Almost one in three knows from personal experience that the roach with a shovel over the old trough for kneading the mixture - not the most pleasant experience.And every second knows that the stories of their friends.So the question of how to make the mixer with their hands not idle.After a little strained at the beginning, you can greatly simplify your life later on.Consider how easy it is to implement this venture into reality and what the pitfalls may be encountered in the process.

Existing versions of the devices and their differences ↑

main separation occurs by the way exactly how the process of kneading the mixture.There are the following four basic ways that are used in different models.

  • gravity method

is carried out by the auxiliary forces of our planet Earth.Rotating drum picks up on its walls a certain number of the mixture, which then falls back to the bottom of the remaining residues.So, striking again and again on itself, the mixture was stirred and appears to result in a sufficiently satisfactory for a builder.Use this option in a large-scale construction project impossible.The quality of the finished product is far from perfect, and the volume of the mixture is kneaded at a time small (otherwise will suffer quality).

  • mechanical method

The fixed capacity bombarded the necessary components, which are mixed with each other by rotating about an axis of the screw.Beyond these movements, the screw must be moved around the perimeter of the container when its diameter is much smaller than the diameter of the latter.This option is not used when large volumes of work, as the cost of electricity has a very large.When attempting to use in the home of a simplified version (drill with paddle mixer) can also comprehend the failure.The device is not designed for continuous operation, and if to take breaks, a mixture hardens.

  • vibratory method

mixture was kneaded in a stationary container with a special mixer, which creates a wave in it.Using this method, as a result, a solution of very high quality.The most commonly used in the works related to the construction of complex structures (eg, dams).The home is almost never used.

  • Combined methods

is the most common.Combined mechanical and gravitational kneading method.Either this rotating container with rotating nozzles within it for mixing, or is a rotating container with rigid edges at its interior walls.The quality of the finished product is several times higher than that of a gravitational method, and power consumption is several times smaller than when using only a mechanical method.

process of assembling the manual actuator ↑

Before you begin to understand how to make the mixer, to clarify what tools and parts we need while working.

  • with capacity of about 200 liters.The material does not really matter, it could even be durable plastic.
  • metal rod of circular cross section, which will play the role of the axis.
  • Nails 200 mm, which will be part of the comb is used for a more thorough mixing.
  • Two metal rack with a length equal to the height of the container.
  • Metal shaped pipes that are necessary to create a support frame and arms.
  • Crown for fixing the crankshaft axis.
  • hinges.
  • two loops (from the lock-hook).
  • rubber seal.
the manual drive
The photo does not show one very important element.To design lasts as long as possible, it is necessary to strengthen the place of a joint axis of the drum.The upper and lower lid container better weld the two metal rails, that crisscross each other

Virtually all connections made by welding, apart from the attachment ring to the side of the tank and the lid.

Assemble in the following order:

  • Welding struts.

rack height is adjusted on your own, but it is desirable that the finished structure is not less than 1.2 m. Otherwise, the process of filling the tank and release it from the mix is ​​problematic.Width perpendicular to the supports should be about twice the width of the tank.Oblique props are welded at an angle of 45 degrees.

  • The keying holes for the door.

opening dimensions are determined individually, but the most appropriate indicators - 30x30 cm. The cut area should be slightly reduced by no more than 0.5 cm (on each side).Along the perimeter of the hole is glued rubber seal.At the very door and a tank near the edges of the hole are mounted two rings from the castle, which will be stapled wiring.

  • Mount rake inside the tank.

K metal rails welded nails in increments of 5-10 cm. Reiki is welded inside the tank opposite each other.

  • Mounting axis.

to the side of the container with screws and nuts are attached crowns.The threaded hole axis, which in the joints welded to the crown.Fastening strengthened welded crosswise strips.

  • Fastening handles to the tank and the support frame.

top of the pedestal should be placed between the edge of the container and the axis.The uprights are drilled hole axis.Fastening by two metal washers, which are fixed with screws and nuts.Handles in the form of the letter "L" welded to the edges of the axis.

assembly process of electric drive device ↑

frame itself with the tank can be made almost the same as previously described.But instead of sticks, we performed a manual kneading, established a special unit with a motor.

Usually used in the factory ring gear elements, but for us it will not be the best solution.Firstly, its value is quite large.Secondly, to make such a self, too, is not everyone's strength.

worthy replacement can serve as a device assembled from the following components:

  • flywheel (on anyone, even the very old, the car);
  • gear-bending (using it will be connected to a flywheel starter).
  • wheel hub.
concrete mixer
To ensure the desired speed, should be supplemented with another gear and belt

addition there is one difference.The axis is not welded to the tank, it will be rotated by a motor, and itself the capacity will remain fixed.Inside the tank is not welded ridges instead welded to the blade axis, which will be carried out batch.

construction of concrete mixers
The photo shows the open design, but it is inconvenient fact that when high speed is strongly sprayed mixture.It is advisable to mount after the blades welded on top of the second part of the tank

independent manufacturing concrete mixers help accelerate construction work at least three times (in the case where a manual version).In addition, you get rid of the need not only to buy and expensive but not less expensive rental unit.
