Description

[Detailed explanation of the invention] Lotus roots are usually grown 20cm to 50cm underground in flooded rice fields.
The lotus root grows in 1.5 cm of soil, and in order to dig it up, a method is used that uses high-pressure water jets discharged from a pump to fluidize the soil in which the lotus root grows. There is. At this time, the source of the water sucked up by the pump is often water from flooded lotus fields, but there is an extremely large amount of suspended dust in the water from the lotus fields, and if only a regular strainer is used, the strainer will not be able to handle the strainer. The strainer often gets clogged, and we often have to stop digging the lotus roots and clean the strainer.

In order to eliminate these obstacles, we provide a water intake strainer for a water pump, which has a cylindrical body with a stationary frame and a number of water holes bored therein so that it can be placed horizontally at the end of the water intake hose of the water pump. .

The present invention will be explained below with reference to the drawings. Reference numeral 1 denotes a machine base of a traveling vehicle equipped with a running device for a track belt, and a water pump 2 is connected to its suction port 3 on one side of the machine base 1.
A support tube 4 is installed vertically in the center of the rear end of the machine base 1, and the front end of the water pipe support fitting 5 is installed at the upper and lower ends of the support tube 4. The front end of a water pipe 7, which is movably supported on a shaft and whose rear part is bent downward and has a jet water outlet 6 at its tip, is attached to the support metal fitting 5 by a tightening metal fitting 8. The main body of the lotus root excavator is constructed by connecting the front end opening and the discharge port 9 of the water pump 2 with a hose 10.

Reference numeral 12 is a water suction hose connected to the suction port 3 of the water pump 2, and a water intake port 11 is provided at the tip of the water suction hose.
2 is placed on one side of the aircraft outside with the water intake 11 facing rearward, and the water intake strainer 14 is a cylindrical body with numerous water holes 13 bored behind the water intake 11.
and connect its front end opening to the water intake port 11,
A water intake strainer for a water pump is constructed by fixing a water intake strainer 14 to a stationary frame 15.

Since the present invention has the above-mentioned configuration, when the water pump 2 of the lotus root excavator is operated, water from the lotus root field flows through the numerous water holes 13 of the water intake strainer 14, the water intake 11, the water suction hose 12, and the water pump 2. Then, from the discharge port 9 of the pump 2, through the hose 10 and the water pipe 7, the jet water is discharged from the jet water discharge port 6 into the lotus root field as high-pressure jet water, and this high-pressure jet water causes the lotus root to grow in the lotus root field. It is possible to dig up lotus roots by fluidizing the soil. At this time, since the cylindrical water intake strainer 14 is placed horizontally by the fixed frame 15 on the surface b of the soil where the lotus roots are growing, as the high-pressure jet water is discharged, the soil on the lower surface of the fixed frame 15 The soil surface on the lower surface of the stationary frame 15 forms a concave portion indicated by the dotted line e, and the strainer 14 is supported by the stationary frame 15 and buried below the soil surface b. The water puddle below the strainer 14 becomes deeper and the water absorption efficiency improves, and the dust c floating near the water surface a is not sucked into the strainer 14. In addition, even when the water depth d is relatively shallow, there is no need for air to be sucked into the strainer, so high-pressure jet water is discharged without interruption, and the lotus root digging work can proceed efficiently without interruption. be.
