How much fun gives the children the winter snow. Technical Arsenal of this kind of leisure is increasing every year: the sled wide variety of designs, snow-cats, snowmobiles and many others. With the arrival of spring comes the turn of wheeled transport: bicycles, scooters, skateboards. Those who are fond of snow, making myself a summer toboggan — a simple wooden cart on wheels-bearings. With a roar they rush downhill on asphalt tracks. And well, if this alignment is away from the city streets, bustling sidewalk, where the “rider” on his own, devoid of brakes the projectile is not exposed to danger. But better not to hope in case, and try to make it fun safe and useful: to make a simple single truck with steering and brakes, comfortable and safe route and organize sports competitions.
The laboratory experimental machines Orlowski city Palace of pioneers named after Yuri Gagarin a lot of interesting and original works. At the regional exhibitions NTTM they attract the attention of visitors of all ages. And no wonder! The search range of the young designers wide: training glider and walking robot, a flying car and microtracker. With every new car the guys are in the way of true researchers: outlining the purpose, carefully studying the existing experience, then, given their own capabilities, define the technical requirements to future design and finally design and build it. So was born a twin recumbent LEM-05 (laboratory of experimental machines, 5-I model), the creation of the device, which says the head of the laboratory of engineer V. I. Borodec.
In Latin language the word “cultivation” means “handling”, “cultivation”. If to explain in more detail, is the process of loosening the previously treated soil with simultaneous cutting of the root system of weeds. But cultivation is not only important for weed control. Tillage improves air and water regimes of the soil, which in turn enhances the activity of soil Microorganisms, creates the conditions for a friendly germination of seeds of cultural plants.
“Look through with great interest your section on “Small machines”: many useful find here Amateur gardeners. I decided to share a simple tool that has served me faithfully for years is terebilo for corn cobs”.
Unremarkable externally, water tower farm “Precepts of Ilyich” Spassky district, Gorky region. One year supplies the sleep of the villagers spring water. However, coming closer, you will not hear the usual noise water pump operation — he’s not here! And although the source is considerably below the level of the top of the container, water, with only a short respite, rise up! It is not a miracle? No, just Gorky handyman, locksmith-Borsi Yiwu L. Ceranova managed to invent and test the original hydraulic installation, in which for lifting water is used… the energy of the source. We offer our readers acquainted with the principle of operation and device.
For a man, far from technical creativity, the expression “reinvent the wheel” has a negative connotation:
It turns out that the bike besides one of the most ancient modes of transport: it is depicted on the recently discovered risuna Leonardo da Vinci related and 1495, that is, will soon celebrate its quincentenary.And at the same time, the bike is forever young, because with each new development it seems to be reborn. Today there are more than 20 thousand patents for a variety of venoconstriction! And the search continues. And it involves not only professional designers, but also a large army of Amateur enthusiasts and fans of pedal techniques, including readers of our magazine. The direction of this search are diverse, but among them we can highlight some General trends.
After reading in the “M-K” on the continuation of the contest “Small mechanization”, decided to take part in it. I propose a simple and compact micromelic. About the size can be judge by the pictures: the whole structure fit on my one hand. It is universal: designed for the production of corn flour of both large and fine grinding, crushing various zernatto and preparation of feed for livestock and poultry in their personal farms.
Processing small plots of land, traditional small-sized motorcycles, in our opinion, is quite difficult. Therefore, we have selected other flowsheet which consists of the following: the power plant is at one end of the plot, and the working body from the opposite edge of the plot moves toward the power unit. The operation can have two options: one course of work, and the reverse is blank; in the presence of blocks — both stroke work.
Offer for fans of DIY table homemade drill press using hand drill. On a solid base is mounted a hollow stand-tube, movably installed inside the stock. On the one hand, he sliced the rack to drive the vertical feed, and with another selected area for connection of the bracket with the guide bar through the longitudinal groove of the rack. On the bracket mounted hand drill and the motor. The drive from the drill motor is belt drive. Vertical supply node provides a mechanism assembled in a separate housing. The external dimensions of the machine depend on the chosen length of the strut and the base; the vertical stroke serves for the size — 100 mm.
