1986年,我们对48行播种机进行了大豆垄体深松播种同位分层施肥的改装,经过使用,效果良好,现将改装方法介绍如下。 48行播种机后行开沟器位置不动,将前行开沟器的升降杆加长并把开沟器的总成换成靴型开沟器(见图一)。靴型开沟器由中耕机的杆齿后面加开沟分层施肥筒组成(见图二)。安装时,必须把靴型开沟器与后行开沟器调整同位,并按播种深度要求调整杆齿的高度,以达农业技术要求。
In 1986, we carried out a 48-row sowing machine sow ridge deep pine sowing the same stratification fertilization modification, after use, the effect is good, now the modification methods are as follows. After 48 rows of planters, the opener position is not changed. The lifting rod of the opener is lengthened and the opener assembly is changed to a shoe opener (see Figure 1). Boot-type opener from the tillage machine behind the tooth plus ditch layered fertilizer composition (see Figure 2). During installation, the shoe opener and the rear opener must be adjusted in the same position, and the height of the gear teeth should be adjusted according to the sowing depth to meet the agricultural technical requirements.
