Covering equipment for agricultural products

摘要

The equipment is particularly for farm and garden products during cultivation, having a three-dimensional frame typically of profiled aluminium members covered by translucent glass or plastics. Two or more of the frame members (18) are fixed at their bottom ends to the weights (14), which typically consist of troughs filled with rainwater running off the covers. The troughs can be of metal gauze lined on the inside with waterproof sheet. Where plastics sheet held taut over the members is used as the covering material, its lowermost edges can be above troughs, and it can be unrolled over the members.
