Description:FIELD OF THE DISCLOSURE
The present disclosure generally relates to husking foodgrains. More specifically, the present disclosure relates to a cycle operated foodgrains mill and a method for husking the foodgrains there through efficiently.
BACKGROUND
Husking for foodgrains, for example rice involves removing outer cover of the foodgrains. It is a step which is being practice since ages. In ancient time, husking of the foodgrains involved manual effort in which a big sieve was held and reciprocated manually to remove husk from the foodgrains. As this practice involved lot of manual effort and time, a revolution came towards the advancement of manual husking to machine-based husking. Large number of big machines were developed to perform husking of the foodgrains. However, such machines were quite costly and consumed large amount of space and electricity. Then a substitute for the big machines-cycle powered rice mill manufactured.
The cycle powered based rice mill were conveniently used by farmers for husking the foodgrains involves pedalling of the cycle to perform the procedure of husking. Such a pedalling can be operated manually or through electric power. The conventional cycle powered rice mill though conveniently and effectively is able to husk the foodgrains at nominal cost, however there is a challenge associated therewith. When such a rice mill is pedalled, foodgrains dispensing from a bucket falls on to a set of rollers, the foodgrains have high probability of getting stuck into the rollers as the rice mill is stopped pedalling suddenly. Consequently, an operator needs to clean the rollers primarily, followed by starting a cycle of husking.
Therefore, there exists a need for developing alternative to get rid of aforementioned problems.
OBJECTS OF THE PRESENT DISCLOSURE
An object of the present disclosure is to overcome one or more drawbacks associated with conventional mechanisms.
Another object of the present disclosure is to provide a cycle-powered foodgrains mill to husk the foodgrains in such a way that there is no stucking of the foodgrains in the rollers despite of sudden halting of the mill.
Another object of the present disclosure is to provide a cycle powered foodgrains mill to remove the huck from the foodgrains through a reciprocating sieve.
Another object of the present disclosure is to provide a method for husking the foodgrains through the aforementioned cycle-powered foodgrains mill.

The bucket (102) is fixed and is in vertical alignment. The bucket (102) has a lower opening (102A) in bottom thereof.
The bucket (102) is in alignment with an extruder (104) such that the extruder (104) is connected to the lower opening (102A) of the bucket (102). As shown in unexposed view of Figure 1B, the extruder (104) is placed horizontally. The extruder (104) is configured to be in rotatory motion upon actuating by other components of the cycle mill (100), details thereof explained hereinafter. Rotation of the extruder (10) causes the foodgrains dispensed from the lower opening (102A) of the bucket (102) to move forward horizontally along the axis of the extruder (104). The foodgrains are further configured to exit through a hole (104A) to fall downwards.
The cycle mill (100) includes a roller unit (106) which is in vicinity of the extruder (104). The extruder (104) is in fluid communication with that of the roller unit through a hole (104A). The roller unit (106) includes two roller subunits (106A1, 106A2) which are placed adjacent to each other. As the foodgrains exit through the hole (104A) of the extruder (104), the foodgrains fall downwards on the roller subunits (106A1, 106A2) and get rubbed against the roller sprocket (106A1, 106A2) to separate into processed food grain and husk. Such a motion of the foodgrains ensures no stuck of the foodgrains into the roller unit (106) even if the cycle mill (100) is stopped pedalling all of sudden.
The cycle mill (100) also includes a drive transmission unit (108) in alignment with that of the extruder (104) such that rotation of the drive transmission unit (108) drives rotation of the extruder (104).

The pedal unit (114) includes a pedal crank sprocket (114A) which is in connection with the drive transmission unit (108) through a chain (112). The pedal when operated causes the drive transmission unit (108) to rotate, which further rotates the extruder (104).
There is a gear (110) in alignment with the extruder (104) through an extension (104B). The gear (110) to cause rotation of the extruder (104) as the gear (110) is controlled by the drive transmission unit (108).
As shown clearly in Figures 1A and 1D, a separating unit (116) is disclosed. The separating unit (116) includes a reciprocating sieve (116A) through which husk can be separated from the foodgrains.
The cycle mill (100) also includes a cam and follower drive unit (118) which is attached between a cam shaft (120) and the reciprocating sieve (116A). The cam shaft (120) causes the reciprocating sieve (116A) to move back and forth. A blower fan (122) is attached to the cam shaft (120) and in vicinity of a side sprocket (126). The blower fan (122) configured to blow away the husk of foodgrains through an exhaust pipe (124) connecting to the reciprocating sieve (116A).
Figure 2 discloses a flowchart depicting steps of a method (200) for husking foodgrains via a pedal-operated cycle mill (100). The method (200) involves pedalling the pedal unit (114) followed by rotating the drive transmission unit (108) to further rotate the cam and follower unit (118) and driving the gear (110) simultaneously to rotate the extruder (104) to enable the foodgrains received in the bucket (102) to fall down on the roller subunits (106A1, 106A2). The method (200) involves rotating the roller subunits (106A1, 106A2) and the side sprockets (126), followed by rotating the blower fan (122) to blow away husk from the foodgrains and separating the processed foodgrains from the husk.
