Description

Manpower water pump

The utility model relates to a kind of agricultural and irrigates by lifting water to a higher level with a water pump, etc. machinery, is used for the agricultural production and the life of farmers of rolling country, when lacking power source, and the machinery that uses manpower to draw water and spray water.

A kind of known centrifugal suction engine (being commonly called as water pump) when reaching certain rotating speed with the power impeller, is extracted into higher height to water; Another kind of known manpower turns over waterwheel, and when making blade tank reaches certain speed and moves upward sidewards with manpower, water is toward eminence stream.There is following shortcoming in these two kinds of water plugs:

1. drive the water plug of water pump with power, the two is complete for necessary power and energy, just can draw water.

2. to turn over the volume of waterwheel big for manpower, and carrying is difficult, effort, hard, efficient is low, lift is low.

The purpose of this utility model is to avoid the deficiency of above-mentioned two kinds of existing water plugs, provide that a kind of cost is not high, volume is little, weight is light, be easy to carry, without power and energy, use manpower just comparatively effortlessly water to be extracted into the machinery of higher height.The situation of alleviating the rural energy anxiety to a certain extent under given conditions reduces labor intensity, and helps farming and pays industry production, is particularly conducive to rolling country peasant's production and life.

The purpose of this utility model can reach by following measure: by chassis (1), be installed in the castor (2) under the chassis, foot lever (3), the both feet that are installed in the personnel selection on the chassis are stepped on two foot-operated speed change gear (4) and supports (5) that make it to rotate respectively, be installed in the water pump (7) that flywheel (6) on the output shaft of speed change gear and output shaft drive its rotation, rack-mount seat (8), handrail (9), be installed in the intake pipe (10) on the water pump, outlet pipe (11), the shower nozzle that is used to spray water (12) and the connecting piece that are installed in the outlet pipe end constitute.

Chassis in the utility model technical solution (1) can be spliced with metal section, and its shape is decided according to the needs of member installation.

Castor in the utility model technical solution (2) is installed in below the chassis, can be with rubber tire or iron tyre and corresponding shelf composition, as short-haul operation.

Foot lever in the utility model technical solution (3) is fixed on below the chassis, form by screwed pipe and the screw rod that is inserted in the screwed pipe, one garden dish is arranged at the screw rod bottom, can increase area of contact, when screw rod is rotated, adjust the length of foot lever with the lifting of screw rod, can the leveling chassis and make this machine location.

Speed change gear in the utility model technical solution (4) can adopt belt speeder, chain speed change gear, speed change gear, worm and worm gear speed change gear, also can unite use to several speed change gears wherein.

Flywheel in the utility model technical solution (6) is installed on the output shaft of speed change gear, makes water pump have stable rotating speed with its inertia, and makes the starting back laborsaving.

Water pump in the utility model technical solution (7) is not high, the lower-powered micro pump of rotating speed, by the output shaft drive of speed change gear, and also can be with the impeller and the output shaft direct connection of water pump.

Shower nozzle in the utility model technical solution (12) is contained in the outlet pipe end, uses when need are sprayed water.

The utility model is compared original technology and is had following advantage:

1. compare with the water pumping power machine, this machine is without power and energy;

2. turn over waterwheel with manpower and compare, this body is long-pending little, and weight is lighter, unloads lower support frame and seat, is easy to carrying (just can propose with a hand, also can two people lift or a people walks away);

3. have higher lift, more laborsaving;

4. field irrigation and domestic water all can use this machine;

5. load onto shower nozzle at the outlet pipe end, can be used for nursery or field management water spray and fertilising the seedlings of cereal crops;

6. load onto the fine and closely woven string bag at the pump intake place, the liquid dung in the peasant manure pit can be drawn up the mountain, the peasant needn't go up a slope with carrying manure bucket on the shoulder.

7. the cost of this machine is that the cost of miniature suction engine of same power of power is low by about 50% than with the motor, and the peasant affords.

The utility model further describes below in conjunction with accompanying drawing and embodiment:

Fig. 1 is a plan view of the present utility model.

Fig. 2 is a left view of the present utility model.

Fig. 3 is the A-A sectional view of Fig. 1.

Present embodiment mainly is made of chassis (1), castor (2), foot lever (3), speed change gear (4), support (5), flywheel (6), water pump (7), seat (8), handrail (9), intake pipe (10), outlet pipe (11), shower nozzle (12) and connecting piece.

Chassis in the present embodiment (1) is a rectangular, is spliced with metal section.

Castor in the present embodiment (2) is installed in below the chassis, can move as short distance with rubber tire or iron tyre and the shelf formation that wheel is installed.

Foot lever in the present embodiment (3) is installed in below the chassis, is made up of screwed pipe and the screw rod that is contained in the screwed pipe, and garden dish is arranged at the screw rod bottom, is used to reduce pressure; Rotating screw bolt can make foot lever elongate or shorten; Hole, one garden is arranged at the screw rod bottom, and available extension lever rotates screw rod.

Speed change gear in the present embodiment (4) is by the bearing support one (13) that is installed on the chassis, bearing support two (14) and bearing support three (15) with two bearing hole positions, the foot-propelled axle (16) on the bearing support one of being installed in pair of bearings supporting, with bearing support two supporting one ends, again with bearing support three its other ends of supporting, and put the input shaft that is parallel to each other (17) and the output shaft (18) of two bearings respectively, be installed in the hinge wheel (19) on the foot-propelled axle, crank (20), foot-operated (21), be installed in the minor sprocket (22) of a termination of input shaft, be installed in mutual meshing gearwheel (23) and small gear (24) on input shaft and the output shaft respectively, be installed in the vee-pulley one (25) on the output shaft, be installed in the vee-pulley two (26) on the water pump spindle, connect big, the chain of minor sprocket (27), the vee belt (28) that connects two vee-pulleys, and other connecting piece constitutes.Draw key is housed on the minor sprocket, only drives input shaft and rotate, can not drive axle and reverse along a direction.
