[0013] The intelligent self-sequence seedling throwing and planting device has the following advantages over the prior art:

[0014] Under the action of the seedling puller, the seedlings enter the first belt conveyor from the seedling box. Because the rotation direction of the first seedling comber is opposite to that of the first belt conveyor, but their rotation speed is the same, the seedlings are blocked by the first comber and pass through the gap between the first belt conveyor and the first comber, falling onto the second belt conveyor, thus achieving initial dispersion of the seedlings. After this initial dispersion, the seedlings are evenly distributed and conveyed on the first belt conveyor. Due to the inclined installation of the first belt conveyor, the seedlings are thrown upwards as they leave, with larger clumps falling onto the second comber. Because the rotation speed of the second comber is lower than that of the second belt conveyor, and its rotation direction is opposite, the second comber further disperses some of the larger clumps of seedlings. Since the weight of the roots is greater than the weight of the stems, and under the airflow of the second comber, the seedlings fall onto the second belt conveyor with the stems behind and the roots in front, achieving initial posture adjustment and secondary dispersion of the seedlings. After initial seedling posture adjustment and a second dispersion, the seedlings are intelligently and orderly distributed evenly on the second belt conveyor. Because the blower's outlet is upward, the seedlings leave the second belt conveyor and fall into the trays, being thrown upwards. Since the weight of the roots is greater than the weight of the stems, and the blower's outlet is blowing upwards, the seedlings follow a parabolic trajectory, landing in the field with the stems above and the roots below, thus achieving the transplanting operation. Therefore, the seedlings undergo initial dispersion, second dispersion, initial posture adjustment, and second posture adjustment during the transplanting process, ensuring the stability and uniformity of the transplanting posture, achieving intelligent and orderly transplanting, and improving transplanting efficiency.

Experiments have proved that the above technical parameters can ensure the stability and uniformity of the throwing planting posture, realize intelligent and orderly seedling throwing, and improve the throwing planting efficiency.

[0025] As shown in Figure 2 The first seedling comb 4 includes a first comb shaft 40 and at least two poking rods 41, the at least two poking rods 41 are uniformly installed in the circumferential direction of the first comb shaft 40, and each poking rod 41 is installed in the transverse direction along the axial extension of the first comb shaft 40.

Since the weight of the root of the seedling is greater than that of the stem, and under the rotating airflow of the second seedling combing machine 6, the seedlings fall on the second belt seedling conveying machine 7 with the stem in the rear and the root in the front, realizing the preliminary attitude adjustment and the second dispersion of the seedlings. After the preliminary attitude adjustment and the second dispersion, the seedlings are regularly and uniformly distributed on the second belt seedling conveying machine 7 and conveyed. Since the air outlet 80 of the air blower is upward, the seedlings fall into the pot 81 after leaving the second belt seedling conveying machine 7 and are thrown upward. Since the weight of the root of the seedling is greater than that of the stem, and the air outlet 80 of the air blower is upward, the air speed of the air outlet 80 of the air blower is 45 m / s, the oblique angle R2 of the air outlet 80 of the air blower is 45 degrees, and the seedlings have a parabolic trajectory, the seedlings fall in the field with the stem upward and the root downward, realizing the throwing planting operation of the seedlings. Therefore, the seedlings undergo the preliminary dispersion, the second dispersion, the preliminary attitude adjustment, and the second attitude adjustment during the throwing planting process, which can ensure the stability and uniformity of the throwing planting attitude, realize the intelligent and orderly throwing of the seedlings, and improve the throwing planting efficiency.
