Abstract
Herbicides, bush cutters and other tools are used for weed management in orchards and border areas on arable land. However, weed management involves heavy labor and thus it is necessary to develop a labor-saving sprayer for the efficient use of herbicides. So, a pulling herbicide sprayer was developed based on the wheel pump sprayer.
This sprayer has no engine, but operates the pump by rotation of a wheel. A nozzle has been built in a form spray nozzle for low volume (25L per 10a) and for coarser spray. The application rate of herbicides is linked with the application speed, so if operator walks at a speed of 2Kmper hour, the sprayer will work at a volume of 25L per 10a exactly. A built-in pressure relief valve prevents the sprayer from developing excessive pressure. Herbicides do not drift towards the operator since the operator moves ahead of the sprayer in the direction of the application.
This sprayer has a highly prospective value as a new model, low-volume herbicide sprayer.
