生育しているレンコンを収穫することができる。 The lotus root digging machine of the present invention configured as described above operates the hydraulic cylinder 11 using the hydraulic pump 12 and the control lever 13 to pull up the arm 9 and the water pipe 14 fixed thereto to the position indicated by the chain line in FIG.
The traveling device 2 is driven to put the machine into a rice field where lotus roots are cultivated, one end of the hose is connected to the water intake port 4 of the pump 5, the other end is put into the irrigation canal, the pump 5 is operated, and the hydraulic cylinder 11 is turned on. The arm 9 and the water pipe 14 are actuated downward, and the spout pipe 1 is rotated downward.
7 facing a paddy field where lotus roots are cultivated as shown in FIG. 7, the machine is moved forward by the traveling device 2. Therefore, water from the irrigation canal pumped by the pump 5 is sent to the jet pipe 17 through the hose 16 and the water pipe 14, and is also sent between the peripheral wall of the jet pipe 17 and a conical core 18 disposed concentrically therein. The water flows through the annular outlet a formed between the conical core 18 and the lower end of the spouting pipe 17 and flows into the paddy field where lotus roots are cultivated, and the jet water flows underground. The soil around the lotus root is crushed from the top to the bottom of the lotus root, fluidizing it and pushing it backwards.Since the lotus root has a light specific gravity, it floats above the soil above the water surface, so the worker can
By collecting the lotus roots, you can successively harvest the lotus roots growing underground in this way.

れないで数個の節が連なつている状態で浮上させ
ることと、また、レンコンの肌が噴流水や流動化
される土壌で汚損されて変色しないようにするこ
とが肝要である。 In order to improve the quality of the lotus root that floats to the surface of the water, it is necessary to float the lotus root in a state where several nodes are connected without breaking at the joints, and also to make the skin of the lotus root It is important to avoid discoloration due to contamination with water or the soil being fluidized.
このためにはできるだけ低い水圧の噴流水を噴
出管１７の吐出口ａから噴出させることが必要で

る必要が生じる。 For this purpose, it is necessary to jet water with the lowest possible water pressure from the outlet a of the jet pipe 17, but the water pressure of the jet water may be adjusted depending on the soil quality and the depth of the place where the lotus root grows underground. It becomes necessary to adjust the amount.
レンコンが栽培されている水田の土質が砂質土

の水圧を低くして砂質土壌を円滑に流動化してレ
ンコンの損傷を防止することができる。 If the soil of the rice paddies where lotus roots are cultivated is sandy, the soil around the lotus roots tends to crumble, so low-pressure jet water is best.If the water pressure is high, the soil with large particles may damage the skin of the lotus roots. . Therefore, in this case, turn the handle 20 fixed to the upper end of the threaded rod of the core 18 concentrically arranged in the spout pipe 17 to the right, move the core 18 downward, and tighten the nut 19.
The cross-sectional area of the annular discharge port a formed between the core 18 and the lower end of the jet pipe 17 is shown in FIG.
As shown in FIG. 6, by making the jet water relatively large and lowering the water pressure of the discharged jet water, sandy soil can be smoothly fluidized and damage to the lotus roots can be prevented.

せることができる。 In addition, if the soil of the rice field where lotus roots are cultivated is clayey and the soil does not easily collapse due to the cohesive force of the clay, and if the pressure is reduced to break up the cohesive clay, the ejection pipe 1
Turn the handle 20 fixed to the upper end of the threaded rod of the core 18 concentrically arranged in the inner tube 7 to the left, move the core 18 upward, and tighten it with the nut 19. As shown in Figures 3 and 4, the cross-sectional area of the annular discharge port a formed between the and can make lotus roots float to the surface of the water.

ンコンを容易に堀取ることができる。 Next, the jet of water must reach the place where the lotus root grows underground, so if the lotus root grows deep below the ground, the jet water will have a higher water pressure than if it grows shallower than the ground. Although water is required, the present invention adjusts the water pressure of the jet water as described above to properly spray the jet water to the place where the lotus roots are growing underground, making it easy to dig up the lotus roots. .
