PROBLEM TO BE SOLVED: To provide a seeding apparatus which can prevent that seeds are washed out with muddy water to reduce the amount of seeding, can prevent the scattering of the seeds in a releasing cylinder, and hardly peels the coatings of the seeds.SOLUTION: The seedling apparatus which is manufactured by disposing a seeding device for seeding seeds stored in a seed tank on a field behind a travel vehicle body through a lifting or lowering link device, disposing a releasing cylinder 90 under the seed tank in a communicated state, and rotatably disposing a delivery rotator 88 for delivering seeds in a seed delivery portion below the seed tank and above the releasing cylinder 90, and seeding the seeds delivered from the delivery rotator 88 on a field through a delivery passage 117 in the releasing cylinder 90, is characterized by disposing a mud-removing member 110 for preventing the invasion of mud and the like into the delivery rotator 88 in the releasing cylinder 90 and under the delivery rotator 88, and disposing projections 111a, 111b for controlling the movements of the seeds delivered from the delivery rotator 88 in the right and left directions of the machine frame on the mud-removing member 110.COPYRIGHT: (C)2011,JPO&INPIT【課題】泥水に種子が流されて播種量が減少することを防止し、放出筒内での種子散乱を防ぎ、種子のコーティング剤が剥がれ難い播種装置を提供する。【解決手段】種子タンクに貯留した種子を圃場に播種する播種装置を走行車体の後部に昇降リンク装置を介して設け、種子タンクの下部に放出筒90を連通し、種子タンクの下方で且つ放出筒90の上部の種子繰出し部に種子を繰り出す繰出し回転体88を回転可能に設け、繰出し回転体88から繰り出される種子を放出筒90内の繰出し通路117を経由して圃場に播種する播種装置において、放出筒90内で且つ繰出し回転体88の下方に繰出し回転体88への泥等の侵入を防止する泥除け部材110を設け、泥除け部材110の上部に繰出し回転体88から繰り出された種子の機体左右方向への移動を規制する突起体111a,111bを設けて構成する。【選択図】図5
