Technical Field

[0001] The utility model relates to the technical field of fruit tree pruning, in particular to a portable electric fruit tree pruning device. Background Art

[0002] Fruit tree pruning is an important horticultural management technique, which is crucial to improving the yield and quality of fruit trees and maintaining the health and long-term productivity of trees. Through pruning, the distribution of branches and leaves inside and outside the crown can be adjusted to ensure that light can evenly irradiate the inside of the crown, improve photosynthesis efficiency, promote fruit ripening and color development, and control the balance between vegetative growth and reproductive growth, avoiding excessive vegetative growth that consumes too many nutrients and affects fruit yield and quality.

[0003] At present, when pruning fruit tree branches, scissors and other tools are usually used to cut off the excess branches. After pruning the fruit tree branches, it is very necessary to properly treat the wounds to prevent the invasion of pathogens, reduce water evaporation, and promote wound healing. However, most of the existing technologies manually apply drugs to the wounds after pruning, which is troublesome and laborious.

The front side of the upper part of the telescopic rod is connected to the fixed frame, the lower side of the fixed frame is connected to the servo motor, the servo motor output shaft is connected to the screw rod, the left and right parts of the fixed frame are rotatably connected to the spreading piece, the stretching assembly is connected between the spreading piece and the screw rod, the stretching assembly includes a moving block and a connecting plate, the moving block is threadedly connected to the screw rod, the left and right parts of the moving block are rotatably connected to the connecting plate, the ends of the connecting plates are rotatably connected to the adjacent spreading pieces, the servo motor output shaft rotates to drive the screw rod to rotate, the screw rod rotates to drive the moving block to move up and down through the thread, the moving block moves through the connecting plate to drive the spreading piece to rotate on the fixed frame to spread the remaining branches around.

[0012] The beneficial effects are: 1. During the pruning process, the utility model transports the medicine in the medicine box to the nozzle through the infusion tube, and then sprays the medicine onto the wounds of the pruned branches through the nozzle, thereby applying the medicine to the wounds of the branches. It can achieve the effect of directly spraying the medicine on the wounds of the branches during the pruning process, which is more convenient and labor-saving.

[0013] 2. The utility model drives the screw to rotate by rotating the output shaft of the servo motor. The rotation of the screw drives the moving block to move upward through the thread. The movement of the moving block drives the spreading piece to rotate on the fixed frame through the connecting plate to spread the remaining branches around, thereby avoiding accidental cutting of the remaining branches around.
