Deep-rhizome crop harvester

Abstract

The invention relates to a deep-rhizome crop harvester. The deep-rhizome crop harvester comprises a rack, a transmission device, a deep excavation device and a transport device, wherein the transmission device provides power for a main shaft of the deep excavation device so that the main shaft rotates; the deep excavation device further comprises a supporting frame, a driven shaft, at least one ridge cutting mechanism and at least two ditching mechanisms, the end, close to the rack, of the supporting frame is provided with the main shaft, the end, close to the rack, of the supporting frame isrotationally connected with the rack, the end, away from the rack, of the supporting frame is provided with the driven shaft and connected with the transport device, the ridge cutting mechanism is fixed on the driven shaft and rotates along with the driven shaft; each ditching mechanism comprises a large chain wheel, a ditching chain with a chain cutter and a small chain wheel, the large chain wheel is fixed on the main shaft, the small chain wheel is fixed on the driven shaft, the ditching chain drives the small chain wheel to rotate, the ridge cutting mechanism is arranged between the smallchain wheels of the adjacent two ditching mechanisms, and the ridge cutting mechanism is provided with blades used for cutting ridges. The deep-rhizome crop harvester has the advantages of good excavation quality and high harvesting efficiency.

Description

technical field [0001] The invention relates to a deep root crop harvester, which is especially suitable for yam digging and belongs to the field of mechanical digging. Background technique [0002] Among deep root crops, yam is more difficult to harvest. According to statistics, the current planting scale of yam has not only not increased, but is also facing a shrinking situation. The main reason is the special growth environment of yam, the harvest of yam tubers and the depth and looseness of the planting soil, the surface soil layer and the density of yam. The varieties are highly correlated, the labor intensity and difficulty of excavation and harvesting are very high, the level of mechanized harvesting is low, most areas still use manual harvesting, and the excavation depth is relatively deep (the excavation depth is between 0.8 meters and 1.5 meters), while Farmers who plant yam are generally older, and the yam industry is facing a situation where there are people who...

AI Technical Summary

Problems solved by technology

The excavated area is not sufficient, and the amount of excavated soil is limited, so it cannot be guaranteed that all the yams can be exposed to the soil surface during the vibration process.

At the same time, the position of the soil conveyor is fixed on the frame and cannot be changed with the change of the excavation depth and angle, please refer to the attached drawing of the manual figure 2 , when the trench machine digs deep, the distance between the soil conveyor and the chain excavation belt is very far, it is difficult to drop the excavated soil on the soil conveyor, which will inevitably increase the forward resistance of the harvester
