Abstract
The utility model discloses a duplex plunger pump for spraying insecticide. The belt pulley of the duplex plunger pump is connected with a motor, and the pump body is positioned between a water inlet pipeline and water outlet pipeline. The pump body is provided with a plunger piston, one end of an eccentric shaft is connected with the belt pulley, and the other end of the eccentric shaft is connected with the plunger piston. Water inlet valves and water outlet valves are respectively designed to be two, and are fixedly installed at the upper sides and the lower sides of a left pump cover and a right pump cover. An air chamber is fixed to the left-upper side of the water outlet pipeline, and is communicated with the water outlet pipeline, and a pressure regulating valve is fixed to the left-upper side of the water outlet pipeline, is communicated with the water outlet pipeline, and is also communicated with a water returning pipeline. The function of the duplex plunger pump is that the duplex plunger pump uses the motor to drive the belt pulley and the eccentric shaft to be rotated to spray medicinal liquid, and the labor intensity is reduced. The work efficiency is improved.
Description
The utility model relates to a kind of duplex plunger pump, particularly spray insecticide or build the spraying usefulness duplex plunger pump.
At present, the plant protection apparatus of the usefulness of spraying insecticide has the pedal-type sprinkler, and the characteristics of this sprayer are that pump is contained on the pedal, realizes spraying with lever manual double-cylinder plunger pump.Its working principle is: move rocking bar with hand, plunger is moved reciprocatingly in cylinder body, when rocking bar pulls back forward, two plungers move from left to right, right fluid ball valve is closed, the volume that right plunger and the right chamber of cylinder body tube are formed constantly increases, pressure reduces, soup in the case is washed right imbibition ball valve open by an imbibition imbibition sebific duct and is entered in the tube of right chamber, left imbibition ball valve is closed simultaneously, the volume that chamber, a plunger and cylinder body left side, left side tube is formed constantly dwindles, the soup pressurized in the tube of chamber and pressure rising, and soup is washed left fluid ball valve open and is entered air chamber.Push away before the rocking bar, effect is opposite.So constantly back and forth.Facts have proved, the sprayer of this structure, manual operation labor intensity is big, inefficiency.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of high working efficiency is provided, and labor intensity is low, and is rational in infrastructure, duplex plunger pump easy to use.
The purpose of this utility model is real like this looking: it comprises drive motor, belt pulley, plunger, and belt pulley links to each other with motor, and its pump housing is positioned in the middle of outlet conduit and the intake pipe, is provided with plunger in the pump housing.Eccentric shaft one end links to each other with belt pulley, and the other end links to each other with plunger.Intake pipe is positioned at the below of pump cover, and outlet conduit is positioned at the top of pump cover.Inlet valve is fixed in left pump cover inboard, and outlet valve is fixed on right pump cover inboard.The upper left side that air chamber is fixed on outlet conduit communicates with outlet conduit.The upper right that pressure regulator valve is fixed on outlet conduit communicates with outlet conduit and also communicates with water return pipeline.
The purpose of this utility model can also reach by following measure, and bearing crouches in plunger.Pump cover is a pair of, lays respectively at the two ends of the pump housing.The turnover water valve is respectively a pair of, corresponding in twos the placement.
The explanation of accompanying drawing drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is a positive view of the present utility model.
Fig. 3 is a sectional view of the present utility model.
Figure middle belt pulley (1), eccentric shaft (2), intake pipe (3), inlet valve (4), pump cover (5), outlet valve (6), outlet conduit (7), air chamber (8), plunger (9), pressure regulator valve (10), the pump housing (11), water return pipeline (12).
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
The utility model mainly adopts eccentric shaft (2) drive plunger (9) to do straight reciprocating motion, and the pump housing (11), pump cover (5), intake pipe (3), outlet conduit (7) adopt the separated and assembled structure.Belt pulley (1) is connected with motor, and rotating speed is the 1500n/ branch.The other end of belt pulley (1) is connected with plunger (9), and the stroke of plunger (9) is 15mm, and the pump housing (11) is placed between intake pipe (3) and the outlet conduit (7), and the two ends of the pump housing (11) are equipped with pump cover (5), are left and right sides pump cover (5).Plunger (9) is installed, supporting element, Sealing in the pump housing (11).Inlet valve (4), outlet valve (6) is respectively a pair of, and left pump cover (5) internal fixation is installed with inlet valve (4) and outlet valve (6); Also fixedly mounting outlet valve (6) and inlet valve (4) in the right pump cover (5).Air chamber (8) is fixed on the upper left side of outlet conduit, opens a hole in the middle of it and communicates with outlet conduit (7), and its capacity is 0.15L.The upper right that pressure regulator valve (10) is fixedly connected on outlet conduit also communicates with outlet conduit (7), and communicates with water return pipeline (12).The range of regulation of pressure regulator valve (10) is 1.5-2.5MPa, and water return pipeline (12) is connected with liquid medicinal case.
Working principle of the present utility model is: driven by motor belt pulley (1) and eccentric shaft (2) rotate, when eccentric shaft goes to when right-hand, drive plunger (9) is moving linearly to the right, closing left outlet valve (6) constantly increases left pump cover (5) chamber tube volume, soup is by imbibition sebific duct assembly, intake pipe (3) is washed left inlet valve (4) open and is entered left pump cover (5) chamber tube, right inlet valve (4) is closed simultaneously, right pump cover (5) chamber tube volume constantly dwindles, pressure raises, and soup is washed right outlet valve (6) open and entered outlet conduit (7) and pressure regulator valve (10) and air chamber (8).Eccentric shaft (2) goes to the upper left side and then acts on the contrary, so constantly repeatedly soup is sucked pump cover (5) chamber tube, enter pressure regulator valve (10) and air chamber (8) then again, air in the air chamber (8) pressure by compression raises, soup is sprayed by ejection electrodes, and unnecessary soup is from water return pipeline (12) liquid medicinal case that overflows back.
Compared to existing technology, the utlity model has following advantage:
1, replaces manual pedestal mounted sprayer fully, save the labour;
2, high efficiency, labour intensity is little;
3, reasonable in design is convenient to make and is produced;
4, volume is little, and is in light weight, and cost is low, is suitable for industrialized production;
5, of many uses, both can spray agricultural chemicals, can be used as the instrument of coated building again.
