Abstract

1. The coulter for layer-by-layer sowing of seeds and fertilizing, including a lancet paw attached to the stand, fertilizer guide, seed guide, ramp, dihedral wedge, characterized in that the lower part of the fertilizer guide is recessed with the possibility of fertilizing below the seed sowing layer, and a dihedral wedge made in the form of a knife with a bevel to the lower point of the guide. 2. The opener according to claim 1, characterized in that the pitched plate is installed with the possibility of creating an even compacted bed for even distribution of seeds over the area and depth.

Description

The utility model relates to agricultural engineering and can be used in seeders for sowing grain crops and fertilizing.

Known combined working body for sowing seeds of different depths, (utility model patent No. 116307 of the Russian Federation, АСС 7/00 "Combined working body. Publish. 05.27.2012) [1], which includes a lancet paw, chisel, a guide for seeds and fertilizers, spreader. The device allows you to lay seeds and fertilizers at different sowing depths. The working body in the form of a lancet paw is equipped with a chisel. The fertilizer guide is located in the middle part of the working body and has a greater depth than the seed guides. The disadvantage of this design is that the opener equipped with a chisel only works with a well-aligned field. The tips of the bit wear out quickly, increasing the traction resistance of the coulter.

Another prototype for layer-by-layer sowing of seeds and fertilizing is a combined tillage-fertilizer-sowing coulter (patent 2366145RF, A01C 7/20. Publ. 10.09.2009) [2].

During operation of the combined opener, the lancet paw cuts the formation, compacts the wet layer and forms a mulching layer with the working surface. Trihedral wedges form a fertilizer location region below the level of the paw stroke depth of 3 to 4 cm. Mineral fertilizers enter the vertical channel and are sent to the hollow region along the horizontal channel. Seeds enter the stabilizer and through the vas deferens into the diffuser, which has the shape of a semi-cone, the seeds are laid on the surface of the densified layer, dumping headers close up the trace from the rack and form a mulching even layer. The disadvantage of this design is that fertilizers are embedded in the lower soil layers with a wedge after sowing, which violates the uniformity of sowing seeds in depth. This coulter design is difficult to implement.

The closest in technical performance and the achieved result is a coulter for seed placement at different depths, (RF patent No. 2412579 class A01C, published 02.27.2011. Bull. No. 6) [3]. This coulter includes a runner, cheeks located on both sides of the runner, with side bumps made with a bevel towards the central bump and located at different heights. The opener for heterogeneous termination works as follows. Seeds from the sowing apparatus fall into the corresponding vas deferens and further along the guides are laid alternately behind the oral pliers. The disadvantage is that conditions are created for the germination of not all seeds, but 1/3 of them, which leads to a large consumption of expensive seeds and there is a dependence on weather conditions.

The purpose of the proposed utility model is to eliminate a number of drawbacks; this is to provide the optimum seed and fertilizer planting depth to provide plants with nutrients during germination. Fertilizing below the seeds avoids a burn of the root system of plants and favorably affects the growth and development of seeds, which makes it possible to increase productivity [4]. This goal is achieved by the fact that the fertilizer introduces fertilizers below the position of the seeds and its lower end is bent so that there is no clogging with soil. Its lower part deepens and reduces the vertical component of traction resistance due to the installation of a two-sided wedge in the form of a knife with a bevel to the lower point of the guide.

The invention is illustrated by drawings.

In FIG. 1 schematically shows the opener, its main view, in FIG. 2 in section, the process of sowing seeds, in FIG. 3 rear view. The paw opener contains a lancet paw 1 attached to the stand 2, the guide 3, the seed guide 4, the knife guide 5, the ramp 6. The knife guide, which has the shape of a wedge, cuts the soil layer, forms a bed for fertilizing located below the seed level. In the sublap space, the fertilizer guide is installed so that fertilizers can be placed below the seed sowing layer. The device operates as follows, lancet paw 1 cuts the formation, loosens the soil and forms the soil layer, the seeds of grain crops enter the seed guide 4 and are laid on the surface of the compacted layer, which is formed by the ramp 6. Fertilizers enter the fertilizer 3. A useful model improves germination seeds due to fertilizing below the layer of sowing seeds and helps to increase productivity. Since during the development of the root system, plants will receive nutrients from the lower layers of the soil
