The coating device comprises an engine 2 mounted on the frame 1, the shaft 3 of which is provided with an additional shaft 6 connected to it by means of two sets of stepped pulleys 9 and 10, holding the container 8 for applying a protective coating. The protective coating device according to the invention comprises drive means, preferably of variable speed, telling the capacitance to move the planetary rotation about an axis parallel to this axis of rotation, and this planetary rotation prevents the retention of the coated products on the walls KB, where they are driven by a centripetal force, carried by the movement of the rotation of the container on it. Thus, the products to be coated no longer tend to rotate with the container. 2 hp f-ly, 1 silslSa: > & Gb. • ^ > & CJ

    The invention relates to devices for applying a protective coating, in particular for applying one or more uniform layers of protective substance to products such as seeds.
    The aim of the invention is to improve the quality of the coating by changing the speed of rotation of the capacitance around its axis and the speed of planetary rotation with the possibility of inverse direction. no rotation of capacitance.
    The drawing shows a coating device.
    The coating device comprises a drive motor 2 mounted on the base 1, which is the driving mechanism of the coating application device.
    ((The end of the drive rotating shaft 3 of the engine 2 is equipped with a bearing bracket 4 located T-shaped. One end of the bracket 4 is provided with a swinging body (gearbox) 5 in which the shaft 6 freely rotates parallel to the rotating shaft of the driving shaft 3 of engine 2 on the other the end of the support bracket 4 is placed eccentric 7.
    At the end of the shaft b, it is fixed to the central part of its base — one tank 8 for applying a protective coating. The bottom of the tank is flat and smoothly passes into the side walls.
    The drive device in the rotation of the shaft 6 consists of a system of pulleys 9, mounted on this shaft b in mechanical dependence with the second system of pulleys 10, cascade mounted on a stationary bed 1.
    The end of the bracket 4, opposite the rocking body 5, is provided with a supporting element 11 parallel to the rotating shaft 3 of the engine 2. At the end of the supporting element 11, an idler pulley 12 is fixed at the top of the tank 8, holding the drive belt 13 arranged around the top of the tank.
    The device can be equipped with such an electroregulator as a rotating motor, the rotational speed of which can be adjusted from 25 to 250 rpm.
    The drive device rotates the shaft 6 and causes the rotational rotation in rotation around its own axis of rotation with a speed from 0 to 500 rpm. This speed depends on the speed of rotation reported by the electroregulator to the movable pulley 9 with a diameter of D2 and from Di to the fixed pulley 10. The speed of rotational movement is calculated from among 1 revolutions of the capacitance around
    own axis of rotation for a given period of time. In the case when the difference in diameters of the pulleys 9 and 10 is not great, the speed of the rotational movement of the capacitance around its own axis of rotation can be calculated according to the formula
    , D2-Di С
    the speed of movement of the planetar D2
    full rotation.
    In the proposed device for coating, the eccentricity between the axis of the rotating drive shaft 3 and the shaft of the shaft 6, on which the coating tank is installed, is smaller than the internal
    the radius of the opening of the container, which makes it possible to place the loading hopper 14 located along the axis of the rotating shaft 3 above the container. This stationary power supply device allows the introduction of covering
    substances in the course of the operation, do not stop the rotational movement, and / or inject a binding agent or glue through a fixed device;
    A variant of the proposed coating device is possible, where the eccentricity between the axis of the drive shaft 3 and the axis of the shaft b, on which the coating container is installed, is greater than the outer radius of the container.
    This embodiment makes it possible to equip the device with several application-coating tanks operating simultaneously. So. for example, you can replace the eccentric 7 with a container that is identical
    capacity 8, i.e. placed symmetrically to the first tank relative to the axis of the drive shaft 3.
    The coating apparatus covers various products, such as kernels, seeds, granules, fruits, confectionery products, dragees, almonds, pills, candies, pharmaceutical products, etc.
    The coater also allows seeds to be coated with substances such as nutrients. fillers, fungicides, herbicides, insecticides, etc., to coat the seeds for improved performance.
    germination, to apply various additives that can be included at any time of plant formation and growth in seed protection, as well as to give the seeds a shape or size that is well matched to automatic sowing.
    The device makes it possible to obtain a coating resistant to abrasion, friction, and impact. The strength of the coating depends on the type of coating product (binder or adhesive used) and on the speed of the centrifugal force acting on the contents of the applied container and the coating. So, the more centrifugal force, i.e. the greater the speed of rotation of the container, the more compact and stronger is the coating to abrasion. High velocities can be used in the device, and the products to be coated are not retained on the vessel wall, since they are also subjected to force as a result of planetary rotation, which peels them from this wall and causes them to fall, rotating, one on another.
    Example. The coating device (drawing) is provided with a 25-liter container 8 having a flat bottom that smoothly passes into the side wall.
    The container 8 is made of stainless steel and has a diameter of 370 mm and a height of 285 mm. The diameter D2 of the rolling pulley is 9,52 mm, the diameter Pi of the fixed pulley is 10.57 mm. The eccentricity 7 between the shaft carrying the coating container and the drive shaft 3 is up to 110 mm and is smaller than the radius of the container.
    200 tons of seed beets are dedusted, then moistened with an aqueous solution (50% solution of the following composition A) at the rate of 12 ml of solution per 100 g of seed. Wet seeds are placed in the stopped coating container 8. The entire coating system is then inclined at a 40 ° angle relative to the vertical.
    Planetary rotation speed of 100 rpm. The speed of rotational movement of the capacitance around its own axis of rotation. 10 rpm
    The directions of the rotational movements are opposite.
    When the container is rotated, 900 g of mineral additives containing crushed peat, bentonite, kaolin, and limestone are successively introduced into the loading hopper 14 by three sprays. 880 ml of an aqueous solution of the adhesive (composition A, including 42 g of polyvinylpyrrolidone, 126 gsahara and 1832 g of demineralized water). 48 g of a coloring agent (90% talc and 10% iron oxide) are then added.
    These operations take about 3 hours.
    Then the seeds are dried in a drying unit at 35 ° C for 16 hours. The seeds thus obtained are ready for use, they are the same size and there is no need to sift them, 34% of the covered seeds have a diameter of from 4 to 4.75 mm, and 66% -3.4 to 4 mm. Loss of se
    during processing, no one was found; in particular, not one of these seeds was damaged during the coating process.
    The germination tests carried out thereafter at 20–22 ° C on filter paper and wet sand gave positive results: 98% of the seeds germinated.
    EXAMPLE 2 A device with a 10-liter capacity having an ellipsoidal shape is used, the size of the major axis is 270 mm, the size of the minor axis 160 mm. Capacity is made of plastic.
    The diameters of the pulleys and the eccentricity between the axis of the shaft carrying the container and the axis of the rotating shaft are identical to those in Example 1.
    The coating device is inclined at an angle of 45 relative to the vertical.
    5 g of lettuce seeds are dedusted, then moistened with an aqueous solution (50% solution of composition A) at the rate of 12 ml of solution per 100 g of seeds.
    Planetary rotation speed of 90 rpm. The speed of rotational movement of the tank around its own axis of rotation is 9 rpm.
    The directions of the rotational movements are opposite.
    Then wet seeds are placed in a stopped container.
    In the process of rotating the container, 28 g of mineral additives, including clarcel, kaolin and silicon, are introduced through the loading hopper 14. A glue agent (14 ml), which is identical in composition to Example 1, is sprayed evenly during the coating process. Then 2 g of kaolin is added to polish the coating.
    These operations last for about 2 hours. After coating, the seeds are dried at ambient temperature with air supplied by a fan.
    The covered seeds are left to germinate in moist earth. Germination tests were carried out at about 20 ° C. These tests gave positive results (100% germination).
    In all cases, the coating adhered very well to the seeds and did not peel off either during conditioning or when using seeds, i.e. neither brittleness nor crumbling of the coating was observed.
    The resulting coated lettuce seeds were the same size. Examples of Zi4. It was carried out as in Example 2, but instead of seeds of lettuce, seeds of chicory and tomatoes were covered.
    Germination tests gave positive results (90-100% germination).
    The obtained coated seeds had the same size and spherical shape, which is about 6,500 tons.
