Description

Multi-functional manpower pump

The utility model relates to farm machinery, particularly a kind of multi-functional manpower pump.

Existing agricultural water pump is many makes the energy with diesel oil, electric power, is mainly used in drought resisting, irrigation, large size and executes spray.Yet different farming are different to the requirement of water pump.Some needs big flow, low lift, and some is then opposite.Common manpower pump or be foot-operated or for shaking type, function is equally also very single.Be used to irrigate or spray or the pump of other purposes is difficult to get both on a machine.And these traditional manpower water pump ubiquity efficient are low, defectives such as heavy amount.Present little farmland, rural area, the present situation of many crops requires miniaturization, multi-functional and dexterous light manpower pump.

The utility model and purpose provide a kind of light, and be efficient and the manpower pump of multiple function arranged.

Described manpower pump comprises frame and the driving mechanism of being made up of transmission bearing support, goat's horn supporting rod, goat's horn axle, foot treadle etc.; Also comprise piston/cylinder and high low pressure changing valve, it is characterized in that, single-revolution wheel shaft (22) is housed on described goat's horn axle (19), dress wheel (21) is housed back on the axle (22), two foot treadles (6) through walking around this gyrostat pedal lifting rope (20) and interconnect, and be hinged mutually with the piston rod (12) of two-piston formula water pump cylinder body respectively through spindle nose latch (18); Respectively have a water inlet and outlet tube head (17) at the two ends of described cylinder body (16), one piston ring (23) is housed on the other end of piston rod (12), aforementioned water inlet and outlet tube head is placed on the cylinder body of piston ring both sides, each water inlet and outlet tube head on the cylinder body changes valve by a conduit pipe (5) and a high low pressure and links totally 4 on this valve.

The high low pressure changing valve has three ports, and the water inlet and outlet tube head (17) on one of port tube head first (26) and the cylinder body links, and two tube head second (27) of port link with outlet pipe, and three tube heads third (28) of port link with intake pipe (2).

In the chamber that aforementioned changing valve tube head third (28) and tube head first (26) link an inlet valve (29) is arranged, (29) place in the restraining groove that is formed by inlet valve table top (31) and inlet valve banking stop (36), can slide in groove; In the chamber that changing valve tube head second (27) and tube head first (26) link a flowing water Valve (30) is arranged, (30) place in the groove that is formed by outlet valve table top (33) and outlet valve banking stop (35), can slide in groove.

The utility model is by the work of piston cylinder and changing valve, under 50Kg body weight operator operation, and hour water lift amount 1.8～2.2T, water lift height 10～15m; Operate following hour water lift amount 2.5～3T 75Kg body weight operator, more than the water lift height 20m.Load onto special fog head, the mist amount is bigger 6 times than common agricultural fog head, about the high 4m of mist.Load onto the long drive nozzle, range reaches more than the 20m.The utility model compact structure, favorable sealing property.Cylinder barrel is made by Nylon, has higher intensity and degree of finish, is equipped with special acid resistant alkali piston sheet seal ring, and the friction ractor in water is extremely low, thus use lightly, durable in use, multi-use, it is required to satisfy peasants and herdsmen's many-sided effect.

Fig. 1 is the utility model structural principle schematic representation.

Fig. 2 is Fig. 1 side view.

Fig. 3 is a high low pressure changing valve structural representation.

Fig. 4 is the piston cylinder structural representation.

Among the figure: cushion block behind the 1-, 2-intake pipe, 3-front pods, 4-A, 4-B, 4-C, 4-D is four high low pressure changing valves with spline structure, 5-conduit pipe, 6-foot treadle, 7-hanging rope plate, 8-rotary support, the 9-screw of transposing, the 10-handrail, 11-taper knob, 12-piston rod, the hook of 13-bicycle, the two-sided plug of 14-, 15-pump housing latch, the 16-cylinder assembly, 17-water inlet and outlet tube head, 18-spindle nose latch, 19-goat's horn axle, 20-pedal lifting rope, 21-gyrostat, the 22-turning axle, 23-piston ring, 24-oil-containing cotton, 25-cylinder body hinge last, 26-tube head first, 27-tube head second, 28-tube head third, the 29-inlet valve, the 30-flowing water Valve, 31-inlet valve table top, 32-valve seat, 33-outlet valve table top, the 34-housing, 35-outlet valve banking stop, 36-inlet valve banking stop, 37-drip ring.

Step on right-hand tread plate, right cylinder descent of piston, right cylinder bottom water pressurized returns high low pressure changing valve 4-C, and the water inlet valve block pressurized on the 4-C is closed automatically at this moment, and confined water is had to wash open outlet valve and is entered the through draining mouth of pipe of center tube.Meanwhile, right cylinder upper cylinder body produces vacuum pressure, and 4-A absorbs water through main water pipeline from another high low pressure changing valve, backs down in the cylinder of the through right cylinder top of its inlet valve; This is same, the left cylinder reverse operation, and so whenever stepping on a foot treadle promptly has two cylinders to go out simultaneously, advance simultaneously again.Inlet valve in the high low pressure changing valve and flowing water Valve open and close in said process alternately, finish the hydraulic pressure conversion.

The utility model can be used for following aspect:

(1) utilizes the less water source of suction journey, give full play to the high voltage functionality of water, load onto the long drive nozzle of outfit, for spraying at a distance or the water delivery pouring in crops, fruit tree, nursery etc.; The high-power fog head of changing outfit can carry out the deinsectization operation.

(2) carry out the wet curing operation for five layers of outer within the walls and ground cement member or the build cement face in rural area with floor building.

(3) disappear for people, animal indoor and outdoor flushing, be fishpond oxygenation or the blood fluke epidemic-stricken area spiral shell etc. that goes out.

(4) from dark and extract the people, animal domestic water.

(5) be that the rural area is valued for Fire extinguisher timely.
