SU386600A1 - CENTRIFUGAL FERTILIZER SPREADER - Google Patents

Description

one

The invention relates to the field of agricultural engineering, in particular, to machines for fertilizing.

The known centrifugal fertilizer spreaders, including a bunker, a scattering drum with a horizontal axis of rotation, and a metering unit with a feeder for feeding ULT, placed inside the drum, do not provide the required equilibrium distribution of fertilizers over the surface of the surface while increasing the degree of spreading.

In the proposed centrifugal spreader, it forms; the surface of the drum is provided with exit windows, overlapped with: MI leveling interlocks.

The drawing shows a schematic diagram of the proposed pentrobug spreader with a section along A-A.

The centrifugal spreader consists of a bunker / with a pivoting device 2, a metering body 3 with a g) 4 and a scattering drum 5, fixed on the drive shaft 6 and rotating around a horizontal UN. The forming surface 7 of the drum is provided with exit windows -and a, which may overlap the adjusting flaps 8.

The principle of operation of the present invention is as follows.

Fertilizer from the hopper / through the metering device into the feeder 4, which; delivers them to the inside of the drum 5. When the fertilizer is being driven by the centrifugal force, they fly out into the output windows a, not blocked by the shutters 8. The position of the shutters can be used to direct the flow evenly to both sides of the vertical axis of the drum 5. At the same time, the fertilizers Nodachn places before leaving the windows are not exposed to the drum. By appropriate installation of the shutters 8 and the supply point, it is possible to communicate the flow of fertilizers. The right direction and ensure their uniform distribution over the floor surface with increasing spreading width.

Subject invention

A centrifugal fertilizer spreader, including a spreading drum rotating around a horizontal axis, an feeder for feeding fertilizers inside the drum and a drive mechanism, characterized in that, in order to evenly distribute the fertilizers as the spread width increases, output windows are made in the drum surface, overlaid with LID dampers.
