Description

The pedal type manual suction engine

Technical field

What the present invention relates to is a kind of device that uses the foot-operated water pumping power that rotates, and belongs to agricultural technology field.

Background technique

general agricultural water pumping machine is all to use electric power machine or driven fuel dynamic engine as water pumping power, and the adaptive capacity of electric water-pumping machine is limited, does not possess the condition of electric power in a lot of farmlands, field; The fuel power suction engine uses the most universal in rural area the various wild environments of the functional adaptation of drawing water because this, still, the fuel power suction engine also has its shortcoming, such as: need to expend fuel oil, motor too heavy, be easy to break down etc.In arid season, one mu of required fuel cost of farmland drought resisting can be so that the economic benefit in this mu of farmland approaches loss of capital, " mire " that even makes the peasant fall into to can not extricate oneself into two: continuing to draw water to increase loss of capital, stop pumping and cause the withered loss of crops.

using Mampower pumping is that Farmers overcomes the method that electricity shortage and fuel oil rise valency, we see a lot of peasants and manually draw water with bucket, also there is the manpower of use to carry water, also someone uses men-power water raising engine, for example the shaking type water plug for well water pumping is exactly hand water pump in fact, be that such piston water plug draws water too slow, because such device piston surface friction drag that activity produces back and forth in pump process has been wasted people's part strength, such water plug manpower utilization ratio is very low, and it is excessively of a specified duration to use hand generation strength to be not suitable for the time, easily produce tired.

Summary of the invention

in order to overcome electric water-pumping machine and fuel oil suction engine to the economic burden of peasant's generation, the shortcoming of equipment heaviness, I have invented the pedal type manual suction engine, it only needs the people can automatic pumping as just stepping on bicycle above being sitting in, foot-operated draw water easily laborsaving, can make the people step on lastingly draws water, and pumping load is large, be that the best resists non-irrigated instrument strenuously.

pedal type manual suction engine the taked technological scheme of dealing with problems is: the pedal type manual suction engine mainly comprises a foot-operated rotational power plant, rotate accelerating unit, a gravity runner, a centrifugal suction pump and sit saddle, foot-driven lever, gear, belt pulley, fixed support etc., the rotation that foot-operated rotational power plant produces high-speed driving Centrifugal water pump after rotating the accelerating unit acceleration draws water, simultaneously, the energy produced when foot-operated rotational power plant accelerates is partly put aside in the gravity runner, when stepping of people slightly rested, the gravity runner discharges the energy of savings to supplement people's the resting of power energy, draw water and can not stop.

someone thinks that men-power water raising engine is very simply to install, just load onto foot drive device as the bicycle just passable, but can come up against a series of problems while being made veritably: one, the position problems of foot pedal apparatus and suction engine, the position relationship of foot pedal apparatus and suction engine can not be as the back-and-forth mode bicycle, back-and-forth mode can affect the discrepancy water pipe of water pump, the length of back-and-forth mode is not suitable for placing on narrow embankment, adopts the left and right mode also can produce the problem that foot-driven lever that horizontal transmission shaft is rotated hinders; Two, low speed steps and can not draw water, and general transmission does not produce high speed rotating, can not make Centrifugal water pump draw up water; Three, the people steps while drawing water and must constantly step, and slightly has the water outlet of slowing down or resting suction pump also follow diminishing or stop, and there is no that light natural sensation by bike.When the people advances by bike, the people has stopped stepping, but bicycle does not stop but moves on retarded motion, and although the suction engine that manpower steps has been installed the structure that steps of imitating bicycle, as flywheel, chain etc., but when the people stops stepping, suction pump can not continue to draw water, stopped getting off suddenly, is what reason this? we must carry out correct research again to bicycle: originally, the pedal-rotated unit of bicycle is not only direct ground-engaging wheel walking, make road wheel obtain rotation, simultaneously, whole bicycle (comprising the people on bicycle) is also in the walking of advancing, that is to say that the people has not only driven road wheel to obtain speed when pedaling foot pedal apparatus, also make whole bicycle (comprising the people on bicycle) also obtain speed simultaneously, the people puts aside a part of energy in whole bicycle when starting to accelerate to pedal bicycle, this energy is exactly the whole bicycle kinetic energy of (comprising the people on bicycle), the energy of another part is for the walking of road wheel, when pedaling of people slowed down or stopped a little, the kinetic energy of whole bicycle (comprising the people on bicycle) just discharges and provides road wheel to walk on, this walking is the walking of overcome friction and resistance of air.General manpower water pumping power machine is that the pedal power slewing gear directly drives suction pump, but whole suction engine does not have generation speed, still be still in there, therefore whole suction engine is not put aside energy is arranged, when the people of pedaling foot pedal apparatus stops pedaling a little, suction pump has just at once stopped drawing water, the people again pedal draw water just very painstaking.In order to address this problem, we are with an energy product accumulation of energy metering method: we have fixedly mounted a gravity runner on transmission shaft, the weight of this gravity runner is equivalent to a bicycle and a people's weight, when the people accelerates to pedal pedal-rotated unit, except driving suction pump to draw water, also must drive this gravity runner to rotate, at this moment this gravity runner has just been put aside kinetic energy, pedal and draw water while slightly resting as the people, this gravity runner just the kinetic energy of savings is provided provide suction pump to be rotated further to draw water, draw water and do not stop because the people stops pedaling, the people has obtained the same by bike light sensation finally.

the beneficial effect of pedal type manual suction engine is: the mode that the pedal type manual suction engine adopts pedal-rotated unit to draw water to side transmission suction pump, can draw water in narrow carrying on the bank, the pedal type manual suction engine adopts the foot-operated drive mechanism that imitates bicycle and adopts a gravity runner savings kinetic energy, make the people can discharge kinetic energy by the gravity runner while resting and continue to draw water stepping, the people step draw water light lasting as by bike.

Embodiment

below in conjunction with accompanying drawing to pedal type manual suction engine further instruction.

fig. 1 shows the structure of whole pedal type manual suction engine.The structure member of the pedal type manual suction engine in Fig. 1 is also few, can be divided into the two large divisions: the part on the left side is foot-operated rotational power plant, comprise: the gearwheel of bottom (3), with flywheel (4) and the drive chain of the imitative bicycle on the foot-driven lever (5) of gearwheel (3) coaxial rotation, top, what also have the grip of section (1) on hand and rear middle part sits saddle (6), all by fixed support (8), linked fixing, when the people takes while pedaling, the mode of work is with the same by bike; The part on the right, for accelerating and water plug, comprising: big belt pulley (9), belt (11), small belt pulley (10), centrifugal water pump (7) are all linked fixing by fixed support (8).To be a transmission shaft (2) by top pass to the acceleration on the right and water plug to rotation to the foot-operated rotational power plant of left-hand component, passed through accelerating process therebetween twice: be that the gearwheel (3) is connected with foot-driven lever (5) passes through the accelerating process of chain (12) transmission small flywheel (4) for the first time; To pass through again the accelerating process of the small belt pulley (10) on belt (11) transmission centrifugal water pump (7) on the basis of small flywheel (4) rotating speed through a big belt pulley (9) for the second time.By twice acceleration, the general rotation change that the people is stepped drives centrifugal suction pump (7) to draw water as high speed rotating.We see on the transmission shaft (2) in the middle of two devices in left and right a large gravity runner (13) have been installed, the rotating speed of this gravity runner (13) is the same with the rotating speed of transmission shaft (2), when its accelerated rotation, it has just put aside kinetic energy, when transmission shaft (2) while losing driving force, this gravity runner (13) also has kinetic energy, and this kinetic energy continues to drive transmission shaft (2) to rotate, and centrifugal water pump (7) continues to draw water.Two devices in left and right are connected into a pedal type manual suction engine by fixed support, above the people rides in, pedal while drawing water, and the people can sometimes be rested and pedal, but draw water, do not stop, and therefore the people feels relief freely, can work enduringly.
