Preferably, the immersion depth 34 is selected to be greater than the saw depth 35 from the seed 36 which is described in more detail in Fig. 5.

Figur 6 visar hur ett nedmyllningsorgan 14 bestgr av 10 en p5 fj5derarmen 21 fgstad roterbar skivbill 37, som pressas ned i jorden och utformar en skgra I denna. Till fjaderarmen 21 och skivbillen 37 Hr. en bill 38 fOr godningsamne f8rbunden. Via en tillfOrselledning 39 fores g6dningsmedel 11 ned till en Oppning 40 i nedersta delen 41 av billen 15 38. Nederdelen 41 16per i den av skivbillen 37 upptagna fgran. enom en delvis visad installningsanordning 42 kan man stalla in billens 38 lage i sid-ochhOldled relativt skivbillen 37, Harigenom kan forslitning av billarna kompenseras sA, att den upptagna fgran i jorden och nedmyllnings- 20 djupet blir de Onskade. Figure 6 shows how a mulching means 14 consists of A pivot arm 37 is provided on a spring arm 21 which is pressed into the ground and forms a shear therein. To the spring arm 21 and the disc beetle 37 Hr. a bill 38 fOr godningsamne f8rbunden. Via a supply line 39, fertilizer 11 is passed down to an opening 40 in the lower part 41 of the beetle. 38. The lower part 41 16per in the spruce occupied by the disc beetle 37. By means of a partially shown installation device 42, the position of the beetle 38 can be set in the lateral and lateral direction relative to the disc beetle 37, whereby wear of the beetles can be compensated so that the absorbed grain in the soil and the mulching 20 deep they become Injured.

Piguren visar hur fOrskjutning kan ske i sidled genom att lossa bultarna 42 och fOrskjuta billen 38 i sidled relativt det hus, i vilket bultarna 5r igangade, genom fOrskjutning i de visade aviAnga spAren i fastplAten. Genom en mot- 25 svarande anordning kan man stalla in det relativa hojdlgget mellan bill 38 och skivbill 37. The figure shows how displacement can take place laterally by loosening the bolts 42 and displacing the beetle 38 laterally relative to the housing in which the bolts 5 are engaged, by displacing in the shown different grooves in the fixed plate. Through a counter- Corresponding device, the relative height of the wedge 38 and the disc wedge 37 can be adjusted.

Figur 7 visar behgllaren 10 med g6dningsmedel 11 och pgfyllningsror 30. 43 betecknar utloppsledningen frn behgllaren 10 till en vatskepump 44, som styr g6dningsmedlets 30 utflode i matningsledningen 45 som funktion av en vridningsrOrelse 46. VridningsrOrelsen kan t ex utg6ras av en rotationsrorelse med konstant varvtal eller en rotationsroreise, vars vridningsvinkel ar proportionell mot den stracka, som redskapet tillryggalagger. Detta senare kan gstadkommas 35 genom att rotationsr6relsen erhglles fran ett med marken ingripande roterbart organ, t ex ett p5 en sektion anbragt 6 och pg marken rullande hjul, sa soin schematiskt angivits med 47 i figuren. Figure 7 shows the container 10 with fertilizer 11 and filling pipes 30. 43 denotes the outlet line from the container 10 to a liquid pump 44, which controls the fertilizer Outflow in the feed line 45 as a function of a rotational movement 46. The rotational movement can for instance be constituted by a rotational movement with constant speed or a rotational rudder travel, the angle of rotation of which is proportional to the distance traveled by the implement. This later can be achieved In that the rotational movement is obtained from a rotatable member engaging with the ground, for example a section arranged on a section 6 and pg ground rolling wheels, so soin is schematically indicated by 47 in the figure.

Ngr man vander kombinationsredskapet pa en vandteg lyfter man under vandningen redskapets sektioner frin arbets- lgge till vile- ellertransportlgge enligt vad son visas i figur 2. Harvid lyftes aven hjulet 47 upp och rotationsrorelsen 46 upph8r, d v s utflOdet av gOdningsmedel avbrytes. Detta kan gven gstadkommas av en avstangningsventil, son aven den styres av redskapets omstgllningsrorelse sa, att utflOdet av godningsmedel stanges ay. When watering the combination tool on a watertight, during the watering, lift the tool sections from the work surface. add to vile- or transport transport according to what son is shown in figure 2. At this the wheel 47 is also lifted up and the rotational movement 46 ceases, i.e. the outflow of fertilizer is interrupted. This can also be provided by a shut-off valve, which is also controlled by the gear changing movement of the tool, so that the effluent of sweetener is stang ay.

Frgn pumpen 44 ledes den avpassade mgngden g8dningsmedel genom matningsledningen 45 till billarnas 38 tillforselledningar 39 ochtill de f8rut beskrivna utlopps8ppningarna 40. From the pump 44, the appropriate amount of fertilizer is passed through the supply line 45 to the supply lines 39 of the cars 38 and to the outlet openings previously described. 40.

Vanligen gr gbdningsmedlet hygroskopiskt och drager darfor till sig vatten sg att fuktigheten pa nedmyllningsdjupet 34 Okar. Detta medfor att mar rotsystemet pa utsadet 36 utvecklas, kommer rottradarna att sake sig nedat fran sgdjupet 35 och utveckla sig pi ett mycket gynnsamt sgtt. Usually the fertilizer is hygroscopic and pulls therefore absorb water so that the humidity at the depth of soiling 34 Increases. This means that as the root system on the seed 36 develops, the root rows will sink down from the saw depth 35 and develop in a very favorable way.

Detta at- en stor fOrdel vid t ex h8stsadda gr8dor efter dessas 8vervintring och vid varsadda grodor i omraden, som kan drabbas av forsommartorka. This is a great advantage for, for example, harvested crops after their 8wintering and at warned frogs in the areas, which may be affected by early summer drought.

Ehuru dot utf8rande av kombinationsredskapet enligt uppfinningen, som beskrivits oven i samband med ritningarna, ar ett foredraget utfOrande av uppfinningen kan denna modifi- eras pg olika sg.tt utan att uppfinningstanken frgnggs.
