Technical Field

[0001] This utility model relates to the field of straw crushing technology, specifically a straw crushing device. Background Technology

[0002] Straw, as a waste product in agricultural production, is traditionally treated mainly by burning, piling, or simple composting.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A straw crushing device includes a conveyor belt 1 and a crushing box 2. The crushing box 2 is installed on one side of the conveyor belt 1. Support legs 3 are fixedly installed on the lower side of the supports on both sides of the conveyor belt 1. Straw fixing structures 4 are installed on the upper side of the supports on both sides of the conveyor belt 1. The straw fixing structure 4 includes a fixing belt 41. Support rollers 42 are rotatably mounted at both ends of the fixing belt 41. Fixing frames 43 are installed on both sides of the support rollers 42 via rotating shafts. One side of the fixing frame 43 is installed on the supports on both sides of the conveyor belt 1 via a vertical rod 46. A pressing structure 44 is installed on the lower side of the fixing frame 43. The upper side of the fixing frame 43 is equipped with a tensioning structure 45. The straw crushing device of the present invention improves the conveying and crushing efficiency of straw through the structure of the conveyor belt 1 and the crushing box 2. The straw fixing structure 4, through the cooperation of the fixing belt 41 and the support roller 42, can effectively fix the straw during the conveying process and prevent it from slipping on the conveyor belt. In particular, the pressing structure 44 and the tensioning structure 45 equipped with the fixing frame 43 can ensure the tension and stability of the fixing belt, thereby ensuring the smooth transmission of straw in the whole crushing process and improving the overall operating efficiency.

[0023] The inner side of the crushing box 2 is sequentially equipped with a first crushing structure, a second crushing structure, and a collection box 21 from top to bottom. A feed inlet 22 is provided on one side of the crushing box 2, and the first crushing structure is installed on one side of the feed inlet 22. The second crushing structure is installed below the first crushing structure, and the collection box 21 is installed below the second crushing structure. The collection box 21 is slidably installed on the inner side of the bottom end of the crushing box 2. By sequentially arranging the first crushing structure, the second crushing structure, and the collection box 21 inside the crushing box 2, staged crushing and efficient collection of straw are achieved. The second crushing structure allows the straw to undergo further fine crushing after primary crushing, thereby reducing crushing time and improving work efficiency. The first crushing structure includes a drive motor 23 and multiple crushing blades 24, which are distributed in a matrix on the outer side of the main shaft of the drive motor 23. The outer side of the drive motor 23 is installed on the inner side of the top of the crushing box 2 via a connecting bracket 25. The crushing structure combines multiple matrix-arranged crushing blades 24 with a drive motor 23 to ensure efficient cutting and crushing of straw. The second crushing structure includes crushing rollers 26 arranged symmetrically on both sides. The crushing rollers 26 are rotatably mounted on the inner side of the crushing box 2 via a horizontal shaft 27, and a drive structure is installed at one end of the horizontal shaft 27. The second crushing structure performs secondary crushing through the symmetrically arranged crushing rollers 26. This design makes full use of the symmetrical structure to improve the crushing effect and equipment stability. The pressing structure 44 includes a pressing shaft 441. The outer side of the pressing shaft 441 is in contact with the fixing belt 41. Both ends of the pressing shaft 441 are rotatably equipped with pressing plates 442. A pressing slide rod 443 slides on one side of all pressing plates 442, and the other side of the pressing slide rod 443 is installed on one side of the fixing frame 43. A pressing spring 444 is installed on the outer side of the pressing slide rod 443. This arrangement allows the straw to be better fixed during the conveying process, preventing the material from loosening or falling off. The cooperation between the clamping shaft 441 and the clamping plate 442 ensures a uniform distribution of clamping force, while the clamping slide rod 443 and the clamping spring 444 provide more precise tension control, making the entire conveying process more stable and reliable. The tensioning structure 45 includes a tensioning shaft 451, the outer side of which is in contact with the fixing belt 41. Both ends of the tensioning shaft 451 are rotated with tensioning plates 452. A tensioning slide rod 453 slides on one side of all tensioning plates 452, and the other side of the tensioning slide rod 453 is installed on one side of the fixing frame 43. A tensioning spring 454 is installed on the outer side of the tensioning slide rod 453. The tensioning structure 45 adjusts the tension of the fixing belt 41 through the tensioning shaft 451 and the tensioning plate 452, ensuring the stability of the equipment during long-term operation. The tension of the fixing belt can be effectively adjusted by the sliding tensioning slide rod 453 and the tensioning spring 454, so that the equipment can maintain optimal operating performance under different working conditions.

[0024] Workflow: First, the straw to be crushed is fed into the feed inlet 22 of the equipment via conveyor belt 1. During the conveying process, the straw passes through the straw fixing structure 4 installed on one side of the conveyor belt. This structure consists of a fixing belt 41, a support roller 42, and a fixing frame 43. The fixing belt 41 rotates through the support roller 42, driving the straw to be fixed on the conveyor belt 1 to prevent material slippage. The fixing frame 43 is fixed to the support of the conveyor belt 1 by vertical rods 46, ensuring that the straw remains stable during the conveying process. To enhance the tension of the fixing belt, the fixing frame 43 is equipped with a pressing structure 44 and a tensioning structure 45. The pressing structure 44 consists of a pressing shaft 441 and a pressing plate 442. The pressing plates 442, which rotate at both ends of the pressing shaft 441, cooperate with the pressing spring 444 through the pressing slide rod 443 to maintain the appropriate tension of the fixing belt 41, while also effectively fixing the straw. The tensioning structure 45 is connected to the tensioning shaft 45 through the tensioning shaft 45. 1. The tensioning plate 452 further tensions the fixing belt 41, ensuring that the fixing belt 41 always maintains appropriate tightness and effectively preventing the straw from loosening or slipping during the conveying process. Then, the fixed straw enters the crushing box 2 and is introduced into the interior through the feed port 22. The first crushing structure inside the crushing box 2 consists of a drive motor 23 and multiple crushing blades 24. The drive motor 23 drives the crushing blades 24 to rotate at high speed through the main shaft, performing preliminary cutting and crushing of the straw. The matrix arrangement of the blades ensures the uniformity of crushing. The crushed straw enters the second crushing structure, which consists of symmetrically arranged crushing rollers 26. The crushing rollers 26 rotate through the horizontal shaft 27 to further finely crush the straw. After these two stages of crushing, the straw fragments enter the collection box 21 at the bottom of the crushing box 2. The collection box 21 is installed in the crushing box through a sliding device, which can smoothly collect and discharge the crushed straw fragments.

[0025] After the work is completed, all components of the equipment remain in stable operation, ensuring the straw crushing efficiency and the overall reliability of the device. The pressing and tensioning structures not only ensure the stability of the conveyor belt but also provide continuous tension during the crushing process, preventing material slippage or loosening. Through this efficient and stable workflow, the straw crushing device of this invention can improve production efficiency and reduce energy waste while ensuring crushing quality. Furthermore, the high degree of automation greatly simplifies the operation process and enhances the convenience and efficiency of overall production.
