Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dispersion pipe, particularly a dispersion pipe for pesticides, fertilizers, and seeds that can be suitably used for dispersing granular pesticides, fertilizers, etc., and sowing seeds.

BACKGROUND OF THE INVENTION Conventionally, as a fertilizer application or seeding device, those shown in FIGS. 1 and 2, for example, are known.

In other words, 1 is a backpack-type container for storing fertilizer or seeds, etc., 2 is a backpack belt, and 3
1 is a bellows-shaped discharge pipe connected to the bottom of the container, 4 is a dispersion pipe detachably connected thereto, 5 is a flat dispersion nozzle member detachably connected thereto, and 6 is a spray amount provided in the dispersion pipe. The adjustment plate 7 is a handle for rotating it from outside the pipe, and 7a is a fixing nut, which controls the flow rate of the sprayed material from the container 1 through the discharge pipe 3 and the spray pipe 4 to the spray nozzle member 5. By adjusting by operating the adjustment plate 6, holding the dispersing pipe 4 and swinging the nozzle member 5 evenly, the material to be sprayed can be sprayed from the slit 5a of the nozzle member 5 to the left and right or to the front.

In the fertilizer applicator or seeding device configured as described above, the dispersion pipe 4 having the adjustment plate 6 is designed to be suitable for dispersing granular fertilizer or seeds, which usually have a diameter of several millimeters.

However, among agricultural chemicals, herbicides etc.
The herbicide is sprayed in the form of fine particles of 0.1 mm, and the appropriate spray amount for rice fields is approximately 3.5 mm.
Kg/10a, and approximately 5.0Kg/10a for upland fields, so it is extremely difficult to uniformly spray a predetermined amount using the adjustment mechanism of the spray pipe with the adjustment plate.

Therefore, when spraying fine pesticides such as the herbicides mentioned above, it is necessary to spray them directly by hand, or
Alternatively, at present, a specially designed and manufactured special machine is used to spray the above-mentioned material.

However, since herbicides are toxic, there is a serious problem when hand-seeding them because they have an adverse effect on the human body and are not good for hygiene.On the other hand, when using special-purpose machines, they are generally expensive and complicated to operate. As a result, there is a problem in that dispersion cannot be performed easily.

This invention relates to a spraying pipe that solves the above problems, and more specifically, it can be applied to a wide range of materials, from relatively large particles to fine particles, using a single fertilizing and seeding device, and can be applied over a fixed area. The object of the present invention is to provide a dispersion pipe for a fertilizing/seeding device that can uniformly and reliably spray a predetermined amount of fertilizer.

Hereinafter, the present invention will be explained in detail based on the drawings showing an example of its implementation.

In Figures 3 to 8, A is a dispersion pipe;
4 is a dispersion pipe, 5 is a dispersion nozzle member, 6 is an adjustment plate,
7 is an operating handle, and 7a is a fixing nut.

The dispersion tube fitting A includes two circular substrates 8 and 9 that can be fitted into opposing portions of the dispersion tube 4 with a required interval in the tube axis direction.
and a pipe body 10 that connects both boards 8 and 9 at an eccentric position and opens to the outside of both boards, and a front face of the board 8 on the tip side, and is connected by its central bolt shaft 11 and nut 12. Consisting of circular diameter flow control plates 13 that are rotatably stacked on top of each other,
The flow rate control plate 13 is provided with an outlet 13a having the same diameter as the pipe body 10 and several outlet ports 13b, 13c, and 13d with diameters successively smaller than the outlet 13a. By rotating the control plate 13, one of the discharge ports can be aligned with the pipe opening of the tube body 10.

In addition, in the present invention, it is preferable that the opening end surface of the substrate 9 on the inner rear end side (container container side) of the substrate in the dispersion tube A is formed into a conical shape. Transfer to the body 10 can be performed more reliably and easily.

Further, the base plate 9 on the rear end side may be provided with a two-pronged clamping member 14 as shown by the dashed line in FIGS. 7 and 8, as shown in FIG. It has the advantage that it can be held more reliably when inserted into the dispersion pipe having the plate 6.

Furthermore, one or more notches of arbitrary shapes may be suitably formed on the peripheral edges of the front and rear substrates 8, 9 and the flow rate control plate 13. This notch is useful for removing particles remaining in the container when, for example, fine particles are to be dispersed after being used for dispersing relatively large particles.

When distributing fine spray materials using the dispersion tube device configured as described above, Figs.
As shown in the figure, the dispersing tube fitting A is inserted into the dispersing pipe 4 to carry out the dispersing operation.

At this time, if the dispersion pipe has an adjustment plate 6, the adjustment plate 6 inside the dispersion pipe 4 is set to the fully open angular position, and the bifurcated elastic clamping member 14 on the dispersion pipe side is held between it. Hold it firmly so that it does not move. Moreover, before inserting the dispersion pipe fitting A into the dispersion pipe 4, the flow rate control plate 13 is rotated to select a desired outlet among the outlets 13a to 13d into the pipe body 10.
Adjust the angle to match the pipe opening.

When the spraying work is performed as described above, the fine particles that flow from the container 1 through the discharge pipe 3 into the spray pipe 4 are blocked by the front plate 9, and the pipe opening of the pipe body 10 opening there. After passing through the tube body 10, the flow rate is limited by the flow rate flowing into the tube body 10, and then from the tube port on the side of the substrate 8,
It exits from the outlet of the flow rate control plate 13 that matches this, reaches the spray nozzle member 5, and is sprayed from this nozzle in the front and left and right directions. In that case, by selecting the outlet ports 13a to 13d of the flow rate control plate 13 that are matched with the tube ports opening in the substrate 8, the amount of the dispersion discharged from the tube ports can be freely adjusted.

Next, when spraying a material with a large particle size, take out the spray pipe A and use only the spray pipe 4, as shown in FIG. Do it by operation.

It should be noted that a container of the type shown in FIG. 9 is convenient for spraying pesticides and the like that have small particle diameters and require a relatively small amount of spraying (per unit area).

Therefore, according to the dispersion pipe configured as described above, by incorporating the dispersion pipe A, it is possible to effectively and reliably disperse fine particles to be sprayed, and it is also possible to spray particles of large particle size. from,
The function as a spreading tool can be significantly improved.

Further, the dispersion pipe A can also be used by directly connecting it to the bellows discharge pipe 3.

As described above, according to the present invention, two circular substrates facing each other with a required interval are connected by a tube placed at an eccentric position, and the tube openings at both ends of the tube are connected to each substrate. A flow rate control plate rotatably held at the center of the board is superimposed on the front surface of the base plate, which is open to the outside of the tube and serves as the front end side. A dispersion pipe is provided in which a dispersion pipe fitting formed by an outlet and several outflow ports whose diameters are successively smaller than the outlet are opened on concentric arcs and is fitted into the inside of the pipe so as to be freely assembled. By using this spray tube, a single fertilizer seeding device can be used to control a wide range of materials, from large particles to fine grains, and to control the amount of application and achieve uniform spraying. Therefore, the function of the sprayer can be significantly improved.
