1. An agricultural spreading machine comprising:
a storage hopper for storing chemical granules; and
a portioning apparatus for generating granulate portions generated from the granules,
a conveying device that conveys the granules from the storage hopper into the portioning apparatus, wherein the conveying device generates a conveying air stream entraining the granules and comprises a blower to generate the conveying air stream;
a dosing device that adjusts a granulate quantity fed to the portioning apparatus;
a depositing device that deposits the generated granulate portions onto an agricultural land surface;
wherein the portioning apparatus includes an inlet opening for the granules and an outlet opening to dispense granulate portions generated from the granules and a rotationally driven conveying element is configured to bring the granules introduced into the portioning apparatus together as granulate portions during a rotational movement,
wherein the granulate quantity and a size of a granulate portion is adjusted via the granulate quantity fed to the portioning apparatus;
wherein the portioning apparatus comprises a housing, inside which a portioning chamber is disposed, wherein the conveying element is disposed inside the portioning chamber and the portioning chamber is connected to an inlet channel via a chamber inlet opening and the conveying air stream entraining the granules is conveyed via the chamber inlet opening into the portioning chamber; and
wherein the chamber inlet opening is arranged at a lateral end face of the portioning chamber and is aligned in a direction of rotation of the conveying element, so that the conveying air stream is introduced into the portioning chamber in the direction of rotation of the conveying element.
