Abstract

The invention relates to agricultural machinery. The purpose of the invention is to reduce energy intensity and increase reliability. The organic fertilizer applicator includes a body mounted on the chassis with a feed conveyor and a spreading tool in the form of drums. The grinding drum of the working body is equipped with blades 7 and knives 6. Knives 6 are evenly placed along the length of the drum and are installed perpendicular to its axis. On each knife on both sides at an angle to it are fixed the blades 7, while the adjacent blades are installed between the blades with overlap. The cutting edge of the knife 6 of the chopping drum is set tangentially to its outer surface. The working sides 8 of the blades 7 are sawtooth, the number of blades 7 between the blades 6 decreases from the middle of the drum 5 to its ends, each blade 7 of the drum 5 is inclined in the direction opposite to the direction of its rotation by an angle of 10-30 ° from the axis. 4 hp f-ly, 6 ill.

The invention relates to agricultural machinery, in particular to machines for applying organic fertilizers.

The purpose of the invention is to reduce the power to drive the spreading of their working bodies and to improve the quality of grinding fertilizer.

FIG. Figure 1 shows schematically the proposed fertilizer applicator, a general view of the machine; in fig. 2 - grinding drum, general view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 and 6 - drum reamer, variants of blade spacing between knives.

The LA fertilizer for applying organic fertilizers contains a body 2 mounted on chassis 1 with a feed conveyor 3 and a spreading working body consisting of a spreading drum 4 and a chopping drum 5. On the chopping drum 5 evenly along its length are placed knives 6 that are installed perpendicular to the axis the drum 5. The cutting knife of the knife 6 is placed tangentially to the outer surface of the drum 5. On each knife 6 from the circumference, the blades 7 are symmetrically fixed to it. The working side 8 of the blades 7 is sawn oh form. The blades 7 are located on the surface of the drum 5 along a helical line, and the direction of the screw lines of the adjacent blades is opposite to each other. The blades 7 are inclined in the direction opposite to the direction of rotation of the chopping drum 5 at an angle of 10-30 ° from the axis. The number of blades 7 between the blades 6 decreases from the middle of the drum 5 to its ends. The knives 6 have cutting edges 9 and 10.

Maplena for organic fertilizer works as follows.

When the feed conveyor 3 is turned on, the fertilizers from the body 2 are conveyed by the conveyor 3 to the turning grinding machine 5, the knives 6 of which cut the fertilizer layer along the ujHpHHe body into separate parts with edges 9 and 10, breaking its solidity. In each separate part of the fertilizer layer, the blades 7 with their working edges 9 grind the fertilizers and direct them to the spreading drum 4, which distributes the fertilizers over the field. The use of the invention allows to reduce the power cost of the drive spreading device, provides high-quality grinding of fertilizers, which increases the uniformity of distribution of fertilizers in the field.
