Tobacco field ridging machine automatically protecting leaves

Abstract

Intertillage ridging is an important link in the field management of cured tobaccos, but tobacco leaves are easily crushed during the ridging. The existing tobacco field ridging machines do not solve the problem. The present invention discloses a tobacco field ridging machine automatically protecting leaves. During the work, helical blades are driven by a power-driven auger shaft to rotate, soil is loosened by a rotary tillage cutter, the soil loosened is pushed to the two sides by the helical blades and thrown to ridge top by the force of inertia, and the soil is ridged. A ridge top copying plate and ridge side copying plates are closely attached to ridge surfaces, tobacco leaves laid on the ridge surfaces are held up by the copying plates, and the tobacco leaves held up slip across leaf plates and leaf protecting grids as a trailer advances. The tobacco leaves are prevented from being buried by the soil during the ridging. The ridging machine can adapt to different ridge spacings by changing the helical angle of the helical blades, and can adapt to different ridge widths by adjusting the sheathing distance of the leaf protecting grids with a machine frame. As the radius of the helical blades is smaller than the work radius of the rotary tillage cutter, the soil loosened can not be all pushed to ridge top. One layer of loosened soil is kept on ridge bottom, which is favorable for preservation of soil moisture.

Description

technical field [0001] The invention relates to a flue-cured tobacco field cultivator, in particular to a tobacco field cultivator capable of automatically protecting tobacco leaves from damage, and belongs to the field of agricultural machinery. Background technique [0002] Intertillage and soil cultivation is an important part of flue-cured tobacco field management. The workload of intertillage and soil cultivation occupies a large proportion in the field management of flue-cured tobacco. It is one of the measures to ensure high-quality, high-yield and stable production of flue-cured tobacco. According to the agronomic requirements of flue-cured tobacco planting, when the flue-cured tobacco grows to 4 to 5 tobacco leaves, it needs to be cultivated. However, the tobacco leaves are long and soft, and the bottom tobacco leaves are basically pulled on the ground. It is difficult to avoid crushing the tobacco leaves when cultivating the soil, and the crushed Tobacco leaves dir...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defect that the existing tobacco field cultivating machine cannot solve the problem that the soil is crushed and damages the tobacco leaves, and discloses a tobacco field that uses a rotary tiller to loosen the soil and cooperate with a spiral blade to agitate the dragon to cultivate the soil, and can automatically protect the tobacco leaves from being crushed Cultivator
