Abstract

A loading bucket (1) designed to be an accessory to a vehicle such as a loading machine. The loading bucket (1) includes a rotating drum (2), which has opening (12) pointing towards the bucket's (1) mouth (23). The drum (2) is positioned against the bucket's (1) bottom (3) or sidewalls (4, 5) by rollers (13, 14), and the drum's (2) rear bracket (10) is connected via a shaft (15) with a rear bracket (6) on the bucket (1). Inside the bucket (1), there is a ramp (22), which is situated close to the drum's (2) opening (12). Furthermore a hydraulic motor (16) is attached to the bucket (1), which via a driving belt (20) etc. is arranged to rotate the drum (2) in a chosen direction. The drum (2) has in turned shovels (not shown). When the bucket (1) is mounted on a loading machine and the hydraulic motor (16) gets its pressure fluid supply from the loading machine, the bucket (1) is operated as follows. The loading bucket (1) is pushed into a heap of sand so that sand pours into the bucket's (1) outer part (23) cement is added to the sand and then the bucket (1) is tilted diagonally upwards so that the sand and cement run into the drum (2). Then water is added to the drum (2), which during the period that the vehicle is moving to the setting place is allowed to rotate so as to retain a good concrete mix. For the actual setting, the bucket is tipped diagonally downwards so that the ready mixed concrete runs out of it.<IMAGE>

Description

15 20 25 .tï Ü 35 40 8400559-4 2 och fig. 4 schematiskt visar lastskopan i vy iv-iv enrigt rig. f. Fig. 4 and Fig. 4 schematically show the loading bucket in views iv-iv in one row. f.

Lastskopan l enligt uppfinningen är avsedd för en lastmaskin och skopan l innefattar en roterbart anordnad trumma 2. Last- skopan l uppvisar vidare en botten 3, två sidoväggar 4,5, en bakre gavel 6 och två fästen 7,8 för skopans anbringning vid fordonet. Trumman 2 innefattar en mantel 9, en bakre gavel 10 och en främre gavel i form av en kona 11 som uppvisar en central öpp- ning 12. Inuti trumman 2 är på konventionellt sätt anordnat ett lämpligt antal skovlar (ej visade), vilka har till uppgift att åstadkomma en effektiv sammanblandning av den betong som skall blandas i trumman 2.The load bucket 1 according to the invention is intended for a loading machine and the bucket 1 comprises a rotatably arranged drum 2. The load bucket 1 further has a bottom 3, two side walls 4,5, a rear end wall 6 and two brackets 7,8 for mounting the bucket to the vehicle. . The drum 2 comprises a jacket 9, a rear end 10 and a front end in the form of a cone 11 which has a central opening 12. Inside the drum 2 a suitable number of vanes (not shown) are arranged in a conventional manner, which have to task of achieving an effective mixing of the concrete to be mixed in the drum 2.

Trumman 2 är roterbart anordnad genom att mantelns 9 ytter- yta anligger mot med skopans l botten 3 eller sidoväggar 4,5 roterbart förbundna hjul eller rullar 13,14 och genom att det mellan trummans 2 bakre gavel 10 och skopans l bakre gavel 6 är anordnat en axel 15, vilken är fast förbunden med skopgaveln 6 och via en lagring (ej visad) roterbart förbunden med trumgaveln 10 eller vice versa. Denna lagring är vidare så utformad att den axiellt fasthåller trumman 2 i skopans l längdriktning.The drum 2 is rotatably arranged by the outer surface of the jacket 9 abutting against wheels or rollers 13,14 rotatably connected to the bottom 3 or side walls 4,5 of the bucket 1 and by the arrangement between the rear end 10 of the drum 2 and the rear end 6 of the bucket 1 a shaft 15, which is fixedly connected to the bucket end 6 and via a bearing (not shown) rotatably connected to the drum end 10 or vice versa. This bearing is further designed so that it axially holds the drum 2 in the longitudinal direction of the bucket 1.

Lastskopan l uppbär vidare en hydraulmotor 16, vilken i det visade utföringsexemplet är förbunden med en uppåt utskjutande förlängning 17 hos skopans l bakre gavel 6. Hydraulmotorn 16 får sin tryckoljeförsörjning från lastmaskinen. Hydraulmotorns l6 drivaxel 18 uppbär en remskiva 19, vilken via en rem 20 driver en med trumgaveln 10 förbunden remskiva 21 varigenom rotation hos trumman 2 åstadkommes. Motorn 16 bör lämpligen medge rota- tion av trumman 2 i valfri riktning. I stället för remdrift kan man naturligtvis också använda sig av exempelvis kedjedrift el- ler kuggdrift. Om så är erforderligt kan motorns 16 varvtal ytterligare nedväxlas med hjälp av en mellanliggande reduktions- växel.The load bucket 1 further carries a hydraulic motor 16, which in the embodiment shown is connected to an upwardly projecting extension 17 of the rear end 6 of the bucket 1. The hydraulic motor 16 receives its pressure oil supply from the loader. The drive shaft 18 of the hydraulic motor 16 carries a pulley 19, which via a belt 20 drives a pulley 21 connected to the drum end 10, whereby rotation of the drum 2 is effected. The motor 16 should suitably allow rotation of the drum 2 in any direction. Instead of belt drive, you can of course also use, for example, chain drive or gear drive. If necessary, the engine 16 speeds can be further downshifted using an intermediate reduction gear.

I anslutning till trummans 2 öppning 12 är anordnat en med skopans l botten 3 och sidoväggar 4,5 förbunden inloppsramp 22, vilken bland annat har till uppgift att styra i skopans 1 ytter- del 23 beläget blandningsmaterial så att detta kan inrinna i trumman 2 när skopan 1 med hjälp av fordonet lutas snett uppåt.In connection with the opening 12 of the drum 2, an inlet ramp 22 connected to the bottom 3 and side walls 4,5 of the bucket 1 is arranged, which, among other things, has the task of guiding mixing material located in the outer part 23 of the bucket 1 so that it can enter the drum 2 when bucket 1 with the help of the vehicle is tilted obliquely upwards.

Det är vidare lämpligt att anordna en eller flera öppningar (ej visade) i den del av skopans 1 botten 3 som är belägen inunder trumman 2 för att därigenom undvika-att sand och dylikt samlas därstädes. ii! 10 20 25 30 8400559-4 Lastskopar enligt uppfinningen är såsom tidigare nämnts i första hand avsedd att användas tillsammans med fordon i form av lastmaskiner, t.ex. s.k. hjullastare/baklastare, varvid skopan l medelst fästena 7,8 monteras vid lastarens armar och hydraul- motorn 16 anslutes till lastarens hydrauloljeuttag.It is furthermore suitable to arrange one or more openings (not shown) in the part of the bottom 3 of the bucket 1 which is located below the drum 2 in order thereby to avoid sand and the like collecting there. ii! As previously mentioned, loading buckets according to the invention are primarily intended to be used together with vehicles in the form of loaders, e.g. s.k. wheel loader / rear loader, whereby the bucket 1 is mounted by means of the brackets 7,8 at the loader's arms and the hydraulic motor 16 is connected to the loader's hydraulic oil outlet.

Användning av det nyssnämnda ekipaget tillgár enligt följan- de. Skopans l ytterdel 23 fylles med exempelvis sand genom att den införes en viss längd i en sandhög. Lastskopans 1 ytterdel 23 kan lämpligen vara så dimensionerad att den sandmängd som därvid normalt kvarstannar däri motsvarar den sandmängd som be- hövs till en säck cement av viss storlek för att ett normalt blandningsförhållande skall erhållas. Därefter appliceras cement i skopans 1 ytterdel 23 varefter skopan l lutas snett uppåt så att sanden och cementen inrinner i trumman 2. Därefter tillsättes en lämplig mängd vatten i trumman 2, vilken hela tiden under for- donets förflyttning fram till gjutstället får rotera i den för erhållande av god sammanblandning avsedda rotationsriktningen.Use of the aforementioned crew is as follows. The outer part 23 of the bucket is filled with, for example, sand by inserting it a certain length into a pile of sand. The outer part 23 of the load bucket 1 can suitably be dimensioned so that the amount of sand which normally remains therein corresponds to the amount of sand needed for a sack of cement of a certain size in order to obtain a normal mixing ratio. Then cement is applied in the outer part 23 of the bucket 1, after which the bucket 1 is inclined obliquely upwards so that the sand and cement enter the drum 2. Then a suitable amount of water is added to the drum 2, which is constantly rotated in the vehicle. obtaining good mixing for the direction of rotation.

Vid själva gjutningen lutas skopan l snett nedåt så att den färdigblandade betongen utrinner ur densamma. Härvid är det lämpligen anordnat så att fordonets förare med fjärrmanövrering kan ändra trummans 2 rotationsriktning så att de i trumman 2 belägna skovlarna hjälper till att trycka ut betongen ur trum- man 2. Eftersom lastskopan enligt uppfinningen uppbäres av en lastare kan man oftast utportionera betongen direkt på använd- ningsstället, vilket är synnerligen tidsbesparande.During the actual casting, the bucket 1 is tilted obliquely downwards so that the ready-mixed concrete flows out of it. In this case, it is suitably arranged so that the driver of the vehicle with remote control can change the direction of rotation of the drum 2 so that the vanes located in the drum 2 help to push the concrete out of the drum 2. Since the loading bucket according to the invention is supported by a loader, the concrete can usually be dispensed directly at the place of use, which is extremely time-saving.

Vidare är det ur arbetsskyddssynpunkt lämpligt att anordna en överbyggnad (ej visad) över trumman och remtransmissionen. En sådan överbyggnad kan naturligtvis utformas på en mängd olika sätt.Furthermore, from the point of view of occupational safety, it is appropriate to arrange a superstructure (not shown) over the drum and the belt transmission. Such a superstructure can of course be designed in a variety of ways.

Uppfinningen är inte begränsad till det visade och beskriv- na, utan ändringar och modifikationer därav är tänkbara inom ramen för efterföljande patentkrav.The invention is not limited to what is shown and described, but changes and modifications thereof are conceivable within the scope of the appended claims.
