Embodiment Construction

[0013] Referring to the accompanying drawings, a rake mechanism for loose materials on a screw reclaimer includes a rake 1, a winch mechanism 2, a four-wheel assembly 3, a two-wheel assembly 4, a rake bracket 5, and a rack and pinion drive Device 6, box girder 7, rack 8, driving device 9, driving gear 10, motor 11, the rake 1 is hinged with the rake bracket 5 at the bottom beam, and the upper part of the rake 1 is fixed on the rake bracket 5 The hoisting mechanism 2 above is used to adjust the pitch angle, and the rake support 5 adopts a statically definite truss structure. The four-wheel assembly 3 and the two-wheel assembly 4 fixed on the rake support 5 are driven by the rack-and-pinion transmission device 6. Drive the material rake 1 to reciprocate to complete the work of loosening the material; the transmission device of the material rake mechanism is a rack and pinion transmission device 6, the rack 8 is fixed on the side of the box beam 7, and the driving device 9 is fixe...

Abstract

A material rake mechanism arranged on a spiral material picking machine and used for loosening materials comprises a material rake, a hoisting mechanism, a four-wheel assembly, a two-wheel assembly, a material rake bracket, a gear-rack transmission device, a box beam, a rack, a driving device, a driving gear and a motor. The positions, at a bottom beam, of the material rake and the material rake bracket are hinged, the pitching angle of the upper portion of the material rake can be adjusted through the hoisting mechanism fixed to the material rake bracket which is of a statically determinate truss structure, and the material rake is driven to move back and forth by the gear-rack transmission device through the four-wheel assembly and the two-wheel assembly which are fixed to the material rake bracket so that material loosening work can be completed. The gear-rack transmission device serves as a transmission device of the material rake mechanism, and the rack is fixed to the side face of the box beam. The material rake mechanism is novel and simple in design thought, the steel structure is definite and reasonable in stress and low in weight, the gear and rack transmission mode is easy, the economical and reliable effect is achieved, the cost is reduced, and the material rake mechanism is applied to the technical fields of metallurgy, electric power, chemical industry, coal, papermaking, building materials and the like.

Description

technical field [0001] The invention relates to a material rake mechanism used for loose materials on a screw reclaimer in the technical fields of metallurgy, electric power, chemical industry, coal, papermaking, building materials and the like. Background technique [0002] At present, the main traveling mechanism of the conventional material rake mechanism adopts double-track operation, the steel structure is complex, the installation is difficult, the welding volume is large, the weight is large, and the cost is high. Therefore, researching and developing a kind of material rake mechanism that is used for loose material on the screw reclaimer is the new problem waiting to be solved urgently. The existing material rake mechanism design adopts the concept of small stroke and large material rake, mainly for coal, ore, limestone, etc. with good fluidity and high density, but for wood chips, wood chips, and straw with poor fluidity and high density, a large stroke needs to be ...
