FIELD: agricultural equipment.
SUBSTANCE: material distribution device for an agricultural machine contains a chamber with an inlet and an outlet for distributed material, pneumatic means for generation of change in pressure inside the chamber, a rotary distributing element placed in the chamber and made with the possibility of reception of material based on a value of pressure inside the chamber and its transportation from the inlet to the outlet of the chamber, wherein the rotary distributing element divides the chamber into two compartment – the first and the second ones. The distribution device also contains a pressure sensor placed in direct communication with the second compartment of the specified chamber in direct communication with pneumatic means via fluid. At the same time, the specified pressure sensor is made with the possibility of measurement of a value of pressure inside the chamber, and it is connected to a control unit made with the possibility of reception from the specified sensor of a signal representing the value of pressure inside the chamber. The control unit is connected to an optical and/or acoustic warning device made with the possibility of being activated, if the value of pressure inside the chamber, measured by the pressure sensor, differs from the set threshold value (Pth).
EFFECT: invention will allow for an increase in the efficiency of informing a user about improper functioning leading to improper seed distribution on the soil.
