Description

Technical Field

[0001] This application relates to the field of cherry cultivation technology, and in particular to a branch-pulling device for cherry cultivation. Background Technology

[0002] In cherry cultivation, branch-pulling devices are used to control the growth direction and angle of branches during fruit tree shaping and pruning. These devices promote the formation of an ideal canopy structure through physical constraints and mechanical principles. Their core function is to fix and adjust branches using tension lines, support structures, or elastic elements to improve ventilation and light penetration, promote flower bud formation, and control excessive vegetative growth.

[0003] Patent document CN210840792U discloses a branch-pulling device for cherry cultivation, including a sleeve with a protective pad on its inner wall. A rope is connected to a fine-tuning device, which in turn is connected to a pull rope. The end of the pull rope away from the fine-tuning device is wound around a take-up roller, which is rotatably connected to the inner wall of a take-up box. A handle is located on the left side of the take-up box, penetrating the left side wall and connected to the take-up roller. A bolt is mounted on the handle. A connecting rope is located at the upper end of the take-up box, with its end away from the take-up box tied to a belt. The belt has a male buckle and a female buckle. This branch-pulling device for cherry cultivation secures the sleeve to the cherry tree trunk via a first buckle and a first snap fastener, facilitating rope fixation, reducing the use of tree stumps, and allowing selection of an appropriate number of branches to be pulled based on the number of branches needed for a single cherry tree. The sleeve is then secured to the sleeve via a second snap fastener.

The lifting rod 13 is fixedly connected to the circular plate 15.

[0042] The buckling device includes two fixing blocks 21, both of which are fixedly connected to the circular plate 15. Each of the two fixing blocks 21 is embedded with a fixing rod 2, and both fixing rods 2 are fixedly connected to the support frame 4.

[0044] The implementation principle of the cherry cultivation branch pulling device in this embodiment is as follows: In use, twisting the four twisting blocks 8 drives the four screws 12 to rotate, and the four screws 12 drive the four clamping blocks 11 and the four telescopic rods 10 to move, clamping and fixing the thicker branches at the bottom.
