disc ploughAccording to the disc installation can be divided into ordinary and vertical. There is a deflection angle of 10~30 ° between the rotation plane of the common disc plow and the forward direction of the vertical disc plow, which plays the role of bulldozer and enhancing the ability of the disc to enter the soil. The plane of rotation of an ordinary disc plow is not perpendicular to the ground, but is slightly inclined. There is an angle between the rotating plane and the vertical line of the ground, generally about 30 ° to 45 °. An ordinary disc plow with an inclination angle is represented by the acute angle between the horizontal diameter of the disc and the line of the forward direction. It can make the disc easy to cut soil, lift and flip. Disc plows Usually, a scraper is installed behind and above the concave surface of the disc to prevent soil from sticking. The spatula surface also assists in turning.
Verticaldisc ploughThe rotating surface of the disc is perpendicular to the ground, with only a deflection angle and no inclination. The vertical disc plough has a small disc, and there are many discs on a plough (the number of discs on a large vertical disc plough can reach 30 to 40), which is mainly used for shallow tillage and stubble removal. It can also be equipped with seed boxes and fertilizer boxes for joint operations of tillage and fertilization.
Ordinary disc plow and two-way disc plow can turn left and right. The plow beam on which the plow post is mounted can swing horizontally from left to right relative to the plow frame to accommodate the reversal of the disc. The reversing control mechanism may be mechanical or hydraulic. The two-way disc plow allows the soil to turn all the way to one side of the field, leveling the surface after plowing, leaving no gullies.
Drive typedisc ploughIt was developed in some countries in the 1980 s. The tractor power output shaft drives the group of discs to rotate at a speed of about 120 r/min, which has a good effect of turning the soil. Used in wetlands and rice stubble land, can make full use of tractor power.planterThe use also needs attention.
