ABSTRACT

ABSTRACT: This experiment was carried out in the workshop of the Department of Agric. Eng., Faculty of Agriculture, University of Khartoum during the period (November 2012- April 2013). Ripen heads of sunflower were put in six paper sacks 300 g in each sack to be threshed with this thresher. The concave of the thresher was adjusted by using different number of teeth in each row. Three teeth for every row were used for the first treatment, and two teeth for the second treatment for threshing 300 g of the heads. The parameters measured were: time of operation, fuel consumption, percentage of straw, material capacity and cleaning efficiency. When three teeth were used for the concave rows the time of operation, fuel consumption, percentage of straw, material capacity and cleaning efficiency were 2.93 minutes, 148.33 ml, 0.74%, 6.143kg/h and 99.26% respectively. When two teeth were used for the concave rows the time of operation, fuel consumption, percentage of straw, material capacity and cleaning efficiency were 1.14 minutes, 46.67 ml, 5.86%, 15.789 kg/h and 95.9% respectively. From these results it can be concluded that this thresher is capable of threshing the heads of sunflower crop when adjusting the concave by using three teeth in each row, as it gives more cleaning efficiency and less amount of straw.

[1]. Number of teeth in each row in the concave has effect on the time of finishing the operation of threshing. Using two teeth the thresher spends less time than using three teeth.
[2]. There is no significant difference in consumption of fuel for 2 and 3 teeth concave.
[3]. The two teeth concave recorded high values for percentage of straw in the threshed seeds. There is a high significant difference between two teeth and three teeth concave.
[4]. Using the three teeth concave gives more cleaning efficiency.
[5]. The three teeth concave made less material capacity.
