2、装置是中部槽，刮板链安装在中部槽的槽面。中部槽沿运输路线全线铺设，刮板链绕经机头、机尾的链轮接成封闭 形 置于中部槽中，与滚筒采煤机和输送机推移装置配套，实现落煤、装煤、运煤及推移输送机械化。 沿 输送机全长都可向溜槽中装煤，装入中部槽中的煤被刮板链拖拉，在中部槽内滑行到卸载端卸下。 刮板输送机主要优缺点是： 优点 : 1、结构坚实。能经受住煤 炭、矸石或其他物料的冲、撞、砸、压等外力作用。 2、 能适应采煤工作面底板不平、弯曲推移的需要，可以承受垂直或水平方向的弯曲。 3、机身矮，便于安装。 4、能兼作采煤机运行的轨道。 5、可反向运行，便于处理底链事故。 6、能作液夜支架前段的支点。 缺点
3、 : 1、空载功率消耗较大，为总功率的 30%左右。 2、不宜长距离输送。 3、易发生掉链、跳链事故。 4、消耗钢材多。成本大。 刮板输送机是与大型综采工作面设备配套使用的液压支架、采煤机，完成把工作面采煤机采下的煤输送、转运到后续 运输 设备上的任务 ， 并提供相应的连接手段。本刮板输送机与 MG300/700-WD 采煤机配套使用，运量可达 1000t/h，技术先进，工作可靠，是大型综采配套设备的优秀机型 . 河北工程大学机电学院毕业设计 2 Scraper conveyor is a kind of flexible traction in the continuous conveyin
4、g machinery, is the coal face and the coal mining area of roadway layout of machinery. Various types of scraper conveyor of the main structure and composition of the basic components are the same, it is by the head, middle and tail of three machine parts. In addition, for over conveyor equipment use
5、d hydraulic jacks and tight chain tight when the subsidiary components such as chains. Machine head by the head frame, motor, fluid coupling, reducer, such as pieces of the composition and sprocket. The transition from the central trough, the central groove, scraper chain and the composition of such
6、 pieces. Rear scraper plane for the return of the device chain. Traction mechanism is a scraper chain, bearing device is the middle trough of scraper chain, mounted in the middle groove groove face. The central groove along the transport route laying across the board, a scraper chain around the nose
7、, tail sprocket connected into a closed shape in the middle groove, and drum shearer and the conveyor over devices, implementation of falling coal, coal, coal and passage transport mechanization. Conveyor along the full length has to be in coal chute, into the middle groove in coal scraper chain dra
8、g, in the central groove sliding to unload unloading terminal. Scraper conveyor What is advantages and disadvantages? Scraper conveyor is the main advantages and disadvantages: advantages: 1. The structure of a solid can withstand coal, waste or other materials of red, hit, hit, pressure and other e
9、xternal force. 2.It is able to adapt to uneven floor coal face, bending over the need for vertical or horizontal can withstand the bending direction. 3, body short, easy to install. 4, can act as Shearer orbit. 5, can reverse run, easy to deal with the accident at the end of chain. 6, fluid can be t
10、he fulcrum of the preceding night stand. Disadvantages: 1, no-load power consumption of a greater power for the total about 30%. 2, not long-distance transmission. 3, prone to swap chain, jumped the accident chain. 4, consumption of steel and more costs. Scraper conveyer with large fully mechanized
11、face equipment supporting the use of the hydraulic support, shearer, completion of the work face coal mining machine mining under the coal transport, transport to the subsequent transport equipment on the task, and to provide the corresponding connection means. The scraper conveyor and MG300 /700-WD coal mining machine, the volume can reach1000t / h, advanced technology, reliable work, large fully mechanized mining equipment of the best model.
