Description

Technical Field

[0001] The present invention relates to the technical field of garden maintenance equipment, and more specifically to a tree pruning device for municipal gardens. Background Art

[0002] At present, when garden companies maintain municipal garden trees, they mostly use manual pruning, where workers stand on a crane to take pruning equipment to prune trees. Although this pruning method can complete the pruning work, it also has low pruning efficiency and certain risks when workers prune, which is prone to personal injury accidents. In addition, there are many municipal garden trees, which require efficient pruning operations, which requires the use of suitable pruning tools for different tree branches to maximize pruning efficiency, complete pruning work, and reduce the labor intensity of workers. In view of this, the inventor proposes a tree pruning device for municipal gardens, which realizes the pruning of municipal trees by setting an unmanned pruning device at the end of a crane arm, especially pruning some higher branch forks, and adopts remote control operation, without the need for workers to work at high altitudes, effectively improving the pruning efficiency and realizing the intelligent pruning of municipal garden trees.

[0003] In order to enable the pruning device to be flexibly adjusted according to the growth angle of the tree branches and realize the rapid pruning of branches at different angles, the China Patent Network (CN217363905U) discloses a high-branch pruning device for municipal gardening and landscaping. The utility model includes a mounting plate, a universal wheel is fixedly installed at the lower end of the mounting plate, and a lifting device is fixedly installed at the upper end of the mounting plate. The motor 1 of the utility model drives the moving block to move in the placement groove through the threaded rod. When the moving block moves, the support rod and the cutter move synchronously, so that the cutter is close to the branch to be pruned, and the cutter is started at the same time, so that the branch to be pruned can be quickly pruned; when the angle of the cutter is not suitable for cutting the branch, by starting the motor 2, when the motor 2 drives the gear 1 to rotate, the gear 1 moves under the support rod with the swing rod through the gear 2 and the round rod 2, and the swing rod moves while the cutter moves under the support rod, so as to adjust the cutting angle of the cutter, which is convenient for pruning the branch.

[0004] For example, in order to improve the pruning efficiency, especially for some trees with thicker branches, and reduce the labor intensity of workers, the China Patent Network (CN210247615U) discloses a tree pruner for municipal garden maintenance. The utility model includes a support plate, a forward and reverse motor is fixedly installed on the left side of the top of the support plate, a first bevel gear is fixedly installed on the top of the output shaft of the forward and reverse motor, a transmission device is fixedly installed on the top of the support plate and located on the right side of the forward and reverse motor, the left side of the transmission device is meshed with the first bevel gear, and a movable bearing is fixedly installed in the middle of the top of the support plate. The utility model can make the threaded rod rotate by setting the forward and reverse motor and the transmission device, and then drive the moving plate to move up and down, so that the pruning height of the pruner can be adjusted, making it more convenient to prune tall trees, and a hydraulic rod is provided to further increase the pruning height of the pruner. By setting the pruning device, thicker branches can be pruned, making the pruning process more labor-saving and convenient.

[0005] The above two solutions still have some shortcomings in application. First, municipal trees are thick and thin. Saws are most suitable for thick branches, and scissors are most suitable for thin branches. Therefore, using different tools to prune different branches can improve maintenance efficiency and save time. Second, the level of intelligence is improved. Since many municipal trees have a certain height, if workers need to stand on the pruning device when pruning, it is an aerial operation, which is dangerous and needs to be avoided as much as possible. Therefore, it is necessary to improve the structure of the tree pruning device so that it can prune trees quickly without the need for workers to work at high altitudes, thereby improving the intelligence level and practicality of the device. Summary of the invention

[0006] The present invention discloses a tree pruning device for municipal gardens, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the prior art.

[0020] The specific implementation of the present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, a tree pruning device for municipal gardens includes a pruning basket 1 and a remote control 2. A first cavity 3 is provided on the front side of the pruning basket 1, and a first cylinder 31 is installed in the first cavity 3. The driving end of the first cylinder 31 is upward and a first turntable 32 is installed at the end. A sawmill 33 is installed on the first turntable 32. A second cavity 4 is provided on the left side of the pruning basket 1, and a second cylinder 41 is installed in the second cavity 4. A pruning knife 5 is installed above the second cavity 4, and a lower handle 51 of the pruning knife 5 abuts against the second cylinder 41. A third cavity 6 is provided on the rear side of the pruning basket 1, and a circuit board 61 and a camera 62 are installed on the inner side and the top of the third cavity 6 respectively. The circuit board 61 is respectively controlled and connected to the sawmill 33, the first cylinder 31, the second cylinder 41 and the camera 62.

[0022] Furthermore, a hanging arm 7 is adaptively provided on the rear side of the trimming basket 1 .

[0023] Furthermore, the driving end of the first cylinder 31 is upward, and the sawmill 33 can be lifted upward by the first cylinder 31 and can be rotated left and right by the first turntable 32 .

[0024] Furthermore, the first cavity 3 has a built-in motor 8, the driving end of the motor 8 is facing left and the end is equipped with a first gear 81, the end of the upper handle 52 of the trimming knife 5 is equipped with a second gear 53, the second gear 53 is adapted to mesh with the first gear 81, and the trimming knife 5 can be rotated up and down along the end of the upper handle 52 of the trimming knife 5 through the motor 8.

[0025] Furthermore, the camera 62 is provided with a base 9 , and a second turntable 91 is mounted on the base 9 , and the camera 62 can rotate via the second turntable 91 .

[0026] Furthermore, a wireless communication device 10 is provided on the top rear side of the third cavity 6 , and the wireless communication device 10 is communicatively connected with the remote controller 2 .

[0027] Furthermore, a display screen 21 is provided in the middle of the remote controller 2 , and the display screen 21 is display-connected to the camera 62 .

[0028] [Example 1] First, the pruning basket 1 is lifted to the side of the branch to be pruned by the lifting arm 7, so that the sawmill 33 is at a corresponding height with the branch to be pruned. Then, the status of the sawmill 33 is checked through the camera 62, and the height and angle of the sawmill 33 can be fine-tuned by the first cylinder 31 and the first turntable 32. The operator can check in real time through the display screen 21 of the remote control 2. After determining the height and angle, the sawmill 33 is started to saw the branch. Finally, after the sawing is completed, the pruning basket 1 is moved by the lifting arm 7 to prune the next branch. This method is suitable for pruning branches with a larger diameter.

[0029] [Example 2] First, the pruning basket 1 is lifted to the side of the branch to be pruned by the lifting arm 7, and the first gear 81 is driven to rotate by the motor 8, and the first gear 81 drives the second gear 53 to rotate. The second gear 53 rotates to rotate the blade head of the pruning knife 5 from top to front. At this time, the blade head of the pruning knife 5 is facing the front. Then, the position of the branch to be pruned is checked through the camera 62, and the angle between the upper handle 52 and the front side of the lower handle 51 of the pruning knife 5 is inserted into the branch to be pruned, and the second cylinder 41 is started to drive the lower handle 51 of the pruning knife 5 upward so that the front side of the blade of the pruning knife 5 bites to achieve the pruning of the branch.
