[0022] This utility model embodiment provides a fruit tree pruning device, such as... Figure 1-5As shown, the fruit tree pruning device includes: a sleeve 1, on which a rectangular rod 2 is slidably mounted, and the rectangular rod 2 has multiple slots; a bolt 3 threaded onto the sleeve 1, the bolt 3 being adapted to any one of the slots; a housing 4 welded to the rectangular rod 2, on which a box 5 is hinged, and the box 5 has an opening; two gears 7 rotatably mounted on the box 5 via two rotating shafts 6, each of the two gears 7 having a fixed blade 8 for pruning fruit tree branches and leaves, both blades 8 being located inside the opening; two protective sleeves 9 fixedly mounted on the box 5 to cover the two blades 8; a drive mechanism mounted on the box 5 for rotating the two blades 8; and an angle adjustment mechanism mounted on the housing 4 for rotating the box 5.
[0023] In this embodiment, during fruit tree planting, if the device is to be used to prune the branches and leaves of the fruit trees, first, rotate bolt 3 by hand to disengage it from the inserted slot. After disengagement, the rectangular rod 2 can slide on the sleeve 1. The length of the device can be adjusted according to the pruning requirements. After adjustment, rotate bolt 3 in the opposite direction. Since bolt 3 is threadedly connected to sleeve 1, it can be inserted into the corresponding slot on the rectangular rod 2. After insertion, the rectangular rod 2 can be fixed on sleeve 1. Then, hold sleeve 1 and lift the entire device, aligning the two blades 8 with the branches and leaves to be pruned. If the angle of the two blades 8 needs to be adjusted due to obstruction by branches, it can be adjusted by... An angle adjustment mechanism drives the housing 5 to rotate on the shell 4. As the housing 5 rotates, the angles of the two blades 8 also change. Once the two blades 8 are adjusted to the appropriate angle, they can be easily aligned with the branches and leaves to be pruned. Then, the drive mechanism is activated, which drives the two gears 7 to rotate. The two gears 7 drive the two blades 8 to move closer to each other until the pruning of the branches and leaves is completed. After pruning, the drive mechanism returns the two gears 7 and the two blades 8 to their original state, allowing the two blades 8 to enter the two protective sleeves 9. Under the protection of the two protective sleeves 9, the two blades 8 can be effectively prevented from being accidentally touched when not in use, greatly reducing safety hazards.
[0024] In a further preferred embodiment of the present invention, the driving mechanism includes: an electric push rod 10 fixedly installed on the inner wall of the housing 5, and an installation block 11 fixedly installed on the output rod of the electric push rod 10; two racks 12 fixedly installed on the installation block 11, and the two racks 12 respectively meshing with the two gears 7.
[0025] In this embodiment, the drive mechanism is used to rotate the two blades 8. When in use, the electric push rod 10 is activated, which drives the mounting block 11 to move. The mounting block 11 drives the racks 12 on both sides to rotate the two gears 7. The two gears 7 drive the two blades 8 to move closer to each other until the pruning of the branches and leaves is completed. After the pruning is completed, the electric push rod 10 is activated to drive the mounting block 11 to move in the opposite direction, which can unfold the two blades 8 and allow them to be hidden in the two protective sleeves 9.
[0026] In a further preferred embodiment of the present invention, the angle adjustment mechanism includes: a servo motor 13 fixedly installed on the inner wall of the housing 4, a screw 14 fixedly installed on the output shaft of the servo motor 13; a slider 15 threadedly installed on the screw 14, a hinge rod 16 hinged to the slider 15, and one end of the hinge rod 16 hinged to one side of the housing 5.
[0027] In this embodiment, the angle adjustment mechanism is used to rotate the housing 5. During adjustment, the servo motor 13 is started to drive the screw 14 to rotate. The screw 14 will drive the slider 15 to move. The slider 15 will drive the housing 5 to rotate on the shell 4 through the hinge rod 16. Thus, even when the device is blocked by branches, the use angle of the two blades 8 can be adjusted to a suitable position. When the two blades 8 are adjusted to a suitable angle, it is easy to align the two blades 8 with the branches and leaves that need to be pruned, making the adjustment more convenient.
[0028] In a further preferred embodiment of the present invention, limiting plates 17 are fixedly installed on both sides of the mounting block 11, and limiting rods 18 are slidably installed on both limiting plates 17, with one end of each limiting rod 18 fixedly connected to the inner wall of the box 5.
[0029] In this embodiment, the stability of the mounting block 11 during movement can be ensured by the combined use of two limiting plates 17 and two limiting rods 18. While the mounting block 11 is moving, the limiting plates 17 connected to the mounting block 11 will also slide on the limiting rods 18.
[0030] In a further preferred embodiment of the present invention, a sliding groove is provided on the inner wall of the housing 4, and a limiting block 19 is slidably installed on the inner wall of the sliding groove. One side of the limiting block 19 is fixedly connected to the slider 15.
[0031] In this embodiment, the inner wall prevents the slider 15 from rotating during movement by using the sliding groove and the limiting block 19 together. During the movement of the slider 15, the limiting block 19 connected to the slider 15 will also slide in the sliding groove.
[0032] In a further preferred embodiment of this utility model, a knob is fixedly installed at one end of the bolt 3, and multiple anti-slip strips are fixedly installed on the outer wall of the sleeve 1.
[0033] In this embodiment, the use of the knob allows personnel to easily rotate the bolt 3, and the use of multiple anti-slip strips can increase the friction of the sleeve 1 surface, making it less likely for personnel to slip when holding the sleeve 1.
[0034] In a further preferred embodiment of the present invention, a groove is provided on the inner wall of the housing 4, and a bearing is fixedly installed on the inner wall of the groove, and the inner ring of the bearing is fixedly connected to the screw 14.
[0035] In this embodiment, the use of bearings enables the screw 14 to remain stable during rotation, reducing the possibility of shaking.
[0036] In summary, compared with related technologies, this solution, through the use of bolts 3, allows personnel to easily adjust the position of the rectangular rod 2 on the sleeve 1 according to the needs of pruning branches and leaves, thereby adjusting the overall length of the device. The use of the angle adjustment mechanism allows for adjustment of the operating angles of the housing 5 and the two blades 8 when the device is obstructed by branches, enabling the device to accurately prune specific branches and leaves among complex tree branches. The drive mechanism allows the two blades 8 to move closer or further apart. When closer, the two blades 8 can prune the branches and leaves of the fruit tree; when further apart, the two blades 8 are hidden within the two protective sleeves 9. This effectively prevents the two blades 8 from being accidentally touched when not in use, greatly reducing safety hazards.
