[0002] In garden pruning and forestry tending, pruning machines are key tools for ensuring healthy plant growth and optimizing forest structure. Their performance directly affects operational efficiency, cost control, and safety. However, existing pruning machine technology still has many limitations, making it difficult to meet the demands for efficient, safe, and convenient operations. For example: 1. Single-blade pruning machines require repeated application of force when cutting, making it difficult to cut thick branches in one go, and the operation is laborious; 2. Although some electric pruning machines are highly efficient, their blades are prone to wear due to excessive impact, and the blades may rebound after cutting, posing a safety hazard during operation.

[0003] Based on the above, this utility model proposes a double-blade impact pruning machine, which can effectively solve the above problems. Utility Model Content

[0017] 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.

[0018] Example: like Figure 1-5 As shown, this utility model embodiment provides a double-blade impact pruning machine, including a machine head 1, one end of which is detachably connected to a handle 11, and a fixed shear head 12 is fixedly connected to the inner side wall of the machine head 11. Power source 2 is located inside handle 11; The impact mechanism 3 is installed inside the machine head 1 and is connected to the power source 2 via transmission. The movable shear head 4 is rotatably connected inside the machine head 1. Both the movable shear head 4 and the fixed shear head 12 have detachable blades 13 on opposite sides. The impact mechanism 3 is used to apply an impact force to the moving shear head 4 during pruning, so that the two blades 13 close quickly to cut the branch; The locking mechanism 5 is located inside the machine head 1 and is used to restrict the reverse rotation of the movable shear head 4 when the movable shear head 4 cuts the branch.

[0019] Because the double-blade impact pruning machine of this utility model has the above structure, the double-blade design combined with the impact shearing structure provides a strong impact force through the hydraulic push rod 3, which makes the blade 13 close quickly, suitable for the rapid cutting of thick branches; the locking mechanism 5 restricts the reverse rotation of the moving shear head 4 through the pawl 52 and the ratchet 51, effectively preventing the blade 13 from rebounding and avoiding injury to the operator; the blade 13 is detachably connected by the slot and bolt, and can be quickly replaced after wear, without the need to disassemble the whole equipment, resulting in low maintenance costs.

[0020] Furthermore, in another embodiment, the power source 2 is a hydraulic cylinder, and the power source 2 is connected to the impact mechanism 3 through an oil pipeline.

[0021] Both the moving cutter head 4 and the fixed cutter head 12 have slots on their inner sidewalls. After the blade 13 is engaged in the slots, it is fixedly connected to the moving cutter head 4 and the fixed cutter head 12 respectively by bolts.

[0022] Because the double-blade impact pruning machine of this utility model has the above structure, when the hydraulic cylinder (power source 2) is activated, hydraulic oil enters the impact mechanism 3 through the oil supply pipeline, converting hydraulic energy into mechanical impact force. The hydraulic power source 2 provides stable and powerful power output, ensuring sufficient impact force during pruning, and is suitable for pruning thick branches. Compared with the electric power source, the hydraulic system is more impact-resistant and has a more stable power output. The blade 13 is detachably connected through slots and bolts. When the blade 13 is worn due to pruning, it can be quickly removed and replaced without replacing the entire moving pruning head 4 or the fixed pruning head 12, reducing maintenance costs and increasing the service life of the equipment.

[0023] Furthermore, in another embodiment, the impact mechanism 3 is a hydraulic push rod, which includes a hydraulic sleeve 31, a piston slidably inserted into the inner wall of the hydraulic sleeve 31, and a hydraulic rod 32 fixedly connected to the side wall of the piston. The tail end of the hydraulic sleeve 31 is rotatably connected to the fixed axis of the inner wall of the machine head 1, and the front end of the hydraulic rod 32 is rotatably connected to the moving shear head 4.

[0024] Because the double-blade impact pruning machine of this utility model has the above structure, the hydraulic oil output by the hydraulic cylinder (power source 2) pushes the piston to slide in the hydraulic sleeve 31, driving the hydraulic rod 32 to apply an impact force to the moving pruning head 4, causing the moving pruning head 4 to rotate around the support shaft 41, driving the blade 13 to close quickly. The hydraulic push rod 3 converts hydraulic energy into precise impact force, realizing the rapid and powerful closing of the blade 13, with high pruning efficiency and controllable impact force, avoiding damage to the blade 13 due to excessive impact.

[0025] Furthermore, in another embodiment, a support shaft 41 is fixedly connected to the middle of the movable shear head 4, and the two ends of the support shaft 41 are rotatably connected to the machine head 1 through bearings.

[0026] The side wall of the fixed shear head 12 has a through hole, and the fixed shear head 12 is inserted into the support shaft 41 and then fixedly connected to the machine head 1.

[0027] Because the double-blade impact pruning machine of this utility model has the above structure, the support shaft 41 is rotatably connected to the machine head 1 through the bearing, providing a stable rotation fulcrum for the moving pruning head 4, ensuring that the moving pruning head 4 rotates smoothly under the impact force, and avoiding pruning failure or equipment damage due to rotation jamming; the fixed pruning head 12 is inserted into the support shaft 41 through the through hole to achieve a fixed connection with the machine head 1, and at the same time provides a reference for the rotation of the moving pruning head 4, ensuring that the relative position of the moving pruning head 4 and the fixed pruning head 12 is stable, and the blade 13 has high alignment accuracy when closed, resulting in good pruning effect.

[0028] Furthermore, in another embodiment, the locking mechanism 5 includes a ratchet 51 fixedly connected to the side wall of the support shaft 41, and a pawl 52 rotatably connected to the side wall of the head 1, the pawl 52 being elastically engaged with the head 1 via a torque shaft.

[0029] The locking mechanism 5 also includes an unlocking mechanism provided on the machine head 1. The unlocking mechanism includes a slide 53 connected to the machine head 1 and a push rod 54 slidably connected to the inner wall of the slide 53. The push rod 54 and the slide 53 are elastically engaged by a tension spring 55. An electromagnet 56 is also provided on the inner bottom wall of the slide 53. When the electromagnet 56 is energized, it pushes the push rod 54 to slide out and abut against the pawl 52, causing the pawl 52 to rotate and release the restriction on the ratchet 51.

[0030] Because the double-blade impact pruning machine of this utility model has the above structure, when the moving pruning head 4 rotates under the impact force and cuts the branch, the ratchet 51 rotates with the support shaft 41, and the pawl 52 is locked by the elastic action of the torque shaft, restricting the moving pruning head 4 from rotating in the opposite direction, preventing the blade 13 from rebounding after cutting, ensuring operational safety, and ensuring the completion of the cutting action; after the cutting is completed, the electromagnet 56 is energized, generating magnetic force to push the push rod 54 to overcome the elastic force of the tension spring 55 and slide out, abutting the pawl 52 to make it rotate around the torque shaft, releasing the restriction on the ratchet 51, and the moving pruning head 4 can be reset to the initial position to prepare for the next cutting. The unlocking mechanism controlled by the electromagnet 56 is easy to operate and responds quickly, ensuring the continuity of the pruning process.
