自动滚筒选沙机的结构设计

摘要

在建筑材料中，人们把水泥、沙子与石子加水搅拌口凝结硬化成的石

头样的东西叫做混凝土，它在建筑中非常重要，它的质量直接决定施工的

成败。集料在普通混凝土中构成混凝土的骨架。集料在宏观上分为粗集料

和细集料，人们通常以 5mm 为分界，细集料亦称为沙子，沙子的获取通常

通过筛分法获得，工程中常用细度模数把沙子划分为粗沙，中沙，细沙，

大力开展建筑机械化，逐步提高建筑自动化水平，对发展建筑业，改

变建筑业的技术与装备落后面貌，多快好省地完成各项工程建设，特别是

国家重点工业建设，促进国家经济发展，具有十分重要的意义。

建筑物是人类所必需的，走进大都市，给你的第一感觉那就是四处林

立的高楼大厦。建筑工业化的发展程度往往反映了这个国家的现代化程度。

而建筑机械化，自动化是建筑工业化的重要标志。

本设计从建筑自动化角度出发，摒弃了从前各种人工方法，采用小车

式自动筛沙法。由电动机驱动，集挖沙、筛沙为一体，减小操作空间和劳

动强度，并且大大提高了劳动生产率。

由于本设计没有任何参考，一切从基点开始，从手册中一一查取标准

Building the necessary human, into the city, you feel that the first four

forest of tall buildings. The degree of development of industrialized construction

often reflects the country's modernization. The construction of mechanization

and automation is an important indicator of industrial construction.

In civil engineering and construction and installation process, maximizing

the use of mechanization and automation to replace manual, not only can save a

lot of manpower and reduce labor intensity of workers, who take on difficult

human completed, the difficult construction, but also significantly Improving

labor productivity and accelerate the construction speed, ensure project quality,

reduce costs and improve the economic and social benefits.

In building materials, the people of the cement, sand and stone mixed with

water into the mouth condensation sclerosis stone kind of thing is called

concrete, it is very important in the construction, which directly determine the

quality of the success or failure. In ordinary concrete aggregate in a concrete

skeleton. At the macro on aggregate divided into coarse aggregate and fine

aggregate, people usually 5 mm as a dividing line, fine aggregate, also known as

sand, the sand is usually obtained through the screening method available,

commonly used in the project module fineness of the sand For the grit, sand,

sand, in particular sand. The particle size of sand directly determine the quality

of the concrete, but sand in the screening project is an important step in the

from January 1 to obtain manual standard parts, greater workload, coupled with

the level of my limited time constraints, it is difficult to distinguish from the

structure of the degree of perfection, you look more teachers Correction.

Key words mechanization; automatically; sieve sand
