Embodiment 1
[0034] Example 1: Such as figure 1 , figure 2 , image 3 , Pic 4-1 , Figure 4-2 , Figure 5 , Figure 5-1 , Figure 5-2 , Figure 5-3 As shown, a bionic rolling rake based on the biological characteristics of the soil is mainly composed of a rolling basket, a bionic rake blade and a frame. The rolling basket 1 is provided with a bionic rake blade 2, and the bionic rake blade 2 includes a scale structure 4 with bionic ribs. The soil contact surface and the cutting edge of the bionic sawtooth structure 5;
[0035] Further, the scale micro-thorn structure on the soil-contacting surface with the bionic ribbed scale structure 4, the scale shape is an ellipse, and the major axis a and the minor axis b are assigned according to the side plate and the harrow structure of the rolling basket 1. a=7.5 mm, b=5 mm, namely: x 2 / 7.5 2 +y 2 / 5 2 = 1, take the thickness of the scale H=0.5 mm;
[0036] Further, a bionic ribbed structure 6 is distributed on the scales, and the ribbed cross secti...
Embodiment 2
[0039] Example 2: Such as figure 1 , figure 2 , image 3 , Pic 4-1 , Figure 4-2 , Image 6 , Figure 6-1 , Figure 6-2 , Figure 6-3 As shown, a bionic rolling rake based on the biological characteristics of the soil is mainly composed of a rolling basket, a bionic rake blade and a frame. The bionic rake blade has a soil contact surface with a bionic ribbed scale structure and a blade with a bionic sawtooth structure;
[0040] Further, the scale micro-thorn structure on the soil-contacting surface with the bionic ribbed scale structure 4, the scale shape is an ellipse, and the major axis a and the minor axis b are assigned according to the side plate and the harrow structure of the rolling basket 1. a=10 mm, b=7.5 mm, namely: x 2 / 10 2 +y 2 / 7.5 2 = 1, take the scale thickness H=1 mm;
[0041] Further, a bionic ribbed structure 6 is distributed on the scales, the cross-section of the ribs is triangular, and the height of the triangle is h=1mm, the rib height is 1 mm, and the rib...
Embodiment 3
[0044] Example 3: Such as figure 1 , figure 2 , image 3 , Pic 4-1 , Figure 4-2 , Figure 7 , Figure 7-1 , Figure 7-2 , Figure 7-3 , Figure 7-4 As shown, a bionic rolling rake based on the biological characteristics of the soil is mainly composed of a rolling basket, a bionic rake blade and a frame. The bionic rake blade has a soil contact surface with a bionic ribbed scale structure and a blade with a bionic sawtooth structure;
[0045] Further, the scale micro-thorn structure on the biomimetic soil-contacting surface, the scale shape is an ellipse, the major axis a and the minor axis b are assigned according to the side plate of the rolling basket and the harrow blade structure, taking a=12 mm, b=8 mm, namely: x 2 / 12 2 +y 2 / 8 2 = 1, take the thickness of the scale H=0.5 mm;
[0046] Further, a bionic ribbed structure is distributed on the scales, the ribbed cross section is a quadratic curve, and the quadratic function curve-shaped ribbed cross section has a function of...
