Land plowing and preparation device for sweet potato planting

Abstract

The invention discloses a land plowing and preparation device for sweet potato planting. The land plowing and preparation device comprises a vehicle frame, a rotary tillage unit and a leveling unit, wherein the rotary tillage unit and the leveling unit are mounted on the vehicle frame; the rotary tillage unit comprises rotary tillage assemblies, a first rotating disc, a first connecting rod and a mounting rod; the leveling unit comprises a second motor, a second rotating disc, a movable rod, a pressing rod and a leveling plate; and a soil crushing unit is arranged between the rotary tillage unit and the leveling unit, and the soil crushing unit comprises a hollow shaft, a driving mechanism for driving the hollow shaft to rotate, a fourth rotating disc, a third rotating disc, a second connecting rod, a supporting rod and a crushing blade. The rotary tillage unit is arranged, so that the working efficiency is improved while the rotary tillage assemblies are effectively protected; the rotary tillage depths of the three groups of rotary tillage assemblies are synchronously adjusted to meet different working requirements; the leveling unit is arranged, soil is flattened and trowelled, and a better leveling effect is achieved; and the soil crushing unit is arranged, a movable block drives a driving rod to reciprocate, the movement range of the supporting rod is further expanded, and the soil crushing efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of land consolidation, in particular to a land consolidation device for planting sweet potatoes. Background technique

[0002] Sweet potato: Also known as sweet potato, it is a twining herbaceous vine of the genus Dioscorea in the family Dioscoreaceae. The top branch of the underground tuber is swollen into an ovoid tuber with light yellow outer skin and smooth. Stems left-handed, spiny at base, covered with T-shaped pilose.
