The present invention provides a quantitative feeding supply device. The device has a main boy having a lower end forming a protrusion. The main body also forms a through hole corresponding to the protrusion for receiving a rod extended from a knob. The rod is also inserted into a central hole of a ball-type element and then let the rod abuts against the space of the protrusion of the main body. The protrusion of the main body and the rod of the knob of the main body abut against spaces of a frame body respectively so as to let the main body be set on the frame body stably and the frame body also can have a container so that when the user rotate the knob, the knob can drive the ball-type element to rotate together and let the feed between the dividing portion of the ball-type element drop into the container to supply the feed quantitatively.本發明是提供一種定量飼料供給器,是採在一主體的靠下一端一側周邊形成一卡掣凸部、及在卡掣凸部的相應周邊貫穿一孔,以配合一旋鈕延伸的一截桿段引入主體的孔、並使該截桿段切入一撥切件的中心孔,在使桿段另端為抵靠在主體的卡掣凸部其相應空間;而該主體一側周邊的卡掣凸部及另端貫穿的旋鈕該截桿段靠外部位則是各別抵靠在架體上端周邊的相應空間,以使主體平穩跨設在架體上端,而在架體其間是可置入一容器;以利手部在轉動旋鈕一併驅使撥切件作轉動,能將主體內部為每兩區隔部之間的飼料撥動並朝落料口落入容器,以達到簡便的定量供給。(1)‧‧‧主體(11)‧‧‧卡掣凸部(111、61、62)‧‧‧空間(12)‧‧‧孔(13)‧‧‧入口(14)‧‧‧落料口(2)‧‧‧撥切件(21)‧‧‧區隔部(22)‧‧‧中心孔(3)‧‧‧旋鈕(31)‧‧‧桿段(4)‧‧‧蓋體(5)‧‧‧出口蓋(6)‧‧‧架體(7)‧‧‧容器(8)‧‧‧飼料供給器
