Description

Technical Field

[0001] This utility model relates to the field of tree pruning, and in particular to a shaping and pruning device for tall trees. Background Technology

[0002] In the shaping and pruning of tall trees, handheld chainsaws are currently commonly used to cut branches at height. However, the sawing process generates a large amount of debris that is sprayed out and cannot be effectively controlled. This not only seriously obstructs the operator's vision, affecting the safety and accuracy of the operation, but also causes pollution when it falls on the road, making the cleanup work more complicated. In addition, when locating the target branch, it is often impossible to work directly due to the obstruction of dense leaves and vines, and it is necessary to clear them first. If the chainsaw is used directly to cut the path, it is easy for the chainsaw to jam due to the entanglement of flexible fibers. At the same time, there is a safety risk of the cut material being splashed as a high-speed projectile. Utility Model Content

[0003] In order to overcome the shortcomings of debris scattering and polluting the environment and affecting safety during the pruning of tall trees, and the easy jamming of chainsaws and safety risks during the pretreatment of vines, this utility model provides a shaping and pruning device for tall trees.

[0004] Technical solution: A pruning and shaping device for tall trees includes a hand handle, a dustproof shell, and a circular saw mounted on one end of the hand handle; it also includes a dustproof shell; two symmetrically arranged dustproof shells are rotatably connected to the end of the hand handle on which the circular saw is mounted, and the dustproof shells are fitted over the circular saw; a conical base is fixedly connected to the hand handle, the conical base is located below the dustproof shell, and the conical base is designed to be concave in the center; two driving components are mounted on the conical base, and the driving components are rotatably connected to the corresponding dustproof shells; an elliptical opening is provided on the inner side of the dustproof shell, and a sealing block is provided at the opening.

[0005] Preferably, it also includes an air pump and a jet nozzle; the air pump is fixed to one side of the outer surface of the dustproof housing; several jet nozzles are installed on the air pump, and the jet nozzles pass through the dustproof housing and are aimed at the cutting position of the circular saw.

[0006] Preferably, it also includes a blade; the outer edge of the dustproof housing is fitted with a blade for cutting delicate vines and branches.

[0007] Preferably, the two dustproof shells are combined to form a cone shape with a sharp head.

[0008] Preferably, the sealing block is made of a flexible material.

[0009] Preferably, it also includes hooks, a protective cover, latches, studs, a handle, and feet; two hooks are rotatably connected to the conical base; a protective cover is detachably connected to the conical base; two latches are fixed to the protective cover; a stud for connecting the hand handle is fixed to the protective cover; the hand handle is a two-section fixed long rod, each long rod has an external thread at one end and an internal thread at the other end, the internal thread can engage with the external thread end and the stud on the long rod; a handle is fixed to the protective cover; two feet for stable support are fixed to the protective cover.

[0015] Example 1: A shaping and pruning device for tall trees, such as... Figures 1-7 As shown, it includes a hand handle 1, a dustproof housing 101, and a circular saw 2; a circular saw 2 for sawing thick tree branches is installed at one end of the hand handle 1. It also includes a dustproof shell 101, a conical base 102, a drive unit 103, and a sealing block 104; the end of the handle 1 on which the circular saw 2 is mounted is rotatably connected to two symmetrically arranged dustproof shells 101, which are fitted over the circular saw 2; the handle 1 is bolted to the conical base 102, which is located below the dustproof shell 101 and is designed with a central concave shape, which is beneficial for the blade 107 to cut vines or branches so that liquid flows onto the operator's hands; two drive units 103 are mounted on the conical base 102, which are electric push rods, located below the dustproof shell 101, and are rotatably connected to the corresponding dustproof shell 101. The extension and retraction of the output end of the drive unit 103 can control the opening and closing of the two dustproof shells 101; the inner side of the dustproof shell 101 has an elliptical opening, and a sealing block 104 is provided at the opening.

[0016] It also includes an air pump 105 and a jet nozzle 106; the air pump 105 is fixedly connected to one side of the outer surface of the dustproof housing 101; a number of jet nozzles 106 are installed on the air pump 105, and the jet nozzles 106 pass through the dustproof housing 101 and are aligned with the sawing position of the circular saw 2.

[0017] It also includes a blade 107; the blade 107 is installed at the outer edge of the dustproof housing 101.

[0018] The two dustproof shells 101 combine to form a sharp cone shape at the head, which makes it easier for the device to be inserted into the tangled vines.

[0019] The sealing block 104 is made of a flexible material that can conform to branches of different sizes and shapes to reduce debris flying out of the gaps.

[0020] It also includes hooks 108, protective covers 109, latches 110, studs 111, handles 112, and feet 113; two hooks 108 are rotatably connected to the conical base 102; the protective cover 109 is detachably connected to the conical base 102; two latches 110 are fixedly connected to the protective cover 109, and the latches 110 respectively cooperate with the corresponding hooks 108, so that the conical base 102 and the protective cover 109 can be easily disassembled; studs 111 are fixedly connected to the protective cover 109; the hand handle 1 is a long rod with two bolted sections, each long rod has an external thread at one end and an internal thread at the other end, and the internal thread can be engaged with the external thread end on the long rod and the stud 111; the handle 112 is fixedly connected to the protective cover 109; two feet 113 are fixedly connected to the protective cover 109.

[0021] The protective cover 109 has a groove that fits into the dustproof housing 101 and the blade 107, which helps to fix the dustproof housing 101 and the blade 107 and prevent the blade 107 from being bumped or damaged.

[0022] In the shaping and pruning of tall trees, handheld chainsaws are currently commonly used to cut branches at height. However, the sawing process generates a large amount of debris that is sprayed out and cannot be effectively controlled. This not only seriously obstructs the operator's vision, affecting the safety and accuracy of the operation, but also causes pollution when it falls on the road, making the cleanup work more complicated. In addition, when locating the target branch, it is often impossible to work directly due to the obstruction of dense leaves and vines, and it is necessary to clear them first. If the chainsaw is used directly to cut the path, it is easy for the chainsaw to jam due to the entanglement of flexible fibers. At the same time, there is a safety risk of the cut material being splashed as a high-speed projectile.

[0023] To address the aforementioned issues, this invention allows the operator to hold the handle 1 and extend one end of the circular saw 2 to the tree crown. The output end of the drive unit 103 then extends and retracts, driving the dustproof housing 101 to open and close. This allows the blade 107 to cut or separate intricately tangled vines, facilitating better positioning of the tree branch to be sawed. During this process, dew or sap on the vines drips or flows into the central recess of the conical base 102, preventing slippage on the operator's hand. When the saw reaches the tree branch, the drive unit 103 opens the dustproof housing 101, positioning the branch at the elliptical opening. The drive unit 103 then closes the dustproof housing 101, causing the sealing block 104 to deform under pressure from the branch and adhere to it. The process is then initiated. The circular saw 2 rotates to cut the branch. During the sawing process, it needs to be gradually pushed towards the branch to allow the circular saw 2 to complete the sawing. During the feeding process, the sealing block 104 also changes its deformation state with the movement of the branch. The debris generated during the sawing process is controlled inside the dustproof shell 101, which helps to reduce the problem of debris flying and polluting the environment and affecting the vision. At the same time, the air pump 105 is started to blow air through the air nozzle 106 to blow away the debris at the sawing point, preventing the debris from getting stuck in the circular saw 2. Blowing air on the circular saw 2 also helps to cool down and dissipate heat, which helps to improve the service life of the circular saw 2. When the branch is cut, the short branch falls directly. Then the rotation of the circular saw 2 and the air pump 105 are stopped. After that, the device can be directly retracted, and the dustproof shell 101 can be opened to collect and empty the debris inside.

[0024] After completing the entire operation, the dustproof housing 101 can be closed, and then the protective cover 109 can be placed on the dustproof housing 101. Simultaneously, the blade 107 on the dustproof housing 101 engages with the groove inside the protective cover 109, thus making the dustproof housing 101 more stable and preventing the blade 107 from being exposed and causing injury or damage when the device is idle. This improves the safety and lifespan of the device. Then, the handheld rod 1, consisting of two long sections, is removed and bolted to the stud 111 on the protective cover 109. Figure 6 As shown, this effectively reduces the space occupied by the device when it is not in use, making it easy to store.
