Abstract

A sugar cane leaf remover machine comprises a self propelled motorized frame forming a tunnel in which the standing stalks of sugarcane pass through because of the forward movement of such frame. A couple of side arms attached to the front of the frame raise lodged sugarcanes and align straight and lodged sugarcanes to the front end of the tunnel machine. A movable arm protruding forward ahead of the tunnel on which is mounted a cutting device to remove the top leaves of the sugar cane. An adjustable deflector (tunnel ceiling board) to engage and bend the standing sugarcanes at an angle suitable for the removal of the leaves.A set of rotary brushes, disposed on the side of the machine with an angle such as the brushes to be near perpendicular to the canes bent by the deflector. The machine above moves along therow of sugarcane stalks planted, not cut, forcing the sugarcane to bend and pass in a tilt forward position through a tunnel formed by counter rotating brush of a cylindrical shape. Through the passage in the tunnel the cylindrical brushes are removing the leaves along the stalk. The longitudinal axys of the cylindrical brushes is inclined in a way to be near perpendicular to the tilted forward stalks. The stalks are maintained bent forward during the passage in the tunnel by an adjustable ceiling board above the top end of of the stalk. After the stalks have passed through the tunnel, they exit from the end of the tunnel and they regain their original position. They are then ready to be harvested by any conventional mean (mechanical or manual), with the advantage of being free of leaves and still attached to the ratoon.

SUGARCANE LEAVES REMOVER METHODS AND APPARATUS
BACKGROUND OF THE INVENTION
1. Field of the invention
The present invention relates to a machine capable to remove leaves from sugarcane stalks still planted as found in a sugar cane field, planted in row and not yet cut. 2. Description of existing method of mechanical and manual sugarcane harvesting and leaves removing:
In order to harvest sugar cane three methods are commonly adopted.
A. Sugarcanes are cut green one by one by hand and knife and the leaves along the stalks are removed using the knife. The upper part of the cane, all made up of leaves, is also removed by knife. The canes so cut are then collected in bundles for loading on transport mean and taken to the sugar mill.
B. Sugarcanes are burnt and successively cut by hand and knife. The top of the cane still must be removed by knife because it does not burn. Burning the cane is practical but the disadvantage is that then canes are loosing a part of their sugar content, plus sugar mills are applying penalties for canes delivered burnt and the burning process is polluting the air with C02 emission.
C. Sugarcane are harvested mechanically, with self propelled machines which in a single passage through the planted canes raise and align the canes, remove the top leaves, bend the canes and cut them at the base, then feed the canes in a chopper that cut the canes in billett and extract dirt and leaves with powerful fans. Canes billett are then discharged into a bin trailed along the mechanical harvester by another tractor/truck. This is the most efficient method, but requires extremely high powerful engines.
SUMMARY OF THE INVENTION
The object of the present invention is a man driven self powered machines able to remove leaves along the stalks and on the top of the cane with the cane still standing using a low power engine, and being able to work across the rows without having the adjacent row to be cut first. This enable this machine to remove leaves in an entire fields planted with sugarcane and cutting the canes in a subsequent stage. Advantages are that for manual harvesting there is no need to remove the leaves by knife or fire; and for mechanized harvesting (using fully automatic machines) there will be substantial saving in fuel consumption and the harvesting machines will be able to travel faster, since the fan leaves extractors are using a substantial part of the power of the engines.
BRIEF DESCRIPTION OF THE DRAWING
Fig 1 is a general side view of the machine in accordance with the present invention
Fig 2 is a perspective view of the machine
Fig 3 is a front view of the machine, clearing showing the "tunnel" through which sugar canes have to pass through.
Fig 4 is a perspective view that shows how the canes are bent and engaged before being stripped of the leaves
DESCRIPTION OF THE PREFERRED EMBODIMENT
Fig. 1-2-3-4 illustrates a machine for removing the leaves of the sugar canes with the said canes still planted on the soil, and after the process of removing the leaves, the said canes are still planted to the soil and returning to the previous position before the passage of the machine. The machine is made of a frame on which are installed an engine (C), a pair of arm (D) with rolling screw (commonly called crop divider) to raise lodged canes, a protruding frame (A) , adjustable in height on which is mounted a rotating cutting mechanism (B) to remove the upper portion of the leaves of the canes, 2 pair of rotating brushes (F - F) inclined, forming a tunnel in which the canes pass through, a tunnel ceiling (E) adjustable in heightwith guides disposed beside each other to form rails, disposed parallel to the advance sense of the machines, designed to maintain the same lateral position of the upper part of the stalk during the passage in the tunnel. The canes travel between two set of rails in which they enters randomly at the moment of entering the tunnel. The moving parts are the rotating brush (F - F) the cutting device (B) the wheels (W), the crop divider (D). The parts which are changing position to accommodate the canes in different heights and position are: the crop divider (D) which can be raised or lower to follow the contour of the soil, the cutting mechanism on the protruding frame (A-B), which moves higher or lower according to the height of the canes, the tunnel ceiling (E) moving up or down to change the bending angles of the canes, by mean of the adjusting screw (V). The movement is transmitted from the engine to the moving parts buy mean of belt (in this drawing), chains, or hydraulic transmission, or electric motors and actuators.
HOW IT WORKS
The machine moves along the canes planted in rows, in the Fig 1 from right to left. The canes, if lodged, are raised by the crop dividers (D) and maintained vertical or near vertical. The adjustable cutting device (A - B) removes the upper part of the canes, made of leaves only. After this process the canes are found as in Fig 1 and 4 (H). The machines keeps on advancing and the cane is engaged under the tunnel ceiling (E) which is adjusted at a height lower than the height of the cane, therefore forcing the cane to bend forward and getting engaged between the rails. The canes now are as in Fig 1-4 (I). The cane must now pass through the tunnel formed by the rotating brush (F-F) and the leaves are removed as effect of the friction produced by the rotating brush on the cane. (Fig 1-4 L). The canes arenow completely cleaned of the leaves and are sliding toward the end of the tunnel, still engaged and bended (Fig 1 M). The cane is exiting the tunnel and regain the original position , same as before the passage of the machine (Fig 1 N) . For the all duration of the passage of the cane in the tunnel (Fig 1 I-L-M) the cane is maintained in a bend forward position due to the low position of the ceiling, which presses the canes down and for effect of the movement of the entire machine forward, resulting in a bend forward position.
