Provided is a wheat broadcast sower capable of achieving uniform coverage, comprising a machine frame (3), wherein a soil covering box (10) is provided below the machine frame (3)； multiple rollers (1) are further provided below the machine frame (3)； two ends of the machine frame (3) are connected to the soil covering box (10) by means of connecting plates (2)； support columns (44) are symmetrically provided at the bottom of the soil covering box (10)； a rotary shaft (34) is rotatably connected inside the soil covering box (10)； a pair of moving plates (33) are provided at the bottom of the soil covering box (10)； a driving mechanism is provided on the support column (44), and the driving mechanism is connected to the rotary shaft (34) and the moving plates (33)； a slide rail (4) is provided on the machine frame (3), and multiple moving blocks (15) are connected inside the slide rail (4) in a sliding manner； and both sides of the moving block (15) are connected, in a clamped manner, to a clamping shaft (12). The wheat broadcast sower is simple in operation, and by means of the mutual cooperation of the machine frame (3), broadcast sowing rotary wheels (9) and the soil covering box (10), wheat seeds can be uniformly sowed, thereby effectively avoiding non-uniform sowing spacing due to the centrifugal force and at the same time being capable of automatically adjusting the thickness of the soil covering the wheat seeds.La présente invention concerne une semeuse de diffusion du blé capable d'atteindre une couverture uniforme, comprenant un châssis de machine (3), une boîte de recouvrement du sol (10) étant disposée au-dessous du châssis de machine (3) ； de multiples rouleaux (1) sont en outre disposés au-dessous du châssis de machine (3) ； deux extrémités du châssis de machine (3) sont reliées à la boîte de recouvrement du sol (10) à l'aide de plaques de connexion (2) ； des colonnes de support (44) sont symétriquement disposées au fond de la boîte de recouvrement du so
