The seedlings are neatly arranged on the seedling tray of the transplanter. 4.1.2 SoH-bearing seedling type or mat type Type of mechanical rice transplanter designed for handling rice seedlings that were grown with mat. Soil and fertilizers were mixed thoroughly and filled uniformly in seedling boxes when growing the seedlings. 4.2 Engine driven or self-propelled rice transplanter Type of engine driven rice transplanter which makes use of engine to actuate its movement in the puddled field. 4.2.1 Riding type Type of self-propelled rice transplanter that allows operator to ride on the machine during operation (Fig. 1) 3 operator's steering seat wheel seedling tray engine paddle wheel float guide wheel Figure la.

Four-wheel riding type rice transplanter 4.2.2 Walk-behind type Type of self-propelled rice transplanter wherein the operator walks behind the transplanter during operation (Fig. 2). 4 handle engine ~ seedling tray belt and grasping fork pulley transmission transplanting arm paddle wheel float Figure 2. Walk-behind rice transplanter 5 Principle of Operation Rice seedlings grown in the nursery shall be placed on the seedling tray of the rnechanical rice transplanter. As the rice transplanter luoves along the puddled field, the grasping fork of the transplanting arm shall get a preset number of seedlings out of the seedling mat. The transplanting arm shall be actuated by a cam assembly which is connected to the PTO shaft of a tractor. The seedlings shall then be directed into the puddled soil. Afterwards, the transplanting arm shall reset back to its original position for the next stroke. 6 Manufacturing Requirements The mechanical rice transplanter shall consist of seedling tray, transplanting arnlS, grasping forks and float or floatation structure. Spacing between each transplanting arm shall be uniform. jo.l The seedling tray shall be tnade of non-corrosive material (e.g. engineering plastic). 16.2 The float shall be made of non-corrosive material (e.g. engineering plastic) with at least 13 tum (1/2") thickness and with a width of at least 152 mm (6"). 6.3 The transplanting arm shall be made of G. I. steel or better material with at least 10 mm diameter. It shall have a uniform spacing of at least 200 mm. 16.4 The grasping forks shall be made of G.!. plain sheet gauge #24 or better material. 6.5 All bearings shall be sealed to prevent water and dirt from entering it. 6.6 All welded parts shall be in accordance with the criteria set in AW S D1.1 :2000. 5 6.6.1 There shall be no crack on welded area. 6.6.2 There shall be fusion between adjacent layers of weld metal and between weld nletal and base nletal. 6.6.3 All craters shall be filled to provide the specified weld size, except for the ,end of intermittent fillet welds outside of their effective length. 6.6.4 Weld profiles shall be in its acceptable form. 6.6.5 Welded joints shall not be less than 4 mm site fillet weld. 6.6.6 Undercut shall not exceed 2 IIDn for any length of weld. 6.6.7 The handle shall be covered with a non-slip Inaterial (e.g. rubber). 6.6.8 The paddle wheel shall be made of G.!. steel or better material. The wheel depth shall be adjustable. 6.6.9 Guide wheels shall be made of non-corrosive material (e.g. G.!. steel). 6.6.10 Row spacing shall be variable. 7 Performance Requirements 7.1 There shall be a field efficiency of at least 800/0. 7.2 The grasping fork shall pick rice seedlings unifonnly. 7.3 The distance between hills and rows shall be uniform based on the desired setting. 7.4 The percent datnaged hills and percent missing hills shall not exceed 10%. 7.5 The seedlings shall be planted at a uniform depth based on the desired setting. 8 Safety, Workmanship and Finish 8.1 The n1echanical rice transplanter shall be painted and shall have a rust-free finish. 8.2 Sealed type bearings shall be used to prevent entry of foreign materials. 8.3 Chain and sprocket or belt and pulley assenlbly shall be covered. 8.4 All bolts shall confonn with standards for strength application and shall be made of hot-galvanized steel for corrosion resistance. 6
