Description

"Fertilizer distributor for agricultural use".

  The present invention relates to a

  fertilizer plant comprising a centrifugal mechanism

  rotated to distribute fertilizer or

  comprising a feed hopper with dosing elements for at least one spreading disc and preferably two spreading discs juxtaposed transversely to the direction of movement, each spreading disc being equipped with at least one and preferably two projection members, the projection members being able to pivot angularly in the plane of the disks and to lock in different positions on each disk, the angularly pivoting projection members cooperating with adjustment markers or

  locking means for adjusting the

  precise angular setting, for example in the form of adjustment scales cooperating with the projection members. Such fertilizer distributor shaped centrifugal distributor is already known according to DE-OS

  29 08 949. The projection devices equipping the

  This centrifugal fertilizer spreader is designed so that the vertical ejection angle at which the particles are projected

  fertilizer can be modified and for the distribution of

  fertilizer can also be used for so-called cover spreading when plants are

  are already developed. In addition, the angle of adjustment

  Ricefront of the projection organs is adjustable.

  To give the farmer precise information on the respective correct adjustment of the vertical ejection angle and the horizontal angle of adjustment of the projection members, - on each pivoting outer part of the projection members, there is an index and on each inner part one has a ladder; another ladder is provided on the spreading disc. These scales include, for example,

  markers in color, in letters or in-ch: ffres.

  Like the respective scales of the disks

  spreading are more or less swept by the parties

  fertilizers, these scales are subject to certain

  wear caused by the friction of the particles of

  grease or tend to become clogged with

  greasy, which makes these different markers invisible and no longer allows to identify the various landmarks and thus allow a simple adjustment of angles. The present invention thus aims to

  provide adjustment marks cooperating with the or-

  projection ganes on the spraying discs

  to be insensitive to chafing or

  fouling by the particles of fertilizer

these invisible landmarks.

  This problem is solved according to the invention in that the adjustment marks which cooperate with the respective projection members are provided on the spreading discs in an area which arrives only slightly

  or not at all in contact with the particles of

  to be sprayed by the protection organs.

  Thanks to these characteristics, the adjustment marks cooperating with the projection members are protected from the particles of fertilizer to be ejected so as to

  practically not be directly exposed to

  fertilizers; this prevents the friction wear of the adjustment marks by the fertilizer particles or the sticking or fouling of these marks until they are invisible; we can thus adjust

  This allows setting marks even after several years of use of the fertilizer spreader, to recognize these benchmarks

  projections of the spraying discs

  provided by the distribution boards.

  According to a preferred embodiment of the invention, the adjustment marks are provided in an area which, seen in the direction of rotation of the disks.

  spreading is behind and / or below the

  respective projection jaws, the adjustment marks cooperating with an index lying at the level of the back

projection organs.

  According to another embodiment, the adjustment markers are provided at the pivot pin of the projection members and in that the edge of the projection member which is closest to the axis of rotation of the disc. spreading

is in the form of index.

  According to a particular embodiment

  Interestingly, the adjustment marks are provided at the downward curved edge of the spreading disc. This guarantees in a very simple way

  that the setting marks never come into con-

  tact with the fertilizer particles to be sprayed.

  According to another characteristic of the in-

  vention, the pivot pin has a toothing and that the different teeth form the pins

  According to another characteristic of the in-

  The adjustment markers are provided on adjustment jigs and these are placed in holes provided in the spreading discs to enable the exact adjustment of the projection members.

  According to another characteristic of the in-

  vention, the setting marks are dies in

spreading discs.

  Finally, according to another characteristic of the invention, the adjustment marks are in the form of

parts made of synthetic material.

  FIGS. 2 and 3 show the spreading discs 11 juxtaposed and the projection members 12 carried by the discs 11. These spreading members 12 can pivot angularly on the spreading discs 11. For this, the axis of pivoting 13 of each spreading member 12 is in the half of the spreading member 12 of the respective disc 11, near the axis of rotation 14. The pivot axis

  13 is in the form of a hinge pin 15. The mechanism
