Self-made concrete mixer - is it possible? self assembly and

Any builder will be able to say that the preparation of the solution manually in any capacity using a shovel or chopper is extremely difficult, especially when it is needed very much, therefore, the concrete mixer, assembled with its own hands, can be an alternative to manual labor and factory assembly. Of course, the mechanism of handicraft production should differ favorably in value, otherwise there is no point in it - it is easier to rent it or buy it in a store.

Поэтому составные элементы механизма должны быть, что называется «под руками», а само устройство - наиболее простым. Сейчас мы постараемся собрать такую конструкцию, которая доступна для любого домашнего мастера, а также посмотрим видео в этой статье, наглядно затрагивающее нашу тему.

Do it yourself

What we need

• First of all, in order to make a concrete mixer with our own hands, we will need a tank and for this, as well as possible, an old metal barrel will fit, provided that it does not rust.. However, even if there are mechanical damages on it, then they need to be repaired by welding a sheet metal patch there or use this place for the loading and unloading opening. The early contents of such a tank does not matter, because the smell in this case is not a hindrance, especially since it will disappear in several batches.
• You will also need a piece of metal pipe about 40-50 mm in diameter, as well as flanges, but here it is a little more complicated. However, although their price in the store is not very high, it is better to look for such parts at home - it is very possible that they will be found among the old auto parts and you will only need to modify them to the desired size. In addition, you will need smooth fittings for the gate section of 14-16 mm, a different metal profile for the support system (angle, channel, square tube and the like - everything that exists in the household), as well as bolts and nuts for fastening.

Note. Such elements for the assembly is not necessary to look in your garage - they can often be found at the points of delivery of scrap metal or simply ask around from the neighbors.

Getting Started

First of all, we will rework (if necessary, repair) the barrels we have and we need to find a center on both end covers or bottoms. It will be quite simple to do this - cover the butt with a whole sheet of paper and beat it along the edge of the barrel (like a gasket). Then fold the resulting round sheet in half and in two directions mark the diameter - the point of intersection of the diametric lines will be exactly in the center.

In these places you need to fix the flanges, but first you just make holes for the shaft with bolts, using for this purpose bolts at least 8 mm in diameter - after all, the load will be serious.

Также вам нужно будет вырезать прямоугольное отверстие сбоку, примерно, 300×250 мм - здесь в дальнейшем вы прикрепите загрузочно-разгрузочную дверцу. По краям этого люка для герметизации нужно наклеить полоски из мягкой резины шириной 5-10 мм, только для этого тщательно зачистите поверхность, иначе при работе прокладки отклеятся.

Мы рассматриваем, как сделать своими руками бетономешалку, и переходим к крышке - её размеры должны превышать размеры люка - в данном случае достаточно будет 280×340 мм - чтобы крышка плотно перекрывала отверстие. В качестве навесов лучше всего использовать карточные петли (несъёмные), чтобы крышка не упала во время работы.

For closing, you should use a corner that is pressed against the bolts, but the best way to do this is to use the locking carabiner latches, if there are any in the household, this is very convenient.

Now go to the mounting flanges - they need 4 pieces - 2 at each end, inside and out. We can assume that this is a mandatory instruction - the fact is that the barrels are made of thin sheet steel, which simply will not withstand the load, if the flange is fixed with bolts directly to the bottom, but if you hold the metal sheet on both sides, it will withstand, since the load will be distributed evenly.

You make a shaft out of the pipe that was set in advance, just try to ensure that the inside diameter of the flanges coincides with the outside diameter of the shaft, that is, the pipe and scald the joint.

You attach a lever to the shaft - for this you can use a thick metal strip or pieces of reinforcement with a cross section of 14-16 mm and you can make a handle from the same reinforcement (but surely smooth-walled) and all this can be fixed by electric welding, and for ease of rotation a pipe can be put on slightly larger diameter.

It is noteworthy that the concrete mixer from a flask with his own hands is done on the same principle.

Мы продолжаем рассматривать тему, как изготовить бетономешалку своими руками и теперь сделаем три-четыре гребёнки, которые будут помогать смешивать компоненты между собой и для этого можно использовать металлический уголок 50×50 мм и гладкостенную арматуру или квадрат сечением 14-15 мм (узнайте здесь, как забетонировать столб).

The pins are best sharpened so that the solution flows freely from them without forming growths, and place them at a distance of 50 mm from each other and weld to the corner if it is round or bolted if it is square. Since the corner for the entire length of the barrel will be very inconvenient to mount, then each of the combs is best cut into two parts, fixing to the wall with bolts 6-8 mm in diameter.

The bed can be assembled from the most different profile, the main condition that it turned out to be strong enough - everything will fit here - a corner, a channel, a profile pipe and even thick fittings. It will, of course, be very good if you can find suitable for the shaft bearings for the shaft, fit them and fix, having fitted a seat on the bed ears so that the barrel can be removed, but at the same time, this will ensure free rotation.

According to a very similar scheme, you can install a gearbox for a concrete mixer - with your own hands having assembled an electric drive from an engine running from 220V - if all this is found in your garage, then such a device will be very convenient. But here we should not forget that your goal is to assemble a cheap and practical unit - otherwise it is better to rent a concrete mixer.

Note. If you still decide to use an electric drive, then it is best for you to use a 2.2 kW single-phase motor, approximately 1500 rpm, although this parameter is not critical, as it is governed by the diameters of the pulleys. Also do not forget that the simpler the construction, the easier it will be to repair the concrete mixer with your own hands.

Conclusion

Также, используя принцип вышеописанной конструкции, будет возможен такой вариант, как бетономешалка на трактор своими руками. Только здесь шкив на редуктор вам нужно будет прилаживать от дизеля (см.также статью «Железобетонные прогоны – все, что нужно знать о данном виде конструкций»).

Successful assembly!
