Description
Technical Field
[0001] This utility model relates to the field of wood board recycling technology, and in particular to a highly efficient crushing and reuse device for wood boards used in wood pallet recycling. Background Technology
[0002] The efficient crushing and reuse device for wooden pallet recycling boards is a mechanical device specifically designed for the automated crushing and processing of wooden boards from waste wooden pallets. In the process of wooden pallet recycling and reuse, board crushing is the core link to achieve resource recycling. Currently, it mainly relies on board crushers to crush the wooden boards from recycled wooden pallets.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In practical applications, existing wood board crushers often encounter material jamming and blockage problems during the crushing process due to uneven material of the wood pallets, possible impurities on the surface, or differences in the size of the wood boards. After the wood boards are put into the crusher's feed inlet, some wood chips and scraps tend to accumulate on the inner wall of the feed inlet or at the entrance of the crushing chamber. Especially when continuously processing wood pallet boards in batches, the accumulated material will gradually form a blockage, preventing subsequent wood boards from smoothly entering the crushing chamber. Frequent shutdowns for cleaning are required, which seriously reduces crushing efficiency and increases manual operation costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is that existing wood board crushers are prone to material jamming during crushing due to uneven material, impurities, or size differences in the wood boards of wooden pallets. In particular, when processing in batches, wood chips and scraps will accumulate and block the feed inlet or crushing chamber inlet. To address this, we propose an efficient crushing and reuse device for wood boards from wooden pallets.
[0005] To achieve the above objectives, this application adopts the following technical solution: a high-efficiency crushing and reuse device for wood pallet recycling, comprising a wood crusher and a support: the surface of the wood crusher is provided with a feed inlet, the bottom surface of the wood crusher is provided with a discharge outlet, the bottom surface of the wood crusher is fixedly connected to the support, and vibration devices are provided on both sides of the wood crusher. The vibration devices include two support plates, which are respectively fixedly connected to the two sides of the wood crusher. Two L-shaped plates are fixedly connected to the surface of the support plates. A motor is fixedly connected to the side of the two L-shaped plates that are close to each other. A drive shaft is fixedly connected to the output end of the motor. A cylinder is fixedly connected to one end of the drive shaft. Grooves are provided at both ends of the cylinder. A striking rod is slidably connected to the inner wall of the grooves at both ends of the cylinder. A striking ball is fixedly connected to one end of the striking rod. The arc surface of the striking ball is slidably connected to the wood crusher. The striking rod and the striking ball are made of elastic material.
[0006] Preferably, the striking rod has an insertion hole on its arc surface, and two threaded rods pass through the internal thread of the cylinder. The threaded surfaces of the threaded rods are threadedly connected to the insertion hole, and a rotating plate is fixedly connected to one end of the threaded rod.
[0007] Preferably, the arc surface of the rotating plate is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed in a circumferential array on the rotating plate.
[0008] Preferably, the arc surface of the striking rod is provided with an adjustment hole, and the inner wall of the adjustment hole is threadedly connected to the threaded rod.
[0009] Preferably, the inner wall of the bracket is provided with a collecting device, the collecting device including a fixed frame, the fixed frame being fixedly connected to the inner wall of the bracket, the surface of the fixed frame having a square hole, a collecting box being slidably connected to the inner wall of the square hole of the fixed frame, a limiting plate being fixedly connected to the surface of the collecting box, a through hole being provided on the surface of the limiting plate, a fixing plate being fixedly connected to the surface of the fixed frame, a fixing rod being slidably inserted into the fixing plate, the arc surface of the fixing rod being slidably connected to the through hole of the limiting plate, and a pull plate being fixedly connected to one end of the fixing rod.

[0011] Preferably, a handle is fixedly connected to the surface of the collection box.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, by setting a vibration device, the wood board crusher is prevented from getting stuck in the feed inlet during feeding. When the motor drives the transmission shaft to rotate the cylinder, the striking rods in the grooves at both ends move with the cylinder in a circular motion. The striking balls at their ends periodically hit the side wall of the wood board crusher. The striking rods and striking balls made of elastic material generate buffer vibrations when they hit, which not only avoids rigid damage to the machine body, but also transmits the vibration to the crushing chamber inside the crusher. This continuous vibration can effectively prevent wood chips and scraps from accumulating and clogging at the feed inlet, and can significantly improve the material flow efficiency.
[0014] In this invention, by setting up a collection device, the collection box is precisely positioned through the square hole of the fixing frame, which can directly receive the crushed material falling from the discharge port of the wood board crusher, preventing the material from scattering on the ground, reducing wood loss, and reducing the workload of subsequent cleaning workshop. When it is necessary to empty the collection box, simply pull the pull plate to pull out the fixing rod from the through hole of the limiting plate, release the fixing of the collection box, and then pull the collection box directly out through the square hole to transfer the material, thereby improving the overall process efficiency of wood pallet crushing and reuse.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] Reference Figures 1-6As shown, this utility model provides a technical solution: a high-efficiency crushing and reuse device for wood pallet recycling, including a wood crusher 1 and a support 2. The surface of the wood crusher 1 is provided with a feed inlet, and the bottom surface of the wood crusher 1 is provided with a discharge outlet. The bottom surface of the wood crusher 1 is fixedly connected to the support 2. Vibration devices 3 are provided on both sides of the wood crusher 1. The vibration devices 3 include two support plates 301, which are fixedly connected to both sides of the wood crusher 1 respectively. Two L-shaped plates 302 are fixedly connected to the surface of the support plates 301. A motor 303 is fixedly connected to the side of the two L-shaped plates 302 that is close to each other. A drive shaft 304 is fixedly connected to the output end of the motor 303. A cylinder 305 is fixedly connected to one end of the 4. Grooves are provided at both ends of the cylinder 305. A striking rod 306 is slidably connected to the inner wall of each groove. A striking ball 307 is fixedly connected to one end of each striking rod 306. The arc surface of the striking ball 307 is slidably connected to the wood board crusher 1. The striking rod 306 and the striking ball 307 are made of elastic material. By setting a vibration device 3, the wood board crusher 1 is prevented from getting stuck in the feed inlet during feeding. When the motor 303 drives the transmission shaft 304 to rotate the cylinder 305, the striking rod 306 in the grooves at both ends moves circumferentially with the cylinder 305. The striking ball 307 at its end periodically impacts the side wall of the wood board crusher 1. The striking rod 306 and striking ball 307 generate buffering vibrations upon impact, which not only avoids rigid damage to the machine body but also transmits the vibration to the crushing chamber inside the crusher. This continuous vibration effectively prevents sawdust and wood chips from accumulating and clogging at the feed inlet, significantly improving material flow efficiency. The inner wall of the support 2 is equipped with a collecting device 4, which includes a fixed frame 41. The fixed frame 41 is fixedly connected to the inner wall of the support 2. A square hole is formed on the surface of the fixed frame 41, and a collecting box 42 is slidably connected to the inner wall of the square hole. A limiting plate 43 is fixedly connected to the surface of the collecting box 42, and a through hole is formed on the surface of the limiting plate 43. A fixing plate 44 is fixedly connected to the surface of the fixed frame 41, and the fixing plate 44 slides within the fixing plate. A fixed rod 45 is inserted, and the arc surface of the fixed rod 45 is slidably connected to the through hole of the limiting plate 43. One end of the fixed rod 45 is fixedly connected to a pull plate 46. By setting up the collection device 4, the collection box 42 is accurately positioned through the square hole of the fixing frame 41, which can directly receive the crushed material falling from the discharge port of the wood board crusher 1, avoid the material from scattering on the ground, reduce wood loss, and reduce the workload of subsequent cleaning workshop. When the collection box 42 needs to be emptied, simply pull the pull plate 46 to pull the fixed rod 45 out of the through hole of the limiting plate 43, release the fixation of the collection box 42, and then pull the collection box 42 directly out along the square hole to transfer the material, thereby improving the overall process efficiency of wood pallet crushing and reuse.
[0025] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the arc surface of the striking rod 306 has an insertion hole 308, and two threaded rods 309 pass through the internal thread of the cylinder 305. The threaded surface of the threaded rod 309 is threadedly connected to the insertion hole 308. A rotating plate 310 is fixedly connected to one end of the threaded rod 309, which achieves the effect of quick disassembly and assembly of the striking rod 306 and the striking ball 307, facilitating their maintenance and replacement. When the elastic material striking rod 306 or striking ball 307 wears or ages due to long-term high-frequency striking, simply rotate the rotating plate 310 to drive the threaded rod 309 out of the insertion hole 308 of the striking rod 306, and the old striking rod 306 and striking ball 307 can be directly removed. When replacing new parts, simply align the threaded rod 309 with the insertion hole 308 and tighten it in the opposite direction to complete the fixation. The rotating plate 310 has several anti-slip grooves 311 on its arc surface. These grooves are evenly distributed in a circumferential array on the rotating plate 310. By setting the anti-slip grooves 311, the frictional resistance between the hand and the surface of the rotating plate 310 is increased. Even if the hand is covered with sawdust, oil, or sweat, slippage can be effectively avoided, significantly improving the efficiency of maintenance operations. The striking rod 306 has an adjustment hole 312 on its arc surface. The inner wall of the adjustment hole 312 is threaded to the threaded rod 309. By setting the adjustment hole 312, the length of the striking rod 306 and the striking ball 307 extending out of the cylinder 305 can be adjusted. As the extension length of the striking rod 306 increases, the striking force is also increased, which can effectively deal with thicker and harder wooden boards and ensure that the vibration can break up material blockages.
[0026] Reference Figure 5 and Figure 6 As shown in this embodiment: a spring 47 is fitted on the arc surface of the fixing rod 45. The two ends of the spring 47 are fixedly connected to the fixing plate 44 and the pull plate 46 respectively. Under the action of the spring 47, when the pull plate 46 is not pulled, the spring 47 is in a natural or slightly stretched state. Its elasticity will push the fixing rod 45 to automatically insert into the through hole of the limiting plate 43. This can prevent the fixing rod 45 from accidentally dislodging due to equipment vibration and other factors, and always keep the collection box 42 fixed, preventing the collection box 42 from shifting. A handle 48 is fixedly connected to the surface of the collection box 42. By setting the handle 48, force can be directly applied by holding the handle 48, and the collection box 42 can be easily pulled out or pushed in along the square hole of the fixing frame 41, avoiding the problem of difficulty in gripping the collection box 42 due to its smooth surface.
[0027] Working principle: When the vibration device 3 is needed, the motor 303 between the two L-shaped plates 302 is started. The output end of the motor 303 begins to rotate, and the power generated is transmitted to the drive shaft 304 connected to it. The drive shaft 304 precisely transmits the rotational motion of the motor 303 to the cylinder 305, causing the cylinder 305 to rotate at high speed. During the high-speed rotation of the cylinder 305, the striking rods 306 installed in the grooves at both ends of the cylinder will perform circular motion with the rotation of the cylinder 305. Since one end of the striking rod 306 is connected to the striking ball 307, when the striking rod 306 rotates with the cylinder 305, the striking ball 307 will continuously strike the side of the wood board crusher 1. The striking ball 307 at the end of the striking rod 306 periodically contacts and impacts the side of the wood board crusher 1 during the circular motion. The wall utilizes the deformation and rebound of elastic material to convert circular motion into high-frequency vibration, which is transmitted to the inside of the crusher. This vibration effectively prevents wood from accumulating and clogging in the feed inlet. When it is necessary to repair or replace the striking rod 306 and striking ball 307, the striking rod 306 is threadedly connected to the threaded rod 309 inside the cylinder 305 through the arc-shaped insertion hole 308. Rotating the rotating plate 310 can drive the threaded rod 309 to screw into or out of the insertion hole 308, realizing the quick replacement of the striking rod 306 and striking ball 307, which is convenient for maintenance and parts replacement. During this process, the arc-shaped surface of the rotating plate 310... The circumferential array of anti-slip grooves 311 increases hand friction, preventing slippage during rotation and ensuring effortless and stable adjustment or disassembly. When it is necessary to increase the vibration force of the striking ball 307, unscrew the threaded rod 309 from the insertion hole 308 and pull the striking rod 306 outward until the threaded rod 309 is aligned with the adjustment hole 312. Then screw the threaded rod 309 back into the adjustment hole 312 to lengthen the striking rod 306 extending beyond the cylinder 305, thereby increasing the contact force and frequency between the striking ball 307 and the side wall of the crusher. In summary, by setting up the vibration device 3, the wood board crushing effect is achieved. During feeding, to prevent wood chips from getting stuck in the feed inlet, the motor 303 drives the transmission shaft 304 to rotate the cylinder 305. The striking rods 306 in the grooves at both ends move in a circular motion with the cylinder 305. The striking balls 307 at their ends periodically hit the side wall of the wood chipper 1. The elastic material of the striking rods 306 and the striking balls 307 generates buffer vibration when they hit, which not only avoids rigid damage to the machine body, but also transmits the vibration to the crushing chamber inside the crusher. This continuous vibration can effectively prevent wood chips and scraps from accumulating and blocking at the feed inlet, and can significantly improve the material flow efficiency.
[0028] Working principle: The fixed frame 41 is fixed to the inner wall of the support 2. The square hole on its surface forms a fixed sliding track. The operator holds the handle 48 on the surface of the collection box 42 and pushes the collection box 42 along the square hole, so that the opening of the collection box 42 is precisely aligned with the discharge port of the wood shredder 1, ensuring that the shredded wood can fall directly into the box and preventing the material from scattering into the support 2. During the sliding process of the collection box 42, the limiting plate 43 on its surface moves synchronously. When the collection box 42 is pushed to its maximum depth, the limiting plate 43 is exactly aligned with the fixed plate 44 on the surface of the fixed frame 41. The perforation on the plate 43 coincides with the position of the fixing rod 45 on the fixing plate 44. A spring 47 is fitted onto the arc surface of the fixing rod 45. In its natural state, the spring 47 is in a slightly stretched state, and its elastic force will push the pull plate 46 towards the fixing plate 44, thereby causing the fixing rod 45 to pass through the perforation of the fixing plate 44 and insert into the perforation of the limiting plate 43. After the fixing rod 45 passes through the fixing plate 44 and the limiting plate 43, it firmly fixes the collection box 42 to the fixing frame 41. Even if the vibration device 3 of the wood shredder 1 generates high-frequency vibration, the collection box 42 will not be affected by the vibration. To prevent slippage or displacement and ensure stability during material collection, when the collection box 42 is full, the operator pulls the pull plate 46 away from the fixed plate 44. The pull plate 46 compresses the spring 47 and drives the fixed rod 45 to be pulled out from the through hole of the limit plate 43, releasing the fixing restriction on the collection box 42. After unlocking, the operator holds the handle 48 and pulls the collection box 42 out along the square hole of the fixing frame 41. At this time, the handle 48 provides a stable force point, making it easy to move the collection box 42 to the designated location to dump the material, completing one material recycling cycle. In summary... By setting up the collection device 4, the collection box 42 is accurately positioned through the square hole of the fixing frame 41, which can directly receive the crushed material falling from the discharge port of the wood board crusher 1, avoiding the material from scattering on the ground, reducing wood loss, and reducing the workload of subsequent cleaning workshop. When the collection box 42 needs to be emptied, simply pull the pull plate 46 to pull the fixing rod 45 out of the through hole of the limit plate 43, release the fixing of the collection box 42, and then pull the collection box 42 directly out through the square hole to transfer the material, thus improving the overall process efficiency of wood pallet crushing and reuse.
