Build through sieve yourself - instructions: sieve

A transfer screen is a useful tool to remove the coarse particles, such as fruit pits from your own compost. The compost provides a good soil because it is enriched with all the important nutrients. The Durchwurfsieb can be built in some steps by yourself. For this purpose, in addition to the materials that can be found in every hardware store, also some tools needed.

material

To build a transfer screen, a screen mesh is needed. For this purpose, a galvanized steel mesh can be used. Optimal is a size of 2000 x 1000 cm. The width of the mesh depends on the individual purpose of the earth. Tip: A mesh size of 1.5 cm ensures a good particle size. Smaller meshes tend to blockage easily. The grille can be installed in an existing support frame. For this purpose, it must be adapted to the dimensions of the frame. If you do not have a frame, you can weld yourself a frame yourself. These materials are needed for the wearer:
  • 2 angle irons measuring 2000 x 20 x 5
  • 2 angle iron measuring 1000 x 20 x 5
  • 2 T-ones with the dimensions 1000 x 20 x 5.
Alternatively, however, scantlings in the dimensions of the steel grid are sufficient. To connect these, screws and hooks are needed. The through-sieve of this size is optimally suited to catch the earth with a wheelbarrow. The collection is also possible with a foil. Ideally, legs are attached to the screen so that it can stand free. For this purpose, two square timbers with a size of 1.80 m to 2.00 m and two hinges are required for fixing.

Cutting and assembly

All four angle irons are cut to a miter. This means that the edges are sawn off at a 45° angle. As a result, the parts can be mounted together so that there is a 90° angle between two angle irons. If squared timbers are used for the girder frame, they can also be mitred. After the angle irons have been cut, they can be welded together to form a rectangle. Tip: In the first step, the angle iron should be welded together at certain points. Once the angles have been checked to their correct dimensions, they can be completely welded.
To check the angle, an angle gauge can be used. This is inserted in the corners of the frame. If there are no gaps between the frame and protractor, then the corner angles have a dimension of 90°. The measurement of the diagonals also shows whether the edges were neatly cut. Who wants to use a support frame made of squared timbers, who can screw the woods together. Again, the items are first placed together so that forms a correct right angle. Subsequently, a marker is set with a pencil, to which the screw is to be set. The marking should be recorded so that the screw passes through the long side of a square timber and connects it to the cut edge of the second square timber. Here it should be ensured that the screw is placed as centrally as possible.

Installation of the steel grille

The steel grid is now also welded to the frame at points. This allows corrections to be made if the grid has not been installed correctly. Then it can be welded to the entire bearing surface. If a support frame made of square timbers was used, then the steel grid can be fastened with the help of hooks on the entire surface. The disadvantage of the squared screen from squared timbers is that the material must be protected against weathering and external environmental influences. For this, the squared lumber should be liberally painted with a wood varnish. This penetrates deep into the grain and thus protects the wood from penetrating moisture. The paint must be renewed regularly. Otherwise, the material may swell, splitting and breaking after some time.

stability

compost

The through sieve with the steel girder is already more stable than a sieve with squared lumber. With the T-irons, which are attached as cross connections, the sieve gets additional stability. As a result, it is still stable even with large amounts of soil. If the T-woods already have the dimensions of the wide side of the frame, they can be placed in the middle and welded together at the two ends with the frame. If the irons are longer, they must be cut to the correct length. In order to make the squared lumber stable, a second wooden frame is suitable. This must have the same dimensions as the first frame. With the help of holes, the second frame is connected to the support frame. The intervening grid is thus kept taut and the entire frame is more stable. In order for the sieve to be set up, the two squared timbers still have to be mounted. The hinges are attached to the upper corners of the support frame and then screwed to the squared lumber. Thus, the sieve can be stowed to save space.

frequently asked Questions

  • For which earth is the through-sieve suitable?
The sieve with a mesh size of 1.5 cm is suitable for the compost, to which no sand or gravel was added. These particles have a smaller grain size and would fall through the screen. To sieve such particles out of the soil, a smaller mesh size should be used. However, there is a risk that the screen clogged quickly.
  • Can I also use metal woods as legs?
Yes, that is possible. Here, however, the attachment is a bit more expensive, because it requires a steel drill, so that the hinges can be attached to the individual parts. This also increases the material costs.
  • How can I cut the steel parts?
With a chainsaw the best results are achieved. The material can also be cut with a Flex or a water steel cutter. Such instruments can be borrowed at many hardware stores.
  • How do I get a perfect miter?
A miter can be cut by markers. To cut a precise angle, a miter box is used. Typically, this can be used to cut 45° angles, which are assembled at a 90° angle. Alternatively, there are also manually adjustable miter. Here the angle to be cut can be set by yourself.

Worth knowing about throw-through thieves soon

A transfer sieve is necessary for compost preparation in the garden. Compost can be easily made from garden waste. However, to get a good and even compost, garden waste rots rather unevenly, it is imperative if you throw it through a thief.
characteristics
The ideal through-sieve is made of stainless material. Best of a galvanized metal, so that neither humid weather conditions, still damp compost can affect the Durchwurfsieb in the long run something. The field of application of the Durchwurfsieb is not limited to the garden area. Even on construction sites, the through-sieve finds its application area.
The ideal through-sieve consists of a grid, which is set in a metal frame and ideally it is adjustable by means of a support. The cheapest or most ideal mesh size is a grid of 40/15 millimeters. The screening surface should at least be made of expanded metal and enclosed in a stable angular enclosure, which was produced entirely by hot-dip galvanizing.
  • A recommended size for a transfer screen is a length from 100 to 60 cm in width.
  • However, a larger garden in which a larger compost silo or multiple compost silos are installed also requires a larger throughput screen.
  • Passing sieves are with the mentioned characteristics costs in trade around the 25 euro.
Conclusion
It is not absolutely necessary to use a transfer sieve for composting only to ensure that the self-produced humus used in the garden has a uniform and fine texture. Even if you work in the garden during the garden year, it can quite often happen that a thief sieve can be used. Especially in spring, when beds are laid out and the seed comes into the field. If one uses the Durchwurfsieb to that one the earth of the beds with this sieves, one obtains finest Beeterde. Can mix the bedding with humus in one operation and at the same time the earth is enriched with oxygen.
