Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulverizing technology, and in particular to a pulverizing device for litchi fruit wood charcoal with serrated blades. Background Technology
[0002] The blade-type lychee fruit charcoal crushing device is a key piece of equipment in the lychee fruit charcoal processing flow. Its function is to transform the blocky lychee fruit charcoal into a powder form with smaller particle size. In terms of market demand, its role is extensive and crucial.
[0003] The serrated blade of the litchi charcoal crushing device has a serrated structure. This serrated design allows the tip of the serration to contact the litchi charcoal first during operation, generating a powerful shearing force under high-speed rotation. Compared with ordinary flat blades, it is more efficient in crushing litchi charcoal. In gunpowder manufacturing, the serrated blade can accurately control the particle size of the crushed material, ensuring that the litchi charcoal powder meets the strict standards of gunpowder production and guaranteeing product quality and performance.
[0004] Current serrated blade litchi charcoal crushing devices use a single serrated shape. After prolonged use, the serrations wear down, their sharpness decreases, and crushing efficiency drops. Existing technologies use new composite materials to manufacture blades, adding wear-resistant alloying elements to the steel to improve the blades' hardness and wear resistance, thus increasing crushing efficiency. However, in terms of the overall device structure, when a large amount of litchi charcoal is fed in, the feed inlet may become clogged, affecting the continuity of the crushing operation.

Detailed Implementation
[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a serrated blade litchi charcoal crushing device, comprising a top plate 1, with support legs 3 fixedly connected to the four corners of the bottom of the top plate 1 to provide stable support for the entire device. A device housing 4 is fixedly connected to the top of the top plate 1, protecting the internal structure. A feed inlet 5 is provided at the top of the device housing 4 for feeding litchi charcoal to be crushed. A vibration groove 6 is provided on the inner wall of the feed inlet 5, providing a sliding track for a vibration frame 7. Vibration frames 7 are slidably connected to the left and right sides of the inner wall of the vibration groove 6, and vibration frames 7 are fixedly connected to the front, rear, left, and right ends of the inner wall of the vibration groove 6. Telescopic rod 2 8, vibrating telescopic rod 2 8 drives the vibrating frame 7 to vibrate by telescopic extension. The other ends of multiple vibrating telescopic rods 2 8 are respectively fixedly connected to the front and rear sides of the vibrating frame 7. Motors 9 are fixedly connected to the top left and right sides of the top plate 1 to provide power. The output ends of the two motors 9 are fixedly connected to the rotating shafts 10, which drive the serrated blades 11 to rotate. Multiple serrated blades 11 are fixedly connected to the outer walls of the two rotating shafts 10. The serrated blades 11 crush the fed litchi fruit wood charcoal. Multiple serrated blades 11 are all inside the outer shell 4 of the device. A screening mechanism 2 is set at the bottom of the top plate 1. The screening mechanism 2 is used to screen the litchi fruit wood charcoal after crushing.
[0033] Specifically, when using the serrated blade litchi charcoal crushing device, the litchi charcoal enters through the feed inlet 5 at the top of the device shell 4. Under the action of multiple vibrating telescopic rods 8 fixedly connected to the front, back, left, and right ends of the inner wall of the vibrating groove 6, it can reciprocate. Vibration can prevent the litchi charcoal from clogging at the feed inlet 5, allowing the material to enter the device more smoothly. The motor 9 fixedly connected to the top left and right sides of the top plate 1 starts to work. The output end of the motor 9 drives the rotating shaft 10 to rotate. Multiple serrated blades 11 fixedly connected to the outer wall of the rotating shaft 10 rotate at high speed along with the rotating shaft 10. The litchi charcoal that has entered the device shell 4 is gradually crushed under the high-speed cutting of the serrated blades 11. The serrated blade design can cut the litchi charcoal more efficiently. Compared with ordinary blades, it can break the charcoal into smaller particles, effectively avoiding the accumulation and clogging of litchi charcoal during the feeding process, ensuring that the material can enter the device continuously and stably, and ensuring that the crushing work is uninterrupted.
[0034] Reference Figure 1 , Figure 4 and Figure 5 The screening mechanism 2 includes a base plate 201, which provides support. The base plate 201 is located at the bottom of the top plate 1. A screening shell 202 is slidably connected to the top of the base plate 201, providing space for screening and collection. A first screening basket 203 is slidably connected to the upper part of the inner wall of the screening shell 202. The first screening basket 203 is used to screen out larger particles of pulverized material. A second screening basket 204 is slidably connected to the middle part of the inner wall of the screening shell 202. The second screening basket 204 is used to screen out medium-sized particles of pulverized material. A third collection basket 205 is slidably connected to the bottom of the inner wall of the screening shell 202. The third collection basket 205 is used to collect fine particles of pulverized material. The front left and right sides of the 2 are provided with slots 206, which provide the installation and sliding position for the sliding door 207. The inner walls of the two slots 206 are slidably connected to the sliding door 207, which facilitates the removal of materials from each screening basket. The top left and right sides of the bottom plate 201 are fixedly connected with fixing blocks 208, which are used to install and fix the first vibration telescopic rod 209. The adjacent side of the two fixing blocks 208 is fixedly connected with the first vibration telescopic rod 209. The first vibration telescopic rod 209 drives the screening shell 202 to vibrate by telescopic movement. The other ends of the two first vibration telescopic rods 209 are fixedly connected to the left and right sides of the screening shell 202 respectively.
[0035] Specifically, when the lychee fruit charcoal needs to be sieved after being crushed, the crushed lychee fruit charcoal falls from the top plate 1 into the screening shell 202, first contacting the first screening basket 203. The first screening basket 203, based on its larger screen aperture, performs initial screening of the material. Smaller particles that meet the requirements of the first screening basket 203's screen will pass through the screen and fall into the second screening basket 204 below, while larger particles remain on the first screening basket 203. The vibrating telescopic rod 209 will drive the screening shell 202 to reciprocate, and this vibration will cause the material to move more smoothly on the screening basket. The material is evenly distributed, improving screening efficiency and preventing material from accumulating in certain areas of the screen, which would lead to insufficient screening. After being screened by the first screening basket 203, the material falls into the second screening basket 204 for further screening. The screen mesh of the second screening basket 204 has a smaller aperture, which further refines the screening of the material. Smaller particles pass through the screen and fall into the third collection basket 205 at the bottom. The remaining material remains on the second screening basket 204. By opening the sliding door 207, the screened material can be easily removed, meeting the diverse needs of different application scenarios for the particle size of litchi fruitwood charcoal.
[0036] Reference Figure 1 , Figure 3 and Figure 4Limiting blocks 12 are fixedly connected to the bottom left and right sides of the vibration frame 7. The limiting blocks 12 can prevent the vibration frame 7 from shifting during vibration. Limiting grooves 13 are opened on the bottom left and right sides of the inner wall of the vibration groove 6 to limit the vibration frame 7. The two limiting blocks 12 are slidably connected to the corresponding limiting grooves 13. Triangular blocks 14 are fixedly connected to the adjacent sides of the two fixing blocks 208. The triangular blocks 14 can enhance the stability of the connection between the fixing blocks 208 and the base plate 201. The bottom of the two triangular blocks 14 is fixedly connected to the top of the base plate 201. A handle 15 is provided on the front side of the sliding door 207. The handle 15 facilitates the operator to open and close the sliding door 207. Screws 16 are rotatably connected to the left and right ends of the front side of the handle 15. The screws 16 are used to fix the handle 15 to the sliding door 207. The two screws 16 pass through the handle 15 and are threaded to the front side of the sliding door 207. The top of the top plate 1 has four Anti-collision corners 17 are fixedly connected at each corner. Anti-collision corners 17 can prevent the corners of the top plate 1 from being damaged by collisions during the handling and use of the device. All anti-collision corners 17 are made of rubber material, which has good cushioning performance. Protective sleeves 18 are fixedly connected to the bottom of the support legs 3. Protective sleeves 18 can protect the bottom of the support legs 3 and reduce wear. The outer walls of the protective sleeves 18 are roughened. The roughened outer walls can increase the friction with the ground and make the device more stable. A controller 19 is fixedly connected to the right side of the top front of the top plate 1. The controller 19 facilitates the operator to centrally control the device. The controller 19 is electrically connected to two vibrating telescopic rods 209, two motors 9 and multiple vibrating telescopic rods 8. The speed of the motor 9 and the extension frequency and amplitude of the vibrating telescopic rods 209 and 8 can be adjusted through the controller 19.
[0037] Specifically, the limiting block 12 is fixed to the bottom of the vibrating frame 7 and can cooperate with the limiting groove 13 to limit the vibration range of the vibrating frame 7, ensuring that it vibrates stably within the specified path and preventing deviation, shaking, or even dislodging from the vibrating groove 6 during vibration, thus ensuring the stability and safety of the device. The triangular block 14 is connected between the fixed block 208 and the base plate 201, which can enhance the connection strength and stability between the fixed block 208 and the base plate 201, improve the structural strength of the entire screening mechanism 2, and ensure that the fixed block 208 will not loosen or shift during vibration. The handle 15 is installed on the front side of the sliding door 207, providing a force point for the operator, making it convenient for the operator to pull the sliding door 207 by holding the handle 15 to open and close the sliding door 207, making operation more convenient. The anti-collision corners 17 are fixed at the four corners of the top of the top plate 1, made of rubber material, and have good elasticity. To ensure stability and cushioning performance, a protective sleeve 18 is installed at the bottom of the support leg 3. The outer wall is roughened to protect the bottom of the support leg 3 and prevent it from being damaged when in contact with the ground, thus extending the service life of the support leg 3. The roughened outer wall can increase the friction with the ground, making the device more stable during placement and operation. The controller 19 is the control core of the device. It is electrically connected to two vibrating telescopic rods 209, two motors 9, and multiple vibrating telescopic rods 8. It realizes the speed control of motor 9, thereby adjusting the rotation speed of the saw blade 11 to adapt to the pulverization requirements of litchi fruit wood charcoal with different hardness and particle size. At the same time, it can also control the extension frequency and amplitude of the vibrating telescopic rods 209 and 8, so that the vibration of the screening mechanism 2 and the vibration of the feed inlet 5 reach the optimal state, ensuring the pulverization and screening effect of litchi fruit wood charcoal and realizing the automation and precise control of the device.
[0038] Working principle: When using the serrated blade litchi charcoal crushing device, the litchi charcoal enters through the feed inlet 5 at the top of the device shell 4. Under the action of multiple vibrating telescopic rods 8 fixedly connected to the front and rear sides and left and right ends of the inner wall of the vibrating groove 6, it can reciprocate. The vibration can prevent the litchi charcoal from being blocked at the feed inlet 5, allowing the material to enter the device more smoothly. The motor 9 fixedly connected to the top left and right sides of the top plate 1 starts to work. The output end of the motor 9 drives the rotating shaft 10 to rotate. Multiple serrated blades 11 fixedly connected to the outer wall of the rotating shaft 10 rotate at high speed together with the rotating shaft 10. The litchi charcoal entering the device shell 4 is gradually crushed under the high-speed cutting of the serrated blades 11. The serrated blade design can cut the litchi charcoal more efficiently. Compared with ordinary blades, it can break the charcoal into smaller particles, effectively avoiding the accumulation and blockage of litchi charcoal during the feeding process, ensuring that the material can enter the device continuously and stably, and ensuring that the crushing work is uninterrupted.
[0039] Furthermore, when the lychee fruit charcoal needs to be sieved after being crushed, the crushed lychee fruit charcoal falls from the top plate 1 into the screening shell 202, first contacting the first screening basket 203. The first screening basket 203 performs initial screening of the material based on its larger screen aperture. The smaller particles that meet the requirements of the first screening basket 203 will pass through the screen and fall into the second screening basket 204 below, while the larger particles remain on the first screening basket 203. The vibrating telescopic rod 209 will drive the screening shell 202 to vibrate back and forth. This vibration can promote a more uniform distribution of the material on the screening basket. The material is distributed in a specific area to improve screening efficiency and avoid material accumulation in certain parts of the screen, which would lead to insufficient screening. After being screened by the first screening basket 203, the material falls into the second screening basket 204 for further screening. The screen mesh of the second screening basket 204 has a smaller aperture, which further refines the screening of the material. Smaller particles pass through the screen and fall into the third collection basket 205 at the bottom. The remaining material remains on the second screening basket 204. By opening the sliding door 207, the screened material can be easily removed, meeting the diverse needs of different application scenarios for the particle size of litchi fruitwood charcoal.
