[0002] Brush cutters are indispensable equipment in forestry operations, playing a vital role in clearing shrubs and weeds, as well as in tree planting and forest management. However, traditional brush cutters often have limited functionality, low efficiency, and numerous safety hazards. For example, when the cutting blade strikes hard objects such as rocks, it can not only damage the blade but also send rocks flying, causing injury to the operator. Furthermore, traditional brush cutters often fail to effectively handle obstacles such as tree roots and rocks in the soil when clearing the ground, compromising the overall quality of the operation.

[0003] Based on this, the utility model proposes a multifunctional brush cutter for forestry operations to solve the above technical problems. Utility Model Content

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, a multifunctional brush cutter for forestry operations includes a frame 1, a mounting frame 2 is installed on the top of the frame 1, and hand-held rods 3 are fixedly installed on the left and right ends of the mounting frame 2, and rollers 4 are fixedly installed on the left and right ends of the bottom of the frame 1. A cutting blade 7 and two cutting ropes 8 are rotatably installed on the mounting frame 2, and a second rotating shaft 9 is rotatably installed on the frame 1, and a plurality of obstacle removal blades 10 are evenly installed on the second rotating shaft 9. The frame 1 serves as the supporting structure of the entire brush cutter and carries all working parts. The mounting frame 2 is installed on the top of the frame 1 and is used to install key components such as the cutting blade 7 and the cutting rope 8. The hand-held rod 3 is fixed on the left and right ends of the mounting frame 2, which is convenient for the operator to hold with both hands and control the balance and direction of the brush cutter. The roller 4 is installed at the bottom of the frame 1, so that the brush cutter can move flexibly on the ground, so that the operator can easily control the movement and working direction of the brush cutter. The cutting blade 7 can efficiently cut shrubs, weeds and other plants. The cutting rope 8 is another cutting method, which is cut by high speed. The rotation generates a cutting force, which facilitates the subsequent operation of the cutting blade 7. The weeds that are more dense on the ground can be cleared in advance, so that the stones on the ground are exposed, preventing the cutting blade 7 from hitting the stones and causing damage to the cutting blade 7. At the same time, it prevents the cutting blade 7 from knocking the stones away and causing harm to the operator, thereby improving the safety of the operation. The obstacle removal blade 10 installed on the second rotating shaft 9 can perform a secondary treatment on the ground after the brush cutter performs the initial cleaning treatment, effectively clearing obstacles such as tree roots and stones in the soil, ensuring the cleanliness and safety of the working area, and improving the overall quality of the operation.

[0023] The mounting frame 2 is rotatably mounted on the top of the frame 1; a first motor 5 is fixedly mounted on the mounting frame 2, and a first rotating shaft 6 is rotatably mounted on the mounting frame 2. The output end of the first motor 5 passes through the mounting frame 2 and is fixedly connected to the first rotating shaft 6. The cutting blade 7 is fixedly mounted on the upper end of the first rotating shaft 6, and two cutting ropes 8 are evenly mounted on the lower end of the first rotating shaft 6; the lengths of the two cutting ropes 8 are both greater than the radius of the cutting blade 7. The mounting frame 2 is connected to the top of the frame 1 by a rotatable mounting method. This design allows the mounting frame 2 to rotate within a certain range, thereby driving the cutting blade 7 and the cutting rope 8 to perform cutting operations at different angles; the first motor 5 is fixedly mounted on the mounting frame 2, and its output end passes through the mounting frame 2 and is fixedly connected to the first rotating shaft 6. When the first motor 5 is started, it drives the first rotating shaft 6 to rotate. The cutting blade 7 is fixedly mounted on the upper end of the first rotating shaft 6. As the first rotating shaft 6 rotates, the cutting blade 7 also rotates at high speed, which is used to cut shrubs, weeds and other plants. The two cutting ropes 8 are evenly mounted. Installed at the lower end of the first rotating shaft 6, they will rotate at high speed with the rotation of the first rotating shaft 6, generating a strong cutting force for clearing the weeds on the ground; the lengths of the two cutting ropes 8 are both greater than the radius of the cutting blade 7. This design ensures that during the cutting process, the cutting ropes 8 can first contact the weeds on the ground and clear them away, exposing the stones on the ground. Then, by rotating the mounting frame 2, the cutting blades 7 can avoid hard objects such as stones, thereby reducing the risk of the cutting blades 7 hitting hard objects such as stones, reducing the possibility of blade damage, and improving work safety.

[0024] Two second motors 11 are fixedly mounted on the frame 1. Both second motors 11 are located above the second rotating shaft 9. A transmission assembly 12 is installed between the two second motors 11 and the second rotating shaft 9. The two transmission assemblies 12 each include a first pulley 13, a second pulley 14, and a belt 15. A belt 15 is slidably mounted between the first pulley 13 and the second pulley 14. The two first pulleys 13 are fixedly mounted on the output ends of the two second motors 11, and the two second pulleys 14 are fixedly mounted on the left and right ends of the second rotating shaft 9. When the second motors 11 are started, the first pulleys 13 rotate accordingly. The belt 15 slides between the first pulley 13 and the second pulley 14. When the first pulley 13 rotates, the belt 15 transmits power to the second pulley 14, thereby driving the second rotating shaft 9 to rotate. The second rotating shaft 9 drives the obstacle removal blade 10 to rotate. The obstacle removal blade 10 can remove tree roots and stones from the ground after the initial treatment, performing a secondary treatment on the ground, ensuring the cleanliness and safety of the work area and improving the overall quality of the work.

[0025] A control panel 16 is fixedly mounted on the mounting frame 2. The first motor 5 and the two second motors 11 are electrically connected to the control panel 16. Through the control panel 16, the operator can intuitively understand the operating status of the brush cutter and control the brush cutter through simple operations. The operator can easily start, stop, and adjust the speed of the brush cutter without directly contacting the motors or other mechanical components, greatly improving the convenience and safety of operation.
