The invention discloses a control device and a control method for appropriate feeding and discontinuity prevention of a tobacco storehouse type feeding machine. A material probing detection element for detecting materials is arranged on a framework of the tobacco storehouse type feeding machine; the material probing detection element is arranged in the inclined upper direction of the bottom of an elevating belt; a timer is arranged on the tobacco storehouse type feeding machine; and the timer, the material probing detection element, a control system of the elevating belt and a control system of a bottom belt are separately connected with a control unit. The control device and the control method disclosed by the invention have the beneficial effects that different functions are formed by the material probing detection element according to the duration time, and the appropriation and the timeliness of supplying materials by the bottom belt are improved; according to real-time existing conditions of the materials in a connecting area between the bottom belt of a material storehouse and the elevating belt, unified control is carried out by the control system, so that the bottom belt is enabled to timely provide materials which are sufficient but not excessively supplied to the elevating belt; and by arranging the timer, an alarming system and a speed sensor, effective monitoring for the bottom belt is realized, and the continuousness of production is guaranteed.
