Novel furrow plow curved surface

Abstract

The invention relates to a novel furrow plow curved surface. The plow curved surface is of a pseudo-spherical shape; a plowshare, a plow breast and a plow wing of the plow curved surface are of a complete curved-surface sheet and have the characteristics of a chiseling plowshare, a convex breast and a swept wing; the plowshare and a plow wall are separately manufactured and are convenient to repair and replace; the resources are saved. According to the novel furrow plow curved surface, the pseudo-spherical surface with a gauss curvature being a negative constant curvature is innovatively used as the plow curved surface; the negative constant curvature K is -1 / 1600; compared with other plow curved surfaces, the plow curved surface is high in smoothness; the plow curved surface has the effect of more effectively turning and breaking the soil; the tillage resistance and the energy consumption are reduced; the problems that the gauss curvature of the current furrow plow curved surface cannot be highly integrated to be the same curvature, the tillage resistance is high, the energy consumption is high and the plow curved surface is high in soil adhesion can be solved; the novel furrow plow curved surface is simple in structure, accurate to manufacture and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of agricultural tillage machinery, in particular to a curved plow body of a novel conventional plow. Background technique [0002] Cultivated land is the most basic operation in agricultural farming system. Its purpose is to loosen the soil, cover weeds, prevent diseases and insect pests, and create favorable conditions for the growth and development of crops. Commonly used farming machines include plows, disc plows, harrows, rotary tillers, subsoiling plows, etc. Among them, the plow is the oldest, largest and most widely used farming machine in agricultural production. During plow cultivation, the soil is broken and turned along the surface of the plow body to complete the loosening and turning of the soil and achieve the purpose of soil cultivation. Since the force of the soil on the plow body mainly acts on the plow body surface, the shape and parameters of the plow body surface directly affect the qual...

Problems solved by technology

The Gaussian curvature of the plow body surface formed by the traditional design method is highly concentrated near the same curvature value, and it is impossible to make the Gaussian curvature of each point on the plow body surface be the same curvature value, which makes the smoothness of the plow body surface poor, resulting in poor quality of the plow body surface , The traditional plow body has severe clay properties under the condition of cohesive soil cultivation, weak soil turning and crushing performance, large cultivation resistance, low efficiency, and increased energy consumption. The traditional plow body cannot be manufactured accurately, which makes the surface quality of the plow body uneven. Therefore, it is an objective need to develop a plow plow surface with good performance in turning soil and crushing soil, small tillage resistance, small adhesion, good smoothness, easy manufacturing and accurate manufacturing.
