Изобретение относитс к сельскохоз йственному машиностроению, в частности к се лкам, которые могут быть использованы дл высева сем н различных -сельскохоз йственных культур и удобрений.The invention relates to agricultural machinery, in particular, to crops that can be used for sowing seeds of various agricultural crops and fertilizers.

Известны се лки, содержащие установ- 5 ленную на опорных колесах раму с бункером , в котором размещен высевающий ап . парат в виде вращающегос цилиндрического пустотелого барабана со сквозными, чейками дл сем н, установленного на не- Q подвижной трубчатой оси с двум полост ми, посредством одной из которых чейки в зоне захвата сем н сообщены с источником вакуума , а посредством другой в зоне вь1броса сем н - с источником избыточного давлени воздуха, и сем - и тукопроводы, соот- 15 ветственно сообщенные с рабочими органами дл заделки в рочву сем н и удобрений 1..Seeds are known that contain a frame with a bunker installed on the support wheels, in which the seed meter is placed. Parameter in the form of a rotating cylindrical hollow drum with through cells for seeds mounted on a non-Q movable tubular axis with two cavities, through one of which the cells in the seed pickup zone are connected to a vacuum source n - with a source of overpressure of air, and sem- and tubing lines, respectively, communicated with working bodies for embedding into seed and fertilizer 1 ..

Недостаток указанных се лок - зна 1ительна сложность конструкции, обуслов- ° ленна тем, что дл высева сем н и удобрений необходимо иметь два самосто тельных высевающих, аппарата с автономными механизмами их привода.The disadvantage of these springs is the complexity of the design, due to the fact that for sowing seeds and fertilizers, it is necessary to have two independent sowing machines, devices with autonomous mechanisms of their drive.

Цель изобретени - обеспечение высева сем н и удобрений одним высевающим аппаратом и упрощение конструкции се лки.The purpose of the invention is to ensure the sowing of seeds and fertilizers with one sowing apparatus and to simplify the construction of the crop.

Поставленна цель достигаетс тем, что бункер разделен продольной перегородкой на два отсека дл сем н и удобрений, а на барабане в промежутках между чейками дл сем н установлены- гофрированные упругие кольца, причем последние в отсеке бункера дл сем н и чейки в отсеке бункера дл удобрений перекрыты кожухами.The goal is achieved by the fact that the bunker is divided by a longitudinal partition into two compartments for seeds and fertilizers, and on the drum in the intervals between the cells for seeds there are corrugated elastic rings, the latter in the compartment of the bunker for seeds and the cells in the bin for fertilizers covered with covers.

Кроме того, гофрированные кольца, установленные на барабане, выполнены из резины.In addition, the corrugated rings mounted on the drum are made of rubber.

На фиг. 1 изображена се лка, вид сбоку; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 2; на фиг. 4- разрез В-В на фиг. 2.FIG. 1 is a side view of the blue; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 is a section on BB in FIG. 2

Се лка содержит установленную на опорных колесах 1 раму 2 с механизмом 3 навески ее йа трактор, бункер 4, разделенный продольной перегородкой 5 на два отсека - отсек 6 дл сем н и отсек 7 дл минеральных удобрений.The crop contains 1 frame 2 mounted on support wheels with a mechanism 3 hinged on its tractor, a bunker 4 divided by a longitudinal partition 5 into two compartments - compartment 6 for seeds and compartment 7 for mineral fertilizers.

Claims

In the lower part of the bunker 4 there is placed a sowing machine in the form of a rotating cylindrical hollow drum 8 mounted by bearings 9 on a fixed tubular axis 10 rigidly fixed on racks 11. On the cylindrical part of the drum there are through-holes 12 for seeds, which are in the pick-up zone communicated by confusors 13, cavity 14, axis 10 and a bunker cyclone 15 with a vacuum source (not shown), and in the zone of seed ejection, cavity 16 of axis 10 is connected with a source of excess air distribution (not shown). . In the gap between the cells 12, on the outer part of the barbata-1, elastic corrugated rings 17 are rigidly fixed, made, for example, of rubber. The cells 12 in the compartment 7 of the fertilizer hopper and the corrugated rings 17 in the compartment 6 for the seeds, respectively, are covered with covers 18 and 19. In the lower part of the drum, over the cells 12 and the corrugated rings 17, there are cone-shaped receivers 20 for the seeds and 21 for the fertilizers, which by means of these wires 22 and tubing 23, communicated with working bodies for embedding seeds and fertilizer in the soil, made in the form of cultivator paws 24. Sem wires 22 and cultivator 23 feed lines 23 are installed so that a number of mineral fertilizers second, embedded in the ground, was positioned a little deeper, but strictly under the adjacent seeded seeds. Selka works as follows. As the spindle moves from the rotation of the wheel 1 through the drive mechanism, the drum 8 rotates in the direction indicated by the arrow. By creating air discharges in the last 12 cells, the passage through the compartment 6 of the bunker seizes the seeds. If the seeds are stupid, underdeveloped, fragmented, their geometrical dimensions will be less conservative, and they freely pass through the cells 12, confuser 13, cavity 14 and settle in the bunker-cyclone 15. Other inclusions and seeds are removed from the seed. weed plants whose geometrical dimensions are smaller than the dimensions of the holes of the cells 12. The cells filled with conditioned seeds pass under the partition 5 of the drum 8 and leave the zone of action of the vacuum. As the drum rotates further, the seeds held by the casing 18 move to the receiver 20. If the seed does not fall into the receiver 20 arbitrarily, when the cell 12 is aligned with the diffuser 13, the seeds are pushed out of them by high pressure air into the seed receivers. wires 22, and through it through the hole in the cultivator paw 24- into the soil. At the same time, when drum 5 is corrupted, corrugated rings 17, pass through pockets formed by casings 19, recess the mineral fertilizers and transport them to receiver 21. Fertilizers from receiver 21 gravitate by way of the pipeline 23 and enter through the hole in cultivator paw 24 into the soil. Thus, the sowing of seeds, their rejection, the application of mineral fertilizers, pre-sowing tillage is carried out simultaneously, and the sowing of seeds and fertilizers is carried out by one sowing apparatus, which allows to significantly simplify the design of the seeds and increase the yield of grain crops due to the selection of conditioned seeds. and simultaneous fertilization with sowing. Claim 1. Seed comprising a frame with a hopper mounted on the support wheels in which the sowing unit is placed as a rotating cylindrical hollow drum with through cells for seeds mounted on a fixed tubular axis with two cavities, through one of which the seizure capture zone is in communication with a vacuum source, and through the other in the seed ejection zone it communicates with a source of air overpressure, and the seed also interconnects with the working bodies with embedment of seeds and fertilizers into the soil, characterized in that, in order to ensure the sowing of seeds and fertilizers with one sowing apparatus and simplify the design, the bunker is divided by a longitudinal partition into two compartments for seeds and fertilizers, and on the drum between cell d Corrugated rings are installed, the latter in the compartment of the seed bin and the cell in the fertilizer compartment of the fertilizer are covered with covers.

2. Section 1 under item 1, characterized in that the corrugated rings are made of rubber. Sources of information taken into account in the examination 1. Patent GDR № 120110, cl. A 01 C 7/04, 1976 (prototype).
