摘 要
圓形料場混勻堆取料機主要由可回轉(zhuǎn)的懸臂堆料機、中柱、橋式刮板（刮斗）取料機、電控系統(tǒng)等組成。中柱安裝在圓形料場的中心，中柱上部安裝有可回轉(zhuǎn)的懸臂堆料機，懸臂堆料機可繞中柱360°回轉(zhuǎn)并在變幅油缸的驅(qū)動下進(jìn)行變幅，通過回轉(zhuǎn)機構(gòu)和變幅機構(gòu)的合成運動完成堆料作業(yè)。取料機是一臺繞中往回轉(zhuǎn)的橋式刮板（刮斗）取料機，通過取料機橋梁上往復(fù)運動的料耙，將料堆物料逐層松動并撥落至料堆底部，再由刮板（刮斗）取料系統(tǒng)將已被均化的物料輸送至中柱下面的出料漏斗，通過漏斗將物料卸至地下的帶式輸送機運出堆場。
在回轉(zhuǎn)機構(gòu)中，關(guān)鍵是回轉(zhuǎn)支承。回轉(zhuǎn)機構(gòu)的工作原理是小齒輪與回轉(zhuǎn)支承的大齒輪嚙合來帶動整個回轉(zhuǎn)體的轉(zhuǎn)動，所以本文章將對回轉(zhuǎn)支承進(jìn)行選型并對小齒輪進(jìn)行設(shè)計。
圓形料場混勻堆取料機是一種理想的散狀物料均化設(shè)備，適用于大型水泥廠的原料預(yù)均化，也廣泛應(yīng)用于煤炭、電力、冶金、化工、港口等行業(yè)需要對散狀物料進(jìn)行存貯，均化的堆場。
關(guān)鍵詞：取料機；橋式刮板；回轉(zhuǎn)機構(gòu)
ABSTRACT
Circular stockyard blending stacker-reclaimer is mainly composed of rotatable boom stacker, central pillar, bridge-type scraper (scraping bucket) reclaimer., and electric control system. The central pillar is installed in the center of circular stockyard. The top of the central pillar is equipped with rotatable boom stacker, which can rotate 360° around the central pillar, change its amplitude when driven by the derricking cylinder, and finish material stacking through the synthesis movement of slewing mechanism and luffing mechanism. The reclaimer is a bridge-type scraper (scraping bucket) reclaimer which rotates around the central pillar. It loosens the stacking materials in the material pile layer by layer and get them to the bottom of the material pile through the material rake which moves back and force on the reclaimer bridge. Then the scraper (scraping bucket) reclaiming system transports the blended materials to the discharging hopper below the central pillar through which the materials are discharged to the belt conveyor and then conveyed out of the stockyard.
In the slewing mechanism,the key is the rotor support. The theory is the action between the rotor support and the pinion,so this paper chooses the rotor support and designs the pinion.
Circular stockyard blending stacker-reclaimers are a kind of ideal bulk material blending equipment which apply to preblending of raw materials in large cement plants. Besides, they are widely used in stockyards where storage and blending of bulk materials are needed in industries such as coal, power, metallurgy, chemical and port.
