Problems solved by technology
When performing deep plowing operations on the ground in the greenhouse, because the farmers set up a column every three meters or so in the greenhouse to support the shed body, the common plow will leave ditches on the traveling distance due to its side-turning characteristics, making it difficult to level the land , it is also easy to damage the stability of the column, making it difficult for ordinary conventional plows to be used in greenhouses

Embodiment Construction
[0025] A plow surface design method for an in-situ tillage plow, including plowshare 1 parameter design, guide curve parameter design, and soil plowing curve element line change law, wherein the plowshare 1 parameter includes plowshare cutting angle, soil cutting angle and load angle , the turning curve element line includes the change rule of the element line angle and the change rule of the turn curve. When plowing the soil on the spot, the process of turning the soil furrow by the curved surface of the plow body to the original furrow can be divided into: the process of raising soil Ⅰ, turning the soil Failing process Ⅱ and buckling process Ⅲ, soil raising process Ⅰ: cutting angle θ 0 is the angle between the plowshare blade and the forward direction of the plow body, θ 0 angle range 45° , cut soil angle ε is the angle between the plowshare 1 and the ground at the end of the plowshare 1 on the section perpendicular to the advancing direction of the plow body, ε Angle...

The invention provides a plow body curved surface design method of an on-site soil turning plow. The method comprises the steps of plow share parameter design, guide curve parameter design and soil turning curved element line change rule, wherein the parameters of the plow share comprise a plow share cutting angle theta 0, a soil cutting angle epsilon and a load angle alpha, the soil turning curved element line comprises an element line angle change rule and a soil turning curve change rule, and the design parameters of the plow share are firstly determined according to the plow share blade angle theta 0, the soil cutting angle epsilon, the furrow width, namely the plow furrow width d and the load angle alpha. And then a guide curve parameter and a meta-line angle change rule theta= f (y)are determined, a main plow body curved surface contour is determined, and finally an auxiliary surface is added to complete plow body curved surface design, thereby completing the design of the on-site soil turning plow body curved surface.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a plow body curved surface design method of an in-situ plow. Background technique [0002] In my country's facility agriculture, due to consideration of the convenience of circulation, farmers mostly plant crops repeatedly, which leads to the breeding of germs, so it is urgent to carry out plowing operations. When performing deep plowing operations on the ground in the greenhouse, because the farmers set up a column every three meters or so in the greenhouse to support the shed body, the common plow will leave ditches on the traveling distance due to its side-turning characteristics, making it difficult to level the land , It is also easy to damage the stability of the column, making it difficult for ordinary conventional plows to be used in greenhouses. The in-situ plow can solve the above problems because of its ability to turn over the original ditch without si...
