In this paper , the structure and main parameters of furrow - ridge - opener are analyzed . the soil load characteristics of the ridge - opener were measured in the soil bin ; the regression equation of the traveling force resistance was formulated . the working performace and characteristics of the water - application - furrow seeder unit were analyzed 在本文中,對起壟開溝器的結構形式及主要參數進行了理論分析,并通過土槽對起壟翼的主要性能參數進行了回歸實驗,得到了牽引阻力的回歸模型。

This series of seeders are hydraulic suspended type multi - functional machine integrating fertil - izing and intertillage management , working for deep side fertilizing and sowing in drill for the crops or wheat , cole , etc . , and deep side fertilizing , precision drilling , parallel sowing , ridge tillage , and intertillage management , etc . , for soybean , corn , beet , etc 該系列播種機為液壓懸掛式,多功能播種機,施肥、中耕管理于一機,可以進行小麥、油菜等作物的側深施肥條播作業;大豆、玉米、甜菜等作物側深施肥、精量點播、平播、壟作、中耕管理等項工作。

In this article , several evaluation methods including performance test , user survey , tracking investigation and integrated evaluation are presented to evaluate the suitability of farm machinery through the exploration and practice on machine selection experiment of no - tillage seeder , and some questions in evaluation process are put forward and the corresponding solutions are also given 本文結合免耕播種機選型試驗中,對免耕播種機進行的適用性試驗及評價方法的研究、探索和實踐,提出了采用性能試驗法、用戶調查法、跟蹤考核法和綜合評定法等方法對農機適用性進行評價,并對目前實施農機適用性評價存在的問題進行了分析,提出了相應的解決辦法。

The comprehensive seeding accuracy testing method proposed in this dissertation to test performance of precision seeder , grain drill seeder , hill - drop planter , seeding monomer , and seed sowing device is an integrative one with technology of computer vision , patter recognition , and automatic control 本文提出的適用于精密播種機、谷物條播機、穴播機,及排種器等多類型播種機具的播種精度檢測方法,是集計算機視覺、模式識別、自動控制為一體的綜合技術。

Precision seeder , grain drill seeder , hill - drop planter , seeding monomer , and seed sowing device for the first time are realize to be tested on one comprehensive test - bed , and at the same time , hard problem of evaluating seeding accuracy from seed kernel space interval is solved 該系統首次實現了對精密播種機、谷物條播機、穴播機,及排種器等多類型播種機具播種精度的檢測,解決了通過直接獲得種子粒間距而檢測播種精度這一難點問題。

Furrow - ridge - opener is the main working part of water - application - furrow seeder , the key requirement to the new design is the furrow opening , ridging , watering and fertilizing of soil completed at a time 起壟開溝器是灌水溝播機的主要工作部件,它需同時完成起壟、開溝、灌水、施肥等多項工作。

In addition , the signal of tractor ' s velocity in field is analyzed in this paper . the data and the conclusion can be used in the other study of seeder , as so on 另外因研究需要,對田間播種機作業速度進行了信號分析,其數據和分析結果可以用于其它有關播種機的研究工作。
