Description

Technical Field

[0001] The invention relates to the technical field of yam digging, in particular to a yam digging and harvesting device. Background Art

[0002] Yam, a Chinese medicinal herb, is the tuber of the Dioscorea plant, Dioscorea zingiberensis. It is harvested between November and December, the root tip removed, the soil cleaned, the skin scraped off with a bamboo knife, and then sun-dried or oven-baked to create "hair yam." Select large, thick hairy yams, soak them in clean water, then slightly heat them and cover them with a quilt to keep them moist. Then, place them on a wooden board and rub them into a cylindrical shape. The ends are trimmed, dried, and polished to create "smooth yam." Yams need to be dug up when they reach maturity, and the yam is then processed and used.

[0003] At present, yam excavation is generally divided into manual excavation and machine excavation. Manual excavation can maintain the overall integrity of the yam as much as possible and avoid the yam from breaking, which will result in poor appearance in the later stage. However, manual excavation of yam is inefficient, which often increases the labor intensity of yam growers. When excavating yam by machine, the machine is too large, resulting in high cost during operation. In addition, the yam is easily broken during the process of machine excavation of the fan blades, which affects the later sales. Moreover, when the machine digs out the yam, the surface soil still needs to be cleaned manually. Therefore, machine excavation has limitations and is inconvenient to use. Summary of the Invention

[0029] During use, when it is necessary to dig yam, the track wheel 38 is first started by an external drive source, and the track wheel 38 moves as a whole through the base 20 and the equipment. When the equipment moves to the position where yam needs to be excavated, the hydraulic telescopic rod 24 is started by an external power source. The hydraulic telescopic rod 24 is recovered to drive the connecting plate 25 to descend. The connecting plate 25 is stably lowered by the sliding limit of the slide plate 26 and the second slide groove 22. At this time, when the connecting plate 25 descends, the cross plate 28 is driven to pass through the second moving port 23 and descend through the support rod 27. When the cross plate 28 descends, the fixed plate 30 is driven to descend through the connecting rod 29.
