摘要：
Clearing the land from bushy plants and noxious weeds by human labour is not only higher cost but the noxious weeds causes allergy to human labour due to physical contact. Presently available bush cutter engine and flail mowers are being imported for local use hence the users have to incur higher investment cost apart from higher operational cost. So to avoid these problems an indigenous technology with the multi-purpose machine for rototilling and bush cutting was developed. The present invention is the multipurpose machine which includes main frame, multi speed gear box, chain drive transmission unit, rotary assembly unit and depth control wheel assembly. The multi speed gear box comprises of gear shifting lever, bevel gears and spur gears with inner splines, inner shaft and outer shaft with outer splines, heavy duty roller bearings. The purpose of combined unit with the gear shifting lever in the multispeed gear box is to alter the standard PTO speed 540 rpm from either to 230 rpm or 1600 rpm depending upon the operations.Rotary assembly unit was developed and mounted below the main frame which consists of hollow circular shaft, flanges, chain flails and circular blades. By providing a novel mounting assembly for a free swinging chain type flails welded with the circular bladesand threaded between the flanges of the machine and are spaced along and around the circumference of the hollow shaft. Each of the chain flails includes a plurality of interconnected cable chain links that are looped together to form the flexible chain fail. Chain flails with circular blades are spaced apart pattern along the length of the hollow circular shaft and circular blades having vegetation cutting portions being and arranged to overlap each other, and thereby effect of complete cutting for the entire length of the hollow circular shaft.To maintain the gap between the soil and blade, a depth control wheel assembly was fabricated and fitted at both sides of the machine by means of bo
