In India, cotton is still picked manually by ladies pickers. Shortage of
labor availability for cotton picking on farms results delayed picking of cotton crop and
loss in term of cotton production. Commercially available cotton harvesters were tried
for Indian varieties, but there were some issues regarding the cotton harvesting.
Knowing the conditions of Indian farms, a conceptual design of self-propelled finger
type cotton stripper is generated to pick/harvest the local high density and dwarf cotton
varieties mechanically. In this self propelled finger type cotton stripper, the stripping
fingers of 70 cm length were welded to the front part of engine frame at an angle of 21º.
The width of the developed head was 64 cm. A rotating paddle/kicker, having a speed in
the range of 120-250 min-1, was designed to push the stripped materials (cotton bolls i.e.
opened and closed along with sticks and burs) in to the collecting tank. A collecting
drum/tank, having capacity 15-20 kg, was attached just behind the cotton stripper head
for collecting stripped cotton materials. The developed prototype was evaluated on F-
2383 and RCH-773 cotton varieties to observe its performance. The average value
picking efficiency and picking capacity of developed cotton stripper was observed to be
in the range of 76-80% and 135-325 kg·hr-1, respectively. The observed value of seedcotton
was observed in the range of 74-80% by using boll crusher/seed-cotton extractor,
operational at Bathinda in Punjab. U Indiji se još uvek pamuk bere ručno. Nedostatak radne snage dovodi do
odloženog branja i gubitaka u proizvodnji. Berači koji su dostupni na tržištu su probani
sa indijskim sortama, ali bilo je problema. Poznajući uslove na farmama u Indiji,
razvijen je berač sa prstima na ručni pogon za branje domaćih sorti pamuka. Kod ove
konstrukcije prsti dužine 70 cm su zavareni na prednji deo rama mašine pod uglom od
21º. Širina glave je 64 cm. Rotacione pedale rotiraju sa 120-250 min-1 i guraju ubranu
masu (čaure sa peteljkama) u sabirni sanduk kapaciteta 15-20 kg. Sanduk je postavljen
odmah iza glave berača. Ovaj prototip je testiran na sortama F-2383 i RCH-773. Srednja
efikasnost i kapacitet branja iznosili su 76-80% i 135-325 kg∙hr-1, redom. Istresanje
semena je iznosilo 74-80% primenom drobilice čaura.
