  MOBILE APPARATUS FOR ASSEMBLING AND STACKING

GRAMINACEES BALLS.

  The present invention relates to a mobile apparatus for gathering and stacking boots or balls of

  graminaceous collected on the ground or brought

  Seuse-press. To save labor when picking up and loading graminaceous bunches

  on the spot, the most

  towards. the simplest devices of this kind are

  frame-shaped structures which, placed in front of a trac-

  or hung on the baler, allow the bales to be pushed or pulled on the ground

  dragging until a determined quantity of bal-

  was obtained; when you release a lock, you

  puts the frame to be removed from the group of balls and to be refilled. With this kind of apparatus balls are

  disordered heaps, which presents the double in-

  agree that the bales are soiled during pick-up and must be picked up individually to

on a transport vehicle.

  Complex assembly apparatuses and more expensive construction allow the bales to be arranged neatly and / or transported to the depot on moving assembly trays. Groups thus formed of balls arranged in an orderly manner in

  a plan can be raised as is through the grif-

  accordingly, a front loader for trac-

  and be stacked or transferred on a transport vehicle group by group. In this case, the claws of the front loader are made in such a way that when the front loader comes in contact with the group of balls, the teeth of the claws penetrate individually.

  in the corresponding bales, thus allowing the

  the ball group seems to be raised and again

placed at the desired place.

  A disadvantage in this respect is that this

  yielding and mechanized transfer of bales can only be implemented for a specific gravity

  not exceeding 120 to 130 kg / m3. If the balls are

  at higher density, which is more and more required in practice, then the teeth of the claws no longer enter the bales when the front loader comes into action so that the latter can not be lifted.

  In some areas, it is customary to leave

  dear graminaceous balls on the field. Considering

  these balls are as much as possible

  in groups of eight or ten for the balls to be protected from the rain. In these regions, we know

  devices which, attached to the baler,

  - such piles and deposit them on the field. Being

  given that in this case the bullets are superimposed

  they are not sufficiently

  especially when transferring batteries to vehicles

  transport cases. To overcome this disadvantage, a stacking apparatus is known which forms such stacks and allows the balls already bound by means of string to be tied together to keep them in the stack. The high construction cost and the strong

  twine consumption that this solution causes con--

  are serious disadvantages.

  Increasing straw surpluses lead to a reorganization of the use of straw. In this regard,

  more and more straw is needed.

  can be transported over often large distances.

  In order to use the available transport space in a more cost-effective way, grasses need to be

  under these conditions be compressed to a larger den-

  site and therefore become heavier. These balls can no longer be handled manually but only by mechanized means. The known gathering devices of bales are not suitable for this work because of the disadvantages mentioned.

  The present invention creates a mobile device des-

  used to gather graminaceous bales and by means of which even dense and heavy graminaceous bales can be stacked mechanically so that the piles also have sufficient cohesion when transported on transport vehicles.

  to be tied. This goal is achieved in the case of a

  mobile device of the kind described above by an inclined carrier whose upper end located on the side of its

  exit is followed by a platform to which

  a transverse displacement mechanism as well as a

  mechanism for rotating and advancing bales, the platform

  form being followed, on the opposite side to its receiving end

  trice, a stacking grid that can be lowered to different positions in height and to be immobilized

in these.

  Particular embodiments of the present invention

  invention that allow the stacking process

  to be carried out automatically, in such a way as to

  as possible and without incident are described below. The invention is explained in more detail below

  with the help of an exemplary embodiment illustrated schematically

  1 is a perspective view, in the unfilled state, of the mobile apparatus for collecting graminaceous bales; FIG. 2 is a fragmentary view on a larger scale of the apparatus of FIG. 1;

  FIG. 3 represents, in a side view, a part

  part of Figure 1; Figure 4 shows a four-layer bale assembly;

  FIG. 5 represents the hydraulic maneuvering system

  hydraulically controlled hydraulics; and Figure 6 shows a stack of three-ply bales. The mobile frame 1 is coupled with its drawbar 2 to a baler represented in part in FIG. 3. The bales are transmitted by the baler to the conveyor chain 6 which receives the bales.

  after the others and carries them on the platform 7.

  Cover brackets 8 and a stopper 9 re-

  hold the balls on the platform 7. The

  9 can with the aid of the hydraulic cylinder 10 be brought to

  from the stop position to the passage position.

  To move the balls laterally it moves in the

  slots 11 of the platform 7 a pendulum 12 which is ar-

  tailed on the drawbar 2 in the supports 14 and moves to

  medium of the tube 15 located at the upper part of the balan-

  bale the bales laterally using the hydraulic cylinder.

  16. When a ball has been moved laterally, the rocker 12 returns to its starting position (figures

  1 and 2). The next ball brought by the transport chain

  6 on the platform 7, remains parallel to the first ball shifted laterally. Then a lever 19 for rotating balls is brought by means of the cylinder 3 to rotate from the position shown

  in solid lines in FIG. 2 in the position represented

  is shown in phantom so as to be in front of the front faces of the two balls A and B. Ensuitele support in the form of a frame 13, in which are mounted on the one hand the lever 19 so as to pivot and on the other hand the cylinder 3 acting on this lever 19, is pulled by the cylinder 20 in the direction of the arrow Z by sliding in the bars 5 until the balls A and B are on the carrier grid 21. In order to reduce the friction , the frame-shaped support 13 is mounted to move by means of rollers 13 'in the bars, which are fixedly connected to the frame 1 of the apparatus. For the sake of clarity, the equipment 18 for the movement of the bales is shown only partially in FIG. 1. The programmed cycle can be, for example, such (see level 1, FIG. 4) as the two balls A and B disposed parallel to the running direction succeeds a ball C disposed transversely and there followed two parallel balls D and E. The next ball C brought on the platform 7 by the conveyor chain 6 must be turned by the lever 19 of 90 and, by a movement of the equipment advancing balls 18 towards the rear,

  be slid on the carrier grid 21 so as to be

  against balls A and B on that

  Niere. For this purpose, the ball advancement equipment 18 is first brought back to the position shown in phantom

  in FIG. 2 and the ball C is then transported

  7. The frame-shaped support 13 is then moved sufficiently by the jack 20 so that the pivoting lever 19 is next to the ball C. Then, because the lever 19 pivots under the ball action of the cylinder 3 in the position shown in phantom, the ball C is rotated 90 and is therefore placed transversely to the balls A and B. During this rotation operation

  Slide 17 (Figure 1) prevents the ball from falling out of it.

  platform 7. After being shot, the ball C is ti-

  actuated by the actuator 20 against the balls A and

  B on the load-bearing rack 21. The two last-

  Balls arranged parallel D and E of this level 1 is accomplished as described for the first two balls

  A and B; during the latter transport, the balls are

  already on the middle part of the carrier grid 21 are brought to the end of the carrier grid which is now provided with a layer of bales (see level 1,

  Figure 4). To free up space for the ball coat

  the following ones, the carrier grid goes down from a step under

  the action of the hydraulic cylinder 22, then on the first cou-

  the rear end is provided at the end of the

  bullets look a flap 23 that can be pulled towards the

  top by a hydraulic cylinder 24 before the ejection of the

seems from the stack of bullets.

  When the carrier grid 21 is loaded with the

  seems to be four layers of bullets (levels 1 to 4,

  re 4), she is brought down, under her own weight

  and by the outlet of the piston rod 22 'of the cylinder

  hydraulic cylinder 22, to the ground, a cable

  2 "being for this purpose on the one hand connected by means of a pulley to the piston rod 22 'and secondly fixed to a cross member 26' which can in turn move

  up and down in guides 26 "and to-

  which are fixed the teeth-shaped bars 26 of the

  carrier grid 21. The guides 26 "have their ends

  The lower rollers 36 of the cross member 26 'fit into the curved portions of the guides while the upper rolls 37 remain in the rectilinear portions of the guides during the downward movement of the gate. As a result, the crossbar 26 'and the shaped bars

  of teeth 26 connected to the latter take an in-

  cined, so that the layers of bullets can be going on

  walk off the device or be ejected from it

  this. This ejection can be achieved for example by means of a sliding unloading member 25 which during

  lowering the grid 21 is anchored in the ground and pushes

  the stack of balls of the carrier grid while the machine rolls on the ground. The empty carrier grid 21 is now brought back by the hydraulic cylinder 22 in its

  position and during this raising of the grid

  the unloading organ 25, maintained by a cable

  (not shown) passing over return pulleys, sliding

  is along the teeth-shaped bars 26 of the grid

  carrier to return to its starting position.

  Figure 5 shows the hydraulic maneuvering system

  electrically controlled and comprising the hydraulic cylinders

  hydraulics 10, 16, 20, 22, 24 and 3, the oil-hydraulic motor

  28 and the corresponding distribution valves 32

  as well as the pump 29, the oil reservoir 30 and the

  The two hydraulic cylinders 20 and 22 associated respectively with the bale feed equipment and the carrier grid operate not only with a starting position and a terminal position at

  and b but with a starting position, a terminal position

  and intermediate positions determined by

  electric limit switches, these differences

  your positions being designated by a, b and c for the cylinder

  20 and by a, b, c, d and e for the hydraulic jack

  22. The programmed automatic control of the system

  hydraulics, carried out using drum combiners

  bour or the like, for the realization of the layers

  bales and batteries shown in Figure 4 are

  the following way. For level 1 training,

  the cycle begins with the activation of the oleohy-

  hydraulics driving the conveyor chain and which allows the first bale to be transported on the platform 7 to the stopper 9, and then the balance leaving its starting position under the action of the hydraulic cylinder 16 passing its position a at its position b pushes the ball laterally, after which the jack 16 returns to

  its position is such that the balance 12 returns to its po-

  initial session. This displacement of the first ball can

write briefly: 28, 16a-b-a.

  The next ball, pushed by the press or an ap-

  such a collector on the conveyor cat6, is also

  transported by the oleohydraulic engine 28 on the

  platform 7 to the stopper 9 and is placed parallel to

  next to the first ball. Then the cylinder 3, passing from the position a to the position b, rotates the lever 19 of the equipment advancing balls 18 and the

  cylinder 10 associated with the stopper is this one in step-

  from its position a to its position b so as to release the passage so that the cylinder 20 associated with the ball advancement equipment 18, from its position a to its position È) can fire the first two balls on the

  21. By moving from its position b to its position

  a, the jack 3 allows the lever 19 to be returned to its starting position by pivoting, the jack 10 associated with the

  stopper brings the latter back into the closed position

  from b to a and the cylinder 20 associated with the equi-

  Advancing balls 18, from c to a, slides this equipment into the starting position of the next cycle. This process can be written briefly

  28, 3a-b, 10a-b, 20a-c, 3b-a, 10b-a, 20c-a.

  The third ball is shot using the same

  mechanisms and slipped by them against the first two

  bullets arranged parallel to the direction of mar-

  che on the carrier grid. The process begins with

  in operation of the oleohydraulic engine 28 which allows

  the ball to be transported by means of the trans-

  carrier 6 on the platform 7 to the stopper 9,

  then the stopper is brought into the open position

  Since the jack 10 changes from a to b, the jack 20, from a to b, pulls the bale advancement equipment and now the pivoting lever 19, actuated by the jack 3 from a to b, rotates the bale 900 and pulls the bale on the carrier grid with the cylinder 3 passing from b to c, the cylinder 3 rotates the lever 19 in its previous position from b to a, the jack

  10 associated with the stopper brings the latter back into position.

  closing from b to a and the cylinder 20, from c to a, brings the equipment forward balls

  18 in his new starting position. This process is

  briefly written: 28, 10 a-b, 20 a-b, 3 a-b, 20 b-c, 3b-a,

b-a, 20 c-a.

  The fourth and fifth bullets of level 1 are again slid longitudinally in the direction of travel on the carrier grid, as already described for

balls 1 and 2.

  When the five bullets are now all

  on the carrier grid and the mechanisms have been

  born in their starting position, the cylinder 22 for the

  the lowering and lowering of the carrier grid

  and passes from a to b so as to lower the carrier grid 21 by a distance corresponding to a layer of

  ball; this operation is written briefly: 22 a-b.

  The series of programmed operations necessary to obtain the longitudinal position of balls such as

  1 and 2 as well as 4 and 5 and the rotated or trans-

  bullets such as 3, which sequences of operations are called I and II respectively, are repeated now

  at will according to the desired stacking order. Lob-

  retention of the stack shape shown schematically

  in Figure 4 requires the automatic program cycles

  following: Level 1 I 28, 16 a-b-a, 28, 3 a-b, 10 a-b, 20 a-c, 3 b-a, 10 b -a, 20 c-a

  II 28, 20a-b, 10a-b, 3a-b, 20b-c, 3b-a ,.

  b-a, 20 c-a I 28, 16 a-b-a, 28, 3 a-b, 10 a-b, 20 a-c, 3 b-a, 10 b-a, 20 c-a, 22 a-b Level 2 II Level 3 I Level 4 II

  In this way can be obtained by following

  any programmed operations of multiple

  layers of bullets and therefore various forms of

  my batteries. Thus can also be composed of

  two or three layers. Below are the sequences of operations

  programmed to obtain a stack of three

  such as the one shown as an example on the

  Figure 6: Level 1 II Level 2 I Level 3 II II 22 b-c 22 c-e II 22 a-b 22 e-a The programmed control can in part be further simplified eg by allowing the stopper 9

  to be kept in his stopping position not by a

  10 but by means of a tension spring or compression so that the tab deviates under the effect of the pressure exerted by the balls sliding back to be brought back then in the position

stop by the spring.

  The weight, dimensions and shape of the batteries de-

  are chosen in such a way that the batteries can be

  to be loaded mechanically by means of

  tractors on transport vehicles and that the loading space available on them

be used to the maximum.

  Instead of being hitched to a collector-press,

  it is the case in the exemplary embodiment shown, an apparatus according to the invention can also be provided with a known equipment for picking up balls, mounted in front of the conveyor chain 6. The apparatus according to the invention can be coupled directly to a tractor or in the form of a self-propelled implement equipped with a traction group, a transmission, a steerable axle and

a steering system.
