Abstract

A relatively large part of the cultivated area in Iran is devoted to COTTON production. Due to the problem of residues and the importance of removing COTTON stalks after harvesting, a project was conducted to develop and evaluate a COTTON STALK PULLER. A machine is required to remove COTTON stalks to reduce pest proliferation after harvesting. Use of two cleated diskes placed on a main chasis was selected for stalk pulling after the investigation of different methods. Tilt angle, disk overlap and rake angle were adjustable in the machine. The project was carried out using the following two steps. Firstly, the required characteristics of COTTON field and stalks were determined by performing primary field experiments. The proper estimated values for tilt angle from 25 to 35 degree, rake angle from 17 to 27 degree and disk overlap from 25 to 55 mm were determined using the mentioned characteristics, theoretical calculations and computer software. DESIGN of the machine was consisted of three sections, namely: the way to fix disks and axle mechanism, mechanism for disk connection to chassis and chassis. Chassis of the machine connected to the three-point hitch of the tractor. After completing the prototype construction, machine PERFORMANCE was tested and evaluated in the field. Secondly, the effects of treatments (tilt and rake angles and disk overlap each at 3 levels) on machine efficiency were evaluated with three replications in the field. The experimental DESIGN was split plot in a completely randomized block DESIGN. In the field experiments, soil moisture content and CI were 8% (d.b.) and 1.55 MPa, respectively. The results revealed that tilt angle of 30 degree with PERFORMANCE of 95.4 %, the rake angle of 17 degree with 94.9% and finally disk overlap treatment at an overlap of 25mm with 94.1% were appropriate factors for the best machine PERFORMANCE resulting in maximum percentage of stalks being removed. These technical parameters and specifications can be used in semi-industrial and mass production of the machine.
