Изобретение относитс к се ьско1 хоз йству, в частности к машинам дл посева сем н.FIELD OF THE INVENTION The invention relates to seeding, in particular to machines for sowing seeds.

Известно устройство дл посева сем н, включающее сем проводы, привод и высевающий аппарат, состо5пций из плунжера,. Направл ющей втулки с установленным в ней подпружиненным клапаном tilНедостатком известного устройства вл етс низкое качество заделки сем н Б почву, так как при наличии остатков трав нистой растительности плунжер вдавливаетс в почву, а зерно не попадает в лунку.A device for sowing seeds, including sem wires, a drive and a sowing apparatus, consisting of a plunger, is known. A guide bushing with a spring-loaded til valve installed in it. A disadvantage of the known device is the poor quality of seed embedding of B soil, since in the presence of residues of grass vegetation the plunger is pressed into the soil and the grain does not fall into the well.

Цель изобретени - повышение качест.ва заделки сем н.The purpose of the invention is to improve the quality of seed seeding.

Поставленна цель достигаетс тем, что устройство дл посева сем н, включающее сем проводы, привод и высевающий аппарат, состо щий из плунжера, направл ющей втулки с установленным в ней подпружиненным клапаном, снабжено системой подачи сжатого воздуха , служащей дл образовани углублений в почвеThe goal is achieved by the fact that a device for sowing seeds, including these wires, an actuator and a sowing apparatus consisting of a plunger, a guide bush with a spring-loaded valve installed in it, is equipped with a compressed air supply system that serves to form cavities in the soil

в месте заделки сем н и состо щей из насадки, воздуховодов и крана, кинематически св занного с плунжером, при этом рабочий торец плунжера имеет скос, выполненный со стороны сем провода. Кроме того, незаглубл ема в почву втулка снабжена очистительным элементом.at the place of seeding of the seed and consisting of the nozzle, air ducts and crane, kinematically connected with the plunger, while the working end of the plunger has a bevel made from the side of this wire. In addition, the sleeve is not submerged in the soil and provided with a cleaning element.

Claims

15 valve. At the bottom of the sleeve there is a cleaning element 5, which serves until the plunger 1 is cleaned of adhering soil. A sem wire 6 is connected to the front of the sleeve, and a compressed air nozzle 7 is mounted at the back, which opens the jet to the place where the plunger 1 enters the ground. Valve 3 shows this 3, fed by a single-grain 3 sowing device through this wire 6. The drive consists of a double-arm lever 9 acting with one of its shoulders on the roller 10 fixed to the upper end of the plunger 1. On the plunger 1 a fixed washer 11 is rigidly fixed which rests on the spring 12. The washer 11 of one-sided action hooks on the lever of the air valve 13 as it moves downwards, during the return stroke it slips. Limits the lift of the plunger 1 bracket 14, in which the washer 11 rests in the upper position, the bracket 14 is rigidly connected to the sleeve 2. To adjust the stroke of the plunger, a screw mechanism 15 serves. , receiving the drive from the wheel drive 18. The device is adjusted in height by a screw mechanism 19, which moves the housing 20 relative to the wheel 18, on which all other parts are mounted. To prevent the seed from gathering from the plunger 1 when embedded in the ground, the plunger is formed with a chamfer 21. In sowing machines Seals are installed instead soshUstroystvo device operates as follows. When moving across the field, the wheel 18 drives the Cams 16c with rollers 17, moving the lever 9, which during upward movement with a long arm acts on a single grain sowing apparatus of periodic action (not shown) and drives down the plunger, plunger 1 with a washer 11 opens valve 13. An opening jet of compressed air is supplied, which forms a depression in the soil, spreading out plant residues and dry layers of soil. As soon as the jaw 11 penetrates the lever of the crane 13, the crane under the action of the spring 54 is not shown) kryvaets, stopping the supply of compressed air. Plunger 1, continuing its downward movement, runs over valve 3, squeezes it into slot 4, releasing this 8. Thanks to the plunger 1 speeding up, the latter catches the free-flow Sem 8 and introduces it to a certain depth into the soil in the previously formed well. After that, the plunger 1 is returned to its upper position by the action of the spring 12. In this case, a spring-loaded valve 3 is released, which takes its initial position and blocks the path to the grain, which by this time comes from the single-grain sowing apparatus through this wire 6. Then the cycle repeats. The application of the proposed device will improve the quality of sowing of seeds, which, in turn, creates a prerequisite for dp yield increase. Claim 1. Sowing device, including sem wires, drive and sowing device, consisting of a plunger, guiding the sleeves with a spring-loaded valve installed in it, in order to improve the quality of seed placement, the device is equipped with a system supply of compressed air, which serves as a dp for the formation of recesses in the soil at the place of seeding and consisting of a nozzle, air ducts and a crane, kinematically connected with the plunger, while the working end of the plunger has a bevel made from the side of the wire .

2. Device by. Claim 1, characterized in that the sleeve which is not buried in the soil is provided with a cleaning element. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 104865, cl. A 01 C 7/18, 03/28/56 (prototype).,
