Abstract

The main purpose of this research is to development and evaluates a small threshing machine to suit small spaces spread in Egypt. The threshing apparatus produced at the Tanta Engine Factory (Imagro) was developed, and its effectiveness was assessed at the Itay Al-Baroud Agricultural Research Station 2020 according to two separate experiments the studied crop. The developed machine was evaluated at four levels of drum speed (350, 400, 450 and 500 rpm with faba bean - 600, 650, 700 and 750 rpm with Wheat) and three levels of feeding rate (360, 480 and 720kg/h). The Evaluation was based on the following parameters: productivity, threshing efficiency, threshing damage, cleaning efficiency, blown seed ‎percentage, ‎power requirements, energy consumption and costs. The results showed that increasing the drum speed improved cleaning effectiveness. under both crops and all feeding rates due to the increased rotational speed of the dust exhaust fan. The percentage of blown seeds also increased from 1.07% to 1.73% by increasing the speed of the cylinder from 350 to 500 rpm for the Faba bean crop, at a feeding rate of 720 kg / h. Consumed energy increased with the increase in moisture content, and knife speed. The results also indicated that a decreasing in the costs (LE/Mg) Productivity increased by increasing the feed rate.
