[0063] Implementation Process: Before use, first determine the number of tools to be used, selecting one or three tools as the final quantity. If three tools are selected, control the extension end of the folding hydraulic cylinder 12 to extend. At this time, the flipping seat 9 rotates on the side hinge seat 8. At this time, the extension end of the locking hydraulic cylinder 22 is in the extended state, and the locking block extends into the locking groove. The side docking seat 19 cannot move to prevent the side docking seat 19 from not aligning with the main docking seat 18. After flipping, the docking groove aligns with the side docking seat 19. At this time, control the extension end of the adjusting hydraulic cylinder to move. The side rotating shaft 13 slides in the slot and slide, and its tangential movement is restricted by the guide block, which can adjust the distance between the two tools. After docking is completed, control the locking hydraulic cylinder 22 to extend. 2. The telescopic end shortens, causing the locking block to disengage from the slot. At this point, the adjustment is complete. The drive device connected to the universal coupling is controlled to make the universal coupling drive the transmission shaft head and the first and second bevel gears to rotate, ultimately causing the main shaft tube 2 to rotate. The main shaft tube 2 rotates, the main docking seat 18 rotates, and drives the side docking seat 19 to rotate. At this time, the side rotating shaft 13 rotates, causing the first drive sprocket 4 and the second drive sprocket 14 to rotate, ultimately causing the first plow blade and the second plow blade to move. Then, the telescopic end of the tilting hydraulic cylinder is controlled to extend, allowing the three sets of cutters to extend into the soil and begin trenching. The soil brought out is then sent to both sides through the first and second auger drill bits. If only one set of cutters is needed, rotate the spindle tube 2 and rotate the slot to the top. Control the locking hydraulic cylinder 22 to extend the locking block into the slot. At this time, the side docking seat 19 and the side rotating shaft 13 are locked. Then, control the extension end of the folding hydraulic cylinder 12 to shorten, so that the side folding trenching mechanism on both sides is folded to the top of the cover 1. During the folding process, control the rotation of the flipping servo to fold the side folding trenching mechanism on both sides backward to prevent the side cutters from colliding and interfering with the soil when only one set of trenching cutters is needed. Finally, rotate the side folding trenching mechanism onto the bracket 23. Then, control the extension end of the flipping hydraulic cylinder to extend, so that the cover 1 is rotated, allowing only the first plow blade to enter the soil to work.
