MATERIAL DISTRIBUTION DEVICE FOR AGRICULTURAL MACHINES Russian patent published in 2021 - IPC A01C7/04 

FIELD: agriculture.

SUBSTANCE: device (100) contains chamber (110) having inlet hole (105) and outlet hole (106) for distributed material, pneumatic means for generation of pressure change inside chamber (110), rotary distributing element (120) separating chamber (110) into two compartments (111, 112). First compartment (111) communicates with inlet hole (105) and outlet hole (106) of chamber (110), and second compartment (112) communicates with pneumatic means via fluid. First and second compartments (111, 112) are separated with a gasket. Rotary distributing element (120) is made with the possibility of receiving material based on a value of pressure inside chamber (110) and transporting it from inlet hole (105) to outlet hole (106) of chamber (110). Device (100) for distributing contains at least one sensor (310, 320) made with the possibility of detecting a parameter indicating a hydraulic seal between first and second compartments (111, 112). A seeding machine contains above-described device (100) for distributing material.

EFFECT: constant monitoring of the state of the hydraulic seal between two compartments of the distribution device is provided.
