Description
Technical Field
[0001] This utility model relates to the field of brush cutter technology, specifically a high-efficiency directional handheld brush cutter. Background Technology
[0002] A handheld brush cutter is a portable gardening machine used for cutting shrubs, weeds, and other vegetation. It is compact, lightweight, and easy to operate, mainly consisting of an engine, transmission, blades, and a handle. Its working principle is that the engine provides power, which drives the blades to rotate at high speed via the transmission, cutting and shredding the vegetation with the sharp blades. Depending on the work scenario, various blade types are available, such as manganese steel blades suitable for cutting harder shrubs, and nylon weeding ropes more suitable for trimming softer weeds. Handheld brush cutters play an important role in garden maintenance, orchard management, and wasteland reclamation. However, existing handheld brush cutters have some shortcomings.
[0003] For example, a high-efficiency, directional handheld brush cutter with application number CN202222441583.4 relates to the field of brush cutters. It addresses the problem of difficulty in gathering the cut grass clippings after mowing, where large areas of grass clippings are scattered after mowing, requiring manual collection by workers, resulting in low efficiency and labor consumption. The brush cutter body has a clamping ring movably connected to its outer surface. The bottom of the clamping ring is hinged to an adjusting plate. Rotary grooves are fixedly connected to both sides of the adjusting plate. A rotating rod is rotatably connected to the inner wall of the rotating groove. A movable frame is fixedly connected to one end of the rotating rod. Rollers are provided on both sides of the movable frame. A cylinder is fixedly connected to one side of the movable frame. A telescopic rod is fixedly connected to the output end of the cylinder. A connecting frame is fixedly connected to the bottom end of the telescopic rod. A grass-pushing plate is fixedly connected to one side of the connecting frame. A gathering rod is fixedly connected to one side of the grass-pushing plate. However, this brush cutter experiences significant vibration, is prone to fatigue after prolonged use, has limited functionality, and exhibits poor stability during operation.
[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a high-efficiency directional handheld brush cutter. Utility Model Content
[0005] The purpose of this invention is to provide a high-efficiency, directional handheld brush cutter to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency reversible handheld brush cutter, comprising an engine and a handheld shock-absorbing mechanism, characterized in that the handheld shock-absorbing mechanism is fixedly connected to one side of the engine, and the handheld shock-absorbing mechanism includes a fixed block fixedly connected to one side of the engine, a shock-absorbing rod fixedly connected to one side of the fixed block, and a connecting plate fixedly connected to one end of the shock-absorbing rod, an adjusting rod provided on one side of the connecting plate, and an adjustment handle fixedly connected to one end of the adjusting rod.
[0007] Preferably, a drive shaft is fixedly connected to one side of the engine, and a connecting wire is electrically connected to one side of the engine.
[0008] Preferably, a fixed shaft is fixedly connected to the outer surface of the drive shaft, and a rotating shaft is fixedly connected to the fixed shaft.
[0009] Preferably, the rotating shaft is provided with a support rod, and the bottom of the support rod is fixedly connected to a base plate.
[0010] Preferably, a water supply mechanism is fixedly connected to the top of the base plate.
[0011] Preferably, the water supply mechanism includes a water storage tank fixedly connected to the top of the base plate, a delivery pipe fixedly connected to one side of the water storage tank, a nozzle fixedly connected to one side of the delivery pipe, and a shock-absorbing pad fixedly connected to the bottom of the water storage tank.
[0012] Preferably, a cutting component is provided on one side of the drive shaft, and a protective frame is provided on one side of the cutting component, and a caster wheel is provided at the bottom of the shock-absorbing pad.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the setting of a handheld shock-absorbing mechanism, when vibration is transmitted, the damping medium inside the shock-absorbing rod first converts the high-frequency vibration energy into heat energy through intermolecular friction, and the elastic steel sheet buffers the remaining impact force by its own deformation, weakening most of the vibration. Finally, the vibration transmitted to the adjustment handle is greatly attenuated, so that even if the operator works continuously for several hours, his / her hands will not become numb or stiff due to excessive vibration, effectively reducing fatigue, ensuring the continuity and accuracy of the operation, and ensuring that the brush cutter can perform at its best in the hands of operators of different body sizes, greatly improving the versatility and work efficiency of the equipment;
[0015] 2. This utility model, through the setting of the water source delivery mechanism, can complete brush cutting and irrigation operations simultaneously without frequent equipment replacement, thereby improving work efficiency and reducing equipment procurement and maintenance costs. It significantly enhances the equipment's adaptability and cost-effectiveness. After brush cutting causes wounds on plants, the water source delivery mechanism sprays water evenly onto the vegetation surface and roots through atomizing nozzles. This avoids soil compaction caused by over-irrigation and can replenish water to damaged plants in a timely manner, accelerating wound healing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-2As shown, a high-efficiency reversible handheld brush cutter includes an engine 1 and a handheld shock-absorbing mechanism 2. The handheld shock-absorbing mechanism 2 is fixedly connected to one side of the engine 1. The handheld shock-absorbing mechanism 2 includes a fixed block 201 fixedly connected to one side of the engine 1. A shock-absorbing rod 202 is fixedly connected to one side of the fixed block 201, and a connecting plate 203 is fixedly connected to one end of the shock-absorbing rod 202. An adjusting rod 204 is provided on one side of the connecting plate 203, and an adjustment handle 205 is fixedly connected to one end of the adjusting rod 204. The engine 1 is the power source of the brush cutter. Two sets of symmetrical shock-absorbing rods 202 are located between the fixed block 201 and the connecting plate 203. The vibration generated by the engine 1 is weakened by the shock-absorbing rods 202 and then transmitted to the adjustment handle 205, reducing hand vibration and easing the operator's burden. The adjusting rod 204 can change the distance between the two sets of adjustment handles 205, making it convenient for operators of different body types to use.
[0023] like Figure 1 As shown, a drive shaft 3 is fixedly connected to one side of the engine 1, and a connecting wire 4 is electrically connected to one side of the engine 1. A fixed shaft 5 is fixedly connected to the outer surface of the drive shaft 3, and a rotating shaft 6 is fixedly connected to the fixed shaft 5. A drive wire is installed inside the drive shaft 3, and the drive wire connects the engine 1 to the cutting assembly 10. Loosening the fastening bolt of the rotating shaft 6 can change the angle of the base plate 8 and the top assembly of the base plate 8, adapting to different environments for mowing work.
[0024] Furthermore, a support rod 7 is provided on the rotating shaft 6, and a base plate 8 is fixedly connected to the bottom of the support rod 7. A water supply mechanism 9 is fixedly connected to the top of the base plate 8. The support rod 7, the fixed shaft 5, and the base plate 8 form a triangular support mechanism, which makes the handheld brush cutter more stable during operation.
[0025] Furthermore, the water delivery mechanism 9 includes a water storage tank 901 fixedly connected to the top of the base plate 8, and a delivery pipe 902 fixedly connected to one side of the water storage tank 901. A nozzle 903 is fixedly connected to one side of the delivery pipe 902, and a shock-absorbing pad 904 is fixedly connected to the bottom of the water storage tank 901. The interior of the water storage tank 901 can store water and nutrient solution needed by the vegetation. When needed, the pressure pump inside the water storage tank 901 will deliver the liquid through the nozzle 903 on one side of the delivery pipe 902 to irrigate the vegetation evenly.
[0026] Furthermore, a cutting assembly 10 is provided on one side of the drive shaft 3, and a protective frame 11 is provided on one side of the cutting assembly 10. A caster wheel 12 is provided at the bottom of the shock-absorbing pad 904. The cutting blade of the cutting assembly 10 can be quickly replaced to avoid affecting the cutting efficiency due to damage to the cutting blade. The protective frame 11 prevents the cutting blade from causing injury to the operator and prevents the cutting vegetation debris from flying.
[0027] Working Principle: When using this high-efficiency reversible handheld brush cutter, the operator first adjusts the adjustment rod 204 of the handheld shock-absorbing mechanism 2 to a suitable length according to their needs. After holding the adjustment handle 205, the operator starts the engine 1. The engine 1 drives the cutting component 10 at one end of the drive shaft 3 to start working. During the operation, the vibration generated by the engine 1 is weakened by the shock-absorbing rod 202 on one side of the fixed block 201 and then transmitted to the adjustment handle 205 on the side of the connecting plate 203, reducing the impact on the hand due to vibration. Then, during the operation of the brush cutter, the support rod 7 at the bottom of the fixed shaft 5, the base plate 8, and the drive shaft 3 form a triangular support mechanism. When the caster wheel 12 is running, the brush cutter is more stable. At the same time, after the cutting component 10 creates wounds on the vegetation, the nutrient solution inside the water tank 901 of the water supply mechanism 9 irrigates the vegetation through the nozzle 903 at one end of the delivery pipe 902, accelerating wound healing. Finally, during the operation of the cutting component 10, the protective frame 11 prevents grass clippings from flying. This is the working principle of this high-efficiency reversible handheld brush cutter.
