Description

Technical Field

[0001] This utility model belongs to the field of wood chippers, specifically relating to a multi-wedge belt tension adjustment installation structure and a wood chipper. Background Technology

[0002] The wood chipper shreds wood, branches, leaves and other plant materials into small pieces, greatly reducing the workload of workers in gardens, orchards and sanitation facilities, and also enabling the secondary use of materials.

[0003] Most shredders on the market currently use a multi-wedge belt drive structure. However, during the installation of the transmission and output components, the fixed installation positions make it impossible to guarantee the tension of the multi-wedge belt, which can easily lead to slippage and ultimately affect the smoothness and stability of the cutting blades. Traditional tensioning methods using tensioning rollers increase structural complexity and cost, are inconvenient to assemble in the confined space of a shredder, are cumbersome to operate, and cannot guarantee long-term stability. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a multi-wedge belt tension adjustment and installation structure and a wood chipper that is simple in structure, easy to operate, and ensures long-term stable and reliable operation of the transmission system.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: proposing a multi-wedge belt tension adjustment and installation structure, comprising: a housing with an internal installation frame;

[0006] The system includes an output component and a transmission component. The output component is fixed to the side wall of the mounting frame and is connected to the transmission component via a multi-wedge belt drive to drive the cutting blade connected to the output component to rotate. The transmission component is movably located on the side of the mounting frame away from the output component, and adjusts the tension of the multi-wedge belt as the transmission component moves closer to or away from the output component along the length of the mounting frame.

[0007] The stop block and the locking member are provided. The stop block is movably engaged within the mounting frame and abuts against the side wall of the transmission member, so that the locking member locks the transmission member within the mounting frame.

[0008] In the above-mentioned multi-wedge belt tension adjustment installation structure, the transmission component includes:

[0009] The movable seat has a guide groove along its length provided on the mounting frame, and the movable seat is movably disposed within the guide groove.

[0010] The moving base has an air guide cavity, and the air guide wheel is rotatably disposed within the air guide cavity. The driving component is mounted on the outer wall of the moving base, and the drive shaft of the driving component is connected to the air guide wheel and extends to the outside of the mounting frame to adjust the tension of the multi-wedge belt.

[0011] In the above-mentioned multi-wedge belt tension adjustment installation structure, a micro switch is also installed on the housing, which can control the on / off state of the control circuit during the disassembly and assembly of the housing.

[0012] In the above-mentioned multi-wedge belt tension adjustment installation structure, the stop block includes a pressing part and a snap-fit ​​part at both ends thereon. The pressing part is movably inserted into the guide groove, so that the moving seat is pressed against the inner wall of the guide groove. A snap-fit ​​groove is formed between the snap-fit ​​part and the pressing part. The snap-fit ​​groove is snapped into the mounting frame, and the movement of the pressing part is restricted by the snap-fit ​​part.

[0013] In the above-mentioned multi-wedge belt tension adjustment installation structure, the locking component includes a locking nut and a locking screw. The locking nut is placed inside the movable seat, and a U-shaped groove is provided on the mounting frame. The locking screw passes through the U-shaped groove and is connected to the locking nut to restrict the movement of the movable seat relative to the guide groove.

[0014] In the above-mentioned multi-wedge belt tension adjustment installation structure, L-shaped blocks and positioning blocks are symmetrically arranged in the movable seat, and a placement cavity is formed between the L-shaped blocks. The two positioning blocks are arranged at an angle at the bottom of the placement cavity to restrict the locking screw in the placement cavity.

[0015] In the above-mentioned multi-wedge belt tension adjustment installation structure, the L-shaped stop block also forms a limiting cavity, which is connected to the placement cavity so that the locking screw can be extended into the limiting cavity.

[0016] In the above-mentioned multi-wedge belt tension adjustment installation structure, the output component includes a bearing and a multi-wedge belt pulley. The bearing is located inside the installation frame, and the multi-wedge belt pulley is provided with an output shaft. One end of the output shaft is connected to the inner ring of the bearing, and the other end is connected to the feed blade.

[0017] In the above-mentioned multi-wedge belt tension adjustment installation structure, the installation frame is also provided with several through slots, which allow the user to observe the installation position of the multi-wedge belt and the drive shaft.

[0018] The technical solution adopted by this utility model to solve its technical problem is to also propose a wood chipper, including one of the above-mentioned multi-wedge belt tension adjustment and installation structures.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The multi-wedge belt tension adjustment installation structure of this utility model sets the transmission component to be able to slide along the length direction of the installation frame, so that the tension of the multi-wedge belt can be directly adjusted by moving the transmission component. At the same time, the stop block is used to be engaged in the installation frame and abut against the side wall of the transmission component. With the help of the locking component, the transmission component is firmly locked, which effectively prevents the tension from loosening due to vibration during the operation of the equipment and ensures the long-term stable and reliable operation of the transmission system.

[0021] (2) The stop block adopts an integrated snap-fit ​​structure. It can be quickly installed and positioned by cooperating with the mounting frame through the snap-fit ​​groove. The clamping part can stably press the moving seat to ensure the reliability of the whole machine operation.

[0022] (3) The through slot allows users to visually inspect the wear condition, tension and installation of the multi-wedge belt without disassembling the housing, making it easier to detect abnormalities and carry out maintenance in a timely manner, improving the maintainability and transparency of the equipment and reducing the failure rate.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0038] like Figure 1 As shown, this solution mainly describes a multi-wedge belt 40 tension adjustment installation structure used in a wood chipper. However, the multi-wedge belt 40 tension adjustment installation structure is not limited to the case of wood chippers, but can also be applied to other equipment that uses multi-wedge belt 40 transmission.

[0039] like Figures 1 to 7 As shown, a multi-wedge belt 40 tension adjustment installation structure includes a housing 1, an output component 3, a transmission component 4, a stop block 5, and a locking component 6.

[0040] The housing 1 is equipped with a mounting frame 2; the output component 3 is fixed on the side wall of the mounting frame 2 and is driven by a multi-wedge belt 40 to drive the feeding blade 30 connected to the output component 3 to rotate; the transmission component 4 is movably located on the side of the mounting frame 2 away from the output component 3, and the tension of the multi-wedge belt 40 is adjusted when the transmission component 4 moves closer to or away from the output component 3 along the length direction of the mounting frame 2; the stop block 5 is movably engaged in the mounting frame 2 and moves against the side wall of the transmission component 4 so that the locking component 6 locks the transmission component 4 in the mounting frame 2.

[0041] like Figures 1 to 5 As shown, before assembling the transmission component 4, the worker can fix the output component 3 to the predetermined position of the mounting frame 2 (see reference). Figure 2(As shown in the left position), and ensure that it is set parallel to the transmission component 4; as the transmission component 4 is placed in the mounting frame 2, since it is slidably installed on the side of the mounting machine away from the output component 3, the transmission component 4 can drive the end of the multi-wedge belt 40 away from the output component 3 to move after the multi-wedge belt 40 is accurately installed in place, until the multi-wedge belt 40 is at a suitable tension. At this time, the worker can use the locking component 6 to restrict the transmission component 4 in the mounting frame 2, ensuring that the transmission component 4 will not slip when driving the output component 3 to rotate through the multi-wedge belt 40. At the same time, the worker can insert the stop block 5 into the limiting groove inside the mounting frame 2 in a movable snap-fit ​​manner, so that it abuts against the side wall of the transmission component 4. With the locking force of the locking component 6, the position of the transmission component 4 is completely fixed, the multi-wedge belt 40 maintains a constant tension, and prevents the transmission component 4 from axial displacement due to vibration or reverse torque during operation. Therefore, this embodiment movably mounts the transmission component 4 on the mounting frame 2 and adjusts the tension of the multi-wedge belt 40 by adjusting the distance between it and the output component 3. The structure is simple and easy to operate. With the dual limiting and locking functions of the stop block 5 and the locking component 6, the transmission component 4 can be stably fixed after adjustment, effectively preventing loosening or deviation caused by vibration during operation, improving the reliability and safety of the transmission system, extending the service life of the multi-wedge belt 40, and ensuring the smoothness of the transmission of the cutting blade 30.

[0042] The transmission component 4 includes: a movable seat 41, a guide groove 20 is provided along the length of the mounting frame 2, and the movable seat 41 is movably disposed in the guide groove 20; a guide wheel 42 and a drive component 43, an air guide cavity 410 is formed in the movable seat 41, and the guide wheel 42 is rotatably disposed in the air guide cavity 410; the drive component 43 is mounted on the outer wall of the movable seat 41, and the drive shaft of the drive component 43 is connected to the guide wheel 42 and extends to the outside of the mounting frame 2 to adjust the tension of the multi-wedge belt 40.

[0043] like Figures 2 to 5 As shown, in this embodiment, the movable seat 41 serves as the bearing base of the transmission component 4, and is movably disposed within the guide groove 20 of the mounting frame 2, and can move along the length direction of the mounting frame 2 (i.e., Figure 3 The sliding mechanism (left and right) serves to guide and adjust the limits. Furthermore, this embodiment integrates an air guide cavity 410 and a guide impeller within the movable seat 41, effectively guiding the airflow during the chipper's operation, improving heat dissipation efficiency, and preventing overheating. The externally mounted drive component 43 and extended drive shaft design allow users to directly operate the movable seat 41 to slide along the guide groove 20, enabling tool-free and rapid adjustment of the multi-wedge belt 40 tension. Tensioning can be completed without disassembling the housing 1, greatly improving maintenance convenience and work efficiency.

[0044] Preferably, such as Figure 6As shown, the inner wall of the guide cavity in this embodiment adopts an Archimedes spiral. This design helps to form wind pressure in the guide cavity, reduce flow resistance and energy loss, avoid the formation of local eddies and dead zones, thereby improving the working efficiency of the air guide cavity 410.

[0045] The stop block 5 includes a pressing part 50 and a latching part 51 at both ends thereon. The pressing part 50 is movably inserted into the guide groove 20, so that the moving seat 41 is pressed against the inner wall of the guide groove 20. A latching groove 520 is formed between the latching part 51 and the pressing part 50. The latching groove 520 latches onto the mounting frame 2 and restricts the movement of the pressing part 50 by the latching part 51.

[0046] like Figure 3 and Figure 4 As shown, the specifications of the clamping part 50 in this embodiment can be manufactured according to actual usage requirements. After the movable seat 41 is tightened by the locking member 6, the worker can quickly install and position it by cooperating with the mounting frame 2 through the snap-fit ​​groove 520, ensuring that the clamping part 50 is stably pressed against the side wall of the movable seat 41, further ensuring that the movable seat 41 and its driving member 43 will not move. It should be noted that the stop block 5 in this embodiment adopts an integrated snap-fit ​​structure, which ensures the stability of the movable seat 41 without additional fasteners, simplifies the assembly process, reduces manufacturing costs, and at the same time ensures the long-term stability of the position of the transmission member 4, improving the reliability of the whole machine operation. Preferably, this embodiment can also provide a locking hole 510 in the snap-fit ​​part 51. Through the cooperation of the locking hole 510 and the screw / bolt, the entire stop block 5 is fixed in the mounting frame 2, improving the stability of the movable seat 41 after fastening.

[0047] The locking component 6 includes a locking nut 60 and a locking screw 61. The locking nut 60 is placed inside the movable seat 41. A U-shaped groove 21 is provided on the mounting frame 2. The locking screw 61 passes through the U-shaped groove 21 and is connected to the locking nut 60 to restrict the movement of the movable seat 41 relative to the guide groove 20.

[0048] like Figures 6 to 7 As shown, as the movable seat 41 moves the drive component 43, and the tension of the multi-wedge belt 40 meets the required usage requirements (i.e., after the tension is adjusted), the worker begins to tighten the locking screw 61. As the locking screw 61 is gradually tightened, its head presses against the outer wall of the U-shaped groove 21, thereby using the resulting tension to lock the movable seat 41 into the mounting frame 2. This structure balances adjustment flexibility with locking reliability, and after adjustment, tightening securely locks the movable seat 41, avoiding the cumbersome operation of multiple disassemblies and reassemblies required in traditional fixing methods, thus improving maintenance efficiency.

[0049] The movable base 41 is symmetrically provided with L-shaped stops 411 and positioning blocks 412. A placement cavity 411a is formed between the L-shaped stops 411. The two positioning blocks 412 are set at an angle at the bottom of the placement cavity 411a to restrict the locking screw 61 within the placement cavity 411a.

[0050] like Figure 7 As shown, in this embodiment, the placement cavity 411a formed by the L-shaped stop 411 provides space for the placement of the locking nut 60. During placement, the positioning block 412, which is set at an angle at the bottom, limits the space of the locking nut 60, ensuring that it remains stable in a vertical position without rotation or tilting. The outer shell frame structure on the moving base 41 ensures that the locking nut 60 will not fall out of the placement cavity 411a. The overall structure requires no additional screws or other connecting parts, facilitating installation and disassembly, and greatly simplifying subsequent maintenance and replacement. Therefore, this structure effectively avoids displacement of the transmission component 4 caused by loose screws, enhances the vibration resistance of the entire tensioning system, and improves the safety and durability of the equipment.

[0051] The L-shaped stop 411 also forms a limiting cavity 411b, which is connected to the placement cavity 411a so that the connecting locking screw 61 can extend into the limiting cavity 411b.

[0052] like Figure 7 As shown, in this embodiment, the limiting cavity 411b provides additional accommodating space for the head of the locking screw 61, preventing it from protruding from the outer surface of the movable seat 41 during locking and avoiding interference with other components. Furthermore, the insertion and engagement between the head of the locking screw 61 and the limiting cavity 411b further restricts the movable seat 41 from wobbling or shifting in the direction perpendicular to its movement. This structure optimizes the internal space layout of the movable seat 41, enhancing its compactness and aesthetics.

[0053] The output component 3 includes a bearing 31 and a multi-ribbed pulley 32. The bearing 31 is located inside the mounting frame 2. The multi-ribbed pulley 32 is provided with an output shaft 320. One end of the output shaft 320 is connected to the inner ring of the bearing 31, and the other end is connected to the feed blade 30.

[0054] like Figure 2 and Figure 3 As shown, the output component 3 uses a bearing 31 to support the multi-wedge pulley 32 and the output shaft 320, ensuring smooth rotation and low friction loss, effectively reducing vibration and noise. The output shaft 320 is directly connected to the cutting blade 30, resulting in a short transmission path, high efficiency, and precise and reliable power transmission, improving the cutting efficiency and stability of shredding operations, while also facilitating blade replacement and maintenance. It should be noted that the installation of this output component 3 is the same as the traditional structure and working principle, and will not be described in detail here.

[0055] The mounting frame 2 is also provided with several through slots 22, which allow the user to observe the mounting positions of the multi-wedge belt 40 and the drive shaft.

[0056] like Figure 1 As shown, the through groove 22 in this embodiment is provided in two places, one of which is close to the drive shaft of the drive component 43, and the other is close to one side of the multi-wedge pulley 32 in the radial direction. This design allows users to intuitively check the wear condition, tension and installation status of the multi-wedge belt 40 without disassembling the housing 1, which facilitates timely detection of abnormalities and maintenance, achieves preventive maintenance, extends the life of key components, improves the maintainability and transparency of the equipment, reduces the failure rate, and improves the safety and user experience.

[0057] like Figure 1 As shown, a micro switch 10 is also installed on the housing 1. The micro switch 10 controls the on / off state of the circuit when the housing 1 is disassembled. When the housing 1 is disassembled, the micro switch 10 automatically cuts off the main circuit power supply. This structure replaces the complex power-off structure in traditional wood chippers, greatly reducing manufacturing costs. At the same time, it meets the requirement of power-off when the cover (the cover of the housing 1) is opened, significantly improving operational safety and complying with the national mandatory requirements for the safety protection of power tools.

[0058] It should be noted that the driving component 43 in this embodiment can be replaced by other driving devices such as stepper motors and servo motors.
