Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment, and in particular to a nozzle fixing device for an automatic lotus root harvester on water. Background Technology

[0002] The high-pressure water flow lotus root harvester uses a high-pressure water pump to generate a high-pressure water flow that washes away the soil around the lotus root, loosening it. Then, a robotic arm or conveyor belt is used to harvest the lotus root, which can greatly shorten the lotus root harvesting cycle and improve harvesting efficiency.

[0003] Chinese Patent Publication No. CN 220776575 U discloses an amphibious integrated lotus root harvesting device, which includes a main frame, a hydraulic flushing mechanism, a collection mechanism, and a spiral wheel walking mechanism. The hydraulic flushing mechanism includes a connecting frame and a nozzle assembly. The connecting frame is inclined at the rear end of the main frame and its pitch angle is adjustable. The nozzle assembly is mounted on the connecting frame, and its position on the connecting frame is adjustable. The nozzle assembly is equipped with multiple nozzles. The collection mechanism includes a propeller, a conveyor belt, and a collection bag. Two propellers are located at the front end of the main frame. The water flow generated by the rotation of the two propellers carries the lotus roots onto the conveyor belt and then into the collection bag. Two spiral wheel walking mechanisms are symmetrically installed on the left and right sides of the main frame. The spiral wheel walking mechanisms enable the device to move in water and on land by changing the state of the spiral wheels. However, the nozzle assembly has a small range of motion and low flexibility, which seriously restricts the efficiency of lotus root harvesting. Utility Model Content
