Abstract

The invention relates to the field of agricultural engineering, in particular, to the seed directors of sowing machines. The aim of the invention is to improve the uniformity of the distribution of seeds along the row. A seed guide made of an elastic material in the form of a semi-tangent curve is installed in a metal rectangular brook with a coulter hopper splitter, on its back wall. The direction of the seed from the rear wall of the wire to the front is carried out with a smooth transition of the trajectory of movement and reduction of the rebound of the seeds, which eliminates their dispersion after the seeds leave the transport device. 1 hp f-ly, 2 ill.

The invention relates to the field of agricultural engineering, in particular, to the seed directors of sowing machines.

The aim of the invention is to increase the uniformity of seed distribution along the row.

Figure 1 shows a vomer with a semi-captive seed guide, oid at the side; figure 2 - section aa in figure 1.

The semi-tangoid guide of the seed of the coulter contains a metal rectangular stream, a hollow rack - this wire 1 with a suller, a tip of 2 coulters (not shown). On the rear wall of this 3 wire 1, a guide 4 of seeds made of elastic material is installed in the form of a semi-tangent curve.

The semi-tangial guide of the family member works as follows.

When the seedlings move along the sown area, the maral 2 of the opener funnel forms in the soil, and at the same time, from the same funnel, the seed 1 is fed into the metal rectangular stream, the rack — this wire. At the same time, those seeds that move near and along the back wall of the 3 semester wire 1, meet with the breast made of elastic material of the seed heads.

semi-tangular curve 4, continue to move further to the soil surface along the latter. Moreover, due to the fact that such a semi-tangential curve is very slow, i.e. smoothly and endlessly, tends to a vertical asymptote, the role of which is played by the back wall of the 3 semes of the I wire, and then the transition from a rectangular path

The movement along the back wall of 3 sems of wire 1 on a semi-tangent curve will be smooth. In addition, taking into account the fact that the seed guide is made of elastic material, the rebounding of a part of the seeds from it will be eliminated due to the quenching of the seed seed puller on the soft surface of the guide. Further, those seeds that move along a semi-tangenoidal curve guide are sent to the front of the rectangular stream, closer to the back of the tip 2, and thus the seed seed flow is compacted to some extent. The direction of the seed from the back wall 3 of this wire 1 to the front of the latter with a smooth transition of the path of movement and a reduction in the rebound of seeds makes it possible to eliminate their dispersion after the seeds leave the transport device near the rear wall 3 of this wire 1, elimination of gaps between seeds in i

close to sparse flow without a guide. Consequently, the totality of the above factors together makes it possible to increase the uniformity of distribution of seeds over the length of a row.

The use of this invention increases the uniformity of seed distribution over the length of the row and thereby eliminates the thinness and neglect of the crops in the planted soil row, which has a positive effect on the increase in field germination of seed and crop yields.

Claims (2)

1. A collar containing a hollow resistant, sem wire with a pair and a curved seed guide located on the rear wall of the sem wire, characterized in that, in order to increase the uniformity of the seed distribution along the length row, the seed guide is made in the form of a semi-tangent curve. 2. The collet of claim 1, wherein that the seed guide is made of elastic material. 3
