Harvester,

The invention relates to a combine harvester of the kind., Which comprises a table. Which is relative to the floor adjustable in height and which carries a pick-up, for example, a conventional cutting blade., Or that includes a topper _s in which the pick-up a Having shear bar., Which consists of a series of fingers _D which come into engagement with the crop below the heads, which are cut off by a knife »

The invention relates to a combine harvester the front end carries a height-adjustable table, This combine harvester is characterized according to the invention. That the table with the frame of the combine harvester is connected by a substantially parallel linkage so that the table is in the positions in which is adjustable in height, is held at a substantially constant angle for operating.

The table can carry a shearer and a knife., which hold the same in the different setting heights at an essentially constant angle to the operating -

One of the links of the parallel linkage can arj.s an elevator "

The following is an example embodiment the invention described with reference to the drawings, shows in multiple terms;

Fig. 1 is a side view of the front end portion of a Combine according to the invention from the designated as Köpfer Kind and

FIG. 2 is a perspective view corresponding to FIG. some parts are broken off for the sake of clarity ο

The front end portion shown in the drawings for the topper includes an elevator and in the same opposite parts of the elevator includes a housing 10, through the upper end of a shaft 11 _s to pass the chain wheels bears. At the lower end of the housing 10, two rollers 13, 14 are arranged and the chains of a conventional undershot chain and slat conveyor 15 are placed around the chain wheels 12 and the rollers 13 * I ^,

The rollers 13,14 are carried by the lower ends of pairs of arms 13A, 14A, the upper ends of which are connected to a shaft 10A im. Housing 10 are articulated = the shaft 10A is movable by adjusting screws 10B in the longitudinal direction of the housing, an adjusting screw 16A

and a spring arrangement l6B are provided for adjusting the angle between the arms 13A., l4A =,

In this way the tension in the chains of the conveyor can be adjusted. On the frame of the combine harvester the shaft 11 also acts as a pivot for the elevator _c A mounting frame 1γ is provided with a pair of lugs or plates l8 stick out to the rear. The plates lie on each side of the side walls IQ of the elevator and are arranged on pegs 20 which are fastened to the side walls 19. _s The plates 18 are connected at their upper ends by a cross frame member 21 and shaped U-at their lower ends by a part C.2., so that a generally rectangular opening is formed. passes through plural marriage the crop to the elevator, Outside each plate 18, a reinforcement rail 25 is arranged at a distance from it. The rails 23 serve as external supports for pegs 24 which protrude laterally from the plates 18. Link arms 26 extend generally parallel to and above the axis of the elevator 15. Their rear ends are connected in an articulated manner to the frame 16 of the combine harvester by a torsion bar 27. Each handlebar is provided with a plurality of stanchions 31 so that the length of the resulting handlebar unit is adjustable. Hydraulic pressure cylinders J52 are pivotably mounted at the lower end on brackets 33, which are attached to the frame 16 of the combine harvester and at the upper end with pivot pins 34 articulated on the associated

push

. Handlebars 26 are provided. The Heraur ^ -ste-e ^ or drawing in the piston rod of the pressure cylinder therefore causes

that the link arms 26 are raised or lowered together with the elevator and the mounting frame. Due to the generally parallel arrangement of the link arms 26 and the elevator, the mounting frame 17 maintains a substantially constant angle to the ground. In addition, the plates 18 extend sufficiently far to the rear over the front end of the elevator so that, despite the articulated connection of the frame 1'f to the elevator, there is no gap between them.

A table 37 supports a shear bar with fingers 37A. ₅ between which ¹¹ the crop is picked up, with the heads above the fingers. 37A are located at the

downward movement of the table "the heads are cut off at the rear ends of the pingers 37A by the cutting knife 38 and fall onto the bed 39 of the table 37 '. The heads are then collected in the usual manner by a screw 40 and an inserting tray 41 and in bringing the center of the table 37 _s they are fed to the elevator from where.

The table 37 is connected to the fastening frame VJ by hooks 42 which are located on the rear side of the table and which engage around the pins 24. The table is held in position by latches 43 - each latch 43 consists of a bracket 44, which protrudes rearward from the U-shaped part 22 of the mounting frame V ( . A lever 45 is pivotally mounted on the bracket 44 at 46 and a The locking rod 47 is articulated at 48 to the lever 45. The locking rod 47 carries at the front end a pawl 4.9., Which comes into engagement with a part 50 of U-shaped cross-section.

which forms a floor reinforcement of table 37 " On the lever 45 there is a handle 51 for actuation the locking device attached-. The latches 43 are eccentric. That means. That the pivot 48 is in the locking position above the line. Which is between the point of contact of the pawl 4.9 with the U-shaped part 50 and the Trunnion 46 extends ■. In the unlocked position is the pivot 48 below this line-

This arrangement gives the "possibility of easy Exchanges, for example. Between-the head table and the usual table of the combine harvester. It also enables the table to be removed quickly so that the entire

• ^ 'width' can be reduced. For acceptance of the table is only required to pivot the handle 51 in the Uhrseigersinn to unlock the latches Q4 "The 'table can then be lowered to the ground or to a trolley, by retraction of the piston rods of the pressure cylinder 32nd so that the hooks 42 automatically disengage from the pins 24.

As already mentioned above, the fastening frame 17 remains in a substantially constant position to use “Since the table with the mounting frame is connected, the table 37 and fingers 37A remain. of the shearbar, as well as the knife 38 also in one substantially constant position, which by adjusting the length of the link arms 26 for different The conditions of the harvested crop can be easily changed o
