Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, and in particular to a yam harvester. Background Art

[0002] With the development of the edible value and medicinal value of yam, many people began to eat yam, and the scale of yam cultivation gradually increased. Generally, yam is planted in an area of ​​more than ten acres. At this time, we need to realize that harvesting yam requires an automated machine. This automated machine will greatly reduce the labor cost when harvesting yam and we will better protect its integrity when harvesting yam.

[0003] Nowadays, there are almost no machines for harvesting yam in China. Most of them hire people to harvest, and there are very few who use excavators to dig the soil first and then rely on people to dig out the yam from the soil. These machines have disadvantages. One of them is that the integrity of the yam cannot be guaranteed. Some mechanical equipment abroad exposes the yam by loosening the soil and harvesting it manually. Its disadvantages are also the same. It cannot guarantee the integrity of the yam and consumes labor costs. At this time, we need an automated harvesting equipment that can quickly harvest the yam while ensuring the integrity of the yam, and collect the yam in a centralized manner without consuming too high labor costs.
