The invention relates to agricultural machinery, in particular to the direct application of solid mineral fertilizers, and can be used in planters and cultivators-fertilizers for soil fertilization.Known devices for local subsurface fertilizer:
device local subsurface fertilizer , comprising a rack fixed on her opener with anterior segmental cutting edge with cutouts, TakeProfit mounted on the rear wall of the vomer;
the working body for soil bulk materials , containing segmental work is th stand;
known fertilizer Coulter , comprising a hollow rack round cross-section with sloping placed at its output window diffuser, divided fan-shaped radiating fins on the gutter.a device for the local soil fertilization , containing segmental Shoe with an obtuse angle of entry into the soil and slope angle in the vertical plane, the front part of which is made curved, and TakeProfit in the form of a conjugate with each other segments of arcs of logarithmic spirals into one another.All of these devices, designed for subsurface band application of fertilizers, do not have additional devices for fixing the tape fertilizers in a vertical position, the lack of which may result in shattering of the greater part of the fertilizer in the bottom part of the slit formed; devices for regulating the density of distribution of fertilizers, which allow you to change the amount of fertilizer on the height of the vertical slit.A device for local subsurface fertilizer  , consisting of uprights secured thereto segmental working body and tomprof which ensures not vertical, and the inclined arrangement of the tape fertilizer.The purpose of the invention is the provision of opportunities for vertical banded make major dose of solid mineral fertilizers with the regulation of the concentration of the fat on the height of the slit.Design and operation principle of the proposed opener for vertical banded application of mineral fertilizers will be clear from the following description and the accompanying drawings.In Fig. 1 shows the proposed opener; Fig. 2 - B shows the view in Fig. 1; Fig. 3 is a view of A in Fig. 1; Fig. 4 - remote element I in Fig. 1; Fig. 5 - B in Fig. 1.The opener for vertical banded make major dose of solid mineral fertilizers contains a rack guided paw 1, the bottom of which is fixed saleabration 2, from the rear side of the rack 1 has a box-shaped TakeProfit 3, in which the lower part has a slanting cut at the height of meliorates 2, and one cheek of toolprovider in the lower part has a cutout in the form of a trapezoid, the smaller base of which is parallel to the slanted cut and facing in the direction of movement.At the bottom of TakeProfit 3 attached to the end of meliorates 2. Inside toolprovider 3, over an oblique cut at the front and rear e is about a horizontal axis 5 by means of arms 6, moreover, the working edges of the flaps are made curved. Inside toolprovider, cheek against the cutout in the form of fixed-line Ripper plate is triangular in shape, working edges are curved, and the plate is fixed at an acute angle to the direction of movement, and their width greater than the width of toolprovider.The application of mineral fertilizers with a vertical position of the tape is as follows. When moving the unit and the depth of the rack with guided paw 1 saleabration 2 forms a vertical slot, in which toolprovider 3 received mineral fertilizers. Ripper plate 7 located inside toolprovider 3 cheek against neckline in a-line, loose one wall formed by the slit, due to the inclined their location to the direction of movement send the soil to meet the fertilizer coming on toolprovider 3, and thus facilitate better mixing them with soil and fixation in the cracks along the entire height. Regulation of the density distribution of fertilizers at the height of the vertical slit exercise valves 4 by changing its angle relative to the front and rear walls of toolprovider 3. A more uniform distribution is="ptx2">Turn this will improve technical and economic efficiency of the process of fertilization, namely, to reduce consumption and improve the quality of placing them in the root zone of plants that will have a positive impact on the ecological state of soils.Sources of information
