Each rotating assembly is located at a pruning knives 35. The rotating assembly can drive the pruning knife 35 to rotate around the axis of the mounting ring 24 while rotating on itself, that is, the pruning knife 35 can achieve rotary cutting when rotating around the axis of the pruning knife 35, so as to prune the low wood. At the same time, when the pruning knife 35 revolves around the axis of the mounting ring 24, the pruning knife 35 can prune the whole low wood, and the pruning is more comprehensive. Each sorting assembly is located on one side of a pruning knife 35, and the sorting assembly can sort the low wood at the trimmed position to ensure that the low wood at the trimmed position can be gathered, which is beneficial for the pruning knife 35 to trim the low wood and ensure the pruning effect.

[0040] like Figure 1-Figure 6 As shown, the telescopic assembly includes a dual-axis motor 22, two through slots 17, two strip slots 18, two insertion rods 19, two moving blocks 20, two screw rods 21 and two mounting plates 23;

[0041] Two through slots 17 are symmetrically provided at both ends of the lifting rod 16, each strip slot 18 is provided at the top end of the lifting rod 16 and is connected to a through slot 17, each insertion rod 19 is inserted into the inside of a through slot 17, the insertion rod 19 is slidably provided inside the through slot 17, the insertion rod 19 can be extended and retracted inside the through slot 17, the other end of each insertion rod 19 is fixedly connected to a mounting ring 24, each moving block 20 is slidably provided inside a strip slot 18, each moving block 20 is fixed to one end of a insertion rod 19 away from the mounting ring 24, the dual-axis motor 22 is fixedly installed in the middle of the top end of the lifting rod 16, the two mounting plates 23 are fixed on both sides of the top end of the lifting rod 16, the two screw rods 21 are symmetrically fixed to the two output ends of the dual-axis motor 22, each screw rod 21 passes through a moving block 20 and is rotatably connected to a mounting plate 23, and each screw rod 21 and the moving block 20 are threadedly matched;

[0042] When it is necessary to adjust the distance between the two mounting rings 24, the dual-axis motor 22 is controlled to work, and the dual-axis motor 22 can drive the two screw rods 21 to rotate synchronously. Since the screw rod 21 and the moving block 20 are threadedly matched, and the moving block 20 is slidably set inside the strip groove 18, when the screw rod 21 rotates, it can drive the moving block 20 to slide inside the strip groove 18, thereby driving the insertion rod 19 to slide inside the through groove 17, and then driving the mounting ring 24 to move, thereby adjusting the position between the two mounting rings 24, and ensuring that the two mounting rings 24 are respectively located above two adjacent low woods, so as to facilitate the subsequent pruning of the low wood.

[0043] like Figure 1-Figure 6 As shown, each rotating assembly includes a gear ring 25, a mounting frame 26, a single-axis motor 27, a first gear 28, a second gear 29 and a rotating shaft 33;
