DETERMINATION AND ANALYSIS OF FIELD PERFORMANCE OF A DEVELOPED COTTON TRANSPLANTER
SALAH EL-DIN ISMAIL EL-KHATIB;
Abstract
The aims of this study are to develop a transplanter to transplant cotton and to suitable for Egyptian conditions.
The main results in this study can be summarized in the following points :
(I) The value of force required for holding the paper pot should be higher than 43.65 N.
(2) The spring wire was 0.30 em to avoid excessive pressure.
(3) The developed Holland transplanter (which using bare root) has less rolling
resistance due to it is weight lower than Lainnen transplanter.
(4) The value of slippage power for Holland machine is less than Lainnen machine, were
0.05, 0.15 and 0.29 hp and 0.11, 0.27 and 0.44 hp, respectively for one unit but for two unit were 0.26, 0.52 and 0.77 hp and 0.37, 0.74 and 1.10 hp, respectively.
(5) By increasing speed from 0.75 to 1.50 km/hr, drawbar power for developed Holland machine were 2.22 and 4.44 hp. and 2.64, 5.28 hp for Lainnen machine, respectively that for one unit, but for two unit were 3.33 and 6.67 hp for developed Holland machine and 4.03, 8.06 hp for Lainnen machine two units respectively.
(6) When increase forward speed from 0.75 km/hr to 1.50 km/hr the fuel consumption increased from 2.25 to 2.64 lit/hr and from 2.35 to 2.90 lit/hr for developed Holland transplanter and Lainnen transplanter one unit, respectively. Also; it increased from
3.10 to 3.50 lit/hr and from 3.50 to 3.90 lit/hr for developed Holland and Lainnen
transplanter two units, respectively.
(7) The required power for operation were 9.68, 10.32 and 11.35 hp for one unit developed Holland transplanter and 10.10, 10.97 and 12.48 hp for Lainnen transplanter one unit. Also, the required power for operation were 13.34, 14.41 and
15.06 fo•• developed Holland transplanter two units and 15.06,15.70 and 16.78 hp for
Lainnen transplanter two units.
(8) The developed machine lost time was 2.18 hr/fed at forward speed 0.75 km/hr and by increasing the forward speed to 1.15 km/hr the time losses was 1.53 hr/fed. After that by increasing fonvard speed the time losses increased. The time Josses when using Lainuen transplanter were 1.87,1.34 and 1.84 hr/fed at forward speed 0.75, 1.15 and
1.50 km/hr, respectively.
