Abstract
Description
Technical Field
[0001] This utility model relates to the field of tree pruning technology, and in particular to a forestry tree pruning device. Background Technology
[0002] Forestry tree pruning equipment is a maintenance tool for human greening landscapes. It is used to maintain lawns, hedges, and protect flowers, grasses, and trees. With the development of urban construction in China in recent years, urban greening has become a large industry. Tree seedlings used for greening need to be pruned before planting.
[0003] Currently, existing forestry tree pruning equipment typically has basic cutting functions. While it can complete tree pruning operations, it cannot effectively handle falling branches during the cutting process. This leads to a high risk of workers being injured by falling branches, resulting in a high accident rate. This not only threatens the safety of personnel but may also damage the equipment, causing work stoppages and affecting the efficiency and safety of pruning work. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot effectively handle fallen branches during the cutting process, leading to injuries to workers and equipment damage. This invention provides a forestry tree pruning device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A forestry tree pruning device, comprising:
[0007] The main column has two U-shaped brackets fixedly installed on its top side, and the other end of the two U-shaped brackets is fixedly installed with the same secondary column. The bottom end of the main column is fixedly installed with a connecting column.
[0008] The main column is equipped with a sweeping assembly for sweeping away fallen branches, and the secondary column is equipped with a cutting assembly for pruning trees.
[0009] In one possible design, the sweeping assembly includes a single rotating rod rotatably mounted inside the main column and the auxiliary column via bearings. A connecting ring is fixedly mounted on the outside of the rotating rod at a U-shaped frame between the main column and the auxiliary column. Stop bars are symmetrically fixed on both sides of the connecting ring. A motor is fixedly mounted inside the connecting column, and the output shaft of the motor is fixedly connected to the bottom end of the rotating rod.
[0010] In one possible design, the cutting assembly includes a connecting box fixedly mounted on the top of the sub-column. A rotating shaft is rotatably mounted on one side of the connecting box. A cutting blade is fixedly mounted on the outer end of the rotating shaft by a nut. A driven bevel gear is fixedly mounted on the end of the rotating shaft located inside the connecting box. An active bevel gear is fixedly mounted on a rotating rod located inside the connecting box. The active bevel gear meshes with the driven bevel gear for transmission.
[0011] In one possible design, a hanging ring is fixedly provided on one side of both the main column and the connecting column. A hook can be detached from each of the two hanging rings. The same carrying strap is fixedly provided on each of the two hooks. A silicone pad is fixedly provided on the inner side of the carrying strap.
[0012] In one possible design, the main column is externally fixed with an anti-slip sleeve.
[0013] In one possible design, a connecting seat is fixedly provided at the bottom of the connecting column.
[0014] In this application, if it is found that the length of the equipment cannot meet the trimming requirements before use, the connecting seat at the bottom of the connecting column can be used to extend the length. The prepared extension part (which also has a hanging ring installed on it) is threaded to the connecting seat to ensure a tight connection and avoid loosening or falling off during use, which would affect the normal progress of the trimming work.
[0015] To begin use, attach the shoulder strap to the hook on the hanging ring on one side of the main column and connecting column. Adjust the length of the shoulder strap to ensure the device is comfortably worn. The silicone pad should conform to the body to reduce pressure and maintain relative comfort even during extended use. Then, grasp the controller provided with the device and press the controller switch to power the motor inside the connecting column. This will start the motor, causing the motor's output shaft to rotate. As the rotating shaft rotates, the active bevel gear fixedly mounted on the rotating shaft inside the connecting box will also rotate. Because the active bevel gear and the fixed bevel gear are located inside the connecting box... The driven bevel gears at the end engage in a transmission, so the active bevel gears drive the driven bevel gears to rotate, which in turn causes the shaft to rotate. At the same time, the cutting blade at the outer end of the shaft rotates at high speed. At this time, the user holds the main column and brings the cutting blade close to the part of the tree that needs to be pruned, so that the tree can be pruned. As the rotating rod rotates, it causes the cutting blade to rotate, which in turn causes the connecting ring fixed at the U-shaped frame between the main column and the auxiliary column to rotate. The stop bars fixed on both sides of the connecting ring rotate accordingly. During the tree pruning process, when a branch falls, the stop bars will sweep the fallen branch away to prevent it from hitting the staff and ensure operational safety.
[0016] During use, the user must always hold the main column firmly, use the anti-slip sleeve to increase friction and prevent the equipment from slipping out of their hand, pay attention to the surrounding environment, and ensure that there are no other personnel or obstacles in the working range of the cutting blade to avoid accidents. At the same time, the pruning force and angle should be reasonably controlled, and the operation should be carried out according to the growth of the tree and the pruning needs to achieve the ideal pruning effect.
[0017] This utility model has the following beneficial effects:
[0018] This invention, through the design of the cutting components, allows users to more precisely control the cutting position and force, effectively improving the quality and efficiency of tree pruning and meeting the actual needs of forestry tree pruning work.
[0019] By incorporating a sweeping component, this invention effectively prevents tree branches from hitting workers during the cutting process, allowing them to operate in a safe environment. This not only significantly reduces the accident rate and protects personnel safety but also prevents equipment damage and work stoppages caused by accidents, ensuring the efficient, stable, and reliable progress of forestry tree pruning.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In one embodiment
[0027] Reference Figure 1-4 A pruning device, comprising:
[0028] The main column 1, the secondary column 3, the connecting column 8 (which has a power supply inside, such as a "battery", and a control switch on the outside, which is electrically connected to the motor 9 through a spring-type power cable), as well as sweeping assembly, cutting assembly, carrying assembly, etc. The main column 1 is the main support structure of the equipment. Two U-shaped frames 2 are fixedly installed on its top side. The other ends of these two U-shaped frames 2 are fixedly connected to the secondary column 3. The bottom end of the main column 1 is fixedly connected to the connecting column 8.
[0029] The cutting assembly is installed on the secondary column 3 for pruning trees. A connecting box 4 is fixedly installed at the top of the secondary column 3. A rotating shaft 10 is rotatably installed on one side of the connecting box 4. A cutting blade 11 is fixedly installed on the outer end of the rotating shaft 10 by locking it with a nut. A driven bevel gear 12 is fixedly installed at one end of the rotating shaft 10 inside the connecting box 4, while an active bevel gear 13 is fixedly installed on the rotating rod 5 inside the connecting box 4. The active bevel gear 13 meshes with the driven bevel gear 12 for transmission. When the rotating rod 5 rotates, the active bevel gear 13 drives the driven bevel gear 12 to rotate, thereby causing the rotating shaft 10 and the cutting blade 11 to rotate at high speed, realizing the cutting and pruning of trees.
[0030] The sweeping assembly is installed on the main column 1. Its function is to sweep away fallen branches to prevent them from hitting workers. It includes a rotating rod 5 that is rotatably installed inside the main column 1 and the secondary column 3 via bearings. A connecting ring 6 is fixedly installed on the outside of the rotating rod 5 at the position of the U-shaped frame 2 between the main column 1 and the secondary column 3. A stop bar 7 is fixedly installed on both sides of the connecting ring 6. A motor 9 is fixedly installed inside the connecting column 8. The output shaft of the motor 9 is fixedly connected to the bottom end of the rotating rod 5. When the motor 9 starts, its output shaft drives the rotating rod 5 to rotate, which in turn causes the connecting ring 6 and the stop bar 7 to rotate. If a branch falls during tree pruning, the stop bar 7 can sweep it away.
[0031] To make it easier for users to use the equipment, a hanging ring 16 is fixedly installed on one side of both the main column 1 and the connecting column 8. A hook 17 can be detachably hung on both hanging rings 16. The same carrying strap 18 is fixedly connected to both hooks 17. A silicone pad 19 is fixedly installed on the inside of the carrying strap 18. The silicone pad 19 can increase the comfort when carrying the equipment. Users can hang the carrying strap 18 on the hanging ring 16 through the hook 17, adjust the length of the carrying strap 18, and then carry the equipment on their body to operate it.
