The utility model relates to an air-suction cotton precision hole seeder which can complete precise seeding and other operations at one time. The device mainly comprises a duck mouth, a drum seed inlet, a seed brush, a seed separator, an air suction hole, a seed suction port, an air suction port, a vacuum chamber, a seed chamber, a seed scraper, a cleaning brush and a gas breaker. During the operation, a fan generates negative pressure in the air chamber, and seeds are adsorbed on the seed suction hole of the seed extraction tray. When the seed moves to the seed drop area, the air-breaking block blocks the stomata, and the negative pressure disappears, and the seed is separated from the suction hole of the seed tray to achieve one seed throwing. The seed falls into the seed canal under the combined action of gravity, rolling along the seed canal and falling into the inner cavity of the duck's mouth. While the duck's mouth breaks into the soil and opens the hole, the moving duck's mouth is forced to open, and the seed falls into the bottom of the hole rapidly. The air-suction cotton precision hole seeder has the characteristics of high production efficiency, low labor intensity, compact structure and convenient movement.
【技术实现步骤摘要】
气吸式棉花精量穴播器所属
本专利技术涉及一种能够一次性完成对棉花的精确播种作业的一种气吸式棉花精量穴播器。
技术介绍
棉花,是锦葵科棉属植物的种子纤维,原产于亚热带。植株灌木状,在热带地区栽培可长到6米高,一般为1到2米。花朵乳白色,开花后不久转成深红色然后凋谢,留下绿色小型的蒴果,称为棉铃。锦铃内有棉籽,棉籽上的茸毛从棉籽表皮长出,塞满棉铃内部。棉铃成熟时裂开,露出柔软的纤维。棉花在兵团的农业种植结构调整中占有重要的地位,精量播种是其实施全程机械化急需解决的关键技术之一;目前,棉花播种作业所用的铺膜播种机主要采用机械式精量穴播器。但是这种机械师的穴播器存在易漏气、排种精度低、播种稳定性差、能耗大、伤种率高、高速作业性差、可靠性低的问题,无形之中增加了企业的生产成本,并且工人在操作时存在劳动强度大,效率很低,不适宜棉花的大范围种植,种种弊端决定了机械式穴播器不适宜在我国大范围推广。
技术实现思路
为了克服机械式穴播器在播种种植棉花时的伤种率高、高速作业性差、效率低等问题,本专利技术提供一种气吸式棉花精量穴播器。本专利技术解决其技术问题所采用的技术方案是:该气吸式棉花精量穴播器包括鸭嘴,滚筒进种道,刷种器,分种器,气吸孔,进种口,吸气口,真空腔,种腔,刮籽器,清理毛刷,断气块,其特征在于:作业时,风机使气室内产生负压,种子被吸附在取种盘的吸种孔上;刷种器清除掉多余种子;当种子运动到落种区时,断气块将气孔堵上,负压消失,种子与取种盘吸孔分离,实现1次投种;种子在其重力等综合作用下落入种道,随种道继续滚动,落入鸭嘴内腔,在成穴鸭嘴破膜入土开穴的同时活动鸭嘴被强制压开 ...
