Description

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

The purpose of the invention is to improve the uniformity of fertilizer application by providing the cavity for each tooth to pick up and move equal in volume doses of material.

FIG. 1 shows a machine for applying organic fertilizers, general view; in fig. 2 is a distributing device, a plan view; in fig. 3 shows section A-A in FIG. 2

The fertilizer machine contains a body 1, at the bottom of which a feed conveyor 2 and a chopping feed drum 3 are located. In the front part of the body 1 there is a rotary spreading device consisting of a casing 4 on which the manure flow dividers 5 are firmly fixed. Inside the casing 4 there is a rotor 6 with radially fixed sawtooth blades 7. Between the teeth of the blade 7, slots 8 are made, and they are designed in such a way that free passage of the sawtooth blades 7 through flow dividers 5. The casing 4 has a discharge window 9.

Flow dividers 5 are made in the form of concentrically located arcs located on radii defined by the ratio

, i; where RI is the radius of the first arc from the center of the rotor;

H „is the radius of the pth arc from the center of the rotor. The organic fertilizer application works as follows.

The fertilizers loaded into the body 1 are moved by the conveyor 2 to the chopping-feeding drum 3, during rotation of which not only partial grinding of the mass takes place, but also feed to the rotor 6. The flow dividers 5 installed in the casing 4 provide additional grinding and even separation of the fed mass from the center rotor 6 to its periphery. The mass divided into equal volumes is captured by the saw-tooth blades 7 and brought to the discharge window 9. Thus, a uniform loading of fertilizers is ensured by a uniformly non-saw-blade blade 7.

Such a rotor 6 design provides different particle escape rates, thus, when particles come off the sawtooth blade 7, they have different initial 5 flight conditions, namely different initial radii of departure, which predetermines the qualitative distribution of fertilizers across the pickup width.

MACHINE FOR APPLICATION OF ORGANIC FERTILIZERS, including a body, a feed conveyor, at the output of which a distributing device is installed, made in the form of a rotor with radially arranged and sawtooth-shaped blades, characterized in that, in order to increase the uniformity of fertilizer application by ensuring capture and movement of each with a tooth of a blade of equal doses of material in volume, the rotor is equipped with flow dividers rigidly fixed on its casing, made in the form of concentrically arranged arcs, while between the teeth of each blade have slots for passing through them arcs of flow dividers, the latter being located at radii determined by the ratio where Ri is the radius of the first arc from the center of the rotor; R „is the radius of the nth arc from the center of the rotor.
