Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The aim of the invention is to increase the operational reliability and reduce the energy intensity of the machine. On the frame 1 of the machine for the application of mineral fertilizers, a bunker 3 with a feed conveyor is installed. In the bunker 3 there is a discharge bar 6, having the form of a triangular pyramid, the bottom face 10 of which is inclined in the direction opposite to the direction of movement of the conveyor, and in cross section the bar has the form of an equilateral triangle. The fertilizer on the lateral face of the beam 6 slides to the feed conveyor. Gradually revealing the gap between the bottom edge 10 of the discharge bar 6 and the conveyor helps to reduce the load on the elements of the latter, reduce energy intensity and increase the operational reliability of the machine. 1 hp f-ly, 4 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for applying mineral fertilizers and other bulk materials.

The aim of the invention is to increase the operational reliability and reduce the energy intensity of the machine.

FIG. 1 shows a fertilizer application machine, general view: in FIG. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2

The fertilizer applicator includes a frame 1, to which the support wheels 2 are attached, a hopper 3 with a metering slot 4 and a feeding conveyor 5. A hopper 6 is installed in the hopper 3 6. Under the conveyor 5 there is a pump 7, under which centrifugal disks 8 are installed. The bar 6 is made in the form of a triangular pyramid consisting of side faces 9 and the bottom face 10. In the section (Fig. 3), the discharge bar has the configuration of an equilateral triangle. Bottom face 10 is installed with a lift in the direction of conveyor movement, i.e. in the direction of the metering slot 4.

The machine works as follows.

When moving across the field, the feed conveyor 5 enters the hopper 3 and passes with a minimum fence under the discharge bar 6. As it moves on the working section i, the rapsnorter 5 is gradually loaded with fertilizers and passes into the zone with an increased clearance under the lower edge of the 10 bar

6. Next, the fertilizers are transported to the metering slot 4, along the tube-guide 7 are fed to the rotating centrifugal disks 8 and distributed over the surface of the field. During operation, the fertilizer on the side edges 9 of the beam 6 slides to the feed conveyor 5. Gradually opening the gap between the bottom edge 10 of the discharge bar 6 and the conveyor 5 helps to reduce the load on the latter’s elements, reduce energy intensity and increase the operational reliability of the machine. Performing faces 9 and 10 of the same blanks improves the manufacturability of the machine in production.

Claims (2)

1. A mineral fertilizer application machine comprising a hopper with a feed conveyor, over which a discharge bar is installed with inclined side walls which taper in the direction of the conveyor’s working movement and fixed to the base with an additional bottom wall, characterized in that increase operational reliability and reduce the energy intensity of the machine, the bottom wall of the discharge bar is inclined in the direction opposite to the movement of the conveyor. 2. The machine according to claim 1, characterized in that, in order to improve processability manufacturing, the discharge bar has a cross-section formed by a plane perpendicular to the direction of conveyor movement, an equilateral triangle.
