JP2002315455A - Sphere float type valve for automatic water level control of paddy field - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide both a sphere float type valve for automatic water level control of paddy field and a suspension of a storage bag for a dissolved fertilizer with which irrigation water left in a wetland rice culture is controlled and toil of carrying and scattering a heavy fertilizer in a muddy rice field. SOLUTION: This sphere float type valve for automatic water level control of paddy field comprises only using buoyancy of sphere 1 of natural energy. This suspension of a storage bag for a dissolved fertilizer has a constitution that a suspension plate 6 having a cut 61 is nailed on the tops of two piles 5 as shown by the figure.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Remarks] 1. Utility model registration No. 3076134 2. A request for alteration of Utility Model Registration No. 3076142 was submitted as a patent application, so the present application was also a patent application.

[0002]

The present invention relates to a property for suspending a water level automatic control valve for a paddy field and a storage bag for fertilizer or the like completely dissolved in irrigation water in a U-shaped ditch for water intake.

[0003] Hereinafter, [1. Valve for automatic water level management of a spherical float type paddy field].

[0004]

2. Description of the Related Art Utility model registration No. 3076134 requires a float tube and a funnel, requires a thumbscrew and a plug, and is slightly more complicated and expensive than the present invention.

[0005] 2. Registered Utility Model Publication No. 305606 No. 3 3. Japanese Utility Model Application 10-6571 Practical application 2000-5092 5. Japanese Patent Application Laid-Open No. 2000-288064 * Since there was a call that there was no novelty, 6. Utility Model Registration No. 3076134 Utility Model Registration No. 3076142 * Although two applications were filed in the initial period, they are not described because they are complex.

SUMMARY OF THE INVENTION The present invention relates to automatic water level management, which is one of the greatest efforts in paddy rice management.

[0007]

SUMMARY OF THE INVENTION Circular bottle float ₁₁
Bonding the mandrel 2 holes 1 ₅ of the top 1 ₄ of the upper part of the funnel-shaped.

[0007]

[Examples and Functions and Effects of Each Part]

FIG. 2 shows a circular bottle float 1₁And funnel 1₂Bottom
1₄Diameter d, slope 1₃ Is large and the height of the round bottle is high
Height h1 and height h of the slope of the round bottle₂Is quite large
Large force, hole 1 on top of funnel₅Heart glued to the faucet 2
The tip of the rod 3 is the inner wall 5 of the water discharge pipe₂The above according to the displacement of the water level
It does not come off even if you drop it.

[0008] The full water level of the gap s ₁ is sensitive to full water level near Since the present invention property send a constantly a small amount of irrigation water close to殆Ndo 0 when the full water level height H ₁ has no Masa' part Hold and
In addition, since the gap s ₂ between the bottom H ₂ is large, the minimum water level is completely set to 0 immediately before rice transplanting, which requires a large amount of irrigation water at a time, and is also set to 0 when fertilizer is applied. Take the dissolved fertilizer, etc. into the irrigation water in the U-shaped ditch, and adjust by closing the appropriate number so that the water from several holes in the storage bag separately installed will disappear when filled with gum tape etc. according to the area of the field If a large amount of irrigation water flows in together, irrigation will take a long time,

Hereinafter,

FIG. 2 describes the [suspension device] of the storage bag shown in FIG.

[0015] risked cord 7 hanging between the upper end portions of the two piles 5 have denoted the incisions 6 ₁ prevent migration due wind plate 6
And [Suspension].

[Brief description of the drawings]

FIG. 1 is an example of the use of a spherical float, an explanatory side sectional view of the action,
It is a front view showing the composition of the suspension device of the storage bag of fertilizer etc. which were completely dissolved.

FIG. 2 is a front view of one back side of a storage bag for completely dissolved fertilizer and the like.
