[0067] The device is pushed from the pushing hand 11, and under the limiting connection of the transmission block 57 and the connecting protrusion 15, the rotation of the rear wheel 14 drives the transmission block 57 to rotate, and the transmission block 57 drives the bevel gear two 46 to rotate the bevel gear one 43 under the connection of the transmission belt 47, so that the rotating sleeve plate 44 connected with the guide outer groove 41 slides to move vertically, and the connecting rod 39 is driven by the connecting sliding block 45 to move vertically downward while the rotating sleeve plate 44 is lowered, so that the connecting sleeve block 36 is moved outward and downward under the elastic adaptation of the connecting corrugated pipe 31, and the connecting sleeve block 36 is moved outward and downward under the vertical guide groove and the spiral sliding groove connection of the connecting sliding block and the guide inner groove 34, and the hole drill bit 37 is rotated and the soil beside the corn seedling is drilled when the connecting sleeve block 36 is moved to the spiral sliding groove, and when the rotating sleeve plate 44 slides with the guide outer groove 41 to return, the connecting sleeve block 36 is driven to return at the same time, and the controller in the closing control block 38 starts to release the sealing state of the bottom end of the hole drill bit 37, and the fertilizer in the fertilizer bin 3 is accurately injected into the hole, and the controller in the closing control block 38 starts to close the bottom end of the hole drill bit 37 when the connecting sleeve block 36 moves to the vertical guide groove section, and the fertilizer drilling and injection are completed.

[0068] When moving adjustment is performed, the connecting vertical plate 6 will simultaneously push the abutting rotating wheel 61 to ensure the tensioning abutment of the transmission belt 47, so that the normal transmission of the transmission mechanism is realized, then the abutting rotating wheel 61 drives the rotating rod 62 to rotate when the device is started, and the horizontal reciprocating movement along the connecting sliding sleeve plate 65 is realized under the transmission of the sector gear 63 and the connecting rack plate 64, then the bottom end of the smoothing scraper 68 will be well matched with the soil under the rotating connection of the inclined slot 67 and the smoothing scraper 68 in the reciprocating movement process, and the soil drilled out is smoothed and backfilled.
