Description

SOWING UNIT FOR DRILLED SEEDS

The utility model relates to agricultural engineering, in particular to apparatus for the precise sowing of seeds of cultivated crops.

There is a known sowing machine SST-12A seeder, adopted for the nrototype, consisting of a housing, a seed hopper, a reflecting roller, a mesh disc with kyptsyh grooves and wedge ejectors 1. This device is used for the exact sowing of sugar beet seeds.

The disadvantage is this; The apparatus is the dispersion of the flight paths of seeds after they are ejected from the cellular disk using wedge ejectors. The variety (| of the properties of the seeds and the position of their center of gravity in the cells is the spread of the trajectories of the rebound from the ejector, especially the drained seeds, as a result of which the accuracy of their layout in the sowing furrow is impaired.

Utility model; solves the problem of increasing the accuracy of seed distribution in the furrow. 3i © is achieved by the fact that for a sowing apparatus containing a housing, a seed scrubber, reflecting roller, a cellular disk with an annular groove and a wedge ejector, the cells are conical, and the wedge ejector is located outside the path of free exit of seeds.

The utility model ensures the free exit of seeds from the cells without the action of an ejector with constant flight paths tangential to the circumference of the disk at the point of their ejection.

Figure 1 presents a useful model of the sowing apparatus in lvuh projections.

MKI A 01 from 7/04

an annular groove 6 and a wedge ejector 7. The cells have a conical shape, and the ejector is installed above the path of free exit of seeds.

During the operation of the apparatus, coated seeds fill individually 5 cells of the growing; sowing seeds; its disk 4. The reflecting roller 3 moves away the extra seeds from the danger zone of crushing and crushing when the cells enter the annular body of the device. In the first part of the apparatus, housing 1 ends, forming an exit window for seeds, through which they fly out in the direction of vector V. The conical shape of the cells eliminates the possibility of jamming of the seeds when leaving them, as is the case with the prototype with cylindrical cells. Free flow of seeds is facilitated by weight and centrifugal forces, which are higher in dragee, heavier seeds. These forces replace the action of the ejector. The direction of the ejection velocity vector V is more stable than after reflection from the ejector, in addition, it is opposite to the direction of movement of the seeder, as a result of which the absolute speed of the seeds decreases more significantly than when working with the ejector, and this reduces the likelihood of rebound and rolling of seeds in the sowing furrow, i.e. st) improves the quality of distribution. The wedge ejector 7 in the utility model has a supporting role. It cleans; cells from adhering weeds in the form of dust, adhering fragments of the seed coat, and possibly stuck seeds, the number of which, according to our experiments, reaches 2%. These seeds are reflected from the ejector in the direction of the vector W and fall into the seed furrow. Their placement in the furrow is random with respect to normally sowed seeds, but because of the small number of seeds, they practically do not affect the quality of piece placement of seed in the furrow.

Thus, the utility model of the BbiceBaraiHeix) apparatus improves the quality of the distribution of pelleted seeds along the furrow without noticeable complication of its design.
