Definitions

• the present invention relates to a bulk store for storing bulk material in at least one pile and comprising a bulk storing area being laterally delimited by a longitudinally extending delimiting wall and a reclaiming device of the side scraper type movable on a pair of tracks arranged alongside the wall and having a pivotal scraper jib with a scraper chain extending into and over the bulk storing area for reclaiming material from the pile and a counterweight for counterbalancingthe scraper jib scraping material over the wall and into a belt conveyer arranged laterally outside the wall.
• the belt conveyer is arranged between the wall and the track closest to the wall.
• the pivot axis of the pivotal scraper jib is arranged close to the wall and thereby laterally between the wall and the track closest to the wall.
• the pivot axis of the scraper jip is arranged outside the tracks supporting the wheels of the side scraper why a large counterweight is needed to counter balance the jib.
• the need of a large counterweight means that the width of the side scraper must be increased and the belt conveyer arranged between the wall and the track closest to the wall requires space laterally outside the wall. As in known bulk stores of the above type, the side scraper and the belt conveyer require relatively much space laterally outside the delimiting wall.
• the object of the present invention is to provide a bulk store requiring less counterweight for counterbalancing the scraper jib and less space laterally outside the delimiting wall and thereby a bulk store requiring a smaller ground area than known bulk stores of the above type, which is particularly advantageous in bulk stores additionally comprising a building structure enclosing the bulk storing area, the rails and the side scraper.
• the present invention relates to a bulk store for storing bulk material in at least one pile and reclaiming bulk material from the pile, and comprising a bulk storing area being laterally delimited by a longitudinally extending delimiting wall, the delimiting wall having a lower upwardly extending preferably upright wall portion having an inner and an outer surface and an upper wall portion extending outwardly away from the bulk storing area at an upper end of the lower wall portion and having an upper and a lower surface, preferably an outwardly and slightly upwardly inclining upper surface, a bulk material reclaiming device of the side scraper type comprising a main frame with a pivotally mounted scraping jib being vertically pivotal about an essentially horizontal pivot axis and extending over the delimiting wall and into and over said bulk storing area for reclaiming material from the at least one pile in the bulk storing area and a counterweight for balancing the scraper jib, the main frame of the reclaiming device being configured to be movable along means for guiding and supporting the
• wheel means is to be understood one or more wheels, rollers and the like, both of the motor driven type and of the non-driven type, said term also covering bogies.
• the belt conveyer is arranged between the first and second track and thereby also between the wheel means, the first track, i.e. the track closest to the delimiting wall, can be arranged close to the delimiting wall and the required space laterally outside the wall decreased.
• the pivot point of the scraper jib can, as seen in a cross sectional view, be arranged between the tracks and thereby between the wheel means of the side scraper, thereby reducing the required counterweight for counterbalancing the scraper jib.
• the required space outside the wall is reduced further.
• the reduced counterweight required also reduces the costs of the side scraber.
• the first and second track can be arranged at a level lower than the upper wall portion of the delimiting wall.

• the required counterweight for counterbalancing the scraper jib is reduced by arranging the pivot axis between the tracks and thereby the wheel means as seen in a cross sectional view.
• the pivot axis of the scraper jip can be arranged in such a level above the upper portion of the delimiting wall that the scraper jib does not interfere with the upper wall portion when the scraper jib is pivoted downwardly to an essentially horizontal position and preferably also when the scraper jib is pivoted downwardly to a downwardly pivoted position in which an outer end of the scraper jib is below horizontal and slightly above the floor of the bulk storing area.
• the inclination of the upper surface of the upper wall portion of the delimiting wall is between 0° and 20°, alternatively between 5° and 15°, such as between 7° and 1 1°.

• the bulk store comprises a building structure with lateral walls and a roof enclosing the bulk-store area, the reclaiming device, the tracks along which the reclaiming device is movable and the belt conveyer.
• the bulk store comprises a building structure
• the above mentioned reduced lateral space required is especially advantageous as the width of the building structure and thereby the roof are reduced correspondingly and the cost for the building structure.

• the first track 12 is arranged closer to the delimiting wall 3 than the second track 13.
• the tracks extend over the entire length of the delimiting wall 3.
• the first track 12 is arranged below the upper wall portion 5 of the delimiting wall 3, the upper wall portion extending over and beyond the first track 12.
• the delimiting wall 3 has a height h corresponding to that of an upright grownup person when measured between the floor 10 and the lower surface 7 of the upper wall portion 5 of the delimiting wall 3.

• the second wheel means 16 comprises a wheel arrangement 16a comprising at least one wheel and being, as seen in a plan view, arranged at the corner 18 opposite the mentioned side 17 facing the wall 3.
• a scraper jib 19 is mounted pivotally about a horizontal pivot axis 20 on the main frame 14 of the reclaiming device 8 and extends over the delimiting wall 3 and into and over the bulk storing area 1 for reclaiming material from the pile.
