Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw cutting technology, and in particular to a straw cutting device for straw processing. Background Technology
[0002] Straw is a versatile and renewable biological resource. Processing straw requires the use of straw cutting motors. Existing straw cutting motors typically involve directly feeding bundled straw into the machine for cutting. The cut straw can then be processed into feed, fuel, or fiberboard. To accommodate different uses of the straw segments, the cutting motor needs to cut them into segments of varying lengths. Current cutting methods often rely on manual cutting, which is inefficient. Alternatively, cutting devices may use settings, but these lack the ability to cut straw to a fixed length, requiring manual adjustment during the process, further reducing cutting efficiency. Therefore, we propose a straw cutting device for processing. Utility Model Content
