Abstract
The present invention relates to a self propelled track mounted paddy harvester (1) that is driven in any kind of soil condition for harvesting, threshing and cleaning the crops grown in paddy fields. Said harvester (1) is equipped with rubber track system (5) that comprises an endless‐crawler belt (5e) extends over the sprocket (5c) and the idler tumbler (5d) and a plurality of rollers (5f). Said endless‐crawler belt (5e) is made of a plurality of metal links or shoes pivotally attached to each other by providing a rubber cover on said metal links. Such configuration of harvester (1) ensures the low ground pressure thereby said harvester is moved in the muddy terrain for performing harvesting, threshing, cleaning and discharging the grains from the crop.
Claims
1. A self-propelled track mounted paddy harvester (1) that comprises a main frame (2), hydraulic transmission system (3) located at rear side of the main frame (2), a crop harvesting apparatus or header (4) located at front side of the main frame (2) and a rubber track system (5) located beneath the main frame (2); wherein said main frame (2) comprises a operator platform (21) with canopy (21a) and operator's bed (21b), a grain tank (22) located rear to the operator platform (21), a swing discharge auger (23) for discharging harvested grain introduced in the grain tank (22), an axial flow threshing and separating unit (24) wherein threshing, separating and cleaning process of harvested crops take place and a crop conveyer (25); wherein said threshing and separating unit (24) consists of a rotor housing (24a), a rotor element (24b) which is arranged rotatably driven inside of the rotor housing (24c), a cleaning system (24c) having an upper sieve located below the rotor housing (24a) and a lower sieve positioned below the upper sieve in a stacked relationship therewith, a bottom grain auger (24d) which is arranged in some distance towards the sieve means (cleaning system) (24c) for collecting and transporting clean grains from the lower sieve to the grain collecting tank (22), a coercive sieve for receiving unthreshed
grain from the lower sieve and a grain conveyer auger for conveying said unthreshed grain to the rotor housing for re-threshing process; wherein said crop harvesting apparatus (4) comprises a reel (43) with tines (45) supported on reel arms (46) sweeps standing or sleeping crop material rearwardly, a cutterbar (41) which severs the crops and a screw conveyer (42) for consolidating and conveying severed crop towards the crop conveyer (25); wherein said hydraulic transmission system (3) comprises an engine
(3a), an oil cooler (3b) for providing cooling to oil circulated from said engine (3a), an auxiliary hydraulic pump (3c) and a tandem hydraulic pump (3d), said auxiliary hydraulic pump (3c) and the tandem hydraulic pump (3d) are driven by the engine (3a); wherein said rubber track system (5) mainly comprises a support frame (5a) and a pair of tracks (5b); wherein said track (5b) comprises a sprocket (5c) having plurality of teeth on outer peripheral thereof, an idler tumbler (5d), an endless rubber-crawler belt (5e) having slots (5e') embedded in inner surface thereof and aligned in the longitudinal direction thereof for receiving teeth of the sprocket (5c), said endless-crawler (5e) extends over the sprocket (5c) and the idler tumbler (5d) and a plurality of guide rollers (5g) disposed interiorly of and in contact with the crawler belt (5e) between the sprocket (5c) and the idler tumbler (5d)
21
and which roll along the internal periphery of the crawler belt (5e), a plurality of lugs (5e") are formed on and extended perpendicularly or angled from the outer surface of the crawler belt and a spring means (not shown) for controlling track tension and absorbing shocks during operation of the machine (1); wherein said rubber- crawler belts (5e) are made of a plurality of metal plates pivotally attached to each other by providing a rubber cover thereon that ensure low ground pressure at 25 Kg/ sq cm; wherein said tracks (5b) are propelled by the tandem pump (3d); wherein width of each track (5b) is kept 500mm.
2. The self-propelled track mounted paddy harvester as claimed in claim 1, wherein said operator platform (21) is equipped with the hydraulic transmission levers (21c) being operated by the tandem pump (3d) for controlling the forward, reverse and turning motion of the machine (1), tower control lever (21d) being operated by the auxiliary hydraulic pump (3c) for controlling the lowering and lifting movement of the cutterbar (41) and the reel (43).
3. The self-propelled track mounted paddy harvester as claimed in claim 1, wherein said operator platform (21) is equipped with at least three clutch levers for performing harvesting, threshing and
23
separating, cleaning and discharging operation of the grain simultaneously.
The self-propelled track mounted paddy harvester as claimed in claim 1, wherein said operator platform (21) is equipped with a safety indication in form of warning lights for the engine oil temperature and level for engine and meters for monitoring oil pressure, engine temperature and fuel gauge on the operator platform.

STATEMENT UNDER ARTICLE 19 (1 )
The claims 1-5 of present invention are considered as novel as no single document discloses all features of the present invention (Please refer box No. 5, Para 2 of written opinion of the international search report). However, the inventive step of claim 1 is alleged to be obvious for a person skilled in the art by having the knowledge Dl and D2. Against this objection, it is respectfully submitted that Dl discloses a rice combine harvester having a track type configuration for propelling in the muddy land. D2 relates to a rubber pad being utilized in track so that propelling can be improved by using rubber track. However, the present invention teaches to improve the self propelling system of paddy harvester by defining the optimum width of the track. According to amended claim 1, the width of the track is preferably kept at 500mm. However, neither of given cited prior art teaches about the optimum width of the track. Further, due to having width of 500mm of each track, it generates low ground pressure around 25 g/sq cm so that the machine (1) can be propelled in the wet land easily [Please refer original claim 5 and Line No.: 16 to 18 of page No.: 12 of complete specification].
From the reason spelt out above, it is seen that neither of given prior arts disclose, teach or suggest regarding the optimum width of 500mm of the rubber track. Further, said optimum width of the tracks generates low pressure ground that helps the harvester to easily propel in the muddy field. Hence, the person skilled in the art can not conceive the present invention by having knowledge of prior arts. Thus, the amended claim 1
25 of the present invention can not be considered as obvious and therefore present invention is inventive.
