Description

Technical Field

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

[0002] Straw is the plant stalk left after crop harvesting in agricultural production. It usually includes rice straw, wheat straw, corn straw, cotton straw, etc. It is an important by-product in agricultural production, but improper handling often leads to resource waste and environmental pollution. Straw crushing is an important part of straw processing. It involves using mechanical equipment to cut or crush straw into smaller particles or segments to facilitate subsequent processing and utilization. Crushed straw can be more easily stored, transported, burned, or used as raw material for feed and fertilizer. Although both chopped and segmented straw are forms of straw processing, they differ in their uses and functions. Existing straw processing crushers, due to the fixed spacing of their cutting components, can only process straw into segments or chopped pieces, making it inconvenient to adjust according to usage requirements. Therefore, we propose a straw processing crusher. Utility Model Content

When the fine crushing component is started, it processes the segmented straw produced by the coarse crushing component into small pieces. Furthermore, the fine crushing assembly includes crushing teeth 12, roller 13, filter screen 14, and electric lifting rod 15. The fine crushing box 4 is equipped with roller 13 inside, and the surface of roller 13 is equipped with equidistant crushing teeth 12. The fine crushing box 4 is equipped with filter screen 14 located below roller 13 inside, and the filter screen 14 is driven by electric lifting rod 15. Furthermore, the coarse crushing component includes crushing teeth 8 and roller shaft 9. The coarse crushing box 2 is provided with roller shaft 9, and the surface of roller shaft 9 is provided with equidistant crushing teeth 8. Furthermore, rollers 6 are installed at the outer ends of both roller shaft 1 9 and roller shaft 2 13. Roller shaft 2 13 is driven by motor 7 and connected to roller shaft 1 9 by belt drive. Furthermore, a discharge bin 3 is provided between the coarse crushing box 2 and the fine crushing box 4, and a guide plate 10 is movably connected inside the coarse crushing box 2, which is driven by a handwheel 11. The coarse crushing box 2 is equipped with a roller 9 with equidistant crushing teeth 8 inside. The motor 7 drives the roller 9 to rotate the crushing teeth 8, processing the straw into segments. The motor 7 also drives the roller 13 inside the fine crushing box 4 to rotate the crushing teeth 12, further processing the segmented straw into small pieces. The gap between the crushing teeth 12 is smaller than the gap between the crushing teeth 8. The electric lifting rod 15 inside the fine crushing box 4 drives the semi-circular filter screen 14 to rise and fall. The small pieces of straw smaller than the filter screen 14 are directly output through the filter screen 14, while the small pieces of straw larger than the filter screen 14 are pushed towards the rotating crushing teeth 12 for repeated crushing, ensuring the secondary processing and crushing effect of the straw. A discharge hopper 3 is provided between the coarse crushing box 2 and the fine crushing box 4. The discharge hopper 3 or the fine crushing box 4 is controlled by the baffle 10 at the inner end of the discharge hopper 3, which facilitates the selection of directly outputting segmented straw or outputting small pieces of straw after secondary processing, so as to realize the selection of the type of straw output according to the usage requirements.

[0016] Based on the aforementioned scheme, the drying assembly includes a baffle 5, a spiral roller 16, a fan blade 17, and a drive shaft 18. The drive shaft 18 is provided inside the drying chamber 1. The spiral roller 16 is mounted on the surface of the drive shaft 18. One end of the drive shaft 18 extends to the outside of the drying chamber 1, and the fan blade 17 is mounted on the surface of the drive shaft 18 outside the drying chamber 1. The outer end of the drive shaft 18 is connected to the roller shaft 9 via a roller 6 and a belt. The baffle 5 is detachably connected inside the drying chamber 1 below the spiral roller 16. As a further improvement of this invention, a PLC control panel is installed on the outside of the fine crushing box 4, and the PLC control panel is electrically connected to the motor 7 and the electric lifting rod 15. A drying chamber 1 with a spiral roller 16 and a fan blade 17 is set on top of the coarse crushing chamber 2. The motor 7 also drives the drive shaft 18 to rotate. The drive shaft 18 drives the spiral roller 16 and the fan blade 17 to rotate. On the one hand, the fan blade 17 rotates and blows air into the drying chamber 1 to dry the straw. On the other hand, heating wires can be set on the air inlet or air outlet side of the fan blade 17 to blow warm air into the drying chamber 1, which will improve the drying effect of the straw. On the other hand, the rotation of the spiral roller 16 stirs and separates the straw, which can better dry the straw and prevent the straw from affecting the crushing effect due to moisture. It also effectively prevents the straw from entering the coarse crushing chamber 2 and the fine crushing chamber 4 and causing rust.

[0017] It should be noted that this utility model is a straw crusher. First, open the top cover of the drying chamber, add the straw to be crushed into the drying chamber 1, and close the cover. Operate the PLC control panel to start the motor 7. The motor 7 drives the drive shaft 18 to rotate through the roller 6 and belt. The drive shaft 18 drives the spiral roller 16 and the fan blade 17 to rotate. On the one hand, the fan blade 17 rotates and blows air into the drying chamber 1 to dry the straw. On the other hand, the spiral roller 16 rotates to stir and separate the straw, which can better dry the straw. Then, according to the type of straw to be processed, turn the handwheel 11 to drive the guide plate 10 to rotate. When it is necessary to output segmented straw, turn the handwheel 11 so that the guide plate 10 blocks the top of the fine crushing chamber 4. Then pull out the baffle 5 to allow the straw inside the drying chamber 1 to pass through. The straw enters the coarse crushing box 2, where the motor 7 drives the roller 9 to rotate the crushing teeth 8, processing the straw into segments. The segments are then directly discharged through the discharge bin 3. When it is necessary to output clumps of straw, the handwheel 11 is turned so that the guide plate 10 blocks the top of the discharge bin 3. The straw inside the drying box 1 is first processed into segments by the rotating crushing teeth 8 in the coarse crushing box 2, and then enters the fine crushing box 4 where it is processed into clumps by the smaller-spaced crushing teeth 12. Clumps of straw smaller than the filter screen 14 are directly discharged through the filter screen 14, while clumps of straw larger than the filter screen 14 are pushed by the electric lifting rod 15 towards the rotating crushing teeth 12 for repeated crushing, ensuring the secondary processing and crushing effect of the straw. Finally, the clumps of straw are discharged through the bottom of the fine crushing box 4.
