Abstract

A mechanical arrangement introduced into a grain collecting and processing machine using a hinged traction bar is provided, wherein two swivel gearboxes are installed, allowing the head to be assembled in the center and the machine to work laterally displaced over the tractor vehicle, on both sides, thus facilitating both the operation and the collection process. A grain collecting and processing machine including the mechanical arrangement is also provided.

Claims (37)

1 . A mechanical arrangement introduced into a grain collecting and processing machine comprising:

(a) a traction bar, having two opposite sides; a front section and a rear section;

(b) multiple beater drums;

(d) a screen set, having a front crosswise shaft including an eccentric shaft located at a central section;

(e) multiple fans; and

(f) multiple choppers;

wherein the traction bar is hinged on the two opposite sides, and comprising:

a first and a second swivel gearboxes, the first swivel gearbox installed on the front section of the traction bar, after a cardan shaft coupling to a power outlet of a tractor, and the second swivel gearbox installed on the rear section of the traction bar;

a third intermediate gearbox is installed between the first and the second swivel gearboxes, the intermediate gearbox controlling a rotation transmitted by a fourth central gearbox, located adjacent to the second swivel gearbox installed on the rear section of the traction bar to a fifth gearbox activating the beater drums.

2 . The mechanical arrangement of claim 1 , wherein the rotation control transmitted to the fifth gearbox activating the beater drums may be optionally performed by the fourth central gearbox, located adjacent to the second swivel gearbox installed on the rear section of the traction bar.

3 . The mechanical arrangement of claim 1 , further comprising a first gearing, located on a shaft of one of the beater drums, having a chain, transmitting rotation to a second gearing of a sixth gearbox; the sixth gearing transmitting rotation to a first pulley; a belt actuated by the first pulley activates a second pulley; the second pulley activating the admission roller.

4 . The mechanical arrangement of claim 1 , further comprising a third pulley, located on the second opposite edge of the admission roller, a belt actuated by the third pulley, activates a fourth pulley of a front crosswise shaft of the screen set.

5 . A grain collecting and processing machine comprising the mechanical arrangement of claim 1 .

6 . A mechanical arrangement introduced into a grain collecting and processing machine comprising:

(a) a traction bar, having two opposite sides; a front section and a rear section;

(b) multiple beater drums;

(d) a screen set having a front crosswise shaft including an eccentric shaft located at a central section;

(e) multiple fans; and

(f) multiple choppers;

wherein the eccentric shaft synchronizes an alternated linear movement of the screens, neutralizing vibrations caused by the displacement of the screens.

7 . The mechanical arrangement of claim 6 , further comprising a first pulley set, located on the rear section of the beater drums; a first set of belts, actuated by a second pulley set of the multiple fans.

8 . A grain collecting and processing machine comprising the mechanical arrangement of claim 6 .

9 . A mechanical arrangement introduced into a grain collecting and processing machine comprising:

(a) a traction bar, having two opposite sides; a front section and a rear section;

(b) multiple beater drums;

(d) a screen set having a front crosswise shaft including an eccentric shaft located at a central section;

(e) multiple fans; and

(f) multiple choppers assembled horizontally;

wherein the multiple fans further comprise a front third pulley set, actuating a second set of belts;

wherein the second set of belts actuates a front fourth pulley set of a double pulley arrangement;

wherein a third set of belts actuated by a rear fifth pulley set actuates a sixth pulley set of gearboxes;

wherein the sixth pulley set transmits rotation to a seventh pulley set, and

wherein a fourth set of belts actuated by the seventh pulley set actuates an eighth pulley set, rotating the horizontally assembled choppers.

10 . A grain collecting and processing machine comprising the mechanical arrangement of claim 9 .
