Description

TECHNICAL FIELD

[0001] The utility model relates to walnut production and processing technical field, concretely relates to a kind of buffering noise reduction components for walnut production and processing workshop conveying belt feed inlet. BACKGROUND

[0002] In walnut production and processing workshop, the conveying and processing of walnut is a crucial link. Because of its hard shell and irregular shape, when walnut is transported on the conveying belt, the collision between walnut and walnut, and between walnut and conveying belt feed inlet becomes a significant problem. This collision not only produces loud noise, affecting the hearing health of workers and the comfort of the working environment, but also may have some impact on the continuity and stability of the production line, reducing production efficiency.

[0003] The existing technology of walnut production and processing workshop conveying belt feed inlet design has obvious shortcomings in solving the above problems: first, in terms of noise control, the existing feed inlet design lacks effective noise reduction measures. The direct collision between walnuts and the impact of walnuts on the feed inlet will produce sharp and continuous noise. This noise not only disrupts the normal production order of the workshop, but also has irreversible impact on the hearing health of workers in the long run. Second, the existing feed inlet design also has some shortcomings in preventing walnuts from leaving the conveying belt due to collision. Although not all walnuts will jump out, the lack of effective buffering and guiding structure of the feed inlet may still cause some walnuts to deviate from the conveying belt path during transmission due to improper collision force, resulting in material scattering and waste, affecting the continuity and stability of the production line.

[0004] In summary, the existing technology of walnut production and processing workshop conveying belt feed inlet design has obvious shortcomings in noise control, preventing walnuts from leaving the conveying belt due to collision, flexibility and adaptability, and maintenance. Therefore, it is necessary to design a new type of buffering noise reduction component, which aims to effectively solve the noise problem caused by the collision between walnuts, while reducing the situation of walnuts leaving the conveying belt due to improper collision force, improving the continuity and stability of the production line, and thus improving the production efficiency and working environment quality of walnut production and processing workshop.
