[0034] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0035] Straw shredder, refer to Figure 1-10 ,include

[0036] The frame 1, as the main support of the entire equipment, provides a stable foundation for the installation of other components and ensures the stability of the equipment during operation. Its structural strength has been optimized and can withstand various forces generated during the shredding process.

[0037] The feeding hopper 2, driven by a motor and gear pair, is located above the frame 1. The feeding hopper 2 can push the straw above the shredding assembly 3 described below.

[0038] The shredding assembly 3 is fixedly installed on the frame 1 and located between the feeding hoppers 2;

[0039] Two guide plates 4 are mounted on the frame 1 and are symmetrically arranged about the top opening of the shredding assembly 3 to guide the straw. The guide plates 4 are rotatably connected to the top of the frame 1, and their rotation direction is perpendicular to the length direction of the opening of the blade box 31. A stud 41 is threaded on the frame 1, and the top of the stud 41 abuts against the bottom of the guide plate 4. By adjusting the extension and retraction of the stud 41 in the vertical direction, the height of the guide plate 4 can be precisely changed, thereby adapting to straw materials of different thicknesses and flow rates, ensuring that the straw can fall accurately into the shredding assembly 3, and improving the accuracy and efficiency of shredding processing.

[0040] The transport pipe 5 is connected to the blower 6. The transport pipe 5 is connected to the cutter box 31. The blower 6, which provides power for material conveying, is also connected to the side of the transport pipe 5. After the material is shredded, it is quickly transported to the designated collection position through the transport pipe 5 under the action of the airflow generated by the blower 6, which avoids the material from accumulating in the cutter box 31 and ensures the continuous and efficient operation of the equipment. It also facilitates the subsequent centralized processing, packaging or further processing of the processed straw material.

[0041] The shredding assembly 3 includes a turntable fixed to the blade box 31 and driven by a motor. Multiple sets of main blades 33 are evenly spaced on the side of the turntable, with equal intervals between blades within the same set. This layout ensures that the straw is cut without blind spots during high-speed rotation of the turntable, achieving all-around shredding. One end of the uppermost main blade 33 extends into the feeding hopper 2, allowing for initial cutting of the straw as soon as it enters the shredding area, making the material easier for subsequent fine processing.

[0042] The inner side of the tool box 31 has multiple alternating rough-surfaced bottom cutters 37 and smooth-surfaced bottom cutters 38 along the rotation direction of the turntable. These are used in conjunction with the end of the main cutter 33. When the end of the main cutter 33 is aligned with the smooth-surfaced bottom cutter 38 or the rough-surfaced bottom cutter 37, the main cutter 33 is perpendicular to the smooth-surfaced bottom cutter 38 or the rough-surfaced bottom cutter 37, resulting in a relatively stable structure.

[0043] The smooth bottom blade 38 and the rough bottom blade 37 are set as cuboids. The side of the rough bottom blade 37 facing the main blade 33 and the opposite side of that side are serrated. When interacting with the main blade 33, it can both tear the straw fibers with the serrations and assist in cutting with the smooth surface of the smooth bottom blade 38, making the straw shredding more delicate and uniform. After a period of use, it is also convenient to disassemble and change the direction for continued use.

[0044] The opening of the blade box 31 is provided with multiple cutters 35. The cutters 35 are used in conjunction with the end of the main blade 33. The cutters 35 are set in the shape of a regular square pyramid counter, and the cutters 35 extend from bottom to top, which can make effective contact, gather the straw, improve the extrusion effect, and make the material more refined.

[0045] The adjacent inner side of the blade box 31 is also fixedly installed with a side blade 39 that works in conjunction with the side of the main blade 33. The side blade 39 consists of a vertical plate parallel to the main blade 33 and a horizontally arranged cuboid bar. The bar works in conjunction with the main blade 33 to cut the straw laterally, preventing the straw from getting tangled or stuck during the shredding process, and ensuring the smooth operation of the shredding process.

[0046] The rotating shaft on the turntable is fixedly connected to the side of the tool box 31 by bolts through the bearing seat 32. The top of the tool box 31 is provided with a vertical groove 36 for the vertical insertion of the rotating shaft. A baffle 34 is fixedly installed on the vertical groove 36 by bolts. This structure not only ensures the stability of the turntable rotation, but also facilitates installation, disassembly and maintenance. When the turntable or main blade 33 and other parts need to be replaced or repaired, the operator can operate quickly and reduce equipment downtime.

[0047] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
