Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer production technology, specifically relating to a biological organic fertilizer block crushing device. Background Technology

[0002] After fermentation, organic fertilizer is in a lumpy state and needs to be crushed. This requires an organic fertilizer crushing device. Most existing organic fertilizer lumps crushing devices use a pair of crushing rollers to apply pressure to the organic fertilizer. While this achieves overall crushing, the pressure from the rollers causes localized high-density small lumps to form, resulting in uneven and loose crushed fertilizer. These small lumps increase the difficulty of granulation, leading to unevenly sized organic fertilizer particles, which affects the use of the fertilizer and plant growth. Therefore, we propose a bio-organic fertilizer lump crushing device that ensures uniform crushing and loose organic fertilizer. Summary of the Invention

[0003] To overcome the problem in the prior art where crushing organic fertilizer by applying pressure with rollers achieves overall pulverization, but localized high-density small lumps form under pressure, resulting in uneven and loose pulverized organic fertilizer, this invention provides a biological organic fertilizer block pulverizing device. In this invention, both the pulverizing roller 3 and the dispersing roller 8 employ a single-roller dispersing method, avoiding the problem of localized high-density particle formation caused by roller compression, ensuring the organic fertilizer is loose. The organic fertilizer is then sieved by the screening roller 5, ensuring effective granulation and facilitating subsequent granulation and plant growth.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A biological organic fertilizer block crushing device mainly includes a frame 1, a crushing tank 2, a crushing roller 3, a crushing motor 4, a screening roller 5, a rotary support disc 6, a gear disc 61, a screening motor 62, a feed trough 7, a dispersing roller 8, and a dispersing motor 9.

The feed chute 7 is installed on the side of the crushing tank 2, and the end of the feed chute 7 extends into the screening roller 5. The dispersing roller 8 is installed horizontally inside the feed chute 7. The dispersing motor 9 is installed on the side of the feed chute 7 and is connected to the dispersing motor 9 via transmission. The bottom of the crushing tank 2 is provided with a discharge port 21.

[0005] Furthermore, the screening drum 5 is provided with screening holes evenly, and the screening drum 5 is provided with material handling plates 51 evenly inside.

[0006] Furthermore, the crushing roller 3 includes a rotating shaft 31 and crushing teeth 32. The rotating shaft 31 is installed inside the crushing tank 2 through bearings, and the crushing teeth 32 are evenly installed on the rotating shaft 31.

[0007] Furthermore, the crushing teeth 32 are L-shaped with their ends bent to improve crushing efficiency.

[0008] Furthermore, the dispersing roller 8 includes a roller shaft 81 and dispersing teeth 82. The dispersing teeth 82 are evenly installed on the roller shaft 81. To improve the dispersing efficiency, the ends of the dispersing teeth 82 are bent to form L-shaped dispersing teeth.

[0009] Furthermore, to improve the dispersing effect, the feed trough 7 is equipped with a dispersing chamber 71 that matches the dispersing roller 8.

[0010] Furthermore, the feed trough 7 is provided with a feed hopper 72 for easy receiving and feeding of materials.

The crushing tank 2 is mounted on the frame 1, the crushing roller 3 is horizontally mounted inside the crushing tank 2 via bearings, the crushing motor 4 is mounted on the outside of the crushing tank 2, and the crushing roller 3 is connected to the crushing motor 4 via a transmission. The screening drum... 5 is rotatably installed inside the crushing tank 2 via a rotary support plate 6. The crushing roller 3 is located inside the screening roller 5. The gear plate 61 is fixed on the screening roller 5. The screening motor 62 is installed inside the crushing tank 2 and is connected to the gear plate 61 via gear transmission. The feed chute 7 is installed on the side of the crushing tank 2, and the end of the feed chute 7 extends into the screening roller 5. The dispersing roller 8 is installed laterally inside the feed chute 7. The dispersing motor 9 is installed on the side of the feed chute 7 and is connected to the dispersing motor 9 via transmission. The bottom of the crushing tank 2 is provided with a discharge port 21. The organic fertilizer to be crushed is conveyed into the feed trough 7 by the material elevator. After the larger pieces of organic fertilizer are initially crushed by the dispersing roller 8, they enter the screening roller 5. As the screening roller 5 rotates, the organic fertilizer is screened. Organic fertilizer that does not meet the requirements is crushed by the crushing roller 3. In this utility model, both the crushing roller 3 and the dispersing roller 8 adopt a single roller dispersing method to avoid the problem of local organic fertilizer forming high-density particles caused by the compression of rollers, and to ensure that the organic fertilizer is loose. The organic fertilizer is screened by the screening roller 5 to ensure the crushing effect of organic fertilizer particles, which is beneficial to the subsequent granulation and plant growth.

[0019] The screening drum 5 is uniformly provided with screening holes, and the screening drum 5 is uniformly provided with a material handling plate 51. The organic fertilizer is screened by the screening drum 5. The organic fertilizer that meets the requirements is discharged from the discharge port 21 through the screening holes and is transported by the conveyor belt for packaging. The lumpy organic fertilizer that does not meet the requirements is lifted and thrown out as the material handling plate 51 rotates. During the falling process, the lumpy organic fertilizer is broken up and crushed by the high-speed rotating crushing roller 3. In order to ensure crushing efficiency, the crushing roller 3 rotates in the same direction as the screening drum 5.

[0020] The crushing roller 3 includes a rotating shaft 31 and crushing teeth 32. The rotating shaft 31 is installed in the crushing tank 2 through bearings. The crushing teeth 32 are evenly installed on the rotating shaft 31. The crushing and pulverizing are carried out by the crushing teeth 32, which will not compress the organic fertilizer and can ensure that the organic fertilizer is loose.

[0021] The aforementioned crushing teeth 32 are L-shaped with their ends bent to improve crushing efficiency.

[0022] The dispersing roller 8 includes a roller shaft 81 and dispersing teeth 82. The dispersing teeth 82 are evenly installed on the roller shaft 81. To improve the dispersing efficiency, the ends of the dispersing teeth 82 are bent to form L-shaped dispersing teeth.

[0023] To improve the dispersing effect, the feed trough 7 is equipped with a dispersing chamber 71 that matches the dispersing roller 8.

[0024] The feed trough 7 is equipped with a feed hopper 72 for easy receiving and feeding of materials.

[0025] Work process: The organic fertilizer to be crushed is conveyed into the feed trough 7 by the material elevator. After the larger pieces of organic fertilizer are initially crushed by the dispersing roller 8, they enter the screening roller 5. As the screening roller 5 rotates, the organic fertilizer is screened. Organic fertilizer that meets the requirements is discharged from the discharge port 21 through the screening holes and is then conveyed and packaged by the conveyor belt. The lumpy organic fertilizer that does not meet the requirements is lifted and thrown out as the material handling plate 51 rotates. During the fall, the lumpy organic fertilizer is further dispersed and crushed by the high-speed rotating crushing roller 3. In order to ensure crushing efficiency, the crushing roller 3 and the screening roller 5 rotate in the same direction. In this utility model, both the crushing roller 3 and the dispersing roller 8 adopt the single roller dispersing method to avoid the problem of local organic fertilizer forming high-density particles caused by the compression of rollers, and ensure that the organic fertilizer is loose. The screening of organic fertilizer by the screening roller 5 ensures the crushing effect of organic fertilizer particles, which is beneficial to the subsequent granulation and plant growth.
