MIXER FROM THE BARREL

Mixer when building a house. Cement mortar require a lot, besides he needs occasional stirring. A trough with a shovel is not important here assistants — nama with them before the aching all over my body and the quality of the mixture will remain low. Purchase the same brand design expensive not everyone afford.

It’s one thing to make a mechanical mixer for myself. For example, a mobile drive for a thorough “shoveling” of ingredients for mortar and with rotating mechanism for easier loading and unloading. And as a working capacity to use a 250-litre metal barrel with warnie blades.

 

Consider the kinematic scheme of such a machine for me — in the past aviation equipment — not easily made. Realize it helped… a junkyard, where rusted parts from discarded machinery.

With welding was not a problem — appreciate homemade “svarochnik”. With a number of turned work, as he tried to minimize that, things were more complicated. Of course, “the little stuff” performed by himself with the help of sandpaper, a drill and set of hand tools. Turning the main shaft and seats for the bearings had to charge u Turner from the neighboring machine shop.

 

 

 

 

Tank mixers made in several stages. Initially cut from the barrel blank with scalloped edges that are curled inwards to a diameter of 400 mm, and the joints prevail. As a bottom welded rim from a scrapped farm machinery. Unnecessary holes in it patched. Then welding the fixed ring gear of the flywheel of the engine of the GAZ-51 (centered!) main shaft, reinforced disc hub. The end of last drove under the roller tapered bearing 7307. Do not forget about the four Warnig blades from 8 mm steel plate.

 

According to the size of the tank and welded a frame from sections of steel pipe of square section. The result was the construction of two pillars United by a fork lift base. In front tabs, Yoshinari reinforced from 15 mm steel rod, wail sleeve (figure not shown) for fixing the axles of the wheels. To the heel at an angle of 20° to the horizontal attached to the pole — meter section of the hexagon 45. And to give the site extra durability, it has reinforced gussets.

 

On the racks by welding secured the bearings of the rotary mechanism. In addition, in the right of them drilled a hole that was waril axle sprocket with a homemade t-handle. Subsequently, on this same rack was placed and the sleeve stopper. Connection — welded, at the place of installation, the driven sprocket is placed on the shaft of the rotary mechanism.

At the other end of the shaft of the rotary mechanism fit three phase asynchronous motor (1.2 kW, 900 rpm). In home network 220 can be switched via a capacitor Bank with total capacity of 40— 80 UF (for it is the cradle formed by the two alosinae coupled with welded bushing and cheeks sub-frame) schemas that have been published in the journal “modelist-Konstruktor” (№ 8’95, 8’99, 10’2000).

 

Torque from the engine flows through the KPI-moremenu gear on the countershaft, bearing housings, which are mounted on the angled base. The latter are welded both to the shaft of the rotary unit and the sleeve, which is the case of roller bearings of the main shaft. In fact, it is a revolving structure under consideration (for a better understanding of the principle of its action) as three independent nodes.

 

Each has functional shaft with its pair of bearings. If the rotary unit is the bearings and the tube rotating in the bushings, then the intermediate — ball, and the main roller. Moreover, the application of the latter due to the need to withstand considerable axial stress during the loading and unloading of the tank.

 

Among other technical solutions, successfully working in a concrete mixer, a very soft “rubber” speed, reliability and stability of the structure, with the exception of its overturning by relying on the heel of the base frame. And, of course, the originality of the mechanism of a tension of the belt, where the desired effect is achieved by the weight of the engine, pulls the sub frame and non-slip V-belt transmission.

 

After ascertaining the advantages of my mixer, even in comparison with analogues of industrial manufacturing, the neighbors often asked to borrow it for a day or two. The special demand for the mixer — in the summer construction period.
