Aiming at the problem of reduced and leakage tillage when commonly used rotary cultivator worked in the or-chard can’ t work in the area between the trees and need secondary repair tillage.Put hydraulic obstacle avoidance sys-tem to the orchard farming and design an orchard obstacle avoidance rotary cultivator.Through theoretical analysis and calculation, the working parameters of the rotary cultivator was determined, each system and main working parts were de-signed, then the structure and technical parameters of the machine were determined.The orchard avoidance rotary tiller is simple but reliable, has good economic value and promotion prospects.

针对南疆气候特点和土壤物理特性，以土壤可持续利用为目的，设计一种悬挂翻转式深翻犁，通过深翻耕作，改善土壤物理结构，增加作物根系生长深度，确保作物持续增产。用具有双层主副犁结构的深翻犁进行耕作时，不仅能将耕作层含病菌的土壤、杂草、越冬虫卵翻入主犁开出的沟底，解决土壤含病菌的状况，还可减小单个犁体翻垡阻力，降低拖拉机功耗。

Moisture regain of seed cotton is an important indicator in monitoring processing quality of cotton.Through on-line measurement of Moisture regain of seed cotton, we can effectively control the drying equipment to regulate the tem-perature in proper time, and make the modern cotton processing smarter and more efficient.In this paper, we adopt near-infrared measurement of seed moisture to design an on-line monitoring system.By the rapid non-contact detection, we can quickly and accurately measure the moisture regain of seed cotton, which will provide accurate regulation parameters for the subsequent drying equipment in cotton processing.
