The invention discloses a high-speed mechanical ejection type seed direct sowing device which comprises a rack, and a seed storage box, a seed discharging mechanism and a seed launching mechanism which are arranged on the rack, a discharging hole of the seed storage box is communicated with a feeding hole of the seed discharging mechanism; the seed discharging mechanism is used for conveying the received seeds to an emitter region of the seed discharging mechanism one by one according to a preset time interval; the seed launching mechanism comprises a push rod and an intermittent gear; the push rod is vertically arranged to be of a structure which can move up and down and has a self-resetting function, a vertically-arranged rack is arranged on the push rod, and the lower end of the push rod penetrates through a shell of the launching area and extends to a launching opening of the launching area; a tooth area and a toothless area are alternately arranged on the peripheral wall of the intermittent gear, and rotation of the intermittent gear is used for alternately switching the meshing state of the tooth area and the rack and the meshing releasing state of the toothless area and the rack so as to control the push rod to alternately move up and down; after the scheme is adopted, the problem that long-term continuous and efficient driving of seeds cannot be realized in the prior art can be solved.
本发明公开了一种高速机械弹射式种子直播装置,包括机架、以及设于机架上的种子存储箱、排种机构和种子发射机构;种子存储箱的出料口与排种机构的进料口接通;排种机构用于将接收的种子按预设时间间隔逐粒送至其自身的发射区;种子发射机构包括推杆和间歇齿轮;推杆竖向布置为可上下移动、且具备自复位功能的结构,推杆上设有竖向布置的齿条,推杆的下端部穿过发射区的外壳、并延伸至发射区的发射口处;间歇齿轮的周壁交替设置有齿牙区和无齿区,间歇齿轮的转动用于交替切换齿牙区与齿条的啮合、以及无齿区与齿条解除啮合的状态,以控制推杆交替上下移动;采用此方案后,将可解决现有技术无法实现种子长期连续高效打入的问题。
