synopsis
The load in digging out the soil has been kept to the minimum by providing appropriate profiles and curvature to the implements through a process of trial and error. Suitable slots are provided for attachments so that the distance between the blades can be adjustable to suit specific requirements. Safety provisions are incorporated so that the blade did not injure the farmer at the time of reversing the device during weeding. Bicycle weeder is a multipurpose farm implement developed by using inexpensive bicycle components. The main part of the implement consists of the front portion of a bicycle, namely handle bar, front axle and the wheel. A steel fork is connected to the axle and other end carries different attachments. Separate attachments for weeding and tilling are attached to the working end using bolts and nuts. This helps in changing the attachments as needed. Manual weeding requires huge labour force and it is time consuming process. The labour requirement for weeding depends on weed flora, weed intensity, time of weeding, and soil moisture at the time of weeding and efficiency of worker. Often several weeding operation are necessary to keep the crop weed free.
DISADVATAGES OF EXISTING CYCLE WEEDER:
1 .The straight handlebar is not convenient to use, it has to be made more ergonomic.
2. The length of the connecting rod is fixed. This fixed length does not accommodate for the fact that the users can be of different heights, and may wish to increase or decrease their distance from the conical wheels.
3. The inclination of the connecting rod is fixed. The fixed inclination will be convenient only for users of a particular height. Most users may have to operate the cono-weeder from an uncomfortable position.
4. More force is required to operate.
5. It cannot cut the weed properly.
