[0002] In bamboo charcoal production, the crushing and processing of bamboo raw materials is a key step that determines the subsequent carbonization efficiency and product quality.

[0003] Current general-purpose crushing equipment has obvious limitations: single-stage crushing is difficult to process the tough fibers of bamboo, often resulting in long fiber residues and large particle size deviations, requiring secondary crushing and causing process redundancy; crushing and refining components mostly use independent power sources, resulting in high energy consumption and poor synchronization; feeding mechanisms are mostly designed with a fixed inclination angle, and bamboo is prone to rolling or jamming, causing feeding congestion. These problems lead to low crushing efficiency and high energy consumption of bamboo charcoal raw materials, making it difficult to meet the needs of large-scale production.

[0004] To solve the above problems, there is an urgent need to develop a special equipment that combines high-efficiency crushing, uniform particle size, adaptive feeding, and low energy consumption. Therefore, this utility model is designed as a rapid crushing device for raw materials in bamboo charcoal production. Utility Model Content

[0018] 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.

[0019] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a rapid crushing device for raw materials used in bamboo charcoal production, comprising a crusher shell 1 and four support legs 2. The four support legs 2 are fixedly connected to the four corners of the bottom of the crusher shell 1, forming a stable support frame and lifting the equipment off the ground, facilitating the placement of a collection container below the discharge port. Anti-slip pads are welded to the bottom of the support legs 2 to increase friction with the ground and prevent vibration and displacement during equipment operation. The top of the crusher shell 1 is provided with a feed inlet, and the bottom is provided with a discharge port. The crusher shell 1 is equipped with a crushing component and a cutting component inside, and the feed component is provided on the right side of the crusher shell 1.

[0020] Reference Figure 1 , Figure 2 , Figure 5 The feeding assembly includes a hydraulic rod 5 and a movable plate 6. A fixed plate 4 is fixedly connected to the middle of the two support legs 2 on the left side of the crusher housing 1. The surface of the fixed plate 4 is parallel to the ground, providing a stable installation reference for the hydraulic rod 5 and ensuring that the force direction of the hydraulic rod 5 is vertical, thereby improving the pushing stability. The hydraulic rod 5 is fixedly connected to the upper surface of the fixed plate 4, with its output end facing upward, providing vertical thrust. A fixed block 11 is fixedly connected to its output end. The movable plate 6 is a long strip steel plate, the length of which can cover the feed inlet to the external feeding area. The movable plate 6 is rotatably connected to the front and rear inner walls of the crusher housing 1 by a round rod 8. The round rod 8 is a rotating shaft, allowing the movable plate 6 to rotate up and down around the shaft to adjust the feeding angle. The round rod 8 is located on the part of the movable plate 6 near the left side.

[0021] Reference Figure 2 - Figure 4 The lower surface of the movable plate 6 is provided with a transverse groove 10. The length of the groove 10 is adapted to the displacement requirements when the movable plate 6 rotates. The groove 10 is fixedly connected to a U-shaped block 9 with the opening direction facing downward through a matching slider. The U-shaped block 9 wraps around the top of the fixed block 11, and the two are rotatably connected by a cylinder passing through them laterally. When the hydraulic rod 5 extends or retracts, the U-shaped block 9 slides along the groove 10 and drives the movable plate 6 to rotate around the cylindrical rod 8, converting the vertical movement of the hydraulic rod 5 into the angle adjustment of the movable plate 6. The top of the fixed block 11 is set as a rounded and smooth convex curved surface, which can reduce the contact friction with the U-shaped block 9, making the transmission smoother when the movable plate 6 rotates and avoiding jamming.

[0022] Reference Figure 3 - Figure 5Multiple through slots are provided at the far left end of the movable plate 6. The width of the through slots is slightly larger than the diameter of the crushing wheel 16, and the depth extends through the thickness of the movable plate 6. When the movable plate 6 rotates downwards and approaches the crushing component, the through slots can accommodate the edge of the crushing wheel 16, preventing the movable plate 6 from directly contacting the crushing wheel 16 and causing collisions or wear. In addition, multiple placement grooves are provided on its upper surface to accommodate bamboo materials of different diameters, increasing the friction between the raw material and the plate surface, preventing rolling, and improving the stability of feeding. On the upper left and right sides of the movable plate 6, there are binding straps 7. The binding straps 7 are made of wear-resistant canvas material, and the inner side has rubber strips to increase the friction with the bamboo raw material, which is used to fix the raw material and prevent the raw material from slipping quickly due to the rotation of the movable plate 6 during feeding.

[0023] Reference Figure 1 - Figure 3 The crushing assembly includes crushing rollers 15 and a Y160M-4 motor 3. The two crushing rollers 15 are symmetrically rotated and installed inside the crusher housing 1, and their installation direction is consistent with the installation direction of the round rod 8. Multiple crushing wheels 16 are provided on the circumferential surface of the two crushing rollers 15. The two crushing rollers 15 are both located below the round rod 8 to receive the raw materials sliding down from the movable plate 6. The crushing wheels 16 on the two crushing rollers 15 are arranged in a staggered manner to prevent bamboo raw materials from leaking through the gaps and to ensure that each piece of raw material can be bitten and processed by the crushing wheels 16, thereby enhancing the shearing and compression capabilities of the bamboo.

[0024] Reference Figure 1 , Figure 3 , Figure 4 The foremost end of the crushing roller 15 on the left penetrates the outer wall of the crusher housing 1 and a drive gear 13 is fixedly connected to its circumferential surface. The foremost end of the crushing roller 15 on the right penetrates the outer wall of the crusher housing 1 and a driven gear 14 is fixedly connected to its circumferential surface. The drive gear 13 and the driven gear 14 mesh with each other to ensure that the two crushing rollers 15 rotate synchronously in opposite directions, forming opposing shearing forces.

[0025] Reference Figure 1 , Figure 3 , Figure 4 The drive gear 13 and the driven gear 14 are surrounded by a protective shell 12. The rear end of the protective shell 12 is bolted to the front surface of the crusher shell 1 to prevent debris from being rolled in when the gears rotate, and to ensure the safety of the operator. The motor 3 is fixedly connected to the front side of the protective shell 12 and its output end is fixedly connected to the front end of the crushing roller 15 through the inner wall of the protective shell 12 to provide power to the crushing roller 15. The two rollers are driven to rotate synchronously through gear transmission.

[0026] Reference Figure 3 - Figure 5The cutting component is located below the crushing component and receives the crushed coarse material for secondary refinement. It includes two cutting rollers 17, which are symmetrically distributed and each has multiple cutting blades 18 on its circumferential surface. The blades are sharp and wear-resistant alloy sheets arranged radially. The cutting blades 18 on the two cutting rollers 17 are arranged in an interlaced manner to form a fine cutting gap, further crushing the coarsely crushed bamboo material to a uniform particle size. The front ends of the two cutting rollers 17 are rotatably connected to the front inner wall of the crusher housing 1, and the rear ends penetrate the outer wall of the crusher housing 1.

[0027] Reference Figure 3 , Figure 4 The rear ends of the two crushing rollers 15 penetrate the outer wall of the crusher housing 1, and the circumferential surfaces of the two rollers are fixedly connected to the first conveyor wheel 19. The two first conveyor wheels 19 are connected to the second conveyor wheel 20 through the conveyor belt 21. The inner walls of the two second conveyor wheels 20 are fixedly connected to the rear circumferential surface of the cutting roller 17. The power of the crushing roller 15 is used to synchronously drive the cutting roller 17 to rotate, realizing the linkage of crushing and cutting processes, reducing the power source setting and reducing energy consumption.

[0028] Working principle: When in use, first place the collection container below the discharge port at the bottom of the crusher shell 1. The anti-slip pads at the bottom of the support legs 2 are in close contact with the ground to ensure stable operation of the equipment. Start the motor 3. The output end of the motor 3 drives the left crushing roller 15 to rotate. Through the meshing transmission of the drive gear 13 and the driven gear 14, the right crushing roller 15 rotates synchronously in the opposite direction. The crushing wheels 16 on the circumferential surfaces of the two rollers form an interlaced shearing state. At the same time, the first conveyor wheel 19 at the rear end of the crushing roller 15 drives the second conveyor wheel 20 through the conveyor belt 21, which drives the two cutting rollers 17 to rotate synchronously in the opposite direction. The cutting blades 18 are in an interlaced cutting state. The protective shell 12 provides safety protection for the gear and conveyor wheel assembly.

[0029] Subsequently, the bamboo raw material is placed into the placement groove on the upper surface of the movable plate 6, and then the binding straps 7 on the left and right sides are used to fix the raw material to prevent it from slipping off due to the rotation of the movable plate 6 during feeding. The hydraulic rod 5 is activated. When the output end of the hydraulic rod 5 extends, the upper convex curved surface of the top of the fixed block 11 drives the U-shaped block 9 to slide to the right along the slide groove 10 on the lower surface of the movable plate 6, so that the movable plate 6 rotates upward around the round rod 8 until the appropriate feeding angle is reached.

[0030] When the bamboo raw material slides down the movable plate 6 between the two crushing rollers 15, due to the transmission of the driving gear 13 and the driven gear 14, the two rollers rotate synchronously in opposite directions. The staggered crushing wheels 16 shear and squeeze the bamboo, crushing the thick and long bamboo into blocky coarse material.

[0031] The crushed coarse material falls to the cutting assembly. Two cutting rollers 17 rotate continuously under the linkage of the first conveyor wheel 19, the conveyor belt 21, and the second conveyor wheel 20. The interlaced cutting blades 18 on their surfaces perform secondary refining of the coarse material, forming bamboo charcoal raw materials with uniform particle size. Finally, the refined raw material falls into a collection container through the discharge port at the bottom of the crusher casing 1, completing the rapid crushing operation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
