(54) ВЫСЕВАЮЩИЙ АППАРАТ(54) PLANTING DEVICE

1one

Изобретение относитс к области сельскохоз йственного машиностроени , в частности к высевающим аппаратам точного высева.The invention relates to the field of agricultural engineering, in particular to precision sowing apparatus.

Известны высевающие аппараты, включающие корпус с высевным окном, вертикально расположенный в нем высевающий диск с чейками по периферии 1.Known sowing devices, including a housing with a sowing window, vertically located in it, the sowing disk with cells along the periphery 1.

Недостатком данного аппарата вл етс то, что в зоне зар дки семенами высевающего диска происходит их механическое деформирование. Ограничена возможность увеличени числа чеек по периферии, что не позвол ет производить высев большого количества сем н при малых оборотах. Кроме того, этим аппаратом невозможно njpoизводить высев сем н с очень узкими междур дь ми (1-2 см).The disadvantage of this apparatus is that in the charge zone by the seeds of the sowing disc, they are mechanically deformed. The possibility of increasing the number of cells along the periphery is limited, which prevents the sowing of a large number of seeds at low speeds. In addition, this apparatus cannot produce seed with very narrow spacing (1-2 cm).

Цель изобретени - расширение технологических возможностей аппарата, повышение производительности и уменьшение повреждени сем н.The purpose of the invention is to expand the technological capabilities of the apparatus, increase productivity and reduce damage to seeds.

Поставленна цель достигаетс тем, что высевающий диск выполнен в виде двутаврового профил , причем чейки диска выполнены с двух сторон полки двутавра в видеThe goal is achieved by the fact that the sowing disk is made in the form of an I-beam profile, and the disk cells are made on two sides of the shelf of the I-beam in the form of

фигурных пазов, а на внутренней части корпуса в зоне расположени диска выполнен выступ, на котором перед высевающим окном выполнены насечки.shaped grooves, and on the inside of the housing in the area of the disk there is a protrusion on which notches are made in front of the sowing window.

Кроме того, в высевающем диске надAlso, in the seed disc above

5 чейками выполнены сквозные отверсти , а корпус аппарата в поперечном сечении имеет форму полукруга.5 cells are made through holes, and the body of the apparatus in the cross section has the shape of a semicircle.

Claims

10 is a section A-A in FIG. one; in fig. 3 - the inner part of the housing in front of the exit windows; in fig. 4 - arrangement of the shaped grooves on both sides of the flange of the I-beam, top view. The metering device includes a housing 1, having a semicircle shape in cross section with a protrusion 2 of its inner part to prevent seeds between the sowing disk 3 and the housing, a sowing window 4, in front of which notches 5 are made. I-side shelf for sowing a larger number of small seeds at a low speed of rotation of the sowing disc. This prevents injury to the seeds, and such a disc design allows the shaped grooves to be gripped and seeded sem n in a checkerboard pattern with a small distance between rows. In the sowing disc there are through holes 7 for spilling the seeds to its second side from the seed bunker 8 through the sem wire 9. The sowing machine works as follows. Seeds from the hopper 8 through this wire 9 enter the inside of the housing 1, the shape of a semicircle which allows you to adjust the gap between it and the sowing disk 3, at the same time part of the seeds through the through holes 7 is poured into the second half of the sowing disk 3 and also falls into the shaped grooves 6. The disk 3, rotating clockwise, on the ledge 2 transports in the grooves 6 one grain to the sowing window 4 and throws it into the soil alternately from one or the other side of the sowing disk. Seeds usually do not have a completely round shape and vary in diameter, even if they are calibrated. As a result, two grains can be positioned in grooves and so that they are not sown together, on the inside of the body, in the area of the disk 3, notches 5 are made, which give the grain a vibrational-rotational movement as it passes through this zone, resulting in a smaller the grain is dumped back into the inner part of the housing 1. The use of this sowing unit on the spans will allow precise sowing of small-seed crops, which have a rounded shape, which contributes to a better growth and development of plants and ultimately leads to an increase in yield. Claims. A sowing unit including a housing with a sowing window, a sowing disk with cells along its periphery vertically located in it, characterized in that, in order to expand technological capabilities, increase productivity and reduce damage to seeds, the sowing disk is designed as an I-beam profile, and the I-beams are made on both sides in the form of shaped grooves, and on the inside of the housing in the area of the disk there is a protrusion on which notches are made in front of the sowing window.

2. An apparatus according to claim 1, characterized in that through holes are made above the cells in the sowing disk.

3. The apparatus according to claim I, characterized in that the apparatus body in the cross section has the shape of a semicircle. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 435774, cl. A 01 C 7/04, 1971 (prototype).
