With the growth of livestock per farm farms there was a need of increasing the food supply. Forage – a very laborious process, requiring great effort and fine days weather loosens it a little. Manually, the old fashioned way with a scythe and a rake, with this task to cope became more difficult. Meanwhile, in private households gradually began to appear on trucks, tractors. It took them various agricultural implements, trailers and ancillaries. In particular, hay began to use balers. Now hay pressed in rolls of approximately 200 – 300 kg. They have to be transported from the field to the storage place. But try to raise the weight and throw in the truck or even lift on the truck tractor! So I got the idea to make the so-called tractor lift coils – rear unit operating from the tractor.
“ROLL” HAY — STACK
Picking up the prototype for the model with open wheels (the trace of A class), we did not immediately notice the car “Lotus” with a modest architecture of the body and a relaxed silhouette — machine like a machine. But one of the guys asked “innocent” question — why would he ship the pipe? After looking at the car more closely, we realized that the prototype carries many more mysteries: where is this race car exhaust pipe, where futerko, inlet air into the cylinders of the engine, why so few intakes, why is the car the same front and rear wheels, etc.? They began to understand, and found that perceived at first as “the ugly duckling” “the Lotus-56V” can rightfully be considered a “Swan” of motor vehicles.
Rocket “07” — the first rocket was working 2nd brigade Gird (Group of study of reactive motion), led by K. M. Tikhonravov.
Autocostruzione — a long-standing passion of Krasnoyarsk Vladimir Alexandrovich Hassan. The readers interested in self-made machines, will probably remember and “Mini-Valga”, and “Buggy-350″… And here’s another one, just finished work. But unlike the previous one, where A. Hassan was the developer and Builder of the car, here he plays the role of the musician — the entire design and engineering linkages took on the son of Vladimir Alexandrovich, engineer-motorist Vladimir Hassan. And so, family debut.
Me years members Vorovskogo mug Seversk high school № 44 of Krasnodar territory are engaged in constructing a small-sized agricultural machines. The guys understand the importance of this kind of creative search, because has experienced the difficulties associated with manual tillage. Collective and state farms simply: to handle their huge fields of a set of mechanisms. For small parcels such cars practically does not exist a shovel, a hoe, a rake here, perhaps, and all the mechanization on the school or piticescu plot.
Since childhood read “modelist-Konstruktor” — he learned a lot of interesting technical ideas and developments. According to publications in the journal while still in school, redid the bike in the sled on the tires, and then with a crawler gear. During the construction of the manor house has designed a variety of tools and mechanisms to facilitate construction. And now with great pleasure engaged in technical creativity. Today, mainly from units and units decommissioned or abandoned equipment, collected four tractors, which offers its readers.
To transport various cargoes to their farm of Simonov from the village of Podsosenki Saratov region made the tractor chassis. The engine capacity of 40 HP with gearbox’s used car “Zaporozhets”. The transmission complements the wheel gearboxes from a Bulgarian truck. The frame is welded from channel No. 12. Front axle is a shortened rear axle from the car UAZ-469 with the wheels (they brake and steer). Rear wheels — of the truck GAZ-66. Payload chassis — 1T transport speed is 45 km/h. fuel Consumption is about 6 liters per hour.
General interest competitions rakatomalala (the first open championship of Asia and championship of Russia) resulted in a model of Rotorua (class Ѕ9А) Russian athlete Vladimir Menshikov. Will talk about it in detail. This model is schematically recall the development of the first of rotochutes (1994 — 1996) at the dawn of this category. It was then suggested that a similar version V. Menshikov. But the current model is at a higher technical level. It does not apply to the type of rotochutes container type. The body of the model consists of four blades made from balsa plates with a thickness of 1 mm. folded along the axis of the model, each blade, or rather its width (chord), is 1/4 of the circumference of a circle with a diameter of 40 mm.
To check the symmetry of the punch of a model of the ship on the drawing manufactures all of its frames (or polosamote). Although this work is easy, but requires time and material cost. For ship modeling clubs and laboratories, which launched production models of ships of various classes, I suggest using a universal mechanical pattern. It reliably and quickly provides control of compliance with the hull lines of the model of the vessel its theoretical drawing and defines even the most minor asymmetry to each side of the punch.
In the journal “modelist-Konstruktor” was published an article by a teacher from the city of Severodvinsk Vladimir Arkhipov, dedicated to the manufacture of plastic fine-grained cylindrical gears for motor car, ship and plane models on the example of gear made of polyethylene with the basic settings of m = 0.8 mm and z = 8. Continuing the theme, the author offers the readers a mold similar to the previous one, but with one fundamental difference — it is designed for making small batches of disc gears with the end location of the tooth.
