Bridge-type scraper reclaimer

Abstract

The invention provides a bridge-type scraper reclaimer which comprises a rack and rakes symmetrically arranged on the two sides of the rack. One ends of the rakes are connected with the rack through connecting mechanisms, and the other ends of the rakes are rotationally supported on tracks of the rack through rollers arranged at the lower ends of the rakes. The rakes are driven by a rake driving mechanism to reciprocate on the tracks, so that the rakes conduct pitching motion around the tracks while swinging around the joints of the connecting mechanisms and the rack. The rakes are supported on the tracks of the rack through the rollers and connected with the rack through the connecting mechanisms, and the rakes are driven by the rake driving mechanism to move along the tracks; due to the fact that the length of the connecting mechanisms is kept unchanged, the rakes conduct curvilinear motion inside the horizontal plane and the vertical plane, component force for scraping materials downwards is generated for material piles, materials slide down uniformly, and the production capacity is balanced. According to the bridge-type scraper reclaimer, a travelling car is not needed any more, the supporting weight of a girder is reduced, the needed strength and rigidity are smaller than those of an existing reclaimer, and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a bridge type scraper reclaimer. Background technique [0002] Bridge-type scraper reclaimer is widely used in steel, building materials and energy industries because of its advantages of good homogenization effect, large reclaiming capacity and simple structure. In the existing bridge-type scraper reclaimer, most of the rakes are installed on both sides of the moving trolley. The moving trolley moves on the main beam under the action of the power mechanism and drives the rake to move along the main beam. The structure of this structure The rake driving structure of the bridge-type scraper reclaimer has a complex structure and high manufacturing cost, and the rake and the trolley are supported on the main girder together, which requires high rigidity and strength of the main girder, which increases the manufacturing cost of the main girder. Moreover, the rake can only move in a straight line, and has only horizontal force on t...

Problems solved by technology

In the existing bridge-type scraper reclaimer, most of the rakes are installed on both sides of the moving trolley. The moving trolley moves on the main beam under the action of the power mechanism and drives the rake to move along the main beam. The structure of this structure The rake drive structure of the bridge-type scraper reclaimer has a complex structure and high manufacturing cost, and the rake and the trolley are supported on the main girder together, which requires high rigidity and strength of the main girder, which increases the manufacturing cost of the main girder

Moreover, the rake can only move in a straight line, and only exerts horizontal force on the material, which may easily cause uneven falling of the material

The rake and the trolley move together on the main girder, resulting in a large power consumption of the trolley and a waste of energy
