Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings; a rotary swing double-acting slow feeder comprises a hopper 1, an upper sleeve 4, a lower sleeve 14, a rotary swing device, a collision blanking device and a feeding trough 10; the hopper 1 is arranged at the center of the fixed frame 3 through two symmetrical upper connecting lug plates 2; the upper sleeve 4 is fixedly arranged in the middle of the fixed frame 3 through two semi-circular ring pieces 17 and two lower connecting lug plates 13 which are symmetrically arranged, is positioned below the hopper 1 and is kept on the same central line with the hopper 1; the lower sleeve 14 takes the geometric center line of the fixed frame 3 as an axis, three fixed ends 15 are sequentially arranged at intervals of 120 degrees to be fixed with the upper sleeve 4, and the diameter of the lower sleeve 14 is designed to be 152mm and is 42mm larger than that of the upper sleeve 4 according to the characteristic of the repose angle of the material and the distance between the upper sleeve 4 and the lower sleeve 14; the rotary swing device is assembled in the center of a gap between the upper sleeve 4 and the lower sleeve 14 and comprises a rotating shaft 16, a rolling bearing 6 and a swing rod 7, wherein the rolling bearing 6 is connected with the rotating shaft 16 and is arranged in a track 5 preset between the upper sleeve 4 and the lower sleeve 14; the collision blanking device is fixed below the lower sleeve 14 and comprises a bottom plate 12, a bottom plate extending shaft 11 and a collision wheel 8, wherein the bottom plate 12 is connected with the swing rod 7, is installed below the lower sleeve 14 and keeps a distance of 10mm with the bottom end of the lower sleeve 14, the diameter of the bottom plate 12 is 172mm and is larger than the diameter of the sleeve 14 by 20mm, and the bottom plate extending shaft 11 is fixedly connected with the collision wheel 8.
