The present invention provides a waste cotton flat oyster mushroom seed automatic inoculating device, wherein the device is automatically driven on fungi, and a waste cotton and a seed are evenly mixed and inoculated. A height of the waste cotton is made to be flat, thereby reducing labor force. Electric stability and driving properties are improved, thereby improving agricultural competitiveness. The waste cotton flat oyster mushroom seed automatic inoculating device can contribute to an increase in agricultural income. To this end, the waste cotton flat oyster mushroom seed automatic inoculating device for mixing and inoculating a waste cotton and a seed while driving along rails formed in both sides of fungi comprises: a driving vehicle driven by receiving electric power from a driving motor having a wheel seated on a rail； and an agitating vehicle hinge-coupled to be rotated in a front or a rear side of the driving vehicle, and agitating the waste cotton by receiving electric power from an agitation driving motor having an agitation blade part formed to be rotated therein. According to a technical structure thereof, the device is remotely controlled to be automatically driven on fungi, so the waste cotton and seed are evenly mixed and inoculated, thereby reducing labor force. Moreover, a battery is installed, and the device is operated at a low voltage, so the device can be electrically safely operated in a humid mushroom growing area. Moreover, the device releases tangles waste cotton, and makes both sides of the waste cotton inwardly develops, so driving stability and waste cotton height can be averaged. Consequently, agricultural competitiveness can be improved, and the device can contribute to an increase in agricultural income.본 발명은 균상을 자동으로 주행하면서 폐면과 종균을 고르게 섞어 접종하고 폐면 높이가 균평하도록 하여 노동력을 절감하는 한편 전기적 안전성 및 주행성의 개선으로 농가의 경쟁력 향상을 도모하고 농가의 소득증대에 기여할 수 있는 폐면 균평 느타리버섯 종균 자동 접종기를 제공한다. 이를 위하여 본 발명은 균상 양측에 부설된 레일을 따라 주행하면서 폐면과 종균을 섞어 접종하는 느타리버섯 종균 자동 접종기에 있어서, 레일
