Harvesting device capable of realizing layered collection and soil removal

Abstract

The invention relates to the technical field of agricultural harvest machinery and discloses a harvesting device capable of realizing layered collection and soil removal. The harvesting device comprises a positive-rotation soil crushing wheel, a reverse-rotation soil crushing wheel, a collecting shovel, a soil collecting plate, a soil discharge helix, a rack, a material collecting helix and a conveying separating part, wherein the positive-rotation soil crushing wheel, the conveying separating part, and the material collecting helix form an upper layer collecting and separation mechanism; the reverse-rotation soil crushing wheel, the collecting shovel, the conveying separating part and the material collecting helix form a lower layer collecting and separation mechanism; according to a layered harvesting method of cyperus beans, soil of a whole soil layer is excavated and collected by two layers, and excavation, collection and soil separation are carried out by the upper layer collecting and separation mechanism and the lower layer collecting and separation mechanism simultaneously, so that an instantaneous separation area of unit soil is increased, the problem of the whole soil layer harvesting method that separation of the cyperus beans and soil is difficult is solved, and cyperus beans layered-collection soil-removal paving sectional type harvesting operation is realized.

Description

technical field [0001] The invention relates to a layered collection and soil clearing harvesting device, which belongs to the technical field of agricultural harvesting machinery, and in particular to a layered collecting and soil clearing harvesting operation equipment for oily bean. Background technique [0002] The origin of oily bean is Africa. It is a high-quality and high-yield oil crop and belongs to the annual plant of Gramineae. It can be planted on beaches, hillsides, hills, and forests in the north and south of my country. It is resistant to drought and waterlogging, and is easy to grow and manage. The grass grows on the ground, up to 100-120cm high, with fibrous roots, strong tillering ability, growing in clusters, flat and thick leaves, slender and sword-shaped, with a yield of more than 3000kg of fresh grass per mu. It is suitable for raising cattle, sheep, High-quality feed for fish, rabbits and geese. Youshadou mainly harvests underground nuclear rhizome f...
