を提供しようとするものである。A well-known lotus root excavator is equipped with a pump mounted on a machine that can move over wet fields where lotus roots are cultivated, and pressurizes the water sucked up by the pump and sends it to the top soil of lotus roots through a nozzle. There is one that uses water pressure to remove the muddy top soil, exposing the lotus root and digging it out. The water pressure sprayed from the nozzle is 1 to 2 kll/cta2, and if this water pressure is sprayed onto exposed lotus roots, the lotus roots may break or buds may be lost, reducing the product value. was there. If this water pressure is lowered, the mud removal efficiency will be reduced, so a water pressure higher than a predetermined pressure is required. [Problems to be solved by 1 Ming] Therefore, the present invention maintains the water pressure sprayed from the nozzle at a level sufficient to remove the top soil of the lotus root, and mixes air into the sprayed water at the nozzle part. This will generate bubbles and soften the pressure acting on the lotus root, damaging the lotus root itself and the buds.
It is an object of the present invention to provide a jet water nozzle for a lotus root excavator which avoids the above problems.

た、芽を欠いたり傷つけたりすることがない。In order to achieve this objective, the present invention includes a pump mounted on a machine that can move over wet fields where lotus root is cultivated.
In this lotus root excavator, the water sucked up by this pump is pressurized and poured onto the soil above the lotus root through a nozzle, and the soil is removed by water pressure 9. The lotus root is exposed and excavated in step 9. At the tip of the nozzle, one end of the air suction tube faces the center of the nozzle and the other end protrudes outside the nozzle, and the negative pressure of the jet water jetted from the nozzle draws in outside air from the air suction tube, creating a jet stream. It is characterized by being configured to generate bubbles in water. [Embodiment] ``Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 indicates the body of a lotus root excavator;
The engine 2 is mounted in the front part, and a pair of running wheels 3, 3 (one not shown) is mounted on both left and right sides of the center part, and a transmission case 4 is mounted on the free transmission case 4, which is pivoted to the vehicle body 1 by a pivot 48 at one end. It is pivotally supported at the end and can be moved up and down by rotation of the transmission case 4. The wheel 3 has a wide left and right width, and has lugs formed around the periphery to increase the bearing capacity of the ground. Also,
A pump section 5 is provided from the center to the rear of the vehicle body 1.
The suction pipe (not shown) of this pump extends downward from the vehicle body 1 and sucks water from the lotus root cultivation, and the discharge pipe 6 is supported by a discharge pipe support member 7 and extends downward from the vehicle body 1. The nozzle 8 according to the present invention is attached to the tip of the nozzle 8, which is long and has a downwardly bent tip. In addition, the steering handle 9 of the vehicle body extends long rearward and is provided almost parallel to the discharge pipe 6 and the discharge pipe support member 7, and the rear end of the handle 9 is slightly The discharge pipe 6 is located at the rear, and the discharge pipe 6 is disposed closer to the left and right sides of the handle 9. A vehicle body 1 (on the DT side, center flows 1 to 10 similar to the well-known walking rice transplanter 8 and side floats 11 and 11 (one not shown) are installed. The nozzle 8 As shown in Fig. 2, its tip is constricted, one end faces the constriction, and the other end
An air suction pipe 12 is installed which projects outward from the pipe wall. The lotus root excavator constructed in this way is introduced into a paddy field (swamp, pond) where lotus roots are cultivated, and the center float 10 and side floats 11) are brought into contact with the mud, and the running wheels 3 are connected to the engine. The vehicle body 1 is rotated by the power from the vehicle body 2 and runs. The depth of the running wheels 3 from the vertical movement of the supporting floats 1o and ii is adjusted by the transmission case 4 depending on the depth and hardness of the mud. Then, the pump section 5 is driven by the power from the engine 2, sucks up water from its suction pipe, passes through the discharge pipe 1, and injects it from the nozzle 8. The pressure on the jet water jetted from the nozzle 8 is 1 to 2k (
The pressure is as high as 1/cm2, and the top soil of the lotus root is splashed off and removed by water pressure, exposing the lotus root. Outside air is sucked in through the pipe 12, mixed into the water jet, forms bubbles, and is ejected from the nozzle. This maintains enough pressure to blow away the top soil, but also removes the exposed lotus root (if it hits directly). The foam acts as a cushion so that the lotus roots do not break or damage the buds.The lotus roots exposed in the muddy soil by jet water are dug out manually, but this work is easy. Jet water ejected from the nozzle may be used to remove mud from the lotus root.The nozzle of the present invention is not limited to the lotus root excavator as in the above embodiment, but can also be used to add water pumped up by a pump. Any other type of excavation device that removes the top soil of lotus roots by pressing and spraying can be applied.
[Effects of the Invention] As explained above, according to the jet water nozzle of the lotus root excavator of the present invention, the air suction pipe 12 is installed at the tip of the nozzle 8 and at the end, so that it can be easily immersed in jet water. Air is inhaled to generate bubbles, and while maintaining the pressure necessary to blow away the soil above the lotus root, the bubbles act as a cushion even if this jet of water hits the exposed lotus root directly. It acts gently and won't break or damage the lotus root, or chip or damage the bud.
