Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1-3, an alternative blanking device on a bag-type dust collector comprises a hopper outlet 1, a blanking fixing plate 2 is fixed below the hopper outlet 1, blanking ports 21 are annularly arrayed in the middle of the blanking fixing plate 2, a shutter shaft 3 penetrates through the center of the blanking fixing plate 2, a shutter 5 is fixed at the upper end of the shutter shaft, a gear 4 is fixed at the lower end of the shutter shaft, shutter blanking ports 51 corresponding to the blanking ports 21 are annularly arrayed on the shutter 5, two guide chutes 7 are arranged at the eccentric position of the lower end face of the blanking fixing plate 2, pull rods 6 capable of freely moving along the length direction are arranged in the guide chutes 7, racks 61 meshed with the gear 4 are arranged at the head ends of the pull rods 6, and the tail ends of the pull rods are fixed on an air cylinder 8; divide feed bin 9 to pass through the pipe connection in the below of unloading fixed plate 2, be equipped with left feed opening 91 and right feed opening 92 respectively in the lower part left and right sides of this branch feed bin 9, the horizontally pivot 93 is in the antetheca of this branch feed bin 9 and its one end passes through feed bin 9 and is connected with handle 95, and the other end setting is on the back wall of dividing feed bin 9, and branch flitch 94 is in the inside of branch feed bin 9 and one end is fixed on pivot 93, and this branch flitch 94 can be closed in proper order left feed opening 91, right feed opening 92. The pull rod 6 and the gate plate 5 are in a gear-rack meshing transmission mode, so that the linear motion mode of a piston rod of the air cylinder 8 is converted into the rotary motion mode of the gate plate 5. The staff can reach the purpose of switching the feed opening by controlling the handle 95 to realize the alternate feeding function.
