DE3139601C2 - Device for attaching a side cutter to a combine harvester - Google Patents

Abstract

The device according to the invention is used to mount a side cutting unit having a mower knife (19, 20) on a mower device (2) of a combine harvester (1) having a horizontal mower knife (3). In order to create a simple and compact design that is less prone to failure, a bearing holder (9) which can be attached to a stationary part (1, 7) of the combine and in which a shaft (12) is rotatably mounted is provided. At one end of this shaft there is a connecting lever (13) which can be connected to the mowing knife of the mowing device and at the other end a drive device (22 to 24) for the mowing knife (19, 20) of the side cutting unit is provided.

Description

The invention relates to a device according to the preamble of claim 1.

In a proposed device of the aforementioned type is to attach the side cutter on the combine harvester a base frame with several struts arranged at an angle to one another provided, the bearing points for the shaft, which is practically exposed over its entire length and must be shielded from the outside by a special cladding so that the risk of accidents is reduced is (DE-OS 31 19 938).

On the basis of the proposed device, the present application is based on the task of the Seitenschneidwcrk in a simple and compact and less prone to failure way on the combine to attach. This object is achieved according to the invention by the features in the characterizing part of claim 1 solved. The pipe section receives the shaft in a protected manner and can by means of a simply designed carrier and using parts that are already present on the combine harvester in a simple manner on the latter be attached. The entire length of the drive shaft is shielded from the outside by the pipe section so that additional shielding is not required. The one on two distant ones The side cutting unit also carries the pipe section that is supported in places.

The features of claim 2 relate to a simple part for the transmission of the drive from the Mowing device of the combine harvester to the cutting table and the features of claim 3 a preferred embodiment of the drive device for the mower knife or for the mowing knives of the cable cutter. Further advantages result from the remaining claim, the description and the drawing. In this is a device for the cultivation of a side cutting work on a mowing device of a combine harvester having a mower as an exemplary embodiment of the subject matter of the invention shown schematically. It shows

F i g. 1 is a side view.

2 and 3 each a section along the lines H-II and Hi-Hi in FIG. 1 each on a larger scale.

A combine harvester, which is only partially shown, has a stationary part 1 on which a mowing device 2 in The direction of travel is arranged transversely thereto and in front of the combine harvester. The mower has a of one mounted on the combine, not shown drive motor drivable, arranged horizontally Mower knife 3 on. On the mower knife 3 are on the side facing away from the combine harvester triangular knife blades 4 attached. The knife blades 4 run in a section of a stalk divider 5 on the stationary part I of the combine harvester is attached to the combine is also a bearing for the mower blade 3 in a manner not shown attached supporting side part, of which only an upper and lower frame part 6 and 7 are shown. the Frame parts 6 and 7 essentially form the shape of a triangle.

At the fixed part 1 of the mowing; etchers isi mitieleines console-like carrier 8 a tubular bearing holder 9 in a horizontal arrangement roped to the Combine and mounted in a parallel arrangement to the direction of travel. The storekeeper 9 is used for recording a shaft 12 mounted at its ends in bearing bushes 10 and 11. The shaft 12 carries at its in Fig. 1, the end shown on the left, a non-rotatably attached connecting lever 13, at its free end a roller 14 is rotatably mounted. The roller 14 engages in a U-shaped drive body 15. the on Mower knife 3 is attached. The connecting lever 13 can be released on the shaft 12 by means of a clamping device attached.

A support plate 16 is detachably fastened to the frame part 7 by means of screws which are welded to the bearing holder 9 is.

The storekeeper 9 carries on his in F i g. I right end in a can-shaped holder attached to it 17 a vertically arranged knife bar 18 in which two mowing knives 19 arranged next to one another and 20 are guided by means of knife holders 21.

On the in F i g. I end of the shaft shown on the right a double lever 22 is attached, at the ends of which in each case the same Abs'.and from the axis of rotation lower end of a connecting rod 23 b / w. 24 is stored.

b ¹ ) The respective upper end of the connecting rod 25, 24 is connected to one of the mowing blades 19 and 20, respectively.

In the holder 17, the cutter bar 18 is by means Screws fastened releasably. The storekeeper 9 can

by releasing it from the carrier 8 and from the frame part 7 and by lifting the roller 14 out of the U-shaped Drive body 15 can be detached from the combine harvester in a simple manner and also attached to it again.

The reciprocating movement of the mower 3 of the 5 combine harvester 1 is via the drive body 15 and
the connecting lever 13 on the shaft 12 mounted in the bearing holder 9 and thus on its at the other end
non-rotatably attached double lever 22 transferring. This drives the connecting rods 23,24, which the mower knives 19,20 back and forth movements accordingly
the drive of the mower blade 3 of the combine harvester 1
To give.
