⚒ Mixer own hands: materials, tools, step by step guide

When construction is often necessary to mix concrete manually. Business is time consuming, requiring a lot of time. For smaller jobs, such as installing multiple columns, it's not a problem. But what to do when you need to, for example, to fill in foundation for a bath. Here and useful inexpensive concrete mixer, made with his own hands. After all, buying a unit - not a cheap. Today, on the basis of fotoprimerov, try to figure out how to make such a mechanism independently from ordinary iron drums.

How to make a concrete mixer: step by step guide with examples

To work need drum (200 L) chain and sprocket of the motorcycle, bearing, profiled tube, and corner piece sill. From the tool - Bulgarian and welding machine. And, of course, an electric motor, which will cause the unit to move.

Preparing to work the barrel

First, the barrel must be measured and then to mark into several equal parts. What will be more, the more accurate will pear.

With the help of a marker marked places cuts. Their length shall be up to the first rib rigidity. For starters, you can make a wide petals, and then divide it into equal parts.

Many believe that it is best to cut the side hatch and make the door for loading of cement, sand and water. However, this concrete mixer is not too convenient. After all, for the addition of each component, it will have to stop. Convenient, if everything will be mixed in a conventional classical pear, for the manufacture of a barrel should be prepared.

The first thing to be cut top. Dispose of it is not necessary - it is more useful later.

After the top portion is cut, it is possible to start cutting lobe marked earlier. By the way, when working with angle grinders do not neglect the personal protective equipment (gloves, face shield or goggles). Bulgarian - quite a dangerous tool.

The last thing to do when preparing barrels - notching petals at a slight angle. This will allow to make a tidy bag. When welding seams will look much neater.

Now, preparing to work a barrel is possible to start welding.

Pear Manufacturing: Materials, the procedure works

Of course, you can leave the barrel of a straight line, without making incisions. Then the welding work will be less. But there is one problem - the solution is to mix it inconvenient, and its volume will be less. That is why the need pear.

Bending the petals so that the joints are completely agreed, you need to grab them one to another, and after already fully boil. By the way, the seams do here is quite difficult - the metal is not so thick, and because, when excess current, it can burn through. It is better to seek professional help, if DIY is not enough experience in production welding.

Pear itself is ready. Following will only weld the keeper opposite (outer) side of the bottom piece of a pipe, which will play the role of supporting drive shaft. But now it is better to attend to the manufacture of the frame.

Stand for concrete mixers: the material, the algorithm works

The frame is made of profiled tube. It is difficult to explain in words of its shape, and therefore invite the reader to become familiar with a similar design fotoprimerom.

Next on this basis will be welded to additional elements. For example, for the stability necessary to lengthen the legs steel channel support, which are quite a lot of weight.

It is important that the welds were made qualitatively, because the base frame will be supported not only the barrel, which is not too heavy. It should be understood that in addition to the weight of the concrete inside the pear on the joints will be affected by vibration. Quite frustrating if in the process of concrete mixer simply fall apart.

On reception of the frame, top, welded pieces of pipe, cut in half, with the expectation that they freely housed inside the cross member, the retaining barrel mixer.

Sheer axis represents two segments of tube welded in the middle of the barrel on both sides. To strengthen the structure can be fixed on the barrel supporting plates which give rigidity.

Installation of the drive shaft at the bottom of the pear

Now, with the reinforcement platform drive shaft can be welded to the bottom of the barrel. It is a conventional piece of pipe, the diameter of which must fit to the inner race of the bearing. It is also necessary to cook the U-shaped frame made of the same profile pipe, which will hold the barrel on the frame. Both her rack welded to the cross tube, holding the barrel, which will be based on a frame, and in the center of the bridge is burned hole. From the outer part of the bearing location to be welded, and inside which house the drive shaft. When all of these items will be interconnected, concrete mixer acquire almost finished look. Will only be welded to the U-shaped frame (one of the pillars) extension cable, with which you can tilt the barrel when you need to dump ready-mixed concrete in the trough.

Mixer blades for thorough mixing of the solution

However, the barrel itself is not to mix concrete, if not weld inside the blade. To do this, you can use an ordinary steel bracket. Thus, it will be wider than the sides, the solution was carefully mixed. But there is a caveat. If you make too big device, then you have to install a more powerful electric motor - a weak engine can not simply turn the unit fully loaded.

The blades are welded at a slight angle along the inner walls of the barrel. It is necessary to consider how they will be inclined. When rotating electric pear solution should not rise up, otherwise there is a danger of spontaneous contents discharge when operating mixers. It is also worth adding a couple of blades on the bottom of the pear.

Important! It is best to weld the two of the four blades is in the field welding the retaining tubes. This will strengthen the board, which will have to load on the axle bearings.

Now you can paint the barrel and bracket to the frame, to give them a neat appearance, and proceed to the installation of electric mixers.

Installation of electric mixers with their hands

To mount a drive from a conventional electric motor, it is necessary to work hard, so it is more convenient, if the hand would be the engine, equipped with a gearbox. On its axis is mounted on the motorcycle asterisk, and a U-shaped frame mounted bracket. It is fixed on it and an electric motor.

Along the edge of the barrel, a circle, welded chain motorcycle, and the engine is set so that the sprocket ideally fall into the grooves. It turns out that when the motor shaft rotates sprocket pushes the barrel in the desired direction. In fact, the system is almost similar to the operation of the motorcycle.

The motor must be locked rigidly as possible. On his arm will account for a very large load.

Important! After the concrete mixer is put into service, it is worth remembering one very important nuance. Load components must be carried out in a rotating bulb. This will prevent unnecessary load on the motor bracket at start-up.

chain guard, if he needed to mixer

Many believe that the production of housing, which will hide the electric motor and sprocket, is a waste of time, but it is not. First of all, it provides operator safety. After all, with the cement mixer to an asterisk can wrap around sleeve overalls or its other part. And not the fact that the employee will be able to turn off the time setting. This can lead to very dire consequences.

The second function of the housing - drive protection against ingress of cement dust and other contaminants, which can significantly reduce the life of the installation. A cover can be manufactured from a cut at the beginning of the top of the barrel.

Connecting the motor: accessories

You can connect an electric motor, using a conventional key, but experts do not advise to do it. In the case of such a switch, the inrush currents will be large enough that will shorten engine life. Much better to use a powerful dimmer (dimmer). This will allow the supply current to the electric motor more smoothly. Driving rheostat connection is usually marked on his body, and therefore go into this in more detail, it makes no sense. The only thing you should pay attention - it must be installed in a plastic or metal box. After all, with concrete Mixing water is used, which can cause a short circuit. And, if the usual moisture itself is not so terrible for the contacts when it gets dusty on the short-circuit terminal is inevitable.

For additional support drums, on the U-shaped frame, you can set the jumper with a pair of rollers, which will draw a pear during operation.

Check performance mixers made with their own hands

Now, a concrete mixer got the final form, and it can be checked. To do this, you need only supply power and turn the rheostat. If we talk about how it looks, it is almost impossible to distinguish from the factory option (unless, of course, all the work performed neatly). Thus the cost of the unit, made with his own hands, is different in the smaller side of the factory option several times. In the photo below you can clearly see it.

Summing up

Difficulties in the production of concrete mixer electric with his own hands, of course, a lot. But the result is worth it. If done efficiently and accurately, then this machine will last a long time owner. But with heavy use, if the pear inoperable, it can always be replaced by newly made. At the same time, this work will not take a lot of time, and for Finance and all can be free.
