Description

Technical Field

[0001] This patent relates to the technical field of root crop harvesting in agricultural machinery, in particular to a lightweight variable amplitude swing deep root medicinal material harvester. Background Art

[0002] Mechanized harvesting of root crops primarily involves the comprehensive process of excavating the underground rhizomes from the soil and effectively separating them from the soil. Currently, excavation is typically accomplished using fixed or vibrating shovels, while separation is accomplished using screening components such as lifting chains, vibrating screens, and crushing rollers. These components are typically separate, resulting in a complex structure. Furthermore, the movement of the root-soil mixture through the separation components takes a long time, resulting in relatively high energy consumption. At present, typical root crop harvesting equipment mainly includes several types, such as shovel-screen combination, shovel-chain combination, and shovel-roller combination. For example, a long-root Chinese medicinal material excavator (CN110063115A) adopts a vibrating excavation shovel and a soil-breaking roller combination operation mode to achieve vibration and crushing and screening during the transportation of medicinal materials; a long-root crop vibrating excavation shovel (CN110036750A) adopts a cam mechanism to drive the excavation shovel + grid separation screen to perform two-dimensional vibration operation, integrating multiple processes such as vibration drag reduction, vibration crushing, crop separation, and soil turning, which can improve the operation depth and efficiency; a dual-vibration deep-root crop excavator (CN101473727B) adopts the reciprocating vibration technology of the excavation shovel and the plow blade. The plow blades on both sides cut the soil, and the crop roots gradually rise from the bottom of the separation device and are separated from the soil. In order to achieve the requirements for deep-rooted medicinal material harvesting (harvesting depth exceeds 40cm), large-scale, multi-stage designs and measures such as increasing vibration (shake) intensity are usually adopted to improve processing capacity and separation efficiency. These designs have caused new problems such as complex structure and transmission, and reduced strength and reliability of the whole machine. There is an urgent need to develop new excavation and separation components and lightweight deep-rooted medicinal material harvesters. Summary of the Invention
