Drilling a well today is quite expensive, which is why not everyone can afford such a pleasure at their summer cottage. The final price largely depends on the depth of the object. The larger this parameter, the more expensive such a source of clean and cold water will cost you. Nevertheless, a do-it-yourself drilling rig is made quite simply. Thus, you can make a well not only for yourself, but also earn some money. Let's talk about everything in order.
Classification of drilling rigs
Today, there are only 4 types of drilling rigs that are used in one way or another. Some of them are more popular, others less. For example, an installation operating according to the shock-rope principle of operation is the easiest to manufacture. In fact, this is a triangular-shaped frame to which a cable and bailer are attached.
More popular screwinstallation. The screw is used as a working part throughout the process. It is noteworthy that the bore hole is not washed with water during drilling.
Rotary units are even more difficult to manufacture. They work on the principle of hydraulic drilling, which already complicates the design. There is also a rotary manual hydraulic drilling rig. It is relatively easy to make such a unit with your own hands, we will talk about this a little lower.
On the benefits of homemade installations
Of course, there are a lot of advantages of a self-assembled drilling rig. First, it is cost savings. Of course, you will have to buy some components, but this does not compare in price with ready-made equipment. In any case, you will keep approximately 40-50% of your assets and gain experience in the process. Secondly, a homemade drilling rig will have the same technical characteristics as a factory-type product. This is a rather important point, since you can assemble a completely productive device. Typically, the weight of the unit is relatively light, and it can be quickly dismantled and reassembled. Along with decent mobility, this will allow you to drill wells even in the most inaccessible areas. As you can see, at least take away the merits. Let's move on to the practical part and talk directly about the assembly.
What do you need to get started?
Naturally, just taking and making a drilling rig will not work. To do this, you first need to prepare. It is desirable that toAt the time of assembly, you had minimal experience with welding. This will greatly facilitate your life, since you will not need to involve specialists or acquaintances. Also at hand should be an electric drill and a grinder. Why all this is needed, we will consider a little later.
But this is not the whole list of tools. It will be difficult for you to do without a device for creating an external thread, as well as an adjustable wrench and a plumbing cross. As a material, we need a galvanized pipe and a ½ inch drive. A special coating in our case is necessary, since if there is no zinc, the pipe will quickly rust. There is nothing good in this, since replacing it is a very problematic task. Well, now let's move on to the practical part of this article.
First phase of assembly work
At the very beginning, we need to prepare the pipe sections of the drilling rig, which are its main part. Their connection is realized by means of drives and crosses. To avoid any problems, a 2-centimeter external thread is provided at the ends of each pipe section. A metal plate is welded to two segments, it will be a tip. Such an installation will be effective only if water is constantly supplied to the drilling site. This will remove the soil, and thereby gradually deepen the hole. To supply water, you can use a regular hose that connects to the hole in the cross blank. In priority, the connection should be made usingsuitable adapter. Now let's move on.
Do-it-yourself mini-drilling rig: we continue to work
At this stage, you should deal with threaded connections. It is necessary to ensure that they are durable, since the duration of the operation of the drilling rig depends on this. The equipped tip should be connected to the lower end of the pipe, that is, to the one that will be in direct contact with the surface to be treated. The connection should be made with the help of a drive.
You should have a few tips handy. This is necessary so that in the process of work they can be changed. That is, at the very beginning of drilling, the shortest one is used, and after we get a hole 1 meter deep, we set a longer one. At the same time, you must understand that the length of the tip and the workpiece are different. Drilling is carried out by rotating the working unit. The sharp tip and water will do the rest of the work for you. In general, this stage is quite simple, the main thing is that the connections are of high quality and the tips are strong. By the way, the latter must be changed periodically, as they will break, become dull, etc.
How to make a DIY drilling rig?
We have already done about half of the work. But then there were the most responsible and important stages. The basis of the drilling structure is assembled from a square section profile. By and large, thisrack with the constituent elements of our design. To connect the supports to the racks, you must use the transition platform. It is quite natural that in this case it is problematic to do without welding. If you can, then cook yourself, if not, call someone who will do it well.
Platform and motor attached to a square profile. The latter is mounted on a rack in such a way that it can move along it, that is, pivotally along the guides. It is desirable that the dimensions of the profile at least slightly exceed the dimensions of the rack. Any small-sized drilling rig, made by hand, must have a suitable electric motor or gasoline engine. Regardless of the type of power element, its power must be at least 0.5 liters. with. This will be quite enough for the drilling process to proceed normally. It is desirable that it be possible to adjust the power; for this, an intermediate shaft must be installed between the engine and the working body.
Completing work
Now we turn on the water. Please note that it must be fed to the drill during the entire period of work. If this simple rule is not observed, then drilling efficiency will decrease significantly. High-performance drilling rigs with a high number of revolutions often imply the presence of water cooling. In our case, this is not necessary at all, but it is necessary to remove the soil from the well in any case. If you follow all the above rules, then everything will be fine.well. In any case, homemade drilling rigs require care and periodic maintenance. With your own hands you will repair them, change the tip, change the lubricant in the gearbox, etc.
Conclusion
Currently, there are a huge number of varieties of home-made rigs for drilling wells. Some of them are really good and have high efficiency, the design of others leaves much to be desired. For example, if you decide to make a drilling rig with a cartridge, then the weight of the latter should be as large as possible. This is due to the fact that it is they who will carry out drilling. As a blank, you can take a pipe with a diameter of 10-12 cm and a length of 10-20 cm. This should be sufficient for efficient operation.
Now you know how to make a drilling rig with your own hands. During the assembly process, it is desirable to use popular drawings, which will allow you to observe the dimensions and design features. Your homemade drilling rig will be as good as any factory rig, and maybe even better.
