The feeding system comprises one or more material storage devices and a discharge device associated with each storage device. Each discharge device comprises a conveyor channel tilted upwardly and away from its inlet arranged to be connected with the outlet of the storage device. A chute is adapted to be loosenably suspended, rapidly and simply, on the lower longitudinal side of the conveyor channel in a working position, a sampling position or in an emptying position, as required. In its working position the chute is positioned parallel to the conveyor channel, while the upper outlet of the conveyor channel opens into the chute at the upper end of the latter. In its sampling position the chute is tilted downward and away from the upper end of the conveyor channel at a right angle to the latter. In its emptying position the chute is tilted downward and away from the lower end, i.e. from the start of the conveyor channel and at a right angle to the latter. At this lower end the conveyor channel comprises a lower exit adapted to be closed off.
System for feeding at least one bulk material, the system comprising at least one storage device for storing bulk material, wherein a conveyor channel, a conveyor member and a chute each are provided for and associated with each said storage device, said conveyor channel is disposed below and is connected with an associated storage device and is provided with an entrance communicating with the inner space of said associated storage device and an exit, said conveyor channel is disposed sloping upward from said entrance to said exit, said conveyor member is mounted in said conveyor channel and adapted to convey along said conveyor channel bulk material entering said conveyor channel from said associated storage device, each said chute is adapted to be removably connected in at least two distinct positions with an associated said conveyor channel to carry bulk material coming therefrom in a downward direction, each chute extending, in a first of said distinct positions along a bottom boundary of said associated conveyor channel and having said exit open into the respective chute, so that any bulk material arriving from said exit into said chute slides through said chute downward in a direction parallel but opposite to the direction along which the bulk material is conveyed inside said associated conveyor channel from the entrance thereof to said exit, said chute being arranged to form an angle with said associated conveyor channel in at least one further of said at least two distinct positions.
System for feeding at least one bulk material, the system comprising storage devices for storing bulk material, wherein a conveyor channel, a conveyor member and a chute each are provided for and associated with each said storage device, wherein each conveyor channel is disposed below and is connected with said associated storage device and is provided with an entrance communicating with the inner space of said associated storage device and an exit, said conveyor channel is disposed sloping upward from said entrance to said exit, wherein, furthermore, a said conveyor member is mounted in each said conveyor member channel and is adapted to convey along said conveyor channel bulk material entering said conveyor channel from said associated storage device, each said chute is adapted to be removably connected in at least two distinct positions with an associated said conveyor channel and to carry bulk material coming therefrom in a downward direction, each chute extending in a first of at least two distinct positions along a bottom boundary of said associated conveyor channel, said exit opening from said conveyor channel into the associated said chute so that any bulk material arriving from said exit into said chute is enabled to slide through said chute downward in a direction parallel but opposite to the direction along which the bulk material is conveyed inside said conveyor channel from the entrance thereof to its exit and wherein each said conveyor channel is arranged to diverge in upward direction and said chutes are arranged to converge in their first position in a downward direction, each said chute further being arranged to form an angle with said associated conveyor channel in at least one further of said at least two distinct positions.
System for feeding at least one bulk material, the system comprising at least one storage device for storing bulk material, wherein a conveyor channel, a conveyor member and a chute each are provided for and associated with each said storage device, wherein said conveyor channel operatively connected with said associated storage device is arranged to slope upwardly, a lower end section of said conveyor channel having an entrance communicating with an inner space of said associated storage device, a first exit at an upper end section of said conveyor channel and a second exit at a lower end section below said entrance, said second exit being adapted to be closed off by means of a displaceable locking member, a said conveyor member mounted in each said conveyor channel is adapted to convey bulk material from said entrance to said first exit and to enable, in all of its possible positions, bulk material to move under the action of the force of gravity, from the said entrance to and through said second exit when said second entrance is open, each said chute is adapted to be removably connected to an associated said conveyor channel in one of at least two distinct positions, in a first position said chute extends along a bottom boundary of said conveyor channel, in said first position of said chute said first exit open into said chute in a location disposed in cross-section on the upper side of said chute so that any bulk material arriving from said first exit into said chute is enabled to slide through said chute downwardly, in a direction parallel to but opposite from the conveying direction along which the bulk material is conveyable inside said conveyor channel from said entrance thereof to its first exit, and wherein in a further position of said at least two distinct positions in which each chute can be connected with said associated conveyor channel, said chute forms an angle with said conveyor channel and rests with an open end on said conveyor channel at said second exit of said channel in a way to have second exit open into said chute.
