摘要：
FIELD: dosing devices.SUBSTANCE: invention relates to dosing devices and can be used for dispensing a scrap-and-air mixture. Dispenser comprises hopper (1) tapered downwards with a discharge hole. On the bottom of hopper (1) there is shaft (4) with a transporting spiral made in the form of screw (2) and a drive. Screw (2) is arranged in casing (3). Above screw (2) an adjusting flap is mounted in order to change the amount of fed scraps having a graduation corresponding to a set flow rate of the scraps. Flap has an adjusting screw mechanism for changing the size of a window above screw (2). In the lower part of casing (3) of screw (2) sieving window (8) is made. Sieving window (8) is connected to inclined pipeline (9) and is hermetically connected to pressure pipeline (10) of high-pressure fan (11) in order to form mixing chamber (12). Behind mixing chamber (12) there is screw swirler (13) of the flow connected by scraps pipeline (17) with a plant for the subsurface intrusion of fertilizers or meliorants.EFFEC
