HARVESTING EQUIPMENT
8.1 CHOPPER |
|
Features:
Chopper is a simple harvesting hand tool, which consists of a blade,
tang and a handle. The cutting edge is slightly curved (convex)
along the cutting edge to facilitate the cutting. The blade is
joined to the handle by inserting its tang. The blade is forged to
knife section and cutting edge sharpened. The blade is important
part of the tool and is made from medium carbon steel, high carbon
steel, manganese steel or alloy steel including tool steel. The
cutting edge is hardened and tempered to suitable hardness to resist
wear and abrasion. The tool made from tool steel and alloy steel has
more service life as compared to the plain carbon steel blade. The
blade should have property of toughness to resist the impact
stresses. The handle is made of wood and shaped to suitable
handgrip. For operation, the blade is struck hard against the stem
with one hand and the cutting is accomplished by the impact action
and sliding of the blade along the stem. The shape and size of the
chopper varies from place to place and its use. |

8.3 BHENDI PLUCKER |
|
|
Features:
The tool is ergonomically designed. The plucker consists of two
arms hinged together, cutting blades joined to open ends of arms
and two rings joined to the arms. The blades are made of medium
carbon steel or low alloy steel, hardened and tempered to suitable
hardness. Panicles are cut individually using this tool. The
operator is spared of drudgery, discomfort and itching to skin of
his hands, which are associated with conventional method of manual
plucking without any aid. It fits in to the hand properly with the
help of two rings, one over thumb and another over index finger.
Force to cut the penicle is exerted by pressing these two fingers
against each other. Penicle is sheared between two straight
blades, one of which is notched for better grip. |

8.4 RUBBER TAPPING AND DRAINING KNIFE
|
|
Features:
The
tool consists of a V-shaped, front edged blade, fixed to a wooden
handle with the help of tang and ferrule. The blade is made from
high carbon steel, tool steel or alloy steel. The cutting edge is
heat treated and hardened to a suitable hardness. The ferrule is
made of mild steel and chrome plated to avoid oxidation. For
tapping of the rubber fluid from the rubber trees, the V -shaped
front edge, which is a cutting edge, is used to inflict a cut a
groove on the tree trunk through which the rubber fluid slowly
flows out. The groove acts like a channel and opens the latex
cells and thus allows tapping and draining of the latex. A tin is
placed at the end of groove or channel for the collection of the
tapped fluid latex. Formation of the groove is due to the
scratching and shearing action of the tool head. The blade is made
from carbon steel and is heat-treated to obtain a hardness of
30-45 HRC. |

8.6 TAPIOCA HARVESTER |
|
Features:
The tapioca harvester consists of a mainframe with three-point
hitch system, shank with depth adjustment and digging blade with
pegs. It has provision for adding dead weight on the main frame
for penetration of blade in hard soils. The shank is made up of
mild steel and the digger blade is attached to it. Provision has
been made for changing the depth of digging, according to the
tube geometry and moisture condition of the soil. The digging
blade is trapezoidal in shape and is made of 13mm thick mild
steel plate. Five pegs are provided at the front end of
trapezoidal digging blade for easy penetration into the soil and
reduce the draft requirement of the unit. Before digging
operation, the base cutting and removal of the plant is carried
out.
