Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of debris removal devices, in particular to a debris removal device of a field returning machine. Background Art
[0002] In agricultural production, straw return to the field, a key means of increasing soil organic matter and promoting sustainable agricultural development, faces numerous challenges during winter operations. Straw removal is particularly complex due to its high moisture content, hard texture, and tendency to freeze. Design limitations often hinder the scattering of straw during winter operation, resulting in low screening efficiency and cumbersome operation. This not only affects the cleanliness of the work environment but also poses a potential threat to the health of workers.
[0003] Specifically, the traditional debris removal device of the straw returner lacks an effective sealing mechanism in the feeding process, which makes the straw easily scattered due to wind or mechanical vibration during the feeding process. This not only increases the difficulty of subsequent cleaning, but also may cause environmental pollution and affect the cleanliness of the working area. At the same time, in the screening stage, most traditional devices adopt a static screening structure, which is difficult to effectively separate large pieces of debris in the straw, resulting in low screening efficiency and easy clogging of the screen holes, affecting the normal operation and screening effect of the equipment. Therefore, in response to the above technical problems, a debris removal device for the straw returner is proposed. Utility Model Content
