Summary of the invention:
Goal of the invention of the present utility model provides a kind of Backpack double-cylinder agricultural atomizer, the opplied moment when it can balanced hand lever moves up and down, and the merit that people have been done fully changes into the injection energy of liquid.
Backpack double-cylinder agricultural atomizer described in the utility model, comprise liquid reserve tank, syringe, pull bar, hand lever, vacuum cup, unidirectional liquid sucting valve, unidirectional liquid valve fluid switch, drain pipe, pipette, syringe is by the tubular pump housing, skin volume piston, piston rod is formed, the tubular pump housing is fixed on the end face of liquid reserve tank, skin volume piston is the lower end of piston rod regularly, and place in the tubular pump housing, it is characterized in that: described syringe has two, combination valve is fixed on the bottom of the tubular pump housing of two syringes hermetically, in combination valve, be provided with two unidirectional liquid sucting valves and two unidirectional liquid valves, two unidirectional liquid sucting valves communicate with the bottom of the two tubular pump housings respectively, link to each other with pipette after the other end parallel connection, the lower end of pipette reaches the bottom of liquid reserve tank; Two unidirectional liquid valve one ends communicate with the bottom of the two tubular pump housings respectively, link to each other with vacuum cup after the other end parallel connection, and vacuum cup is fixed on the liquid reserve tank; Fixedly connected with the upper end of piston rod respectively in the link rod plate two ends, hand lever is hinged and connected on the lower end side of liquid reserve tank by the rotating support pin, the lower end of pull bar and the ear seat on the hand lever are hinged, the upper end of pull bar is connected with the center hinge of link rod plate, drain pipe links to each other with vacuum cup by the fluid switch, right side at the rotating support pin of hand lever is provided with tension bracket, is provided with stretch cord between the low order end of hand lever and liquid reserve tank.
When hand lever upwards spurs, tension bracket struts stretch cord, the merit that people did is except finishing the required energy of imbibition, all the other then are stored in the elastic body, when hand lever is upwards moved extreme position to, stored energy maximum in the elastic thread, this moment, elastic thread forced hand lever to move down work done, will reduce the downward thrust of people like this, help the balanced hand lever downward active force that makes progress, the energy that can will be stored in the stretch cord changes into effective liquid jet power simultaneously, through the existing downward thrust of agricultural atomizer of test, can drive two syringe operations, this double-cylinder agricultural atomizer is the force balance during operation up and down not only, and efficient is higher.
