ELECTRICALLY-DRIVEN PORTABLE SPRAYER Russian patent published in 2008 - IPC A01M7/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to small-sized portable devices for processing fruit trees, berry bushes, vegetables from wreckers, and also optimum dosed out irrigation with application of fertilizers. The sprayer consists of the portable tank for working liquid with a demountable cover and vertically-arranged electrically-driven submerged pump accommodated therein which serves for pumping over a liquid solution upwards. The tank has, in its lower central part, a bottom deepening above which the suck-in device of the submerged the pump is arranged including hose devices of discharging liquid solution from the pressure chamber of the said pump, devices of dispersion and electrical control of the sprayer. The electrically-driven pump for pumping over the liquid is a vibration type above the tension spring mounted on the shaft of the basic device which contains a bottom tubular part, a central basic part laying on the top surface of the demountable cover hollow, and two basic racks with holes for installation of the axles located in the top part of the basic device. The demountable cover has the central adjusting hole into which the basic device is inserted by the bottom tubular part accommodating the vibration electrically-driven pump. The axle is arranged in holes of lateral basic racks to adjust the position of the said vibration pump in height relative to bottom deepening. The liquid comes under pressure from a delivery tube of the vibration pump through the union fitted on a delivery tube of the said pump, to the liquid pressure regulator connected by means of demountable hose devices with snap-up connections with the sprayer demountable devices and electrically-driven pump control device. The demountable device of dispersion and electrical control consists from a rod of a certain length, mainly wooden, the hose with inlet and outlet unions with connections for feeding liquid solution to spraying head fixed on the outlet union being attached thereto. The demountable device of cut in/cut out the electrically-driven pump, fixed on the said rod, consists of a sealed interrupter switch and sealed plug.

EFFECT: simplification of processing the gardens, simpler design of sprayer.
