Embodiment Construction
[0011] as attached image 3 , 4 As shown in the figure, the body of the plough share is composed of a plough face 1 and a plough handle 2, and the entire plough face 1 is provided with an arc surface facing the rotation direction of the plough blade, and the central angle opposite to the arc face is 50° °, and the axis connecting line on the arc surface R is parallel to the center line in the length direction of the plough shank 2. Since the radius R of the curved surface of the blade surface of the plough blade designed in this embodiment is between 120 and 130 mm, the entire blade surface can have a streamlined curved surface shape. The center line in the length direction of the plough shank is parallel, so that the plough blade can rotate the field soil and throw the soil without any obstruction on the blade surface, and the soil will not remain on the blade surface of the plough blade, and also Ensure sufficient depth of ploughing soil.

The invention relates to a novel furrow plough blade having a streamline-shaped arc surface. The novel furrow plough blade includes a furrow plough blade body; a furrow plough blade surface and a furrow plough handle are arranged on the furrow plough blade body; a bent angle is formed between a bent portion of the furrow plough blade and the body portion; and the central angle of the arc surface of the bent portion is 50-60 degrees. The whole blade surface is a streamline-shaped curved surface; an R axis connection line of the arc surface is parallel to a central line in the length direction of the furrow plough handle, and when the furrow plough blade is used to rotatably cut field soil, obstacles do not exist in the blade surface while the field soil is thrown away; soil will not stay on the blade surface of the furrow plough blade. The novel furrow plough blade can thoroughly turn over the field oil, is small in working power, and is less in energy consumption.
Description
technical field [0001] The invention relates to a new type of plough blade with streamlined camber, in particular to the design of the camber angle of a rotary plough blade, and belongs to the technical field of machinery manufacturing. Background technique [0002] At present, the plough blades used in agricultural rotary tillage machines are shaped like the attached figure 1 As shown, the body of the plough blade is provided with a coulter face a and a plough handle b, and an arc surface that is bent towards the rotary cutting direction of the plough blade is provided at the length direction of the coulter face a near the end. A certain angle is formed between them, which is set up to make the soil spin more thoroughly. In practice, it is found that the arc r of the arc surface of this traditional plough blade is small and the setting position of the arc surface is unreasonable. During the tillage, the plough blade with a certain speed rotates the soil in the tangential d...
