Embodiment Construction

[0035] [35] According to the invention, the cutting bar housing of a disc harvester is formed from two metal plates formed in a forming operation before assembly.

[0036] [36] Figure 1 shows the profiled upper panel 1 of the box with a downwardly bent portion for forming the rear edge 2 of the box.

[0037] [37] Figure 2 shows the profiled lower panel 3 of the box, which comprises an upwardly bent front edge 4. Advantageously, the lower plate also has a substantially vertical partition 5 obtained by bending. This partition 5 is located near the rear part of the case in order to increase the rigidity of the case and limit the volume in which the drive gear is located. This definition of volume allows, for example, to reduce the amount of lubricant required for the gear to function well.

[0038] [38] The two plates, the lower plate 3 and the upper plate 1, are brought into contact with each other so that the front part of the upper plate 1 rests on the flat part of the front...

Abstract

The invention relates to a method of producing a housing for a mower cutter bar and to the housing thus produced. The invention is characterised in that it comprises the following successive steps consisting in: forming the upper plate (1) and the lower plate (3) of the housing; assembling the formed upper plate (1) and the formed lower plate (3) by means of welding in order to form a casing (6); and cutting holes (7) into the casing (6) using a laser beam, said holes being intended to receive the disc bearings and the intermediary drive pinions.

Description

technical field [0001] [01] The present invention relates to a method for implementing a cutting bar box for a disc harvester and the resulting box. Background technique [0002] [02] The disc harvester comprises a very large cutting bar, the size of which can reach more than four meters, and the cutting bar has a plurality of rotating discs, and the function of these rotating discs is to cut the vegetation. [0003] [03] The turntable is mounted on bearings arranged at more or less regular intervals on the cutting bar. These turntables are driven in rotation by a gear mechanism contained within a sealed housing containing a lubricant such as oil. [0004] [04] The gear mechanism is actuated by a transmission capable of transferring the necessary energy from the vehicle, typically a tractor, to the tank. [0005] [05] It is important that the cabinet is relatively light and soft in order to better follow the unevenness of the ground. The housing should also be completely ...
