Abstract

An arrangement for loading manageable material into containers or moulds with the aid of a mechanical shovel, and in particular to filling large sacks (10) intended for transporting or storing the matrial. The arrangement includes a mechanical shovel or scoop (5) which can be attached to a shovel loader in a conventional manner and which has an open side through which the shovel can be filled with material. The shovel defining wall located opposite the open side of the shovel when the open side thereof faces upwards is at least partially funnel-shaped (8). The passageway (9) through the funnel-shaped part is provided with a closure throttle (12) and the funnel-shaped part (8) is intended to co-act with the filling opening of the container (10) in a manner to enable a desired quantity of material to be transfered from the shovel to the container.

Claims

1. A method for filling 1 with the aid of a mechanical shovel 1 large sacks with manageable material for the purpose of transporting or storing said material, characterized by using a movable shovel loader equipped with a driving seat and a tiltable shovel which can be raised and lowered with the aid of lifting arms;

by filling the shovel with said material with the aid of the shovel loader, and tilting up the shovel;

by placing a sack around an openable and closeable opening in rear defining wall of the shovel, which wall forms the bottom of the shovel when the shovel is tilted upwards;

by opening said opening so as to transfer a desired quantity of said material from the shovel to the sack; and

by transporting the sack to a desired location with the aid of the loader and with the sack hanging from the shovel.

2. An arrangement for filling large sacks (10) with manageable material with the aid of a mechanical shovel, for the purpose of transporting or storing said material, comprising a movable shovel loader (1) equipped with driving seat a tiltable mechanical shovel (5) which can be raised and lowered with the aid of lifting arms and which has an open side through which the shovel can scoop up material, characterized in that a shovel defining wall which is located opposite said open side and which forms the bottom of the shovel when said open side faces upwards, is at least partially funnel-shaped (8);

the funnel-shaped part includes a passageway through which said material can flow from said shovel through said passageway (9) is provided with a closure means (12);

in that the arrangement further comprises means (11) for attaching a sack (10) to the shovel (5) so that said passageway (9) connected thereto projects into the mouth of the sack (10); and

in that said sack attachment means have the form of suspension means (11) which enable a filled sack (10) to be lifted and transported whilst hanging from the shovel.

3. An arrangement according to claim 2, characterized in that the closure means is a throttle (12) arranged in said passageway.

4. An arrangement according to claim 3, characterized in that said throttle has the form of an arcuately curved plate (12) which moves in an arcuate slot in said passageway (9).

5. An arrangement according to any one of claims 2, 3, or 4 characterized in that the closure means (12) is remotely controlled from the driving seat of the shovel loader (1), by means of a hydraulic device (13).
