Description

one

The known machines for applying bulk fertilizers iB between suitable shrubs do not ensure fertilization in the bite zone, i.e., in the zone of location of the largest number of roots.

In the proposed machine, in contrast to those known in the material pipeline, at a distance from the lower part of the opener, the increasing depth of fertilization, a device was installed to retract part of the fertilizer, made in the form of a plastip inclined towards the bite zone, above which is placed a finger-shaped disk driven into Fragments from the interaction of the fingers with the soil, dumping, vayush, fertilizer from the plate and sealing them.

To provide the required ratio of fertilizer application to the prepared layer and to the zone close to the bite, the plate is fixed with the possibility of not interfering about the axis of the material pipeline.

FIG. 1 shows the proposed machine, side view; in fig. 2 - a device for removal of fertilizer, vnd rear; in fig. 3 - the same plan.

Bulk fertilizer application machine consists of a bunker / with fertilizer feeder, 2, frame 3, copying wheels 4, support wheel 5, mechanism 6 for moving the machine to the transport position, drive 7

working bodies, coulters 8, locking 9 and device 10 for removal of fertilizer.

The device for removing part of the fertilizer (Fig. 2 and 3) consists of a plate // pivotally mounted on a horizontal axis 12, which is fixed to the bracket 13 with the possibility of moving in the grooves 14. At one end of the plate 1J there is a stop J5 and an axis 16, on which the bracket 17 is mounted with an axis 18 and a spring 19. An axial disk 20 is located on the axis 18. At the other end of the plate 11 there is a spring 21, which ensures the adhesion of the finger-shaped disk 20 to the ground.

When the machine is moving, the fertilizers from the hopper / by means of mechanism 2 are fed into the pipelines of the openers 8, where they are divided into two streams. One part of the fertilizer is directed to the furrows formed by the coulters 8, and the other to the device 10 to divert part of the fertilizer. The toe disc 20, rotating from the interaction with the soil, drops the fertilizer from the // plate into the zone close to the bite, and embeds it in the surface layer of the soil.

Sealing of fertilizers introduced into the furrows and leveling the soil after the passage of the coulters produces 5; by the stalls 9.

When a finger-like disk 20 encounters an obstacle, such as a plant stump,
