Description

The invention relates to an apparatus for spreading

  automatic dosing of granular fertilizers, this apparatus com-

  a reservoir, a measuring device, a measuring device

  charging, a drive motor and usual accessories.

  The controlled treatment of plants with granular fertilizers is often unsatisfactory. This is how appliances built for the treatment of large surfaces

  for reasons of space, it is not appropriate to

  many farms or, since small areas of land have to be treated, these

too expensive.

  Spoons or dosing bags, often used

  for small areas, on the other hand,

  deny that this kind of spreading requires extraordinary time-

  long, because it is necessary for each plant to draw and dose the fertilizer or product again, so that, in addition,

  contact with this fertilizer is inevitable. Another disadvantage

  heavy weight lies in the fact that plants with

  a dense and moist state, and also

  its, absolutely can not be processed using these

  devices or they can only be

mediates leaves.

  There are also known devices in which the

  dosing of fertilizers is carried out from a low

  with a flexible plastic tube at the end.

  which is a metering element. The opening of this element is done manually by actuating a traction element, which releases the desired amount of fertilizer. So the use or service of these devices is very painful,

  asks the user to put a lot of effort into

  puts no automated application.

  The object of the invention is therefore to propose a

  automatic control which allows a metered application, saving energy and efforts, of granulated fertilizers to bring fertilizers to plants at any stage of development,

without contact with the user.

  The problem thus posed is solved thanks to a

  the nature described at the beginning and characterized by the fact that the tank is connected, via a filling tube, with a metering drum mounted so

  to be rotated and on which one or more of

  metering tubes having at one of their ends an opening, arranged in the direction of rotation, and comprising

  an opening at the other end with a key

  pet shutter movable and which opens during rotation of the drum by contact with a transverse bar, arranged transversely to the direction of movement of the tube

  metering device in a funnel-shaped container.

  Other advantageous features of the invention

  The invention consists in that a) the shutter valve of the metering tubes is in the form of a tongue, which is larger than the opening or the lumen of the metering tubes; b) the shut-off valve is mounted by means of a spring hinge on the opening of the dosing tubes; (c) the dosing tubes are mounted on the drum so that they can be replaced; (d) the metering tubes have a measuring cup that can be replaced

  e) on the dosing tubes is mounted. a year:

  smoothing or ferrule which can partially cover the opening

  rest in the direction of rotation; f) the axis of the drum is connected via a transmission device to a drive motor; and g) a flexible tubular member having a telescopic tube and a tundish is mounted on the container

funnel shape.

  The apparatus according to the invention makes it possible

  technically simple and automatic application of granular fertilizer on small areas of soil. he can

  therefore serve especially in so-called exploita-

  such as nurseries and ser-

  res, and it is remarkably well suited for post-treatment

  plants with fertilizers and nutrients.

  To this apparatus are therefore associated technical advantages

  which are not affected by the devices and appliances

naked.

  Other advantages also exist in an eco-friendly

  granules which, depending on the distance between

  up to 500%, by avoiding contact with the granules to be spread and the possibility of treating

  plants whose development state is the most dif-

  ficult. It should be noted also the relatively low weight, the uncomplicated instructions and the extraordinary

precision of the dosage.

  The apparatus according to the invention can also be associated with

  readily available to conventional automatic potting machines, so that the desired amount of pellets is

  added at the same time as each potting operation.

  It is also possible to combine the device with a

  metering drum and to use a common circuit of deli-

  as described above and characterized. In this case, a control chain of the driven drums can provide synchronous operation. This opens up the possibility of spreading without prior mixing of an applied granular fertilizer with other

  granular products, for example phytopharma-

  ceutical. It goes without saying that it is also possible advantageously to use, with the aid of the apparatus according to the invention,

the finished mixture of the granules.

  The new apparatus according to the invention is generally suitable for a metered spreading of all granular products, whether fine granules o :. coarse granules, which must not, however, exceed a diameter

max. 5 mm.

  As a metering drum, a container having a circular cross-section and advantageously consisting of an inert plastic material, for example a polymer of the polyvinyl chloride type, is advantageously suitable. The drum may have any capacity, but must not be

  exceed an optimum amount of filling of 250 g

  Nules. The drum is rotatably arranged

  and it is mounted on bearings in a protective container.

  The axis of the drum is connected, via a device

  transmission, the drive motor, for example

  a 6 volt electric motor powered by a battery.

  This engine is advantageously equipped with a regulator of the

  rotation speed and a switch or contactor with

  floors, which has the advantage of allowing. re-

  set the working speed to the desired values.

  The drum is further provided with a locking device

  meture, advantageously a screw lid, in which is

  advantageously arranged also the look.

  The drum wall has tapered openings

  These are intended for the assembly of small dosing tubes.

  The drum can advantageously be mounted in a

  transportable support frame, for example made of aluminum tube

  minium, and is then worn with straps or braces.

on the back.

  The metering tubes also consist, advantageously

  polyvinyl chloride polymer and they

  are mounted on the drum, for example by means of a thread

  ge, so that they can be replaced.

  The metering tubes are made in the form of tubes and have any size which naturally has to

  be chosen according to the size of the drum. The first

  the first opening, formed at one end in the direction of rotation of the drum, receives the granules during rotation; the second opening, at the other end, is used for spreading the granules received. This spreading is done after

  opening of the shut-off valve, which is actuated by

  tact of the protruding tongue with the crossbar of

  the funnel and then closes again automatically.

  By a suitable choice of the diaemeter of the first opening, it is easy to adjust the desired quantity of

  pellets delivered. Preliminary tests make it possible

  terminate the necessary diameters appropriately.

  A corresponding replacement of the metering tubes and the variation of the magnitudes of the opening thus make it possible to modify the zone or dosing range in an extremely short time. A particular advantage is that the apparatus can optionally be set for spreading

  fine or coarse granules of different sizes

  grain rents. A ring mounted on the metering tube at the height of the first opening is used for this purpose. This ring or ferrule may partially cover this opening and the

  reduce this, which is particularly important for the

pumping fine granules.

  It is also possible to perform a

  the metering speed by continuously adjusting the motor rotation speed in ranges of

  forty supplies per minute.

  The reservoir of the granules is connected by a filling tube to the metering drum. This tank may have any size, but it must advantageously, to avoid overloading the user, be realized only for a

  quantity of granules up to 8 kg.

  The funnel-shaped container mounted underneath

  of the measuring device is connected, via a

  Flexible tubular element, with a telescopic tube comprising a distributor, which makes it possible to apply to the plants

treated the desired dosed granule.

  The device thus described can finally, one reason of

  its low weight, to be used and transported extra-

  usually easy, which presents (the particular technical advantages.
