting arms 2 can all be driven by the corresponding distance adjustment driving part 3 to independently displace along the turning shaft 1.

[0019] More specifically, as Figure 2 and Figure 3 shown, the distance adjustment driving part 3 is a telescopic driving mechanism parallel to the axis of the turning shaft 1; the bottom end of the distance adjustment driving part 3 is connected to the turning shaft 1 through a mounting seat 7, and the pushing and pulling end of the distance adjustment driving part 3 is connected to the seedling planting arm 2. The utility model includes a front end connecting piece 8 and a rear end connecting piece 9; the mounting seat 7 is installed at the bottom end of the distance adjustment driving part 3 through the rear end connecting piece 9; the telescopic end of the distance adjustment driving part 3 is installed on the seedling planting arm 2 through the front end connecting piece 9. A fastener 10 is radially and movably connected through the turning shaft 1, and the mounting seat 7 is installed on the shaft side of the turning shaft 1 through the fastener 10. Among them, the distance adjustment driving part 3 is preferably an electric push rod; both the front end connecting piece 8 and the rear end connecting piece 9 are nuts; the fastener 10 is a bolt, and a groove is opened on the shaft surface of the turning shaft 1 where the bolt is located, and the bottom of the groove is a flat bottom. After the bolt is tightened, its bolt head can be hidden in the groove, so as to avoid hindering the distance adjustment displacement movement of the seedling planting arm 2 on the turning shaft 1.

[0020] As Figure 3As shown in the figure, the limiting structure 6 is formed by the cooperation of the limiting protrusion 61 on the turning shaft 1 and the limiting groove 62 on the inner wall of the shaft hole on the seedling planting arm 2.
