. materials on the surface. Material From the hopper 3 through the unloading window 5 by the feed mechanism 4, by transporting devices 6 through the material lines 16 are supplied to centrifugal spreading devices 12 mounted on the supporting bars 10 by means of guides 17 so that they can be moved along the supporting bars. Spreading devices 12 have a material receiver 13 and centrifugal disks 14 with a device 15 for their drive. Bearing bars 10 are attached to the frame 1 on the vertical ¹ hinge 9 and adjustable in height. Centrifugal spreading devices 12 in ', depending on the coefficient of sail material, freeing the locking devices 18, bring together so as to obtain an optimal area of mutual overlap and ensure uniform distribution of the material. 1 hp f-ly, 1 ill.

The invention relates to agricultural machinery and can be applied to soil ^; bulk fertilizers, including during the growing season of plants in the cultivation of crops on intensive technologies using tramlines, as well as for spreading sand, salt, crushed blast-furnace production and other materials.

The purpose of the invention is to improve the uniform distribution of the material on the surface.

The drawing shows the scattering of bulk materials, rear view.

The bulk materials spreader has a frame 1 with support wheels 2, on which a hopper 3 is installed to accommodate bulk material. The bunker is equipped with a material feed mechanism 4 to the unloading window 5, which is blocked by a metering valve. The material feed mechanism is driven from the tractor's power take-off shaft or from the support wheel. For forming material flows to the transporting devices 6, a divider 8 is installed in the discharge chute 7. The spreader frame is attached to the spreader frame by means of vertical hinges 9 height-adjustable support bars 10 located in working position across the direction of movement of the unit. Adjusting the height of bearing beams 10 is achieved by changing the length of the brace 11. At each carrying bar 10 is mounted a centrifugal spreader device 12 which has materialopriemnik 13, centrifugal wheels 14 with the device 15 to drive them _from the centrifugal disc drive may be performed, for example, a hydraulic motor and V-belt transmission. The material receiver is connected to the transporting device 6 with the help of the material pipeline 16 of variable length (for example, a telescopic pipeline). Centrifugal spreading devices 12 on the carrier bars 10 are installed by means of guides 17 with the ability to move along the carrier bars. Center position. the running spreading devices 12 on the supporting bars are fixed by locking devices 18. If necessary, removable self-aligning wheels (not shown) can be mounted on the outer ends of the supporting bars.

If the material has a low coefficient of windage, then particles, other things being equal, fly further from the disk axis of the centrifugal spreading device 12. For both sections of the established mutual movement of material scattering zones between the internal (relative to the longitudinal axis of the unit) centrifugal disks (to ensure uniform distribution of materials on the surface) the latter are installed with a center distance E, from each other. The material from the bunker 3 is fed by the feed mechanism 4 through the discharge window 5, which is blocked by the metering valve, and is sent to the discharge tray 7, where it is divided into two streams by a divider 8. The conveying devices 6 through the material lines 16 deliver the material to the material receivers 13 of the centrifugal spreading devices whose position on the supporting bars 10 fixed locking devices 18. The material centrifugal discs 14 is scattered over the surface.

If the material has a large coefficient of windage, then all other things being equal, its particles fall closer to the axis of the disk of the centrifugal spraying apparatus 12 and a strip is formed along the axis of movement of the aggregate with an insufficient specific density of material distribution over the surface or free of material. To eliminate the uneven distribution of the material, the centrifugal spreading devices 12, freeing the locking devices 18, are moved in the guides 17 along the supporting bars 10 to the longitudinal axis of movement of the unit (the position of the centrifugal spreading devices is indicated by a dashed line) until the center-to-center distance _{2 2} between the inner centrifugal disks 14, At This makes the specific distribution density of the material over the surface.

When transporting the spreaders for bulk materials, the supporting bars turn around vertical hinges 9 and set along the longitudinal axis of movement of the unit,
