Description

Oppfinninga gjeld ein anordning av det slaget som er definert i innleiinga til patentkrav 1, for å leggje press på silomasse, særlig i tårnsiloar. The invention relates to a device of the kind defined in the introduction to patent claim 1, for putting pressure on silo mass, particularly in tower silos.

Ensilering av stråfor i tårnsiloar har vore vanleg i omlag 30 år. Gjennom denne tida er det gjort mange forsøk på å finne høveleg og lettbrukt utstyr for å leggje press på silomassen. Silage of straw forage in tower silos has been common for around 30 years. Throughout this time, many attempts have been made to find suitable and easy-to-use equipment to put pressure on the silo mass.

Alt i 1957 kom det forslag om å bruke ein vasstett pressduk i form av eit kar som skulle leggjast på toppen av silomassen og fyllast med vatn. For å halde karsidene oppe, vart det i tysk patentskrift 1.000.176 foreslege å bruke vertikale utvendige rør. Som støtte for desse røra vart det brukt BkrÅBtrever innover mot festepunkt på kargolvet. Men denne løysinga av pressproblemet kravde mange element og koplisert montering og er derfor ikke vorten utnytta i praksis. All the way back in 1957, there was a proposal to use a watertight press cloth in the form of a vessel which was to be placed on top of the silo mass and filled with water. In order to keep the tank sides up, it was suggested in German patent document 1,000,176 to use vertical external tubes. As support for these pipes, BkrÅB trever was used inwards towards the attachment point on the cargo floor. But this solution to the pressure problem required many elements and complicated assembly and has therefore not been used in practice.

Hovedformålet med oppfinninga er derfor å skape ei pressanordning som er enklare både i utforming og bruk. The main purpose of the invention is therefore to create a pressing device that is simpler in both design and use.

Med utgangspunkt i det kjende er oppfinninga definert i den karakteriserande delen av patentkravet. Based on what is known, the invention is defined in the characterizing part of the patent claim.

I figuren er det vist eit diametralt vertikalsnitt gjennom ein silo der ei anordning i samsvar med oppfinninga er brukt. The figure shows a diametrical vertical section through a silo where a device in accordance with the invention is used.

I tegninga er siloveggen vist ved 1 og silomassen ved 2. Ein duk 3 er lagt på toppen av silomassen slik at den dekkjer denne og dessutan strekkjer seg eit stykke oppetter den fri veggsida som vist ved 4. Duken, er tilverka av tekstil som er In the drawing, the silo wall is shown at 1 and the silo mass at 2. A cloth 3 is placed on top of the silo mass so that it covers it and then extends a little way up the free side of the wall as shown at 4. The cloth is made of textile that is

Claims

plastic coated or a similar waterproof and mechanically strong material. The canvas shape is adapted to the opening in the silo and has a circular or rectangular/square bottom with side walls.

In order to keep the fabric side 4 up along the silo wall, in accordance with the invention, a row of hooks 5 is attached along the edge of the press cloth and a corresponding row of hooks 6 approximately one meter in from the edge, along a line corresponding to the silo shape. The hooks 5, 6 are in the example made of plastic or rubber and attached to the cloth either by gluing or heat treatment. As shown in the section on a larger scale, each hook has the shape of a J-knob 7, as these knobs face each other in pairs for hooks 5 and 6.

An elastic bendable rod 8, in the example in the form of a plastic tube, is inserted between two such pairs of hooks.

This device is unusually easy to use. After the canvas has been laid out in the usual way, it can easily be put on rods or shoes 8 around the edge, e.g. 10-20 scores. This only takes a short time and the rods 8 are easy to take up in the silo and later take out. After putting on the shoes, it can be filled with water 9 in the usual way. The shoes 8 will then hold the edge 4 of the cloth in place up behind the silo wall 1 at the same time as the entire cloth and the shoes 8 can slide along the silo wall as the fore mass is pressed together. This device does not create obstacles for other work on the silo, e.g. thatching, and does not require space for cords over the edge. Patent claim: Device for applying pressure to form mass (2) in a tower silo (1). with a water-tight pressing cloth (3) which is laid out on top of the form mass and has edges (4) which, when laid out, stretch up along the silo wall, for filling in water as pressing mass, and which is held up by means of braces that support themselves towards the inner horizontal area of the press cloth, characterized in that the struts are anchored to a fastening device (5) which is integrated with the edge of the press cloth.
