Device for the distribution and burying of solid granular products, to be applied to a subsoiler or similar, comprising: - a frame, - a plurality of anchors (4,104) individually mounted on said frame and configured to create corresponding grooves in the ground intended to receive said solid granular products, - a plurality of substantially rigid ducts (38,56,56', 138) placed behind the respective anchors (4,104), - a plurality of supports, which are integral with said frame and to which said anchors (4,104) are articulated in order to be moved between an active condition, with their lower end introduced into the ground, and an inactive condition overturned backwards, following impact against an obstacle in the ground, - controlled yielding means, which keep each anchor (4,104) in an active condition in the absence of stresses exceeding a predetermined value, which should arise when said anchor (4,104) impacts against said obstacle, - at least one tank containing said granular product to be distributed and buried, - at least one supply duct connecting said tank with each of said substantially rigid ducts (38,56,56', 138) when the corresponding anchor (4,104) is in an active condition, wherein each of said substantially rigid duct (38,56,56', 138) is articulated to said anchor (4, 104), characterized in that each of said substantially rigid duct (38, 56, 56', 138) is associated with guide means, which following said controlled yielding make it pass from an active position, in which the upper end of said substantially rigid conduit (38,56,56', 138) communicates with said supply conduit, to an inactive position, in which the upper end of said substantially rigid duct (38,56,56', 138) is decoupled from said supply duct. - a frame, - a plurality of anchors (4,104) individually mounted on said frame and configured to create corresponding grooves in the ground intended to receive said solid granular products, - a plurality of substantially rigid ducts (38,56,56', 138) placed behind the respective anchors (4,104), - a plurality of supports, which are integral with said frame and to which said anchors (4,104) are articulated in order to be moved between an active condition, with their lower end introduced into the ground, and an inactive condition overturned backwards, following impact against an obstacle in the ground, - controlled yielding means, which keep each anchor (4,104) in an active condition in the absence of stresses exceeding a predetermined value, which should arise when said anchor (4,104) impacts against said obstacle, - at least one tank containing said granular product to be distributed and buried, - at least one supply duct connecting said tank with each of said substantially rigid ducts (38,56,56', 138) when the corresponding anchor (4,104) is in an active condition, wherein each of said substantially rigid duct (38,56,56', 138) is articulated to said anchor (4, 104), characterized in that each of said substantially rigid duct (38, 56, 56', 138) is associated with guide means, which following said controlled yielding make it pass from an active position, in which the upper end of said substantially rigid conduit (38,56,56', 138) communicates with said supply conduit, to an inactive position, in which the upper end of said substantially rigid duct (38,56,56', 138) is decoupled from said supply duct.
