Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of laying hen breeding equipment, and particularly relates to a dustproof device for air exhaust of henhouse. BACKGROUND

[0002] At present, chicken farms are generally large industrialized plantations, and the chicken farms are generally built with bricks and concrete, which is convenient to obtain materials and can be combined with farmland to raise chickens and fertilize the field. In order to reduce the occurrence of chicken flu symptoms, it is necessary to ensure normal ventilation in a large area of the plant. The common ventilation method is generally a simple air extractor, which has a single function. Due to the large area of the chicken farm and the large number of chickens, the chicken feathers and chicken down dropped by the chickens are relatively more. If they are directly discharged through the air extractor, it will pollute the environment.

[0003] In order to solve the above problems, the existing means generally adds a filter screen on the air extractor to filter the chicken feathers. However, after a long time, the surface of the filter screen is blocked by chicken feathers. At this time, ventilation must be stopped, and the chicken feathers on the filter screen must be removed to continue normal work, which greatly increases the labor consumption. The chicken feathers adhered to the filter screen are not easy to collect, and secondary pollution is easy to occur. CONTENT OF THE UTILITY MODEL
