    10152025302the disadvantages of the prior art and which further develops the latteradvantageously. Preferably a better seed output should be achieved,which allows a precise laying of the grains exactly on the desiredlocation regardless of varying influences.
    This problem is solved, according to the invention, with a seed drill according to claimPreferred embodiments of the invention are the subject matter of the dependentsthe requirements.
    It is therefore proposed to change the output direction and in particularthe discharge angle of the seed from the sowing means, in order to be able to adaptthe deposition of the seed to various influencing parameters.
    The discharge direction of the seed grains from the sowing means is no longerfixed, but can be adapted to different conditions. The outlet pipesof the sowing means according to the invention are angularly adjustable so as toachieve different output directions. The outlet pipes can be set in differentinclination angles and positions, respectively, depending on the circumstances, tobe able to influence the closure pattern in the desired way. In principle, this can be differentAngle adjustability is provided, for example, when sowing slopesbe advantageous to be able to set the outlet pipes at different angles of inclinationdiagonally to the direction of movement. In particular, however, are the outlet pipesadjustable in a vertical plane parallel to the direction of movement, whereby inin particular, it can be ensured that the outlet lines are pivotally mounted arounda horizontal transverse axis, which extends transversely to the direction of movement.
    Through an adjustability in a vertical plane parallel tothe direction of movement can in particular affect depending on the driving speedcompensated.
    In the further development of the invention, there is preferably an automaticcontrol of the angular position of the outlet pipes, and thus of the seedoutlet direction, preferably a change of the outlet linesangular position can also be done while driving and / or sowing, so that with shortnotice and current may react to changed impact. It arrangedthe control device for controlling the angular position of the outlet lines can in this casein principle take into account different operating parameters of the seed drill and / or differentseed parameters or even field processing parameters, wherein10152025303preferably also drifts your operating and / or seed parameters can be taken into accountat the same time.
    In particular, the angular position of the outlet pipes can be varied dependingat the driving speed of the seed drill, preferably corresponding control meansautomatically the angular position of the outlet lines varies in a vertical planeparallel to the direction of movement, for example by turning around onehorizontal transverse axis, when the driving speed of the seed drill changes. The control means canin this case preferably comprising a recording device for recordingdriving speed and be connected thereto, and control an actuator forchange in the angular position of the outlet lines depending on itregistered driving speed.
    The governing body can thus in principle realize different dependencies betweentravel speed and the angular position of the outlet lines, the steeringis preferably designed so that the outlet pipes are inclined more flat withincreasing driving speed, more specifically towards the direction of travel, so that at leasta certain compensation against the driving speed is achieved. By tiltingthe sowing pipes and the outlet pipes obliquely to the rear receive the dropoutsthe seed grains a velocity component in the horizontal direction towardsthe driving speed, so that the seeds fall to the ground with an overall lowerrelative velocity in the horizontal direction. This allows the seed grains to tendto roll on and off on the ground is reduced. At slowerdriving, the sowing tubes are set more vertically, as a lower driving speed shouldcompensated in this case. If, on the other hand, you drive faster, you will be tiltedthe sowing tubes more backwards, ie. set less vertically and flatter, respectively, tocompensate for a higher travel speed component.
    In the case of advantageous further development of the invention, this can be donethe angular position of the outlet pipes is varied depending on the speed of someans that the seed falls mainly vertically to the ground and / orthe driving speed is mainly completely compensated by the seedfalling, ie. the seed grains have no relative velocity in horizontaldirection towards the earth. This can lead to an unintentional rolling away andthus an undesirable spread of the closure pattern to a large extenteliminated. The seed grains are laid considerably more precisely on the desired ones10152025304the places. In particular, a roll-out from the tracks and the desired is avoidedthe distance between two successively laid grains is followed exactly.
    The angular position of the sowing pipes and the outlet pipes, respectively, can iprinciple follow a range from 0 to 90 °, preferably a setting range of75 ° is enough. In particular, the angular position is set between approximately 20 ° andabout 75 ° to the vertical, depending on the driving speed, wherebyadvantageously the sowing tubes are inclined obliquely backwards and downwards.
    In the further development of the invention, the control device can also takeconsideration of additional operating parameters and / or seed parameters forchange in the angular position of the outlet lines. For example, one canangle of inclination of the fields to be sown and / or an inclination ofthe sewing machine opposite the horizontal line is taken into account. Alternatively or additionally canthe angular position of the outlet pipes also changes depending onthe height of the sowing tubes above the ground, which for example can vary through differentsettings of the track roller.
    In particular, the control device can also take into account the grain weight and / orthe grain size of the seed, when setting the outlet linesangular position. This can in particular be implemented in such a way as to influencedue to the driving speed and wind speed are compensated. For examplethere may be very light grains and / or very large grains with largesurface at comparatively low weight is slowed down more by the headwind when falling fromsowing means, while on the other hand very heavy grains are less affected bythe air resistance and thus the wind speed when falling. Preferably cantherefore a flatter inclination angle is set for smaller and / or heavier grains thanfor larger and / or lighter grains, which are slowed down more by the wind.
    Preferably, such consideration is combined with seed parameterswith the aforementioned consideration of driving speed, to ifpossible to achieve a closure of the seed grains without relative speed inhorizontal direction.
    Taking into account the mentioned operating parameters and / orthe seed parameters can be implemented in different ways purely control technically, iin particular in such a way that the operating parameter in question is registered10152025305and, depending on the registered size, of the outlet linesangular positions are determined according to a certain context.
    Alternatively, or in addition, the control device may also comprise oneregulator which regulates the angular position of the outlet lines depending onthe relative velocity of the grain compared to the soil and / or depending onthe angle of impact of the ground. For example, one can, by appropriateregistration means, record the relative velocity of the falling seedrelative to the soil and / or the angle of impact of the seed towards the soil. Through acomparison of setpoint and actual value can the sewers respectivelythe angular position of the outlet pipes is regulated by a corresponding value, sothat the seed can fall to the ground if possible without relative speed and / orvertically, in the desired manner.
    The invention is explained in more detail below with reference to a preferred oneembodiment and associated figures. The figures show:Figure 1: a schematic side view of a row seed drill according to a preferred oneembodiment according to the invention,figure 2: a schematic plan view of the row sewing machine in figure 1,figure 3: a schematic representation of a sowing pipe and itsangularity as well as the resulting kinematic quantities at onethe falling motion of the grain,Figure 4: a diagram-like representation of the relationship betweentravel speed and angle of inclination of the sowing tube.
    The sewing machine 1 shown in the figures is designed in the form of aseed drill and comprises a seed hopper 2, which sits on amachine frame 3, which can be attached to a tractor via a drawbar 4.
    Under the seed hopper 2 a soil cultivating device 5 is in shapeof a harrow arranged, which is designed as a transverse disc harrow in itshowed the embodiment. The soil cultivating device 5 is attached tomachine frame 3.
    The post-soil cultivating device 7 has a barrier roller 6 which packsthe pre-worked soil and makes sowing tracks in it.
    Behind the locking roller 6, seen in the direction of travel, there are a number of sewing means7, which sowing means are arranged at a distance from each other in one10152025306row across the direction of travel. Preferably, the sowing means 7outlet pipes 8 in the form of sowing pipes 9, the mouth of which is arranged abovethe contact surface of the track roller 8 and thus above the ground. Said sowing tubes 9are then connected to the seed magazine 2 in a manner known per se, in order thatspread the seed. The seed then falls from the sowing tubes 9 into those ofthe track roller 8 made the sowing tracks and remain lying on the ground. Mentionedsowing pipes 9 are in this case preferably arranged in line with those of the sowing groovesgutters.
    Instead of sowing tubes, the sowing means 7 may also comprise differentdesigned outlet pipes 8, for example gutter-shaped structures, whichdetermines the outlet direction of the grains. Preferably, however, are mentionedsowing pipes 9 are arranged, these being arranged directly in the one shownembodiment. Alternatively, however, cup-shaped, curved tubes can also be usedarranged.
    After said sowing means 7 there is a post-packing roller 10, which canbe designed as a pack wheel roller. Furthermore, in the direction of travel, ascraper 11 must be arranged after the post-packing roller 10.
    Said sowing tubes 9 are adjustable in their angular directions, onadvantageous way. In particular, said sowing tubes 9, as shown in Fig. 3,pivotally mounted about a horizontal pivot axis 13 which extendsacross the direction of travel 12, so that the seed tubes 9 can be inclined differently in onevertical plane running parallel to the direction of movement 12.
    For changing the angular position of the sowing tubes 9, preferably oneactuator 14 may be arranged, for example in the form of a pressure medium cylinder,which is preferably controlled by a control device 15, which automatically controlsthe inclination of the sowing tubes depending on the driving speed and the grain weight.
    The control device 15 for this purpose preferably comprises registration means16 for registration of the driving speed 17, cf. figure 3. Depending onthe driving speed 17 thus changes the inclination of the control device 15 of the sowing tubes 9such that the driving speed 17 is mainly compensated, i.e. the seed tubes9 is adjusted so that the horizontal component ofthe discharge velocity 18, at which the grains are discharged from the seed tubes 9,107in size approximately corresponds to the driving speed 17, which, however, is opposite,cf. figure 3.
    As Figure 4 shows, the control device 15 varies with the sowing tubes9 inclination angle cp depending on the registered travel speed VDrive. The anglecp is in this case the angle of inclination of the respective sowing tube 9The iodine line. If the seed drill 1 runs faster, the sowing tube 9 is tipped more backwardstowards the iodine line, so that the higher travel speed 17 can be compensatedthrough a larger horizontal component of the output speed 18. Asresults, the grain hits the soil mainly vertically, ie. with a relativevelocity, between soil and grains in the horizontal direction, as mainlyamounts to 0.
