1G-100型水旱兩用旋耕機設計
摘 要: 水旱兩用旋耕機具有體積小，重量輕，性能好，操作容易，轉(zhuǎn)動方便，適應性廣，價格合宜，水旱兩用旋耕機機動靈活，一般中小型機械廠、農(nóng)機廠均可生產(chǎn)制造的要求。如果設計成功,本機可進行旱田旋耕、水田耙整等項作業(yè)，能彌補現(xiàn)有旋耕機存在功能較單一、生產(chǎn)效率偏低等不足之處。
我設計的是一臺水旱兩用旋耕機，與黃海－12（15）馬力手扶拖拉機相匹配，主要用于水田耕整，也可進行旱田耕作?，F(xiàn)有的水旱旋耕機是耕幅為0.6米的老式機型，而本課題設計的水旱旋耕機耕幅為1米。
本設計與黃海－12（15）馬力手扶拖拉機相匹配，中間傳動，固定聯(lián)接。設計內(nèi)容包括機架、傳動系統(tǒng)、刀輥、尾輪等，要求結(jié)構簡單、緊湊、重心平衡。該機可用于水田耕整地，也可進行旱田旋耕。各項性能指標應達到國家標準和農(nóng)藝要求。通過對水田旋耕機驅(qū)動輪與土壤相互作用的力學特性的分析，結(jié)合水田土壤的力學性質(zhì)，經(jīng)過優(yōu)化設計，研制水旱兩用旋耕機驅(qū)動輪，使該驅(qū)動輪具有良好的動力性能。

關鍵詞: 水田旋耕機；創(chuàng)新設計；驅(qū)動輪性能

Design of 1G-100-floods, droughts and dual-use Rotary machine
Abstract:The floods, droughts and dual-use Rotary machine has small size, light weight, performance, and easy to use, easy rotation. it wide adaptability and affordable. Floods, droughts and dual-use rotary machine has tiller-mobile and flexible.Small and medium-sized general machinery factory. The agriculture of factories can manufacturing requirements. If it can successful design, this machine can be floods and drought rotary,and it can rake the whole paddy field’s operations. It can to cover the existing functions of a rotary-existence’s single and low production efficiency, such as inadequate.
I design is one of the floods, droughts and dual-use rotary tiller machine, and it matchs with the Yellow Sea -12 (15) horsepower walking tractor.It not only mainlies for rotary of paddy field, but also for upland farming. The existing floods, droughts and dual-use rotary tiller machine’s rate is the 0.6-metres site in the old models, but the issue of floods, droughts and Rotary machine’s design for the 1-meter site.
   The design mach with the Yellow Sea -12 (15) horsepower walking tractor . It makes the middle transmission and fixed link. The design elements include rack, drive system, knife rolls, round tail and so on. It requires frame simple and compact,and it requires the focus of balance. The aircraft not only can be used for paddy’s rotary and formation, but also for upland Rotary. Various performance indicators should meet the state standards and agronomic requirements. Through the driving wheel of paddy fields Rotary interaction with the mechanical properties of the soil analysis, combining the mechanical properties of the soil of paddy field, optimized design, development of floods, droughts and dual-use rotary tiller-driving wheel, so that the driving wheel has a good dynamic performance.

Key words: Floods, droughts and dual-use rotary machine; innovative design;the performace of driving wheel
