Problem Statement:

Broking of stalks of the paddy during the threshing process

---

Detail:

Traditionally paddy is threshed by beating followed by winnowing and cleaning by the fan. Paddy stalks are the main source of fodder for the animals in the region and in addition they are the raw materials for paper industries. There was shortage of labour and hence the labour charges were quite high too. These constraints were the basic ones when he planned to make such a machine. To overcome this labour intensive paddy threshing and to conserve the paddy strains, Dilip Sinh developed paddy thresher where the paddy grains and stalks are obtained separately at the end of the threshing process.

• The concept of rubbing the crop in between threshing drum and concave and obtaining the whole stalk of the paddy while threshing is in use. US patent nos. 4185642, 3963032, 4174718, 4821744, 4489735 describe the threshing mechanism for paddy, wheat and similar crops. In all these mechanisms, threshing of the crop is achieved by rubbing of the ear-heads in between the threshing drum and the concave. No whole stalk of the paddy is retained in these threshers and is blown out in the form of chopped material called bhusa (husk).
