Development of rail-mounted multifunctional spraying equipment for facility vegetables
Most of the spraying operations in domestic facility agriculture are now done by manual or electric backpack sprayers,but there are drawbacks such as low pesticide utilization,human injury and pollution of the environment.A track-mounted multifunctional spraying equipment for facility vegetables was designed and developed,which was moved by a track that can be fixed on the top,ground,and side of the greenhouse,and had a stabilizing mechanism,a lifting platform,a preheating system,and other expanding mechanisms.The results showed that the coverage of liquid and powder was 65.31%and 67.12%,respectively,which was significantly higher than that of knapsack spraying equipment(36.52%and 47.71%).Under the premise of the same box volume,the operation time of the spraying equipment was 23.87%less than that of the knapsack sprayer.After 7 days of application,the average effectiveness of the equipment was 90.47%,which was significantly higher than that of the knapsack sprayer(84.31%).This showed that the track-mounted multifunctional spraying equipment for facility vegetables had a wide spraying range,high stability,and enhances the effectiveness of the drug.This equipment could be widely used in the spraying operation of facility vegetables.
