1大田播种机(1)垄距调整。用米尺测量单体上两铧尖之间的水平距离,一般在40～60 cm,合适后旋紧U形卡子,注意螺母下一定要加弹簧垫圈。(2)耕深调整。用米尺测量单体上的地轮轮圈离地最低点,与开沟器铧尖之间的垂直距离,一般为3～8 cm,合适后,用顶丝固定住开沟器总成,并旋紧锁紧螺母。(3)排种量的调整。以窝眼式为例,松开刮种舌螺母,向上调整刮种舌,使刮种舌与窝眼轮之间的间隙变大,排种量变大,反之,排种量变小。
1 Daejeon seeder (1) Ridge adjustment. Measured with a meter ruler on both sides of the tip between the horizontal distance, usually 40 ~ 60 cm, tighten U-shaped clip appropriate, pay attention to the nut must be added under the spring washer. (2) tillage adjustment. With a single meter on the meter to measure the lowest point of the ground wheel rim, and the opener tip between the vertical distance, usually 3 ~ 8 cm, appropriate, with a top wire to hold the opener assembly, Tighten the lock nut. (3) the adjustment of seeded species. Take the socket type as an example, release the scraping seed tongue and adjust the scraping tongue upward to make the gap between the scraping type tongue and the socket wheel larger and the seeding rate larger. On the contrary, the seed volume will become smaller.
