    • A seeding machine comprises: an air compressor for generating a positive air pressure; a soil hardness sensor for measuring soil hardness so as to produce a control signal to adjust the positive air pressure generated by the compressor; an air pressure adjuster for adjusting the positive air pressure generated by the air compressor in accordance with the control signal produced by the soil hardness sensor; a negative air pressure generator for generating a negative air pressure by making use of air under the positive air pressure; a change-over valve for effecting a change-over operation between the positive air pressure and the negative air pressure, so as to selectively supply the positive air pressure or the negative air pressure; a seed adsorber for catching a seed by virtue of the negative air pressure; a first air cylinder adapted to extend or contract by the positive air pressure, to cause a certain reciprocating movement of the seed adsorber; a second air cylinder adapted to extend or contract by the positive air pressure, to cause a reciprocating movement of the seed adsorber between a seed catching position and a seed ejecting position.
    • 播种机包括:空气压缩机,用于产生正气压; 用于测量土壤硬度的土壤硬度传感器,以产生控制信号,以调节由压缩机产生的正气压; 空气压力调节器,用于根据由土壤硬度传感器产生的控制信号调节由空气压缩机产生的正空气压力; 负气压发生器,用于通过在正气压下利用空气产生负气压; 用于实现正空气压力和负气压之间的转换操作的换向阀,以便选择性地供应正气压或负气压; 用于通过负空气压力捕获种子的种子吸附器; 适于通过正气压延伸或收缩的第一气缸,以引起种子吸附器的一定的往复运动; 适于通过正空气压力延伸或收缩的第二气缸,以使种子吸附器在种子捕捉位置和种子喷射位置之间往复运动。
