Description

Power spraye

The utility model relates to sprayer, particularly relates to agricultural and goes up the prevention and elimination of disease and pests sprayer.

Agroatomizer is with its induced way difference, can be divided into power driven sprayer and sprayer manually.Manual sprayer is generally Backpack type, uses relatively flexibly, convenient, and cost is also lower, but that its greatest drawback is a labor intensity of operating staff is very big, and the weight of will load on the one hand utensil and soup, one side need again constantly drive force pump with hand; Inefficiency, speed are slow, and pressure is limited, and jet length is near; Cause the pollution of agricultural chemicals easily, be harmful to health human body.And existing power driven sprayer, as internal combustion engine sprayer and power spraye, internal combustion engine sprayer power is big, and speed is fast, is applicable to large tracts of land area use in flakes, the general normal several people's operation that needs.So-called power spraye is by the driven by motor pump, and its prior art is that the structure of structure more complicated, especially pump is unreasonable, and is fragile, therefore, do not apply.

The purpose of this utility model is that design is a kind of by storage battery power supply, and pump structure is simple, and is in light weight, power spraye easy to use.

The technical scheme of the utility model power spraye is: be made up of institutes such as force pump, pipette, drain pipe and air chamber jars, electromotor is by storage battery power supply, electromotor is by the transmission mechanism drivening rod, connecting rod drives the piston in the cylinder sleeve, the end cap of cylinder sleeve connects pipette and drain pipe, in pipette and the drain pipe one-way cock is arranged, connect the air chamber jar on the drain pipe.

Power spraye of the present utility model connects protection switch on drain pipe, protection switch is linked through microswitch and relay by push rod.

Power spraye of the present utility model, its so-called transmission mechanism is to drive eccentric wheel after the gear graduation, the eccentric wheel drivening rod.

Power spraye of the present utility model, its piston are that copper or aluminium or plastic material are made, and sealing ring is arranged on the piston.

Power spraye of the present utility model, the sealing ring on its piston are that the Polyurethane material is made or elastomeric material is made.

The utility model discloses a kind of power spraye, by accumulator electromotor is powered, force pump is made up of connecting rod, piston, cylinder sleeve, and is simple in structure, the operating pressure height, and it is even to spray soup, and distance especially is fit to tall and big fruit tree and sprays; One man operation during use, soup and pump are placed on the ground, the back of the body of not choosing, laborsaving saving time, and reduce the pollution of agricultural chemicals to human body.

Fig. 2 is the utility model power spraye drain pipe direction structure schematic diagram;

Fig. 3 is that the utility model power spraye is overlooked direction cylinder sleeve, piston cutaway view;

Fig. 4 is the utility model power spraye circuit diagram.

Below in conjunction with Fig. 1-Fig. 4 embodiment of the present utility model is done detailed explanation.

1, electromotor; 2, speed-changing gear box; 3, fixed connecting piece; 4, microswitch; 5, push rod; 6, air chamber jar; 7, drain pipe; 8, cylinder sleeve end cap; 9, cylinder sleeve; 10, pull bar; 11, pipette; 12, connecting rod; 13, pin; 14, eccentric wheel; 15, the contact of microswitch; 16, casing; 17, sealing ring; 18, piston; 19, sealing ring; 20, relay; 21, fuse; 22, accumulator; 23, switch; 24, potentiometer.

The utility model relates to power spraye, be installed in the casing 16 by motor-operated pump and accumulator 22, electromotor 1 is by accumulator 22 power supplies, accumulator 22 is selected the 6-12 volt for use, motor speed is after speed-changing gear box 2 slows down, connect eccentric wheel 14, eccentric wheel is linked to each other with connecting rod 12 by pin 13, connecting rod drives piston 18, and sealing ring 19 is arranged on the piston, 17, sealing ring 19,17 are made by the Polyurethane material, perhaps sealing ring 19 adopts the Polyurethane material to make, sealing ring 17 is made by rubber, and anti-wear performance is good, and piston 18 is selected corrosion resistant non-ferrous metal copper for use, aluminium or plastics are made.Piston matches with cylinder sleeve 9, and cylinder sleeve can select for use stainless steel or stainless iron or plastic material to make, and cylinder sleeve etc. are linked to be integral body by fixed connecting piece 3 and gearbox 2 grades, and connector 3 can be open or closed, and pull bar 10 is arranged.Connect pipette 11 and drain pipe 7 on the end cap 8 of cylinder sleeve, in pipette and the drain pipe one-way cock is arranged.Connect air chamber jar 6 and protection switch annex in the drain pipe simultaneously, when obstructions such as mister head, output pressure increases; promote the push rod 5 of protection switch; push rod 5 is run into the contact 15 of microswitch 4, and microswitch is through relay 20 action, makes the electromotor shutdown of cutting off the power supply automatically.Potentiometer 24 is installed in circuit, is played the pressure regulation effect.
