DIY manual concrete mixer from a barrel or flask for 1000 rudders

Concrete work is an integral part of any line. And there is not always electricity at the facility to connect the concrete mixer. I saw brigades of bricklayers kneading mortar for masonry (or for a semi-dry floor screed) with shovels on the site or in a large trough. Yes, that's an option. It is not done so long, but also not so simple: the load on the back and arms.

There is an alternative to this method, when there is no electricity or the concrete mixer itself - to make a homemade product with manual rotation from a barrel. And it is not at all expensive, but you need a tool: a welding machine, a grinder.

For assembly, a drum with a top cover not removed is required. These remain after draining the oil or various chemicals (antifreeze, for example). They are sold by car dealerships that sell auto oils on tap - on sale at 200-300 rub / piece In the store, pick up the barrel immediately complete with a small lid (cork). The barrel needs to be sealed.

From scraps of pipes and corners, you need to weld a frame for a concrete mixer. Scraps can be purchased at Wormet bases. Ferrous metal price:

RUB 25 / kg Metal for a concrete mixer is required by weight not more than 20 kg. Two bearings are also required (per axle). It is better to choose them according to the diameter under the axle - also used. You can go to any car service and pick up old wheel bearings from cars. The frame structure can be taken from these photos:

You need to think about a door in a barrel for pouring concrete. It must be sealed. The door itself is cut in the barrel, but the slots must be closed with metal strips. They are overlapped or riveted. Holds and opens the door on door awnings (with the ability to remove the door). The door is fixed to the lock for the sides of trailers and vans:

Painting the product at your discretion. Rusty elements need to be cleaned. IN this article I wrote about an easy-to-manufacture sandblasting machine. He will be like a rac by the way.

A short story about a similar construction of a concrete mixer, but from a different author. The concrete mixer was assembled in the 80s of the last century. If you fill the barrel with 12 buckets of rubble or sand, then two people will have to turn the concrete mixer. For this, the levers of the handles are made on opposite sides of the axis. But if there are 4-6 buckets of rubble or sand, then it is quite possible to twist one.

Some craftsmen make a concrete mixer from a barrel with the barrel positioned not along the axis, but with an offset (for better mixing). In this one, it will not work to mix concrete alone - only together. I don't see the point if 2-3 jumpers are made inside a barrel with a symmetrical arrangement (along the axis). This is quite enough.

If a 200 l concrete mixer is too large for your purposes, that is, a simple structure for a smaller volume from a standard container and also with a manual drive - this is a concrete mixer from a flask:

In rural households, many still have aluminum 40 l flasks. Someone began to use plastic containers (they are lighter and cheaper). And the aluminum ones are idle. The information below will allow you to use this flask. If you don't have a flask, you can purchase it on avito. Prices - from 900 rubles Probably, you can bargain for 100-200 rubles.

The design is similar to the barrel model. After mixing, it is necessary to provide a fixer for the position of the flask - for pouring concrete into a container (trough). It will be very inconvenient to do this without fixing the position. The same point applies to the concrete mixer from the barrel.

The flask clamp screws are needed to center the position of the container and to fix the flask in the cage: steel is not welded to the body of the aluminum flask.

I liked this construction of a concrete mixer from a flask:

Compact, lightweight, mobile (on wheels). For mixing small volumes of concrete without power - ideal.

In the article, I did not consider the options for the manufacture of electric concrete mixers. The assembly of such models takes place among self-builders, but it is expensive and complicated. Not everyone will decide on this. I think it is easier to buy a new small concrete mixer for 10-12 thous. rub. (overpaying only a few thousand). Because it will take more than one thousand to buy an electric motor and spare parts for a homemade one.

If there is an electric motor from an old washing machine available, then you can still assemble a small model. Somehow in another article I will try to show the easiest options.
