The conveying shaft (35) drives the spiral feeding blade (34) to rotate. The straw organic fertilizer enters from the straw storage box (31) into the feeding port above the conveying pipeline (38). The spiral feeding blade (34) rotates to convey the fertilizer to the lower port of the conveying pipeline (38), and finally flows into the fertilizer hole drilled by the ground drilling and deep burying device (C).

[0110] Refer to Figures 12 to 14 , the power of the ground drilling and deep burying device (C) is connected by the ground drilling motor (49), and drives the power transmission shaft (39) to rotate through the spline shaft. The power transmission shaft (39) transmits the power to the drill bit (48) through the bevel gear direction-changing box (50). The drill bit (48) rotates accordingly, so as to achieve the purpose of drilling a hole under the soil.

[0111] The bevel gear direction-changing box sleeve (45) is located at the lower end of the ground drilling and deep burying device (C). The front part of the upper end is matched with the transmission shaft sleeve (44), and the rear part is matched with the conveying pipeline (38). The rear part of its lower end adopts an oblique cutting design, which is convenient for the straw organic fertilizer falling from the conveying pipeline (38) to directly fall into the hole drilled by the drill bit (48) without blockage, realizing uniform fertilization.
