Polygonal drum type tobacco stem grading and screening machine

Abstract

The invention discloses a polygonal drum tobacco stalk grading and screening machine, which aims at providing a polygonal drum tobacco stalk grading and screening machine with convenient maintenance.The utility model comprises a frame, a cover body and a screen cylinder. A group of supporting rollers are respectively arranged at two ends of the upper part of the machine frame; At one end of thatframe, a speed reduce motor for driving the side support roller is arranged; The screen barrel comprises a front barrel body, a rear cylinder, a plurality of cross beams, a plurality of clasp rings arranged at intervals along the longitudinal direction of the cross beams and fixedly connected with the cross beams, a broken stem orifice plate assembly, a short stem orifice plate assembly and a longstem grid assembly sequentially detachably connected with the cross beam from the front end to the rear end of the cross beams, and a plurality of sets of plate copying assemblies respectively installed on the cross beams and facing the center of the screen cylinder; A forward rolling ring engaging with the side supporting roller is arranged on the outer wall of the front cylinder, and a backwardrolling ring engaging with the side supporting roller is arranged on the outer wall of the rear cylinder. After the forward roller ring and the backward roller ring are engaged with the correspondingsupporting roller, the screen cylinder is inclined with a high front end and a low rear end.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to a polygonal drum type tobacco stem grading and screening machine. Background technique [0002] In the field of leaf threshing and redrying, many enterprises use vibrating screens supplemented by conveyors, or use five-sided sieves to sieve tobacco stems. Vibrating sieves have disadvantages such as large floor area, easy blockage of screen holes, and difficulty in cleaning. Five-sided sieve roll tobacco stem sorting machine (patent number: CN201110285997.6) The axis across the center and the surrounding spoke struts result in complex sieve roll structure, inconvenient transmission mode, poor manufacturing process, screen plate replacement and cleaning of the sieve cylinder Tobacco stem residues and powder are relatively difficult, and the maintenance of the entire sieve cylinder is poor, and there is even a risk of being blocked when the stems are turned out of the ho...
