Description

Technical Field

[0001] This utility model relates to the technical field of pear tree pruning, and more specifically, it relates to a pruning device for pear tree planting. Background Technology

[0002] Pruning pear trees is a very important cultivation and management technique. Proper pruning can form a good tree structure, improve ventilation and light conditions, reduce pests and diseases, and balance vegetative and reproductive growth, thereby achieving the goal of high-quality and high-yield year after year. In the process of pruning pear trees, a pruning device is needed.

[0003] However, traditional pruning devices are mostly scissor-type, which requires manual pressing of the scissors, which is time-consuming and laborious. They are not suitable when processing thicker branches.

[0004] Furthermore, traditional pruning devices are mostly fixed angles, making it difficult to flexibly adjust the angle of the upper pruning components during the pruning of pear trees. This results in incompatibility when pruning branches at different angles. Utility Model Content

[0031] In this embodiment, a housing 12 is fixedly provided on the outer wall of the connecting frame 11. A second motor 13 is provided inside the housing 12. Gears 14 are provided on both the output end of the second motor 13 and the fixed shaft 10. The two gears 14 are meshed and installed. A protective cover 15 is provided on the outer side of the gears 14 and on the outer wall of the housing 12. Heat dissipation holes 24 are provided on the outer wall of the housing 12.

[0032] More specifically, the user can control the first motor 3 to make its output end drive the mounting sleeve 4 and mounting rod 5 to rotate, so that the saw blade 6 rotates. Then, the saw blade 6 contacts the pear tree branch that needs to be pruned, thereby achieving the pruning effect. Afterwards, the pin 8 can be removed from the insertion hole 7 by removing the fastening nut 9, so as to facilitate the disassembly and replacement of the saw blade 6. During pruning, the user can control the second motor 13 to make its output end drive the gear 14 to rotate. At this time, the gear 14 will drive the fixed shaft 10 and the rotating block 1 to rotate, so as to adjust the cutting angle of the saw blade 6, which facilitates subsequent pruning and increases the flexibility of the device in use.

[0033] Please see Figure 1 and Figure 5 As an implementation method for adjusting the height of the saw blade 6: a guide cylinder 16 is fixedly provided at the bottom of the housing 12, a guide rod 17 is slidably provided inside the guide cylinder 16, a connecting block 18 is fixedly provided at the bottom of the guide rod 17, threaded posts 19 are provided on the upper end face of the connecting block 18 and on both sides, a fixing block 20 is provided at the tail end of the guide cylinder 16 and on both sides, the threaded posts 19 are movably installed with the fixing blocks 20, and an adjusting nut 21 is provided on each threaded post 19, two sets of adjusting nuts 21 are provided and they contact the upper and lower sides of the fixing blocks 20, and a handle 25 is fixedly provided at the bottom of the connecting block 18.

[0034] Specifically, the user can rotate the adjusting nut 21 to move the guide rod 17 inside the guide cylinder 16 to adjust the installation height of the saw blade 6. After adjustment, rotate the adjusting nut 21 to make it abut against the upper and lower sides of the fixing block 20, thereby achieving the effect of fixing the saw blade 6 for convenient subsequent use.

[0035] Please refer to Figure 2 As a further embodiment for positioning and installing the mounting rod 5: the mounting rod 5 has a locking block 22 on its outer wall and on both sides, and the mounting sleeve 4 has a corresponding locking groove 23 on its inner wall, with the locking block 22 located inside the locking groove 23.

[0036] Specifically, the locking block 22 can position and install the mounting rod 5 to make it more stable after installation.

[0037] In summary, when using the overall equipment: the user can control the first motor 3 to drive the mounting sleeve 4 and mounting rod 5 to rotate, thereby rotating the saw blade 6. The saw blade 6 then contacts the pear tree branch to be pruned, achieving the pruning effect. During pruning, the user can control the second motor 13 to drive the gear 14 to rotate. The gear 14 then drives the fixed shaft 10 and rotating block 1 to rotate, adjusting the cutting angle of the saw blade 6. This facilitates subsequent pruning and increases the flexibility of the device. The pin 8 can be removed from the insertion hole 7 by disassembling the fastening nut 9, allowing for easy disassembly and replacement of the saw blade 6. When the height of the saw blade 6 needs adjustment, the guide rod 17 can be moved inside the guide cylinder 16 by rotating the adjusting nut 21, adjusting the installation height of the saw blade 6. After adjustment, rotating the adjusting nut 21 causes it to contact the upper and lower sides of the fixed block 20, thus fixing the saw blade 6 for convenient subsequent use.

[0038] The motors mentioned above are all controlled by controllers or drivers. Since the controllers and matching equipment are common devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
