The working principle and the flow of the application are as follows:
when the device works in water, the spiral wheels 52 of the two spiral wheel travelling mechanisms 5 are in a lifting state, and the spiral wheels 52 are separated from contact with the ground at the moment, so that buoyancy is provided for the device; when the lotus roots need to be flushed, according to factors such as the ambient water depth, the hydraulic flushing mechanism 2 adjusts the pitching angle of the connecting frame 27 and the position of the nozzle assembly 21 on the connecting frame 27 through the electric push rod 25 and the stepping motor 26 respectively, so that the lotus roots are flushed at the optimal position, then the water pump 29 starts to work, and the spray head continuously sprays high-pressure water into the sludge to enable the lotus roots to float out of the sludge; the spiral wheel travelling mechanism 5 drives equipment to move in water to finish the scouring of lotus roots in the whole water area, so that the lotus roots float above the water surface; if more sludge is on the lotus root, the hydraulic flushing mechanism 2 reduces the water pressure or changes the spraying angle, and the water is sprayed to the lotus root to flush the sludge on the lotus root; when the lotus roots floating on the water surface are collected, the hydraulic flushing mechanism 2 stops working, and water flow generated by rotation of the two propellers 47 of the collecting mechanism 4 enables the lotus roots floating on the water surface to move towards the inside of the main body frame 1, when the lotus roots pass through the correcting wheels 48, the distance between the two correcting wheels 48 is smaller than the length of the lotus roots, the lotus roots cannot directly enter in the transverse direction, can only enter the conveying belt 44 in the length direction, and enter the collecting bag through the conveying belt 44, so that the collecting bag can collect more lotus roots; the distance between the two correction wheels is basically the same as the width of the conveying belt, so that a plurality of lotus roots can be accommodated at the same time, and the collection time is shortened. In addition, this equipment will wash out the lotus root and collect two movements of lotus root and separate, avoided the in-process of receiving while washing, high pressure efflux is continuous to spraying in water and is led to silt more around the lotus root, and when the lotus root was collected to the equipment, the condition that equipment was blockked up appears easily.
When lotus roots collect certain weight, the staff control equipment moves to the land, when the lotus roots reach the junction of the water area and the land, the spiral wheels 52 of the spiral wheel travelling mechanism 5 are switched from a lifting state to a descending state, so that the spiral wheels 52 are contacted with the ground, then the lotus roots continue to move, and after the lotus roots reach a designated place, the staff take off the collecting bag, so that the work of collecting the lotus roots once is completed; if the lotus roots in the water area are not completely collected, the device replaces an empty collecting bag and returns to the water area to be continuously collected, and when the lotus roots reach the junction of land and water area, the spiral wheels 52 of the spiral wheel travelling mechanism 5 are switched from a descending state to a lifting state, and then the collection work is continuously carried out in the water area.
