DRIED FRUITS AT HOME

28.05.201813.05.2018Small-scale mechanization

brickos — valuable fruit crop originated from Central Asia. However, not all varieties are suitable for drying because of the low content of the substance, the main component of which is sugar. It is usually early ripening varieties. To obtain high quality dried fruits it is advisable to use fruits with sugar content not lower than 19-20 percent.

The fruit should be removed when they reach a certain size, accumulate the largest amount of sugar will become normal, natural coloring.

WALK-BEHIND-TRUCK

Offer to readers design their new walk-behind. But before describing it, a little background. Village life is hard their daily monotonous work in summer and winter, rain and snow… Wanted to do something to alleviate all this work and care. I did a walk-behind tractor. And not generic, as usual, with a cart, because more needed in the vehicle. For the relative small size called it a “Humpbacked”.

TRUCK FOR MINI-CONSTRUCTION PROJECTS

All work on the farm or village is a combination of construction, transport and purely agricultural work. And if to facilitate the latter, you can purchase various small tools and equipment — from the tiller to the tractor, all other works good except a trailer to a passenger car, truck for walk-behind tractor or scooter “Ant”. Passenger car with a cargo trailer good for an asphalt highway, and to carry it peat or manure on unpaved roads, to turn on a dime or, God forbid, to reverse the lesson is that for a professional driver.

HIGH-SPEED ASYMMETRIC

The proposed control line speed model (C. F2А) asymmetric scheme designed and built in the aeromodelling club “Falcon”, under the leadership of its founder and coach B. I. Shibanova, the 9th grader Alexander Fights. Personally on command by the primacy of Moscow in 1999 among young men, he took second place. His model showed speed 118,8 km/h. Structurally, the model replicates the appearance of speed with which athletes perform, including master of sport international class. Its features include an asymmetrical wing and stabilizer (actually halves of both), located on opposite sides of the fuselage.

HAND PUMP

Well — vital structure on the estate, even if a centralized water supply system. Design it can be any. We have, for example, the popular tube-wells, good bearing rocks occur close. And simple tool for drilling (drilling rig spoon, chisel, coil and bailer screwed on the extension tube-rod), it is easy to get. For water many people prefer to use a pump type BKF or BKF 2-4 prefabrication. I am also quite happy with a homemade design which is so simple that it is available for repeating any.

RESCUE TENT

Plots is small. And when every square foot counts, then the space allocated to garages and outbuildings — not an easy task. An acceptable solution may be tent structures. Especially when considering time, especially material costs. To build the frame of almost any of the three options of awning, we have received the greatest distribution, will fit anything you have on hand: acceptable wooden poles, beams or even a pole.

THE SHEARERS, NOT ONLY

Shearing machines МСУ200 with a built-in handle three-phase asynchronous motor (200 Hz, 36 V, 100 W, 12, OOO rpm) we have in the village is not uncommon. Though slightly modified, with a reinforcing grommet for the power cable. This technique is popular in neighboring areas, where used by shearers of sheep and camels, as well as professionals postconservatism skins Karakul smusic. As a full-time source of electricity for it is a three-phase network with voltage of 380 V, which МСУ200 connected through electric machines-nye converters ИЭ9401А and ИЭ9403.

IN FLIGHT IN THE GYROPLANE

Who as a child dreamed of becoming a pilot, the conqueror of the fifth — the ocean air! A romantic nature will not abandon his dreams and in adulthood. And they can implement it: currently there is a wide variety of aircraft, which can fly even Amateur pilots. But, unfortunately, if these devices are prefabricated and offered for sale, the cost of them so high that most of them are practically inaccessible.

TRICYCLE-AIR SUSPENSION

A prototype of the proposed tricycle car was made by me on the basis of the motorcycle “IZH” chamber with two leading wheels and a steering ski. It seemed that the desired result is achieved: the machine ran well on the snowy road. True ski on Packed snow bad coped with its task. Spring revealed other shortcomings of this design. Riding on the roads in the thawed disabled even ski in stainless steel. Instead, I put the pneumatic chamber from 12.00—18,” but now more heavily affected by the lack of differential lock — a snowmobile was very difficult to manage.

CRANE MOTORIST

The owners of cars often have to be transported in the trunk of the massive thing. If no helper, then alone to ship them in the trunk or unload pretty hard.

Previously, I also had to strain with a tiller that weighs 55 kg. Now loading-you load, not a problem for me — I made myself for these purposes a special device. It is clear that it can be used not only for the cultivator.
