Description

Technical Field

[0001] The utility model relates to the technical field of gardening and greening, in particular to a pruning device with adjustable height. Background Art

[0002] Landscape architecture is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, transforming the terrain (or further building mountains, stacking stones, and managing water), planting trees, flowers, and plants, creating buildings, and arranging garden paths. Landscape architecture includes courtyards, residential gardens, small gardens, flower gardens, parks, botanical gardens, zoos, etc. With the development of landscape architecture, it also includes forest parks, scenic spots, tourist areas of nature reserves or national parks, and recreational resorts.

[0003] The utility model patent with the authorization announcement number CN218277928U discloses a height-adjustable tree pruning device, which includes a bottom plate, a lifting mechanism and a cutting mechanism. The lifting mechanism includes a lifting sleeve, and the bottom of the inner wall of the lifting sleeve is fixedly connected to a first servo motor. The utility model, through the cooperation between the lifting mechanism and the cutting mechanism, on the one hand, does not require the staff to hold the pruning tool to lift the tree branches to prune, which reduces the fatigue of the staff, thereby improving the staff's work efficiency in pruning the tree branches. On the other hand, the cutting disc is used to prune the tree branches. Compared with the staff holding the pruning tool to prune the tree branches, the cutting disc is more labor-saving in cutting tree branches of different thicknesses, thereby reducing the time spent by the staff in pruning the tree branches, and further improving the staff's work efficiency in pruning the tree branches.

[0004] Although the above utility model can conveniently allow staff to prune the branches of trees, in actual use, in addition to pruning the side branches, there are also trees that need to be pruned at the top. In view of this, we propose a pruning device with adjustable height. Utility Model Content

Through the above mechanism, the angle of the pruning mechanism 310 can be conveniently adjusted, so that the pruning mechanism 310 can prune branches at different positions.

[0028] Furthermore, a rotating plate 35 is welded on the right side surface of the rotating rod 36 , a rotating handle 34 is welded on the right side surface of the rotating plate 35 , and a plurality of positioning holes 39 are opened at the right end of the outer side surface of the rotating rod 36 , and the rotating rod 36 can be positioned by cooperating with the fixing hole 32 through the positioning holes 39 .

[0030] In this embodiment, the water spray mechanism 4 includes a water tank 41 and a water pump 42 installed on the top of the water tank 41. The water outlet of the water pump 42 is installed with a connecting water pipe 43. The top of the connecting water pipe 43 is connected to an auxiliary block 44. A fixed water pipe 45 is installed on the left surface of the auxiliary block 44. A nozzle 46 is installed at the end of the fixed water pipe 45 to prevent waste chips from splashing during cutting.

[0031] In this embodiment, there are six positioning holes 39 , which are divided into two groups, with three holes in each group. The two groups of positioning holes 39 are perpendicular to each other, so that the trimming mechanism 310 can be in both horizontal and vertical states.

[0032] In this embodiment, the rotating plate 35 is a square in side view, and the length of the rotating plate 35 is equal to the height of the fixed block 31 , so that the rotation degree of the rotating rod 36 can be easily determined through the rotating plate 35 .

[0033] In this embodiment, the rotating handle 34 is synchronously in a vertical or horizontal state with the cutting knife in the trimming mechanism 310 , and the left and right surfaces of the connecting block 38 are provided with anti-slip grooves to facilitate gripping of the connecting block 38 .

[0036] During the specific use of the height-adjustable pruning device of this embodiment, if it is necessary to trim the side branches, the moving handle 13 is held to push the entire device to the lower side of the cutting position, and then the control mechanism 3 is raised by the lifting mechanism 2, and then the pruning mechanism 310 is started to prune the branches;

[0037] If it is necessary to prune the top branches, it is necessary to first hold the connecting block 38 to pull the limiting rod 37 out of the positioning hole 39 and the limiting hole 33, then hold the rotating handle 34 and rotate the rotating handle 34 90°, so that the rotating rod 36 and the pruning mechanism 310 will also rotate 90°, which will change the pruning mechanism 310 from a vertical state to a horizontal state, and then reinsert the limiting rod 37 into the positioning hole 39 and the limiting hole 33 to complete the fixation, then start the pruning mechanism 310, and then hold the moving handle 13 to push the device body to prune the top of the branch.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
