8.5 SELF -PROPELLED COMBINE HARVESTER

 

 

 

 

 

 

 

Features:

Various designs of combine harvester having 2 to 6 m long cutter bar are commercially available. The function of a combine harvester is to cut, thresh, winnow and clean grain/seed. It consists of header unit, threshing unit, separation unit, cleaning unit and grain collection unit. The function of the header is to cut and gather the crop and deliver it to the threshing cylinder. The reel pushes the straw back on to the platform while the cutter bar cuts it. The crops are threshed between cylinder and concave due to impact and rubbing action. The threshed material is shaken and tossed back by the straw rack so that the grain moves and falls through the openings in the rack onto the cleaning shoe while the straw is discharged at the rear. The cleaning mechanism consists of two sieves and a fan. The grain is conveyed with a conveyor and collected in a grain tank.

8.6 SUGARCANE HARVESTER

Features:

It is a chopper harvester with a cleaning system. This harvester is used to cut green cane (with leaves). It can cut one/two rows of cane at a time.  The cane is fed between the crop dividers and is cut at the root zone by base cutter blades. The cane is then fed through the roller train and is cut by the chopper drums into small cane pieces of 24.5 to 30 cm. It is then cleaned in the primary extractor before being conveyed on the elevator. It is then cleaned again with the secondary extractor and loaded onto a vehicle for transportation. In ideal conditions, the harvester can cut nearly 400 tonnes of sugarcane per day.

DSC057498.9 STRAW REAPER/STRAW COMBINE

 

 

 

 

 

 

Features:

Straw combine is pulled by tractor and operated by tractor PTO. It has cutter bar reel, feeding auger and bruising cylinder like a traditional thresher. Straw thrown and stubble left by the grain combine is collected by straw combine and delivered to the cylinder concave section, where it is cut into pieces and passed through the concave. A reciprocating cutter bar is used for reaping the standing stubbles and the portion of the straw left uncut by the combine harvester. Straw, which passes through the concave, is aspirated by a blower and fed into a trolley on rear side covered by a wire net. For recovering the left grains from the straw, a sieve system is provided below the concave.

stuble shaver8.10 SHRUB MASTER

 

 

 

 

 

Features:

It consists of cutting blades (swinging flails) fixed to the rotating bar, gear box for transmission of power at right angle, universal joints with telescopic shaft to connect the tractor PTO and gearbox, adjustable side skids for controlling cutting height of shrubs or grass, safety guard and hitching frame. It is operated by tractor PTO. The bar having cutting blades fixed at the ends is mounted on the gearbox shaft. Thus, the vertical shaft of the gearbox provides rotary motion to the bar.
