Problems solved by technology
In practice, it has been found that the arc r of the arc surface of the traditional plow blade is relatively small and the setting position of the arc surface is unreasonable. The plow blade with a certain rotational speed cuts the field soil and rotates along the tangent direction of the rotary tiller. Throwing, due to the small angle of the arc surface of the plow blade, a small part of the thrown field soil is attached to the most concave part of the arc surface of the end of the plow blade. The weight of the plow blade itself is increased, and the energy consumption is increased. For a rotary tillage shaft with several plow blades, the total energy consumption is quite large.

Embodiment Construction
[0011] as attached image 3 , 4 As shown, the plow blade body is composed of the plow blade surface 1 and the plow handle 2, and the entire plow blade surface 1 is provided with an arc surface facing the rotation direction of the plow blade, and the central angle of the arc surface is 50°. °, and the line connecting the axes on the arc surface R is parallel to the centerline of the plow handle 2 in the length direction. Since the radius R of the curved arc surface of the plowshare blade designed in this embodiment is between 120 and 130 mm, the entire knife face can be made to have a streamlined curved surface shape, and because the line connecting the R axis on the arc surface and The center lines in the length direction of the plow handle are parallel, so that the plow blades can be rotated to cut the field soil and thrown out without any hindrance on the blade surface, and the soil will not remain on the blade surfaces of the plow blades. At the same time, it also ensures...

The invention relates to a novel furrow plough coulter which comprises a furrow plough coulter surface and a furrow plough handle arranged on a furrow plough coulter body. The novel furrow plough coulter is characterized by a bending angle between a bent part and a body part of the furrow plough coulter body, and the central angle corresponding to a cambered surface of the bent part ranges from 50 degrees to 60 degrees. Therefore, the whole coulter surface takes the shape of a streamline form cambered surface; because an R-axis connecting line on the cambered surface and a center line in the length direction of the furrow plough handle are parallel, no obstacle exists when the furrow plough coulter is used for rotationally cutting and throwing out field soil, and no soil remains on the furrow plough coulter surface. The novel furrow plough coulter has obvious advantages of thorough soil, low work power, low energy consumption and the like.
Description
technical field [0001] The invention relates to a novel plow blade, in particular to the design of the arc angle of the blade of a rotary plow, and belongs to the technical field of mechanical manufacturing. Background technique [0002] At present, the plow blades used in agricultural rotary tillage machinery are shaped as attached figure 1 As shown, the body of the plowshare is provided with a coulter surface a and a plow handle b, and at the end of the length direction of the coulter surface a is provided with an arc surface that bends toward the direction of the plow blade rotary cutting. A certain angle is formed between them, which is set up to make the field turn over more thoroughly. In practice, it has been found that the arc r of the arc surface of this traditional plow blade is relatively small and the setting position of the arc surface is unreasonable. The plow blade with a certain rotational speed cuts the field soil and rotates along the tangential direction ...
