Technical Field

[0001] The utility model relates to the field of straw shredding devices, in particular to a straw shredding device for making straw blankets. Background Art

[0002] Straw-based blanketing, as an environmentally friendly and resource-recycling technology, has garnered widespread attention in recent years. As agricultural waste, straw is often burned or discarded, wasting resources and potentially polluting the environment. With the growing adoption of sustainable development, researchers are exploring ways to effectively transform this waste into high-value-added products. Straw-based blanketing is one such innovative application. By processing straw into filaments or fibers, and then weaving them into blankets through a specialized process, it not only addresses the straw disposal issue but also develops new biomass products.

[0003] In the prior art, straw shredding devices are intended to efficiently and evenly cut straw raw materials into fibers of suitable length and shape for subsequent weaving or compression molding.

[0004] However, the traditional straw shredding device lacks a straw positioning mechanism. During the straw shredding operation, the straw is easily offset, thereby affecting the shredding progress. Therefore, the present invention proposes a straw shredding device for straw blanket making to solve the above problems. Utility Model Content

At the same time, the several protrusions 18 provided can increase the friction between the straw and the block block 17, providing guidance for the movement of the straw.

At the same time, the several protrusions 18 set can increase the friction between the straw and the block block 17, providing guidance for the movement of the straw. This avoids the problem that the traditional straw shredding device lacks a positioning mechanism for the straw, and the straw is easily offset during the straw shredding operation, thereby affecting the shredding progress.
