Abstract
The invention discloses a special-shaped staggered push wheel sieve mechanism. The special-shaped staggered push wheel sieve mechanism comprises a rack and a plurality of rotating shafts arranged on the rack side by side, wherein the center lines of the rotating shafts are parallel to one another; a plurality of push wheel components with elliptical cross sections are arranged on the outer diameters of the rotating shafts in a sleeving mode, each pull wheel component is provided with a plurality of gear rings along the axial direction, and the sizes of the pull wheel components of each -rotating shaft are gradually reduced in sequence along the axial direction of the corresponding rotating shaft; the size reducing directions of the pull wheel components on every two adjacent rotating shafts are opposite, the pull wheel components are engaged with one another, and a clearance is further formed between engaged parts. The special-shaped staggered push wheel sieve mechanism can provide axial and radial overturning for the crushing sieving mechanism of a sieving machine, so that the dispersing degree of materials is improved, meanwhile the gear clearance of a crushing mechanism can be adjusted, and thus the sieving level of the materials is adjusted; in addition, the mechanism can be convenient to disassemble and replace.
Description
?
Technical field
The invention belongs to mine mechanism technical field, particularly relate to the sieving and grading of the industry solid materials such as ore dressing, building materials, electric power, light industry and chemical industry.
Background technology
Dry classification many employings drum-type grid sieve of coal, reciprocating grid sieve, probability screen and inertia vibrating screen in current colliery, coal washing and thermal power plant.Drum-type grid sieve nest is long-pending large, and screening face is little, and energy consumption is large, and noise is large, product technology is backward, is not inconsistent with existing national industrial policies; Reciprocating grid sieve drives the classification of material by the reciprocating motion of sieve, the speed of service of material is slow, and screening efficiency is low; Inertia vibrating screen makes to be positioned at inclined-plane sieve plate material generation exciting by the exciting force that vibrating motor produces and makes material movement, and the sieve plate simultaneously by being covered with sieve aperture carrys out stock grading; It is low all to there is screening efficiency in above-mentioned screening plant, the shortcomings such as sieve aperture easily blocks, and energy consumption is high, screening noise is large and plant maintenance is difficult, and supporting equipment is adopted damage, can say that the screening of material seriously restricts the development of all departments, all use of the said equipment that used has these puzzled per family.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of special-shaped alternating expression thumb wheel screening mechanism, can be more effective in material screening, avoids solid accumulation to block, maintenance convenient disassembly.
Technical scheme: for solving the problems of the technologies described above, the present invention by the following technical solutions: a kind of special-shaped alternating expression thumb wheel screening mechanism, comprise frame and be located at several rotating shafts in frame side by side, the center line of described rotating shaft is parallel to each other; On the external diameter of described rotating shaft, cover has multiple cross sectional shape to be oval thumb wheel component, and described thumb wheel component is provided with multiple gear ring vertically and size reduces successively along the axis of rotating shaft; It is contrary that thumb wheel scantling in described adjacent shafts reduces direction, and engage each other between thumb wheel component, and engagement is also provided with gap between position.
Material selection rigid plastics or the vulcanie of described thumb wheel component are made.
On described spindle outer diameter, the outermost two ends of thumb wheel mechanism are provided with wheel, are fixed by thumb wheel.
Beneficial effect: compared with prior art, the present invention has the following advantages: can provide axially and the upset of warp-wise for the crushing and screening mechanism of screening machine, improve the degree of scatter of material, can adjust crushing mechanism gear clearance simultaneously, thus the graduation of instrumentality material screen; In addition can for convenience detach and replacing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in accompanying drawing 1 ~ 4, a kind of special-shaped alternating expression thumb wheel screening mechanism, comprise frame and be located at several rotating shafts in frame side by side, the center line of described rotating shaft is parallel to each other; On the external diameter of described rotating shaft, cover has multiple cross sectional shape to be oval thumb wheel component, and described thumb wheel component is provided with multiple gear ring vertically and size reduces successively along the axis of rotating shaft; It is contrary that thumb wheel scantling in described adjacent shafts reduces direction, and engage each other between thumb wheel component, and engagement is also provided with gap between position.Material selection rigid plastics or the vulcanie of described thumb wheel component are made.On described spindle outer diameter, the outermost two ends of thumb wheel mechanism are provided with wheel, are fixed by thumb wheel.
During work, rotating shaft drives thumb wheel to rotate, because thumb wheel component is that joint one joint is enclosed within rotating shaft, while radial upset being produced to material during rotation, owing to adopting indenting thumb wheel to make material to roll vertically, thus Effective selection material more, and avoid the accumulated plugging of material.When needs overhaul, directly unclamp wheel, get final product for convenience detach or change corresponding thumb wheel component.
