The straw organic fertilizer enters the feed port above the conveying pipeline (38) from the straw storage box (31), and the spiral conveying 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 deep-buried drilling device (C).

[0112] See also Figure 12 to Figure 14 The power of the deep-buried earth drilling device (C) is connected to the earth drilling motor (49), which 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 change box (50), and the drill bit (48) rotates accordingly, thereby achieving the purpose of drilling a hole under the soil.

[0113] The bevel gear change-direction box sleeve (45) is located at the lower end of the ground drilling deep-buried device (C), the front part of the upper end cooperates with the transmission shaft sleeve (44), and the rear part cooperates with the conveying pipeline (38). The rear part of the lower end adopts an oblique cutting design, which facilitates the straw organic fertilizer falling from the conveying pipeline (38) to directly fall into the hole drilled by the drill bit (48) without clogging, thereby achieving uniform fertilization.
