An Automated Sickle
Project Description :

An automated version of motorized ‘sickle’ has been made operational with variants to suit the requirement of harvesting in the fields as well as ‘chopping’ to yield variety of chopped grass, mustard, sand grass and doob grass, with the purpose of preparing ‘ready to eat’ fodder for animals. the utilization of automated ‘sickle’ and its variants shall give advantage to avoid leftover stubs of a crop in the field after completion of harvesting, particularly because its function of cutting of a plant right at the soil surface could be easily achieved. poor farmers in most of the northern and central parts of the country employ agricultural practices on smaller land holdings. they are constrained to deploy heavier machines mounted on mechanized vehicles because of finance crunch. similar difficulty is encountered at the hilly terrains of the himalayas, and other places because of agricultural fields being established on slopes. the unit comprised twin blades, one of which is fixed while the frequency and bi-directional, back and forth, movement of the other one is regulated by a battery-powered motor, that could also be operated electrically. thus the speed of the blade varied to the factor of stiffness of crop plants i.e. rapid while chopping sugarcane, sudan grass, lantana weed but slower pace to chop crops like paddy, wheat etc. the sharpening stone along the edge of the blade fixed in the device shall be the automated sharpening device. a fibre guard is at the bottom of blade (when device is vertically held in operation) to avoid any accidental hit of blade on the body of operator of the machine. there are three variants of the automated sickle:- 1. sickle routine : a conventional sickle comprising curved blades with two sub-variants- a. with plain blades- used to cut plants having herbaceous and soft stems e.g. clover. b. with toothed blades- used to cut crop at the harvesting site, when the crop is ripe to be harvested but stem still green e.g. paddy, wheat that retained moisture at this stage. 2. twin twisted blade: a elongated twin twisted blade attached with a heavy speed battery operated motor would allow the user a handy operation of various requirements of harvesting in the field. this design would facilate operation at the required speed harvrvesting at aparticular angle for better and faster result. to harvest the plant crops its round and twisted blades in circular motion would. 3. wall mounted chopper: a modified wall-mounted toothed blade sickle, with its blade pivoted on an accessory component for fodder preparation. the chopped ‘ready to eat’ feed is the output by the semi-circular chopping action of the sickle to cut crop parts inserted through accessory component. advantages in harvesting automated sickle will take lesser time and manual effort in harvesting of crops. it can be employed easily anywhere irrespective of the terrain and size of land holdings unlike combines and harvesters that require plain terrain and larger land holdings for their feasible deployment. 1. automated sickle would take lesser time and effort due to being motorized. 2. the variable speed of movement and changeable blades make it easier to use for chopping crop variety and weeds in context of stem stiffness. 3. the self-sharpening of blades would save the trouble of keeping an eye on the functioning of blades and save time. 4. in view of the chopping of crop tops only to collect ‘ear’ of wheat/corn or other graminiferous parts by the conventional vehicle-mounted mechanized machines, this device would be advantageous to leave no stubs behind in the crop field. therefore any human effort to burn stubs to create havoc in terms of air pollution shall be avoided. 5. the automated sickle is a handy, portable accessory for the farmers as it required no expertise or specialized training to operate. it is user friendly.
