COMBINED COWLER FOR DIFFERENT SEEDING AND FERTILIZER SEEDING

摘要

The utility model relates to agricultural machinery, in particular to devices for sowing and fertilizing. The combined opener for multi-level sowing of seeds and fertilizing includes a stand (1) with a wedge-shaped chisel, a carbide metal plate (2) is installed in front of the chisel, and the lower part of the stand is made with a ledge (3). A receiver-distributor (4) of the sowing material is rigidly fixed behind the rack, which is a rigid structure in the form of a metal box, inside of which one longitudinal (5) and three transverse mounting plates (6, 7, 12) are rigidly fixed for rigid fixation of the seed guide (8 ) with a seed distributor (9) and a reflective plate (10), as well as a fertilizer duct (11). The fixing plate (12) still performs the function of sealing, it covers the fertilizer with soil, which excludes contact between fertilizers and seeds. Removable cultivator blades (13) are attached to the side walls of the box, and a removable plate (14), which regulates the flow of sowing material, is attached to the rear wall. The use of the coulter with cultivating blades will combine four technological operations in one pass of the sowing unit: loosening the soil, cutting weeds, sowing and introducing a starting dose of mineral fertilizers. Due to the implementation of different depth fertilizing and sowing seeds, the efficiency of fertilizer use is increased, which ensures increased germination and increased crop yields. The coulter design provides the possibility of sowing grain without fertilizing.
