Description

The invention relates to a manure spreader and the like.

  comprising a body provided with a movable bottom on

  the discharge side of which are arranged

  spreading comprising at least one horizontal gripping roller and a spreading table mounted lower and provided with spreading blades

  pandage above which a screen of redirection is placed

  formed by a pivoting closure wall and a pivoting frame. There are known spreaders provided with a dumping table and which have given very good results, in particular in

  spreading manure in agriculture.

  One drawback of these spreaders is that they only allow

  not spreading semi-liquid and pasty materials because this

  these flow out through the discharge part or-

  green of the spreader box and you cannot adjust the

  quantity arriving on the spreading table.

  Also when using a grain material, for example

  example of different mineral fertilizers, it's hard to

  hold a spreading with the desired precision.

  Another disadvantage of these spreaders is that their use

  possibly wider reading as a means of trans-

  postage is relatively reduced and concerns in particular only green products such as green fodder, hay, straw etc. These spreaders are not suitable for transporting very divided materials such as grains without doors, but also weeding plants because - as we have already said - they cannot

  not close. In the transport of weeded plants the pre-

  sence of the horizontal pick roller may damage

these.

  Also known are spreaders intended for spreading

  of pasty materials. These are of a tank type and used

  feels an ejection device comprising chains,

  heads, blades etc. However, they are not suitable for 1 '

  spreading solid matter or transport because their discharge-

  ment would involve appreciable difficulties. A spreader is also known in which the straightening screen is

  formed of a pivoting frame and a pivoting closure wall

  aunt who closes the open spill part of the box in its lower position and thus allows to transport

  different materials, including pastes.

  In the upper position, the pivoting closure wall then forms, with the pivoting frame, a straightening screen which plays the known role during spreading, that is to say it

  straightens the path of the materials in the desired direction

spread out.

  This spreader significantly expands the application possibilities.

  cation i.e. it can also serve as a means of trans-

  port but it still has some drawbacks.

  Since the adjustment of the flow diameter of

  the discharge part for spreading semi-material

  liquids (after transport of these materials by the spreader

  itself) is carried out by the operator, i.e.

  ci toggles and subjects the pa-

  king of pivoting closure and that between this adjustment and the moment when the tractor starts with the spreader, a certain amount of material,

  example of the liquid manure, flows outside so that it

  due to an irregularity in the distribution on the ground.

  Another disadvantage is that when the closet wall

  swivel frame is in the transport position, i.e. when

  that the discharge part is closed, the horizontal roller

  tal is located in the storage area of the spreader and more

  precisely in front of the pivoting closure wall.

  It is obvious that in the transport of certain materials

  res such as weeded plants, we cannot leave

  the horizontal roller in the storage area because the plan-

  yours would then be damaged by the cutting blades of the horizontal roller. It is therefore necessary, in such a case, to remove the horizontal roller, which places increased demands on the operation and possibly requires a

lifting mechanism.

  The object of the invention is to give the spreader a shape which makes it possible to transport and spread even pasty and semi-liquid materials and which does not require the horizontal roller to be removed from the storage area when transporting

  materials sensitive to mechanical damage.

  The invention essentially resides in the fact that a pa-

  king of pivoting closure engages in the storage part

  age of the body and is applied against the side walls and

  the movable bottom of the latter, in front of the horizontal take-up roller

  tal, the swivel frame being fitted with a hydraulic cylinder.

  Advantageously, for the introduction of the horizontal roller-

  tal or in case of damage to it, guides are pre-

  seen for the pivoting closure wall on side members or

on the till.

  Advantageously also, to relieve the hydraulic cylinder

  that on the side members are arranged as-

  subjectization that pass through the guides.

  An exemplary embodiment of the invention is represented by the appended drawings in which: FIG. 1 shows the spreader in perspective, the discharge part of the box being closed; - Figure 2 is a side elevation of the rear wall of the spreader also closed; - Figure 3 is a side elevation of the rear part and the partially folded closure wall and - Figure 4 is a side elevation of the rear part in the position where the frame assumes, together with the pivoting closure wall , the function of a

recovery screen.

  On the rolling chassis 1, fitted with wheels 11 and a drawbar not shown and connected to a source of motive power - the PTO shaft of the tractor - and to the hydraulic system, a box 12 is mounted at the rear. of which are arranged the known spreading members. It is a horizontal gripper roller 2 provided with a drive chain wheel 21 and known fingers not shown, arranged in a helix, and a

  spreading table 3 provided with spreading blades 31.

  The horizontal pick-up roller 2 is mounted in the rear part of the side walls of the box 12; this assembly can be in easily removable form. Chain wheel

  drive 21 meshes with the transmission chain 22

  dragged by a drive force transmission, not shown, used to drive the horizontal pick-up roller 2, the spreading blades 31 and the movable bottom 4 which is located in the lower part of the body 12 and which is for example under the

  form of an endless chain conveyor.

  Another possible solution has several rolls

2 horizontal overlapping takers.

  The spreading table 3 can be removable in a simple manner and it is pivotally and adjustable on the casing 32 so that it is connected to the end of

pouring of the moving floor 4.

  On the side members 15 of the body 12, the pivoting frame 5 is pivotally mounted by its supports 510 and carries pivoting securing struts 51, 52 provided with holes and making it possible to fix the frame 5 in the desired position.

  On the upper part of the frame 5 is hung a

  king of pivoting closure 50 provided with a band of elastic joint-

  tick 59, for example of rubber which, when the wall of

  swivel closure 50 is folded down, applies tightly

  che against the inner wall of the body 12 and the bottom mo-

  bile 4. In the case where the movable bottom 4 is formed of segments

  divided longitudinally and allows independent training

  dant, it is advantageous to use a joint tape 59 pre-

  feeling the outline of the movable floor 4.

  It is important that the pivoting closure wall 50,

  in its lowered position, is in front of the pre-roll

  horizontal neur 2 - as seen in the direction of movement -

  ment of the bottom 4- so that it separates the storage area from the box 12 and the spreading and dumping table. As a result, the horizontal pick roller 2 is separated from the storage area, which is particularly advantageous in the

  transport of weed plants and similar products.

  Between the pivoting frame 5 and the body 12 is interposed

  a hydraulic cylinder 6 which is connected to a pressure source

  known sion of a tractor not shown so that it conveniently makes it possible to raise or lower, from the tractor, the pivoting frame 5 at the same time as the closure wall

  pivoting 50. A position thus established can still be as-

  subject to securing struts 51, 52. These

  struts 51, 52 are mounted so that they can be inserted

  rer in the guides 71 arranged on the side members 15 or the

  body 12. On the pivoting closing wall 50 are available

  sés of the supports 53 by which the pivoting closure wall

  te 50 rests on the securing struts 51, 52,

  so that when lifting or lowering the frame

  Voting 5, one avoids the shocks of the pivoting closing wall 50 on the gripping roller 2. It is understandable that to avoid contact of the pivoting closing wall 50 with the gripping roller 2, the supports 53 can also be arranged on the body 12, the pivoting closure wall 50

then moving on these supports.

  The pivoting closure wall 50 arrives at the position shown in FIG. 4 by tilting on the pivoting frame and subjecting itself thereto by known means.

  In the spreading of manure, the pivoting closing wall

  te 50 occupies the position shown in Figure 4 o it plays the role of the recovery screen. The horizontal gripping roller 2, by its fingers, mills the fragments of the manure pushed through the movable bottom 4 and projects them onto the screen

  straightening from where they are projected onto the spreader blades

  dage in rapid rotation 31 which ensure the desired spreading.

  In the case where pasty or dry materials are used

  semi-licuides, the body 12 is closed during transport by the pivoting closure wall 50 as seen on the

  Figures 1 and 2. On the ground, we lift the wall

  pivoting and adjustable structure 50 by means of the hydraulic cylinder 6 to form the necessary slot and the semi-liquid or pasty material flows, using the movable base 4, onto the spreading table 3 from which it is dispersed by the spreading blades 31. In this case, the action of the horizontal pick roller 2

is not necessary.

  The position of Figures 1 and 2 is also advantageous for the transport of other materials, for example divided such as weed plants and similar products. In this case, if it is unnecessary to remove the pick-up roller 2, the pivoting closing wall 50 is raised when emptying

  loading to form the spacing of the quantity required

  and pushing the movable bottom 4, the contents of the box are emptied. In this regime, the machine described can very well play the role of a metering device inserted in a series of suitable machines. The proposed solution is naturally not limited to the described embodiment, whether it is the choice of material,

  spreading members, body shape, dimensions

  the movable floor, the number of hydraulic cylinders, etc.
