DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for loading manageable material into containers or moulds with the aid of a mechanical shovel or scoop, and particularly, although not exclusively, into so-called large sacks intended for the transportation or storage of the material, the arrangement comprising a mechanical shovel which can be attached to a shovel loader in a conventional manner and which has one open side through which the shovel can be filled.
The use of so-called large sacks for transporting and storing various kinds of granular and lump materials, such as agricultural produce, coal and the like, is becoming more and more general. It is also conceivable to use so-called large sacks to transport and to store, e.g., gravel-like materials, potting composts, topsoil, etc. The filling of such sacks, however, is relatively trouble-some and time-consuming when applying present day techniques. For example, when large sacks are used to distribute coal to the consumer, the coal, which is normally stacked in high mounds, must first be packed into the sacks by the supplier. This may involve the use of a conveyor belt onto which the coal can be shovelled and carried to a conical-bottom loading hopper for filling the sacks. Subsequent to being filled, it is necessary to transport the sacks, e.g. by truck, to a storage site. The aforedescribed procedure thus comprises a number of separate working stages and requires the mutual cooperation of several people, i.e. to load the coal onto the conveyor belt, to monitor the function of the belt, to attach the sacks to the bottom of the hopper, super-intended filling of the sacks, and to transport the filled sacks to their destination.
The dust generated when filling the sacks is also liable to create a harmful environment in the near vicinity of the sacks. Furthermore, if the sacks are not filled satisfactorily or to capacity, the at least partially filled sacks are normally too heavy to be lifted manually to the ground and the contents thereof shaken-up so as to compact in the sack.
The main object of the present invention is to provide an arrangement which, among other things, eliminates the aforesaid drawbacks and which, inter alia, enables large sacks to be filled in a highly rational and efficient fashion by means of a single workman, without requiring risky or harmful procedures to be carried out.
The invention is thus based on a desire to eliminate the loading procedure which entails first transferring coal onto a conveyor belt with the aid of a mechanical shovel or like device, and transporting the coal to a feed hopper or corresponding apparatus, from which the sacks are then filled. This stage in conventional filling procedures has been eliminated in accordance with the present invention, by transferring the coal, or corresponding material from the mechanical shovel directly into the sack.
In addition to being employed to fill large sacks and like containers, the invention may also be applied in other contexts when dealing with loose or pourable materials, e.g. when filling containers or moulds, such as concrete forms and, for instance, when casting concrete footings and concrete plinths, grouting in fence posts, and like work in which it is necessary to transport material between different locations and sites but where only a relatively small amount of material is utilized at each such location. The inventive arrangement may, of course, also be used to portion out material in circumstances other than those mentioned.
In accordance with the invention, an arrangement of the kind defined in the introduction is mainly characterized in that the shovel-defining wall which is located opposite the open side of the shovel and which when this open side faces upwards forms the bottom of the shovel is at least partially funnel-shaped; in that the passageway through this funnel-shaped part is provided with closure means; and in that said funnel-shaped part is configured to co-act with the filling opening of the container to be filled such as to enable a desired q
