Dough divider for cutting a mass of dough into pieces of dough, comprising a frame in which are provided: - a bowl for containing a quantity of dough with an access opening and a bottom, - a dividing device with a grid consisting of cutting blades for dividing the mass of dough, present on the bottom of the bowl, into pieces of dough, - a drive device for moving the bottom and the grid relative to each other in a substantially vertical direction to allow the cutting blades of the grid to be pushed through the mass of dough so as to form the pieces of dough, wherein the bottom and the grid can extend substantially parallel to each other and can be moved between a remote position in which the mass of dough can rest on the bottom of the bowl without the cutting blades passing through the mass of dough, and a raised position in which the cutting blades pass through the mass of dough when the latter rests on the bottom of the bowl, wherein the drive device comprises at least two arms (14a,14b,15a,15b) placed between a support structure secured to the frame and a driven structure, wherein this driven structure is supported by an upper end of a first arm (14a,14b) and an upper end of a second arm (15a,15b) and comprises the bottom of the bowl or said grid, said arms (14a,14b,15a,15b) intersecting on a pivot shaft and being interconnected such that they can pivot around said shaft, wherein drive means are provided making it possible to approach or move away one end of the first arm (14a,14b) relative to one end of the second arm (15a,15b) in order to raise or lower said driven structure to move the bottom and the grid between the raised position and the remote position. - a bowl for containing a quantity of dough with an access opening and a bottom, - a dividing device with a grid consisting of cutting blades for dividing the mass of dough, present on the bottom of the bowl, into pieces of dough, - a drive device for moving the bottom and the grid relative to each other in a substantially vertical direction to allow the cutting blades of the grid to be pushed through the mass of dough so as to form the pieces of dough, wherein the bottom and the grid can extend substantially parallel to each other and can be moved between a remote position in which the mass of dough can rest on the bottom of the bowl without the cutting blades passing through the mass of dough, and a raised position in which the cutting blades pass through the mass of dough when the latter rests on the bottom of the bowl, wherein the drive device comprises at least two arms (14a,14b,15a,15b) placed between a support structure secured to the frame and a driven structure, wherein this driven structure is supported by an upper end of a first arm (14a,14b) and an upper end of a second arm (15a,15b) and comprises the bottom of the bowl or said grid, said arms (14a,14b,15a,15b) intersecting on a pivot shaft and being interconnected such that they can pivot around said shaft, wherein drive means are provided making it possible to approach or move away one end of the first arm (14a,14b) relative to one end of the second arm (15a,15b) in order to raise or lower said driven structure to move the bottom and the grid between the raised position and the remote position.
