Description

one

The invention relates to agricultural engineering, in particular to the precision seed drill seed crops, and can be used in seed farms.

Known planters containing pivotally mounted on the frame by means of radial leads openers with installed and them sowing devices and bunkers, which are communicated by nozzles with the main bunker, equipped with a shaft with a tedder for seeds [1].

The disadvantage of these drills is the complexity of the design, which consists in the availability of a source of compressed air, necessary for transporting seeds from the main bunker through the nozzles into the openers bunkers.

In addition, the pneumatic conveying of seeds from the main hopper to the coulters' hoppers does not ensure uniform

Node loading the last seeds and maintaining a given level in them.

The purpose of the invention is to simplify the design of the planter and increase the uniformity of loading seeds seed hoppers openers.

The goal is achieved by the fact that each nozzle is made of rigid material and pivotally connected to the main bunker and opener bunker, and inside the nozzle there is a rod with radial blades that is pivotally connected by means of a crank to the tedder shaft.

The drawing schematically shows the proposed planter.

The seeder contains a frame 1, on which the main bunker 2 is rigidly fixed, in which the shaft of the agitator 3 with the crank 4 is pivotally mounted. A bracket 5 is attached to the lower part of the main bunker 2, which is connected pivotally with the bracket 6 of the loading nozzle 7. Outlet hole 3 91

The main hopper 2 and the loading nozzle 7 are connected to each other by means of a rubber cuff 8. The other end of the loading nozzle 7 through the bracket 9 is pivotally connected to the bracket 10 of the hopper 11 of the metering device 12, which is mounted on the opener 13.

The hinges for mounting the pipe 7 to the bracket 5 of the hopper 2 and the bracket 10 of the opener 13 are placed so that, together with the radial leash 14, they form a psrallelogram suspension mechanism of the opener.

The cavities of the loading nozzle 7 and the opener bunker 11 are connected by means of a rubber cuff 15. The opener 13 is pivotally connected to the frame 1 via a radial leash 14 and a stand 16.

In the cavity of the loading pipe 7 is placed a rod 17 with radial blades 18, which is pivotally connected with the crank 4.

The seeder works as follows

The seeds fall asleep in the main bunker 2. Under the action of gravity, the seeds move along the loading nozzle 7 into the bunker 1, the vomer 13. At the drive, the seeder is transferred to the working position by lowering the frame 1.

When the seed drill moves, the sowing machine 12 of the coulter 13 sows seeds, while the field surface is copied by the coulter 13 using a parallelogram suspension, the functions of which are performed by the radial leash 14 and the loading nozzle 7. During the operation of the sowing machine 12, a part of the seed from the bunker 11 of the opener is sown However, immediately the place of the sown seeds in the bunker 11 is occupied by the seeds, which, as the sowing process goes, enter the bunker 11 through the loading nozzle 7 from the main bunker 2. This allows you to continuously support live in a bunker 11 the optimum level of seed that contributes

better quality of the sowing machine 12.

Preventing the clogging of seeds in the loading nozzle 7 provides the stem 17 with radial vanes 18, which reciprocates. The radial vanes 18, together with the dynamic oscillations of the coulter suspension 13, loosen the seed layers in the feed tube 7 and transfer them to a fluidized state, favorable for moving the seeds along the feed tube 7 under the action of gravity. The rod 17 receives a reciprocating movement from the crank 4 of the shaft of the tedder 3, which is driven from the driving wheels of the planter. When moving from the working position to the transport rack 16 keeps the sowing unit 12 in the transport position.

Claims (1)

Claim A seeder containing pivotally mounted on the frame by means of radial sleeves openers with sowing devices installed in them and bunkers that are connected to the branch pipe with the main bunker equipped with a shaft with a seed agitator, which is distinguished by the fact that, in order to simplify the design of the seeder and improve the uniformity of seed loading bunkers of openers, each nozzle is made of rigid material and pivotally connected to the main bunker and the opener bunker, and inside the nozzle there is a rod with radial blades, which crank means pivotally connected to the shaft tedder drill.
