Description

Technical Field

[0001] This utility model belongs to the technical field of transplanting equipment, specifically a buffer device for reducing vibration during transplanting by the cylinder of a cutting brush machine. Background Technology

[0002] As a key piece of equipment in machining, material processing and other fields, the brush cutter's cylinder transfer device undertakes core operations such as workpiece transfer and component positioning. The stability of the transfer process directly affects the processing accuracy, workpiece quality and equipment lifespan of the brush cutter.

[0003] Traditional brush cutter cylinder transfer mechanisms typically employ fixed buffer structures, using a single spring or rubber pad for passive buffering. The spring preload cannot be flexibly adjusted according to vibration intensity under different operating conditions such as transfer load and working frequency, resulting in poor buffering adaptability. When vibration intensity is low, excessive preload can cause rigid impact to the mechanism; when vibration intensity is high, insufficient buffering capacity cannot effectively absorb vibration energy, and machine vibration will still occur. Therefore, this application proposes a buffer device to reduce vibration during brush cutter cylinder transfer. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a buffer device for reducing vibration during the transfer of the cylinder of the brush cutter, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a buffer device for reducing vibration during cylinder transplantation of a brush cutter, comprising a base plate, wherein a transplanting machine body is provided at the upper end of the base plate, and buffer mechanisms are provided on both sides of the transplanting machine body; The buffer mechanism includes symmetrically fixed support columns at the upper end of the base plate, a mounting plate fixed at the upper end of the support columns, and side plates symmetrically fixed at the upper end of the mounting plates. Each side plate has a mounting groove on one side, and a connecting rod is symmetrically slidably arranged at the upper end of each mounting groove. A horizontal plate is fixed at the upper end of the connecting rod, and springs are symmetrically fixed at the lower end of the horizontal plate. The lower ends of both springs are fixedly connected to the upper end of the mounting plate.

[0006] The side wall of the mounting groove is provided with a bidirectional lead screw. One side of the bidirectional lead screw is rotatably connected to the inner wall of the mounting groove, and the other end of the bidirectional lead screw extends to the outside of the side plate and is fixed with a rotating ring. The outside of the bidirectional lead screw is symmetrically provided with moving blocks. The moving blocks are threadedly connected to the bidirectional lead screw. The upper ends of the two moving blocks and the lower ends of the two connecting rods are fixed with connecting seats. The two connecting seats are rotatably connected by a fixed rod.

[0007] Both sides of the transplanter are fixed with locking blocks, and the upper ends of the two horizontal plates are fixed with electric push rods. The output ends of the two electric push rods are fixed with locking blocks, and the locking blocks are movably connected to the locking blocks.

[0008] A locking block is provided on the outside of the bidirectional lead screw, and the locking block is threadedly connected to the bidirectional lead screw.

[0009] A hydraulic cylinder is fixed at the upper middle part of the base plate, and a support plate is fixed at the output end of the hydraulic cylinder. The transplanting machine body is placed on the upper end of the support plate.

[0010] The upper end of the support plate is provided with multiple layers of soft rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the setting of the buffer mechanism, the mechanism drives the locking block to extend and retract through the output end of the electric push rod, so that the locking block and the locking blocks on both sides of the transplanter body form a locking connection, restricting the lateral displacement of the transplanter body. According to the vibration intensity requirements of the transplanter body during operation, the rotating ring is rotated, and the rotating ring drives the bidirectional screw to rotate. When the bidirectional screw rotates, it drives the two moving blocks to move closer or further away, thereby pushing the connecting rod to slide along the mounting groove on the side plate. The connecting rod drives the horizontal plate to rise and fall, changing the compression or tension state of the spring, and realizing the adjustment of the spring preload. After the adjustment is completed, the locking block outside the bidirectional screw is tightened to ensure the stability of the spring preload. When the transplanter body vibrates during operation, the buffer mechanism on both sides directly buffers the vibration source, and the spring absorbs the vibration energy through its own elastic deformation. 2. The output end of the hydraulic cylinder drives the support plate to rise and fall. The position of the support plate is adjusted according to the specifications and height of the transplanter body so that the support plate supports the bottom of the transplanter body and distributes the weight of the transplanter body. At the same time, the multi-layer soft rubber on the upper part of the support plate increases the friction between the transplanter body and the support plate, completing the initial support and adaptation of the transplanter body.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figures 1 to 4 As shown, this utility model includes a base plate 1, a transplanter body 2 is provided at the upper end of the base plate 1, and a buffer mechanism 3 is provided on both sides of the transplanter body 2. The buffer mechanism 3 includes a support column 31 symmetrically fixed to the upper end of the base plate 1, a mounting plate 32 fixed to the upper end of the support column 31, a side plate 33 symmetrically fixed to the upper end of the mounting plate 32, a mounting groove 34 opened on one side of each of the two side plates 33, a connecting rod 35 symmetrically slidably arranged at the upper end of each of the two mounting grooves 34, a horizontal plate 36 fixed to the upper end of the connecting rod 35, and springs 37 symmetrically fixed to the lower end of the horizontal plate 36. The lower ends of the two springs 37 are fixedly connected to the upper end of the mounting plate 32. The side wall of the mounting groove 34 is provided with a bidirectional screw 38. One side of the bidirectional screw 38 is rotatably connected to the inner wall of the mounting groove 34. The other end of the bidirectional screw 38 extends to the outside of the side plate 33 and is fixed with a rotating ring 315. The outside of the bidirectional screw 38 is symmetrically provided with moving blocks 39. The moving blocks 39 are threadedly connected to the bidirectional screw 38. The upper ends of the two moving blocks 39 and the lower ends of the two connecting rods 35 are fixed with connecting seats 310. The two connecting seats 310 are rotatably connected through a fixing rod 311. The transplanter body 2 is installed on the upper end of the base plate 1. The buffer mechanisms 3 on both sides of the body directly correspond to the vibration source of the transplanter body 2. The vibration generated during the transplanting process will be directly received and buffered by the buffer mechanisms 3 on both sides. The rotating ring 315 drives the bidirectional screw 38 to rotate, causing the externally threaded moving block 39 to move relative to the body. The connecting rod 35 is pushed to slide along the mounting groove 34 through the connecting seat 310 and the fixed rod 311, thereby adjusting the height of the horizontal plate 36 and changing the compression or tension state of the spring 37. When the transplanting is vibrating, the spring 37 absorbs the vibration energy through elastic deformation to achieve buffering. The preload of the spring 37 can be adjusted by the bidirectional screw 38 to adapt to different intensity vibration scenarios. Both sides of the transplanter body 2 are fixed with locking blocks 312, and the upper ends of the two horizontal plates 36 are fixed with electric push rods 313. The output ends of the two electric push rods 313 are fixed with locking blocks 314, and the locking blocks 314 are movably connected to the locking blocks 312. When the electric push rod 313 is activated, its output end drives the locking block 314 to extend and retract, forming a locking connection with the locking blocks 312 on both sides of the transplanter body 2, thus fixing the position of the transplanter body 2. When vibration occurs, the locking structure restricts the lateral displacement of the transplanter body 2, and in conjunction with the elastic buffering of the buffering mechanism 3, prevents the transplanter body 2 from shifting during vibration, thereby improving the efficiency of the buffering mechanism 3. The locking structure is controlled by the electric push rod 313, making it easy to operate and allowing for quick fixing and disassembly of the transplanter body 2, balancing buffering effect with usage flexibility. A locking block 316 is provided on the outside of the double-acting lead screw 38, and the locking block 316 is threadedly connected to the double-acting lead screw 38; After the bidirectional lead screw 38 is adjusted, tighten the locking block 316 on its outside to fix the position of the moving block 39 with the thread locking force, so as to prevent the moving block 39 from shifting due to vibration during the buffering process and ensure the stability of the preload state of the spring 37. A hydraulic cylinder 4 is fixed at the upper middle part of the base plate 1, and a support plate 5 is fixed at the output end of the hydraulic cylinder 4. The transplanting machine body 2 is placed on the upper end of the support plate 5. The hydraulic cylinder 4 adjusts the height of the support plate 5 through the output end, so that the support plate 5 supports the bottom of the transplanter body 2. During the transplanting process, the support plate 5 distributes the weight of the transplanter body 2. Together with the buffer mechanism 3 on both sides, it can adapt to the installation requirements of different heights. The height adjustment function improves the adaptability of the device and can meet the use of transplanter bodies 2 of different specifications. The upper end of the support plate 5 is provided with multiple layers of soft rubber; The soft rubber increases the friction between the transplanter body 2 and the support plate 5, reducing bottom slippage during vibration; Working principle: During use, hydraulic cylinder 4 is activated, and its output drives the support plate 5 to rise and fall. The position of the support plate 5 is adjusted according to the height of the transplanter body 2, ensuring it supports the bottom of the transplanter body 2. Simultaneously, the multiple layers of soft rubber on the upper part of the support plate 5 increase the friction between the transplanter body 2 and the support plate 5, completing the initial support and fit of the transplanter body 2. Electric push rod 313 is activated, and its output drives the locking block 314 to extend and retract, causing the locking block 314 to engage with the locking blocks 312 on both sides of the transplanter body 2, restricting the lateral displacement of the transplanter body 2. Based on the vibration intensity requirements of the transplanter body 2 during operation, rotating ring 315 is rotated, driving the double-acting screw 38 to rotate. Since the moving block 39 is threadedly connected to the double-acting screw 38, the rotation of the double-acting screw 38 drives the two moving blocks 39 to move closer or further apart. The moving blocks 39 are connected to the connecting seat 310. The fixed rod 311 is rotated, which in turn pushes the connecting rod 35 to slide along the mounting groove 34 on the side plate 33; the connecting rod 35 drives the horizontal plate 36 to rise and fall, changing the compression or tension state of the spring 37, thereby adjusting the preload of the spring 37; after adjustment, the locking block 316 outside the double-acting screw 38 is tightened, and the position of the moving block 39 is fixed by the thread locking force to prevent the moving block 39 from shifting due to vibration during the buffering process, ensuring the stability of the preload of the spring 37; when the transplanter body 2 vibrates during operation, the buffering mechanisms 3 on both sides directly buffer the vibration source; the spring 37 absorbs vibration energy through its own elastic deformation, achieving the core buffering function; at the same time, the engaging structure of the locking block 314 and the locking block 312 continuously restricts the lateral displacement of the transplanter body 2, preventing the transplanter body 2 from shifting due to vibration, improving the efficiency of the buffering mechanism 3, adapting to different intensity vibration scenarios, and ensuring the stable operation of the transplanter body 2.
