Description

Adjustable ditching device of seeding and fertilizing machine

Technical Field

The invention relates to a furrow opener, in particular to an adjustable furrow opening device of a seeding and fertilizing machine.

Background

The seed and fertilizer applicator is used in agricultural production, but as is known to those skilled in the art, the contradiction between the advantages and disadvantages of the seed and fertilizer applicator is unacceptable to growers. Such as: the two disk cutting edges of the double-disk furrow opener are intersected at one point (a convergence point m) at the front lower part, the angle of the common convergence point is 55-75 degrees, the furrow opening width, the included angle of the disks, the diameter of the disks and the convergence point angle have a general calculation formula, the disks enter the soil by self weight and additional spring pressure, the disks roll and advance, the soil layer is cut and pushed to two sides to form seed ditches, the seeds are guided into the seed ditches by the seed conveying pipes, and the seeds are covered with soil by returning the soil and the collapsed soil of the ditch walls. The cutting edge is arranged on the periphery of the disc, so that rootstocks and stubbles can be cut off when the disc rolls. Therefore, the furrow opener can also work normally and has stable performance when the soil preparation condition is poor and the soil humidity is high, and is suitable for high-speed operation; the soil layer is not disturbed when ditching, and the seeds can be covered by the wet soil on the lower layer. The seeding and fertilizing machine with the double-disc furrow opener has the advantages that seeding and fertilizing are completed at one time, labor and time are saved, and planting cost is saved. Its shortcoming is, because the structural design of seed manure case and the size of two disc switch wares receive the restriction, seed and fertilizer from two disc furrow openers plant and fall fertile, and seed manure falls into the ditch simultaneously, but when returning soil and not accomplishing, subsequent seed can fall on preceding fertilizer for seed manure is in the same place, leads to the fertilizer to burn kind.
