Description

Uppfinnare: Hagstam och E Paulsen Prioritet begiird !ran den 29 mars 1961 (Danmark) Denna uppfinning avser en borrapparat for uttagning av inre organ frail slaktdjur, sr-skin for uttagning av hypofysen, vilken apparat har ett vid den roterande axeln hos en motor, foretradesvis en tryckluftmotor, fastgjort rorformigt borr. Inventors: Hagstam and E. Paulsen Priority application, March 29, 1961 (Denmark). This invention relates to a drilling apparatus for removing internal organs from slaughter animals, a sr-skin for removing the pituitary gland, which apparatus has one at the rotating shaft of a motor. preferably a compressed air motor, attached tubular drill.

Det är kant att anvanda sadana borrapparater for uttagning av hypofysen fran slaktdjur, men det har vid bruket av sadana apparater visat sig vara ratt besvarligt att fa den det rorformiga borret befintliga proppen avlagsnad, i det att detta avlagsnande mast goras med yttersta forsiktighet for att icke riskera, att vardefulla delar gá till spillo. Nar hypofysen uttages, befinner sig denna, som fir jamforelsevis liten, mitt inne i en propp, som bestar av benvavnad, hjarnmassa och andra delar av slaktdjurets huvud, och det är av vikt, att man far ut proppen som en samlad enhet, sâ att man darefter med omsorg kan sortera innehallet i proppen. Detta har joke varit mOjligt vid de hittills kanda borrapparaterna, dar man har mast skrapa tit proppen eller ocksa har varit n8dsakad att losgbira borret fran borrmaskinen, st att man blev i stand att trycka proppen direkt ut genom borret. Detta fir naturligtvis ett besvarligt tillvagagangssatt, och andamalet med fordiggande uppfinning är att angiva en borrapparat, med vilken man helt undgar dessa olagenheter. Detta uppnas enligt uppfinningen genom att den narmast motoraxeln belagna delen av det rorformiga borrets inre halrum genom en avstangningsventil or anslutet till en tryckluftlEfilla. It is possible to use such drilling devices for removing the pituitary gland from slaughter animals, but in the use of such devices it has been found to be quite responsible to have the plug present in the tubular drill removed, in that this removing mast is done with the utmost care not to risk that valuable parts were wasted. When the pituitary gland is removed, it is located, which is relatively small, in the middle of a clot, which consists of bone tissue, brain mass and other parts of the slaughter animal's head, and it is important that the clot is removed as a single unit, so that you can then carefully sort the contents of the stopper. This joke has been possible with the hitherto known drilling devices, where you have had to scrape the plug or also have had to loosen the drill from the drilling machine, so that you were able to push the plug directly out through the drill. This, of course, is a reasonable approach, and the object of the preceding invention is to provide a drilling rig with which these disadvantages are completely avoided. This is achieved according to the invention by the part of the inner cavity of the tubular drill covered by the nearest motor shaft through a shut-off valve or connected to a compressed air valve.

Genom att utforma horrapparaten pa detta satt uppnar man, att man genom betjaning av avstangningsventilen blir i stand att in-fora tryckluft bakom den propp, som har blivit sittande inne i borret efter utborrningen, och darigenom kan proppen tryckas ut son) en samlad enhet, utan att det i ovrigt skall ske nagon isartagning av apparaten eller foretagas andra manovrar. By designing the hearing aid in this way, it is achieved that by operating the shut-off valve it is possible to introduce compressed air behind the plug which has remained inside the drill after drilling, and thereby the plug can be pushed out as a single unit, without any other disassembly of the apparatus or other maneuvers.

For att kunna anpassa det tryck, med vilket man pressar ut proppen genom borret, ãr det -vidare enligt uppfinningen att det i serie med avstangningsventilen ax insatt en strypventil. In order to be able to adapt the pressure with which the plug is forced out through the drill, it is further according to the invention that a throttle valve is inserted in series with the shut-off valve.

Vid anslutningen av tryckluften till rorborrets halrum fordras det naturligtvis en lamp-hg tathet, men denna tathet behOver dock joke vara overdrivet god, emedan det blott ax fraga om att utfora en kortvarig mekanisk funktion, dar man har rikligt tryck till f orfogande och salunda mindre f5rlust lake spelar flagon roll. Borrapparaten kan darfor vara utformad utomordentligt enkel, och en sadan mycket enkel och effektiv •konstruktion kannetecknas enligt uppfinningen av att borrroret ãr fastgjort i en cylindrisk bussning, som är fastskruvad ph motoraxeln och som har en i borroret utmynnande, axiellt fOr16- pande kanal och en dammed forbunden tvarkanal, vilken utmynnar innanfor ett ringformigt spar i insidan av en vid motorn fastgjord ring, som tatt omsluter bussningens cylindriska del. When connecting the compressed air to the rudder of the rudder drill, a lamp-high tightness is of course required, but this tightness needs to be excessively good joke, since it is only a question of performing a short-term mechanical function, where you have plenty of pressure available and thus less f5rlust lake plays flagon role. The drilling apparatus can therefore be designed extremely simple, and such a very simple and efficient construction can be characterized according to the invention in that the drill pipe is fixed in a cylindrical bushing, which is screwed to the motor shaft and which has an axially extending channel opening in the drill pipe and a dammed connected duct, which opens inside an annular groove in the inside of a ring attached to the motor, which has enclosed the cylindrical part of the bushing.

Uppfinningen skall i det foljande beskrivas narmare i samband med bifogade ritning, som visar en borrapparat enligt uppfinningen, sedd Iran sidan, delvis i sektion. The invention will be described in more detail below in connection with the accompanying drawing, which shows a drilling rig according to the invention, seen from the Iran side, partly in section.

Pa ritningen ser man en borrapparat, som bestar av en tryckluftmotor 1 med en utskjutande drivaxel 2, pa vilken det med hjalp av en eylindrisk bussning 3 fir fastgjort ett rorformigt borr 4. Bussningen 3 är fastgjord vid borret med hjalp av en tvargaende tapp 5 och har en axiell harming 6, som utmynnar i borr8ret. Vinkelratt mot borrningen 6 och i forbindelse med denna finnes en tvargaende kanal 7, och utanfor bussningen 3 ar anbragt 21 7 1 en fastsittande ring 8, som overtacker mynningarna av tvarkanalen 7 och har ett invandigt runtgaende spar 9, vilket genom en rorledning 10, en strypventil 11 och en avstangningsventil 12 star i forbindelse med en tryckledning 13, som over ett T-stycke 14 är forbunden dels med avstangningsventilen 12, dels med motorn 1. Bingen 8 är med hjalp av en bygel 15 fastspand vid motor. 1, sa att den hindras fran att rotera tillsammans med bussningen 3. Sparet 9 i ringen 8 är bildat med hjalp av tva packningar 16 och 17, i det att ringen tillika har en inatgaende flans 18, som tjanar till anslag for ett brost 19 pa bussningen 3. The drawing shows a drilling apparatus, which consists of a compressed air motor 1 with a projecting drive shaft 2, on which a tubular drill 4 is attached by means of a cylindrical bushing 3. The bushing 3 is fixed to the drill by means of a transverse pin 5 and has an axial harming 6, which opens into the drill. Perpendicular to the bore 6 and in connection therewith there is a transverse channel 7, and outside the bushing 3 a fixed ring 8 is arranged 21, which covers the mouths of the transverse channel 7 and has an internal circumferential groove 9, which through a pipeline 10, a throttle valve 11 and a shut-off valve 12 are connected to a pressure line 13, which is connected via a T-piece 14 partly to the shut-off valve 12 and partly to the motor 1. The bin 8 is clamped to the motor by means of a jumper 15. 1, so that it is prevented from rotating together with the bushing 3. The recess 9 in the ring 8 is formed by means of two gaskets 16 and 17, in that the ring also has an inwardly extending flange 18, which serves as an abutment for a breast 19 on the bushing 3.

Vid den har visade utforingen är bussningen 3 fastskruvad pa axeln 2, men den kan naturligtvis aven vara fastgjord pa godtyckligt annat lampligt satt, liksom Sven forbindelsen mellan rorborret och bussningen 3 kan utforas pa flera satt. In the embodiment shown, the bushing 3 is screwed onto the shaft 2, but it can of course also be fastened in any other suitable way, just as the connection between the pipe drill and the bushing 3 can be made in several ways.
