Abstract

a) Fertilizer spreader fed up to the adjustable outlet from the feed tank to the spreading member, b) characterized in that in the feed tank (1), upstream of the outlet (7), there is a screen (13) which extends obliquely downward in the direction opposite to the direction of transfer (8) of the conveyor belt (4).

Description

"Fertilizer spreader fed to the adjustable outlet of the

  The present invention relates to a fertilizer spreader, in particular for dispensing grain-shaped products, comprising a frame, a set of wheels and a tank attached to the frame as well as to the minus one

  spreading device for distributing, in particular,

  granulated fats, receiving the products through

  a guided conveyor belt running around cylinders

  dres of return in the lower part of the tank

  this band from a front face

  at the outlet of the supply tank.

  Such a fertilizer spreader is already known from DE 33 13 892. This fertilizer spreader is provided with

  a feeding tank, elongated, the part of which

  is occupied by a conveyor belt passing

  on return cylinders and forming the bottom of the

  see. This conveyor belt drives the material of the

  to an outlet on the front of the tank. The quantity dispensed is determined by the size of the outlet orifice which is adjusted by means of a

  drawer in front of the outlet.

  Tank products may contain fertilizer clumps that lock in front of the exit port

  and may partially close this hole. This re

the quantity distributed.

  The present invention aims to remedy

these disadvantages.

  To this end, the invention relates to a fertilizer distributor characterized in that in the feed tank, upstream of the outlet orifice, there is a sieve which extends obliquely downwards in The direction

  opposite to the transfer direction of the transpor-

Teuse.

  Thanks to this means, it is guaranteed in a simple way that no fertilizer or other product that can not be

  crushed does not diminish the outlet or the mouth.

  In addition, the sieve ensures at least part of the crushing clumps which, thus reduced, can cross

the openings of the sieve.

  The sieve is fixed in a simple way if it is fixed above the outlet at the front wall or on the side walls of the tank, always at the level of the front wall and that its lower part

  leans against the lower elements of the side wall

  reservoir and / or against fixed abutment

to this wall.

  When the sieve is formed of branches allon-

  very prominent and with recessed sleepers, we have a

  advantageous embodiment especially for grinding the words

fertilizer.

  The present invention will be described below in more detail with the aid of an exemplary embodiment shown in the drawings, in which: - Figure 1 is a side view of a fertilizer spreader, - Figure 2 is a side view, in section and on an enlarged scale of the assembly of the sieve in the feed tank, - Figure 3 is a front view and at a different scale of the sieve, - Figure 4 is a front view and in section of the support of the sieve against the side wall of the tank, - Figure 5 is a side view of another

  fertilizer spreader with a sieve mounted differently.

  The fertilizer spreader consists of a feed tank 1, a frame 2 and a set of wheels 3. The lower part of the tank 1 is occupied by a

  transfer member in the form of a conveyor belt 4,

  dragged. In the rear part 5 of the tank 1 is the outlet orifice 7 adjustable by a drawer 6. The band

  conveyor 4 is driven in the direction of arrow 8.

  The conveyor belt 4 is driven from the tractor PTO, the transmission shaft 9, the screw transmission 10 and the return roller 11. The spreading device in the form of a spreading device 12 is preferably removably mounted in the area below the outlet 7 of the reservoir

feeding 1.

  In front of the outlet port 7 is a sieve

  13 down, in the opposite direction to the diagonally

  transfer station 8 of the conveyor belt 4; this

  set is hingedly mounted via a hinge 14 to the front wall 15 of the feed tank 1. At the lower lateral ends 16

  of the sieve 13 there are tamper-like abutment elements

  rubber pads 17 through which the sieve 13 comes into contact with

  and against the side walls 18 of the tank. If necessary, the sieve 13 can also be tilted into the

  position 13 'shown in dotted lines.

  The sieve 13 is formed of longitudinal branches

  the 19 protruding ones, these branches being constituted by

  flat irons; transversely to the branches there are

20 verses shaped round irons.

  The conveyor belt 4 transfers the products contained in the lower part of the tank 1 to

  the outlet port 7. Clumps of products

  The contents of the load and the non-crushable objects are retained by the sieve 13, at a distance from the outlet orifice 7. The pressure exerted on the clumps of material by the material transported, against the sieve 13, ensures the grinding of these clumps which, reduced to pieces,

  fall through the apertures 21 of the sieve 13 to arrive

  worm at the outlet 7 in the normal flow

of products transported.

  The sieve 13 is maintained in the re-

  presented by the traction springs 22 mounted between the

front wall 15 and the sieve 13.

  Figure 5 shows another fertilizer spreader with a sieve 23 longer. For some products, it is advantageous to use a sieve 23 longer than the sieve 13 according to Figure 1, the latter being arranged more inclined.
