The invention discloses a plough body for a share plough. The plough body comprises a plough share; the plough share and a plough wall are detachably connected to a plough bracket; the plough bracketis connected with a bracket column through a rotary shaft; one end of the rotary shaft is provided with an angle adjustment knob; the connection end of the plough share is provided with a clamping groove; the depth of the clamping groove is identical to the thickness of the plough share; the plough share is in overlapping jointing to the clamping groove and is made of steel; the plough wall is innovatively made of plastics; and the plastics are organic polymer material with compactness being superior than cast iron and are a non-magnetoconductive material and cannot generate adsorption effectwith any mineral substance in soil, so that by adopting the plastics to manufacture the plough wall, the soils cannot be adhered to the plough wall during cultivation, the cultivation resistance can be remarkably lowered, and the mechanical efficiency is improved.
