Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree pruning equipment and relates to a pruner and a high-yield pruning method for long-fruit mulberry trees. Background Art

[0002] Pruning is a crucial management practice in fruit cultivation, particularly for improving yield and fruit quality in fruit trees like the long-fruit mulberry (Morus macroura). Appropriate pruning can optimize crown structure, increase ventilation and light transmission, promote healthy growth, and effectively reduce the incidence of pests and diseases. However, in practice, pruning presents several challenges, particularly the need for disinfection of diseased and weak branches.

[0003] As a fruit tree with high economic value, long-fruit mulberry trees require regular pruning throughout their growth cycle to remove diseased, weak, dead, and densely intersecting branches to ensure a healthy tree shape and adequate light conditions. These measures help maintain the tree's health, promote the emergence of new shoots, and ultimately increase fruit yield and quality. However, when dealing with diseased trees, to prevent pathogens from spreading to other healthy trees through pruning tools, used tools such as scissors and saws must be strictly disinfected after each pruning.

[0004] Traditional disinfection methods typically involve wiping or soaking tool surfaces with disinfectants. While this method effectively kills most pathogens, it also introduces significant operational inconvenience: time-consuming disinfection steps are required after each diseased tree pruning, reducing overall work efficiency and increasing labor costs. Summary of the Invention

[0005] The object of the present invention is to provide a pruning tool and a high-yield pruning method for long-fruit mulberry trees, which can automatically disinfect the blades while pruning, eliminate the cumbersome disinfection procedure, improve the efficiency of pruning work, and reduce labor intensity.

[0006] In order to solve the above technical problems, the present invention provides a pruning tool, comprising a handle shell, wherein both ends of the handle shell are respectively provided with a battery shell and a transmission shell, a driving motor is provided in the handle shell, a battery is provided in the battery shell, a trimming head is provided at the free end of the transmission shell, a trimming disk is rotatably connected in the trimming head, a plurality of hook-shaped trimming teeth distributed in a circumference are provided outwardly on the edge of the trimming disk, and the bending direction of each hook-shaped trimming tooth is the same, a trimming inlet is provided on one side of the trimming head, and each hook-shaped trimming tooth can be extended into the trimming inlet, two shearing pieces matching the hook-shaped trimming teeth are provided on one side of the trimming inlet, and a gap is left between the two shearing pieces for the hook-shaped trimming teeth to pass through, a driving shaft for driving the trimming disk to rotate is rotatably connected in the handle shell, and a power output shaft of the driving motor is connected to the driving shaft;

[0007] The trimming head is provided with a liquid storage tank, and the bottom of the liquid storage tank extends inwardly to both sides of the hook-shaped trimming teeth and is provided with a dye liquid tank. Each dye liquid tank is provided with a liquid outlet on the side facing the hook-shaped trimming teeth, and each liquid outlet is rotatably connected to a rotating shaft. Each rotating shaft is covered with a water-absorbing dye liquid sleeve that matches the liquid outlet. The size of each water-absorbing dye liquid sleeve can block the liquid outlet to prevent liquid from flowing out. One end of each rotating shaft is provided with a transmission wheel that contacts the trimming disk, and the rotation of the trimming disk can drive the rotation of the transmission wheel.

[0008] By adopting the above technical solution, when pruning, the branches are placed into the pruning entrance, and the driving motor drives the pruning disk to rotate through the driving shaft, driving the hook-shaped pruning teeth to cooperate with the shearing pieces, so that the branches can be cut and pruned. As the pruning disk continues to rotate, the hook-shaped pruning teeth are driven to rotate through the water-absorbing dye liquid sleeve, and the rotating water-absorbing dye liquid sleeve smears the disinfectant on the hook-shaped pruning teeth passing through, thereby disinfecting the surface of the hook-shaped pruning teeth.

[0009] The present invention is further configured such that a worm wheel is provided on one side of the trimming disc, a worm is rotatably connected in the trimming head and meshes with the worm wheel, and the worm is connected to the drive shaft via a coupling.

[0010] The present invention is further configured such that the coupling includes a transmission shaft and two universal joints at both ends of the transmission shaft respectively connected to the drive shaft and the worm.

[0011] The present invention is further configured such that a liquid filling port is provided at the outer end of the liquid storage tank, and the liquid filling port is detachably connected to a sealing cover.

[0012] The present invention is further configured such that a transmission tooth is provided on the outer side of each transmission wheel, and transmission grooves matching with the corresponding transmission teeth are provided on both sides of the edge of the trimming disk.

[0013] The present invention is further configured such that a control button for controlling the operation of the drive motor is provided on one side of the handle shell.

[0014] The present invention is further configured such that the water-absorbing dye liquid is made of a water-absorbing sponge.

[0015] The present invention also provides a high-yield pruning method for long-fruit mulberry trees, using the pruning device according to any one of claims 1 to 7. The pruning is performed in late winter to early spring, that is, before the trees begin to actively grow, or in summer to control the tree shape, thin out overcrowded branches, and remove diseased and weak branches. The method specifically comprises the following steps:

[0016] S1, prepare disinfectant and load it into the liquid storage tank, so that the water-absorbing dye liquid sleeve is completely immersed in the disinfectant;

[0017] S2. Identify branches that are infected by pests and diseases, dead, crossed, parallel, or drooping branches; find last year's fruiting mother branches; find overgrown branches, dead branches, and old branches that are incapable of bearing fruit; and find aging, inactive, and core branches.

[0018] S3, when pruning, the pruning inlet is inserted into the branch to be pruned, the drive motor is started, the pruning disc drives the hook-shaped pruning teeth to rotate and cooperate with the shearing piece to cut the branch, and the hook-shaped pruning teeth after pruning are rotated to the water-absorbing dye liquid sleeve, and the water-absorbing dye liquid sleeve applies disinfectant to the hook-shaped pruning teeth for disinfection;

[0019] S4. For larger cuts, apply an antiseptic or healing agent.

[0020] Further preferably, in step S1, the disinfectant is any one of 75% alcohol or diluted bleach.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] First, when the hook-shaped pruning teeth and the shearing pieces are used to prune branches, the pruning disk rotates to drive the water-absorbing dye sleeve to rotate and absorb the disinfectant, and the disinfectant is applied to the hook-shaped pruning teeth passing by, thereby disinfecting the surface of the hook-shaped pruning teeth. There is no need to disinfect again after each fruit tree is pruned, eliminating the cumbersome disinfection procedure, improving the efficiency of pruning work, reducing labor intensity, and increasing yield.

[0023] Secondly, compared with the traditional method of using a cross-type scissors structure to prune branches, the present invention adopts a method of arranging hook-shaped pruning teeth in a circle on the outer periphery of the pruning disk. The branches are pruned by the cooperation of the continuously rotating hook-shaped pruning teeth and the shearing blades. Compared with the traditional scissor-type pruner, it does not need to be opened and closed for pruning, and can be continuously rotated for pruning, which is convenient for fast and continuous pruning of branches and helps to increase the pruning speed.

A pruning entrance 15 is provided on one side of the pruning head 14, and each hook-shaped pruning tooth 41 can be inserted into the pruning entrance 15. Two shearing blades 5 that cooperate with the hook-shaped pruning teeth 41 are provided on one side of the pruning entrance 15. A gap is left between the two shearing blades 5 for the hook-shaped pruning teeth 41 to pass through. The cooperation between the hook-shaped pruning teeth 41 and the shearing blades 5 can cut and prune branches.

[0031] A drive shaft 6 for driving the trimming disk 4 to rotate is rotatably connected inside the handle shell 1, the power output shaft of the drive motor 2 is connected to the drive shaft 6, a worm gear 42 is provided on one side of the trimming disk 4, and a worm 61 meshing with the worm gear 42 is rotatably connected inside the trimming head 14. The worm 61 is connected to the drive shaft 6 through a coupling to facilitate the spatial arrangement of the drive motor 2. The coupling includes a transmission shaft 62 and two universal joints 63 at both ends of the transmission shaft 62 that are respectively connected to the drive shaft 6 and the worm 61.

[0032] The trimming head 14 is provided with a liquid storage tank 7, the outer end of the liquid storage tank 7 is provided with a liquid filling port 71, the liquid filling port 71 is detachably connected to a sealing cover 72, the bottom of the liquid storage tank 7 extends inwardly to both sides of the hook-shaped trimming teeth 41 and is provided with a dye tank 73, each dye tank 73 is provided with a liquid outlet (omitted in the figure) on the side facing the hook-shaped trimming teeth 41, each liquid outlet is rotatably connected to a rotating shaft 8, and each rotating shaft 8 is outer-coated with a water-absorbing dye sleeve 81 that matches the liquid outlet, and the water-absorbing dye sleeve 81 is made of a water-absorbing sponge. The size of the water dye liquid sleeve 81 can block the liquid outlet to prevent the liquid from flowing out. The water-absorbing dye liquid sleeve 81 absorbs the disinfectant in the dye liquid tank 73 and rotates to apply it on the hook-shaped pruning teeth 41 for disinfection. One end of each rotating shaft 8 is provided with a transmission wheel 82 that contacts the pruning disk 4. The outer side of each transmission wheel 82 is provided with multiple transmission teeth 83.
