CONCEPT AND WORKING
n this project for dri//in0 +.B (P AC motor is used' for contro//in0 the depth of dri//' /ead screw mechanism is used which is contro//ed by a 3C motor' hopper is p/aced on the frame in which the seed is p/aced. n the hopper a 0ear with 3C motor is used to contro/ the number of seed f/owin0 in to the 0round. #his seed is f/ow throu0h the f/e2ib/e pipe which is connected to frame. #he f/attener consists of hard rubber tis made up of MS p/ate fi// the di0ed sand in to the ho/e. Additiona/ to the above dribb/in0 mechanism another ro//er p/ou0h mechanism is attached to the tro//ey. #his wi// increase the yie/d of crops. #he ;"H;?? switches) Bway switches is p/aced on the hand/e. #his is used for a// the mechanisms. t consists of whee/ on the base used for mobi/ity.
9y the above comparison it is know that in concept)B add to the dribb/in0 process another p/ou0hin0 is used. So whi/e p/ou0h the fie/d addition to the dribb/in0 method' the new soi/ wi// comes and weed wi// be removed. So the advanta0e in concpt)B is more. So based on this concept)B is se/ected for fabric ation and verification.

n this project it has B 3C motor and B AC motor. ;ne AC motor is used for rotary p/ou0h which is connected to the rotary p/ou0h by he/p of chain and sprocket. #he input of the motor is direct/y connected to main' when switch is ;" the motor rotates the p/ou0h which p/ou0hs the /and.
;ne more AC motor is connected with au0ur too/ which is used for dribb/in0 the /and. #he input of the motor is direct/y connected to main' when switch is ;" the motor rotate the au0ur too/ which dri//s the /and.
;ne 3C Motor is used for contro/ the depth of the dri// in the /and with he/p of /ead screw mechanism. t has 3P3# switch which reverse the current of the 3C motor so the motor rotate forward and reverse' hi/e forward motion the dri// feed into the /and' hi/e reverse direction the dri// outward from the /and. #his 0et power source from the @B% battery.
;ne 3C motor is used for seed sowin0. t has the SP3# switch whi/e ;" the switch the motor rotate the shaft it has sma// depression which carry the seed and drop in the di00ed ho/e.
t has the f/attener which is attached at the frame' when the tro//ey moves the f/attener wi// c/ose the di00ed ho/e by /oose soi/. #he tro//ey wi// be operated by manua//y

=% E3PERIMENT AND *A2IDATION #he Semi)automatic seed sowin0 machine was taken for e2periment. 9y ;" the switch of the rotary p/ou0hin0 the rotary p/ou0h' P/ou0h the /and. 9y ;" the dri//in0 machine for dribb/in0 and ;" the 3C motor the dri//in0 is done on the p/ou0hed /and to the specific depth. #hen ;" the Seed sowin0 motor the seed is dropped in the di00ed re0ion. #hen by movin0 the tro//ey the di00ed re0ion is fi//ed with /oose Soi/.

#hus the resu/ts are satisfied when compared to manua/ p/ou0hin0 process and seed sowin0 process.
>% CONC2USION #hus the desi0n and fabrication of seed sowin0 machine' which reduce the man power' which is used for p/ou0hin0' dribb/in0' seed sowin0. t a/so reduces the
effort of farmer. #his process the seed sowed in proper depth. t is cost competitive. Seed spi//a0e is avoided.
t is portab/e in si8e and can be easi/y transportab/e. t is simp/e in construction. t is easy to maintenance. t is user friend/y. #his project use e/ectric power source so "osie free operation. t can be used sma// a0ricu/ture /and. t a/so used for form house a0ricu/ture. t can be used for mu/ti croppin0 purpose
n this project both p/ou0hin0 and dribb/in0 process is done so the upper /ayer of soi/ wi// 0oes down and fresh soi/ wi// comes up. So the crop wi// yie/d more productivity.
,% OPPORTUNIT+ @. #he seeds can be p/aced at proper depth. B. Mi2ed croppin0 can be easi/y done.
=. t maintains the proper row spacin0.
>. #he seeds can be p/aced at proper depth.
. Mi2ed croppin0 can be easi/y done.
*. t maintains the proper row spacin0.
6. 3ue to sma// si8e machine is portab/e. And can a/so be used in sma// area.
,. Cost efficient.
@% Reduce Man Power.
FUTURE SCOPE
@. #his project can be used as a 0ras s cutter' by rep/acin0 the au0ur too/ by 0rass cutter. 9y this it is used as doub/e purpose.
B. 9y usa0e of servo motor or stepper motor the process can be automated so it wi// reduce the further effort of farmer. =. Usa0e of mu/ti)hopper' seed sowin0 can be done side by side for /ar 0e farm >. Usin0 remote contro/ process this device can be made automatic without human intervention. . 9y addin0 the ferti/i8er sprayin0 process comp/ete feature wi// incorporated.
