UA19412U - Fertilizer distributor - Google Patents

Abstract

A fertilizer distributor contains a fertilizer tank, a shaft, a dispenser as screws with a right screw and a left one, bodies with dosing openings, closed by the lids of funnels. On the shaft at the end of the screws above the funnels disks are fixed, the diameter of those is larger than the outer diameter of the screws.

Description

Description of the invention

The useful model refers to agricultural engineering and, in particular, to seed drill assemblies 2 intended for sowing mineral fertilizers (fats) in the furrow.

The closest in design is the fat seeding device |1), which consists of a body, a hopper for fat, a shaft on which the multi-sided turns of the screws are fixed, funnels, which are fixed at the exit from the body of the shaft with screws. Such a device doses loose material well, but sowing in the furrow is pulsating, due to the presence of auger turns, which significantly worsens the quality of fat distribution in the furrow, especially when sowing small rates. 70 The problem to be solved by this invention is to significantly improve the quality of fat distribution in the furrow by ensuring the equalization of the pulsating flow of fat after the screws, creating a uniform flow of fat into the furrow.

The task is proposed to be solved by creating an adaptation to the auger fat seeding device, in which discs are fixed on the shaft above the funnels in the end of the augers, the diameter of which is greater than the outer diameter of the augers, and the lower parts of these discs are covered by fixed bottoms. The quality of the work of this fat-seeding device is that, in order to equalize the pulsating flow after the augers, an accumulation chamber is created between the discs, bodies and bottoms, in which the discs are its movable walls.

The content of the useful model is explained by the drawings, where the general structure of the fat-seeding apparatus is shown in Fig. 1, in Fig. 2 the view along the arrow A in Fig. 1, in Fig. 3 the cross-section B-B in Fig. 1, in Fig. 4 the cross-section B- B in Fig.3.

The fat sowing device consists of a fat hopper 1, a shaft 2, a dispenser in the form of screws with right Z and left 4 screws, discs 5, housings b with dosing holes, funnels 7 closed with lids. In the lower part of the dosing window 8, on its edge, made a narrow slot 9, the width "v" of which is greater than the maximum size of the fat particles that are sown, and the lower part of the discs is covered by the bottoms 10.

The fat seeding device works as follows. During the rotation of the shaft 2 with screws З and 4, the fats from the middle of the hopper 1 are moved by turns of screws З and 4 to the dosing windows 8, where they are dumped into the storage chambers, which are created by disks 5 and cases 6 with bottoms 10, and for more uniform filling with fats storage chambers, some of them are fed through Slot 9.

The fat from the storage chambers is uniformly discharged into the furrow by the rotating discs 5 due to frictional (frictional) forces on their surface. high school

Claims (3)

The formula of the invention "-- 1. A fat seeding device, which contains a hopper for fat, a shaft, a dispenser in the form of screws with right and left screws, housings with dosing holes, closed funnel covers, which is distinguished by the fact that on the shaft end of the screws above the funnels, discs are fixed, the diameter of which larger than the outer diameter of the screws. - 2. A fat seeding device according to claim 1, which differs in that the lower part of the discs is covered by the bottoms of the housings. with 3. The fat seeding device according to claim 1, which differs in that in the lower part of the dosing holes on their edges "" narrow slits are made, the width of which is greater than the maximum size of the particles that are sown.
