Description
szozsis-o Anordningen enligt föreliggande uppfinning är uppbyggd av enkla och robusta kom- ponenter, vilket gör att mekanismen blir slitstark och oöm. Detta uppnås enligt uppfinning- en såsom den definieras i efterföljande patentkrav. szozsis-o The device according to the present invention is built up of simple and robust components, which makes the mechanism durable and insensitive. This is achieved according to the invention as defined in the appended claims.
En utföringsform av uppfinningen kommer nu att beskrivas i anslutning till bifogade ritningar, på vilka fig. l i en sidovy visar en växelplog enligt uppfinningen med plogramen i transportläge och fig. 2a - Ze visar vridningsmekanismen vid olika tillstånd under vridnings- rörelsen.An embodiment of the invention will now be described in connection with the accompanying drawings, in which Fig. 1 shows in a side view a reversible plow according to the invention with the plograms in transport position and Figs. 2a - Ze show the turning mechanism at different conditions during the turning movement.
~ Som framgår av fig. 1 består växelplogen av ett vändhuvud ll] avsett att stumt infästas radiellt i dragfordonet. Vändhuvudet fortsätter bakåt såsom ett stabiliserings- rör ll, som övergår i ett fäste 12 för ett stöd- och transporthjul 13. Stabiliseringsröret uppbär en främre lagerhylsa 14 och en bakre lagerhylsa 15, som är lagrade för vridning pà röret. Den främre lagerhylsan 14 uppbär en glidskena 16, som är inställbar med hjälp av en cylinder 17, varvid glidskenan är fast förbunden med plogens ram 18. Detta arrangemang medger inställning av plogens arbetsbredd. Ramen är dessutom via en tapp 19 vridbart förbunden med den bakre lagerhylsan 15 och upptar ett antal T-formade plogåsar 20, som var och en på konventionellt sätt är försedd med en icke' visad höger- respektive vänster-läggande plogkropp.As can be seen from Fig. 1, the reversible plow consists of a turning head 11] intended to be mutually mounted radially in the towing vehicle. The turning head continues rearwardly as a stabilizing tube 11, which merges into a bracket 12 for a support and transport wheel 13. The stabilizing tube carries a front bearing sleeve 14 and a rear bearing sleeve 15, which are mounted for rotation on the tube. The front bearing sleeve 14 carries a slide rail 16, which is adjustable by means of a cylinder 17, the slide rail being fixedly connected to the plow frame 18. This arrangement allows adjustment of the working width of the plow. The frame is also rotatably connected to the rear bearing sleeve 15 via a pin 19 and receives a number of T-shaped plow geese 20, each of which is provided in a conventional manner with a right-hand and left-laying plow body, respectively, not shown.
Plogåsarna är lämpligen på känt sätt upphängda för att lösas ut vid påkörning av hinder i marken. Den främre lagerhylsan 14 är försedd med två par fästöron Zla, Zlb respektive 22a, 22b, vilka mellan sig vridbart upptar var sin länkarm 23 respektive 24.The plowshares are suitably suspended in a known manner to be released when obstacles are hit in the ground. The front bearing sleeve 14 is provided with two pairs of fastening ears Z1a, Z1b and 22a, 22b, respectively, which between them rotatably receive their respective link arms 23 and 24, respectively.
Vardera länkarmen 23, 24 är också vridbart förbunden med en kolvstång 25 respektive 26, vardera tillhörande en enkelverkande cylinder 27 respektive 28. Dessa cylindrar är vridbart infästa i den övre delen av en stabiliseringsröret ll tillhörande konsol 29. Den främre lagerhylsan 14 har två anslag 3D respektive 31 för de båda länkarmarna. Vardera cylindern är försedd med en ventil 32 som stryper tillförsel av olja vid cylinderns evakuering men släpper igenom fullt flöde vid dess fyllning. De båda cylindrarna 27 och 28 är anslutna till dragfordonets dubbelverkande hydrauluttag.Each link arm 23, 24 is also rotatably connected to a piston rod 25 and 26, respectively, each belonging to a single-acting cylinder 27 and 28, respectively. These cylinders are rotatably attached to the upper part of a stabilizing tube 11 associated bracket 29. The front bearing sleeve 14 has two stops 3D respectively 31 for the two link arms. Each cylinder is provided with a valve 32 which restricts the supply of oil during the evacuation of the cylinder but allows full flow through its filling. The two cylinders 27 and 28 are connected to the double-acting hydraulic outlet of the towing vehicle.
Anordningen fungerar på följande sätt, och härvid hänvisas huvudsakligen till fig. 2a - 2e.The device operates in the following manner, and reference is here mainly made to Figs. 2a - 2e.
I det i fig.2a visade läget intager plogen ett av sina arbetslägen, varvid de vänsterlàiggande plogkropparna är i ingrepp med marken. Begränsning av lagerhylsans rörelse i förhållande till stabiliseringsröret sker genom ett icke visat ställbart stopp.In the position shown in Fig. 2a, the plow assumes one of its working positions, the left-hand plow bodies engaging the ground. The movement of the bearing sleeve in relation to the stabilizing tube is limited by an adjustable stop (not shown).
Plogens ram ligger mot stoppet av sin egen tyngd. När vändningsrörelsen skall påbörjas, matas hydraulblja in i cylindern 28, varvid kolvstången 26 tryckas ut. Länkarmen 24 anligger mot anslaget 31 och pressar detta nedåt i fig. 2a, vilket får till följd att den främre lagerhylsan 14 vrides runt stabiliseringsröret 11 samtidigt som anslaget 30 närmar sig länkarmen 23. Under denna del av rörelsen påverkas ej kolvstången 25 i axialled och befinner sig hela tiden i sitt helt utskjutna läge. Cylindern 27 svänger därvid en mindre vinkel åt vänster i figuren. 82028215-0 När ramen har svängt till det i fig. 2b visade läget, gär anslaget 30 i ingrepp med länkarmen 23 och pressar kolvstàngen 25 inåt i cylindern 27, varvid strypningen i venti- len 32 tillser att vridningsrörelsen dämpas. För att säkerställa att vridningsrörelsen fullföljes över mittläget pressas länkarmen 24 av cylindern 28 :not anslaget 31 under ytterligare en mindre del av vridningsrörelsen tills kolvstàngen 26 nått sitt bottenläge i cylindern 28. Ramen har då kommit förbi nämnda mittläge enligt fig. 2c till den position som visas i fig. Zd.The plow's frame rests against the stop of its own weight. When the turning movement is to be started, hydraulic diaphragm is fed into the cylinder 28, whereby the piston rod 26 is pushed out. The link arm 24 abuts the stop 31 and presses it downwards in Fig. 2a, which has the consequence that the front bearing sleeve 14 is rotated around the stabilizing tube 11 at the same time as the stop 30 approaches the link arm 23. During this part of the movement the piston rod 25 is not actuated axially and is constantly in its fully extended position. The cylinder 27 then pivots a smaller angle to the left in the figure. 82028215-0 When the frame has pivoted to the position shown in Fig. 2b, the stop 30 engages the link arm 23 and presses the piston rod 25 inwards into the cylinder 27, the throttle in the valve 32 ensuring that the rotational movement is damped. To ensure that the rotational movement is completed over the center position, the link arm 24 is pressed by the cylinder 28: not stop 31 during a further small part of the rotational movement until the piston rod 26 reaches its bottom position in the cylinder 28. The frame has then passed said center position according to Fig. 2c to the position is shown in Fig. Zd.
I detta läge släpper anslaget 31 kontakten med länkarrnen 24 och tyngden av ramen med plogkropparna upptages genom samverkan av anslaget 30, länkarmen 23 och kolv- stången 25 av' 'cylindern 27, varvid vridningsrörelsen bromsas med hjälp av ventilen 32.In this position the stop 31 releases the contact with the link arms 24 and the weight of the frame with the plow bodies is absorbed by the interaction of the stop 30, the link arm 23 and the piston rod 25 of the cylinder 27, the rotational movement being braked by means of the valve 32.
När de högerläggande plogkropparna efter vridningsrörelsens fullbordan har gått i ingrepp med marken, befinner sig cylinderns 27 kolvstång 25 i sitt intryckta läge och vridningsrörelsen kan därefter upprepas åt motsatt häll.When the right-hand plow bodies, after the completion of the turning movement, have engaged the ground, the piston rod 25 of the cylinder 27 is in its depressed position and the turning movement can then be repeated in the opposite direction.
Det skall även observeras, att vridningsrörelsen kan avbrytas varsomhelst under rörelsen med dragfordonets hydraulventil i neutralläge. Vid det i fig.2c visade läget befinner sig plograrnen i transportläge, varvid de höger- och vänsterläggande plogkropparna är i jämvikt med varandra. Eventuella sidokrafter kan i detta läge ej paverka plogramen, da de båda cylindrarna 27, 28 låser ramen i transportläget.It should also be noted that the rotational movement can be interrupted anywhere during the movement with the towing vehicle's hydraulic valve in the neutral position. In the position shown in Fig. 2c, the plows are in transport position, the right and left plowing bodies being in equilibrium with each other. Any lateral forces can not affect the plogram in this position, as the two cylinders 27, 28 lock the frame in the transport position.
