Problems solved by technology

[0005] The problem with this system is that when you need to change the blade you need to loosen the bolt completely and that means a loss of time and if the change is made overnight , then the increased difficulty in performing said change and the increased risk of losing some bolts must exacerbate the problem

Embodiment Construction

[0027] Considering the numbering adopted in the drawings, the cutting device for a sugarcane harvester comprises support discs 1 each comprising a pair of guides 2 on which radial blades 3 are arranged, coupled to screw holes by Fixing bolt 4 in 11 makes radial blade 3 be fixed on the support disc 1, and fixation bolt 4 is set up in the nut, and nut is contained in the support disc 1. The aforementioned screw holes can also be incorporated directly into the support disc 1 .

[0028] The part of the cutting blade 3 with double cutting edge 5 protruding from the periphery of such a support disc 1 is the part that performs the cutting of the sugarcane during the continuous rotation of the support disc 1 incorporated in the cutting device of the harvester.

[0029] The radial blades 3 incorporate pairs of through notches 6 through which fixing bolts 4 are introduced, by the heads of which fixing bolts 4 the radial blades 3 are fixed on the support disc 1 .

[0030] Each through-s...

Abstract

This invention relates to a cutting device for sugar cane harvesters that includes several support discs, to which are fixed several radial cutters using fixing bolts, characterised in that the radial cutters (3) have several through-slots (6) that include a larger section enabling the passage of the head of the fixing bolts (4) and at least one narrower section that does not allow the passage of the head of the bolts (4), and into which are inserted the fixing bolts (4), said head of the bolts (4) being placed in line with the narrowest sections of the slots when the radial cutters (3) are in the active working position, in which case the head of such bolts (4) presses against the free face of the radial cutters (3) in zones adjacent to the narrowest sections of the through-slots (6).

Description

technical field [0001] As indicated in the statements of the present description, the present invention relates to a cutting device for a sugarcane harvester intended to perform the cutting of sugarcane during harvesting by means of radial blades included in a support disc of part of the device of the present invention. [0002] Therefore, the object of the present invention consists in specific fixing means associating the radial blades with the respective support disks, such that such means allow a faster change of the radial blades as they wear, in order to achieve the Better use of the blade. Background technique [0003] Currently, sugar cane harvesters have a disc in which the blades responsible for cutting the sugar cane are mounted. [0004] Most commonly two or three bolts are used per blade to thread the blades to the disc. [0005] The problem with this system is that when you need to change the blade you need to loosen the bolts completely and that means a los...
