Opfindelsen angår en dyseholder til et landbrugssprøjteudstyr af den art, som er angivet i krav l's indledning.The invention relates to a nozzle holder for an agricultural spraying equipment of the kind set forth in the preamble of claim 1.

5 Der kendes fra det tyske brugsmønster nr. 82 03 649 en dyse holder af denne art. Denne dyseholder har et som en membranventil udformet tastningselement, som er fastholdt til huset ved hjælp af en møtrik. Det er en ulempe ved denne fastgørelse af tætningselementet, at der i dyseholderens hus må skæres et separat gevind til møtrikken. Yderligere er det ved nævnte fastgørelse af tætningselementet en ulempe, at møtrikken ikke kan frigøres og tætningselementerne derfor ikke udskiftes ved trange indbygningsforhold.5 A nozzle holder of this kind is known from German usage pattern no. 82 03 649. This nozzle holder has a sensing element designed as a diaphragm valve which is secured to the housing by means of a nut. It is a disadvantage of this fastening of the sealing element that a separate thread must be cut into the housing of the nozzle holder. Furthermore, in said attachment of the sealing element, it is a disadvantage that the nut cannot be released and therefore the sealing elements are not replaced under tight installation conditions.

I5 Formålet med opfindelsen er at anvise en dyseholder af den indledningsvis nævnte art, hvor fastgørelsen af tætningselementerne er væsentlig enklere og bedre.The object of the invention is to provide a nozzle holder of the kind mentioned above, where the attachment of the sealing elements is substantially simpler and better.

Dette opnås ved, at dyseholderen ifølge opfindelsen er ejen-2o dommelig ved de i krav 1 anførte kendetegnende træk. Herved opnås et pladsbesparende og let aftageligt låseorgan, som selv i dyseholderens indbyggede tilstand kan frigøres, således at tætningselementerne kan fjernes, rengøres eller udskiftes.This is achieved by the fact that the nozzle holder according to the invention is proprietary to the features of claim 1. This results in a space-saving and easily removable locking means which can be released even in the built-in condition of the nozzle holder, so that the sealing elements can be removed, cleaned or replaced.

25 For sikkert at kunne fastholde tætningselementerne i dysehol derens hus kan ifølge opfindelsen skyderen have flige, som indgriber i husets sporformede føringer.In order to be able to securely hold the sealing elements in the housing of the nozzle housing, according to the invention, the slider may have tabs which engage the track-shaped guides of the housing.

Endelig kan fligene og sporene stå lidt på skrå i forhold 30 til parallelt med skivens føringer forløbende linier. Herved udlignes bearbejdningsunøjagtigheder, og tætningselementerne holdes fastpresset mod hinanden.Finally, the tabs and grooves may be slightly inclined in relation to the lines extending parallel to the guides of the disc. This eliminates machining inaccuracies and keeps the sealing elements pressed together.

Yderligere fordelagtige udførelsesformer fremgår af de øvrige 35 underkrav og nedenfor, hvor opfindelsen forklares under hen visning til tegningen, og hvor 1 1 viser - set forfra - en udførelsesform for en dyse- 2Further advantageous embodiments are shown in the other subclaims and below, in which the invention is explained with reference to the drawing, and in which 1 shows - from the front - an embodiment of a nozzle.

En dyseholder kan fastgøres på kendt, og derfor ikke vist, måde på en marksprøjtes sprøjtefordelerrør ved hjælp af en ekspanderende spændestuds 42. På dyseholderens 1 overside er der anbragt to fastgørelsesstifter 3, der kan rage gennem 1Q sprøjtefordelerrørets ophængningsdel. Skulle den ekspanderende spændestuds 2 blive beskadiget, kan der gennem hver af fastgørelsesstifternes 3 huller 4 stikkes en sikringsstift, således at dyseholderen 1 atter sidder fast på sprøjtefordelerrøret.A nozzle holder can be secured in a known, and therefore not shown, manner on a field sprayer's spray manifold by means of an expanding clamp 42. On the upper side of the nozzle holder 1 are arranged two fastening pins 3 which can project through the suspension part of the spray distributor tube. Should the expanding clamp 2 be damaged, a securing pin may be inserted through each of the holes 4 of the fastening pins 3 so that the nozzle holder 1 is again secured to the syringe distributor tube.

Dyseholderen 1 har et hus 5, hvorpå der er anbragt en sprøjte-middeltilføringstilslutning 6, en yderligere tilslutning 7 til forbindelse med de andre dyseholdere og en dysetilslutning 8.

Kanalens 10 centerlinie 12 er anbragt under sprøjtemiddeltilføringstilslutnin-25 gens 6 centerlinie 13, medens dysetilslutningens 8 centerlinie 14 skærer sprøjtemiddeltilføringstilslutningens 6 centerlinie 13. Ringkammeret 11 omgiver kanalens 10 væg 15. Yderligere er ringkammeret 11 forbundet med dysetilslutningen 8, idet den underste del af ringkammeret 11 nemlig ved sidstnævntes 30 bagvæg 16 munder ud i dysetilslutningen 8.The nozzle holder 1 has a housing 5 on which is fitted a spray medium supply connection 6, a further connection 7 for connection with the other nozzle holders and a nozzle connection 8. In addition, the nozzle holder 1 has a diaphragm valve 9 which in connection between the spray medium supply connection 6 and the nozzle connection 8 forming a seal between a channel 10 and an annulus 11. The channel 10 is connected to the pesticide supply connection 6, the channel 10 opening to the side of the pesticide supply connection 6. The center line 12 of the channel 10 is positioned below the center line 13 of the spray medium supply connection 6, with the center line 13 of the pesticide supply connection 6. 14 intersects the spray line supply connection 6 center line 13. The ring chamber 11 surrounds the wall 15. of the channel 10. In addition, the ring chamber 11 is connected to the nozzle connection 8, the lower part of the ring chamber 11 opening at the nozzle connection 8 of the latter 30.

Membranventilen 9 befinder sig til siden for sprøjtemiddelti 1 førings til slutningen 6 og dysetilslutningen 8. Kammerets 11 ydervæg 17 udvider sig ved den mod membranventilens 9 mem-35 bran 18 vendende side, idet der dannes et ringformet trin 19 i et glat cylinderformet afsnit 20. Dette afsnit 20 indeholder en ringformet tætningsring 21, der med membranens 18 rand 22 som mellemlæg presses mod det ringformede trin 19 af 3The diaphragm valve 9 is located to the side of spray medium 1 guide to the end 6 and the nozzle connection 8. The outer wall 17 of the chamber 11 extends at the side 18 facing the membrane valve 9 of the diaphragm valve 9, forming an annular step 19 in a smooth cylindrical section 20.

Herved bliver huset 5 lukket/ således at sprøjtevæsken uden at lække kan ledes fra sprøjtemiddeltilføringstilslutningen 6 til dyse-5 tilslutningen 8. For at opnå en særlig god tætning har tæt ningsringen 21 på den mod membranen 18 vendende side 25 en rundtgående vulst 26.a locking member 24, which is formed as a slider 23. Hereby the housing 5 is closed / so that the spray liquid can be conducted without leaking from the spray medium supply connection 6 to the nozzle 5 connection 8. In order to obtain a particularly good seal, the sealing ring 21 on the the diaphragm 18 facing side 25 a circular bead 26

Inden i tætningsringen 21 er der anbragt en cylinderformet 2Q trykring 27, der trykkes mod membranen 18 af en fjeder 28, der støtter mod tætningsringen 21. Herved presses membranen 18 mod kanalens 10 væg 15, således at membranen 18 ved passende trykforhold . kan tætne mellem kanalen 10 og ringkammeret 11.Inside the sealing ring 21 is arranged a cylindrical 2Q pressure ring 27 which is pressed against the diaphragm 18 by a spring 28 supporting the sealing ring 21. Hereby the diaphragm 18 is pressed against the wall 15 of the channel 10, so that the diaphragm 18 at appropriate pressure conditions. can seal between channel 10 and ring chamber 11.

For at fjederen 28 kan støtte mod tætningsringen 21, har denne på den side, som vender modsat membranen 18, en anlægsflade 31, som via flige 29 er forbundet til tætningsringens 21 yderring 30.In order for the spring 28 to support the sealing ring 21, it has, on the side facing the diaphragm 18, a contact surface 31 which is connected via tab 29 to the outer ring 30 of the sealing ring 21.

Tætningsringen 21 udvider sig indvendigt fra den mod membranen 2g 18 vendende side, idet der dannes et ringformet trin i et større cylinderformet afsnit 32. Ligeledes udvider trykringén 27 sig på den side, der vender bort fra membranen 18, idet der dannes et ringformet trin på en rundtgående randdel 33, der befinder sig inden i tætningsringens 21 cylinderformede 25 afsnit 32. Trykringens 27 randdel 33 er gennembrudt af udskæ ringer 34, således at trykringen 27 kan føres ind i tætningsringen 21 og randdelen 33 herved blive placeret i afsnittet 32.The sealing ring 21 extends internally from the side facing the membrane 2g 18, forming an annular step in a larger cylindrical section 32. Likewise, the pressure ring 27 expands on the side facing away from the membrane 18, forming an annular step of a circumferential rim portion 33 located within the cylindrical portion 25 of the seal ring 21, the rim portion 33 of the pressure ring 27 is pierced by cut-outs 34 so that the pressure ring 27 can be inserted into the seal ring 21 and the rim portion 33 thereby being placed in the portion 32.
