The working principle and the process are as follows:
the mixed-cutter sectional type double-helix powder ridge cutter moves forwards while rotating reversely, after the inclined cutter 11 of the left cutter contacts soil, the soil is gradually broken and ridged to form soil blocks, but the pushing action on the soil is reduced due to the hollowing of the helical blades, the formed soil blocks are smaller, after the powder ridge cutters of the first section right helical blade 6 of the left cutter and the second section right helical blade 7 of the left cutter contact the soil, the powder ridge blades contacting the soil at the lowest layer cut the soil to separate and break the soil into the soil blocks along with the forward movement and rotation of the blades, the resistance can be reduced due to the sliding cutting action generated when the right helical blades penetrate the soil by the inclined cutter 11 of the left cutter arranged on the first section right helical blade 6 of the left cutter and the second section right helical blade 7 of the left cutter, and the soil blocks generated by pushing are under the action of the first section right helical blade 6 of the left cutter and the second section right helical blade 7 of the left cutter, the soil block moves upwards while rotating, but because the right helical blade is partially hollowed, the soil block moves to the hollowed 10 on the helical blade of the left cutter, one part of the soil block passes through the right helical blade under the action of gravity and falls below the right helical blade, the other part of the soil block passes over the hollowed 10 on the helical blade of the left cutter under the action of inertia, and then the soil block continues to move upwards while rotating under the action of the right helical blade until the soil at the lowest layer is blocked by the first middle bent blade 3 and the second middle bent blade 4 and is cut again, and the soil at the lowest layer cannot continue to rise again. Middle level soil and upper soil can be because the ridge of lower floor's soil plays and the lifting effect to soil of the third section right helical blade 8 of left cutter and the fourth section helical blade 9 of left cutter and upward movement, but because the rotational speed of this part soil piece is less than the rotational speed of powder ridge sword 2, when this part soil piece meets with powder ridge blade, powder ridge sword 2 can produce cutting action to it, the soil that passes fretwork 10 on the left cutter helical blade and part sectional type helical blade except can be because powder ridge sword 2 and cut, the soil that drops downwards can be installed the first middle part tulwar 3 and the second of the middle part tulwar 4 on the two outside helical blade subsection sections of arbor are further broken. Meanwhile, as the helical blades are hollowed out, the rotation speed of the soil blocks is relatively slow, the throwing distance under the centrifugal action is small, and the soil blocks are cut and blocked again by the four upper bent knives 5 arranged at the uppermost end of the cutter shaft 1 after being thrown out, in the process, the soil blocks are cut and blocked again by the ridge smashing knife 2, the first middle bent knife 3, the second middle bent knife 4 and the four upper bent knives 5 alternately due to the speed difference cutting action, so that the soil crushing degree of the ridge smashing knife during working is improved, a better crushing effect is achieved, the stability of a system is kept, the layering state of a soil layer is not damaged, the cutter shaft 1 is a hollow cylinder, the cutter shaft 1 below the first middle bent knife 3 is a disconnected cutter shaft, the blocked and lifted working speed of the cutter can be reduced, and the crushed soil blocks under the surface layer fall back under the action of gravity after the cutter moves through soil mass, ridges are raised, and the soil crushing degree is high.
