TECHNICAL FIELD

[0001] The present application belongs to the technical field of lotus root harvesting equipment, and particularly relates to a lotus root harvesting device. BACKGROUND

[0002] Lotus root is a very important aquatic vegetable in China, and has high economic value and nutritional value. Lotus root is a kind of agricultural product which is easy to grow but difficult to harvest. At present, lotus root harvesting is mainly completed by manual digging: one is shovel digging, which drains the pond water and uses a lotus root shovel to dig in the mud; the other is a water gun type, which uses a high-pressure water gun to flush the lotus root out of the mud in the water. The manual harvesting method has the characteristics of high cost and low efficiency, and due to the particularly harsh working environment and excessive labor intensity, it leads to low harvesting rate and serious damage to the lotus root.

[0003] The water gun type harvesting device in the prior art can only spray water vertically downward, which can flush away the silt around the lotus root, but the silt directly below the lotus root cannot be impacted by the water flow. After the silt around the lotus root is flushed away, the lotus root still cannot float, and it needs to be manually lifted to make the lotus root float.

[0004] In summary, the lotus root harvesting device in the prior art cannot impact the silt directly below the lotus root, causing the problem that the lotus root cannot float after being flushed by the water flow. SUMMARY
