文档介绍：摘 要
随着当今世界经济快速发展，人们对建筑行业提出了更高的要求。以前仅靠工作人员的实践经验，对混凝泥土进行配料，从效率、质量、节约等方面已经无法满足建筑行业的发展。建筑行业向机械化、自动化、智能化发展是二十一世纪的一大目标。决定混凝土质量与效率的关键在于制造混泥土初期的配料精度，由此我们可知建筑行业拥有机械化、自动化的混凝土配料机尤为重要。
我设计的课题是PLD系列混凝土配料机。凝土配料机是一种与搅拌机配套使用的前台自动配料装置。它可以根据用户设计的混凝土配比自动完成砂、石、水泥等3～６种物料的配料程序。混凝土配料机是由给料系统、称量系统以及电气系统组成。在本设计中详细的设计了给料系统及其各部件，并对现存的各种称料系统进行了论述和比较。给料系统是配料机的重要组成部分，它能够把各种骨料输送至称料料斗中，以备称量，进行配料。称量系统是配料机中主要组成部分，它决定着各种骨料配料的精度。建筑机械的自动化大大解放了劳动生产力，减轻了工人的体力劳动，也为高速发展的房地产业，公路建设等等做出了贡献。
本设计首先配料机进行了总体设计，再而详细的设计了料斗、给料机及电动机的选择，比较了不同称量方式的称量系统，还有机架的设计。

ABSTRACT
With economic development rapidly of the world, people have put a higher requirements forwart construction industry. Concerning about batching efficiency, quality and conservation, it has been unable to meet the development of the construction by staffs`experience only. What is a major goal of the Construction industry is that to be mechannization, automation, intelligent in twenty-first century. The mixed initial accuracy determine concrete quality and efficiency of manufacturing,.So we know that the construction industry become to mechanization, automation, the concrete batching machine is especially important.
This design issue is the PLD series concrete batching machine. Concrete batching machine is a front for use as sand, automatic dosing device. It can be designed according to the user automatically match the concrete sand, stone, cement and other materials from 3 to 6 ingredients procedures. Concrete batching machine is component with feeding system, weighing system and electrical system components. It detailed design the feeding system and its components, and all the existing material systems that are discussed and compared In this design. Feeding system is an important part of batching machine, it can bring a variety of aggregate delivered to said feed hopper, ready for weighing, for ingredients. Weigh batching machine system is the main component, which determines the precision of the various aggregate in
