EFFECT: provision of compacting the soil in the area of the seed location, tillage depth adjustment, and enhanced functional capabilities.
The invention relates to the field of agricultural engineering, namely to tillage implements with passive working bodies, and can be used with agriculture for early spring harrowing for seedbed preparation prior to sowing, for subsurface reconsolidation of crops with additional simultaneous shredding and fluffing of the surface layer of the soil and its uniform distribution over the surface of cultivated fields, for the destruction of soil crusts in the germination of crops and the prevention of drought, the cracked vapors and fields after harvesting, and for post-harvest tillage fluffing with simultaneous and uniform distribution of loosened soil layer on the surface of the treated field with the creation of conditions for the autumn accumulation of moisture in the soil and triggering germination of weeds and volunteer.
Know tillage tool - wide rink Kolkata-gear, comprising a frame with a trailer supported at the rear on two pneumocytes, which can be translated hydraulic cylinders from a horizontal working position into a vertical transport position revolving frame mounted with wings, on the wings staggered overlapping edge is fixed packer section, the wings are installed on the frame podernos rotatable cylinders forward to fixing them to the frame of the trailer in a transport position, all the packer sections consist of a framework, in which bearing units fixed battery, consisting of a shaft, wheels with a rough surface and Zubov disks (rink ringed-notched Mace To 3-12,4, manual, LLC "TC Engineering, Voronezh).
The disadvantages of the above tools is that the packer section rolled down an uneven surface, though unevenly, but the entire surface of the cultivated fields to the formation in the soil capillary duty cycle, and the toothed discs carry out some of its loosening. Due to its small width of the toothed disks and their height can be assumed that the entire surface of cultivated fields and rolled all the seeds are in optimal germination conditions, but in this case, the capillary porosity in rolled the soil will not only bring the soil moisture to the surface of seeds, but will output it to the surface of the field, where the daytime on the surface of the soil, the air and the top layer of soil is heated to 50-70°C. This leads to the rapid evaporation of this soil moisture and lifting another one. As the highly heated air (temperature of 50-70°C) rushes up over such field generated sustained updrafts that can capture the pairs of soil moisture and carries it into the atmosphere, thus we can say that we artificially formed�Ali solar pump for draining moisture from the soil, moreover, if sown field sufficiently large, then the formed by updrafts prevent the entry above this field rain clouds, thus excluding the possibility of natural irrigation of the crops. And while the seedlings sown plants will not close its greenery entire surface of the field, rainfall on them is almost impossible, except if such fields rolled formed soil crust and soil moisture is not enough and no rain, we may form in the soil cracks that will lead to its final drying and total loss of sown plants.
Thus, ring-s-tine wheels provide almost complete consolidation of the surface of cultivated fields, creating optimal conditions for germination and the germination of seeds, but they do not provide safety in the soil soil moisture, but rather create the conditions for mass pulling from the soil and evaporation.
If the soil moisture is not enough, we even got a good uniform germination in the following may just wither for lack of moisture and lack of rain. To this risk is to minimize, in addition to a full rolling surface cultivated fields to ensure his protection from the mass evaporation from the soil moisture and, if necessary, to ensure the destruction of soil cork� and to create conditions for further accumulation of moisture in the soil from the atmosphere.
The closest to the proposed invention is a wide-tillage machine, adopted for the prototype (patent for invention RU №2511945), containing frame with drawbar hitch, rear part based on pneumatic wheels, medium swivel beam clamp-hydraulic cylinders to the frame, which by means of hinges in the form of frogs swivel-mounted side-impact bars with workers and transport wheels, the U-shaped leashes, stretch marks, consisting of two parts, the front - rear short and long, with fingers, springs, ramps and detents on the rotary bars mounted fixedly, stretch marks are the latches in the form of corners with cutouts interacting with the grooves on the fingers fixedly mounted on brackets mounted on short pieces of stretch marks, and their long rear part on the side of the mount with the U-shaped leads are equipped with horizontal axes, removable rack pair or replacement of a single long rack with Zubov harrows, zigzag, fixed anchor chains, adjustable length.
The disadvantages of the above-mentioned wide tilling unit is that the connection sections tillage working bodies with longitudinal bars (pillars) by means of anchor chains does not allow the slave process�you transfer some of the weight tilling unit, and the working bodies Zubov harrows zigzag provide only loosening with simultaneous alignment of the surface of the treated field, whereas when sown simultaneously with the loosening and leveling of the surface layer of soil is necessary and subsurface consolidation of the soil in the area of seeds, which increases the contact of seeds with soil and provides a process of capillary supply of moisture to the seeds from deeper soil layers. This will allow to obtain uniform and rapid germination. The disadvantage of wide tilling unit also is the inability to control the depth of tillage and limited its scope.
The aim of the invention is to provide a tilling unit working bodies, which in addition to loosening and leveling the surface of the treated field during seeding would ensure and subsurface consolidation of the soil in the area of finding seeds that will provide uniform and shoots much faster, as well as an introduction to the Assembly design of mechanisms to adjust the depth of tillage and enhanced functionality of the unit by the use of replaceable elements.
The goal of the invention is achieved in that the proposed wide-swath multi-pochvoobrabotki�panel unit, contents frame with drawbar hitch, rear part resting on two pneumatic wheels, medium swivel bar installed in the rear of the frame, rotation of which is effected by hydraulic cylinders, the ends of the secondary rotary bar mounted hinges in the form of frogs, which are mounted on the side pivot bars with workers and transport wheels, the middle and lateral pivoting parallel bars mounted sections tillage working bodies, the lateral ends of the turning bars is connected to the front part of the frame braces, consisting of two parts - front short with traps and snaps and the back is long, one ends of which are connected movably with the U-shaped leads, mounted movably on the frame, the other ends are mounted on the ends of the side rotary bars, rear - long piece of stretch marks, next to the vertical axis of the connection of these parts stretch with the U-shaped leads are horizontal axis. In this section tillage bodies made interchangeable and may represent a section of the helical rollers, or partition disks-hoes, or partition disks cultivator are installed with overlapping edge adjacent sections and are mounted via parallelogram mechanisms by means of longitudinal beams and pairs of coupling clamps in such a way�m, that section, installed at the edges of the side rotary bars, located behind them in the direction of the unit and block the front wheels, while all sections are installed at an angle α, where α is the angle between the direction of movement of the unit and perpendicular to the axes of these sections, a pair of fixed longitudinal bars and a pair of parallelogram mechanisms, of which the lower pair of straps in the rear part is equipped with a system of holes through which the fingers of the clamps is mounted the depth of the soil, and in their front top has a restrictive grooves into which are fitted the constraint axis, fixed longitudinal beams and the front lower parts are brackets with holes, through which the fingers of the springs, the second end attached to the adjustment screws mounted in brackets fixed to the longitudinal beams, and a pair of movable longitudinal bars, one of which has one hole for mounting the replaceable sections, and the second has a system of holes that allow you to change the angle α of 10° to 35° with an interval of 3°-5°.
These differences are essential, as introduction to the design of wide-span multi-function tillage units spring mechanisms, the parallelogram mechanismus system of apertures and fingers-clamps, and the possibility of changing the angle α of operating tools allow to make processing of the soil within the width of the unit without blemishes and implement a stepped adjustment of the depth of processing. The use of helical rollers provides subsurface consolidation of the soil in the area of finding in the soil seed that, on the one hand, will create optimal conditions for seed germination, and on the other, forms on the surface of cultivated fields loose surface layer of soil, which will dramatically reduce the evaporation of moisture from the soil.
The change in the angle α of operating tools allows in the process of tillage or cultivation significantly change the intensity of the impact of replaceable working bodies in the treated soil and plants, so, for example: when you increase the angle α installation disc cultivator of short conception occurs an increase in the depth of the soil, by increasing the angle α installation disks-hoes increases the intensity of their impact on the soil and on plants, i.e. increased loosening the soil and increasing the number of damaged plants. When you increase the angle α from 0° to 12°-13° in helical rollers increases the area of subsurface soil tamping to 100% and with further increase of angle α, the density increases rolling.
The ability to install in the unit instead of the replaceable helical sections �Menno sections with wheels-hoes allows wide-tillage machine to use for the destruction of soil crust in much grown crops without significant damage to the plants in these crops. This can dramatically reduce the evaporation of moisture from the soil, and create conditions for accumulation of moisture in the soil from the atmosphere (dry watering). Replacement screw sections on the disc the disc will allow you to use the unit vapors to be cracked, peeling plowing, soil preparation for sowing, etc. That is dramatically increases the functionality of the unit and the length of time of its use during the year.
