Opfindelsen angår en markør af den art, som er angivet i krav 1's indledning.The invention relates to a marker of the kind set forth in the preamble of claim 1.
Fra tysk offentliggørelsesskrift nr. 32 42 932 kendes en mar-5 kør af nævnte art. Denne markør er ved hjælp af et kardanled hængslet til landbrugsmaskinens ramme. Yderligere er der på markøren anbragt et spændeelement, som holder markøren i dennes forud fastlagte driftsstilling. På grund af dens hængsling og fastgørelse, kan markøren, når den støder på forhindringer, 10 undvige skråt bagud og opad.German Patent Publication No. 32 42 932 discloses a mar-5 driver of the said kind. This marker is hinged to the frame of the agricultural machine by means of a cardan joint. Further, a clamping element is provided on the marker which holds the cursor in its predetermined operating position. Due to its hinging and attachment, when it encounters obstacles, the cursor can dodge backwards and upwards.
Ulempen ved denne kendte markør er især de relative store fremstillingsomkostninger, hvorfor denne udformning er meget dyr. Yderligere vil markøren blive beskadiget, når forhindrin-15 gen, som markøren støder mod, rammer ovenover omdrejningsaksen for markørens skive.' Da markørens skive i disse tilfælde vil køre ned under forhindringen, kan markøren ikke undvige skråt bagud og opad. Derfor vil der uundgåeligt opstå skader på markøren.The disadvantage of this known marker is in particular the relatively large manufacturing costs, which is why this design is very expensive. Further, the cursor will be damaged when the obstacle encountered by the cursor strikes above the axis of rotation of the cursor disc. ' Since in these cases the cursor's disc will run down the obstacle, the cursor cannot dodge backwards and upwards. Therefore, damage to the cursor will inevitably occur.

Formålet med opfindelsen er, at anvise en simpel og billig beskyttelsesmulighed for markører.The object of the invention is to provide a simple and inexpensive protection option for markers.
Til opnåelse af dette formål er markøren ifølge opfindelsen 25 ejendommelig ved de i krav 1 anførte kendetegnende træk. Herved opnåes, at markøren ved hjælp af beskyttelseselementet bliver hævet op over den aktuelle forhindring. Beskyttelseselementet kommer foran markørens skive i berøring med forhindringen. Beskyttelseselementet virker overfor skiven, og ovenover den-30 nes omdrejningsakse, som en mede, hvorved skiven også bliver hævet op over forhindringer, som ellers ville ramme markørens skive ovenover skivens omdrejningsakse. Ved en passende udformning af beskyttelseselementet, kan man fastlægge op til hvilke størrelser af forhindringer, beskyttelseselementet skal 35 være virksomt, således at markøren så vidt muligt ubeskadiget kan undvige alle forhindringer. Det er muligt at anbringe flere beskyttelseselementer ovenover hinanden. Ligeledes kan der 2To achieve this purpose, the marker according to the invention 25 is characterized by the characteristic features of claim 1. This results in the cursor being raised above the current obstacle by means of the protective element. The protective element comes into contact with the obstacle in front of the marker's disc. The protective element acts opposite the disc and above its axis of rotation, as a means whereby the disc is also raised above obstacles which would otherwise hit the disc of the cursor above the axis of rotation of the disc. By an appropriate design of the protective element, it is possible to determine up to what sizes of obstacles, the protective element must be effective, so that the cursor can avoid all obstacles as far as possible undamaged. It is possible to place several protective elements on top of each other. Similarly, 2

benyttes forskelligt udformede beskyttelseselementer, som i afhængighed af den aktuelle brugssituation ved hjælp af hur-tigspændeanordninger, kan fastgøres til markørens arm henholdsvis udskiftes.variously designed protective elements are used which, depending on the current use situation by means of quick-release devices, can be attached to the cursor arm or replaced.

Ifølge opfindelsen kan beskyttelseselementets underste kant i markørens driftstilling tilnærmelsesvis befinde sig under en vandret gennem skivens omdrejningsakse forløbende linie. Herved sikres det, at skiven i ethvert tilfælde bliver ført op 10 over forhindringer, såsom store sten, som ligger på jordoverfladen, tværfurer på jordoverfladen, eller fordybninger ved særlig høje plovfurer. Beskyttelseselementet forhindrer, at skiven ovenover dennes omdrejningsakse kommer i berøring med forhindringer.According to the invention, the lower edge of the protective element in the cursor operating position can be approximately below a horizontal line extending through the rotational axis of the disc. This ensures that the disk is in any case raised 10 over obstacles, such as large stones lying on the ground surface, cross-grooves on the ground surface, or recesses at particularly high plow furrows. The protective element prevents the disk above its axis of rotation from coming into contact with obstacles.

Desuden kan ifølge opfindelsen beskyttelseselementet have en i markørens driftstilling fra skiven skråt opad og skråt fremad i retning mod drejeleddet henholdsvis maskinens midte forløbende kant eller mede. Herved opnåes en beskyttelse af hele 20 markøren inklusive armen, idet beskyttelseselementet tillige i det mindste delvis befinder sig foran armen, og derved også hæver armen op over forhindringen. En særlig god beskyttelse af skiven opnåes ifølge opfindelsen ved, at beskyttelseselementet delvis omslutter skivens forside.In addition, according to the invention, the protective element may have an upward and inclined forward direction in the cursor operating position from the disc towards the pivot joint and the center extending or middle of the machine, respectively. This provides protection for the entire marker including the arm, the protective element also being at least partially in front of the arm, thereby also raising the arm above the obstacle. Particularly good protection of the disc is achieved according to the invention in that the protective element partially encloses the front of the disc.

10 På såmaskinen 1, er der på begge rammens 2 ydre sider anbragt en markør 3, som ved hjælp af et drejeled 4, kan svinge i et lodret plan. Markøren 3 kan herved hæves og sænkes ved en drejning omkring i køreretningen, og gennem hver af drejeled-15 dene 4 forløbende svingakser 5. En markøro.mskifter 6 er an bragt på såmaskinens ramme 2. Mellem markørerne 3 og markøromskifteren 6, er der anbragt kæder 7, ved hjælp af hvilke, markørerne 3 ved markenderne skiftevis kan hæves i ikke-drifts-stillingen, og sænkes i driftsstillingen.10 On the seed drill 1, on the outer sides of both frame 2 is arranged a marker 3 which can swing in a vertical plane by means of a swivel joint 4. The cursor 3 can thereby be raised and lowered by a rotation about in the direction of travel, and through each axis of the rotary joints 4 rotating axes 5. A marker switch 6 is placed on the frame of the seed drill 2. Between the markers 3 and the cursor switch 6 are arranged. chains 7, by means of which the markers 3 at the markets can be alternately raised in the non-operating position and lowered in the operating position.

Hver markør 3 er forsynet med en arm 8 og en skive 9, som ved enden 10 af armen 8, er frit drejeligt lejret ved hjælp af et leje. Set i køreretningen 11, er der foran markørens 3 arm 8 anbragt et beskyttelseselement 12. Dette beskyttelseselement 25 12, der er udformet som en bøjle 13, rager set i køreretningen 11 ud foran skiven 9. Bøjlens 13 underste kant 14 befinder sig i markørens 3 driftsstilling, nedenunder en vandret gennem skivens omdrejningsakse 15 forløbende linie 16. Yderligere forløber bøjlens 13 forreste kant i markørens 3 driftsstiΠing 30 fra skiven 9 skråt opad og skråt fremad i retningen mod dreje-leddet 4 henholdsvis maskinens midte. Denne forreste kant 14 virker i praksis som en mede, når bøjlen 13 støder på en forhindring. 1 Når markøren 3 støder på en forhindring 19 på marken 18, hæver bøjlen 13 markøren.hen over forhindringen 19 henholdsvis hæver skiven 9 så meget, at den nedre skrå halvdel 20 af skiven 9Each marker 3 is provided with an arm 8 and a disc 9 which, at the end 10 of the arm 8, are freely pivotally supported by a bearing. Seen in the driving direction 11, a guard element 12 is arranged in front of the arm 8 of the marker 3. This protective element 25 12, which is formed as a hanger 13, protrudes in the driving direction 11 out in front of the disc 9. The lower edge 14 of the hanger 13 is in the cursor 3. operating position, below which is a horizontal line extending through the rotary axis 15 of the disc 15. Further, the leading edge of the bracket 13 extends in the operating position 30 of the marker 3 from the disc 9 inclined upwards and inclined forwards in the direction of the pivot joint 4 and the center of the machine respectively. In practice, this leading edge 14 acts as a joint when the hoop 13 encounters an obstacle. 1 When the cursor 3 encounters an obstacle 19 on the field 18, the hoop 13 raises the cursor. Over the obstacle 19, respectively, the disc 9 raises so much that the lower inclined half 20 of the disc 9

4 støder mod forhindringen 19, og skiven 9 derved ubeskadiget kan rulle hen over forhindringen 19. Beskyttelsesbøjlens 13 skrå forreste kant 17 forhindrer ligeledes, at skiven 9 ovenover skivens midte eller skivens omdrejningsakse 15 kommer i 5 berøring med forhindri ngen 19. Under normal drift er bøjlen 13 ikke i berøring med marken, men befinder sig i en lille afstand A fra jordoverfladen 18. Hermed forhindres det, at bøjlen 13 danner jordvolde foran sig.4 abuts the obstacle 19 and the disc 9 can thereby undamaged roll over the obstacle 19. The inclined leading edge 17 of the protective bracket 13 also prevents the disc 9 above the center of the disc or the axis of rotation 15 from contacting the obstacle 19. During normal operation, the shackle 13 is not in contact with the field, but is at a small distance A from the ground surface 18. This prevents the shackle 13 from forming ground walls in front of it.
10 Den i fig. 5 til 7 viste udførelsesform for bøjlen 21, er udformet på en lidt anden måde end bøjlen 13. Den som beskyttelseselement udformede bøjle 21, er fastgjort til markørens 3 arm 8. Bøjlen 21 rager set i køreretningen 11 ud foran skiven 9. Den underste kant 22 af bøjlen befinder sig i markørens 15 dr iftssti11ing nedenunder den vandret gennem skivens omdrej ningsakse 15 forløbende linie 16. Yderligere forløber den forreste kant 23 af bøjlen 21 i markørens 3 driftssti 11 ing fra skiven 9 skråt opad og skråt fremad i retning mod drejeleddet 4 henholdsvis maskinens midte. Denne forreste kant 23 virker i 20 praksis som en mede, når bøjlen 21 støder på en forhindring. Bøjlen 21 omslutter delvis skivens 9 forside 24 og rager i udadgående retning et kort stykke 25 ind over skiven 9.10 The embodiment of FIG. 5 to 7, the bracket 21 is configured in a slightly different way from the bracket 13. The bracket 21, which is designed as a protective element, is attached to the arm 8 of the marker 3. The bracket 21 extends in the direction of travel 11 in front of the disc 9. The lower edge 22 of the bracket is in the position of the cursor 15 below the horizontal line extending horizontally through the rotary axis 15 of the disc 15. Further, the leading edge 23 of the bracket 21 in the operating path 11 of the cursor 3 extends upwardly and inclined forwardly towards the pivot joint 4. respectively the center of the machine. In practice, this leading edge 23 acts as a joint when the hoop 21 encounters an obstacle. The bracket 21 partially encloses the front face 24 of the disc 9 and projects outwardly a short distance 25 over the disc 9.
Bøjlen 21 fungerer på følgende måde: 25 Når såmaskinen benyttes på -plane marker, har bøjlen 21 ikke berøring med jorden. Befinder der sig imidlertid på jordoverfladen 18 forhindringer 19, i form af store sten eller grove, store knolde eller forhindringer i form af dybe tværfurer el-30 ler dybe furer i form af grove plovfurer, bliver skiven 9 henholdsvis armen 8 hævet op over disse forhindringer 19, inden skiven 9 ovenover dennes omdrejningsakse 15 kan komme i berøring med forhindringen. Den forreste skrå kant 23 af bøjlen 21 løber opad på forhindringen 19. Forhindringen 19 glider forbi 35 kanten 23, og hæver på grund af kantens 23 skrå forløb skriven 9 henholdsvis markørens 3 arm 8. Skiven 9 bliver ved hjælp af bøjlen 21 ved påløbet på forhindringen 19 hævet så meget, atThe bracket 21 works as follows: 25 When the seed drill is used on flat planes, the bracket 21 does not touch the ground. However, if there are obstacles 19 on the ground surface 18, in the form of large stones or coarse, large tubers or obstacles in the form of deep cross furrows or deep furrows in the form of coarse plow furrows, the disc 9 and arm 8 are raised above these obstacles, respectively. 19 before the disc 9 above its axis of rotation 15 can come into contact with the obstacle. The front oblique edge 23 of the hoop 21 runs upwardly on the obstacle 19. The obstacle 19 slides past the 35 edge 23 and, due to the oblique course of the edge 23, raises the writing 9 and the arm 3 of the cursor 8, respectively. the obstacle 19 raised so much that
