[0028] Please refer to Figures 1-4 , an embodiment provided by the present utility model:
[0029] A tree pruning device for greening projects, which includes:
[0030] A box body 1, on both sides of the bottom of the box body 1, symmetrically distributed universal wheels 2 are fixedly installed. On one side of the box body 1, a fixed frame 8 is fixedly installed. Inside the fixed frame 8, a fixed rod 9 is provided. At the top of the fixed rod 9, a movable rod 10 is movably inserted. At the bottom inside the fixed rod 9, a second motor 20 is fixedly installed. The driving end of the second motor 20 is fixedly installed with a threaded rod 19;
[0031] On the lower sides of both outer walls of the movable rod 10, limit blocks 18 are fixedly installed. On the inner wall of the fixed rod 9, symmetrically distributed limit grooves 17 are opened, and the limit grooves 17 are slidably connected to the corresponding limit blocks 18. On the front of the fixed frame 8, a fixed groove 13 is opened. On the lower side of the outer wall of the fixed rod 9, a handle 15 is fixedly installed, and the handle 15 penetrates inside the fixed groove 13. Inside the box body 1, a storage battery 3 is fixedly installed. On one side of the front of the box body 1, a wire hole 14 is opened;
[0032] The storage battery 3 is electrically connected to a wire 16, and the wire 16 penetrates inside the wire hole 14. At the top of the movable rod 10, a first motor 12 is fixedly installed. The driving end of the first motor 12 is fixedly installed with a cutting disc 11. The storage battery 3 is electrically connected to the second motor 20 and the first motor 12 through the wire 16 respectively. The wire 16 has sufficient length to ensure the adjustment range of the device when the staff holds and uses the device.
[0033] Inside the box body 1, above the storage battery 3, a positioning frame 4 is fixedly installed. On the top of the positioning frame 4, a partition plate 5 is provided.
[0034] In one of the embodiments, on both the front and the back of the box body 1, a pusher 7 is fixedly installed, which facilitates the staff to easily push the device to move both in front of and behind the device, improving the convenience of people's use.
[0035] In one of the preferred embodiments, on the top of the box body 1, a movable cover plate 6 is provided, which plays a role in closing the top of the box body 1 to prevent external impurities and dust from entering the inside of the box body 1 during the pruning process.
[0036] In one embodiment, the handle 15 is in sliding contact with the inner wall of the fixing groove 13. After the fixing rod 9 is inserted into the fixing frame 8, the handle 15 is limited by the fixing groove 13 to prevent the fixing rod 9 from rotating inside the fixing frame 8, thereby improving the stability of the cutting disc 11 during the pruning process.
[0037] In one preferred embodiment, a thread groove adapted to the threaded rod 19 is provided on the inner wall of the movable rod 10, and the movable rod 10 is threadedly sleeved on the outer wall of the threaded rod 19 through the thread groove provided on its inner wall.
[0038] The working principle of the present utility model is as follows: The electrical components appearing in this application are externally connected to the control switch on the outer surface of the fixing rod 9 during use. When the device is in use, the staff can directly push the device in any direction by the rolling contact of the universal wheels 2 with the ground. The movement of the box body 1 will drive the fixing rod 9 inserted inside it through the fixing frame 8. The fixing rod 9 drives the first motor 12 to move through the movable rod 10, and the cutting disc 11 follows the first motor 12 to move. After the whole device is pushed near the tree, the first motor 12 and the second motor 20 can be controlled to start working. The driving end of the first motor 12 drives the cutting disc 11 to rotate. When the rotating cutting disc 11 approaches the tree, it will directly cut off the branches. For some branches at a higher height, after the second motor 20 starts working, the driving end of the second motor 20 drives the threaded rod 19 to rotate. Through the threaded transmission between the threaded rod 19 and the movable rod 10, and the sliding relationship between the movable rod 10 and the limiting groove 17 through the limiting block 18, the movable rod 10 moves vertically stably. The movement of the movable rod 10 drives the first motor 12 to move, and the movement of the first motor 12 drives the cutting disc 11 to move. Thus, through the drive of the second motor 20, the height of the cutting disc 11 can be changed, which is convenient for pruning some higher branches. When pruning branches with a more tricky angle, the staff can directly remove the fixing rod 9 from the fixing frame 8 through the handle 15 and use the fixing rod 9 by hand. At this time, the change of the angle of the cutting disc 11 will be more flexible, which is convenient for pruning some trees with a more tricky angle. During the use of the device, it can be used in combination with the box body 1 with a moving function, or the pruning mechanism can be directly used by hand, ensuring the flexibility during use, reducing the burden on the staff, and improving the pruning efficiency. In addition, through the setting of the storage battery 3 inside the box body 1, enough installation space is provided for the storage battery 3, and it is convenient to move, which can ensure the energy supply of the device during use and improve the endurance of the device.
[0039] Above the internal battery 3 in the box body 1, the internal space of the box body 1 is divided into upper and lower spaces by the positioning frame 4 and the partition plate 5. At the top of the partition plate 5, the staff can place some tools or their own supplies, which improves the storage space of the device and meets the usage requirements of people.
[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
