The article presents research results of a corn harvester
device for corn cobs separation from the stalks,
constructed as a separate picker. Each picker unit
consists of three pairs of flat conveying belts arranged
in parallel to vertical planes, namely an upper pair of
conveying belts, the lower pair of conveying belts and
fixed to corn harvester sweep frame, kinematically is
not connected to other mechanisms and is provided
with electric power with the possibility of adjusting
the width of the aisle and the rapid replacement of the
failed module with a spare unit in the field repairs.
Picker module provides simultaneous rotation of corn
ear on its axis and motion relative to the stem that
reduces corn cobs defect and energy consumption for
separating cob from stalk. The method of calculation
of the basic design parameters of the picker module is
developed
The article demonstrates a possibility of creation of a
corn harvester with a sweep frame mounted from
individual modules. Such corn harvesters include
modules for cutting stalks, snapping modules,
conveyor modules for turning, stacking and feeding
the stalks in the shredding unit, conveyor modules for
supplying corncobs to the cleaning device placed on
the sweep frame, leading and managing bridges,
power unit, as well as conveyor belt for cobs and
auger for discharging the crushed plant matter. The
technique for calculating the grinding module drive
was shown. The arrangement of the modules on the
corn harvester sweep frame was demonstrated. Corn
harvesting with the suggested module corn harvester
allows not only reducing combine metal consumption
and reducing corn ears injuring, but improving
maintainability as well
The article presents results of design development and
calculation methodology for corn harvesters stalks
shearing mechanism constructed as a module with a
storage device. According to the number of
engagement rows, these modules are mounted on the
sweep frame of corn harvesters. All modules have the
ability to accumulate energy, the rotation of saws in
which at each time point does not depend on saws
rotation in other modules and they are not connected
with each other and with other mechanisms.
Constructive execution of corn stalks shearing
mechanism with accumulation device allows rapid
separation of each module from the frame of the corn
harvester in order to eliminate possible problems
(change of saw or the entire module assembly). The
methods of the energy storage calculation and electric
motor power selection for each module are presented
