Description

The dual-purpose machine of spraying sprinkling irrigation

The utility model relates to a kind of both sprayable, again the device that can spray.

Chinese patent application numbers 91204256.7 discloses a kind of electronic dual-purpose machine of spraying that draws water, and comprises support, the water pump on it and motor, it is characterized in that being connected on the motor annular reflux, three joints are arranged, a water receiving tap, one connects the ball valve switch that draws water, also have one to connect spray switch, because soup exists in the water pump, easy cleaning not, cause the corrosive water impeller of pump, the water pump internal pore is excessive, and hydraulic pressure lowers, and atomizing effect is poor, secondly, the little (5m of the flow that draws water ³/ h).

It is good that the purpose of this utility model just provides a kind of atomizing effect, the spraying that flow the is big dual-purpose machine of spraying.

The utility model comprises support, the water pump on it and has the power of belt, three cylinder piston pumps are connected and composed in turn by the pump housing, cylinder barrel and suction seat, a bent axle is housed in the pump housing connects three connecting rods, three connecting rods connect three slide blocks, connecting rod one end is fixed on the bent axle, and the other end is connected with slide block, and the slide block other end is equipped with piston in cylinder barrel, above the suction seat pressure regulating valve is housed, the imbibition mouth of pipe, the backflow mouth of pipe and spraying hose mouth are equipped with in the side.Water pump is connected to suction valve and outlet pipe.One end of support has the push-and-pull hand, directive wheel and rubber tire is housed below the support.Power is diesel engine.

The utility model can be sprayed again because the sprinkling irrigation of will spray with the dress one, can be sprayed, and has made full use of power, and it is good to have an atomizing effect, operating maintenance conveniently, the characteristics that flow is big, the insecticide spraying and the pourings of drawing water such as the large and medium-sized woods of particularly suitable orchard, garden.

Below in conjunction with accompanying drawing, the utility model will be further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of three cylinder piston pumps.

Please read Fig. 1, be welded into rectangular support 14 with angle bar, an end is equipped with two universal guide wheels 2 below the support, and the other end is equipped with two rubber tires 11, and support tightens intrinsic water pump 13, power 8 and three cylinder piston pumps 5.Belt pulley at water pump, power and three cylinder piston pumps is on one side same, and protective cover 7 is installed.Power is the 175F diesel engine, and water pump is connected to suction valve 12 and outlet pipe 9, and when when drawing water, water pump is connected with diesel engine by belt 6, and when being used as when spraying, diesel engine is connected with three cylinder piston pump belt pulleys by belt.Three cylinder piston pumps are connected and composed in turn by the pump housing 24, cylinder barrel 19 and suction seat 18, a bent axle 21 is housed in the pump housing connects three connecting rods 23, three connecting rods connect three slide blocks 22, connecting rod one end is fixed on the bent axle, the other end is connected with an end of slide block with straight pin, the slide block other end is equipped with piston 20 in cylinder barrel, and an end of cylinder barrel is connected with the pump housing, and the other end is connected with the suction seat.Above the suction seat pressure regulating valve 4 is housed, the imbibition mouth of pipe 15, the backflow mouth of pipe 17 and spraying hose mouth 16 are equipped with in the side, see Fig. 2.Imbibition mouth of pipe tape splicing has the suction valve 1 of sebific duct, and the backflow mouth of pipe is connected to return duct, and the spraying hose mouth is connected to branch prong 3, divides prong to connect sebific duct and spray boom, has shower nozzle on the spray boom.The two ends of support are equipped with push-and-pull hand 10.

During the utility model sprinkling irrigation, water pump is connected with diesel engine by belt, the suction valve of water pump is placed on the place, water source, connect outlet pipe, the diesel engine outputting power passes through belt transmission, behind the starting mode of pump, under action of centrifugal force, the water gas of carrying under one's arms flows to impeller outer edge, form certain thickness white foam and high speed rotating water ring on impeller outer edge, because the effect of cut water, water and bubble enter air-water separation chamber by anemostat, this moment, flow velocity reduced suddenly, lighter gas is separated from water, and outside pump housing outlet effusion pump, the water after the degassing enters impeller by the water hole, mix once more with the impeller gas inside, under the impeller action of high speed rotating, flow to impeller outer edge again.Along with this process goes on again and again, the air in the water inlet pipe constantly reduces, and after gas drained, pump promptly entered normal operative condition, and water is served outlet pipe, can spray Yang Cheng 30m, flow 25m ³/ h.

During the utility model spraying, belt is transferred to diesel engine be connected with three cylinder piston pumps, the diesel engine outputting power passes through belt transmission, rotate three cylinder piston pump driven pulleys, make crankshaft rotating, do reciprocating linear motion with drivening rod promotion slide block and piston, thus the purpose of realization spraying.Suction valve on the three cylinder piston pumps is put in the explosive barrel for preparing, and return duct is also put in the explosive barrel, starts diesel engine, adjusts the operating pressure of three cylinder piston pumps, opens spray switch, can spray, and reaches desirable spray effect.When spraying is broken down, when shower nozzle stopped up, atomisation pressure was washed pressure regulating valve open, and soup flows back to explosive barrel from return duct, and spraying hose and three cylinder piston pumps can be damaged, and plays a protective role.
