Cost of developing bicycle pump without oil or ele

The farmer developed the "bicycle" water pump without oil or electricity. The cost is 30 yuan

nowadays, the air on the earth is seriously polluted. With the implementation of low-carbon environmental protection, more and more people begin to abide by it. Most people will have their own small vegetable garden in their homes, which can add more green to nature.

nowadays, the air on the earth is seriously polluted. With the implementation of low-carbon environmental protection, more and more people begin to abide by it. Most people will have their own small vegetable garden in their homes, which can add more green to nature. Relatively speaking, planting a vegetable garden is not a simple thing. It requires a lot of complex processes, which are very hard, An old man abroad, facing this problem, invented a "bicycle" pump

this old man in the countryside comes from Portugal. From his invention, we can see that its overall structure is relatively simple. Most of its components are composed of the pedals and wheels of the self-made market cooperative modified plastic lifting car. A rope is wrapped around the recess of the wheel, and a rubber pad is also installed on the rope. The rope in the pulley passes through the rubber pipe and acts as a device to attract well water, A water pipe is connected above the rubber pipe, which is also more convenient for water outlet

the invention is also fixed on the ground by a square metal frame. Its operation method is also extremely simple. When pumping water, it only needs to gently shake the pedal of the bicycle. Driven by the pedal, the natural rubber speed regulator will pump water after adjusting the zero point of the sensor and adjusting the rubber pad. In the video, we can see that under the constant shaking of the old man, the water also keeps flowing out of the pipe, and soon a small bucket is pumped. This invention has simple operation, saves time and effort, and can not see any digestive energy source in the whole process. It can not only exercise the ability of hands, but also achieve physical exercise

according to my introduction, he spent only 30 yuan to make this pump, but don't underestimate the 30 yuan. It can irrigate five mu of land every year, and it doesn't need oil or electricity. It is very practical for some home gardens or small fields. When lamenting the greatness of this invention, we have to say that there have been experts among the people since ancient times
