Abstract

A knapsack dual-cylinder agricultural sprayer comprises two manual piston pumps, a push-pull rod, a manual rod, a vacuum cup and a combination valve, wherein the two manual piston pumps are respectively composed of a cylindrical pump body, a leather roll piston and a piston rod, the combination valve is hermetically fixed at the bottom of the two manual piston pumps, two one-way liquid suction valves connected in parallel and two one-way liquid outlet valves connected in parallel are arranged in the combination valve, the one-way liquid suction valves are connected in parallel and then connected with a liquid suction pipe, the one-way liquid outlet valves are connected in parallel and then connected with the vacuum cup, a tension frame is arranged on the manual rod, and an elastic rope is arranged between the rightmost end of the manual rod and a liquid storage tank. When the manual rod is pulled upwards, the tension bracket props up the elastic rope, redundant energy is stored in the elastic body, when the manual rod is pulled upwards to a limit position, the energy stored in the elastic line is maximum, at the moment, the elastic line forces the manual rod to move downwards to do work, therefore, the downward thrust of people can be reduced, the upward and downward acting forces of the manual rod can be balanced, the operation is more balanced, and the liquid outlet efficiency is high.

Description

Technical field:

The utility model relates to a kind of agricultural equipment, relates in particular to agricultural atomizer.

Background technology:

Agricultural atomizer is very extensive in application in agriculture, is one of main hand-operated tools of prevention and elimination of disease and pests, also is the manual utensil that carries out meticulous pouring in the economic plants plantation.Existing agricultural atomizer comprises liquid reserve tank, a syringe, pull bar, hand lever, vacuum cup, hydrojet switch and drain pipe, syringe is by the tubular pump housing, skin volume piston, piston rod, unidirectional liquid sucting valve, pipette is formed, the tubular pump housing is fixed on the end face of liquid reserve tank, skin volume piston is fixed on the lower end of piston rod, and place in the tubular pump housing, be provided with unidirectional liquid sucting valve and unidirectional liquid valve in the bottom of the tubular pump housing, pipette links to each other with unidirectional liquid sucting valve, its lower end extends the bottom of liquid reserve tank, unidirectional liquid valve links to each other with vacuum cup, vacuum cup is fixed on the liquid reserve tank, drain pipe links to each other with vacuum cup by the fluid switch, hand lever is hinged on the lower end side of liquid reserve tank by fulcrum post, the lower end and the hand lever of pull bar are hinged, the upper end of pull bar and the upper end of piston are hinged, when hand lever upwards draws, the apron piston moves up, syringe is in the imbibition state, when hand lever is passed downwards, the apron piston moves down, syringe is in pressure and goes out liquid status, people could be made injection energy that merit be converted into liquid when having only hand lever to push downwards, when hand lever upwards draws, the merit that people have done does not make full use of, people are when operation, upwards draw and to the active force inequality that presses down, especially bigger to the resistance that presses down, this agricultural atomizer structure imperfection, it is not high to do diligent utilization, and benefit is lower.

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.
