Any construction work on the site, whether the construction of the base buildings, screed or arrangement of blind area, can not do without the use of concrete solutions. Wanting to save money on the construction of many of the craftsmen kneaded it by hand. If for the production of several liters of solution you can do manual labour and a normal shovel, to obtain significantly large amounts it is better to use a special mechanism — a concrete mixer. The mechanism of such a device is quite simple. Due to the described in the article step-by-step instructions anyone can understand how to make a concrete mixer with his own hands, and manufacture need in the household appliance in just one day.

Option #1 — hand mixer from the barrel
The simplest version of the mixer device driven through manual force.
Manual Assembly in the process of operation entails use of large muscle strength. However, in case of incomplete filling to set in motion concrete mixer can and a woman
Thinking through how to make a cement mixer for home use, many owners try to choose the option that do not involve large financial expenditure. The best option – a manufacturing device of metal drums and frame, welded corners and bars.
As capacity is perfect cask with lid with a capacity of 100 liters and above. The ends of the cover drill holes to accommodate the shaft and to the bottom cap mount flanges with bearings. Then on the side of the cylinder wirecut hatch — a rectangular opening Hatch 30×30 cm place preferably closer to the end which in the process will be located on the lower side.
For a snug fit of the lid in the process of operation of the device at the edges of the hatch, you need to stick a soft rubber. Pin on a barrel carved piece using the loops on the nuts and bolts or any constipation with the use of hinges.
The shaft should be placed at an angle of 30 degrees, and the structure mounted on the frame, made of 50×50 mm. corners of the Finished design need to dig into the ground or firmly secure on the surface. The shaft can be made of two steel rods d=50 mm.
The design is ready to work. It remains only to fill the reservoir of all ingredients, close the lid and using the handle to carry 10-15 rpm
To unload the finished solution from the tank, you need to substitute any container under the barrel and through the open hatch upside down barrels to throw spiced with a solution.
Option #2 — manufacture of electric concrete mixer
Electric mixers are classified as the more advanced models, they are driven by a motor.
Preparation of the basic elements
To make the mixer, you need to prepare:
- Metal tank;
- The electric motor;
- Drive shaft;
- Metal corners or rods d=50 mm for blades;
- Two bearings;
- Elements for the frame.
Using a barrel with a capacity of 200 liters per load you can get up to 7-10 buckets of the prepared solution, sufficient for one cycle of construction works.
For the manufacture of concrete mixers you can use the finished barrel, or cook a capacity from 1.5 mm sheet steel. However, it is necessary to possess certain processing skills
To increase the mixing properties of the unit, the tank can be equipped with helical blades. Cook them they can be angles or rods, placing them at an angle of 30 degrees, and giving them the shape of the inner contours of the tub.
For a mixer you can use the engine from any equipment (e.g. washing machine). But choosing the drive motor is better to stop your choice on this, which is able to provide the speed of rotation 1500 rpm, and shaft speed not exceeding 48 Rev/min. Thanks to these characteristics it is possible to obtain a high quality concrete mix without dry patches. For the primary power module would also require additional gear and pulleys belt drive.
Assembly design
Both sides of the tank drilled holes to connect the shaft with the drum. The arrangement of the hatch of the tank occurs by the same principle as when assembling the hand mixer. To the bottom of the tank is welded a ring gear, which is part of the gearbox. There is fixed and gear with a smaller diameter.
To turn a regular tank into an electrical mixer, you need a piece of pipe, which will later be welded to the tank, insert bearing with large diameter, and then the shaft connecting with the engine.
Supporting structure — the frame can be made of wooden strips or planks, metal bars, pipes or corners 45×45 mm
To make a support structure of the mobile, you can optionally equip its wheels, which are mounted on the squared end of the shaft, made of rebar, d=43 mm.
To facilitate the work with the device, the mixer preferably equipped with a rotary device. To assemble it simply. To this end, through welding it is necessary to connect two metal pipes ø=60 mm, with two supports and bearing housings. It is fixed in bearings of the frame device can only weld end caps and tipping handles.
To secure the rotary device in the working position, need in the front ring and the adjacent pipe wall to drill a vertical hole which is inserted a wire pin 8 mm diameter.
Video examples from the masters-yourself-er
Finally, I would like to show a couple of video examples. Here is the production version of the gas cylinder:
But such a mixer can be done if the regular tub to attach the motor:
