8.1 SELF-PROPELLED VERTICAL CONVEYOR REAPER

Features:

 

It is an engine operated, walk behind type harvester suitable for harvesting and windrowing cereals and oilseed crops. The reaper consists of engine, power transmission box, pneumatic wheels, cutter bar, crop row dividers, conveyor belts with lugs, star wheels, operating controls and a sturdy frame. The engine power is transmitted to cutter bar and conveyor belts through belt pulleys. During forward motion of the reaper, crop row dividers divide the crop, which come in contact with cutter bar, where shearing of crop stems takes place. The cut crop is conveyed to one side of the machine by the conveyor belt fitted with lugs and is windrowed in the field. The crop is bundled manually and transported to threshing yard. There are no shattering losses due to vertical conveying of the crop.

8.7 SUGARCANE HARVESTER

Features:

It is a chopper harvester with a cleaning system and whole cane harvesters are also available. 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 and simultaneously de-topped from top. 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. The can 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.

8.9 STRAW REAPER/STRAW COMBINE

Straw Combine Harvester

Features:

 

Straw combine operated by tractor PTO 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.
