Definitions

  • the present invention regards a device for distributing granular feed measures in fish tanks, according to the preamble of the independent claim.
  • the present device is inserted in the field of production of apparatuses for feeding aquatic animals, in particular fish, which live inside aquarium tanks.
  • the present device is intended to be advantageously used for distributing granular feed in aquarium fish tanks of various size, in particular aquariums having tens of tanks (e.g. employed commercially) up to aquariums having thousands of tanks (e.g. employed scientifically).
  • the present device is preferably employable for distributing granular feed measures in fish tanks that each have several liter capacity, e.g. 0.5-15 liters.
  • aquariums - in particular scientific aquariums employed in research centers - comprise a plurality of tanks (e.g. from several dozen to several thousand) in which fish are bred.
  • each tank has a capacity of several liters (e.g. 1-3 liters) and houses, at its interior, a maximum number of fish of about ten fish per liter.
  • Aquarium tanks are normally mounted on vertical support structures and are organized into multiple vertical columns arranged side-by-side each other.
  • the operator in order to administer the feed, the operator must with one hand sustain a container of powder feed having different chemical compositions and grain sizes in accordance with the needs and species of fish that must be feed. With the free hand, and generally wearing protective gloves, the operator picks up a small amount of feed, in particular a quantity deemed sufficient for the number of fish contained in the tank, calculated according to the experience of the operator himself/herself. With the back of the same hand that retains the measure of feed, the operator lifts the cover of the tank and releases the feed measure into the water.
  • the abovementioned feed administration operations involve various drawbacks in practice.
  • a first drawback consists of the fact that the administration of feed is affected by serious metering imprecisions, due to the variable sensitivity of different operators, and such sensitivity is even more reduced with the use of gloves. Consequently, the operator can administer feed quantities which can be greater than or less than the correct measure, with consequent undesired variations of the food and vital habits for the fish.
  • a further drawback of the abovementioned feed administration operations consists of the fact that such operations are not very hygienic, in particular causing the accumulation of organic waste at the tanks and on the covers thereof, after for example the accidental release of feed outside the tank. This involves high costs and considerable maintenance times for maintaining the environment of the aquarium clean and preventing the proliferation of fungi, bacteria and the like.
  • a further drawback of the aforesaid feed operations is due to the fact that such operations are not very practical for the operator, since he/she must operate with both hands engaged and above all he/she must also reach tanks arranged in high positions, with consequent tiring and risk of falling in repeating the operation many times.
  • a further drawback of the aforesaid feed operations is due to the fact that such operations require very high execution times.
  • such apparatus of known type comprises a support framework which is provided with multiple vertical support columns which sustain a horizontal beam, and is intended to be arranged in front of the tanks organized, as stated above, in multiple columns side-by-side each other.
  • the apparatus comprises an automated trolley which is slidably mounted on the horizontal beam of the support framework and bears a vertical rail fixed thereto.
  • the apparatus also comprises a dispensing device slidably mounted on the vertical rail of the trolley and adapted to dispense a quantity of feed in each tank.
  • the apparatus comprises a programmable control unit in operation connected to the trolley and to the dispensing device and adapted to drive the movement of the latter to allow the dispensing device to be arranged at each tank where it is necessary to administer the feed.
  • the dispensing device is provided with a feed container provided with an element for measuring the picked-up food, and with an actuation member connected to the container and drivable to rotate the latter, allowing the pouring of a predetermined measure of food within the tank.
  • a first drawback is due to the fact that the aforesaid apparatus of known type is very costly, requiring in particular investments of many tens of thousands of Euros.
  • a further drawback is due to the fact that the apparatus described in the patent US 2010/0313813 has a very complex structure and requires long and complicated maintenance operations.
  • the patent US 2,570,004 describes a device of known type for injecting powder chemical products into furnaces, in order to prevent the formation of unburnt residues. More in detail, such device comprises a tubular body which is connected to a funnel for feeding the chemical products and is provided with an injector of pressurized air adapted to suction, via Venturi effect, the chemical products from the funnel and to continuously dispense them through an injection point.
  • the patent DE 805207 describes a device of known type for dispensing paints provided with a feeding funnel connected to a distribution tube connected to a pressurized air source in order to continuously dispense the paint through an emission nozzle.
  • Further object of the present invention is to provide a device for distributing granular feed measures in fish tanks which prevents the accidental pouring of powder feed outside the tanks.
  • Further object of the present invention is to provide a device for distributing granular feed measures in fish tanks which does not require high maintenance.
  • FIG. 1 shows a side view of the device for distributing granular feed measures in fish tanks according to the present invention
  • FIG. 2 shows a side section view of the present device, in accordance with a first embodiment of the present invention
  • - figure 3 shows a side view, partially in section, of a detail of the device illustrated in figure 2, relative to a support body of the device itself
  • - figure 4 shows a side view, partially in section, of a further detail of the device illustrated in figure 2, relative to an adjustment body of a dispensing nozzle of the device itself;
