Description
This invention relates to an apparatus suitable for supplying plants with treatment substances that can be dissolved in water - e.g. fertilizers, weed killers and the like, In the field of gardening and in agriculture the prob-lem frequently arises as to ho~ best to apply a fertilizer to the soil or distribute a plant protective or a weed killer on to a gardening or field area, both from the point of view of incur-- ring a minimum of work and from th~ point of view of minimizing costs.
With fertilizers in a dry form, up to now it has been usual to distri~ute the generally granular or powderlike material either manually or by automatic distributing means. This method has various serious disadvantages. As a result of the highly concentrated fertilizer in undissolved form, burning is easily caused especially with young plants since the distribution is generally rather irregular and accumulation of fertilizer in places cannot be avoided. Furthermore, the fertilizer is partly ; lost as a result of wind or for other reasons, or alternatively ; is distributed to the wrong areas so that an unnecessarily high consumption of fertilizer is incurred. Furthermore, the fertil-~.
izing effect is obtained only later on, as the dissolving of the fertilizer by water is required before it can be absorbed by the '.',J.
i`^S plants. In order to avoid the above disadvantages, apparatuses ; have been proposed wherein fertilizers and other materials for ~; treating the plants are introduced into pouring water. In one known embodiment, a rotating cage made of wire is provided in a ;s~ casing through which pouring water flows; the pouring water flows :;
partially around or partially through the cage in which the mat-erial is located~ However, the apparatus has considerable dis-3~ advantages since undissolved material passes through the inter-~ stices of the cage or container into the water flow, which .;, ~; 1 ~

~472S4 automatically results in a clogging of the nozzles of, for ex-ample, a sprinkler after a period of time. If one tries to ~, overcome this problem by making the interstices of the cage suf-ficiently small - i.e, smaller in diameter than the diameter of the vents of the sprinkler nozzle, then this will also result, after a period of time, in the interstices of the cage or con-tainer becoming clogged so that no material or an insufficient amount of material is mixed in with the pouring water. This is particularly true as fertilizers often include materials which are rather difficult to dissolve in water. Furthermore, the application of a precise dosage is not possible.
It is a general object of the invention to provide a new and improved apparatus for impregnating water flowing through a water conduit with desired ingredients or treatment substances such as fertilizers and/or plant protectives and/or weed killers prior to its discharge at the end of said conduit.
It is an object of the invention to provide an appara-,, .
tus preventing any undissolved particles of the ingredients from being carried along by the water flow.
"
According to this invention, there is provided an apparatus comprising a container, wherein the container provides ; a wall section, preferably an outer wall section, which is com-pletely closed externally, against which wall material which has , not yet been dissolved i5 pressed as a result of a centrifugal ::
force caused by rotational movement of the container. An open-ing in the area of the rotational axis and/or between said axis and the wall section at a sufficient distance from said wall section is provided so that material which has not yet been dis-solved cannot pass or discharge through the opening from the con-tainer. This invention is based on the general principle that in view of the different specific weights between the water and `' - 2 -1047%54 the material to be introduced into the~ater, and/or because of the effect of the flow conditions arising,onl~ such material that is completely dissolved in water can leave the container through the opening.
In a preferred embodiment of the apparatus, the con-tainer isFrovided with a first ace or bottom surface, which is closed and which extends transversely or perpendicularly to said wall section, and is also provided with a second face or upper wall which also extends transversely or perpendicularly to said - 10 ~all section.
Preferably a truncated surface joins the wall section of the container and, preferably in the second face or upper wall, at least one further opening is provided in addition to the central opening, which further opening is staggered radially with respect tG the central openlng.
These and other features and advantages of my invention wîll be more fully apparent from the following description, taken in connection with the accompanying drawings, wherein like refer-ence characters refer to the same or similar parts throughout the several views and in which:
FIGURE 1 shows a top view, partly in section, of an apparatus according to this invention; and FIGURE 2 shows a section through the apparatus along line I-I of Figure 1.
~`; In Figure 1, a cylindrical casing through which water flows, is provided with a water inlet pipe 2 and a water outlet pipe 3, which are appropriately connected to, for example, a - water supply and a sprinkler respectively. In the centre of the casing a pivot pin 5 is provided for supporting a container 6, which is rotatable around said pivot pin. All the parts of the casing are preferably made (water inlet and outlet pipes 2 and 3, pivot pin 5, etc.) as an integral unàt from plastic material.
For ease of production of the casing and in order to be able to easily remove the casing from the mould for proaucing such cas-ing, it is useful to produce at least part of the casing lateral wall 7 separately, and combine said part in a known manner such as b~ gluing, welding or the like with the remaining casing.
On its upper side the casing is provided with a cover 8 preferably made from a transparent material, which cover is seated with its downwardly directed outer rim on an internally drawn upper rim 10 of the casing at outer wall 7. By means of upper inwardly drawn rim 10 outer wall 7 also gets the required mechanical strength in order to withstand external forces.
'~ Container 6,in a manner similar to casing ~ is of a gen-erally cylindrical section and comprises an outer wall 11 which extends concentrically to pivot pin 5, which outer wall on the , one hand joins a bottom surface 12 and on the other hand joins a truncated surface 13. Bottom surface 12 is drawn inwardly for forming a bearing sleeve 14, which embraces pivot pin 5, where-by said sleeve 14 extends into a tip 15 in order to gain better flow conditions at a front surface thereofdirected towards the interior of the container.
The end of surface 13, which tapers towards rotational axis 16 of the container, forms an upper opening of the con-tainer which is closed by a cover 17 preferably made from trans-`; parent material. Container 6 and cover 17 are preferably made from plastic material.
Cover 17 is provided with a centre opening 18 and add~tional openings 19 arranged around said centre opening such that it is possible to adapt the number of additional openings 19 to the particular use and/or to vary their number.
In the illustrated embodiment, openings 19 can be closed either entirely or partly by providing, in addition to cover 17, a disc 17' on said cover, w~ich disc is rotata~le ; around a centre extension 20 and contacts cover 17. Prefer-ably, the disc is formed of a transparent material. Within said disc, openings 21 are provided which can be aligned with openings 19; said openings 21 can be aligned entirely or partly or not at all by rotating disc 17' around centre extension 20 of cover 17 with openings 19 so that, dependent on the position of the disc, a resulting openingis obtained within cover 17, the cross-section of which opening can be varied whereby the cross-section of said resulting opening is determined by the area across which openings 19 and 21 overlap each other.
; At the outer wall of container 6, blades 22 are formed;
blades 22 extend in an inclined direction in ~espect of the con-, tainer radius such that when the blades are hit by the water ~lowing through inlet pipe 2, they rotate container 6 in the direction of arrow A of Figure 1. By choosing the angle of in-clination of blades 22 in view of the container radius, the ro-tational speed of container 6 can be adjusted to the required value. Within inlet pipe 2 a check valve, which consists of a valve seat 23, a ball 24 and a sprin~ 25, is provided; spring 25 urges ball 24 towards spring seat 23. The use of a check valve .~ is preferred in order to prevent any dissolved material from ;~i passing from the apparatus into inlet pipe 2, which might other-wise occur if means were provided on a sprinkler connected to ;~ water outlet pipe 3 which allows interruption of the water stream.
In- order to operate the app~atus, initially cover 8 of the casing is opened and container 6 is removed from the casing.
Then cover 17 of the container is opened and the desired amount of material, such as fertilizer, plant protectives, weed killer , or the like, is placed in container 6. Subsequent thereto, 104'7ZS4 container 6 is closed again by means of cover 17, and disc 17' on cover 17 is adjusted in such a manner that openings 19 or 21 form a resulting opening, wh~c~ corresponds to the desired con-centration of material 26 within the pouring water. In order : to simplify the ad~ustment operation, a scale 27 is provided at opening 19 at which the pos~tion of an edge 28 of corresponding opening 21 can be read.
After having adjusted the resulting openings within container cover 17, casing 1 is closed again by means of cover 8 and the water is supplied to inlet pipe 2. By means of water flowing through casing 1 and through pipes 2 and 3, container 6 ? - as already described - is rotated in the direction of arrow A
of Figure 1 around pivot pin 5. This rotation causes material ; 26 within container 6, as a result of the centrifugal or rota-tional force acting upon substance 26, to be urged towards out-side wall 11, bottom surface 12 and truncated surface 13 in the manner shown in Figure 2. In other words,the rotational move-.. ment of container 6 generates a liquid flow, as shown by the flow line designated by reference numeral 27', whereby water enters the interior of container 6 through centre opening 18 within con-tainer cover 17 and discharges fro~ the container through open-ing 19. Simultaneously, a vortex flow as indicated by refer-ence numeral 28' is formed within the interior of the container which vortex flow dissolves material 26 and mixes partially with flow 27 in the interior of the container so that ~ssolved mat-: erial 26 passes through opening~19 into the water flow surround-. ing container 6 and is discharged through outlet pipe 3. The . amount of dissolved material 26 discharged from container 6 is, of course, determined by the intensity of flow 27' and by the dimensions of openings 19 or, alternatively, of the resulting openings which are formed b~ openings 19 and 21.
As can be seen from Figure 2, openings 19 and/or 21 ~047254 and centre opening 18 are spaced a sufficient distance from material 26, which is provided within container 6 and is not yet dissolved, or, in other words, from the corresponding container walls towards which the not yet dissolved material 26 is urged, thus only dissolved material will leave container 6 via flow 27' so that clogging of the nozzles of a sprinkler, with which the . apparatus is connected, by means of not dissolved or incom-pletely dissolved material is effectively prevented.
. The described apparatus preferably is supplied with a number of interchangeable containers 6 so that the user has the ~, possibility to use the same apparatus for mixing various mater-ials to the pouring water, whereby the containers including the various materials merely have to be interchanged. In view of the fact that covers 8 and 17 are made from transparent material, s it is easy to control the consumption of mater~al 26.
