SU1214004A1 - Mixer-spreader of mineral fertilizers - Google Patents

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to mixers of mineral fertilizer bodies.

The purpose of the invention is to improve the quality of mixing and the uniform distribution of fertilizers.

Figure 1 shows the mixer-spreader, rear view, in Figure 2 - the same, side view in FIG. 3 and 4 - mixing and spreading working body, rear view and cBepjcy.

About the fertilizer spreader of mineral fertilizers contains frame 1, bunker 2, divided by partition 3, feed conveyor 4, dispenser 5, receiving hopper 6, tukonapravlenie containing stepped conical divider 7 with protrusions 8 at its upper stage, cylindrical housing 9, centrifugal disk 10 with blades 11 and a hydraulic motor 12.

Mixer spreader works as follows.

Two types of non-mixing fertilizer or other materials for barking 12140042

They are fed into different compartments of the bunker 2, divided by a partition 3. The ratio of the parts can be changed by shifting the partition 3. Mineral fertilizers from the bunker 2

conveyor 4 through a common dispenser 5 is fed into a receiving funnel 6, from which they are fed to the upper part of the staggered splitter 7. At the same time, the top of the splitter 7 is installed in the center of the receiving funnel 6. Mineral fertilizers get to the top 7 and under the action of

15, the divider 7 and the projections 8 on its upper part are thrown against the walls of the casing and back. As mineral fertilizers arrive to a smooth lower degree of the divider 20 7, two

types of mineral fertilizers. The casing 9 along the entire length of the cylindrical surface is bent towards the stepped divider so that the mixed mineral fertilizers would enter the base of the smooth part of the divider 7, and then onto the disk 10 and the vanes 11. The rotation of the disk is carried out by a hydraulic motor 12.
