- the area of the working width is sprinkled by the two centrifugal disks by means of the shorter throwing vanes, so that the spreading fans produced by these two short throwing vanes overlap at least approximately completely, while the longer throwing vanes essentially coexist with the area adjoining the working width area Sprinkle the spreading fan generated by the fertilizer particles thrown out by the throwing blades.
- border spreading only the fertilizer particles thrown off only by the longer throwing vane adjacent to the border are to be diverted by means of a border spreading device.
- a border spreading device having guide elements to be arranged on the side of the spreader adjacent to the border, which deflects at least the fertilizer particle stream thrown off by the longer throwing scoop adjacent to the border in such a way that a scatter pattern reaching to the border and having a scattering flank steeply falling to the border can be achieved.
- a scatter pattern with a steeply falling scatter flank can be generated in a simple manner.
- the border spreading device is designed in such a way that the border spreading device deflects the fertilizer particle stream thrown off by the throwing blades in the direction of the field edge boundary in such a way that the fertilizer particles are not thrown beyond the field edge limit and a scatter pattern is formed with the scatter flank falling steeply towards the border.
- the shorter and longer throwing blades of each centrifugal disc have an aspect ratio or a ratio of the discharge edge speed the longer and the shorter throwing blades of about 1: 1, 5 to 1: 1, 7.
- the shorter and the longer throwing blades are arranged on each centrifugal disc in such a way that the two shorter throwing blades sprinkle the working width range with at least approximately double overlap of the spreading fans they produce, and that the longer throwing blades cover the whole Increase the spreading width of the centrifugal fertilizer spreader to twice the working width.
- the throwing blades are designed telescopically, that different working widths can be adjusted by the setting of the telescopic throwing blades.
- An advantageous arrangement of the throwing blades on the centrifugal discs is achieved in that the shorter throwing blade compared to the longer one Throwing blade is arranged lagging by an angle of greater than 180 °, preferably approximately of 210 ° with respect to the direction of rotation of the centrifugal disc.
- the shorter throwing blades with respect to the longer throwing blades and with respect to the direction of rotation of the centrifugal discs are arranged such that the attachment points of the throwing blades enclose an angle of greater than 180 °, preferably approximately 210 °, so that the shorter ones compared to the longer throwing blade is set back against this direction of rotation by this angle or is arranged behind the respective centrifugal disc.
- the centrifugal fertilizer spreader has the frame 1 and the storage container 2, which is divided into the two hopper tips 4 by the roof-shaped central part 3.
- the funnel tips 4 are completed by the metering elements 5, which are adjustable by means of the adjusting elements 6.
- the material in the storage container 2 is supplied in adjustable amounts to the centrifugal disks 7 and 7 'via the metering elements 5.
- the longer throwing blade 8 and the shorter throwing blade 9 are arranged on the centrifugal discs 7.
- the left-hand centrifugal disc 7, as seen in the direction of travel 10, is shown in FIG.
- the right-hand centrifugal disc 7 'seen in the direction of travel 10 is a mirror image of the centrifugal disc 7 shown in FIG.
- the throwing blades 8 and 9 are also designed to be mirror images.
- the centrifugal disks 7 are driven by a motor drive rotating in the direction of the arrow and in the opposite direction of rotation, as the arrows 11 and 12 show.
- the respectively shorter throwing blade 9, 9 ' is arranged to lag behind the respectively longer throwing blade 8, 8' by an angle ⁇ of greater than 180 °, preferably approximately 210 ° in relation to the direction of rotation 11, 12 of the respective centrifugal disc 7, 7 '.
- the respectively shorter throwing blade 9, 9 ' is arranged in relation to the respectively longer throwing blade 8, 8' and in relation to the respective direction of rotation 11, 12 of the respective centrifugal discs 7, 7 'such that the fastening points 8 ", 9" Throwing blades 8, 8 ', 9, 9' enclose an angle ⁇ of greater than 180 °, preferably approximately 210 ° with one another, so that the shorter one compared to the longer throwing blade against the direction of rotation 11, 12 is offset by this angle and arranged behind.
- the material in the form of the spreading fan 13 is thrown off from the shorter throwing blade 9 of the left-hand centrifugal disc 7.
- the material in the form of the spreading fan 14 is thrown off from the shorter throwing blade 9 'of the right-hand centrifugal disc 7' seen in the direction of travel 10.
- the material in the form of the spreading fan 15 is thrown off the longer throwing blade 8 of the left-hand centrifugal disc 7, while the material is thrown off in the form of the spreading fan 16 by the longer throwing blade 8 'of the right-hand centrifugal disc 7'.
- the shorter throwing blades 9 and 9 'of the two centrifugal discs 7 and 7' essentially only sprinkle the area of the working width A, while each longer throwing blades 8 and 8 'essentially cover the working width on their side A adjoining area B with a small overlap zone C of the spreading fans 13, 14, 15 and 16, respectively, which are generated by the long throwing blades 8, 8 'and by the shorter throwing blades 9, 9'.
- the throwing distance W corresponds, as shown in FIG. 3, to twice the working width A.
- the shorter throwing blades 9, 9 'of the two disks 7, 7' sprinkle at least approximately in each case over the entire spreading range of the working width A, since their spreading fans 13 and 14 are at least extend approximately over the entire width of the working width A.
- the shorter throwing blades 9, 9 'and the longer throwing blades 8, 8' of each centrifugal disc 7, 7 ' have an aspect ratio of approximately 1: 1, 5 to 1: 1, 7 to one another. Due to the differences in length from the shorter to the longer Throwing blade and the drive speed of the centrifugal disks 7, 7 'results in a ratio of the discharge edge speeds of the shorter throwing blade 9, 9' to the longer throwing blade 8, 8 'of approximately 1: 1, 5 to 1: 1, 7.
- the shorter throwing blades 9, 9 'and the longer throwing blades 8, 8' are arranged on each centrifugal disc 7, 7 'in such a way that the two shorter throwing blades 9, 9' cover the working width range a of the working width A with at least approximately double overlap of those produced by them Sprinkle spreading fans 13, 14, the longer throwing blades 8, 8 'increasing the entire throwing width of the throwing distance W of the centrifugal fertilizer spreader to twice the working width A, as shown schematically in FIG.
- the spreading fans 13, 15 shown with dashed lines must be in the middle of the border spreading device 17 in the shown with solid lines Spreading fans 13 ', 15' can be changed.
- the border spreading device 17 having the guide elements 19 is arranged and pivoted into the trajectory of the fertilizer grains, so that these guide elements 19 the at least the fertilizer flow which is deflected off the longer, adjacent to the border 18 throwing blade 8 redirects that a scatter pattern reaching to the border 18 and having a scattering flank steeply falling to the border can be reached.
- the throwing distance W of the fertilizer particles thrown off by the throwing blades 8, 8 ', 9, 9' of the centrifugal disks 7, 7 ' is set up to be twice as large as the working width A, this double width only for the long blades 8 , 8 'is set up.
- the short throwing blades 9, 9 'of the two centrifugal discs 7, 7' are set so that the entire working width A is covered twice in the central region of the throwing distance.
- the short throwing blades 9, 9 ' being positioned on the centrifugal disc 7, 7' in such a way that they process or receive two to three times the amount of fertilizer, as do the longer ones Throwing blades 8, 8 '.
- the area of the working width A that is to say from the two centrifugal discs 7, 7 ', is sprinkled, by means of the fertilizer particles thrown off essentially by the shorter throwing blades 9, 9', while the long throwing blades 8, 8 'by the centrifuging of the fertilizer particles Sprinkle each area B adjoining the working width A with an overlap C of the fertilizer particles thrown off by the shorter throwing blades 9, 9 '.
- the shorter and longer throwing blades can be designed telescopically, so that in each case an optimal setting of the spreading work on the desired working width A can be easily achieved.
- the fertilizer flow flung out beyond the working width A, which is essentially arranged by the longer throwing blade 8 of the centrifugal disc 7 adjacent to the boundary 18, is deflected, it having proven advantageous, even if that of the shorter throwing blade 9, which is arranged on the centrifugal disc 7 adjacent to the boundary 18, is also deflected in the outer region by the guide elements 19 of the boundary spreading device 17 in order to achieve a uniform fertilizer distribution.
- the fertilizer flow supplied to the border 18 of the centrifugal disc 7 must be reduced by the appropriate setting of the metering element 5.
- Centrifugal discs 7 or the throwing blades can be adjusted by a corresponding length adjustment.
- the respective centrifugal disc 7 with correspondingly long throwing blades can be exchanged for one another if corresponding centrifugal discs 7 with correspondingly long throwing blades are available for the desired working width A or working width range.
