Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for seeding mineral fertilizers. The purpose of the invention is to improve the uniformity of seeding and reliability of work. The device contains a hopper 1, a casing with a screw 2 installed in it, at the end of which the impeller 10 is installed at an angle, under which are seeded windows 8 with sieves 9 and spreading discs 14. A casing rate regulator in the form of a damper with an edge parallel to the axis of the screw, and bevels to its ends. Fertilizers coming from the bunker 1 by the screw 2 through the edges of the gate of the regulator of the seeding rate are evenly sown on the soil surface and, in addition, are fed to the sowing windows 8 with sieves 9. The blades of the impellers 10 crush the fertilizers, push them through the grill 9, which, entering the discs 14 are spread evenly over the soil surface. 4 il. 0 (L

The invention relates to agricultural machinery industry, in particular to seeding devices for mineral fertilizers, which can be used for the continuous surface application of solid mineral fertilizers and other bulk materials.

The purpose of the invention is to increase the uniformity of seeding and reliability of work.

Fig. 1 shows a device for planting mineral fertilizers, rear view; FIG. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB in FIG. I; Fig, 4 - impeller, {side view,

I The device contains a bunker 1, a screw | 2 with left and right winding with a drive sprocket 3, under which casing A is placed, on the casing 4 with clips 5 there is fixed a regulator 6 of the norm of crop fertilizer in the form of a damper, the upper edge of which in the unloading zone 1SI fertilizer from the hopper is parallel to the bc rotation of the screw 2 and is located in it, and has edges of variable size on the edges. The guides 7 have: sowing windows 8, equipped with sieve- | {4И 9, above sieves 9 are installed under the ANGLE to the axis of rotation of the screw 2 wing 10 with blades 11, the angle of inclination is chosen in such a way, h at about Vera 1 | 2 1enii auger impeller 10 soprika- fayuts sieves with 9 throughout their length |) Static preparation surfaces. For uninterrupted fertilizer delivery to the jfepM 12, the impellers 10 at the gathering point of the bender with the turns of the screw 2 are equipped with buttons 13, and under the guides 7 are fixed. spreading discs 14, driven by conical pairs 15,

The device works as follows.

From the bunker I, the fertilizers are fed to the casing 4 and the screw 2 are fed to the seed windows 8, the impellers 10 rigidly mounted on the screw 2, in contact with the working surfaces of the meter 9, feed the fertilizers and the chambers 12 and crush the formed fertilizer lumps along the entire surface of the sieves 9, unrestricted, fertilizers are delivered to the grinding zone through the windows 13 of the wing tOK 10 at the place where they leave the turns of the Ka 2 tire.

fertilizers are fed to centrifugal spreading discs 14 and spread around the floor surface. At the same time, the turns of the auger 2 fertilizer through the upper edge of the editor 6 of the seeding rate are scattered over the floor surface. In the zone of unloading fertilizer from the bunker I, the upper edge of the regulator 6 of the seeding rate 6 is parallel to the axis of rotation of the auger 2 and is located above it (to avoid seeding fertilizer idle device), and along the edges has symmetrical sections, ensuring uniform seeding along the entire length of the screw 2. The seeding rate of fertilizers is adjusted by moving and fixing the regulator & seeding rate on the outer surface of the casing 4,

The device is driven as follows.

The screw 2 is driven by an asterisk 3 fixed on it, then through conical pairs 15 steeply, the 1st moment is transferred from the screw 2 to the centrifugal disks 14. Depending on the composition of the fertilizers, the seeding can be carried out by the spreading centrifugal disks 14 and the screw 2 independently,

The presence of the valve 6, which has a rim parallel to the axis of the screw and bevels, as well as the installation of inclined impellers 10 at the ends of the screw, ensure uniform sowing and reliable operation of the device.
