This process is repeated until all the seedlings 23 in each row of the seedling tray 22 are transplanted. The spacing between the seedlings 23 in the same row and between adjacent rows of seedlings 23 transplanted into the field is the same.

[0047] As shown in the figure, Figures 1 to 12 The bottom of the seedling shooting cylinder 20 is provided with an acceleration structure 70 for accelerating the shooting of the seedling 23. The seedling 23 along the seedling 23 outlet of the guide area 62 is shot towards the seedling shooting cylinder 20, and the seedling 23 in the seedling shooting cylinder 20 is accelerated to shoot towards the field under the action of the acceleration structure 70, preventing the seedling 23 from floating on the water surface.

[0050] When all the seedlings 23 in the seedling tray 22 are knocked out, the seedling tray 22 falls from the transmission structure 10 into the seedling tray collecting bin 41, and the seedling tray collecting bin 41 plays a collecting role for the seedling tray 22.

[0051] As shown in the accompanying drawings, Figures 1 to 12 As shown, the high-efficiency and orderly seedling 23 transplanting mechanism further comprises a pressing structure 80 pressing the seedling tray 22, the pressing structure 80 comprises a long strip-shaped pressing strip 81 and a plurality of guide strips 82 arranged along the length direction of the pressing strip 81; the pressing strip 81 is fixed to the lower side edge of the guide structure 60, the pressing strip 81 is located directly above the support plate 12 at the front end and has a gap with the support plate 12, and the plurality of guide strips 82 are arranged at the edges of the pressing strip 81 in an alternating manner, and each through hole is located below the adjacent two guide strips 82; during the rotation of the transmission structure 10, the pressing structure 80 presses the seedling tray 22 on the surface of the transmission structure 10, the pushing-out mechanism pushes out the seedling 23 and shoots it into the guide structure 60 along the adjacent guide strips 82.

[0052] As shown in the accompanying drawings, Figures 1 to 12As shown, the transmission structure 10 moves the seedling tray 22 together. When the frontmost row of seedlings 23 in the seedling tray 22 moves directly above the ejection mechanism, the frontmost row of seedlings 22 is pressed between the pressing structure 80 and the transmission structure 10. At this time, the Mth control valve controls the Mth nozzle 31 of several groups of nozzles 31 to eject the seedlings 23 in the seedling tray 22 from the seedling holes 21 at the corresponding positions. The ejected seedlings 23 are shot towards the guide structure 60. The ejection mechanism ejects the first row of seedlings 23 in sequence. When all the seedlings 23 in the frontmost row of the seedling tray 22 have been ejected, the transmission structure 10 moves the seedling tray 22 to one position. At this time, the frontmost row of the seedling tray 22 is disengaged from the transmission structure 10, and the second row of seedlings 22 is pressed between the pressing structure 80 and the transmission structure 10. The ejection mechanism ejects the second row of seedlings in sequence. When all the seedlings 23 in the second row of seedling tray 22 are pushed out, the transmission structure 10 moves the seedling tray 22 one position. At this time, the second row of seedling tray 22 is disengaged from the transmission structure 10, and the third row of seedling tray 22 is pressed between the pressing structure 80 and the transmission structure 10. The pushing mechanism pushes out the third row of seedlings 23 in sequence. When all the seedlings 23 in the third row of seedling tray 22 are pushed out, the transmission structure 10 moves the seedling tray 22 one position.

When all the seedlings 23 in the last row of seedling tray 22 are pushed out, the transmission structure 10 moves the seedling tray 22 one position, at which point the seedling tray 22 is disengaged from the transmission structure 10. After disengaging from the transmission structure 10, the seedling tray 22 falls into the seedling tray collection chamber 41.

[0053] like Figures 1 to 12 As shown, the clamping structure 80 presses against the top of the seedling tray 22 to prevent the seedling tray 22 from detaching from the support plate 12 during the process of expelling the seedlings 23, and also to prevent the seedling tray 22 from detaching from the transmission structure 10. After all the seedlings 23 in the seedling tray 22 have been expelled, the clamping structure 80 releases the seedling tray 22, and the seedling tray 22 detaches from the front end of the transmission structure 10. The next seedling tray 22 moves along the transmission structure 10 to directly above the ejection mechanism 30.

[0054] like Figures 1 to 12 As shown, the guide bar 82 includes a pressing part and an upward-curving part. The pressing part is parallel to the pressing bar 81. The rear end of the upward-curving part is connected to the pressing part, and the front end curves upward.

[0055] like Figures 1 to 12 As shown, when a row of seedlings 23 in the seedling tray 22 moves directly above the pushing mechanism, the row of seedlings in the seedling tray 22 is pressed between the pressing strip 81, the pressing part and the transmission structure 10, and the upturned part is used to separate the multiple seedlings 23.

[0056] like Figures 1 to 12As shown, there is a gap between adjacent support plates 12, and a clamping groove 16 is formed between adjacent support plates 12, which is arranged between the support plates 12. One row of seedling holes 21 in the seedling tray 22 is located in the clamping groove 16, and the other adjacent row of seedling holes 21 is located in the through hole 14 of the support plate 12. The gap between adjacent support plates 12 facilitates the movement of the conveying structure 10.

[0057] As shown in the figure, Figures 1 to 12 As shown, there are eight groups of nozzles 31, each group of nozzles 31 includes ten nozzles 31, and the number of control valves is ten. Eight groups of nozzles 31 have a total of eighty nozzles 31, and each row of seedling holes 21 in the seedling tray 22 has a total of eighty seedling holes 21, and each nozzle 31 corresponds to one seedling hole 21.

[0058] As shown in the figure, Figures 1 to 12 As shown, when a certain row of seedling holes 21 in the seedling tray 22 moves above the pushing mechanism 30, the first control valve controls the first nozzle 31 in each group of nozzles 31 to knock out the seedlings 23 in the corresponding position seedling hole 21, and the knocked out seedlings 23 are shot into the field; then, the second control valve controls the second nozzle 31 in each group of nozzles 31 to knock out the seedlings 23 in the corresponding position seedling hole 21, and the knocked out seedlings 23 are shot into the field; then, the third control valve controls the third nozzle 31 in each group of nozzles 31 to knock out the seedlings 23 in the corresponding position seedling hole 21, and the knocked out seedlings 23 are shot into the field; finally, the eighth control valve controls the eighth nozzle 31 in each group of nozzles 31 to knock out the seedlings 23 in the corresponding position seedling hole 21, and the knocked out seedlings 23 are shot into the field.

[0062] As shown in the figure, Figures 1 to 8As shown, the seedlings 23 pushed out by several nozzles 31 in the same group of nozzles 31 fall into the same seedling shooting cylinder 20. The seedlings 23 pushed out by several nozzles 31 in different groups of nozzles 31 fall into different seedling shooting cylinders 20. Since the spacing between adjacent seedling shooting cylinders 20 is relatively fixed, the distance between the seedlings 23 shot into the field from the seedling shooting cylinders 20 is relatively uniform, and the distance between the left and right adjacent seedlings 23 is fixed and relatively uniform. Meanwhile, the speed of the present application in the field can be controlled, so that the distance between the front and rear adjacent seedlings 23 can be controlled.
