Description

"Adapter suspension on combine harvester".

  The invention relates to an adapter suspension on a combine harvester, wherein the adapters are connected to the conveyor well of the month.

  threshing machine so that a hung movement

  the adapters is possible in a long,

  dinalement and transversally to the direction

walking.

  We already know suspensions of adap-

  of this type in different executions.

  In the DD-PS 94,725 patent is described a solution in which the adapters have, in the axis, at the bottom of their rear wall, a point of articulation relative to the conveyor well, around which they can perform a pendulum motion in both planes. In the upper front zone of the conveyor well is taken up a pendular support which rests in the axis, runs transversely with respect to

  the direction of travel is guided in the lateral

  of the conveyor well, in lights and can

  rotate in a vertical plane. Above the hanged support

  On both sides, outside the conveyor well, sliding guides run horizontally and are connected by an arch. Springs

  pull the arch to unload the adapter.

  In addition, the adapters, which include staves

  open at the bottom, come above the

  smoothing. During the uprising, the adapter is pulled towards the conveyor well by means of a traction cable having several changes of direction, recalled by a spring and coupled to a cylinder of the

conveyor well.

  In the combine E 516 (Combinat Fortschritt landmaschinen), this solution is implemented in a variant form. We gave up here

  sliding guide and arch. The scope of the adaptation

  are placed immediately above the pendulum support to which the discharge springs are also connected. The spans have, in the horizontal direction relative to the pendulum support, a large clearance which corresponds to the maximum pivoting zone of the adapter relative to the direction of travel. the

  the traction cable is placed on the upper surface

  of the conveyor well, between the discharge springs, a hydraulic cylinder whose front hook is housed in an eyelet of the adapter and thus pulls it in the direction

  of the conveyor well during lifting.

  In the case of these solutions, relatively large losses of cereals occur, especially in the case of small grains, at the point of transition from adapter to conveyor well. In addition, there are many coupling points between the adapter and the conveyor well that must be connected or separated during the installation and removal of the adapter. It thus appears a relatively important manual work. Due to the many sliding guides, there is also significant wear. At the same time these sliding guides represent a significant inertia of the adapter to follow the profile of the ground. Another disadvantage of these solutions is that these suspensions require specially designed adapters which can not be reused on other machines, for example machines for harvesting fodder products. This

  leads to high expenditure in manufacturing and in the use of

  sateur. The purpose of the invention is to design the adapter suspension on a combine so as to reduce cereal losses at the transition point between adapter and conveyor well, to allow a quick and easy installation or removal of the adapter and allow to follow with precision and ease the soil profile. We must also be able to reduce the expenditure of

  point of view of the multiplicity of adapters.

  The object of the invention is to create an adapter suspension on a combine harvester for

  adapters arranged, with long pendulum

  transversely to the direction of travel against the conveyor well of the combine, having an upper pendulum support pivotable in the vertical plane and on the outer ends of which adapter seats comprising a discharge device for the adapters, suspension which allows a simple and safe seal between adapter and conveyor well, which is done with few coupling points, in addition to which sliding guides are dispensed with and in which adapters can be made in such a way that they can

  also be reused on machines that do not require

  do not sit in two planes.

  This goal is achieved by the means

  front end of the conveyor well, near its lowest point, is articulated a frame that can pivot forwards and on -the lower crossbar which is inserted, in the axis relative to the well of the conveyor, a pad directed in the logitudinal direction of the vehicle. In the pad engages a pin of the adapter. The pendulum support is guided, in the upper crossbar of the frame, in side lights and, at the upper crossbar, is connected the fixed discharge device

  in addition to the conveyor well. The scope of the adaptation

  the form of the pendulum support and against the frame are arranged, on the side and from below, guide plates, movable whose ends come

  inside, against the conveyor well.

  The pivoting movement of the adapter

  which appears when following the soil profile, longitudinally with respect to the direction of travel,

  is transmitted directly from the adapter to the frame

  the adapter reaches and through the

  pendulum support and taken back through

  frame reach on the conveyor well. The provision

  discharge device, connected to the top cross-member of the frame, provides a constant and low ground pressure

  the adapter. The movements of the adapter that appears

  transverse to the direction of travel are taken up by the rotation of the pin in the bearing

  and are taken up by a vertical pivoting of the support

  duly through the scope of the adapter.

  The guiding plates, which guarantee a transfer, sealed for cereals, between the frame and the conveyor well, can, thanks to their mobile attachment to the frame, adapt to any modification of inclination between

the frame and the conveyor well.

  According to the invention, it is furthermore

  to provide that the frame reaches on the conveyor well on the one hand and the pad on the frame on the other hand are arranged at the same height and that the frame, side

  adapter, and the adapter, frame side, comply with

  a flat bearing surface to serve as an opening for

  recovery and surrender for harvest. This is advantageous for easily following the soil profile and gives a particularly good seal between adapter and frame.

  According to the invention, it is furthermore

  to provide that on the side of the conveyor well is fixed a pendulum limiter and that above and below the pendulum limiter there are stops fixed to the adapter. With these stops we get a

  the technically necessary limitation of the

  transversely pendulum adapters, being specified that the forces resulting from the fact that shunting the pendulum device itself are directly in the conveyor well. To reduce the stress peaks, we can give here a conception

  elastic with pendulum limiter or stops.

  Finally, it is advantageous to provide that on a bearing surface of the pendulum limiter rests, by a roller, a lever on the adapter and whose

  the other end is connected to the adapter via

  of a tension spring. With this lever we obtain a mass balance of the adapter transversely to the direction of travel and therefore a balance

static stable.

  With the adapter suspension according to the invention, the losses of the harvest at the point of transition between the adapter and the conveyor well are considerably reduced. The installation and removal of adapters can be done quickly and easily. Any additional mating elements that are not needed for the adapter drive will disappear. Since the pendulum range is transformed into several rotating bearings and the sliding guides are dispensed with,

  also increases the freedom of operation of the

  pension of the adapter and therefore improves the monitoring of the soil profile. Due to the plane connection of the adapter against the frame, without relative displacement, longitudinally

  relative to the direction of travel, between the two

  these adapters * may also be used, without modification of connecting pieces and connection surfaces, in machines for which only a single plane is required to swing in a single plane, or for machines for which the adapters are rigidly mounted on a set of the machine. This lowers the expense when making different adapters. At the same time, the user only needs one set of adapters for several different machines, for example for the combine harvester,

  the chopper and the swather.

  The invention is explained in detail below in an exemplary embodiment. In the accompanying drawings:

  FIG. 1 represents a cinematic diagram

  of the adapter suspension,

  FIG. 2 is a side view of

  of a combine harvester, FIG. 3 is a section according to FIG. 2, FIG. 4 is a partial section, taken longitudinally with respect to the direction of travel, of FIG.

the adapter suspension.

  A combine 1 has, before its drummer 2, a conveyor well 3 which can

  rotate vertically. For this pivot, between the month-

  combine harvester 1 and the conveyor well 3 are

  two hydraulic cylinders 4. At the point before the lowest of a reinforcement frame 5 of the conveyor well 3 is

  connected, via two staves 8 placed laterally

  Normally, a frame 6 with its lower cross member 7. At the height of the connecting line of these bearing surfaces 8 is further inserted in the lower crossbar 7, in the axis relative to the conveyor well 3, a bearing 9 open towards the high and directed in the direction of walking. An adapter, for example a cutting table with a cutterbar

  11, a reel 12 and skids 13, whereby the adapter

  10 is resting on the ground, has, on its rear wall, placed in the axis and at the bottom, a pin 14 which comes to

  housed in the pad 9 and a pin 15 locks.

  The adapter 10 and the frame 6 rest against each other

  by flat bearing surfaces 16; 17 surrounding the

surrender and recovery window 18.

  The upper cross member 19 of the frame 6 carries a pendular support 20 guided in the slots 21,

  with the possibility of pivoting about-near-in the vertical plane.

  The bearing surfaces 22 of the adapter 10 are housed, in the form, above the two outer ends of the pendular support 20. In addition, discharge springs 23 and a coupling element 24, connected to a hydraulic jack 25, the discharge springs 23 and the hydraulic cylinder 25 are articulated to a support 26 of the

conveyor 3.

  To seal the frame 6 by

  relative to the conveyor well 3, are reported, laterally

  and at the bottom, against the frame 6, movable guide plates 27, the ends of which come into the conveyor well 3 and that springs 28 apply against this well. To limit the transverse pendulum movement, a pendulum limiter 29 is furthermore fixed on the side of the

  conveyor well 3, directly at its front end.

  Above and below the Pendulum Limiter 29 are

  stops 30 fixed to the rear wall of the adapter 10.

  In order to guarantee a static balance of the masses and to obtain the equilibrium of the adapter 10 in the transverse direction, there is furthermore, on the pendulum limiter 29, a bearing surface 31. On this bearing surface rests, by the intermediate roller 32, a cranked lever 33 which, in its center, rests on the adapter-10. The other extremity

  lever 33 is connected to the adapter 10 via

of a tension spring 34.
