Den foreliggende opfindelse angår en tvangsblander for beton, mørtel eller et lignende støbeligt materiale og af den i..indledningen til krav 1 angivne art.The present invention relates to a composite mixer for concrete, mortar or similar moldable material and of the kind set forth in the preamble of claim 1.

Det er almindeligt at anvende tvangsblandere til blan-5 ding af beton, idet disse blandere er kendt for at have en god blandeeffekt, hvorved man på kort tid kan opnå en fuldstændig ensartet charge af betonen. I stationære installationer er rengøring efter brug ikke noget større problem, idet man dér normalt har rigeligt vand til rådighed og i 10 reglen også gode muligheder for at skille sig af med skyllevandet.It is common to use coercive mixers for mixing concrete, these mixers being known to have a good mixing effect, whereby a completely uniform charge of the concrete can be achieved in a short time. In stationary installations, cleaning after use is not a major problem, since there is usually plenty of water available and, in principle, good opportunities to get rid of the rinsing water.

Fra beskrivelsen til svensk patent nr. 121.881 kendes en sådan betonblander, hvor rotoren har svingbart lejrede og med en fjederkraft påvirkede arme. Fjederkraf-15 ten bevirker en opadrettet kraft på rotorens nav, der følgelig må være effektivt fastgjort til udgangsakslen og derfor er vanskeligt at aftage ved rengøring.From the specification of Swedish Patent No. 121,881, such a concrete mixer is known in which the rotor has pivotally mounted and spring-loaded arms. The spring force exerts an upward force on the hub of the rotor, which must consequently be effectively attached to the output shaft and is therefore difficult to remove by cleaning.

Ved transportable installationer er der ikke under alle forhold tilsvarende gunstige muligheder for rengøringen 20 efter brugen eller ved overgang til andre mørteltyper, af hvilken grund det ved sådanne installationer er ønskeligt, at blanderen er særlig simpel at rengøre.In transportable installations, under all conditions there are not equally favorable possibilities for cleaning 20 after use or when switching to other types of mortar, for which reason it is desirable in such installations that the mixer is particularly simple to clean.

Formålet med den foreliggende opfindelse er at tilvejebringe en tvangsblander, der er særlig enkel at rengøre, 25 således at den bekvemt kan anvendes også under forhold, hvor vand til skylning ikke umiddelbart er til rådighed i rigelige mængder.The object of the present invention is to provide a compulsive mixer which is particularly simple to clean, so that it can be conveniently used even in conditions where water for rinsing is not readily available in copious amounts.

Tvangsblanderen ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 angivne. På 30 grund af rotorens aftagelighed vil kar og rotor kunne rengøres hver for sig. Rotoren behøver ikke fastgørelse på motorens udgangsaksel, fordi der ved rotationen opstår en ned-adrettet kraft fra mørtelen, hvilken kraft holder de to koblingsdele sammen.The forced mixer according to the invention is characterized by the characterizing part of claim 1. Due to the removability of the rotor, vessels and rotor can be cleaned separately. The rotor does not need attachment to the output shaft of the motor because during rotation, a downward force is generated from the mortar, which holds the two coupling parts together.

35 Den lette adskillelse er en yderligere fordel ved transportable installationer, fordi rotoren umiddelbart kan udtages, hvorved man ved flytning, fx op eller ned ad trapper, kan gøre blandekarret, der skal bæres som en enhed, 235 The easy separation is a further advantage of transportable installations because the rotor can be removed immediately, whereby when moving, for example up or down stairs, the mixing vessel to be carried as a unit can be made 2

lettere at bære.easier to carry.

Fortrinsvis er forbindelsen mellem udgangsakslen og rotornavet udformet som angivet i krav 2.Preferably, the connection between the output shaft and the rotor hub is formed as set forth in claim 2.

Opfindelsen skal i defcfølgende beskrives nærmere 5 under henvisning til tegningen, på hvilken:The invention will be described in more detail below with reference to the drawing, in which:

Fig. 1 viser tvangsblanderen set fra siden delvis gennemskåret, fig. ^2 viser tvangsblanderen set bagfra, fig. 3 viser blanderotoren set ovenfra, 10 fig. 4 viser motorens udgangsaksel set fra siden.FIG. 1 is a side sectional view of the forced mixer; FIG. ^ 2 is a rear view of the forced mixer; 3 is a top plan view of the mixer; FIG. 4 is a side view of the engine output shaft.

På tegningens fig. 1 er tvangsblanderen ifølge opfindelsen vist set fra siden delvis gennemskåret. Tvangsblanderen omfatter et cylindrisk blandekar 1, der er åbent opefter. For neden er blandekarret 1 lukket med en bund 2, i hvilken 15 der er placeret en udløbsåbning, der er forsynet med en udløbsslidsk 3. Blandekarret 1 er forsynet med ben 4, hvoraf to er forsynet med hjul 5. Endvidere er der til blandekarrets bund 2 fastgjort en trækstang 6, hvormed tvangsblanderen kan løftes op og køres på hjulene 5. Benene 4 består af to rør 20 4a,4b, hvoraf det ene er skudt teleskopisk ind i det andet og i det udvendige rør er der to overfor hinanden placerede huller, medens der i det inderste rør er flere hulpar. Gennem hullerne i de udvendige og indvendige rør er anbragt en låse-clips 7. Der er derved opnået mulighed for at ændre længden 25 på benene og dermed højden på blanderen. løvrigt er benene udløseligt fastgjort til blanderen og fastlåst på tilsvarende måde ved hjælp af en låseclips 8, der er indsat gennem huller i benet 4 og i en på blandekarret 1 anbragt fastgørelsesbøsning 9. Trækstangen er ligeledes udløseligt fastgjort til 30 blandekarret og fastholdt ved hjælp af en låseclips 10. Aftageligheden af benene 4 og trækstangen 6 reducerer dimensionerne af blanderen under transport. Reduktionen af dimensionerne er så betydelig, at en tvangsblander med 30 1 blande-kapacitet kan finde plads i bagagerummet på en almindelig per-35 sonbil af mellemstørrelse.In the drawing FIG. 1, the forcible mixer according to the invention is partially cut away from the side. The forced mixer comprises a cylindrical mixing vessel 1 which is open upwards. Below, the mixing vessel 1 is closed with a bottom 2, in which is located an outlet opening, which is provided with an outlet slide 3. The mixing vessel 1 is provided with legs 4, two of which are provided with wheels 5. Furthermore, the bottom of the mixing vessel is provided. 2, a drawbar 6 is fastened, by means of which the forced mixer can be lifted up and driven on the wheels 5. The legs 4 consist of two tubes 20 4a, 4b, one of which is telescopically shot into the other and in the outer tube there are two holes positioned opposite each other , while in the inner tube there are several hollow pairs. A locking clip 7. is provided through the holes in the outer and inner tubes, thereby allowing the length of the legs 25 to be changed and thus the height of the mixer. The legs are releasably attached to the mixer and are similarly secured by means of a locking clip 8 inserted through holes in the leg 4 and in a mounting sleeve 9 mounted on the mixing vessel 1. a locking clip 10. The removability of the legs 4 and the drawbar 6 reduces the dimensions of the mixer during transport. The reduction of dimensions is so significant that a 30 liter mixer compulsory mixer can find space in the trunk of a regular mid-size passenger car.

Bunden 2 har et centralt hul, gennem hvilket et lejetårn 11 er ført. Lejetårnet har en flange, der er fastspændt til bunden ved hjælp af bolte 12. Boltene 12 tjener tilligeThe bottom 2 has a central hole through which a bearing tower 11 is passed. The bearing tower has a flange which is clamped to the bottom by means of bolts 12. The bolts 12 also serve

3 til fastspænding af en flangemonteret gearmotor 13. I det viste udførelseseksempel er gearmotoren udstyret med et snekkegear/ men et tandhjulsgear med cylindriske tandhjul og en passende stor udveksling er også anvendelig, idet motoren i 5 så fald vil hænge lodret nedefter. Udvekslingen i gearet skal vælges således, at gearmotorens 13 udgangsaksel 14 får et omdrejningstal i området fra 10 - 40 omdr./min. Tårnet 11 bærer øverst et léje for udgangsakslen 14. Udgangsakslen, der rager op over tårnet, er øverst forsynet med en flange 15.3 for clamping a flange mounted gear motor 13. In the illustrated embodiment, the gear motor is equipped with a worm gear / but a gear gear with cylindrical gears and a suitably large exchange is also applicable, in which case the motor will then hang vertically downwards. The gear ratio must be selected such that the output shaft 14 of the gear motor 13 receives a speed in the range of 10 - 40 rpm. The tower 11 carries a bearing at the top of the output shaft 14. The output shaft protruding above the tower is provided with a flange 15 at the top.

20 Udgangsakslen 14 er vist på fig. 4. Flangen 15 har to medbrin-gere 16, der tjener til at drive tvangsblanderens blande-rotor 17. Til centrering af blanderotoren rager akslen 14 op gennem flangen 15. På undersiden af flangen 15 er fastgjort et skørt 18, der tjener til at holde blandegodset borte fra 25 lejet i tårnet 11.20 The output shaft 14 is shown in FIG. 4. The flange 15 has two brackets 16 which serve to drive the mixer mixer rotor 17. For centering of the mixer rotor shaft 14 protrudes through the flange 15. On the underside of the flange 15 is secured a skirt 18 which serves to hold the mixed goods away from the 25 bed in the tower 11.

Blanderotoren 17 er vist på fig. 3 og omfatter et nav 19 med et centreringshul 20. Blanderotoren har fire blande-arme 21, der er forsynet med blandeskovle. Blandeskovlene er skrå, dels i forhold til blanderotorens akse på en sådan 20 måde, at blandegodset ved rotorens rotation påvirker rotoren med en nedadgående kraft, dels skrå i forhold til den gennem skovlen gående radius. De skrå vinkler har til formål først og fremmest at sikre en effektiv omrøring og sammenblanding af det gods, der anbringes i blandekarret. Den skrå vinkel i 25 forhold til rotoraksen sikrer desuden, at navet 19 under rotationen presses mod flangen 15, hvorved en egentlig fastspænding af rotoren ud over centreringen og den drejefaste forbindelse ved hjælp af medbringerne, der griber ind i huller på navets underside, overflødiggøres. Det er en væsent-30 lig lettelse ved rengøring af blanderen efter brugen, at rotoren umiddelbart kan tages af blot ved at blive løftet op. De skrå vinkler i forhold til radius kan afpasses således, at de radiale kræfter i det mindste til en vis grad udbalancerer hinanden.Mixer rotor 17 is shown in FIG. 3 and comprises a hub 19 with a centering hole 20. The mixing rotor has four mixing arms 21 provided with mixing vanes. The mixing vanes are inclined, partly in relation to the axis of the mixing rotor, in such a way that the mixing goods, upon rotation of the rotor, affect the rotor with a downward force and partly inclined in relation to the radius passing through the vane. The oblique angles are primarily intended to ensure effective agitation and mixing of the goods placed in the mixing vessel. The oblique angle relative to the rotor axis also ensures that the hub 19 is pressed against the flange 15 during rotation, thereby eliminating an actual clamping of the rotor beyond the centering and the pivotal connection by means of the drivers engaging in holes on the underside of the hub. It is a significant relief when cleaning the mixer after use that the rotor can be immediately removed simply by being lifted. The oblique angles to the radius can be adjusted so that the radial forces at least to some extent balance each other.

35 Som vist på fig. 2 er tvangsblanderen forsynet med en bakke 22, der er indrettet til at anbringe en sæk af det eller de materialer, der skal blandes eller oprøres med 435 As shown in FIG. 2, the forced mixer is provided with a tray 22 arranged to place a sack of the material or materials to be mixed or stirred with 4

DK 154965 BDK 154965 B

vand eller en anden væske. Blanderen er især egnet til op-røring af en forudfremstillet blanding af grus og cement eller kalk med vand. I så fald anbringes en pose eller sæk med den forudfremstillede blanding på bakken, hvorefter sækken 5 åbnes og indholdet tømmes ud i blandekarret. Ved hjælp af·en støttestang 23, der kan fastgøres i flere stilling, kan hældningen af bakken 22 ændres. Bakken 22 er iøvrigt aftagelig under transport eller når blanderen skal køres på sine hjul gennem smalle åbninger, såsom døre i almindelige boliger.=1 10 Udtømning af blanderens indhold sker ved hjælp af et spjæld i karrets bund. Spjældet betjenes ved hjælp af et håndtag 24.water or some other liquid. The mixer is particularly suitable for stirring a pre-made mixture of gravel and cement or lime with water. In this case, place a bag or bag of the pre-made mixture on the tray, after which the bag 5 is opened and the contents emptied into the mixing vessel. By means of a support bar 23, which can be fixed in several positions, the slope of the tray 22 can be changed. The tray 22 is also removable during transport or when the mixer is to be driven on its wheels through narrow openings, such as doors in ordinary dwellings. = 1 10 The contents of the mixer are emptied by means of a damper in the bottom of the tub. The damper is operated by means of a handle 24.

For at undgå overbelastning af motoren 13 er det hensigtsmæssigt, at der mellem motorens tilslutningsledning 25 15 og motoren er indkoblet en overbelastningssikring i form af et såkaldt motorværn 26. Motoren kan være forsynet med et beskyttelsesskjold 27, der er fastgjort til en konsol 28 på motoren ved hjælp af en skrue 29.In order to avoid overloading the motor 13, it is desirable that between the motor connection line 25 15 and the motor an overload protection in the form of a so-called motor protection 26 is connected. using a screw 29.
