This creation system provides a kind of multiple group type automatic feeding device,Be by feeder,Positioning button bar and driving device are formed； Wherein,Rail groove is opened up in the Hou side of the feeder,And be provided in what track slot one can carry out,The movement button block of shifting is pulled down,And hook section is convexly equipped in the button block,And the both ends projection rail block of the positioning button bar,Hou is planted for positioning the rail block of button bar using the track slot of feeder,And by going on the rail block of the hook section hook what positioning button bar of mobile button block into locator,And the positioning button bar is separately recessed with accommodation groove,What Hou side separately offers the locking holes person for drive rod locking,And the driving device is then mainly to be made of motor and drive rod,Drive rod is subject to locator using locking holes,Thereby,It can optionally and voluntarily expand the feeder of group number needed for setting,And by starting driving device,So that drive rod rotates,And feed screw rod rotation inside feeder is driven simultaneously,And feed is synchronized,The device for feeding person of multiple groups feeder movement can be thereby driven simultaneously.本創作係提供一種多組式自動餵食裝置，要係由餵食器、定位扣桿及驅動裝置所組成；其中，在該餵食器之後側開設有軌槽，並於軌槽上設置有一可進行上、下拉移之移動扣塊，並在該扣塊上凸設有勾扣段，而該定位扣桿之兩端凸設有軌塊，利用餵食器之軌槽供定位扣桿之軌塊插置後，並藉由移動扣塊之勾扣段勾扣於定位扣桿之軌塊上而行成定位者，而該定位扣桿另凹設有容置槽，於後側另開設有供驅動桿鎖固之鎖合孔者，而該驅動裝置則主要係由馬達及驅動桿所組成，利用鎖合孔將驅動桿加以定位者，藉此，可視需要而自行擴置所需組數之餵食器，並藉由啟動驅動裝置，使得驅動桿旋轉，並同時帶動餵食器內部飼料螺桿轉動，而進行同步供料，藉此可同時驅動多組餵食器動作之餵食裝置者。
