Screw for earth drilling: manufacturing

Screw for drilling earth may be needed in thosecases where there is a need to delve into soft soils. The tool for this can be made independently. The maximum depth of the trunk is 20 m.

Design features

One of the parts of this design stands outA drilled split pipe, the length of which can be increased when buried. As one of the most important elements is the handle, with which you can rotate the tube yourself or with the help of a second person. If you decide to make a screw to drill the earth, it is important to provide it with a working part that can be made in several ways. It is important to prepare a fairly thick metal, as well as welding equipment.

Manufacture of a spiral type drill

If you decide to make an auger yourselfdrilling of the earth, it is possible to perform it in the form of a spiral design. In the basis there will be a metal core, at which the end is sharpened. Two knives should be welded to the tip with a tip so that their edges are removed from the base by 200 millimeters. To perform work on the formation of knives, you should prepare 1/2 part of the steel disc, the thickness of which can vary from 100 to 150 millimeters. Making a screw to drill the earth, it is important to weld the knives to the steel rod in such a way that the elements are located under a slight slope, the value of the latter should be 20 degrees to the horizontal surface.

The halves of the metal disc mustopposite each other. In the end, the angle between the fixed knives should be 40 degrees. The lower edges of the working elements of such a drill must be sharpened well before use. On how sharp the knives will be, the lightness and speed of the tool's entry into the soil will depend. If we compare this device with the industrial model, then it can be noted that the last band began to initially heat up to the required temperature, and after being twisted into a spiral. The distance between the turns is equal to their diameter. Once the steel is twisted, it is hardened.

Features of making a drill under the water

If you decide to make a screw to drill the earth,The photo of this tool is recommended to be considered even before the beginning of the work. This will allow us to understand what constructive features a tool has. To make the handle, you can use a pipe, which is based on metal. The cross section of this blank should be three centimeters, but no more. If such a pipe is not available, wood can be used to make the handle. The drill can also be made of steel strip. At the rear end of the strip, it is necessary to form a hole for the handle, while a tip in the form of a loop is fixed at the working end. At the moment of rotation of the drill in the soil, the tip absorbs a certain amount of soil, which is then removed with the tool on the surface. At the next stage, the entire procedure is repeated. A well of the required depth will be obtained by joining several strips and rotating the structure.

Manufacturing technology

A screwdriver for 50mm ground drilling will be obtained ifUse a steel strip whose length is 0.5 meters. Its width can be chosen independently, using the limit of 5 to 10 cm. For the tool, you can use steel 1 cm thick. From the end of the strip, retreat 8 cm, and then make a hole in the form of a slot. The size of the latter should be 150x2 millimeters.

When a screw is made for drilling earthmanual, the rear end of the drill must be bent so that a ring is obtained to install the handle in the form of a lever. At the working end, the steel strip on the sides should be unbent in opposite directions to form an oval. In the tip area, the metal strip must be cut off to form a point. It should be sharpened and the sides bent in the opposite direction. A handle is inserted into the ring on the back of the tool, which gives the screw a rotational motion. With the help of such equipment it will be easy to do a well not only in sandy soil, but also in loams, in which there are gravel inclusions.

Manufacture of spoon type auger

If you decide to make a screw to drill the earthown hands, then the basis of the design can lie a spoonful version of the instrument. The device will look like a cylinder made of metal. On the equipment you need to make a slot that has a spiral or longitudinal shape. The working tip of the device should be a ladle made of metal sheet. Among other things, this part can be formed from a longitudinally cut tube blank. The process of rotation of the screw will destroy and absorb the soil with the help of the tip and slits that are located in the cylinder. In order to improve penetration, a metal drill with a significant diameter should be welded to the bottom.

Conclusion

The axis of rotation and the axis of the drill of the whole structure mustcoincide, whereas the cylinder with cutting edges should be displaced relative to the axis of the device by 1.5 cm. Eventually, the cylinder will move with eccentricity and cut the soil from the walls of the well, forming a well of a more impressive diameter than the screw itself.
