设计简介
摘 要
本文所设计的ZBJ1000型制钵机是用来生产在农业生产中广泛使用的育秧钵。育秧钵的钵体由配有各种肥料的土壤做成圆柱状，上端有一凹孔，用来播种种子。用育秧钵进行育苗和移栽，能够保证种子有足够养料以及种子成苗后可以方便的移栽到田间，种子发芽率、成活率高，苗体强壮且防虫害。ZBJ1000型制钵机，吸取了前人研究成果的精华，与手工制钵和过去的制钵机不同的是，ZBJ1000型制钵机具有生产率更高，结构更简单，操作更方便，基本实现自动化，性价比高等优点；提高了生产效率并可实现大规模生产，可以保证秧苗早育、早熟、早上市，同时还能节约劳动力、种子、肥料、农药等。
本文从ZBJ1000型制钵机的工作原理、运动协调、总体结构、运动和尺寸等多方面进行了说明和分析。
关键词：制钵机、育秧、运动分析、营养钵。
Abstract
ZBJ1000 earthen bowl machine ,which is designed in this text ,is used to produce the seedling bowl ,which is very popular in the agricultural produce .The seedling bowl is made as a cylinder by the nutritional soil ,which consists of all kinds of fertilizer .And there is a cave pit in the top of the bowl , which is the very hole we put the seedling in .Growing and transplanting the seeds in this bowl can make sure the seeds have enough time and nutrition to grow with ,high germination rate ,high survival rate ,strong and anti-pest.
ZBJ1000 earthen bowl machine ,differently from the former machine ,has lots of benefits just like :higher production ,easier structure ,more convenient handling ,automation and economy .Besides it can realize the earlier growth ,earlier maturity ,earlier on market , and it can economy labor force ,fertilizer and agrochemical at the same time.
This text is going to introduce the ZBJ1000 earthen bowl machine about its structure ,motion ,work principle and size.
Keywords：earthen bowl machine 、nursery 、kinematical analysis 、bowl.
