Definitions
- the present invention relates to a sugarcane harvester and more particularly it relates to a sugarcane harvester with an improved base cutter gearbox assembly.
- sugarcane harvesters are on field which harvest the growing sugarcane stalks by cutting the cane at its base, and then transferring the cut sugarcane to a collector vehicle such as a cane wagon or cane cart.
- the sugarcane harvester may include different types of harvesting devices.
- the harvesting devices for a sugarcane harvester can include assemblies for cutting, chopping, sorting, transporting, and gathering and processing sugarcane plants.
- the harvesting devices include crop divider assembly, knockdown roller assembly, base cutter assembly, feed rollers, cutting drums, and so on.
- a harvester may move along a field with abovementioned harvesting devices, where the harvesting devices perform collecting and processing of material from rows of crop plants.
- the base cutters are constructed to minimize the quantity of earth fed into the harvester with the crop.
- Prior art base cutter gear box at cane harvesters had spur-gears whose surfaces have rolling contact, but the teeth are cut straight across on a face; one or two teeth are always in contact with another gear. This incomplete face engagement means spur gears are noisier and vibrate more than helical gears.
- base cutter gear box is that it causes too much noise and vibration means low precision and limited life.
- Rotating machines that are noisy and vibrate can have any number of quality issues: improperly balanced rotating components; mating components with excessive tolerances; and components that are not rigid enough, flexing under load and leading to misalignment.
- the main object of the present invention is to overcome the problem associated with base cutter gearbox assembly of sugarcane harvester by providing an improved base cutter gear assembly for proper harvesting at fields.
- Another object of the present invention is to provide an improved base cutter gearbox assembly to sustain and alleviates the load on each tooth and creates a smooth transition of forces from one tooth to the next, less vibration, wear, and noise, and longer life.
- Further object of the present invention is to provide an improved base cutter gearbox assembly to allow achieving a high-efficiency gear mesh.
- the present invention relates to a sugarcane harvester and more particularly it relates to a sugarcane harvester with an improved basecutter helical gearbox assembly.
- An improved basecutter helical gearbox assembly has an configuration which is depicted as basecutter unit.
- the input interface is a splined connector, configured to receive the output shaft of the hydraulic motor.
- the input interface is configured such that the rotational power received at the interface by one hydraulic motor causes the pinion gear to rotate.
- the pinion gear in turns rotates the main gear and idler timing gear.
- the idler timing gear then rotates the main gear.
- the said gears used at the base cutter gearbox uses an optimum helix angle designed to sustain and alleviates the load on each tooth and creates a smooth transition of forces from one tooth to the next, hence, less vibration, wear, and noise, and longer life.
- Fig. 1 illustrates a schematic line diagram of a basecutter gearbox assembly for a sugarcane harvester according to the present invention.
- Fig.2 illustrates parts of a base cutter gearbox assembly for a sugarcane harvester according to the present invention.
- a sugarcane harvester is a large piece of agricultural machinery used to harvest and partially process sugarcane. Essentially a storage vessel on a truck with a mechanical extension, the machine cuts the stalks at the base, strips the leaves off, and then cuts the cane into segments. These are then deposited into either the on-board container, or a separate vehicle traveling alongside. Waste material is then ejected back onto the field, where it acts as fertilizer.
- the sugarcane combine harvester having a topper in advance of a crop divider mechanism with the crop divider aiding in moving sugarcane to knock down feed roll, base cutter, a feed roll system, a chopping system, a cleaning arrangement viz. primary extractor and an elevator system including a secondary cleaning arrangement viz. secondary extractor.
- the present invention particularly concern with an improved base cutter assembly.
- said base cutter assembly comprises a base cutter, a helical gearbox assembly connected to the base cutter and a hydraulic motor for driving said helical gearbox assembly.
- Said base cutter comprises a pair of ratable base cutters (7a, 7b) having projecting blades (8a, 8b) to sever sugar cane sticks from their roots.
- the pair of rotatable base cutters (7a, 7b) is directly connect to the said helical gear box assembly through vertical shaft (6a, 6b) due to which the base cutters (7a, 7b) starts rotating to harvest the stalks at the base, strips the leaves off, and then cuts the cane into segments.
- Said gearbox assembly comprises a main gear (1) and (4) having plurality of serrations on outer periphery thereof; a pinion gear (2) having plurality of serrations on outer periphery thereof and mesh with the serration of the main gear (1); an idler timing gear (3) that accommodate a splined connector having plurality of serrations on outer periphery and mesh with the serration of the pinion gear (2) and main gear (4).
- the said main gears (1, 4), the pinion gear (2) and the idler timing gear (3) having an optimum helix angled tooth designed to sustain and alleviates load on each tooth and creates smooth transition of forces from one tooth to the next resulting less vibration, wear, noise and longer life.
- Tooth profiles of the gears are very precise.
- the units are packaged in sealed. Oil- filled housing requires no oil changes.
- Said base cutters (7a, 7b) are connected to the main gear (1, 4) through the vertical shaft (6a, 6b) respectively.
- the pinion gear (2) is driven by the motor (5) through the splined connector being connected to the shaft of the motor (5).
- the input interacts with the splined connector, configured to receive the output shaft of the hydraulic motor (5).
- the input interface is configured such that the rotational power received at the interface with help of hydraulic motor (5) due to which the pinion gear (2) starts rotating.
- the pinion gear (2) in turns rotates the main gear (1) and idler timing gear (3) due to which the main gear (4) starts rotating.
- the said helical gear box is positioned above the base cutters (7a, 7b) within the throat of the harvester.
- the base cutters (7a, 7b) are positioned between the harvester's front wheel so that the cutting height is unaffected by pitching of the harvester when traversing uneven terrain.
