Description

Description: TECHNICAL FIELD The present invention relates to a liquefied fertilizer application apparatus for solid fertilizer for streamlining fertilization and labor saving in paddy rice cultivation.

(Prior art) Many fertilizers that are conventionally applied to paddy fields are fixed fertilizers in the form of granules or powders, and at the present time, liquid fertilizers are sometimes administered. However, it is expensive and difficult to calculate the application rate. Since it has little experience and is not generalized, on the other hand, solid fertilizer has abundant experience in fertilizing effect and application amount per hit,
As a means for eliminating heavy labor and uneven fertilizing effect, a powder feeder for liquids (Jitsuko 45-8660) has been proposed.
Since the device flows out into the field in a semi-liquefied state, the fertilized state is not uniform, the related techniques of concentration adjustment and complete liquefaction are not solved, and there are drawbacks such as not being able to follow the water depth in the water channel.

(Problems to be Solved by the Invention) In view of the above circumstances, the present invention provides a liquefaction and fertilizer application apparatus for solid fertilizer, which is capable of completely liquefying an experienced solid fertilizer to rationalize and save labor.

(Means for Solving Problems) The solid fertilizer liquefying and fertilizing apparatus of the present invention is a liquefying apparatus for liquefying solid fertilizer in a guide cylinder by immersing a guide cylinder hung on the bottom surface of a hopper in a running water channel. The cylinder is made into a multi-layered cylinder so that it can be expanded and contracted up and down, and a required inlet is formed on a half peripheral surface facing the flowing water above the flowing water immersion area of the guide cylinder, and a required outlet is formed on the entire peripheral surface below. A ring having a variable opening degree is externally fitted to the opening surface of the outflow port, and a liquefaction space is provided in the lower part of the guide cylinder, and a liquefaction tank including the liquefaction space up to the inflow port is provided. It is made up of packaging.

(Operation) The guide tube follows the water level condition of the running water channel, and the solid fertilizer is semi-liquefied and automatically settles by the inlet and the lower outlet that take in the running water in the upper part of the running water immersion area, and the ring is the fertilizer component. In the liquefaction tank, the semi-liquefied fertilizer is sufficiently stirred in the liquefaction space with running water to completely liquefy and diffuse into the running water channel.

(Embodiment) The present invention will be described with reference to an embodiment. A liquefied fertilizer apparatus a for solid fertilizer (hereinafter, simply referred to as the present apparatus a) is a hopper for feeding solid fertilizer in a granular or powder form as shown in FIG. At the bottom of 1, the inner cylinder side guide cylinder 2 among the double cylindrical guide cylinders 2 is attached so that the lower end of the outer cylinder side guide cylinder 2 is submerged to the required depth of the water channel. The guide cylinder 2 on the outer cylinder side is attached to the water channel wall, and an inflow port 3 as a semi-liquefying means is provided around the semi-circumferential surface of the submerged area. As shown in Figure 2,
As an outflow means for adjusting the outflow degree of the semi-liquefied fertilizer, a required number of outflow ports 4 are arranged and a ring 6 around which a required adjustment port 5 is provided is rotatably fitted to the outflow means. A support frame 8 for forming a liquefaction space 7 hangs down, and a mesh bag 9 is put on the outer circumference of the outer guide cylinder 2 so as to enclose the support frame 8 to the inflow port 3. The upper end of 9 is attached to the guide tube 2, and the running water channel is provided on both left and right bottom surfaces of the hopper 1.
It consists of 11 legs 10 for sitting on the shoulder of the road.

In the device a of the above embodiment, the leg 10 is seated on the shoulder of the flowing water channel 11 across the flowing water channel 11, and the outer guide tube 2 is vertically adjusted and fixed so that the inflow port 3 is submerged in the running water. The ring 6 is rotated based on the empirical values of the flow rate and the fertilizer application amount to set the numerical aperture (or the opening degree) of the outlet 4, and the required solid fertilizer is put into the hopper 1. The solid fertilizer to be input is the guide tube 2
Is packed to the bottom. Therefore, when the flowing water of a certain flow velocity flows in from the inflow port 3, it interferes with the semi-circular surface that is not open, the energy of the velocity is converted into potential energy, and the inside of the guide tube 2 up to the required height above the water surface. The solid fertilizer in is moist and tries to settle under its own weight. then,
When the space between the inflow port 3 and the outflow port 4 below the inflow port 3 is observed from the outflow port 4 side, the running water taken in from the inflow port 3 has potential energy within that distance (height). Since the energy commensurate with the potential energy is converted into velocity energy and flows out from the outlet 4 limited to the adjusting port 5, the wet solid fertilizer is gradually drawn along with the sedimentation phenomenon and flows out. The flowing water flowing in from the portion of the outlet 4 facing the flowing water is a liquid that disturbs the solid fertilizer with the energy of the flowing water and pushes it out from the outlet 4, and in this way, the liquefaction that can sequentially stir the semi-liquefied solid fertilizer. It is made to flow out to the space 7 (liquefaction area), and it is made to fully liquefy in the bag 9, and the liquefied fertilizer component diffuses from the mesh of the bag 9 to the running water channel 11, and is evenly spread from the mouth of the paddy field to the rice field. Is, 該肥 fuel components are uniformly adsorbed on the soil.

(Effects of the Invention) As described above, according to the present invention, since solid fertilizer can be completely liquefied and supplied to a paddy field by flowing water without specifying a flowing water channel, the solid fertilizer can be infiltrated into the soil at a uniform concentration. As a result, the fertilizing effect is leveled and the labor is greatly reduced, which contributes to the rationalization and labor saving of fertilizer application in agricultural management in large-scale paddy fields.
