Controllable spraying device

Abstract

The invention discloses a controllable spraying device which comprises a water tank, a direct current water pump, a connecting water pipe, a rotating water pipe, a needle cylinder type piston, a spray head, a rotating drive device, a drive circuit and a controller. The voltage of the direct current water pump is controlled by using a preset spraying distance to ensure that water sprayed out of the spray head only covers the preset range. By depending on the control of a singlechip, the regularization of a water spraying track is intelligently completed, the function of whole water spraying isautomatically completed, thus the effects of fully efficiently utilizing water resources and saving water as well as protecting the environment are achieved. The invention can meet the requirement for spraying water drops on various fields of gardens, greenbelts, vegetables and fruits, agriculture and the like. If the spraying liquids are changed into pesticides, paints, anticorrosive paints and the like, the controllable spraying device can carry out the spraying. Irrigation requirements on different use areas can be met through the combination of a plurality of spray heads. Various shapes such as square, triangle, regular hexagon and the like can be obtained through spraying.

Description

technical field [0001] The invention relates to a spraying device, in particular to a controllable spraying device. Background technique [0002] At present, the sprinkling track of the spraying device used in our life is usually spiral, while the grass is generally rectangular, which makes it difficult to avoid the embarrassment of sprinkling the grass area during the sprinkling process, which brings inconvenience to pedestrians; Especially for lawn areas close to traffic arteries, the water spilled on the grass can easily lead to wet and slippery road surfaces, and even bring unnecessary traffic hazards. On the other hand, the inconsistency between the spraying trajectory and the shape of the grassland also makes it difficult to completely cover the entire lawn during the watering process, or repeatedly water some areas, making it difficult to achieve efficient grassland irrigation , the sprinkling effect is not ideal. More importantly, the water that spills over the law...

Problems solved by technology

The disadvantage is that the position of the water outlet and the angle of the water outlet are fixed, and the formation of the landscape pattern is formed through the cooperation of multiple water outlet points, that is to say, the landscape pattern is fixed and has certain limitations. The cross-section of the water outlet is large, resulting in the concentration of water at the point where the water falls, making it difficult to control its uniform spraying
