A concrete mixer is a good device for preparing a cement mixture. It is necessary on the farm for construction work. The presence of a concrete mixer will make life much easier during prolonged repairs. It makes no sense to buy a new device, because it can be useful only a few times in life, but it is expensive, so it is more advisable to make a concrete mixer with your own hands.
Things to Consider
Of course, you can arm yourself with a shovel and stir the mixture manually, but then there is no need to talk about the quality of the screed. Using a cement mixer has several advantages:
- speed of preparation of building material;
- ease of unloading the cement mixture;
- a large volume of prepared solution;
- saving energy when harvesting building materials.
To make a concrete mixer, you will first have to get an old metal barrel. A container made of steel is best suited for this purpose.
There are design options where plastic barrels are used instead of metal containers, but they are most often small and not so convenient to use.
Regardless of which tank you choose for making a homemade mixer, it must be stable in order to ensure maximum safety for the person who will be working with the appliance.
Tools and materials
You need to take care of the tools in advance that will come in handy in the work. Of course, they will vary, depending on the complexity of the design, but have such devices on hand:
- grinder with a spare wheel;
- welding machine with electrodes;
- set of tools;
- soldering iron;
- bolts, nuts, screws, flanges, other consumables.
These are the basic tools that can come in handy when making a concrete mixer from a metal barrel . Don't forget to prepare your materials as well. The main thing is a container, preferably steel or made of dense metal.
Some people manage to make the device out of plastic tanks, but they are not as durable and not very convenient to use.
When looking for a suitable base for making a concrete mixer, you need to pay special attention to the size of the barrel . Experienced craftsmen recommend opting for a 200 liter container. It is considered the best option for preparing a solution, because the cement will not stagnate in it.
Find the driving shaft further; the metal from which you will cook the frame; bearings; pieces of steel that will be used to make blades or a gear ring that plays the role of a mixer, as well as an engine (if an electrical appliance is planned to be manufactured). The materials listed above should be enough for the manufacture of simple options for concrete mixers . If you already have any option in mind, you need to first study the drawing and buy everything you need.
It is not difficult to make a concrete mixer yourself at home, it is enough to take the process seriously and follow all the stages of manufacturing this useful device in the household. A do-it-yourself concrete mixer from a barrel is the simplest and cheapest option to acquire a cement mixer in a short time and without large material costs . The mechanical method of preparing cement is very long and laborious, so you can make a device that is equipped with a handle (with its help the drum will be set in motion).
The principle of operation of such a device is very simple . Under the influence of gravity, the mixture in the barrel falls and mixes, forming a mortar. There are several options for these hand-operated concrete mixers. For the manufacture of the device, you will need a steel barrel of any size, it is better if it is 200 liters. A place for the door is cut out on it, the already prepared mixture will fall out of it.
The holes do not need to be made very large, then the door hinges and the bolt that you come up with to close the door tightly may not withstand, and everything will fall out in the middle of the work process.
The metal frame on which the drum will be held can be welded from sleepers, reinforcement or other materials . The main thing is that it can withstand the workload. The number of legs is at your discretion, there can be 2 or 4. The barrel rotates with the handle. The described device is the simplest and is not suitable for preparing a solution in large quantities; for this purpose it is better to make a concrete mixer with an engine from a washing machine.
Making a concrete mixer with an engine yourself is more time consuming, but it will save a lot of effort in the future when preparing solutions . The electric motor itself is expensive, so the new device is not used in the manufacture of cement mixers at home. For this purpose, a motor from a Soviet top-loading washing machine is ideal. This technique was popular in the early 90s of the last century. You will need not only the motor, but also the metal base itself.
First, we will make a frame according to the same scheme as for a manual concrete mixer. Next, we proceed to the tank of the car. Close the drain and remove the activator, and in its place install the shaft with the axis. Homemade metal blades will act as a mixer, which are welded onto a metal base, and then attached to the inside of the washing machine . The finished drum is welded to the frame, and then the engine is connected. The motor is located at the back of the machine, holes are drilled at the corners, applied to the same holes on the motor, and then bolted. The motor itself is connected to the axle using a flange. There should be a distance of about 2 centimeters between them.
Before you start assembling a homemade concrete mixer, you need to find a suitable drawing. On the diagram, you can see the materials that will be needed during installation, as well as a general view of the final device . The detailed dimensions of the container, shaft, corners, as a rule, are not indicated on the drawing. But in the specialized literature for ready-made drawings and diagrams, you can find a detailed description of the process of connecting parts.
This will slightly facilitate the manufacture of a concrete mixer, because in the detailed instructions for the drawing there are digital links to the drawing, and even if a person does not know the correct name of a particular part, it can be easily found on the diagram.
It makes no sense to follow all the stages of creating the device, because each master has his own source materials and skill level, so you can safely make various adjustments in the course of work, replace parts and simplify the creation of a concrete mixer.
There are many options for homemade concrete mixers in the public domain, the main thing is to choose the one that suits you. The drawing can be done independently or you can take a ready-made one. When the first preparations are made, proceed to the main stages of manufacturing the concrete mixer .
They take an old barrel, clean it of debris, check the container for strength and the presence of holes or cracks . This must be done in order to assess the possibility of preparing a cement mixture in it. It is known that the solution is very heavy, and a rusty barrel will not withstand a regular load, so it is better to take a steel rather than an iron container.
Then the middle is measured and a hatch is cut out on the side surface of the barrel. It will be easier to get the ready-made solution from this hole. It is recommended to make the hole about 20-40 centimeters in size, depending on how much mixture you plan to prepare at a time .
After that, you need to attach the door to the finished hole. It can be made from a sheet of steel or iron that was previously cut from the container used to prepare the mixer. In order for the homemade door to close well, you need to attach rubber seals along the edges of the hatch using mounting glue. The metal sheet is easily fixed with two door hinges on one side and a latch on the other. If done correctly, then the cement will not fall out of the barrel prematurely .
When the drum is already done, it's time to start making the frame. You should not skimp on good reinforcement, it must withstand not only the steel container, but also the finished cement in the barrel. It is better to make 4 legs, connected to each other, on which the barrel will be held .
The drum will be set in motion with a handle, and rotation is provided by a driving shaft, which is attached to an already prepared barrel. It must be inserted inside, and in order to do this, you will have to drill holes on the sides.
Mounting flanges with bearings at the joints will help protect yourself from unnecessary damage during this procedure. They can be purchased at any hardware store, select the size according to the diameter of the axis used.
At the end, the manufactured elements should be connected together. The drive shaft should not be straight, but at a 30 degree angle. The barrel is attached to a previously welded frame and fixed well. If the reliability of the structure is in doubt, then it is better to dig the legs into the ground . You should not make the concrete mixer high, it is better if it is closer to the ground. These are the main stages in the manufacture of a manual concrete mixer. At home, you can make an electric concrete mixer, but this will require more materials and skills.
