A kind of yam ditch harvesting machine

Abstract

The invention belongs to the technical field of agricultural machinery and specifically discloses a yam ditching harvester, which includes a power transmission device, a ditching device and a lifting device. The power transmission device includes a reducer and a coupling connected with the reducer. The reducer passes through The drive shaft is connected to the ditching device; the ditching device includes a pair of chains arranged in parallel on both sides of the reducer, the chains are evenly fixed with arc ditching blades, the chains bypass the driving sprocket and the driven sprocket, and the driving sprocket There is a working arm in the chain connected to the reducer, one end of the working arm is connected to the driven sprocket, and the other end is connected to the lifting device; the working arm is connected with a tensioning sprocket and a spiral soil tensioning sprocket that cooperate with the chain. A spiral earthmover is arranged on the tensioning sprocket of the spiral soil discharge; the lifting device includes a hydraulic cylinder connected with a bracket connected to the working arm. The invention has reasonable structure, high working efficiency and low cost.

[0002] Yam is a tuber plant with high nutritional value. It contains precious medicinal and practical values. The development of yam will improve my country's economic level, effectively solve my country's "three rural" problems, and vigorously promote the industrialization and technicalization of rural planting. , specialization is of great significance. According to the existing technology, the harvesting of yams is mainly done manually. Although there are some new designs for harvesting yams with the help of mechanical force, because yams are buried deep in the soil, other The specific growth and length are not easy to grasp, and because of the delicate characteristics of yam itself, it is easy to break or damage the yam if it is slightly touched, which will seriously affect the quality of the yam. The design scheme to ensure the quality of yam harvesting, but manual excavation with a shovel can only dig about 30 meters per day, and the problem of damage rate cannot be guaranteed. Undoubtedly, manual methods are labor-intensive and production efficiency is low.
