Definitions

• the invention relates to a device for incrusting and pilling core-shaped materials.
• incrustation or pelleting is understood to mean the application of pesticides, fertilizers and neutral masses in layers to the individual seeds, these substances being liquid and / or powdery.
• the incrustation and pelleting is necessary to protect the seeds against plant and animal pests and to apply fertilizers.
• coating pans are used according to the prior art. These consist of a bowl-shaped mixing drum and a drive base. Depending on the size of the kettle, 15-50 kg of seed are filled into it, with the operator manually adding liquid and powder alternately.
• DE-OS 25 51 579 describes a device for coating seeds, which consists of a rotatable kettle, a supply air pipe that ends below the surface of the seeds contained in the kettle in a hole provided with holes, and one above the seeds in the kettle arranged exhaust air opening, wherein the head piece is assigned a blow line, which starts from a blower, is connected to an enveloping mass container.
• the known device is a rotationally symmetrical boiler, which is only suitable for batch operation, since there is no continuous inflow and outflow of the pelletized material, which is also not technically feasible for a boiler.
• the known device only has feed lines and storage containers for the pelletizing agents, but no metering devices. No metering device is provided for the seed feed either.
• DE-OS 30 33 433 describes a device for coating vegetable seeds, in which a type of screw conveyor is provided in a housing, which is connected on the inlet side to a feed hopper for the supply of the material to be treated, one immediately after the feed hopper or two spray nozzles for introducing liquid treatment agents into the initial area of the screw conveyor.
• a conveyor belt is provided at the end of the screw conveyor, and a so-called disagglomerator is arranged at the end of the conveyor.
• the incrustation and pelleting of granular materials cannot be carried out, and it is also not intended for this purpose.
• granular materials are coated in a screw conveyor. It is not possible to coat seeds in pill form with the known device.
• DE-OS 30 33 433 relates essentially to coating seeds with chemical substances that cause a delay in germination. This type of coating requires the subsequent dissolution of the agglomerated grains obtained.
• a device for incrusting and pilling grain-shaped materials with a metering device for supplying the grain-shaped material, in particular seeds, and several spray nozzles in that it has a drum, which is preferably polygonal and is lined on the inside with rubber or plastic, in which one or more spray nozzles connected to a metering pump, one or more powder application devices and one or more spray nozzles connected to a further metering pump are provided in succession.
• the powder application device preferably consists of a brush screw arranged on a tube extending from one end of the drum, the tube being powder-tight in the region of the spray nozzles and having a plurality of outlet slots arranged over its remaining length.
• the device for continuous incrustation and pilling has a drum 1, the product-contacting side of which is lined with rubber or plastic.
• a drum flow metered in weight or volume is fed continuously to the drum 1.
• a metering pump 3 is controlled via an electrical pulse, by means of which a continuously selectable amount of liquid is applied to the seed from a storage container 5 equipped with an agitator 4 via a line 6 and spray nozzles 7. Due to the continuous feed of seeds, an inevitable feed of the seeds occurs in the drum 1. As soon as the seed has passed the wetting path, powder (neutral pill mass, fertilizer, pesticide, etc.) is applied to the seed, again triggered by an impulse.
• the powder is fed from a storage container 8 to the actual powder application device by means of a screw conveyor 15.
• This consists of a tube 9 in which a brush screw 10 is arranged.
• the tube 9 has a plurality of outlet slots.
• the use of a brush screw 10 in a tube 9 with a large number of outlet slots arranged in tube length makes it possible to apply it uniformly and for a maximum of time.
• a certain section of the drum length is available for setting the powder with the liquid.
• the seed becomes the trom due to the coefficient of friction Melbeschickung and the formation of the drum 1 as a polygon always kept in rolling motion. This creates a uniform rolling up of the powdery substances on each individual seed core.
• the last area of drum 1 is wetted again. Dosage and application is done as in the first section.
• a storage container 12 provided with an agitator 11 is provided, from which 13 nozzles 14 supply liquid by means of a metering pump.
