Description

Technical Field

[0001] The utility model relates to the technical field of power tools, in particular to a saw for selecting branches of trees. Background Art

[0002] A saw, also known as a "power saw", greatly saves the time and labor consumed in cutting materials. The saw uses electricity as power and is a cutting tool used to cut wood, stone, steel, etc. It has sharp teeth on the edge and is divided into a fixed type and a portable type. The saw blade is generally made of tool steel and has various shapes such as circular, strip-shaped, and chain-shaped.

[0003] When most existing saws for selecting branches of trees are in use, in order to cut the branches above the trees, generally, the saw is moved near the branches through an electric air rod, and the selected branches are cut by the saw. However, when cutting the branches, sawdust will spatter along with the saw blade, which easily causes the sawdust to enter the interior of the saw, and thus may cause damage to the internal components of the saw due to the accumulation of sawdust, affecting the normal use of the saw for selecting branches of trees.

[0004] Therefore, the utility model provides a saw for selecting branches of trees to solve the above problems. Content of the Utility Model

[0016] (III) Beneficial effects

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides an electric saw for tree branch selection, as Figures 1 - 5 shown, which includes a driving mechanism. The driving mechanism includes a power supply assembly 12. A power-driven air rod 13 is fixedly connected to the upper surface of the power supply assembly 12. The output end of the power-driven air rod 13 is fixedly connected to a mounting plate 1. A storage box 14 is fixedly connected to one side of the upper surface of the power supply assembly 12. A telescopic rod 15 corresponding to the power-driven air rod 13 is fixedly connected to the upper surface of the storage box 14. A crank 16 is fixedly connected to one side of the storage box 14. One end of the crank 16 is fixedly connected to a torsion rotating shaft 17 that is rotatably connected to the inside of the storage box 14 through a bearing seat. A wire 18 electrically connected to the power supply assembly 12 is wound around the surface of the torsion rotating shaft 17. Through the setting of the torsion rotating shaft 17, when the electric hand saw 3 is used up and reset by the power-driven air rod 13, the crank 16 is rotated, so that the wire 18 is wound around the surface of the torsion rotating shaft 17, thereby avoiding the wire 18 being wound together and affecting the secondary use;

[0027] The wire 18 is slidably inserted into the inside of the telescopic rod 15. The wire 18 is electrically connected to the electric hand saw 3. The wire 18 is slidably connected to the storage box 14. A mounting plate 1 is installed on the surface of the driving mechanism. By starting the power-driven air rod 13, its output end drives the mounting plate 1 to move upward, so that the protective box 2 drives the electric hand saw 3 to move to the selected tree branch;

[0028] A protective box 2 is fixedly connected to the upper surface of the mounting plate 1. An electric hand saw 3 is fixedly connected to the surface of the protective box 2. An adjusting mechanism is installed on the upper surface of the protective box 2. The adjusting mechanism includes a bearing plate 19 fixedly connected to the upper surface of the protective box 2. An adjusting motor 20 is fixedly connected to one side of the bearing plate 19. The output end of the adjusting motor 20 is fixedly connected to an adjusting rod 21. A protective plate 22 corresponding to the electric hand saw 3 is fixedly connected to the surface of the adjusting rod 21. By starting the adjusting motor 20, its output end drives the adjusting rod 21 to rotate, thereby driving the protective plate 22 to flip on the surface of the electric hand saw 3, so that the protective plate 22 is separated from the electric hand saw 3 and no longer protects the electric hand saw 3;

[0029] Support plates 4 are fixedly connected to both edges of the upper surface of the mounting plate 1. A drive motor 5 is fixedly connected to one side of one of the support plates 4. The output end of the drive motor 5 is fixedly connected to a rotating rod 6 that is rotatably connected to the corresponding support plate 4 through a bearing block. A turning plate 7 that is rotatably connected to the support plate 4 is fixedly connected to the surface of the rotating rod 6. Guide plates 8 corresponding to the electric saw 3 are attached to both sides of the turning plate 7. Start the drive motor 5 so that its output end drives the rotating rod 6 to rotate, and thus the turning plate 7 drives the guide plates 8 to rotate, causing the turning plate 7 and the guide plates 8 to disengage from the electric saw 3 synchronously. Through the arrangement of the guide plates 8 and the turning plate 7, when the electric saw 3 cuts the branches, the sawdust generated during the cutting process is blocked, thereby reducing the entry of sawdust into the interior of the electric saw 3 and avoiding the normal use of the electric saw 3 due to the accumulation of sawdust inside the electric saw 3.

[0030] A fixing rod 9 is fixedly connected to the interior of the guide plate 8. One ends of the two fixing rods 9 are jointly rotatably connected to a fixing plate 10. Torsion springs 11 that are fixedly connected to the fixing plate 10 are fixedly connected to the surfaces of the two fixing rods 9. Through the elastic force of the torsion springs 11, after the guide plates 8 are used, the pushing mechanism is reset. The two fixing rods 9 are rotated by the torsion springs 11, thereby causing the guide plates 8 to reset. Thus, through the arrangement of the drive motor 5, the turning plate 7 and the guide plates 8 are reset synchronously to protect the electric saw 3. Therefore, through the mutual cooperation of the turning plate 7, the guide plates 8 and the protective plate 22, the unused electric saw 3 is protected, making the electric saw 3 safer when being stored and placed.

[0031] A pushing mechanism is installed on the upper surface of the fixing plate 10. The pushing mechanism includes a pushing motor 23 fixedly connected to the upper surface of the fixing plate 10. The output end of the pushing motor 23 is fixedly connected to a bidirectional threaded rod 24 that is rotatably connected to the fixing plate 10 through a bearing block. Start the pushing motor 23 so that its output end drives the bidirectional threaded rod 24 to rotate, causing the two pushing plates 25 to move in opposite directions, thereby pushing the two guide plates 8 to rotate on the surface of the fixing plate 10, causing the guide plates 8 to turn over. Pushing plates 25 corresponding to the two guide plates 8 are threadedly connected to both sides of the surface of the bidirectional threaded rod 24.

[0032] Specifically, when the electric saw for tree branch selection is in use: By starting the electric air rod 13, the output end thereof drives the mounting plate 1 to move upward, so that the protective box 2 drives the electric hand saw 3 to move to the selected tree branch. Then start the adjustment motor 20, and its output end drives the adjustment rod 21 to rotate, thereby driving the protective plate 22 to flip on the surface of the electric hand saw 3, so that the protective plate 22 is separated from the electric hand saw 3 and no longer protects the electric hand saw 3. After that, start the drive motor 5, and its output end drives the rotating rod 6 to rotate, so that the turning plate 7 drives the guide plate 8 to rotate, making the turning plate 7 and the guide plate 8 synchronously separated from the electric hand saw 3. At the same time, start the push motor 23, and its output end drives the bidirectional threaded rod 24 to rotate, so that the two push plates 25 move in opposite directions, thereby pushing the two guide plates 8 to rotate on the surface of the fixed plate 10, making the guide plate 8 flip. Thus, through the setting of the guide plate 8 and the turning plate 7, when the electric hand saw 3 cuts the tree branch, the sawdust generated during the cutting process is blocked, thereby reducing the sawdust from entering the interior of the electric hand saw 3 and avoiding the normal use of the electric hand saw 3 being affected due to the accumulation of sawdust inside the electric hand saw 3.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
