Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in spray pipes, particularly spray pipes for pesticides, fertilizers, and seeds that can be suitably used for dispersing granular pesticides, fertilizers, etc., and sowing seeds. .

BACKGROUND ART Conventionally, as a fertilizer application or seeding device, those shown in FIGS. 1 and 3, for example, are known.

In other words, 1 is a backpack-type container for storing materials to be spread such as fertilizer or seeds, 2 is a backpack belt, 3 is a bellows-shaped discharge pipe connected to the bottom of the container, 4 is a dispersion pipe detachably connected to the container, and 5 is a flat spray nozzle member detachably connected thereto, 6 is a spray amount adjusting plate provided in the spray pipe, 7 is a handle for rotating it from outside the pipe, 7a is a fixing nut, By controlling the flow rate of the material to be sprayed from the container 1 to the spraying nozzle member 5 via the discharge pipe 3 and the spraying pipe 4 by operating the regulating plate 6, and by gripping the spraying pipe 4 and shaking the nozzle member 5 evenly. The material 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 usually has a
It is designed to be suitable for spreading granular fertilizers or seeds with 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 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 the machine operation is complicated. 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 purpose of this invention is to provide a spreading pipe for a fertilizer and seeding device that can uniformly and reliably spread a predetermined amount of fertilizer.

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

2, 4, and 5, 4 is a dispersion pipe, 5 is a dispersion nozzle member, 6 is an adjustment plate, and 7 is an operating handle, and the dispersion pipe A is assembled into the dispersion pipe 4. There is.

The dispersion pipe A includes a straight pipe body 8 having a diameter smaller than that of the dispersion pipe 4, a lug-shaped inlet pipe 9 fitted and connected to one end thereof, and a latch-shaped inflow pipe 9 fitted and connected to the other end of the pipe body 8. The outflow pipe 10 includes:
A screw hole 10a is provided at a required location as necessary, into which a flow rate adjusting screw member 12 is screwed, and an engagement groove 10b is provided at the tip edge of the outflow pipe 10 for the purpose described later. It is being

The outer diameter of the tip end of the flap-shaped inflow pipe 9 of the dispersion pipe A is equal to the inner diameter of the dispersion pipe 4, and the outer diameter of the tip of the flap-shaped outlet pipe 10 is smaller than the inner diameter of the spray pipe 4. The total length of the fitting is the length in the dispersion pipe 4 from the front part of the adjustment plate 6 to the distributing piece 5b with a diamond-shaped cross section provided in the dispersion nozzle member 5 through the tip port of the dispersion pipe 4. When the dispersion pipe fitting A is inserted into the dispersion pipe 4 and the dispersion nozzle member 5 is fitted to the distal end of the dispersion pipe, the engagement groove 10b of the outflow pipe 10 is aligned with the dispersion nozzle member 5. It is fitted into the distribution piece 5b so that positioning can be performed.

In addition, at the inlet of the truss-shaped inflow pipe 9,
A perforated plate 11 like a net plate is attached to its peripheral protrusion 11a.
It may be structured so that it can be attached and detached by fitting it into the receiving groove 9a of the inflow pipe 9. This prevents the pipe body 8 from being blocked by coarse particles contained in the spray material. In addition to being prevented, the third
If the spray pipe shown in the figure is used to spray relatively large particles, and then the spray pipe shown in Fig. 2 is used to spray, the particles remaining in the container may be This prevents the pipe body 8 from being blocked by large objects flowing out.

When spraying fine particles using the spray pipe configured as described above, as shown in Figs. I do.

When using the above-mentioned dispersion pipe A, the amount of liquid to be received into the dispersion pipe 4 is set in advance using the adjustment plate 6 of the dispersion pipe 4. Then, from the container 1 through the discharge pipe 3, the dispersion pipe 4
The fine dust that has flowed into the perforated plate 1 is first disposed at the inlet of the inflow pipe 9 provided as necessary.
1, the flow rate is arbitrarily adjusted and the passage of lumps and foreign matter is prevented, and from there it passes through the tube body 8 to the outflow tube 10, where the threaded member 12
The flow rate is adjusted by the flow path restriction portion.
The material to be sprayed coming out of the outflow pipe 10 is sprayed from the spray nozzle member 5 to the left and right and to the front.

In addition, when the particle size of pesticides such as herbicides is relatively small and the amount of spraying per unit area is generally small (about 1 to 10 kg/10 a), a slightly smaller container as shown in Figure 6 is used. It is considered suitable.

Next, when spraying large particle size particles,
Remove the dispersion pipe A and as shown in Fig. 3,
Only the spray pipe 4 is used, and the flow rate of the spray material is adjusted by operating the control plate 6.

According to the dispersion pipe for fertilizing and seeding equipment constructed as described above, by incorporating the dispersion pipe A, it is possible to effectively and reliably uniformly disperse fine particles to be sprayed, as well as to spread large-sized particles. Since it can also spray water, its function as a fertilizing and seeding device can be greatly 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, it has a straight tubular body, a lattice-shaped inflow pipe communicating with one end thereof, and a lattice-shaped outflow pipe communicating with the other end,
Furthermore, if necessary, a perforated plate is provided at the tip end of the inflow pipe, and a dispersion pipe fitting, which is provided with a flow rate adjustment mechanism operated by a screw member at a desired part of the outflow pipe, can be freely inserted and installed inside. A dispersion tube is provided. The spray pipe is equipped with a handle-operated flow rate adjustment plate that controls the spray amount, so by using this spray pipe, it is possible to spread from large particles to fine particles using a single fertilizing and seeding device. Since it is possible to control the amount of sprayed material and uniformly spray a wide range of materials, including objects, the function of the sprayer can be significantly improved.

Furthermore, the spray pipe according to the present invention is extremely hygienic because it can spray even toxic agricultural chemicals such as herbicides without touching the human body, does not require complicated operations, and is inexpensive. It has certain characteristics, and its practical value is extremely great.
