The lower part of the cylinder body is provided with a liquid charging valve and a liquid discharging valve, a liquid discharging valve port is connected with a flow guiding pipe to the bottom of the air chamber pot, an infusion pipe is installed in the air chamber, and the infusion pipe is connected with the liquid spraying pipe. The pump component of the sprayer has the characteristics of labor-saving process, corrosion resistance, low cost, leakage prevention, convenient assemblage, etc.

Description

Sprayer

The utility model relates to sprayer, is mainly used in agricultural and goes up spray liquids such as prevention and elimination of disease and pests or health and epidemic prevention, belongs to agricultural plant protection machinery.

As the equipment for plant protection of control diseases and pests of agronomic crop, the most frequently used is knapsack sprayer.Knapsack sprayer is usually by manual operation, and is relatively simple for structure, uses flexibly, convenient, and its critical piece has liquid storing barrel, and the pump assembly of aspiration medicinal liquid drives the control stick of pump, and sparge pipe, spray boom, shower nozzle etc. are formed.So-called pump assembly is pump assembly and air chamber, and pump assembly comprises cylinder body, piston and piston rod etc.The pump assembly and the air chamber of existing sprayer are the split manufacturings, the air chamber jar is that single hole discrepancy communicates with carrier pipe, when the pump discharge opeing, some enters in the air chamber, and when the pump imbibition, liquid output in the air chamber, the major defect of prior art is that the pump assembly volume is big, structure is complicated, makes, assembles trouble, and easy seepage.Be on the other hand the pump assembly generally by the metal material manufacturing, by the agricultural chemicals rust corrosion, some uses stainless steel material instead easily, but cost is expensive.

The purpose of this utility model is the defective that overcomes prior art, provides a kind of the pump assembly is improved design, makes its volume-diminished, assemble laborsaving, the sprayer of reliable sealing backpack.

The technical scheme of the utility model sprayer is: by liquid storing barrel, the pump assembly of aspiration medicinal liquid, drive the control stick of pump, and sparge pipe, spray boom, shower nozzle etc. form, the cylinder body of its pump assembly and air chamber jar are made one, piston and piston rod are arranged in cylinder body, piston rod first line of a couplet connecting rod and control stick, feed liquor valve and tapping valve are equipped with in the bottom of cylinder body, and the discharge opeing valve port connects the bottom of mozzle to the air chamber jar, woven hose is installed, woven hose first line of a couplet sparge pipe in air chamber.

Sprayer of the present utility model, its cylinder body are upper cylinder body and lower cylinder body, and upper cylinder body and air chamber jar are annotated by plastics and made one arranged side by side.

Sprayer of the present utility model, its upper cylinder body and air chamber jar top are shaped on and are connected and fixed plate.

The utility model discloses a kind of sprayer, compared with the prior art, have following characteristics: the one, cylinder body and air chamber jar are made one, link to each other side by side, make volume-diminished, and help adopting plastic processing, to make laborsavingly, corrosion-resistant, cost is low; The 2nd, from the cylinder body to the air chamber, connect, and in air chamber, woven hose is installed through mozzle, sealing problem solves easily, prevents seepage; The 3rd, fixedly assembling is very convenient, laborsaving for air chamber jar, cylinder body and liquid storing barrel etc.

Fig. 1 is the structural representation of the utility model sprayer;

Fig. 2 is the utility model spray affair device cylinder body and air chamber jar organigram.

Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is done detailed explanation.

1, liquid storing barrel; 2, base; 3, mozzle; 4, nut; 5, tapping valve; 6, feed liquor valve; 7, lower cylinder body; 8, upper cylinder body; 9, air chamber jar; 10, woven hose; 11, be connected and fixed plate; 12, piston rod; 13, control stick; 14, connecting rod; 15, sparge pipe; 16, spray boom; 17, shower nozzle; 18, handle; 19, bung; 20, pan; 21, piston; 22, connecting plate.

The utility model relates to the sprayer that sprays insecticide pesticide, described liquid storing barrel 1, the base 2 that liquid storing barrel connects down, be positioned on the control stick 13 in the base, connect the connecting rod 14 between control stick 13 and the piston rod 12, the sparge pipe 15 of spraying system, spray boom 16 and shower nozzle 17, and the handle on the liquid storing barrel 1 18, pan 20 and bung 19 etc. are same as all prior arts, comprise various pattern.Main improvement design is the pump assembly, cylinder body can adopt upper cylinder body 8 and lower cylinder body 7 to help processing, upper cylinder body 8 is annotated by plastics with air chamber jar 9 and is made one arranged side by side, connecting plate 22 is arranged between the two, and can make reinforcement, as shown in Figure 2, top is connected and fixed plate 11, not only plays connection but also be used for fixing on liquid storing barrel 1.Piston rod 12 and piston 21 are installed in cylinder body, and piston rod 12 outer walls can be shaped on guide ring, and woven hose 10 is installed in air chamber jar 9.Feed liquor valve 6 and tapping valve 5 are arranged in the bottom of lower cylinder body 7, and the discharge opeing valve port connects the bottom of mozzle 3 to air chamber jar 9.When sprayer was worked, the soup in the liquid storing barrel 1, in air chamber jar 9, was pressed into woven hose 10 again and sprays from sparge pipe 15 and shower nozzle 17 by mozzle 3 to tapping valve 5 through feed liquor valve 6.
