Technical Field

[0001] This utility model relates to the field of wood processing equipment, specifically an adjustable wood shredder. Background Technology

[0002] In the wood processing industry, wood chipping is a crucial process, widely used in various fields such as engineered wood products manufacturing, biomass energy production, and papermaking raw material preparation. With the continuous changes and diversification of market demands, the specifications for wood chippers are becoming increasingly complex.

[0003] Traditional wood shredders mostly have fixed structures, making it difficult to adjust the position of their crushing components and crushing parameters according to actual needs. This results in traditional shredders being unable to adapt flexibly to different types and sizes of wood, or to production scenarios requiring different sizes of chips. For example, when producing products with high requirements for chip size, traditional shredders may not be able to crush the wood to the ideal particle size; conversely, they are difficult to achieve when larger chips are needed for specific applications. Furthermore, the crushing efficiency of traditional shredders is often limited by their fixed structure, preventing them from fully utilizing the equipment's performance, leading to low production efficiency and increased production costs.

[0004] Therefore, this utility model provides an adjustable wood shredder. Utility Model Content

[0016] 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.

[0017] Please see Figures 1-4 As shown, an adjustable wood shredder includes a wood shredding structure 2, which includes a feed hopper 22. A crushing structure 24 is fixed inside the feed hopper 22. Limiting grooves 23 are symmetrically opened on both sides of the feed hopper 22. The crushing structure 24 can be slidably adjusted within the limiting grooves 23. The limiting grooves 23 consist of a set of straight grooves and several sets of sinking grooves. The sinking grooves and straight grooves are designed to be right angles to each other.

[0018] The crushing structure 24 includes a crushing plate 244. Two sets of adjusting rods 245 are symmetrically fixed on both sides of the crushing plate 244. The two sets of adjusting rods 245 are slidably connected to a fixed shaft 246. The two sets of adjusting rods 245 are slidably connected in the corresponding limiting grooves 23. A limiting plate 25 is fixedly connected to the rear side of the feed hopper 22. Two sets of limiting plates 25 are provided and symmetrically fixed to the rear side of the feed hopper 22. The two ends of the fixed shaft 246 are rotatably connected to the corresponding limiting plates 25 respectively.

[0019] It should be noted that when using the wood crushing structure 2 to crush wood, the position of the crushing plate 244 can be adjusted in multiple heights to meet different crushing needs. The higher the crushing plate 244 is, the larger the crushed pieces will be, and vice versa. When adjusting the position of the crushing plate 244, the adjusting rod 245 is pulled upward to disengage from the current recessed groove and enter the straight groove. Then it slides in the straight groove and then slides to the desired position in the recessed groove. When the adjusting rod 245 moves, it will also drive the crushing plate 244 to move, thereby realizing the position adjustment of the crushing plate 244. When the adjusting rod 245 moves, the fixed shaft 246 provides support to prevent the adjusting rod 245 from shaking or excessive displacement.

[0020] In one embodiment of this utility model, such as Figures 1-4 As shown, the crushing structure 24 also includes a rotating shaft 241. Two sets of protective blocks 242 are rotatably connected to both ends of the rotating shaft 241. A crushing main shaft 243 is centrally fitted on the outer wall of the rotating shaft 241. Several sets of inwardly recessed crushing grooves for crushing wood are opened on the surface of the crushing main shaft 243.

[0021] Specifically, when the rotating shaft 241 is driven to rotate, it will drive the crushing main shaft 243 to rotate synchronously. The gap between the crushing main shaft 243 and the crushing plate 244 is used to place the wood to be crushed. When the crushing main shaft 243 rotates, it will drive the wood to rotate and roll it into the gap. The crushing plate 244 contacts the wood to crush it.

[0022] In one embodiment of this utility model, such as Figures 1-4 As shown, a support base 247 is fixedly connected to the inner wall of the front end of the feed hopper 22, and a feed plate 248 is fixedly connected to the top of the support base 247. The feed plate 248 is a hollow semi-cylinder and is sleeved on the outside of the crushing main shaft 243. A gap is formed between the feed plate 248 and the crushing main shaft 243 for the wood to pass through.

[0023] Specifically, the crushed wood will be drawn into the gap between the crushing spindle 243 and the crushing plate 244 as the crushing spindle 243 rotates, then enter the gap between the feeding plate 248 and the crushing spindle 243, and then fall downwards, being discharged from the gap between the support bases 247.

[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, the contact end of the crushing plate 244 with the wood has a serrated structure, and the serrations correspond to the crushing groove of the crushing spindle 243. When the crushing spindle 243 rotates, the wood is crushed.

[0025] In one embodiment of this utility model, such as Figures 1-4As shown, a drive structure 1 is fixedly connected to one side of the wood chipping structure 2. The drive structure 1 includes a first support member 11. A drive motor 12 is fixedly connected to the top of the first support member 11. The output shaft of the drive motor 12 is connected to a sprocket via a chain drive. A hollow first protective shell 13 is fitted over the output shaft of the drive motor 12, the chain, and the sprocket. One end of the first protective shell 13 is fixedly connected to the drive motor 12, and the other end of the drive motor 12 is fixedly connected to a second protective shell 14. The sprocket is fixedly connected to a rotating shaft 241. The second protective shell 14 is fitted over the sprocket and the rotating shaft 241. The second protective shell 14 is fixed to the feed hopper 22 by a pin.

[0026] Specifically, in use, the wood is placed in the feed hopper 22, and the output shaft of the drive motor 12 drives the sprocket to rotate through the chain. The sprocket drives the rotating shaft 241 to rotate. When the rotating shaft 241 rotates, it drives the crushing main shaft 243 to rotate. The crushing main shaft 243 rotates the wood toward the crushing plate 244. The wood is crushed by the meshing of the crushing plate 244 and the crushing main shaft 243.

[0027] In one embodiment of this utility model, such as Figures 1-4 As shown, a second support member 21 is fixedly connected to the bottom end of the feed hopper 22, and the bottom ends of the second support member 21 and the first support member 11 are located on the same plane.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: When using the adjustable wood shredder of this invention, first place the wood in the feed hopper 22. Start the drive motor 12, and the output shaft of the drive motor 12 drives the sprocket to rotate via a chain. Since the sprocket is fixedly connected to the rotating shaft 241, the sprocket will drive the rotating shaft 241 to rotate. When the rotating shaft 241 rotates, the crushing main shaft 243 sleeved on its outer wall rotates synchronously.

[0030] A gap is formed between the crushing spindle 243 and the crushing plate 244. When the crushing spindle 243 rotates, it drives the wood placed in the feed hopper 22 to rotate and roll the wood into the gap. At this time, the serrated structure on the crushing plate 244 cooperates with the crushing groove on the crushing spindle 243 to crush the wood.

[0031] When the position of the crushing plate 244 needs to be adjusted according to different crushing requirements, the operator pulls the adjusting rod 245 upwards, causing it to disengage from its current recessed groove and enter the straight groove. Then, the adjusting rod 245 is slid within the straight groove to the corresponding recessed groove, and then locked into that groove. During the movement of the adjusting rod 245, the crushing plate 244 moves synchronously, thus adjusting its position. The higher the position of the crushing plate 244, the larger the gap between it and the crushing shaft 243, resulting in larger crushed fragments; conversely, the lower the position of the crushing plate 244, the smaller the crushed fragments.

[0032] The crushed wood, under the rotation of the crushing spindle 243, is first rolled into the gap between the crushing spindle 243 and the crushing plate 244, then enters the gap between the feeding plate 248 and the crushing spindle 243, and finally falls downwards and is fed out through the gap between the support bases 247, thus completing the fine crushing process of the wood. Each set of gaps can accommodate the largest size of the crushed wood to pass through.
