SU94935A1 - Granulated Fertilizer Making Machine - Google Patents

Description

The invention is based on machines for the preparation of granulated fertilizer consisting of a hopper, a press drum with a ribbed screw fixed on a vertical rotator, the shaft, a net low-speed disk, and a sheath mounted under the mesh disk.

In comparison with the known machines for the same and similarly designed constructions, the described machine has a higher productivity and provides increased density and roundness of g-ranul.

The design feature of the proposed machine is that the ribbed auger is equipped with blades at the top, a cone with pressuyush, blades and knives with it at the bottom, and to give OKpymoii pellets in the machine the shape of the crushing screen.

The drawing shows a diagram of the machine in three projections.

On the wheel frame 7, a press drum 2, a grinding screen 3 and a drive mechanism are mounted.

The frame 1 is a diagonal strut and a longitudinal frame with 1 welders for attaching the rear running wheels 4 and a front end with the wheels 5.

The pressing drum 2, rigidly fixed on the frame, is made in the form of a cylinder 6, in the BepxHeii part of which the bunker 7 is fixed, in the lower part there is a fixed mesh disk 6 placed in the holder 9.

In cylinder 6, there is a vrashayup1i1 in subpipe1) and IT vertical shaft / 2, near which three pairs of HBCTeii 1-3 are rigidly mounted. a ribbed screw J4 and a cone 15 for applying mass to the screen disk 8.

The cone 15 is provided with a extrude (with the help of their legs 76 and knives 77; the vanes and knives fit snugly against the inner surface of the disk.

No. 94935-2 -

In the lower part of the press drum, the knives 18 are mounted some distance from the outer surface 8.

Rolling of the face is carried out on the curved surface of the transverse strips 19 in the swinging movement of the screen 3 suspended on four elastic bars 20.

The drive mechanism serves to drive the shaft 12, the drum 2, the screen 5 and 18, and consists of the driving pulley 21 fixed on the shaft 22, from which the shaft 12 is driven through the spur gear 23 and 24, the shaft 25 and gear 26 and 27.

On the shaft 22, a sprocket 25 is fastened, resulting in rotation through a roller chain sprocket 23 rigidly mounted on the shaft 3), at the opposite end of which there is a gear 3 / driving the iozhi 18.

The sprocket 32, fixed on the shaft 30, causes the sprocket 53 and the crankshaft 34 to rotate through the roller chain. The knee of the shaft 34 is connected to the connecting rod 55 attached to the bottom of the screen 3 with its end.

Poured into the hopper 7, the mass (fertilizer and humus) goes to the blades m 13, which pre-mix the fertilizer with the humus. As it goes down, the mixed mass is captured by the rotating screw 14 and is fed under pressure to the cone 15 and pressing blades 16, which force the mass through the holes of the mesh disk 8. To clean the clogged plant residues (straw, hay, etc.) of the holes S, knives 17.

The mass under the pressure through the holes of the disk 8 in the form of dense columns is cut by knives 18. The cut columns fall on the screen 3, roll in and then in the form of granules enter the collection boxes.
