Abstract
Description
Technical Field
[0001] This utility model relates to the field of material loading, unloading and stacking technology, and in particular to a mechanism for reducing the height of a curved boom crane stacking wood chips. Background Technology
[0002] The purpose of the articulated boom crane's wood chip stack height reduction mechanism is to lower the height of the wood chip stack through the lifting and swinging movements of the articulated boom structure, making it suitable for subsequent storage, transportation, or processing. On the one hand, this improves warehouse space utilization and facilitates centralized management of wood chips; on the other hand, it optimizes logistics processes, reducing transportation inconveniences and safety hazards caused by excessively high stacks; simultaneously, precise height reduction operations ensure the stability of the wood chip stack, avoiding the risk of collapse, improving the safety and efficiency of production operations, and providing support for the smooth operation of the wood processing industry chain.
[0003] In traditional wood chip stack height reduction operations, excavators are often relied upon to climb from the ground to the top of the stack to perform the operation. The excavator uses its tracks to traction to drive up the slope of the wood chip stack, and uses a hydraulic system to operate the bucket to dig out the material layer by layer from the top, and then dumps the material into the low-lying areas of the stack to fill them.
[0004] In existing technologies, some wood chip stack height reduction operations involve excavators climbing to the top of the stack, using the bucket to dig out the wood chips from the higher areas, and filling the lower areas of the stack with the material to reduce the height of the stack. However, climbing the stack and repairing the path require high driver skills, and improper handling can easily lead to the safety risk of equipment tipping over. In addition, excavators cannot operate on the stack when it is wet and slippery, and equipment on the stack cannot be removed, which seriously affects production efficiency. Therefore, a boom crane wood chip stack height reduction mechanism is proposed to solve the above problems. Utility Model Content

[0029] 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.
[0030] Reference Figures 1 to 3This utility model provides an embodiment of a boom arm 13 lifting and reducing mechanism for stacking timber chips, including a boom arm 1. The boom arm 1 is the main load-bearing and transmission component of the entire mechanism. A connecting rod 3 is rotatably connected to the outer wall of the boom arm 1. The connecting rod 3 and the boom arm 1 are rotatably connected to form a movable connection node, which facilitates the transmission of power and the change of movement direction. The other end of the connecting rod 3 is rotatably connected to a direction adjustment rod 4. The direction adjustment rod 4 is used to connect the connecting rod 3 and the boom arm connecting base 5 to realize the conversion of movement direction and angle adjustment. The bottom of the direction adjustment rod 4 is rotatably connected to the boom arm connecting base 5. The boom arm connecting base 5 is the basic structure connecting the boom arm 1 and the rotating component, and is used for support and torque transmission.
[0031] The inner wall of the stick connecting base 5 is rotatably connected to the bottom of the stick 1. The rotatable connection between the stick connecting base 5 and the bottom of the stick 1 allows the stick 1 to rotate around the bottom, realizing the pitching action of the mechanism. A rotary motor 6 is fixedly connected to the inner wall of the stick connecting base 5. The rotary motor 6 provides power for the horizontal rotation of the action support 8 and the helical gear 9. A rotary gimbal 7 is fixedly connected to the outer wall of the rotary motor 6. The rotary gimbal 7 is used to install the action support 8 and transmit the rotational power of the rotary motor 6. A stick cylinder 2 is rotatably connected to the outer wall of the stick 1. The stick cylinder 2 drives the connecting rod 3 to rotate through the telescopic movement, realizing the height adjustment of one end of the stick connecting base 5.
[0032] The bottom of the slewing gimbal 7 is fixedly connected to an action bracket 8. The action bracket 8 is used to install the drive motor 12 and the helical gear 9. It is the direct component for performing the height reduction operation. The outer wall of the action bracket 8 is fixedly connected to the drive motor 12. The drive motor 12 provides power for the rotation of the helical gear 9, realizing the rotation and unloading of the suspended log. The inner wall of the boom connecting base 5 is rotatably connected to the bottom of the boom 1. This rotatable connection is emphasized again to ensure the flexibility of the mechanism's movement. The top of the slewing gimbal 7 is rotatably connected to the bottom of the boom connecting base 5. The rotatable connection between the slewing gimbal 7 and the bottom of the boom connecting base 5 allows the action bracket 8 to be adjusted in the horizontal direction.
[0033] Reference Figures 1 to 3The other end of the boom 1 is rotatably connected to the crank arm 13. The crank arm 13 is rotatably connected to the boom 1. The boom 1 moves by raising or lowering the crank arm 13, thereby adjusting the height of the entire mechanism. The drive end of the drive motor 12 is fixedly connected to the helical gear 9. The helical gear 9 is driven to rotate by the drive motor 12 and is the core component for realizing the rotation and unloading of the suspended log. The top of the slewing platform 7 is detachably connected to the connecting plate 11. The detachable connection of the connecting plate 11 facilitates the installation, debugging and maintenance of the equipment. The outer wall of the connecting plate 11 is fixedly connected to the outer wall of the boom connecting base 5. The connecting plate 11 fixes the boom connecting base 5 and the slewing platform 7 into a whole, ensuring the stability of power transmission. The inner wall of the connecting plate 11 is threaded with multiple fixing screws 10. The multiple fixing screws 10 are used to enhance the firmness of the connection and ensure the stability of the mechanism during operation.
[0034] Two of the fixing screws 10 are threaded on the outer wall of the stick connecting base 5. These two fixing screws 10 fix the connecting plate 11 to the stick connecting base 5, forming part of the connection structure. The other end of the stick cylinder 2 is rotatably connected to the inner wall of the connecting rod 3. The stick cylinder 2 and the connecting rod 3 are rotatably connected, so that the extension and retraction movement of the stick cylinder 2 can be converted into the rotational movement of the connecting rod 3. The other two fixing screws 10 are threaded on the outer wall of the rotary gimbal 7. These two fixing screws 10 fix the connecting plate 11 to the rotary gimbal 7, completing the connection and fixation of the stick connecting base 5 and the rotary gimbal 7. The bottom of the boom 13 is rotatably connected to the body 14. The body 14 is the supporting foundation of the entire equipment, providing installation and power source for the boom 13 and other components. The other end of the helical gear 9 is rotatably connected to the inner wall of the action bracket 8. The helical gear 9 is rotatably connected to the inner wall of the action bracket 8, ensuring the stability and reliability of the helical gear 9 when rotating.
[0035] Working principle: When it is necessary to reduce the height of the stack of wood chips, the machine body 14 starts the boom 13, which raises the boom 13. The raising of the boom 13 drives the stick 1 to rise. The stick cylinder 2 on the outer wall of the stick 1 starts, which drives the connecting rod 3 to rotate. The rotation of the connecting rod 3 causes one end of the stick connecting base 5 to rise or fall. When it is necessary to adjust the angle, the rotary motor 6 starts. The starting of the rotary motor 6 drives the action bracket 8 to rotate. The rotation of the action bracket 8 drives the bottom spiral toothed plate 9 to adjust the horizontal angle, which is convenient for reducing the height at different angles. At this time, the drive motor 12 starts, which drives the spiral toothed plate 9 to rotate. The rotation of the spiral toothed plate 9 drives the stack of wood chips to rotate and unload, thereby achieving the goal of quickly reducing the height of the stack of wood chips.
