Problems solved by technology

The reason is that if the cut crop is not properly fed, the crop will block the working area of ​​the cutting elements, reducing the cutting performance of the mower
In practice, it has been found that poor delivery of the cut crop will cause the cutting device to jam, that is, the rotation of the cutting member will be blocked

Embodiment approach

[0051] According to another exemplary embodiment not shown in the figures, the casing 9 is a modular shell. The meaning of this sentence means: the casing 9 is a collection of modules, these modules are combined with each other, and each module supports a cutting member 7a-7e. In addition, the transmission element arranged in the casing 9 may also be constituted by a transmission shaft, an idle gear (including a bevel gear), a chain or any other existing devices.

[0052] The supports 17a-17e of the cutting devices 7a-7e may have different shapes, eg may be circular or triangular, and may support different numbers of cutting elements 11a-11e.

[0053] According to another exemplary embodiment not shown in the figures, the number of cutting members 7 a - 7 e provided by the cutting device 4 is a different value greater than two. In addition, as long as the rotation directions (10b, 10c; 10d, 10e) of at least two adjacent cutting members (7b, 7c; 7d, 7e) are opposite and conver...

Abstract

The invention relates to an agricultural machine which is fitted with a chopping device (4), said chopping device (4) comprising: a guard (9); at least three chopping members (7a, 7b, 7c, 7d, 7e) which are disposed above said guard (9) and which are linked thereto so as to pivot around a shaft (8a, 8b, 8c, 8d, 8e) which is directed upwards; transmission elements which rotate said chopping members (7a, 7b, 7c, 7d, 7e) around the respective shafts (8a, 8b, 8c, 8d, 8e); and, among the chopping members (7a, 7b, 7c, 7d, 7e), at least two adjacent chopping members (7b, 7c, 7d, 7e) which rotate in opposite directions (10b, 10c; 10d, 10e) converging towards the front. The inventive agricultural machine is characterised in that the distance (12) separating the rotary shafts (8b, 8c; 8d, 8e) of two adjacent chopping members (7b 7c; 7d, 7e) rotating in opposite directions (10b, 10c; 10d, 10e) converging towards the front is greater than at least a distance (13, 22) separating the rotary shafts (8a, 8b; 8c, 8d) of two adjacent chopping members (7a, 7b; 7c, 7d) having directions of rotation (10a, 10b; 10c, 10d) which do not converge towards the front. The arrangement of said chopping members (7a, 7b, 7c, 7d, 7e) in this manner can be used advantageously to improve the removal of the chopped product towards the rear of said chopping device (4).

Description

technical field [0001] The technical field to which the present invention pertains is that of agricultural machinery in general, and the machinery involved is directed especially to lawnmowers or mower-conditioners. [0002] More specifically, the invention relates to an agricultural machine equipped with cutting means comprising: [0003] - a casing; [0004] - at least three cutting members arranged above said casing and connected to said casing such that they are pivotable about respective vertical axes; [0005] - transmission elements that drive the cutting members to rotate the cutting members about their respective axes; and [0006] - Among the several cutting members, the rotation directions of at least two adjacent cutting members are opposite, and the two rotation directions converge toward the front. Background technique [0007] Agricultural machines of this type are known in the prior art, in particular from patent document EP1002458 A1. In fact, this docum...
