US 2026/0026439 A1 · MODULAR AUGER UNIT AND HARVESTER HEADER

Abstract

A harvesting header having a transversal collector-conveyor auger, having a main module and lateral modules to extend its working width. Module end flanges are a pin-guides for preliminary alignment. Thereafter bolts are inserted inside a threaded bushing screwed into one of the flanges until it bottoms out against the other flange having a smaller hole to allow only the bolt to pass. The bolt is tightened with a nut and the bushing with a locknut. Auger modules are interconnected by an internal sleeve fitting across the tubular ends of each module. One sleeve portion includes a first ring fixed inside the module by welding studs applied through perforations in the auger tube and a second ring is joined to the tube end by a weld seam. The other portion has a second pair of rings with threaded holes to receive bolts passing through the wall of the other auger module.

Dependent claims

A method for assembling an auger module collinearly with another auger module to extend the length of an auger device in a harvesting header, with a sleeve made with a first portion having a cylindrical surface sized to fit tightly inside a tubular end of the first auger module and a second cylindrical portion of smaller diameter than the second auger module around which at least two rings are fixed, sized to fit tightly inside a tubular end of the second auger module, both auger modules comprising a series of spiral flights affixed to a tubular or cylindrical body;

said method comprising the steps of:
(a) inserting the first cylindrical portion of the sleeve into the tubular end of the first auger module, leaving a second cylindrical portion of the sleeve protruding outside said first sleeve portion;
(b) aligning the sleeve with the first auger module;
(c) firmly affixing the aligned sleeve inside the first auger module
(d) fitting the tubular end of the second auger module onto said rings of the second cylindrical portion of the sleeve that projects outside the first sleeve portion;
and
(e) firmly affixing the second auger module around the sleeve.

4 more elements

An auger device comprising:

a first auger module and at least a second auger module, each auger module comprising:
a tubular or cylindrical body having an end portion each joined to the end portion of the other auger module;
spiral flights affixed about said body of each of said auger modules;
and
a sleeve comprising a cylindrical or tubular body whose external diameter is smaller than the internal diameter of the auger body so as to fit inside said auger body, said sleeve having a first sleeve portion affixed inside the first auger module and a remaining second sleeve portion affixed inside the second auger module, whereby said sleeve rigidly joins said bodies of the auger modules to one another;
wherein the sleeve further comprises:
a first pair of centering rings on the first portion and a second pair of centering rings on said second portion of the sleeve, both pairs fitted to the difference between the internal diameter of the tubular device and the external diameter of the cylinder or tube;
at least one of the rings of the second portion having holes provided in its cylindrical lateral face configured for receiving fastening elements;
the first auger module having at least one series of through-holes distributed around the cylindrical periphery of its tubular or cylindrical body corresponding to at least one of the centering rings of the first portion of the sleeve for applying first fastening elements of the sleeve to the first auger module;
and
the second auger module having at least a series of holes distributed around the cylindrical periphery of the tubular or cylindrical body of the auger device corresponding to one of the rings of the second pair of rings of the sleeve to which second fastening elements are applied to retain the second auger module on the second sleeve portion.
