Description

Technical Field

[0001] The utility model relates to the technical field of garden pruning, in particular to a garden tree dead branch shearing device. Background Art

[0002] Garden trees refer to woody plants planted and used in gardens, and can also be said to be woody plants suitable for planting and use in urban gardens and scenic spots, including various trees, shrubs and vines. Many garden trees are ornamental trees with beautiful flowers, fruits, leaves, branches or tree shapes. Garden trees also include those species that are not good at beauty, but can play a role in health protection and environmental improvement in the greening of cities and industrial and mining areas and the construction of scenic spots. Therefore, the scope of garden trees is wider than that of ornamental trees. Garden trees will produce a small part of dead branches during their growth, and forest rangers are required to cut the dead branches at this time. At present, the shearing knife of the garden tree dead branch shearing device will become dull after long-term use, thereby affecting the pruning efficiency, so it needs to be disassembled and replaced, but the current process of replacing the shearing knife is relatively cumbersome and the operation is not convenient enough. Therefore, we have launched a new garden tree dead branch shearing device. Utility Model Content

[0003] The main purpose of the utility model is to provide a device for shearing dead branches of garden trees, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A device for shearing dead branches of garden trees comprises a fixed seat, four corners of the lower end of the fixed seat are provided with universal wheels, a storage box is provided on the left part of the upper end of the fixed seat, two cover bodies are provided on the upper end of the storage box, a mounting column is fixedly installed on the right part of the upper end of the fixed seat, a movable groove is provided on the right end of the mounting column, a motor is fixedly installed on the inner lower wall of the movable groove, a threaded rod is fixedly installed on the output end of the motor, a movable block is movably installed on the upper part of the outer surface of the threaded rod, a bearing is provided on the upper part of the outer surface of the threaded rod, an inner groove is provided on the right end of the movable block, a telescopic cylinder is fixedly installed on the right part of the upper end of the movable block, the inner lower wall of the inner groove and the output end of the telescopic cylinder are both provided with fixed blocks, the right ends of the two fixed blocks are both provided with mounting grooves, and shearing mechanisms are movably installed inside the two mounting grooves.

[0006] Preferably, the fixing block located at the upper part is in movable contact with the inner wall of the inner groove.

[0007] Preferably, the front end and the rear end of the movable block are in movable contact with the inner front wall and the inner rear wall of the movable groove.

[0008] Preferably, the upper portion of the outer surface of the threaded rod is movably connected to the inner upper wall of the movable groove via a bearing.

[0009] Preferably, the shearing mechanism includes a mounting block, a limiting groove is provided in the middle of the upper end of the mounting block, a shearing knife is fixedly installed on the right end of the mounting block, a mounting shell is provided at the upper end of the fixed block, a movable rod is movably installed through the middle of the upper end of the mounting shell, a handle is fixedly installed on the upper end of the movable rod, a limiting plate is fixedly installed on the lower part of the outer surface of the movable rod, a spring is movably sleeved on the upper part of the outer surface of the movable rod, and a limiting column is fixedly installed on the lower end of the movable rod.

[0010] Preferably, the upper portion of the outer surface of the spring is fixedly connected to the upper end of the limiting plate and the inner upper wall of the mounting shell.

[0011] Preferably, the output end of the telescopic cylinder is fixedly connected to the upper right portion of the fixed block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the shearing knife becomes dull due to long-term use, turn on the motor through the controller to drive the threaded rod to rotate, so that the movable block moves downward until it moves to the bottom. Pull the handle to make the limit column disengage from the limit groove, so that the internal shearing knife can be quickly removed. When installing a new shearing knife, pull the handle again. At this time, the internal spring is squeezed and contracted due to the force. The mounting block on the left side of the new shearing knife is installed in the mounting groove. Then, the handle is released, and the limit column is clamped in the limit groove by the elastic force of the spring. Therefore, the shearing knife can be quickly fixed, which is convenient for installation and operation.

[0014] 2. Turn on the motor through the controller, and the motor drives the threaded rod to rotate, which in turn drives the movable block to move upward, so that the height of the shearing mechanism can be adjusted according to the growth height of the tree, which is convenient for adjustment and use. By moving the entire device, the dead branches that need to be cut are located between the two shearing knives. Turn on the telescopic cylinder through the controller, so that the upper shearing knife can be driven downward to facilitate the cutting of the branches. No manual cutting is required, which saves time and effort and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
