FEEDER-METERING DEVICE OF LOOSE MATERIALS |
摘要 |
FIELD: machine building. ^ SUBSTANCE: feeder-metering device of loose materials consists of converging receiving hopper with unloading branch, of installed on bottom of hopper shaft with transporting spiral and of drive. The transporting spiral corresponds to a cylinder compression spring tied with the shaft by means of two bushings each equipped with a lock member-clamp. The feeder consists of a mechanism of change of lead of a spiral turn; the mechanism is positioned on a driven shaft and divides the spiral into a transporting and a metering sections. The mechanism of change of lead of a spiral turn is made as two-shoulder lever; it is installed in a lengthwise through slot by means of the axle and can perform a restricted turn in plane of the slot. Also shoulders of the lever on their ends are equipped with rollers with a circular radial groove; the rollers interact with a spiral turn. On the side opposite to the drive a free end of the shaft corresponds to a journal with profile surface facilitating rotation of the shaft when a turn lead of the transporting and metering sections of the spiral is changed for adjustment. ^ EFFECT: raised reliability and expanded range of efficiency adjustment during supply of loose material. ^ 2 cl, 3 dwg |
