摘要

The invention relates to an agricultural mounted trailer for distribution and special introduction of liquid, nitrogen and phosphate fertilizers, in particular manure, fermentation residues, residual fertilizer (from various sectors of industry) and sewage sludge in row crops of agriculture and horticulture, especially in the row crop corn. It is a device that can either be attached to tractor-guided slurry tankers with 1-4-axis, self-propelled slurry tankers / Ausbringfahrzeuge with its own storage tank, or directly to tractors and then via a so-called slurry manure system attacks or can be operated. Advantageous points of the invention are that this device is equipped so that it is both the 1 mtr. According to the German Fertilizer Ordinance (fertilizer with essential nutrient contents in the dry matter of more than 1.5 per cent nitrogen, total N or 0.5 per cent of phosphate P2O5 may only be at least 1 mtr to the apex of a body of water , be applied with exact fertilizer devices or devices with Grenzdüngeeinrichtung, otherwise a distance of at least 3 mtr. must be observed) as well as full fertilization of the first, outer row of a row crop (especially corn row) of a field, within the field between the 1st and 2nd It is also possible to inject the liquid manure on sloping sites in row crops, and also in large working widths that overlap across the sawn width, for example with sawing widths of 4-24 rows and injector working widths of 5-18 rows, without fluctuating intermediate distances of the Connecting rows the subsequent rows (especially at 75 cm Reihenabs tand) or to damage the roots (especially in maize up to the 8-10 leaf stage), provided that the towing vehicle is exactly to control, this also means that the machine can then work without any GPS system, provided that the row widths are at least 60 cm. Furthermore, it is advantageous that in the device a very accurate left-right application is achieved in side slopes, with a Mindestverteilqualität at 10% slope on mountain and valley side with a coefficient of variation less than or equal to 5% at a minimum distance of 150 mtr. and at least 20 m3 / ha at 10 km / h driving speed. Furthermore, an important point that the frame wings right and left have a separate ground adaptation, which allows a safe incorporation on relatively uneven fields, is also advantageous what is especially important for large working widths is additionally a collision. Furthermore, the device advantageously has a quick-change system of the sharpening tools so that the user can react very quickly to different soil and weather conditions during use, all the more important there with screwed working tools with nitrogen-containing fertilizers, since screw connections on the coulters both use very quickly corrode (screws made of stainless steel or galvanized screws in the design and hardness are usually not offered), advantage no long downtime at share change, this is important because a slurry chain from application and Zubringfahrzeugen, per minute life up to 8 € uro in costs caused.
